NOVELTY - A modularized high power high frequency switch power supply structure, comprising a shell; the top part of the shell is fixedly connected with a top cover; two sides of the shell are provided with a round groove; the inner wall of the two round grooves are fixedly connected with a dust-proof net; the outer side of the two dust-proof net are rotatably connected with a rotating shaft; the surface of the rotating shaft is fixed with a driving blade; the inner side of the driving blade is fixedly connected with the brush hair; the surface of the brush hair and the outer contact of the dust-proof net, the top of the top cover is fixedly connected with a radiating fan. The utility model through the rotating shaft, a driving blade, brush hair, radiating fan, U-shaped pipe is set, convenient for cleaning the dust layer of the dust-proof net surface, preventing the dust layer accumulated on the dust-proof net, preventing the dust-proof net from blocking, further improving the radiating performance of the switch power supply; Through the graphene plate, radiating fin, radiating hole, branch pipe, transverse pipe, the air outlet hole is set, which is convenient for further increasing the radiating performance, which can improve the service life of the switch power supply.
