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. | 2014-05-22 |
