Description

Technical Field

[0001] The present application relates to the field of compressors, and in particular to a scroll compressor and an air-conditioning system. Background Art

[0002] This section is intended to provide background information relevant to understanding the various technologies described herein. As implied by the title of this section, this is a discussion of related technologies that should not in any way imply that they are necessarily prior art. Therefore, it should be understood that any statement in this section should be read from this perspective, rather than any admission of prior art.

[0003] Scroll compressors have been widely used in the fields of refrigeration systems, air conditioning systems, etc. In some technical solutions of scroll compressors, the oil-gas mixture enters the end cover from the air outlet of the scroll assembly, and an oil-gas separation device is configured in the end cover. After the oil-gas mixture enters the oil-gas separation device, it is separated into refrigerant gas and lubricating oil. The refrigerant gas is discharged from the compressor, and the lubricating oil enters the compressor again through the throttling channel to lubricate the various components of the compressor.

[0004] The oil-gas separation device is very important for the scroll compressor and the system where the scroll compressor is located. If there is no oil-gas separation device, a large amount of lubricating oil will enter the refrigeration system or air-conditioning system along with the refrigerant, which will reduce the heat exchange efficiency of the entire system. In addition, the large loss of lubricating oil will increase the wear of the scroll compressor parts due to lack of oil, thus causing the compressor to fail. However, the use of the oil-gas separation device will increase the cost of the scroll compressor.

[0005] Therefore, a scroll compressor is needed that can save costs and realize the oil-gas separation function. Utility Model Content

[0022] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present application, rather than to limit the scope of protection of the present application.

[0023] Figure 1 FIG. 2 shows a cross-sectional schematic diagram of a scroll compressor of the present application. Figure 1 As shown, the scroll compressor 100 is an electric scroll compressor, including a motor 3, a scroll assembly and a housing 8. The scroll assembly includes a fixed scroll 201 and a movable scroll 202. The motor 3 includes a drive shaft 4, and the drive shaft 4 has an eccentric pin 6 at one end close to the scroll assembly. The eccentric pin 6 is eccentric relative to the central axis of the drive shaft 4. The eccentric pin 6 is fitted in the eccentric block 5, and the eccentric block 5 is used to offset the centrifugal force caused by the rotational movement of the movable scroll 202. The movable scroll 202 is arranged between the eccentric block 5 and the fixed scroll 201. The movable scroll 202 and the fixed scroll 201 are arranged to engage with each other, leaving a small gap in the axial and radial directions to form a compression chamber 203. The motor 3, the drive shaft 4, the eccentric pin 6, the eccentric block 5 and other components are arranged in the housing 8.

[0024] The electric scroll compressor 100 further includes an end cover 1 , and the fixed scroll 201 is disposed between the housing 8 and the end cover 1 , and is connected to the housing 8 and the end cover 1 by, for example, bolts.

[0025] When the electric scroll compressor 100 is working, the motor 3 drives the movable scroll 202 through the connection of the drive shaft 4, the eccentric pin 6, the eccentric block 5 and the bearing 7, so that the movable scroll 202 rotates, thereby causing relative movement with the fixed scroll 201, and the volume of the compression chamber 203 between the movable scroll 202 and the fixed scroll 201 is reduced, and the refrigerant gas is introduced into the compression chamber 203 for compression. The compressed refrigerant gas includes lubricating oil gas, and the oil-gas mixture is discharged from the air outlet 21 of the fixed scroll 201 into the end cover 1. After oil and gas separation, the separated lubricating oil returns to the scroll assembly through the throttling channel 22 and other oil supply passages on the fixed scroll 201 to lubricate mechanical parts such as bearings and motors, thereby increasing the efficiency and service life of the electric scroll compressor.

[0026] Although Figure 1 Although not shown in the figure, the outlet 100B of the electric scroll compressor is connected to the condenser through a pipeline, and the condenser is connected to the expansion valve through a pipeline, and the expansion valve is connected to the evaporator through a pipeline. The evaporator is connected to the inlet 100A of the electric scroll compressor through a pipeline. The electric scroll compressor, the evaporator, the expansion valve and the condenser cooperate to form a refrigeration circuit of the vehicle air conditioner. The separated refrigerant gas returns to the inlet 100A from the outlet 100B to complete the recycling.

[0027] If the refrigerant gas is mixed with too much lubricating oil in the refrigeration circuit, the lubricating oil will adhere to the surface of the evaporator and condenser, thereby reducing the heat exchange efficiency of the evaporator and condenser, and thus causing the entire refrigeration system to be inefficient. In addition, excessive lubricating oil circulates with the refrigerant gas, and mechanical parts such as motors and bearings will fail due to lack of sufficient lubricating oil. Therefore, in order to improve the refrigeration efficiency and increase the safety and life of the compressor operation, the refrigerant and lubricating oil must be separated and returned to their respective positions after the oil-gas mixture is discharged from the fixed scroll disk 201.

