Description

Outdoor air-cooled heat-dissipation power distribution cabinet

Technical Field

The utility model relates to a switch board, in particular to outdoor air-cooled heat dissipation switch board.

Background

The distribution cabinet is a final-stage device of a distribution system. The power distribution cabinet is a general name of a motor control center. The power distribution cabinet is used in the occasions with dispersed loads and less loops; the motor control center is used for occasions with concentrated loads and more loops. They distribute the power of a certain circuit of the upper-level distribution equipment to the nearby loads. This level of equipment reply load provide protection, supervision and control, and when the switch board was used in the open air, because its expose outside easily influenced by external environment temperature, its internal temperature often can be higher, consequently need install heat abstractor additional to it.

Like a novel switch board of publication No. CN208797376U, it adopts the fan to dispel the heat to its inside, but its inside air flow is inefficient, and the heat dissipation is slow, and dustproof effect is not good.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an outdoor air-cooled heat dissipation switch board solves one or more in the above-mentioned problem.

The utility model provides an outdoor forced air cooling heat dissipation switch board, includes first side, second side, its characterized in that still includes:

the air outlet is positioned at the upper half part of the first side surface, and a heat dissipation fan is arranged at the air outlet;

the third side surface is positioned below the second side surface, the third side surface inclines inwards, an included angle is formed between the second side surface and the third side surface, and the included angle is 5-10 degrees;

the air inlet is located on the third side face, and an HEPA filter screen is installed at the air inlet.

Outside air enters from the air inlet and is discharged from the air outlet, the positions of the two air ports are matched with each other to form an air channel, heat inside the case is taken away, and the air inlet is inclined inwards to prevent rainwater from entering.

In some embodiments, the outlet has at least two openings, and the openings have masks thereon, and the openings are parallel to each other.

The shade is used for preventing rain.

In some embodiments, the third side surface is densely distributed with small holes, and the diameter of the small holes is 0.5-1 mm.

And large particle dust at the air inlet is removed.

In some embodiments, the HEPA filter further comprises at least two mounting bars, the mounting bars are mounted on the second side surface, the HEPA filter screen is mounted on the mounting bars, all the mounting bars are located on the same plane, the mounting bars are parallel to each other, and the plane formed by the mounting bars is parallel to the third side surface.

Let HEPA filter screen and air intake parallel, promote purifying effect.

Has the advantages that:

this device forms one through the business turn over wind gap of two upper and lower dislocation and can be covered with the inside wind channel of switch board, has consequently reduced the inside phenomenon of piling up heat of switch board, and consequently the air current speed of flow accelerates, and the radiating efficiency uprises.

From the aperture air inlet on the third side, can carry out the first filtration to the air, the large granule dust among the de aeration gets into the inside air of switch board and passes through the HEPA filter screen again, gets rid of less dust, and double-deck dustproof effectual that filters.
