Power distribution cabinet with high heat dissipation performance

Abstract

The invention discloses a power distribution cabinet with high heat dissipation performance, which comprises a cabinet body, wherein the upper ends of the two sides of the cabinet body are both provided with heat dissipation fans, the air inlet ends of the two heat dissipation fans are both provided with air inlet pipes, the cabinet body is provided with ventilation mechanisms which are respectively positioned below the two heat dissipation fans, and each ventilation mechanism comprises a first fixing block and a second fixing block which are fixed on the inner wall of the cabinet body, and each second fixing block is located above the corresponding first fixing block. According to the power distribution cabinet, the structure is reasonable, the size of a first through hole and a second through hole can be automatically adjusted according to the temperature, so that the air inlet amount in the cabinet body can be adjusted, the heat dissipation effect on the cabinet body can be improved, and meanwhile, along with the increase of the temperature, the heat dissipation fans can work, so that more effective and efficient heat dissipation can be carried out in the cabinet body, a dustproof net can be automatically cleaned, manual cleaning is not needed, and the labor amount of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet with high heat dissipation performance. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] At present, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing power distribution cabinets have heat dissipation mechanisms, such as heat dissipation holes, heat dissipation fans, etc., but there are certain disadvantages. For example, if the heat dissipation is only through the heat dissipation holes, the heat dissipation effect may be insufficient, but the heat dissipation through the fans, When the temperature drops, the fan is still working, and there will be a waste of electric energy; if the fan can be controlled according to the actual situation, the waste of electric energy will be greatly reduced, so we have designed a power distribution with high heat dissipation performance Cabinet to solve the above problems
