Description

Technical Field

[0001] This invention relates to the field of thermal management technology for new energy vehicles, specifically to a thermal management integrated module assembly and a vehicle. Background Technology

[0002] As the automotive industry continues its electrification transformation, the thermal management systems of new energy vehicles are becoming increasingly complex. Typically, new energy vehicles need to simultaneously manage battery coolant circuits, motor and electronic control coolant circuits, heater coolant circuits, and heat exchange circuits such as water-cooled evaporators and water-cooled condensers. In traditional new energy vehicle thermal management systems, to achieve heat coupling and distribution between multiple circuits such as the battery, motor and electronic control system, and heater, multiple three-way valves, four-way valves, or five-way valves are usually combined.

[0003] However, the aforementioned traditional solutions result in complex system piping and a large number of joints, which not only increases coolant flow resistance but also raises water pump power consumption. Furthermore, numerous pipe interfaces and valve connections are potential leak points, which may lead to decreased system reliability and compromised vehicle safety over long-term operation.

[0004] In low-temperature environments, the heating capacity of a heat pump system will significantly decrease. Especially in extremely low-temperature conditions, the heating capacity of a conventional heat pump cycle is insufficient, and PTC auxiliary heating is usually required to meet the heating needs of the passenger compartment and battery, which leads to increased vehicle energy consumption and affects winter range.

[0005] Existing technologies include integrated thermal management modules that utilize a nine-way water valve, a coolant connecting plate, and a valve island to integrate parts of the water-side and refrigerant-side circuits. While these solutions can reduce the number of pipes and heat loss in the vehicle to some extent, they still have the following drawbacks:

[0006] First, regarding water-side integration, the existing nine-way valve solution has limited operating modes and struggles to achieve a series heating mode between the battery coolant circuit and the heater coolant circuit. When both the battery and the passenger compartment require heating, it is often necessary to increase the power and operating time of the air PTC, leading to increased energy consumption.

[0007] Second, in terms of water-side and refrigerant-side coupling, the existing solutions typically have relatively independent water-side and refrigerant-side loops with insufficient coupling depth. This makes it impossible to fully utilize the water-cooled condenser, heat pump system, and waste heat from electric drive to provide coordinated heating for the battery and crew compartment, resulting in low heat source utilization and significant heat loss.

[0008] Third, in terms of refrigerant-side integration, existing solutions often require numerous shut-off valves, check valves, or independent heat exchanger assemblies, resulting in complex structures, high material costs, and significant control difficulties. Furthermore, existing solutions typically do not fully integrate hot gas bypass circuits and gas-liquid separator heating structures, leading to slow compressor discharge temperature rise and slow refrigerant pressure build-up during extremely low-temperature startup, resulting in delayed heating response. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the purpose of this invention is to provide a thermal management integrated module assembly and vehicle that features high integration, simplified piping, flexible control, and low energy consumption, thereby meeting the needs of new energy vehicles in low-temperature heating, high-temperature cooling, high-rate fast charging heat dissipation, and platform-based deployment.

[0074] Example 1

[0075] like Figures 1 to 3 As shown, this embodiment provides a thermal management integrated module assembly. This thermal management integrated module assembly mainly includes a flow channel substrate 1, a ten-way water valve 1310, a first three-way proportional valve 1305, a second three-way proportional valve 1405, a first electronic water pump 1301, a second electronic water pump 1401, a third electronic water pump 1501, a one-way valve 1406, a water temperature sensor 1505, a first electronic expansion valve 1104, a second electronic expansion valve 1106, a third electronic expansion valve 1117, a first temperature and pressure sensor 1102, a second temperature and pressure sensor 1111, a water-cooled evaporator 1109, a water-cooled condenser 1103, a gas-liquid separator 1116, and a gas-liquid separator electric heater 1118.

[0076] The ten-way water valve 1310 is used to control the switching of the water-side thermal management mode. The first three-way proportional valve 1305 is used to adjust the coolant flow ratio between the electric drive coolant circuit and the heater coolant circuit, and the second three-way proportional valve 1405 is used to adjust the coolant flow ratio between the battery coolant circuit and the heater coolant circuit. The first electronic water pump 1301, the second electronic water pump 1401, and the third electronic water pump 1501 are used to drive the coolant circulation in the corresponding water-side circuits.

