The sealing plate is provided to achieve sealing at the inspection port. The sealing plate and the shell are fixed by locking bolts. The first sealing ring installed on the sealing plate is pressed against the shell to prevent moisture from entering the shell through the inspection port. In the initial state, the sealing plate is located in the heat dissipation port, and the second sealing ring seals the heat dissipation port. The temperature sensor monitors the internal temperature of the shell and sends the monitoring signal to the microcontroller.
