[0086] Reference Figure 1 In an embodiment of the present application, a vehicle thermal management system is provided, the system architecture of which includes a refrigerant circulation system and a coolant circulation system.

[0089] The HVAC assembly includes a blower 15 , a cold air core 16 and a warm air core 17 ; the front-end module includes a radiator 18 and a cooling fan 19 .
[0090] Of course, the coolant circulation system should also include the first electronic water pump 7 to the third electronic water pump 9 .
[0091] Among them, the inlet of the electric drive module 20 is connected to the second valve port of the nine-way valve 12 and the outlet of the radiator 18 of the HVAC assembly, the inlet of the radiator 18 of the HVAC assembly is connected to the first valve port of the nine-way valve 12, the outlet of the electric drive module 20 is connected to the third valve port of the nine-way valve 12, the outlet of the battery 21 is connected to the fifth valve port of the nine-way valve 12 and the inlet of the one-way valve 13, the inlet of the battery 21 is connected to the outlet of the third electronic water pump 9, the inlet of the third electronic water pump 9 is connected to the fourth valve port of the nine-way valve 12, the inlet of the second electronic water pump 8 is connected to the seventh valve port of the nine-way valve 12, the outlet of the second electronic water pump 8 is connected to the coolant inlet of the water-cooled evaporator 6, the coolant outlet of the water-cooled evaporator 6 is connected to the third interface of the second three-way valve 11, and the second three-way valve The second interface of 11 is connected to the cold air core 16 inlet of the HVAC assembly, the cold air core 16 outlet of the HVAC assembly is connected to the inlet of the second electronic water pump 8, the first interface of the second three-way valve 11 is connected to the sixth valve port of the nine-way valve 12, the first interface of the first three-way valve 10 is connected to the eighth valve port of the nine-way valve 12, the second interface of the first three-way valve 10 is connected to the warm air core 17 inlet of the HVAC assembly, the warm air core 17 outlet of the HVAC assembly is connected to the inlet of the first electronic water pump 7, the coolant outlet of the water-cooled condenser 2 is connected to the third interface of the first three-way valve 10, the ninth interface of the first three-way valve 10 is connected to the inlet of the first electronic water pump 7, and the outlet of the first electronic water pump 7 is connected to the coolant inlet of the water-cooled condenser 2.
[0092] The coolant circulation system and the refrigerant circulation system are coupled by the water-cooled condenser 2 and the water-cooled evaporator 6. The coolant exchanges heat with the refrigerator through the water-cooled condenser 2 and the water-cooled evaporator 6, and the temperature is increased or decreased by using the radiator 18 of the front-end module, thereby meeting the needs of the HVAC assembly, the electric drive module 20 and the battery 21 in different scenarios.
[0093] Reference Figure 2 、 Figures 13 to 16Based on the aforementioned vehicle thermal management system, the embodiment of the present application provides a vehicle thermal management integrated system, including: a refrigerant side integrated component and a coolant side integrated component; the refrigerant side integrated component includes an integrated refrigerant flow channel plate, a compressor 1, a water-cooled condenser 2, a liquid storage tank 3, a first electronic expansion valve 4 and a water-cooled evaporator 6; the coolant side integrated component includes an integrated coolant flow channel plate, a nine-way valve 12, a first three-way valve 10, a second three-way valve 11, a first electronic water pump 7, a second electronic water pump 8, and a third electronic water pump 9; the coolant flow channel plate is fixed on the refrigerant flow channel plate; The refrigerant flow channel plate is provided with a refrigerant flow channel connected to the compressor 1, the refrigerant side of the water-cooled condenser 2, the liquid storage tank 3, the first electronic expansion valve 4 and the refrigerant side of the water-cooled evaporator 6; the coolant flow channel plate is provided with a coolant flow channel connected to the nine-way valve 12, the first three-way valve 10, the second three-way valve 11, the expansion kettle 14, the first electronic water pump, the second electronic water pump, the third electronic water pump, the coolant side of the water-cooled condenser 2 and the coolant side of the water-cooled evaporator 6. The coolant flow channel is also used to be connected to the vehicle's front-end module, electric drive module 20, battery 21 and HVAC assembly through pipelines.
