摘要： A power module includes a power device and a heat sink. The heat sink includes a refrigerant passage in which a cooling medium flows and a corrugated fin body arranged in the refrigerant passage. The refrigerant passage is defined by a surface and a backside, and the power device is disposed in proximity to the surface. The corrugated fin body has crests and troughs that extend in the flow direction of the cooling medium and side walls each of which connects the corresponding one of the crests with the adjacent one of the troughs. Each adjacent pair of the side walls and the corresponding one of the crests or the corresponding one of the troughs arranged between the adjacent side walls form a fin. A guide that extends in the flow direction of the cooling medium and operates to stir the cooling medium is arranged in each of the fins.

摘要： A heat sink (1) for power module is capable of mounting a power device (101) on at least a surface of the heat sink. The heat sink includes a refrigerant passage (1d) in which cooling medium that dissipates heat generated by the power device (101) flows and a corrugated fin body (1a) arranged in the refrigerant passage (1d). The corrugated fin body (1a) has crests (21b) and troughs (21c) that extend in the flow direction of the cooling medium, and side walls (21a) each of which connects the corresponding one of the crests (21b) with the adjacent one of the troughs (21c). Each adjacent pair of the side walls (21a) and the corresponding one of the crests (21b) or the corresponding one of the troughs (21c) arranged between the adjacent side walls (21a) form a fin (21). Each of the side walls (21a) has a louver (31) that operates to, at least, rotate the cooling medium flowing in the associated fin (21). The heat sink (1) thus has a further improved heat dissipating performance.

The laminating body 20 has plural flow path plates 21 formed in a plate shape in which plural grooves 23 parallel to each other are concavely arranged on a flat joining face 22. Each groove 23 is set to a parallel flow path 50 parallel to a front face side by laminating each flow path plate 21 by each joining face 22. A portion other than each groove 23 of each joining face 22 forms a heat transfer path 70a to each parallel flow path 50 of a laminating direction. A flow-in path 30a and a flow-out path 40a are formed in the first and second side plates 30, 40. The flow-in path 30a and the flow-out path 40a are joined to side faces 26a, 26b of the laminating body 20, and are communicated with each parallel flow path 50. The flow-in path 30a flows a cooling medium into each parallel flow path 50. The flow-out path 40a flows the cooling medium out of each parallel flow path 50. A refrigerant flow path is constructed by the flow-in path 30a, each parallel flow path 50 and the flow-out path 40a.
