[0002] This application claims priority to Chinese patent application No. 202510098973.1, filed on January 21, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of household appliance technology, and in particular to a gas-liquid separator, compressor unit and refrigeration equipment. Background Technology

[0004] In related technologies, compressor units are equipped with a gas-liquid separator, a liquid storage tank, and a compressor body arranged sequentially. The liquid storage tank separates the gas and liquid and stores the liquid. However, because the gas-liquid separation capacity of the liquid storage tank is insufficient, a separate gas-liquid separator is needed to compensate for this deficiency. This prevents the compressor body from experiencing liquid slugging when receiving gas from the liquid storage tank and the gas-liquid separator.

[0005] However, the gas-liquid separator and the liquid storage tank occupy a certain amount of internal space, and their connection requires multiple piping connections. Therefore, the compressor unit has many internal parts and a complex structure. Summary of the Invention

[0006] The main objective of this application is to provide a gas-liquid separator, a compressor unit, and a refrigeration device, with the aim of simplifying the structure of the compressor unit.

[0007] To achieve the above objectives, this application proposes a gas-liquid separator, which is used in a compressor body, the compressor body including a first cylinder and a second cylinder; the gas-liquid separator includes:

The first partition divides the internal space of the annular shell into a first cavity and a second cavity. Both the first cavity and the second cavity are provided with a second partition. The second partition is provided with a liquid passage hole. The second partition of the first cavity divides the first cavity into a gas-liquid separation chamber and an oil separation chamber. The second partition of the second cavity divides the second cavity into a gas-liquid separation chamber and an oil separation chamber.

[0013] In one embodiment, the first partition includes a first sub-partition and a second sub-partition, which are respectively arranged radially along the annular shell. The first sub-partition is connected to the inner annular shell wall and the outer annular sidewall, and the second sub-partition is connected to the inner annular shell wall and the outer annular sidewall, respectively. The first sub-partition and the second sub-partition divide the internal space of the annular shell into the first cavity and the second cavity.

[0014] In one embodiment, the first partition is arranged in a ring shape along the circumference and is spaced apart from both the inner ring shell wall and the outer ring sidewall. The first partition divides the internal space of the ring shell into the first cavity and the second cavity.

[0015] In one embodiment, the housing assembly is arranged in a ring shape, and the first partition is arranged in a ring shape circumferentially.

[0016] In one embodiment, the gas-liquid separator further includes a cover plate, which covers the top of the first gas separator and the second gas separator;

[0017] The cover plate is provided with mounting holes for mounting the air outlet assembly of the compressor.

[0018] In one embodiment, the first gas separator further includes a liquid drainage assembly for draining liquid from the first gas separator; and,

[0019] The second gas separator also includes a liquid drainage component for draining liquid from the second gas separator.

[0020] In one embodiment, the exhaust assembly of the first gas separator includes an exhaust pipe and an exhaust port, one end of the exhaust pipe is connected to the exhaust port, the exhaust pipe is arranged radially along the housing assembly, and the other end of the exhaust pipe is connected to the first cylinder.

[0021] The exhaust assembly of the second gas separator includes an exhaust pipe and an exhaust port. The inlet of the exhaust pipe is connected to the exhaust port. The exhaust pipe is arranged radially along the housing assembly, and the outlet of the exhaust pipe is connected to the second cylinder.

[0022] This application also provides a compressor device, the compressor device comprising:

[0023] The compressor body includes a first cylinder and a second cylinder; and

[0024] As described in any of the above gas-liquid separators, the housing assembly of the gas-liquid separator is arranged around the outer periphery of the compressor body; the first gas separator and the second gas separator have an intake assembly and an exhaust assembly, the exhaust assembly of the first gas separator is used to connect to the first cylinder, and the exhaust assembly of the second gas separator is used to connect to the second cylinder.

[0025] In one embodiment, the compressor body and the gas-liquid separator are spaced apart.

[0026] In one embodiment, the compressor device further includes an isolation layer disposed between the compressor body and the gas-liquid separator, the isolation layer comprising heat-absorbing material and / or sound-absorbing material.

[0028] In one embodiment, the gas-liquid separator is fitted into the compressor body.

[0029] In one embodiment, the gas-liquid separator is integrally formed with the casing of the compressor body.

[0030] In one embodiment, the compressor device further includes a base, on which the compressor body and the gas-liquid separator are disposed.

[0033] A gas-liquid separator as described in any of the above descriptions; or...

[0034] The compressor device as described in any of the above.

[0035] This application proposes a gas-liquid separator, including a housing assembly. A first gas separator and a second gas separator are formed within the housing assembly. Each of the first and second gas separators is equipped with an independent inlet assembly and an outlet assembly. The outlet assembly of the first gas separator is used to connect to a first cylinder of the compressor body, while the outlet assembly of the second gas separator is used to connect to a second cylinder of the compressor body. It is understood that the first and second gas separators replace the liquid receiver and gas-liquid separator in a conventional compressor unit, combining them into one. This reduces the number of internal components and lowers the system complexity. Furthermore, the housing assembly is arranged in a ring around the outer periphery of the compressor body. This not only effectively protects the compressor body from external environmental factors but also reduces compressor vibration and noise. It also reduces the risk of leakage and simplifies the installation process by eliminating the additional piping connection between the gas-liquid separator and the liquid receiver, which is typically required in conventional systems.

