    • 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 sink 1 for a power module has a laminating body 20, a first side plate 30 and a second side plate 40. 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.
    • 提供了能够实现进一步提高散热性能的功率模块的散热器,并且进一步提高了安装特性。 用于功率模块的散热器1具有层叠体20,第一侧板30和第二侧板40.层叠体20具有多个形成为板状的流路板21,多个相互平行的槽23 凹陷地布置在平坦的接合面22上。每个槽23通过每个接合面22层压每个流路板21而设置成平行于前表面的平行流动路径50.每个连接的每个槽23之外的部分 面22对层叠方向的各平行流路50形成传热路径70a。 在第一和第二侧板30,40中形成有流入路径30a和流出路径40a。流入路径30a和流出路径40a与层叠的侧面26a,26b接合 主体20并与每个平行流动路径50连通。流入路径30a将冷却介质流入每个平行流动路径50.流出路径40a将冷却介质从每个平行流动路径50流出。制冷剂 流路由流入路径30a,每个平行流路50和流出路径40a构成。
