Description

Technical Field

[0001] This application relates to the field of thermal management technology, and in particular to a control valve integrated module, a thermal management system, and a vehicle. Background Technology

[0002] To enhance the driving experience, vehicle thermal management systems are typically equipped with numerous modules for thermal management of different spaces or components within the vehicle.

[0003] In related technologies, in order to achieve separate management of different spaces or components by the thermal management system, the existing thermal management system is equipped with corresponding pipelines and various valves with different functions for the thermal management modules of different spaces or components. Different pipelines are arranged independently and various valves are installed independently in the pipelines, resulting in a large number of thermal management system components, a dispersed structure, complex pipeline connections, high space occupation, and difficult and time-consuming assembly, which is not conducive to the platform design of vehicles. Summary of the Invention

[0004] The purpose of this application is to provide a control valve integrated module, a thermal management system, and a vehicle, aiming to solve the problems of how to improve the integration of components and structure of the thermal management system, and simplify its structure and reduce its space occupation.

[0005] In a first aspect, this application provides a control valve integration module for use in a thermal management system. The control valve integration module includes a valve body and multiple external interfaces. The valve body has a flow channel for refrigerant flow in the thermal management system. The multiple external interfaces are disposed on the valve body and communicate with the flow channel. At least some of the external interfaces are adapted to connect to an electrically controlled heat exchange module in the thermal management system to allow refrigerant to circulate between the flow channel and the electrically controlled heat exchange module. And / or, at least some of the external interfaces are adapted to connect to a motor heat exchange module in the thermal management system to allow refrigerant to circulate between the flow channel and the motor heat exchange module.

[0006] According to the control valve integration module of this application, by setting multiple external interfaces on the valve body, the multiple external interfaces can be used to connect different thermal management modules in the thermal management system. The flow channel in the valve body can simultaneously connect with multiple different thermal management modules and provide flow paths for the refrigerant required by them. In this way, it is no longer necessary to configure separate pipelines and interface components for each thermal management module, which can reduce the number of independent parts in the thermal management system, thereby making the structure of the thermal management system simple and easy to assemble.

[0007] Furthermore, by integrating the electronically controlled heat exchange module and / or the motor heat exchange module into the refrigerant-using thermal management system via this control valve integration module, the characteristic of refrigerant absorbing a large amount of latent heat during evaporation (phase change cooling) allows for the removal of more heat with a smaller flow rate. Compared to traditional cooling methods such as water cooling, this enhances the heat dissipation capacity of the electronically controlled heat exchange module for the electronic components, and / or enhances the heat dissipation capacity of the motor heat exchange module for the motor components. Moreover, the refrigerant has a low boiling point, typically lower than water, allowing it to undergo a phase change at a lower temperature, thereby maintaining the electronically controlled components and / or motor components at a lower operating temperature. Thus, the thermal management system with this control valve integration module enables more effective thermal management of the electronically controlled components and / or motor components, preventing performance degradation at high temperatures due to heat generation.

[0047] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0048] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0050] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, where the range of similarity is within an acceptable deviation range, wherein the acceptable deviation range is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, a deviation within 15°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, a deviation within 15°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0051] See Figures 1-7In some embodiments, this application provides a control valve integration module 1, which can be used in a thermal management system 10. The control valve integration module 1 may include a valve body 2 and multiple external interfaces. The valve body 2 has a flow channel for supplying refrigerant flow in the thermal management system 10. Multiple external interfaces are located on the valve body 2 and communicate with the flow channel. At least some of the external interfaces are adapted to connect to an electrically controlled heat exchange module in the thermal management system 10 to allow refrigerant to circulate between the flow channel and the electrically controlled heat exchange module. And / or, at least some of the external interfaces are adapted to connect to a motor heat exchange module in the thermal management system 10 to allow refrigerant to circulate between the flow channel and the motor heat exchange module.

[0052] It should be noted that the refrigerant in the thermal management system 10 can be used to exchange heat with the target device or target space, for example, to cool or heat it.

[0053] Optionally, multiple interfaces can be detachably connected to the valve body 2; or, multiple interfaces can be integrally formed with the valve body 2.

[0054] The electronically controlled heat exchange module can be used for thermal management of the vehicle's electronic control components. Specifically, the electronically controlled heat exchange module can be used for heat exchange with the electronic control components. Optionally, the electronically controlled heat exchange module can be a cold plate.

[0055] The electronically controlled heat exchange module is connected to the control valve integration module 1 via an external interface. This allows the control valve integration module 1 to control the thermal management process of the electronically controlled components. Simultaneously, the refrigerant in the thermal management system 10 can be effectively delivered to the electronically controlled heat exchange module through the control valve integration module 1 to achieve thermal management of the electronically controlled components. Utilizing the characteristic of refrigerant absorbing a large amount of latent heat during evaporation (phase change cooling), more heat can be removed with a smaller flow rate. Compared to traditional cooling methods such as water cooling, this improves the heat dissipation capacity of the electronically controlled heat exchange module for the electronically controlled components. Furthermore, the refrigerant has a low boiling point, typically lower than water, allowing it to undergo a phase change at a lower temperature, thereby maintaining the electronically controlled components at a lower operating temperature.

[0056] In other related technologies, the electronic control subsystem used for thermal management of electronic control components in the thermal management system 10 is arranged independently, requiring separate pipelines 30, drive pumps 70, and interfaces. By using the control valve integration module 1, the separate electronic control subsystem and the other subsystems can be integrated together, which is beneficial to improve the integration of the thermal management system 10 and can also reduce the arrangement of pipelines 30. Thus, when the control valve integration module 1 and the thermal management system 10 are applied to a vehicle, the complexity of the whole vehicle thermal management system 10 can be reduced, space can be saved, and leakage points can be reduced.

[0057] In some alternative embodiments, the electronic control component may include at least one of a motor controller, a compressor controller, and a heater controller. For example, the electronic control component may include any one, any two, or all three of the motor controller, compressor controller, and heater controller.

[0058] When the electrical control component includes at least one of a motor controller, a compressor controller, and a heater controller, the motor controller, compressor controller, and heater controller include a control chip and a power module, wherein the power module belongs to the high-voltage section. When the electrical component includes a high-voltage device of the electrical control component, the electrical component may include power devices in the power module of the motor controller, compressor controller, and heater controller, or it may also include capacitors in the power module of the motor controller, compressor controller, and heater controller.

[0059] During the operation of the electronic control components, the aforementioned high-voltage devices are characterized by high current carrying capacity and large heat generation. By integrating the electronic control heat exchange module into the thermal management system 10 through the control valve integration module 1, the electronic control heat exchange module can remove the generated heat to reduce their operating temperature, improve their working efficiency, operational stability and service life, and avoid performance degradation or failure caused by local overheating, thereby helping to ensure the normal operation of the on-board charger and electronic control components.

[0060] The motor heat exchange module can be used for thermal management of the vehicle's motor assembly. Specifically, the motor heat exchange module can exchange heat with the motor assembly. For example, the motor heat exchange module can be configured as a liquid cooling channel for the motor housing or a stator cooling jacket.

[0061] The motor heat exchange module is connected to the control valve integration module 1 via an external interface. This allows the control valve integration module 1 to control the operation of the motor heat exchange module, meaning it controls the thermal management process of the motor assembly. Simultaneously, the refrigerant in the thermal management system 10 can be effectively delivered to the motor heat exchange module under the control of the control valve integration module 1 to achieve thermal management of the motor assembly. Utilizing the characteristic of refrigerant absorbing a large amount of latent heat during evaporation (phase change cooling), more heat can be removed with a smaller flow rate, thus improving the heat dissipation capacity of the motor heat exchange module for the motor assembly. Furthermore, the refrigerant has a low boiling point, allowing it to undergo a phase change at a lower temperature, thereby maintaining the motor assembly at a lower operating temperature.

[0062] In other related technologies, the motor subsystem used for thermal management of the motor assembly in the thermal management system 10 is arranged independently, requiring separate piping 30, drive pump 70, and interfaces. By using the control valve integration module 1, the separate electronic control subsystem and the other subsystems can be integrated together, which helps to improve the integration of the thermal management system 10 and also reduces the arrangement of piping 30. Thus, when the control valve integration module 1 and the thermal management system 10 are applied to a vehicle, the complexity of the whole vehicle thermal management system 10 can be reduced, space can be saved, and leakage points can be reduced.

[0063] See Figure 1 For example, at least some of the external interfaces are adapted to connect to the electrically controlled heat exchange module in the thermal management system 10. During the operation of the thermal management system 10, the refrigerant may have the following flow path: After flowing out of the outlet end of the drive pump 70 of the thermal management system 10, the refrigerant flows through the pipeline 30 to one of the external interfaces of the control valve integration module 1, and enters the flow channel of the valve body 2 through this external interface. After the refrigerant enters the flow channel inside the valve body 2, according to the current thermal management requirements, such as when the temperature of the electronic control components (such as inverters, power components) rises, the electronic control components need to be cooled. The control valve integration module 1 guides the refrigerant to the external interface connected to the electrically controlled heat exchange module. The refrigerant flows out through this interface, enters the electrically controlled heat exchange module, absorbs heat in its internal flow channel, and achieves cooling. After completing the heat exchange, the refrigerant flows out of the electrically controlled heat exchange module, returns to the flow channel of the valve body 2 through another external interface of the control valve integration module 1 connected to the electrically controlled heat exchange module, and is then guided to the system's return pipeline 30, returning to the inlet end of the drive pump 70, completing one cycle.

[0064] For example, at least some of the external interfaces are adapted to connect to the motor heat exchange module in the thermal management system 10. During the operation of the thermal management system 10, the refrigerant may have the following flow path: After flowing out of the outlet end of the drive pump 70 of the thermal management system 10, the refrigerant flows through the pipeline 30 to one of the external interfaces of the control valve integration module 1, and enters the flow channel of the valve body 2 through this external interface. After the refrigerant enters the flow channel inside the valve body 2, according to the current thermal management requirements, such as when the temperature of the motor assembly reaches the required cooling threshold, the motor assembly needs to be cooled, and the control valve integration module 1 can distribute the refrigerant to the motor heat exchange module. The control valve integration module 1 guides the refrigerant to the external interface connected to the motor heat exchange module. The refrigerant flows out through this interface, enters the motor heat exchange module, absorbs heat in its internal flow channel, and achieves cooling. After heat exchange, the refrigerant flows out from the motor heat exchange module and returns to the valve body 2 flow channel through another external interface of the control valve integration module 1 connected to the motor heat exchange module. It is then guided to the system's return line 30 and returns to the inlet end of the drive pump 70, completing one cycle.

[0065] For example, at least some of the external interfaces are adapted to connect the electronically controlled heat exchange module and the motor heat exchange module in the thermal management system 10. During the operation of the thermal management system 10, the refrigerant can have the following flow path: after flowing out of the outlet end of the drive pump 70 of the thermal management system 10, the refrigerant flows through the pipeline 30 to one of the external interfaces of the control valve integration module 1, and enters the flow channel of the valve body 2 through the external interface. After the refrigerant enters the flow channel inside the valve body 2, according to the current thermal management requirements, such as when the temperature of the electronic control components (e.g., inverter, power components) rises, the electronic control components need to be cooled; at the same time, when the temperature of the motor components reaches the cooling threshold, the refrigerant in the flow channel can be divided into two paths.

