Description

The invention relates to a temperature control device for a motor vehicle, in particular for a motor vehicle, according to the preamble of patent claim 1. Furthermore, the invention relates to a motor vehicle, in particular a motor vehicle.

The DE 10 2017 220 376 A1 A cooling system for a motor vehicle can be seen as known, with an electrical energy storage device for driving the motor vehicle. Furthermore, the reveals DE 10 2019 132 688 A1 a heat management system for a motor vehicle, with an engine chiller circuit in which a chiller, an electrical energy storage and an electric motor are arranged. In addition, from the US 3,336,319 B2 a thermal management system for a vehicle is known.

The object of the present invention is to create a temperature control device for a motor vehicle and a motor vehicle so that a particularly advantageous temperature control can be realized.

This object is achieved according to the invention by a temperature control device with the features of patent claim 1 and by a motor vehicle with the features of patent claim 15. Advantageous embodiments of the invention are the subject of the dependent claims.

A first aspect of the invention relates to a temperature control device for a motor vehicle, in particular for a motor vehicle preferably designed as a passenger car. This means that the motor vehicle, which is preferably designed as a motor vehicle, in particular as a passenger car, has the temperature control device in its completely manufactured state. In particular, for example, by means of the temperature control device, a particularly advantageous temperature control, that is, cooling and/or heating, of the interior of the motor vehicle, also referred to as the passenger cell or passenger compartment, can be realized, in the interior of which people, such as the driver of the motor vehicle, can stay while the motor vehicle is driving . For this purpose, the temperature control device has a valve device which has at least or exactly seven connections.

In particular, it is conceivable that the valve device has, in particular precisely, eight connections. In addition, the temperature control device has a temperature control circuit through which a preferably liquid temperature control fluid can flow, which is also referred to as a circuit or circuit. The temperature control fluid is preferably a liquid and therefore liquid. For example, the temperature control fluid can comprise at least water. The temperature control circuit has a first strand which is fluidly connected to a first of the connections and fluidly to a second of the connections. This means that the first strand is connected to the first connection and to the second connection and is therefore fluidly connected to the valve device via the first connection and the second connection.

The valve device has, for example, a valve device housing and a valve device element, which can be moved relative to the valve device housing, for example, into several positions, in particular rotationally and/or translationally. For example, the valve device element can be arranged at least partially in the valve device housing. In this case, for example, the first strand is fluidly connected to the valve device housing via the first connection and the second connection. The feature that a respective one of the connections within the valve device is fluidly connected to a respective other one of the connections is to be understood as meaning that the one connection and the other connection within the valve device housing are fluidly connected to one another, so that within the valve device, that is Within the valve device housing, the temperature control fluid can flow or flows from one connection to the other connection or vice versa. In at least or exactly one of the positions of the valve device element, for example, the one connection within the valve device, that is to say within the valve device housing, is fluidly connected to the other connection, so that one connection is then fluidly connected via the valve device element to the other connection, i.e. the valve device element fluidly connects one connection to the other connection. Expressed again in other words, the valve device element then releases a fluidic connection between the one connection and the other connection within the valve device, that is to say within the valve device housing, so that the one connection and the other connection in the valve device housing, that is to say within the valve device housing, are fluidly connected to each other. The feature that, for example, one connection and the other connection in the valve device, that is, within the valve device, are fluidically separated from one another, is to be understood as meaning that the one connection and the other connection within the valve device, that is, within the valve device housing, are fluidly separated from each other, so that within the valve device, that is, within the valve device housing, the temperature control fluid cannot flow from one connection to the other connection or vice versa. Thus, for example, in at least one other of the positions or in all other positions of the valve device element, one connection is fluidly separated from the other connection within the valve device, that is to say within the valve device housing, or vice versa, by means of the valve device element. Expressed again in other words, the fluidic connection between the one connection and the other connection within the valve device, that is to say within the valve device housing, is then interrupted by means of the valve device element, so that the temperature control fluid within the valve device, that is to say within the valve device housing, does not come from the one connection to the other connection and not from the other connection to the one connection.

The first strand has at least a first branch, which is therefore a first part of the first strand. In the first branch, at least or exactly one drive machine that can be tempered, that is to be cooled and/or heated, by means of the temperature control fluid flowing through the first branch is arranged, by means of which the motor vehicle can be driven. For example, the temperature control fluid flowing through the first strand or the first branch can flow through at least part of the drive machine, whereby the drive machine can be tempered, that is, cooled and / or heated, in particular by a heat exchange between the temperature control fluid flowing through the first branch and the drive machine. The drive machine is preferably designed as an electric machine, which can be operated, for example, in a motor mode and thus as an electric motor, by means of which the motor vehicle can be driven, in particular purely electrically. Very preferably, the drive machine, in particular the electrical machine, is a high-voltage component whose electrical voltage, in particular electrical operating or nominal voltage, is preferably greater than 50 volts, in particular greater than 60 volts, and most preferably is several 100 volts. This makes it possible to achieve particularly high electrical power for, in particular electrical, driving of the motor vehicle.

The first strand also has at least one second branch, which is therefore a second part of the first strand. The second branch is fluidically connected in parallel to the first branch. A first heat exchanger is arranged in the second branch, through which the temperature control fluid flowing through the second branch can flow. The first heat exchanger is also arranged in a refrigerant circuit which is provided in addition to the temperature control circuit and through which a refrigerant can flow, so that the refrigerant can also flow through the first heat exchanger. Via the first heat exchanger, heat can be exchanged or transferred between the temperature control fluid flowing through the first heat exchanger and the refrigerant flowing through the first heat exchanger. Preferably, the refrigerant is provided in addition to the temperature control fluid and is a different fluid from the temperature control fluid. Furthermore, it is preferably provided that the refrigerant circuit is fluidly separated from the temperature control circuit. Preferably, the refrigerant circuit and the refrigerant are components of an air conditioning system of the motor vehicle, also known as an air conditioning system, wherein the air conditioning system can be part of the temperature control device. Since the first heat exchanger is arranged both in the second branch and in the refrigerant circuit, the first heat exchanger is also part of the air conditioning device. The air conditioning device is designed to control the temperature of air to be supplied to the interior of the motor vehicle and also referred to as interior air. By tempering, in particular cooling and/or heating, the air to be supplied to the interior, the interior can be tempered, that is, cooled and/or heated.

For example, the first heat exchanger is a cooling device or the first heat exchanger can be operated as a cooling device, wherein the refrigerant can be cooled by means of the cooling device, in particular in that heat can be transferred from the refrigerant to or to the temperature control fluid flowing through the first heat exchanger via the first heat exchanger or is transferred. In particular, the first heat exchanger can be a capacitor or can be operated as a capacitor, wherein the refrigerant can be condensed by means of the condenser, in particular by cooling the refrigerant, that is in particular by transferring heat from the refrigerant to or onto the second via the condenser Temperature control fluid flowing through the branch can be transferred or is transferred. The air conditioning device can have a refrigerant compressor arranged in the refrigerant circuit and simply referred to as a compressor or compressor, by means of which the refrigerant can be conveyed and compressed through the refrigerant circuit.

The temperature control circuit has a second strand, which is fluidly connected to a third of the connections and fluidly to a fourth of the connections. This means that the second strand is connected to the third connection and to the fourth connection and is therefore fluidly connected to the valve device, in particular to the valve device housing, via the third connection and via the fourth connection. Arranged in the second strand is an electrical energy storage device to be tempered, that is to say cooled and/or heated, by means of the temperature control fluid flowing through the second strand, for the, in particular electrochemical, storage of electrical energy. Preferably, the electrical energy storage is a high-voltage component whose electrical voltage, in particular electrical operating or nominal voltage, is preferably greater than 50 volts, in particular greater than 60 volts, and most preferably is several 100 volts. In particular, it is conceivable that the drive machine, in particular the electrical machine, can be supplied with the electrical energy stored in the energy storage, whereby the electrical machine can be operated in motor mode.

The temperature control circuit also has a third strand, which is fluidly connected to a fifth of the connections and to a sixth of the connections. This means that the third strand is connected to the fifth connection and to the sixth connection and is therefore fluidly connected to the valve device, in particular to the valve device housing, via the fifth connection and the sixth connection. An electrical heating element is arranged in the third strand, by means of which the temperature control fluid flowing through the third strand can be heated electrically, that is, using electrical energy. In particular, the electrical heating element can be operated by means of the electrical energy stored or to be stored in the electrical energy storage, so that the electrical heating element can use the electrical energy stored in the electrical energy storage to heat the temperature control fluid flowing through the third strand. It can be seen that the third strand is a third part of the temperature control circuit.

The temperature control circuit also has a fourth strand, which is a fourth part of the temperature control circuit. The fourth strand is fluidly connected to a seventh of the connections. This means that the fourth strand is connected to the seventh connection and is therefore fluidly connected to the valve device, in particular fluidly to the valve device housing, via the seventh connection. It is conceivable that the fourth strand is fluidly connected to an eighth of the connections. This means that the fourth strand is connected, for example, to the eighth connection and is therefore fluidly connected to the valve device, in particular fluidly to the valve device housing, via the eighth connection.

Alternatively, it is conceivable that the fourth strand is fluidly connected to the first strand at a mouth point and thus opens into the first strand, for example, at the mouth point, for example the mouth point in the flow direction of the temperature control fluid flowing through the first strand downstream of the first connection and upstream of the second Connection, in particular upstream of the first branch and the second branch, can be arranged. Thus, for example, the fourth strand is fluidly connected to the second connection via the first strand, so that, for example, the eighth connection can be eliminated. For example, a line area of the first strand extends from the mouth point to the second connection, so that, for example, the fourth strand is then fluidly connected to the second connection via the mouth point and the line area, that is to say is in particular connected to the second connection. The line area can therefore be flowed through, for example, by the temperature control fluid flowing through the first strand and by the temperature control fluid flowing through the fourth strand. In other words, for example, the temperature control fluid flowing through the fourth strand flows on its way through the fourth strand to the valve device or in the direction of the valve device through the mouth point or over the mouth point and through the length region and then via the second connection into the valve device or into the valve device housing into it.

