[0058] This application provides a thermal management system, which will be described in detail below with reference to the accompanying drawings.

[0059] Reference Figure 1 The diagram shows a structural schematic of a thermal management system provided in an embodiment of this application. (Refer to...) Figure 2 The diagram shows a schematic representation of the structure of the heating core provided in an embodiment of this application.

[0060] like Figure 1 As shown, this application provides a thermal management system, including: a heater core 30, an engine radiator 110, and a first heat exchange module 130. The first heat exchange module 130 is used for thermally connecting with the vehicle's electric drive assembly and / or electronic control module. The heater core 30 includes a first heat dissipation part 301 and a second heat dissipation part 302 that are thermally connected. The first heat dissipation part 301 is connected to the first heat exchange module 130 and is used to circulate a first heat exchange medium. The second heat dissipation part 302 is connected to the engine radiator 110 and is used to circulate a second heat exchange medium.

[0061] In this embodiment, the heater core 30 includes a first heat dissipation section 301 and a second heat dissipation section 302 connected by thermal conductivity. The first heat dissipation section 301 is connected to the first heat exchange module 130, and the second heat dissipation section 302 is connected to the engine radiator 110. Thus, when the engine is not running, the engine radiator 110 can provide auxiliary cooling for the electric drive assembly and / or electronic control module through heat exchange between the first heat exchange medium flowing through the first heat exchange medium of the first heat dissipation section 301 and the second heat exchange medium flowing through the second heat exchange medium of the second heat dissipation section 302. In other words, the thermal management system of this embodiment can reuse the engine radiator 110, which not only improves the heat dissipation effect of the electric drive assembly and / or electronic control module but also effectively reduces the vehicle's operating and maintenance costs.

[0062] It should be noted that the specific types of the first and second heat exchange media are not limited in the embodiments of this application, and those skilled in the art can make adjustments according to actual needs. In one embodiment, the first and second heat exchange media can be water. Furthermore, the electric drive assembly includes a motor and / or a reducer, and the electronic control module includes modules for controlling motor drive, voltage regulation, and AC / DC conversion, etc.

[0063] Furthermore, such as Figure 2As shown, the first heat dissipation section 301 of the heater core 30 includes a first liquid inlet pipe 3011, a first liquid outlet pipe 3012, and a plurality of first flow channel plates 3013. The liquid inlet of the first flow channel plate 3013 is connected to the first liquid inlet pipe 3011, and the liquid outlet of the first flow channel plate 3013 is connected to the first liquid outlet pipe 3012, so that the first heat exchange medium enters the first flow channel plate 3013 from the first liquid inlet pipe 3011, and after heat exchange, is discharged from the first flow channel plate 3013 to the first liquid outlet pipe 3012. The inlet of the first liquid inlet pipe 3011 is connected to the outlet of the compressor 10, and the outlet of the first liquid outlet pipe 3012 is connected to the inlet of the evaporator 20 and the inlet of the first heat exchange module 130. The second heat dissipation section 302 includes a second liquid inlet pipe 3021, a second liquid outlet pipe 3022, and a plurality of second flow channel plates 3023. The liquid inlet of the second flow channel plate 3023 is connected to the second liquid inlet pipe 3021, and the liquid outlet of the second flow channel plate 3023 is connected to the second liquid outlet pipe 3022, so that the second heat exchange medium enters the second flow channel plate 3023 from the second liquid inlet pipe 3021, and after heat exchange, is discharged from the second flow channel plate 3023 to the second liquid outlet pipe 3022. One of the inlet of the first liquid inlet pipe 3011 or the outlet of the first liquid storage tank 210 is connected to the second heat exchange module 140, and the other is connected to the first water pump 160. Furthermore, the first flow channel plate 3013 and the second flow channel plate 3023 are alternately arranged to improve the heat exchange efficiency of the first heat dissipation section 301 and the second heat dissipation section 302.

