Problems solved by technology

[0003] The circuit board will generate a lot of heat during operation. To ensure the normal operation of the circuit board, high-end equipment must be equipped with circuit board heat dissipation components to ensure long-term operation of the equipment. The common heat dissipation methods of the circuit board are nothing more than water cooling and air cooling. As far as the air-cooling method is concerned, the air-cooled heat dissipation is uniform heat dissipation, and the heat generation of different components on the circuit board is different, which will not only cause waste of wind energy, but also cause local overheating of the circuit board, which seriously affects the circuit board. In addition, the wind power of air cooling is relatively slow, which can easily cause dust to fall on the surface of the circuit board, which will seriously cause short circuit damage to the circuit board. The existing equipment lacks a corresponding dust removal structure, and it is difficult to ensure the safe operation of high-end equipment.
