Explosion-proof electrical cabinet

Abstract

The invention discloses an explosion-proof electrical cabinet. The cabinet comprises a box body. Multiple groups of vent holes are formed in the inner wall of the box body. The number of the vent holes in each group is two. The two vent holes in the same group are coaxially arranged. A sealing plate is arranged in each vent hole. A plurality of L-shaped brackets are fixedly connected to the innerwall of the box body. The plurality of L-shaped brackets and the plurality of vent holes are arranged in a one-to-one correspondence manner. Guide rods are fixedly connected to the side, close to theL-shaped support, of the sealing plate, a supporting spring is fixedly connected between the L-shaped support and the sealing plate, an arc-shaped rod is fixedly connected between the two guide rods on the same axis, and an air pumping device is arranged on the outer side of the box body and can pump air into an inner cavity of the box body through a vent hole. Gas is injected into the pushed ventholes, passes through the inner cavity of the box body and then is exhausted through the opposite vent holes, and the components are mounted on the corresponding gas paths, so that the components needing to be cooled are subjected to centralized heat dissipation in a targeted manner, and the heat dissipation and cooling efficiency is high.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an explosion-proof electrical cabinet. Background technique [0002] The electrical cabinet is made of steel to protect the normal operation of the components. The materials for the electrical cabinet are generally divided into two types: hot-rolled steel plate and cold-rolled steel plate. Compared with hot-rolled steel plate, cold-rolled steel plate is softer and more suitable for electrical appliances. The production of cabinets, electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] The electrical cabinets of the prior art are generally provided with a plurality of electrical devices inside, and the electrical devices will generate a large amount of heat when they work.

AI Technical Summary

Problems solved by technology

[0003] The electrical cabinets of the prior art are generally provided with a plurality of electrical devices inside, and the electrical devices will generate a large amount of heat when they work. Generally, a cooling fan is used for cooling. On the one hand, the cooling fan makes the electrical cabinet directly communicate with the outside world. Moist air enters the box and causes damage to the device. On the other hand, the position of the cooling fan is relatively fixed, which is not convenient for targeted cooling of individual high-heat-generating devices, resulting in limited heat dissipation.
