Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to an integrated thermal management system for automobiles and an automobile. Background Technology
[0002] With the rapid development of new energy electric vehicles, product iteration is accelerating and competition is becoming increasingly fierce. Vehicle development is constantly pursuing system lightweighting, functional integration, and efficient utilization of engine compartment space. Against this backdrop, the automotive thermal management system, as a core subsystem that simultaneously manages key heat sources such as drive motors and power batteries, as well as the thermal environment of the passenger compartment, not only needs to maintain the heat sources within an efficient and safe temperature range to ensure power performance, suppress thermal runaway, and extend component life, but also needs to provide comfortable temperature, humidity, and air quality for the passenger compartment. Its integrated and lightweight design is of great significance to the integrated and lightweight design of the entire vehicle.
[0003] In the prior art, automotive thermal management systems typically include a thermal management control assembly and a heating, ventilation, and air conditioning (HVAC) assembly. The thermal management control assembly mainly includes a refrigerant flow channel plate and a coolant flow channel plate, used to centrally control the flow direction and flow rate of refrigerant and coolant in each thermal management loop, realizing the distribution and recovery of heat between heat sources such as batteries and motors and the passenger compartment. The HVAC assembly mainly includes a housing and an evaporator and a condenser disposed therein. The evaporator and condenser are respectively provided with refrigerant inlets and outlets, which need to be connected to the refrigerant flow channel plate in the thermal management control assembly through refrigerant pipelines to form a complete refrigerant circulation loop.
[0004] However, in existing technologies, the thermal management control assembly and the HVAC assembly are typically installed as two separate assemblies on the engine compartment side and passenger compartment side of the front bulkhead of the vehicle, respectively. The inlet and outlet of the evaporator and condenser need to be connected to the refrigerant flow channel plate via four refrigerant pipes. These refrigerant pipes are quite long, and due to the dense arrangement of components in the engine compartment, their routing is circuitous and requires detours around multiple vehicle components. This arrangement not only occupies space in the engine compartment and limits the layout and volume of the trunk, but also increases system weight, raises manufacturing costs, and complicates assembly. Furthermore, the lengthy refrigerant pipes are prone to additional heat transfer losses and flow resistance, and introduce multiple potential leak points, thereby reducing the overall energy efficiency and operational reliability of the system. Utility Model Content
[0005] This application provides an integrated thermal management system for automobiles and an automobile, which can effectively free up front engine compartment space, reduce system weight, assembly complexity and manufacturing cost, and improve operational reliability.

By directly integrating a refrigerant flow channel plate, which connects to the evaporator and condenser in the HVAC assembly, into the outer wall of the HVAC assembly housing, the refrigerant inlet and outlet of the evaporator and condenser are connected to the refrigerant flow channel plate. Compared to existing technologies where the refrigerant flow channel plate and evaporator / condenser are respectively installed on the engine compartment side and passenger compartment side of the front bulkhead, requiring four long refrigerant pipes traversing the front bulkhead, this significantly shortens the refrigerant pipe length. It avoids the refrigerant pipes meandering among densely packed components in the front engine compartment, effectively freeing up space and providing greater flexibility for the arrangement of components such as the trunk. Simultaneously, the system weight and assembly complexity are greatly reduced, optimizing manufacturing costs. Furthermore, the shorter pipes reduce heat transfer loss and flow resistance, improving thermal management efficiency. The reduced number of connection points also lowers the risk of leakage, enhancing system reliability.

[0016] Optionally, the thermal management control assembly further includes a gas-liquid separator mounted on the outer wall of the housing.
[0017] In the above solution, by integrating the gas-liquid separator onto the outer wall of the housing, the integration level of the automotive thermal management system can be further improved, thereby further freeing up front engine compartment space and simplifying the assembly process; at the same time, it facilitates coordinated operation with the refrigerant flow channel plate, improving gas-liquid separation efficiency.
[0018] Optionally, a clamping assembly is provided on the outer side wall of the housing, the clamping assembly surrounds the gas-liquid separator and fixes it to the outer side wall of the housing.
