Description

Technical Field

[0001] This application relates to the field of compression technology, and particularly to a compressor, an air conditioner, and a vehicle. Background Art

[0002] An electric scroll compressor realizes the compression of refrigerant gas by driving a moving disk to rotate relative to a stationary disk. The stationary disk is provided with an exhaust port, and the oil-gas mixture enters the oil separation chamber through the exhaust port. In the oil separation chamber, it acts on the oil-gas separator to separate oil and gas.

[0038] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0039] As Figure 1 shown, the compressor includes a housing 10, and various components of the compressor are installed inside the housing 10, such as bearings, a rotating disk 53, a stationary disk 51, etc. The compressor in the embodiment of the present application can be an electric scroll compressor, and the electric scroll compressor drives the rotating disk 53 to rotate through a motor to achieve gas compression. The rotating disk 53 and the stationary disk 51 can be set with a phase angle difference of 180°, and the rotating disk 53 and the stationary disk 51 are oppositely installed in the compression chamber 13. The driving shaft 60 drives the rotating disk 53 to move, and the rotating disk 53 meshes with the stationary disk 51 to form a series of crescent-shaped working chambers 131 that are isolated from each other and have continuously changing volumes. When the compressor operates, the power component 70 drives the driving shaft 60 to rotate, and the crank of the driving shaft 60 drives the rotating disk 53 to move. Under the anti-self-rotation restriction of the limiting member, the rotating disk 53 makes a translational motion around the center of the driving shaft 60 with a fixed radius, thereby compressing the oil-gas mixture. It is easy to understand that the oil-gas mixture is a mixture of refrigerant and lubricating oil, and the refrigerant in the compressor is in a gaseous state.

[0040] The stationary disk 51 is provided with an exhaust port, and the oil-gas mixture enters the oil separation chamber 11 through the exhaust port. In the oil separation chamber 11, it acts on the oil-gas separator 30 to perform oil-gas separation. Especially when the compressor operates at a low speed, due to the small mass flow rate of the refrigerant and the low oil content rate, a more efficient oil-gas separation structure is required to meet the lubricating oil amount required by the compressor.

[0041] In the related art, the end face at the bottom of the oil-gas separator is usually set as a continuous plane, and large drops of oil are likely to adhere to this plane, so that there is a large interaction force between the oil drops and the end face at the bottom of the oil-gas separator, and the large drops of oil are not easily separated from the end face at the bottom of the oil-gas separator, resulting in poor oil separation efficiency.

[0042] In the embodiment of the present application, the oil-gas separator 30 is provided to increase the contact area between the oil-gas mixture and the oil-gas separator 30, and the bottom of the oil-gas separator 30 can be designed to be a sawtooth shape to meet the lubrication requirements of the compressor.

[0043] Please combine Figure 2 and Figure 3 In the embodiment of the present application, the compressor includes a housing 10 and an oil-gas separator 30, the housing 10 is formed with an oil separation chamber 11, and the oil-gas separator 30 is installed in the oil separation chamber 11. Specifically, the housing 10 may include a main body 101 and an end cover 103, the end cover 103 is connected to one end of the main body 101, and the end cover 103 is provided with the oil separation chamber 11. The oil-gas separator 30 may specifically be a cyclone separator.

[0044] The oil-gas separator 30 includes an exhaust portion 31 and a plurality of teeth 33 . Along the gravity direction, the exhaust portion 31 includes a first end 311 and a second end 313 that are oppositely disposed. The first end 311 is close to the top of the housing 10 .

[0045] The exhaust portion 31 is provided with an exhaust cavity 314 penetrating the first end 311 and the second end 313 . The second end 313 is provided with a plurality of teeth 33 . The plurality of teeth 33 can extend toward the cavity wall of the oil separation cavity 11 and be spaced apart from the cavity wall.

[0046] The oil separation chamber 11 can extend in the direction of gravity, and the top of the housing 10 is provided with an air outlet 12 connected to the oil separation chamber 11. The separated airflow discharged from the compressor through the air outlet 12 of the housing 10 can continue to participate in the refrigeration cycle of the air conditioner. The first end 311 is specifically arranged close to the air outlet 12.

