ータ装置。 A mounting plate with cooling fins protruding downward is provided in the center of the box, and a space between the mounting plate and the bottom plate of the box serves as a ventilation path for cooling air.
In the forced cooling type inverter device, in which a semiconductor element is disposed on the mounting plate, and the heat generated by the semiconductor element is radiated through the cooling fin, the cooling fin protrudes into the ventilation path on the upper surface of the bottom plate of the box body. A forced cooling inverter device characterized by providing turbulent fluid.
