摘要： A structure for cooling an electronic component includes a heat sink attached to the component, an inner air duct extending into a central portion of the heat sink, and an outer air duct extending into an outer portion of the heat sink. In inner fan, within the inner air duct, moves air in one direction, while an outer fan, in the outer air duct, moves air in the other direction. The fans may be built as separate rotors, or as separate portions of a single rotor.

摘要： A heat sink having an air flow director on each of multiple fins attached to a heat sink base. The air flow directors direct most of the air flow from dual push-pull fans towards a midline and a geometric center of the heat sink base, which is above the hottest part of the integrated circuit (IC) package being cooled by the heat sink. The rest of the air flow from the push-pull fans impinges against the air flow directors, providing additional cooling to the fins.

摘要： A fan sink that includes a dual impeller push-pull axial fan and a heat sink to cool a hot electronic device is presented. The axial fan has a hub motor, a first impeller that is radially proximate to the hub motor, and a second impeller that is radially distal to the hub motor, wherein the first impeller pushes air in a first direction and the second impeller pulls air in a second direction. The heat sink is oriented between the axial fan and the hot electronic device such that the hot electronic device, the heat sink, and the axial fan are axially oriented, wherein cool air is forced onto the heat sink by one impeller in the axial fan, and wherein heated air from the heat sink is removed by an other impeller in the axial fan.

摘要： A heat sink having air flow directors on each of multiple fins attached to a heat sink base. The air flow directors direct air flow from dual fans towards a geometric center of the heat sink base, which is above the hottest part of the integrated circuit (IC) package being cooled by the heat sink. In one embodiment, a protrusion in the geometric center of the heat sink base provides additional cooling from air impingement, and also directs air towards the upper portions of the fins. The use of dual fans allows the fans to run at a lower speed than a single fan, thus reducing an overall fan acoustic level. Furthermore, the dual fans allow for a backup fan if one of the fans should fail.

摘要： A heat sink having graduated lengths of fins, with the tallest fins being in the center of the heat sink to provide maximum heat removal from a mated integrated circuit (IC) chip. Dual fans impinge air against the fins, and particularly the tallest fins, to provide a highly efficient system for heat removal from the IC chip. By reducing the size of the lateral fins, additional space is made available for the dual fans. The use of the dual fans allows the fans to run at a lower speed that a single fan, thus reducing an overall fan acoustic level. Furthermore, the dual fans allow for a backup fan system if one of the fans should fail.
