[0001] This application relates to the field of liquid dispenser technology, and more specifically, to a liquid dispenser and a compressor having therein. Background Technology

[0002] Currently, in existing refrigeration systems, the distributor is a key component, and its performance directly affects the system's cooling effect and energy efficiency ratio. Specifically, most existing distributors adopt a straight-through liquid distribution method, that is, the refrigerant enters the distributor directly from the inlet and is distributed to various outlets through a simple diversion structure.

[0003] However, existing liquid separators often suffer from poor gas-liquid separation, which in turn increases the risk of liquid slugging. Utility Model Content

[0004] The main objective of this application is to provide a liquid separator and a compressor having the same, in order to solve the technical problem of poor gas-liquid separation effect of liquid separators in the prior art.

[0005] To achieve the above objectives, according to one aspect of this application, a liquid dispenser is provided, comprising: A housing having an inlet, an outlet, and a mounting cavity communicating with both the inlet and the outlet; A liquid outlet pipe is inserted at the outlet, and at least a portion of the liquid outlet pipe extends into the mounting cavity. The liquid separating plate is sleeved on the liquid outlet pipe and fixedly connected to the housing; the liquid separating plate extends spirally along the extension direction of the liquid outlet pipe.

[0006] Furthermore, at least a portion of the outer periphery of the liquid distribution plate is fixedly connected to the inner wall of the housing; and / or, The separatory plate is provided with a reinforcing coating.

[0007] Furthermore, an installation groove is provided on the inner wall of the housing, and at least a portion of the outer periphery of the liquid separator is installed in the installation groove.

[0008] Furthermore, the mounting groove is a spiral groove adapted to the liquid distribution plate; and / or, The outer periphery of the liquid separator is snapped or welded into the mounting groove.

[0009] Furthermore, along the extension direction from the outlet pipe to the outer periphery of the distribution plate, the height of the longitudinal section of the distribution plate gradually decreases in the axial direction; or, Along the direction of extension from the liquid outlet pipe to the outer periphery of the liquid distribution plate, the longitudinal section of the liquid distribution plate is at the same height in the axial direction of the liquid distribution plate.

[0010] Furthermore, the angle between the side of the liquid separator closest to the inlet and the horizontal plane is the refrigerant incident angle α, where 15°≤α≤30°.

[0011] Furthermore, when the refrigerant is R32, 23°≤α≤26°; When the refrigerant is R290, 29°≤α≤32°; When the refrigerant is R454B, 18°≤α≤20°; When the refrigerant is CO2, 20°≤α≤22°.

[0012] Furthermore, the surface of the separatory plate is coated with a diamond carbon film; and / or, There are at least two liquid outlet pipes, which are spaced apart, and the liquid distribution plate is sleeved on the at least two liquid outlet pipes.

[0013] Furthermore, the included angle between the two sides of the separator along the axial direction is the spiral rise angle β, 15°≤β≤30°; and / or, The separatory plate is equipped with a flow guide groove.

[0014] According to another aspect of this application, a compressor is provided, including the liquid dispenser provided above.

[0015] By applying the technical solution of this application, gas-liquid separation can be effectively achieved by increasing the contact area between the distributor plate and the fluid in the mounting cavity, combined with a spiral arrangement, thus enhancing the gas-liquid separation effect. The use of a reinforcing coating further enhances the structural stability and corrosion resistance of the distributor plate, extending the service life of the distributor. Specific angle adjustments for different refrigerants allow the distributor to adapt to various working environments, improving its versatility and applicability. Furthermore, the design of multiple liquid outlet pipes increases the fluid separation path, improving the overall performance of the equipment. These improvements work together to significantly enhance the separation effect of the distributor, playing a crucial role in improving the compressor's efficiency and reliability.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3 As shown, an embodiment of this application provides a liquid separator, which includes: a housing 10, an outlet pipe 20, and a liquid separator plate 30. The housing 10 has an inlet 11, an outlet 12, and a mounting cavity 13 communicating with both the inlet 11 and the outlet 12. The outlet pipe 20 is inserted at the outlet 12, and at least a portion of the outlet pipe 20 extends into the mounting cavity 13. The liquid separator plate 30 is sleeved on the outlet pipe 20 and fixedly connected to the housing 10. The liquid separator plate 30 extends spirally along the extending direction of the outlet pipe 20.

