Abstract
A heat sink for a power module able to realize a further improvement of heat radiating performance and a further improvement of a mounting property is provided. The heat sinkfor a power module has a laminating body, a first side plateand a second side plate. The laminating bodyhas plural flow path platesformed in a plate shape in which plural groovesparallel to each other are concavely arranged on a flat joining face. Each grooveis set to a parallel flow pathparallel to a front face side by laminating each flow path plateby each joining face. A portion other than each grooveof each joining faceforms a heat transfer pathto each parallel flow pathof a laminating direction. A flow-in pathand a flow-out pathare formed in the first and second side plates. The flow-in pathand the flow-out pathare joined to side facesof the laminating body, and are communicated with each parallel flow path. The flow-in pathflows a cooling medium into each parallel flow path. The flow-out pathflows the cooling medium out of each parallel flow path. A refrigerant flow path is constructed by the flow-in path, each parallel flow pathand the flow-out path