[0046] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Embodiments of the present invention

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0049] In related technologies, compressor units are equipped with a gas-liquid separator, a liquid receiver, and a compressor body arranged sequentially. The input end of the gas-liquid separator can be connected to an evaporator, the output end of the gas-liquid separator is connected to the input end of the liquid receiver, and the output end of the liquid receiver is connected to the input end of the compressor body (both input and output ends are for gas). It should be noted that while the liquid receiver is used to separate gas and liquid and store the liquid, its gas-liquid separation capacity is insufficient; therefore, a separate gas-liquid separator is needed to compensate for this deficiency. This prevents the compressor body from experiencing liquid slugging when receiving gas from the liquid receiver and the gas-liquid separator.

[0050] The aforementioned gas-liquid separator and storage tank present challenges due to their high space occupancy and complex structure. This can be explained by the fact that, since the gas-liquid separator and storage tank are independent units, their connection requires multiple piping lines. This not only increases the overall system volume but also complicates the internal layout. The piping not only occupies internal space but also requires precise positioning during installation, increasing assembly difficulty and time costs. Furthermore, the complex piping system and multi-component configuration increase the risk of leaks, necessitating more stringent quality control and maintenance checks, which indirectly contributes to the structural complexity.

[0051] To address the above problems, as shown in Figures 1, 4, and 5, this application proposes a gas-liquid separator 10 for a compressor body 400. The compressor body 400 includes a first cylinder 410 and a second cylinder 420. The gas-liquid separator 10 includes a housing assembly 100, which forms a first gas separator 210 and a second gas separator 220. The first gas separator 210 and the second gas separator 220 have an intake assembly 230 and an exhaust assembly 240. The exhaust assembly 240 of the first gas separator 210 is used to connect to the first cylinder 410, and the exhaust assembly 240 of the second gas separator 220 is used to connect to the second cylinder 420. The housing assembly 100 is arranged in a ring shape to surround the outer periphery of the compressor body 400.

[0052] In this embodiment, as shown in Figures 6 and 7, the compressor body 400 includes a first cylinder 410 and a second cylinder 420. The first cylinder 410 and the second cylinder 420 can operate in parallel or alternately to adapt to different cooling demands. Simultaneously, the dual-cylinder compressor body can flexibly adjust its operating mode according to the actual load. It can simultaneously activate both cylinders under high load to provide greater cooling capacity, or activate only one cylinder under low load to save energy and improve efficiency. Thus, the dual-cylinder compressor body 400 can balance the workload of the compressor body 400 and extend its service life.

[0053] In one embodiment, the first cylinder 410 and the second cylinder 420 can respectively perform high-pressure operation and low-pressure operation. The first cylinder 410 and the second cylinder 420 can be fixed to low-pressure and high-pressure operation respectively, or their roles can be flexibly switched according to the specific design of the compressor body 400 and the control strategy.

[0054] In one feasible embodiment, as shown in Figures 6 and 7, the compressor body 400 includes a pump body and a first cylinder 410 and a second cylinder 420 forming the pump body. The compressor body 400 has a first exhaust port 2411 and a second exhaust port 2412 connected to the pump body, which are respectively channels for the discharge of high-temperature, high-pressure gas compressed by the first cylinder 410 and the second cylinder 420. The first exhaust port 2411 is located at the top of the pump body, and the second exhaust port 2411 is located on the side of the pump body, ensuring that the compressed gas can smoothly enter the subsequent condenser or other system components. The compressor body 400 also includes an air inlet for the first cylinder 410 and an air inlet for the second cylinder 420, respectively located on one side of the first cylinder 410 and the second cylinder 420, for introducing low-temperature, low-pressure refrigerant gas from the evaporator or the gas-liquid separator 10.

[0055] Understandably, since liquid must not enter the air inlet of the compressor body 400, and the gas output from the evaporator inevitably contains residual liquid, if this residual liquid enters the compressor body 400, it will damage the compressor body 400, reducing its efficiency and service life. Therefore, a gas-liquid separator 10 is needed to separate the gas and liquid, preventing the compressor body 400 from suffering liquid slugging.

[0056] In this embodiment, as shown in Figures 1 to 3, the housing assembly 100 is a hollow housing assembly, and the housing assembly 100 forms a first gas separator 210 and a second gas separator 220, which can be formed in the hollow portion within the housing assembly 100. It is understood that the first gas separator 210 and the second gas separator 220 operate independently and can be physically separated by partitions or baffles to ensure that the gas flow within the first gas separator 210 and the second gas separator 220 does not interfere with each other. Further, both the first gas separator 210 and the second gas separator 220 include an intake assembly 230 and an exhaust assembly 240. The intake assembly 230 of the first gas separator 210 and the second gas separator 220 can be connected to an evaporator, and the exhaust assembly 240 of the first gas separator 210 and the second gas separator 220 can be connected to the compressor body 400. In one feasible implementation, the exhaust assembly 240 of the first gas separator 210 is connected to the first cylinder 410 via the air inlet of the first cylinder 410, and the exhaust assembly 240 of the second gas separator 220 is connected to the second cylinder 420 via the air inlet of the second cylinder 420. This ensures that the incoming refrigerant undergoes sufficient gas-liquid separation before being accurately delivered to the corresponding cylinder via the exhaust assembly 240, thus improving the system's stability and reliability.

