the other path of the water flows back to the engine through the electronic thermostat, the gearbox oil cooler, the engine oil cooler and the water pump;
In the adjustable mode:
The electronic thermostat can adjust the flow distribution among all branches and adapt to the heat management performance target under various conditions;
A degassing pipe is respectively connected from the radiator, the electronic thermostat and the engine to the expansion kettle.
The principle and the invention point of the invention are as follows:
1. the engine outlet adopts the electron temperature saver, and the cooling heating demand of each spare part is accurately satisfied:
The electronic thermostat is used for replacing a traditional wax thermostat, the opening of the electronic thermostat is controlled under different loads of an engine, and preheating and cooling requirements of the engine and a transmission under different environmental conditions and different working conditions are met.
2. the booster uses electric water pump to cool off, ensures that the booster normally works:
and an electric water pump is used for driving cooling liquid to cool the supercharger, so that the cooling requirements of the supercharger after large load and shutdown are met. Because the temperature of water coming out of the supercharger is higher under partial working conditions, the loop is connected to the expansion kettle, and the water is supplemented to the electric water pump from the expansion kettle and finally returned to the engine.
3. the loop where the fan heater is located is additionally provided with a valve to control the on-off of a water path, so that the performance of the fan heater of an engine is improved:
A valve is additionally arranged between the engine and the core body of the air heater, and the on-off of the valve is controlled according to requirements. Under the working condition that warm air does not need to be started, such as the cold starting working condition of the engine, the valve is closed at the moment, so that the heat loss on the loop is avoided, most of heat generated by the combustion of the engine is used for heating the engine, and the oil consumption of the whole vehicle can be reduced.
the invention has the beneficial effects that:
The electronic thermostat realizes reasonable distribution of heat of the engine and ensures the preheating and cooling requirements of the engine and the transmission under different conditions.
through increasing the valve on the warm braw return circuit, the switching of control valve had both guaranteed the needs of warm braw, also can promote the warm-up performance of engine, reduced whole car oil consumption.
the electric water pump is used for cooling, so that the normal work of the supercharger is ensured.