[0066] The control valve integration module 1 directs one refrigerant stream to the external interface of the electronically controlled heat exchange module. The refrigerant flows out through this interface, enters the electronically controlled heat exchange module, absorbs heat in its internal flow channels, and achieves cooling. After heat exchange, the refrigerant flows out of the electronically controlled heat exchange module, returns to the valve body 2 flow channel through another external interface of the control valve integration module 1 connected to the electronically controlled heat exchange module, and is then guided to the system's return line 30, returning to the inlet of the drive pump 70, completing one cycle. Simultaneously, the control valve integration module 1 directs another refrigerant stream to the external interface of the motor heat exchange module. The refrigerant flows out through this interface, enters the motor heat exchange module, absorbs heat in its internal flow channels, and achieves cooling. After heat exchange, the refrigerant flows out of the motor heat exchange module, returns to the valve body 2 flow channel through another external interface of the control valve integration module 1 connected to the motor heat exchange module, and is then guided to the system's return line 30, returning to the inlet of the drive pump 70, completing one cycle.

[0067] At least some of the external interfaces are adapted to connect to the electronically controlled heat exchange module in the thermal management system 10, which may include the following situations: for example, some external interfaces may be adapted to connect to the electronically controlled heat exchange module in the thermal management system 10, and other external interfaces may be adapted to connect to other thermal management modules in the thermal management system 10, such as battery heat exchange modules or air conditioning modules; as another example, some external interfaces may be adapted to connect to the electronically controlled heat exchange module in the thermal management system 10, and other external interfaces may be adapted to connect to the drive pump 70 of the thermal management system 10, so that the refrigerant can enter the control valve integration module under the action of the drive pump 70, and can flow to the electronically controlled heat exchange module through some of the external interfaces.

[0068] At least some of the external interfaces are adapted to connect to the motor heat exchange module in the thermal management system 10, which may include the following situations: for example, some external interfaces may be adapted to connect to the motor heat exchange module in the thermal management system 10, and other external interfaces may be adapted to connect to other thermal management modules in the thermal management system 10, such as battery heat exchange modules or air conditioning modules; as another example, some external interfaces may be adapted to connect to the motor heat exchange module in the thermal management system 10, and other external interfaces may be adapted to connect to the drive pump 70 of the thermal management system 10, so that the refrigerant can enter the control valve integration module under the action of the drive pump 70, and can flow to the motor heat exchange module through some of the external interfaces.

[0069] At least some of the external interfaces are adapted to connect to the electronically controlled heat exchange module and the motor heat exchange module in the thermal management system 10. This can include the following scenarios: for example, some external interfaces are adapted to connect to the electronically controlled heat exchange module and the motor heat exchange module in the thermal management system 10, while other external interfaces can be adapted to connect to other thermal management modules in the thermal management system 10, such as a battery heat exchange module or an air conditioning module; as another example, some external interfaces can be adapted to connect to the electronically controlled heat exchange module and the motor heat exchange module in the thermal management system 10, while other external interfaces can be adapted to connect to the drive pump 70 of the thermal management system 10, so that the refrigerant can enter the control valve integrated module under the action of the drive pump 70, and can flow to the electronically controlled heat exchange module and the motor heat exchange module through some of the external interfaces.

[0070] Of course, the multiple external interfaces can also be used to connect other thermal management modules in the thermal management system 10, such as the battery heat exchange module, and this application does not impose any specific restrictions on this.

[0071] For example, at least some of the external interfaces can be one, two, or more external interfaces.

[0072] According to the control valve integration module 1 of this application, by setting multiple external interfaces on the valve body 2, the multiple external interfaces can be used to connect different thermal management modules in the thermal management system 10. The flow channel in the valve body 2 can simultaneously connect with multiple different thermal management modules and provide a flow path for the refrigerant required by them. In this way, it is no longer necessary to configure separate pipes 30 and interface components connected to each thermal management module, which can reduce the number of independent parts in the thermal management system 10, thereby making the structure of the thermal management system 10 simple and easy to assemble.

[0073] Furthermore, by integrating the electronically controlled heat exchange module and / or the motor heat exchange module into the refrigerant-using thermal management system 10 via the control valve integration module 1, the refrigerant's characteristic of absorbing a large amount of latent heat during evaporation (phase change cooling) allows it to remove more heat with a smaller flow rate. Compared to traditional cooling methods such as water cooling, this improves the heat dissipation capacity of the electronically controlled heat exchange module for the electronic components, and / or improves the heat dissipation capacity of the motor heat exchange module for the motor components. Moreover, the refrigerant has a low boiling point, typically lower than water, allowing it to undergo a phase change at a lower temperature, thereby maintaining the electronically controlled components and / or motor components at a lower operating temperature. Thus, the thermal management system 10 with this control valve integration module can achieve more effective thermal management of the electronically controlled components and / or motor components, preventing performance degradation at high temperatures due to heat generation.

[0074] Furthermore, the centralized design of multiple external interfaces makes the external connection points more organized, reducing the probability of incorrect or missing connections. The design of the pipes 30 inside the valve body 2 also helps to reduce the risk of refrigerant / coolant leakage caused by aging or vibration of the pipes 30.

[0075] See Figure 1 and combined Figures 12-15 In some embodiments, the flow channel includes a first main flow path and a second branch and a third branch arranged in parallel. The second branch is located between the first main flow path and one end of the electronically controlled heat exchange module, and the third branch is located between the first main flow path and one end of the motor heat exchange module.

[0076] The control valve integration module 1 includes a first throttle valve 5, which is located in the second branch; the control valve integration module 1 also includes a second throttle valve 6, which is located in the third branch.

[0077] For example, the first main flow path can serve as the main channel for refrigerant, connecting to the outlet end of the drive pump 70 of the thermal management system 10. High-pressure liquid refrigerant is diverted to the second and third branches via the first main flow path. In the second branch, it can enter the electrically controlled heat exchange module via the first throttle valve 5, and in the third branch, it can enter the motor heat exchange module via the second throttle valve 6.

[0078] Optionally, the opening degree of the first throttle valve 5 and the second throttle valve 6 can be dynamically adjusted according to the heat generated by the electronic control component or the motor component. When the electronic control component generates a lot of heat, the first throttle valve 5 can be opened wider to increase the refrigerant flow and improve the cooling capacity. When the electronic control component generates little heat, the first throttle valve 5 can be closed narrowly to reduce the refrigerant flow and avoid over-cooling. When the motor component generates a lot of heat, the second throttle valve 6 can be opened wider to increase the refrigerant flow and improve the cooling capacity. When the motor component generates little heat, the second throttle valve 6 can be closed narrowly to reduce the refrigerant flow and avoid over-cooling.

[0079] The flow path of the refrigerant in the flow channel can be jointly controlled by the opening and closing states and opening degrees of the first throttling valve 5 and the second throttling valve 6, achieving independent or coordinated cooling of different heat sources. Furthermore, the opening degrees of the first throttling valve 5 and the second throttling valve 6 can be adjusted according to the thermal management requirements of the electronically controlled heat exchange module and the motor heat exchange module. This effectively ensures the heat exchange effect of the refrigerant in the corresponding heat exchange module while preventing excessive refrigerant from entering the electronically controlled heat exchange module and the motor heat exchange module.

[0080] In addition, by integrating the first throttle valve 5 and the second throttle valve 6 into the control valve integration module 1, the number of independent components in the system can also be reduced.

[0081] See Figure 1 and combined Figures 12-15 In some embodiments, the flow channel includes a second main flow path and a sixth branch path and a seventh branch path arranged in parallel. The sixth branch path is located between the second main flow path and the other end of the electronically controlled heat exchange module, and the seventh branch path is located between the second main flow path and the other end of the motor heat exchange module.

[0082] The control valve integration module 1 includes a fifth throttle valve 11, which is located in the sixth branch; the control valve integration module 1 also includes a fourth throttle valve 9, which is located in the seventh branch.

[0083] For example, the second main flow path is connected to the inlet of the drive pump 70 of the thermal management system 10, so that the refrigerant in the control valve integration module can flow to the drive pump 70. The refrigerant after heat exchange flows out from the electronically controlled heat exchange module and enters the sixth branch. The refrigerant after heat exchange enters the seventh branch from the motor heat exchange module. The refrigerant flows into the second main flow path after the pressure is throttled and regulated by the fifth throttle valve 11 in the sixth branch. The refrigerant also flows into the second main flow path after the pressure is throttled and regulated by the fourth throttle valve 9 in the seventh branch.

[0084] Optionally, the first throttle valve 5, the second throttle valve 6, the fifth throttle valve 11, and the fourth throttle valve 9 can be electronic expansion valves, large-diameter expansion valves, or zigzag-type electronic expansion valves. For example, the first throttle valve 5 and the second throttle valve 6 are zigzag-type electronic expansion valves, and the fifth throttle valve 11 and the sixth throttle valve 9 are large-diameter expansion valves. The throttle valves can be used to regulate the pressure or control the flow of refrigerant in the thermal management system 10, or they can also be used to control the on / off state of the refrigerant flow path.

[0085] By setting the fifth throttle valve 11 and the fourth throttle valve 9, the refrigerant flow pressure at the outlet of the electronically controlled heat exchange module and the motor heat exchange module can be adjusted accordingly. The flow speed of the sixth and seventh branches can also be adjusted accordingly, thereby controlling the back pressure and refrigerant residence time inside the electronically controlled heat exchange module and the motor heat exchange module, and avoiding insufficient heat exchange due to excessive refrigerant backflow in a certain branch.

[0086] See Figures 1-7 In some optional embodiments, the plurality of external interfaces include a second interface 36 and a sixth interface 40, wherein the second interface 36 is located between the second branch and one end of the electrically controlled heat exchange module, and the sixth interface 40 is located between the sixth branch and the other end of the electrically controlled heat exchange module.

[0087] Multiple external interfaces include a third interface 35 and a seventh interface 41. The third interface 35 is located between the third branch and one end of the motor heat exchange module, and the seventh interface 41 is located between the seventh branch and the other end of the motor heat exchange module.

[0088] The heat exchange flow path of the electrically controlled heat exchange module can be as follows: First, high-pressure refrigerant enters the integrated module. The refrigerant flows from the high-pressure side of the thermal management system 10 into the first main flow path of the control valve integrated module 1 through an external interface. Then, the refrigerant is diverted to the second branch. After being throttled and depressurized by the second throttling valve 6, it enters the electrically controlled heat exchange module (absorbing heat and evaporating) through the second interface 36. After the heat exchange is completed in the electrically controlled heat exchange module, the refrigerant (gas or gas-liquid mixture) returns from the outlet of the electrically controlled heat exchange module to the sixth branch through the sixth interface 40. After being regulated by the fifth throttling valve 11 (which adjusts the refrigerant pressure flowing into the second main flow path), it flows into the second main flow path.

[0089] The heat exchange flow path of the motor heat exchange module can be as follows: First, high-pressure refrigerant enters the integrated module. The refrigerant flows from the high-pressure side of the thermal management system 10 into the first main flow path of the control valve integrated module 1 via an external interface. Next, the refrigerant is diverted to a third branch. The third branch is equipped with a third throttling valve 7, where the refrigerant undergoes throttling and pressure reduction, changing from a high-pressure liquid state to a low-pressure, low-temperature gas-liquid mixture. The refrigerant after throttling and pressure reduction enters the motor heat exchange module (absorbing heat and evaporating) through the third interface 35. After the heat exchange is completed in the motor heat exchange module, the refrigerant (in gaseous or gas-liquid mixture) returns from the outlet of the motor heat exchange module to the seventh branch via the seventh interface 41, and is then regulated by the fourth throttling valve 9 (which adjusts the refrigerant pressure flowing back into the second main flow path) before flowing into the second main flow path.

[0090] It is understandable that the refrigerant pressure after being regulated by the fifth throttle valve 11 is equal to the refrigerant pressure after being regulated by the sixth throttle valve 9.

