The invention discloses a computer disk bracket. The computer disk bracket includes an outer shell, an inner shell and a disk bracket body, wherein the outer shell is internally provided with the inner shell, damping springs are evenly arranged between the outer side wall of the inner shell and the inner side wall of the outer shell, and the inner shell is internally provided with the disk bracketbody; the end, away from the inner shell, of the disk bracket body is fixedly connected with a top plate, spherical joint convex blocks are fixed at both ends of the inner side of the top plate, andboth sides of the end, close to the top plate, of the outer shell are provided with positioning holes matched with the spherical joint convex blocks; the center of the top of the outer shell is provided with a heat absorption sheet, the portion, outside the heat absorption sheet, of the outer shell is provided with a heat dissipation box, and the top end of interior of the heat dissipation box isprovided with a heat dissipation fan. The computer disk bracket is externally provided with the heat dissipation fan, so that the whole disk bracket body is in a closed environment; therefore, it is effectively avoided that in the process of heat dissipation, dust enters into the disk bracket body, so that computer failure is avoided, and the service life of a computer is prolonged.
