A heat sink clip () includes a main body (), a post (), a spring () and a cammed handle (). The main body includes a horizontal portion () and two locking arms (). A locking hole () is defined in an end of each locking arm for engaging with catches () of a socket (). The post has a pressing block () at a bottom portion and a cutout () at a top portion. The spring is placed around the post and rests on the pressing block The post extends through a through aperture () of the horizontal portion, and the cutout pivotally receives a cam () at one end of the handle. When the handle is pressed, the horizontal portion of the main body is raised by the decompressed spring, so that the locking arms tightly engage with the catches of the socket.

Heat sink clip with cammed handle

A heat sink assembly of the present invention includes a printed circuit board (), a retention module (), four pins (), a heat sink () and a clip (). The printed circuit board () has an electronic package () mounted thereon. The retention module () is integrally formed, substantially rectangular, and has a symmetrical configuration. The retention module () defines an opening () therein for surrounding the electronic package (). Four positioning holes () are defined in four corners of the retention module (). In assembly of the heat sink assembly, the pins () are interferentially positioned in the positioning holes () of the retention module (). Portions of the pins () extending out beyond the retention module () are welded to the printed circuit board (). The clip () cooperates with the retention module () to press the heat sink () against the electronic package ().

Heat sink assembly with retention module and clip

A heat dissipating device includes a heat sink and a clip attached on the heat sink. The heat sink includes a solid trunk and a plurality of fins extending radially outwardly from a circumference of the trunk. A rectangular extension portion is formed at a bottom end of the trunk. A pressing portion extends from the extension portion and abuts against the clip toward the heat sink in an axial direction of the heat sink. The clip defines a rectangular opening fittingly receiving the extension portion to thereby form a positioning structure for preventing the clip from moving relative to the heat sink in a circumferential direction of the heat sink.

Heat dissipating device

A heat dissipating device includes a heat sink forming a pressing portion thereon and a clip. The heat sink includes a hollow dissipating member and a column-shaped core, and the clip includes an integrally formed body defining a round hole therein. The pressing portion extends beyond the clip and presses the body of the clip on the heat sink. The method for manufacturing the heat dissipating device as above-mentioned includes the following steps: providing a heat sink with a collar formed thereon; providing a clip on the heat sink with the collar extending beyond the clip; having the collar deformed under pressure to form a pressing portion pressing the clip on the heat sink.

Heat dissipating device and method for manufacturing it

A heat dissipation device includes a heat sink () and a fan () located above the heat sink for providing airflow. The heat sink includes a base () and a heat dissipating part () arranged on the base. The heat dissipating part includes a plurality of fins (), each adjacent pair of the fins defines a channel () therebetween. The heat dissipating part defines a plurality of passages () disposed diagonally thereat and perpendicular to the channels. The channels and the passages are oriented consistently with the airflow of the fan.

Heat dissipation device

A heat dissipating device for a heat generating unit, includes a heat sink placed on the heat generating unit, and two clip members located at opposite sides of the heat sink for securing the heat sink to the heat generating unit. Each clip member includes an operating member movably attached to the heat sink, and a fastening member connected with the operating member. The operating member is movable from a lower position to an upper position to cause the bottom portion of the fastening member to move upwardly via the operating member acting on the fastening member.

Heat dissipating device incorporating clip

A heat sink clip () includes a main body, a post (), and a spring (). The main body includes a longitudinal portion (), first and second locking arms () extending downwardly from opposite ends of the longitudinal portion. The longitudinal portion defines a through aperture () in a middle thereof. Two hooks () are respectively formed at free ends of the first and second locking arms for engagement with catches () of a socket (). The post has a pressing portion at a bottom thereof for being fittingly received in a blind hole () of a heat sink (). The post extends through the through aperture of the longitudinal portion. The resilient element is disposed around the post below the longitudinal portion.
