[0024] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance or the number of specified technical features. Thus, a feature qualified by "first" or "second" may explicitly or implicitly include one or more of such features. Furthermore, in the description of this disclosure, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0025] A thermal management system 1 according to an embodiment of the present disclosure is described below with reference to the accompanying drawings.

[0026] As shown in FIGS. 1-4, a thermal management system 1 according to one embodiment of the present disclosure includes an engine cooler 100, an exhaust gas recirculation system cooler 200, and a thermal regulation and heat dissipation assembly 300.

[0027] The engine cooler 100 has a liquid inlet 110 and a liquid outlet 120. An outlet 201 of the exhaust gas recirculation system cooler 200 is in communication with the liquid inlet 110, and an inlet 202 of the exhaust gas recirculation system cooler 200 is in communication with the liquid outlet 120. That is, the exhaust gas recirculation system cooler 200 is connected in series to the engine cooler 100. An inlet 301 of a temperature regulation and heat dissipation assembly 300 is in communication with the inlet 202 of the exhaust gas recirculation system cooler 200, and an outlet 302 of the temperature regulation and heat dissipation assembly 300 is in communication with the outlet 201 of the exhaust gas recirculation system cooler 200. That is, the temperature regulation and heat dissipation assembly 300 is connected in parallel to the exhaust gas recirculation system cooler 200.

[0028] A part of the coolant flowing out of the liquid outlet 120 of the engine cooler 100 can flow to the temperature regulation and heat dissipation assembly 300 and then flow back to the engine cooler 100 through the liquid inlet 110. Another part of the coolant can flow to the exhaust gas recirculation system cooler 200 and then flow back to the engine cooler 100 after heat exchange. The engine cooler 100 can exchange heat with the engine to cool the engine quickly. In other words, when the temperature of the engine is too high, the engine can be cooled quickly so that the normal operation of the engine is guaranteed.

[0029] In the thermal management system 1 according to this embodiment of the present disclosure, the outlet 201 of the exhaust gas recirculation system cooler 200 is in communication with the liquid inlet 110, and the inlet of the exhaust gas recirculation system cooler 200 is in communication with the liquid outlet 120. The exhaust gas recirculation system cooler 200 is connected in series with the engine cooler 100. In this way, the engine cooler 100 and the exhaust gas recirculation system cooler 200 are connected in the same pipe, and the coolant in the engine cooler 100 can directly flow into the exhaust gas recirculation system cooler 200. In other words, there is no need to add an electronic water pump to provide the motive force of the coolant for the exhaust gas recirculation system cooler 200. Therefore, both the cooling demand of the engine cooler 100 and the cooling demand of the exhaust gas recirculation system cooler 200 can be satisfied, and the total flow rate of the coolant can be reduced, which reduces the flow rate of the electronic water pump, which further reduces the power consumption of the electronic water pump, and also reduces the engine oil consumption.

[0030] Furthermore, the temperature adjustment and heat dissipation assembly 300 is connected in series with the exhaust gas recirculation system cooler 200. Therefore, the coolant flowing out of the engine cooler 100 can flow through the exhaust gas recirculation system and through the temperature adjustment and heat dissipation assembly 300. In other words, there are two flow paths for the coolant flowing out of the engine cooler 100. In this way, during the warming process, the temperature adjustment and heat dissipation assembly 300 can be turned off. In this case, the coolant flowing out of the engine cooler 100 does not pass through the temperature adjustment and heat dissipation assembly 300. Furthermore, the rotation speed of the electronic water pump can be reduced so that less coolant enters the engine cooler 100, and the coolant flowing through the exhaust gas recirculation system cooler 200 can absorb the heat of the exhaust gas recirculation system for engine warming. In this way, the engine can be warmed up quickly, the engine warming efficiency can be greatly improved, the engine oil consumption can be further reduced, and the emission of harmful gases can be reduced.

[0031] Therefore, the thermal management system 1 according to this embodiment of the present disclosure has advantages such as low energy consumption, low engine oil consumption, and high heating speed.

