[0002] The utility model patent with announcement number CN210985205U discloses an anti-condensation device for an electrical cabinet, including an electrical cabinet, a condensation structure and a water storage structure. The condensation structure is installed and fixed inside the electrical cabinet, and the water storage structure is movably connected to both sides of the outside of the electrical cabinet. The condensation structure includes a condensation plate, an exhaust strip, a heater and a condensation sheet. The condensation plate is fixedly installed at the middle and upper end inside the electrical cabinet, and the exhaust strip is opened on the lower surface of both sides of the electrical cabinet. The heater is fixedly installed at the center of the bottom of the electrical cabinet and is electrically connected to the power supply of the electrical cabinet. The condensation sheet is embedded and fixed on the inner side of the condensation plate and is electrically connected to the power supply of the electrical cabinet. In the device, a heater and a condensation plate are arranged, and the heater sublimates water vapor, so that the water vapor rises to the surface of the condensation plate to condense into water droplets and is collected. It is suitable for the production and use of anti-condensation devices for electrical cabinets. However, when the device is in use, the water droplets on the condensation plate flow down naturally. When the water vapor inside the device is too large, the water droplets condense quickly and drip naturally, causing the components to be damp and short-circuited. At the same time, the water vapor adhering to the outside of the cabinet is not easy to remove. Therefore, improvements are needed. Utility Model Content