[0077] like Figure 4 As shown, the flow channel base plate 1 includes a water-side flow channel plate 10, an intermediate partition plate 11, and a refrigerant-side flow channel plate 12. The water-side flow channel plate 10 is mainly used for mounting water-side components, including... Figure 2The diagram shows a ten-way water valve 1310, a first electronic water pump 1301, a second electronic water pump 1401, a third electronic water pump 1501, a first three-way proportional valve 1305, and a second three-way proportional valve 1405. An intermediate partition 11 is disposed between the water-side flow channel plate 10 and the refrigerant-side flow channel plate 12, used to cooperate with the water-side flow channel plate 10 to seal the water-side flow channel, and to cooperate with the refrigerant-side flow channel plate 12 to seal the refrigerant-side flow channel. The refrigerant-side flow channel plate 12 is mainly used to install the water-cooled evaporator 1109, the water-cooled condenser 1103, the gas-liquid separator 1116, the gas-liquid electric heater 1118, the first electronic expansion valve 1104, the second electronic expansion valve 1106, and the third electronic expansion valve 1117.

[0078] like Figures 5 to 8 As shown, the ten-way water valve 1310 includes a first channel to a tenth channel. The first and second channels are used to connect to the battery coolant circuit and can be connected to an external battery coolant circuit via the first external flow channel port 2101 and the second external flow channel port 2102. The third and fourth channels are used to connect to the heater coolant circuit and can be connected to an external heater coolant circuit via the third external flow channel port 2103 and the fourth external flow channel port 2104. The fifth and sixth channels are used to connect to the water-cooled condenser coolant circuit and can be connected to an external water-cooled condenser coolant circuit via the fifth external flow channel port 2105 and the sixth external flow channel port 2106. The seventh and eighth channels are used to connect to the electric drive coolant circuit and can be connected to an external electric drive coolant circuit via the seventh external flow channel port 2107 and the eighth external flow channel port 2108. The ninth and tenth channels are used to connect to the water-cooled evaporator coolant circuit and can be connected to an external water-cooled evaporator coolant circuit via the ninth external flow channel port 2109 and the tenth external flow channel port 2110. The flow channel substrate 1 also includes an eleventh external flow channel cavity 2111, which is used to cooperate with the seventh external flow channel cavity 2107 to form a short-circuit flow path for a low-temperature heat sink in the electric drive coolant circuit heat storage mode.

[0079] The water-cooled evaporator 1109 is connected to the flow channel substrate 1 and is connected to the refrigerant circuit and the water-cooled evaporator coolant circuit. It is used to cool the battery coolant circuit and / or the heater coolant circuit by absorbing heat through refrigerant evaporation. The water-cooled condenser 1103 is connected to the flow channel substrate 1 and is connected to the refrigerant circuit and the water-cooled condenser coolant circuit. It is used to heat the battery coolant circuit and / or the heater coolant circuit by releasing heat through refrigerant condensation.

[0080] like Figure 9As shown, the refrigerant-side thermal management component includes a refrigerant circulation evaporation and condensation circuit and a hot gas bypass circuit. The refrigerant-side flow channel plate 12 is provided with a first refrigerant channel 31, a second refrigerant channel 32, a third refrigerant channel 33, a fourth refrigerant channel 34, a fifth refrigerant channel 35, and a sixth refrigerant channel 36. Specifically, the first refrigerant passage 31 to the sixth refrigerant passage 36 cooperate with the water-cooled evaporator 1109, the water-cooled condenser 1103, and the gas-liquid separator 1116 to form a refrigerant circulation evaporation and condensation circuit; at least one of the first refrigerant passage 31 and the second refrigerant passage 32 cooperates with the first refrigerant flow channel opening 3101 and / or the second refrigerant flow channel opening 3102 to connect to the external compressor; at least one of the third refrigerant passage 33, the fourth refrigerant passage 34, and the fifth refrigerant passage 35 cooperates with the third refrigerant flow channel opening 3103, the fourth refrigerant flow channel opening 3104, and / or the fifth refrigerant flow channel opening 3105 to connect to the external evaporator; the sixth refrigerant passage 36 is connected to at least a portion of the first refrigerant passage 31 to the fifth refrigerant passage 35 so that the refrigerant can circulate among the external compressor, the water-cooled condenser 1103, the water-cooled evaporator 1109, the external evaporator, and the gas-liquid separator 1116.

[0081] The hot gas bypass circuit includes a third electronic expansion valve 1117 and a gas-liquid separator 1116. The third electronic expansion valve 1117 is connected to the gas-liquid separator 1116 and is connected to an external compressor through the first refrigerant flow channel port 3101 and the second refrigerant flow channel port 3102. Thus, during low-temperature or ultra-low-temperature start-up, the high-temperature refrigerant discharged from the compressor can enter the gas-liquid separator 1116 through the hot gas bypass circuit, assisting the compressor in quickly building up pressure and improving the heating response speed.

