The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as a limitation on the utility model.

[0036] As Figures 1 to 6As shown, the embodiment provides a vehicle thermal management system, which comprises a compressor 1, a controller 2 and a heater 3, the compressor 1 and the heater 3 are respectively arranged on two sides of the controller 2 and are electrically connected with the controller 2, and the vehicle thermal management system further comprises: an extension structure 4 arranged on the compressor 1, the extension structure 4 has a refrigerant flow path 45 and a first connecting port 41, a second connecting port 42 and a third connecting port 43 communicated with the refrigerant flow path 45, and the third connecting port 43 is located between the first connecting port 41 and the second connecting port 42; a condenser 5 arranged on the extension structure 4, and the condenser 5 is internally provided with a condensing flow path, one end of the condensing flow path is communicated with an exhaust port 15 of the compressor 1, and the other end is communicated with the first connecting port 41; and an evaporator 6 arranged on the extension structure 4, and the evaporator 6 is internally provided with an evaporating flow path, one end of the evaporating flow path is communicated with a suction port 16 of the compressor 1, and the other end is communicated with the second connecting port 42, and an expansion valve 71 is communicated with the refrigerant flow path 45 through the third connecting port 43.

[0037] The vehicle thermal management system adopts the extension structure 4 arranged on the compressor 1, the extension structure 4 has the refrigerant flow path 45 and the first connecting port 41 and the second connecting port 42 communicated with the refrigerant flow path 45, the condenser 5 and the evaporator 6 are arranged on the extension structure 4, one end of the condensing flow path is communicated with the exhaust port 15 of the compressor 1, and the other end is communicated with the first connecting port 41, one end of the evaporating flow path is communicated with the suction port 16 of the compressor 1, and the other end is communicated with the second connecting port 42, so that the arrangement of the integrated flow channel plate in the prior art can be omitted, the production cost is reduced, the system volume and weight are reduced, the interface design at the connection position of the compressor and the flow channel plate in the prior art can be omitted, and the refrigerant leakage amount is further reduced. The vehicle thermal management system has the advantages of compact structure, small occupied volume, simple and convenient installation, and effectively solves the problems of large volume, being not conducive to vehicle arrangement and complex installation of the vehicle thermal management system in the prior art.

[0038] Meanwhile, in order to throttle and depressurize the refrigerant in the refrigerant flow path 45, the expansion valve 71 is communicated with the refrigerant flow path 45 through the third connecting port 43, so that the expansion valve 71 can throttle and depressurize the refrigerant flowing from the condenser 5 to the evaporator 6.

[0039] In some embodiments, as shown in Figure 1 and Figure 2 the compressor 1 comprises a shell 11, wherein the extension structure 4 is arranged on the shell 11, and the refrigerant flow path 45 extends along the length direction of the shell 11, so that the refrigerant flow path 45 is conveniently arranged and the condenser 5 and the evaporator 6 can also be conveniently communicated.

[0040] Optionally, the extension structure 4 has a mating surface whose shape matches the shape of the outer shell 11, which facilitates the connection between the extension structure 4 and the outer shell 11; at the same time, the extension structure 4 also has a mounting surface, which is a plane, so that the condenser 5 and the evaporator 6 can be mounted on the mounting surface, wherein the first connection port 41 and the second connection port 42 are both mounted on the mounting surface.

[0041] Optionally, the outer shell 11 and the extension structure 4 are integrated into one piece, which facilitates processing and reduces costs.

[0042] Furthermore, the high-temperature gaseous refrigerant enters the condenser 5 through the exhaust port 15 and exchanges heat with the water passage inside the condenser 5, cooling down to liquid refrigerant which then enters the refrigerant flow path 45 through the first connection port 41. The condenser 5 is equipped with a water passage, with its two ends connected to the condenser inlet 51 and the condenser outlet 52, respectively. The water passage absorbs heat from the refrigerant within the condenser 5 to raise its temperature. The condenser 5 is fixed to the extension structure 4 by bolts or welding.

[0043] In this system, the liquid refrigerant, cooled by the condenser 5, enters the refrigerant flow path 45 through the first connection port 41. The compressor 1 has a low-pressure chamber 18. After being throttled and depressurized by the expansion valve 71, it enters the evaporator 6 through the second connection port 42. Furthermore, the two ends of the evaporation flow path are connected to the suction port 16 and the second connection port 42, respectively. In the refrigerant flow path 45, the low-pressure two-phase refrigerant, passing through the expansion valve 71, enters the evaporator 6 through the second connection port 42 to exchange heat with the water passage inside the evaporator 6. After absorbing heat, it becomes a low-temperature gaseous refrigerant and enters the low-pressure chamber 18 of the compressor 1 through the suction port 16. The evaporator 6 has a water passage, with its two ends connected to the evaporator inlet 61 and the evaporator outlet 62, respectively. The water passage releases heat to the refrigerant within the evaporator 6 to cool it down. The evaporator 6 is fixed to the extension structure 4 by bolts or welding.

