A connecting channel is provided between the high-pressure chamber and the back-pressure chamber. A throttling element is provided in the connecting channel. The outer peripheral wall of the throttling element and the inner wall of the connecting channel define a throttling channel for the medium to pass through.

[0037] The following is for reference. Figures 1-6 This invention describes a horizontal scroll compressor 100 for a vehicle according to an embodiment of the present invention.

[0038] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, a horizontal scroll compressor 100 for a vehicle includes: a housing 1, a drive assembly 2, and a compression assembly 3. The drive assembly 2 and the compression assembly 3 are respectively disposed on the housing 1, and the drive assembly 2 is adapted to drive the compression assembly 3 to compress refrigerant.

[0039] The housing 1 contains a high-pressure chamber 11, a low-pressure chamber 12, and an oil storage chamber 13. The oil storage chamber 13 is connected to the high-pressure chamber 11. The housing 1 has an air inlet 141 connected to the low-pressure chamber 12 and an air outlet 151 connected to the high-pressure chamber 11. The air inlet 141 and the air outlet 151 are used to connect to an external working circuit. The refrigerant in the external working circuit can enter the horizontal scroll compressor 100 through the air inlet 141, and the refrigerant compressed by the compression assembly 3 can be discharged through the air outlet 151 and re-enter the external working circuit.

[0040] The housing 1 is provided with a bracket 4. It should be noted that the bracket 4 can be completely disposed inside the housing 1, or it can be formed as part of the housing 1. For example, in some embodiments, the housing 1 includes a first housing 14 and a second housing 15 spaced apart, with the bracket 4 sandwiched between the first housing 14 and the second housing 15. In this embodiment, the bracket 4 is part of the housing 1. It should also be noted that in embodiments where the bracket 4 is completely disposed inside the housing 1, the bracket 4 can be integrally formed with the housing 1, or it can be a separate component, as long as the bracket 4 is fixedly disposed on the housing 1. In embodiments where the bracket is sandwiched between the first housing 14 and the second housing 15, the bracket 4 can be integrally formed with the first housing 14 and / or the second housing 15, or the bracket 4, the first housing 14, and the second housing 15 can be three separate components, as long as the bracket 4, the first housing 14, and the second housing 15 are fixedly disposed.

[0041] The drive assembly 2 is located within the low-pressure chamber 12 and includes a crankshaft 21 passing through the bracket 4. The compression assembly 3 includes a moving scroll 31 and a stationary scroll 32. The stationary scroll 32 is disposed on the housing 1 and stationary relative to the housing 1. The moving scroll 31 meshes with the stationary scroll 32, forming a compression chamber 33 between the moving scroll 31 and the stationary scroll 32. The moving scroll 31 is rotatable relative to the stationary scroll 32. The crankshaft 21 of the drive assembly 2 is connected to the moving scroll 31 for transmission. That is, the drive assembly 2 can drive the moving scroll 31 to rotate relative to the stationary scroll 32 through the crankshaft 21, so that the compression assembly 3 can compress the refrigerant.

[0042] The intake port of the compression chamber 33 is connected to the low-pressure chamber 12, and the exhaust port 331 of the compression chamber 33 is connected to the high-pressure chamber 11. Therefore, when the horizontal scroll compressor 100 is working, the drive assembly 2 drives the moving scroll 31 to rotate relative to the stationary scroll 32 through the crankshaft 21, so that the compression assembly 3 can compress the refrigerant. The refrigerant in the external working circuit can enter the low-pressure chamber 12 through the intake port 141, and then enter the compression chamber 33 through the intake port. The compressed high-pressure refrigerant enters the high-pressure chamber 11 through the exhaust port 331, and then is discharged through the outlet port 151 and re-enters the external working circuit.