[0082] Furthermore, a gas-liquid separator electric heater 1118 can be installed on the gas-liquid separator 1116. The gas-liquid separator electric heater 1118 is used to heat the gas-liquid separator 1116 during ultra-low temperature start-up, so that the refrigerant side system can reach a stable working state more quickly, thereby improving the low-temperature heating capacity.

[0083] like Figures 9 to 12As shown, the ten-way water valve 1310 can establish different connections between multiple water-side circuits by switching the valve core position, thereby realizing series, independent circulation or short-circuit heat storage between the battery coolant circuit, electric drive coolant circuit, heater coolant circuit, water-cooled evaporator coolant circuit and water-cooled condenser coolant circuit. Specifically, the ten-way water valve 1310 includes a first channel to a tenth channel, wherein the first channel and the first flow channel cavity 101, the second channel and the second flow channel cavity 102 are used to connect to the battery coolant circuit; the third channel and the third flow channel cavity 103, the fourth channel and the fourth flow channel cavity 104 are used to connect to the heater coolant circuit; the fifth channel and the fifth flow channel cavity 105, the sixth channel and the sixth flow channel cavity 106 are used to connect to the water-cooled condenser coolant circuit; the seventh channel and the seventh flow channel cavity 107, the eighth channel and the eighth flow channel cavity 108 are used to connect to the electric drive coolant circuit; and the ninth channel and the ninth flow channel cavity 109, the tenth channel and the tenth flow channel cavity 110 are used to connect to the water-cooled evaporator coolant circuit.

The flow channel substrate 1 is also provided with an eleventh external flow channel port 2111, which is used to cooperate with the seventh external flow channel port 2107 to form a short-circuit flow path for the low-temperature radiator in the heat storage mode of the electric drive coolant circuit.

[0085] Mode 1 is a series connection of the battery coolant circuit, the heater coolant circuit, and the water-cooled condenser coolant circuit. In this mode, the heat pump system can simultaneously heat the battery pack and the heater circuit, and adjust the coolant temperature entering the battery coolant circuit through the second three-way proportional valve 1405 to meet the different inlet water temperature requirements of the battery coolant circuit and the heater coolant circuit. The structural arrangement of this mode is as follows: the first channel and first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and second electronic water pump flow channel cavity 5101, the second three-way proportional valve 1405, the second channel and second flow channel cavity 102, the third channel and third flow channel cavity 103, the fourth channel and fourth flow channel cavity 104, the fifth channel and fifth flow channel cavity 105, the third electronic water pump 1501 and third electronic water pump flow channel cavity 5102, and the sixth channel and sixth flow channel cavity 106 are sequentially connected; and the external battery coolant circuit, the external heater coolant circuit, and the external water-cooled condenser coolant circuit are connected respectively through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, the third external flow channel cavity 2103 and the fourth external flow channel cavity 2104, and the fifth external flow channel cavity 2105 and the sixth external flow channel cavity 2106, thereby forming a series heating circuit.

[0086] Mode 2 is a series connection mode for the battery coolant circuit and the electric drive coolant circuit. Under normal operating conditions, this mode can utilize a low-temperature radiator system to cool the battery. The structural arrangement of this mode is as follows: the first channel and first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and second electronic water pump flow channel cavity 5101, the second channel and second flow channel cavity 102, the seventh channel and seventh flow channel cavity 107, the first electronic water pump 1301 and first electronic water pump flow channel cavity 5103, and the eighth channel and eighth flow channel cavity 108 are sequentially connected; and the external battery coolant circuit and the external electric drive coolant circuit are connected respectively through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, and the seventh external flow channel cavity 2107 and the eighth external flow channel cavity 2108, thereby forming a series cooling circuit.

[0087] Mode 3 is a series connection mode between the battery coolant circuit and the water-cooled evaporator coolant circuit. Under high-temperature conditions, this mode can utilize the refrigerant evaporation system to cool the battery pack. The structural arrangement of this mode is as follows: the first channel and first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and second electronic water pump flow channel cavity 5101, the second channel and second flow channel cavity 102, the ninth channel and ninth flow channel cavity 109, and the tenth channel and tenth flow channel cavity 110 are sequentially connected; and the external battery coolant circuit and the external water-cooled evaporator coolant circuit are respectively connected through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, and the ninth external flow channel cavity 2109 and the tenth external flow channel cavity 2110, thereby forming a series refrigeration circuit.

