Detailed Description

Fig. 1 is a schematic structural diagram of a cooling system for a vehicle according to an embodiment of the present invention, and only a part related to the embodiment of the present invention is shown for convenience of description.
The system comprises:
a high temperature cooling loop and a low temperature cooling loop, wherein;
the high temperature cooling circuit includes: the water outlet 1 of the engine water jacket and the water outlet 2 of the engine water jacket are respectively connected with a high-temperature radiator and a warm air core body through a three-way valve, the high-temperature radiator and the warm air core body are respectively connected with two water inlets of an electronic thermostat (when the electronic thermostat is in a closed state, only the connection with the high-temperature radiator is that the water inlets are in the closed state, and the water inlet connected with the warm air core body is in an open state), the water outlet of the electronic thermostat is connected with an inlet of a high-power electronic water pump, the water outlet of the high-power electronic water pump (the electronic water pump with the power of 600 w-1500 w) is connected with the water inlet of the engine water jacket, and the water outlet of the engine water;
the low temperature heat dissipation loop includes: the water outlet of the low-power electronic water pump is respectively connected with the water inlets of the air water cooler and the turbocharger through three-way valves, the water outlets of the air water cooler and the turbocharger are respectively connected with the water inlet of the low-temperature radiator through three-way valves, and the water outlet of the low-temperature radiator is respectively connected with the water inlet of the low-power electronic water pump;
in an embodiment of the present invention, the system further includes:
the expansion kettle is connected with the one-way valve 1 and the one-way valve 2 through a three-way valve, the one-way valve 1 is connected with a water inlet of the low-power electronic water pump, and the one-way valve 2 is connected with a water outlet of the high-temperature radiator.
In an embodiment of the present invention, the system further includes:
the engine degassing branch comprises a flow limiting valve 1, a water inlet of the flow limiting valve is connected with a water outlet 3 of an engine water jacket, and a water outlet of the flow limiting valve is connected with a water inlet of an expansion kettle; the high-temperature radiator degassing branch comprises a flow limiting valve 2, a water inlet of the flow limiting valve 2 is connected with the high-temperature radiator, and a water outlet of the high-temperature radiator degassing branch is connected with a water inlet of the expansion kettle.
In an embodiment of the present invention, the system further includes:
and the stepless electronic fan is arranged near the high-temperature radiator and the low-temperature radiator.
In the vehicle cold start-warm process: when the vehicle is in cold start operation, due to the fact that the water temperature of the engine is low, the high-power electronic water pump can be opened and closed intermittently, the operation time of the high-power electronic water pump is prolonged gradually along with the gradual rising of the water temperature of the engine, and the closing time period is shortened gradually. When the water temperature of the engine rises to a certain value, the high-power electronic water pump is started to operate all the time, and the output flow performance can be correspondingly adjusted and changed along with the load working condition of the engine. In the whole process, the flow provided by the high-power electronic water pump is as even as possible with the flow required by the heat dissipation of the engine water jacket, so that the engine can not be locally overheated, and the temperature rise rate of the engine can be accelerated.
When the engine is warmed, the valve of the electronic thermostat is closed, and the branch of the water outlet pipe of the high-temperature radiator and the cooling liquid in the expansion pot are prevented from participating in circulation, so that the cooling liquid (generally about 1.0-1.4L in volume) in the expansion pot does not supplement water to the high-temperature heat dissipation loop before the valve of the electronic thermostat is opened, and the volume of the cooling liquid participating in circulation in the warming process of the engine is reduced; meanwhile, two flow limiting valves (the flow limiting valve 1 and the flow limiting valve 2) are adopted to respectively limit the flow of an engine degassing branch and a high-temperature radiator degassing branch, so that the heat loss of the engine brought away by cooling liquid in an expansion kettle in the degassing process is greatly reduced, the principle and the structure have obvious effects of improving the temperature rise rate of the engine, namely, the oil consumption and the pollutant emission are reduced, and the system can be ensured to have a good degassing function.
In the process of cold starting and hot vehicle heating, the stepless electronic fan is in a closed state, the low-temperature cooling loop does not participate in circulation, the lower environmental temperature is enough to ensure that the requirement of the air inlet temperature is met, and when the rotating speed of the engine reaches the stage that the turbocharger starts to operate, the engine oil with the lower temperature can also meet the heat dissipation of the turbocharger. Only the engine oil cooler branch and the warm air core branch participate in circulation in the whole hot car process, the temperature rising speed of the cooling liquid in the front period of the hot car is higher than that of the engine oil, the cooling liquid heats the engine oil in the stage, the viscosity of the engine oil is reduced in an accelerating mode, the friction loss of moving parts of the engine is reduced, and the reduction of the oil consumption of the engine is facilitated. The branch circulation of the warm air core body is used for providing comfortable warm air for the interior of the automobile and ensuring the comfort of the interior of the automobile.
And in the stage of vehicle operation, namely the electronic thermostat is not opened, after the vehicle is heated, the water temperature of an engine does not reach the temperature range in which the electronic thermostat is opened, but the turbocharger starts to work, the ECU controls the low-power electronic water pump to start to operate, and the supercharging and air inlet low-temperature water-cooling circulation loop starts to work. The low-temperature radiator cools the water-air intercooler and the supercharger, so that the air inlet temperature of the engine meets the requirement. When the air inlet temperature is reduced by a certain value, the ECU controls the low-power electronic water pump to stop running, and the low-power electronic water pump can be circularly started or closed in the stage, so that the power economy performance of the engine is ensured, and the loss of electric quantity can be reduced. In this stage, the working state in the high-temperature cooling circulation loop is consistent with that of the engine when the engine is hot, only the engine oil cooler branch and the warm air core branch participate in circulation, and the engine needs to be heated as fast as possible because the engine does not reach the optimal working temperature range.
Vehicle operation-electronic thermostat open phase: along with the water temperature of the engine rising to the temperature range of the electronic thermostat opening, the ECU control unit adjusts the opening value of the electronic thermostat valve and the rotating speed of the high-power electronic water pump, and then the corresponding matching adjustment is carried out on the rotating speed of the PWM controlled stepless electronic fan, so that the water temperature of the engine is balanced in the corresponding optimal working temperature range under different loads and rotating speeds. Meanwhile, the ECU adjusts the rotating speed of the low-power electronic water pump to cool the pressurized gas and the supercharger. At this stage, all branches in the high-temperature cooling circulation loop and the low-temperature cooling loop can participate in circulation at the same time, and the temperature difference of dozens of degrees exists between cooling liquids in the high-temperature cooling loop and the low-temperature cooling loop, and the two cooling loops share one expansion pot for water supplement, but two one-way valves are adopted in the two pipelines of the water supplement branches, so that the high-temperature cooling loop and the low-temperature cooling loop are prevented from generating cross flow under a certain working condition. Through the precise cooperation of system-associated electronic components, the engine is guaranteed to exert the best dynamic property, economy, good emission and NVH under various working condition loads.
The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
