PROBLEM TO BE SOLVED: To prevent a heat influence from waste-heat from an underfloor device having a high-temperature exhaust gas among multiple underfloor devices provided under the floor.SOLUTION: A power generation unit 210 comprising a diesel generator 211 and a generator radiator 212, a power converter 220, and other underfloor devices 240 are mounted under the floor of a vehicle body 100 of a railway vehicle. A heat barrier member 221 is provided at least in a bottom surface of the power converter 220 to suppress a rise in temperature due to high-temperature exhaust gas flowing toward a rail track surface from the generator radiator 212.

    【課題】床下に設置される複数の床下機器間で、高温の排気を伴う床下機器からの排熱による熱の影響を防ぐ。【解決手段】鉄道車両の車体100の床下には、ディーゼル発電機211と発電機用放熱器212とからなる発電ユニット210、電力変換器220、その他の床下機器240が搭載されている。発電機用放熱器212から線路面に向けて流れる高温の排気による温度上昇を抑制するため、少なくとも電力変換器220の底面に遮熱部材221を設けた。【選択図】図2