[0091] See Figures 1-7 In some embodiments, multiple external interfaces are also adapted to connect to the battery heat exchange module of the thermal management system 10, so that the refrigerant circulates between the flow channel and the battery heat exchange module. The battery heat exchange module can be used for thermal management of the vehicle's battery device; specifically, the battery heat exchange module can exchange heat with the battery device. Optionally, the battery heat exchange module can be a cold plate.

[0092] The battery heat exchange module is connected to the control valve integration module 1 via an external interface. In this way, the control valve integration module 1 can control the thermal management process of the electronic control components. At the same time, the refrigerant in the thermal management system 10 can be effectively delivered to the battery heat exchange module through the control of the control valve integration module 1 to achieve thermal management of the battery device.

[0093] See Figures 1-7 In some embodiments, multiple external interfaces are also adapted to connect to the air conditioning module of the thermal management system 10 to allow refrigerant to circulate between the flow channel and the air conditioning module. Optionally, the air conditioning module may include an external condenser, an internal evaporator, and an internal condenser. The air conditioning module can be used to cool or heat the passenger compartment of the vehicle.

[0094] The air conditioning module is connected to the control valve integration module 1 via an external interface, so that the control valve integration module 1 can control the thermal management process of the target space, such as the passenger compartment of a vehicle; at the same time, the refrigerant in the thermal management system 10 can be effectively delivered to the air conditioning module through the control of the control valve integration module 1 to achieve thermal management of the target space.

[0095] In some alternative embodiments, multiple external interfaces are also adapted to connect to the refrigerator module of the thermal management system 10, such as the refrigerator evaporator adapted to connect to the refrigerator module.

[0096] See Figures 2-11 In some embodiments, the multiple external interfaces include multiple first external interfaces 3, which are located on one side of the valve body 2 and are adapted to connect to the electrically controlled heat exchange module and / or the motor heat exchange module in the thermal management system 10. The control valve integration module 1 also includes multiple control valve interfaces 4, which are located on the other side of the valve body 2. This facilitates the connection operation of the multiple external interfaces and the multiple control valve interfaces 4.

[0097] See Figures 1-11 In some embodiments, the valve body 2 includes a plurality of connecting pipe sections 21 and a plurality of integrated pipe sections 22. The plurality of connecting pipe sections 21 and the plurality of integrated pipe sections 22 form flow channels. At least a portion of the plurality of integrated pipe sections 22 communicates with at least a portion of the plurality of connecting pipe sections 21. The extending direction of the plurality of integrated pipe sections 22 is perpendicular to the extending direction of at least one connecting pipe section 21. The extending direction of the integrated pipe section 22 can be seen as direction e3 in the figure, and the extending direction of the connecting pipe section 21 can be seen as direction e2 in the figure.

[0098] Furthermore, the control valve integration module 1 includes a valve body 2, multiple first external interfaces 3, and multiple control valve interfaces 4. The multiple first external interfaces 3 can be connected to at least a portion of the multiple integrated pipe sections 22, and the multiple control valve interfaces 4 can be connected to at least a portion of the multiple integrated pipe sections 22. For example, the multiple first external interfaces 3 are located at one end of the multiple integrated pipe sections 22, and the multiple control valve interfaces 4 are located at the other end of the multiple integrated pipe sections 22.

[0099] Optionally, an integrated pipe section 22 may be connected to both an external interface and a control valve interface 4, or it may be connected to only an external interface or a control valve interface 4. This application does not impose any specific restrictions on this.

[0100] For example, multiple connecting pipe sections 21 can form a first main flow path and a second main flow path with flow channels, and multiple integrated pipe sections 22 can form a second branch path, a third branch path, a fifth branch path, and a sixth branch path with flow channels.

[0101] The extension direction of the plurality of integrated pipe sections 22 is perpendicular to the extension direction of at least one connecting pipe section 21, which may include the following situations: for example, the extension direction of the plurality of integrated pipe sections 22 may be perpendicular to the extension direction of one of the connecting pipe sections 21; for another example, the extension direction of the plurality of integrated pipe sections 22 may be perpendicular to the extension direction of several of the connecting pipe sections 21; and for yet another example, the extension direction of the plurality of integrated pipe sections 22 may be perpendicular to the extension directions of all of the plurality of integrated pipe sections 22.

[0102] Optionally, multiple connecting pipe sections 21 can be arranged on the same layer, and the extension direction of multiple integrated pipe sections 22 can be perpendicular to the layer where the multiple connecting pipe sections 21 are located. That is, the extension direction of multiple integrated pipe sections 22 can be perpendicular to the extension direction of multiple integrated pipe sections 22.

[0103] "Multiple connecting pipe sections 21 are arranged on the same layer" means that multiple connecting pipe sections 21 are arranged in the same three-dimensional space plane or approximately the same plane, and the extension directions of the multiple connecting pipe sections 21 are located on the same plane, parallel or intersecting each other.

[0104] Wherein, at least a portion of the plurality of integrated pipe sections 22 is connected to at least a portion of the plurality of connecting pipe sections 21, which may include the following situations: for example, a portion of the plurality of integrated pipe sections 22 is connected to a portion of the plurality of connecting pipe sections 21; for another example, a portion of the plurality of integrated pipe sections 22 is connected to the entire plurality of connecting pipe sections 21; and for yet another example, the entire plurality of integrated pipe sections 22 is connected to the entire plurality of connecting pipe sections 21.

[0105] Optionally, the multiple integrated pipe sections 22 can be divided into multiple groups, and the arrangement direction of each group of integrated pipe sections 22 is perpendicular to the plane where the multiple connecting pipe sections 21 are located.

[0106] Optionally, the multiple first external interfaces 3 and multiple control valve interfaces 4 can be integrally formed with the valve body 2, or the multiple first external interfaces 3 and multiple control valve interfaces 4 can be separately set and connected to the valve body 2.

[0107] The first external interface 3 can be used to connect to subsystems of the thermal management system 10, such as battery heat exchange module, motor heat exchange module, etc., and the control valve interface 4 can be used to connect various control valves to realize control of different modes of the thermal management system 10.

[0108] Optionally, multiple first external interfaces 3 are adapted to connect to the battery subsystem, electronic control subsystem, motor subsystem, and air conditioning subsystem of the thermal management system 10.

[0109] Optionally, the multiple first external interfaces 3 are also adapted to connect to the refrigerator subsystem of the thermal management system 10.

[0110] If multiple control valves (such as solenoid valves, three-way valves, etc.) are installed independently in different positions, and each valve is connected to the main circuit through bends and joints, a large number of in-plane intersecting pipe networks 30 are formed, resulting in a large number of parts and complex connections. By integrating multiple connecting pipe sections 21, multiple integrated pipe sections 22, multiple first external interfaces 3 and multiple control valve interfaces 4 into the valve body 2, the internal flow channels are interconnected within the valve body 2, which greatly reduces the number and length of external connection pipes 30. This is beneficial to improve the integration level of the thermal management system 10, reduce the number of parts and reduce the complexity of connections.

[0111] All connecting pipe sections 21 and integrated pipe sections 22 are integrated into a single valve body 2, forming a standardized module. This also allows for "modular pre-assembly," meaning that the control valve integrated module 1 is installed and tested as a whole before final assembly, and then connected to the system in one go. This significantly reduces the time spent installing valves and welding / fastening pipes 30 individually on-site, improving the level of automated assembly.

[0112] Multiple control valve interfaces 4 are centrally located, which facilitates unified management of the operation of each control valve by the electronic control unit. The control valves can be centrally installed at the corresponding control valve interface 4, which is conducive to centralized wiring and improves EMC performance.

[0113] Placing all the connecting pipe sections 21 and the integrated pipe section 22 in the same plane would result in a large area being occupied. By making the extending directions of the multiple integrated pipe sections 22 perpendicular to the extending direction of at least one connecting pipe section 21, the integrated pipe section 22 can make full use of the space perpendicular to the extending direction of the connecting pipe section 21. When the control valve integrated module 1 is applied to a vehicle, the projected area of ​​the control valve integrated module 1 on the vehicle's mounting plane can be effectively reduced.

[0114] Optionally, the first external interface 3 can be a quick-connect connector, an O-ring seal, a threaded port, etc.

[0115] According to the control valve integration module 1 of this application, by integrating multiple connecting pipe sections 21 and multiple integrated pipe sections 22 on the valve body 2, and by centrally arranging multiple control valve interfaces 4 and multiple first external interfaces 3 on the integrated pipe section 22, the functions of multiple independent valves and their connecting pipes 30 that are traditionally distributed are integrated into the valve body 2 module, which helps to reduce the number of independent components in the thermal management system 10, thereby making the structure of the thermal management system 10 simple and easy to assemble.

[0116] In addition, by making the extension direction of multiple integrated pipe sections 22 perpendicular to the extension direction of at least one connecting pipe section 21, multiple connecting pipe sections 21 and multiple integrated pipe sections 22 can form a "three-dimensional cross" structure, utilizing three-dimensional space for flow channel layout. This avoids the control valve integrated module 1 being too large in a certain direction due to the planar arrangement of all pipe sections, thereby avoiding the resulting waste of space and thus facilitating the optimization of the spatial arrangement of the thermal management system 10.

[0117] See Figures 6-7 In some embodiments, the assembly of multiple integrated pipe sections 22 has a first side and a second side, with multiple control valve interfaces 4 located on the first side and multiple first external interfaces 3 located on the second side. The first side is one side of the assembly of multiple integrated pipe sections, and the other sides are the second side. This facilitates the installation of control valves on the first side via the control valve interfaces 4, and the arrangement of pipes 30 of each subsystem of the thermal management system 10 on the second side via the first external interfaces 3. This arrangement helps minimize size. When the control valve integration module 1 is applied to a vehicle, it facilitates vehicle layout and platformization, optimizes the front compartment space layout, and makes the overall vehicle layout neater.

[0118] See Figures 2-5 In some embodiments, along the arrangement direction of the plurality of integrated pipe sections 22, a plurality of connecting pipe sections 21 are located between a plurality of first external interfaces 3 and a plurality of control valve interfaces 4.

[0119] Multiple connecting pipe sections 21 are arranged on the same layer, and the arrangement direction of multiple integrated pipe sections 22 is perpendicular to the layer where the multiple connecting pipe sections 21 are located. The multiple connecting pipe sections 21 are interconnected in the same layer, and the integrated pipe section 22 passes through one end of the valve body 2 to the other end and is connected to the connecting pipe section 21 at the intersection.

[0120] This helps to further reduce the space occupied by the control valve integration module 1. At the same time, it also makes it easier for the control valve and the subsystems of the thermal management system 10 to make full use of the space on both sides of the multiple connecting pipes 21, that is, the space at both ends of the valve body 2.

[0121] See Figures 2-5In some embodiments, multiple integrated pipe sections 22 and multiple connecting pipe sections 21 are staggered. Optionally, the multiple integrated pipe sections 22 and multiple connecting pipe sections 21 can be staggered along a first direction, wherein the extending direction of the integrated pipe sections 22 is perpendicular to the first direction, and the extending direction of the connecting pipe sections 21 is also perpendicular to the first direction. The first direction can be seen as direction e1 in the figure. The multiple integrated pipe sections 22 and multiple connecting pipe sections 21 are spatially distributed with avoidance, which helps to reduce the space occupied by the multiple connecting pipe sections 21 and multiple first integrated pipe sections 251 along the first direction.

