Abstract:
1. A heat dissipation device, comprising: a round heat sink defining a plurality of receiving depressions at a peripheral surface thereof; and a fixing frame comprising a top plate, a peripheral side plate extending downwards from a periphery of the top plate, a plurality of fixing legs extending downwards from the peripheral side plate, and an elastic member disposed on the peripheral side plate, the peripheral side plate encircling the heat sink, and a plurality of protruding members extending inwardly from the fixing legs; wherein the heat sink is received in the fixing frame; when the heat sink is in an unlocked state, the protruding members of the fixing frame align with corresponding receiving depressions of the heat sink; and when the heat sink is rotated in a first direction relative to the fixing frame to a locked state, the protruding members abut a bottom of the heat sink thereby limiting axial movement of the heat sink relative to the fixing frame and the elastic member is received in a corresponding receiving depression and limits rotation of the heat sink relative to the fixing frame in a second direction that is opposite to the first direction.
