Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to an integrated water valve and thermal management system. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] With the rapid development of the new energy vehicle market, the requirements for thermal management systems are becoming increasingly stringent.

[0004] Currently, commonly used thermal management systems typically include integrated water valves. These integrated water valves are designed with multiple circulation loops and, based on the principles of vehicle thermal management, achieve switching between various operating conditions through complex water circuits. A typical integrated water valve consists of a valve core and a housing. The valve core is rotatably mounted within the housing, which has multiple valve ports along its axial direction. The valve core also has multiple sets of flow channel grooves along its axial direction. By rotating the valve core, different flow channel grooves on the valve core correspond to the valve ports, thus achieving the switching between different operating conditions.

[0005] The integrated water valve has a complex structure, and to achieve multiple mode switching, the more valve ports along the axial direction of the housing, the larger the axial dimension of the housing, and the larger the volume of the integrated water valve. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in the related art.

[0007] This utility model provides an integrated water valve, comprising:

[0008] An end plate having a connecting region and a non-connecting region, the connecting region having a plurality of valve ports, each valve port being configured to connect to a working module; and

[0009] A flow distribution assembly is disposed opposite to the end plate, and the end face of the flow distribution assembly facing the end plate has multiple docking areas, each docking area having multiple axial flow channel grooves, each flow channel groove being able to connect at least two valve ports;

[0010] A drive assembly is provided, wherein the flow distribution assembly is disposed at the output end of the drive assembly, and the drive assembly is capable of driving the flow distribution assembly to rotate, so that the different docking areas of the flow distribution assembly are arranged opposite to the connecting areas, and the interconnected valve ports form a water passage through the flow channel groove.

[0011] The integrated water valve distribution component and end plate structure are arranged opposite each other. By rotating the distribution component, different docking areas and connecting areas of the distribution component can be aligned to achieve state switching. The end plate with valve port is thin and close to the distribution component, and the structure is relatively simple. It can reduce the overall volume of the integrated water valve. Switching can be achieved by controlling the rotation angle, which reduces the complexity of control.

[0012] In some embodiments, the number of valve ports is thirteen. This large number of valve ports indicates a high degree of water circuit integration in the integrated water valve section.

[0013] In some embodiments, the end plate includes:

[0014] The subject; and

[0015] A boss is provided on the valve port, and the boss is provided on the end face of the body opposite to the flow distribution assembly.

[0016] The integrated water valve with this end plate is suitable for use in scenarios with integrated water circuit modules. The boss structure facilitates the installation and positioning of the integrated water valve. The integrated water valve can be directly snapped on and fixed with bolts, which is beneficial for the integration of the thermal management system.

[0017] In some embodiments, the end plate is a flat plate structure, which is simple in structure and can be applied to other working conditions without angle requirements.

[0018] In some embodiments, there are eight docking areas along a first direction, and the eight docking areas are respectively a first area, a second area, a third area, a fourth area, a fifth area, a sixth area, a seventh area, and an eighth area. When the integrated water valve is in a first state, the first area corresponds to the connecting area.

[0019] When the integrated water valve is in the second state, the flow distribution assembly rotates 45° in the first direction in the first state, so that the second area corresponds to the communication area;

[0020] When the integrated water valve is in the third state, the flow distribution assembly rotates 90° in the first direction in the first state, so that the third area corresponds to the communication area;

[0021] When the integrated water valve is in the fourth state, the flow distribution assembly rotates 135° in the first direction in the first state, so that the fourth area corresponds to the connecting area;

[0022] When the integrated water valve is in the fifth state, the flow distribution assembly rotates 180° in the first direction in the first state, so that the fifth zone corresponds to the communication zone;

[0023] When the integrated water valve is in the sixth state, the flow distribution assembly rotates 225° in the first direction in the first state, so that the sixth zone corresponds to the communication zone;

[0024] When the integrated water valve is in the seventh state, the flow distribution assembly rotates 270° in the first direction in the first state, so that the seventh zone corresponds to the communication zone;

[0025] When the integrated water valve is in the eighth state, the flow distribution assembly rotates 315° in the first direction in the first state, so that the eighth zone corresponds to the connecting zone.

[0026] The integrated water valve's state switching is achieved simply by driving the distribution component to rotate at a fixed angle using the drive component. Operation is simple, and the drive component control is relatively straightforward, as it can be implemented using a stepper motor. This reduces control complexity, ensures control precision and accuracy, and helps lower costs.

[0027] In some embodiments, the drive component includes a stator, and the current distribution component includes:

[0028] A distributor plate, wherein the docking area is disposed on the end face of the distributor plate facing the end plate; and

[0029] A drive shaft, one end of which is connected to the distributor plate; and

[0030] A bearing, which is sleeved on the drive shaft and located between the drive shaft and the stator.

[0031] The distributor plate and drive shaft are integrated into one structure, which is simple and easy to assemble. The bearing helps to reduce the friction between the drive shaft and the stator when the drive shaft rotates, thereby improving the service life of the drive shaft and the stator.

[0032] In some embodiments, it also includes:

[0033] The housing, the flow distribution assembly and the drive assembly are located in the housing, and the end plate is disposed on the end face of the housing and connected to the housing.

[0034] This integrated water valve facilitates modularity and sealing, making it easy to assemble, replace, and maintain.

[0035] A thermal management system, comprising:

[0036] The integrated water valve as described above;

[0037] The system comprises a first heat exchange module, a first electric drive module, a battery cycle module, a second heat exchange module, a cockpit heating module, and a second electric drive module.

[0038] The thermal management system switches its operating mode by controlling the status of the integrated water valve.

[0039] Compared with traditional thermal management systems, this thermal management system has fewer components, a simpler structure, and reduced control complexity. It is also more conducive to modular and platform-based porting of the thermal management system, facilitating further integrated development.

