It includes a rectangular cabinet, a heat dissipation window recessed in the cabinet is provided on the back of the cabinet, and the heat dissipation window is provided with a heat dissipation window plate, which is parallel to the cabinet back plate, and a plurality of electrical installation boards are provided in the cabinet, which are parallel to the heat dissipation window plate, and a heat dissipation cavity is formed between the electrical installation board and the heat dissipation window plate. The utility model solves the technical problem that the heat dissipation of the power supply cabinet in the prior art requires heat dissipation equipment and high investment cost. The beneficial effect of the utility model is that the self-ignition heat dissipation of the power supply cabinet is combined with the auxiliary heat dissipation of the exhaust fan, and the heat from the front door and the back of the electrical installation board is dissipated at the same time, and the heat dissipation effect is good. The power supply cabinet is small in size, has few heat dissipation equipment, and reduces the manufacturing cost. The electrical appliances are installed vertically, which is convenient for heat dissipation and the power supply cabinet has good stability. Although this type of power supply cabinet has the effect of improving heat dissipation, it is lacking in the maintenance of the power supply cabinet. Since this type of power supply cabinet does not have a structure for auxiliary maintenance, when the maintenance personnel perform maintenance on the inside of the power supply cabinet, it is necessary to remove its internal components from the cabinet, which not only reduces the maintenance efficiency, but also causes damage to its internal components.
