To provide an electric power conversion device which can secure desirable cooling performance by effectively supplying traveling wind to a wind receiving part, and a railway vehicle.SOLUTION: An electric power conversion device comprises semiconductor elements, a wind receiving part, air guides, wind regulating parts and flange parts. When an assumed running direction of a vehicle is defined as a first direction, a gravity direction is defined as a second direction, and a direction orthogonal to the first direction and the second direction is defined as a third direction, the air guides are arranged to oppose each other in the third direction with respect to the wind receiving part, and an end part close to the center of the wind receiving part out of both ends in the first direction is set as a first end part, and an end part on the opposite side of the first end part is set as a second end part. The wind regulating parts extend along the first direction from the first end part of the air guides and toward the opposite side of the second end part. The flange parts extend toward the opposite side of the wind receiving part side from the second end part of the air guides.SELECTED DRAWING: Figure 3

    【課題】受風部に対して走行風を効果的に供給し、所望の冷却性能を確保できる電力変換装置及び鉄道車両を提供することである。【解決手段】実施形態の電力変換装置は、半導体素子と、受風部と、導風ガイドと、整風部と、鍔部と、を持つ。導風ガイドは、車両の走行想定方向を第1方向とし、重力方向を第2方向とし、これら第1方向及び第2方向に直交する方向を第3方向としたとき、受風部に対して第3方向で対向配置されるとともに、第1方向の両端部のうち、受風部の中央部寄りの端部を第1端部とし、第1端部とは反対側の端部を第2端部とする。整風部は、導風ガイドの第1端部から第1方向に沿って、且つ第2端部とは反対側に向けて延びる。鍔部は、導風ガイドの第2端部から受風部側とは反対側に向けて延びる。【選択図】図3
