[0041] The compressor 10 , the thermal management device, and the vehicle according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Reference Figures 1-6 As shown, the compressor 10 according to an embodiment of the present invention includes: a shell 1, a compression component 2, a drive component and a heating component 4, the shell 1 has an installation space 141, an intake flow channel 142 and an exhaust flow channel 143, the compression component 2 is arranged in the installation space 141, and the installation space 141 forms a connecting cavity 1411 in the area outside the compression component 2, the compression component 2 has a compression chamber 21, the inlet of the compression chamber 21 is connected to the intake flow channel 142 through the connecting cavity 1411, and the outlet of the compression chamber 21 is connected to the exhaust flow channel 143, the drive component is arranged in the connecting cavity 1411, the drive component is connected to the compression component 2 in transmission, at least part of the heating component 4 is arranged in the connecting cavity 1411, and the heating component 4 is used to heat the refrigerant in the connecting cavity 1411.

[0043] Among them, the shell 1 is the outer shell of the compressor 10, and the shell 1 defines an installation space 141 and an intake flow channel 142 and an exhaust flow channel 143 connected to the installation space 141. The installation space 141 can be used to install the compression component 2 and the drive component of the compressor 10. The refrigerant can enter the installation space 141 through the intake flow channel 142, and then be pressurized by the compression component 2 and flow out through the exhaust flow channel 143.

[0044] The compression component 2 is arranged in the installation space 141 of the shell 1, and the installation space 141 forms a connecting chamber 1411 in the area outside the compression component 2. The driving component is arranged in the connecting chamber 1411. The driving component is transmission-connected to the compression component 2. The driving component can drive the compression component 2 to work, so that the compression chamber 21 sucks in and increases the pressure of the refrigerant, and then discharges the pressurized refrigerant to the exhaust flow channel 143. That is to say, the inlet of the compression chamber 21 is connected with the intake flow channel 142 through the connecting chamber 1411, and the outlet of the compression chamber 21 is connected with the exhaust flow channel 143. The flow path of the refrigerant in the compressor 10 is: intake flow channel 142 → connecting chamber 1411 in the installation space 141 → compression chamber 21 in the installation space 141 → exhaust flow channel 143. The driving component is located in the connecting chamber 1411. The refrigerant can exchange heat with the driving component when flowing through the connecting chamber 1411 to cool the driving component, thereby reducing the temperature of the driving component and improving the service life and reliability of the driving component.

[0045] At least a portion of the heating assembly 4 is disposed within the connecting cavity 1411 to fully utilize the space within the connecting cavity 1411 and enhance the structural compactness of the compressor 10. The heating assembly 4 heats the liquid and gaseous refrigerants flowing through the connecting cavity 1411, thereby converting the liquid refrigerant into a gaseous refrigerant and increasing the temperature and pressure of the gaseous refrigerant prior to compression. This allows the compressor 10 to generate heat in a low-temperature environment, thereby increasing the heating capacity of the compressor 10 and reducing defrosting time. Furthermore, the refrigerant has a lower temperature prior to compression, creating a larger temperature difference between the refrigerant and the heating assembly 4, thereby enhancing the heat exchange efficiency between the refrigerant and the heating assembly 4.

[0046] According to the compressor 10 of the embodiment of the present invention, a refrigerant flows through the connecting cavity 1411 where the driving component is located. The refrigerant can cool the driving component, and the heat generated by the driving component can also heat the refrigerant. At the same time, the heating component 4 can heat the refrigerant in the connecting cavity 1411 to increase the temperature of the refrigerant before compression, thereby enhancing the heating performance of the compressor 10 in a low-temperature environment.

[0047] In some embodiments of the present invention, referring to Figure 3 As shown, in the flow direction of the refrigerant in the communicating cavity 1411 , at least a portion of the driving component is located upstream of the heating component 4 .

[0048] Specifically, the flow direction of the refrigerant in the communication cavity 1411 is Figure 3 The refrigerant flows from left to right in the connecting cavity 1411. When at least part of the driving component is located upstream (on the left side) of the heating component 4, the refrigerant in the connecting cavity 1411 can flow from the driving component to the heating component 4, which can reduce the heat transferred from the refrigerant heated by the heating component 4 to the driving component, thereby helping to improve the heating efficiency of the heating component 4 for the refrigerant and reduce the power consumption of the heating component 4.

