Title:
電力変換装置及び鉄道車両
Document Type and Number:
Japanese Patent JP7132091
Kind Code:
B2
Abstract:
To provide a power converter capable of securing desired cooling performance and strength while supplying traveling wind to a circulation path between a plurality of fins effectively.SOLUTION: The power converter includes a semiconductor element, a heat receiving block, a plurality of fins, and a wind receiving member. The semiconductor element can output power for driving a vehicle. The heat receiving block is mounted with the semiconductor element. The plurality of fins are provided on the heat receiving block and arranged with a predetermined gap in a direction orthogonal to an assumed traveling direction of the vehicle. The wind receiving member includes a pair of base parts respectively joined to a lower surface of both ends of the plurality of fins in the assumed traveling direction and a pair of flange parts extending below the plurality of fins from each of the pair of base parts to receive the traveling wind of the vehicle.SELECTED DRAWING: Figure 2