[0020] The liquid separator provided in this embodiment, by employing a spirally arranged liquid separator plate 30 structure, effectively increases the contact area between the liquid separator plate 30 and the fluid in the mounting cavity 13. Combined with the spiral arrangement, this effectively enhances the gas-liquid separation effect, allowing for better separation of the liquid from the fluid. Specifically, the liquid separator plate 30 can be understood as a rotating baffle. This structure significantly increases the contact area with the fluid, thereby expanding the improved airflow distribution within the fixed mounting cavity 13 space, increasing separation efficiency, and optimizing airflow characteristics.

[0021] Specifically, at least a portion of the outer periphery of the liquid distribution plate 30 is fixedly connected to the inner wall of the housing 10. Compared to a flat plate structure, the liquid distribution plate 30 in this application is spirally arranged, which increases the contact area between the liquid distribution plate 30 and the housing 10. This is equivalent to increasing the "landing point" area for liquid sedimentation, allowing more liquid to settle to the bottom, reducing the possibility of escape with the airflow, improving liquid collection efficiency, and enhancing the separation effect. Simultaneously, the increased contact area between the liquid distribution plate 30 and the housing 10 means that the liquid distribution plate 30 and the housing 10 are more firmly bonded, less prone to deformation or loosening under high pressure or high flow rate conditions, improving connection strength, reducing gap leakage, and enhancing the sealing performance of the liquid distributor. The entire structure is more adaptable to complex working conditions. The altered partition affects the stiffness and mass distribution of the liquid distributor, thereby changing its modal characteristics and increasing the modal frequency, moving it away from the operating frequency range, effectively avoiding resonance, thus reducing noise, reducing vibration, and improving sound transmission.

[0022] Specifically, an inlet pipe 40 is installed on inlet 11.

[0023] The liquid distribution plate 30 is provided with a reinforcing coating to improve the structural strength of the liquid distribution plate 30 and reduce the susceptibility of the liquid distribution plate 30 to corrosion.

[0024] The fixed connection between the distributor plate 30 and the housing 10 ensures the stability of the distributor plate 30 within the housing 10, preventing displacement during refrigerant flow and thus avoiding impact on separation efficiency. The reinforcing coating enhances the structural strength of the distributor plate 30 and extends its service life. In principle, the reinforcing coating improves the corrosion resistance and wear resistance of the distributor plate 30, maintaining good performance over long-term use. In terms of effectiveness, the technology in this embodiment improves the reliability and durability of the distributor, reducing maintenance costs. In other embodiments, the stability and durability of the distributor plate 30 can be further improved by increasing the contact area between the distributor plate 30 and the housing 10 or by changing the material of the reinforcing coating.

[0025] Specifically, a mounting groove 14 is provided on the inner wall of the housing 10, and at least a portion of the outer periphery of the distributor plate 30 is installed in the mounting groove 14. The mounting groove 14 provides more precise positioning for the distributor plate 30, ensuring its fixed position within the housing 10. In principle, the mounting groove 14 is adapted to the outer periphery of the distributor plate 30, enabling the distributor plate 30 to be fixed by snap-fit ​​or welding, thus improving its structural stability. In terms of effect, the technology in this embodiment makes the installation of the distributor plate 30 within the housing 10 more secure, preventing displacement during refrigerant flow and ensuring effective refrigerant separation. In other embodiments, the fixing effect of the distributor plate 30 can be further improved by optimizing the shape of the mounting groove 14 or increasing its depth.

[0026] Furthermore, the mounting groove 14 is a spiral groove adapted to the dispensing plate 30. Specifically, the spiral groove can be understood as a stepped threaded groove structure, which allows the outer periphery of the dispensing plate 30 to be engaged within the mounting groove 14, thus significantly improving the rigidity of the entire dispensing device.

[0027] The outer periphery of the liquid distribution plate 30 is snapped or welded into the mounting groove 14.

