Description

Technical Field

[0001] This invention relates to the field of thermal management technology, and more particularly to a thermal management system, control method, device, electronic equipment, computer-readable storage medium, and vehicle. Background Technology

[0002] Thermal management systems include direct heat pump systems and indirect heat pump systems. Direct heat pump systems exchange heat directly with the high-temperature refrigerant gas through an in-vehicle condenser, while indirect heat pump systems require the high-temperature refrigerant gas to first heat the coolant before the coolant transfers heat to the heater core to heat the air. Direct heat pumps are favored in specific applications due to their ability to quickly heat air and their lower cost, while indirect heat pumps offer advantages in safety, system stability, and uniform airflow.

[0003] For hybrid vehicles, if a direct heat pump system is used, it is difficult to use the engine's waste heat to heat the passenger compartment, while if an indirect heat pump system is used, it will lead to increased energy consumption of the compressor.

[0004] Therefore, a thermal management system is proposed in the related technology, including a compressor, an indoor condenser, a heater core, an engine, and a battery. The indoor condenser is connected to the compressor, and the refrigerant can generate a large amount of heat in the indoor condenser and the battery respectively to meet the heating needs of the passenger compartment and the battery. At the same time, the heater core can also form a heating circuit with the engine. The engine transfers heat to the heater core through the coolant flowing in the circuit to heat the passenger compartment and realize the utilization of the engine's waste heat. Therefore, the above-mentioned related technology not only utilizes the engine's waste heat but also avoids the increase in compressor energy consumption.

[0005] However, in the aforementioned technologies, the battery uses a refrigerant cooling method (the battery is connected to the compressor), which makes it difficult to use the engine's waste heat to heat the battery, resulting in low thermal utilization of the entire thermal management system.

[0094] Example 1

[0095] like Figures 1-12As shown, this embodiment proposes a thermal management system for use in a vehicle to control the temperature of the electric drive assembly, passenger compartment, battery, and engine, thereby ensuring the stable operation of the entire vehicle. The thermal management system includes a heating circuit, a battery circuit, and a refrigerant circuit. The heating circuit includes an engine 1, a heater core 2, and a first heat exchanger 3. The coolant in the heating circuit can transfer the waste heat generated by the engine 1 to the heater core 2, thereby heating the passenger compartment. The battery circuit includes a battery 10, a first heat exchanger 3, and a second heat exchanger 9. The first heat exchanger 3 includes two coolant pipes. One coolant pipe is connected to the engine 1 and the heater core 2 to form the heating circuit, and the other coolant pipe is connected to the battery 10 to form the battery circuit, i.e., the battery return circuit. The circuit is coupled to the heating circuit through the first heat exchanger 3. The refrigerant circuit is equipped with a compressor 4, an internal condenser 5, a first throttle valve 6, a second throttle valve 8, an evaporator 7, and a second heat exchanger 9. The internal condenser 5, the evaporator 7, and the heater core 2 are all located inside the air conditioning unit. The second heat exchanger 9 includes a coolant pipe and a refrigerant pipe. The refrigerant pipe is connected to the compressor 4, the internal condenser 5, the first throttle valve 6, the second throttle valve 8, and the evaporator 7 to form a refrigerant circuit, while the coolant pipe is connected to the battery 10 and the second heat exchanger 9 to form a battery circuit.

[0096] The heating circuit in the aforementioned thermal management system can achieve heat exchange with the battery circuit using the first heat exchanger 3. When the battery 10 requires heating and the engine 1 has residual heat, the coolant in the heating circuit exchanges heat with the coolant in the battery circuit, thereby transferring the residual heat generated by the engine 1 to the battery 10 through heat exchange, thus utilizing the residual heat of the engine 1 to heat the battery 10. Of course, when the passenger compartment requires heating, the residual heat generated by the engine 1 can be used to heat the passenger compartment through the heater core 2 installed in the air conditioning unit of the passenger compartment.

