  • Patent number: 7019969
    Abstract: 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.

  • Patent number: 7019976
    Abstract: A heat sink has a flexure member attached to a base of the heat sink and located between the base and an associated circuit board component. As the heat sink attaches to a circuit board carrying the circuit board component, the flexure member conforms to the surface of the circuit board component, thereby thermally contacting the circuit board component. The flexure member absorbs local tolerance differences on the circuit board component to provide a relatively uniform stress across the surface of the circuit board component. The flexure member further limits the amount of stress generated by the heat sink on the circuit board component. When used in conjunction with a heat sink spanning several circuit board components, the flexure member absorbs global tolerance differences among the circuit board components, thereby providing relatively uniform stresses to all of the circuit board components and limiting the amount of stress experienced by any one circuit board component.

    Abstract: A heat dissipation assembly (100) includes a retention frame (90), a heat sink (80), a fan holder (10), a pair of clips (60) and a fan (20). The heat sink is mounted on the retention frame and forms a pair of shoulders (822) at opposite sides thereof. The fan holder includes a fan duct (40) surrounding a top portion of the heat sink and including a pair of supports mounted on the shoulders, and a holding frame (30) detachably mounted on the fan duct. The clips are mounted on the supports and engaged with the retention frame. One side of the holding frame is pivotally engaged with the fan duct, an opposite side of the holding frame forms a latching leg (33) that is engaged with an ear (412) formed at the fan duct. Three catching arms extend from the holding frame and retain the fan in the holding frame.

  • Patent number: 6924980
    Abstract: A device for use in cooling a microelectronic component in a data processing system with a heat sink and a fan. The device includes means for maintaining the fan in close proximity to the heat sink and in a position relative to the fan for moving air over cooling surfaces of the heat sink and component to vibrationally isolate the fan from the heat sink and reduce the transmission of fan vibration to the heat sink. In one embodiment, the vibration isolation component is also configured to receive the fan and secure the fan in position relative to the heat sink to locate the fan in a predetermined position relative to the heat sink. In another embodiment, the vibration isolation component comprises a compliant gasket defining an opening adapted to receive an active area of the fan to allow air flow generated by the fan to reach the heat sink.

  • Patent number: 6920044
    Abstract: The present invention is related to an extendible and flexible heat-dissipation air conduit base as computer heat dissipation device. The invention mainly comprises an air conduit and fixtures. The air conduit is hollow and flexible with fixtures at both ends. Each fixture is in rectangle shape and connects with the air conduit through a circular hole. The fixture also has several positioning holes and through holes for metal wire to pass through and secure the air conduit with the fixture. By this design, the fixture at one end of the air conduit connects to a heat dissipation fan for CPU. Thus, it provides an excellent heat dissipation channel for computer CPU and helps to achieve the desirable heat dissipation effect.

  • Patent number: 6903931
    Abstract: An edge cooled graphite core aluminum cold plate for use in phased array radar systems, the cold plate including opposing aluminum skins, and a core layer sandwiched between the opposing aluminum skins. The core layer includes graphite surrounded by an aluminum body. The aluminum body includes inwardly directed tabs extending from opposing cooled edges of the cold plate, the inwardly directed aluminum tabs having orifices therethrough. The opposing aluminum skins also includes orifices therethrough aligned with the orifices in the tabs of the aluminum body to reduce the conductivity of the cooled edges of the cold plate thus reducing the temperature gradient between edge mounted heat sources and inwardly mounted heat sources without adversely affecting the structural integrity of the graphite core layer.

  • Patent number: 6899164
    Abstract: The present invention is a heat sink with guiding fins comprising a base with a plate part, wherein each side of a pair of two opposite sides of the plate part comprises a declining part; and two groups of fins expanded upwardly from each said declining part, wherein a channel whose top width is wider than its bottom width is form by the tow groups of fins and the base and there is a gap properly set between each two fins. By doing so, the heat sink can guide the flow generated by a fan to form a streamline with pressure and so obtains smaller wind resistance and better heat dissipation for the heat sink.