[0047] The plurality of teeth 33 extend in a direction away from the first end 311. The airflow with a lower oil content after one separation enters the oil-gas separator 30 from the second end 313 of the exhaust portion 31, and can pass through the exhaust cavity 314 and the first end 311 in sequence and then be discharged from the compressor from the air outlet 12 of the housing 10. The separated airflow discharged from the compressor from the air outlet 12 of the housing 10 can continue to participate in the refrigeration cycle of the air conditioner. The ends of two adjacent teeth 33 away from the exhaust portion 31 are spaced apart.

[0048] The oil-gas mixture enters the oil separation chamber 11, and in the oil separation chamber 11, it interacts with the oil-gas separator 30 to separate the oil and gas. The separated gas is discharged from the gas outlet 12, and due to gravity, the separated oil falls to the bottom of the oil separation chamber 11. The multiple teeth 33 extend in a direction away from the first end 311, so that the multiple teeth 33 are hollowed out. Therefore, the oil droplets attached to the multiple teeth 33 are smaller, the interaction force between the oil and the end surface of the bottom of the oil-gas separator 30 is smaller, the oil droplets are easily separated from the end surface of the bottom of the oil-gas separator 30, and the oil separation efficiency is high.

[0049] Please combine with Figure 3 and Figure 4 In some embodiments, along the direction from the first end 311 to the second end 313, the cross-sectional area of the tooth part 33 gradually decreases. In these embodiments, as it is farther away from the exhaust part 31, the cross-sectional area of the tooth part 33 gradually decreases. The oil droplets can quickly drip from the tooth part 33 and separate from the end face at the bottom of the oil-gas separator 30, improving the oil separation efficiency.

[0050] Specifically, along the direction of gravity, the cross-sectional shape of the tooth part 33 is triangular, semi-circular or trapezoidal. In this way, it is realized that as it is farther away from the exhaust part 31, the cross-sectional area of the tooth part 33 gradually decreases.

[0051] In this way, it can overcome the situation of large surface tension in the flat-bottom design, so that the oil droplets can quickly leave the oil-gas separator 30. At the same time, the oil-gas separator 30 can be designed to be longer, and the oil-gas separation effect is better. The oil-gas separator 30 is designed to be longer, which can increase the contact area between the oil-gas mixture and the oil-gas separator 30 and increase the oil separation rate. Since the end parts of two adjacent tooth parts 33 facing away from the exhaust part 31 are arranged at intervals, the pressure loss caused by the too-close distance between the lower end of the oil-gas separator 30 and the cavity wall of the oil separation cavity 11 can be reduced.

[0052] Please combine with Figure 3 and Figure 4 In some embodiments, a concave part 34 is formed between two adjacent tooth parts 33. The end parts of two adjacent tooth parts 33 facing away from the exhaust part 31 are arranged at intervals from the cavity wall of the oil separation cavity 11, and at least part of the interval between the concave part 34 and the cavity wall of the oil separation cavity 11 is greater than the interval between the tooth part 33 and the cavity wall of the oil separation cavity 11.

[0053] Compared with the scheme in the related art of setting the end face at the bottom of the oil-gas separator as a plane, in the embodiments of the present application, the interval between the concave part 34 and the cavity wall is larger, and the oil-gas mixture has a larger flow-through area, so that when it enters the oil return cavity 15 through the oil-gas separator 30, it has a smaller pressure loss.

[0054] Please combine with Figure 1 In some embodiments, the housing 10 forms a compression cavity 13. The arrangement direction of the compression cavity 13 and the oil separation cavity 11 is perpendicular to the direction of gravity. The housing 10 is provided with a first through hole (not shown in the figure) for communicating the compression cavity 13 and the oil separation cavity 11; the compressor further includes a compression assembly 50, and the compression assembly 50 is installed in the compression cavity 13. The oil-gas mixture compressed by the compression assembly 50 enters the oil separation cavity 11 through the first through hole, and the first through hole can be located between the first end 311 and the second end 313.

[0055] In these embodiments, the first through-hole is located between the first end 311 and the second end 313. The oil-gas mixture compressed by the compression assembly 50 enters the oil separation chamber 11 through the first through-hole. The oil-gas mixture entering the oil separation chamber 11 from the first through-hole on the side of the compressor oil separation chamber 11 flows in a swirling direction around the exhaust portion 31. The strong centrifugal force causes the liquid particles in the mixture to be thrown off and accumulate on the outer wall of the exhaust portion 31, and finally fall to the bottom of the oil separation chamber 11, enabling sufficient oil-gas separation.

