Abstract: A heat dissipating apparatus includes a retention module (20) forming clipping portions (26) thereon, a heat sink (10) mounted to the retention module, and a clip (30) engaged with the retention module and the heat sink. The clip includes a resilient clipping member (32) clasped with the clipping portions, and an operating member (34) pivotally mounted to the clipping member. The operating member includes a longitudinal pole (340) rotating about an axis thereof. The longitudinal pole forms a supporting portion (341) to support the clipping member away from the retention module in the process of its rotation from unlock to lock position. At the lock position, the clipping member securely engages with the clipping portions of the retention module, and the heat sink is downwardly pressed by the longitudinal pole to have an intimate contact with a heat generating component (8).

Abstract: A heat dissipating apparatus includes a heat sink (20) having a base plate (22) for contacting an electronic component (10). A number of main fins (24) extend from the base plate. A cooling fan (30) is mounted on the heat sink. A center of the cooling fan offsets in a first direction from a center of the electronic component, so that a portion of the cooling fan that generates more and stronger airflows than the center of the cooling fan does is aligned with the center of the electronic component.

Abstract: A locking device for mounting a heat sink (50) to a heat generating component surrounded by a retention module (60). The locking device includes a first locking member (10), a second locking member (20) and an operating member (30). The first locking member secures a first side of the heat sink with a first side of the retention module. The second locking member is disposed at a second side of the heat sink opposing to the first side. The operating member is pivotably attached to the second locking member and is capable of acting upon the heat sink to drive the second locking member moving from a released position to a locked position. The operating member has a cam (31) and a free end. At the locked position, the cam downwardly depresses the heat sink and upwardly pulls the second locking member, and the free end locks at the retention module.

The catching portion is without adhesive thereon.

Abstract: A heat dissipating apparatus (10) for dissipating heat from a heat-generating electronic component includes a heat sink (14), a resilient clipping member (162), and an operating member (164). The heat sink contacts with the heat-generating electronic component, and includes a fin assembly (144) which defines a channel (146) therein. The resilient clipping member is received in the channel of the heat sink for mounting the heat sink on the heat-generating electronic component. The operating member is pivotally mounted to the clipping member. At least one portion of the operating member is mounted between the fin assembly and the clipping member. The at least one portion can move from an unlock position to a lock position to support the clipping member away from the heat-generating electronic component.

Abstract: A retaining device (20) for mounting a heat sink (30) to an electronic device (40) includes an unitary metal wire clip (22), a locking device (26) and a camming member (24). The clip includes a pair of spaced apart pressing beams (221), at least one latching beam (223) and a crossbeam (225). The latching beam is set at one side of the pressing beams. The crossbeam extends between the pressing beams at an opposite side thereof. The camming member is pivotably attached to the locking device and includes a cam (242) being engageable with the crossbeam. The camming member is pivotable relative to the locking device from an unlocked position to a locked position and the pressing beams force the heat sink into close contact with the electronic device when the camming member is located at the locked position.
