[0036] Such as Figures 1 to 6As shown in the figure, this embodiment provides a vehicle thermal management system. The vehicle thermal management system includes a compressor 1, a controller 2, and a heater 3. The compressor 1 and the heater 3 are respectively arranged on both sides of the controller 2 and are both electrically connected to the controller 2. The vehicle thermal management system further includes: An extension structure 4 is arranged 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 that communicate with the refrigerant flow path 45.

The expansion valve 71 is communicated with the refrigerant flow path 45 through the third connection port 43.

[0037] With the vehicle thermal management system of the present invention, an extension structure 4 is arranged on the compressor 1. The extension structure 4 has a refrigerant flow path 45 and a first connection port 41 and a second connection port 42 that communicate with the refrigerant flow path 45. At the same time, both the condenser 5 and the evaporator 6 are arranged on the extension structure 4, and one end of the condensation flow path is communicated with the exhaust port 15 of the compressor 1, and the other end is communicated with the first connection port 41. Similarly, one end of the evaporation flow path is communicated with the suction port 16 of the compressor 1, and the other end is communicated with the second connection port 42. With such an arrangement, the layout 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, and the interface design at the connection between the compressor and the flow channel plate in the prior art can be omitted, further reducing the refrigerant leakage amount. Using the vehicle thermal management system of the present invention, the structure is compact, the occupied volume is small, the installation is simple and convenient, effectively solving the problems that the vehicle thermal management system in the prior art has a large volume, is not conducive to the overall vehicle layout, and has a complex installation.

[0038] At the same time, 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 connection 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 Figure 1 and Figure 2 shown, the compressor 1 includes a housing 11. Among them, the extension structure 4 is arranged on the housing 11, and the refrigerant flow path 45 extends along the length direction of the housing 11, which is convenient for arranging the refrigerant flow path 45 and is also convenient for communicating the condenser 5 and the evaporator 6.

[0040] Optionally, the extension structure 4 has a fitting surface whose shape matches that of the housing 11, which facilitates the connection between the extension structure 4 and the housing 11. At the same time, the extension structure 4 also has a mounting surface which is a flat surface, facilitating the arrangement of both the condenser 5 and the evaporator 6 on the mounting surface. Among them, both the first connection port 41 and the second connection port 42 are arranged on the mounting surface.

[0041] Optionally, the housing 11 and the extension structure 4 are an integral structure, which is convenient for processing and reduces costs.

[0042] Further, the high-temperature gaseous refrigerant enters the condenser 5 through the exhaust port 15 and exchanges heat with the internal water circuit of the condenser 5. After being cooled to a liquid refrigerant, it enters the refrigerant flow path 45 through the first connection port 41. A water circuit is provided inside the condenser 5, and the two ends of the water circuit are respectively connected to the condenser water inlet 51 and the condenser water outlet 52. The water circuit absorbs the heat of the refrigerant inside the condenser 5 to increase the temperature. The condenser 5 is fixed to the extension structure 4 by means of bolts or welding.

[0043] Among them, 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. Further, the two ends of the evaporation flow path are respectively communicated with the suction port 16 and the second connection port 42. 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 and exchanges heat with the internal water circuit of 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. A water circuit is provided inside the evaporator 6, and the two ends of the water circuit are respectively connected to the evaporator water inlet 61 and the evaporator water outlet 62. The water circuit releases heat to the refrigerant inside the evaporator 6 to lower the temperature. The evaporator 6 is fixed to the extension structure 4 by means of bolts or welding.

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

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

[0046] In this embodiment, as Figures 1 to 4As shown in the figure, the compressor 1 further includes a scroll disk assembly 12, a drive assembly 13, and a filter element 14 disposed within the outer casing 11. Among them, the scroll disk assembly 12 has an oil return hole 121 communicating with the exhaust port 15. The filter element 14 is disposed on the scroll disk assembly 12 and covers the oil return hole 121. With this arrangement, the low-pressure chamber 18 of the compressor 1 can be used to store liquid, functioning as a gas-liquid separator, replacing the traditional external gas-liquid separator, further saving component costs and reducing the volume and weight of the integrated module. Among them, the filter element 14 includes, but is not limited to, a filter mesh, a filter plate, etc.

[0047] Specifically, the drive assembly 13 is drivingly connected to the scroll disk assembly 12, and the drive assembly 13 can be used to drive the scroll disk assembly 12 to rotate.

[0048] Furthermore, the scroll disk assembly 12 includes an intermediate body 122, a stationary disk 123, and a moving disk 124. Among them, the intermediate body 122 and the stationary disk 123 are both disposed on the outer casing 11, the intermediate body 122 and the stationary disk 123 are in contact, the moving disk 124 is located between the intermediate body 122 and the stationary disk 123, a compression chamber 125 is formed between the moving disk 124 and the stationary disk 123, the intermediate body 122 has an oil return hole 121, and the oil return hole 121 communicates with the exhaust port 15 through the compression chamber 125. The filter element 14 is disposed on the intermediate body 122 to facilitate covering the oil return hole 121 and ensure the filtering effect. Among them, the drive assembly 13 is drivingly connected to the moving disk 124 to drive the moving disk 124 to rotate.