[0097] It is important to emphasize that, since the heater core 2 is connected to the engine 1, when using the waste heat of the engine 1 to heat the passenger compartment, the engine 1's own water pump can provide the power for the coolant to flow in the heating circuit, eliminating the need for an additional water pump and reducing the manufacturing cost of the thermal management system. Furthermore, the refrigerant absorbs heat from the battery 10 at the second heat exchanger 9 and releases heat at the internal condenser 5, meaning the internal condenser 5 can also be used to heat the passenger compartment. Because the internal condenser 5 does not need to exchange heat with the heater core 2 to heat the passenger compartment, the compressor 4 has low energy consumption.

[0098] The heating circuit includes a first heating sub-circuit and a second heating sub-circuit. The engine 1 and the heater core 2 are connected in series to form the first heating sub-circuit, and the engine 1 and the first heat exchanger 3 are connected in series to form the second heating sub-circuit. That is, the heater core 2 and the first heat exchanger 3 are connected in parallel to the engine 1. By controlling the on / off state of the first and second heating sub-circuit, different thermal management needs can be met. For example, when only the waste heat from the engine 1 is needed to heat the passenger compartment without heating the battery 10, the first heating sub-circuit is circulated, and the second heating sub-circuit is disconnected (because the first heat exchanger 3...). In the second heating sub-circuit (where the heating circuit is disconnected from the battery circuit), when only the waste heat of engine 1 is needed to heat battery 10 without heating the passenger compartment, the second heating sub-circuit is activated and the first heating sub-circuit is disconnected, and the coolant does not flow through the heater core 2. When the waste heat of engine 1 is needed to heat both the passenger compartment and battery 10 simultaneously, both the first and second heating sub-circuit are activated and circulated. The coolant flowing through engine 1 can flow through heater core 2 to heat the passenger compartment, and at the same time, it can flow through first heat exchanger 3 to exchange heat with the battery circuit to heat battery 10.

[0099] Specifically, the on / off state of the first heating sub-circuit and the second heating sub-circuit is controlled by the first three-way valve 19. The first three-way valve 19 includes a first port 19a, a second port 19b, and a third port 19c. The first port 19a is connected to the outlet of the engine 1, the second port 19b is connected to the inlet of the heater core 2, and the third port 19c is connected to the inlet of one of the coolant channels of the first heat exchanger 3. The outlet of the coolant channel connected to the first heat exchanger 3 and the third port 19c is connected to the inlet of the engine 1 and the outlet of the heater core 2. When the first port 19a and the second port 19b are open, and the third port 19c is closed, the first heating circuit is connected, and the second heating sub-circuit is disconnected; when the first port 19a and the third port 19c are open, and the second port 19b is closed, the second heating sub-circuit is connected, and the first heating sub-circuit is disconnected; when the first port 19a, the second port 19b, and the third port 19c are all open, both the first and second heating sub-circuit are connected. It can be understood that when the first port 19a, the second port 19b, and the third port 19c are all open, the flow rate ratio of the coolant flowing to the warm air core 2 and the first heat exchanger 3 can be adjusted by controlling the opening degree of the first three-way valve 19.

[0100] In order to dissipate the heat generated by engine 1 in a timely manner, the heating circuit also includes a high-temperature radiator 15. The high-temperature radiator 15 is connected in series with engine 1 to form a third heating sub-circuit. When engine 1 has residual heat and neither the crew compartment nor the battery 10 has a heating requirement, the third heating sub-circuit is used to dissipate heat from engine 1. At this time, the first port 19a of the first three-way valve 19 is closed.

