US Patent 7830643 Power supply with electrostatic cooling fan

A power supply having an electrostatic circuit producing sufficient ionic motion to move ambient air over heated surfaces. The electrostatic circuit creates a corona discharge from several emitter point sources producing sufficient ionic motion to move ambient air over a hot surface, such as a heatsink or heatfins, which surface is in communication with the power supply housing. A high DC voltage is generated within the power supply when the power supply is energized to create the ionic motion.
