Semiconductor module and cooling unit
First Claim
1. A semiconductor module comprising:
- a cooling unit including;
a first flow path which extends from a refrigerant introduction inlet, a second flow path which is arranged in parallel with the first flow path and which extends to a refrigerant discharge outlet, a plurality of third flow paths which communicate with the first flow path and the second flow path, a heat sink which is arranged in the plurality of third flow paths, and one or more guides for guiding a refrigerant in the direction of extending the first flow path in the first flow path, wherein the one or more guides are separated from an edge of the plurality of third flow paths; and
at least one semiconductor element which is thermally connected to the cooling unit.

Abstract
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).
