The working principle of the conventional gear oil heat dissipation system in the market at present is as follows: when the unit is started, the wheel box low-speed oil pump works; when the temperature of the gear oil is higher than 40 ℃, the gear box high-speed oil pump works; when the temperature of the oil in the gear box is higher than 55 ℃, the temperature control valve is closed, the radiator starts to work automatically, and lubricating oil enters the gear box after being cooled by the radiator; when the temperature of the gear oil is reduced to 4 ℃ and the temperature of the high-speed shaft bearing is lower than 65 ℃, the radiator automatically stops working, and lubricating oil directly enters a gear box through a temperature control valve to be forcedly lubricated; when the temperature of the gear oil is higher than 75 ℃, the fan is operated under a load limiting condition.
