Abstract
A heat sink assembly (10) includes a heat sink (12) and a wire clip (14). The heat sink includes a base (120) and a plurality of fins (124) mounted on the base. A channel (126) is defined between two neighboring ones of the fins. A pair of points (1250) are punched on one of the fins and received in the channel. The wire clip includes a main body (140), first and second legs (141, 142) extending from opposite ends of the main body. The wire clip intervenes across the points and extends through the channel such that the main body is received in the channel and the first and second legs are located at opposite ends of the channel. Thus, the wire clip is prevented from dropping from the channel in a direction parallel to the channel.
Claims18
A heat sink assembly for dissipating heat comprising:
- a heat sink having a base and a plurality of fins extending from the base, a pair of points being punched on one of the fins, a channel being defined between adjacent two fins, the points being received in the channel;
- and
- a wire clip positioned on the heat sink, the wire clip comprising a main body;
- wherein the main body of the wire clip intervenes across the points, downwardly presses the heat sink, engages upwardly against the points, and extends through the channel such that the main body is received in the channel to prevent the clip from sliding off from the channel in a direction parallel to the channel;
- and
- wherein the main body of the wire clip is arced and elongated and has a substantially V-shaped configuration.
(canceled)
An electronic device assembly comprising:
- a printed circuit board having a pair of clasps formed thereon;
- a heat sink having a base and fins extending from the base, a receiving channel being defined between the fins, a pair of points punched from one of the fins at one of opposite sides of the receiving channel and toward the receiving channel:
- a wire clip comprising:
- a main body comprising a pressing portion and two arms extending slantwise upwardly relative to the pressing portion;
- and
- a pair of legs extending away from two free ends of the arms of the main body and located at opposite lateral sides of the receiving channel of the heat sink, respectively, each leg having a hooked foot at a distal end thereof buckled with a corresponding clasp of the printed circuit board;
- wherein the points abut downwardly against the arms of the main body of the clip when the hooked feet of the clip are buckled with the clasps of the printed circuit board to prevent the heat sink from sliding relative to the clip along the receiving channel;
- and
- wherein flanges are bent from upper and lower edges of the fins for preventing the clip from dropping from a top of the receiving channel.
(canceled)
(canceled)
A heat sink assembly comprising:
- a heat sink comprising a base and a plurality of fins extending upwardly from the base, wherein one of the fins is formed with a pair of points protruding into a channel between the one of the fins and an adjacent fin;
- a wire clip received in the channel, having a substantially V-shaped main body with two arms at two end portions thereof, respectively, first and second legs extending outwardly from free ends of the arms, respectively, wherein the free end of one of the arms near the first leg is located above one of the points near the first leg and the other one of the arms near the second leg abuts upwardly against the other one of the points.
