To provide an electric power conversion device for a railway vehicle which suppresses not only deterioration of components in an air duct part but also degradation of cooling characteristics of the air duct part caused by intrusion of foreign materials and moisture into the air duct part.SOLUTION: In the electric power conversion device for the railway vehicle, an air inlet 24 for supplying air from the outside of an air duct part 40 into the inside of the air duct part 40, and an air outlet 25 for exhausting air, which is supplied from the air inlet 24 into the inside of the air duct part 40 and is used to cool an inverter circuit part 31a through an inverter heat radiation part 31b, to the outside the air duct part 40, are arranged on side faces 21b on the same side of a housing 21.SELECTED DRAWING: Figure 3

    【課題】異物および水分が風洞部の内部に侵入することに起因して風洞部内部の部品が劣化するのを抑制するとともに風洞部の冷却性能が低下するのを抑制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】この鉄道車両用電力変換装置では、風洞部40の外部から風洞部40の内部へ空気を給気するための給気口24、および、給気口24により風洞部40の内部へ給気されインバータ放熱部31bを介してインバータ回路部31aを冷却した空気を風洞部40の外部へ排気するため排気口25を、筐体21の同じ側の側面21bに配置する。【選択図】図3