[0019] In the above solution, by setting the clamp assembly on the outer wall of the housing and using the clamp assembly to surround the gas-liquid separator and fix it to the outer wall of the housing, the reliable positioning and stable installation of the gas-liquid separator are achieved. At the same time, the vibration and displacement of the gas-liquid separator during vehicle operation are effectively suppressed, and the sealing reliability of the system connection and the durability of the overall structure are enhanced.
[0020] Optionally, it also includes a connection structure, wherein the first connection end and the fifth connection end, the second connection end and the sixth connection end, the third connection end and the seventh connection end, and the fourth connection end and the eighth connection end are respectively detachably connected through the connection structure.
[0021] In the above solution, by setting the connection structure, the first connection end and the fifth connection end, the second connection end and the sixth connection end, the third connection end and the seventh connection end, and the fourth connection end and the eighth connection end can be detachably connected, which not only ensures the reliable sealing of the refrigerant pipeline, but also significantly improves the convenience of assembly and maintenance between the HVAC assembly and the thermal management control assembly, avoiding the maintenance difficulties caused by welding or permanent fixing.
[0022] Optionally, the connection structure includes a first pressure block, a second pressure block, and a bolt assembly;
[0023] The first pressure block is provided with a first through hole, one end of the first through hole extends outward to a first insertion end, and the other end of the first through hole is connected to the fifth connection end or the sixth connection end or the seventh connection end or the eighth connection end.
[0024] The second pressure block is provided with a second through hole adapted to the first insertion end. The first insertion end is inserted from one end of the second through hole, and the other end of the second through hole is connected to the first connection end, the second connection end, the third connection end, or the fourth connection end.
[0025] The bolt assembly presses the first pressure block onto the second pressure block.
[0026] In the above scheme, the first pressure block is provided with a first through hole and a first insertion end extending from one end thereto. The second pressure block is provided with a second through hole adapted to the first insertion end, and the first insertion end is inserted into the second through hole, so that the fifth connection end, the sixth connection end, the seventh connection end or the eighth connection end and the corresponding first connection end, the second connection end, the third connection end or the fourth connection end form a connection channel with accurate alignment and continuous flow. The bolt assembly presses the first pressure block onto the second pressure block to ensure a tight fit at the connection interface, effectively realizing reliable refrigerant flow. This structure is not only easy to assemble, disassemble and maintain, but also has high reliability.
[0027] Optionally, the first pressure block has two first through holes and two first insertion ends that are provided in a one-to-one correspondence, and the second pressure block has two second through holes that are provided in a one-to-one correspondence with the two first insertion ends; the first connecting end, the second connecting end, and the fifth connecting end and the sixth connecting end are detachably connected by one of the connecting structures; the third connecting end, the fourth connecting end, and the seventh connecting end and the eighth connecting end are detachably connected by another connecting structure.
[0028] In the above scheme, by setting two first through holes and two first insertion ends in a one-to-one correspondence on the first pressure block, and setting two second through holes in the second pressure block that correspond one-to-one with the two first insertion ends, a single connection structure can simultaneously realize the integrated connection of two refrigerant channels; wherein, one connection structure detachably connects the first connection end, the second connection end, the fifth connection end, and the sixth connection end simultaneously, and the other connection structure detachably connects the third connection end, the fourth connection end, the seventh connection end, and the eighth connection end simultaneously; this design significantly reduces the number of connecting parts and assembly steps, while enhancing structural compactness, facilitating modular installation and subsequent maintenance, and effectively reducing system leakage risk and manufacturing costs.
[0029] Optionally, the connection structure further includes a sealing ring; a sealing groove is provided circumferentially on the outer side wall of the first insertion end and / or the inner side wall of the second through hole, the sealing ring is embedded in the sealing groove, and when the first insertion end is inserted into the second through hole, the sealing ring is compressed between the outer side wall of the first insertion end and the inner side wall of the second through hole.
[0030] In the above solution, by setting the sealing ring in the connection structure and setting the sealing groove circumferentially on the outer side wall of the first insertion end and / or the inner side wall of the second through hole, the sealing ring is embedded in the sealing groove. When the first insertion end is inserted into the second through hole, the sealing ring is compressed between the outer side wall of the first insertion end and the inner side wall of the second through hole, thereby forming a reliable radial seal, effectively preventing refrigerant leakage under high pressure conditions, improving the sealing performance of the connection interface while taking into account the ease of assembly and disassembly maintainability.
