Dust removal device

Abstract

The invention provides a dust remover. The dust remover comprises an installation frame, a positive static generator, a negative static generator, at least one positive electricity metal net and at least one negative electricity metal net, and the positive electricity metal nets and the negative electricity metal nets are arranged in the installation frame. The positive static generator is connected to the positive electricity metal nets and used for enabling the positive electricity metal nets to generate positive static. The negative static generator is connected to the negative electricity metal nets and used for enabling the negative electricity metal nets to generate negative static. The positive electricity metal nets and the negative electricity metal nets are used for adsorbing dust particles. The positive electricity metal nets and the negative electricity metal nets are alternately arranged in an overlapping mode, and each positive electricity metal net and the corresponding adjacent negative electricity metal net are arranged at an interval. According to the dust remover, by the adoption of a positive charge and negative charge alternate distribution structure, an electromagnetic field which influences electronic equipment is not generated, air motion is not impeded, and efficient cooling of the electronic equipment can be ensured. The invention further provides a cooling and dust removing system.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a dust removal device. Background technique [0002] Existing computer rooms of communication base stations and server rooms are usually equipped with fans for heat dissipation. The air flow caused by the cooling process of the fan will cause a large amount of dust to adhere to the inside of the electronic equipment in the equipment room. The dust will reduce the insulation resistance between adjacent printed lines, or even short circuit, affecting the normal operation of electronic components. [0003] The existing main dust removal methods include filter dust removal method and electrostatic dust removal method. The filter dust removal method mainly uses the filter principle to filter out the dust larger than the filter screen gap, the dust removal effect is poor, and the filter screen is easy to block. The electrostatic dust removal method mainly uses DC high volta...

AI Technical Summary

Problems solved by technology

The filter dust removal method mainly uses the filter principle to filter out the dust larger than the filter screen gap, the dust removal effect is poor, and the filter screen is easy to block

The electrostatic dust removal method mainly uses DC high voltage to ionize the air to generate a corona phenomenon, so that the dust is charged and moves to the dust collection pole under the action of the electric field force. Its dust removal efficiency is high, but the electric field generation device used in the electrostatic dust removal method Complex structure and bulky

And generally accompanied by a strong electromagnetic field, it may affect the normal operation of electronic equipment, so it is difficult to apply the dust removal device to existing electronic equipment
