  • Patent number: 9507391
    Abstract: A heat sink comprises a plurality of fins that may be positioned in a plurality of orientations relative to a heat-generating electronic component to which the heat sink is thermally coupled. A controller may be used to detect an elevated processor temperature and to activate a drive member to automatically adjust the orientation of fins on the heat sink. The fins may be moved and aligned with an air flow made over the heat sink. The adjustable-fin heat sink affords added flexibility in arranging a processor or other heat-generating electronic component on a circuit board. The orientation or position of the heat sink fins may also be automatically changed in response to a change in the air flow direction as manifested by a rise in the temperature of the heat sink or the heat-generating member.

  • Patent number: 8807204
    Abstract: A system for cooling a heat generating device comprises a heat sink and a plurality of ion emitter elements that form an electrohydrodynamic (EHD) air flow device. The heat sink has a base disposed in thermal communication with a heat generating device, such as a processor. A plurality of heat sink fins is coupled to electrical ground to form ion collectors. Ion emitter elements are disposed in a non-planar pattern along first ends of the plurality of fins so that each ion emitter element is equidistant from the first end of a nearest fin. A power supply applies an electrical potential between the plurality of ion emitter elements and the plurality of fins to induce a flow of ions that cause airflow across the heat sink. It is preferable to have at least three ion emitter elements that are equidistant from each fin of the heat sink.

  • Publication number: 20130153199
    Abstract: A system and method for cooling a heat-generating device. The system comprises a heat sink base for contacting the heat-generating device, and a plurality of heat sink fins extending from the heat sink base, wherein the fins provide airflow passages that are open along a top, a first side and a second side. An ionic air moving device is disposed along at least one side of the heat sink for moving air through the airflow passages, and a fan is mounted adjacent to the top of the fins for moving air through the airflow passages. A controller selectively controls the airflow through the heat sink using only the ionic device, only the fan, or both the ionic device and the fan. A user or a system component may instruct the controller to enter a performance mode, an energy efficiency mode, or an acoustic mode.

  • Patent number: 7957149
    Abstract: Apparatus for securing or retaining a heatsink. The heatsink retention apparatus includes a heatsink module that cooperates with first and second spring loaded latches secure to a circuit board on opposing sides of a heat-generating component. The heatsink module includes a handle pivotally secured to opposing sides of the heatsink body, and bails pivotally secured to the handle. In addition, the bails extend downward to dispose a lower bail member adjacent the spring loaded latches. As the handle pivots between a first position to raise the bails and a second position to lower the bails, the bails automatically move from a locked position to an unlocked position. Each of the spring loaded latches include a hook and at least one pre-loaded spring to transfer a minimum downforce to the lower bail members when the bails are raised. Accordingly, embodiments may be operated from the top of the heatsink without the use of tools, while providing a desired downforce over a range of heatsink heights.