[0043] In this embodiment of the present invention, a back pressure cavity 41 is provided between the moving scroll 31 and the support 4. A groove is provided on the side of the support 4 facing the moving scroll 31. The moving scroll 31 closes the groove to define the back pressure cavity 41. The gas in the back pressure cavity 41 can exert a force on the moving scroll 31 to ensure the axial balance of the moving scroll 31.

[0044] The horizontal scroll compressor 100 according to an embodiment of the present invention further includes a plurality of throttling elements 5. The oil storage chamber 13 and the back pressure chamber 41 are connected through the throttling elements 5, and the back pressure chamber 41 and the low pressure chamber 12 are connected through the throttling elements 5. At least one throttling element 5 is configured as a capillary structure.

[0045] It should be noted that the fluid discharged from the compression chamber 33 through the exhaust port 331 is a mixture of refrigerant and refrigeration oil. The high-pressure chamber 11 is equipped with an oil separator 16, which separates the refrigerant and refrigeration oil mixture into oil and gas. The separated refrigerant is discharged through the exhaust port 151, and the separated refrigeration oil enters the oil storage chamber 13 of the high-pressure chamber 11. The refrigeration oil in the oil storage chamber 13 can enter the back pressure chamber 41 through the throttling element 5 to lubricate the friction pairs within the back pressure chamber 41. The refrigeration oil in the back pressure chamber 41 can also enter the low-pressure chamber 12 through the throttling element 5 to lubricate the friction pairs within the low-pressure chamber 12.

[0046] According to the horizontal scroll compressor 100 of this utility model embodiment, the oil storage chamber 13 can be connected to the back pressure chamber 41 through a capillary tube. The medium in the oil storage chamber 13 can enter the back pressure chamber 41 after being throttled by the capillary tube. The throttling effect of the capillary tube is only related to the inner diameter and length of the capillary tube, that is, the throttling pressure reduction value of the capillary tube is stable. Since the oil storage chamber 13 is connected to the high pressure chamber 11, the pressure in the oil storage chamber 13 is the same as the pressure in the high pressure chamber 11. After the medium in the oil storage chamber 13 is throttled and depressurized by the capillary tube, the medium entering the back pressure chamber 41 is depressurized to a set value, thereby enabling the back pressure chamber 41 to obtain a stable back pressure value. The performance of the horizontal scroll compressor 100 is more likely to meet the design expectations. In addition, in this utility model embodiment, the back pressure chamber 41 and the low pressure chamber 12 can also be connected through a capillary tube, which reduces the influence of the medium flowing out of the back pressure chamber 41 on the pressure in the low pressure chamber 12 and ensures the reliability of the horizontal scroll compressor 100.

[0047] In some specific embodiments, the housing 1 includes a first housing 14 and a second housing 15. The first housing 14 is open on the side facing the second housing 15. A bracket 4 is disposed at the opening of the first housing 14 and closes the opening of the first housing 14. The low-pressure chamber 12 is defined between the first housing 14 and the bracket 4. The air inlet 141 is formed on the first housing 14. A stationary scroll 32 is disposed on the side of the bracket 4 away from the first housing 14. A moving scroll 31 is disposed between the bracket 4 and the stationary scroll 32, such that the back pressure chamber 41 is defined between the bracket 4 and the moving scroll 31, and the compression chamber 33 is defined between the moving scroll 31 and the stationary scroll 32.

[0048] The second housing 15 is located on the side of the stationary vortex disk 32 away from the support 4. That is, the stationary vortex disk 32 is sandwiched between the support 4 and the second housing 15. The second housing 15 is provided with the aforementioned high-pressure chamber 11 and air outlet 151.

[0049] In this embodiment of the invention, the connection between the compression component 3 and the housing 1 is simple, which improves the assembly efficiency of the horizontal scroll compressor 100.