[0064] In some alternative embodiments of this application, such as Figure 1 As shown, the thermal management system further includes: a second heat exchange module 140, which is used for thermal connection with the vehicle's engine; the second heat exchange module 140 is arranged in parallel with the engine radiator 110 and connected to the second heat dissipation section 302 so that the second heat exchange medium flows to the second heat exchange module 140 and exchanges heat with the second heat exchange module 140.

[0065] In this embodiment, a second heat exchange module 140 is provided and connected to the second heat dissipation unit 302. Thus, when it is predicted that the engine will need to be started during a future trip, the heat generated by the electric drive assembly and / or the electronic control module can be transferred to the second heat exchange module 140 through heat exchange between the electric drive assembly and / or the electronic control module and the first heat exchange medium, the first heat exchange medium and the second heat exchange medium, and the second heat exchange medium and the second heat exchange module 140. This preheating of the engine helps reduce energy consumption.

[0066] In some optional embodiments of this application, the thermal management system further includes a first three-way valve 180, which is disposed between the second heat exchange module 140, the engine radiator 110, and the second heat dissipation section 302. The first three-way valve 180 is used to connect the second heat exchange module 140 and the second heat dissipation section 302, and / or the second heat exchange module 140 and the engine radiator 110. Thus, by switching the first three-way valve 180, different engine thermal management conditions can be switched, such as switching between engine heating mode and engine cooling mode.

[0067] In some optional embodiments of this application, the thermal management system further includes a front compartment blower 120, which is used at least to provide auxiliary cooling for the engine radiator 110. This enhances the cooling effect of the engine radiator 110. In one embodiment, the front compartment blower 120 is located in the front compartment of the vehicle and is adjacent to the engine radiator 110.

[0068] In some optional embodiments of this application, the thermal management system further includes: a first water pump 160, which is disposed between the first heat dissipation section 301 and the first heat exchange module 130, and is used to drive the flow of the first heat exchange medium. Further, the thermal management system also includes: a second water pump 170, which is disposed between the second heat dissipation section 302 and the engine radiator 110, and is used to drive the flow of the second heat exchange medium.

[0069] In this embodiment of the application, since a first water pump 160 and a second water pump 170 are provided, the first water pump 160 can drive the first heat exchange medium to flow, thereby realizing the circulation of the first heat exchange medium, and the second water pump 170 can drive the second heat exchange medium to flow, thereby realizing the circulation of the second heat exchange medium, and thus realizing the transfer of heat.

[0070] In some optional embodiments of this application, the thermal management system further includes a third heat exchange module 150, which is used for thermally connecting to the vehicle's battery pack. The third heat exchange module 150 includes a first heat exchange section and a second heat exchange section that are thermally connected. The first heat exchange section is connected to the first heat dissipation section 301 and the first heat exchange module 130, respectively. The second heat exchange section is used to circulate a third heat exchange medium. The temperature regulation of the first heat exchange module 130 and the third heat exchange module 150 is achieved through heat exchange between the third heat exchange medium and the first heat exchange medium. The third heat exchange medium includes, but is not limited to, R410A, which is a mixture of difluoromethane and pentafluoroethane.

[0071] In this embodiment, a third heat exchange module 150 is provided, comprising a first heat exchange section and a second heat exchange section, wherein the first heat exchange section is connected to the first heat dissipation section 301 and the first heat exchange module 130. Thus, during the cooling operation of the electric drive assembly and / or the electronic control module, the temperature of the electric drive assembly and / or the electronic control module can be further reduced through heat exchange between the third heat exchange medium and the first heat exchange medium, between the first heat exchange medium and the first heat exchange module 130, and between the first heat exchange module 130 and the electric drive assembly and / or the electronic control module, thereby providing auxiliary heat dissipation.

