Description

Technical Field

[0001] The present application relates to the technical field of mechanical equipment, and in particular to a working fluid output device, a thermal management system, and a vehicle. Background Art

[0002] For equipment such as scroll compressors that output a compressed medium (such as a refrigerant), a lubricating medium (such as lubricating oil) is generally mixed into the refrigerant so that the lubricating oil can be used to lubricate structures such as bearings, rotors, and stators during the circulation of the refrigerant, and the refrigerant can be used for cooling. In particular, for a scroll compressor, the moving disk rotates relative to the stationary disk, so that the volume of the chamber formed between the two changes to achieve pressurization of the refrigerant. At this time, the lubricating oil mixed in the refrigerant can also be used to lubricate the mating area between the two. This type of scroll compressor is widely used in vehicles and other equipment.

[0003] In related technologies, devices that output compressed medium often need to separate lubricating medium from the compressed medium when discharging it. This requires an "oil-gas separation" mechanism to retain the lubricating medium within the device for lubrication. Currently, this separation is typically achieved by installing an oil-gas separator (such as a cyclone separator) at the point where the compressed medium is discharged from the device. However, this separation is limited in effectiveness, resulting in high lubricant consumption during device use. Utility Model Content

[0080] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0081] According to the first aspect of this application, referring to Figures 1 to 8 The present application provides a working fluid output device 100. In some exemplary embodiments, the working fluid output device 100 of the present application may be a compressor. More specifically, the working fluid output device 100 may be a scroll compressor. For ease of description, the working fluid output device 100 will be referred to as a compressor hereinafter.

[0082] refer to Figure 1 , which is an overall schematic diagram of the compressor provided in this application, the compressor includes: a casing 101, a stator assembly 102, a rotor assembly 103, an electronic control assembly 104, a crankshaft 105, a magnetic ring 106, a magnetic mounting pin 107, a Hall chip 108, a moving plate 109, an eccentric sleeve 115, a stator plate 110, a first type bearing 111, a second type bearing 112, a third type bearing 113, and an end cover 114.

[0083] The housing 101 defines a receiving space 101a. The stator assembly 102 and the rotor assembly 103 are integrated within the receiving space 101a. The stator assembly 102 is fixedly connected to the housing 101, while the rotor assembly 103 is rotationally connected to the housing 101. The stator assembly 102 is electrically connected to the electronic control assembly 104, generating a varying magnetic field under the control of the electronic control assembly 104. The rotor assembly 103, situated within this varying magnetic field, rotates relative to the housing 101 due to the magnetic force. A crankshaft 105 is coaxially fixedly connected to the rotor assembly 103 to rotate synchronously with the rotor.

[0084] The magnetic ring 106 is coaxially fixedly connected to one end of the crankshaft 105 through a magnetic mounting pin 107, and rotates as the crankshaft 105 rotates. The Hall chip 108 is fixed in the housing 101, electrically connected to the electronic control assembly 104 and facing the magnetic ring 106. The Hall chip 108 is an electronic component that uses the Hall principle to detect the speed of moving parts, and its working principle is not described here. The Hall chip 108 is used to detect the rotational speed of the magnetic ring 106, and transmits a signal containing the rotational speed information of the magnetic ring 106 to the electronic control assembly 104 in the form of an electrical signal, thereby utilizing the cooperation of the Hall chip 108 and the magnetic ring 106 to feed back the rotational speed of the crankshaft 105 to the electronic control assembly 104, so that the electronic control assembly 104 can flexibly adjust the rotational speed of the crankshaft 105 as needed.

[0085] The movable plate 109 is connected to the other end of the crankshaft 105, allowing it to move with the rotation of the crankshaft 105. In a specific embodiment, the movable plate 109 is eccentrically arranged relative to the rotor assembly 103 via the crankshaft 105 and an eccentric sleeve 115, allowing the movable plate 109 to rotate eccentrically relative to the crankshaft 105 as the crankshaft 105 rotates. The eccentric sleeve 115 is arranged axially between the crankshaft 105 and the movable plate 109 to separate the crankshaft 105 and the movable plate 109 in the axial direction of the crankshaft 105 and provide a buffer when the movable plate 109 is subjected to axial loads. The stator plate 110 is fixedly arranged outside the casing 101 and is adjacent to the movable plate 109, thereby enclosing the movable plate 109 in the accommodating space 101a. Furthermore, the side of the rotating plate 109 away from the crankshaft 105 and the stator plate 110 enclose a pressurized chamber 109a. Pressurized chamber 109a can be used to accommodate a fluid (such as a refrigerant). Rotating the rotating plate 109 can increase the pressure of the fluid within chamber 109a by, for example, changing the volume of chamber 109a. The principle of pressurizing a fluid by cooperating with the stator plate 110 and the rotating plate 109 in a compressor is well known to those skilled in the art. This application does not involve improvements to this technology and will not be elaborated upon herein.

