[0002] In fluid handling equipment, the gas-liquid separation partition of the liquid separator plays a vital role, and its performance directly affects the working efficiency and stability of the equipment.

[0003] Currently, in liquid accumulators and related compressor technologies used in compressors, the accumulator's partition assembly typically consists of a cylinder connected to the inner circumference of the main body and a partition positioned within the cylinder. While this structure effectively improves the accumulator's rigidity, raises its natural frequency, and reduces vibration and noise, it is ineffective at achieving high-efficiency gas-liquid separation and cannot meet the requirements for efficient gas-liquid separation.

[0004] In addition, some existing partitions, liquid distributors and compressor products use a partition structure that includes a driving part and an opening conversion part. This design makes the overall structure implementation process complicated, which not only increases the difficulty of assembly, but also greatly increases the production cost, which is not conducive to the large-scale promotion and application of the product.

[0005] Another example is the liquid separator used in air-conditioning compressors. A spherical baffle, integrally connected to the baffle body, covers the gas-liquid separation hole. This baffle blocks the liquid in the gas-liquid mixture to achieve gas-liquid separation. However, the processing of this spherical baffle requires stringent material properties and is complex and difficult, further driving up product costs and limiting its market competitiveness.

[0047] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0048] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0049] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures. These relative terms include, for example, "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "rear," and the like. Such spatially relative terms are intended to encompass different orientations of the device during use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, changes position, or changes motion, these directional indications will change accordingly. For example, an element described as "below" or "beneath" another element or feature would subsequently be oriented "above" or "above" the other element or feature. Thus, the example term "below" can encompass both above and below orientations. The device may be oriented differently (rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0050] During the operation of the compressor, there will be a certain amount of liquid refrigerant in the liquid distributor. When the gaseous refrigerant enters the compressor, some liquid refrigerant will be brought in. In order to ensure the energy efficiency of the compressor, the amount of liquid carried in the exhaust of the liquid distributor should be minimized.

[0051] However, the existing liquid separator still carries a large amount of liquid in the exhaust. In order to alleviate this problem, the gas-liquid separation partition provided in the embodiment of the present application increases the gas-liquid separation path, which can further separate the gas and liquid, reduce the liquid refrigerant entering the straight pipe, reduce the liquid amount carried in the exhaust of the liquid separator, improve the gas-liquid separation rate and the stiffness of the liquid separator, reduce noise and vibration, and improve and higher ensure the energy efficiency of the compressor.

[0052] Specifically, refer to Figures 1-9, the embodiment of the present application provides a gas-liquid separation partition, which is applied to a liquid separator, comprising: a first partition 1, a second partition 2 located below the first partition 1, and a cylinder 3 connected between the first partition 1 and the second partition 2, wherein the first partition 1, the cylinder 3 and the second partition 2 form an integrated structure; a one-way channel for fluid circulation is reserved between the outer walls of the first partition 1, the second partition 2 and the cylinder 3; the first partition 1 has a first flow hole 11, and the first flow hole 11 is configured to communicate with the one-way channel or the inner cavity of the cylinder 3 so that the The gas-liquid mixed fluid in the space above the first partition 1 flows to the one-way channel or the inner cavity of the cylinder 3; the cylinder 3 has a third flow hole 31, and the third flow hole 31 is configured to connect the one-way channel with the inner cavity of the cylinder 3 so that the gas-liquid mixed fluid or the gaseous fluid can flow between the two; the second partition 2 has a second flow hole 21, and the second flow hole 21 is configured to connect with the one-way channel or the inner cavity of the cylinder 3 so that the liquid fluid deposited in the space above the second partition 2 can flow out, or the gaseous fluid in the space above the second partition 2 can flow out.

[0053] For example, the integrated structure formed by the first partition 1, the cylinder 3 and the second partition 2 can be an integrated synthetic structure formed by injection molding or other processing technology, without the need for other structural parts to connect; forming an overall three-dimensional support frame, it has stronger anti-deformation ability than the split structure.

[0054] For example, the integrated structure formed by the first partition 1, the cylinder 3 and the second partition 2 may also be an integrated structure formed by a combination of connectors, which is easier to disassemble or maintain.

