電気部品の放熱が行なわれる。If the electrical components of the outdoor unit generate heat and reach high temperatures while the air conditioner is operating, these electrical components may deteriorate or malfunction, so it is necessary to constantly dissipate heat to lower the temperature. During heat dissipation, the heat dissipation fins (11) come into contact with the air in the machine room (5) and are cooled by heat exchange. 8) is cooled by heat transfer, and further the electrical components inside the electrical component box (8) are cooled. The heat dissipation fins (11) are made of aluminum with high thermal conductivity, and the fin shape has a large contact area with the air, so the heat exchange efficiency with the air is high. As a result, heat is radiated from electrical components such as semiconductor elements that perform inverter control.

招くこととなった。[Problems to be Solved by the Invention] Since the outdoor unit of the conventional air conditioner is configured as described above, the air that cools the radiation fins (11) remains in the machine room (5) and the outside air There is almost no distribution. In addition to the heat released from the heat dissipation fins (11), the heat from the compressor (7), which becomes hot during operation, is also released from the machine room (
5), the temperature of the air in the machine room (6), especially in the upper part where the electrical box (8) is attached, naturally increases. As a result, the heat dissipation fins (11) were not able to efficiently dissipate heat, resulting in deterioration and failure of electrical components.
この不具合を解消するために、例えば、前記実開昭６０
