Abstract

A heat dissipation device includes a heat sink, a retention module and a rotatable fastener for securing the heat sink to the retention module. The retention module includes two supporting ribs and a positioning block above one of the supporting ribs. The rotatable fastener is rotatably received in the retention module and includes an actuating portion and a pressing portion fastened to the actuating portion. The heat sink rests on the supporting ribs of the retention module with an end thereof being pressed by the positioning block, and an opposite end thereof being pressed by the pressing portion. The rotatable fastener can be rotated to an unlocked position wherein the pressing portion is moved away from the opposite end of the heat sink, so that the heat sink is removable from the retention module.
