The outside air passes through the dustproof net 15 and enters the air inlet slot. The fan blade 14 is driven by the motor 13 to rotate, so that the air in the air inlet slot passes through the second drying box 10 and enters the wiring slot. The air entering the wiring slot is freed of water vapor, and the air in the wiring slot flows from the lower end of the barrier frame 6 through the first drying box 8 to the outside. The activated carbon inside the first drying box 8 can prevent water vapor from entering the wiring slot from the lower end of the cabinet 1. The air circulates from the outside, the air inlet slot and the wiring slot, which can play a role in heat dissipation. At the same time, the air inlet slot is used as a buffer to prevent external dust from entering the wiring slot. When the electrical control cabinet is working, the components in the cabinet 1 will generate a lot of heat. The heat makes the rubber material in the electrical control cabinet emit a pungent smell. Activated carbon is a high-efficiency adsorption material with a strong adsorption capacity. It can purify the environment inside the cabinet 1. Activated carbon can absorb the odor emitted by the rubber material and reduce the inconvenience caused by the odor to the staff.
