This improves the overall aesthetics of the automotive thermal management system and avoids the encroachment of exposed piping on the installation space of surrounding components, resulting in a more compact spatial layout, significantly reduced size, increased integration, and lower risk of refrigerant leakage. Additionally, both the compressor's suction and discharge ports face the refrigerant substrate, allowing the refrigerant to directly enter the substrate after exiting the discharge port, bypassing long flow paths and reducing the number of bends in the flow path, thus lowering flow resistance. The compressor and refrigerant substrate are connected by threaded connections via connecting column units and connector units. This threaded connection is detachable; in case of compressor or refrigerant substrate failure, only the connector unit needs to be disassembled to separate the compressor from the substrate, improving maintenance efficiency.

[0023] This utility model also provides a car that can reduce the installation space occupied inside the car body, adapt to the narrow space inside the engine compartment, eliminate the need for separate expansion of the installation area, and reduce the difficulty of overall vehicle design.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] This embodiment provides an automotive thermal management system that has a high degree of integration, is suitable for placement in different installation environments, improves aesthetics, and reduces the risk of refrigerant leakage.

[0043] like Figures 1-3 As shown, the automotive thermal management system includes a compressor 1, a refrigerant base plate 2, and a condenser 3, a liquid receiver 4, a first electronic expansion valve 5, and an evaporator 6 integrated on the refrigerant base plate 2. The compressor 1 includes an intake port 11 and an exhaust port 12, both facing the refrigerant base plate 2. A refrigerant flow channel is provided within the refrigerant base plate 2, and both the intake port 11 and the exhaust port 12 communicate with the refrigerant flow channel; the exhaust port 12, condenser 3, liquid receiver 4, first electronic expansion valve 5, evaporator 6, and intake port 11 are all connected in series through the refrigerant flow channel to form a refrigerant circulation loop. A connecting post unit protrudes from the compressor 1. The thermal management system also includes a connecting component unit. A mounting hole 21 is provided on the refrigerant base plate 2, and one end of the connecting component unit passes through the mounting hole 21 and is threadedly connected to the connecting post unit.

[0044] Based on the above design, in this embodiment, the condenser 3, liquid receiver 4, first electronic expansion valve 5, and evaporator 6 are all integrated onto the refrigerant substrate 2. The refrigerant flow channels within the refrigerant substrate 2 replace the exposed pipes of traditional technology, concentrating the originally dispersed components onto the refrigerant substrate 2. Furthermore, the refrigerant flow path is hidden inside the refrigerant substrate 2, completely eliminating the complex exposed piping. This significantly improves the aesthetics of the entire automotive thermal management system and avoids the encroachment of exposed piping on the installation space of surrounding components. This makes the automotive thermal management system more compact in terms of spatial layout, greatly reducing its size and improving its integration. It can be flexibly deployed in different installation environments, reducing the risk of refrigerant leakage.

[0045] Furthermore, in this embodiment, both the suction port 11 and the discharge port 12 of the compressor 1 face the refrigerant substrate 2, allowing the refrigerant to directly enter the refrigerant substrate 2 after flowing out of the discharge port 12, without needing to be transported through a long flow channel. This reduces the number of bends in the flow channel, lowers flow resistance, and ensures the refrigerant circulation speed. The compressor 1 and the refrigerant substrate 2 are connected by a connecting column unit and a connecting piece unit via threads. The threaded connection is a detachable structure. When either the compressor 1 or the refrigerant substrate 2 fails, only the connecting piece unit needs to be disassembled to separate the compressor 1 from the refrigerant substrate 2, improving maintenance efficiency.

[0046] In some alternative embodiments, the liquid storage tank 4 can also be replaced by a gas-liquid separator.

[0047] It should be noted that, regarding the specific direction of the refrigerant flow channel inside the refrigerant substrate 2, those skilled in the art can, based on the refrigerant circulation principle, drill or mill a through channel within the refrigerant substrate 2 in the order of "compressor 1 exhaust port 12 → condenser 3 → liquid receiver 4 → first electronic expansion valve 5 → evaporator 6 → compressor 1 suction port 11," using straight lines, right angles, or circular arc transitions. The cross-sectional shape, turning radius, and sealing step size of the refrigerant flow channel can all be selected according to conventional hydraulic pipe diameters and sealing specifications. Therefore, the specification does not provide illustrations or detailed descriptions of the refrigerant flow channel direction within the refrigerant substrate 2, but this does not affect those skilled in the art from implementing this technical solution, nor does it lead to ambiguity regarding the refrigerant flow direction.

[0048] It should be noted that, as Figure 4 As shown, the abbreviations of the components in the automotive thermal management system in this embodiment are as follows:

[0049] Condenser 3 (WCC), liquid receiver 4 (RD), first electronic expansion valve 5 (EXV1), evaporator 6 (Chiller), second electronic expansion valve 9 (EXV2), high pressure charging component 7 (HP Injection), low pressure charging component 8 (LP Injection), first temperature and pressure sensor 111 (PT1), and second temperature and pressure sensor 121 (PT2).