[0072] It should be noted that the third heat exchange module 150 can be a battery composite cold plate, i.e., a combination of a direct cooling plate and a water cooling plate. The first heat exchange section can be a water cooling plate, and the second heat exchange section can be a direct cooling plate. Battery composite cold plates are existing technology, and the specific structure and working principle of the battery composite cold plate will not be elaborated upon in this embodiment.

[0073] In some optional embodiments of this application, the thermal management system further includes a second three-way valve 190, which is disposed between the first heat dissipation section 301, the first heat exchange section, and the first heat exchange module 130. The second three-way valve 190 is used to connect the first heat dissipation section 301 with the first heat exchange section and / or the first heat exchange module 130. Thus, by switching the second three-way valve 190, different thermal management conditions of the electric drive assembly and / or the electronic control module can be switched. These different thermal management conditions include: a condition where the engine radiator 110 exchanges heat with the electric drive assembly and / or the electronic control module, or a condition where both the engine radiator 110 and the third heat exchange module 150 exchange heat with the electric drive assembly and / or the electronic control module.

[0074] In some optional embodiments of this application, the thermal management system further includes a first heater 200, which is used to raise the temperature of the battery pack. The first heater 200 may be a heating film, which is thermally connected to the battery pack. Thus, when the heating rate of the battery pack is insufficient, the first heater 200 can be activated for auxiliary heating, thereby improving the heating efficiency of the battery pack.

[0075] In some optional embodiments of this application, the thermal management system further includes: a compressor 10 and a condenser 60 connected to each other; the inlet of the second heat exchange section is connected to the outlet of the condenser 60, and the outlet of the second heat exchange section is connected to the inlet of the compressor 10. Thus, by exchanging heat with the battery pack through the third heat exchange medium flowing through the second heat exchange section, the temperature of the battery pack can be reduced, achieving cooling of the battery pack. Furthermore, when the compressor 10 has sufficient compression power, heat exchange can be conducted through the third heat exchange medium with the first heat exchange medium, the first heat exchange medium with the first heat exchange module 130, and the first heat exchange module 130 with the electric drive assembly and / or the electronic control module. This can further reduce the temperature of the electric drive assembly and / or the electronic control module, playing an auxiliary heat dissipation role and further improving the cooling effect of the electric drive assembly and / or the electronic control module.

[0076] In some optional embodiments of this application, the thermal management system further includes an evaporator 20, the inlet of which is connected to the outlet of the condenser 60, and the outlet of which is connected to the inlet of the compressor 10. The evaporator 20 is used to reduce the temperature of the vehicle's passenger compartment. It should be noted that both the evaporator 20 and the heater core 30 are housed within the air conditioning unit. Specifically, the air conditioning unit has at least two chambers, each with an intake and exhaust passage connected to it. The evaporator 20 and the heater core 30 are located in different chambers. The air conditioning unit is also connected to a damper assembly, which controls the connection between the chambers and their corresponding intake and / or exhaust passages, thereby enabling intake and exhaust.

[0077] In this embodiment, because an evaporator 20 is provided, the temperature of the gas can be reduced through heat exchange between the third heat exchange medium flowing through the evaporator 20 and the gas flowing through the evaporator 20. Thus, by delivering the cooled gas from the exhaust channel to the crew compartment, cooling of the crew compartment can be achieved.

[0078] In some optional embodiments of this application, the thermal management system further includes a first expansion valve 70, which is disposed between the outlet of the condenser 60 and the inlet of the second heat exchange section. The first expansion valve 70 is used to control the flow rate and / or velocity of the third heat exchange medium flowing through the second heat exchange section. This allows the third heat exchange medium with a preset flow rate and / or preset velocity to exchange heat with the third heat exchange module 150, thereby enabling precise adjustment of the temperature of the third heat exchange module 150 and achieving precise regulation of the battery pack temperature.