[0055] Among them, the gas-liquid separation partition has a simple structure. Under the structural setting of the integrated gas-liquid separation partition, through the setting of the first flow hole 11, the second flow hole 21 and the third flow hole 31, the gas-liquid mixed fluid flowing in from the top of the first partition 1 can form multiple gas-liquid separation paths between the first partition 1, the one-way channel, the cylinder 3 and the second partition 2 during the process of flowing through the gas-liquid separation partition, thereby achieving an efficient gas-liquid separation effect.

[0056] The gas-liquid separation partition provided in the embodiment of the present application achieves a comprehensive improvement in gas-liquid separation performance and comprehensive product performance by designing the gas-liquid separation partition as an integrated structure and scientifically arranging the first flow hole 11, the second flow hole 21 and the third flow hole 31: the integrated structure avoids the assembly gap and stress concentration problems caused by the connecting parts of the traditional split partition, improves the partition stiffness, effectively suppresses the vibration and noise caused by the impact of the airflow, and reduces the operating noise.

[0057] Considering the first gas-liquid separation path scheme, in the gas-liquid separation partition scheme provided in the embodiment of the present application, the first flow hole 11 is used to connect the upper space of the first partition 1 with the one-way channel; the second flow hole 21 is used to connect the one-way channel with the lower space of the second partition 2; the third flow hole 31 is used to connect the one-way channel with the inner cavity of the cylinder 3; the gas-liquid mixed fluid is configured to flow to the one-way channel through the first flow hole 11, liquid deposition is performed in the one-way channel, the liquid fluid flows out through the second flow hole 21, and the gaseous fluid flows to the inner cavity of the cylinder 3 through the third flow hole 31, and flows out from the inner cavity of the cylinder 3.

[0058] In this way, after the gas-liquid mixed fluid enters through the first flow hole 11, the flow rate drops sharply due to the expansion of the channel cross-sectional area, and the liquid refrigerant quickly settles to the bottom of the channel due to gravity to form a stable liquid layer; the residual droplets are further captured due to inertial impact on the channel wall, thereby improving the initial separation efficiency; the second flow hole 21 directionally drains the liquid refrigerant at the bottom of the channel to avoid the liquid layer from being mixed with the air flow disturbance, ensuring that the liquid "only goes out but not in"; the third flow hole 31 only allows gaseous fluid (and extremely fine droplets) to enter the inner cavity of the cylinder 3, and through "forced diversion of gas and liquid", the liquid volume entering the subsequent flow channel is compressed, laying the foundation for the low liquid volume of the final exhaust.

[0059] Considering the position scheme of the first flow hole 11 in the first gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the first flow hole 11 is located near the peripheral area of ​​the first partition 1, and the first flow hole 11 is located outside the cylinder 3.

[0060] In this way, by utilizing the long-path sedimentation effect, when the gas-liquid mixed fluid cuts into the one-way channel from the peripheral area of ​​the first partition 1, the liquid refrigerant is more likely to settle to the bottom of the channel due to inertial lag and gravity traction, thereby improving the capture rate of the initial separation droplets and reducing the amount of liquid in the subsequent flow channel from the source; it can suppress turbulence, reduce flow pressure drop, reduce system energy consumption, and improve the suction efficiency of the compressor; the load of the first partition 1 is dispersed, and the annular support frame is cooperated to improve the structural deformation resistance and service life; the "peripheral liquid path + central gas path" space partition is realized to prevent secondary mixing of gas and liquid, reduce the amount of liquid carried by the exhaust of the separator, and increase the gas-liquid separation rate; the large-capacity sedimentation space of the peripheral channel enhances the adaptability to variable working conditions such as high liquid content, reduces the fluctuation of separation efficiency under variable working conditions, and ensures the stable operation of the compressor under all working conditions. Through the triple optimization of flow path, structure, and function, it breaks through the bottleneck of traditional liquid separators and provides a high-efficiency, low-resistance, and long-life solution.

[0061] Considering the position scheme of the second flow hole 21 in the first gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the second flow hole 21 is located near the peripheral area of ​​the second partition 2, and the second flow hole 21 is located outside the cylinder 3.