[0031] Secondly, embodiments of this application provide an automobile that includes the aforementioned integrated automotive thermal management system.
[0032] This application proposes an automotive system that integrates a refrigerant flow channel plate, which connects to the evaporator and condenser in the HVAC assembly, directly into the outer wall of the HVAC assembly housing. This allows the refrigerant inlets and outlets of the evaporator and condenser to be connected to the refrigerant flow channel plate in close proximity. Compared to existing technologies where the refrigerant flow channel plate and evaporator / condenser are respectively installed on the engine compartment side and passenger compartment side of the front bulkhead, requiring four long refrigerant pipes traversing the front bulkhead, this significantly shortens the length of the refrigerant pipes. It avoids the refrigerant pipes meandering among densely packed components in the front engine compartment, effectively freeing up space and providing greater flexibility for the arrangement of components such as the front trunk. Simultaneously, the system weight and assembly complexity are greatly reduced, optimizing manufacturing costs. Furthermore, the shorter pipes reduce heat transfer loss and flow resistance, improving thermal management efficiency. The reduced number of connection points also lowers the risk of leakage, enhancing system reliability. Attached Figure Description

[0052] Automotive thermal management systems typically include a thermal management control assembly and a heating, ventilation, and air conditioning (HVAC) assembly. The thermal management control assembly mainly includes a refrigerant flow channel plate and a coolant flow channel plate, used to centrally control the flow direction and flow rate of refrigerant and coolant in each thermal management loop, realizing heat distribution and recovery between heat sources such as the battery and motor and the passenger compartment. The HVAC assembly mainly includes a housing and an evaporator and condenser housed within it. The evaporator and condenser each have refrigerant inlets and outlets, which need to be connected to the refrigerant flow channel plate in the thermal management control assembly via refrigerant piping to form a complete refrigerant circulation loop. However, in the prior art, the thermal management control assembly and the HVAC assembly are usually treated as two independent assemblies, installed on the engine compartment side and passenger compartment side of the front bulkhead of the vehicle, respectively. The inlets and outlets of the evaporator and condenser need to be connected to the refrigerant flow channel plate via four refrigerant pipes. These refrigerant pipes are relatively long, and due to the dense components in the engine compartment, the pipe routing is circuitous and needs to bypass multiple vehicle components. This arrangement not only occupies space in the forward engine compartment and limits the layout and volume of the forward trunk, but also increases system weight, manufacturing costs, and assembly difficulty. In addition, the lengthy refrigerant piping can easily lead to additional heat transfer losses and flow resistance, and introduce multiple potential leak points, thereby reducing the overall energy efficiency and operational reliability of the system.
[0053] In view of this, in order to effectively free up front engine compartment space, reduce system weight, assembly complexity and manufacturing costs, and improve operational reliability, this application provides an integrated automotive thermal management system, including a heating, ventilation and air conditioning assembly 1 and a thermal management control assembly 2, wherein:
[0054] like Figure 1 As shown, the HVAC assembly 1 includes a housing 11, an evaporator 12, and a condenser 13, wherein the evaporator 12 and the condenser 13 are disposed within the housing 11; the evaporator 12 is provided with a first connecting end 121 and a second connecting end 122, one of the first connecting end 121 and the second connecting end 122 being the refrigerant inlet of the evaporator 12, and the other being the refrigerant outlet of the evaporator 12; the condenser 13 is provided with a third connecting end 131 and a fourth connecting end 132, one of the third connecting end 131 and the fourth connecting end 132 being the refrigerant inlet of the condenser 13, and the other being the refrigerant outlet of the condenser 13;
[0055] The thermal management control assembly 2 includes a refrigerant flow channel plate 21, which is mounted on the outer side wall of the housing 11, such as... Figure 2As shown, the refrigerant flow channel plate 21 is provided with a fifth connecting end 211, a sixth connecting end 212, a seventh connecting end 213, and an eighth connecting end 214. The fifth connecting end 211, the sixth connecting end 212, the seventh connecting end 213, and the eighth connecting end 214 are refrigerant outlets or refrigerant inlets on the refrigerant flow channel plate 21 that are connected to the evaporator 12 or the condenser 13. Specifically, the first connecting end 121 is connected to the fifth connecting end 211, the second connecting end 122 is connected to the sixth connecting end 212, the third connecting end 131 is connected to the seventh connecting end 213, and the fourth connecting end 132 is connected to the eighth connecting end 214. The specific connection method can be achieved by directly welding them together, or by using other connecting components, as long as the connection between the two ends can be achieved, there is no limitation here.
