Abstract
A heat dissipating apparatus (100) includes a heat sink (20) and a plurality of fastening elements (10). The heat sink includes a base (22) and a plurality of fins (24). The fastening element includes a head (12), a resilient member (14) and a connecting member (16). The connecting member includes two blocks (166). The base of the heat sink defines a plurality of through holes (222b) therein for extension of the connecting members of the fastening elements, wherein two opposite cutouts (222c) are defined in the base and communicating with each of the through holes. After the connecting member and the two blocks are downward extended through the through hole and the cutouts, respectively, the connecting member is rotated a degree so that the blocks securely abut against a bottom surface of the base.