[0094] The refrigerant-side integrated assembly integrates the compressor 1, water-cooled evaporator 6, water-cooled condenser 2, first electronic expansion valve 4, and second electronic expansion valve 5 through a refrigerant flow plate, eliminating all refrigerant piping designs and forming a refrigerant-side integrated assembly with the simplest structure. This refrigerant-side integrated assembly is isolated from the vehicle's front-end module and HVAC assembly, preventing refrigerant from entering the front-end module and HVAC assembly, avoiding the risk of refrigerant-induced combustion and improving safety. Because the refrigerant flow channels on the refrigerant flow plate serve as refrigerant pipelines, the elimination of refrigerant pipelines can reduce overall costs. Furthermore, the refrigerant flow channels are shorter than the original refrigerant pipelines, reducing the refrigerant charge. The refrigerant flow plate also allows for pre-filling of the refrigerant.
[0095] The traditional compressor connection method is to connect with air conditioning hoses, but hoses take up a lot of space and are prone to leakage over time. If the integration solution of the compressor and thermal management integrated module still uses hoses, it will not make much sense. Therefore, the embodiment of the present application adopts a solution in which the compressor 1 is directly connected to the refrigerant flow channel plate, which can reduce hose parts, reduce leakage and reduce costs.
[0096] For the coolant-side integrated component, it can realize the coolant circulation between the vehicle's front-end module, HVAC assembly, electric drive module 20 and battery 21 through ten pipes.
[0097] The refrigerant-side integrated components and the coolant-side integrated components together minimize the volume of the vehicle's thermal management components, which is beneficial to the platform development of the vehicle and facilitates vehicle assembly.
[0098] Reference Figures 3 to 6 The compressor 1 is assembled on one side surface of the refrigerant flow channel plate by screws, and the water-cooled condenser 2, the liquid storage tank 3, the first electronic expansion valve 4 and the water-cooled evaporator 6 are assembled on the other side surface of the refrigerant flow channel plate by screws; the inlet of the liquid storage tank 3 is arranged higher than the outlet of the liquid storage tank 3, and the liquid storage tank 3 adopts a top-in and bottom-out arrangement, which is beneficial to reducing the mass of the residual refrigeration oil in the liquid storage tank 3 and is beneficial to improving the oil circulation efficiency of the system.
[0099] Reference Figures 3 to 9 In the embodiment of the present application, the refrigerant flow channel provided on the refrigerant flow channel plate includes: a first flow channel 1011 provided on the refrigerant flow channel plate, one end of the first flow channel 1011 is connected to the exhaust port of the compressor 1, and the other end is connected to the refrigerant inlet of the water-cooled condenser 2 and the inlet of the second electronic expansion valve 5; a second flow channel 1012 provided on the refrigerant flow channel plate, one end of the first flow channel 1011 is connected to the refrigerant outlet of the water-cooled condenser 2, and the other end is connected to the inlet of the liquid storage tank 3; a third flow channel 1013 provided on the refrigerant flow channel plate, one end of the third flow channel 1013 is connected to the outlet of the liquid storage tank 3, and the other end is connected to the first electronic expansion valve 5. The inlet of the sub-expansion valve 4 is connected; a fourth flow channel 1014 is arranged on the refrigerant flow channel plate, one end of the fourth flow channel 1014 is connected to the outlet of the first electronic expansion valve 4, and the other end is connected to the inlet of the water-cooled evaporator 6; a fifth flow channel 1015 is arranged on the refrigerant flow channel plate, one end of the fifth flow channel 1015 is connected to the outlet of the water-cooled evaporator 6, and the other end is connected to the air inlet of the compressor 1; a sixth flow channel 1016 is arranged on the refrigerant flow channel plate, one end of the sixth flow channel 1016 is connected to the outlet of the second electronic expansion valve 5, and the other end is connected to the fifth flow channel 1015 to realize the mixing of the refrigerants and then pass into the air inlet of the compressor 1.
[0100] The compressor 1 bypasses the hot gas through the second electronic expansion valve 5, thereby increasing the suction pressure of the compressor 1 at an extremely low temperature, so that the heat pump system is not affected by the ambient temperature and performs heating.