[0056] This application proposes an integrated automotive thermal management system. By directly integrating the refrigerant flow channel plate 21, which needs to connect to the evaporator 12 and condenser 13 in the HVAC assembly 1, into the outer wall of the housing 11 of the HVAC assembly 1, the refrigerant inlet and outlet of the evaporator 12 and condenser 13 are connected to the refrigerant flow channel plate 21. Compared with the prior art where the refrigerant flow channel plate 21 and the evaporator 12 and condenser 13 are respectively installed on the engine compartment side and passenger compartment side of the front bulkhead, and need to be connected through four long refrigerant pipes passing through the front bulkhead, the length of the refrigerant pipes is significantly shortened. This avoids the refrigerant pipes detouring among the dense components in the front engine compartment, effectively freeing up space in the front engine compartment and providing greater freedom for the arrangement of components such as the front trunk. At the same time, the system weight and assembly complexity are greatly reduced, and the manufacturing cost is optimized. In addition, shorter piping reduces heat transfer loss and flow resistance, improving thermal management efficiency, and the reduced number of connection points lowers the risk of leakage, thus enhancing the reliability of system operation.
[0057] In other embodiments, such as Figure 3 As shown, at least one mounting part 3 is provided on the outer side wall of the housing 11, and the refrigerant flow channel plate 21 is mounted on the outer side wall of the housing 11 through the mounting part 3. Preferably, in this embodiment, the number of mounting parts 3 is three, and they are triangularly distributed on the outer side wall of the housing 11, resulting in more uniform force distribution and better installation effect. In addition, as one possible implementation, the mounting part 3 can be a boss integrally formed with the housing 11, and the refrigerant flow channel plate 21 is fixed to the outer side wall of the housing 11 by bolts. Of course, other mounting part structures and installation methods are also possible, and no limitation is made here.
[0058] In the above scheme, the refrigerant flow channel plate 21 is installed on the outer side wall of the housing 11 through the mounting part 3, which not only makes the assembly simple and has high stability, but also significantly improves the space utilization efficiency and enhances the structural compactness and operational reliability of the vehicle thermal management system.
[0059] In other embodiments, such as Figure 1 As shown, the thermal management control assembly 2 also includes a heat exchanger 22 for realizing heat exchange between the refrigerant and the coolant, and the heat exchanger 22 is installed on the outer side wall of the housing 11. The installation can be direct or indirect. For example, the heat exchanger 22 can be indirectly installed on the outer side wall of the housing 11 by being installed on the refrigerant flow channel plate 21, or it can be directly installed on the relevant mounting part on the outer side wall of the housing 11. Of course, it can also be directly connected to both the refrigerant flow channel plate 21 and the outer side wall of the housing 11. There is no limitation here.
[0060] In the above scheme, by integrating the heat exchanger 22 onto the outer side wall of the housing 11, the integration level of the automotive thermal management system can be further improved, thereby further freeing up the front engine compartment space, simplifying the assembly process, and facilitating its coordinated operation with the refrigerant flow channel plate 21.
[0061] In other embodiments, the process continues as follows: Figure 1 As shown, the thermal management control assembly 2 also includes a gas-liquid separator 23 for gas-liquid separation of the refrigerant, and the gas-liquid separator 23 is installed on the outer side wall of the housing 11. Similarly, the installation can be direct or indirect. For example, the gas-liquid separator 23 can be indirectly installed on the outer side wall of the housing 11 by installing it on the refrigerant flow channel plate 21, or it can be directly installed on the relevant mounting part on the outer side wall of the housing 11. Of course, it can also be directly connected to both the refrigerant flow channel plate 21 and the outer side wall of the housing 11. There are no restrictions here.
[0062] In the above solution, by integrating the gas-liquid separator 23 onto the outer wall of the housing 11, the integration level of the automotive thermal management system can be further improved, thereby further freeing up the front engine compartment space and simplifying the assembly process; at the same time, it facilitates cooperation with the refrigerant flow channel plate 21 to improve gas-liquid separation efficiency.
