Novel computer hardware heat dissipation box

The invention discloses a novel computer hardware heat dissipation box. The box comprises a handle, fan blades, a motor mounting plate, a limiting ring, a convex block, a limiting frame, a first motor, a second motor, a second transmission shaft and a box body, an illuminating lamp is fixedly mounted on the top surface of the inner wall of the box body through a bolt; parts in the box body can beconveniently observed through the illuminating lamp; when internal parts of the box body need to be overhauled, the maintenance difficulty of workers can be reduced, the rubber pads are symmetricallyand fixedly installed at the two ends of the bottom face of the box body through glue, the box body is prevented from making contact with other parts of a computer through the rubber pads, and therefore when the parts in the box body work, noise can be effectively reduced, and the practicability of the heat dissipation box is improved; the heat dissipation opening of the computer box can be openedand closed, when heat diss
