Technical Field

[0001] This application relates to the field of compressor technology, and in particular to a horizontal scroll compressor for vehicles, an air conditioner, and a vehicle. Background Technology

[0002] Horizontal scroll compressors are high-efficiency, low-noise, and stable-operating positive displacement compressors, widely used in automotive air conditioning systems.

[0003] In related technologies, a horizontal scroll compressor includes a compression chamber, an oil separator chamber, an oil outlet channel, and an oil storage chamber. The compressed refrigerant and refrigeration oil mixture in the compression chamber is suitable for discharge into the oil separator chamber. The refrigerant and refrigeration oil mixture is separated in the oil separator chamber. The separated refrigerant is discharged from the horizontal scroll compressor through the refrigerant outlet, and the separated refrigeration oil enters the oil storage chamber through the oil outlet channel. The bottom of the oil storage chamber is provided with an oil return hole communicating with the oil return channel, allowing the refrigeration oil in the oil storage chamber to enter the oil return channel for reuse.

[0004] A horizontal scroll compressor includes a stationary scroll and an oil separator housing. A sealing gasket is provided between the oil separator housing and the stationary scroll. Part of the sealing gasket helps to define the oil outlet channel. However, because the sealing gasket is relatively weak, the part of the sealing gasket that defines the oil outlet channel is prone to damage when the horizontal scroll compressor is working, which affects the use of the horizontal scroll compressor.

[0031] The following is for reference. Figures 1-4 This invention describes a horizontal scroll compressor 100 for a vehicle according to an embodiment of the present invention.

[0032] 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 compression component 3 and an oil separator housing 12. The compression component 3 includes a moving scroll 31 and a stationary scroll 32 that engage with each other. The moving scroll 31 and the stationary scroll 32 cooperate to define a compression chamber 33. The oil separator housing 12 is connected to the stationary scroll 32. The oil separator housing 12 defines or participates in defining an oil separator chamber 122 and an oil storage chamber 123. The compression chamber 33 communicates with the oil separator chamber 122. The oil separator chamber 122 is provided with a refrigerant outlet 121 for refrigerant discharge.

[0033] The oil separator shell 12 has a first groove 124 on the side facing the stationary vortex disk 32. The stationary vortex disk 32 encloses the first groove 124. The oil separator shell 12 has a first rib 125 located inside the first groove 124 and protruding towards the stationary vortex disk 32. The first rib 125, the inner wall of the first groove 124, and the stationary vortex disk 32 define an oil outlet channel 16. The oil outlet channel 16 has an oil inlet 161 and an oil outlet 162. The oil outlet channel 16 communicates with the oil separator chamber 122 through the oil inlet 161 and with the oil storage chamber 123 through the oil outlet 162. The oil outlet 162 is located above the oil inlet 161. It should be noted that the oil outlet 162 being located above the oil inlet 161 means that in the vertical direction, the oil outlet 162 is located directly above or diagonally above the oil inlet 161.

[0034] In this embodiment of the application, when the horizontal scroll compressor 100 is working, the compression component 3 is adapted to compress the refrigerant. The mixture of refrigerant and refrigeration oil compressed in the compression chamber 33 enters the oil separator chamber 122. The mixture of refrigerant and refrigeration oil is separated in the oil separator chamber 122. The separated refrigerant is discharged from the horizontal scroll compressor 100 through the refrigerant outlet 121. The separated refrigeration oil enters the oil outlet channel 16 through the oil inlet 161 and then enters the oil storage chamber 123 through the oil outlet 162.

[0035] According to the horizontal scroll compressor 100 of this utility model embodiment, the refrigerant oil in the oil separator 122 needs to pass through the oil outlet channel 16 to enter the oil storage chamber 123. Furthermore, the oil outlet 162 of the oil outlet channel 16 is located above the oil inlet 161, causing the refrigerant oil to overcome gravity within the oil outlet channel 16 to enter the oil storage chamber 123. This effectively reduces the speed and pressure of the refrigerant oil flowing out of the oil outlet 162, thereby reducing the impact force of the refrigerant oil entering the oil storage chamber 123 on the existing refrigerant oil in the oil storage chamber 123. The stability of the refrigerant oil in the oil storage chamber 123 is improved, ensuring that the oil return hole 322 at the bottom of the oil storage chamber 123 is always submerged in refrigerant oil. This reduces the risk of refrigerant leakage into the oil return channel 323 through the oil return hole 322, improving the refrigeration efficiency of the horizontal scroll compressor 100. Simultaneously, it ensures sufficient oil return to the horizontal scroll compressor 100, allowing for effective lubrication of the friction pairs, improving the compression efficiency of the horizontal scroll compressor 100, and extending its service life. Furthermore, the oil outlet channel 16 is defined by the first rib 125, the inner wall of the first groove 124, and the stationary scroll 32. The inner wall of the oil outlet channel 16 has sufficient strength, reducing the risk of damage to the oil outlet channel 16 and the risk of refrigerant oil leakage from any damaged area. This ensures the reliability of the oil outlet channel 16 and extends the service life of the horizontal scroll compressor 100.