[0122] See Figures 1-11 In some embodiments, at least a portion of the plurality of integrated pipe sections 22 are arranged along the length direction of a plurality of connecting pipe sections 21. For example, the plurality of integrated pipe sections 22 may be arranged along the length direction of one connecting pipe section 21; for example, the plurality of integrated pipe sections 22 may be divided into several groups, and each group of integrated pipe sections 22 may be arranged along the length direction of one connecting pipe section 21; for example, a plurality of integrated pipe sections 22 may be arranged along the length direction of each connecting pipe section 21.

[0123] This layout of multiple integrated pipe sections and multiple connecting pipe sections 21 is reasonable, and the overall structure of the valve body 2 is compact.

[0124] See Figures 2-6 In some embodiments, the valve body 2 further includes a reinforcing portion 23, which is disposed between the connecting pipe portion 21 and the connecting pipe portion 21. This is beneficial to improving the connection strength between the multiple connecting pipe portions, and thus to improving the structural strength of the control valve integrated module 1.

[0125] See Figures 2-6 In some embodiments, the reinforcing part 23 is disposed between the integrated tube section 22 and the integrated tube section 22. This helps to improve the connection strength between the multiple integrated tube sections 22, and thus helps to improve the structural strength of the control valve integrated module 1.

[0126] See Figures 2-6 In some embodiments, the reinforcing part 23 is disposed between the connecting pipe part 21 and the integrated pipe part 22. This helps to improve the structural strength of the control valve integrated module 1.

[0127] See Figures 1-11 In some embodiments, the valve body 2, multiple first external interfaces 3, and multiple control valve interfaces 4 are integrally formed. This helps reduce the assembly steps of the control valve integration module 1 and further improves the production efficiency of the control valve integration module 1.

[0128] See Figures 1-11 In some alternative embodiments, the valve body 2, the plurality of first external interfaces 3 and the plurality of control valve interfaces 4 can be integrally die-cast.

[0129] See Figures 2-3 In some embodiments, at least two connecting pipe sections 21 are arranged parallel to each other and opposite to each other. That is, two or more connecting pipe sections 21 among a plurality of connecting pipe sections 21 can be arranged parallel to each other and opposite to each other. For example, at least two connecting pipe sections 21 can be arranged parallel to each other along a first direction or a second direction, both of which are parallel to the plane in which the plurality of connecting pipe sections 21 are located, and the first direction and the second direction intersect.

[0130] This reduces the space occupied by multiple connecting pipe sections 21 arranged in a certain direction, thereby helping to reduce the size of the control valve integration module 1 in a certain direction.

[0131] See Figures 2-3 In some alternative embodiments, a plurality of integrated tube sections 22 may be disposed on one side of two parallel connecting tube sections 21 opposite to the other.

[0132] See Figures 2-11 and combined Figures 13-14 In some embodiments, a plurality of connecting pipe sections 21 form a first connecting pipe group 24. The first connecting pipe group 24 includes at least one connecting pipe section 21 and has a plurality of first connecting ports 201 arranged along the length direction of the connecting pipe section 21. That is, the first connecting pipe group 24 may include one or more connecting pipe sections 21, and the connecting pipe sections 21 of the first connecting pipe group 24 are interconnected.

[0133] At least some of the integrated tube sections 22 are connected to a plurality of first communication ports 201, and the integrated tube sections 22 connected to the first communication ports 201 form a first integrated tube group 25.

[0134] The first integrated pipe assembly 25 includes at least one integrated pipe section 22, which is connected to a first communication port 201. Specifically, the plurality of first communication ports 201 are connected to a plurality of control valve interfaces 4 provided in the first integrated pipe assembly 25, that is, the plurality of control valve interfaces 4 provided in the first integrated pipe assembly 25 are connected to the plurality of first communication ports 201 and the plurality of first external interfaces 3 provided in the first integrated pipe assembly 25.

[0135] For example, the refrigerant in the thermal management system 10 can enter an integrated pipe section 22 through an external pipe 30 via one of the first external interfaces 3. The refrigerant flows through the control valve interface 4 of the integrated pipe section 22 and then enters the connecting pipe section 21 of the first connecting pipe group 24 via the first connecting port 201.

[0136] For example, the connecting pipe section 21 of the first connecting pipe group 24 may also have a second external interface 32. The refrigerant in the thermal management system 10 may also enter the connecting pipe section 21 of the first connecting pipe group 24 through the second external interface 32 via the external pipe 30, and then enter the corresponding integrated pipe section 22 through multiple first connecting ports 201 respectively.

[0137] The connecting pipe section 21 of the first connecting pipe group 24 forms the main flow path. Multiple branch paths connected to the main flow path can be formed through multiple first connecting ports 201. Specifically, the flow channel within the connecting pipe section 21 of the first connecting pipe group 24 can be the first main flow path, and the flow channels within the multiple integrated pipe sections 22 of the first integrated pipe group 25 form multiple branch paths connected to the first main flow path. The first main flow path and the multiple branch paths are connected through the first connecting ports 201. The refrigerant entering the connecting pipe section 21 of the first connecting pipe group 24 can enter the corresponding branch path through each first connecting port.

[0138] Multiple connecting pipe sections 21 and multiple integrated pipe sections 22 can be grouped according to their different functions in the thermal management system 10. This reduces the probability of missing connections, missing installations, incorrect connections, and incorrect installations during the assembly of the control valve integrated module 1 or its connection with other components of the thermal management system 10.

[0139] In some embodiments, the first connecting pipe group 24 includes a first connecting pipe section 241, a second connecting pipe section 242, and a third connecting pipe section 243 connected sequentially. An angle is formed between the first connecting pipe section 241 and the second connecting pipe section 242, and an angle is formed between the second connecting pipe section 242 and the third connecting pipe section 243. The first connecting pipe section 241, the second connecting pipe section 242, and the third connecting pipe section 243 cooperate to form a continuous first main flow path.

[0140] For example, the first connecting pipe section 241, the second connecting pipe section 242, and the third connecting pipe section 243 may be arranged in a "Z-shape", "U-shape", or "zigzag shape" or similar layout.

[0141] This helps to improve the overall structural compactness of the control valve integration module 1. When the control valve integration module 1 is applied to a vehicle, it can improve its adaptability to the layout space inside the vehicle. For example, it can better adapt to the small layout space of the front engine compartment of the vehicle.

[0142] See Figures 5-9In some embodiments, the first connecting pipe section 241 and the third connecting pipe section 243 are arranged parallel to each other along a first direction and opposite to each other. The first connecting pipe section 241 and the third connecting pipe section 243 are located on the same side of the second connecting pipe section 242 along a second direction, and the first direction and the second direction intersect. The first connecting pipe section 241 and the third connecting pipe section 243 are parallel to each other, and the second connecting pipe section 242 serves as a "bridging section" connecting one end of them. The three together form a semi-enclosed area, which can be used to arrange the integrated pipe section 22, thereby optimizing space utilization and avoiding space waste.

[0143] See Figures 5-9 In some embodiments, a portion of the integrated tube section 22 of the first integrated tube group 25 is located on one side of the first connecting tube section 241 along a first direction, and a portion of the integrated tube section 22 of the first integrated tube group 25 is located on one side of the third connecting tube section 243 along a first direction. Specifically, a portion of the integrated tube section 22 of the first integrated tube group 25 is arranged along the length direction of the first connecting tube section 241, and a portion of the integrated tube section 22 of the first integrated tube group 25 is arranged along the length direction of the third connecting tube section 243.

[0144] For example, a portion of the integrated tube section 22 of the first integrated tube group 25 is located along the first direction on the side of the first connecting tube section 241 facing the third connecting tube section 243, and another portion of the integrated tube section 22 of the first integrated tube group 25 is located along the first direction on the side of the third connecting tube section 243 facing the first connecting tube section 241. That is, the integrated tube section 22 of the first integrated tube group 25 can make full use of the space defined between the first connecting tube section 241 and the second connecting tube section 242.

[0145] For example, a portion of the first integrated pipe assembly 25 is located along the first direction on the side of the first connecting pipe section 241 away from the third connecting pipe section 243, and another portion of the first integrated pipe assembly 25, the integrated pipe section 22, is located along the first direction on the side of the third connecting pipe section 243 facing the first connecting pipe section 241. This can reduce the difficulty of arranging the integrated pipe assembly.

[0146] For example, the first integrated tube group 25 includes five integrated tube sections 22, wherein three integrated tube sections 22 are located on one side of the first connecting tube section 241 along the first direction, and the other two integrated tube sections 22 are located on one side of the third connecting tube section 243 along the first direction.

[0147] By arranging the integrated pipe section 22 of the first integrated pipe group 25 in the first connecting pipe section 241 and the third connecting pipe section 243, the arrangement of multiple integrated pipe sections 22 can make full use of the space along the first direction and reduce the space occupation along the second direction. The overall structural layout of the control valve integrated module 1 is reasonable and the distribution of each part is regular.

[0148] See Figures 5-9In some optional embodiments, the first integrated tube group 25 includes a first integrated tube section 251, a second integrated tube section 252, a third integrated tube section 253, a fourth integrated tube section 254, and a fifth integrated tube section 255. The first integrated tube section 251, the second integrated tube section 252, and the third integrated tube section 253 are arranged along the length direction of the first connecting tube section 241 on one side of the first connecting tube section 241, and the fourth integrated tube section 254 and the fifth integrated tube section 255 are arranged along the length direction of the third connecting tube section 243 on one side of the third connecting tube section 243.

[0149] The flow channel within the second integrated tube section 252 can be formed as a second branch, and the first throttle valve 5 can be located at the control valve interface 4 corresponding to the second integrated tube section 252. The flow channel within the third integrated tube section 253 can be formed as a third branch, and the second throttle valve 6 can be located at the control valve interface 4 corresponding to the third integrated tube section 253.

[0150] See Figures 5-9 In some embodiments, the plurality of external interfaces further includes a second external interface 32, which is disposed in the connecting pipe portion 21 of the first connecting pipe assembly 24. The second external interface 32 is adapted to connect to the external condenser of the thermal management system 10. Optionally, the second external interface 32 may be disposed in the first connecting pipe portion 241, the second connecting pipe portion 242, or the third connecting pipe portion 243. Optionally, the second external interface 32 may be disposed at the end or side of the connecting pipe portion 21 of the first connecting pipe assembly 24. For example, the second external interface 32 may be disposed at the end of the first connecting pipe portion 241 away from the second connecting pipe portion 242.

[0151] By providing a second external interface 32, the refrigerant in the thermal management system 10 can directly enter or exit the main flow path formed by the first connecting pipe section 241 via the second external interface 32. Furthermore, this optimizes the vehicle's thermal management architecture, reduces the complexity of the external piping 30, and allows the control valve integration module 1, acting as the "thermal management hub," to be uniformly connected to the external condenser via the second external interface 32. This avoids the need for multiple subsystems (such as the battery, motor, and air conditioning) connected to the first external interface 3 to each have their own piping 30. When the control valve integration module 1 is applied to a vehicle, it simplifies the layout of the vehicle's thermal piping 30, reducing assembly difficulty and space requirements.

[0152] For example, the external condenser is connected between the inlet end of the drive pump 70 and the second external interface 32 of the thermal management system 10. The drive pump 70 can drive the refrigerant to flow through the external condenser and then enter the main flow path of the first connecting pipe 241 through the second external interface 32.

[0153] See Figures 4-9In some embodiments, one end of the second connecting pipe 242 is provided with a first port 2421. The first port 2421 facilitates the processing and forming of the control valve integrated module 1.

[0154] See Figures 4-9 In some embodiments, a second port 2431 is provided at one end of the third connecting pipe 243. The provision of the second port 2431 facilitates the processing and forming of the control valve integrated module 1.

