[0042] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or mutual communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0043] 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.

[0044] Reference Figure 1-Figure 4 As shown, the compressor 10 according to an embodiment of the present invention includes: a shell 1, a drive actuator and a heating assembly 4. The shell 1 has an installation cavity, an intake air duct 142 and an exhaust air duct 143. The drive actuator is arranged in the installation cavity. The drive actuator is used to inhale and compress the refrigerant in the intake air duct 142 and then discharge it into the exhaust air duct 143. The heating assembly 4 is at least partially arranged in the intake air duct 142. The heating assembly 4 is used to heat the refrigerant in the intake air duct 142.

[0045] Among them, the shell 1 is the outer shell of the compressor 10, and the shell 1 defines an installation cavity 141 and an intake duct 142 and an exhaust duct 143 connected to the installation cavity 141. The installation cavity 141 can be used to install the drive execution component. The refrigerant can enter the installation cavity 141 through the intake duct 142, and then be pressurized by the drive execution component and flow out through the exhaust duct 143.

[0046] At least a portion of the heating assembly 4 is disposed within the intake duct 142 to fully utilize the space within the intake duct 142 and enhance the structural compactness of the compressor 10. The heating assembly 4 heats the liquid and gaseous refrigerant flowing through the intake duct 142, 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.

[0047] According to the compressor 10 of the embodiment of the present invention, the heating component 4 is at least partially arranged in the intake air duct 142. The heating component 4 is used to heat the refrigerant in the intake air duct 142 to increase the temperature of the refrigerant before compression, thereby enhancing the heating performance of the compressor 10 in a low-temperature environment. In addition, the compressor 10 has a compact structure and occupies a small space.

[0048] In some embodiments of the present invention, referring to Figure 3 As shown, the drive execution component includes: a compression component 2 and a drive component. The compression component 2 is arranged in the installation cavity 141. The installation cavity 141 forms a connecting cavity 1411 in the area outside the compression component 2. The compression component 2 has a compression cavity 21. The inlet of the compression cavity 21 is connected to the intake flow channel 142 through the connecting cavity 1411. The outlet of the compression cavity 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 a transmission manner.

[0049] Specifically, the compression component 2 is arranged in the installation cavity 141 of the shell 1, and the installation cavity 141 forms a connecting cavity 1411 in the area outside the compression component 2. The driving component is arranged in the connecting cavity 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 cavity 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 cavity 1411 in the installation cavity 141 → compression chamber 21 in the installation cavity 141 → exhaust flow channel 143. The driving component is located in the connecting cavity 1411. When the refrigerant flows through the connecting cavity 1411, it can exchange heat with the driving component to heat the driving component, thereby increasing the temperature of the driving component and ensuring that the driving component can operate normally at low temperatures.

[0050] In some embodiments of the present invention, referring to Figure 3 As shown, the driving assembly includes: a motor 31 and a main shaft 32 , and the motor 31 is transmission-connected to the compression assembly 2 via the main shaft 32 .

[0051] 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.

[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.

[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 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 mounting cavity 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 cavity 21, thereby realizing the compression of the refrigerant.

[0056] In some embodiments of the present invention, referring to Figure 3As 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.

[0057] In some embodiments of the present invention, referring to Figure 4-Figure 6 As shown, the intake air channel 142 includes: a first intake sub-channel 1421 and a second intake sub-channel 1422. The first intake sub-channel 1421 extends along the axial direction of the compressor 10. In the radial direction of the compressor 10, the first intake sub-channel 1421 corresponds to the installation cavity. At least part of the heating component 4 is arranged in the first intake sub-channel 1421. One end of the second intake sub-channel 1422 is connected to the first intake sub-channel 1421, and the other end of the second intake sub-channel 1422 is connected to the installation cavity.

[0058] Specifically, the first suction sub-channel 1421 is connected to the installation cavity through the second suction sub-channel 1422. The axial direction of the compressor 10 is the axial direction of the main shaft 32, and the radial direction of the compressor 10 is the radial direction of the main shaft 32. When the first suction sub-channel 1421 extends along the axial direction of the compressor 10, and the first suction sub-channel 1421 corresponds to the installation cavity in the axial direction of the compressor 10, the first suction sub-channel 1421 has a larger length, so as to facilitate the installation of the heating component 4 in the first suction sub-channel 1421, and make the refrigerant flowing through the first suction sub-channel 1421 have a longer heat exchange time with the heating component 4, thereby improving the heating effect of the heating component 4 on the refrigerant. At the same time, the first suction sub-channel 1421 occupies a smaller space, so that the structure of the compressor 10 is compact and the occupied space of the compressor 10 is reduced.