[0028] Specifically, the mounting groove 14 of the spiral groove can better match the spirally extended distributor plate 30, improving the installation accuracy and stability. In principle, fixing the distributor plate 30 by snap-fit ​​or welding ensures that it will not shift during refrigerant flow, maintaining a good separation effect. In terms of effect, the technology in this embodiment makes the connection between the distributor plate 30 and the housing 10 more secure, improving the reliability of the distributor and the refrigerant separation effect. In other embodiments, the fixing effect of the distributor plate 30 can be further optimized by changing the specific snap-fit ​​or welding method, such as using different types of clips or welding materials.

[0029] Specifically, the mounting groove 14 is a spiral groove, and the housing 10 of the separator is configured with a detachable upper end cover, a cylinder, and a lower end cover. The upper end cover is provided with an inlet pipe 11, which can be a straight pipe, and the lower end cover is provided with two outlet pipes 12, which can be bent pipes. During installation, the spiral dispensing plate 30 is screwed into the cylinder, and the outer ring of the spiral dispensing plate 30 mates with the inner ring threaded groove of the cylinder. Then, the upper end cover and the lower end cover are assembled together with the cylinder.

[0030] Furthermore, along the extension direction from the outlet pipe 20 to the outer periphery of the distribution plate 30, the height of the longitudinal section of the distribution plate 30 gradually decreases in the axial direction of the distribution plate 30; or, along the extension direction from the outlet pipe 20 to the outer periphery of the distribution plate 30, the longitudinal section of the distribution plate 30 is at the same height in the axial direction of the distribution plate 30.

[0031] Specifically, gradually decreasing or maintaining the same height of the distributor plate 30 can affect the flow path and velocity of the refrigerant within the housing 10, thereby optimizing the refrigerant separation effect. In principle, changes in height can alter the flow characteristics of the refrigerant on the distributor plate 30; for example, decreasing the height increases the refrigerant flow velocity, while maintaining the same height ensures uniform flow of the refrigerant on the distributor plate 30. In terms of effect, the technology in this embodiment enables a more uniform distribution of refrigerant at the liquid outlet pipe 20, improving the compressor's operating efficiency and stability. In other embodiments, the refrigerant separation effect can be further optimized by adjusting the height change rate of the distributor plate 30 or by using distributor plates 30 of other shapes.

[0032] Furthermore, the angle between the side of the distribution plate 30 near the inlet 11 and the horizontal plane is the refrigerant incident angle α, where 15°≤α≤30°. The setting of the refrigerant incident angle α can affect the flow direction of the refrigerant when it enters the housing 10, thereby affecting its distribution on the distribution plate 30. In principle, by adjusting the refrigerant incident angle α, the flow path and velocity of the refrigerant within the housing 10 can be controlled, achieving better separation. In terms of effect, the technology in this embodiment enables the refrigerant to form a more reasonable flow pattern when entering the housing 10, improving its separation effect and reducing local overheating or undercooling. In other embodiments, the refrigerant separation effect can be further improved by optimizing the specific value of the refrigerant incident angle α. In particular, for different refrigerants of the same model, the internal incident angle of the distributor is different due to the different physical properties of the refrigerant. Conventionally, the corresponding distributor needs to be redesigned. However, in this application, by adding a corresponding threaded distribution plate 30 inside the distributor cylinder, the refrigerant incident angle is made within the above range, thus enabling it to be adapted to multiple different models and different refrigerants.

[0033] Specifically, the spiral ascent angle of the separator 30 can be set differently for different refrigerants. When the refrigerant is R32, 23°≤α≤26°; when the refrigerant is R290, 29°≤α≤32°; when the refrigerant is R454B, 18°≤α≤20°; and when the refrigerant is CO2, 20°≤α≤22°. This setting better adapts to different refrigerant types and improves the separation effect for those types. Specifically, different angles can be adjusted according to different refrigerants, as different incident angles have different effects in the centrifugal separation zone, thus allowing different ascent angles to be matched with the corresponding refrigerants.

[0034] Specifically, when the refrigerant is Freon, it corresponds to R32. When the refrigerant is R290, it corresponds to propane. R454B is a mixed refrigerant. When the refrigerant is CO2, it corresponds to carbon dioxide.

