The heat dissipation solutions for explosion-proof distribution boxes are as follows:

Explosion-proof distribution box heat dissipation problem Because all the components of the explosion-proof distribution box are installed in the explosion-proof cavity, the air cannot flow, and the heat dissipation problem has become a key problem to be solved by the explosion-proof distribution box. Here we have adopted a new heat dissipation technology-heat pipe heat dissipation technology.

1. Isothermal, heat transfer area on both sides of cold and heat can be changed arbitrarily, heat can be transferred over a long distance, temperature can be controlled, and a series of advantages. The heat exchanger composed of heat pipes has the advantages of high heat transfer efficiency, compact structure, and small fluid resistance loss.

2. Inverter structure layout We design the main circuit as a large unit, which is installed on the rear wall of the rectangular explosion-proof cavity. The rear wall is connected with heating elements such as IGBT modules and rectifier modules through an excessive radiator. Welding grooves are added to the outer wall of the explosion-proof enclosure. Radiator, the transition radiator and the trough radiator are connected by heat pipes. The heat generated inside the inverter is dissipated through the heat pipe groove-shaped radiator of the heat pipe on the back wall of the explosion-proof cavity.

Scope of application of explosion-proof distribution box:

Suitable for zone 1 and zone 2 of explosive gas environment;

Suitable for flammable dust environment in zone 21 and zone 22;

Suitable for the selection of IIA, IIB, IIC grade products;

Suitable for environments where the temperature group is T1-T6/T4;

Applicable to explosive and dangerous environments such as petroleum extraction, storage, chemical industry, medicine, military industry and military facilities;

2. Product features of explosion-proof distribution box:
