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： A liquid-cooled computer memory system includes first and second blocks in fluid communication with a chilled liquid source. A plurality of spaced-apart heat transfer pipes extend along a system board between memory module sockets from the first manifold block to the second manifold block. The heat transfer pipes may be liquid flow pipes circulating the chilled liquid between the memory module sockets. Alternatively, the heat transfer pipes may be closed heat pipes that conduct heat from the memory modules to the liquid-cooled blocks. A separate heat spreader is provided to thermally bridge each memory module to the adjacent heat transfer pipes.
