Further, the heat insulation section 802 is fixedly connected to any position of the top, the side and the bottom of the explosion-proof box 1. The heat pipes 8 are multiple and arranged in a row or a plurality of rows. The heat pipe 8 is a heat pipe having a straight pipe shape or a heat pipe having a special shape. The heat pipe with the special-shaped shape comprises any one of a heat pipe with a bent pipe shape and a heat pipe with a coil pipe shape. And a plurality of cooling fins 9 are uniformly and fixedly connected to the outer circle of the condensation section 803. The peripheral side surfaces of the outer cover shell 2 are provided with shutters 10. The outer cover shell 2 comprises a front cover 11, and a box door 12 is arranged on the front cover 11. The box door 12 is provided with an observation window 13 made of visual materials. The visual material comprises glass.
The structure provided by the application comprises an explosion-proof box body, a heat pipe, a radiating fin, an outer cover shell, a fastener and an electric element. The explosion-proof box body is located inside the outer cover shell, and the outer cover shell is connected with the explosion-proof box body through the fastening piece. The explosion-proof box body is provided with a base plate, the explosion-proof box body is divided into a front cavity and a rear cavity, and the electric element is positioned in the front cavity and fixed on the base plate.

And a plurality of cooling fins are uniformly arranged on the outer circle of the condensing section of the heat pipe and fixed on the condensing section of the heat pipe.
Based on the technical scheme, the method can also be as follows: the louver window is arranged on the side face of the periphery of the outer cover shell, so that air flow and heat dissipation in the cavity between the outer cover shell and the explosion-proof box body are facilitated. The front cover of the outer cover shell is provided with a box door for operating an operation button on the explosion-proof box body after being opened, and the box door is provided with glass or other visual materials for observing equipment such as a screen, an instrument and the like on the explosion-proof box body.

The heat generated by the electric elements in the explosion-proof case is discharged out of the case through the quick heat transfer property of the heat pipe phase change medium, so that the electric elements are prevented from being damaged due to overhigh temperature in the explosion-proof case. Meanwhile, the outer cover shell can prevent the explosion-proof box body from influencing heat dissipation due to overhigh surface temperature of the box caused by direct sunlight.