[0088] Mode 4 is an independent cooling mode for the electric drive coolant circuit. In this mode, the low-temperature radiator can independently cool the electric drive coolant circuit, allowing the heat generated by the electric drive system to be dissipated independently without affecting the battery coolant circuit and the heater coolant circuit. The structural arrangement of this mode is as follows: the seventh channel and seventh flow channel cavity 107 of the ten-way water valve 1310, the first electronic water pump 1301 and the first electronic water pump flow channel cavity 5103, and the eighth channel and eighth flow channel cavity 108 cooperate, and are connected to the external electric drive coolant circuit through the seventh external flow channel cavity 2107 and the eighth external flow channel cavity 2108, thereby forming an independent cooling cycle.

[0089] Mode 5 is a series connection mode for the battery coolant circuit and the heater coolant circuit. In this mode, the battery coolant circuit and the heater coolant circuit are connected in series, and the inlet water temperature entering the battery coolant circuit is adjusted by the second three-way proportional valve 1405 to meet the differentiated inlet water temperature requirements of the battery and the passenger compartment. The structural arrangement of this mode is as follows: the first channel and the first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and the second electronic water pump flow channel cavity 5101, the second three-way proportional valve 1405, the second channel and the second flow channel cavity 102, the third channel and the third flow channel cavity 103, and the fourth channel and the fourth flow channel cavity 104 are sequentially connected; and the external battery coolant circuit and the external heater coolant circuit are connected respectively through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, and the third external flow channel cavity 2103 and the fourth external flow channel cavity 2104, thus forming a series heating circuit.

[0090] Mode 6 is a series connection mode between the battery coolant circuit and the water-cooled condenser coolant circuit. In this mode, the heat pump system heats the battery coolant circuit through the water-cooled condenser 1103, which is suitable for operating conditions where the battery pack has heating requirements but the heating requirements of the warm air circuit are low or do not need to be involved. The structural connection of this mode is as follows: the first channel and the first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and the second electronic water pump flow channel cavity 5101, the second channel and the second flow channel cavity 102, the fifth channel and the fifth flow channel cavity 105, the third electronic water pump 1501 and the third electronic water pump flow channel cavity 5102, and the sixth channel and the sixth flow channel cavity 106 are connected in sequence; and the external battery coolant circuit and the external water-cooled condenser coolant circuit are connected through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, and the fifth external flow channel cavity 2105 and the sixth external flow channel cavity 2106, respectively, thus forming a series heating circuit.

[0091] Mode 7 is a series connection mode between the heater coolant circuit and the water-cooled condenser coolant circuit. In this mode, the heat pump system heats the heater coolant circuit through the water-cooled condenser 1103, which is suitable for operating conditions where there is a heating requirement in the passenger compartment but a low or no need for battery heating. The structural connection of this mode is as follows: the third channel and the third flow channel cavity 103, the fourth channel and the fourth flow channel cavity 104, the fifth channel and the fifth flow channel cavity 105 of the ten-way water valve 1310, the third electronic water pump 1501 and the third electronic water pump flow channel cavity 5102, and the sixth channel and the sixth flow channel cavity 106 are connected in sequence; and the external heater coolant circuit and the external water-cooled condenser coolant circuit are connected respectively through the third external flow channel cavity 2103 and the fourth external flow channel cavity 2104, and the fifth external flow channel cavity 2105 and the sixth external flow channel cavity 2106, thus forming a series heating circuit.

[0092] Mode 8 is a series connection mode between the electric drive coolant circuit and the heater coolant circuit. In this mode, the coolant flow ratio between the electric drive coolant circuit and the heater coolant circuit is adjusted by the first three-way proportional valve 1305, so that the waste heat generated by the electric drive system can be supplied to the heater coolant circuit, thereby heating the passenger compartment with the waste heat from the motor. The structural arrangement of this mode is as follows: the seventh channel and the seventh flow channel cavity 107 of the ten-way water valve 1310, the first electronic water pump 1301 and the first electronic water pump flow channel cavity 5103, the first three-way proportional valve 1305, the eighth channel and the eighth flow channel cavity 108, the third channel and the third flow channel cavity 103, and the fourth channel and the fourth flow channel cavity 104 are sequentially connected; and the external electric drive coolant circuit and the external heater coolant circuit are connected respectively through the seventh external flow channel cavity 2107 and the eighth external flow channel cavity 2108, and the third external flow channel cavity 2103 and the fourth external flow channel cavity 2104, thus forming a series waste heat heating circuit.

