Abstract
An exemplary heat dissipation device includes a round heat sink and a fixing frame. The heat sink defines receiving depressions at an outer peripheral surface thereof. The fixing frame includes a peripheral side plate disposed around the heat sink and fixing legs corresponding to the receiving depressions of the heat sink extending downwardly from the side plate. The fixing frame includes blocks extending inwardly from an inner surface of the side plate and protruding members extending inwardly from the fixing legs. The heat sink is rotatably received in the fixing frame with a top of the heat sink abutting the blocks. When the heat sink is in an unlocked state, the protruding members align with the receiving depressions, respectively. When the heat sink is rotated to a locked state, the protruding members abut a bottom of the heat sink.
