PURPOSE:To contrive improvement in cooling efficiency by a method wherein good heat-conductive epoxy resin is added between the fins implanted into the groove formed in a metal planar member, which constitutes the main body of a heat sink, in the direction of stream of a cooling medium fluid and the metal planar member. CONSTITUTION:A part of the planar fins 2 protrudingly formed on one surface of the metal planar member 1, which constitutes the main body of a heat sink, is inserted into the groove 4 formed in the direction A of the stream of a cooling medium fluid 3 on the metal planar member 1, and good heat-conductive epoxy resin 5 is added between the inserted fins 2a and the metal planar member 1. Besides, it is advantageous than the inserted fins 2a and the molded fins 2 are arranged alternately with each other. As a result, high cooling effect can be obtained when the heat sink is used at high temperature. |