[0040] In some embodiments, in the first operating mode, the first heat exchange module is connected to the first electric drive module to cool the cockpit;

[0041] In the second working mode, the first heat exchange module is connected to the first electric drive module, and the battery circulation module is connected to the second heat exchange module, which is used for cockpit cooling and battery cooling.

[0042] In the third working mode, the cockpit heating module is connected in series with the first heat exchange module, and the first electric drive module is connected with the second heat exchange module, which is used for cockpit heating.

[0043] In the fourth operating mode, the first heat exchange module is connected to the battery circulation module, and the first electric drive module is connected to the second heat exchange module, which is for battery heating.

[0044] In the fifth working mode, the first heat exchange module is connected to the battery circulation module, and the first heat exchange module is connected in parallel with the cockpit heating module. The second electric drive module is connected to the second heat exchange module to heat the battery and the cockpit.

[0045] In the sixth operating mode, the first heat exchange module is connected to the battery circulation module, and the first heat exchange module is connected in parallel with the cockpit heating module. The first electric drive module is connected to the second heat exchange module to heat the battery and the cockpit.

[0046] In the seventh operating mode, the first electric drive module is connected to the first heat exchange module, and the first heat exchange module is connected in parallel with the cockpit heating module. The battery circulation module is connected to the second heat exchange module, thereby achieving cockpit heating and dehumidification and electric drive module heat dissipation; and

[0047] In the eighth operating mode, the first electric drive module and the second heat exchange module are connected to dissipate heat from the electric drive module.

[0048] This thermal management system integrates different docking areas of water valves to form loops with different modules of the thermal management system, enabling different functions. The adjustment method is simple and the modes are diversified. Compared with traditional thermal management systems, it reduces the number of components in the architecture, and the structure of the thermal management system is relatively simple, reducing the complexity of thermal management system control. It is conducive to the modularization and platformization of the thermal management system and further integrated development.

[0049] In some embodiments, it also includes:

[0050] When the thermal management system is in the fourth working mode, the battery circulation module is connected in series with the first three-way valve and then connected to the first heat exchange module through the integrated water valve. The three-way valve has a first interface, a second interface, and a third interface. The first interface is connected to the downstream outlet of the battery circulation module, and the second interface and the third interface are connected to different valve ports of the integrated water valve to regulate the flow rate through the battery circulation module.

[0051] The first three-way valve can adjust the speed of the first and second water pumps to ensure a reasonable distribution of flow between them, thus ensuring the rationality of flow and related heat exchange. This prevents the battery from overheating during the heating process of the water source heat pump and improves the safety of the thermal management system.

[0052] In some embodiments, it also includes:

[0053] The second three-way valve has a fourth port, a fifth port, and a sixth port. When the thermal management system is in the fifth working mode, the fourth port is connected to the water inlet of the first heat exchange module, the fifth port is connected to the water outlet of the cockpit heating module, and the sixth port is connected to one valve port of the integrated water valve to form a parallel circuit between the first heat exchange module and the cockpit heating module.

[0054] This second three-way valve simplifies the connection method of parallel circuits and the stability of water circuit connectivity. Attached Figure Description

[0080] Example 1

[0081] like Figure 1 and Figure 2 As shown, this embodiment provides an integrated water valve 1000, which includes an end plate 100, a flow distribution assembly 200, and a drive assembly 300. The end plate 100 has a connecting area 110 and a non-connecting area 120110. The connecting area 110 has multiple valve ports 111, each valve port 111 being configured to connect to a working module. The flow distribution assembly 200 is disposed opposite to the end plate 100, and the end face of the flow distribution assembly 200 facing the end plate 100 has multiple mating areas 210. Each mating area 210 has multiple axial flow channel grooves 211, each flow channel groove 211 capable of connecting at least two valve ports 111. The flow distribution assembly 200 is disposed at the output end of the drive assembly 300, which can drive the flow distribution assembly 200 to rotate, causing the different mating areas 210 of the flow distribution assembly 200 to be disposed opposite to the connecting area 110, and forming a water path through the interconnected valve ports 111 via the flow channel grooves 211. The integrated water valve 1000 has a flow distribution component 200 structure and an end plate 100 structure arranged opposite to each other. By rotating the flow distribution component 200, different docking areas 210 of the flow distribution component 200 can be aligned with the connecting area 110 to achieve state switching. The end plate 100 with valve port 111 has a small thickness and is close to the flow distribution component 200, and the structure is relatively simple. This can reduce the overall volume of the integrated water valve 1000. Switching can be achieved by controlling the rotation angle, which reduces the complexity of control.

[0082] Among them, the flow channel 211 is a blind hole to prevent water leakage.

[0083] Specifically, the end plate 100 can be a plate with a circular outline, which helps to reduce the axial dimension of the integrated water valve 1000 along the end plate 100 and reduce its volume. The connecting area 110 and the docking area 210 are fan-shaped regions, and the central angle of the connecting area 110 is the same as the central angle of the docking area 210, so that the connecting area 110 and the docking area 210 are set in a corresponding manner to ensure the correspondence between the connecting area 110 and the docking area 210.

[0084] Furthermore, such as Figure 3 and Figure 4 There are thirteen valve ports 111, which is a relatively large number, indicating a high degree of water circuit integration in the integrated water valve 1000. The thirteen valve ports 111 are arranged in a fan-shaped array in the fan-shaped connecting area 110, which improves the aesthetics of the end plate 100. Specifically, according to the size of the fan radius, the outermost valve ports 111 are numbered 12, 11, 8, 10, and 9; the second layer is numbered 13, 7, 6, and 4; the third layer is numbered 1, 5, and 3; and the innermost layer is numbered 2. These thirteen valve ports 111 together form the fan-shaped connecting area 110 shown in the figure.

[0085] The non-connected area 120 is a planar structure and does not have a valve port 111.

[0086] In use, the water flow enters the flow channel 211 of the distribution component 200 through the valve port 111, thereby achieving water circuit connection.

