Abstract: A heat dissipation assembly (100) includes a retention frame (90), a heat sink (80), a fan holder (10), a pair of clips (60) and a fan (20). The heat sink is mounted on the retention frame and forms a pair of shoulders (822) at opposite sides thereof. The fan holder includes a fan duct (40) surrounding a top portion of the heat sink and including a pair of supports mounted on the shoulders, and a holding frame (30) detachably mounted on the fan duct. The clips are mounted on the supports and engaged with the retention frame. One side of the holding frame is pivotally engaged with the fan duct, an opposite side of the holding frame forms a latching leg (33) that is engaged with an ear (412) formed at the fan duct. Three catching arms extend from the holding frame and retain the fan in the holding frame.

Abstract: A heat dissipation device for dissipating heat from an electronic package (80) includes a heat sink (10) and a fan (30). The heat sink includes a base (12) and a plurality of fins (14). The base has a first surface (122) in thermal contact with the electronic package and a pair of sloped heat dissipation surfaces (126). The fins are perpendicularly attached on the heat dissipation surfaces. The fan is supported on the heat sink. During operation of the heat dissipation device, the cooling air is drawn into the heat sink by the fan and exits the heat sink along the heat dissipation surfaces.
