    摘要: A cold plate comprises a cold plate body having a base for thermally engaging a heat-generating device, a plurality of internal channels extending through the cold plate body for the passage of a liquid coolant, a first region between the base and the plurality of internal channels, and a second region between the plurality of internal channels and a top that is generally opposite the base from the plurality of internal channels. The cold plate body is made from a first thermally conductive material. The cold plate also comprises at least one thermally conductive member extending around the plurality of channels from the first region below the plurality of channels to the second region above the plurality of channels. The at least one thermally conductive member has a greater thermal conductivity than the first thermally conductive material to move heat from the first region to the second region.

    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: A heat sink comprises a first thermally conductive base having a first face to thermally engage a heat-generating electronic component and a second thermally conductive base with a plurality of fins on a first face and a second face to engage the first base. The fins on the second base are positionable in either of two orientations relative to the heat-generating electronic component to which the heat sink is coupled. The fins are selectively placed in the orientation that best utilizes the direction of air flow available to the heat sink. The orientable fins of the heat sink afford flexibility in arranging the heat-generating electronic component on a circuit board or in arranging a circuit board within a computer chassis.

    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.
