Power distribution cabinet heat-dissipation and dustproof device

Abstract

The application discloses a heat dissipation and dustproof device for a power distribution cabinet. The heat dissipation and dustproof device of the power distribution cabinet includes a box body of the power distribution cabinet, a cooling fan and a dustproof device. The wall of the box body of the power distribution cabinet is provided with an air inlet and an air outlet. The hot air in the power distribution cabinet flows upwards and flows out through the air outlet, and the external cold air enters through the air inlet to form a circulation of cold and hot air, which is more conducive to heat dissipation. The dust-proof device is composed of a mounting plate, filter cotton and a gland. The heat dissipation fan and the mounting plate are installed on both sides of the air outlet through flat head screws. The heat dissipation fan accelerates the flow of hot air. The plate has a conical countersunk hole, and the flat-head screw is flush with the plane of the mounting plate after tightening; the filter cotton is placed in the gland, and the filter cotton can be very effective in dustproof, and the gland is installed with the mounting plate through the bayonet on the mounting plate described above. The dustproof device is similarly installed at the air inlet. The dust-proof device can be disassembled and assembled by hand, which is convenient for cleaning.

Description

technical field [0001] The application relates to a power distribution cabinet, in particular to a heat dissipation and dust-proof device for a power distribution cabinet. Background technique [0002] Dustproof of the power distribution cabinet: Dustproof is something that must be paid attention to during the use of the power distribution cabinet. Dust accumulated in the power distribution cabinet for a long time will enter the interior of the power distribution cabinet, and eventually the dust will enter various line connectors and circuit boards, causing The poor contact of the line will affect the use of the power distribution cabinet. In addition, long-term accumulation of dust in the power distribution cabinet will greatly reduce the heat dissipation function, causing the fan and other components to fail to operate normally, resulting in a certain amount of noise. Therefore, certain dust-proof measures need to be taken in the use of power distribution cabinets. [00...

AI Technical Summary

Problems solved by technology

Such heat dissipation effect is not ideal, and there is basically no dustproof effect

Or use a fence-type dust-proof method, which is equipped with a cooling fan, but the fence is welded by metal, the cost is high, and it cannot be completely dust-proof

[0005] When using the traditional heat dissipation and dustproof device, it is no problem to completely prevent dust and the heat dissipation effect is not ideal, which will easily lead to abnormal wiring in the power distribution cabinet, thus affecting normal work

So this device is unreasonable and needs improvement