[0062] In this way, the liquid refrigerant deposited in the one-way channel can be discharged more smoothly from the peripheral position near the bottom of the channel due to the peripheral layout of the second flow hole 21, with the help of gravity and fluid flow inertia, thereby reducing the retention and accumulation of liquid refrigerant in the one-way channel, avoiding secondary entrainment caused by excessive liquid accumulation, and improving the thoroughness of drainage of a single separation; in addition, this position echoes the peripheral layout of the first flow hole 11, making the flow path of gas and liquid in the one-way channel more regular, promoting gas-liquid stratification, and utilizing the relatively stable flow field environment in the peripheral area to reduce airflow interference during drainage, thereby ensuring the continuity and stability of gas-liquid separation; it can effectively drain liquid, ensure that the liquid separator maintains an efficient separation state, reduce the introduction of liquid refrigerant at the suction end of the compressor, and improve the operating efficiency of the compressor. At the same time, the vibration and noise problems caused by liquid accumulation are also alleviated, enhancing the adaptability and reliability of the liquid separator and the compressor system, and achieving coordinated optimization of gas-liquid separation efficiency, system stability and energy efficiency through the precise arrangement of drainage channels on the periphery.

[0063] Considering the position scheme of the third through-flow hole 31 in the first gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the third through-flow hole 31 is located in the lower area of ​​the side wall of the cylinder 3.

[0064] In this way, setting the third flow hole 31 in the lower area of ​​the side wall of the cylinder 3 can make full use of the characteristic that the liquid refrigerant in the gas-liquid mixed fluid is easy to deposit at the bottom due to its high density, so that the gaseous fluid after gas-liquid separation in the one-way channel can enter the inner cavity of the cylinder 3 from the one-way channel more efficiently when flowing through this position, thereby reducing the entrainment of residual liquid refrigerant in the gaseous fluid; at the same time, the layout of the lower area conforms to the gas-liquid stratification law under the action of gravity. When the gaseous fluid flows upward through the third flow hole 31, the liquid refrigerant is more likely to remain at the bottom of the one-way channel due to gravity and be discharged through the second flow hole 21, thereby enhancing the gas-liquid separation effect, reducing the amount of liquid carried in the exhaust of the separator, and improving the gas-liquid separation rate, thereby ensuring the energy efficiency of the compressor.

[0065] Considering the outflow scheme of the gaseous fluid in the cylinder 3 in the first gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the gas-liquid separation partition also includes a first tube 6, which is inserted into the cylinder 3 through the second partition 2 so that the space below the second partition 2 is connected to the inner cavity of the cylinder 3 through the first tube 6.

[0066] In this way, by adding a first tube 6 and inserting it into the cylinder 3 through the second partition 2, the space below the second partition 2 is connected to the inner cavity of the cylinder 3, forming a directional exhaust channel, which can provide an exclusive and stable outflow path for the gaseous fluid separated in the cylinder 3. Compared with the non-directional structure, it reduces the disordered diffusion and energy loss of the airflow in the liquid separator, allowing the gaseous fluid to flow out with lower resistance and more uniform flow rate, thereby reducing the system pressure drop.

[0067] For example, the first tube 6 adopts a straight tube structure, that is, it achieves the effect of vertical insertion. Combined with the overall structure of the gas-liquid separation partition, the gas-liquid separation effect is further enhanced by utilizing the principles of gravity and fluid mechanics. The residual liquid refrigerant is more likely to slide along the tube wall to the bottom of the second partition 2 due to the action of gravity and be discharged, effectively avoiding the secondary mixing of liquid refrigerant.

[0068] Considering the first gas-liquid separation path, the first tube 6 can be used to smoothly flow out the gaseous fluid. In the gas-liquid separation partition provided in the embodiment of the present application, the end of the first tube 6 used to extend into the interior of the cylinder 3 is located in the upper area of ​​the cylinder 3.

[0069] In this way, the end of the first tube 6 extending into the interior of the cylinder 3 is set in the upper area of ​​the cylinder 3, which can form an efficient gaseous fluid derivation path; since the liquid refrigerant is mostly deposited in the lower part of the cylinder 3 under the action of gravity, the gaseous fluid in the upper area has higher purity, and the end of the first tube 6 is located in this area, which can preferentially extract pure gaseous refrigerant, greatly reducing the amount of liquid carried in the exhaust, and compared with the traditional random derivation method, the gas-liquid separation efficiency can be improved; this layout shortens the rising path of the gaseous fluid in the cylinder 3, reduces the flow resistance, makes the fluid flow smoother, reduces the system pressure drop, and improves the compressor suction efficiency.