[0086] To ensure smooth rotation of the moving components in the housing 101, a third-type bearing 113 is specifically positioned on the end of the crankshaft 105 near the magnetic ring 106. The third-type bearing 113 is located between the housing 101 and the crankshaft 105. A second-type bearing 112 is also positioned between the crankshaft 105 and the housing 101. Along the axial direction of the crankshaft 105, the rotor is positioned between the second-type bearing 112 and the third-type bearing 113. The cooperation of the second-type bearing 112 and the third-type bearing 113 ensures stable rotation of the crankshaft 105 connected to the housing 101. A first-type bearing 111 is positioned between the rotating plate 109 and the crankshaft 105, ensuring that the crankshaft 105 can stably drive the rotating plate 109 to move, allowing the rotating plate 109 to move stably relative to the stator plate 110. In a more specific solution, the eccentric sleeve 115 can be sleeved on one end of the crankshaft 105 close to the moving plate 109 , and the first type bearing 111 is sleeved on the eccentric sleeve 115 .

[0087] refer to Figure 1 and Figure 2 In this application, an air inlet 101b is provided on the housing 101, and the air inlet 101b is connected to the accommodating space 101a. At the same time, the housing 101 is also provided with a through hole 109b that connects the boost chamber 109a and the accommodating space 101a. The air inlet 101b is connected to the through hole 109b through the accommodating space 101a, that is, the air inlet 101b can be connected to the boost chamber 109a, so that the air inlet 101b can be used to pass a fluid working medium into the boost chamber 109a. In order to achieve lubrication of each bearing, the fluid working medium entering the accommodating space 101a from the air inlet 101b is mixed with a lubricating medium (such as lubricating oil). For the convenience of explaining the concept of the present invention, the refrigerant is referred to as the fluid working medium and the lubricating oil is referred to as the lubricating medium in the following text.

[0088] As the refrigerant flows through the accommodating space 101a, the lubricating oil can contact and lubricate the various bearings. In some optional solutions, the stator assembly 102 and the rotor assembly 103 are spaced apart to form an air gap between them. When the fluid flows through the air gap, it lubricates the stator assembly 102 and the rotor assembly 103. Furthermore, the refrigerant flowing in the accommodating space 101a can be used to cool the stator assembly 102, the rotor assembly 103, and other structures.

[0089] The refrigerant enters the boost chamber 109a from the accommodating space 101a. After being compressed in the boost chamber 109a, it needs to enter the external pipeline for circulation to complete the cooling or heating of the outside world, while the lubricating oil in the fluid working medium should be retained more inside the compressor to lubricate the various components inside the compressor. Therefore, it is necessary to separate the lubricating oil from the refrigerant as much as possible, that is, the refrigerant needs to be subjected to an "oil-gas separation" operation. A "secondary oil-gas separation structure" is provided on the compressor of the present application to enhance the effect of oil-gas separation. The following is an exemplary description of the secondary oil-gas separation structure.

[0090] In some embodiments, reference Figure 4 and Figure 5 The end cap 114 is fixed to the side of the stator plate 110 away from the rotor plate 109, and the end cap 114 and the stator plate 110 together form a primary oil separation chamber 110a. The stator plate 110 is provided with an inlet 110b for introducing fluid into the primary oil separation chamber 110a. Specifically, the inlet 110b connects the boost chamber 109a and the primary oil separation chamber 110a, allowing the pressurized refrigerant to enter the primary oil separation chamber 110a. An oil return hole 110c is provided between the stator plate 110 and the end cap 114, communicating with the primary oil separation chamber 110a, and an oil return chamber 110d is provided, communicating with the primary oil separation chamber 110a through the oil return hole 110c. The oil return hole 110c is located below the primary oil separation chamber 110a, so that the lubricating medium mixed with the fluid in the primary oil separation chamber 110a flows to the oil return hole 110c under the action of gravity. Therefore, after the refrigerant enters the primary oil separation chamber 110a from the boosting chamber 109a, part of the lubricating oil flows to the oil return hole 110c under the action of gravity and enters the oil return chamber 110d, realizing the primary oil-gas separation.

