Noise-free heat dissipation shell of computer

The utility model relates to the technical field of computer shells, and discloses a computer noise-free heat dissipation shell which comprises a bottom plate, the front face of the bottom plate is fixedly connected with a panel, the back face of the bottom plate is fixedly connected with a back plate, the surface of the back plate is fixedly connected with a heat dissipation assembly, and the back face of the back plate is fixedly connected with a vacuum dustproof assembly. A right side plate is fixedly connected to one side of the bottom plate, and sliding grooves are formed in the symmetrical faces of the face plate and the back plate. According to the noise-free heat dissipation shell of the computer, through the arrangement of the vacuum dustproof assembly, an HEPA filter is inserted into an embedding hole, so that external dust is blocked outside a ventilation box, dust falling on the surface of a heat dissipation fan and even dust entering the shell are avoided, the heat dissipation efficiency is indir
