To provide a power conversion device for a railway vehicle capable of making traveling wind easily flow into a cooling fin arranged in a recessed part of a housing for the power conversion device.SOLUTION: A power conversion device 100 includes: a housing 10, which is mounted on a lower part 101b of a railway vehicle main body 101a, storing a power conversion part 1 in its inside, and provided with a recessed part 2 recessed inward; and a plurality of plate-like cooling fins 3, which are provided in the recessed part 2 so as to extend along a traveling direction (a direction of the flow of cooling air) of a railway vehicle main body 101a with intervals, and cool the power conversion part 1 by the traveling wind of the railway vehicle main body 101a. The power conversion device 100 includes a protrusion part 4 which is provided on an upstream side of the traveling wind of the cooling fins 3 on a surface 21a of the housing 10 in the vicinity of the recessed part 2 and protrudes toward the side opposite to the recessed direction of the recessed part 2.SELECTED DRAWING: Figure 2

    【課題】電力変換装置用筐体の凹状部に配置される冷却フィンに走行風を流入させやすくすることが可能な鉄道車両用電力変換装置を提供する。【解決手段】この電力変換装置100は、鉄道車両本体101aの下部101bに取り付けられるとともに内部に電力変換部1を収容し、内側に窪む凹状部2が設けられている筐体10と、凹状部2に、鉄道車両本体101aの走行方向(冷却風の流れ方向)に沿って延びるとともに互いに間隔を隔てて配置され、鉄道車両本体101aの走行風により電力変換部1を冷却する複数の板状の冷却フィン3と、を備える。また、電力変換装置100は、凹状部2近傍の筐体10の表面21aで、かつ、冷却フィン3の走行風の上流側に設けられ、凹状部2が窪む方向とは反対側に突出する突起部4を備える。【選択図】図2