[0050] In some specific embodiments, the crankshaft 21 is located within the first housing 14 and is rotatable relative to the first housing 14. The first housing 14 is provided with a first bearing 211 for supporting the crankshaft 21, and the bracket 4 is provided with a second bearing 212 for supporting the crankshaft 21. The second bearing 212 is located within the back pressure chamber 41. That is, one end of the crankshaft 21 is rotatably mounted on the first housing 14 via the first bearing 211, and the other end of the crankshaft 21 is rotatably mounted on the bracket 4 via the second bearing 212.

[0051] The drive assembly 2 also includes a stator 22 and a rotor 23. The stator 22 is disposed on the inner wall of the first housing 14, and the rotor 23 is sleeved on the crankshaft 21. The stator 22 and the rotor 23 are coupled together. When the drive assembly 2 is working, the stator 22 drives the crankshaft 21 to rotate through the rotor 23, so that the crankshaft 21 can drive the rotating scroll 31 to rotate.

[0052] The compression assembly 3 includes a moving scroll 31, a stationary scroll 32, and an anti-rotation structure. The stationary scroll 32 is located on the side of the support 4 facing away from the first housing 14 and is fixedly mounted relative to the support 4. The stationary scroll 32 includes an end plate and a fixed scroll. The moving scroll 31 is located on the side of the stationary scroll 32 facing the support 4. The moving scroll 31 includes an end plate and a moving scroll. The fixed scroll and the moving scroll mesh with each other, thereby defining a compression cavity 33 between the fixed scroll and the moving scroll. The anti-rotation structure is used to limit the rotation of the moving scroll 31 while allowing the moving scroll 31 to perform rotational translational motion relative to the stationary scroll 32.

[0053] An eccentric sleeve 24 is provided at one end of the crankshaft 21 facing the moving scroll 31. The eccentric sleeve 24 is located in the back pressure cavity 41. The crankshaft 21 is adapted to drive the moving scroll 31 to rotate through the eccentric sleeve 24. A third bearing 25 is provided between the eccentric sleeve 24 and the moving scroll 31 so that the crankshaft 21 can drive the moving scroll 31 to perform a rotary translational motion relative to the stationary scroll 32.

[0054] When the horizontal scroll compressor 100 is working, the stator 22 drives the crankshaft 21 to rotate through the rotor 23. The crankshaft 21 drives the moving scroll 31 to rotate and translate relative to the stationary scroll 32 through the eccentric sleeve 24, so that the refrigerant can be compressed in the compression chamber 33. The refrigerant in the external working circuit is drawn into the low-pressure chamber 12 through the air inlet 141, and then into the compression chamber 33 through the air intake for compression. The compressed high-pressure refrigerant enters the high-pressure chamber 11 through the exhaust port 331, and then is discharged through the air outlet 151.

[0055] In this embodiment of the invention, the drive assembly 2 inside the horizontal scroll compressor 100 has a simple structure, which reduces the cost of the horizontal scroll compressor 100.

[0056] In some embodiments, the stationary vortex disk 32 is provided with a first mounting hole 321 for placing the throttling element 5. The two ends of the first mounting hole 321 are respectively connected to the oil storage chamber 13 and the back pressure chamber 41. The crankshaft 21 is provided with a second mounting hole 213 for placing the throttling element 5. The two ends of the second mounting hole 213 are respectively connected to the back pressure chamber 41 and the low pressure chamber 12. Each throttling element 5 is configured as a capillary structure.

[0057] In the above technical solution, the oil storage chamber 13 and the back pressure chamber 41 are connected by a capillary structure, and the back pressure chamber 41 and the low pressure chamber 12 are also connected by a capillary structure. This makes the pressure difference between the oil storage chamber 13 and the back pressure chamber 41, as well as the pressure difference between the back pressure chamber 41 and the low pressure chamber 12, more controllable. This is beneficial to improving the stability of the pressure in the back pressure chamber 41 and the low pressure chamber 12, making it easier for the performance of the horizontal scroll compressor 100 to meet design expectations.