[0057] It should be explained that the first gas fraction 210 and the second gas fraction 220 have the same structure. Figure 2 is a schematic diagram of the structure of the first gas fraction, and Figure 3 is a schematic diagram of the structure of the second gas fraction 220.

[0058] It should be explained that the first gas separator 210 and the second gas separator 220 are distinct from their respective connections to different cylinders of the compressor body 400, and may handle refrigerant gases at different pressure levels depending on the system design. In one embodiment, the exhaust assembly 240 of the first gas separator 210 is connected to the first cylinder 410 of the compressor body 400, while the exhaust assembly 240 of the second gas separator 220 is connected to the second cylinder 420. In some embodiments, the first gas separator 210 and the second gas separator 220 may be designated to handle refrigerant gases under low-pressure or high-pressure operating conditions, respectively. That is, one gas separator (e.g., the first gas separator 210) may be used to process low-temperature, low-pressure refrigerant gas from the evaporator, separating it and sending it to the first cylinder 410 for preliminary compression; while the other gas separator (e.g., the second gas separator 220) may receive the gas after preliminary compression or the gas directly from the evaporator, preparing to send it to the second cylinder 420 responsible for high-pressure compression. Thus, this design allows the dual-cylinder compressor body 400 to flexibly adjust its operating mode according to actual load conditions, improving the overall efficiency and responsiveness of the system.

[0059] It should be noted that both the first gas separator 210 and the second gas separator 220 include independent intake and exhaust assemblies 240. In one embodiment, the exhaust assembly 240 and intake assembly 230 of the first gas separator 210 and the second gas separator 220 may each include one or more interfaces and pipes, the specific number and layout depending on the design requirements and operating mode of the compressor body 400. For example, when higher separation efficiency or larger flow rate is required, multiple intake assemblies 230 can be provided in each gas separator to ensure sufficient gas inlets and improve the gas-liquid separation effect through multi-point intake. Similarly, multiple exhaust assemblies 240 can also be designed to better distribute the separated pure refrigerant gas to the corresponding cylinder, optimize the gas flow path, and reduce pressure loss. In addition, the configuration of multiple intake and exhaust assemblies 240 can enhance the flexibility of the system, allowing different intake and exhaust ports 241 to be used under different operating conditions (such as high load and low load) to achieve optimal operating performance. In one embodiment, as shown in FIG2, the exhaust assembly of the first gas separator 210 includes a first exhaust port 2411 and a first exhaust pipe 2421; as shown in FIG3, the exhaust assembly 240 of the second gas separator 220 includes a second exhaust port 2412 and a second exhaust pipe 2422.

[0060] It is understandable that the liquid receiver and gas-liquid separator in some exemplary compressor units have overlapping functions, both aiming to separate gas and liquid to ensure the efficient operation of the compressor body. Based on this, this application proposes to combine the liquid receiver and gas-liquid separator 10 in some exemplary compressor units 20 into one, forming the gas-liquid separator 10 proposed in this application. The gas-liquid separator 10 proposed in this application not only reduces the number of internal components and lowers system complexity but also significantly reduces internal space occupancy. By merging these two components, the piping and related component configurations originally connecting the liquid receiver and gas-liquid separator 10 in some exemplary compressor units 20 can be eliminated, further simplifying the overall structure of the compressor unit 20. This not only improves installation efficiency and reduces assembly time and cost but also reduces the leakage risk that may arise from the connection of multiple components, enhancing the stability and reliability of the system.

[0061] In this embodiment, as shown in Figures 1, 4, and 5, the housing assembly 100 is arranged in a ring shape to surround the outer periphery of the compressor body 400. That is, the housing assembly 100 is a hollow shell, forming a ring shape with a receiving cavity inside. Thus, the housing assembly 100 can cover the outer periphery of the compressor body 400, effectively protecting the internal compressor unit 20 from external environmental factors and optimizing space utilization, making the entire compressor unit 20 more compact and integrated. Furthermore, the housing assembly 100's ring-shaped arrangement around the compressor body 400, tightly integrated with it, reduces the additional piping connections required in traditional systems due to the separate installation of the gas-liquid separator 10 and the liquid storage tank, lowering the risk of leakage and simplifying the installation process.

[0062] Furthermore, it should be noted that the annular shell structure, surrounding the outer periphery of the compressor body 400, ensures that the noise emitted by the compressor body 400 during operation is isolated by the annular shell structure (shell assembly 100), thereby achieving better sound insulation. Moreover, this annular shell structure provides uniform heat exchange efficiency, helping to stabilize the operating temperature of the compressor body 400 and improve its operating efficiency.

[0063] In one embodiment, the housing assembly 100 can be a hollow annular column, i.e., a hollow cylindrical structure with two concentric cylindrical surfaces to form the housing assembly 100. This not only provides sufficient internal space to form the first gas separator 210 and the second gas separator 220, but also ensures the stability and strength of the structure. In other examples, the housing assembly 100 can also be a hollow elliptical annular column, a hollow rectangular annular column, a hollow square annular column, a hollow polygonal annular column, a hollow corrugated tube, or any other irregular shape. The specific shape is not limited here. The important thing is that the housing assembly 100 is a hollow housing assembly 100 for forming the first gas separator 210 and the second gas separator 220, and can be arranged around the outer periphery of the compressor body 400.