[0050] like Figures 2-3 As shown, the connecting post unit includes a first connecting post 13 and a second connecting post 14. The first connecting post 13 is located at the intake port 11, and the second connecting post 14 is located at the exhaust port 12. The refrigerant substrate 2 includes a first connecting arm 22 and a second connecting arm 23. Both the first connecting arm 22 and the second connecting arm 23 have mounting holes 21. The connecting member unit includes a first connecting member and a second connecting member. One end of the first connecting member passes through the mounting hole 21 on the first connecting arm 22 and connects to the first connecting post 13. One end of the second connecting member passes through the mounting hole 21 on the second connecting arm 23 and connects to the second connecting post 14. It can be understood that both the first connecting arm 22 and the second connecting arm 23 have flow channels for refrigerant flow.

[0051] By aligning the first connecting post 13 with the air intake 11 and the second connecting post 14 with the exhaust 12, and by having the first connecting arm 22 correspond one-to-one with the first connecting post 13 and the second connecting arm 23 correspond one-to-one with the second connecting post 14, the positioning of the first connecting arm 22 with the first connecting post 13 and the second connecting arm 23 with the second connecting post 14 during assembly avoids rework due to positioning deviation and improves assembly accuracy.

[0052] Vibration during compressor 1 operation can easily cause unilateral stress on refrigerant substrate 2, which can lead to loosening of connections and failure of the seal at the refrigerant flow channel joint after long-term use. In this embodiment, the first connecting post 13 and the second connecting post 14 cooperate with the first connecting arm 22 and the second connecting arm 23 respectively, so that the connection points between refrigerant substrate 2 and compressor 1 are distributed as symmetrically as possible. This ensures that refrigerant substrate 2 is subjected to balanced forces when compressor 1 vibrates, reduces local stress concentration, avoids loosening of the connection structure, and extends service life.

[0053] Furthermore, both the first connecting post 13 and the second connecting post 14 are provided with internal threads, and both the first connecting member and the second connecting member are provided with external threads. The first connecting member is threadedly connected to the first connecting post 13, and the second connecting member is threadedly connected to the second connecting post 14. This not only improves the reliability of the connection, but also facilitates disassembly and maintenance.

[0054] For example, both the first connector and the second connector can be configured as bolts.

[0055] In some optional embodiments, sealing rings are provided at the connection points between the air intake 11 and the exhaust port 12 and the refrigerant flow channel. The sealing rings can compensate for the machining errors of the mating surfaces of the refrigerant base plate 2 and the compressor 1, effectively preventing refrigerant from leaking from the refrigerant flow channel connection points, thereby improving the sealing performance.

[0056] Alternatively, the sealing ring can be made of hydrogenated nitrile rubber.

[0057] Furthermore, the refrigerant substrate 2 has a positioning groove (not shown in the figure) coaxial with the exhaust port 12 and the suction port 11 on the side facing the compressor 1. A sealing ring is embedded in the positioning groove. The positioning groove limits the sealing ring, preventing the sealing ring from being misaligned and ensuring sealing reliability.

[0058] like Figure 3 As shown, the refrigerant substrate 2 also includes a first connecting portion 24 and a second connecting portion 25. One end of the first connecting portion 24 is connected to the first connecting arm 22, and the other end is connected to the evaporator 6. One end of the second connecting portion 25 is connected to the second connecting arm 23, and the other end is connected to the condenser 3. By connecting the evaporator 6 and the condenser 3 to the refrigerant substrate 2 through the first connecting portion 24 and the second connecting portion 25, the evaporator 6 and the condenser 3 are symmetrically arranged on the refrigerant substrate 2, which avoids the center of gravity of the automotive thermal management system from shifting and improves stability.

[0059] For example, one end of the first connecting part 24 is bolted to the first connecting arm 22, and the other end is welded to the evaporator 6; one end of the second connecting part 25 is bolted to the second connecting arm 23, and the other end is welded to the condenser 3. It can be understood that both the first connecting part 24 and the second connecting part 25 are provided with flow channels for refrigerant circulation.

[0060] Furthermore, the refrigerant substrate 2 also includes a third connecting portion 26, which is disposed between the first connecting portion 24 and the second connecting portion 25. One end of the third connecting portion 26 is connected to the first connecting portion 24, and the other end is connected to the second connecting portion 25. The side of the third connecting portion 26 away from the compressor 1 is connected to the liquid receiver 4. In addition, the integrally molded structure of the third connecting portion 26 enhances the overall rigidity of the refrigerant substrate 2, further improving the vibration resistance of the automotive thermal management system and adapting to the bumpy environment of a vehicle.