[0036] In this embodiment of the application, the first tank 124 is further provided with a first communication port 1241 that communicates with the oil distribution chamber 122. The first communication port 1241 communicates with the oil outlet channel 16 and is located above the oil outlet channel 16.

[0037] Because the flow rate and pressure of the refrigeration oil will decrease after it flows through the oil outlet channel 16, some of the refrigerant dissolved in the refrigeration oil will precipitate out of the refrigeration oil discharged from the oil outlet channel 16. In this embodiment, the first tank 124 is connected to the oil separator 122 through the first connecting port 1241, so that the precipitated refrigerant can enter the oil separator 122 from the first connecting port 1241 and then be discharged from the refrigerant outlet 121.

[0038] In the above technical solution, the first tank 124 and the oil distribution chamber 122 are connected by the first connecting port 1241, so that excess refrigerant in the first tank 124 can be discharged in time, reducing the risk of refrigerant passing through the oil return hole 322 and reducing the risk of pressure rise in the first tank 124. This ensures that the pressure at the oil inlet 161 of the oil outlet channel 16 is always greater than the pressure at the oil outlet 162. Under the action of pressure difference, it ensures that the refrigeration oil can be discharged smoothly from the oil outlet 162 of the oil outlet channel 16, avoiding the phenomenon of refrigeration oil backflow in the oil outlet channel 16 and improving the reliability of the oil outlet channel 16.

[0039] In this embodiment, the first connecting port 1241 is located above the oil outlet channel 16, which reduces the risk that the refrigeration oil discharged from the oil outlet 162 of the oil outlet channel 16 will come into contact with the first connecting port 1241, and reduces the risk that the refrigeration oil in the first tank 124 will re-enter the oil separator 122 through the first connecting port 1241.

[0040] In some specific embodiments, the first rib 125 includes a first side 1251 and a second side 1252 facing away from each other. The oil outlet channel 16 is defined between the first side 1251, the inner wall of the first groove 124 and the stationary vortex disk 32. The oil storage cavity 123 is defined between the second side 1252, the inner wall of the first groove 124 and the stationary vortex disk 32.

[0041] In this embodiment, the formation of the oil storage chamber 123 is relatively simple, reducing the cost of the horizontal scroll compressor 100. In other embodiments, the oil storage chamber 123 may also be a space defined solely by the oil separator housing 12, and this application does not impose any restrictions on this.

[0042] In some further embodiments, the first rib 125 includes a first side 1251 and a second side 1252 facing away from each other. The first side 1251, the inner wall of the first groove 124 and the stationary vortex disk 32 define the oil outlet channel 16 described above. The second side 1252, the inner wall of the first groove 124 and the stationary vortex disk 32 define the oil storage cavity 123 described above. One end of the first rib 125 is spaced apart from the inner wall of the first groove 124 to define an oil outlet 162.

[0043] In this embodiment, the structure of the first rib 125 is simple, and the formation of the oil outlet 162 is simple, which reduces the difficulty of mold opening of the oil separator shell 12 and reduces the cost of the horizontal scroll compressor 100.

[0044] In some specific embodiments, the inner wall of the first groove 124 includes a front inner wall 1242 and a side inner wall 1243, wherein the front inner wall 1242 is disposed directly opposite to the stationary vortex disk 32, and the side inner wall 1243 is disposed around the front inner wall 1242, and the side inner wall 1243 is connected to the front inner wall 1242 and extends toward the stationary vortex disk 32.

[0045] The first rib 125 is located inside the first groove 124. The side of the first rib 125 facing the inner wall 1242 is connected to the inner wall 1242. The side of the first rib 125 away from the inner wall 1242 abuts against the stationary vortex plate 32. One end of the first rib 125 is connected to the side inner wall 1243, and the other end of the first rib 125 is spaced apart from the side inner wall 1243.