[0087] In some embodiments, see Figure 3 The end plate 100 includes a body 130 and a boss 140. A valve port 111 is disposed on the boss 140, which is located on the end face of the body 130 facing away from the distribution assembly 200. The boss 140 has a fan-shaped structure with rounded corners near its center to improve safety. The integrated water valve 1000 with this end plate 100 is suitable for use with integrated water circuit modules. The structure of the boss 140 facilitates the installation and positioning of the integrated water valve 1000, allowing it to be directly snapped in and fixed with bolts, which is beneficial for the integration of the thermal management system. Specifically, the boss 140 is designed to accommodate installation angle requirements when mounted on an integrated module, such as situations where the integrated water valve 1000 can only achieve water flow at a certain angle.

[0088] In other embodiments, please refer to Figure 4 The end plate 100 has only a planar structure. The end plate 100 has a simple structure and can be applied to other working conditions without angle requirements.

[0089] like Figure 5As shown, there are eight docking areas 210. Along the first direction, the eight docking areas 210 are designated as area 1 212, area 213, area 3 214, area 4 215, area 5 216, area 6 217, area 7 218, and area 8 219. It can be seen that if the eight docking areas 210 are evenly distributed, the central angle corresponding to each docking area 210 is 45°.

[0090] Specifically: when the integrated water valve 1000 is in the first state, the first zone 212 corresponds to the connecting zone 110; when the integrated water valve 1000 is in the second state, the flow distribution assembly 200 rotates 45° in the first direction in the first state, so that the second zone 213 corresponds to the connecting zone 110; when the integrated water valve 1000 is in the third state, the flow distribution assembly 200 rotates 90° in the first direction in the first state, so that the third zone 214 corresponds to the connecting zone 110; when the integrated water valve 1000 is in the fourth state, the flow distribution assembly 200 rotates 135° in the first direction in the first state, so that the fourth zone 215 corresponds to the connecting zone 110; when the integrated water valve 1000 is in the fifth state... In the first state, the flow distribution assembly 200 rotates 180° along the first direction, so that the fifth zone 216 corresponds to the connecting zone 110; in the sixth state, the integrated water valve 1000 rotates 225° along the first direction, so that the sixth zone 217 corresponds to the connecting zone 110; in the seventh state, the integrated water valve 1000 rotates 270° along the first direction, so that the seventh zone 218 corresponds to the connecting zone 110; in the eighth state, the integrated water valve 1000 rotates 315° along the first direction, so that the eighth zone 219 corresponds to the connecting zone 110.

[0091] The state switching of the integrated water valve 1000 can be achieved simply by driving the distribution component 200 to rotate at a fixed angle through the drive component 300. The operation is simple, and the control of the drive component 300 is relatively simple. It can be achieved by stepper motor, which reduces the complexity of control, ensures the accuracy and precision of control, and helps to reduce costs.

[0092] Further, please see Figure 6 and Figure 7 The flow distribution assembly 200 includes a flow distribution plate 220 and a drive shaft 230. A mating area 210 is located on the end face of the flow distribution plate 220 facing the end plate 100. One end of the drive shaft 230 is connected to the flow distribution plate 220. The structure of the flow distribution plate 220 is simpler than that of the axial flow channel groove 211, resulting in a more stable matching mode for the integrated water valve 1000 under different states. The flow distribution plate 220 and the drive shaft 230 are an integral structure, which is simple and easy to assemble.

[0093] Zones 212, 213, 214, 215, 216, 217, 218, and 219 constitute eight regions of the distribution plate 220. Flow channel grooves 211 are formed in these eight regions. Since each docking region 210 can perform different functions when corresponding to the connecting region 110, the structure and number of flow channel grooves 211 formed in each docking region 210 are different. Specifically, the flow channel groove 211 is formed by a recess in the end facing the connecting region 110 towards the drive shaft 230.

[0094] The opening and closing of the water passage at valve port 111 corresponds to the structure of the flow channel groove 211 inside the distribution plate 220. The structure of the flow channel groove 211 enables communication between different valve ports 111.

[0095] The two ends of the flow channel 211 are designed with rounded corners to reduce water flow resistance.

[0096] To ensure the sealing between the distribution plate 220 and the end plate 100, a sealing element can also be installed between the end plate 100 and the distribution plate 220 to prevent water from overflowing.

[0097] Furthermore, the drive assembly 300 includes a stator, and the bearing 240 is located between the drive shaft 230 and the stator to reduce friction between the drive shaft 230 and the stator when the drive shaft 230 rotates, thereby improving the service life of the drive shaft 230 and the stator.

[0098] The drive shaft 230 has a bearing groove 231, which is located near the distribution plate 220. The bearing 240 is sleeved on the drive shaft 230 and located in the bearing groove 231, thereby avoiding rotational friction of the drive shaft 230 and improving the service life of the drive shaft 230.

[0099] Meanwhile, the bearing 240 supports the drive shaft 230, which helps improve the stability of the drive shaft 230 along its axis during rotation, thereby improving the stability and accuracy of the integrated water valve 1000's state switching. Specifically, the inner ring of the bearing 240 contacts the drive shaft 230 with an interference fit, the outer ring of the bearing 240 has a clearance fit with the inner wall of the drive assembly 300, and the outer ring of the bearing 240 is relatively fixed to the stator, thus enabling the inner and outer rings of the bearing 240 to rotate relative to each other, thereby allowing the drive assembly 300 to drive the drive shaft 230 to rotate.

[0100] As an alternative, the drive assembly 300 also includes a motor winding wound on the stator, which is used to drive the rotation of the drive shaft 230.

[0101] In some embodiments, the integrated water valve 1000 further includes a housing 400, a flow distribution assembly 200 and a drive assembly 300 located within the housing 400, and an end plate 100 disposed on the end face of the housing 400 and connected to the housing 400, thereby achieving modularity and sealing of the integrated water valve 1000, facilitating its assembly, replacement and maintenance. This integrated water valve has a simple external structure, making it easy to install on thermal management integrated modules and improving the integration level of the thermal management system.