[0101] Reference Figure 7The refrigerant flow channel plate in the embodiment of the present application includes a flow channel plate body 101 and a flow channel plate back plate 102 screwed to the flow channel plate body 101, wherein the aforementioned first flow channel 1011 to sixth flow channel 1016 are formed on the flow channel plate body 101 and are covered by the flow channel plate back plate 102. The compressor 1 is assembled on the flow channel plate back plate 102, and the remaining liquid storage tank 3, water-cooled condenser 2, water-cooled evaporator 6, first electronic expansion valve 4 and second electronic expansion valve 5 are installed on the flow channel plate body 101. Figure 9 The flow channel plate body 101 is provided with mounting seats for each PT sensor and mounting seats for each electronic expansion valve.
[0102] Reference Figure 9 In order to pre-fill the refrigerant, a refrigerant filling port 1017 is provided on the flow channel plate body 101 .
[0103] Reference Figure 7 The compressor 1 is fixed to the back plate 102 of the manifold by screws, thereby eliminating the refrigerant pipeline, reducing the volume and reducing the refrigerant charge. The back plate 102 of the manifold is provided with an air intake 1021 and an air discharge 1022 of the compressor 1.
[0104] Reference Figure 7 、 Figure 19 、 Figure 20 and Figure 21 Because compressor 1 experiences significant vibration during operation, a reliable fixing method is required to prevent vibration-induced fatigue failure and seal failure. Compressor 1 is sealed using three casing fixing screws 120 and three interface fixing screws 121. M8 or higher is recommended. The three casing fixing screws 120 are arranged in a triangle, located between the compressor's center of mass and the center of the triangle. This effectively increases the natural frequency of compressor 1 after fixing and prevents resonance. Due to the high exhaust pulsation and vibration on the exhaust side, two interface fixing screw mounting holes 122 are provided near the outlet of the exhaust flow channel 112. Two M8 interface fixing screws 121 are arranged horizontally to prevent leakage caused by uneven force on one side of the gasket. Since the inlet of compressor 1's intake flow channel 111 is located on the compressor housing and has two casing fixing screws 120 above and below, a single interface fixing screw mounting hole 122 is provided near the inlet of the intake flow channel 111. A single interface fixing screw 121 is sufficient for tightening and sealing.
[0105] Since the oil circulation rate of the system will affect the system's energy efficiency ratio (COP), that is, the oil needs to be retained in the compressor 1 and cannot participate in the heat exchange cycle. Usually, an oil separation device is set at the outlet of the compressor 1 to separate the refrigeration oil from the refrigerant through gravity and centrifugal force. Therefore, the outlet of the exhaust flow channel of the compressor 1 should be vertically upward, or within the range of ±45° vertically upward. Therefore, an exhaust adapter block 113 is provided in the embodiment of the present application, referring to Figure 17 and 18 The outlet of the exhaust flow channel 112 of the compressor 1 is connected to the exhaust port 1022 on the back plate 102 of the flow channel plate through the exhaust adapter block 113 and the exhaust port sealing structure 115, so as to achieve the oil separation effect while realizing the exhaust port and the intake port of the compressor 1 on the same plane (here, the exhaust port of the compressor 1 refers to the gas outlet after the conversion through the exhaust adapter block 113; the intake port of the compressor 1 refers to the inlet of the intake flow channel 111 of the compressor 1, and the inlet of the intake flow channel 111 of the compressor 1 is matched with the intake port 1022 on the back plate 102 of the flow channel plate through the intake port sealing structure 114), which is conducive to the direct assembly of the compressor 1 and the refrigerant flow channel plate.
[0106] Reference Figure 18 The PT sensor for detecting the exhaust temperature of the compressor 1 can be integrated on the exhaust adapter block 113 to ensure measurement accuracy.
[0107] The air inlet sealing structure 114 and the air outlet sealing structure 115 in the embodiment of the present application use a metal and rubber composite sealing ring, which can increase the compression rate and prevent the rubber part from being permanently deformed, thereby improving the sealing effect, thereby achieving simultaneous axial and radial sealing using a single metal and rubber composite sealing ring. The air inlet sealing structure 114 and the air outlet sealing structure 115 have the same specific structure, refer to Figure 22 The exhaust port sealing structure 115 includes a metal layer 1151 and a rubber layer 1152 vulcanized on the outer circle of the metal layer 1151 .