An ambient air cooler, also referred to as a radiator, is arranged in the fourth strand and, because the ambient air cooler is arranged in the fourth strand, the temperature control fluid flowing through the fourth strand can flow through it. Via the ambient air cooler, the temperature control fluid flowing through the fourth strand and thus the ambient air cooler can be cooled by means of ambient air that flows around the ambient air cooler. In particular, when the motor vehicle is traveling forward, the ambient air mentioned, that is to say the airstream formed by the ambient air, can flow around the ambient air cooler in an environment of the motor vehicle, whereby the temperature control fluid can be advantageously cooled via the ambient air cooler. In particular, ambient air is to be understood as meaning air which is arranged overall in the aforementioned environment of the motor vehicle. By means of the ambient air cooler, which is also referred to as a high-temperature cooler or is designed as a high-temperature cooler (HT cooler), the temperature control fluid and thus, for example, via the temperature control fluid Electrical energy storage and / or the drive machine are effectively cooled, so that a particularly advantageous and particularly needs-based temperature control can be achieved. By using the valve device designed, for example, as a switching valve, which can be switched into different switching states, for example, in particular using electrical energy, the temperature control fluid can be guided or directed particularly as required, whereby the number of actuators can be kept low. As a result, a particularly advantageous temperature control can be achieved in a particularly weight-, cost- and space-efficient manner. For example, by switching the valve device between the switching states, the valve device element can be moved between the respective positions. In other words, for example, the valve device element can be moved into the respective positions by switching the valve device into the respective switching states. When we talk about the ambient air cooler below, unless otherwise stated, this means the first ambient air cooler, i.e. the ambient air cooler arranged in the fourth line.

In order to be able to realize a particularly advantageous temperature control, it is provided in one embodiment of the invention that a second heat exchanger is arranged in the second strand, through which the temperature control fluid flowing through the second strand can flow, which is provided in addition to the first heat exchanger. The second heat exchanger is also arranged in the refrigerant circuit and can therefore also be flowed through by the refrigerant. Via the second heat exchanger, heat can be transferred or exchanged between the temperature control fluid flowing through the second heat exchanger and the refrigerant flowing through the second heat exchanger. For example, the second heat exchanger is a chiller or the second heat exchanger is also referred to as a chiller, so that, for example, heat can be transferred from the temperature control fluid to the refrigerant via the second heat exchanger, whereby the temperature control fluid can be cooled.

For example, the air conditioning device has an evaporator provided in addition to the first heat exchanger and in addition to the second heat exchanger for evaporating the refrigerant, the evaporator being arranged in the refrigerant circuit. For example, air, in particular the air to be supplied to the interior, can flow around the evaporator. Via the evaporator, heat can be transferred from the air flowing around the evaporator and, for example, to be supplied to the interior to the refrigerant, whereby the air flowing around the evaporator, which, for example, can be supplied to the interior or is introduced into the interior, is to be cooled or is cooled. It can be seen that, for example, heat can be transferred to or to the refrigerant via the second heat exchanger and optionally via the evaporator, in particular in that heat can be transferred from the temperature control fluid to or on the refrigerant via the second heat exchanger and, if necessary, in that from The air flowing around the evaporator can transfer heat via the evaporator to or onto the refrigerant. In particular, heat can be transferred from the energy storage to the temperature control fluid and subsequently from the temperature control fluid via the second heat exchanger to the refrigerant, so that, for example, by means of the temperature control device, the heat transferred or transferred from the temperature control fluid, in particular via the second heat exchanger, to the refrigerant and, for example, optionally from Air flowing around the evaporator via the evaporator or transferred to the refrigerant can be used, for example, to heat the interior. This allows the interior to be heated particularly energy-efficiently.

For example, the air conditioning device can be operated in a heat pump mode and thus as a heat pump. In particular in the heat pump operation and thus by means of the heat pump, the air to be supplied to the interior can be heated by means of heat which is contained in the refrigerant and is or has been transferred to or on the refrigerant, in particular via the second heat exchanger and/or the evaporator. Very preferably, the air conditioning device can, in particular, be operated in a compression refrigeration machine operation and thus as a compression refrigeration machine, by means of which the air to be supplied to the interior can be cooled, in particular in the manner described via the evaporator. Furthermore, heat can be transferred to or to the temperature control fluid in that heat is transferred from the drive machine to the temperature control fluid and, for example, subsequently from the temperature control fluid, in particular via the second heat exchanger, to the refrigerant, so that, for example, heat that is also provided or can be provided by the drive machine can be used to heat the interior, especially in heat pump operation. For example, heat that is transferred from the refrigerant to the temperature control fluid via the first heat exchanger can be used to heat the energy storage and/or the drive machine, in particular as needed, which is particularly advantageous at low ambient or outside temperatures.

Since the temperature control fluid is preferably liquid, i.e. a liquid, the first heat exchanger is, for example, designed or operable as a liquid-cooled, in particular water-cooled, condenser (WCC).

In order to be able to realize a particularly advantageous temperature control in a particularly needs-based manner, it is provided in a further embodiment of the invention that a proportional valve which is provided in addition to the valve device and is external to the valve device is arranged in the second branch upstream or downstream of the first heat exchanger, whereby the valve device is external to the proportional valve, that is to say an additional component external to the proportional valve.

The proportional valve can be switched, for example, between a first valve state and a second valve state. In the second valve state, the proportional valve releases the second branch more or further than in the first valve state, so that, for example, the proportional valve has a flow cross section through which the temperature control fluid flowing through the second branch can flow, which is larger in the second valve state than in the first valve state. In particular, the first valve state is a closed state in which the second branch is closed, that is fluidically blocked, by means of the proportional valve, and therefore the flow cross section, also referred to as the flow cross section, is 0, so that, for example, in the first valve state, in particular in the closed state, a supply of the first heat exchanger with the temperature control fluid via the proportional valve or a flow of the temperature control fluid through the first heat exchanger does not occur. The second valve state is, for example, an open state in which the proportional valve releases the second branch, in particular releases it more strongly than in the first valve state, so that in the second valve state, in particular in the open state, the flow cross section is greater than 0. Thus, in the second valve state, the heat exchanger can be supplied with the temperature control fluid via the proportional valve or in the second valve state, the proportional valve allows the temperature control fluid to flow through the first heat exchanger or the proportional valve allows the temperature control fluid to flow through the first heat exchanger. The proportional valve can be switched between the valve states, i.e. in the valve states, and can also be brought into several intermediate states. In particular, the proportional valve has a proportional valve housing and a proportional valve element, which can be moved relative to the proportional valve housing into a first switching position which causes the first valve state and into a second switching position which causes the second valve state. Furthermore, the proportional valve element can be moved relative to the proportional valve housing into a plurality of intermediate positions which bring about the respective intermediate states, in particular at least substantially continuously and/or continuously, the respective intermediate position being between the switching positions. In the respective intermediate state or in the respective intermediate position, the proportional valve or the proportional valve element blocks the second branch more strongly than in the second valve state, and in the respective intermediate state, in particular the respective intermediate position, the proportional valve releases the second branch and thereby opens it more strongly or further than in the first valve state. Thus, for example, in the respective intermediate state, the flow cross section is larger than in the first valve state and smaller than in the second valve state, the flow cross section in the respective intermediate state having a respective value and the respective values being different from one another and in particular greater than 0. In particular, for example, the proportional valve element can be moved at least substantially continuously into the switching positions and into the intermediate positions. The proportional valve thus enables an adjustment of different volume and/or mass flows of the temperature control fluid flowing through the second branch and thus the first heat exchanger and in particular larger than 0, in particular in that the proportional valve or the proportional valve element is in the intermediate states or in the intermediate positions and in the second valve state or into the second switching position can be switched or moved, and in particular the proportional valve enables a fluidic blocking of the second branch, in particular in that the proportional valve or the proportional valve element can be switched or moved into the first valve state or into the first switching position. It is therefore particularly conceivable that in the respective intermediate position or in the respective intermediate state the flow cross section is greater than 0 and greater than in the first valve state or the first switching position and smaller than in the second valve state or in the second switching position. In particular, it is conceivable that by moving the proportional valve element into the switching positions and into the intermediate positions, the flow cross section can be at least substantially continuously and / or continuously varied, that is, changeable, in particular between, for example, 0 Minimum value, in particular in the first valve state, and a maximum value that is larger than the minimum value and compared to 0, in particular in the second valve state. The proportional valve is therefore a throttle valve or can be operated as a throttle valve, since in the respective intermediate state the temperature control fluid flowing through the second branch can or is flowed through the first heat exchanger, but is throttled compared to the second valve state. In other words, in the respective intermediate state, the flow through the first heat exchanger is or will be throttled compared to the second valve state, whereby a particularly needs-based supply of the first heat exchanger with the temperature control fluid via the proportional valve (throttle valve) or a particularly needs-based flow through the first heat exchanger can be realized. In particular, for example, the proportional valve is designed as a two/two throttle valve. Expressed again in other words, a needs-based supply or flow through the first heat exchanger with or from the temperature control fluid can be realized, in particular adjustable, by means of the proportional valve, in particular an advantageous throttling of the first heat exchanger, that is to say a flow of the temperature control fluid through the first heat exchanger, can be adjusted as required .

A further embodiment is characterized in that a second ambient air cooler is arranged in the second branch, provided in addition to the ambient air cooler and in addition to the heat exchangers, via which the temperature control fluid flowing through the second branch and thereby the second ambient air cooler and the first heat exchanger by means of the second Ambient air cooler is to be cooled by ambient air flowing around it. For example, the second ambient air cooler is arranged upstream of the first heat exchanger and in particular downstream of the first connection. In particular, it can be provided that the proportional valve is arranged downstream of the first heat exchanger and in particular upstream of the second connection. The second ambient air cooler is, for example, a low-temperature cooler or is also referred to as a low-temperature cooler (NTK). By using the optionally provided second ambient air cooler, a particularly advantageous temperature control, in particular cooling, of the temperature control fluid can be achieved. In particular, by using the proportional valve, a particularly advantageous throttling of the second ambient air cooler or of the temperature control fluid flowing through the second ambient air cooler can also be achieved.