[0064] In this embodiment, the housing assembly 100 is made of a high-strength, lightweight material, possessing good mechanical properties, capable of withstanding pressure changes during operation, and exhibiting excellent corrosion resistance and sealing performance, which helps ensure the internal gas-liquid separation process. In one embodiment, the housing assembly 100 can be made of aluminum alloy, providing excellent mechanical properties and corrosion resistance while maintaining low weight; stainless steel, such as 304 or 316L, can also be used to ensure excellent corrosion resistance and long service life in harsh environments; in addition, composite materials, such as glass fiber reinforced plastic or carbon fiber reinforced plastic, can also be used, as these materials are not only lightweight and high-strength, but also have excellent corrosion resistance and thermal insulation properties.

[0065] In summary, this application proposes a gas-liquid separator 10, including a housing assembly 100. The housing assembly 100 internally forms a first gas separator 210 and a second gas separator 220. Each of the first and second gas separators 210 is equipped with an independent intake assembly 230 and an exhaust assembly 240. The exhaust assembly 240 of the first gas separator 210 is used to connect to the first cylinder 410 of the compressor body 400, while the exhaust assembly 240 of the second gas separator 220 is used to connect to the second cylinder 420 of the compressor body 400. It is understood that the first and second gas separators 210 and 220 replace the liquid storage tank and gas-liquid separator 10 in a conventional compressor device 20, combining the two into one. This reduces the number of internal components and lowers the system complexity. Furthermore, the housing assembly 100 is arranged in a ring around the outer periphery of the compressor body 400. This not only effectively protects the compressor body 400 from external environmental factors, but also reduces the vibration and noise of the compressor body 400, enhances the heat insulation effect of the compressor unit 20, reduces the risk of leakage by reducing the additional pipeline connection between the gas-liquid separator 10 and the liquid storage tank in the traditional system, and simplifies the installation process.

[0066] In one embodiment, as shown in FIG1, the housing assembly 100 includes an annular housing, a first partition 110, and a second partition. The annular housing has an inner annular shell wall 120 and an outer annular sidewall 130 disposed opposite to each other. The first partition 110 is disposed between the inner annular shell wall and the outer annular sidewall, dividing the internal space of the annular housing into a first cavity and a second cavity. Both the first and second cavities are provided with a second partition, which has a liquid passage hole. The second partition of the first cavity divides the first cavity into a gas-liquid separation cavity and an oil separation cavity, and the second partition of the second cavity divides the second cavity into a gas-liquid separation cavity and an oil separation cavity.

[0067] It is understood that in this embodiment, the annular housing has an inner annular shell wall 120 and an outer annular sidewall 130 disposed opposite to each other, forming a hollow annular structure surrounding the outer periphery of the compressor body 400. A first partition 110 is provided inside the annular housing, located between the inner annular shell wall 120 and the outer annular sidewall 130, dividing the internal space of the annular housing into a first cavity and a second cavity. The first cavity and the second cavity are used to form a first gas separator 210 and a second gas separator 220. The first partition 110 is arranged radially along the housing assembly 100, extending from the top end of the housing assembly 100 to the bottom end, to form two enclosed spaces, namely the first cavity and the second cavity.

[0068] It is important to note that each cavity is equipped with a second baffle with a liquid passage hole, extending from the inner ring shell wall 120 of the housing assembly 100 to the outer ring side wall 130. The liquid passage hole allows liquid to pass through but restricts gas flow, ensuring effective gas-liquid separation. The second baffles in the first and second cavities respectively divide their respective spaces into two functional areas: a gas-liquid separation chamber and an oil separation chamber. The gas-liquid separation chamber receives the refrigerant mixture from the evaporator, achieving gas-liquid separation and ensuring that only pure gaseous refrigerant can enter the corresponding cylinder of the compressor body 400 through the exhaust assembly 240. The oil separation chamber is responsible for separating lubricating oil from the refrigerant gas, preventing lubricating oil from entering the compressor body 400 and causing damage or efficiency reduction. This not only improves the gas-liquid separation effect but also simultaneously achieves oil separation, reducing wear on internal components of the compressor body 400 and extending the service life of the equipment.

[0069] In one embodiment, the material of the first partition 110 can be the same as that of the housing assembly 100. The first partition 110 can be an aluminum alloy, which provides excellent mechanical properties and corrosion resistance while maintaining a low weight; stainless steel can also be used to ensure excellent corrosion resistance and long service life in harsh environments; in addition, composite materials such as glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP) can also be used, which are not only lightweight and high-strength, but also have excellent corrosion resistance and thermal insulation properties.

[0070] There are two possible implementation methods for the first partition 110, as detailed below.

[0071] In one embodiment, as shown in Figures 1 to 3, the first partition 110 includes a first sub-partition 111 and a second sub-partition 112. The first sub-partition 111 and the second sub-partition 112 are respectively arranged radially along the annular shell. The first sub-partition 111 is connected to the inner annular shell wall 120 and the outer annular side wall 130, respectively. The second sub-partition 112 is also connected to the inner annular shell wall 120 and the outer annular side wall 130, respectively. The first sub-partition 111 and the second sub-partition 112 divide the internal space of the annular shell into the first cavity and the second cavity. It should be explained that the first gas separator 210 and the second gas separator 220 have the same structure. Figure 2 is a schematic diagram of the structure of the first gas separator, and Figure 3 is a schematic diagram of the structure of the second gas separator 220. Figures 2 and 3 are schematic diagrams of the first gas separator 210 and the second gas separator 220 formed after separation by the first sub-partition 111 and the second sub-partition 112 in the gas-liquid separator 10.