[0155] See Figure 4 In some optional embodiments, a sealing cap 203 is provided at the first port 2421 and the second port 2431 to prevent refrigerant leakage into the control valve integration module 1, thereby meeting the sealing requirements of the thermal management system 10.

[0156] See Figures 1-11 In some embodiments, the first external interface 3 connected to the first connecting pipe group 24 forms a first interface group, which includes a first interface 37 adapted to connect to the in-vehicle condenser of the thermal management system 10. Specifically, the first interface 37 may be located in the first integrated pipe section 251.

[0157] The in-vehicle condenser is used to heat the passenger compartment of the vehicle. Thus, the control valve integration module 1 can control the operation of the in-vehicle condenser; that is, the control valve integration module 1 can control the heating process of the passenger compartment by the in-vehicle condenser. Combined with the control valve at the other end of the integrated pipe section 22 where the first interface 37 is located, the start / stop or flow regulation of the in-vehicle condenser during operation can be achieved.

[0158] See Figures 1-11 In some embodiments, the first interface group includes a second interface 36, which is adapted to connect to the electrically controlled heat exchange module of the thermal management system 10. Specifically, the second interface 36 may be located in the second integrated tube section 252.

[0159] In this way, the control valve integration module 1 can control the operation of the electronically controlled heat exchange module, that is, the control valve integration module 1 can control the thermal management process of the electronically controlled components. Combined with the control valve at the other end of the integrated tube section 22 where the second interface 36 is located, the start / stop, flow regulation, or cooling / heating mode adjustment in the thermal management process of the electronically controlled components can be realized.

[0160] See Figures 1-11 In some embodiments, the first interface group includes a third interface 35, which is adapted to connect to the motor heat exchange module of the thermal management system 10. Specifically, the third interface 35 may be located in the third integrated tube section 253.

[0161] In this way, the control valve integration module 1 can control the operation of the motor heat exchange module, that is, the control valve integration module 1 can control the thermal management process of the motor assembly. Combined with the control valve at the other end of the integrated tube section 22 where the third interface 35 is located, the start / stop, flow regulation, or cooling / heating mode adjustment in the thermal management process of the motor assembly can be realized.

[0162] See Figures 1-11 In some embodiments, the first interface group includes a fourth interface 38, which is adapted to connect to the in-vehicle evaporator of the thermal management system 10. Specifically, the fourth interface 38 may be located in the fourth integrated pipe section 254.

[0163] The in-vehicle evaporator can be used to cool or heat the passenger compartment of the vehicle. Thus, the control valve integration module 1 can control the operation of the in-vehicle evaporator, meaning it can control the cooling or heating process of the passenger compartment by the in-vehicle evaporator. Combined with the control valve at the other end of the integrated pipe section 22 where the fourth interface 38 is located, it is possible to start / stop the in-vehicle evaporator, adjust the flow rate, or regulate the cooling / heating mode during operation.

[0164] See Figures 1-11 In some embodiments, the first interface group includes a fifth interface 39, which is adapted to connect to the battery heat exchange module of the thermal management system 10. Specifically, the fifth interface 39 may be located in the fifth integrated tube section 255.

[0165] In this way, the control valve integration module 1 can control the operation of the battery heat exchange module, that is, the control valve integration module 1 can control the thermal management process of the battery device. Combined with the control valve at the other end of the integrated tube section 22 where the fourth interface 38 is located, the start / stop, flow regulation, or cooling / heating mode adjustment in the thermal management process of the battery device can be realized.

[0166] By setting up a first interface group, each of the first external interfaces 3 of the first interface group can connect the air conditioning subsystem, motor subsystem, electronic control subsystem, battery subsystem, etc. of the thermal management system 10 to the control valve integration module 1. In this way, the control valve integration module 1 can realize independent control or collaborative control of each subsystem.

[0167] See Figures 2-11 In some optional embodiments, three integrated tube sections 22 with a first interface 37, a second interface 36 and a third interface 35 are arranged along the length direction of the first connecting tube section 241, and two integrated tube sections 22 with a fourth interface 38 and a fifth interface 39 are arranged along the length direction of the third connecting tube section 243.

[0168] See Figures 2-11 and combined Figure 12 In some embodiments, a plurality of connecting pipe sections 21 form a second connecting pipe group 26. The second connecting pipe group 26 includes at least one connecting pipe section 21 and has a plurality of second connecting ports 202 arranged along the length direction of the connecting pipe section 21. That is, the second connecting pipe group 26 may include one or more connecting pipe sections 21, and the connecting pipe sections 21 of the second connecting pipe group 26 can be interconnected.

[0169] A plurality of integrated tube sections 22 are correspondingly connected to a plurality of second communication ports 202. The integrated tube sections 22 connected to the second communication ports 202 form a second integrated tube group 27. The second integrated tube group 27 includes at least one integrated tube section 22, and at least one integrated tube section 22 of the second integrated tube group 27 is respectively connected to the plurality of second communication ports 202. That is, the second integrated tube group 27 may include one or more integrated tube sections 22.

[0170] Specifically, multiple second connection ports 202 are connected to multiple control valve interfaces 4 located in the second integrated pipe group 27. In other words, multiple control valve interfaces 4 located in the second integrated pipe group 27 are connected to multiple second connection ports 202 and multiple first external interfaces 3 located in the second integrated pipe group 27.

[0171] For example, the refrigerant in the thermal management system 10 can enter an integrated pipe section 22 of the second connecting pipe group 26 from an external pipe 30 through one of the first external interfaces 3. The refrigerant flows through the control valve interface 4 of the integrated pipe section 22 and then enters the connecting pipe section 21 of the second connecting pipe group 26 through the first connecting port 201.

[0172] For example, the connecting pipe section 21 of the second connecting pipe group 26 may also be formed with a third external interface 28, through which the refrigerant entering the connecting pipe section 21 of the second connecting pipe group 26 may flow out of the control valve integration module 1 via the third external interface 28.

[0173] The flow channels within the connecting pipe section 21 of the second connecting pipe group 26 can form a second main flow path, and the flow channels within the multiple integrated pipe sections 22 of the second integrated pipe group 27 can form multiple branch paths connecting to the second main flow path. The second main flow path and the multiple branch paths are connected through the second connecting port 202. The refrigerant flowing through each integrated pipe section 22 of the second integrated pipe group 27 can flow into the second main flow path of the second connecting pipe group via the branch paths of the second connecting port 202.

[0174] Multiple connecting pipe sections 21 and multiple integrated pipe sections 22 can be grouped according to their different functions in the thermal management system 10. This reduces the probability of missing connections, missing installations, incorrect connections, and incorrect installations during the assembly of the control valve integrated module 1 or its connection with other components of the thermal management system 10.

[0175] The first connecting pipe group 24, the first integrated pipe group 25, the second connecting pipe group 26, and the second integrated pipe group 27 cooperate with each other to realize the refrigerant inflow and outflow control valve integrated module 1 of the thermal management system 10.

[0176] For example, the refrigerant of the thermal management system 10 can enter the control valve integration module 1 via the first connecting pipe group 24 and the first integrated pipe group 25, and then flow out of the control valve integration module 1 via the second connecting pipe group 26 and the second integrated pipe group 27.

[0177] For example, the refrigerant of the thermal management system 10 can enter the control valve integration module 1 via the second connecting pipe group 26 and the second integrated pipe group 27, and then flow out of the control valve integration module 1 via the first connecting pipe group and the first integrated pipe group 25.

[0178] See Figures 2-11 In some optional embodiments, the first connecting pipe group 24 and the second connecting pipe group 26 are independent, that is, the first connecting pipe group 24 and the second connecting pipe group 26 are not directly connected.

[0179] See Figures 2-11 In some alternative embodiments, along the first direction, the second connecting pipe group 26 and the second integrated pipe group 27 are located on one side of the first connecting pipe group 24 as a whole. Specifically, the second connecting pipe group 26 and the second integrated pipe group 27 may be located on the side of the third connecting pipe section 243 away from the first connecting pipe section 241.

[0180] See Figures 5-9 In some embodiments, the second connecting pipe group 26 includes a fourth connecting pipe section 261, and a portion of the integrated pipe section 22 of the second integrated pipe group 27 is located at one end of the fourth connecting pipe section 261. Optionally, there may be one or more integrated pipe sections 22 located at one end of the fourth connecting pipe section 261, and multiple integrated pipe sections 22 may be arranged side by side at one end of the fourth connecting pipe section 261. In this way, the spatial layout of the second connecting pipe group 26 and the second integrated pipe group 27 is reasonable, and the second integrated pipe group 27 makes full use of the space around the fourth connecting pipe group.

[0181] Optionally, another part of the integrated tube section 22 of the second integrated tube group 27 may be located on one side of the fourth connecting tube section 261, and this part of the integrated tube section 22 may be arranged along the length direction of the fourth connecting tube section 261.

[0182] For example, the second integrated tube group 27 includes three integrated tube sections 22, wherein two integrated tube sections 22 are located on one side of the fourth connecting tube section 261 along the first direction, and the other integrated tube section 22 is located at one end of the fourth connecting tube section 261.

[0183] See Figures 5-9In some optional embodiments, the second integrated tube group 27 includes a sixth integrated tube section 272, a seventh integrated tube section 273 and an eighth integrated tube section 274. The sixth integrated tube section 272 and the seventh integrated tube section 273 are located on one side of the fourth connecting tube section 261 along the length direction of the fourth connecting tube section 261, and the eighth integrated tube section 274 is located at one end of the fourth connecting tube section 261.

[0184] The flow channel within the sixth integrated tube section 272 can be formed as a sixth branch, and the fifth throttle valve 11 can be located at the control valve interface 4 corresponding to the sixth integrated tube section 272. The flow channel within the seventh integrated tube section 273 can be formed as a seventh branch, and the fourth throttle valve 9 can be located at the control valve interface 4 corresponding to the seventh integrated tube section 273.

[0185] See Figures 5-9 In some embodiments, the plurality of external interfaces also include a third external interface 28, which is disposed in the connecting pipe portion 21 of the second connecting pipe group 26 and is adapted to connect to the inlet end of the drive pump 70 of the thermal management system 10.

[0186] Optionally, the third external interface 28 can be located at the end or side of the connecting pipe portion 21 of the second connecting pipe assembly 26. For example, the third external interface 28 can be located at the other end of the fourth connecting pipe portion 261. Optionally, the drive pump 70 can be a compressor, a refrigerant pump, etc. Optionally, the third external interface 28 can also be a quick-connect fitting, an O-ring seal, a threaded connection, etc.

[0187] By setting a third external interface 28, the refrigerant in the thermal management system 10 can directly enter or exit the main flow path formed by the fourth connecting pipe section 261 via the third external interface 28. Furthermore, this optimizes the vehicle's thermal management architecture, reduces the complexity of the external piping 30, and allows the control valve integration module 1, acting as the "thermal management hub," to be uniformly connected to the inlet of the drive pump 70 via the third external interface 28. This avoids the need for multiple subsystems (such as the battery, motor, and air conditioning) connected to the first external interface 3 of the second integrated pipe group 27 to each have their own piping 30 connected to the inlet of the drive pump 70. When the control valve integration module 1 is applied to a vehicle, it simplifies the layout of the vehicle's thermal piping 30, reducing assembly difficulty and space occupation.

[0188] See Figures 1-11In some embodiments, the first external interface 3 connected to the second connecting pipe group 26 forms a second interface group, which includes a sixth interface 40 adapted to connect to the electrically controlled heat exchange module of the thermal management system 10. That is, the electrically controlled heat exchange module can be connected at one end to the second interface 36 and at the other end to the sixth interface 40. For example, during the operation of the electrically controlled heat exchange module, the refrigerant in the thermal management system 10 can flow from the control valve integration module 1 to the electrically controlled heat exchange module via the second interface 36, and then flow back to the control valve integration module 1 via the sixth interface 40.

