The invention provides an electrical cabinet with heat dissipation and dehumidification functions, and relates to the technical field of electrical cabinets, the electrical cabinet comprises an electrical cabinet body, a
water storage box is fixedly connected in the electrical cabinet body, a separation box is fixedly connected to the upper surface of the
water storage box, a
cooling pipe is movably clamped to the inner wall of the electrical cabinet body, and a water pump is fixedly mounted on the inner wall of the electrical cabinet body; an air cylinder and a
backflow plate are fixedly installed on the upper surface of the electrical cabinet body, and under the action of gravity, liquid drops pass through a set of round holes, flow to a conical column along the lower surface of a splitter plate, then are gathered together and are discharged through a water outlet
pipe. According to the structure of the scheme, contact between air and the dehumidification material can be fully utilized, the dehumidification efficiency is improved, the flow direction of the air is changed through the baffle plates, the air forms a complex flow path in the
system, distribution is more uniform,
moisture in the air is effectively removed through the
fiber layer, and then the dry environment in the electrical cabinet can be kept.
