[0002] As a part of computer accessories, the computer case mainly plays the role of placing and fixing various computer accessories, and supporting and protecting them. In addition, the computer case also plays the important role of shielding electromagnetic radiation. Since computer accessories use a large number of integrated circuits, which are prone to high temperatures when running, high temperatures will not only cause unstable system operation and shorten service life, but may even cause some components to burn out. The heat that causes high temperatures comes from inside the computer accessories. Therefore, in order to ensure the service life and use effect of computer accessories, computer accessories are generally equipped with heat dissipation functions to take away the heat generated inside the computer accessories.