[0189] Specifically, the sixth interface 40 can be located in the sixth integrated tube section 272.

[0190] In this way, through the cooperation of the second interface 36 and the sixth interface 40 of the control valve integration module 1, a complete thermal management loop of the electronically controlled heat exchange module can be formed, so as to effectively connect the electronic control subsystem to the control valve integration module 1.

[0191] See Figures 1-11 In some embodiments, the second interface group includes a seventh interface 41, which is adapted to connect to the motor heat exchange module of the thermal management system 10. That is, the motor heat exchange module can be connected at one end to the third interface 35 and at the other end to the seventh interface 41. For example, during the operation of the motor heat exchange module, the refrigerant in the thermal management system 10 can flow from the control valve integration module 1 to the motor heat exchange module via the third interface 35, and then flow back to the control valve integration module 1 via the seventh interface 41.

[0192] Specifically, the seventh interface 41 can be located in the seventh integrated tube section 273.

[0193] In this way, through the cooperation of the third interface 35 and the seventh interface 41 of the control valve integration module 1, a complete thermal management loop of the electronically controlled heat exchange module can be formed to effectively connect the motor subsystem to the control valve integration module 1.

[0194] See Figures 1-11 In some optional embodiments, two integrated tube sections 22 with a sixth interface 40 and a seventh interface 41 are arranged along the length direction of the fourth connecting tube section 261.

[0195] See Figures 1-11 In some embodiments, the plurality of integrated pipe sections 22 located at one end of the fourth connecting pipe section 261 include an eighth integrated pipe section 274, and the second interface group includes an eighth interface 42. The eighth interface 42 is connected to the eighth integrated pipe section 274 and is adapted to connect to the outlet end of the drive pump 70 of the thermal management system 10. Specifically, the eighth interface 42 may be located at the other end of the eighth integrated pipe section 274.

[0196] For example, the refrigerant in the thermal management system 10 can flow out from the outlet of the drive pump 70 and enter the control valve integration module 1 via the eighth interface 42.

[0197] See Figures 1-11 In some embodiments, the plurality of external interfaces may further include a fourth external interface 44, which is located on the side of the eighth integrated tube section 274 away from the fourth connecting tube section 261. The fourth external interface 44 is adapted to connect to the battery heat exchange module of the thermal management system 10.

[0198] Optionally, the fourth external interface 44 can be a quick-connect connector, an O-ring seal, a threaded port, etc.

[0199] In other words, the battery heat exchange module can be connected to the fifth interface 39 at one end and to the fourth external interface 44 at the other end. Under different thermal management modes of the battery heat exchange module, the refrigerant in the thermal management system 10 can flow from the control valve integration module 1 to the battery heat exchange module via the first interface 37, and then flow back to the control valve integration module 1 via the fourth external interface 44; or, the refrigerant in the thermal management system 10 can flow from the control valve integration module 1 to the battery heat exchange module via the fourth external interface 44, and then flow back to the control valve integration module 1 via the first interface 37.

[0200] For example, the refrigerant in the thermal management system 10 can flow into the control valve integration module 1 via the first external interface 3 on the integrated pipe section 22 located at one end of the fourth connecting pipe section 261, flow through the control valve located at the corresponding control valve interface 4 to the fourth external interface 44, and then flow to the battery heat exchange module.

[0201] Both the eighth interface 42 and the fourth external interface 44 are connected to the flow path inside the eighth integrated pipe section 274. The control valve at the control valve interface 4 at the other end of the eighth integrated pipe section 274 can control the flow path of the pipe 30 connected to the eighth interface 42, control the flow path of the pipe 30 connected to the fourth external interface 44, or control the flow path between the pipes 30 corresponding to the eighth interface 42 and the fourth external interface 44.

[0202] In this way, the eighth integrated tube section 274 can be connected to two external pipes 30 through its eighth interface 42 and fourth external interface 44 respectively. The control valve located at the other end of the integrated tube section 22 can control the on / off of these two pipes 30 to meet the flow path requirements of more thermal management modes.

[0203] In some alternative embodiments, the second interface group may also include a ninth interface, wherein the in-vehicle evaporator may be connected at one end to the fourth interface 38 and at the other end to the ninth interface.

[0204] See Figures 1-11In some embodiments, the control valve integration module 1 further includes a selection control valve structure 8, which is disposed in the eighth integrated pipe section 274. The selection control valve interface 4 is used to selectively connect the eighth interface 42 and the third external interface 28, or to selectively connect the eighth interface 42 and the flow channel in the fourth connecting pipe section 261.

[0205] The selection control valve structure 8 has a first mode and a second mode and can switch between the two modes. In the first mode, the selection control valve structure 8 connects the flow path between the eighth interface 42 and the third external interface 28, and disconnects the flow path between the eighth interface 42 and the fourth connecting pipe 261. In the second mode, the selection control valve structure 8 connects the flow path between the eighth interface and the fourth connecting pipe 261, and disconnects the flow path between the eighth interface 42 and the third external interface 28.

[0206] By setting the selection control valve structure 8, multiple channels can be controlled simultaneously.

[0207] In other words, in some optional embodiments, the selection control valve structure 8 can be disposed opposite to the eighth interface 42 at both ends of the eighth integrated tube section 274.

[0208] See Figure 9 and Figure 12 In some optional embodiments, the control valve structure 8 can be a multi-way valve, such as a three-way valve. For example, the control valve structure 8 is selected as a three-way valve, which includes three valve ports: A1, B1, and C1. Valve port A1 is connected to the third external interface 28, valve port B1 is connected to the eighth interface 42, and valve port C1 is connected to the fourth connecting pipe 261. Thus, when A1-B1 are connected and C1 is closed, the third external interface 28 and the eighth interface 42 are connected, and the flow path within the eighth interface 42 and the fourth connecting pipe 261 is cut off; when B1-C1 are connected and A1 is closed, the third external interface 28 and the eighth interface 42 are cut off, and the flow path within the eighth interface 42 and the fourth connecting pipe 261 is connected.

[0209] See Figures 25-27 In some optional embodiments, the selection control valve structure 8 may include valve bodies 2 arranged in parallel. For example, the selection control valve structure 8 may include a first valve structure 104 and a second valve structure 105. The first valve structure 104 may be located in the eighth integrated pipe section 274 for controlling the flow path between the third external interface 28 and the eighth interface 42. The second valve structure 105 may also be located in the eighth integrated pipe section 274 for controlling the flow path between the eighth interface 42 and the main flow path of the fourth connecting pipe section 261. The second valve structure 105 may be located at the control valve interface 4 of the eighth integrated pipe section 274.

[0210] See Figures 1-11 In some optional embodiments, the control valve integration module 1 includes multiple control valves, which may include the first throttle valve 5, the second throttle valve 6, the fifth throttle valve 11, the fourth throttle valve 9, and the selection control valve structure 8 described above. Of course, the multiple control valves may also include other valve structures.

[0211] Multiple control valves can effectively realize the on / off relationship or flow regulation between each integrated pipe section 22 and the connecting pipe section 21, thereby realizing the flow path control of the heat exchange module connected to each integrated pipe section 22, so that the thermal management system 10 can realize diversified thermal management modes according to the actual needs of users.

[0212] See Figures 1-11 Optionally, the multiple control valves may also include a seventh throttle valve 13, with the first interface 37 and the seventh throttle valve 13 disposed opposite to each other at both ends of the first integrated tube section 251.

[0213] See Figures 1-11 Optionally, the multiple control valves may also include a third throttle valve 7, and the fourth interface 38 and the third throttle valve 7 are disposed opposite to each other at both ends of the fourth integrated tube section 254.

[0214] See Figures 1-11 Optionally, the multiple control valves may also include a sixth throttle valve 12, with the fifth interface 39 and the sixth throttle valve 12 disposed opposite to each other at both ends of the fifth integrated tube section 255.

[0215] See Figures 1-11 Optionally, the throttle valves of the control valve assembly 50 can be conventional electronic expansion valves or zigzag expansion valves. For example, the first throttle valve 5, the second throttle valve 6, and the seventh throttle valve 13 can be zigzag expansion valves, while the third throttle valve 7 and the sixth throttle valve 12 can be conventional expansion valves. The fourth throttle valve 9 and the fifth throttle valve 11 can also be zigzag expansion valves.

[0216] See Figures 1-11 Optionally, the multiple control valves can be divided into a first valve group and a second valve group. Both the first valve group and the second valve group include multiple control valve structures. The multiple control valve structures of the first valve group are correspondingly located at the multiple control valve interfaces 4 of the first integrated pipe group 25. The first valve group is used to control the on / off state or refrigerant flow between the first connecting pipe group and the multiple integrated pipe sections 22 of the first integrated pipe group 25.

[0217] The second valve group has multiple control valve structures corresponding to multiple control valve interfaces 4 of the second integrated pipe group 27, and the second valve group is used to control the on / off or refrigerant flow between the second connecting pipe group and multiple integrated pipe sections 22 of the second integrated pipe group 27.

[0218] The first valve group may include a first throttle valve 5, a second throttle valve 6, a third throttle valve 7, a sixth throttle valve 12, and a seventh throttle valve 13. The second valve group may include a fourth throttle valve 9 and a fifth throttle valve 11. The second valve group may also include a multi-way valve, such as a three-way valve. The eighth port 42 and the multi-way valve may be disposed opposite to each other at both ends of the eighth integrated tube section 274.

[0219] See Figures 2-5 In some embodiments, the control valve integration module 1 further includes a wiring harness assembly 20, which is located on one side of the integral assembly of multiple integrated pipe sections 22 and electrically connected to the control valve assembly 50. The wiring harness assembly 20 can be connected to the control module of the thermal management system 10 via a main wiring harness. The integrated wiring harness arrangement of multiple control valves is beneficial to improving electrical safety performance.

[0220] Specifically, the wire harness assembly 20 may be located on the first side of the integral assembly of multiple integrated tube sections 22.

[0221] See Figure 1 and combined Figures 16-17 In some embodiments, the control valve integration module 1 further includes a filter assembly 60, which is disposed within multiple control valve interfaces 4 and / or multiple first external interfaces 3. The filter assembly 60 can be used to intercept impurities such as solid particles, welding slag, oxides, and sealing material debris in the refrigerant of the thermal management system 10, effectively preventing blockages in the various heat exchange modules connected to the control valve integration module 1, thus ensuring good heat exchange performance. For example, it can prevent blockages in battery heat exchange modules, motor heat exchange modules, and electronic control heat exchange modules.

[0222] For example, the filter assembly 60 may be disposed within a plurality of control valve interfaces 4 or within a plurality of first external interfaces 3. For example, the filter assembly 60 may be disposed within both a plurality of control valve interfaces 4 and a plurality of first external interfaces 3.

[0223] By integrating the filter assembly 60 into the control valve integration module 1, the integration level of the thermal management system 10 can be further improved, and the filter assembly 60 can make full use of the space at each interface. In addition, the external piping 30 structure of the control valve integration module 1 does not need to be set up separately for connecting and fixing the filter assembly 60, which helps to simplify the connection structure of the piping 30.

[0224] See Figure 1 and combined Figures 16-17In some embodiments, the filter assembly 60 includes a first filter assembly 603, which is disposed within an external interface corresponding to the electrically controlled heat exchange module. For example, the first filter assembly 603 may be disposed in the second interface 36 or the sixth interface 40. For example, the first filter assembly 603 may be disposed in both the second interface 36 and the sixth interface 40.