[0072] In this embodiment, both the first sub-partition 111 and the second sub-partition 112 are arranged radially along the annular shell and are connected to the inner annular shell wall 120 and the outer annular sidewall 130, respectively. This clearly divides the internal space of the annular shell into a first cavity on the left and a second cavity on the right, ensuring that the airflow between the two cavities does not interfere with each other and providing a good separation effect. Furthermore, since the sub-partitions are directly connected to the inner and outer walls of the annular shell, the structural strength of the entire device is enhanced, helping to withstand pressure changes generated during operation. This design is likely more convenient for production and assembly, and also facilitates later inspection and maintenance.

[0073] In one embodiment (not shown in the figure), the first partition 110 is arranged in a ring shape along the circumference and is spaced apart from the inner ring shell wall 120 and the outer ring side wall 130. The first partition 110 divides the internal space of the annular shell into the first cavity and the second cavity.

[0074] In this embodiment, the first partition 110 is arranged circumferentially, maintaining a certain distance from both the inner annular shell wall 120 and the outer annular sidewall 130, thus forming an annular partition. The first partition 110 divides the internal space of the annular shell into two parts: an inner first cavity and an outer second cavity. The size of the first and second cavities depends on the distance between the first partition 110 and the inner annular shell wall 120 and the outer annular sidewall 130. Thus, the first partition 110 not only creates an additional flow area inside the annular shell, helping to improve heat exchange efficiency, but also reduces the transmission of vibrations generated during the operation of the compressor body 400 to the gas-liquid separator 10, thereby reducing noise levels. In one embodiment, the shell assembly 100 is annularly arranged, and the first partition 110 is also annularly arranged circumferentially. This allows for better space division by matching the shapes of the shell assembly 100 and the first partition 110. In another embodiment, the shape of the first partition 110 is adapted to the shape of the shell assembly 100. It should be noted that the shape of the first partition 110 is not limited here. What is important is that the first partition 110 is positioned to separate the inner ring shell wall 120 and the outer ring side wall 130.

[0075] It is understandable that in the two embodiments of the first partition 110 described above, the two different arrangements of the first partition 110 each have their own characteristics and are suitable for different operating conditions. The first arrangement is suitable for applications that require strict differentiation between the left and right cavities, especially when there are significant differences in the working conditions or processing media on both sides. The second arrangement is more suitable for situations that require better heat exchange performance, such as in noise-sensitive environments or environments that require optimized heat management. The choice of which design scheme to use should be based on specific application requirements, operating conditions, and expected performance indicators. Importantly, whether radial segmentation or annular spacing is used, the goal is to form the first and second cavities.

[0076] In one embodiment, the housing assembly 100 is arranged in a ring shape. Firstly, the ring-shaped structure ensures a uniform distribution of internal space, allowing the gas-liquid separation chamber and oil separation chamber to be evenly distributed within the ring-shaped housing. This helps maintain stable fluid flow characteristics and avoids the problem of low separation efficiency that may result from uneven load in localized areas. Secondly, the ring-shaped housing assembly 100 promotes uniform heat exchange. The ring-shaped design surrounding the compressor body 400 creates a continuous and uniform heat exchange interface, allowing heat to be transferred evenly throughout the entire ring area. This not only improves heat exchange efficiency but also prevents potential localized overheating, thereby helping to maintain the stability of the compressor body 400's operating temperature and extending the equipment's service life.

[0077] Therefore, the advantage of the annular housing assembly 100 over other shapes (such as elliptical, rectangular, square, polygonal, or corrugated tubular shapes) is that it can provide the most uniform space utilization and heat exchange efficiency. Due to the symmetry and continuity of the annular structure, a uniform interface without obvious corners or edges can be created around the outer periphery of the compressor body 400, ensuring a more consistent distribution of the internal gas-liquid separation chamber and oil separation chamber, and avoiding local differences in fluid flow and heat transfer caused by irregular geometry.

[0078] In one embodiment, as shown in FIG1, the gas-liquid separator 10 further includes a cover plate 300, which covers the top of the housing assembly 100. The cover plate 300 has mounting holes 310 for mounting the compressor's outlet assembly 430. It is understood that the cover plate 300 is installed at the top of the first gas separator 210 and the second gas separator 220, serving to seal and protect the internal components. The mounting holes 310 on the cover plate 300 correspond to the position of the compressor body 400's exhaust assembly 240, allowing the exhaust assembly 240 to directly pass through the cover plate 300 and connect to other devices to discharge compressed gas. This simplifies the assembly process, ensures accurate connection between components, and by integrating the exhaust assembly 240 onto the cover plate 300, optimizes the airflow path, reduces pressure loss, and improves gas-liquid separation efficiency.

[0079] On the other hand, the cover plate 300 is located at the top of the gas-liquid separator 10 to ensure that the compressor body 400 is in a relatively enclosed space, which can achieve a certain sound insulation effect.

