[0029] Reference is made below Figure 1 The cooling system 100 according to the embodiments of the utility model is described below. By adding the liquid supplementing flow path 4 in the cooling system 100, the liquid supplementing flow path 4 can supplement liquid towards the radiator 3 and the flow path where the thermostat 2 is located, thereby facilitating the increase of the flow of the cooling liquid flowing into the radiator 3. As a result, the system circulation flow and the cooling liquid flow of the radiator 3 can be increased, the heat dissipation efficiency can be improved, and the pressure loss of the cooling system 100 can be reduced.

[0030] As Figure 1 shown, the cooling system 100 according to the embodiments of the utility model comprises an engine water jacket 1, a thermostat 2, a radiator 3 and a liquid supplementing flow path 4.

[0031] The engine water jacket 1 is provided with a water return port 11 and a cylinder head first water outlet 12. It is necessary to explain that the engine water jacket 1 comprises a cylinder head water jacket and a cylinder body water jacket, and the cylinder head water jacket and the cylinder body water jacket are communicated. The cylinder head first water outlet 12 can be arranged on the cylinder head water jacket. The water return port 11 and the cylinder head first water outlet 12 are communicated, that is, a part of the water flowing into the engine water jacket 1 at the water return port 11 can flow out from the cylinder head first water outlet 12, and the cooling liquid flowing out at the cylinder head first water outlet 12 can also flow back to the engine water jacket 1 through each component after flowing through the components, thereby completing the fluid circulation and providing effective cooling effect in the circulation process, so as to ensure that the automobile engine and each part work at a suitable temperature.

[0032] A part of the water at the cylinder head first water outlet 12 is suitable for flowing back to the water return port 11 after sequentially passing through the thermostat 2 and the radiator 3, that is, the cooling system 100 is provided with the thermostat 2 and the radiator 3. During the cooling process of the engine, a part of the cooling liquid in the engine water jacket 1 flows into the thermostat 2 from the cylinder head first water outlet 12, is cooled by the radiator 3, and then flows back to the engine water jacket 1 from the water return port 11. The thermostat 2 is arranged to effectively control the flow of the cooling liquid, so as to flexibly switch the flow of the cooling liquid flowing into the radiator 3 from the cylinder head first water outlet 12, and further flexibly adjust the heat dissipation efficiency of the radiator 3.

[0033] The component cooler 41 is arranged in the liquid supplementing flow path 4, the inlet end of the liquid supplementing flow path 4 is connected between the radiator 3 and the backwater port 11, and the outlet end of the liquid supplementing flow path 4 is communicated to the thermostat 2. That is, after the engine water jacket 1 is communicated to the thermostat 2 and the radiator 3, the liquid supplementing flow path 4 and the engine water jacket 1 are arranged in parallel.

[0034] Therefore, the cooling liquid flowing through the radiator 3 is partially flowed into the engine water jacket 1 through the backwater port 11, and the other part is flowed into the component cooler 41. The part of the cooling liquid is mixed with the cooling liquid flowed out of the first water outlet of the cylinder head 12 and then is jointly flowed into the thermostat 2. By distributing the cooling liquid into the radiator 3, the cooling liquid in the liquid supplementing flow path 4 and the cooling liquid in the engine water jacket 1 are flowed in parallel, so as to reduce the system pressure loss, increase the circulating flow of the cooling liquid into the radiator 3, and improve the heat dissipation efficiency of the radiator 3.

[0035] In addition, it is to be noted that the outlet end of the liquid supplementing flow path 4 can be directly connected to the thermostat 2, or can be communicated to the flow path into the thermostat 2 and then into the thermostat 2, so that the cooling liquid in the liquid supplementing flow path 4 is flowed into the thermostat 2 and then into the radiator 3 after passing through the thermostat 2, so as to increase the flow of the cooling liquid in the radiator 3. The outlet end of the liquid supplementing flow path 4 can be directly connected to the thermostat 2 by arranging a baffle, a flow dividing structure or other structures in the thermostat 2, so that the cooling liquid in the liquid supplementing flow path 4 and the cooling liquid at the first water outlet of the cylinder head 12 are mixed after being flowed into the thermostat 2, so as to avoid the cooling liquid directly flushing the thermostat wax package, and ensure the structural stability of the thermostat 2.

