Description

  The present invention relates to an outdoor unit of a separation type air conditioner having an end plate at an end portion of a heat exchanger.

The conventional outdoor unit of the separation type air conditioner is configured by integrally forming a metal end plate provided at both ends of the fin in addition to the U-shaped copper tube and the fin, and the metal end plate as an outer box bottom plate. Or there existed what was comprised by screwing to the outer box side board (for example, refer patent document 1).
Further, the heat exchanger is composed of one or a plurality of rows depending on the heat exchange capability required by the air conditioner, and is often installed by bending into an L shape or a U shape. When the heat exchanger is composed of a plurality of rows, the length of the outer row and the inner row of the heat exchanger is different. Therefore, the end plate on the closed side of the U-shaped copper tube is installed separately in the outer row and the inner row. Resin the U-shaped copper tube in the outer row and the U-shaped copper tube in the inner row after the end plate is installed only in the outer row and bent into the L shape or U shape after being bent into the U shape In some cases, the band was bound together.
7 is a perspective plan view in which a part of the outdoor unit of the conventional separation type air conditioner described in Patent Document 1 is omitted, and FIG. 8 is a part of the outdoor unit of the conventional separation type air conditioner. FIG.

7 and 8, the outdoor unit 1 is provided with an outer box bottom plate 2, an outer box left side plate 3, an outer box right side plate 4, an outer box front plate 5, and an outer box top plate (not shown) on the exterior. In addition, a partition plate 6, a blower 7, and a compressor 8 are installed therein, and an L-shaped heat exchanger 10 sandwiched between end plates 9a, 9b, and 9c is attached to the rear and left sides of the outer box bottom plate 2 with screws 11 It was fixed and constituted by. The heat exchanger 10 has U-shaped copper tubes 10a and 10b and fins 10c and 10d.
With this configuration, the outdoor unit fixed the internal heat exchanger, and was able to hold the heat exchanger without being damaged during transportation or air conditioning operation.