A further embodiment provides that a check valve is arranged in the second strand downstream of the electrical energy storage and upstream of the fourth connection, which prevents a flow of the temperature control fluid running from the fourth connection through the check valve and towards the energy storage, in particular automatically or independently prevents, and allows an opposite flow, in particular automatically or independently, running from the energy storage through the check valve and towards the fourth connection. As a result, an undesirable flow of the temperature control fluid can be avoided in a particularly simple manner, whereby a particularly advantageous temperature control can be achieved.

In order to be able to provide a particularly needs-based flow of the temperature control fluid and thus a particularly needs-based temperature control, in particular of the interior, it is provided in a further embodiment of the invention that a pump is arranged in the first line, by means of which the temperature control fluid can be conveyed.

It has also proven to be particularly advantageous if a pump for conveying the temperature control fluid is arranged in the second line, as a result of which the temperature control fluid can be conveyed particularly in line with requirements.

In order to be able to convey the temperature control fluid in a particularly needs-based and energy-efficient manner, it is provided in a further embodiment of the invention that the pump arranged in the first line and also referred to as the first pump and/or the pump arranged in the second line and also referred to as the second pump, In addition to the first pump, the pump provided is designed as an electric pump, therefore as an electrically operable pump. When we talk about pumps below, this refers to the first pump and the second pump, unless otherwise stated.

In a further, particularly advantageous embodiment of the invention, it is provided that the valve device can be switched to a first switching state. For this purpose, for example, the valve device element can be moved relative to the valve device housing into at least or exactly a first position which brings about the first switching state. In the first switching state, the first strand and the fourth strand are fluidly connected to one another via the valve device, that is to say within the valve device and in particular within the valve device housing, and are therefore connected in series to one another in fluid terms, whereby the first strand and the fourth strand form a first overall strand. In the first switching state, the third strand and the second strand are fluidly connected to one another via the valve device, that is to say within the valve device, and are therefore connected in series to one another, whereby the third strand and the second strand form a second overall strand. In addition, it is provided that in the first switching state there is no fluidic connection of the first overall strand to the second overall strand via the valve device, so that the first overall strand and the second overall strand are not fluidly connected to one another via the valve device. In particular, it is conceivable that in the first switching state the pumps are activated, in particular simultaneously, and thus run, in particular simultaneously, so that, for example, in the first switching state the temperature control fluid is conveyed, in particular simultaneously, by means of both pumps. Thus, the pumps are connected in parallel to one another, that is to say that the pumps work in parallel to one another or independently of one another and thus convey the temperature control fluid, in particular in such a way that, for example, by means of the first pump, the temperature control fluid in relation to the first overall strand and the second overall strand exclusively through the first The entire strand is conveyed, and by means of the second pump, for example, the temperature control fluid, based on the first overall strand and the second overall strand, is conveyed exclusively through the second overall strand. In particular, it is provided that in the first switching state the first connection within the valve device, in particular in relation to the connections exclusively, with the eighth connection, the second connection within the valve device, in particular in relation to the or all connections exclusively, with the seventh connection, the third connection within the valve device, in particular in relation to the connections exclusively, with the fifth connection, the fourth connection within the valve device, in particular in relation to the or all connections exclusively, with the sixth connection, the fifth connection within the valve device, in particular in relation to the or all connections exclusively, with the third connection, the sixth connection within the valve device, in particular in relation to the or all connections exclusively, with the fourth connection, the seventh connection within the valve device, in particular in relation to the or all connections exclusively, with the second connection, and the eighth connection within the valve device, in particular with regard to the or all connections exclusively, is fluidly connected to the first connection.

In the present disclosure, ordinal words such as "first", "second", "third", etc. do not necessarily indicate an order or a necessarily intended set of elements to which the ordinal words refer, such as when of a fourth element What we are talking about is that a first element, a second element and a third element do not necessarily have to be provided, but the ordinal number words are used in particular to be able to conceptually distinguish terms to which the ordinal number words refer from one another, in order to be able to refer to them To be able to clearly refer to terms.

In order to be able to direct or guide the temperature control fluid particularly advantageously and thus to achieve particularly good temperature control, it is provided in a further embodiment of the invention that the valve device can be switched, in particular discretely, into a second switching state. For example, the valve device can be switched, in particular discretely, between the first switching state and the second switching state. For example, the valve device element can be moved, in particular discretely, between the first position and at least or exactly one second position that causes the second switching state relative to the valve device housing. In particular, the feature that the valve device can be switched discretely between one switching state and another switching state can be understood to mean that the valve device can be switched between one switching state and the other switching state, but not into a switching state between the switching states Intermediate state can be switched, so that, for example, the valve device element can be moved between the first position and the second position, in particular discretely, but cannot be moved into an intermediate position lying between the first position and the second position.

In the second switching state, the first strand, the third strand and the second strand are fluidly connected to one another via the valve device, that is to say within the valve device, and are therefore fluidically connected in series to one another, whereby the first strand, the third strand and the second strand have a third Form the entire strand. In the second switching state, there is no fluidic connection between the third overall strand and the fourth strand via the valve device, so that in the second switching state the third overall strand is not fluidly connected to the fourth strand via or by means of the valve device. Thus, in particular in the second switching state, for example In terms of fluid flow, the pumps are connected in series to one another. In particular, it is conceivable that in the second switching state the pumps run simultaneously, and are therefore activated at the same time, so that, for example, in the second switching state the temperature control fluid is conveyed, in particular simultaneously, by means of both pumps, or in the second switching state the temperature control fluid is related to the pumps conveyed by only one of the pumps, so that, for example, in the second switching state relative to the pumps, only one of the pumps is running and the other pump is deactivated. In particular, it is conceivable that in the second switching state there is no flow of the temperature control fluid through the fourth strand and/or, for example, there is no active delivery of the temperature control fluid through the fourth strand caused by a conveying device. In particular, it can be provided that in the second switching state the first connection within the valve device, in particular within the valve device housing, in particular in relation to the or all connections exclusively, with the fourth connection, the second connection within the valve device, in particular in relation to the or all connections exclusively, with the sixth connection, the third connection within the valve device, in particular in relation to the or all connections exclusively, with the fifth connection, the fourth connection within the valve device, in particular in relation to the or all connections exclusively, with the first connection, the fifth connection within the valve device, in particular in relation to the or all connections exclusively, is fluidly connected to the third connection and the sixth connection within the valve device, in particular in relation to the or all connections exclusively, is fluidly connected to the second connection, for example the seventh connection within the valve device, in particular in relation to the or all connections exclusively, is fluidly connected to the eighth connection and the eighth connection within the valve device, in particular in relation to the or all connections exclusively, is fluidly connected to the seventh connection, or wherein the seventh connection within the valve device is fluidly connected is fluidically separated from the or all other connections and, for example, the eighth connection within the valve device is fluidly separated from the or all other connections.

In order to be able to implement a particularly needs-based guidance or line of the temperature control fluid and thus a particularly needs-based and advantageous temperature control, it is provided in a further embodiment of the invention that the temperature control device has a connecting line, which is at a downstream of the seventh connection and upstream of the fourth Strand arranged ambient air cooler arranged in the fourth strand, first connection point is fluidically connected to the fourth strand and at a second connection point arranged downstream of the third connection and upstream of the energy storage in the second strand is fluidly connected to the second strand. The fourth strand has a first length range that extends from the seventh connection to the first connection point, in particular continuously and thus without interruption, and a second length range that extends from the first connection point to. For example, the second length range extends from the first connection point to the eighth connection, in particular continuously. Furthermore, it is conceivable that the second length range extends from the first connection point to the mouth point, in particular continuously. Furthermore, the second strand has a third length range that extends from the third connection to the second connection point, in particular continuously, and a fourth length range that extends from the second connection point to the fourth connection, in particular continuously.

It has proven to be particularly advantageous if the valve device can be switched, in particular discretely, into a third switching state, with the valve device element, for example, being movable, in particular discretely, into at least or exactly one third position which brings about the third switching state. Thus, for example, the valve device can be switched, in particular discretely, between the third switching state and the first switching state or between the third switching state and the second switching state or between the third switching state, the second switching state and the first switching state, so that, for example, the valve device element, in particular discretely, between the third position and the first position or between the third position and the second position or between the third position, the second position and the first position relative to the valve device housing.

In the third switching state, the second length range is fluidly connected to the first strand via the valve device, that is to say within the valve device, whereby the connecting line, the second length range and the first strand are fluidically connected in series to one another and thereby form a fourth overall strand, which via the valve device, that is to say within the valve device, is fluidly connected to the third strand. In the third switching state the fourth length range is fluidly connected to the third strand via the valve device, i.e. within the valve device, whereby the fourth overall strand and the fourth length range are fluidically connected in parallel to one another and in fluid series in series with the third strand. In the third switching state, the third strand is fluidly connected to the third length range via the valve device, that is, within the valve device, whereby the third strand is fluidically connected in series to the third length range. In the third switching state, there is no fluidic connection of the first length range to the strands via the valve device, so that the first length range is not fluidly connected to the strands via or by means of the valve device. In addition, it is provided that in the third switching state at least a predominant part of the temperature control fluid flowing through the third length range, the connecting line and the fourth length range bypasses the first length range on its way through the third length range, the connecting line and the fourth length range. In particular, in the third switching state it is provided that the first connection within the valve device, in particular with regard to the or all connections exclusively, is fluidly connected to the eighth connection. The second connection is fluidly connected within the valve device, in particular with respect to the or all connections exclusively, with the sixth connection or with the sixth connection and with the fourth connection, such that the temperature control fluid flowing through the second connection exclusively with respect to the or all connections flows to and through the sixth port. Furthermore, it is provided, for example, that the third connection within the valve device is fluidly connected to the fifth connection, in particular with regard to the or all connections exclusively. Furthermore, for example, the fourth connection within the valve device, in particular with respect to the or all connections, is fluidly connected exclusively to the sixth connection or to the sixth connection and the second connection, such that the temperature control fluid flowing through the fourth connection is related to the or all connections flows exclusively to and through the sixth port. Furthermore, for example, the fifth connection within the valve device, in particular with regard to the or all connections exclusively, is fluidly connected to the third connection. The sixth connection is fluidly connected within the valve device, in particular in relation to the or all connections exclusively, to the fourth connection and to the second connection, so that the temperature control fluid flowing through the sixth connection, in relation to the or all connections, exclusively from or from the fourth connection and the second connection. The eighth connection is fluidly connected to the first connection within the valve device, in particular with regard to the or all connections exclusively. Furthermore, it is preferably provided that in the third switching state the seventh connection within the valve device is fluidically separated from the or all other connections. Thus, for example, in the third switching state, there is no flow of the temperature control fluid through the first length range.

