Abstract
A power conversion device such that heat dissipation can be improved is obtained. The power conversion device includes a power conversion circuit unit that converts direct current into alternating current using a semiconductor switching element, a heatsink on which the power conversion circuit unit is mounted, and which has a first passage through which a cooling medium is caused to pass, and a frame body that houses the power conversion circuit unit, seals the power conversion circuit unit between the frame body and the heatsink, and has a second passage through which a cooling medium is caused to pass, wherein the first passage and second passage are connected at an interface between the heatsink and frame body, thereby configuring a cooling passage.
