HEAT SINK AND METHOD OF ITS MANUFACTURING AND COOLER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a heat sink, a method of its manufacturing and a cooler employing it, in which the dissipation of the heat generated by a heatfull electronic component heat can be enhanced while reducing the size and weight. SOLUTION: The color comprises a heat transfer part contacting a heat generating body to be cooled, a heat dissipating part comprising fins bonded to the heat transfer part, and a cooling fan 4 disposed directly above the heat dissipating part wherein the heat transfer part of the heat sink comprises struts 2 of columnar structure in order to enhance the effect for spreading heat generated from a heat generating body 3 and pin type fins 1 are arranged on the opposite sides of the struts 2 other than the heat receiving face.