[0070] Considering the second gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the first flow hole 11 is used to connect the space above the first partition 1 with the inner cavity of the cylinder 3; the second flow hole 21 is used to connect the inner cavity of the cylinder 3 with the lower space of the second partition 2; the third flow hole 31 is used to connect the inner cavity of the cylinder 3 with the one-way channel; the gas-liquid mixed fluid is configured to flow to the inner cavity of the cylinder 3 through the first flow hole 11, and perform a liquid deposition in the inner cavity of the cylinder 3; the gas-liquid mixed fluid flows to the one-way channel through the third flow hole 31, and performs a secondary liquid deposition in the one-way channel, and then the gaseous fluid flows out through the second flow hole 21.

[0071] In this way, an efficient separation mechanism of "two-stage gradient separation + three-dimensional space utilization" is constructed, which significantly improves the gas-liquid separation performance and system stability; through two-stage deposition, the separation efficiency is broken through: the gas-liquid mixed fluid directly enters the inner cavity of the cylinder 3 through the first flow hole 11, and the vertical space of the cylinder 3 is used to form the first gravity separation. The liquid refrigerant with larger particle size quickly settles to the inner wall of the cylinder 3 due to gravity and slides to the top of the second partition 2; the residual gas-liquid mixed fluid cuts into the one-way channel horizontally through the third flow hole 31, and due to the sudden expansion of the channel cross-sectional area and the change of flow direction, secondary inertial separation is triggered. The tiny droplets complete the secondary deposition due to the collision of the wall and the sudden drop in flow rate, and the two-stage separation is completed. The overall separation efficiency is improved and the amount of liquid carried over from exhaust can be significantly reduced; the flow state is then optimized and energy consumption is significantly reduced: the path design allows the fluid to flow in a vertical laminar manner in the inner cavity of the cylinder 3 and flow horizontally and slowly in the one-way channel, effectively suppressing the generation of turbulence, reducing the overall pressure drop of the system, reducing the suction resistance of the compressor, improving the volumetric efficiency, and improving the energy efficiency ratio of the system; at the same time, the stable flow state reduces the fluid impact noise, and the noise value is lower than that of traditional liquid separators; combined with the integrated molding process, the structural deformation resistance is improved; the two-stage separation path reduces the load pressure of a single flow channel, avoids structural fatigue caused by local liquid accumulation, extends the service life, and ensures long-term stable operation of the system.

[0072] Considering the position scheme of the first flow hole 11 in the second gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the first flow hole 11 is located in the middle area of ​​the first partition 1, and the first flow hole 11 is located in the barrel mouth area of ​​the barrel 3.

[0073] In this way, it can be ensured that in the second gas-liquid separation path solution, the space above the first partition plate 1 is connected to the inner cavity of the cylinder 3 through the first flow hole 11.

[0074] Considering how to achieve the connection between the first partition 1 and the inner cavity of the cylinder 3 through the first flow hole 11 in the second gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the gas-liquid separation partition also includes a second tube 13, and the second tube 13 is inserted into the cylinder 3 through the first flow hole 11, so that the space above the first partition 1 is connected with the inner cavity of the cylinder 3 through the second tube 13.

[0075] In this way, by adding a second tube 13 and inserting it into the inner cavity of the cylinder 3 through the first flow hole 11, a specific diversion channel is obtained, the flow direction of the gas-liquid mixed fluid is accurately controlled, the turbulence caused by impact is avoided, the initial separation efficiency of the liquid refrigerant is improved, and the subsequent separation load is reduced; at the same time, the second tube 13 forms a nested support structure with the partition and the cylinder 3, which enhances the overall rigidity, improves the deformation resistance, and reduces the vibration noise; in addition, the stable diversion reduces the flow resistance, reduces the compressor suction energy consumption, improves the energy efficiency ratio, ensures the stability of the gas-liquid separation efficiency, and comprehensively improves the performance of the liquid separator and the reliability of the system operation.

[0076] Considering that the positioning scheme of the second tube 13 can smoothly facilitate the liquid deposition of the gas-liquid mixed fluid in the cylinder 3, in the gas-liquid separation partition provided in the embodiment of the present application, the end of the second tube 13 used to extend into the interior of the cylinder 3 is located in the lower area of ​​the cylinder 3.