[0101] Specifically, in the refrigerant circuit, the compressor 4, the internal condenser 5, the first throttle valve 6, and the second heat exchanger 9 are connected in series to form a first refrigerant sub-circuit. The second heat exchanger 9 is provided with a refrigerant flow channel and a coolant flow channel. The refrigerant flow channel is connected to the compressor 4, the internal condenser 5, and the first throttle valve 6 to form the first refrigerant sub-circuit, while the coolant flow channel in the second heat exchanger 9 is connected to the battery 10. That is, the second heat exchanger 9 belongs to both the battery circuit and the first refrigerant sub-circuit. The second heat exchanger 9 can transfer the heat generated by the battery 10 to the first refrigerant sub-circuit to heat the passenger compartment. The compressor 4, the internal condenser 5, the second throttle valve 8, and the evaporator 7 are connected in series to form a second refrigerant sub-circuit. The evaporator 7 is located in the air conditioning unit and is used to cool the passenger compartment.

[0102] Specifically, the evaporator 7, the internal condenser 5, and the heater core 2 are arranged sequentially in the air conditioning unit according to the airflow direction. In range-extended mode, since the heater core 2 is located downstream of the internal condenser 5 along the airflow direction, the compressor 4 can be turned off and only the heater core 2 can be used to heat the passenger compartment. Moreover, when the passenger compartment needs to be cooled, the heater core 2, which is located downstream of the internal condenser 5, can reduce the heat leakage of the internal condenser 5.

[0103] In this embodiment, the thermal management system also includes an electric drive circuit, which can be coupled to the battery circuit through the second heat exchanger 9 and provide heat to the first refrigerant circuit through the second heat exchanger 9, thereby making full use of the waste heat of the electric drive assembly 14.

[0104] The electric drive circuit is equipped with an electric drive assembly 14, the aforementioned second heat exchanger 9, and a first water pump 12. The electric drive assembly 14, the aforementioned second heat exchanger 9, and the aforementioned first water pump 12 are connected in series to form a first electric drive sub-circuit. The electric drive assembly 14 and the aforementioned first water pump 12 are connected in series to form a second electric drive sub-circuit. The second electric drive sub-circuit is used to meet the natural heat dissipation requirements of the electric drive assembly 14.

[0105] The electric drive circuit also includes a low-temperature radiator. The low-temperature radiator 16 is connected in series with the first water pump 12 and the electric drive assembly 14 to form a third electric drive sub-circuit, which is used to improve the heat dissipation efficiency of the electric drive assembly 14.

[0106] In order to meet the heating requirements of battery 10 and / or crew compartment when there is no residual heat in engine 1 and electric drive assembly 14, refer to Figure 1 As shown, a heater 11 is also provided in the battery circuit. The heater 11 can heat the coolant in the battery circuit to meet the heating requirements of the battery 10. At the same time, the refrigerant circuit can exchange heat with the battery circuit through the second heat exchanger 9 to meet the heating requirements of the crew compartment.

[0107] To prevent the heater 11 from affecting the battery 10 when heating the crew compartment, the battery circuit includes a first battery sub-circuit, a second battery sub-circuit, a third battery sub-circuit, and a fourth battery sub-circuit. The second water pump 13, the heater 11, and the battery 10 are connected in series to form the first battery sub-circuit. The first heat exchanger 3, the second water pump 13, and the heater 11 are connected in series to form the second battery sub-circuit. The heater 11, the first heat exchanger 3, the second heat exchanger 9, and the second water pump 13 are connected in series to form the third battery sub-circuit. The battery 10, the second heat exchanger 9, the second water pump 13, and the heater 11 are connected in series to form the fourth battery sub-circuit.

[0108] When the crew compartment needs to be heated by heater 11 but the battery 10 does not require heating, the third battery sub-circuit is activated, while the first, second, and fourth battery sub-circuits are deactivated.

[0109] In this embodiment, the first heat exchanger 3 and the battery 10 are connected in parallel and then connected to the heater 11. When the heater 11 heats the battery 10, it does not need to pass through the first heat exchanger 3, thus reducing the power required by the heater 11. In other embodiments, the first heat exchanger 3 and the battery 10 can also be connected in series.