[0049] In some embodiments of the present invention, referring to Figure 3 and Figure 6 As shown, the drive assembly includes: a motor 31 and a main shaft 32, and the motor 31 is connected to the compression assembly 2 through the main shaft 32. The heating assembly 4 includes: a heating ring 41, and the main shaft 32 is inserted into the heating ring 41. In the axial direction of the main shaft 32, the heating ring 41 is located between the compression assembly 2 and the motor 31.

[0050] Specifically, the motor 31 includes: a stator 311 and a rotor 312. The stator 311 can be fixed to the inner wall of the connecting chamber 1411, and the rotor 312 is connected to the main shaft 32. The flow direction of the refrigerant in the connecting chamber 1411 can be the same as the axial direction of the main shaft 32. When the coil of the stator 311 is energized, a rotating magnetic field is generated to drive the rotor 312 to rotate, so that the rotor 312 drives the main shaft 32 to rotate, and then the main shaft 32 drives the compression component 2 to work.

[0051] The heating ring 41 of the heating assembly 4 can heat the refrigerant in the communicating cavity 1411. The heating ring 41 can be a circular ring structure to increase the heat exchange area between the heating ring 41 and the refrigerant. The heating ring 41 can be placed on the radial outer side of the main shaft 32 to increase the space utilization rate in the communicating cavity 1411. At the same time, in the axial direction of the main shaft 32 (i.e. Figure 3 The left and right directions in the figure), the heating ring 41 is located between the compression assembly 2 and the motor 31. When the refrigerant passes through the connecting cavity 1411, it can flow through the motor 31 and the heating ring 41 in the axial direction of the main shaft 32 and then enter the compression cavity 21. The low-temperature refrigerant can fully cool the motor 31. After being heated by the heating ring 41, the refrigerant can flow into the compression cavity 21 of the compression assembly 2, thereby reducing the heat loss of the refrigerant and improving the heating performance of the compressor 10.

[0052] In some embodiments of the present invention, referring to Figure 3As shown, the drive assembly further includes: a first bracket 33, a first bearing 34, a second bracket 35, and a second bearing 36. The first bracket 33 and the second bracket 35 are both connected to the inner wall of the communication chamber 1411. In the axial direction of the main shaft 32, the motor 31 is located between the first bracket 33 and the second bracket 35. The end of the main shaft 32 away from the compression assembly 2 is rotatably connected to the first bracket 33 via the first bearing 34, and the end of the main shaft 32 close to the compression assembly 2 is rotatably connected to the second bracket 35 via the second bearing 36. In the radial direction of the main shaft 32, the outlet of the suction flow channel 142 corresponds to the first bracket 33, and the heating ring 41 corresponds to the second bracket 35.

[0053] Specifically, the first bracket 33 and the second bracket 35 can be fixedly connected to the inner wall of the connecting cavity 1411 by welding, bonding or fasteners. The first bracket 33 can be used to support and fix the first bearing 34, and the second bracket 35 can be used to support and fix the second bearing 36. The first bearing 34 and the second bearing 36 can support the main shaft 32 at both axial ends of the main shaft 32 and enable the main shaft 32 to rotate stably around its axis. The first bearing 34 and the second bearing 36 can be sliding bearings.

[0054] In the radial direction of the main shaft 32, there is a large space between the first bracket 33 and the inner wall of the connecting chamber 1411. The outlet of the intake air duct 142 is the connection point between the intake air duct 142 and the connecting chamber 1411. When the outlet of the intake air duct 142 corresponds to the first bracket 33 in the radial direction of the main shaft 32, the refrigerant entering the connecting chamber 1411 from the intake air duct 142 first reaches the space between the first bracket 33 and the inner wall of the connecting chamber 1411. The space here is large, which can ensure smooth air intake into the connecting chamber 1411. At the same time, when the refrigerant in the connecting chamber 1411 flows toward the compression component 2, it can flow through the stator 311 and the rotor 312 of the motor 31 to fully cool the motor 31.

[0055] In the radial direction of the main shaft 32, there is also a large space between the second bracket 35 and the inner wall of the connecting cavity 1411. When the heating ring 41 corresponds to the second bracket 35, the heating ring 41 can make full use of the space between the second bracket 35 and the inner wall of the connecting cavity 1411 to improve the space utilization rate of the connecting cavity 1411. At the same time, the refrigerant is heated by the heating ring 41 located here and can flow into the compression cavity 21 of the compression assembly 2, thereby reducing the heat loss of the refrigerant and improving the heating performance of the compressor 10.

