Method of fabricating a heat sink

摘要

A method for fabricating a straight fin heat sink (50) of the type having a base (52) and a plurality of fins (54) extending from the base is disclosed. Each fin (54) of the plurality of fins of the heat sink is spaced from one another a predetermined distance and lies along a plane generally parallel to planes of the other fins of the plurality of fins. The method includes: providing a die (20) configured to produce a heat sink (30) having a base (32) and a plurality of fins (34) attached to be base in a radial fashion about the base from at least one side of the base; extruding a blank of material through the die (20) to produce the heat sink (30); and compressing the plurality of fins (34) with a compression tool (40) so that the plurality of fins (54) extend from the base along planes generally parallel to each other.
