Abstract: A heat dissipation device for dissipating heat generated from an add-on card. The heat dissipating device includes two heat sinks and two heat pipes connecting with the two heat sinks. Each of the heat sinks includes a base and a fin group mounted on a top surface of the base. Each of the heat pipes includes a connecting section and two heat-conductive sections extending from opposite ends of the connecting section. One of the two heat-conductive sections of each of the heat pipes is sandwiched between the base and the fin group of one heat sink, and another of the two heat-conductive sections is sandwiched between the base and the fin group of another heat sink.

Abstract: A vapor chamber heat sink attached to a heat-generating electronic component includes a base (10) defining an opening therein. A plurality of fins (20) is mounted on the base. A heat pipe (30) thermally connects the electronic component and the fins. The heat pipe comprises a plate-type lower portion (32) contacting a bottom surface of the base and a bottom surface (22) of the fins and overlaying a top surface of the electronic component, a plate-type upper portion (34) parallel to the lower portion contacting a top surface (24) of the fins, and a connecting portion (36) interconnecting opposite two ends of the lower and upper portions. The heat pipe is configured in such a manner so as to enhance contact area and thermal conductivity between the heat pipe and the electronic component and between the heat pipe and the fins.

Abstract: A heat dissipation device mounted on a heat-generating component of a graphics card, includes a base, a fin unit and a fan. The base is kept in intimate contact with the heat-generating component. The fin unit includes a plurality of fins arranged on the base and forming a plurality of air passages between each fin and its neighboring fins. The fan is mounted on the base, close to the fin unit and producing airflow in the air passages. The base comprises a spreader inlayed in the base. The spreader is a flattened heat pipe. A bottom surface of the spreader is in contact with the heat-generating component. The fin unit is thermally attached to a top surface of the spreader.

Abstract: A heat dissipation device (100) includes a vapor chamber (20), a heat sink (10) and a heat pipe (30). The heat sink (10) includes a plurality of fins (12). The heat pipe (30) includes an evaporating portion (32) sandwiched between the vapor chamber (20) and the fins (12) of the heat sink (10), and a condensing portion (34) extending through the fins (12). The vapor chamber (20) is attached to an electronic component (42) mounted on an add-on card (40). The fins (12) of the heat sink (10) directly contact with the vapor chamber (20) and define a recess (127) at a bottom thereof to receive the vapor chamber (20) therein.

Abstract: A heat dissipating device mounted onto a VGA card (10) includes a base (22) contacting with a GPU (12) attached on the VGA card, a cover (21) mounted on the base, and a plurality of fins (24) received between and thermally connecting the cover and the base. The base defines a slot (222) above the GPU. A fan (28) is positioned on the base for driving an airflow, wherein one portion of the airflow flows through the fins and another portion of the airflow flows through the slot and blows over other electronic components near to the GPU. Thus, rebounding of the airflow is reduced, and the heat dissipating device has better heat dissipating efficiency.