[0056] In some embodiments of the present invention, the compression assembly 2 includes: a movable scroll and a stationary scroll. The stationary scroll is fixed in the installation space 141. The main shaft 32 is transmission-connected to the movable scroll. The main shaft 32 can drive the movable scroll to rotate eccentrically and translate, so that the movable scroll and the stationary scroll engage and squeeze to gradually change the volume of the compression chamber 21, thereby realizing the compression of the refrigerant.

[0057] In some embodiments of the present invention, referring to Figure 3 As shown, the drive assembly also includes: a first balancing block 37 and a second balancing block 38. The first balancing block 37 and the second balancing block 38 are both sleeved and fixed on the main shaft 32. In the axial direction of the main shaft 32, the first balancing block 37 is located on one side of the stator 311, and the second balancing block 38 is located on the other side of the stator 311. When the main shaft 32 drives the movable scroll to rotate eccentrically and translate, the first balancing block 37 and the second balancing block 38 can rotate synchronously with the main shaft 32 to offset the unbalanced force generated by the movement of the rotor 312 and the movable scroll, reduce the shaking of the main shaft 32, improve the stability of the main shaft 32, and reduce the vibration and noise of the compressor 10.

[0058] In some embodiments of the present invention, referring to Figure 6 and Figure 7 As shown, the heating ring 41 includes: an insulating outer ring 411, an insulating inner ring 412, an electric heating element 414 and a plurality of heat exchange fins 413. The insulating outer ring 411 abuts against the inner wall of the connecting cavity 1411, and the insulating inner ring 412 is arranged on the radial inner side of the insulating outer ring 411. The insulating inner ring 412 is connected to the second bracket 35. Each heat exchange fin 413 is connected between the insulating outer ring 411 and the insulating inner ring 412. The electric heating element 414 is arranged between the insulating outer ring 411 and the insulating inner ring 412. The electric heating element 414 is thermally connected to each heat exchange fin 413.

[0059] Specifically, the insulating outer ring 411 and the insulating inner ring 412 can be coaxially nested, with the insulating outer ring 411 abutting the inner wall of the communicating cavity 1411 and the insulating inner ring 412 connected to the second bracket 35, to ensure the stability of the heating ring 41 within the communicating cavity 1411 and prevent the heating ring 41 from shaking within the communicating cavity 1411. The insulating inner ring 412 can be provided with a plurality of inner ring brackets 4121, which extend toward the second bracket 35 and can be fixed to the second bracket 35 by fasteners. Optionally, the number of inner ring brackets 4121 is three, and the three inner ring brackets 4121 are evenly arranged at equal intervals along the circumferential direction of the insulating inner ring 412.

[0060] The insulating outer ring 411 can be connected to the insulating inner ring 412 through multiple heat exchange fins 413. The electric heating element 414 can be laid on the inner surface of the insulating outer ring 411 and / or the outer surface of the insulating inner ring 412. The electric heating element 414 is thermally connected to each heat exchange fin 413. After being energized, the electric heating element 414 can convert electrical energy into thermal energy, thereby heating the electric heating element 414 and the heat exchange fins 413 to heat the refrigerant in the connecting cavity 1411. The heat exchange fins 413 can increase the heat exchange area between the heating ring 41 and the refrigerant, which is beneficial to improving the heating efficiency of the heating ring 41 for the refrigerant.

[0061] It should be noted that the insulating outer ring 411 and the insulating inner ring 412 are both made of insulating materials such as ceramics or polymers to achieve electrical insulation between the electric heating element 414 and the shell 1. When the electric heating element 414 leaks electricity, the current is prevented from being conducted to the shell 1, which is beneficial to improving the safety of the compressor 10.

[0062] In some embodiments of the present invention, referring to Figure 6 As shown, the plurality of heat exchange fins 413 are radially arranged relative to the center point of the heating ring 41 , and the normal direction of each heat exchange fin 413 is perpendicular to the radial direction of the heating ring 41 .

[0063] Specifically, the plurality of heat exchange fins 413 are arranged radially outward from the center point of the heating ring 41. That is, the plurality of heat exchange fins 413 can be spaced apart along the circumference of the heating ring 41 to facilitate processing and assembly of the heat exchange fins 413. The normal direction of each heat exchange fin 413 is perpendicular to the radial direction of the heating ring 41. That is, the heat exchange fin 413 extends in the radial direction of the heating ring 41, and the thickness direction of the heat exchange fin 413 is perpendicular to the radial direction of the heating ring 41. When the refrigerant passes through the heating ring 41 along the axial direction of the heating ring 41, the heat exchange fin 413 can reduce the area of ​​the refrigerant blocked by the heat exchange fin 413, thereby reducing the flow rate loss of the refrigerant.

