PROBLEM TO BE SOLVED: To efficiently cool a power semiconductor of a power conversion device.SOLUTION: A power conversion device comprises a plurality of power semiconductor elements, a heat receiving member and a plurality of plate-like heat radiation fins. The plurality of power semiconductor elements are attached to one side surface in the horizontal direction of the heat receiving member. The plurality of heat radiation fins are provided on the other side surface in the horizontal direction of the heat receiving member and include air blowers of generating cooling air to be introduced into the plurality of heat radiation fins. The power conversion device is mounted under the floor of a railroad vehicle and configured so that the plate surface of the plurality of heat radiation fins faces the travel direction of the vehicle.SELECTED DRAWING: Figure 1

    【課題】電力変換装置のパワー半導体を効率的に冷却する。【解決手段】複数のパワー半導体素子と、受熱部材と、複数の板状の放熱フィンとを備え、複数のパワー半導体素子は受熱部材の水平方向の一方側の面に取付けられ、複数の放熱フィンは受熱部材の水平方向の他方側の面に設けられ、複数の放熱フィンに導入される冷却風を発生させる送風機を備え、鉄道車両の床下に搭載される電力変換装置であって、複数の放熱フィンの板面が車両の進行方向を向くように構成する構造とした。【選択図】 図1