[0077] In this way, after the gas-liquid mixed fluid enters the cylinder 3, it quickly contacts the bottom of the cylinder 3 by virtue of gravity, and the liquid refrigerant can begin to settle at a lower height, greatly shortening the liquid deposition path, improving the deposition efficiency, and effectively reducing the probability of the liquid refrigerant entering the one-way channel with the gaseous fluid; secondly, the diversion design of the lower area cooperates with the structure of the cylinder 3 to guide the gas-liquid mixed fluid to form a spiral upward flow state, and the liquid refrigerant is accelerated to separate under the dual action of centrifugal force and gravity, further strengthening the initial separation effect, and the gas-liquid separation rate can be further improved; furthermore, the low-position access method of the second pipe 13 reduces the risk of the fluid impacting the top of the cylinder 3, reduces the vibration and noise caused by the impact, reduces the vibration amplitude, and reduces the operating noise; in addition, it can also enable the gas-liquid separation partition to maintain stable performance under high liquid content conditions, and the rapid deposition of liquid refrigerant avoids excessive liquid accumulation inside the cylinder 3, ensuring the reliability of the system under all working conditions.

[0078] Considering the position scheme of the second flow hole 21 in the second gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the second flow hole 21 is located in the middle area of ​​the second partition 2, and the second flow hole 21 is located in the bottom area of ​​the cylinder 3.

[0079] In this way, it can be ensured that in the second airflow separation path, the second through-hole 21 can communicate between the cylinder 3 and the lower space of the second partition plate 2.

[0080] Considering how to realize the connection between the one-way channel and the space below the second partition 2 through the second flow hole 21 in the second gas-liquid separation path scheme, in the gas-liquid separation partition provided in the embodiment of the present application, the gas-liquid separation partition also includes a third tube 23, and the third tube 23 is inserted between the one-way channel and the second partition 2 through the second flow hole 21, so that the space below the second partition 2 is connected to the one-way channel through the third tube 23.

[0081] In this way, by adding a third tube 23 and connecting the one-way channel to the space below the second partition 2 through the second flow hole 21, an efficient guide channel is constructed. The third tube 23 forms a specific outlet path for the gaseous fluid, avoiding disordered flow of the fluid in the liquid separator, reducing the risk of secondary entrainment of liquid refrigerant caused by airflow disturbance, and reducing the amount of liquid carried in the exhaust; at the same time, the fluid flow path is optimized, the flow resistance is reduced, the system pressure drop is reduced, the compressor suction efficiency is improved, and the system energy efficiency ratio is improved; further, the combined structure of the third tube 23, the partition and the channel enhances the overall stiffness of the gas-liquid separation partition, reduces the vibration caused by the impact of the airflow, and the third tube 23 is designed to adapt to liquid separators of different specifications. Under various working conditions such as heat pumps and refrigeration, the gas-liquid separation efficiency can be guaranteed to be stable, thereby improving the equipment operation reliability.

[0082] Considering that the positioning scheme of the third tube 23 can smoothly facilitate the deposition of the gas-liquid mixed fluid in the one-way channel, the gaseous fluid can then flow from the upper space through the third tube 23 to the lower space of the second partition 2. In the gas-liquid separation partition provided in the embodiment of the present application, one end of the third tube 23 used to extend into the one-way channel is located in the upper area of ​​the one-way channel.

[0083] In this way, the pure gaseous fluid after deposition in the one-way channel can be quickly discharged through the third tube 23 located in the upper area with minimal interference, effectively avoiding stirring of the liquid refrigerant deposited at the bottom of the channel when extracting the gaseous fluid, reducing the risk of secondary entrainment, and further reducing the amount of liquid carried over by exhaust gas; at the same time, the discharge path in the upper area shortens the flow distance of the gaseous fluid, reduces flow resistance, reduces system pressure drop, and improves the suction efficiency of the compressor.

[0084] Considering the formation scheme of the one-way channel, the radial dimensions of the first partition plate 1 and the second partition plate 2 are larger than the radial dimension of the cylinder 3 .

[0085] In this way, the formation of a one-way channel can be ensured, and a specific gas-liquid separation path can be obtained.

[0086] Further considering the formation scheme of the one-way channel, a partition plate 4 is provided between the outer wall of the cylinder 3, the first partition plate 1 and the second partition plate 2, so as to form the one-way channel between the gas-liquid separation partition and the inner wall of the liquid separator.

[0087] In this way, with the setting of the partition plate 4, the fluid will not have the problem of disorderly flow in the channel where the outer wall of the cylinder 3 is located, and a one-way channel can be obtained, thereby ensuring the single flow direction of the fluid in the one-way channel.

