ION WIND FAN DESIGNS

摘要

An ion wind fan can be made more resistant to electrical arcing by designing a supporting dielectric further from an emitter electrode, in one embodiment, such an ion wind fan according to one embodiment of the present invention has an emitter electrode and a collector electrode, and an isolator comprising a dielectric to provide electrical isolation for one or both of the emitter electrode and the collector electrode. In one embodiment, the isolator has a tapered sidewall so that the sidewall becomes thinner la the upstream direction over at least a portion of the sidewall. In one embodiment, the taper is a linear taper.