[0079] In some optional embodiments of this application, the thermal management system further includes a second expansion valve 80, which is disposed between the outlet of the condenser 60 and the inlet of the evaporator 20. The second expansion valve 80 is used to control the flow rate and / or velocity of the third heat exchange medium flowing through the evaporator 20. This allows the third heat exchange medium with a preset flow rate and / or preset velocity to exchange heat with the gas outside the evaporator 20, thereby enabling precise adjustment of the gas temperature and achieving precise regulation of the cabin temperature.

[0080] This application embodiment does not limit the operating states of the first expansion valve 70 and the second expansion valve 80; those skilled in the art can configure them according to actual needs. For automated control, the first expansion valve 70 and the second expansion valve 80 can be electronic expansion valves. Furthermore, the thermal management system also includes a third expansion valve 90, which is located at the outlet of the third heat exchange module 150. That is, expansion valves are installed at both the inlet and outlet of the third heat exchange module 150, thereby further improving control accuracy and optimizing energy efficiency. The thermal management system also includes a one-way valve 100, which is located at the outlet of the third heat exchange module 150 and is used to guide the third heat exchange medium to flow unidirectionally within the third heat exchange module 150.

[0081] In some optional embodiments of this application, the thermal management system further includes a one-way valve 100, which is disposed between the outlet of the second heat exchange section and the inlet of the compressor 10. The one-way valve 100 is used to guide the third heat exchange medium to flow in one direction. This effectively prevents the third heat exchange medium from flowing back, ensures the stable operation of the thermal management system, and improves the cooling efficiency of the battery pack.

[0082] In some optional embodiments of this application, the thermal management system further includes an air conditioning blower 50, which is used to assist in cooling the evaporator 20 and / or to assist in heat dissipation from the heating core 30. Further, the air conditioning blower 50 may be disposed within the cavity of the air conditioning unit.

[0083] In this embodiment, the air conditioning blower 50 enhances the cooling effect of the evaporator 20 and the heat dissipation effect of the heater core 30. Simultaneously, the air conditioning blower 50 also provides power for gas flow, promoting gas circulation.

[0084] In some optional embodiments of this application, the thermal management system further includes a second heater 40, which is disposed adjacent to the warm air core 30. The second heater 40 is used to at least raise the temperature of the first heat exchange medium and / or the second heat exchange medium flowing through the warm air core 30. The second heater 40 may be a PTC heater (Positive Temperature Coefficient Heater), and the second heater 40 and the warm air core 30 are disposed in the same chamber of the air conditioning unit.

[0085] In this embodiment, a second heater 40 is provided and is arranged adjacent to the heater core 30. Thus, when the heater core 30 is insufficient in heating, the second heater 40 can be activated to provide auxiliary heating to the gas, further increasing the gas temperature and thereby improving the heating effect of the passenger compartment.

[0086] In addition, the thermal management system also includes a liquid storage tank 210 and sensors, etc. The liquid storage tank 210 is located at the outlet of the heater core 30 and is mainly used to store and regulate the flow rate of the first heat exchange medium. Sensors are used to acquire temperature and / or pressure information of the heat exchange medium (including the first and second heat exchange media). Sensors include, but are not limited to, temperature sensors, pressure sensors, and pressure-temperature sensors. This application does not limit the type or location of the sensors; those skilled in the art can configure them according to actual needs.

[0087] Combination Figure 1 and Figure 2 The following describes in detail the different operating conditions of the thermal management system according to the embodiments of this application.

[0088] 1. In pure electric mode, the temperature of the second heat exchange medium is approximately below 45℃.

[0089] (1) First cooling condition of battery pack

[0090] When the temperature of the first heat exchange medium is low (e.g., below 25°C) and can cool the battery pack, the first water pump 160 is activated, and the second three-way valve 190 switches to connect the first heat dissipation section 301 with the first heat exchange section. Cooling of the battery pack is achieved through heat exchange between the first heat exchange medium and the first heat exchange section, and between the first heat exchange section and the battery pack. If cooling is insufficient, the air conditioning blower 50 can be turned on to allow the gas to exchange heat with the first heat exchange medium flowing through the warm air core 30, thereby lowering the temperature of the first heat exchange medium and further improving the cooling effect of the battery pack. Simultaneously, the heated gas can be discharged to the outside atmosphere or the passenger compartment as needed.

