Abstract
A power converter including: a plurality of semiconductor devices forming a power conversion circuit; a base section to which the plurality of semiconductor devices are attached; and radiating fins dissipating heat generated from the semiconductor devices into outside air, in the power converter in which the direction of the flow of a refrigerant flowing into the radiating fins changes depending on the operation status of the power conversion circuit, the shape of each radiating fin changes in such a way that the cross-sectional area of a channel of the refrigerant on the outflow side becomes smaller than the cross-sectional area of the channel of the refrigerant on the inflow side in the radiating fins depending on the direction of the flow of the refrigerant.
