The invention discloses a movable water-cooling and air-cooling all-in-one machine in the technical field of heat dissipation and cooling. The movable water-cooling and air-cooling all-in-one machinecomprises a machine body, wherein movable cover plates with the same structure are movably inserted into the tops of the left side and the right side of the machine body separately; a bearing plate isarranged at the top of a hydraulic rod; a fixed plate is arranged at the top of the bearing plate; water conveying pipes are arranged at the left side and the right side of a water pump; spray headsare uniformly arranged at the opposite sides of two groups of flow collection pipes from top to bottom; heat dissipation fins are uniformly arranged at the rear side of the machine body; and a heat dissipation fan is arranged in a shell body, and located at the rear sides of the heat dissipation fins. According to the machine, heat dissipation is carried out through the cooperation of water cooling and air cooling; the fixed plate adopting heat-conducting aluminum plates makes contact with a workpiece, so that the heat dissipated by the workpiece and the heat generated by the fixed plate can be rapidly absorbed; and cooling water is sprayed through the spray heads and makes contact with the fixed plate, so that the workpiece is uniformly cooled.
