A HEATSINK AND A METHOD AND AN ASSEMBLY FOR FORMING THE SAME

摘要

A heatsink (1) is formed from a block-like extruded or machined base member (10) and a number of planar fin members (12). The fin members may comprise "U"-shaped members. The fin members are secured in slots (14) formed in the base member and are preferably formed of the same material as the base member to improve the efficiency of the thermal contact therebetween. The fin members are each preformed to comprise a number of fin portions (12a) which extend upwardly from the base member of the assembled heatsink.
