Abstract: A heat dissipation apparatus includes a retention module (10), a heat sink (20) disposed on the retention module, a fastening cover (23) covering the heat sink, and a plurality of fasteners (30) connected with the retention module and the fastening cover for mounting the heat sink onto a heat generating electronic component (50). The fastener includes a fastening member (31) and an operating member (32). The fastening member has a first end (313) engaged with the retention module and a second end (311) opposed to the first end. The operating member includes a resilient pressing portion (321) pivotably connected with the second end of the fastening member and contacting with the fastening cover, and an operation portion (322) connected with the pressing portion.

Abstract: A heat sink clip and an assembly incorporating such clip are provided. The heat sink clip comprises: a body, an actuating member and a movable fastener. The body has a securing portion formed at one end thereof. The actuating member is pivotably mounted to the securing portion of said body and has a main body. The main body defines an open aperture therein. The movable fastener is pivotably connected to the open aperture of the actuating member. The actuating member is turnable relative to the body between an unlocked position and a locked position.

Abstract: A cooling fan includes a fan housing (50) having a central tube (52), a bearing structure received in the central tube, a stator (60) mounted around the central tube, and a fan blade set (70). The bearing structure includes a shaft (30) being rotatably received in the central tube and connecting to the fan blade set. An inner bearing (20) is fixedly mounted around the shaft to rotate with the shaft. Upper and lower outer bearings (10) are fixedly mounted into the central tube and are mounted around two opposite ends of the inner bearing, respectively. The inner and outer bearings are made of magnetic materials. The inner bearing floats between the outer bearings whereby rotation of the shaft does not cause the inner and outer bearings to wear.
