    • 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.
    • 示例性的散热装置包括圆形散热器和固定框架。 散热器在其外周表面限定接收凹部。 固定框架包括围绕散热器设置的周边侧板,并且固定腿对应于从侧板向下延伸的散热器的接收凹部。 固定框架包括从侧板的内表面向内延伸的块和从固定腿向内延伸的突出构件。 散热器可旋转地容纳在固定框架中,散热片的顶部邻接块体。 当散热器处于解锁状态时,突出部件分别与接收凹部对准。 当散热器旋转到锁定状态时,突出部件邻接散热器的底部。
