Coolant cooled type semiconductor device

摘要

A coolant cooled type semiconductor device capable of achieving a superior heat radiation capability is provided, while having a simple structure. While a plurality of semiconductor modules 1 are arranged in such a manner that main surface directions of these semiconductor modules 1 are positioned in parallel to each other in a interval along a thickness direction thereof. These semiconductor modules 1 are sandwiched by coolant tube 2 having folded portions with fixing members 6, 7, 10. As a consequence, both surfaces of the semiconductor module 1 can be cooled by a single coolant tube with a uniform pinching force.
