Title:
車両用電力変換装置
Document Type and Number:
Japanese Patent JP5889479
Kind Code:
B2
Abstract:
Semiconductor elements work for power conversion and generate heat. A plurality of heat-radiating fins are juxtaposed at intervals to form a passage in a first axis direction, receive the heat from the semiconductor elements, and expel the heat into the air flowing through the passage. A first protective fin has an end face having an equal length in the juxtaposition direction to and mutually facing the end face on the first axis positive side of at least some of the heat-radiating fins, and extends in the first axis positive direction from that end face. A second protective fin has an end face having an equal length in the juxtaposition direction to and mutually facing the end face on the first axis negative side of at least some of the heat-radiating fins, and extends in the first axis negative direction from that end face.