In order to be able to implement a particularly advantageous and needs-based temperature control, it is provided in a further embodiment of the invention that the valve device can be switched, in particular discretely, into a fourth switching state. In the fourth switching state, the first strand is fluidly connected to the third strand via the valve device, and in the fourth switching state, the third strand is fluidly connected to the first length range via the valve device, whereby the first strand, the third strand, the first length range, the connecting line and the fourth length region are fluidly connected to one another, in particular via the valve device, and are therefore fluidically connected in series to one another. As a result, the first strand, the third strand, the first length range, the connecting line and the fourth length range form a fifth overall strand. In the fourth switching state, there is no fluidic connection of the third length range to the strands via the valve device, so that the third length range is not fluidly connected to the strands via the valve device. In addition, there is no fluidic connection of the second length range to the strands via the valve device, so that the second length range is not fluidly connected to the strands via the valve device. In addition, in the fourth switching state it is provided that at least a predominant part of the temperature control fluid flowing through the fifth overall strand passes through the second length range and thereby the ambient air cooler arranged in the second length range and the third length range of the second strand and thus in particular the bypasses the second heat exchanger arranged in the third length range. In particular, it is provided that in the fourth switching state the first connection within the valve device, in particular in relation to the or all connections exclusively, with the fourth connection, the second connection within the valve tileinrichtung, in particular with reference to the or all connections exclusively, with the sixth connection, the fourth connection within the valve device, in particular with reference to the or all other connections exclusively, with the first connection, the fifth connection within the valve device, in particular with reference to the or all connections exclusively, with the seventh connection, the sixth connection within the valve device, in particular in relation to the or all connections exclusively, with the second connection and the seventh connection within the valve device, in particular in relation to the or all connections exclusively, with the fifth connection is fluidly connected, while, for example, the third connection within the valve device is separated from the or all other connections and while, for example, the eighth connection within the valve device is fluidly separated from the or all other connections. This means that, for example, there is no flow of the temperature control fluid through the third length range. Alternatively or additionally, for example, there is no flow of the temperature control fluid through the second length region.

Finally, in order to realize a particularly advantageous and needs-based temperature control, it has proven to be particularly advantageous if the valve device can be switched, in particular discretely, into a fifth switching state. In the fifth switching state, the third strand is fluidly connected to the first length range via the valve device, and the third strand is fluidly connected to the fourth length range via the valve device, whereby the first length range, the connecting line, the fourth length range and the third strand, in particular via the valve device, are fluidly connected to one another and are therefore fluidically connected in series to one another. As a result, the first length range, the connecting line, the fourth length range and the third strand form a sixth overall strand. In particular, in the fifth switching state it is provided that there is no fluidic connection of the third length range to the strands via the valve device, so that, for example, the third length range is not fluidly connected to the strands via the valve device. It can therefore be provided that in the fifth switching state there is no flow of the temperature control fluid through the third length range. In the fifth switching state, there is no fluidic connection between the second length range and the strands via the valve device. For example, in the fifth switching state, there is no flow of the temperature control fluid through the second length range. In the fifth switching state, it is provided that at least a predominant part of the temperature control fluid flowing through the sixth overall strand on its way through the sixth overall strand bypasses the second length range and thereby the ambient air cooler arranged in the second length range and preferably also the third length range of the second strand. Furthermore, in the fifth switching state it is provided that there is no fluidic connection of the first strand to the sixth overall strand via the valve device, so that in the fifth switching state the first strand is not connected to the sixth overall strand via the valve device. In particular, it is conceivable that in the fifth switching state the pumps run, in particular simultaneously, and are therefore activated, so that, for example, the temperature control fluid is conveyed, in particular simultaneously, by means of both pumps. Thus, so to speak, the pumps are connected in parallel or the pumps work in parallel, so that, for example, the first pump conveys the temperature control fluid in relation to the sixth overall line and the first line conveys the temperature control fluid exclusively through the first line, and so that, for example, the second pump in relation to the sixth overall line and The first strand conveys the temperature control fluid exclusively through the sixth overall strand.

In the fourth switching state, it is conceivable that in the fourth switching state both pumps are activated, in particular simultaneously, and thus run, so that, for example, in the fourth switching state the temperature control fluid is conveyed by means of both pumps, in particular simultaneously, or in the fourth switching state this is Temperature control fluid is conveyed exclusively by means of one of the pumps, while the other pump in particular can be deactivated. Furthermore, it is conceivable that in the third switching state the pumps are activated, in particular simultaneously, and thus run simultaneously, so that, for example, in the third switching state the temperature control fluid is conveyed, in particular simultaneously, by means of both pumps.

In particular, it can be provided that in the fifth switching state the first connection within the valve device, in particular in relation to the or all connections exclusively, with the second connection and the second connection within the valve device, in particular in relation to the or all connections exclusively, with the first Connection is fluidly connected. Furthermore, it is conceivable that in the fifth switching state the third connection is fluidically separated from the or all other connections within the valve device. Furthermore, it is conceivable that in the fifth switching state, the fourth connection within the valve device, in particular related to the or all connections exclusively, with the sixth connection, the fifth connection within the valve device, in particular related to the or all connections exclusively, with the seventh connection, the sixth connection within the valve device , in particular with reference to the or all connections exclusively, with the fourth connection and the seventh connection within the valve device, in particular with reference to the or all connections exclusively, with the fifth connection is fluidically connected, for example the eighth connection within the valve device from the respectively is fluidically separated from all other connections.

A second aspect of the invention relates to a motor vehicle, preferably designed as a motor vehicle, in particular a passenger car, which has a temperature control device according to the first aspect of the invention. Advantages and advantageous refinements of the first aspect of the invention are to be viewed as advantages and advantageous refinements of the second aspect of the invention and vice versa.

The invention is based in particular on the following findings: In the case of combined heating, in particular with a fluidic short-circuit of the refrigerant compressor, which is designed, for example, as an electric compressor, and the electric heating element with simultaneous heating of the interior and a requirement to heat the energy storage, a volume or mass flow of the Temperature control fluid through the chiller at cold temperatures may be limited or insufficient due to the stability of the cooling process. This can mean that either only heating of the interior or only heating of the electrical energy storage is possible. In contrast, the invention now makes it possible to heat both the energy storage and the interior in an energy-efficient manner, even at unfavorable, especially low, outside temperatures. Through the described integration of the electrical heating element designed as an additional electric heater, both an advantageous volume and/or mass flow of the temperature control fluid for heating the energy storage, in particular to a target temperature, can be provided and, at the same time, a mass and/or volume flow of the temperature control fluid through the chiller can be advantageously provided limited or kept at such a low level that heating of the interior can be provided by the refrigeration process via a fluidic short-circuit of the refrigerant compressor. This means that heating sources such as the drive machine can be combined or operated in parallel. The integration of components can be designed via the valve device in such a way that the currently required operating modes can be controlled without being influenced by an expansion.

Furthermore, a method for operating a valve device according to the invention is disclosed, whereby advantages and advantageous embodiments of the temperature control device according to the invention are to be viewed as advantages and advantageous embodiments of the method according to the invention.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

1 shows a schematic representation of a first embodiment of a temperature control device 1 for a motor vehicle, preferably designed as a motor vehicle, in particular as a passenger car. The motor vehicle has an interior, also referred to as a passenger cell or passenger compartment, in which people, such as the driver of the motor vehicle, can stay while the motor vehicle is driving. The first embodiment is in 1 until 14 illustrated.

The temperature control device 1 has a valve device 2, also referred to as a switching valve or designed as a switching valve, which will be explained in more detail below. Furthermore, the temperature control device 1 has a temperature control circuit 3 through which a temperature control fluid can flow. The temperature control fluid is preferably liquid, i.e. a liquid. For example, the temperature control fluid can comprise at least water. In the exemplary embodiment shown in the figures, the valve device 2 has exactly eight connections A1, A2, A3, A4, A5, A6, A7 and A8. The valve device 2 has a valve device housing 4 and a valve device element 5, which can be at least partially accommodated in the valve device housing 4. In particular, the valve device element 5 can be moved relative to the valve device housing 4, in particular translationally and/or rotationally. As will be explained in more detail below, the valve device 2 can be switched, in particular discretely, between at least or exactly five switching states. In this regard, it is particularly conceivable that the valve device element 5 can be moved relative to the valve device housing 4, in particular translationally and/or rotationally, between respective switching positions which cause the respective switching states, also referred to as positions, in particular discretely. In particular, the valve device 2 can be switched discretely between the switching states, so that the valve device element 5 can be moved discretely between the switching positions that cause the switching states relative to the valve device housing 4. It is therefore conceivable, for example, that the valve device element 5 can be discretely moved relative to the valve device housing 4 between at least or exactly five switching positions, namely between a first switching position causing a first of the switching states, a second switching position causing a second of the switching states, a second switching position third switching position causing a fourth of the switching states, a fourth switching position causing a fourth of the switching states and a fifth switching position causing a fifth of the switching states. In the respective switching state and thus in the respective switching position, a respective one of the connections A1-8 can be fluidly connected to a respective other one of the connections A1-8 within the valve device 2 and thereby within the valve device housing 4. This is to be understood in particular as meaning that if, in the respective switching state, one connection is fluidly connected to the other connection within the valve device 2, in particular within the valve device housing 4, the valve device element 5 within the valve device housing 4 has a fluid connection between the one connection and releases the other connection, therefore the valve device element 5 is in such a position in which the fluidic connection between the one connection and the other connection is established, that is present, within the valve device housing 4. Furthermore, it is conceivable, for example, that in at least one other of the switching positions one connection is fluidically separated from the other connection by means of or within the valve device 2. This is to be understood as meaning that one connection is then fluidically separated from the other connection by means of the valve device element 5 within the valve device housing 4. Expressed again in other words, the valve device element 5 then fluidly separates one connection from the other connection within the valve device housing 4, so that within the valve device housing 4 the fluidic connection between the one connection and the other connection is interrupted or canceled by means of the valve device element 5.

