Claims

[Scope of utility model registration request]

In a cooling structure for removing heat generated from electrical equipment in a power distribution board that stores electrical equipment in a sealed case, a cooling structure is formed on both sides of a partition plate that is installed in the case with one end separated from the lower end surface of the case, Heat should be exchanged between the outgoing chamber where the air inside the panel flows along the partition plate, the return chamber where the air in the panel communicates with this outgoing chamber at the lower end of the partition plate, and where the air inside the panel flows in the opposite direction to the outgoing chamber, and the upper part of this return chamber. The inlet of air inside the panel is
On the other hand, it consists of a heat exchanger with an outlet for the heat-exchanged air inside the panel opened to the outside of the case in the upper part of the outgoing chamber, and a blower that circulates the air inside the panel between the outgoing chamber, the return chamber, and the heat exchanger. A cooling structure for a power distribution board characterized by:
