Wherein the hydraulic oil is fed into the cooling tank 13 after passing through the hydraulic pump 15 and the hydraulic motor 16.
According to the application, by detecting the temperature of the cooling medium and the temperature of the hydraulic oil of the engine 10, when the temperature of the cooling medium or the temperature of the hydraulic oil exceeds a preset temperature parameter, the first valve and the second valve on the water outlet pipe or the hydraulic pipe of the engine are controlled to be opened, so that the high-temperature cooling medium or the hydraulic oil flows through the cooling box below the cab, the second medium of the cooling box is utilized for cooling, the cooled cooling medium and the cooled hydraulic oil pass through the radiator, the radiator fan can realize lower-rotation-speed operation, the radiation noise of the radiator fan is reduced, the fan motor works at a low-rotation-speed, the energy consumption is reduced, and the reliability of the fan motor is also improved.
