Power cabinet air inlet and outlet structure and power cabinet

Abstract

The invention discloses a power cabinet air inlet and outlet structure and a power cabinet. The power cabinet air inlet and outlet structure comprises an air inlet box and an air outlet box. The air inlet box and the air outlet box are arranged inside the side door panel of the power cabinet. According to the invention, the structure has the advantages of small air resistance and high protection level; first and second water blocking plates are arranged in an air box body; water rushes in through the opening of the air box, and then is blocked by the second water blocking plate and the first water blocking plate; water cannot burst into the power cabinet; an enough opening is arranged between the second water blocking plate and the first water blocking plate; air smoothly goes out of the cabinet (or into the cabinet) through water blocking plate gaps inclined at an angle; the air inlet box and the air outlet box are arranged on the side wall of the power cabinet; in and out air are insulated by the water blocking plates arranged on a middle frame, so that cold air flows through a heating body through a specially arranged channel path, and then is discharged from the air box on the other side; and the power cabinet has the advantages of high protection level, adjustable air volume in the air inlet and low air resistance of air inlet and outlet channels.

Description

【Technical field】 [0001] The invention belongs to the field of outdoor power cabinets, and relates to a power cabinet air inlet and outlet structure and the power cabinet. 【Background technique】 [0002] In the power cabinet, since the internal power modules and devices themselves generate relatively large amounts of heat, and excessive temperature rise will reduce the effective transmission power of the power modules, or even shut down, it is necessary to efficiently discharge the heat out of the cabinet, otherwise the temperature rise will affect to the use of the product. At the same time, in the outdoor application environment, it is also required to be dustproof and rainproof, and some special structures must be used to improve the protection level, such as the inter-shaped louver structure (see figure 1 ), or a special rain-proof structure for opening modules (see figure 2 ). This kind of design, combined with the dust-proof net, can play a certain protective funct...

AI Technical Summary

Problems solved by technology

[0005] 1) The protection level of the power cabinet is not high

[0006] 2) There are power cabinets with high protection level, and the ventilation volume is relatively low

[0007] 3) The structure of the power cabinet is fixed, with low adjustability and low standardization, making it difficult to serialize products and reduce costs