[0032] In some embodiments of the present disclosure, as shown in Figures 1 to 4, a temperature regulation and heat dissipation assembly 300 includes a thermostat 320 and a radiator 310 connected in series. Specifically, the outlet 322 of the thermostat is in communication with the inlet 312 of the radiator 310, the inlet of the thermostat 320 is in communication with the inlet 202 of the exhaust gas recirculation system cooler 200, and the outlet of the radiator 310 is in communication with the outlet 210 of the exhaust gas recirculation system cooler 200. That is, the thermostat 320 and the radiator 310 are in the same line, and the exhaust gas recirculation system cooler 200 is in another line. A portion of the refrigerant flowing out of the liquid outlet 120 of the engine cooler 100 can flow to the thermostat 320 and the radiator 310, and then flow back to the engine cooler 100 through the liquid inlet 110. The other part of the refrigerant can flow to the exhaust gas recirculation system cooler 200 and then back to the engine cooler 100 after heat exchange. In other words, there are two flow paths for the refrigerant flowing out of the engine cooler 100. In this way, during the warming process, the thermostat 300 can be turned off. In this case, the refrigerant flowing out of the engine cooler 100 does not pass through the radiator 310. In addition, the rotation speed of the electronic water pump may be reduced so that less refrigerant enters the engine cooler 100, and the refrigerant flowing through the exhaust gas recirculation system cooler 200 can absorb the heat of the exhaust gas recirculation system for warming up the engine. In this way, the engine is warmed up quickly.

[0033] In some embodiments of the present disclosure, as shown in Figures 1 to 4, the thermal management system 1 further includes a warm air module 400. An outlet 401 of the warm air module 400 is in communication with the liquid inlet 110, and an inlet 402 of the warm air module 400 is in communication with the liquid outlet 120. That is, the warm air module 400 is connected in series with the engine cooler 100. Thus, the warm air module 400 and the engine cooler 100 can form a circuit. The refrigerant in the engine cooler 100 flowing through the warm air module 400 can heat the passenger compartment so that the engine heat can be used to heat the passenger compartment, thereby improving the utilization of the engine heat and reducing energy consumption.

[0034] In some embodiments of the present disclosure, as shown in FIG. 1 to FIG. 4, the warm air module 400 is connected in parallel to the exhaust gas recirculation system cooler 200, or the warm air module 400 is connected in series to the exhaust gas recirculation system cooler 200. In this way, the connection between the warm air module 400 and the exhaust gas recirculation system cooler 200 is simpler. In other words, a portion of the coolant flowing out of the engine cooler 100 can flow to the exhaust gas recirculation system cooler 200, and another portion of the coolant can flow to the warm air module 400. In this way, the coolant and heat dissipation device are shared by the warm air module 400, the exhaust gas recirculation system cooler 200, and the engine cooler 100, and no additional electronic water pump is required to provide the coolant thrust for the exhaust gas recirculation system cooler 200. The flow rate and number of components of the electronic water pump are reduced, but the cooling requirements of the exhaust gas recirculation system cooler 200 are guaranteed. In this way, the power consumption of the electronic water pump is also reduced to a certain extent, which results in a reduction in engine oil consumption, and also simplifies the vehicle structure, thereby reducing costs.

[0035] In some embodiments of the present disclosure, as shown in FIGS. 1 to 4 , the temperature management system 1 further includes a battery cooling system 500, a first heat exchange plate 600, and a three-way valve 700.

[0036] The first heat exchange plate 600 has a first heat exchange channel 610 and a second heat exchange channel 620. The first heat exchange channel 610 is connected to the battery cooling system 500, and a first end 621 of the second heat exchange channel 620 is in communication with the liquid inlet 110. The three-way valve 700 includes a first opening 710, a second opening 720, and a third opening 730. The first opening 710 is in communication with the liquid inlet 110, the second opening 720 is in communication with the second end 622 of the second heat exchange channel 620, and the third opening 730 is in communication with the warm air module 400. The third opening 730 can be selectively in communication with one of the first opening 710 and the second opening 720.

[0037] In other words, the refrigerant in the engine cooler 100 can flow through the second heat exchange channel 620, and the refrigerant in the battery cooling system 500 can flow through the first heat exchange channel 610. In this way, the refrigerant in the engine cooler 100 and the refrigerant in the battery cooling system 500 can exchange heat at the first heat exchange plate 600, so that the battery cooling system 500 is heated by using the engine cooler 100, thereby further improving the temperature rise rate of the battery cooling system 500 and ensuring the battery efficiency. In this way, no additional energy is needed when the battery pack 510 is heated, so that the efficiency of the battery pack 510 is improved, and no additional power consumption is needed, so that the energy utilization is improved.

