Abstract: A fan holder is used for securing a fan to a heat sink. The fan holder includes a cover mounting the fan thereon, and a base mounting the cover thereon. The cover includes a plurality of separate claws and at least one jut. The base includes a through hole receiving the claws of the cover therein, thereby rotatably mounting the cover onto the base, and at least one slot. The at least one slot has a first pit and a second pit at two ends thereof respectively. The at least one jut is slidable along the slot between the first pit and the second pit to have the cover rotatable between a first location and a second location.

Abstract: A locking device for securing a heat sink to a heat generating electronic device includes a retaining member attached to the heat sink and a plurality of fasteners positioned to the retaining member. The retaining member includes a frame and a plurality of fastening feet integrally formed with the frame by metal extrusion. The frame has an opening for receiving a bottom protrusion of the heat sink therein. Each fastening foot has a slot therein communicating with the opening of the frame and defines a fastening hole. The fasteners are respectively positioned in the fastening holes of the fastening feet of the retaining member.

Abstract: A heat sink assembly (100) includes a heat sink (10) having a plurality of fins (14), a fan handle (24) buckled with the fins and a fan (30) mounted on the heat sink (10) via the fan handle. The fan handle includes a retaining body (26) clasping two adjacent fins having a space therebetween. A screw (22) is extended through the fan and into the space of the two adjacent fins. The retaining body includes a pair of opposite lateral walls (260) clamping opposite sides of the two adjacent fins, for preventing the two adjacent fins from being over expanded outwardly during the insertion of the screw into the space.

Abstract: A heat dissipation assembly includes a blower holder, a blower, a first heat sink and a second heat sink. The blower includes an inlet and an outlet and is attached to the blower holder. The blower holder is secured to the first heat sink with the inlet of the blower exposed to the first heat sink. The second heat sink is mounted to the blower holder and confronts the outlet of the blower. The second heat sink thermally connects with the first heat sink via heat pipes.

Abstract: A clip for heat sink comprises an inverted T-shaped retaining member and an L-shaped operation member pivotably connected to the retaining member. The retaining member has a detaining portion defining several openings and a connecting portion extending from the detaining portion. The operation member has a press portion for bearing against the heat sink and a holding portion for being grasped extending from the press portion. The operation member is capable of being driven to rotate from a first position to a second position to cause the detaining portion to interlock with a retention module provided on a printed circuit board, thereby securing the heat sink to an electronic element package on the printed circuit board.