[0102] Specifically, the housing 400 has a cylindrical structure, the drive assembly 300 is disposed within the housing 400, the drive shaft 230 of the distribution assembly 200 passes through the stator of the drive assembly 300, the distribution plate 220 is connected to the drive shaft 230 and located within the housing 400, and the end plate 100 is disposed on the end face of the housing 400 and is sealed to the distribution plate 220. This integrated water valve 1000 structure enables the drive assembly 300 to drive the drive shaft 230 to rotate, thereby rotating the distribution plate 220 and aligning different mating areas 210 of the distribution plate 220 with the connecting areas 110 of the end plate 100, achieving state switching. The dimensions of the integrated water valve 1000 along its axis only include the length of the drive assembly 300, the thickness of the distribution plate 220, and the thickness of the end plate 100, which helps to reduce volume.

[0103] Furthermore, the end plate 100 and the housing 400 are connected by eight sets of bolts to ensure the stability of the connection and the sealing of the water passage.

[0104] In summary, the integrated water valve 1000 has a large number of valve ports 111, and the water circuit integration in the integrated water valve 1000 is relatively high. If the application scenario is a thermal management integrated module, the integrated water valve 1000 can replace multiple multi-way valves on the traditional integrated module, which can greatly improve the water circuit integration and optimize or even simplify the structural design of the integrated module.

[0105] Compared with other multi-way valves, the integrated water valve 1000 has a valve port 111 and a flow channel groove 211 on the axial end face, and the valve port 111 and the flow channel groove 211 correspond one-to-one and are close to each other. This can reduce the overall size of the integrated water valve 1000, and at the same time eliminate the problem of the motor and controller of the integrated water valve 1000 being installed on the end face of the housing 400, which would result in a long overall layout and large space occupation.

[0106] Example 2

[0107] This embodiment provides a thermal management system, which includes the integrated water valve 1000 of Embodiment 1.

[0108] The thermal management system also includes a first heat exchange module 2000, a first electric drive module 3000, a battery circulation module 4000, a second heat exchange module 5000, a cockpit heating module 6000, and a second electric drive module. The thermal management system switches operating modes by adjusting the state of the integrated water valve 1000. The thermal management system switches thermal management modes by adjusting the docking area 210 of the switching end plate 100.

[0109] Compared with traditional thermal management systems, this thermal management system has fewer components, a simpler structure, and reduced control complexity. It is also more conducive to modular and platform-based porting of the thermal management system, facilitating further integrated development.

[0110] The first heat exchange module 2000 includes a first water pump 2001, a liquid-cooled condenser 2002, and an electric heater 2003. The first electric drive module 3000 includes a first heat exchanger 3001 and an electric drive module 3002. The first heat exchanger 3001 can be a low-temperature radiator. The electric drive system includes, but is not limited to, a motor and a motor controller. The battery circulation module 4000 includes a second water pump 4001 and a battery 4002. The second heat exchange module 5000 includes a third water pump 5001 and a second heat exchanger 5002. Optionally, the second heat exchanger 5002 can be an evaporator. The cockpit heating module 6000 includes a water heater. The second electric drive module includes a first heat exchanger 3001, which can be a low-temperature radiator.

[0111] The thermal management system has eight operating modes for the eight docking zones 210 of the distribution plate 220. The eight operating modes are described in detail below.

[0112] like Figure 8 As shown, in the first working mode, the first heat exchange module 2000 is connected to the first electric drive module 3000 to cool the cockpit.

[0113] In this first working mode, the sequence number and water flow direction of the internal flow channel connecting valve port 111 of the integrated water valve 1000 are 5→1, 11→13→8→7, and the corresponding flow channel groove 211 structure design of the first area 212 of the distribution plate is as follows: Figure 5 As shown, the first area 212 has two sets of flow channel grooves 211, one large and one small, which correspond to the corresponding valve ports 111. The external circuit of the integrated water valve 1000 is connected between the first heat exchange module 2000 and the first electric drive module 3000, and forms a closed loop through the valve ports 111 numbered 1, 11, 7, and 5.

[0114] In the first operating mode of the thermal management system, the water flows through valve port 111 (number 1) to the first water pump 2001, liquid-cooled condenser 2002, and electric heater 2003 of the first heat exchange module 2000, and then to valve port 111 (number 11). It then flows sequentially through valve ports 13, 8, and 7 via the flow channel 211 of the distribution plate. From valve port 7 (number 7), it connects to the first heat exchanger 3001 and the electric drive module 3002, then flows to valve port 111 (number 5), and finally connects to valve port 111 (number 1) via the flow channel 211, thus forming a complete loop. This loop is an electrically driven water circuit, in which the liquid-cooled condenser 2002 is connected to the air conditioning circuit, enabling the vehicle's cockpit to be cooled.

[0115] Please see Figure 9 In the second working mode, the first heat exchange module 2000 is connected to the first electric drive module 3000, and the battery circulation module 4000 is connected to the second heat exchange module 5000, for cooling the cockpit and the battery 4002.

[0116] In this operating mode, the sequence numbers and water flow directions of the internal flow channels connecting valve ports 111 of the integrated water valve 1000's distribution plate are 5→1, 11→13→8→7, 2→3, and 6→10. The structural design of the flow channel groove 211 corresponding to the second zone 213 of the distribution plate is as follows... Figure 5 As shown, the second region 213 has four sets of flow channel grooves 211 of different shapes, which correspond to the corresponding valve ports 111.

[0117] The integrated water valve 1000 of the thermal management system has two external loops. One loop connects the first heat exchange module 2000 and the first electric drive module 3000 through valve port 111, forming a closed loop through valve ports 111 numbered 1, 11, 7, and 5. The other loop connects the battery circulation module 4000 and the second heat exchange module 5000, forming a closed loop through valve ports 111 numbered 2, 3, 6, and 10.

