Abstract

A heat sink comprising a belt-shaped member arranged on a heat radiating side of a heat receiving plate and having one side having a plurality of script'"'"'s l-shaped pinlike portions. The belt-shaped member includes a capillary heat pipe.

Claims

1. A method of manufacturing a heat sink having a heat receiving plate with a heat radiating side, the method comprising the steps of:

bending a linear material at predetermined intervals;

joining cross sections of said linear material to obtain a belt-shaped member having a plurality of script'"'"'s l-shaped pinlike portions each having a base and a tip; and

joining, at locations adjacent said bases, said belt-shaped member to the heat radiating side of the heat receiving plate.

3. A method as claimed in claim 1, wherein said linear material includes a wire.

2. A method of manufacturing a heat sink having a heat receiving plate with a heat radiating side, the method comprising the steps of:

bending a linear material at predetermined intervals;

joining cross sections of said linear material to obtain a belt-shaped member having a plurality of script'"'"'s l-shaped pinlike portions; and

joining said belt-shaped member to the heat radiating side of the heat receiving plate

wherein said linear material includes a heat pipe with a small bore.