[0046] An oil outlet channel 16 is defined between the first side surface 1251 of the first rib 125, a portion of the inner wall 1242, a portion of the inner wall 1243, and the stationary vortex disk 32. The portion of the inner wall 1242 defining the oil outlet channel 16 is provided with the aforementioned oil inlet 161, which communicates with the oil drain hole 1222 of the oil separator chamber 122. The oil outlet 162 is formed between the end of the first rib 125 spaced apart from the inner wall 1243 and the inner wall 1243. An oil storage chamber 123 is defined between the second side surface 1252 of the first rib 125, a portion of the inner wall 1242, a portion of the inner wall 1243, and the stationary vortex disk 32.

[0047] Reference Figure 2 , Figure 3 and Figure 4 In some specific embodiments, the portion of the stationary scroll 32 that defines the oil storage chamber 123 is provided with an oil return hole 322 that communicates with the oil storage chamber 123. The oil return hole 322 is located at the bottom of the oil storage chamber 123. The refrigerant oil in the oil storage chamber 123 can enter the oil return channel 323 through the oil return hole 322, thereby lubricating the friction pairs in the horizontal scroll compressor 100.

[0048] In some embodiments, the oil outlet 162 is oriented upwards to prevent the refrigerant oil discharged from the oil outlet 162 from directly impacting the existing refrigerant oil in the oil storage chamber 123, thereby improving the stability of the refrigerant oil in the oil storage chamber 123. In other embodiments, the oil outlet 162 may also be oriented downwards or at other angles.

[0049] In some embodiments, the first rib 125 is formed as an arc-shaped rib extending toward the first communication opening 1241.

[0050] Through the above technical solution, the oil outlet channel 16 is formed into an arc-shaped channel. When the refrigeration oil flows in the oil outlet channel 16, it will hit the bent first rib 125, increasing the flow resistance of the refrigeration oil and further reducing the flow rate and pressure of the refrigeration oil.

[0051] It should be understood that in other embodiments, the first rib 125 may also be a long strip, an S-shape, or other shapes, and this application does not limit this.

[0052] Reference Figure 3 In some embodiments, the thickness of the first rib 125 is T, where T ≥ 1.5 mm.

[0053] The above technical solution ensures that the first rib 125 has sufficient strength, reduces the risk of breakage of the first rib 125, reduces the risk of refrigerant oil leakage from the oil outlet channel 16 from the damaged area, ensures the reliability of the oil outlet channel 16, and extends the service life of the horizontal scroll compressor 100. In some specific embodiments, the thickness T of the first rib 125 can be 1.5mm, 2mm, 2.5mm, or other dimensions.

[0054] In some embodiments, a reinforcing rib 1244 is provided in the first groove 124. The two ends of the reinforcing rib 1244 are connected to the first rib 125 and the inner side wall 1243, respectively. In the depth direction of the first groove 124, the length of the reinforcing rib 1244 is less than the depth of the first rib 125, so as to reduce the influence of the reinforcing rib 1244 on the flow of refrigeration oil.

[0055] The above technical solution improves the strength of the first rib 125 and reduces the risk of damage to the first rib 125.

[0056] In some further embodiments, the first side 1251 and the second side 1252 of the first rib 125 are both provided with reinforcing ribs 1244, which further improves the structural strength of the first rib 125.

[0057] In some specific embodiments, the reinforcing rib 1244 is disposed at one end of the first rib 125 near the oil outlet 162, which further improves the structural strength of the first rib 125.

[0058] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the static vortex disk 32 is provided with a connecting groove 324 on the side facing the oil separator housing 12, and the first connecting port 1241 is connected to the oil separator chamber 122 through the connecting groove 324.

[0059] In this embodiment of the application, the first connecting port 1241 refers to the portion of the opening of the first tank 124 that is away from the oil storage chamber 123. A portion of the connecting groove 324 is directly opposite the first connecting port 1241 so that the connecting groove 324 is connected to the first connecting port 1241. A portion of the connecting groove 324 extends to be directly opposite the oil separator chamber 122 so that the connecting groove 324 can be connected to the oil separator chamber 122, thereby enabling the first connecting port 1241 to be connected to the oil separator chamber 122 through the connecting groove 324.

[0060] In this embodiment, the connection between the first communication port 1241 and the oil separator 122 is simple, which reduces the production cost of the horizontal scroll compressor 100.