[0091] (2) The second cooling condition of the battery pack

[0092] When the temperature of the first heat exchange medium is too high (e.g., above 38°C) and cannot cool the battery pack, the second three-way valve 190 is switched to connect the first heat dissipation section 301 with the first heat exchange module 130. Then, the compressor 10 is started to cool the battery pack.

[0093] (3) The first heating condition of the battery pack

[0094] If the temperature of the first heat exchange medium is high enough to heat the battery pack, the first water pump 160 is activated, and the second three-way valve 190 switches to connect the first heat dissipation unit 301 with the first heat exchange unit. Heating of the battery pack is achieved through heat exchange between the first heat exchange medium and the first heat exchange unit, and between the first heat exchange unit and the battery pack. During this process, if the passenger compartment requires heating, the air conditioning blower 50 can be turned on to allow the gas to exchange heat with the first heat exchange medium flowing through the warm air core 30, thereby raising the gas temperature and discharging it into the passenger compartment. If the battery pack heating rate is insufficient, the first heater 200 can be activated; if the passenger compartment heating rate is insufficient, the second heater 40 can be activated.

[0095] (4) The second heating condition of the battery pack

[0096] If the temperature of the first heat exchange medium is too low to heat the battery pack, the second three-way valve 190 is switched to connect the first heat dissipation section 301 to the first heat exchange module 130. Then, the first heater 200 is activated to heat the battery pack.

[0097] (5) First cooling condition of electric drive assembly and / or electronic control module

[0098] The first water pump 160 is started, and the second three-way valve 190 is switched to connect the first heat dissipation unit 301 to the first heat exchange module 130. Heat dissipation is achieved using the heater core 30, i.e., heat exchange occurs between the gas and the first heat exchange medium flowing through the heater core 30, thereby reducing the temperature of the first heat exchange medium and cooling the electric drive assembly and / or the electronic control module. Simultaneously, the heated gas can be discharged to the outside atmosphere or the passenger compartment as needed. During this process, the air conditioning blower 50 can be activated as needed for auxiliary heat dissipation, and the heated gas can be discharged to the outside atmosphere or the passenger compartment as needed.

[0099] (6) Second cooling condition for electric drive assembly and / or electronic control module

[0100] Start the first water pump 160 and switch the second three-way valve 190 to connect the first heat dissipation section 301 and the first heat exchange module 130. Start the second water pump 170 and switch the first three-way valve 180 to connect the second heat exchange module 140 to the second heat dissipation section 302 and the engine radiator 110. Heat dissipation and heat exchange are achieved using the heater core 30. On one hand, heat exchange occurs between the gas and the first heat exchange medium flowing through the heater core 30, thereby reducing the temperature of the first heat exchange medium. On the other hand, heat exchange occurs between the engine radiator 110 and the second heat exchange medium, and between the second and first heat exchange medium, further reducing the temperature of the first heat exchange medium, thus cooling the electric drive assembly and / or the electronic control module. During this process, the air conditioning blower 50 can be turned on as needed for auxiliary cooling, and the heated gas can be discharged to the outside atmosphere or the passenger compartment as needed. The front cabin blower 120 can also be turned on for forced cooling as needed.

