摘要:
A heat sink assembly includes a base, a fin group and a heat pipe connecting with the base and the fin group. The fin group includes a plurality of fins. Each of the fins defines a recess at a lower portion thereof. The heat pipe includes an evaporating portion extending through the base and a condensing portion extending through the fin group. The base is interferentially fitted into the recesses of the fins. The base, the fin group and the heat pipe directly and intimately connect with each other. The recess and the base have correspondingly T-shaped profiles. Each fin forms a bended flange defining the recess. The bended flange intimately contacts with the base and the evaporating portion of the heat pipe.

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 dissipation device includes a first base plate (10), a fin group (30) arranged on the first base plate, a first heat pipe (50) attached on the first base plate and the fin group and a second heat pipe (60) attached on the first base plate and extending across the fin group. Each of the first and second heat pipes includes an absorbing section and a dissipating section. The absorbing sections of the first and second heat pipes are L-shaped and oriented in opposite directions and dissipating sections of the first and second heat pipes are oriented perpendicular to each other, whereby heat from the first base plate attached with an electronic component can take more different dissipating-paths from the first base plate to the fin group.

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.
摘要:
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.