[0036] According to the cooling system 100 of the embodiment of the present application, the liquid supplementing flow path 4 is arranged, and the liquid supplementing flow path 4 is arranged in parallel with the engine water jacket 1, so that the cooling liquid in the liquid supplementing flow path 4 and the cooling liquid at the first water outlet of the cylinder head 12 are both flowed to the radiator 3 after being flowed into the thermostat 2, which is beneficial to increase the system circulating flow and the cooling liquid flow of the radiator 3, improve the heat dissipation efficiency, and reduce the pressure loss of the cooling system 100.

[0037] In some embodiments, the cooling system 100 further comprises a backwater pump 5, the backwater pump 5 is used for pumping water to the backwater port 11, the inlet end of the liquid supplementing flow path 4 is connected between the backwater pump 5 and the backwater port 11, and the outlet end of the radiator 3 is communicated to the inlet end of the backwater pump 5. In this way, the backwater pump 5 can pump the cooling liquid from the radiator 3 to the engine water jacket 1 and the liquid supplementing flow path 4, absorb heat and then deliver the high-temperature cooling liquid back to the radiator 3 for cooling, so as to realize the fluid circulation in the cooling system 100 and provide effective cooling.

[0038] In some embodiments, the cooling system 100 further comprises a backwater pump 5, the backwater pump 5 is used for pumping water to the backwater port 11, the inlet end of the liquid supplementing flow path 4 is connected between the backwater pump 5 and the backwater port 11, and the outlet end of the radiator 3 is communicated to the inlet end of the backwater pump 5. In this way, the backwater pump 5 can pump the cooling liquid from the radiator 3 to the engine water jacket 1 and the liquid supplementing flow path 4, absorb heat and then deliver the high-temperature cooling liquid back to the radiator 3 for cooling, so as to realize the fluid circulation in the cooling system 100 and provide effective cooling. Figure 1As shown, the inlet end of the return water pump 5 is communicated with the radiator 3, and the outlet end of the return water pump 5 is communicated with the inlet end of the liquid increasing flow path 4 and the return water port 11 of the engine water jacket 1 respectively, so that the return water pump 5 can accelerate the cooling liquid flowing out of the radiator 3, and a part of the accelerated cooling liquid can quickly flow through the component cooler 41 in the liquid increasing flow path 4 to absorb heat, and another part of the accelerated cooling liquid can quickly enter the engine water jacket 1 to cool the engine, so that the pressure provided by the return water pump 5 can act on the main circulation of the engine water jacket 1 and the flow of the liquid increasing flow path 4 at the same time, effectively improving the circulation power of the cooling system 100 and ensuring that the cooling system 100 continuously circulates.

[0039] In some embodiments, the thermostat 2 is provided with a first water inlet 21, a second water inlet 22 and a first water outlet 23, the first water inlet 21 is communicated with the cylinder head first water outlet 12, and the first water outlet 23 is communicated with the inlet end of the radiator 3, that is, when the cooling system 100 is working, the cooling liquid at the cylinder head first water outlet 12 can enter the thermostat 2 through the first water inlet 21 and flow to the radiator 3 from the first water outlet 23, so that the thermostat 2 can control the flow rate of the fluid flowing into the radiator 3, so that the cooling system 100 can effectively dissipate heat through the radiator 3 when overheating.

[0040] As shown, Figure 1 When the temperature of the engine reaches the opening temperature of the thermostat 2, the valve of the thermostat 2 opens to allow the cooling liquid to flow into the radiator 3 for heat dissipation, and as the temperature rises, the valve gradually opens until it is fully open, and the flow rate of the cooling liquid flowing into the radiator 3 gradually increases, and the heat dissipation efficiency gradually increases, so that the thermostat 2 controls the temperature of the cooling liquid within a suitable range by controlling the opening degree of the valve.

[0041] In addition, the outlet end of the liquid increasing flow path 4 is communicated between the first water inlet 21 and the cylinder head first water outlet 12, that is, the cooling liquid in the liquid increasing flow path 4 and the cooling liquid flowing out of the cylinder head first water outlet 12 in the engine water jacket 1 are mixed between the first water inlet 21 and the cylinder head first water outlet 12, and then flow into the thermostat 2, thereby enhancing the pressure of the fluid in the thermostat 2, and when the cooling liquid flows into the radiator 3 from the thermostat 2, the flow rate of the fluid flowing through the radiator 3 increases due to the pressure, and the flow rate increases, thereby enhancing the heat dissipation efficiency of the radiator 3.