[0088] In summary, in the first scheme, the flow holes of the first partition 1 and the flow holes of the second partition 2 are respectively located on both sides of the partition plate 4, and the refrigerant enters the double-layer partition through the first flow hole 11 of the first partition 1. Due to the staggered placement of the cylinder 3, the partition plate 4 and the upper and lower flow holes, the refrigerant needs to circle the cylinder 3 for about one circle after entering the partition. When it reaches the second flow hole 21 of the second partition 2, the liquid refrigerant leaves the partition through the second flow hole 21 of the second partition 2 due to gravity, while the gaseous refrigerant enters the cylinder 3 through the third flow hole 31 on the side wall of the cylinder 3, thereby achieving the effect of gas-liquid separation.

[0089] Further combined with the first solution, the first tube 6 passes through the first hole 22, and the top end is placed in the middle of the cylinder 3 close to the first partition 1. Since the first partition 1 has no perforations, the liquid refrigerant is prevented from directly entering the first tube 6; at the same time, when the gaseous refrigerant carries a small amount of liquid refrigerant into the cylinder 3, since the upper end of the first tube 6 is close to the first partition 1, a small amount of liquid refrigerant entering the cylinder 3 can also be prevented from entering. The liquid refrigerant accumulated in the cylinder 3 will be discharged from the cylinder 3 when it reaches the height of the third flow hole 31 on the side wall of the cylinder 3, and then discharged from the partition through the second flow hole 21 of the second partition 2.

[0090] Similarly, the second partition 2 of the integrated gas-liquid separation partition corresponding to the twin-cylinder compressor has two through holes and two straight tubes, and its gas-liquid separation principle remains unchanged.

[0091] Similarly, regarding the second integrated gas-liquid separation partition scheme, after the refrigerant enters the liquid separator, the gaseous refrigerant enters the interior of the cylinder 3 through the second tube 13, and the small amount of liquid refrigerant brought in accumulates at the bottom of the cylinder 3. The gaseous refrigerant reaches the upper space of the cylinder 3, and reaches the outside of the cylinder 3 through the third flow hole 31 on the side wall of the cylinder 3. Under the action of the partition plate 4, it circles around the cylinder 3. The liquid refrigerant accumulates at the lower bottom of the outside of the cylinder 3 due to gravity. The gaseous refrigerant is discharged from the partition through the third tube 23, and then enters the compressor to participate in operation, realizing gas-liquid separation.

[0092] It should be pointed out that the integrated gas-liquid separation partition has a double-layer partition, and the flow holes of the two partitions are located on both sides of the partition. After the refrigerant enters the liquid separator, it needs to go around the cylinder 3 for a circle, which increases the gas-liquid separation path, while improving the rigidity of the liquid separator and reducing vibration noise; the cylinder 3 is set between the two partitions of the integrated gas-liquid separation partition, and the side of the cylinder 3 is opened. The liquid refrigerant enters the flow hole of the lower partition due to gravity, and the gaseous refrigerant enters the cylinder 3, further realizing gas-liquid separation and improving the gas-liquid separation rate; the top end of the straight tube of the integrated gas-liquid separation partition is placed below the upper partition and inside the cylinder 3 in the middle of the double-layer partition to avoid the liquid refrigerant from directly entering the straight tube and reduce the amount of liquid in the exhaust of the liquid separator; the liquid separator can reduce the amount of liquid refrigerant entering the straight tube. During the operation of the compressor, when there is too much liquid refrigerant, the straight pipe inside the liquid separator can prevent the liquid refrigerant from directly entering the pump body and prevent liquid hammer. The use of an integrated gas-liquid separation partition can reduce the situation of liquid refrigerant entering the straight pipe, while not affecting the smooth entry of gaseous refrigerant into the straight pipe. It can reduce the amount of liquid carried by the liquid separator exhaust, improve the gas-liquid separation rate, stabilize the airflow, reduce noise and vibration, and improve the energy efficiency of the compressor.

[0093] The present application further provides a liquid separator, comprising the aforementioned gas-liquid separation baffle and a housing 7, wherein the gas-liquid separation baffle is installed in the housing 7 and forms the one-way channel with the inner wall of the housing 7. The separator can achieve all the effects of the aforementioned gas-liquid separation baffle, which will not be described in detail here.

The full effects of the above-mentioned dispenser can be achieved and will not be described in detail here.
