Abstract

A heat sink includes a base plate ( ), and a plurality of fins ( ) mounted on the base plate. Each fin includes a main body ( ), and two upper locking members ( ). Two retaining holes ( ) are defined in the main body. Each locking member includes a horizontal part ( ), and a vertical part ( ). A slot ( ) is defined in the horizontal part. A key ( ) is formed in the vertical part. In assembly, a second fin is moved relative to a first fin until the locking members of the second fin are received in the corresponding slots of the first fin, and the keys of the second fin snappingly engage in the corresponding retaining holes of the main body of the first fin. Thus, the two fins are interlocked together. The other fins are then sequentially interlocked with the second fin onward, in similar fashion.
