[0023] The specific operation is as follows. When in use, the sealed inner cover 303 is fixed to the front side of the DC interface 4 and the AC interface 5 through the snap-in connection between the snap-in column 302 and the snap-in groove 301. The rubber sealing strip 304 can improve the sealing performance of the sealed inner cover 303 for protecting the DC interface 4 and the AC interface 5 to prevent water from entering the inside. Then the sealed outer cover 306 is covered on the front end of the protective box 2 so that the sealed outer cover 306 is snap-connected with the front end of the protective box 2 to strengthen the protection of the DC interface 4 and the AC interface 5. The elastic sealing layer 305 can not only make the connection between the sealed outer cover 306 and the protective box 2 tighter, but also improve the overall sealing and waterproof performance of the protective box 2.

The thermal silicone grease 701 can increase the heat dissipation speed of the containing box 1. The temperature inside the protective box 2 is monitored in real time through the temperature sensor 702. When the temperature is too high, the air conditioner 705 is started and the cold air is transported to the inside of the cooling chamber 703 through the cold air pipe 706, thereby lowering the containing box 1 to contact the cold air and reduce the temperature of the containing box 1.

[0026] Please refer to Figure 1 to Figure 2 A DC interface 4 is installed on the left side of the accommodating box 1, and an AC interface 5 is installed on the right side of the accommodating box 1.