[0044] Optionally, the vehicle thermal management system also includes an expansion valve connector that can be electrically connected to the controller 2.

[0045] Specifically, the vehicle thermal management system also includes a sealing head 72, and the end of the extension structure 4 has an opening 44 communicating with the refrigerant flow path 45. The opening 44 can be sealed by the sealing head 72.

[0046] In this embodiment, as Figures 1 to 4As shown, the compressor 1 also includes a scroll assembly 12, a drive assembly 13, and a filter element 14 disposed within the housing 11. The scroll assembly 12 has an oil return hole 121 communicating with the exhaust port 15. The filter element 14 is disposed on the scroll assembly 12 and covers the oil return hole 121. This arrangement allows the liquid stored in the low-pressure chamber 18 of the compressor 1 to function as a gas-liquid separator, replacing the traditional external gas-liquid separator, further saving component costs and reducing the size and weight of the integrated module. The filter element 14 includes, but is not limited to, filter screens and filter plates.

[0047] Specifically, the drive component 13 is connected to the scroll plate assembly 12, and the drive component 13 can drive the scroll plate assembly 12 to rotate.

[0048] Furthermore, the scroll plate assembly 12 includes an intermediate body 122, a stationary plate 123, and a moving plate 124. The intermediate body 122 and the stationary plate 123 are both mounted on the outer casing 11, abutting against each other. The moving plate 124 is located between the intermediate body 122 and the stationary plate 123, and a compression chamber 125 is provided between the moving plate 124 and the stationary plate 123. The intermediate body 122 has an oil return hole 121, which communicates with the exhaust port 15 through the compression chamber 125. The filter element 14 is mounted on the intermediate body 122 to cover the oil return hole 121, ensuring effective filtration. The drive assembly 13 is connected to the moving plate 124 to drive its rotation.

[0049] Optionally, the compressor 1 also includes a housing 11 and a rear cover 17 connected to the housing 11, with the exhaust port 15 disposed on the housing 11 or the rear cover 17.

[0050] Optionally, the intermediate body 122 and the stationary disk 123 are both located inside the outer casing 11 and connected to the inner wall of the outer casing 11; or, as Figure 3 As shown, one end of the intermediate body 122 is connected to the outer shell 11, and the other end is connected to one end of the static disk 123, the other end of which is connected to the rear cover 17.

[0051] Specifically, the intermediate body 122 has multiple suction holes 1221, which are located on the side of the outer casing 11 facing away from the ground on the horizontal plane at the center. It should be noted that this invention omits an external gas-liquid separator, instead storing liquid at the bottom of the low-pressure chamber 18 inside the outer casing 11. Through the suction holes 1221, lubricating oil and liquid refrigerant are drawn into the low-pressure chamber 18 of the compressor 1 and stored at its bottom. The high position of the suction holes 1221 allows only gaseous refrigerant to be drawn in, avoiding liquid slugging caused by the intake of liquid refrigerant.

[0052] The oil return holes 121 can be multiple, and the filter element 14 can cover multiple oil return holes 121; or, there can also be multiple filter elements 14, with each oil return hole 121 and filter element 14 corresponding to the other. This allows the number of oil return holes 121 and filter elements 14 to be designed according to actual needs to meet the required design specifications.

[0053] A low-pressure chamber 18 is formed between the intermediate body 122 and the outer shell 11. The stationary plate 123 has an exhaust port 191. An exhaust chamber 192 is formed between the stationary plate 123 and the rear cover 17, which communicates with the exhaust port 191. The exhaust port 191 communicates with the compression chamber 125.

[0054] In addition, the liquid at the bottom of the low-pressure chamber 18 includes liquid refrigerant and lubricating oil, which separate into layers at low temperatures, with the lubricating oil on top and the liquid refrigerant on the bottom. By adjusting the position of the oil return hole 121, the lubricating oil can pass through the oil return hole 121 and the filter element 14 to filter impurities before entering the compression chamber 125 to lubricate the scroll moving parts and ensure the reliability of the compressor 1. The number of oil return holes 121 is not limited. By limiting the position of the suction hole 1221 above the center horizontal plane of the outer casing 11, opening the oil return hole 121, and setting the filter element 14, this utility model allows the low-pressure chamber 18 of the compressor 1 to act as a liquid storage section instead of a gas-liquid separator, saving component costs and reducing the size and weight of the integrated module.

[0055] Optionally, the drive assembly 13 includes a motor 131, a rotor 132, and a rotating shaft 133 disposed within the housing 11. The motor 131 is electrically connected to the controller 2. The rotor 132 is sleeved on the rotating shaft 133. The rotating shaft 133 passes through the intermediate body 122 and is connected to the moving disk 124. The motor 131 drives the rotor 132 to rotate, the rotor 132 drives the rotating shaft 133 to rotate, and the rotating shaft 133 drives the moving disk 124 to rotate.

[0056] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the vehicle thermal management system also includes a seal 73. The heater 3 includes a water channel housing 31, a heating element 32, and an electrical connector 33. The water channel housing 31 is mounted on the controller 2 and has a water storage chamber 311 and a receiving chamber 312. The heating element 32 is disposed within the water channel housing 31 and seals the opening 44 of the water storage chamber 311. At least a portion of the electrical connector 33 is disposed within the receiving chamber 312 and can connect the heating element 32 to the controller 2. In this embodiment, the seal 73 is disposed on the electrical connector 33 and can seal the gap between the receiving chamber 312 and the electrical connector 33, thereby ensuring that water in the water storage chamber 311 does not enter the controller 2 through the receiving chamber 312, thus ensuring the safety of the vehicle thermal management system.

[0057] Optionally, the heater 3 also includes a bottom cover 34 connected to the water passage housing 31.

[0058] Optionally, in order to fix the seal 73, the electrical connector 33 has an insulating housing with a groove, and the seal 73 is placed in the groove. This achieves the purpose of fixing the seal 73 to the electrical connector 33, ensuring the stability of the seal 73 during use and preventing the seal 73 from falling off.

[0059] Meanwhile, the electrical connector 33 also includes a pin 331, which is surrounded by an insulating shell 332 and sealed to the pin 331 via a sealing structure. This sealing structure can be a sealing ring or sealant. Specifically, if the seal 73 fails and a water leak occurs, the fluid medium will leak into the controller 2 through the gap between the electrical connector 33 and the water shell 31, causing equipment damage. Furthermore, the electrical connector 33 is an insulating shell 332 injection-molded around the pin 331. Due to the different thermal expansion coefficients of the two materials, a gap will also occur between the insulating shell 332 and the pin 331, causing leakage or water vapor. Therefore, a sealing structure is provided to seal the insulating shell 332 and the pin 331, further improving the sealing effect.

[0060] The sealing element 73 can be configured in multiple ways as needed. The sealing element 73 includes, but is not limited to, O-rings or lip rings.

[0061] Furthermore, to further ensure that water in the water storage cavity 311 does not flow into the receiving cavity 312, the vehicle thermal management system also includes a sealing ring 74. The sealing ring 74 is disposed on the inner wall of the water channel housing 31 and surrounds the water storage cavity 311, sealing the gap between the water storage cavity 311 and the heating element 32. This further ensures the sealing effect between the water storage cavity 311 and the heating element 32.

[0062] Optionally, the controller 2 is provided with a low-voltage connector 21, a high-voltage connector 22, and a compressor connector 23, wherein the compressor connector 23 can be electrically connected to the motor 131.

[0063] This embodiment also provides a vehicle including the vehicle thermal management system described above. The vehicle using this invention has an extension structure 4 on the compressor 1. The extension structure 4 has a refrigerant flow path 45 and a first connection port 41, a second connection port 42, and a third connection port 43 connected to the refrigerant flow path 45. The condenser 5, evaporator 6, and expansion valve 71 are all mounted on the extension structure 4. One end of the condenser flow path is connected to the exhaust port 15 of the compressor 1, and the other end is connected to the first connection port 41. Similarly, one end of the evaporator flow path is connected to the suction port 16 of the compressor 1, and the other end is connected to the second connection port 42. The expansion valve 71 is connected to the refrigerant flow path 45 through the third connection port 43. This configuration eliminates the need for the integrated flow channel plate found in the prior art, reducing production costs, system size and weight. Furthermore, it eliminates the need for the interface design at the connection between the compressor and the flow channel plate in the prior art, further reducing refrigerant leakage. The vehicle using this utility model has a compact structure, occupies little space, and is simple and convenient to install, effectively solving the problems of existing vehicle thermal management systems that are large in size, inconvenient for overall vehicle layout, and complex to install.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