The temperature control circuit 3 has a first strand 6, which is fluidly connected to the connections A1 and A2, therefore connected to the connections A1 and A2 and is thereby fluidly connected to the valve device housing 4 via the connections A1 and A2, in particular outside the valve device housing 4 The first strand 6 has a first branch ZW1 and a second branch ZW2, through which the temperature control fluid can flow. Out of 1 It can be seen that the branches ZW1 and ZW2 are connected in parallel to one another in terms of fluid flow. At least or exactly one drive machine 7 is arranged in the first branch ZW1, by means of which the motor vehicle can be driven. In particular, the drive machine 7 is designed as an electrical machine, by means of which the motor vehicle can be driven, in particular purely electrically. The drive machine 7 can be tempered, that is, cooled and/or heated, by means of the temperature control fluid flowing through branch ZW1. A first heat exchanger 8 is arranged in the second branch ZW2, which is designed, for example, as a water-cooled condenser (WCC).

For example, in its fully manufactured state, the motor vehicle has at least or exactly two axles arranged one behind the other and thus in succession in the longitudinal direction of the vehicle. The respective axle comprises, for example, at least or exactly two wheels, also referred to as vehicle wheels, which are arranged on sides of the motor vehicle that are opposite one another in the transverse direction of the vehicle. The respective wheel is a respective ground contact element via which the motor vehicle is in the vehicle can be supported or supported vertically downwards on a road. A first of the axles is a front axle, the wheels of which are also referred to as front wheels. A second of the axles is a rear axle, which is arranged behind the front axle in the longitudinal direction of the vehicle. The wheels of the rear axle are also known as rear wheels. For example, the drive machine 7 is assigned to the rear axle, so that the rear wheels, in particular purely, can be driven electrically by means of the drive machine 7, whereby, for example, the motor vehicle can be driven, in particular purely, electrically.

In the exemplary embodiment shown in the figures, the first strand 6 has a third branch ZW3, which is fluidically connected parallel to the second branch ZW2 and fluidically parallel to the first branch ZW1, so that the branches ZW1, ZW2 and ZW3 are fluidly connected parallel to one another are. In the third branch ZW3, at least or in this case exactly one second drive machine 9 is arranged, which is preferably designed as an electrical machine by means of which the motor vehicle can be driven, in particular purely electrically. In particular, the drive machine 9 is assigned to the front axle, so that, for example, the front wheels, in particular purely, can be driven electrically by means of the drive machine 9.

The temperature control device 1 can have an air conditioning device, not shown in the figures, by means of which air that is to be supplied or is supplied to the interior of the motor vehicle can be tempered, that is, cooled and/or heated. For example, the air conditioning device can be operated in a compression refrigeration machine operation and thus as a compression refrigeration machine, by means of which the air to be supplied to the interior can be cooled or is cooled. Alternatively or additionally, it is conceivable that the air conditioning device can be operated in a heat pump mode and thus as a heat pump, by means of which the air to be supplied to the interior can be heated. By cooling the air to be supplied to the interior space, the interior space can be cooled, and by heating the air to be supplied to the interior space, the interior space can be warmed, that is heated. The air conditioning device has a refrigerant circuit provided in addition to the temperature control circuit 3, which is also referred to as a refrigeration circuit or refrigeration circuit and can be flowed through by a refrigerant which is provided in particular in addition to the temperature control fluid and is different from the temperature control fluid. Out of 1 It can be seen that the temperature control device 1 can have a first pump 10 for conveying the temperature control fluid and a second pump 11 for conveying the temperature control fluid if the pumps 10 and 11 are arranged in the temperature control circuit. The pump 11 is provided in addition to the pump 10 and vice versa. The air conditioning device has, for example, a refrigerant compressor provided in addition to the pumps 10 and 11 and arranged in the refrigerant circuit, which is also simply referred to as a compressor or compressor and is designed, for example, as an electric refrigerant compressor. Using the refrigerant compressor, the refrigerant can be conveyed through the refrigerant circuit and compressed. A second heat exchanger 12, also referred to as a chiller, is arranged in the refrigerant circuit and is provided in addition to the heat exchanger 8 and, as will be explained in more detail below, is also arranged in the temperature control circuit 3. The chiller is thus arranged both in the refrigerant circuit and in the temperature control circuit 3, so that both the temperature control fluid and the refrigerant can flow through the chiller (heat exchanger 12). Heat can be exchanged or transferred between the coolant and the temperature control fluid via the chiller, in particular in such a way that heat can be transferred from the temperature control fluid to or to the coolant via the chiller, whereby the temperature control fluid is cooled. Particularly in heat pump operation, heat transferred to or onto the refrigerant via the chiller can be used to heat the air to be supplied to the interior, and therefore to heat the interior.

For example, the air conditioning device has an evaporator provided in addition to the chiller and also in addition to the heat exchanger 8 for evaporating the refrigerant, the evaporator being arranged in the refrigerant circuit. In particular, the heat exchanger 8 is a condenser for condensing the refrigerant. In other words, it is provided that the first heat exchanger 8, which is arranged in the second branch ZW2 and can therefore flow through the second branch ZW2, is also arranged in the refrigerant circuit through which the refrigerant can flow and can therefore also be flowed through by the refrigerant, so that via the first Heat exchanger 8 Heat can be exchanged or transferred between the temperature control fluid and the refrigerant. In particular, the first heat exchanger 8 is or functions as a cooling device for cooling the refrigerant, in particular as a condenser for condensing the refrigerant. Thus, for example, heat can be transferred from the refrigerant to the temperature control fluid via the first heat exchanger 8. Furthermore, for example, heat from the drive machine 7 and from the drive machine 9 can be transferred to the temperature control fluid. The on The heat transferred to the temperature control fluid can be used, in particular in heat pump operation, to heat the interior, in particular in that the heat transferred to the temperature control fluid is transferred to the refrigerant in particular via the chiller (second heat exchanger 12) and is thus transferred to the refrigerant. The heat transferred into the refrigerant can then be used to heat the air to be supplied to the interior and thus the interior.

Out of 1 It can be seen that the pump 10 is arranged in the first strand 6, so that the temperature control fluid can be conveyed through the first strand 6 by means of the pump 10. The pump 10 is connected in series to both the branch ZW1 and the branch ZW2 and also to the branch ZW3, the pump in the present case being arranged upstream of the branches ZW1 and ZW2 and also upstream of the branch ZW3 and downstream of the connection A1.

The temperature control circuit 3 further has a second strand 13, which is fluidly connected to the connections A3 and A4, therefore connected to the connections A3 and A4 and thus fluidly connected to the valve device 2, in particular to the valve device housing 4, via the connections A3 and A4 , connected is. An electrical energy storage device 14 is arranged in the second strand 13, which is also simply referred to as an energy storage device. Thus, the electrical energy storage 14 is to be tempered, that is to be heated and/or cooled, by means of the temperature control fluid flowing through the strand 13. By means of the energy storage 14, that is to say in the energy storage 14, electrical energy can be stored, in particular electrochemically. For example, the drive machines 7 and 9 can be supplied with the electrical energy stored in the energy storage 14, whereby the drive machines 7 and 9 can be operated in motor mode and thus as an electric motor, by means of which the motor vehicle can be driven, in particular purely electrically. Out of 1 It can be seen that the chiller is arranged in the strand 13, in particular in such a way that the chiller is arranged downstream of the connection A3 and upstream of the energy storage 14, in particular upstream of the pump 11, with the pump 11 being arranged, for example, downstream of the connection A3, in particular downstream of the chiller, and upstream of the energy storage 14, which is therefore arranged downstream of the chiller, in particular downstream of the pump 11 and upstream of the connection A4. The pump 11 is thus arranged in the second strand 13.

The temperature control circuit 3 also has a third strand 15, which is fluidly connected to the fifth connection A5 and fluidly to the sixth connection A6, therefore connected to the connections A5 and A6 and thus fluidly to the valve device 2, in particular, via the connections A5 and A6 with the valve device housing 4, is connected. An electrical heating element 16 is arranged in the third strand 15, by means of which the temperature control fluid flowing through the third strand 15 can be heated, that is heated, in particular using electrical energy. For example, the electrical heating element 16 is also referred to as an electric instantaneous water heater (EDH).

Furthermore, the temperature control circuit 3 has a fourth strand 17. In the exemplary embodiment shown in the figures, the temperature control circuit 3 therefore has exactly four strands, namely the strands 6, 13, 15 and 17. It can be seen that the fourth strand 17 is fluidly connected to the connections A7 and A8, i.e. to the Connections A7 and A8 are connected and thus fluidly connected to the valve device 2, in particular to the valve device housing 4, via the connections A7 and A8. In the fourth strand 17, a first ambient air cooler 18, also referred to as a radiator, is arranged, which is also referred to as a high-temperature cooler (HT cooler) or is designed as a high-temperature cooler (HT cooler). The first ambient air cooler 18, also simply referred to as a cooler or first cooler, can be flowed through by the temperature control fluid flowing through the fourth strand 17 and by ambient air, i.e. by air arranged overall in an environment of the motor vehicle, so that the temperature control fluid flowing through the radiator via the radiator by means of the Ambient air flowing around the radiator can be cooled, in particular in such a way that heat can be transferred or transferred from the temperature control fluid flowing through the radiator to the ambient air flowing around the radiator via the radiator (ambient air cooler 18).

