When the second temperature sensor 102 of the engine 10 detects that the temperature of the cooling medium of the engine 10 exceeds the preset temperature parameter, the control module 22 opens the first valve 17, the cooling medium of the engine 10 flows into the cooling tank 13 through the cooling pipeline of the cooling tank 13, the cooling tank 13 cools the cooling medium and then flows into the radiator 11 again, at this time, the cooling fan 12 can work at a low rotation speed, and the rotation speed of the cooling fan 12 does not fluctuate. Similarly, when the first temperature sensor 142 detects that the temperature of the hydraulic oil exceeds the preset temperature parameter, the control module 22 controls the second valve 18 to open, the hydraulic oil flows through the cooling tank 13 to be cooled, the cooled hydraulic oil enters the radiator 11 again, at this time, the rotating speed of the cooling fan 12 can be kept low to work, and the rotating speed of the cooling fan 12 does not fluctuate. The hydraulic oil enters the cooling tank 13 through the hydraulic pump 15 and the hydraulic motor 16.
This application is through the temperature of the coolant who detects engine 10 and the temperature of hydraulic oil, when coolant's temperature or hydraulic oil temperature surpassed preset temperature parameter, control is opened first valve and second valve on engine outlet pipe or the hydraulic pressure pipe, let high temperature coolant or hydraulic oil flow through the cooling tank under the driver's cabin, utilize the second medium of cooling tank to cool down, coolant and hydraulic oil after the cooling down pass through the radiator, radiator fan can realize lower rotational speed operation, radiator fan radiation noise has been reduced, fan motor works at low rotational speed, the energy consumption has been reduced, fan motor reliability has also been improved simultaneously.
