ENERGY-SAVING HEAT DISSIPATION DEVICE OF AUTOMATIC CONTROL CABINET FOR THERMAL POWER PLANT

An energy-saving heat dissipation device of an automatic control cabinet for a thermal power plant is provided according to the present application, which includes a cabinet body, where a heat dissipation opening is provided at each of two sides of the cabinet body, a heat dissipation mesh is embedded inside each of the heat dissipation openings, an upper exhaust opening is provided on a top surface of the cabinet body, a movable heat dissipation mechanism is provided outside each of the heat dissipation openings, and an upper exhaust mechanism is provided on the top surface of the cabinet body. According to the present application, when a position of a cooling fan is adjusted through the movable heat dissipation mechanism, a cleaning roller is driven to rotate, so that an outer surface of a dust-proof grille is automatically cleaned, avoiding an unsatisfactory heat dissipation effect caused by grille holes being covered by dust and then a subsequent air intake being affected, thereby improving the overall heat dissipation effect. When an internal temperature is too high, evaporation liquid in an evaporation box is converted from a liquid state to a gaseous state, so that a jacking column is pushed to rise and the heat inside the cabinet body is discharged from the top, thereby further improving the heat dissipation effect.
