A heat dissipation device for a heat-generating electronic component includes a heat sink () and a fan () mounted on a lateral side of the heat sink. The heat sink defines a plurality of channels () therein. A fan holder () is rotatably mounted on the heat sink. The fan is fixedly mounted on the fan holder and faces towards the channels of the heat sink. An airflow generated by the fan flows through the channels of the fan. When the fan holder rotates with respect to the heat sink, an airflow direction of the fan is changed accordingly.

Heat dissipation device

A heat sink for dissipating heat from an electronic element comprises a base with a plurality of first fins extending upwardly therefrom, a conducting member thermally contacting the base with a plurality of second fins extending from two opposite lateral face of the conducting member toward different directions and perpendicular to the first fins, a heat pipe connecting the base and the conducting member to transfer heat from the base to the conducting member.

A heat dissipation device in a computer enclosure includes a heat spreader () mounted on a CPU (), a first heat sink (), a cooling fan () coupled to the first heat sink, a second heat sink (), a heat pipe () mounted on the heat spreader and thermally connected the first heat sink and the second heat sink, a system fan () attached to the second heat sink, and a fan duct () interconnected between the cooling fan and the second heat sink. The system fan is positioned adjacent to louvers of the computer enclosure. An airflow generated by the cooling fan and the system fan flows through the first heat sink, then the fan duct, the second heat sink, and finally the louvers to leave the computer enclosure.

A heat dissipation device comprises a heat sink, a fan, and a fan holder. The heat sink includes a base and a plurality of fins arranged on the base. The fan includes a frame having an engaging flange at each corner thereof. The fan holder configured for attaching the fan to the heat sink includes a main body having two opposite sidewalls extending upwardly from two opposite sides of the main body, a peg extending through the sidewall and movable in a direction perpendicular to the sidewall, and a handle capable of operating the peg. At least one of the engaging flanges of the fan is depressed by the peg towards the main body, thereby securing the fan on the fan holder.

A heat sink includes a fin assembly () including a plurality of fin plates () and a fan () mounted on the fin assembly. Each fin plate includes a plurality of cutouts () defined on one edge thereof, and the cutouts of the fin plates cooperatively form a scraggy surface when the fin plates are assembled together. Airflow produced by the fan directly impinges on the scraggy surface thereby enhancing heat transferring between the fin plates and the airflow.

A heat dissipating assembly includes a heat sink () having a chassis (), a back plate () and a plurality of fasteners (). Each fastener includes a screw cap (), a spring (44) and a sleeve (). The screw cap and the sleeve are movably connected together. The screw cap includes a head () and a tube () extending from the head. The tube includes a first cavity () and a second cavity (). The back plate forms a plurality of posts () passing through the chassis and threadedly engaging in the first cavities of the tubes. A spring () is compressed between the first cavity of the tube and a bottom wall of the sleeve, for providing appropriate downwardly pressing force on the chassis of the heat sink against a CPU () mounted on a PCB ().

Heat dissipating assembly

A heat dissipation device comprises a seat for absorbing heat from a heat generating device. At least a heat pipe has a first section thereof thermally combined to the seat, and two second sections thereof extending from the first section and remotely from the seat. Pluralities of heat sinks are located on the seat. Each of the pluralities of heat sinks has a base and a plurality of fins integrally extending from the base and is made of aluminum extrusion. The bases of the heat sinks thermally sandwich the two second sections of the at least a heat pipe therebetween. At least one of the bases of the heat sinks is angled or perpendicular to the seat.
