る。C. Effects of the Invention] As described above, according to the present invention, since the heat exchange capacity is built-in, it can be incorporated into the control panel without interfering with the equipment inside the panel, and by removing the heat exchanger, the corrugated It is easy to clean the outside air rectangular flow path in the heat exchanger plate, and especially in the case of the second embodiment, the entire lower end surface of the heat exchanger plate is covered with a packing installed on the entire inner bottom surface of the heat exchanger case. It can be airtightly sealed, and each partition wall of the heat exchanger plate can be positioned and fixed by using the rectangular cross-section packing, which has the effect of greatly reducing the number of assembly steps.
