[0021] Based on the above implementation description, temperature sensor is arranged in the inside of box door 103 to monitor the temperature in the box body in real time and feedback to the liquid crystal screen outside the box door 103, the sensor group is also matched with single-chip microcomputer to start the element carried by cooling structure 2 according to the temperature threshold value of temperature sensor feedback to carry out automatic cooling;When temperature is too high, exhaust pipe 202 removes the heat in distribution box body 1, and the cold pipe network 303 of thermoelectric refrigeration piece 3 is located in cold air pipe 201, and cold air is blown into distribution box body 1 from cold air inlet 212 by air inlet fan 211, to directly reduce the temperature in distribution box body 1.

[0022] Please refer to the drawing of the specification Figures 2-3Two sets of air intake fans 211 are provided at the opening of the cold air duct 201, and their outlets are horizontally opened on the inner side of the cold air duct 201. Thermoelectric cooling element 3 is installed on the inner wall of the cold air duct 201 and the cold pipe network 303 is kept inside the cold air duct 201. A layer of dry cotton is embedded on the inner side of the cold air outlet 212 to absorb moisture.

The electrical guide rail 203 can be fixed in the installation area by fixing feet of different lengths. The working range of the cold air duct 201 corresponds exactly to the installation area. The bottom of the thermoelectric cooling element 3 has a drainage groove 301, and the end of the drainage groove 301 extends to the outside of the mounting base 102 through a pipe, which can discharge the moisture generated by the cold end of the thermoelectric cooling element 3 to the outside of the mounting base 102 through the drainage groove 301 and the pipe.

[0023] Appendix Figure 3 In the heat dissipation pipe 202, a transverse air intake V-groove 223 is provided on the inner side. A cross-flow fan 221 is installed on the inner side of the heat dissipation pipe 202, which is parallel to the air intake V-groove 223. An exhaust fan 224 is installed on the inner side of the tail groove 204. The exhaust fan 224 is embedded in the heat dissipation window 101 and is engaged with the heat dissipation window 101. The cross-flow fan 221 is horizontally placed in the heat dissipation pipe 202 and draws in the power distribution box 1 by rolling. At the same time, when the exhaust fan 224 is turned on, a negative pressure is formed between the heat dissipation pipe 202 and the power distribution box 1, which more effectively draws in the air from the power distribution box 1, thereby increasing the air flow speed and increasing the heat dissipation efficiency.

This is suitable for high-temperature working environments, while in daily use, heat dissipation can be achieved only through the heat exhaust pipe 202, thus being more energy-efficient and environmentally friendly. In addition, the components in the cooling duct 201 and the heat exhaust pipe 202, namely the intake fan 211, the cross-flow fan 221, the exhaust fan 224, and the thermoelectric cooling chip 3, are all connected in parallel and connected to the power distribution port.