[0038] When the second opening 720 is in communication with the first opening 710, the engine cooler 100 is not in communication with the first heat exchange plate 600. In other words, the first heat exchange plate 600 is not involved in the refrigerant loop in the engine cooler 100, the engine cooler 100 and the battery cooling system 500 do not exchange heat, and the first heat exchange plate 600 is equivalent to a pipe. When the second opening 720 is in communication with the third opening 730, the engine cooler 100 and the battery cooling system 500 exchange heat through the first heat exchange plate 600, and the engine cooler 100 can heat the battery cooling system 500.

[0039] In some embodiments of the present disclosure, as shown in Figures 1-4, the third opening 730 communicates with the warm air module 400 through the exhaust gas recirculation system cooler 200.

[0040] In this way, when the battery pack 510 needs to be heated, the coolant exchanges heat with the exhaust gas recirculation system cooler 200 before flowing through the second heat exchange channel 620 to absorb the heat of the exhaust gas recirculation system. Therefore, the temperature of the coolant flowing through the second heat exchange channel 620 is higher, and the temperature of the coolant entering the second heat exchange channel 620 of the first heat exchange plate 600 is rapidly increased. Specifically, when the engine starts in a low temperature environment, heat can be rapidly provided to the battery cooling system 500, so that the battery pack 510 quickly reaches an appropriate temperature, thereby ensuring the battery efficiency. Furthermore, after the exhaust gas recirculation system cooler 200 is connected in series with the warm air module 400, an electronic water pump does not need to be added to the exhaust gas recirculation system cooler 200, and the electronic water pump does not need to further increase the flow rate. In other words, the same water pump can be shared by the exhaust gas recirculation system cooler 200 and the engine cooler 100. The power consumption of the electronic water pump can be reduced to a certain extent, thereby reducing the engine oil consumption.

[0041] In some embodiments of the present disclosure, as shown in FIGS. 1 to 4, the temperature management system 1 further includes an air conditioning system 800 and a second heat exchange plate 900.

[0042] The second heat exchange plate 900 has a third heat exchange channel 910 and a fourth heat exchange channel 920. The third heat exchange channel 910 is connected to the battery cooling system 500, and the fourth heat exchange channel 920 is connected to the air conditioning system 800.

[0043] In other words, the refrigerant in the battery cooling system 500 can flow through the third heat exchange channel 910, and the cooling medium in the air conditioning system 800 can flow through the fourth heat exchange channel 920, and the refrigerant in the third heat exchange channel 910 can exchange heat with the cooling medium in the fourth heat exchange channel 920. In this way, when the environmental temperature is relatively low, the cooling medium in the air conditioning system 800 can be used to heat the refrigerant in the battery cooling system 500 to increase the temperature of the refrigerant in the battery cooling system 500, and the battery pack 510 is heated by using the refrigerant in the battery cooling system 500, ensuring that the battery pack 510 is within a suitable operating temperature range. When the environmental temperature is relatively high, the cooling medium in the air conditioning system 800 can be used to cool the refrigerant in the battery cooling system 500 to decrease the temperature of the refrigerant in the battery cooling system 500, and the battery pack 510 is cooled by using the refrigerant in the battery cooling system 500, and the battery pack 510 is kept in a normal operating state.

[0044] Furthermore, through the arrangement of the first heat exchange plate 600 and the second heat exchange plate 900, the engine cooler 100 and the air conditioning system 800 can exchange heat with the battery cooling system 500 at the same time, which further enhances the temperature rise rate of the battery cooling system 500 and also rapidly increases the temperature of the battery pack 510. Therefore, when the battery pack 510 is heated, no additional energy is required, so that the efficiency of the battery pack 510 is improved and no additional power consumption is required. It can be understood that when the battery pack 510 needs to be heated, only the engine cooler 100 may be used to exchange heat with the battery cooling system 500, and the air conditioning system 800 may not exchange heat with the battery cooling system 500, or only the air conditioning system 800 may be used to exchange heat with the battery cooling system 500, and the engine cooler 100 may not exchange heat with the battery cooling system 500.