[0063] In other embodiments, such as Figure 3 As shown, a clamping assembly 4 is provided on the outer side wall of the housing 11. The clamping assembly 4 surrounds the gas-liquid separator 23 and fixes it to the outer side wall of the housing 11.
[0064] In the above solution, by setting the clamp assembly 4 on the outer wall of the housing 11 and using the clamp assembly 4 to surround the gas-liquid separator 23 and fix it to the outer wall of the housing 11, the reliable positioning and stable installation of the gas-liquid separator 23 are achieved. At the same time, the vibration and displacement of the gas-liquid separator 23 during vehicle operation are effectively suppressed, and the sealing reliability of the system connection and the durability of the overall structure are enhanced.
[0065] In other embodiments, such as Figure 2 As shown, the automotive integrated thermal management system further includes a connection structure 5. The first connection end 121 and the fifth connection end 211 are detachably connected via the connection structure 5. The second connection end 122 and the sixth connection end 212 are detachably connected via the connection structure 5. The third connection end 131 and the seventh connection end 213 are detachably connected via the connection structure 5. The fourth connection end 132 and the eighth connection end 214 are also detachably connected via the connection structure 5. Specifically, the connection structure 5 can be disposed on the outside of the housing 11. The first connection end 121, the second connection end 122, the third connection end 131, and the fourth connection end 132 pass through the side wall of the housing 11 and connect to the... The connection structure 5 can be disposed on the inner side of the housing 11, with the fifth connection end 211, the sixth connection end 212, the seventh connection end 213, and the eighth connection end 214 passing through the side wall of the housing 11 and connected to the corresponding connection structure 5; or, more preferably, as shown in this embodiment, the connection structure 5 can be disposed through the side wall of the housing 11, with one side connected to the first connection end 121, the second connection end 122, the third connection end 131, and the fourth connection end 132 located on the inner side of the housing 11, and the other side connected to the fifth connection end 211, the sixth connection end 212, the seventh connection end 213, and the eighth connection end 214 located on the outer side of the housing 11, without limitation.
[0066] In the above solution, by setting the connection structure 5, the first connection end 121 and the fifth connection end 211, the second connection end 122 and the sixth connection end 212, the third connection end 131 and the seventh connection end 213, and the fourth connection end 132 and the eighth connection end 214 can be detachably connected, which not only ensures the reliable sealing of the refrigerant pipeline, but also significantly improves the convenience of assembly and maintenance between the HVAC assembly 1 and the thermal management control assembly 2, avoiding the maintenance difficulties caused by welding or permanent fixing.
[0067] In other embodiments, such as Figure 4 , Figure 5As shown, the connection structure 5 includes a first pressure block 51, a second pressure block 52, and a bolt assembly 53;
[0068] The first pressure block 51 is provided with a first through hole 511, one end of the first through hole 511 extends outward to a first insertion end 512, and the other end of the first through hole 511 is connected to the fifth connecting end 211 or the sixth connecting end 212 or the seventh connecting end 213 or the eighth connecting end 214.
[0069] The second pressure block 52 is provided with a second through hole 521 adapted to the first insertion end 512. The first insertion end 512 is inserted from one end of the second through hole 521, and the other end of the second through hole 521 is connected to the first connecting end 121 or the second connecting end 122 or the third connecting end 131 or the fourth connecting end 132.
[0070] The bolt assembly 53 presses the first pressure block 51 onto the second pressure block 52.
[0071] In the above scheme, the first pressure block 51 is provided with a first through hole 511 and a first insertion end 512 extending from one end thereto. The second pressure block 52 is provided with a second through hole 521 adapted to the first insertion end 512, and the first insertion end 512 is inserted into the second through hole 521, so that the fifth connecting end 211, the sixth connecting end 212, the seventh connecting end 213 or the eighth connecting end 214 and the corresponding first connecting end 121, the second connecting end 122, the third connecting end 131 or the fourth connecting end 132 form a connection channel with accurate alignment and continuous flow. The bolt assembly 53 presses the first pressure block 51 onto the second pressure block 52 to ensure a tight fit at the connection interface, effectively realizing reliable refrigerant flow. This structure is not only easy to assemble, disassemble and maintain, but also has high reliability.