[0080] In this embodiment, the material of the cover plate 300 is not limited, but it needs to play a certain protective role. It can also be a material with strong sound insulation ability to enhance the sound insulation effect.

[0081] In one embodiment, the first gas separator 210 further includes a liquid draining assembly for draining liquid from within the first gas separator 210; and the second gas separator 220 further includes a liquid draining assembly for draining liquid from within the second gas separator 220. It is understood that the liquid draining assembly is used to drain liquid accumulated within each gas separator. By providing the liquid draining assembly, excess liquid generated during the gas-liquid separation process can be effectively and promptly discharged, ensuring that only pure gaseous refrigerant is delivered to the corresponding cylinder of the compressor body 400, avoiding liquid slugging and protecting the compressor body 400 from damage. Thus, the liquid draining assembly not only improves the stability and safety of the system but also optimizes the gas-liquid separation effect, ensuring high-efficiency refrigeration performance.

[0082] In one embodiment, as shown in Figures 2 and 3, the exhaust assembly 240 of the first gas separator 210 includes an exhaust pipe 242 and an exhaust port 241. One end of the exhaust pipe 242 is connected to the exhaust port 241, the exhaust pipe 242 is arranged radially along the housing assembly 100, and the other end of the exhaust pipe 242 is connected to the first cylinder 410. Similarly, the exhaust assembly 240 of the second gas separator 220 includes an exhaust pipe 242 and an exhaust port 241. The inlet of the exhaust pipe 242 is connected to the exhaust port 241, the exhaust pipe 242 is arranged radially along the housing assembly 100, and the outlet of the exhaust pipe 242 is connected to the second cylinder 420. It is understood that the exhaust assemblies 240 of the first and second gas separators 210 are used to deliver the purified gaseous refrigerant, after gas-liquid separation, to the cylinders of the corresponding compressor bodies 400. In the exhaust assembly 240 of the first gas separator 210, one end of the exhaust pipe 242 is connected to the exhaust port 241. The exhaust pipe 242 is arranged radially along the housing assembly 100, and its other end is directly connected to the first cylinder 410, ensuring that the gas discharged from the first gas separator 210 can smoothly enter the first cylinder 410 for compression. Similarly, the exhaust assembly 240 of the second gas separator 220 also includes an exhaust pipe 242. The inlet of the exhaust pipe 242 is connected to the exhaust port 241. The exhaust pipe 242 is also arranged radially along the housing assembly 100, and its outlet is connected to the second cylinder 420, so that the gas in the second gas separator 220 can be directly sent into the second cylinder 420.

[0083] It should be explained that the length and material selection of the exhaust pipe 242 directly affect the system's vibration control and overall service life. If the exhaust pipe 242 is too short and made of rigid material, it may become a major source of vibration because a short, rigid pipe cannot effectively absorb the vibrations generated during compressor operation, which may then be transmitted to the gas-liquid separator 10 and other connecting components, leading to increased noise, loose connections, and even accelerated component aging and damage. Therefore, in order to reduce vibration and extend the system's service life, in this embodiment, although the exhaust pipe 242 needs to maintain a rigid pipe structure to ensure the reliability and sealing of gas transmission, vibration reduction can be achieved by appropriately lengthening the exhaust pipe 242. A longer exhaust pipe 242 can be bent to a certain extent or form a slight arc, which helps to absorb and disperse the vibration energy from the compressor, reducing the amount of vibration directly transmitted to the gas-liquid separator 10 and other components. In another embodiment, flexible supports or flexible connectors (such as rubber joints) can also be used to install the exhaust pipe 242 to ensure that additional vibration reduction is provided without sacrificing the characteristics of rigid pipes.

[0084] In one embodiment, the exhaust pipe 242 may be made of copper.

[0085] In one embodiment, the exhaust pipe 242 of the first air separator 210 and the exhaust pipe 242 of the second air separator 220 are spaced apart and do not contact each other, thereby reducing mutual influence and effectively enhancing shock absorption capacity.

[0086] This application also provides a compressor device 20, as shown in Figures 4 and 5. The compressor device 20 includes a compressor body 400 and a gas-liquid separator 10. It should be noted that the compressor device 20 includes a gas-liquid separator 10, and the specific structure of the gas-liquid separator 10 refers to the above embodiments. Since the compressor device 20 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0087] Figures 4 and 5 show the structural schematic diagrams of the compressor device 20, and Figures 6 and 7 show the structural schematic diagrams of the compressor body 400.

[0088] In one embodiment, as shown in FIG5 or FIG7, the compressor body 400 has a first cylinder 410 and a second cylinder 420; the housing assembly 100 of the gas-liquid separator 10 is disposed around the outer periphery of the compressor body 400; the first gas separator 210 and the second gas separator 220 have an intake assembly 230 and an exhaust assembly 240, wherein the exhaust assembly 240 of the first gas separator 210 is used to connect to the first cylinder 410, and the exhaust assembly 240 of the second gas separator 220 is used to connect to the second cylinder 420. It is understood that this layout optimizes space utilization, reduces the risk of leakage by minimizing additional piping connections, and simplifies the installation process.