[0118] In the thermal management system, under the second operating mode, the water flow direction is through valve port 111 (number 1) to the first water pump 2001, liquid-cooled condenser 2002, and electric heater 2003 of the first heat exchange module 2000, and then to valve port 111 (number 11). Then, under the connection of the flow channel groove 211 of the distribution plate, the water flows through valve ports 111 (numbers 13, 8, and 7) in sequence. Then, it connects to the first heat exchanger 3001 and the electric drive module 3002 from valve port 111 (number 7), and then flows to valve port 111 (number 5). Finally, it connects to valve port 111 (number 1) through the flow channel groove 211, thus forming a complete loop, which is an electric drive water circuit. Another loop is as follows: valve port 111 with serial number 3 is connected to the water pump and the second heat exchanger 5002 of the second heat exchange module 5000, and then flows to valve port 111 with serial number 6, and then flows through the flow channel 211 to valve port 111 with serial number 10. Valve port 111 with serial number 10 is connected in sequence to the second water pump 4001 and the battery 4002 of the battery circulation module 4000, and is connected to valve port 111 with serial number 2, and then flows through the flow channel 211 to valve port 111 with serial number 3. This loop is the water circuit of battery 4002.

[0119] The two circuits exchange heat between the refrigerant side and the water side of the liquid-cooled condenser 2002 and the evaporator, enabling the vehicle thermal management system battery 4002 to cool and the dual-evaporation cooling system to function.

[0120] Please see Figure 10 In the third working mode, the cockpit heating module 6000 is connected in series with the first heat exchange module 2000, and the first electric drive module 3000 and the second heat exchange module 5000 are connected to provide heating for the cockpit.

[0121] In this operating mode, the sequence numbers and water flow directions of the internal flow channels connecting valve ports 111 of the integrated water valve 1000 are 5→3, 6→7, and 11→12. The structural design of the flow channel groove 211 corresponding to the third zone 214 of the distribution plate is as follows... Figure 5 As shown, the third region 214 has three sets of flow channel grooves 211 of different shapes, which correspond to the corresponding valve ports 111.

[0122] The integrated water valve 1000 of the thermal management system has two external circuits. One circuit is a closed loop formed by connecting the cockpit heating module 6000 and the first heat exchange module 2000 in series and connecting them with serial numbers 11 and 12. The other circuit is a closed loop formed by connecting the first electric drive module 3000 and the second heat exchange module 5000 and connecting them with serial numbers 3, 6, 7, and 5.

[0123] In the thermal management system, under the third operating mode, the water flow direction is as follows: valve port 111 (number 12) is sequentially connected to the water heater, the first water pump 2001, the liquid-cooled condenser 2002, and the electric heater 2003, forming a loop to valve port 111 (number 11). This loop is the water circuit for the vehicle's driver's compartment. Valve port 111 (number 3) is connected to the third water pump 5001 and the second heat exchanger 5002, forming a loop to valve port 111 (number 6). Then, inside the distribution plate 220, valve port 111 (number 6) connects to valve port 111 (number 7). Valve port 111 (number 7) is connected to the first heat exchanger 3001 and the electric drive module 3002, forming a loop to valve port 111 (number 5). Finally, it connects to valve port 111 (number 3) via the distribution plate 220, forming a closed-loop circuit. This circuit is the electric drive circuit. In this mode, the two circuits exchange heat between the refrigerant side and the water side through the liquid-cooled condenser 2002 and the evaporator, which can transfer the heat of the electric drive circuit to the cockpit water circuit and realize the cockpit water source heat pump heating function.

[0124] Please see Figure 11 In the fourth working mode, the first heat exchange module 2000 is connected to the battery circulation module 4000, and the first electric drive module 3000 is connected to the second heat exchange module 5000 to heat the battery 4002.

[0125] In this operating mode, the sequence numbers and water flow directions of the internal flow channels connecting valve ports 111 of the integrated water valve 1000 are 5→3, 6→7, 2→1, 11→13→8→10. The design structure of the flow channel groove 211 corresponding to the fourth zone 215 of the distribution plate is as follows... Figure 5 As shown, the fourth zone 215 has four sets of flow channel grooves 211 of different shapes, each corresponding to a valve port 111.

[0126] The integrated water valve 1000 of the thermal management system has two outflow channels. One channel connects the first heat exchange module 2000 and the battery circulation module 4000, and forms a closed loop through valve ports 111 numbered 2, 1, 11, 13, 8, and 10. The other channel connects the first electric drive module 3000 and the second heat exchange module 5000, and forms a closed loop through valve ports numbered 3, 6, 7, and 5.

[0127] In the thermal management system, under the fourth operating mode, the water flow direction is as follows: valve port 111 with serial number 10 connects to the second water pump 4001 and battery 4002 to valve port 111 with serial number 2. Then, valve port 111 with serial number 2 connects to valve port 111 with serial number 1 through the flow channel groove 211 of the distribution plate 220. Valve port 111 with serial number 1 connects to the first water pump 2001, liquid cooling condenser 2002 and electric heater 2003 to valve port 111 with serial number 11. Valve port 111 with serial number 11 flows through valve ports 111 with serial numbers 13, 8 and 10 in the flow channel groove 211 to form a loop. This loop is the water path of battery 4002. Another loop is as follows: valve port 111 (serial number 3) connects to the third water pump 5001 and the second heat exchanger 5002, then to valve port 111 (serial number 6). Inside the distribution plate 220, valve port 111 (serial number 6) connects to valve port 111 (serial number 7). Valve port 111 (serial number 7) connects to the first heat exchanger 3001 and the electric drive module 3002, then to valve port 111 (serial number 5), and finally connects to valve port 111 (serial number 3) via the distribution plate 220, forming a closed-loop loop. This loop is the electric drive loop. In this mode, the two loops exchange heat between the refrigerant side and the water side of the liquid-cooled condenser 2002 and evaporator, enabling the transfer of heat from the electric drive loop to the water circuit of the battery 4002, thus realizing the water source heat pump heating function of the battery 4002.