In order to be able to adjust a flow of the temperature control fluid through the first heat exchanger 8 in a particularly needs-based manner, a proportional valve 19, which is provided in addition to the valve device 2, is arranged in the second branch ZW2, which is an external valve with respect to the valve device 2 and is provided in addition to the valve device 2 . As a result, for example, the valve device 2 is a valve that is external to the proportional valve 19 and is provided in addition to the proportional valve 19.

Furthermore, in the second branch ZW2 there is an ambient air cooler 18 in addition to the first and in addition to the heat exchangers 8 and 12 and also arranged in addition to the evaporator, a second ambient air cooler 20, via which the temperature control fluid flowing through the second branch ZW2 and thereby the second ambient air cooler 20 and the first heat exchanger 8 can be cooled by means of ambient air which flows around the second ambient air cooler 20.
In addition, a check valve 21 is arranged in the second strand 13 downstream of the electrical energy storage 14 and upstream of the fourth connection A4, which flows the temperature control fluid from the fourth connection A4 through the check valve 21 towards the energy storage 14, in particular independently, that is without active control of the check valve 21 and allows an opposite flow running from the energy storage 14 through the check valve 21 and towards the fourth connection A4 independently, that is, without active control of the check valve 21.

In 1 The first switching state is now illustrated, which is designated Z1. It can therefore be provided that in a method for operating the temperature control device 1, the temperature control device 1 is operated while the valve device 2 is in the first switching state Z1 and thus, for example, the valve device element 5 is in the first switching position. For example, in the first switching state Z1, the pumps 10 and 11 are in operation at the same time, so that the temperature control fluid is conveyed simultaneously, in particular actively, by means of the pumps 10 and 11. In the first switching state Z1, the first strand 6 and the fourth strand 17 are fluidly connected to one another via the valve device 2 and within the valve device 2, that is to say within the valve device housing 4, and are therefore connected in series to one another, whereby the first strand 6 and the fourth Strand 17 form a first overall strand. In the first switching state Z1, the third strand 15 and the second strand 13 are fluidly connected to one another via the valve device 2, that is to say within the valve device 2 or within the valve device housing 4, and are therefore fluidically connected in series to one another, whereby the third strand 15 and the second Strand 13 form a second overall strand. In the first switching state Z1, there is no fluidic connection of the first overall strand to the second overall strand via the valve device 2, so that in the first switching state Z1, the first overall strand is not fluidly connected to the second overall strand via the valve device 2.

In 2 the valve device 2 is in the second switching state designated Z2, so that, for example, the valve device element 5 is in its second switching position. Thus, for example, in the method, the temperature control device 1 is operated in the first switching state Z1 of the valve device 2 and, in particular after or before, in the second switching state Z2 of the valve device 2. In other words, for example, in the method, the temperature control device 1 is operated in such a way that the valve device 2 is in the first switching state Z1 during a first period of time and the valve device 2 is in the second switching state Z2 during a second period of time, the second period of time being, for example, temporal follows the first time period or precedes the first time period. In the second switching state Z2, the first strand 6, the third strand 15 and the second strand 13 are fluidly connected to one another via the valve device 2, that is to say within the valve device 2, and are therefore fluidically connected in series to one another, whereby the first strand 6, the third Strand 15 and the second strand 13 form a third overall strand. In the second switching state Z2, there is no fluidic connection between the third overall strand and the fourth strand 17 via the valve device 2, so that the fourth strand 17 is not fluidly connected to the third overall strand via the valve device 2. In particular, it can be provided that in the second switching state Z2, the pumps 10 and 11 are active or activated at the same time, and therefore run simultaneously, so that, for example, in the second switching state Z2, the temperature control fluid is conveyed simultaneously by means of both pumps 10 and 11. It is conceivable that in the second switching state there is no flow of the temperature control fluid through the fourth line and/or an active delivery of the temperature control fluid through the fourth line. In particular, in the second switching state, the pumps 10 and 11 are connected in series to one another in terms of fluid flow. In the first switching state Z1, for example, the temperature control fluid first flows through the first strand 6 via the connections A2 and A7 from the strand 6 into the fourth strand 17, through the fourth strand 17 and then back into the first via the connections A8 and A1 Strand 6 and then again through the first strand 6, and the temperature control fluid flows, for example, first through the second strand 13 and then via the connections A4 and A6 to and into the third strand 15 and through the strand 15 and then over the Connections A5 and A3 from the strand 15 back to and into the strand 13 and then through the strand 13 again.

As a result, for example, in the second switching state Z2, the temperature control fluid initially flows through the first strand 6 and then via the connections A2 and A6 from the first strand 6 to and into the strand 15 and through the strand 15 and then via the connections A5 and A3 to and into the strand 13 and through the strand 13 and then over the Connections A4 and A1 again to and into the first strand 6 and through the first strand 6, whereby, for example, the temperature control fluid does not flow through the fourth strand 17. In particular, it is conceivable that in the second switching state Z2, the connections A7 and A8 are fluidly separated from each other and also fluidly separated from the remaining connections A1-6.

The temperature control device 1 has a connecting line 22, which is fluidically connected to the fourth strand 17 at a first connection point V1 arranged downstream of the seventh connection A7 and upstream of the ambient air cooler 18 in the fourth strand 17 and at a downstream of the third connection A3 and upstream of the energy storage 14, in particular upstream of the pump 11 and in particular downstream of the chiller, the second connection point V2 is fluidly connected to the second strand 13. The fourth strand 17 has a first length range L1 that extends continuously from the seventh connection A7 to the first connection point V1 and a second length range L2 that extends continuously from the first connection point V1 to the eighth connection A8. The second strand 13 has a third length region L3 which extends continuously from the third connection A3 to the second connection point V2 and in which the chiller is arranged. Furthermore, the second strand 13 has a fourth length region L4 that extends continuously from the second connection point V2 to the fourth connection A4, in which the energy storage 14 and, in the present case, also the pump 11 and the check valve 21 are arranged.

3 shows a possible embodiment of the valve device 2 in a schematic representation.

4 shows the third switching state of the valve device 2, designated Z3. In the third switching state, the second length range L2 is fluidly connected to the first strand 6 via the valve device 2, that is, within the valve device 2, whereby the connecting line 22, the second length range L2 and the first strand 6 are fluidically connected in series with one another and thereby form a fourth overall strand, which is fluidly connected to the third strand 15 via the valve device 2 and thus within the valve device 2, therefore within the valve device housing 4. In the third switching state Z3, the fourth length range L4 is fluidly connected to the third strand 15 via the valve device 2, that is to say within the valve device 2 and within the valve device housing 4, whereby the fourth overall strand and the fourth length range L4 are fluidly parallel to one another and in each case fluidically are connected in series to the third strand 15. The third strand 15 is fluidly connected to the third length range L3 via the valve device 2, that is to say within the valve device 2 and thus within the valve device housing 4, and is thereby connected in series to the third length range L3. A fluidic connection of the first length range L1 with the strands 6, 13, 15 and 17 via the valve device 2 does not occur in the third switching state Z3, and in the third switching state Z3 at least a predominant part of the third length range L3, the connecting line 22 and the fourth length range L4, in particular the entire temperature control fluid flowing through the third length range L3, the connecting line 22 and the fourth length range L4 on its way through the third length range L3, the connecting line 22 and the fourth length range L4, the first length range L1. In particular, it is conceivable that in the third switching state Z3 there is no flow of the temperature control fluid through the first length range L1 and/or an active delivery of the temperature control fluid through the first length range L1. For example, in the third switching state Z3, the temperature control fluid initially flows through the third length range and, for example, from the third connection A3 to the second connection point V2, so that, for example, a first overall flow of the temperature control fluid flows through the third length range L3 and thus from the connection A3 the connection point V2 flows. At the connection point V2, for example, the first total flow, which is also referred to as the first total flow, is divided into a first partial flow and a second partial flow, which in total, for example, result in the first total flow, therefore the first total flow. The first partial flow flows at the connection point V2 into the connecting line 22 and through the connecting line 22 and then into the second length range L2 and through the second length range L2 and to the connection A8 and, for example, the connection A8. The second partial flow flows at the connection point V2 into the fourth length range and through the fourth length range and to the connection A4 and, for example, through the connection A4. The temperature control fluid flowing through the first strand 6 flows from the connection A2 to the connection A6, to which the second partial flow also flows, so that the second partial flow and that The temperature control fluid flowing through the first strand 6 forms a second total flow which flows through the connection A6 and then through the strand 15 and in particular flows from the strand 15 via the connections A5 and A3 to and into the third length range L3 and then the third length range L3 flows through. The first partial flow flows via the connections A8 and A1 to and into the first strand 6 and is therefore the temperature control fluid flowing through the first strand 6.

4 shows the valve device 2 in the fourth switching state designated Z4. In the fourth switching state, the first strand 6 is fluidly connected to the third strand 15 via the valve device 2, and in the fourth switching state Z4, the third strand 15 is fluidly connected to the first length range L1 via the valve device 2, whereby the first strand 6, the third strand 15, the first length range L1, the connecting line 22 and the fourth length range L4 are fluidly connected to one another and are therefore fluidically connected in series to one another and thereby form a fifth overall strand. In the fourth switching state Z4, there is no fluidic connection of the third length range L3 to the strands 6, 13, 15 and 17 via the valve device 2, and in the fourth switching state Z4 there is no fluidic connection of the second length range L2 to the strands 6, 13, 15 and 17 via the valve device 2. In particular, it can be provided that in the fourth switching state Z4, the temperature control fluid does not flow through the third length range L3 and/or the temperature control fluid is actively conveyed through the third length range L3. Alternatively or additionally, it can be provided that in the fourth switching state Z4, the temperature control fluid does not flow through the second length range and/or the temperature control fluid is actively conveyed through the second length range L2.