[0028] Figure 2 FIG. 1 is a three-dimensional schematic diagram of the end cover 1 of the electric compressor 100 of the present application. Figure 1 and Figure 2 As shown, the end cover 1 is generally cup-shaped, including an end plate 15 and a side wall 16 connected to the edge of the end plate 15, and the end plate 15 and the side wall 16 surround a cavity. When the electric scroll compressor 100 is in operation, the oil-gas mixture enters the cavity. The outlet 100B of the electric scroll compressor 100 is set on the side wall 16, and the separated refrigerant gas enters the refrigeration circuit from the outlet 100B.

[0029] like Figure 2 As shown, the end cover 1 further includes a first partition 11, a second partition 12, a third partition 13 and a fourth partition 14. The first partition 11, the second partition 12, the third partition 13 and the fourth partition 14 are arranged in a cavity surrounded by the end plate 15 and the side wall 16, and are all connected to the end plate 15. In some embodiments, the first partition 11 is a door shape, and the second partition 12, the third partition 13 and the fourth partition 14 are a straight shape.

[0030] In some embodiments, the first partition 11 and the second partition 12 are connected and together with a portion of the end plate 15 form an air inlet chamber 101. The air inlet chamber 101 is connected to the air outlet 21 of the fixed scroll plate 201, and the oil-gas mixture enters the air inlet chamber 101 from the air outlet 21.

[0031] The third partition plate 13 connects the side wall 16 and the first partition plate 11, so a portion of the first partition plate 11, a portion of the second partition plate 12, a portion of the side wall 16, a portion of the end plate 15 and the third partition plate 13 form a first oil separation chamber 102a.

[0032] The fourth partition plate 14 connects the side wall 16 and the first partition plate 11, so a portion of the first partition plate 11, a portion of the second partition plate 12, a portion of the side wall 16, a portion of the end plate 15 and the fourth partition plate 14 form a second oil separation chamber 102b.

[0033] The second partition plate 12, a portion of the side wall 16 and a portion of the end plate 15 form an oil storage chamber 103 for storing lubricating oil after oil-gas separation.

[0034] The third partition plate 13, the fourth partition plate 14, a portion of the first partition plate 11, a portion of the end plate 15, and a portion of the side wall 16 form an exhaust chamber 104, and the exhaust chamber 104 is connected to the outlet 100B.

[0035] In some embodiments, the first partition plate 11 includes at least one first air inlet cavity opening 111 and at least one second air inlet cavity opening 112. The air inlet cavity 101 is connected to the first oil separation cavity 102a through the first air inlet cavity opening 111, and is connected to the second oil separation cavity 102b through the second air inlet cavity opening 112. After the oil-gas mixture enters the air inlet cavity 101, it enters the first oil separation cavity 102a and the second oil separation cavity 102b from the first air inlet cavity opening 111 and the second air inlet cavity opening 112, respectively.

[0036] In some embodiments, the third partition 13 includes at least one third opening 131, and the first oil separation chamber 102a is connected to the exhaust chamber 104 through the at least one third opening 131. The refrigerant gas after oil and gas separation in the first oil separation chamber 102a enters the exhaust chamber 104 through the at least one third opening 131.

[0037] In some embodiments, the fourth partition 14 includes at least one fourth opening 141, and the second oil separation chamber 102b is connected to the exhaust chamber 104 through the at least one fourth opening 141. The refrigerant gas after oil and gas separation in the second oil separation chamber 102b enters the exhaust chamber 104 through the at least one fourth opening 141.

[0038] In some embodiments, the second partition plate 12 includes at least one first oil storage chamber opening 121 and at least one second oil storage chamber opening 122. The first oil separation chamber 102a is connected to the oil storage chamber 103 through the first oil storage chamber opening 121, and the lubricating oil after oil-gas separation in the first oil separation chamber 102a flows into the oil storage chamber 103 through the first oil storage chamber opening 1021. The second oil separation chamber 102b is connected to the oil storage chamber 103 through the second oil storage chamber opening 122, and the lubricating oil after oil-gas separation in the second oil separation chamber 102b flows into the oil storage chamber 103 through the second oil storage chamber opening 1022.

[0039] The end cover 1 , that is, the cavity enclosed by the end plate 15 and the side wall 16 , is divided into an air intake cavity 101 , a first oil separation cavity 102 a , a second oil separation cavity 102 b , an exhaust cavity 103 and an oil storage cavity 104 .

[0040] When the oil-gas mixture enters the air inlet chamber 101, a turbulence phenomenon will be formed in the process of entering the first oil separation chamber 102a and the second oil separation chamber 102b from at least one first air inlet chamber opening 111 and at least one second air inlet chamber opening 121 respectively, causing the flow rate of the oil-gas mixture to change, thereby forming stratification. The gaseous refrigerant is located at the top, and the lubricating oil is located at the bottom. The lubricating oil will adhere to the walls of each cavity of the end cover 1, and due to gravity, it will flow along the walls and through at least one first oil storage chamber opening 121 and at least one second oil storage chamber opening 122 to the oil storage chamber 103.

