Изобретение относитс : к вспомогательному оборудованию судовых энергетических установок и может быть использовано преимущественно в машинострое-гThe invention relates to: auxiliary equipment of ship power plants and can be used mainly in the machine building industry

НИИ.SRI.

Известны устройства дл охлаждени электродвигателей судовых установок , содержащие пучок вертикальных сребренных труб, установленных между нижним и верхним бачками, верхн и нижн стенки которых, соотвественно служат трубными решетками оребренных труб, и верхн из них снабжена желобом, причем верхний бачок выполнен в .виде кожухотрубного теплообменника с раздагошим и собирающим коллекторами l .There are known devices for cooling electric motors of ship installations, containing a bundle of vertical silver pipes installed between the lower and upper tanks, the upper and lower walls of which serve as tubular grids of finned pipes, respectively, and the upper one is provided with a chute, and the upper tank is made in the form of a shell-and-tube heat exchanger with razdagoshim and collecting headers l.

Недостатки известных устройств заключаютс в их нетехнологичности, а именно в невозможности осутцеств-чени периодической очистки конструктннн1 1х элементов и узлов без оттитючени устройства из работы на длительный период.The disadvantages of the known devices are their inconvenience, namely, the impossibility of osuschestven-tion of periodic cleaning of constructive elements and nodes without removing the device from work for a long period.

а также в трудоемкости монтажно-демонтажных работ.as well as in the complexity of installation and dismantling.

Цель изобретени - повышение технологичности .The purpose of the invention is to improve manufacturability.

Цель достигаст :: тем, что коллекторы размещены с одного торца верхнего бачка , а жолоб подключен к первому р ду труб пучка со стороны его другого торца , при этом над верхней трубной решеткой размещена продольна профильна The goal will be achieved :: by the fact that the collectors are located at one end of the upper tank, and the chute is connected to the first row of beam pipes from its other end, while a longitudinal profile is placed above the upper tube sheet

10 перегородка, расположенна с наклоном, в,сторону желоба и прикрепленна к коллекторам . 10 partition, located with a slope in the side of the gutter and attached to the collectors.

На фиг. 1 изображено устройство, продольный разрез; на фиг. 2 - разрез FIG. 1 shows a device, a longitudinal section; in fig. 2 - section

Claims

The device contains pipes 1 with ribs 2, lower tank 3, upper tank 4, tube sheets 5 and 6, chute 7, shell-and-tube heat exchanger 8 with collectors 9 and 1 O, longitudinal profile partition 11, lid 12 and pipes 13. The heat exchanger 8 is equipped with a valve for purging and venting, with a meter 15, a safety valve 16, and a tank 3 with a tap 17 for supplying the coolant to the pipes 2 and removing the coolant from them. The device works as follows. The hot air of the gas turbine supercharging of the ship’s engine or the opening of a closed system. The cooling of the rowing electric machines enters the pipes 1. Hot air temperature 70-1О5 С Intermediate heat carrier, for example, F-.21, F-14, and others) boils at a design temperature of about 25 -35 ° C. Air at 4 oh oh, chla) 1 is allowed to reach about 40 ° C. The intermediate heat carrier vapors rise into the upper tank 4 - shell-and-tube heat exchanger 8, where they condense on the pipes 13. The tubes of the battery are inclined (tilt angle 10-15) that provides condensate drain This also increases heat transfer by 4 ° -5%. Condensate is scooped in chute 7, from where it flows into tank 3, outboard water is supplied to pipes 13. At steady state, the pressure in the apparatus, and hence the boiling point, is regulated by the amount of cooling water. In the described device, the countercurrent of steam and condensate is removed, i.e. contact of steam and covdensate, significantly reduced scale formation on pipes and facilitated installation and dismantling works, due to the presence of collapsible elements, which, in turn, increases the coefficient of working time of the device. When using the device as an air cooler for cooling the rowing electric machines, seawater and salt are also prevented from entering the collector, brushes and windings of these machines., Invention A device for cooling power equipment, mainly ship installations, containing a bundle of vertical finned tubes installed between the lower and upper horizontal tanks, the top and bottom walls of which, respectively, serve as tube grids of finned tubes, and the top of the shch is equipped with a chute, and The tank is made in the form of a shell-and-tube heat exchanger, with a distributing and collecting collectors, so that, in order to improve manufacturability, the collectors are placed from one end of the upper tank, and the trough is connected to the Nerve row of pipes a bundle with CTOjpoHbi of its other end; in this case, a longitudinal profile partition is placed above the upper tube sheet, located with a slope In the direction of the channel and attached to the collectors.