[0108] Since the air intake port 1021 and the air exhaust port 1022 on the manifold plate back plate 102 have unavoidable dimensional tolerances, the air intake port sealing structure 114 and the air exhaust port sealing structure 115 can realize the hard assembly of the compressor 1 on the manifold plate back plate 102 without leakage.
[0109] Reference Figure 19 The intake sealing groove 116 required for the intake port sealing structure 114 is set at the entrance of the intake air duct 111 of the compressor 1. The back plate 102 of the flow channel plate only needs to ensure the roughness and position of the interface to achieve sealing, which reduces the processing amount of the sealing end on the flow channel plate side; the entrance of the intake air duct on the compressor 1 extends toward the side of the back plate 102 of the flow channel plate to realize the guiding function of the sealing joint.
[0110] Reference Figure 20 The exhaust sealing groove 118 required for the exhaust port sealing structure 115 is set at the outlet of the exhaust flow channel 112 of the compressor 1. The flow channel plate back plate 102 only needs to ensure the roughness and position of the interface to achieve sealing, which reduces the processing amount of the sealing end on the flow channel plate side; a second protrusion structure 119 extends from the outlet of the exhaust flow channel 112 of the compressor 1 toward the side of the flow channel plate back plate 102 to realize the guiding function of the sealing joint.
[0111] Reference Figure 7 and Figure 8 In an embodiment of the present application, the refrigerant side integrated component also includes a first PT sensor PT1, a second PT sensor PT2 and a third PT sensor PT3 integrated on the refrigerant flow channel plate, the first PT sensor is connected to the fifth flow channel 1015, the second PT sensor is connected to the first flow channel 1011, and the third PT sensor is connected to the third flow channel 1013.
[0112] Reference Figure 8 The middle portion of the sixth flow channel 1016 is higher than the other end of the sixth flow channel 1016 where it connects to the fifth flow channel 1015. Since the sixth flow channel 1016, serving as a hot gas bypass flow channel, is only used in very low-temperature heat pumps and is used less frequently, the other end of the sixth flow channel 1016 where it connects to the fifth flow channel 1015 is raised by 10-20 mm to prevent refrigerant oil from remaining in the sixth flow channel 1016, which implements hot gas bypass, during conventional cooling and heating modes.
[0113] Reference Figure 8 The fifth flow channel 1015 is divided from its connection with the sixth flow channel 1016 into a first section connected to the outlet of the water-cooled evaporator 6 and a second section connected to the air inlet of the compressor 1. The second section is separated from the sixth flow channel 1016 by a partition wall. The refrigerant in the sixth flow channel 1016 and the refrigerant in the second section are thermally coupled via the partition wall. This partition wall allows the condensed high-pressure, medium-temperature refrigerant gas-liquid mixture at the outlet of the water-cooled condenser 2 to be thermally coupled with the superheated refrigerant gas at the outlet of the water-cooled evaporator 6. This increases the subcooling of the refrigerant entering the air inlet of the compressor 1 (approximately 5°C under maximum cooling conditions), thereby improving system performance.
[0114] The second section connected to the air inlet of the compressor 1 serves as a mixing section. The throttling flow channel (i.e., the sixth flow channel 1016) after the second electronic expansion valve 5 is connected to the first section connected to the outlet of the water-cooled evaporator 6. Mixing is performed in the second section with a length of more than 50 cm. The natural gas bypass flow channel and the low-pressure flow channel are arranged vertically. The turbulence formed by the vertical impact of the fluid is more conducive to the mixing of two refrigerants in different states, and thus returns to the air intake of the compressor 1, so that the high-temperature refrigerant in the gas state after throttling by the second electronic expansion valve under the hot gas bypass condition can be fully mixed with the low-pressure two-phase refrigerant, thereby preventing liquid hammer in the compressor 1.
[0115] In the embodiment of the present application, the refrigerant introduced into the refrigerant-side integrated assembly can be a medium such as R134a, 1234yf, R744, or R290. When the refrigerant is R290, which is a Class A3 flammable refrigerant, the biggest technical difficulty in solving the problem of using R290 refrigerant in passenger cars lies in safety. The refrigerant-side integrated assembly in the embodiment of the present application is completely isolated from the front-end module and HVAC assembly, completely eliminating the fuel risks caused by the R290 medium.