[0041] When the oil-gas mixture enters the air intake chamber 101 from the vortex assembly, turbulence will also be formed. A portion of the lubricating oil will be separated and stored in the air intake chamber 101. When the lubricating oil accumulates to a certain amount, it will overflow from at least one first air intake chamber opening 111 and at least one second air intake chamber opening 121 to the corresponding first oil separation chamber 102a and second oil separation chamber 102b, and flow to the oil storage chamber 103 through at least one first oil storage chamber opening 121 and at least one second oil storage chamber opening 122.

[0042] When the gas flows from the first oil separation chamber 102a and the second oil separation chamber 102b through at least one third opening 131 and at least one fourth opening 141 to the exhaust chamber 104, turbulence will also be further formed, which can further achieve oil-gas separation, so that the refrigerant gas contains as little lubricating oil as possible, and as much lubricating oil as possible is separated and retained in the scroll compressor to lubricate various components.

[0043] In some embodiments, the size of the third opening 131 is smaller than the first oil storage chamber opening 121. For the gas, a larger opening size means a smaller flow resistance. Therefore, the gas in the first oil separation chamber 201a will flow more to the exhaust chamber 104 through the third opening 131, and the separated lubricating oil will flow into the oil storage chamber 103 through the first oil storage chamber opening 121.

[0044] Likewise, in some embodiments, the size of the fourth opening 141 is smaller than the second oil storage chamber opening 122 , and more gas in the second oil separation chamber 201 b will flow toward the exhaust chamber through the fourth opening 141 .

[0045] The end cover 1 is formed in one piece from aluminum alloy, that is, the end plate 15, the side wall 16, the first partition plate 11, the second partition plate 12, the third partition plate 13 and the fourth partition plate 14 are formed in one piece.

[0046] The end cover 1 of this embodiment forms different cavities by setting a plurality of partitions, so that the oil and gas mixture can be separated from each other in the process of flowing between different cavities, thereby optimizing the gas flow path, improving the compression efficiency of the compressor, improving the refrigeration efficiency of the refrigeration circuit, and improving the performance and life of the scroll compressor. At the same time, because a plurality of oil separation cavities are set, the efficiency of oil and gas separation is better improved. In addition, the function of oil and gas separation is realized by the design of the end cover itself, and there is no need to purchase and install an additional oil separator, thus saving costs.

[0047] Figure 3 FIG. 1 is a schematic diagram showing another embodiment of the end cover 1 of the electric compressor 100 of the present application. Figure 3 As shown, and Figure 2 Compared with the above, the end cover 1 includes a first partition plate 11, a second partition plate 12 and a third partition plate 13, and the fourth partition plate 14 is eliminated. The first partition plate 11, the second partition plate 12 and the side wall 16 form an air intake chamber 101; the first partition plate 11, the second partition plate 12, the third partition plate 12 and the side wall 16 form an oil separation chamber 102; the first partition plate 11, the third partition plate 13 and the side wall 16 form an exhaust chamber 104; the second partition plate 12 and the side wall 16 form an oil storage chamber 103. The air intake chamber 101 is connected to the oil-gas separation chamber 102 through an opening provided on the first partition plate 11, the oil-gas separation chamber 102 is connected to the oil storage chamber 103 through an opening provided on the second partition plate 12, and the oil-gas separation chamber 102 is connected to the exhaust chamber 104 through an opening provided on the third partition plate 13. In this embodiment, the oil-gas mixture enters the air inlet chamber 101 from the air outlet 21, and then enters the oil separation chamber 102 from the air inlet chamber 101. The refrigerant gas after the oil-gas mixture is separated enters the exhaust chamber 104, and the lubricating oil after the oil-gas mixture is separated enters the oil storage chamber 103 along the gravity direction. The flow velocity of the oil-gas mixture changes when it flows between different chambers, so that the refrigerant gas and the lubricating oil are separated, and the separated lubricating oil flows along the wall to the oil storage chamber due to gravity.

[0048] In some embodiments of the present application, openings are provided on the first partition 11, the second partition 12, the third partition 13 and / or the fourth partition 14 to facilitate communication between the various chambers, and the openings mentioned here include holes and cavities of different shapes and sizes.

[0049] like Figure 1 As shown, in some embodiments, the electric scroll compressor further includes a filter 9, which is arranged upstream of the throttling channel 22 along the flow direction of the lubricating oil and is located in the oil storage chamber, and the filter is used to filter the lubricating oil particles. The setting of the filter can avoid or alleviate the oil particles blocking the throttling channel, thereby improving the reliability of the operation of the electric scroll compressor.
