A heat dissipation device assembly for dissipating heat from a plurality of electronic components mounted on a printed circuit board, includes a heat sink (10) contacting one of the electronic components, a pair of fans (20) attached on a lateral side of the heat sink, and a fan duct (30) fixed on the fans. A plurality of guiding members (322, 346) are formed inwardly from the fan duct to be located in an interior of the fan duct. The guiding members are used for guiding a screwdriver (40) to accurately fit with screws (50) preassembled to the heat sink. Thus, the screws can be quickly and easily fastened by the screwdriver to mount the heat dissipation device assembly on the printed circuit board.

A heat sink assembly includes a heat sink and a clip assembly received in the heat sink. The clip assembly comprises a clip and a movable fastener pivotally connected to the clip via a pair of supporters. Each supporter defines a pivot hole deviated from a center thereof and a retaining slot above the pivot hole. The clip comprises a main body received in the heat sink and two arms extending from the main body and pivotally received in the retaining slots of the supporters. The movable fastener pivotally extends in the pivot holes of the supporters. The movable fastener moves relative to the heat sink and causes rotation of the supporters in a matter such that a distance from the main body of the clip to a bottom of the heat sink is changed, whereby the clip assembly can provide adjustable spring force acting on the heat sink.

A heat dissipation device includes a first heat sink, a second heat sink located on the first heat sink, a third heat sink located on the second heat sink, and a heat conducting member formed by bending a flat, plate-like member and connecting the first, second and third heat sinks. The heat conducting member includes a heat absorbing section contacting with the first heat sink, and first and second heat dissipating sections extending inwards from upper ends of first and second connecting sections extending upwardly from two ends of the heat absorbing section, respectively. The first heat dissipating section is sandwiched between the first and second heat sinks, and the second heat dissipating section is sandwiched between the second and third heat sinks. A width of the first and second heat dissipating sections is identical to that of the second heat sink.

A heat dissipation device assembly includes a heat dissipation device for dissipating heat from an electronic element and a protective device assembly. The heat dissipation device includes a base with fasteners extending therethrough, a plurality of fins arranged on a top of the base, and a heat conducting plate attached on a bottom of the base. A thermal interface material is spread on a bottom surface of the heat conducting plate. The protective device assembly includes a first cover attached to a bottom of the heat conducting plate and a second cover separated from the first cover and attached to a lateral side of the base. The first cover protects the thermal interface material from being contaminated and the second cover protects the fasteners from dropping from the base, when the heat dissipation device is transported.

A heat dissipating assembly for dissipating heat from a CPU and a VRM simultaneously includes a base (10) contacting the CPU, a heat sink (20) mounted on the base, a pair of fans (30) attached on a front side of the heat sink, and a fan duct (40) secured to the fans. The fan duct has a first inlet (440) through which a part of airflow flows into the fan duct, a second inlet (460) through which another part of the airflow flowing into the fan duct. The another part of the airflow also flows through the VRM so it can cool the VRM. The fan duct further has an outlet (480) for allowing the airflow generated by the fans to blow to the heat sink.
