Ionic wind generating device

The invention discloses an ionic wind generating device which comprises an ionic wind generator, a heat sink, a dust collector and a dustproof hood, wherein the ionic wind generator uses a needle-shaped emitter and a netty receiver; the ionic wind generator and the heat sink are designed in an integrated structure; the point of the needle-shaped emitter points to the middle between two adjacent heat-dissipating fins; an MnO2 catalyst coating is smeared to each of the heat-dissipating fins; a graphene heat-conducting adhesive compound coating is smeared to the surface of a heat conducting substrate; the ionic wind generator generates charged ions during operation to adsorb dust; the dust collector arranged on the outer side of the heat sink comprises a dust collecting plate, a dust collecting port and a dust collecting box to prevent dust adsorbed by the charged ions to cover an electronic apparatus. The dustproof hood is additionally arranged on the ionic wind generator to prevent dustfrom being adsorbed to t
