Refrigerant cooling type double-sided cooling semiconductor device

摘要

PPROBLEM TO BE SOLVED: To provide a coolant cooling type both sides cooling semiconductor device with simple structure and excellent heat dissipation capability. PSOLUTION: In the semiconductor device, while a both sides cooling type semiconductor module 1 and a coolant tube 2 with a flat contacting heat-receiving surface and with cooling fluid flowing inside, are closely contacted with an insulating spacer in between, both sides cooling type semiconductor module 1 is sandwiched and pressed with sandwiching and pressing members 6, 7, 10, between the coolant tubes 2, in a thickness direction of both sides cooling type semiconductor module 1, thereby simplifying structure, increasing cooling effect, and reducing irregularities of cooling effect.
