Claims

[Claims for Utility Model Registration] In a heat sink in which a plurality of fins are provided in a row on a flat heat sink base part, spaced apart from each other almost perpendicularly to the surface of the heat sink base part, in the height direction of the fins. The plurality of fins are partially cut out, and the impeller is attached to the fin or the heat sink base so as to be located in the space obtained by partially cutting out the plurality of fins. heat sink.
