The invention discloses a heat-dissipation dustproof moisture-removal computer rack used for industrial automation. The heat-dissipation dustproof moisture-removal computer rack comprises a sealing box shell, a computer fixing rack and a base, wherein the left side and the right side of the sealing box shell are respectively provided with a chute window; a first spindle is rotatably connected withthe sealing box shell through a through hole; the inner surfaces of the left side and the right side of the sealing box shell are respectively provided with a chute; the outer surface of the sealingbox shell is provided with a visual window; the upper surface of the left side of the base is provided with a water pump device; and the lower end of the base is provided with a plurality of universalwheels. Since the computer rack structure in a current market is too simple and heat dissipation, dust prevention and moisture removal are only singly applied, the device further optimizes an industrial computer and combines heat dissipation, dust prevention and moisture removal into a whole. The device has a relatively simple structure, can be fixed and moved and can rotate for multiple people in use, cost is saved, and space is saved.
