Abstract:
1. A heat dissipation device comprising: a heat sink defining a pair of cutouts at two opposite sides thereof, the heat sink comprising two pads fixed in the pair of cutouts respectively, the pads each defining a first slot therein; a retention module supporting the heat sink thereon, the retention module extending a pair of clamping arms received in the cutouts of the heat sink, respectively, the clamping arms each defining a first slit corresponding to the first slot of the each pad of the heat sink; and a clip comprising two abutting portions rotatablely connecting with corresponding pads of the heat sink and corresponding clamping arms of the retention module, and two pressing portions slidably received in the first slots of the pads of the heat sink and the first slits of the clamping arms of the retention module, wherein when the clip is moved from an unlocked position to a locked position, the pressing portions press the pads downwardly a distance relative to the clamping arms of the retention module so that the heat sink is moved downwardly a distance relative to the retention module.