[0058] It should be understood that in other embodiments, the second mounting hole 213 may also be provided on the bracket 4, as long as the back pressure cavity 41 can communicate with the low pressure cavity 12. This utility model does not limit this.

[0059] In some further embodiments, each throttling element 5 is configured as a capillary structure, and a connector 6 is provided between the throttling element 5 and the corresponding mounting hole. The connector 6 is provided with a mounting through hole 61 and a flow area 62 communicating with the mounting through hole 61. At least a portion of the throttling element 5 is located within the mounting through hole 61.

[0060] Through the above technical solution, each throttling element 5 is a capillary structure. The throttling element 5 is installed in the corresponding mounting hole through the connector 6, which improves the installation efficiency of the throttling element 5. Furthermore, a part of the throttling element 5 is located in the mounting through hole 61 of the connector 6, which can protect this part of the throttling element 5 and reduce the risk of deformation of the throttling element 5.

[0061] In some specific embodiments, the capillary structure includes a high-pressure end and a low-pressure end, the medium within the capillary structure is adapted to flow from the high-pressure end to the low-pressure end, and the high-pressure end of the capillary structure is located within the mounting through hole 61.

[0062] Through the above technical solution, the high-pressure medium needs to enter the installation through hole 61 through the flow area 62 before it can enter the capillary structure, which reduces the turbulence of the medium entering the capillary structure and improves the smoothness of the medium flow in the capillary structure.

[0063] In some further embodiments, the flow area 62 is a plurality of perforations on the outer peripheral wall of the connector 6. By setting the perforations on the outer peripheral wall of the connector 6, the high-pressure medium is prevented from directly rushing into the capillary structure, and the turbulence of the medium entering the capillary structure is further reduced.

[0064] In some specific embodiments, the capillary structure and the connector 6 are injection molded together. It should be understood that in other embodiments, the capillary structure and the connector 6 can also be connected by other means such as snap-fitting or bonding. This utility model does not limit this.

[0065] In some embodiments, a sealing element 7 is provided between the connector 6 and the inner wall of the mounting hole, which reduces the risk of the medium passing between the connector 6 and the inner wall of the mounting hole, ensuring that the medium can only pass through the throttling element 5, making the throttling effect more controllable and ensuring the performance of the horizontal scroll compressor 100.

[0066] In some specific embodiments, the outer peripheral wall of the connector 6 is provided with a limiting groove 63, and the sealing member 7 is constructed as a sealing ring disposed in the limiting groove 63.

[0067] In this embodiment of the invention, the installation method of the sealing element 7 is simple, which improves the assembly efficiency of the horizontal scroll compressor 100.

[0068] Reference Figure 3 In some specific embodiments, a first limiting surface 322 is provided in the first mounting hole 321, and the first limiting surface 322 abuts against the connector 6 to limit the displacement of the connector 6.

[0069] The above technical solution improves the stability of the throttling element 5 and reduces the risk of displacement of the throttling element 5.

[0070] Reference Figure 4 In some embodiments, the second mounting hole 213 includes a first portion 2131 and a second portion 2132. The first portion 2131 extends along the axial direction of the crankshaft 21, and the second portion 2132 is used to connect the first portion 2131 and the back pressure chamber 41. The throttling element 5 is disposed in the first portion 2131.

[0071] In this embodiment of the present invention, the first part 2131 extends along the axial direction of the crankshaft 21, and the throttling element 5 is disposed in the first part 2131, which facilitates the installation of the throttling element 5 and improves the assembly efficiency of the horizontal scroll compressor 100.

[0072] Reference Figure 1 In some other embodiments, the second mounting hole 213 includes a first portion 2131 and a second portion 2132, the first portion 2131 extending along the axial direction of the crankshaft 21, the second portion 2132 for connecting the first portion 2131 and the low-pressure chamber 12, and the throttling element 5 disposed in the first portion 2131.