[0091] On this basis, reference Figure 5 and Figure 6 The end cover 114 is provided with an air outlet 114a connected to the primary oil separation chamber 110a, and a secondary oil separation chamber 114b connected to the primary oil separation chamber 110a through the air outlet 114a, that is, in the present application, the secondary oil separation chamber 114b is connected to the primary oil separation chamber 110a. Therefore, the present application performs at least two oil-gas separations when outputting the fluid working medium, thereby improving the oil-gas separation effect. Specifically, the fluid working medium mixed with the lubricating medium undergoes two oil-gas separations in the primary oil separation chamber and the secondary oil separation chamber during the process of flowing out of the end cover. Compared with the conventional solution of only one oil-gas separation, more lubricating medium flows to the return oil chamber for the subsequent lubrication function, thereby improving the oil-gas separation effect and improving the effective utilization rate of the lubricating medium during the use of the equipment.

[0092] The air outlet 114a is used to connect the secondary oil separation chamber 114b with the primary oil separation chamber 110a, and the flow area of ​​the air outlet 114a can be made smaller than the flow areas of the secondary oil separation chamber 114b and the primary oil separation chamber 110a, so that the air flow flows from the primary oil separation chamber 110a to the air outlet 114a, and then the air flow is concentrated at the air outlet 114a and flows to the secondary oil separation chamber 114b, and diffuses in the secondary oil separation chamber 114b so that the air flow velocity is relatively slow, which facilitates the full separation of oil and gas.

[0093] In a specific embodiment, the diameter of the oil return hole 110c is smaller than that of the primary oil separation chamber 110a and smaller than that of the air outlet 114a. Therefore, after the majority of the refrigerant enters the primary oil separation chamber 110a from the boost chamber 109a, it enters the secondary oil separation chamber 114b through the air outlet 114a. The secondary oil separation chamber 114b is located above the primary oil separation chamber 110a. This allows the lubricating medium mixed with the fluid flowing from the primary oil separation chamber 110a to the secondary oil separation chamber 114b to flow toward the primary oil separation chamber 110a under the action of gravity. This ensures that the oil flows fully into the primary oil separation chamber 110a and reduces oil accumulation in the secondary oil separation chamber 114b. In this way, under the action of gravity, the lubricating oil mixed in the refrigerant entering the secondary oil separation chamber 114b flows back to the primary oil separation chamber 110a, and then flows from the oil return hole 110c to the oil return chamber 110d, realizing secondary oil and gas separation.

[0094] For specific solutions, refer to Figure 5 and Figure 6 An oil guide port 114c communicating between the secondary oil separation chamber 114b and the primary oil separation chamber 110a may be provided on the end cover 114 to allow the lubricating oil to flow back from the secondary oil separation chamber 114b to the primary oil separation chamber 110a.

[0095] In some embodiments, at least a portion of the inner wall of the end cap 114 forming the secondary oil separation chamber 114b is constructed as a revolving surface with the revolving axis 114d as the center line, and the angle α between the revolving axis 114d and the horizontal plane ranges from 0 to 180 degrees. Figure 6 The secondary oil separation chamber 114b can be constructed as a cylindrical hole formed on the end cover 114, or can be set as a combination of multiple cylindrical holes with different apertures in a stepped shape, and the lubricating oil can flow back to the primary oil separation chamber 110a along the hole wall of the cylindrical hole.

[0096] In some embodiments, the rotation axis 114d is arranged to be inclined upward from one end close to the air outlet 114a to one end away from the air outlet 114a. This arrangement helps the lubricating oil to flow back from the secondary oil separation chamber 114b to the primary oil separation chamber 110a.

[0097] In some embodiments, the working fluid output device 100 also includes: a cyclone separator. The cyclone separator is used to return part of the lubricating medium mixed with the fluid working fluid in the secondary oil separation chamber 114b to the oil return chamber 110d. The cyclone separator is provided with an air outlet channel for the discharge of the fluid working fluid, and the air outlet channel is connected to the secondary oil separation chamber 114b. The cyclone separator is fixedly connected to the end of the secondary oil separation chamber 114b away from the air outlet 114a, so that the lubricating oil separated by the cyclone separator flows back to the primary oil separation chamber 110a through the flow channel formed together with the end cover 114, so as to further improve the oil-gas separation effect. The cyclone separator and the flow channel formed by the cyclone separator and the end cover 114 are not shown in the accompanying drawings. This application does not involve improvements to the structure of the cyclone separator itself, and will not be elaborated here.

[0098] When a cyclone separator is provided, the refrigerant after oil and gas separation flows from the cyclone separator to a circulation pipeline outside the compressor, participating in cooling or heating the external environment.

[0099] In some embodiments, the entire structure, including the electronic control assembly 104, stator assembly 102, rotor assembly 103, crankshaft 105, second-type bearing 112, and third-type bearing 113, can serve as a driving member to move the movable plate 109 relative to the stator plate 110. Under the action of the driving member, the movable plate 109 cooperates with the stator plate 110 to increase the pressure of the refrigerant. The driving member can be at least partially disposed within the accommodation space 101a, so that the housing 101 can provide protection for the driving member.

