    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.