[0061] In some specific embodiments, the oil separator 122 is provided with a second communication port 1223 on the side facing the stationary vortex disk 32. The second communication port 1223 is directly opposite to the communication groove 324, so that the first communication port 1241 is connected to the oil separator 122.

[0062] In this embodiment, the refrigerant precipitated from the refrigeration oil discharged from the oil outlet 16 can sequentially pass through the first connecting port 1241, the connecting groove 324, and the second connecting port 1223 before entering the oil separator chamber 122, and then be discharged from the horizontal scroll compressor 100 through the refrigerant outlet 121.

[0063] In some embodiments, the inner wall of the first tank 124 is provided with an oil baffle 1245, which is located between the oil outlet 162 and the first connecting port 1241.

[0064] By blocking the oil baffle 1245, the risk of refrigeration oil flowing to the first connecting port 1241 is reduced, and the risk of refrigeration oil in the first tank 124 entering the oil distribution chamber 122 through the first connecting port 1241 is also reduced.

[0065] In some specific embodiments, the oil baffle 1245 is formed as a rib disposed on the first groove 124. A gap for refrigerant to pass through is provided between the oil baffle 1245 and the inner wall of the first groove 124.

[0066] The oil baffle 1245 in this embodiment has a simple structure, which reduces the cost of the horizontal scroll compressor 100.

[0067] In some embodiments, the inner wall of the first groove 124 is provided with an arc-shaped protrusion 1246, which is located between the oil baffle 1245 and the first communication port 1241.

[0068] In this embodiment, the protrusion 1246 can block the refrigeration oil passing through the oil baffle 1245 again, further reducing the risk of refrigeration oil entering the oil distribution chamber 122 through the first communication port 1241.

[0069] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the horizontal scroll compressor 100 includes: a housing 1, a drive mechanism 2, and a compression component 3.

[0070] The housing 1 includes a first housing 11 and an oil separator housing 12. The first housing 11 is provided with a bracket 111 and a crankshaft 112. The bracket 111 is fixed relative to the first housing 11, and the crankshaft 112 is located inside the first housing 11 and is rotatable relative to the first housing 11. The first housing 11 is provided with a first bearing 113 for supporting the crankshaft 112, and the bracket 111 is provided with a second bearing 114 for supporting the crankshaft 112. That is, one end of the crankshaft 112 is rotatably mounted on the first housing 11 via the first bearing 113, and the other end of the crankshaft 112 is rotatably mounted on the bracket 111 via the second bearing 114.

[0071] The drive mechanism 2 is disposed inside the first housing 11 and is located between the first bearing 113 and the second bearing 114. The drive mechanism 2 includes a stator 21 and a rotor 22. The stator 21 is disposed on the inner wall of the first housing 11, and the rotor 22 is sleeved on the crankshaft 112. The stator 21 and the rotor 22 are coupled together. When the drive mechanism 2 is working, the stator 21 drives the crankshaft 112 to rotate through the rotor 22, so that the crankshaft 112 can drive the rotating scroll 31 to rotate.

[0072] The compression component 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 111 facing away from the first housing 11 and is fixedly mounted relative to the support 111. 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 111. 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.

[0073] An eccentric sleeve 115 is provided at one end of the crankshaft 112 facing the moving scroll 31. The crankshaft 112 is adapted to drive the moving scroll 31 to rotate through the eccentric sleeve 115. A third bearing 116 is provided between the eccentric sleeve 115 and the moving scroll 31 so that the crankshaft 112 can drive the moving scroll 31 to perform a rotary translational motion relative to the stationary scroll 32.

[0074] The first housing 11 is provided with a refrigerant inlet 117, which is connected to the internal space of the first housing 11. The internal space of the first housing 11 is connected to the air intake of the compression chamber 33. The oil separator housing 12 is located on the side of the stationary scroll 32 away from the moving scroll 31. The oil separator housing 12 is provided with an oil separator chamber 122. The stationary scroll 32 is provided with an exhaust port 321 connected to the oil separator chamber 122. The oil separator housing 12 is also provided with a refrigerant outlet 121 connected to the oil separator chamber 122. The refrigerant in the compression chamber 33 can enter the oil separator chamber 122 through the exhaust port 321 and then be discharged through the refrigerant outlet 121.