[0089] Furthermore, this compressor unit 20 can be widely used in applications requiring efficient gas-liquid and oil separation, such as refrigeration systems, air conditioning systems, and heat pump systems. Since the compressor unit 20 includes the gas-liquid separator 10 designed above, its internal structure is simplified. Therefore, when the compressor unit 20 is applied to refrigeration systems, air conditioning systems, and heat pump systems, the internal structures of those systems are also simplified.

[0090] It is understood that the compressor body 400 and the gas-liquid separator 10 can have various layout arrangements. The first is that they are spaced apart, the second is that they are attached to each other, and the third is that they are integrated. Further explanation can be found in the following embodiments.

[0091] In one embodiment, as shown in FIG5, the compressor body 400 and the gas-liquid separator 10 are spaced apart. This allows the compressor body 400 and the gas-liquid separator 10 to operate independently under their respective optimal conditions, reducing mutual interference and ensuring higher operating efficiency and stability. Furthermore, the spaced arrangement effectively controls the transmission of vibrations caused by compressor operation, reducing noise generation and improving the user experience.

[0092] When the compressor body 400 and the gas-liquid separator 10 are spaced apart, the distance between them can be greater than a preset safety distance. Due to vibration transmission, heat effects, and installation and maintenance requirements, this preset safety distance is necessary to ensure they do not interfere with each other. For example, vibration transmission can affect the other's performance through air or rigid connections. This effectively avoids mechanical stress damage and increased noise caused by vibration, while also preventing heat conduction from affecting sensitive components. The value of the preset safety distance can be adjusted according to the specific requirements of the actual application scenario (such as compressor power, ambient temperature, space constraints, etc.) to ensure optimal operating conditions and safety.

[0093] In this embodiment, to further enhance the sound insulation effect of the compressor unit 20, the compressor unit 20 also includes an isolation layer 500, which is disposed between the compressor body 400 and the gas-liquid separator 10. It can be understood that the isolation layer 500 can be considered as a physical barrier to block the noise propagation path, thereby significantly reducing the noise level generated by the compressor operation. The material of the isolation layer 500 can be a sound-absorbing material, such as sound-absorbing felt, rubber, or special composite materials, which can effectively absorb and reflect sound waves, reducing noise transmission. Furthermore, the presence of the isolation layer 500 not only helps improve the ambient noise level but also provides additional protection for the compressor body 400 and the gas-liquid separator 10, preventing the transmission of mechanical stress and vibration that may be caused by direct contact between the two. Thus, the introduction of the isolation layer 500 improves the overall quietness of the compressor unit 20 and also protects the compressor unit 20.

[0094] In one embodiment, the isolation layer 500 is respectively fitted to the gas-liquid separator 10 and the compressor body 400 on both sides. It is understood that this fitted design ensures that the isolation layer 500 can maximize its sound insulation performance, leaving no gaps that could lead to noise leakage. The fitted arrangement also enhances the overall stability of the structure, preventing the isolation layer 500 from shifting or failing due to external vibration or internal pressure changes. Through precise dimensional matching and appropriate fixing methods (such as adhesives or mechanical fasteners), a seamless connection can be achieved between the isolation layer 500 and the compressor body 400 and the gas-liquid separator 10, thereby providing a continuous and effective sound barrier. Thus, the fitted isolation layer 500 brings better sound insulation to the compressor unit 20.

[0095] In one embodiment, the isolation layer 500 may include not only sound-insulating materials but also integrated heat-absorbing materials to simultaneously address noise and heat management issues. This multifunctional isolation layer 500 effectively blocks the propagation of noise generated during compressor operation and absorbs and disperses heat dissipated by the compressor, preventing direct heat transfer to the gas-liquid separator 10 and its impact on efficiency and stability. The heat-absorbing materials are typically chosen based on their high heat capacity and good thermal conductivity, such as phase change materials (PCMs), ceramic fibers, or metal foams. By combining sound insulation and heat absorption properties, the isolation layer 500 significantly improves the sound insulation of the compressor unit 20 and optimizes thermal management performance, ensuring that both the compressor and the gas-liquid separator 10 operate under optimal temperature conditions, thereby extending equipment life, improving overall system efficiency, and reducing maintenance requirements.

[0096] In some exemplary compressor units, the gas-liquid separator and the liquid receiver are located in different positions. Specifically, the liquid receiver is located within the compressor body, while the gas-liquid separator is located at a distance from the compressor body. It should be noted that since the compressor body vibrates during operation, an acoustic enclosure is installed around the compressor body to reduce noise impact on the user. This acoustic enclosure surrounds the compressor body and the liquid receiver. However, the acoustic enclosure has limited mass and only serves as sound insulation, offering no vibration damping effect, and its low-to-mid-frequency sound insulation is limited. Therefore, the structure of the gas-liquid separator 10 and the design of the isolation layer 500 in the compressor unit 20 proposed in this application not only improves the overall sound insulation of the compressor unit 20 but also optimizes thermal management and vibration control, overcoming the shortcomings of traditional acoustic enclosures.

[0097] In one embodiment (not shown in the figures), the gas-liquid separator 10 is fitted snugly to the compressor body 400. It is understood that by tightly mounting the gas-liquid separator 10 onto the outer surface of the compressor body 400 with virtually no gap between them, a compact, integrated structure is formed. The main advantage of this snug fit is that it significantly reduces the overall volume of the system, making the entire compressor unit 20 more compact and saving installation space. Furthermore, the snug fit simplifies piping connections, reduces the need for additional piping, lowers the risk of leakage, and improves the system's sealing and reliability.

