NOVELTY - The utility model claims a curtain grid switch power supply device, comprising a power supply main body, one side of the power supply main body fixedly connected with with a back plate, one side of the water inlet ring and the drain ring far away from the power supply main respectively is provided with a water inlet valve and a drain valve, between the water inlet ring and the drain ring is provided with a cooling pipe; the bottom of the power supply main body is provided with a radiating hole, the radiating hole is rotatably connected with a dust-proof plate. The utility model passes through the back plate cooling pipe, the water inlet valve and the drain valve are matched with each other, one side of the power supply device is provided with a graphene material back plate, compared with the traditional aluminium alloy material, the heat conducting performance is better, the production cost is lower, at the same time, the outer part is provided with a circulating cooling water pipe, the water flow in the cooling pipe is introduced from the water inlet valve, discharging from the drain valve, which can greatly take away the heat generated by the power supply, so as to reduce the environment temperature in the power supply, delay aging of the power supply component, convenient for long time normal work of the power supply device, and improve the service life.