[0064] In some embodiments of the present invention, referring to Figure 7 As shown, a heat exchange window 4133 is provided on the heat exchange fin 413 .

[0065] Specifically, when the refrigerant flows through the heat exchange fins 413, the refrigerant can pass through the heat exchange fins 413 through the heat exchange windows 4133, which can increase the time the refrigerant flows through the heat exchange fins 413. In other words, the heat exchange windows 4133 can increase the heat exchange time between the refrigerant and the heat exchange fins 413, thereby improving the heating effect of the heat exchange fins 413 on the refrigerant. The heat exchange fins 413 can be provided with multiple heat exchange windows 4133. When the heat exchange fins 413 are relatively small in size, the heat exchange between the heat exchange fins 413 and the refrigerant can be increased through the multiple heat exchange windows 4133, thereby increasing the temperature of the refrigerant.

[0066] Among them, the heat exchange window 4133 can be constructed as a through-hole structure. When the refrigerant flows through the heat exchange fins 413, there will be slight differences in the flow rate of the refrigerant on both sides of the heat exchange fins 413. According to Bernoulli's principle, the pressure on the side with a faster flow rate is smaller, so that the refrigerant with a slower flow rate on one side of the heat exchange fins 413 can flow through the heat exchange window 4133 to the other side of the heat exchange fins 413. When passing through the heat exchange window 4133, the refrigerant can fully exchange heat with the heat exchange fins 413 to increase the amount of heating of the refrigerant by the heat exchange fins 413.

[0067] In some embodiments of the present invention, referring to Figure 7As shown, the heat exchange fin 413 includes: a fin body 4131 and a guide plate 4132, and the guide plate 4132 is partially separated from the fin body 4131 to form a heat exchange window 4133

[0068] Specifically, the guide plate 4132 is tilted relative to the fin body 4131, and the guide plate 4132 can guide the refrigerant to the heat exchange window 4133, thereby increasing the heat exchange time between the refrigerant and the heat exchange fin 413. At the same time, the fin body 4131 can transfer heat to the guide plate 4132, and the refrigerant can exchange heat with the guide plate 4132, thereby increasing the heat exchange area between the refrigerant and the heat exchange fin 413, so as to further increase the heating amount of the refrigerant by the heat exchange fin 413.

[0069] It should be noted that the fin body 4131 and the guide plate 4132 can be formed by stamping a metal plate, so the heat exchange fin 413 is easy to mass produce and has a low manufacturing cost.

[0070] In some embodiments of the present invention, referring to Figure 3 and Figure 6 As shown, the compressor 10 also includes: an electronic control module 51, which is arranged outside the installation space 141, and the heating component 4 also includes: a wire and an insulating sleeve 43, the wire is passed through the cavity wall of the connecting cavity 1411, one end of the wire is electrically connected to the electronic control module 51, and the other end of the wire is electrically connected to the electric heating element 414, and the insulating sleeve 43 is covered on the wire.

[0071] Specifically, the electric control module 51 is disposed outside the installation space 141 to facilitate assembly and maintenance of the electric control module 51. The electric control module 51 may be an integrated circuit board. The electric control module 51 may supply power to the electric heating element 414 via a wire.

[0083] In some embodiments of the present invention, referring to Figure 1-Figure 3 As shown, the distribution component 12 also has a bypass flow channel 145, which connects the intake flow channel 142 and the exhaust flow channel 143. The compressor 10 also includes: a first electronic expansion valve 52 and a second electronic expansion valve 53.

[0084] Among them, the first electronic expansion valve 52 can enable the compressor 10 to realize the hot gas bypass function under low-temperature heating conditions to improve the heating capacity of the compressor 10. Specifically, when heating in a low-temperature environment, the first electronic expansion valve 52 can be opened, so that a part of the compressed refrigerant can flow out of the compressor 10 through the exhaust flow channel 143, and the other part of the refrigerant can enter the intake flow channel 142 again through the bypass flow channel 145 and the first electronic expansion valve 52 to achieve re-compression of the refrigerant, thereby improving the heating capacity of the compressor 10.

[0085] The opening of the second electronic expansion valve 53 can adjust the refrigerant flow rate of the exhaust flow channel 143 to achieve exhaust pressure control. By controlling the exhaust pressure, the input power of the compressor 10 can be indirectly changed, thereby changing the heating power of the cold compressor 10.