[0075] When the horizontal scroll compressor 100 is working, the stator 21 drives the crankshaft 112 to rotate through the rotor 22. The crankshaft 112 drives the moving scroll 31 to rotate and translate relative to the stationary scroll 32 through the eccentric sleeve 115, so that the refrigerant can be compressed in the compression chamber 33. The refrigerant in the external working circuit is drawn into the internal space of the first housing 11 through the refrigerant inlet 117, and then drawn into the compression chamber 33 through the suction port for compression. The compressed high-pressure refrigerant enters the oil separator chamber 122 through the exhaust port 321, and then is discharged through the refrigerant outlet 121.

[0076] In some embodiments, the oil separator housing 12 is further provided with a second groove 126 on the side facing the stationary vortex disk 32. The second groove 126 is spaced apart from the first groove 124. A rectifier cavity 127 is defined between the second groove 126 and the stationary vortex disk 32. The portion of the stationary vortex disk 32 that is directly opposite to the second groove 126 is provided with an exhaust port 321 of the compression chamber 33, so that the rectifier cavity 127 can communicate with the compression chamber 33. The rectifier cavity 127 is also connected to the oil separator inlet 1221 of the oil separator cavity 122.

[0077] The compression chamber 33 can discharge a mixture of refrigerant and refrigeration oil through the exhaust port 321. The mixture of refrigerant and refrigeration oil enters the rectifier chamber 127 through the exhaust port 321, and then enters the oil separator chamber 122 through the oil separator inlet 1221 for separation. In this embodiment, the rectifier chamber 127 is adapted to buffer the mixture of refrigerant and refrigeration oil discharged from the compression chamber 33, thereby improving the efficiency of the oil separator chamber 122 in separating refrigerant and refrigeration oil.

[0078] In some further embodiments, the second connection port 1223 of the oil separator chamber 122 is located above the oil separator inlet 1221, which avoids the risk of the mixture of refrigerant and refrigeration oil entering the oil separator chamber 122 from the oil separator inlet 1221 passing through the second connection port 1223, thus ensuring the stability of the operation of the horizontal scroll compressor 100.

[0079] Other configurations and operations of the horizontal scroll compressor 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0080] The air conditioner according to the present invention includes the horizontal scroll compressor 100 described above.

[0081] According to the embodiment of the present invention, in the air conditioner, the refrigerant oil in the oil separator 122 of the horizontal scroll compressor 100 needs to pass through the oil outlet 16 to enter the oil storage chamber 123. Furthermore, the oil outlet 162 of the oil outlet 16 is located above the oil inlet 161, requiring the refrigerant oil to overcome gravity within the oil outlet 16 to enter the oil storage chamber 123. This effectively reduces the speed and pressure of the refrigerant oil flowing out of the oil outlet 162, thereby reducing the impact of the refrigerant oil entering the oil storage chamber 123 on the existing refrigerant oil in the oil storage chamber 123. The impact force improves the stability of the refrigerant oil in the oil storage chamber 123. The oil return hole 322 at the bottom of the oil storage chamber 123 can always be submerged in refrigerant oil, preventing refrigerant from leaking into the oil return channel 323 through the oil return hole 322. This improves the cooling efficiency of the horizontal scroll compressor 100 and ensures sufficient oil return, allowing the friction pairs of the horizontal scroll compressor 100 to be effectively lubricated, improving the compression efficiency of the horizontal scroll compressor 100 and extending its service life. Furthermore, the oil outlet channel 16 is defined by the first rib 125, the inner wall of the first groove 124, and the stationary scroll 32. The inner wall of the oil outlet channel 16 has sufficient strength, reducing the risk of damage to the oil outlet channel 16 and the risk of refrigerant oil leakage from the damaged area. This ensures the reliability of the oil outlet channel 16, extends the service life of the horizontal scroll compressor 100, and guarantees the reliability of the air conditioner.

This means that the refrigerant oil needs to overcome gravity within the oil outlet 16 to enter the oil storage chamber 123, effectively reducing the speed and pressure of the refrigerant oil flowing out of the oil outlet 162, thereby reducing the impact of the refrigerant oil entering the oil storage chamber 123 on the existing refrigerant oil in the oil storage chamber 123. The impact force improves the stability of the refrigerant oil in the oil storage chamber 123. The oil return hole 322 at the bottom of the oil storage chamber 123 can always be submerged in refrigerant oil, preventing refrigerant from leaking into the oil return channel 323 through the oil return hole 322. This improves the cooling efficiency of the horizontal scroll compressor 100 and ensures sufficient oil return, allowing the friction pairs of the horizontal scroll compressor 100 to be effectively lubricated, improving the compression efficiency of the horizontal scroll compressor 100 and extending its service life.