[0061] In some optional embodiments, the first connecting portion 24 and the second connecting portion 25 are both strip-shaped protrusions extending from the refrigerant substrate 2. Both the first connecting portion 24 and the second connecting portion 25 have extended flow channels that communicate with the main flow channel within the refrigerant substrate 2, the refrigerant interface of the evaporator 6, and the condenser 3. One end of the first connecting portion 24 is connected to the first connecting arm 22 via an arc transition, and the other end is connected to the refrigerant interface of the evaporator 6 via laser welding. One end of the second connecting portion 25 is connected to the second connecting arm 23 via an arc transition, and the other end is connected to the refrigerant interface of the condenser 3 via laser welding.

[0062] In some optional embodiments, the third connecting part 26 is a rectangular plate structure, which is integrally formed with the first connecting part 24 and the second connecting part 25 by die casting, and a circular mounting platform is provided on the side of the third connecting part 26 away from the compressor 1, and the liquid storage tank 4 is fixed to the circular mounting platform by laser welding.

[0063] It is understandable that the first connecting part 24, the second connecting part 25 and the third connecting part 26 are all provided with flow channels for refrigerant flow.

[0064] like Figure 3 As shown, the automotive thermal management system also includes a high-pressure charging component 7 and a low-pressure charging component 8. The high-pressure charging component 7 is disposed on the first connecting arm 22, and one end of the high-pressure charging component 7 is connected to the liquid storage tank 4, and the other end is connected to the first electronic expansion valve 5. The low-pressure charging component 8 is disposed on the second connecting arm 23, and one end of the low-pressure charging component 8 is connected to the evaporator 6, and the other end is connected to the suction port 11 of the compressor 1.

[0065] The first connecting arm 22 and the second connecting arm 23 are respectively equipped with a high-pressure charging component 7 and a low-pressure charging component 8. Refrigerant charging, recovery, and pressure testing can be completed directly through the high-pressure charging component 7 and the low-pressure charging component 8 without disassembling any parts, simplifying maintenance operations and improving maintenance efficiency. The high-pressure charging component 7 is adapted to the high-pressure refrigerant on the condenser 3 side, and the low-pressure charging component 8 is adapted to the low-pressure refrigerant on the evaporator 6 side. This classification arrangement avoids component damage caused by incorrect connection of pressure interfaces during charging.

[0066] For example, both the high-pressure charging component 7 and the low-pressure charging component 8 are selected from automotive standard refrigerant charging valves.

[0067] like Figure 4 As shown, the automotive thermal management system also includes a second electronic expansion valve 9. One end of the second electronic expansion valve 9 is connected to the refrigerant flow channel between the low-pressure charging component 8 and the evaporator 6, and the other end of the second electronic expansion valve 9 is connected to the exhaust port 12 of the compressor 1 to form a hot gas bypass circuit; and the second electronic expansion valve 9 is integrated on the refrigerant substrate 2.

[0068] A hot gas bypass circuit is formed by the second electronic expansion valve 9. When the ambient temperature is low, the second electronic expansion valve 9 opens to introduce the high-temperature refrigerant from the exhaust port 12 of the compressor 1 into the low-pressure side flow channel, where it mixes with the unevaporated liquid refrigerant on the low-pressure side, raising the refrigerant temperature and preventing liquid refrigerant from entering the compressor 1. This protects the compressor 1 from liquid slugging damage, improves safety, and extends the service life of the compressor 1.

[0069] Optionally, both the first electronic expansion valve 5 and the second electronic expansion valve 9 are pulse-type electromagnetic expansion valves.

[0070] like Figure 4 As shown, the automotive thermal management system in this embodiment also includes a first temperature and pressure sensor 111 and a second temperature and pressure sensor 121. Both the first temperature and pressure sensor 111 and the second temperature and pressure sensor 121 are disposed on the refrigerant substrate 2. The first temperature and pressure sensor 111 is connected to the suction port 11 of the compressor 1 to measure the temperature and pressure of the refrigerant at the suction port 11, and the second temperature and pressure sensor 121 is connected to the exhaust port 12 of the compressor 1 to measure the temperature and pressure of the refrigerant at the exhaust port 12.

[0071] For example, the first temperature and pressure sensor 111 and the second temperature and pressure sensor 121 in this embodiment can both be set to the types of piezoresistive temperature and pressure integrated sensors commonly found on the market.

[0072] In this embodiment, by integrating the first temperature and pressure sensor 111, the second temperature and pressure sensor 121, the first electronic expansion valve 5 and the second electronic expansion valve 9, the high-pressure charging component 7 and the low-pressure charging component 8 onto the refrigerant substrate 2, the size of the automotive thermal management system is reduced, installation space is saved, and integration is improved.

[0073] This embodiment also provides an automobile, which includes a vehicle body and the aforementioned automobile thermal management system, wherein the automobile thermal management system is fixed in a preset installation area of ​​the vehicle body; the preset installation area is the interior of the engine compartment of the vehicle body.

[0074] Because the vehicle has the aforementioned thermal management system, it can reduce the space occupied by the installation inside the vehicle body, adapt to the small space inside the engine compartment, eliminate the need for separate expansion of the installation area, and reduce the difficulty of overall vehicle design.
