ABSTRACT:
A heat dissipation device includes a heat sink, a retention module and a clip having two clipping portions for securing the heat sink to the retention module. The heat sink includes a base for contacting with a heat generating electronic device. The base defines two flutes in two opposite sides thereof respectively. Each of the flutes is located at a middle of a corresponding one of the two opposite sides. The retention module is located around the electronic device and includes a bottom wall for supporting the heat sink. Each clipping portion is rotatablely connected to the retention module and includes a pressing portion which is rotatablely received in the flute of the base and presses the base to the bottom wall of the retention module when the clip is rotated to a position locked to the retention module.