[0072] In other embodiments, the process continues as follows: Figure 4 , Figure 5 As shown, the first pressing block 51 has two first through holes 511 and two first insertion ends 512 that are provided in a one-to-one correspondence, and the second pressing block 52 has two second through holes 521 that are provided in a one-to-one correspondence with the two first insertion ends 512; the first connecting end 121, the second connecting end 122 and the fifth connecting end 211 and the sixth connecting end 212 are detachably connected by a connecting structure 5; the third connecting end 131, the fourth connecting end 132 and the seventh connecting end 213 and the eighth connecting end 214 are detachably connected by another connecting structure 5.
[0073] In the above scheme, by providing two first through holes 511 and two first insertion ends 512 arranged in a one-to-one correspondence on the first pressure block 51, and providing two second through holes 521 that correspond one-to-one with the two first insertion ends 512 on the second pressure block 52, a single connection structure 5 can simultaneously realize the integrated connection of two refrigerant channels; wherein, one connection structure 5 detachably connects the first connection end 121, the second connection end 122 with the fifth connection end 211 and the sixth connection end 212, and the other connection structure 5 detachably connects the third connection end 131, the fourth connection end 132 with the seventh connection end 213 and the eighth connection end 214; this design significantly reduces the number of connecting parts and assembly steps, while enhancing structural compactness, facilitating modular installation and subsequent maintenance, and effectively reducing system leakage risk and manufacturing costs.
[0074] In other embodiments, such as Figure 5 As shown, the connecting structure 5 also includes a sealing ring 54; as Figure 6 As shown, a sealing groove 513 is provided circumferentially on the outer side wall of the first insertion end 512 and / or the inner side wall of the second through hole 521. The number of sealing grooves 513 can be one or more, which is not limited here. The sealing ring 54 is embedded in the sealing groove 513, and when the first insertion end 512 is inserted into the second through hole 521, the sealing ring 54 is compressed between the outer side wall of the first insertion end 512 and the inner side wall of the second through hole 521 to achieve sealing. Specifically, in this embodiment, in order to simultaneously consider sealing performance, ease of assembly and cost, a scheme of providing two sealing grooves 513 circumferentially on the outer side wall of the first insertion end 512 is adopted. This not only meets the sealing performance requirements, but also makes insertion and assembly more convenient and lowers the cost.
[0075] In the above solution, by setting the sealing ring 54 in the connection structure 5 and setting the sealing groove 513 circumferentially on the outer side wall of the first insertion end 512 and / or the inner side wall of the second through hole 521, the sealing ring 54 is embedded in the sealing groove 513. When the first insertion end 512 is inserted into the second through hole 521, the sealing ring 54 is compressed between the outer side wall of the first insertion end 512 and the inner side wall of the second through hole 521, thereby forming a reliable radial seal, effectively preventing refrigerant leakage under high pressure conditions, improving the sealing performance of the connection interface while taking into account the ease of assembly and disassembly maintainability.
[0076] On the other hand, embodiments of this application provide an automobile that includes the aforementioned integrated automotive thermal management system.
[0077] This application proposes an automobile that integrates the refrigerant flow channel plate 21, which needs to connect to the evaporator 12 and condenser 13 in the HVAC assembly 1, directly into the outer wall of the housing 11 of the HVAC assembly 1. This allows the refrigerant inlet and outlet of the evaporator 12 and condenser 13 to be connected to the refrigerant flow channel plate 21 nearby. Compared with the prior art where the refrigerant flow channel plate 21 and the evaporator 12 and condenser 13 are respectively installed on the engine compartment side and passenger compartment side of the front bulkhead of the automobile, and need to be connected through four long refrigerant pipes passing through the front bulkhead, this significantly shortens the length of the refrigerant pipes, avoids the detour of the refrigerant pipes among the dense components in the front engine compartment, effectively frees up the front engine compartment space, and provides greater freedom for the arrangement of components such as the front trunk. At the same time, the system weight and assembly complexity are greatly reduced, and the manufacturing cost is optimized. In addition, shorter piping reduces heat transfer loss and flow resistance, improving thermal management efficiency, and the reduced number of connection points lowers the risk of leakage, thus enhancing the reliability of system operation.