[0056] Please refer to Figure 1 , in some embodiments, the compression chamber 13 includes a working chamber 131 and a high-pressure chamber 133. The compression assembly 50 includes a stationary disk 51 and a rotating disk 53 that are meshed. The stationary disk 51 and the rotating disk 53 form the working chamber 131. The stationary disk 51 is provided with an exhaust hole. The side of the stationary disk 51 facing away from the rotating disk 53 forms the high-pressure chamber 133 with the housing 10. The working chamber 131 communicates with the high-pressure chamber 133 through the exhaust hole, and the high-pressure chamber 133 communicates with the oil separation chamber 11 through the first through-hole.

[0057] In these embodiments, the oil-gas mixture enters the working chamber 131 between the stationary disk 51 and the rotating disk 53 and is compressed. A small amount of oil forms an oil film for lubricating and sealing the profiles of the rotating disk 53 and the stationary disk 51. After most of the oil is compressed, it enters the high-pressure chamber 133 and then enters the oil separation chamber 11 through the first through-hole for oil-gas separation.

[0058] In some embodiments, an air inlet is provided at one end of the housing 10 away from the oil-gas separator 30. The housing 10 is further provided with a power chamber 14 communicated with the air inlet. The power chamber 14 is located on the side of the compression chamber 13 facing away from the oil separation chamber 11. The oil-gas mixture enters the power chamber 14 through the air inlet. The compressor further includes a power assembly 70 installed in the power chamber 14. The power assembly 70 includes a stator assembly 71 and a rotor assembly 73. A first flow channel communicated with the power chamber 14 is formed between the stator assembly 71 and the housing 10, and a second flow channel communicated with the power chamber 14 is formed between the stator assembly 71 and the rotor assembly 73. Both the first flow channel and the second flow channel communicate with the working chamber 131. In these embodiments, the oil-gas mixture enters the power chamber 14 through the air inlet, enters the first flow channel and the second flow channel, and cools and lubricates the stator assembly 71 and the rotor assembly 73.

[0059] In some embodiments, the housing 10 is further provided with an oil return chamber 15. The oil return chamber 15 communicates with the oil separation chamber 11 and is located on the side of the oil separation chamber 11 facing away from the air outlet 12. The oil return chamber 15 communicates with the compression chamber 13. In these embodiments, after the lubricating oil separated from the oil separation chamber 11 enters the oil return chamber 15, it enters the compression chamber 13 to lubricate and seal the compression assembly 50.

[0060] Please refer to Figure 1 and Figure 5, in some embodiments, the housing 10 is formed with a bearing cavity 16, and the bearing cavity 16 is located between the oil return cavity 15 and the power cavity 14. The compressor further includes a throttle valve 90. One end of the throttle valve 90 faces the oil return cavity 15, and the other end faces the bearing cavity 16. The oil in the oil return cavity 15 enters the bearing cavity 16 after being depressurized by the throttle valve 90.

[0061] In these embodiments, by providing the throttle valve 90, the oil (refrigerant oil) can flow back to the bearing cavity 16 with a lower pressure, ensuring the lubrication and sealing of the bearing. Among them, the inner diameter of the capillary 91 of the throttle valve 90 can be 0.2 - 0.3 mm, for example: 0.2 mm, 0.25 mm, 0.3 mm, and the length can be 20 - 25 mm, for example: 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 24.5 mm, 25 mm. In this way, it has a better pressure reduction effect.

[0062] The steps of oil - gas separation are as follows:

[0063] On the first hand, an inlet is provided on the side of the oil - separation cavity 11. The oil - gas mixture enters the oil - separation cavity 11 from the first through - hole and acts on the oil - gas separator 30. The specific way is: the oil - gas mixture flows in a swirling direction around the exhaust part 31 of the oil - gas separator 30. The strong centrifugal force causes the liquid particles in the mixture to be thrown off and gather on the outer wall of the exhaust part 31, and finally fall to the bottom of the oil - separation cavity 11. At this time, the outer wall of the exhaust part 31 forms a first oil path for downward backflow, and the first - stage oil - gas separation is carried out here.

