[0031] Working principle: When the humidity detector detects that the humidity in the outside air is lower than the set threshold, it transmits a signal to the controller, and the controller controls the first fan and the second fan to rotate forward for a period of time, so that the outside air returns to the outside through the first ventilation hole, the first moisture absorption frame, the first fan, the second fan, the second moisture absorption frame, and the second ventilation hole in turn. The absorbent cotton in the first moisture absorption frame absorbs the water vapor in the outside air to prevent the water vapor in the outside air from entering the switch cabinet. The airflow carrying the heat emitted by the internal components of the switch cabinet brings the moisture in the absorbent cotton in the second moisture absorption frame to the outside, thereby removing the moisture in the absorbent cotton in the second moisture absorption frame. Then the controller controls the first fan and the second fan to rotate in the opposite direction for a period of time, so that the outside air returns to the outside through the second ventilation hole, the second moisture absorption frame, the second fan, the first fan, the first moisture absorption frame, and the first ventilation hole in turn. The absorbent cotton in the second moisture absorption frame absorbs the water vapor in the outside air to prevent the water vapor in the outside air from entering the switch cabinet. The airflow carrying the heat emitted by the internal components of the switch cabinet brings the moisture in the water-absorbing cotton in the first moisture-absorbing frame to the outside, thereby removing the moisture in the water-absorbing cotton in the first moisture-absorbing frame.

[0032] After the above process, the controller controls the drive motor to rotate forward and reverse periodically, and the drive motor drives the first screw, the first bevel gear, the second bevel gear, the connecting rod, the third bevel gear, the fourth bevel gear, and the second screw to rotate forward and reverse periodically in sequence. The first screw drives the first fan to move up and down, and the second screw drives the second fan to move up and down, and the second fan moves at the same speed as the first fan, but in the opposite direction. At the same time, the controller controls the first fan and the second fan to rotate back and forth periodically, so that the direction of the airflow is periodically changed, so as to better dissipate heat inside the switch cabinet.