[0128] The thermal management system also includes a first three-way valve 8000. When the thermal management system is in the fourth operating mode, the battery circulation module 4000 is connected in series with the first three-way valve 8000 and then connected to the first heat exchange module 2000 through an integrated water valve 1000. The three-way valve has an 8002, a second port 8002, and a third port 8003. The first port 8001 is connected to the downstream outlet of the battery circulation module 4000, and the second port 8002 and the third port 8003 are connected to different valve ports 111 of the integrated water valve 1000. Specifically, the second port 8002 is connected to the port 2 of the integrated water valve 1000. The valve port 111 is connected, and the third interface 8003 is connected to the valve port 111 with serial number 9. Through the flow channel groove 211, the valve port 111 with serial number 9 is connected to the valve port 111 with serial number 10 to adjust the flow rate through the battery circulation module 4000. By adjusting the speed of the first water pump 2001 and the second water pump 4001, the flow rate is reasonably distributed between the first water pump 2001 and the second water pump 4001, ensuring the rationality of the flow rate and related heat exchange, preventing the battery 4002 from overheating and causing safety problems during the heating process of the water source heat pump, and improving the safety of the thermal management system.

[0129] Please see Figure 12In the fifth working mode, the first heat exchange module 2000 is connected to the battery circulation module 4000, and at the same time, the first heat exchange module 2000 is connected in parallel with the cockpit heating module 6000. The second electric drive module is connected to the second heat exchange module 5000 to heat the battery 4002 and the cockpit.

[0130] In this fifth operating mode, the sequence numbers and water flow directions of the internal flow channels connecting valve ports 111 of the distribution plate 220 of the integrated water valve 1000 are 4→3, 6→5, 2→1, 11→13→8→10, and 11→12 in parallel. The structural design of the flow channel groove 211 corresponding to the fifth zone 216 of the distribution plate 220 is as follows... Figure 5 As shown, the fifth zone 216 has four sets of flow channel grooves 211 of different shapes, each corresponding to a valve port 111.

[0131] The integrated water valve 1000 has two external circuits. One circuit connects the first heat exchange module 2000 and the battery circulation module 4000, forming a closed loop through valve ports 111 numbered 11, 13, 8, 10, 2, and 1. Simultaneously, the first heat exchange module 2000 and the cockpit heating module 6000 are connected in parallel, forming a parallel loop between port 12 and one end of the first heat exchange module 2000's water inlet. The other circuit connects the second electric drive module and the second heat exchange module 5000, forming a loop through valve ports 111 numbered 4, 3, 6, and 7.

[0132] In the thermal management system, under the fifth working mode, the water flow direction is as follows: valve port 111 with serial number 10 connects to the second water pump 4001 and battery 4002 to valve port 111 with serial number 2. Then, valve port 111 with serial number 2 connects to valve port 111 with serial number 1 through the flow channel groove 211 of the distribution plate 220. Valve port 111 with serial number 1 connects to the first water pump 2001, liquid cooling condenser 2002 and electric heater 2003 to valve port 111 with serial number 11. Valve port 111 with serial number 11 flows through valve ports 111 with serial numbers 13, 8 and 10 in the flow channel groove 211 to form a loop. This loop is the water path of battery 4002. Meanwhile, valve port 111 with serial number 11 is also connected to valve port 111 with serial number 12. Valve port 111 with serial number 12 is connected to the water heater of the cockpit heating module 6000, and then connected to the water inlet of the first water pump 2001 to form a parallel water circuit.

[0133] The thermal management system also includes a first three-way valve 8000. When the thermal management system is in the fifth working mode, the battery circulation module 4000 is connected in series with the first three-way valve 8000 and then connected to the first heat exchange module 2000 through an integrated water valve 1000. The three-way valve has a first port 8001, a second port 8002, and a third port 8003. The first port 8001 is connected to the downstream outlet of the battery circulation module 4000. The second port 8002 and the third port 8003 are connected to different valve ports 111 of the integrated water valve 1000. Specifically, the second port 8002 is connected to the port 111 of the integrated water valve 1000. The valve port 111 of 2 is connected, and the third interface 8003 is connected to the valve port 111 of serial number 9. Through the flow channel groove 211, the valve port 111 of serial number 9 is connected to the valve port 111 of serial number 10 to regulate the flow rate through the battery circulation module 4000. By adjusting the speed of the first water pump 2001 and the second water pump 4001, the flow rate is reasonably distributed between the first water pump 2001 and the second water pump 4001, ensuring the rationality of the flow rate and related heat exchange, preventing the battery 4002 from overheating and causing safety problems during the heating process of the water source heat pump, and improving the safety of the thermal management system.

[0134] Another loop is as follows: valve port 111 with serial number 3 is connected to the third water pump 5001 and the second heat exchanger 5002 to valve port 111 with serial number 6. Then, inside the distribution plate 220, valve port 111 with serial number 6 is connected to valve port 111 with serial number 7. Valve port 111 with serial number 7 is connected to the first heat exchanger 3001 to valve port 111 with serial number 4. Then, it is connected to valve port 111 with serial number 3 through the distribution plate 220 to form a closed loop. This loop is an electrically driven loop.

[0135] In this mode, the heat exchange between the refrigerant side and the water side of the two circuits through the liquid-cooled condenser 2002 and the evaporator can transfer the heat from the air side to the battery 4002 and the cockpit water circuit, provided that it is in a relatively low temperature environment. In extremely low temperature environments, the heat absorbed by this air source mode is limited.

[0136] As an optional solution, the thermal management system also includes a second three-way valve 9000. The second three-way valve 9000 has a fourth port 9001, a fifth port 9002, and a sixth port 9003. When the thermal management system is in its fifth operating mode, the fourth port 9001 is connected to the inlet of the first heat exchange module 2000, the fifth port 9002 is connected to the outlet of the cockpit heating module 6000, and the sixth port 9003 is connected to one valve port 111 of the integrated water valve 1000, thus forming a parallel circuit between the first heat exchange module 2000 and the cockpit heating module 6000. This second three-way valve 9000 simplifies the connection method of the parallel circuit and improves the stability of the water circuit connection.