[0136] By switching the modes of the nine-way valve 12, the first three proportional valves and the second three-way valve 11, and by switching the four modes of the multi-way water valve, thermal management is achieved by switching the system modes in the secondary circuit R290 system, thereby realizing electric drive cooling, electric drive waste heat recovery, battery 21 cooling, battery 21 heating, passenger compartment cooling, passenger compartment heating, passenger compartment initialization and other functions.
[0137] In the embodiment of the present application, the water-cooled evaporator 6 is used to cool the battery 21 and the passenger compartment. Since the required temperatures for cooling the battery 21 and the passenger compartment are different, generally speaking, the battery 21 cooling temperature is about 17-25 degrees, and the required temperature for the passenger compartment is about 0-10 degrees, achieving the different temperature control of the two usually requires the use of two water-cooled evaporators 6, or two water pumps; however, this will result in an integrated module that is too large and difficult to arrange in the vehicle. Therefore, the system architecture optimization and product design used in the embodiment of the present application implement a mixed water design. The principle is that the water-cooled evaporator 6 prioritizes the temperature of components with low temperature requirements (usually the cold air core 16 in the passenger compartment), and then bypasses the battery outlet F and connects to the battery inlet E (the heated coolant at the battery outlet F is re-mixed with the lower temperature water at the battery inlet E, thereby achieving the temperature control of the battery inlet E). In summary, the battery 21 mixing function is achieved with a reduced number of parts and a compact structure.
[0138] Reference Figure 2 A one-way valve 13 is also integrated on the coolant flow channel plate, and the inlet and outlet of the one-way valve are connected to the thirteenth flow channel.
[0139] The heated coolant at the battery outlet F passes through the thirteenth flow channel serving as a bypass on the coolant flow channel plate and returns to the battery inlet E; the second three-way valve 11 adjusts the flow here to achieve different temperature and flow requirements for the battery 21 and the passenger compartment, and only one water-cooled evaporator 6 is used.
[0140] Reference Figure 2 and Figure 12The twenty-first flow channel and the twenty-fourth flow channel are connected to the high temperature area of the expansion kettle 14, and the twenty-fifth flow channel is connected to the low temperature area of the expansion kettle 14.
[0141] The twenty-first flow channel and the twenty-fourth flow channel form an exhaust circuit for the high-temperature zone of the expansion kettle 14. The gas-liquid mixed antifreeze liquid that bypasses into the expansion kettle 14 through the twenty-first flow channel is separated into gas and liquid due to gravity in the expansion kettle 14. The flow rate bypassing into the expansion kettle 14 can be adjusted through the twenty-fourth flow channel (approximately 30%±10% of the exhaust circuit flow rate).
[0142] The twenty-fifth flow channel is only used to replenish water to the coolant circuit that needs refrigeration, so as to prevent the high-temperature and low-temperature coolants from causing heat loss inside the expansion kettle 14.
[0143] Reference Figure 2 、 Figure 10 and Figure 11 The coolant-side integrated component also includes a first temperature sensor T1, a second temperature sensor T2, a third temperature sensor T3, a fourth temperature sensor T4, a fifth temperature sensor T5 and a sixth temperature sensor T6 integrated on the coolant flow channel plate, the first temperature sensor T1 is connected to the eleventh flow channel, the second temperature sensor T2 is connected to the twelfth flow channel, the third temperature sensor T3 is connected to the eighth flow channel, the fourth temperature sensor T4 is connected to the ninth flow channel, the fifth temperature sensor T5 is connected to the fourteenth flow channel, and the sixth temperature sensor T6 is connected to the nineteenth flow channel.
[0144] Reference Figure 16 In an embodiment of the present application, the refrigerant flow channel plate and the coolant flow channel plate are connected by a plurality of fixing screws.
[0145] In an embodiment of the present application, in order to realize the integration of the refrigerant integrated module and the coolant integrated module, it is necessary to arrange openings on the refrigerant flow channel plate so that the coolant side of the water-cooled evaporator 6 and the water-cooled condenser 2 face the coolant flow channel plate. The coolant side of the water-cooled evaporator 6 and the water-cooled condenser 2 passes through the refrigerant flow channel plate and matches the corresponding flow channel plate interface on the coolant flow channel plate to realize the circulation of the coolant in the water-cooled evaporator 6 and the water-cooled condenser 2.