[0093] Mode 9 is a series connection of the battery coolant circuit, the heater coolant circuit, and the water-cooled evaporator coolant circuit. Under high-temperature conditions, this mode can simultaneously cool or refrigerate the battery pack and the heater coolant circuit through the refrigerant evaporation system. The structural arrangement of this mode is as follows: the first channel and first flow channel cavity 101 of the ten-way water valve 1310, the second electronic water pump 1401 and second electronic water pump flow channel cavity 5101, the second channel and second flow channel cavity 102, the third channel and third flow channel cavity 103, the fourth channel and fourth flow channel cavity 104, the ninth channel and ninth flow channel cavity 109, and the tenth channel and tenth flow channel cavity 110 are sequentially matched; and the external battery coolant circuit, the external heater coolant circuit, and the external water-cooled evaporator coolant circuit are connected respectively through the first external flow channel cavity 2101 and the second external flow channel cavity 2102, the third external flow channel cavity 2103 and the fourth external flow channel cavity 2104, and the ninth external flow channel cavity 2109 and the tenth external flow channel cavity 2110, thereby forming a series refrigeration circuit.

[0094] Mode 10 is the electric drive coolant circuit heat storage mode. In this mode, the low-temperature radiator is short-circuited, and the electric drive coolant circuit does not dissipate heat through the low-temperature radiator, thus retaining the heat in the electric drive coolant circuit and achieving heat storage in the electric drive circuit. The structural arrangement of this mode is as follows: the seventh channel and seventh flow channel cavity 107 of the ten-way water valve 1310, the first electronic water pump 1301 and the first electronic water pump flow channel cavity 5103, the first three-way proportional valve 1305, the eighth channel and the eighth flow channel cavity 108 cooperate, and are connected to the eleventh external flow channel cavity 2111 through the seventh external flow channel cavity 2107, thereby short-circuiting the low-temperature radiator and forming a heat storage cycle in the electric drive coolant circuit. It should be noted that when the second three-way proportional valve 1405 participates in this short-circuited flow path in the actual pipeline layout, the above flow path switching can also be achieved by the second three-way proportional valve 1405.

[0095] Through the aforementioned ten operating modes, the ten-way water valve 1310 can switch the water-side loop connection relationship under different ambient temperatures, battery temperatures, electric drive temperatures, crew cabin heat demands, fast charging heat dissipation demands, and refrigerant system conditions, realizing heat coupling and distribution between the battery, electric drive, heater, water-cooled evaporator, and water-cooled condenser. Figure 12 As shown, different valve core positions correspond to different flow channel structures of the ten-way water valve 1310, thereby supporting the switching of the above ten water-side operating modes. Compared with solutions combining multiple three-way valves, four-way valves, or five-way valves, this embodiment can reduce the number of external connection pipes and joints, reduce coolant flow resistance, water pump power consumption, and leakage risk, and improve low-temperature heating, high-temperature cooling, and overall vehicle energy utilization efficiency through battery and heater series heating, electric drive waste heat utilization, water-cooled condenser heating, and water-cooled evaporator cooling modes.

[0098] When the vehicle starts in low temperatures, the battery coolant circuit and / or heater coolant circuit can be heated by the water-cooled condenser 1103, and the refrigerant system can be pressurized quickly by the hot gas bypass circuit and the gas distribution electric heater 1118, thereby shortening the warm-up time of the passenger compartment and reducing the PTC auxiliary heating power and working time.

[0099] When the vehicle is in high-temperature or fast-charging conditions, the battery coolant circuit can be cooled by the water-cooled evaporator 1109, or the battery coolant circuit and the water-cooled evaporator coolant circuit can be connected in series by the ten-way water valve 1310 to achieve rapid cooling of the battery.

[0100] When the vehicle is in a working condition where the waste heat from the electric drive can be utilized, the electric drive coolant circuit and the heater coolant circuit can be switched in series via the ten-way water valve 1310, and the flow ratio can be adjusted via the first three-way proportional valve 1305 to introduce the waste heat from the electric drive into the heater circuit, thereby reducing the overall energy consumption of the vehicle.

[0101] Therefore, the vehicle in this embodiment can achieve efficient thermal coupling between the battery, electric drive, heating and refrigerant systems under different ambient temperatures and different vehicle operating conditions, thereby improving thermal management efficiency, reducing energy consumption, and enhancing winter range.
