How to solve the heat dissipation problem of explosion-proof distribution box

Heat dissipation problem of explosion-proof distribution box Since all components of explosion-proof distribution box are installed in explosion-proof explosion-proof cavity, air cannot flow, and heat dissipation problem has become the key problem to be solved by explosion-proof distribution box
.

Here we have adopted a new cooling technology - heat pipe cooling technology
.

(1) Principle of heat pipe technology A heat pipe is a heat transfer element with extremely high thermal conductivity.
It transfers heat through the evaporation and condensation of the working fluid in a fully enclosed vacuum tube.
It has extremely high thermal conductivity, good isothermal, cold The heat transfer area on both sides of the heat can be arbitrarily changed, long-distance heat transfer, temperature control 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) Structural layout of the inverter 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, and the outer wall of the explosion-proof casing is welded.
The trough radiator, the excess radiator and the trough radiator are connected by heat pipes
.

The heat generated inside the inverter is dissipated through the trough radiator of the excessive radiator heat pipe on the rear wall of the explosion-proof cavity