[0137] As an optional solution, the second electric drive module and the first electric drive module 3000 share the first heat exchanger 3001. A third three-way valve 10000 is also provided between the first heat exchanger 3001 and the electric drive module 3002. The third three-way valve 10000 has a seventh port 10001, an eighth port 10002, and a ninth port 10003. The seventh port 10001 is connected to the first heat exchanger 3001, the eighth port 10002 is connected to the electric drive module 3002, and the ninth port 10003 is connected to valve port 111 (number 4). With this connection method, when the thermal management system is in the fifth operating mode, it can be connected to valve port 111 (number 4) via the ninth port 10003 of the third three-way valve 10000. This solution simplifies the structure of the thermal management system.

[0138] Please see Figure 13 In the sixth working mode, the first heat exchange module 2000 is connected to the battery circulation module 4000, and at the same time, the first heat exchange module 2000 is connected in parallel with the cockpit heating module 6000. The first electric drive module 3000 is connected to the second heat exchange module 5000 to heat the battery 4002 and the cockpit.

[0139] The difference between the sixth working mode and the fifth working mode is only that valve port 111 (number 7) connects the first heat exchanger 3001 and the electric drive module 3002 of the first electric drive module 3000 to valve port 111 (number 5). The rest of the structure is the same as the fifth working mode.

[0140] In this sixth operating mode, the sequence numbers and water flow directions of the internal flow channels connecting valve ports 111 of the distribution plate 220 of the integrated water valve 1000 are 5→3, 6→7, 2→1, 11→13→8→10, and 11→12 in parallel. The structural design of the flow channel groove 211 corresponding to the first zone 212 of the distribution plate 220 is as follows... Figure 5 As shown, the sixth zone 217 has four sets of flow channel grooves 211 of different shapes, each corresponding to a valve port 111.

[0141] The integrated water valve 1000 has two external circuits. One circuit connects the first heat exchange module 2000 and the battery circulation module 4000, forming a closed loop through valve ports 111 numbered 11, 13, 8, 10, 2, and 1. Simultaneously, the first heat exchange module 2000 and the cockpit heating module 6000 are connected in parallel, forming a parallel loop between port 12 and one end of the first heat exchange module 2000's water inlet. The other circuit connects the second electric drive module and the second heat exchange module 5000, forming a loop through valve ports 111 numbered 5, 3, 6, and 7.

[0142] In the thermal management system, under the sixth operating mode, the water flow direction is as follows: valve port 111 with serial number 10 connects to the second water pump 4001 and battery 4002 to valve port 111 with serial number 2. Then, valve port 111 with serial number 2 connects to valve port 111 with serial number 1 through the flow channel groove 211 of the distribution plate 220. Valve port 111 with serial number 1 connects to the first water pump 2001, liquid cooling condenser 2002 and electric heater 2003 to valve port 111 with serial number 11. Valve port 111 with serial number 11 flows through valve ports 111 with serial numbers 13, 8 and 10 in the flow channel groove 211 to form a loop. This loop is the water path of battery 4002. Meanwhile, valve port 111 with serial number 11 is also connected to valve port 111 with serial number 12. Valve port 111 with serial number 12 is connected to the water heater of the cockpit heating module 6000, and then connected to the water inlet of the first water pump 2001 to form a parallel water circuit.

[0143] The thermal management system also includes a first three-way valve 8000. When the thermal management system is in the sixth operating mode, the battery circulation module 4000 is connected in series with the first three-way valve 8000 and then connected to the first heat exchange module 2000 through an integrated water valve 1000. The three-way valve has a first port 8001, a second port 8002, and a third port 8003. The first port 8001 is connected to the downstream outlet of the battery circulation module 4000. The second port 8002 and the third port 8003 are connected to different valve ports 111 of the integrated water valve 1000. Specifically, the second port 8002 is connected to the port 111 of the integrated water valve 1000. The valve port 111 of 2 is connected, and the third interface 8003 is connected to the valve port 111 of serial number 9. Through the flow channel groove 211, the valve port 111 of serial number 9 is connected to the valve port 111 of serial number 10 to regulate the flow rate through the battery circulation module 4000. By adjusting the speed of the first water pump 2001 and the second water pump 4001, the flow rate is reasonably distributed between the first water pump 2001 and the second water pump 4001, ensuring the rationality of the flow rate and related heat exchange, preventing the battery 4002 from overheating and causing safety problems during the heating process of the water source heat pump, and improving the safety of the thermal management system.

[0144] This circuit is the cooling water circuit between battery 4002 and the cockpit, enabling the heating function of battery 4002 and the cockpit.

[0145] Another loop is as follows: valve port 111 with serial number 3 is connected to the third water pump 5001 and the second heat exchanger 5002 to valve port 111 with serial number 6. Then, inside the distribution plate 220, valve port 111 with serial number 6 is connected to valve port 111 with serial number 7. Valve port 111 with serial number 7 is connected to the first heat exchanger 3001 and the electric drive module 3002 to valve port 111 with serial number 5. Then, it is connected to valve port 111 with serial number 3 through the distribution plate 220 to form a closed loop. This loop is an electric drive loop.

[0146] This circuit differs from the sixth working mode. When the electric drive heat source is sufficient, valve port 111 with serial number 4 is not opened, and valve port 111 with serial number 5 is opened, and the first heat exchanger 3001 and the electric drive module 3002 are connected in series.

[0147] Please see Figure 14 In the seventh working mode, the first electric drive module 3000 is connected to the first heat exchange module 2000, and the first heat exchange module 2000 is connected in parallel with the cockpit heating module 6000. The battery circulation module 4000 is connected to the second heat exchange module 5000, so as to realize the cockpit heating and dehumidification and the electric drive module heat dissipation.

