Explosion-proof cabinet and explosion-proof machine

Abstract

The invention provides an explosion-proof cabinet and an explosion-proof machine, and relates to the technical field of explosion-proof machines, the explosion-proof cabinet comprises a cabinet body, and a liquid cooling radiator is arranged on a cabinet door of the cabinet body; the liquid cooling radiator comprises a pipeline, two ends of the pipeline are respectively provided with a liquid inlet nozzle and a liquid outlet nozzle, the liquid inlet nozzle is used for connecting a liquid pump, and the liquid outlet nozzle is used for connecting a liquid discharge pipe. The interior of the cabinet is hollow and used for arranging the explosion-proof unit, the explosion-proof unit works to generate heat, the heat is dissipated through the liquid cooling radiator, and heat dissipation of the explosion-proof unit is achieved. The cooling liquid is pushed by the liquid pump to flow in the pipeline, the cooling liquid absorbing heat flows out of the pipeline, and the cooling liquid circularly flows in the closed pipeline, so that the purpose of cooling and heat dissipation of the explosion-proof unit is achieved, the explosion-proof unit can normally work at a safe operation temperature, and the working performance of the explosion-proof unit is further guaranteed; heat dissipation is carried out in a liquid cooling mode, arrangement is convenient, heat dissipation can be carried out as long as the pipeline arrives, large-area heat dissipation is achieved, the heat dissipation effect is improved, and heat dissipation is safe and reliable.

Description

technical field [0001] The application relates to the technical field of explosion-proof cabinets, in particular to an explosion-proof cabinet and an explosion-proof machine. Background technique [0002] With the continuous development of my country's industry and the increasing scale of production, explosion-proof cabinets are more and more widely used in areas with explosive dangerous gases or steam in the sites of dangerous industries such as petroleum, chemical industry, metallurgy, and oil fields (in the normal During operation, a place where an explosive gas atmosphere may occur) and Zone 2 (a place where an explosive gas atmosphere may not occur during normal operation). Explosion-proof cabinets are equipment for installing control system hardware components and electrical components (controllers, communication modules, IO cards, power supplies, cables, etc.). The heating components or high-power heating components inside the cabinet are densely installed. A lot of h...

AI Technical Summary

Problems solved by technology

[0003] The current explosion-proof cabinets mainly adopt two heat dissipation methods: ventilated and compensated. The ventilated positive pressure explosion-proof cabinet can take away the heat from the heating components or high-power heating components in the positive pressure shell, thereby effectively solving the problem of cabinet heat dissipation. However, its gas consumption is dozens or even hundreds of times that of the compensation type; the requirements of the working method of the compensation type positive pressure explosion-proof cabinet determine that the shell must have a better sealing structure than the ventilated positive pressure explosion-proof cabinet, so that the cabinet The cooling conditions of the worsening
