Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing an outdoor unit of an air conditioner according to the present invention, and FIG. 2 (A) is a cross-sectional view from above, and FIG.
(B) is a perspective view of a main part. 3 (A) to FIG.
(C) is a perspective view showing another embodiment. As shown in FIG. 1, an outdoor unit of an air conditioner according to the present invention has an L-shape on a base plate 1 formed in a substantially rectangular shape so as to extend from both left and right sides of the base plate 1 to the back side. The folded and juxtaposed fins and a pair of heat exchangers 6 having heat transfer tubes arranged in a meandering manner so as to be orthogonal to the fins are placed so as to face each other. Provided. A fan motor 11 for driving a blower fan 10 is provided at a front portion of the base plate 1.
A mounting base 9 supporting the air blower 1 is provided.
A fan ring 4 is provided so as to cover 1. Around the compressor 5, a cylindrical partition plate 7 having an open rear is provided so as to cover the compressor 5. At the rear open end of the partition plate 7, a fixing portion 7a having a plurality of screw holes 7b formed vertically is provided.
As shown in (A), the heat exchanger 6 is fixed to a front edge of a side plate 6a provided at one end side by a screw 40. An electrical component box 12 having a control board and the like is arranged between the pair of heat exchangers 6. After these devices are mounted, the base plate 1 is made of sheet metal, the front and bottom surfaces of which are opened, and the suction port 2
The outer shell 2 formed with a is mounted, and on the opened front surface, a blowout grill 3 formed of a resin material and formed with a blowout port 3a is mounted.

FIG. 2 shows the side plate 6a on the partition plate 7 side.
As shown in (B), the heat radiation holes 6b are perforated in two rows and multiple stages. The heat radiating holes 6b are formed in the same shape as the insertion holes through which the heat transfer tubes are inserted. When the heat exchangers are provided in two rows, the heat transfer tubes are inserted into one row of the heat radiating holes 6b, and The U-shaped tube 6c is attached by welding.

Next, the operation of the heat radiating hole 6b will be described. The air sucked in from the suction port 2a undergoes heat exchange by the heat exchanger 6, and is sent out from the outlet 3a of the outlet grill 3 toward the front by the blower fan 10. At this time, the heat generated from the compressor 5 is transmitted from the heat exchanger 6 through the heat radiation holes 6b formed in the side plate 6a.
Is sucked by the flow of air passing through the
From the aircraft. This allows
Even if it is covered with the partition plate 7, the compressor 5 can be prevented from being heated, and the noise generated from the compressor 5 can be minimized from leaking to the outside.

Next, another embodiment will be described. FIG.
(A) shows a side plate 14 attached to the heat exchanger 6, and the side plate 14 has a heat radiating portion 14a in which a plurality of heat radiating holes 14b are perforated and is expanded toward the front. Thereby, the air that has passed through the heat exchanger 6 flows along the heat radiating portion 14a, and the heat released from the heat radiating holes 14b is easily sucked, so that the heat radiating effect is enhanced.

Further, as shown in FIG.
A plurality of notches 15a for intake are provided at the lower end edge of 5, and cooling air is sucked from the notches 15a to enhance the cooling effect of the compressor 5.

In the example shown in FIG. 3C, a rectangular heat radiating hole is provided in the side plate 16 by the cut-and-raised portion 16a, and turbulence is induced in the air by the cut-and-raised portion 16a to enhance the heat radiation effect. I have.

As described above, according to the present invention,
By piercing a plurality of heat radiating holes on a partition plate side of a side plate provided at one end of a heat exchanger disposed on a base plate opposed to each other, heat generated from a compressor is transmitted by the heat radiating holes. The air conditioner can be an outdoor unit that can be discharged to the outside to prevent the compressor from being heated.