In the fourth switching state Z4 it is also provided that at least a predominant part of the temperature control fluid flowing through the fifth overall strand, in particular the entire temperature control fluid flowing through the fifth overall strand, passes through the second length range L2 and thereby the second length range L2 arranged in the second length range L2 on its way through the fifth overall strand Ambient air cooler 18 and the third length range L3 and thus bypasses the chiller arranged in the third length range L3.

6 shows a schematic representation of a further possible embodiment of the valve device 2. In particular, for example, 3 and 6 Possible, further, additional or alternative switching states of the valve device 2, in particular switching positions of the valve device element 5, are shown.

7 shows the fifth switching state of the valve device 2, designated Z5. In the fifth switching state Z5, the third strand 15 is fluidly connected to the first length range L1 and to the fourth length range L4 via the valve device 2, that is, within the valve device 2, whereby the first length range L1, the connecting line 22, the fourth length range L4 and the third strand 15 are fluidly connected to one another and are therefore fluidically connected in series to one another and thereby form a sixth overall strand. In particular, it is provided that in the fifth switching state Z5 there is no fluidic connection of the third length range L3 with the strands 6, 13, 15 and 17 via the valve device 2. In addition, in the fifth switching state Z5 it is provided that there is no fluidic connection of the second length range L2 with the strands 6, 13, 15 and 17 via the valve device 2. At least a predominant part of the temperature control fluid flowing through the sixth overall strand, in particular the entire temperature control fluid flowing through the sixth overall strand, bypasses the second length range L2 on its way through the sixth overall strand and thereby the ambient air cooler 18 arranged in the second length range L2 and preferably also the third length range L3 and thus the chiller arranged in the third length range L3, so that, for example, the temperature control fluid does not flow through the length range L2 and/or the temperature control fluid is actively conveyed through the length range L2 and/or so that the temperature control fluid flows through the length range L3 and/or There is no active delivery of the temperature control fluid through the length range L3. In addition, in the fifth switching state Z5 it is provided that there is no fluidic connection between the first strand 6 and the sixth overall strand via the valve device 2. For example, in the fifth switching state the pumps 10 and 11 are activated simultaneously, so that in the fifth switching state Z5 the temperature control fluid is conveyed simultaneously by means of both pumps 10 and 11. In the fourth switching state, the pumps 10 and 11 can be activated simultaneously, so that, for example, in the fourth switching state Z4, the temperature control fluid is conveyed simultaneously by means of both pumps 10 and 11, it being in particular provided that the pumps 10 and 11 are fluidically connected in series to one another . In the third switching state, the pumps 10 and 11 can be activated at the same time, so that in the third switching state Z3 the temperature control fluid is conveyed simultaneously by means of both pumps 10 and 11. For example, the pumps 10 and 11 connected in series to one another in terms of fluid flow.

8th and 9 show in a schematic representation a respective, further possible embodiment of the valve device 2, in particular 8th and 9 further, possible, alternative or additional switching states or switching positions of the valve device 2 or the valve device element 5.

10 shows in a schematic representation a possible sixth switching state of the valve device 2, designated Z6, which can be switched, for example, in particular discretely, into the sixth switching state Z6, in particular by, for example, the valve device element 5, in particular discretely, being relative to a sixth switching position is moved to the valve device housing 4. In the sixth switching state Z6, the first strand 6 and the fourth strand 17 are fluidly connected to one another via the valve device 2, that is to say within the valve device 2 or within the valve device housing 4, and are therefore connected in series to one another, whereby the first strand 6 and the fourth strand 17 form the first overall strand. There is no fluidic connection of the first overall strand with the second strand 13 via the valve device 2, and there is no fluidic connection of the third strand 15 with the second strand 13 via the valve device 2, and there is no fluidic connection between the third strand 15 and the first overall strand via the valve device 2, so that the third strand 15 is not connected to the second strand 13 via the valve device 2 and not to the first overall strand via the valve device 2, and the first overall strand is not connected to the second strand 13 via the valve device 2 tied together. In particular, it is conceivable that in the sixth switching state there is no flow of the temperature control fluid through the third strand 15 and/or an active delivery of the temperature control fluid through the third strand 15. For example, it is provided that in the sixth switching state Z6 both pumps 10 and 11 are activated simultaneously, that is to say run simultaneously, so that, for example, the temperature control fluid is conveyed simultaneously by means of both pumps 10 and 11. Furthermore, the following can be provided in the sixth switching state Z6: The first connection A1 is fluidly connected to the connection A8 within the valve device 2, in particular exclusively in relation to the other connections, and the connection A2 is within the valve device 2, in particular in relation to the others Connections exclusively, fluidly connected to the connection A7, the connection A3 is within the valve device 2, in particular exclusively in relation to the other connections, fluidly connected to the connection A4, the connection A4 is within the valve device 2, in particular exclusively in relation to the other connections , connected to the connection A3, the seventh connection A7 is fluidly connected to the connection A2 within the valve device 2, in particular exclusively in relation to the other connections, and the connection A8 is within the valve device 2, in particular exclusively in relation to the other connections, fluidly connected to the connection A1, while, for example, the connection A5 within the valve device 2 is separated from all other connections and while, for example, the connection A6 within the valve device 2 is separated from the or all other remaining connections. In particular, it is conceivable that in the sixth switching state Z6 there is no flow of the temperature control fluid through the line 15 and/or in the sixth switching state Z6 there is no active delivery of the temperature control fluid through the line 15. Furthermore, it is conceivable that in the sixth switching state Z6 the pumps 10 and 11 are active at the same time and the temperature control fluid is therefore conveyed simultaneously by means of both pumps 10 and 11.

10 shows a schematic representation of the temperature control device 1 with the valve device 2, which is in a seventh switching state Z7, where in 11 Another possible embodiment of the valve device 2 is shown. At the in 11 In the embodiment shown, the valve device 2 has at least or exactly nine connections, namely the connections A1-8 and a ninth connection A9, the first strand 6 also being fluidly connected to the connection A9, therefore connected to the connection A9 and thus also via the Connection A9 is fluidly connected to the valve device 2, in particular to the valve device housing 4.

12 shows schematic representations of further, possible, additional or alternative embodiments of the valve device 2. In particular, go out 12 further, possible, alternative or additional switching states of the valve device 2.

13 shows a further embodiment of the valve device 2 or a further, possible, alternative or additional switching state of the valve device 2. Finally shows 14 a further, possible, alternative or additional switching state of the valve device 2, in particular according to in 11 embodiment shown.

The temperature control device 1 also has an expansion tank 23, in which a quantity 24 of the temperature control fluid is absorbed or receivable. By means of the quantity 24 and by means of the compensation container 23, a volume and/or mass fluctuation of the temperature control fluid in the temperature control circuit 3 can be compensated for. For this purpose, the expansion tank 23 is fluidly connected to the strand 17 and thus fluidly connected to the temperature control circuit 3. Furthermore, a fan 25, designed for example as an electric fan, is assigned to the ambient air cooler 18, by means of which air can be conveyed, the air conveyed by means of the fan 25 being able to flow around or flows around the ambient air cooler 18, thereby flowing through the ambient air cooler 18 via the ambient air cooler 18 To cool the temperature control fluid by means of the air (ambient air) flowing around the ambient air cooler 18.

In 15 until 19 a second embodiment of the temperature control device 1 is illustrated. As explained above, in the first embodiment the valve device 2 has exactly eight ports, namely ports A1, A2, A3, A4, A5, A6, A7 and A8. In contrast, in the second embodiment it is provided that the valve device 2 has exactly seven connections, namely the connections A1, A2, A3, A4, A5, A6 and A7. This is over 15 recognizable.

Another one, for example 15 The noticeable difference between the first embodiment and the second embodiment is that the fourth strand 17, in which the ambient air cooler 18 is arranged, is fluidly connected to the first strand 6 at an opening point M, so that in particular the fourth strand 17 is at the opening point M in the first strand 6 opens. In the flow direction of the temperature control fluid flowing through the strand 6, which is also referred to as the temperature control medium, that is to say in the flow direction of the temperature control fluid flowing through the first strand 6 and flowing from the connection A1 towards the connection A2, the mouth point M is downstream of the connection A1 and upstream of the Connection A2 is arranged in the strand 6, it being provided in particular that the mouth point M is arranged upstream of the branches ZW1, ZW2 and ZW3. At the specific, in 15 In the embodiment shown, the mouth point M is arranged upstream of the pump 10. Thus, in the second embodiment it is provided that the second length range L2 of the fourth strand 17 extends from the first connection point V1, in particular continuously, to the mouth point M. The first strand 6 has a line area LB, which extends from the mouth point M, in particular continuously, to the second connection A2, the branches ZW1, ZW2 and ZW3 as well as the pump 10 being arranged in the line area LB. The temperature control fluid thus flows on its way through the strand 17 and away from the connection A7 towards or in the direction of the valve device 2 through the ambient air cooler 18 and then through or via the mouth point M into the line area LB and then through the line area LB , so that the temperature control fluid flowing through the fourth strand 14 flows via the mouth point M and the line area LB to the connection A2 and flows through the connection A2 and thus flows into the valve device 2, in particular into the valve device housing 4. It can therefore be seen that the fourth strand 7 is fluidly connected to the connection A2 via the mouth point M and the line area LB, that is to say connected to the connection A2 and thus fluidly connected to the valve device 2 via the connection A2, in particular fluidly to the valve device housing 4, is connected. This results in particular in a different integration or connection of the expansion tank 23 compared to the first embodiment, especially since in the second embodiment an advantageous pressure level is given or exists in at least almost every switching position or in at least almost every switching state of the valve device 2.