[0042] The engine water jacket 1 is further provided with a cylinder body water outlet 13, which can be arranged in the cylinder body water jacket, that is, the cylinder body water outlet 13 and the cylinder head first water outlet 12 are both used for water outlet of the engine water jacket 1, and the cylinder body water outlet 13 is communicated with the second water inlet 22. That is, part of the cooling liquid in the engine water jacket 1 can directly flow into the thermostat 2, so that the thermostat 2 is directly contacted with the cooling liquid and judges the temperature information, thereby automatically adjusting the flow and flow path of the fluid delivered into the radiator 3 according to the temperature of the cooling liquid, controlling the heat dissipation efficiency of the radiator 3, and ensuring that the engine works in a suitable temperature range.

[0043] Therefore, the cooling liquid at the cylinder body water outlet 13 can also enter the radiator 3 through the thermostat 2, which is beneficial to increase the flow of the cooling liquid in the radiator 3 and enhance the heat dissipation efficiency.

[0044] In some embodiments, the cooling system 100 further comprises an oil cooler 6, and the thermostat 2 is further provided with a second water outlet 24, the inlet end of the oil cooler 6 is communicated with the second water outlet 24, and the outlet end of the oil cooler 6 is communicated with the inlet end of the water return pump 5. That is, the cooling system 100 is provided with the oil cooler 6 communicated with the thermostat 2, which can reduce the temperature of the oil. Wherein, after the cylinder body water outlet 13, the cylinder head first water outlet 12 and the liquid increasing flow path 4 are arranged to supply water to the thermostat 2 together, the total amount of the cooling liquid in the thermostat 2 is increased, thereby the flow of the cooling liquid flowing through the radiator 3 is increased, and at the same time, the flow of the fluid flowing through the oil cooler 6 is also increased synchronously, and the oil cooling efficiency is improved.

[0045] Specifically, as shown in Figure 1 the oil cooler 6 is connected in parallel with the radiator 3, the thermostat 2 is provided with two outlet ends communicated with the oil cooler 6 and the radiator 3 respectively, so that the thermostat 2 can control the flow path of the cooling liquid and the flow of the fluid flowing through the oil cooler 6 and the radiator 3, ensure that the temperature of the oil and the cooling liquid is in a suitable range, and the outlet ends of the oil cooler 6 and the radiator 3 are communicated with the inlet of the water return pump 5, so that the cooling liquid flowing through the two is combined after the main circulation and then flows into the water return pump 5, which is beneficial to provide sufficient power for the circulating system by the water return pump 5.

[0046] In some embodiments, the cooling system 100 further comprises a warm air water path 7, and the engine water jacket 1 is further provided with a cylinder head second water outlet 14, the inlet end of the warm air water path 7 is communicated with the cylinder head second water outlet 14, and the outlet end of the warm air water path 7 is communicated with the inlet end of the water return pump 5. That is, the cooling system 100 is provided with the warm air water path 7 connected in parallel with the thermostat 2 and the radiator 3, and part of the cooling liquid in the engine water jacket 1 flows into the thermostat 2 and the warm air water path 7 through the cylinder head first water outlet 12 and the cylinder head second water outlet 14 respectively, so that the cooling liquid flowing into the warm air water path 7 can dissipate heat to the space in the vehicle to heat the vehicle through the warm air.

[0047] And the outlet end of the heater water circuit 7 and the radiator 3 is communicated with the inlet of the return water pump 5, so that the cooling liquid flowing through the two is merged into the return water pump 5 after the main circulation, and the negative pressure formed in the return water pump 5 can increase the flow of the cooling liquid in the heater water circuit 7 and the radiator 3, so that the cooling liquid in the heater water circuit 7 and the radiator 3 has enough power to circulate, ensuring the performance of the heater heating and the radiator cooling.

[0048] In some embodiments, the cooling system 100 further comprises a supercharger 8, and the engine water jacket 1 is further provided with a third water outlet 15 of the cylinder head, the inlet end of the supercharger 8 is communicated with the third water outlet 15 of the cylinder head, and the outlet end of the supercharger 8 is communicated with the inlet end of the return water pump 5. That is, the cooling system 100 is provided with a supercharger 8 in parallel with the heater water circuit 7, so that the cooling liquid in the engine water jacket 1 can also enter the supercharger 8 to cool the supercharger 8, realizing the cooling effect of the supercharger 8, facilitating the control of the temperature of the supercharger 8, and ensuring that the supercharger 8 can continuously supercharge the engine.