[0049] Optionally, the compressor 1 further includes a rear cover 17 connected to the outer casing 11, and the exhaust port 15 is disposed on the outer casing 11 or the rear cover 17.

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

[0051] Specifically, the intermediate body 122 is provided with a plurality of suction holes 1221, and the suction holes 1221 are located on the side of the central horizontal plane of the outer casing 11 away from the ground. It should be noted that in the present invention, the external gas-liquid separator is omitted, and the liquid is stored at the bottom of the space of the low-pressure chamber 18 inside the outer casing 11. Through the arrangement of the suction holes 1221, the lubricating oil and the liquid refrigerant are inhaled into the low-pressure chamber 18 of the compressor 1 and stored at its bottom. The position of the suction holes 1221 is relatively high, only inhaling the gaseous refrigerant, avoiding liquid slugging caused by inhaling the liquid refrigerant.

[0052] Among them, there are multiple oil return holes 121, and the filter element 14 can cover multiple oil return holes 121; alternatively, there are also multiple filter elements 14, and the multiple oil return holes 121 and the multiple filter elements 14 are arranged in one-to-one correspondence. In this way, the number of oil return holes 121 and filter elements 14 can be designed according to actual needs to meet the required design requirements.

[0053] Among them, a low-pressure chamber 18 is formed between the intermediate body 122 and the housing 11. The static disk 123 has an exhaust hole 191. An exhaust chamber 192 communicating with the exhaust hole 191 is formed between the static disk 123 and the rear cover 17, and the exhaust hole 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. The two are stratified at low temperatures, with the lubricating oil on the upper side and the liquid refrigerant on the lower side. By adjusting the position of the oil return hole 121, the lubricating oil can enter the compression chamber 125 after passing through the oil return hole 121 and the filter element 14 to filter impurities, lubricate the scroll moving parts, and ensure the reliability of the compressor 1. The number of oil return holes 121 is not limited. Through the above-mentioned method of defining the position of the suction hole 1221 above the central horizontal plane of the housing 11, opening the oil return hole 121 and arranging the filter element 14, the low-pressure chamber 18 of the compressor 1 serves as a liquid storage part to replace the function of the gas-liquid separator, saving component costs and reducing the volume 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 inside 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] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, the vehicle thermal management system further includes a seal 73. Among them, the heater 3 includes a waterway housing 31, a heating element 32, and an electrical connector 33. The waterway housing 31 is disposed on the controller 2, and the waterway housing 31 has a water storage chamber 311 and a receiving chamber 312. The heating element 32 is disposed inside the waterway housing 31 and seals the opening 44 of the water storage chamber 311. At the same time, at least part of the electrical connector 33 is disposed inside the receiving chamber 312 and can connect the heating element 32 and 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 the water in the water storage chamber 311 will 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 further includes a bottom cover plate 34 connected to the waterway housing 31.

[0058] Optionally, in order to fix the seal 73, the electrical connector 33 has an insulating housing provided with a groove, and the seal 73 is arranged in the groove, so as to achieve the purpose of fixing the seal 73 on 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 further includes a plug pin 331, the insulating housing 332 wraps the plug pin 331, and is hermetically connected to the plug pin 331 through a sealing structure, where the sealing structure can be an O-ring or sealant, etc. Specifically, once the seal 73 fails and the waterway leaks, the fluid medium will leak into the controller 2 through the gap at the penetration connection between the electrical connector 33 and the waterway housing 31, causing equipment damage. At the same time, the electrical connector 33 is an insulating housing 332 injection-molded around the plug pin 331. Due to the different thermal expansion coefficients of the two materials, a gap will also be generated between the insulating housing 332 and the plug pin 331, resulting in the leakage and movement of the fluid medium or water vapor. Therefore, a sealing structure is provided to seal the insulating housing 332 and the plug pin 331, further improving the sealing effect.

[0060] Among them, multiple seals 73 can be provided according to actual needs. The seal 73 includes but is not limited to an O-ring or a lip seal.

[0061] Furthermore, in order to further ensure that the water in the water storage cavity 311 does not flow into the accommodation cavity 312, the thermal management system further includes a sealing ring 74 arranged on the inner wall of the waterway housing 31 and surrounding the water storage cavity 311. The sealing ring 74 seals 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, where 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 in the above solution. In the vehicle adopting the present invention, an extension structure 4 is provided 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 communicating with the refrigerant flow path 45. At the same time, the condenser 5, the evaporator 6 and the expansion valve 71 are all arranged on the extension structure 4. And one end of the condensation flow path is communicated with the exhaust port 15 of the compressor 1, and the other end is communicated with the first connection port 41. Similarly, one end of the evaporation flow path is communicated with the suction port 16 of the compressor 1, and the other end is communicated with the second connection port 42. The expansion valve 71 is communicated with the refrigerant flow path 45 through the third connection port 43. With such a setting, the layout 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, and the interface design at the connection between the compressor and the flow channel plate in the prior art can be omitted, further reducing the refrigerant leakage. Using the vehicle of the present invention, the structure is compact, the occupied volume is small, the installation is simple and convenient, effectively solving the problems that the vehicle thermal management system in the prior art has a large volume, is not conducive to the overall vehicle layout and is complicated to install.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