[0045] In some embodiments of the present disclosure, as shown in FIGS. 1-4, an air conditioning system 800 includes a compressor 810, a first heat exchanger 820, and a second heat exchanger 830.

[0046] A first end 821 of the first heat exchanger 820 is connected to the compressor 810, a first end 831 of the second heat exchanger 830 is connected to a second end 822 of the first heat exchanger 820 through a switching valve 840, and a second end 832 of the second heat exchanger 830 is connected to the compressor 810. The two ends of the fourth heat exchange channel 920 are connected to the compressor 810 and the second end 822 of the first heat exchanger 820, respectively. An expansion valve is disposed between the first heat exchanger 820 and the second heat exchanger 830. The expansion valve may be a thermal expansion valve. The expansion valve may be disposed between the switching valve 840 and the second heat exchanger 830.

[0047] For example, the first heat exchanger 820 may function as a condenser for the air conditioning system 800 to heat, and the second heat exchanger 830 may function as an evaporator for the air conditioning system 800 to cool. Additionally, a battery management system (BMS) sends a request signal for cooling, heating, or equalization to a microcontroller unit (MCU) based on the signal of a temperature sensor in the battery pack 510. The MCU sets temperature targets and limits for all components based on the BMS request signal and the temperature and pressure sensors of the air conditioning system 800, and based on experimental and simulation parameters, to control the compressor 810, the electronic expansion valve 850 described below, and the electronic water pump to achieve optimal temperature and energy consumption targets under various operating conditions.

[0048] During refrigeration of the air conditioning system 800, a portion of the refrigerant exiting the first heat exchanger 820 flows through the fourth heat exchange channel 920 and exchanges heat with the refrigerant in the third heat exchange channel 910, thereby cooling the battery cooling system 500. Another portion of the refrigerant flows through the switching valve 840 and the second heat exchanger 830. Thus, the compressor 810, the first heat exchanger 820, the switching valve 840, and the second heat exchanger 830 form a cooling medium loop. The first heat exchanger 820 is a condenser, and the second heat exchanger 830 is an evaporator configured to cool the vehicle cabin.

[0049] In some embodiments of the present disclosure, as shown in Figures 1 to 4, an electronic expansion valve 850 is disposed between the fourth heat exchange channel 920 and the first heat exchanger 820. In this manner, the electronic expansion valve 850 can control the connection and disconnection between the fourth heat exchange channel 920 and the air conditioning system 800, so that the refrigerant in the air conditioning system 800 does not exchange heat with the battery cooling system 500 when the temperature of the battery pack 510 is normal and the battery pack 510 does not need to be heated or cooled.

[0050] When the air conditioning system 800 performs supplemental cooling on the battery cooling system 500, the electronic expansion valve 850 is switched on, and the low-temperature, low-pressure gas passes through the compressor 810 to become a high-temperature, high-pressure gas. The high-temperature, high-pressure gas passes through the first heat exchanger 820 to become a low-pressure, low-temperature liquid. A part of the high-pressure, low-temperature liquid enters the second heat exchanger 830, so that the compressor 810, the first heat exchanger 820, and the second heat exchanger 830 form a cooling medium loop to cool the vehicle cabin. The other part of the high-pressure, low-temperature liquid enters the fourth heat exchange channel 920 through the electronic expansion valve 850 to exchange heat with the battery cooling system 500, and then becomes a low-pressure, low-temperature gas into the compressor 810 to complete the cycle. In this case, the first heat exchanger 820 is a condenser, and the second heat exchanger 830 is an evaporator.

[0051] In some embodiments of the present disclosure, as shown in FIGS. 1-6 , the engine cooler 100 includes a cylinder head water jacket 140, a cylinder block water jacket 130, and a connection water jacket 150.