[0098] In one embodiment (not shown in the figures), the gas-liquid separator 10 is integrally formed with the housing of the compressor body 400. It is understood that the integrated design integrates the function of the gas-liquid separator 10 into the housing of the compressor body 400, achieving a seamless connection through processes such as molding or welding. This integrated design not only further optimizes space utilization, making the entire device more compact, but also enhances the overall integrity and stability of the structure, reducing potential failure points caused by aging or loosening of connecting parts. More importantly, the integrated design ensures efficient heat exchange between the gas-liquid separator 10 and the compressor body 400, helping to maintain the compressor's optimal operating temperature and improve refrigeration efficiency.

[0099] It should be explained that, in one example, when the gas-liquid separator 10 is integrally formed with the compressor body 400, the inner annular shell wall 120 of the gas-liquid separator 10 serves as the housing of the compressor body 400. This design not only simplifies the structure but also enhances the compactness and robustness of the overall device. Specifically, by directly using the inner annular shell wall 120 of the gas-liquid separator 10 as the housing of the compressor body 400, additional connections and interfaces between the two are eliminated, reducing potential leakage points and sources of failure.

[0100] It should be noted that when the gas-liquid separator 10 is fitted to the compressor body 400 and the two are integrally formed, in the application scenario where the first partition 110 of the gas-liquid separator 10 distinguishes the left and right chambers, the exhaust ports 241 of the exhaust assemblies 240 of the two chambers can be directly connected to the air inlet of the cylinder of the compressor body 400 through valves, thereby reducing more components (such as piping) and making it easier to simplify the design. In the application scenario where the first partition 110 of the gas-liquid separator 10 forms a ring-shaped partition, in the two chambers, the exhaust port 241 of the exhaust assembly 240 of the chamber closer to the compressor can be directly connected to the air inlet of the cylinder of the compressor body 400 through valves, thereby reducing more components (such as piping) and making it easier to simplify the design.

[0101] In one embodiment, as shown in Figures 4 and 5, the compressor unit 20 further includes a base 600, on which the compressor body 400 and the gas-liquid separator 10 are disposed. It is understood that the base 600 provides a stable foundation support for the entire compressor unit 20, ensuring its stability during operation and preventing it from being affected by external vibrations or impacts. The base 600 is typically made of high-strength materials, such as cast iron or thick steel plates, to withstand the weight and vibration loads generated during compressor operation. Furthermore, the base 600 may integrate fixing holes or other fixing structures to facilitate the secure installation of the entire unit in a predetermined location, such as the ground, equipment platform, or other infrastructure. By placing the compressor body 400 and the gas-liquid separator 10 together on the same base 600, not only is the installation process simplified, but the relative positions of the two remain fixed, reducing errors caused by movement or adjustment and improving the overall consistency and reliability of the system.

[0102] In this embodiment, as shown in Figures 4 and 5, the base 600 includes a plurality of first mounting screw holes, and the casing of the compressor body 400 also has a connector. The connector has second mounting screw holes 440 that are adapted to the plurality of first mounting screw holes. Thus, the compressor body 400 can be fixedly installed to the base 600 through the first mounting screw holes and the second mounting screw holes 440. The gas-liquid separator 10 is covered in the corresponding position, or it can be fixedly installed to the base 600 through the mounting screw holes.

[0103] In one embodiment, the compressor unit 20 further includes a pad 700 disposed between the base 600 and the gas-liquid separator 10. It is understood that the pad 700 can optimize the vibration damping performance and thermal management of the compressor unit 20. The pad 700 can be made of materials with high elasticity and good shock absorption, such as rubber, polyurethane foam, or spring steel sheets. These materials can effectively absorb and disperse vibration energy from the compressor body 400, preventing it from being directly transmitted to the gas-liquid separator 10, thereby reducing noise generation and protecting sensitive components from mechanical stress damage. Furthermore, the pad 700 also serves as thermal insulation, preventing heat generated by the compressor body 400 from being directly conducted to the gas-liquid separator 10, thus affecting its operating efficiency.

[0104] By selecting the material and thickness of the pad 700, the vibration reduction and heat insulation effects can be flexibly adjusted according to the needs of specific application scenarios, ensuring that the compressor unit 20 can maintain optimal performance under various working conditions.

[0105] This application also provides a refrigeration device, which includes a gas-liquid separator 10 or a compressor unit 20. It should be noted that the specific structure of the gas-liquid separator 10 or the compressor unit 20 is as described in the above embodiments. Since this refrigeration device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments.

[0106] In one embodiment, the refrigeration equipment may include air conditioners, refrigerators, freezers, heat pump systems, and other equipment widely used in residential, commercial, and industrial settings. When the refrigeration equipment includes an air conditioner, the air conditioner may be one of a cabinet air conditioner, a central air conditioner, a split-type air conditioner, or a window air conditioner.

[0107] When the refrigeration equipment is an air conditioner, the compressor unit 20 can be installed in the outdoor unit of the air conditioner. Since the compressor unit 20 has a simple internal structure, few components, and can achieve more effective vibration reduction and noise reduction, when the refrigeration equipment uses the compressor unit 20, it also has more effective vibration reduction and noise reduction.

[0108] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