[0148] In this seventh operating mode, the sequence number and water flow direction of the internal flow channel connection valve port 111 of the distribution plate 220 of the integrated water valve 1000 are 5→1, 11→13→8→7, and parallel 11→12, 6→10, 2→3. The structural design of the flow channel groove 211 corresponding to the seventh zone 218 of the distribution plate 220 is as follows: Figure 5 As shown, the seventh zone 218 has four sets of flow channel grooves 211 of different shapes, each corresponding to a valve port 111.

[0149] The integrated water valve 1000 has two external circuits. One circuit connects the first electric drive module 3000 and the first heat exchange module 2000 through valve ports 111 (numbered 5, 1, 11, 13, 8, 7) to form a closed loop. Simultaneously, the first heat exchange module 2000 and the cockpit heating module 6000 are connected in parallel between port 12 and one end of the first heat exchange module 2000's water inlet, forming a parallel circuit between the electric drive and the cockpit. The other circuit connects the battery circulation module 4000 and the second heat exchange module 5000 through valve ports 111 (numbered 3, 6, 10, 2) to form a closed loop, which is the battery 4002 circuit.

[0150] In the thermal management system, under the seventh operating mode, the water flow direction is as follows: valve port 111 (number 1) connects to the first water pump 2001, liquid-cooled condenser 2002, and electric heater 2003 to valve port 111 (number 11). From valve port 111, the water flows sequentially through valve ports 13, 8, and 7 in the flow channel 211, then connects to the first heat exchanger 3001 and electric drive module 3002 to valve port 5 (number 5), and finally connects to valve port 111 (number 1), forming a loop. Simultaneously, valve port 111 (number 11) also connects to valve port 111 (number 12). Valve port 111 (number 12) connects to the water heater of the cockpit heating module 6000, and then connects to the inlet of the first water pump 2001, forming a parallel water circuit. Another water path is connected from valve port 111 (number 10) to valve port 111 (number 2), which is connected to the second water pump 4001 and battery 4002. Then, valve port 111 (number 2) is connected to valve port 111 (number 3) via the flow channel 211 of the distribution plate 220. Valve port 111 (number 3) is connected to valve port 111 (number 6) via the third water pump 5001 and the second heat exchanger 5002. Valve port 111 (number 6) flows through valve port 111 (number 10) in the flow channel 211 to form a loop. This loop is the water path for battery 4002.

[0151] Of course, in this seventh working mode, a first three-way valve 8000 is also provided. The battery circulation module 4000 is connected in series with the first three-way valve 8000 and then connected to the first heat exchange module 2000 through an integrated water valve 1000. The three-way valve has a first port 8001, a second port 8002, and a third port 8003. The first port 8001 is connected to the downstream outlet of the battery circulation module 4000. The second port 8002 and the third port 8003 are connected to different valve ports 111 of the integrated water valve 1000. Specifically, the second port 8002 is connected to the valve port numbered 2. The third interface 8003 is connected to valve port 111 (number 9) and, through flow channel 211, valve port 111 (number 9) is connected to valve port 111 (number 10) to regulate the flow rate through the battery circulation module 4000. By adjusting the speed of the first water pump 2001 and the second water pump 4001, the flow rate is reasonably distributed between the first water pump 2001 and the second water pump 4001, ensuring the rationality of the flow rate and related heat exchange, preventing the battery 4002 from overheating and causing safety problems during the water source heat pump heating process, and improving the safety of the thermal management system.

[0152] In the seventh operating mode, the heat from the battery 4002 circuit can be transferred to the cockpit circuit through heat exchange between the refrigerant side and the water side of the liquid-cooled condenser 2002 and the evaporator. At the same time, the refrigerant cooling cycle is activated in the cockpit circuit, thereby realizing the heating and dehumidification function of the cockpit. The heat source for heating comes from the battery 4002, and the excess heat from the battery 4002 is dissipated through the electric drive module.

[0153] Please see Figure 15 In the eighth working mode, the first electric drive module 3000 and the second heat exchange module 5000 are connected to dissipate heat from the electric drive module.

[0154] In this eighth working mode, the sequence number and water flow direction of the internal flow channel connecting valve port 111 of the distribution plate 220 of the integrated water valve 1000 are 5→3 and 6→7, respectively. The structural design of the flow channel groove 211 in the eighth zone 219 of the distribution plate 220 is as follows: Figure 5 As shown, the eighth zone 219 has two sets of flow channel grooves 211, each corresponding to a valve port 111. The external circuit of the integrated water valve 1000 is connected to the first electric drive module 3000 and the second heat exchange module 5000 through valve ports 111 numbered 5, 3, 6, and 7 to form a closed loop.

[0155] In the eighth working mode of the thermal management system, the water flow direction is connected to the first heat exchanger 3001 and the electric drive module 3002 through valve port 111 (number 7) to valve port 111 (number 5). Valve port 111 (number 5) is connected to valve port 111 (number 3) through flow channel groove 211. Valve port 111 (number 3) is connected to the third water pump 5001 and the second heat exchanger 5002 to valve port 111 (number 6). Finally, it is connected to valve port 111 (number 7) through flow channel groove 211, forming a closed loop.

[0156] The eighth working mode circuit is relatively simple and is used for heat dissipation of the electric drive system, dissipating the heat of the electric drive module into the air through the first heat exchanger 3001.

[0157] The eight operating modes described above, through different docking areas 210 of the integrated water valve 1000, connect with different modules of the thermal management system to form loops, achieving different functions. The adjustment method is simple, and the modes are diverse. The drive component 300 rotates the distribution plate 220 to achieve flow channel combinations in specific modes, connecting different water circuits to meet the different water circuit combination requirements of the corresponding system. This changes the water flow direction, realizes multi-loop mode switching and water flow control, thereby meeting the cooling or heating requirements of the thermal management system. Compared with traditional thermal management systems, this reduces the number of components in the architecture, simplifies the structure of the thermal management system, reduces the complexity of thermal management system control, and facilitates modular and platform-based porting of the thermal management system for further integrated development.