[0225] By setting the first filter component 603 in the external interface corresponding to the electric heat exchange module, the flow path inside the electric heat exchange module can be effectively prevented from being blocked, so as to ensure that the electric heat exchange module can effectively complete the thermal management task. In this way, it can effectively prevent the heat of the electric control component from being unable to be dissipated in time due to blockage of the electric heat exchange module, which would cause damage or failure of the electric control component. In other words, this is also conducive to improving the working stability and safety of the electric control component.

[0226] See Figure 1 and combined Figures 16-17 In some embodiments, the filter assembly 60 includes a second filter assembly 604, which is disposed within the external interface corresponding to the motor heat exchange module. For example, the second filter assembly 604 may be disposed in the third interface 35 or the seventh interface 41. For example, the first filter assembly 603 may be disposed in both the third interface 35 and the seventh interface 41.

[0227] By setting a second filter component 604 in the external interface corresponding to the motor heat exchange module, blockage of the flow path in the motor heat exchange module can be effectively avoided, ensuring that the motor heat exchange module can effectively complete the thermal management task. This can effectively prevent the motor component from being damaged or malfunctioning due to the inability to dissipate heat in time caused by blockage of the motor heat exchange module. In other words, this also helps to improve the working stability and safety of the motor component.

[0228] See Figures 16-17 In some embodiments, the filter assembly 60 includes a filter element 601 and a sealing limiting member 602, with the sealing limiting member 602 located on the side of the filter element 601 facing away from the valve body 2. This improves the installation stability of the filter element 601 and enhances the sealing effect of the filter assembly 60, preventing impurities from flowing in or out through the gap between the filter assembly 60 and the valve body 2.

[0229] Optionally, the filter element 601 can be a filter screen, such as a funnel-shaped filter screen, to reduce the accumulation of impurities. The sealing and limiting element 602 can be made of HNBR or EPDM.

[0230] The assembly process of the filter assembly 60 may include the following steps: inserting the filter element 601 into the external interface of the valve body 2, and then pushing the filter element 601 and the sealing limit element 602 into the external interface in sequence. Each external interface forms two slots, one for accommodating the filter element 601 and the other for accommodating the sealing limiting element 602. The diameter B of the slot accommodating the sealing limiting element 602 is larger than the inner diameter A of the external interface, so that the sealing limiting element 602 is engaged in the slot with a snap-fit ​​effect, preventing the filter element 601 from falling out. The inner wall of the external interface is interference-fitted with the sealing limiting element 602 to prevent impurities from flowing in or out from the gap.

[0231] In some embodiments, the annual leakage of refrigerant at at least one external interface is less than or equal to 10g. For example, the annual leakage of refrigerant at at least one external interface can be 10g, 9g, 8.5g, 8g, 6g, or 5g, etc.

[0232] This can include the following scenarios: for example, the annual leakage of refrigerant at some or all external interfaces can be less than or equal to 10g; or, for example, the annual leakage of refrigerant at any external interface can be less than or equal to 10g.

[0233] Optionally, the annual leakage of refrigerant at at least one external interface is less than or equal to 8g. For example, the annual leakage of refrigerant at at least one external interface can be 8g, 6g, 5.8g, 4.5g, 4g, 3.6g, or 2g, etc.

[0234] Optionally, the annual leakage of refrigerant at at least one external interface is less than or equal to 6g. For example, the annual leakage of refrigerant at at least one external interface can be 6g, 5.5g, 4.1g, 4g, 3g, or 2.5g, etc.

[0235] Refrigerant is the core working fluid for heat transfer in the thermal management system 10, and its leakage will directly disrupt the system's operational balance. A reduction in the total amount of refrigerant will lead to a decrease in the performance of various thermal management modules in the thermal management system 10.

[0236] When this thermal management system is applied to a vehicle, the thermal management system 10 is equipped with an electronically controlled heat exchange module and a motor heat exchange module for thermal management of the motor assembly and electronic control components. Because the motor assembly and electronic control components operate at a higher frequency and for a longer duration during vehicle operation compared to other components or spaces requiring heat dissipation, they require heat dissipation more frequently and for longer periods. If refrigerant leakage occurs, the impact on the thermal management effect of the motor assembly and electronic control components is more significant, thus making the amount of refrigerant leakage more pronounced on the entire system. By ensuring that the annual refrigerant leakage at the external interface of the control valve integration module 1 is within a certain range, the adverse effects of refrigerant leakage on the thermal management effect of the thermal management system 10 can be reduced or avoided.

[0237] For example, during vehicle acceleration, the vehicle's electronic control components generate a significant amount of heat, requiring rapid heat dissipation. If the leakage is substantial, the refrigerant will gradually decrease, reducing the refrigerant's heat exchange capacity within the electronic control heat exchange module. This weakens the heat dissipation capacity for the electronic control components, leading to increased temperatures in components such as the IGBTs, potentially causing damage or performance degradation.

[0238] For example, when a vehicle is cruising at high speed or climbing a hill, the motor components continuously generate heat, requiring high cooling. If the leakage is large, it will lead to insufficient refrigerant, a decrease in the refrigerant heat exchange capacity within the motor heat exchange module, poor heat dissipation for the motor components, and a continuous rise in the motor winding temperature, which will shorten the motor's lifespan.

[0239] See Figures 2-11 and combined Figure 18 In some embodiments, at least one external interface is provided with a plurality of connection structures spaced circumferentially, the plurality of connection structures being adapted to connect to the piping 30 of the thermal management system 10. Exemplarily, one or more of the plurality of external interfaces are provided with a plurality of connection structures spaced circumferentially. Exemplarily, each external interface is provided with a plurality of connection structures spaced circumferentially.

[0240] By setting multiple connection structures around the external interface, the sealing effect between the external interface and the pipe 30 can be improved, and the amount of refrigerant leakage at the external interface can be reduced.

[0241] See Figures 2-11 and combined Figure 19 In some embodiments, at least one external interface has a circumferentially threaded structure, and the external interface is adapted to be threadedly connected to the pipe 30 of the thermal management system 10. Exemplarily, one or more of a plurality of external interfaces have a circumferentially threaded structure. Exemplarily, each external interface has a circumferentially threaded structure.

[0242] A circumferential threaded connection is formed between the external interface and the pipe 30, which can also improve the sealing effect of the connection between the external interface and the pipe 30 and reduce the amount of refrigerant leakage at the external interface.

[0243] See Figures 18-19 Optionally, the pipeline 30 may include a pipeline 30 body and a fixed connection structure. The pipeline 30 body and the external interface are plugged into each other. The fixed connection structure is connected to the pipeline 30 body and is used to fix the pipeline 30 body to the external interface.

[0244] For example, the fixed connection structure can be a fastener 301, which is fastened to the connection structure. For example, the valve body 2 has multiple connection holes 29, with at least two connection holes 29 spaced apart circumferentially at each external interface. Specifically, each external interface has two connection holes 29 arranged at 180°. The fastener 301 is a fastening screw, which is used to install the pipeline 30 onto the valve body 2. For example, the fixed connection structure can be a set of 30 pipes, which are threaded to the external interface. For example, the inner wall of the set of 30 pipes is threaded, the outer wall of the external interface of the valve body 2 is threaded, and the inner wall is smooth. The installation process is to insert the set of 30 pipes into the external interface of the valve body 2 and then tighten it through the threads of the set of 30 pipes.

[0245] See Figures 18-19 In some embodiments, the control valve integration module 1 further includes at least two seals, which are sealed between the external interface and the pipeline 30 of the thermal management system 10. That is, the control valve integration module 1 may include two or more seals. For example, at least two seals may be provided between one or more of the multiple external interfaces and the pipeline 30. For example, at least two seals may be provided between each external interface and the pipeline 30.

[0246] Using at least two seals between pipe 30 and the external interface helps ensure the reliability of the seal.

[0247] For example, the seal can be a sealing ring 303, which can be used to radially seal the pipe 30 and the external interface.

[0248] Optionally, at least two seals may be arranged along the insertion direction of the conduit 30 and the external interface.

[0249] See Figure 1 and Figure 25 In some embodiments, this application also provides a thermal management system 10, which includes the control valve integration module 1 described above.

[0250] The thermal management system 10 may further include an air conditioning subsystem, an electronic control subsystem, a motor subsystem, and a battery subsystem. The air conditioning subsystem includes an air conditioning module, which may include an external condenser, an internal evaporator, and an internal condenser. The electronic control subsystem includes an electronically controlled heat exchange module. The motor subsystem includes a motor heat exchange module, and the battery subsystem includes a battery heat exchange module.

[0251] The thermal management system 10 also includes a drive pump 70. The air conditioning subsystem, electrical control subsystem, motor subsystem and battery subsystem are all connected between the outlet end and the inlet end of the drive pump 70. The drive pump 70 is used to drive the refrigerant to flow through the heat exchange modules of each subsystem to effectively achieve heat exchange.

[0252] Specifically, the external condenser is connected between the outlet end of the drive pump 70 and the second external interface 32, the internal evaporator is connected between the fourth interface 38 and the inlet end of the drive pump, and the internal condenser is connected between the outlet end of the drive pump 70 and the first interface 37.

[0253] The electronically controlled heat exchange module is connected between the second interface 36 and the sixth interface 40, the motor heat exchange module is connected between the third interface 35 and the seventh interface 41, and the battery heat exchange module is connected between the fifth interface 39 and the third external interface 28.

[0254] The outlet end of the drive pump 70 is also connected to the eighth interface 42, and the inlet end of the drive pump 70 is also connected to the fourth external interface 44.

[0255] In some alternative embodiments, the drive pump 70 can be a compressor, a refrigerant pump, etc.

[0256] In some alternative embodiments, the thermal management system 10 may further include a refrigerator subsystem, which may be directly connected between the outlet and inlet of the drive pump 70. The thermal management system 10 may also include a ninth throttle valve 101, which is located in the refrigerator subsystem.

[0257] The refrigerator subsystem can also be connected between the outlet and inlet of the drive pump 70 via the control valve integration module 1.

[0258] In this way, when the thermal management system 10 is applied to a vehicle, the whole vehicle thermal management system 10 is integrated into a single system. The electronically controlled heat exchange module, which is used to manage the thermal of electronic components such as the compressor controller and motor controller, is integrated into the whole vehicle multi-in-one thermal management system 10, eliminating its separate water cooling system, reducing the number of parts, weight and space occupied, and also improving its heat dissipation effect.

[0259] In some optional embodiments, the thermal management system 10 further includes a conduit 30 for connecting the control valve integration module 1 and various subsystems of the thermal management system 10. For example, it can be used to connect multiple first external interfaces 3, second external interfaces 32, third external interfaces 28, fourth external interfaces 44, etc., to the battery subsystem, the electronic control subsystem, the motor subsystem, the air conditioning subsystem, etc.

[0260] Pipeline 30 can also be used to connect multiple control valves and battery subsystems, electrical control subsystems, motor subsystems, and air conditioning subsystems of control valve assembly 50.

[0261] In some optional embodiments, the conduit 30 is connected to the valve body 2, that is, the conduit 30 is connected to various external interfaces of the valve body 2, such as multiple first external interfaces 3, second external interfaces 32, third external interfaces 28, and fourth external interfaces 44. The end of the conduit 30 that connects to the valve body 2 is an interface end, and the interface end is provided with a fixing component, which is fixedly connected to the valve body 2.

[0262] In some alternative embodiments, the thermal management system 10 may also include a silencer that can be connected to the outlet of the drive pump 70, which helps to reduce noise in the thermal management system.

