Heat sink assembly
First Claim
1. A heat sink assembly comprising:
- a heat sink having a base and a plurality of fins extending from the base, at least one void defined in the base, and a slot defined through the fins;
a fan; and
a fixing device fastening the fan to the heat sink, the fixing device comprising a body and a plurality of resilient legs depending therefrom, the legs having engaging portions for engaging with the corresponding void of the heat sink and thereby attaching the fan to the heat sink, the body having at least one engaging member extending into the slot of the fins of the heat sink for preventing the fixing device from moving laterally.

Abstract
A heat sink assembly includes a heat sink (40), a fan (30), and a fixing device (10). The fan has a chassis (32), and a hollow cylinder (34) extending upwardly therefrom. The heat sink has a base (42) which defines a pair of grooves (422) in a bottom surface thereof, and a plurality of fins (44) with a transverse slot (442) defined through the fins. The fixing device includes a body (12), and four resilient legs (14) depending from corners of the body. A pair of lips (22) depends from opposite edges of the body. A tab (24) extends inwardly from each lip, for engaging in the slot of the heat sink and thereby preventing the fixing device from moving laterally. A hook (18) is formed at a distal end of each leg, for engaging in the grooves and thereby attaching the fan to the heat sink.
