Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal chassis, in particular to a dustproof and heat-dissipating universal sheet metal chassis. Background Art

[0002] Universal sheet metal chassis is a metal shell used to protect computers or other electrical equipment. Its main function is to provide physical protection and heat dissipation. This type of chassis is usually made of sheet metal, that is, a product made of metal sheets through shearing, bending and other processing techniques. The design of the sheet metal chassis can prevent dust from entering the equipment, and can also help the equipment dissipate heat to ensure the normal operation of the equipment and extend its service life.

[0003] During long-term use, a large amount of dust and other impurities will accumulate on the surface of the dust net of a universal sheet metal chassis, affecting the normal heat dissipation of the chassis. However, the dust net of the existing chassis is not easy to disassemble and install, and it is not convenient to clean and replace the dust net. The existing sheet metal chassis generally sets heat dissipation holes on the side surface of the chassis for heat dissipation, but the heat dissipation effect of this method is average.
