Abstract
Electrostatic cooling apparatus with a needle emitter insulated along the shank thereof except for a sharp needle tip. The insulated needle emitter is supported along the axis of a funnel tube so as to augment the velocity of the ionic wind generated by the needle emitter. The needle emitter is axially adjusted within the funnel tube to tune the resonant cavity formed by the needle emitter and funnel tube to just below the space charge oscillation frequency.