[0101] (7) The third cooling condition of the electric drive assembly and / or electronic control module

[0102] When the electric drive assembly and / or electronic control module heats up too quickly, and the compressor 10 has sufficient power margin, the first water pump 160 is activated, switching the second three-way valve 190 to the first heat dissipation section 301, simultaneously connecting it to the first heat exchange section and the first heat exchange module 130. On one hand, the compressor 10 is activated to cool the battery pack, reducing the temperature of the first heat exchange medium through heat exchange between the first and second heat exchange media; on the other hand, the heater core 30 is used for external heat exchange, i.e., heat exchange between the gas and the first heat exchange medium flowing through the heater core 30, thereby further reducing the temperature of the first heat exchange medium and achieving cooling of the electric drive assembly and / or electronic control module.

[0103] (8) Engine preheating condition

[0104] Start the second water pump 170 and switch the first three-way valve 180 to connect the second heat exchange module 140 and the second heat dissipation unit 302. Start the first water pump 160 and switch the second three-way valve 190 to connect the first heat dissipation unit 301 and the first heat exchange module 130. Heat exchange is achieved using the heater core 30, specifically the heat exchange between the first and second heat exchange media, and between the second heat exchange media and the second heat exchange module 140, thus preheating the engine.

[0105] Second, in hybrid mode, the temperature of the second heat exchange medium is approximately higher than 45℃.

[0106] (1) Cooling conditions of the battery pack

[0107] Switch the second three-way valve 190 to connect the first heat dissipation section 301 with the first heat exchange module 130. Then, start the compressor 10 to cool the battery pack.

[0108] (2) Heating conditions of the battery pack

[0109] Start the first water pump 160 and switch the second three-way valve 190 to connect the first heat dissipation unit 301 and the first heat exchange module 130. Start the second water pump 170 and switch the first three-way valve 180 to connect the second heat exchange module 140 and the second heat dissipation unit 302. Through heat exchange between the second heat exchange medium and the first heat exchange medium, and between the first heat exchange medium and the third heat exchange medium, the temperature of the third heat exchange medium can be increased, thereby heating the battery pack.

[0110] During this process, if the engine's heat dissipation is insufficient, the first three-way valve 180 can be switched to the second heat exchange module 140, which is simultaneously connected to the second heat dissipation unit 302 and the engine radiator 110, so that the engine can be cooled while the battery pack is heated.

[0111] (3) Engine cooling conditions

[0112] When the temperature of the second heat exchange medium is too high (e.g., above 130°C) and the compressor 10 has compression margin, the compressor 10 is started; the second water pump 170 is started, and the first three-way valve 180 is switched to the second heat exchange module 140, simultaneously connecting it to the second heat dissipation section 302 and the engine radiator 110; the first water pump 160 is started, and the second three-way valve 190 is switched to the first heat dissipation section 301, simultaneously connecting it to the first heat exchange section and the first heat exchange module 130. On one hand, the temperature of the first heat exchange medium can be reduced through heat exchange between the third heat exchange medium and the first heat exchange medium; on the other hand, the temperature of the first heat exchange medium can be further reduced through heat exchange between the gas and the first heat exchange medium flowing through the heater core 30. Through heat exchange between the first heat exchange medium and the second heat exchange medium, the temperature of the second heat exchange medium can be reduced, thereby achieving engine cooling. During this process, the air conditioning blower 50 can be turned on as needed for auxiliary cooling, and the heated gas can be discharged to the outside atmosphere or the passenger compartment as needed.

[0113] In summary, the thermal management system provided in this application has at least the following advantages:

[0114] In this embodiment, the heater core includes a first heat dissipation section and a second heat dissipation section connected by thermal conductivity. The first heat dissipation section is connected to a first heat exchange module, and the second heat dissipation section is connected to the engine radiator. Thus, when the engine is not running, the engine radiator can provide auxiliary cooling for the electric drive assembly and / or electronic control module through heat exchange between the first heat exchange medium flowing through the first heat dissipation section and the second heat exchange medium flowing through the second heat dissipation section. In other words, the thermal management system of this embodiment can reuse the engine radiator, which not only improves the heat dissipation effect of the electric drive assembly and / or electronic control module but also effectively reduces the vehicle's operating and maintenance costs.
