step two: when the humidity sensor (307) detects that the humidity in the cabinet body (2) is more than 50%, the circulating pump (402) operates to pump out the cooling liquid in the cooling liquid barrel (401), the cooling liquid flows into the cooling pipe (302) through the liquid outlet pipe (403), the temperature in the cooling pipe (302) is reduced, so that the moisture in the cabinet body (2) is condensed into water drops on the surface of the cooling pipe (302), the water drops flow into the water collecting tank (304) at the bottom end through the cooling pipe (302) and then are discharged from the water collecting tank (304), the cooling liquid flows into the liquid return pipe I (404) through the cooling pipe (302) and then flows into the condenser (405) through the liquid return pipe I (404), the radiator (406) operates to radiate the condenser (405), the radiated cooling liquid flows back into the cooling liquid barrel (401) through the liquid return pipe II (407), the circulation is performed, and the radiator (406) operates to suck hot air in the cabinet body (2) through the radiating air pipe (408) and then discharge pipe (408), the heat dissipation of the cabinet body (2) is convenient;
step three: when the humidity sensor (307) detects that the humidity in the cabinet body (2) is less than 50%, the circulating pump (402) is in a standby state, and the radiator (406) operates to suck hot air in the cabinet body (2) by the radiating air pipe (408) and then discharge the hot air, so that the heat dissipation of the cabinet body (2) is facilitated.