[0110] The on / off state of each sub-circuit in the battery circuit is controlled by the first four-way valve 21. The first four-way valve 21 includes a first port 21a, a second port 21b, a third port 21c, and a fourth port 21d. The first port 21a is connected to the outlet of the battery 10, the second port 21b is connected to the outlet of the first heat exchanger 3, the third port 21c is connected to the inlet of the second heat exchanger 9, and the fourth port 21d is connected to the inlet of the heater 11 and the inlet of the battery 10. When the first interface 21a and the fourth interface 21d are open, and the second interface 21b and the third interface 21c are closed, the first battery sub-circuit is cyclically connected, while the second, third, and fourth battery sub-circuit are disconnected. When the first interface 21a, the second interface 21b, and the fourth interface 21d are open, and the third interface 21c is closed, the first and second battery sub-circuit are open, while the third and fourth battery sub-circuit are disconnected. When the second interface 21b and the third interface 21c are open, and the first interface 21a and the fourth interface 21d are closed, the third battery sub-circuit is cyclically connected, while the first, second, and fourth battery sub-circuit are disconnected. When the first interface 21a and the third interface 21c are open, and the second interface 21b and the fourth interface 21d are closed, the fourth battery sub-circuit is cyclically connected, while the first, second, and third battery sub-circuit are disconnected.

[0111] The on / off state of each sub-circuit in the electric drive circuit is controlled by the second four-way valve 22. The second four-way valve 22 includes a first connecting port 22a, a second connecting port 22b, a third connecting port 22c, and a fourth connecting port 22d. The first connecting port 22a is connected to the inlet of the electric drive assembly 14, the second connecting port 22b is connected to the inlet of the second heat exchanger 9, the third connecting port 22c is connected to the outlet of the second heat exchanger 9 and the outlet of the low-temperature radiator 16, and the fourth connecting port 22d is connected to the outlet of the electric drive assembly 14. When the first connection port 22a and the fourth connection port 22d are open, and the second connection port 22b and the third connection port 22c are closed, the second electric drive sub-circuit is cyclically connected, and the first and third electric drive sub-circuit are disconnected; when the first connection port 22a and the second connection port 22b are open, and the third connection port 22c and the fourth connection port 22d are closed, the first electric drive sub-circuit is cyclically connected, and the second and third electric drive sub-circuit are disconnected; when the first connection port 22a and the third connection port 22c are open, the second connection port 22b and the fourth connection port 22d are closed, the third electric drive sub-circuit is cyclically connected, and the first and second electric drive sub-circuit are disconnected.

[0112] Example 2

[0113] refer to Figure 13 As shown, unlike Embodiment 1, the heater 11 belongs to the heating circuit to realize the on-demand water priming function of the engine 1. In order to reduce the manufacturing cost of the thermal management system, the first three-way valve 19 between the heater core 2 and the first heat exchanger 3 is eliminated, and the heater core 2 and the first heat exchanger 3 are connected in series.

[0114] To prevent the heater 11 from affecting the engine 1 when it is working, the engine 1 is connected in parallel with the heater 11. At this time, in order to provide power to the coolant flowing through the heater 11, a third water pump 24 connected in series with the heater 11 is also provided in the heating circuit.

[0115] Specifically, the heating circuit includes a first heating sub-circuit, a second heating sub-circuit, and a third heating sub-circuit. The engine 1, the third water pump 24, the heater 11, and the first heat exchanger 3 are connected in series to form the first heating sub-circuit. The third water pump 24, the heater 11, and the first heat exchanger 3 are connected in series to form the second heating sub-circuit. The engine 1 and the high-temperature radiator 15 are connected in series to form the third heating sub-circuit.

