The invention discloses an electrical cabinet and a heat dissipation control method thereof. The electric cabinet comprises a cabinet body, an electric heating element and a cooling system, wherein an evaporator and an evaporator fan of the cooling system are arranged on the upper part inside the cabinet body and are connected with each other through a wind cavity; the cabinet body comprises a separation mechanism for separating air inlet sides and air outlet sides of both the evaporator and the evaporator fan; the cabinet body comprises an air door A arranged on the lower part and an air door B arranged to correspond to the evaporator fan; the air doors A and B respectively comprise air inlets arranged on the wall of the cabinet body, door bodies for sealing the air inlets and operating mechanism for opening and closing the door bodies; one side of the door body B of the air door is rotationally connected to a wall plate of the cabinet body, and the door body B when being in an open state and the cabinet body structure form a channel communicated with the outside of the cabinet body; the heat dissipation control method comprises the step that a control unit generates or receives an air door-opening control signal, and sends a door-opening drive signal to each air door operating mechanism so as to drive each air door operating mechanism to open each air door in place. The electrical cabinet and the heat dissipation control method thereof overcome defects in the prior art, improve system safe operation reliability, reduce maintenance cost of the electric cabinet, and achieve a simple structure and reliable operation.
Description
technical field [0001] The invention relates to an electric cabinet integrated with a cooling system, and also relates to a method for controlling heat dissipation of the electric cabinet. Background technique [0002] Electrical cabinets (such as wind power converter cabinets, photovoltaic inverter cabinets, etc.) are widely used in communication, electric power, broadcasting and television systems, and have great market potential. In order to improve the adaptability to outdoor climate and environmental conditions, the existing electrical cabinets are usually equipped with dustproof and waterproof structures on the cabinet body; since most of the electrical cabinets are equipped with active heating equipment, in order to improve the heat dissipation effect, there has been a configuration in the electrical cabinet cabinet Refrigeration, heat exchangers, cooling fans, heaters and other temperature control and adjustment equipment to ensure the normal operation of your equipm...
