SEMICONDUCTOR MODULE AND COOLING UNIT

摘要

A semiconductor module including a cooling unit by which a fine cooling effect is obtained is provided. A plurality of cooling flow paths (21c) which communicate with both of a refrigerant introduction flow path which extends from a refrigerant introduction inlet and a refrigerant discharge flow path which extends to a refrigerant discharge outlet are arranged in parallel with one another in a cooling unit (20). Fins (22) are arranged in each cooling flow path (21c). Semiconductor elements (32) and (33) are arranged over the cooling unit (20) so that the semiconductor elements (32) and (33) are thermally connected to the fins (22). By doing so, a semiconductor module (10) is formed. Heat generated by the semiconductor elements (32) and (33) is conducted to the fins (22) arranged in each cooling flow path (21c) and is removed by a refrigerant which flows along each cooling flow path (21c).