[0116] Specifically, a second three-way valve 20 is installed on the heating circuit. The second three-way valve 20 includes a first connection port 20a, a second connection port 20b, and a third connection port 20c. The first connection port is connected to the outlet of the first heat exchanger 3, the second connection port 20b is connected to the inlet of the engine 1, and the third connection port 20c is connected to the outlet of the engine 1 and the inlet of the heater 11. When the first connection port 20a and the second connection port 20b are open, and the third connection port 20c is closed, the first heating sub-circuit is circulated, and the second heating sub-circuit is disconnected. When the first connection port 20a and the third connection port 20c are open, and the second connection port 20b is closed, the second heating sub-circuit is circulated, and the first heating sub-circuit is disconnected.

[0117] The vehicle's air conditioning unit is equipped with a cold air duct, a hot air duct, a mixing chamber, and a temperature damper. The heater core 2 is located in the hot air duct, and the evaporator 7 is located in the cold air duct. The cold air flowing out of the cold air duct and the hot air flowing out of the hot air duct are mixed in the mixing chamber. The mixed gas is discharged from the air outlet of the unit. The temperature damper can control the airflow passing through the heater core 2 to adjust the mixing ratio of cold and hot air in the mixing chamber, thereby controlling the air conditioning outlet temperature. In other words, even if the heater core 2 is connected in series with the first heat exchanger 3, the heater core 2 located in the hot air duct can be isolated from the mixing chamber by adjusting the temperature damper, so as to prevent the heating of the heater 11 from affecting the passenger compartment temperature when only the battery 10 has a heating requirement.

[0118] Of course, in other embodiments, a heater 11 can be added to the warm air circuit based on the parallel connection of the warm air core 2 and the first heat exchanger 3, which will not be elaborated here.

[0119] Example 3

[0120] refer to Figure 14 As shown, unlike Embodiment 1 or Embodiment 2, in this embodiment, the thermal management system further includes a third heat exchanger 23. The third heat exchanger 23 has a coolant flow channel and a refrigerant flow channel. The third heat exchanger 23 is located on the first refrigerant sub-circuit, and its refrigerant flow channel is connected to the outlet of the internal condenser 5. The coolant flow channel of the third heat exchanger 23 is connected to the electric drive assembly 14 to form a fourth electric drive sub-circuit. The refrigerant circuit achieves heat exchange with the electric drive circuit through the third heat exchanger 23, thereby enabling the electric drive circuit to dissipate heat from the refrigerant, meeting the increased cooling requirements of super-fast charging such as 6C, while also improving heating capacity.

[0121] The electric drive circuit also includes an intercooler 17, which is connected in series with the electric drive assembly 14 to form a fifth electric drive sub-circuit. In addition, the thermal management system also includes a third four-way valve 26 to regulate the flow rate of coolant through the electric drive assembly 14, the intercooler 17, and the third heat exchanger 23. The third four-way valve 26 includes a first valve port 26a, a second valve port 26b, a third valve port 26c, and a fourth valve port 26d. The first valve port 26a is connected to the inlet of the low-temperature radiator 16, the inlet of the first heat exchanger 3, and the inlet of the second heat exchanger 9; the second valve port 26b is connected to the inlet of the third heat exchanger 23; the third valve port 26c is connected to the outlet of the electric drive assembly 14, the outlet of the third heat exchanger 23, and the outlet of the intercooler 17; and the fourth valve port 26d is connected to the inlet of the intercooler 17.

[0122] Example 4

[0123] refer to Figure 15 As shown, unlike Embodiment 1 or Embodiment 2, in this embodiment, the thermal management system includes a third heat exchanger 23. The third heat exchanger 23 is different from the third heat exchanger 23 in Embodiment 3. The refrigerant flow channel of the third heat exchanger 23 is connected to the inlet of the internal condenser 5, and the coolant flow channel of the third heat exchanger 23 is connected in series with the outlet of the first heat exchanger 3. That is, the heating circuit achieves heat exchange with the refrigerant circuit through the third heat exchanger 23, so as to fully utilize the heating capacity of the refrigerant circuit.