[0049] Therefore, the cooling system 100 in the utility model can perform the functions of heating, engine cooling, supercharger 8 cooling and oil cooling, enriching the overall functionality of the cooling system 100 and enhancing the adaptability of the cooling system 100.

[0050] In some embodiments, the cooling system 100 further comprises a water storage tank 9, and the water storage tank 9 is provided with a water supplementing opening 91 for supplementing water to the return water pump 5. Therefore, the cooling liquid can be supplemented from the water supplementing opening 91 to the flow path of the cooling system 100 through the water storage tank 9, so that the cooling liquid can be supplemented in time when the amount of the cooling liquid in the flow path is small, avoiding the situation that the cooling liquid is insufficient to cause poor functional effect, and ensuring the cooling performance of the cooling system 100.

[0051] The water storage tank 9 is further provided with an exhaust opening 92, and the engine water jacket 1 and / or the radiator 3 are adapted to exhaust to the exhaust opening 92, that is, the engine water jacket 1 and the radiator 3 can exhaust to the exhaust opening 92 through an exhaust pipeline 93, so that the gas in the flow path of the cooling system 100 can be exhausted to the water storage tank 9, and then discharged to the atmosphere from the water storage tank 9. It should be noted that when the cooling system 100 is filled with cooling liquid, air bubbles will be mixed in, or the cooling liquid will locally boil to produce steam under high temperature. These gases flow with the cooling liquid in the circulating flow path, and the gas will form air resistance in the flow path, and cause pressure fluctuation in the flow path. By exhausting the gas to the water storage tank 9 through the exhaust opening 92, the air bubbles can be effectively prevented from forming air resistance, the flow pressure can be ensured to be stable, and the cooling liquid can flow smoothly.

[0052] In some embodiments, the component cooler 41 is configured as an EGR cooler. That is, the component cooler 41 connected in parallel with the engine water jacket 1 is configured as an EGR cooler, with its inlet end connected to the outlet end of the return water pump 5, and its outlet end connected between the cylinder head first water outlet 12 and the thermostat 2. That is, part of the coolant flowing out of the return water pump 5 can flow into the EGR cooler to cool the EGR.

[0053] like Figure 1 As shown, the EGR cooler is connected in parallel with the engine water jacket 1. The coolant flowing through the EGR cooler merges with the coolant flowing out of the first outlet 12 of the cylinder head and flows into the thermostat 2. This increases the fluid pressure in the flow path through the radiator 3 and the oil cooler 6, thereby reducing the pressure loss of the cooling system 100, increasing the flow rate of the radiator 3, and improving the heat dissipation efficiency.

[0054] It should be noted that the component cooler 41 of this utility model is not limited to the EGR cooler exemplified above, but can also be configured as an oil cooler 6 or other structures.

[0055] In some embodiments, the cooling system 100 further includes a water temperature sensor 10, which is used to detect the water temperature of the radiator 3. Figure 1 As shown, the cooling system 100 is also equipped with a water temperature sensor 10, which can monitor the temperature of the coolant in real time and transmit the temperature information to the control unit. The control unit can control the opening degree of the thermostat valve according to the temperature value detected by the water temperature sensor 10, so as to adjust the coolant flow of the radiator 3, thereby effectively adjusting the heat dissipation performance of the radiator 3. At the same time, the control unit adjusts the engine operating parameters according to the detected temperature value to ensure that the engine operates within a suitable temperature range and avoids the engine operating temperature from being too high.

[0056] This utility model also proposes a vehicle.

[0057] The vehicle according to the embodiments of this utility model includes the cooling system 100 of any of the above embodiments. The vehicle of this utility model, by setting up the cooling system 100, has the following advantages: The addition of a fluid booster flow path 4 connected in parallel with the engine water jacket 1 increases the system circulation pressure and reduces system pressure loss. Simultaneously, it increases the fluid velocity and flow rate through the radiator 3, improving the cooling effect of the radiator 3. Furthermore, the fluid booster flow path 4 can be configured as an EGR cooler or an oil cooler 6, or other structures, further improving the cooling efficiency of the cooling system 100. Therefore, the engine and other components in the vehicle can operate at suitable temperatures, which helps improve the vehicle's durability and enhances the overall competitiveness of the vehicle in the industry.