[0052] The cylinder head water jacket 140 is configured to cool the cylinder head of the engine, and the liquid outlet 120 is disposed on the cylinder head water jacket 140. The cylinder block water jacket 130 is configured to cool the cylinder block of the engine. The outlet 133 of the cylinder block water jacket 13 communicates with the liquid outlet 120. The inlet 134 of the cylinder block water jacket 130 communicates with the inlet 141 of the cylinder head water jacket 140. All the parts of the engine have a good cooling effect and are cooled more sufficiently. The liquid inlet 110 is disposed on the connection water jacket 150. The liquid inlet 110 communicates with the inlet 141 of the cylinder head water jacket 140 and the inlet 134 of the cylinder block water jacket 130 respectively. In other words, the cylinder head water jacket 140 and the cylinder block water jacket 130 are connected in parallel and connected in series to the junction water jacket 150 .

[0053] It should be noted that the cylinder block water jacket 130 and the cylinder head water jacket 140 are connected in parallel, and the cylinder block water jacket 130 and the cylinder head water jacket 140 are connected in series to the connecting water jacket 150. This means that after the cylinder block water jacket 130 is connected in parallel to the cylinder head water jacket 140, the two of them as a whole communicate with the connecting water jacket 150. The refrigerant flowing out through the connecting water jacket 150 can flow to the cylinder block water jacket 130 and the cylinder head water jacket 140 respectively. The refrigerant flowing out from the cylinder block water jacket 130 and the cylinder head water jacket 140 can be collected and then divided into three parts. One part flows to the expansion kettle to remove gas generated in the engine cooler 100 system, and refills the motor pump in the engine cooler 100 through the expansion kettle to maintain the flow pressure of the refrigerant in the engine cooler 100 and prevent boiling or cavitation of the electronic water pump. One part passes through the warm air module 400 and enters the exhaust gas recirculation system cooler 200. When the battery cooling system 500 has a heating demand, the third opening 730 of the three-way valve 700 communicates with the second opening 720, and the refrigerant in the warm air module 400 flows into the first heat exchange plate 600 to exchange heat with the battery cooling system 500, and then flows back to the engine cooler 100. When the battery cooling system 500 has no heating demand, the third opening 730 of the three-way valve 700 communicates with the first opening 710, and the refrigerant in the warm air module 400 flows directly to the original engine cooler 100. One part enters the thermostat 300. When the thermostat 300 is turned on, the refrigerant enters the radiator 310 for heat dissipation and flows to the original engine cooler 100 to complete the cycle. When the thermostat 300 is not turned on, the radiator 310 does not participate in the cycle.

[0054] Furthermore, the flow rate from the connection water jacket 150 to the cylinder block water jacket 130 and the flow rate in the cylinder head water jacket 140 can be properly allocated through adjusting the size of the communication port between the connection water jacket 150 and the cylinder block water jacket 130 and adjusting the size of the communication port between the connection water jacket 150 and the cylinder head water jacket 140, so that the warm-up time of the engine can be shortened during starting in a low temperature environment, thereby reducing the oil consumption and the emission of harmful gases. For example, when the communication port between the connection water jacket 150 and the cylinder block water jacket 130 is enlarged, the flow rate of the coolant entering the cylinder block water jacket 130 is increased and the flow rate of the coolant entering the cylinder head water jacket 140 is decreased. In this way, the cooling speed of the engine cooler 100 to the cylinder block and cylinder head of the engine can be adjusted.

[0055] In some embodiments of the present disclosure, as shown in FIGS. 1-6 , the thermal management system 1 further includes a supercharger cooler 160 .

[0056] The cylinder block water jacket 130 has a gas inlet side water jacket 131 and a gas outlet side water jacket 132 facing each other. The gas inlet side water jacket 131 is connected to the connection water jacket 150. The gas outlet side water jacket 132 communicates with the turbocharger cooler 160. The gas inlet side water jacket 131 and the gas outlet side water jacket 132 communicate with the liquid outlet 120 separately. In this way, the coolant flowing out from the gas outlet side water jacket 132 can flow into the turbocharger cooler 160. The turbocharger cooler 160 can cool the turbocharger to avoid excessive high temperature of the turbocharger, so that the turbocharger can operate normally.

[0057] As shown in FIG. 7, according to a vehicle 2 in an embodiment of the second aspect of the present disclosure, the vehicle 2 includes a thermal management system 1 according to an embodiment of the first aspect of the present disclosure.

[0058] According to this embodiment of the present disclosure, the vehicle 2 has advantages such as low energy consumption, low oil consumption, and high heating rate through the thermal management system 1.