[0059] In some embodiments of the present invention, referring to Figure 4 and Figure 5 As shown, the second air suction sub-channel 1422 includes: an outlet section 14222 and a connecting section 14221. The outlet section 14222 is connected to the installation cavity, and the extension direction of the outlet section 14222 is tangent to the inner wall of the installation cavity. One end of the connecting section 14221 is connected to the first air suction sub-channel 1421, and the other end of the connecting section 14221 is connected to the outlet section 14222.

[0060] Specifically, when the refrigerant enters the installation cavity from the intake flow channel 142, the refrigerant flows through the first intake sub-channel 1421, the connecting section 14221 of the second intake sub-channel 1422 and the outlet section 14222 of the second intake sub-channel 1422 in turn. When the extension direction of the outlet section 14222 is tangent to the inner wall of the installation cavity, the refrigerant can flow smoothly along the inner wall of the outlet section 14222 when flowing into the connecting cavity 1411 through the outlet section 14222, so as to avoid the formation of turbulence of the refrigerant at the outlet of the outlet section 14222, thereby reducing the intake pressure loss of the compressor 10.

[0061] In some embodiments of the present invention, referring to Figure 4-Figure 6 As shown, the extension direction of the connecting section 14221 can be perpendicular to the extension direction of the first air intake sub-channel 1421, and the plane where the axis of the connecting section 14221 and the axis of the outlet section 14222 are located can be perpendicular to the axis of the first air intake sub-channel 1421, so as to facilitate the processing of the first air intake sub-channel 1421, the connecting section 14221 and the outlet section 14222 on the blank of the shell 1 through a drilling process, thereby reducing the processing difficulty of the air intake channel 142, and the open process hole formed by drilling on the surface of the shell 1 can be sealed by a sealing plug 151, and the sealing plug 151 and the open process hole are sealed and fixed by a thread and a sealing ring 48, or the sealing plug 151 and the open process hole are sealed and fixed by welding.

[0062] In some embodiments of the present invention, referring to Figure 7-Figure 9 As shown, the heating assembly 4 includes: a heating tube 41 and a plurality of heat exchange fins 42. The heating tube 41 is arranged in the first air intake sub-channel 1421. The axial direction of the heating tube 41 is the same as the extension direction of the first air intake sub-channel 1421. The plurality of heat exchange fins 42 are radially connected to the outside of the heating tube 41 with the axis of the heating tube 41 as the center, and the normal direction of each heat exchange fin 42 is perpendicular to the radial direction of the heating tube 41.

[0063] Specifically, the heating tube 41 can extend along the length direction of the first air intake sub-channel 1421 so that the heating tube 41 can fully heat the refrigerant flowing through the first air intake sub-channel 1421. Multiple heat exchange fins 42 are connected to the heating tube 41. When the heating tube 41 heats up, the heating tube 41 can heat each heat exchange fin 42, thereby increasing the heat exchange area between the heating component 4 and the refrigerant through multiple heat exchange fins 42, thereby improving the heating efficiency of the heating component 4.

[0064] The multiple heat exchange fins 42 are arranged radially outward from the axis of the heating tube 41. In other words, the multiple heat exchange fins 42 can be spaced apart along the circumference of the heating tube 41 to facilitate processing and assembly of the heat exchange fins 42. The normal direction of each heat exchange fin 42 is perpendicular to the radial direction of the heating tube 41. In other words, the heat exchange fins 42 extend in the radial direction of the heating tube 41, and the thickness direction of the heat exchange fins 42 is perpendicular to the radial direction of the heating tube 41. When the refrigerant passes through the first suction sub-channel 1421 along the axial direction of the heating tube 41, the heat exchange fins 42 can reduce the area of ​​the refrigerant blocked by the refrigerant, thereby reducing the flow rate loss of the refrigerant.

[0065] In some embodiments of the present invention, referring to Figure 10 As shown, a heat exchange window 423 is provided on the heat exchange fin 42 .