[0073] In other words, regardless of whether the throttling element 5 is located at the end of the crankshaft 21 near the low-pressure chamber 12 or on the side near the back-pressure chamber 41, it can achieve the effect of throttling and reducing pressure. This utility model does not limit the specific location of this throttling element 5.

[0074] Reference Figure 1 In some specific embodiments, the first part 2131 is located at the end of the crankshaft 21 connected to the moving scroll 31, and the first part 2131 is offset from the central axis of the crankshaft 21.

[0075] Because the end of the crankshaft 21 connected to the moving scroll 31 needs to be fitted with an eccentric sleeve 24 via a crank pin 26, the end of the crankshaft 21 connected to the moving scroll 31 is provided with an insertion hole 214 for mounting the crank pin 26. In this embodiment of the invention, the first part 2131 is offset from the central axis of the crankshaft 21, which increases the distance between the first part 2131 and the insertion hole 214, ensuring the overall strength of the crankshaft 21 structure and extending the service life of the horizontal scroll compressor 100.

[0076] Reference Figure 1 In some further embodiments, the diameter of the first portion 2131 is smaller than the diameter of the second portion 2132, which forms the central channel of the crankshaft 21.

[0077] Through the above technical solution, the medium in the back pressure chamber 41 first passes through the first part 2131 with a relatively small diameter, and then through the second part 2132 with a relatively large diameter, which helps to reduce the pulsation of the flowing medium and reduce the noise of the horizontal scroll compressor 100.

[0078] Reference Figure 4 In some embodiments, the first portion 2131 is formed as the central channel of the crankshaft 21, the diameter of the first portion 2131 is larger than the diameter of the second portion 2132, and the second portion 2132 extends obliquely toward a direction that is offset from the central axis of the crankshaft 21 and toward the moving scroll 31.

[0079] In the above technical solution, the throttling element 5 is disposed in the central channel of the crankshaft 21, which further improves the ease of installation of the throttling element 5; the second part 2132 extends obliquely in a direction away from the central axis of the crankshaft 21 and toward the moving scroll 31, which further increases the distance between the second part 2132 and the insertion hole 214, ensuring the overall strength of the crankshaft 21 structure and extending the service life of the horizontal scroll compressor 100. In addition, the crankshaft 21 in this embodiment has a simple structure, is easy to process, and reduces the cost of the horizontal scroll compressor 100.

[0085] The above technical solution further limits the diameter of the first capillary, further improving the control of the back pressure value of the back pressure chamber 41, so that the medium in the back pressure chamber 41 can more strongly push the moving vortex disk 31 towards the stationary vortex disk 32. In some specific embodiments, the diameter D1 of the first capillary is any one of 0.2mm, 0.4mm, 0.6mm, and 0.8mm, or a range between any two.

[0086] Reference Figure 6 In some embodiments, the length of the first capillary is L1, and the length of the second capillary is L2.

[0087] In the above technical solution, by limiting the range of the ratio of the length of the first capillary to the length of the second capillary, the throttling effect of the first and second capillary tubes can be limited, and the back pressure value of the back pressure chamber 41 can be adjusted, thereby affecting the energy efficiency of the horizontal scroll compressor 100. (Refer to...) Figure 6 It can be seen that when The horizontal scroll compressor 100 exhibits high energy efficiency when its efficiency is within the range of 0.4-1.2. In some specific embodiments, It can be any one of the point values ​​of 0.4, 0.5, 0.8, 0.9, and 1.2, or a range of values ​​between any two.

[0088] In some embodiments, the length L1 of the first capillary satisfies: 15mm≤L1≤40mm.

[0089] The above technical solution further limits the length of the first capillary tube, further improving the control of the back pressure value of the back pressure chamber 41, so that the medium in the back pressure chamber 41 can push the moving vortex disk 31 more strongly towards the stationary vortex disk 32. In some specific embodiments, the length L1 of the first capillary tube is any one of 15mm, 20mm, 30mm, and 40mm, or a range between any two.