[0064] On the second hand, the gas flow with a lower oil - content rate after the first - stage separation enters the oil - gas separator 30 from the second end 313 of the exhaust part 31, and can sequentially pass through the exhaust cavity 314 and the first end 311 and then be discharged from the air outlet 12 of the housing 10 out of the compressor. The separated gas flow discharged from the air outlet 12 of the housing 10 can continue to participate in the refrigeration cycle of the air conditioner. During the process of flowing out along the second end 313, the exhaust cavity 314, the first end 311, and the air outlet 12, there is still some oil in the gas flow. Because the density of the oil is large and the density of the gas is small, the oil droplets adhere to the inner wall of the exhaust cavity 314 and fall due to gravity during the upward flow of the oil - gas mixture, separating from the gas and flowing out of the oil - gas separator 30 from the second end 313, and the second - stage oil - gas separation is carried out.

[0065] In an embodiment of the present application, the power component 70 can be a motor. The low-temperature and low-pressure oil-gas mixture enters the housing 10 to cool the inner wall surface of the housing 10. It passes through the first flow path between the cutting edge on the stator assembly 71 and the housing 10 and the air gap between the stator assembly 71 and the rotor assembly 73 to cool the power component 70, and then flows into the working chamber 131 formed by the scroll profiles of the stationary disk 51 and the rotating disk 53 through the channel on the housing 10. A part of the residual lubricating oil forms an oil film for lubricating and sealing the profiles of the rotating disk 53 and the stationary disk 51. Then, after the oil-gas mixture is compressed, it is discharged from the exhaust hole of the stationary disk 51 into the high-pressure chamber 133. Through the high-pressure chamber 133 formed by the back surface of the stationary disk 51 and the inner wall of the end cover 103 of the housing 10, the separated lubricating oil enters the oil separation chamber 11. Through the separation effect of the oil-gas separator 30, a part of the lubricating oil is separated and returns to the side of the stationary disk 51 facing away from the rotating disk 53 under the action of gravity to form an oil return chamber 15 with the end cover 103. The refrigerant gas and part of the unseparated lubricating oil are discharged from the compressor through the first end 311 and the air outlet 12 and continue to participate in the air-conditioning system cycle.

[0066] In an embodiment of the present application, the separated lubricating oil can be used to ensure the lubrication of the rotating components of the compressor and the oil film seal between the profiles of the stationary disk 51 and the rotating disk 53. Specifically, under the action of the oil-gas separator 30, the first part of the separated lubricating oil enters the oil separation chamber 11 under the action of gravity. The lubricating oil in the oil separation chamber 11 can enter the friction pair through the oil path to lubricate and seal the friction pair. The lubricating oil in the oil separation chamber 11 can also be depressurized through the throttle valve 90 and stored in the medium-pressure chamber 134 formed by closing the side of the rotating disk 53 facing away from the stationary disk 51 and the housing 10 to lubricate the bearing. Then, the lubricating oil is transported to the friction pair under the action of rotational movement and pressure. Part of the lubricating oil flows into the crescent chamber formed by the stationary disk 51 and the rotating disk 53 under the action of pressure, thereby sealing and lubricating the working chamber 131. Another part of the lubricating oil flows to the low-pressure chamber after being depressurized through the throttle valve 90 on the housing 10.

[0067] In an embodiment of the present application, by arranging the oil-gas separator 30 in the oil separation chamber 11, the oil-gas separation of the gas carrying part of the lubricating oil flowing through the oil-gas separator 30 can be realized, which is beneficial to increasing the oil return rate and reducing the oil discharge amount, and further ensuring the stable operation of the compressor. The oil droplets attached to the tooth part 33 are small droplets with a small windward area, which are not easily carried away by the oil-gas mixture and are more likely to drip onto the bottom of the oil separation chamber 11 under the action of gravity, having a better separation effect.

[0068] The material of the oil-gas separator 30 can be aluminum, iron, alloy or other materials. The matching method between the oil-gas separator 30 and the housing 10 is cold press fitting or hot sleeve fitting. The oil-gas separator 30 can be integrally formed during processing.