[0066] Specifically, when the refrigerant flows through the heat exchange fins 42, it can pass through the heat exchange windows 423, which can increase the time the refrigerant flows through the heat exchange fins 42. In other words, the heat exchange windows 423 can increase the heat exchange time between the refrigerant and the heat exchange fins 42, thereby improving the heating effect of the heat exchange fins 42 on the refrigerant. The heat exchange fins 42 can be provided with multiple heat exchange windows 423. When the heat exchange fins 42 are relatively small in size, the heat exchange between the heat exchange fins 42 and the refrigerant can be increased through the multiple heat exchange windows 423, thereby increasing the temperature of the refrigerant.

[0067] Among them, the heat exchange window 423 can be constructed as a through-hole structure. When the refrigerant flows through the heat exchange fins 42, there will be slight differences in the flow rate of the refrigerant on both sides of the heat exchange fins 42. According to Bernoulli's principle, the pressure on the side with a faster flow rate is smaller, so that the refrigerant with a slow flow rate on one side of the heat exchange fins 42 can flow through the heat exchange window 423 to the other side of the heat exchange fins 42. When passing through the heat exchange window 423, the refrigerant can fully exchange heat with the heat exchange fins 42 to increase the amount of heating of the refrigerant by the heat exchange fins 42.

[0068] In some embodiments of the present invention, referring to Figure 10 As shown, the heat exchange fin 42 includes a fin body 421 and a guide plate 422 . The guide plate 422 is partially separated from the fin body 421 to form a heat exchange window 423 .

[0069] Specifically, the guide plate 422 is tilted relative to the fin body 421, and the guide plate 422 can guide the refrigerant to the heat exchange window 423, thereby increasing the heat exchange time between the refrigerant and the heat exchange fin 42. At the same time, the fin body 421 can transfer heat to the guide plate 422, and the refrigerant can exchange heat with the guide plate 422, thereby increasing the heat exchange area between the refrigerant and the heat exchange fin 42, so as to further increase the heating amount of the heat exchange fin 42 to the refrigerant.

[0070] It should be noted that the fin body 421 and the guide plate 422 can be formed from a piece of metal plate by stamping, so the heat exchange fin 42 is easy to mass produce and has a low manufacturing cost.

[0071] In some embodiments of the present invention, referring to Figure 7-Figure 9 As shown, the heating assembly 4 further includes: a flow guide head 43 , which is connected to the end of the heating tube 41 close to the inlet of the suction flow channel 142 .

[0072] Specifically, the guide head 43 can be a conical structure. In the flow direction of the refrigerant in the intake air duct 142, the cross-sectional area of ​​the guide head 43 gradually increases. When the refrigerant enters the first intake sub-flow channel 1421 from the inlet of the intake air duct 142, the guide head 43 can form a guiding effect on the refrigerant at the upstream end of the heating tube 41 to reduce the refrigerant directly hitting the end of the heating tube 41 to form turbulence, thereby reducing the intake pressure loss of the compressor 10.

[0073] In some embodiments of the present invention, referring to Figure 7-Figure 9 As shown, the heating assembly 4 further includes: a clamp 44 , which is sleeved and fixed on the outer sides of the plurality of heat exchange fins 42 , and the clamp 44 is interference fit with the inner wall of the first air suction sub-channel 1421 .

[0074] Specifically, the clamp 44 can be mounted radially outside the plurality of heat exchange fins 42. When the heating assembly 4 is installed in the first air intake sub-channel 1421, the clamp 44 is tightened by the inner wall of the first air intake sub-channel 1421, so that the clamp 44 and the inner wall of the first air intake sub-channel 1421 form an interference fit. The heating assembly 4 can be fixed in the first air intake sub-channel 1421 by the clamp 44 to prevent the heating assembly 4 from shaking in the first air intake sub-channel 1421. At the same time, the clamp 44 can also support and reinforce the radial outer ends of the plurality of heat exchange fins 42, reducing the risk of vibration of the heat exchange fins 42 under the blowing of the refrigerant. Optionally, there are multiple clamps 44, and the multiple clamps 44 are arranged at intervals along the axial direction of the heating tube 41.

[0075] In some embodiments of the present invention, referring to Figure 9 As shown, the heating tube 41 includes: a heating core 411, an insulating sleeve 412 and a heat-conducting sleeve 413.

At the same time, the refrigerant heated by the electronic control module 51 can also enhance the heating capacity of the compressor 10.