15 shows a first switching state of the valve device 2 according to the second embodiment. In particular, it is conceivable that the valve device 2 can be switched, in particular discretely, between at least or exactly five switching states, namely the one mentioned above 15 shown, a first switching state, a second switching state, a third switching state, a fourth switching state and a fifth switching state. For example, the second switching state is in 16 , the third switching state in 17 , the fourth switching state in 18 and the fifth switching state in 19 shown. In this regard, it is therefore particularly conceivable that the valve device element 5 can be moved relative to the valve device housing 4, in particular translationally and/or rotationally, between respective switching positions which cause the respective switching states, also referred to as positions, in particular discretely. In particular, the valve device 2 can be switched discretely between the switching states, so that the valve device element 5 can be moved discretely between the switching positions that cause the switching states relative to the valve device housing 4. It is therefore conceivable, for example, that the valve device element 5 can be discretely moved relative to the valve device housing 4 between at least or exactly five switching positions, namely between one of the first switching positions a first switching position that causes the second switching state, a second switching position that causes the second switching state, a third switching position that causes the third switching state, a fourth switching position that causes the fourth switching state and a fifth switching position that causes the fifth switching state. In the respective switching state and thus in the respective switching position, a respective one of the connections A1-7 can be fluidly connected to a respective other one of the connections A1-7 within the valve device 2 and in particular within the valve device housing 4. In particular, the statements regarding the first embodiment also apply to the second embodiment and vice versa.

In 15 The first switching state is now illustrated and designated Z1. In particular, the following can be provided in the first switching state Z1 according to the second embodiment of the temperature control device 1: The first connection A1 is fluidly connected within the valve device 2, in particular exclusively with respect to the other connections, to the third connection and/or to the fifth connection, in particular in such a way that the first connection A1, in particular in relation to the other connections exclusively, receives the temperature control fluid from the third connection A3 and/or from the third connection A5. The second connection A2 is fluidly connected to the seventh connection A7 within the valve device 2, in particular exclusively with respect to the other connections. The third connection A3 is fluidly connected within the valve device 2, in particular exclusively in relation to the other connections, to the first connection A1 and/or to the fifth connection A5, in particular in such a way that, for example, the connection A3 exclusively supplies the temperature control fluid in relation to the other connections from the connection A5 and/or that the connection A3 transfers the temperature control fluid exclusively to the connection A1 in relation to the other connections, in particular within the valve device 2. The fourth connection A7 is within the valve device 2, in particular in relation to the other connections exclusively , fluidly connected to the sixth connection A6. The fifth connection A5 is connected within the valve device 2, in particular exclusively in relation to the other connections, to the connection A3 and/or to the connection A1, in particular in such a way that the connection A5 carries the temperature control fluid within the valve device 2 exclusively in relation to the other connections is transferred to the connection A3 and/or to the connection A1, which means that, for example, the temperature control fluid flowing through the connection A5 and thus flowing into the valve device 2 via the connection A5 within the valve device 2 in relation to the other connections exclusively to and through the connection A3 and/or to and through port A1 flows. The sixth connection A6 is fluidly connected to the fourth connection A4 within the valve device 2, in particular exclusively with respect to the other connections. The seventh connection A7 is fluidly connected to the second connection A2 within the valve device 2, in particular exclusively with respect to the other connections.

Alternatively, it is conceivable that the connection A1 in the first switching state Z1 within the valve device 2 is fluidically separated from all other connections A2-7, so that, for example, the temperature control fluid flowing through the line area LB and subsequently the connection A2 comes from the fourth strand 17 . It can be seen that the first strand 6 in the second embodiment of the temperature control device 1 has the line area LB as the first line area and a second line area LB2, which extends, in particular continuously, from the connection A1 to the mouth point M and, for example, at the mouth point M is fluidly connected to the line area LB. In the first switching state Z1, it is conceivable that the temperature control fluid does not flow from the connection A1 through the line area LB2 to the mouth point M. It is therefore conceivable, for example, that the line area LB and thus the drive machines 7 and 9 are supplied with temperature control fluid exclusively from the length area L2 in relation to the line area LB2 and the length area L2.

16 shows the second switching state Z2 of the valve device 2 according to the second embodiment of the temperature control device 1. In the second switching state Z2, the following can be provided in particular: The first connection A1 is within the valve device 2, in particular with respect to the other connections exclusively, with the connection A5 and /or fluidly connected to the connection A3, in particular in such a way that the connection A1 within the valve device 2 receives the temperature control fluid based on the other connections exclusively from the connection A3 and / or from the connection A5. Furthermore, as in the first embodiment, it is conceivable that the first connection A1 is fluidically separated from the other, remaining connections A2-7, so that, for example, the temperature control fluid does not flow through the second line area LB2 and so that, for example, the line area LB is connected to the temperature control fluid on the line area LB2 and the length area L2 is supplied exclusively from the length area L2. The second connection A2 is within the valve device 2, in particular in relation to the other connections finally fluidly connected to the sixth connection A6, in particular in such a way that the temperature control fluid flowing through the connection A2 within the valve device 2 flows exclusively to and through the sixth connection A6 in relation to the other connections. The third connection A3 is fluidly connected within the valve device 2, in particular in relation to the other connections exclusively, to the connection A5 and/or to the connection A1, in particular in such a way that the connection A3, for example as in the first embodiment, the connection A3 flows through the temperature control fluid in relation to the other connections exclusively from the connection A5, therefore the temperature control fluid flowing through the connection A3 in relation to the other connections comes exclusively from the connection A5 and / or that the temperature control fluid flowing through the connection A3 within the valve device 2 exclusively the connection A1 flows through, that is, it is exclusively transferred to connection A1. The fourth connection A4 is fluidly connected to the connection A6 within the valve device 2, in particular exclusively in relation to the other connections, in particular in such a way that the connection A4 transfers the temperature control fluid within the valve device 2 exclusively to the connection A6 in relation to the other connections, This means that the temperature control fluid flowing through connection A4 within the valve device 2 flows exclusively through connection A6 in relation to the other connections.
The fifth connection A5 is fluidly connected within the valve device 2, in particular in relation to the other connections exclusively, to the connection A3 and/or to the connection A1, in particular in such a way that the connection A5 relates the temperature control fluid flowing through the connection A5 within the valve device 2 to the other connections exclusively to the connection A3 and / or to the connection A1, meaning that the temperature control fluid flowing through the connection A5 within the valve device 2 flows exclusively through the connection A3 and / or the connection A1. The sixth connection A6 is fluidly connected within the valve device 2, in particular exclusively in relation to the other connections, to the connections A2 and A4, in particular in such a way that the temperature control fluid flowing through the connection A6 comes exclusively from the connections A2 and A4 in relation to the other connections , meaning that the temperature control fluid within the valve device 2 flows, based on the connections, exclusively from the connections A2 and A4 to and through the connection A6. In particular, it is provided that the seventh connection A7 within the valve device 2 is separated from the or all other remaining connections. Thus, for example, the temperature control fluid flows from the connection A3 through the length area L3 and then through the connecting line 22 and through the length area L2 to the mouth point M and from the mouth point M through the line area LB, so that, for example, a flow of the temperature control fluid through the length area L1 and in particular from the connection A7 to the connection point V1 is omitted.

17 shows the third switching state Z3 of the valve device 2 according to the second embodiment of the temperature control device 1. In the third switching state Z3, for example, the following is provided: The first connection A1 is fluidly connected to the connection A4 within the valve device 2, in particular exclusively with respect to the other connections , the second connection A2 is fluidly connected to the connection A6 within the valve device 2, in particular exclusively in relation to the other connections, the third connection A3 is fluidly connected to the connection A1 within the valve device 2, in particular exclusively in relation to the other connections , the connection A5 is fluidly connected to the connection A3 within the valve device 2, in particular exclusively in relation to the other connections, and the connection A6 is fluidly connected to the connection A2 within the valve device 2, in particular exclusively in relation to the other connections, while, for example, the connection A7 within the valve device 2 is separated from the or all other remaining connections. In particular, in the third switching state Z3 it is provided that there is no flow of the temperature control fluid through the first length range L1 and through the length range L2 and thus through the ambient air cooler 18, and for example there is also no flow of the temperature control fluid through the connecting line 22, in particular from the Connection point V2 to the connection point V1. Thus, for example, in the third switching state Z3 it is provided that the line area LB is supplied with the temperature control fluid exclusively from the line area LB2 in relation to the line area LB2 and the length area L2.

18 shows the fourth switching state Z4 of the valve device 2 according to the second embodiment of the temperature control device 1. In particular, the following can be provided in the fourth switching state Z4: The connection A1 is fluidly connected to the connection A4 within the valve device 2, in particular exclusively with respect to the other connections , the connection A2 is fluidically connected to the connection A6 within the valve device 2, in particular with regard to the other connections exclusively den, the connection A4 is fluidically connected to the connection A1 within the valve device 2, in particular exclusively in relation to the other connections, the connection A5 is fluidly connected to the connection A7 within the valve device 2, in particular exclusively in relation to the other connections, the connection A6 is fluidly connected to the connection A2 within the valve device 2, in particular exclusively in relation to the other connections, and the connection A7 is fluidly connected to the other connection A5 within the valve device 2, in particular exclusively in relation to the other connections, in particular while the connection A3 within the valve device 2 is fluidically separated from the or all other remaining connections. Thus, for example, there is no flow of the temperature control fluid through the length range L3, and there is no flow of the temperature control fluid through the length range L2 and thus through the ambient air cooler 18, so that, for example, the temperature control fluid from the seventh connection A7 through the length range L1 and then through the connecting line 22 and then flows through the length range L4. Thus, for example, the line area LB is supplied with the temperature control fluid exclusively from the line area LB2 in relation to the line area LB2 and the length area L2.

Finally shows 19 the fifth switching state Z5 of the valve device 2 according to the second embodiment of the temperature control device 1.

Thus, for example, in the fifth switching state Z5, there is no flow of the temperature control fluid through the length range L3 and through the length range L2 and thus through the ambient air cooler 18, so that, for example, the temperature control fluid flows from the connection A7 through the length range L1 and then through the connecting line 22 and then through the Length range L4 and finally flows through connection A4. Thus, for example, in the fifth switching state Z5 it is provided that the line area LB is supplied with the temperature control fluid exclusively from the line area LB2 in relation to the line area LB2 and the length area L2. As already described above, in the first switching state Z1 and/or in the second switching state Z2 it can be provided that the connection A1 within the valve device 2 is separated from all other, remaining connections.
