Description

Technical Field

[0001] This utility model relates to the field of computer technology, specifically to a computer dustproof chassis. Background Technology

[0002] The computer case is the housing for most of the computer's components. Sometimes, the term "computer case" is mistakenly used to refer to all internal components such as the central processing unit (CPU) and motherboard. A computer case generally includes the outer shell, brackets, and various switches and indicator lights on the front panel. As a computer accessory, its primary function is to house and secure these components, providing support and protection.

[0003] A computer chassis with announcement number CN220338039U is raised by placing the chassis on a fixed plate, connecting adjusting rods and support columns, and then limiting and fixing it with a surrounding plate to keep it away from the ground. This prevents ground moisture from entering the device, reduces the possibility of the device getting damp, prevents certain corrosion to the device, and ensures the normal operation of the internal components of the chassis.

[0004] There are some shortcomings in its use. When cooling the chassis, dust can enter the chassis through the ventilation holes, causing dust to adhere to the surface of the internal components, reducing the cooling effect of the internal components. At the same time, when dust enters the components, it can also cause poor contact, which limits the practicality of the chassis. Utility Model Content
