To provide a power conversion device for a railway vehicle which suppresses cooling function degrading of a heat radiation part caused by a foreign object adhesion and a contamination.SOLUTION: A power conversion device 100 comprises: a power conversion unit 1 (2) which includes a power conversion part body 1a (2a) and a heat radiation part 1b (2a) for dissipating a heat in the power conversion part body 1a (2a); a unit fitting frame 3 to receive the power conversion unit 1 (2); and a sealed housing 10 which is installed in a railway vehicle 101 and stores the unit fitting frame 3 internally. The device is constituted to store the heat radiation part 1b (2a) in the sealed housing 10 by means of storing, in the housing 10, the unit fitting frame 3 in which the power conversion unit 1 (2) that includes a heat radiation part 1b (2a) is stored.SELECTED DRAWING: Figure 5

    【課題】異物付着および汚損による放熱部の冷却機能の低下を抑制可能な鉄道車両用電力変換装置を提供する。【解決手段】電力変換装置100は、電力変換部本体1a(2a)と電力変換部本体1a(2a)の内部の熱を放熱するための放熱部1b(2a)とを含む電力変換ユニット1(2)と、電力変換ユニット1(2)を収容するユニット取付フレーム3と、鉄道車両101に設けられ、ユニット取付フレーム3を内部に収納する密閉された筐体10と、を備える。そして、放熱部1b(2a)を含む電力変換ユニット1(2)が収容されたユニット取付フレーム3を筐体10内に収納することにより、放熱部1b(2a)を密閉された筐体10内に収納可能に構成されている。【選択図】図5
