Abstract: A heat sink fastener includes a main body, a piercing body and an operating member. The main body has a pressing part for pressing a heat sink toward a heat-generating component. An engaging part and a latching leg are disposed at opposite ends of the main body. The piercing body includes a piercing part piercing through the engaging part, and a latching part below the piercing part. The operating member includes a cam pivotally connected to the piercing part and rotatable between locked and unlocked positions. At the locked position, a protrusion formed on the cam abuts a lateral edge of the piercing part to prevent the operating member from spontaneously rotating back to the unlocked position. A bent flange is formed at a periphery of the cam and engages with the engaging part.

Abstract: A heat dissipation device includes a heat sink and a fixing base for securing the heat sink to a heat-generating device. The heat sink includes a base and a pair of flanges formed on two opposite sides of the base. The fixing base includes a pair of side plates formed on a first set of two opposite sides thereof. A pair of resilient barbs extends inwards from an end portion of each side plate. The fixing base is placed on the heat sink and the resilient barbs tightly clasp first two opposite sides of the heat-generating device to press the base of the heat sink towards the heat-generating device. The flanges of the base of the heat sink abut second two opposite sides of the heat-generating device to avoid movement of the heat sink along a direction perpendicular to the flanges.

Abstract: A heat dissipation device includes a heat sink, a retention module and a locking device for securing the heat sink to the retention module. The heat sink includes a base for contacting with a heat-generating component. The retention module includes a bottom wall and a first spring clip secured at one side thereof. The locking device is pivotably connected to the retention module and includes a second spring clip attached thereon. The heat sink rests on the bottom wall of the retention module with an end thereof being pressed by the first spring clip, and an opposite end thereof being pressed by the second spring clip. The locking device can be at a released position where the locking device is pivotable, so that the heat sink is removable from the retention module, and a locked position where the locking device presses the base of the heat sink.

Abstract: A heat dissipation device includes a computer enclosure having a panel, a heat sink installed in the computer enclosure, a fan mounted on the heat sink, a duct and a dust mask. The panel defines an air intake therein. The duct includes a first end portion mounted onto the fan and a second end portion connected to the air intake of the panel so that a sealed access is provided for air straightly flowing from the air intake to the heat sink. The dust mask is removably mounted on the panel and covers the air intake for hindering dust particles from entering the computer enclosure.

Abstract: A fastener (10) for mounting a heat-radiator (20) to an electronic device (30) on a circuit board (40) is disclosed. The heat-radiator and the circuit board have aligned holes (22, 44). The fastener includes a head (11) having an upper portion (112) with a large diameter and a lower portion (113) with a smaller diameter, a cylindrical spring (14) captured around the lower portion of the head for exerting a spring force against the heat-radiator, and a metallic wire (15) having a first end portion fixed on said head and a second end portion bent to form an engaging portion (152). The engaging portion of the metallic wire compressively passes through the aligned holes of the heat-radiator and the circuit board and is engaged with an underside of the circuit board.

Abstract: A heat dissipating device assembly for an electronic components (70), includes a heat sink (10) for contacting the electronic component, and a locking device (20) and a back plate unit (40) for cooperatively mounting the heat sink to the electronic component. The locking device includes a retention module (28) located around the electronic component for supporting the heat sink thereon, and a clip (30) pivotably attached to the retention module. The clip includes a pressing portion and a pushing portion. The clip is pivotable between a first position in which the clip presses the heat sink toward the electronic component and a second position in which the clip pushes the heat sink in a direction away from the electronic component.

Abstract: A heat dissipation device assembly includes a heat sink (20) placed on an electronic component (52) which is mounted on a printed circuit board (PCB) (50) and including a pair of shoulders (23) on opposite sides thereof, a pressing part (30) including a pair of pressing portions (36) supported on the shoulders and a pair of locking portions (34) spaced from the shoulders, a sliding part (40) slidably attached to the pressing part and including a pair of locking portions (41) spaced from the shoulder, and a back plate (60) mounted below the PCB and including four posts (61) extending through the PCB and the heat sink to resilently engage with the locking portions. Each locking portion defines a locking opening (33, 43) including an entrance (33a, 43a) and a locking slot (33b, 43b), the post being capable of extending through the entrance to engage in the locking slot.

Abstract: A heat sink mounting assembly includes a socket (90) having first and second side, a retaining clip (10) cooperating with the socket to sandwich a heat sink (70) therebetween. A pair of ears (92) is formed at the first and second sides of the socket. The retaining clip includes a pressing body (11) having first and second ends, a first leg (14) extending from the first end thereof and engaging with one ear, a spring (50) attached to the pressing body, and a second leg (30) attached to the second end thereof and biased by the spring. When the second leg is pressed down toward the socket, the spring biases the second leg upwardly, so that the second leg is resiliently engaged with the other ear. Thus, the heat sink is secured between the socket and the retaining clip.
