Low-voltage electrical cabinet having circular heat-dissipation function

Abstract

The invention discloses a low-voltage electrical cabinet with the function of circulating heat dissipation, which comprises a cabinet body, a partition board is fixedly installed in the cabinet body, the partition board includes a horizontal plate, and the top and bottom of the horizontal plate are respectively fixedly connected with The first vertical plate and the second vertical plate, the horizontal plate and the first vertical plate are provided with air holes arranged equidistantly, the bottom of the cabinet is provided with a base, and a cooling chamber is provided in the base, and cooling Condensation pipes arranged at equal distances are arranged in the room, air delivery holes and exhaust holes are respectively arranged on the base, and fans are arranged at the bottom of the air delivery holes. The low-voltage electrical cabinet with the function of circulating heat dissipation can increase the air convection speed in the low-voltage electrical cabinet, and the heat dissipation speed is faster, so that the low-voltage electrical cabinet has a good circulating heat dissipation effect, and avoids excessive temperature in the cabinet. damage to electrical components, ensuring the reliability of the low-voltage power supply system.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a low-voltage electrical cabinet with the function of circulating heat dissipation. Background technique [0002] A low-voltage electrical appliance is a component or device that can switch, control, protect, detect, transform and adjust circuits or non-electrical objects by manually or automatically switching on and off circuits according to external signals and requirements. Control electrical appliances can be divided into high-voltage control electrical appliances and low-voltage control electrical appliances according to their working voltage, with AC 1200V and DC 1500V as the boundary. Generally speaking, low-voltage electrical appliances can be divided into two categories: power distribution appliances and control appliances, which are the basic components of complete sets of electrical equipment. In industry, agriculture, transportation, nationa...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many electrical components installed in low-voltage electrical cabinets, and the differences are large. Generally speaking, the ventilation and heat dissipation effect in the existing low-voltage electrical cabinets is poor. If the temperature in the low-voltage electrical cabinet is too high, it will cause damage to the electrical components in the cabinet. Will directly affect the reliability of the low-voltage power supply system
