Ionic wind generating device

Abstract

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 the surface of the electrode of the ionic wind generator to affect the integral heat-dissipating device of the device. The device integrates ionic wind, heat dissipation and dust removal, improves the cooling performance and the heat-dissipating mode on the premise of not changing the size and weight, and solves the problem of dust accumulation amount.

Description

technical field

[0001] The invention relates to an ion wind generating device, in particular to an ion wind generating device with simple structure, low power consumption, no noise and capable of removing dust. Background technique

[0002] As the geometric size of electronic devices continues to shrink, the heat flux per unit volume will be too high. In order to ensure the operational reliability of electronic devices and prolong their service life, research on heat sinks for electronic devices has become particularly important. In recent years, many scholars at home and abroad have carried out a lot of exploration on ion wind cooling technology. Ion wind heat dissipation technology is a new type of heat dissipation technology based on electrohydrodynamics. After the high-voltage electric field acts on the fluid medium, it causes the active movement of the fluid medium, thereby affecting the temperature field. It is an active enhanced heat dissipation technology. Compared...
