Patent ID: 7990712

Claim:
A heat sink used in an interface card, comprising: a supporting base having a side; a first heat-dissipating body mounted on the supporting base, the first heat-dissipating body being constituted of a plurality of heat-dissipating pieces, each heat-dissipating piece being arranged obliquely with respect to the side, whereby air passing through the first heat dissipating body exits the first heat dissipating body at an oblique angle with respect to the side; a second heat-dissipating body overlapping on the first heat-dissipating body, the second heat-dissipating body comprising a plurality of heat-dissipating pieces; at least one heat pipe having an evaporator section sandwiched between the supporting base and the first heat-dissipating body as well as a condenser section extending from the evaporator section and connected to the second heat-dissipating body; a fan mounted to the supporting base and located beside the first heat-dissipating body and the second heat-dissipating body; and at least one heat-conducting pipe having a heated section sandwiched between the supporting base and the first heat-dissipating body as well as a heat-releasing section, wherein the supporting base comprises a fixing plate and a heat-conducting block fixedly inserted into the fixing plate, and wherein the fixing plate is provided with a trough for allowing the heat-releasing section to be inserted therein, and the heated section is adhered to the heat-conducting block.
