Explosion-proof heat dissipation protection cabinet of PLC device

Abstract

The utility model provides a kind of explosion-proof heat dissipation protection machine case of PLC equipment belongs to equipment machine case technical field.The explosion-proof heat dissipation protection machine case of PLC equipment includes outer box main part and inner box main part.Box door is installed in box door front side, and heat dissipation fan is installed in installation mouth inside.Heat pipe spare is located in outer box shell inside, and ventilation gap is left between outer box shell inner wall and inner box shell outer wall, and fin is arranged in inner box shell outside, and heat pipe spare is connected with fin by penetrating inner box shell side wall.Heat dissipation fan operation makes the gap between inner box shell and outer box shell produce air flow, and the heat of heat pipe spare part between inner box shell and outer box shell is rapidly cooled and taken out by fast circulating air, realizes that inner box shell internal space temperature rapidly drops, ensure that the electronic equipment component in inner box shell inside can be at suitable operating temperature, and the electronic equipment component in inner box shell inside can realize the effect of continuous efficient cooling.