[0263] In some alternative embodiments, the thermal management system 10 further includes an eighth throttle valve 100 connected between the outlet of the drive pump 70 and the external condenser.

[0264] The thermal management system 10 also includes a tenth throttle valve 102, which is connected between the vehicle evaporator and the inlet of the drive pump 70.

[0265] By controlling the opening and closing of different control valve structures, the thermal management system 10 can achieve multiple thermal management modes.

[0266] See Figure 20 For example, the thermal management system 10 includes a first mode in which the battery pack can be heated and the motor assembly cooled. Specifically, in this mode, the sixth throttle valve 12, the second throttle valve 6, and the fourth throttle valve 9 are open, while the remaining valves are closed; the three-way valves B1-A1 flow inwards, while C1 is closed.

[0267] The drive pump 70 compresses and discharges the refrigerant, which is now a high-temperature, high-pressure gas. It flows into the three-way valve via the eighth port 42. The three-way valve (B1-A1) is connected to the battery heat exchange module. The gas flows out of the control valve integrated module 1 via the fourth external port 44, and then flows to the battery heat exchange module via pipeline 30. The low-temperature battery pack heats up after exchanging heat with the battery heat exchange module, and the refrigerant is cooled into a medium-temperature, high-pressure liquid. It then flows into the control valve integrated module 1 via the fifth port 39, and then into the sixth throttle valve 12. The refrigerant is throttled and cooled by the sixth throttle valve 12, becoming a low-temperature, low-pressure vapor-liquid two-phase mixture. Finally, it passes through the second throttle valve 6, which is now fully open and acts as a flow... The refrigerant is allowed to flow through the pipe, and then flows out of the control valve integrated module 1 through the third interface 35. It is connected to the motor heat exchange module through the pipe 30. At this time, the motor heat exchange module is an evaporator. The refrigerant is heated by the waste heat of the motor to complete the heat absorption and evaporation process from the environment. Then, the outlet of the motor heat exchange module is a low temperature and low pressure gas. Then, the outlet of the motor heat exchange module flows back to the control valve integrated module 1 through the seventh interface 41, and then flows out of the control valve integrated module 1 through the fourth throttle valve 9 and the third external interface 28. Then, it flows to the gas-liquid separator through the pipe 30. The gas-liquid separator separates the refrigerant and the refrigeration oil, and acts as an intermediate gas storage tank to ensure stable gas intake of the drive pump 70. Finally, the refrigerant returns to the drive pump 70, thus forming a cycle.

[0268] See Figure 21 For example, the thermal management system 10 includes a second mode in which battery pack cooling and motor assembly cooling can be achieved. The eighth throttle valve 100, the sixth throttle valve 12, the second throttle valve 6, and the fourth throttle valve 9 are open, while the remaining valves are closed; three-way valves A1-C1 allow flow, while B1 is closed.

[0269] The drive pump 70 compresses and discharges high-temperature, high-pressure gas, which is then connected to the external condenser via the eighth throttle valve 100. The refrigerant exchanges heat with the environment through the external condenser, releasing heat. The outlet of the external condenser is a medium-temperature, high-pressure liquid, which enters the storage tank, passes through a one-way valve, and flows into the control valve integrated module 1 via the second external interface 32. It then flows in two paths. The first path flows through the internal channel of the first connecting pipe 241 into the sixth throttle valve 12, where it expands into a low-temperature, low-pressure gas-liquid mixture. This mixture then flows out of the control valve integrated module 1 via the fifth interface 39 and enters the battery heat exchange module through pipe 30. In the battery heat exchange module, the refrigerant evaporates into a low-temperature, low-pressure gas, then flows into the control valve integrated module 1 via the fourth external interface 44. At this time, the three-way valves A1-C1 are open and the flow rate is adjusted, while B1 is closed. The mixture then flows out of the control valve integrated module 1 via the third external interface 28. The second path flows into the second throttle valve 6 (at this time, the flow rate is finely adjusted at a low opening), and then flows through the... The second throttling valve 6 expands the refrigerant into a low-temperature, low-pressure gas-liquid mixture, which then flows out of the control valve integrated module 1 through the third interface 35 and into the motor heat exchange module through the pipeline 30. In the heat exchange module, the refrigerant evaporates and absorbs heat to form a low-temperature, low-pressure gaseous refrigerant, which then flows into the control valve integrated module 1 through the seventh interface 41. After passing through the fourth throttling valve 9, it merges with the first refrigerant through the third external interface 28 and flows out of the control valve integrated module 1. Then, it flows to the gas-liquid separator through the pipeline 30. The gas-liquid separator separates the refrigerant and the refrigeration oil and acts as an intermediate gas storage device to ensure stable gas intake of the drive pump 70. Finally, the refrigerant returns to the drive pump 70, thus forming a cycle.

[0270] See Figure 22 For example, the thermal management system 10 includes a third mode in which dehumidification of the passenger compartment and cooling of the motor components can be achieved. In this mode, the seventh throttle valve 13, the second throttle valve 6, the third throttle valve 7, the fourth throttle valve 9, and the tenth throttle valve 102 are open, and the remaining valves are closed; the three-way valves B1-C1 flow inward, and A1 is closed.

[0271] The drive pump 70 compresses and discharges high-temperature, high-pressure gas, which then splits into two paths. The first path flows into the vehicle's condenser, where the refrigerant condenses and absorbs heat to become a medium-temperature, high-pressure liquid. This liquid then flows through the first interface 37 into the control valve integrated module 1, and then through the seventh throttle valve 13, which is now fully open. Here, it splits into two branches. The first branch flows into the third throttle valve 7, where it expands into a low-temperature, low-pressure gas-liquid mixture. This mixture then flows through the fourth interface 38 out of the control valve integrated module 1, and then through pipe 30 into the vehicle's evaporator, where it evaporates inside the vehicle. The gaseous refrigerant evaporates and absorbs heat in the generator, forming a low-temperature, low-pressure gaseous state, and then flows through the tenth throttle valve 102. The second branch flows into the second throttle valve 6 (at this time, the flow rate is finely adjusted at a low opening). After being throttled by the second throttle valve 6, the gaseous refrigerant expands into a low-temperature, low-pressure gas-liquid mixture and then flows out of the control valve integrated module 1 through the third interface 35. It then flows into the motor heat exchange module through the pipeline 30. After evaporating and absorbing heat in the motor heat exchange module, it forms a low-temperature, low-pressure gaseous refrigerant, which then flows into the control valve integrated module 1 through the seventh interface 41. After passing through the fourth throttle valve 9, it flows through the third external interface 28. The second path flows into the control valve integrated module 1 through the eighth interface 42. At this time, the three-way valves B1-C1 regulate the flow rate, A1 is closed, and then it flows to the third external interface 28 to merge with the refrigerant of the second branch. After merging with the refrigerant of the first branch, it flows out of the control valve integrated module 1 through the fourth external interface 44 and then merges with the refrigerant of the first branch before flowing into the gas-liquid separator. The gas-liquid separator separates the refrigerant and the refrigeration oil, and acts as an intermediate gas storage device to ensure stable gas intake of the drive pump 70. Finally, the refrigerant returns to the drive pump 70, thus forming a cycle.

[0272] See Figure 23 For example, the thermal management system 10 includes a fourth mode in which cooling of the motor assembly and the electronic control assembly can be achieved. In this mode, the eighth throttle valve 100, the first throttle valve 5, the second throttle valve 6, the fourth throttle valve 9, and the fifth throttle valve 11 are open, while the remaining valves are closed.

[0273] The drive pump 70 compresses and discharges high-temperature, high-pressure gas, which flows through the eighth throttle valve 100 and then into the external condenser to release heat and condense into a medium-temperature, high-pressure liquid. After passing through a one-way valve, it flows through the second external interface 32 into the control valve integrated module 1. Then, in the internal flow channel of the first connecting pipe section 241, it is split into two paths through the first connecting port 201. The first path flows into the first throttle valve 5 (at this time, the flow rate is finely adjusted at a low opening). After being throttled by the first throttle valve 5, it expands into a low-temperature, low-pressure gas-liquid mixture, then flows out of the control valve integrated module 1 through the second interface 36, and then flows into the electronically controlled heat exchange module through the pipe 30 to evaporate and absorb heat into a low-temperature, low-pressure gaseous refrigerant. Then, it flows into the integrated module through the sixth interface 40, and after passing through the fifth throttle valve 11, it flows to the third external interface. At port 28; the second flow into the second throttle valve 6 (at this time, the flow rate is finely adjusted at a low opening), after being throttled and expanded into a low-temperature, low-pressure gas-liquid mixture by the second throttle valve 6, then flows out of the control valve integrated module 1 through the third port 35, and flows into the motor heat exchange module through the pipeline 30. After evaporation and heat absorption in the heat exchange module, it forms a low-temperature, low-pressure gaseous refrigerant, then flows into the control valve integrated module 1 through the seventh port 41, and after passing through the fourth throttle valve 9, it merges with the first refrigerant at the third external port 28 and flows out of the control valve integrated module 1, then flows into the gas-liquid separator. The gas-liquid separator separates the refrigerant and the refrigeration oil, and acts as an intermediate storage tank for the refrigerant gas to ensure stable gas intake of the drive pump 70. Finally, the refrigerant returns to the drive pump 70, thus forming a cycle.

[0274] See Figure 24 For example, the thermal management system 10 includes a fifth mode in which heating of the passenger compartment, cooling of the motor components, and cooling of the electronic control components can be achieved. In this mode, the seventh throttle valve 13, the first throttle valve 5, the second throttle valve 6, the fourth throttle valve 9, and the fifth throttle valve 11 are open, while the remaining valves are closed.

[0275] The drive pump 70 compresses and discharges high-temperature, high-pressure gas, which flows into the vehicle's condenser. In the condenser, it releases heat and condenses into a medium-temperature, high-pressure liquid. This liquid then flows through the first interface 37 into the integrated module, and then through the seventh throttle valve 13. The seventh throttle valve 13 is fully open and can act as a flow channel. Inside the first connecting pipe section 241, the liquid splits into two paths via the first connecting port 201. The first path flows into the first throttle valve 5 (at this point, the flow rate is finely adjusted with a low opening). After being throttled by the first throttle valve 5, the liquid expands into a low-temperature, low-pressure gas-liquid mixture, then flows out of the control valve integrated module 1 through the second interface 36. It then flows through pipe 30 into the electronically controlled heat exchange module for evaporation and heat absorption, becoming a low-temperature, low-pressure gaseous refrigerant. Finally, it flows into the integrated module through the sixth interface 40, and after passing through the fifth throttle valve 11, it flows to the... There are three external interfaces at 28. The second flow enters the second throttle valve 6 (at this time, the flow rate is finely adjusted at a low opening). After being throttled by the second throttle valve 6, it expands into a low-temperature, low-pressure gas-liquid mixture and then flows out of the control valve integrated module 1 through the third interface 35. It then flows into the motor heat exchange module through the pipeline 30. After evaporating and absorbing heat in the motor heat exchange module, it forms a low-temperature, low-pressure gaseous refrigerant. It then flows into the control valve integrated module 1 through the seventh interface 41. After passing through the fourth throttle valve 9, it merges with the first refrigerant at the third external interface 28 and flows out of the control valve integrated module 1. It then flows into the gas-liquid separator and is connected to it. The gas-liquid separator separates the refrigerant and the refrigeration oil and acts as an intermediate storage tank for the refrigerant gas to ensure stable gas intake of the drive pump 70. Finally, the refrigerant returns to the drive pump 70, thus forming a cycle.
