摘要： 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.

摘要： An air moving apparatus includes an axial fan and an electrostatic device. The axial fan has a rotatable shaft defining a central axis of the axial fan, a plurality of blades secured to the shaft, and an air inlet opening. The electrostatic device is disposed immediately upstream of the air inlet opening of the axial fan, and includes a collector and an emitter. In one embodiment, the electrostatic device includes a cylindrical collector coupled to ground and has a central axis aligned with the central axis of the axial fan. The electrostatic device further includes a plurality of emitter wires coupled to a terminal of a direct current source and extending lengthwise within the cylindrical collector. During operation of the axial fan, the application of an electrical potential between an emitter and a collector causes ionic air movement radially outwardly away from a central axis of the axial fan.

摘要： A heat sink to remove heat from a processor within a chassis to air moving through a fin structure on the heat sink. An embodiment of the heat sink comprises a heat bus engaging the processor to conduct heat from the processor to a fin structure having interconnected, repeating cellular air channels. A U-shaped heat bus comprises a base and first and second legs extending therefrom connected to opposite sides of the fin structure. An embodiment of the heat bus has a solid conductive core to conductively transfer heat from the processor through the base and the first and second legs to sides of the fin structure. Alternately, an embodiment of the heat bus has a hollow core containing a fluid to evaporatively transfer heat from the processor through the base and the first and second legs to sides of the fin structure.

摘要： 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.