[0086] In some embodiments of the present invention, referring to Figure 1-Figure 5As shown, the shell body 11 has an intake air channel 142, which includes: a first intake sub-channel 1421, a second intake sub-channel 1422 and a third intake sub-channel 1423.

[0088] The extension direction of the third suction sub-channel 1423 can be tangent to the inner wall of the connecting cavity 1411. When the refrigerant flows into the connecting cavity 1411 through the third suction sub-channel 1423, it can flow smoothly along the inner wall of the connecting cavity 1411 to avoid the refrigerant from forming turbulence at the outlet of the third suction sub-channel 1423, thereby reducing the suction pressure loss of the compressor 10.

The high-voltage connector 57 is suitable for connecting to a high-voltage wiring harness. The high-voltage wiring harness can provide high voltage electricity to the compressor 10 through the high-voltage connector 57. The low-voltage connector 58 is suitable for connecting to a low-voltage wiring harness. The low-voltage wiring harness can provide a low-voltage control signal to the electronic control module 51 through the low-voltage connector 58.

[0093] Specifically, the shell body 11 has a high-voltage connector mounting hole and a low-voltage connector mounting hole. The high-voltage connector 57 is fixed in the high-voltage connector mounting hole and is electrically connected to the electronic control module 51. The low-voltage connector 58 is fixed in the low-voltage connector mounting hole and is electrically connected to the electronic control module 51. The electronic control module 51 can receive the low-voltage control signal transmitted by the low-voltage connector 58, and convert the direct current received by the high-voltage connector 57 into alternating current with adjustable frequency and voltage to power the coil of the stator 311. A rotating magnetic field is generated through the coil of the stator 311, so that the rotor 312 of the motor 31 generates a rotational motion under the action of the rotating magnetic field. The rotational motion is carried out around the axis of the first bearing 34 and the second bearing 36, so that the main shaft 32 drives the compression assembly 2 to work.

[0094] The compressor 10 can be used in vehicles. The high-voltage wiring harness is the high-voltage wiring harness that supplies power to the entire vehicle, and the low-voltage wiring harness is the low-voltage control wiring harness of the entire vehicle. Two pins can be added to the high-voltage connector 57 to verify whether the high-voltage connector 57 is connected to the high-voltage wiring harness. When there is a false connection or a circuit break, the high-voltage wiring harness can stop supplying power to achieve the interlocking function of the high-voltage system and improve the safety of the power supply of the entire vehicle. The vehicle can control the compressor 10 and receive feedback signals from the compressor 10 through the low-voltage wiring harness.

The refrigerant separates the refrigerant and the lubricating oil of the compressor 10 in the oil separation section. The separated lubricating oil can flow into the vicinity of the second bearing 36 through the return oil hole 122 in the distribution component 12 to lubricate the second bearing 36. The end of the oil separation section is connected with the second electronic expansion valve 53 and the exhaust port 124. The exhaust pressure is adjusted by the second electronic expansion valve 53. The exhaust port 124 is connected with the external heat exchange liquid storage component to realize the heat and mass transfer functions between the refrigerant and the thermal management device.

The refrigerant can cool the drive component, and the heat generated by the drive component can also heat the refrigerant. At the same time, the heating component 4 can heat the refrigerant in the connecting cavity 1411 to increase the temperature of the refrigerant before compression, thereby enhancing the heating performance of the compressor 10 in a low-temperature environment and improving the product competitiveness of the thermal management device.

[0098] In some embodiments of the present invention, the thermal management device further includes a heat exchange liquid storage component connected to the compressor 10 and communicating with the intake flow channel 142 and the exhaust flow channel 143 .

Compared with using connecting pipes to connect the various components, the number of connecting pipes is reduced, the integration of the thermal management device is improved, and the total volume of the flow channel in the thermal management device is reduced, reducing the risk of refrigerant leakage. At the same time, the refrigerant filling amount can be greatly reduced and the structural strength of the device can be increased, thereby improving the safety of the thermal management device. It can also save assembly man-hours for the thermal management device and meet the hierarchical assembly requirements of the general assembly line. The reduction in the refrigerant filling amount can increase the safety of flammable and explosive thermal management devices and improve the safety level of the entire vehicle.

[0100] The compressor 10 and the heat exchange liquid storage assembly can be distributed along the axis of the compressor 10, and the heat exchange liquid storage assembly can be connected to the side of the distribution member 12 away from the shell body 11, which can facilitate the connection between the compressor 10 and the heat exchange liquid storage assembly and improve the integration of the thermal management device.
