たのである。 However, in the above structure, since the heat exchanger B acts as a ventilation resistor, the outside air intake port E
The amount of air that is taken in from the heat exchanger B and passes through the heat exchanger B is reduced accordingly, making it difficult to sufficiently cool the electrical component C.
It was also impossible to arbitrarily adjust the amount of air acting on the air.

In addition to installing electrical components inside, the dividing plate is provided with an air intake port that opens to the air inflow side of the heat exchange chamber, and an air discharge port that opens to the air outflow side of the heat exchange chamber. A part of the outside air taken in is bypassed to the air chamber to cool the electrical components.
