New Microchip Fan: RSD5, Has No Moving Parts and is Soundless

Otherwise described as an electrostatic air propulsion with a corona discharge effect, this solid-state fan (RSD5), is the most powerful and energy efficient fan of its size. The device produces three times the flow rate of a typical small mechanical fan and is one-fourth the size. The technology has the power to cool a 25W chip with a device smaller than one cubic-cm and can someday be integrated into silicon to make self-cooling chips.

RSD5 incorporates a series of live wires that generate a micro-scale plasma (an ion-rich gas that has free electrons that conduct electricity. The wires lie within uncharged conducting plates that are contoured into half-cylindrical shapes to partially envelop the wires. Within the intense electric field that results, ions push neutral air molecules from the wire to the plate, generating a wind. The phenomenon is called corona wind.

The technology is a breakthrough in the design and development of semiconductors as it brings an elegant and cost effective solution to the heating problems that have plagued the industry and should thus change the cooling paradigm for mobile electronics.

Heck, what's this ?
