Abstract:
A heat dissipation device removing heat from a memory module includes two conducting plate clipping the memory module and an elastic member. Each conducting plate includes a lower part and an upper part. The two lower parts of the two conducting plates abut against two opposite sides of the memory module, respectively. The two upper parts of the two conducting plates are pivotably connected together and located above the memory module. The elastic member is located between the two upper parts and urges the two lower parts towards the memory module. The upper part of each conducting plate is slantwise at an obtuse angle to the lower part to make the two upper parts of the two conducting plates splay upwardly.
Abstract:
A heat dissipation device removing heat from a heat generating electronic device on a printed circuit board includes a base, a plurality of fins attached to the base and a clip for mounting the base and the fins onto the heat generating electronic device. Each of the fins defines a closed through hole therein. The holes of the fins cooperatively define a channel. The clip includes a locking beam extending through the channel of the fins and two fasteners engaging the locking beam mounting the base and the fins onto the heat generating electronic device.
Abstract:
A blind (10) for a projector includes a bracket (20) mounted to the projector, and a folded fin (30) fixed on the bracket and covering a hot air vent of the projector. The folded fin includes a plurality of parallel fins (32) and a plurality of upper and lower tabs (34, 36) interconnecting the fins. Each of the fins defines an angle of 135 degrees with a plane defined by the lower tabs. Furthermore, a projection of each of the fins on the plane defined by the lower tabs overlaps a part of a corresponding adjacent fin. Thus, the blind can prevent a light leakage from the projector, while allow a heated airflow to be expelled out of the projector simultaneously.

Abstract:
A heat dissipation device for dissipating heat from heat-generating components on a printed circuit board includes a cover for covering the printed circuit board and a radiator mounted on the cover. The cover defines a plurality of holes corresponding to the heat-generating components on the printed circuit board. The radiator includes a plurality of contacting portions extending through the holes of the cover for contacting the heat-generating components, respectively. The cover and the radiator are made of different materials by different manufacturing techniques, i.e. aluminum die-casting and aluminum extrusion.
Abstract:
A heat sink (10) for removing heat from heat-generating devices includes a plurality of fins (12) interconnected together by a fastener (20) extending therethrough. Each fin comprises a main body (14) and a flange (16) bent from an edge of the body. The main body has a thickness and defines a through hole (141, 142, 143) therein. The fastener comprises a plurality of alternating bars (200) and positioned portions (212). Each positioned portion has a same thickness as the main body and is accommodated in the through hole. Each bar is sandwiched between two adjacent main bodies, for fixing the fins in position and preventing the fin from sliding along a length direction of the fastener. The bar has a width larger than a diameter of the through hole.
Abstract:
A heat dissipation device for removing heat from an electronic device and electronic components, includes a base plate in contact with the electronic device, a first fin set and a second fin set mounted on the base plate. The first fin set includes a plurality of first fins perpendicularly arranged on the base plate. The second fin set includes a plurality of second fins attached to a lateral side of the first fin set and perpendicular to both the first fins and the base plate. A fan is mounted on tops of the first fin set and the second fin set to cover both of them. Air generated by the fan flows through the first and second fin sets to cool the electronic components mounted on orthogonally neighboring sides of the heat dissipation device.