[0124] Example 5

[0125] refer to Figure 16 As shown, based on Embodiment 4, the thermal management system in this embodiment further includes a third three-way valve 25. The third three-way valve 25 is located between the internal condenser 5 and the third heat exchanger 23. While connecting the inlet of the internal condenser 5 and the outlet of the third heat exchanger 23, the third three-way valve 25 also bypasses the outlet of the internal condenser 5. The third three-way valve 25 is a proportional three-way valve, allowing for flexible adjustment of the refrigerant flow rate into the internal condenser 5. To prevent refrigerant flowing out of the bypass port of the third three-way valve 25 from entering the internal condenser 5, a one-way valve is connected to the outlet of the internal condenser 5.

[0126] Example 6

[0127] refer to Figure 17As shown, based on Embodiment 4, the thermal management system in this embodiment includes a third three-way valve 25. Unlike the third three-way valve 25 in Embodiment 4, the third three-way valve 25 in this embodiment enables the internal condenser 5 and the third heat exchanger 23 to be connected in parallel, thereby reducing the resistance of the refrigerant circuit and thus reducing the losses of the compressor 4. Specifically, the third three-way valve 25 connects the outlet of the compressor 4, the inlet of the internal condenser 5, and the inlet of the third heat exchanger 23, while the outlet of the third heat exchanger 23 is connected to the outlet of the internal condenser 5. To prevent refrigerant from entering the internal condenser 5 from the outlet of the third heat exchanger 23, a one-way valve is connected to the outlet of the internal condenser 5.

[0128] Example 7

[0129] Based on Embodiment 6, the thermal management system in this embodiment includes an electronic thermostat (not shown in the figure). The electronic thermostat is connected to the engine 1 to automatically adjust the flow rate into the high-temperature radiator 15 according to the temperature of the coolant flowing out of the engine 1, thereby realizing the function of using the high-temperature radiator 15 to dissipate heat from the refrigerant circuit.

[0130] Example 8

[0131] refer to Figure 18 Unlike Embodiment 1 or Embodiment 2, the thermal management system also includes an outdoor heat exchanger 18, which is installed in the refrigerant circuit to dissipate heat from the refrigerant. The outdoor heat exchanger 18, the compressor 4, and the internal condenser 5 are connected in series to form a third refrigerant sub-circuit.

[0145] The target working modes also include the fifth, sixth, seventh, eighth, ninth, tenth, and eleventh working modes.

[0146] like Figure 6 The bold line shown represents the fluid flow path in the fifth operating mode. In the fifth operating mode, the crew compartment requires heating while battery 10 does not; therefore, heater 11 is used for heating. In response to the command for the fifth operating mode, the refrigerant circuit and the battery circuit exchange heat, the second refrigerant sub-circuit is disconnected, the first refrigerant sub-circuit is circulated, the third battery sub-circuit is circulated, and the first, second, and fourth battery sub-circuits are disconnected.

[0166] Unlike Embodiment Nine, in response to commands for the first to third operating modes, both the heating circuit and the battery circuit are connected. The ability of the heater core 2 to exchange heat with the passenger compartment is controlled by adjusting the temperature damper within the air conditioning unit. For example, in the third operating mode, the temperature damper within the air conditioning unit prevents airflow in the heater core 2 from flowing into the mixing chamber. In response to the first and second operating modes, airflow in the heater core 2 flows into the mixing chamber.

[0167] Specifically, in response to commands for the first to third operating modes, the first heating sub-circuit is cyclically activated.

[0170] In response to the eighth operating mode, the second heating sub-circuit is circulated, only the fourth battery sub-circuit in the battery circuit is circulated, and the first electric drive sub-circuit is circulated.

[0171] In response to the ninth working mode, the second heating sub-circuit is circulated, only the fourth battery sub-circuit is circulated in the battery circuit, and the airflow in the warm air core 2 does not flow to the mixing chamber.