[0100] In some embodiments, reference Figure 1 and Figure 3 The crankshaft 105, housing 101, and rotor plate 109 together form an assembly space 101c, in which the first-type bearing 111 is located. The stator plate 110 is provided with an oil return passage 110e connecting the assembly space 101c with an oil return chamber 110d. This allows lubricant in the oil return chamber 110d to flow from the oil return passage 110e into the assembly space 101c. This arrangement allows lubricant in the oil return chamber 110d to enter the assembly space 101c and lubricate the first-type bearing 111.

[0101] In some embodiments, the second type bearing 112 is located in the assembly space 101 c , so that lubricating oil entering the assembly space 101 c can lubricate the second type bearing 112 .

[0102] In some embodiments, a connecting channel is provided on the housing 101, and the assembly space 101c and the accommodating space 101a are connected through the connecting channel, so that lubricating oil can enter the accommodating space 101a through the connecting channel to lubricate components such as the third type bearing 113 in the accommodating space 101a. The connecting channel is not shown in the accompanying drawings.

[0103] In some embodiments, reference Figure 1 and Figure 7 The working fluid output device 100 further includes a throttle valve 116. The throttle valve 116 is disposed within the oil return channel 110e. The throttle valve 116 can be specifically configured as a capillary tube 116a. Specifically, the throttle valve 116 is provided with a capillary tube 116a, which connects the assembly space 101c and the oil return chamber 110d. The inner wall diameter of the capillary tube 116a can range from 0.2 to 0.3 mm, and the length can range from 20 to 25 mm. This allows the lubricating oil gathered in the oil return chamber 110d to become mist when flowing from the capillary tube 116a to the assembly space 101c, thereby improving the lubrication effect. The provision of the throttle valve 116 can also reduce the air pressure of the refrigerator that enters the assembly space 101c along with the lubricating oil, thereby helping the misted lubricating oil adhere to parts such as the first-type bearing 111, further improving the lubrication effect.

[0104] The following is an exemplary description of the working principle of a specific implementation scheme when the working medium output device 100 is a scroll compressor, the fluid working medium is a refrigerant, and the lubricating medium is lubricating oil, so that those skilled in the art can understand the concept of the present invention.

[0105] The mixture of lubricating oil and low temperature and low pressure refrigerant enters from the air inlet 101b on the casing 101 and Figure 1 The inner wall surface of the accommodating space 101a is cooled (in the orientation shown), and the mixture flows through the gap between the stator assembly 102 and the inner wall of the casing 101, as well as the air gap between the stator assembly 102 and the rotor assembly 103, to cool and lubricate the stator assembly 102, the rotor assembly 103, the third type bearing 113 and other components.

[0106] The mixture enters the boost chamber 109a through through-hole 109b. The remaining lubricant forms an oil film, lubricating and sealing the profile of the dynamic and static discs 110. After being compressed within the boost chamber 109a, the mixture is discharged from the inlet 110b into the primary oil separation chamber 110a. Some of the lubricant flows from the oil return hole 110c to the oil return chamber 110d, while the remaining lubricant flows with the refrigerant from the outlet 114a into the secondary oil separation chamber 114b. During this process, some of the lubricant in the secondary oil separation chamber 114b flows back into the primary oil separation chamber 110a through the oil guide port 114c. The mixture in the secondary oil separation chamber 114b then enters the cyclone separator. The cyclone separator separates a portion of the lubricant and returns it to the oil return chamber 110d due to gravity. The refrigerant and the remaining unseparated lubricant are then discharged from the compressor through the cyclone separator and continue circulating in the compressor's external piping, providing cooling or heating for the external environment.

[0107] When the lubricating oil flows back to the oil return chamber 110d, part of the refrigerant also flows into the oil return chamber 110d. The mixture of lubricating oil and refrigerant in the oil return chamber 110d is used to lubricate components such as the drive parts. Specifically, this mixture is reduced in pressure by the throttle valve 116 and flows from the oil return channel 110e to the assembly space 101c, lubricating the second type bearing 112 and the first type bearing 111. Figure 8 and Figure 9 During the flow process, part of the mixture flows into the boost chamber 109a formed by the dynamic and static disc profile lines through the back pressure hole 109c on the side of the dynamic disc 109 close to the crankshaft 105, which seals and lubricates the boost chamber 109a. The other part of the mixture is reduced in pressure by the threaded throttle valve 109d on the supporting surface of the casing 101 and flows into the accommodating space 101a, lubricating the third type bearing 113, the stator assembly 102, the rotor assembly 103 and other structures in the accommodating space 101a.