[0035] Setting different refrigerant incident angles α for different types of refrigerants allows for more precise control of refrigerant flow characteristics and achieves optimized separation. In principle, different refrigerants have different physical properties (such as viscosity and density), therefore their flow characteristics within the casing 10 will also differ. Adjusting the refrigerant incident angle α can better adapt to the flow requirements of different refrigerants. In terms of effect, the technology in this embodiment enables the distributor to achieve good refrigerant separation when using different refrigerants, improving the versatility and adaptability of the compressor. In other embodiments, further research into the flow characteristics of different refrigerants can optimize the setting range of the refrigerant incident angle α, further improving the refrigerant separation effect.

[0036] Furthermore, the surface of the liquid distribution plate 30 is provided with a diamond carbon film coating; and / or, there are at least two liquid outlet pipes 20, which are spaced apart, and the liquid distribution plate 30 is sleeved on the at least two liquid outlet pipes 20.

[0037] The diamond carbon film coating improves the surface hardness and wear resistance of the distributor plate 30, extending its service life. The number and spacing of the outlet pipes 20 affect the refrigerant separation path and efficiency. In principle, the diamond carbon film coating reduces the frictional resistance of the refrigerant on the distributor plate 30, improving its flow efficiency. Multiple outlet pipes 20 increase the refrigerant separation path, improving separation efficiency. In effect, the technology in this embodiment enables the distributor to maintain good performance during long-term use, improving refrigerant separation efficiency and uniformity. In other embodiments, the wear resistance of the distributor plate 30 and its service life can be further improved and extended by changing the thickness of the diamond carbon film coating or using other types of wear-resistant coatings.

[0038] Furthermore, the included angle between the two sides of the liquid distribution plate 30 along the axial direction is the spiral rise angle β, where 15°≤β≤30°. The setting of the spiral rise angle β can affect the spiral extension characteristics of the liquid distribution plate 30 within the housing 10, thereby affecting the refrigerant separation path and effect. In principle, by adjusting the spiral rise angle β, the flow direction and speed of the refrigerant within the housing 10 can be controlled, achieving better separation. In terms of effect, the technology in this embodiment can make the flow path of the refrigerant within the housing 10 more reasonable, improving the separation effect. In other embodiments, the refrigerant separation effect can be further improved by optimizing the specific value of the spiral rise angle β.

[0039] The distributor in this application enhances its rigidity, reduces vibration amplitude, improves compressor noise transmission, and reduces resonance between the distributor and the compressor body. The new structure also improves the distributor's filtration function, enhancing gas-liquid separation. Its structure effectively provides a stable suction environment, reduces refrigerant flow fluctuations, indirectly improves efficiency and reliability, reduces the risk of liquid slugging, maintains superheat, and minimizes liquid refrigerant entering the cylinder. Furthermore, the spiral structure on the cylinder can be adjusted to regulate the angle at which refrigerant gas enters the distributor, enabling the use of corresponding silencers for different refrigerants.

[0040] The stepped spiral-shaped distribution plate 30 significantly enhances the rigidity of the distributor. Simultaneously, the plate guides the refrigerant flow, indirectly improving performance. Furthermore, the centrifugal force of the structure significantly improves gas-liquid separation. The threaded mounting groove 14 on the housing 10 provides adjustable incident angles. Unlike existing distributors where the partitions are welded together, this design uses a spiral snap-fit ​​connection, allowing for adjustment of the incident angle for different refrigerants, thus enabling a single distributor to serve multiple purposes.

[0041] Preferably, in one embodiment, the incident angle is 21° and the spiral ascent angle is 29°.

[0042] Compared to the flat liquid distribution structure in the prior art, the liquid distribution plate 30 structure in this application is equivalent to a longitudinal opening, which increases the lateral contact area and extends the flow path of the refrigerant. At the same time, its spiral structure is designed to minimize material consumption and also provides centrifugal force for the gas-liquid mixture.

[0043] Based on the formula Fc=mω 2 Regarding r (Fc is centrifugal force), (where r is the angular velocity, r is the radius of curvature, and m is the mass). Here, the radius and the angle of spiral ascent can be adjusted to define the specific structure of the spiral. For example, for R290 refrigerant, the spiral angle should be increased to reduce the rotation speed and prevent excessive flow rate from causing combustion.

[0044] Specifically, gas is drawn into the distributor through the inlet pipe. After passing through the filter layer, part of the gas-liquid mixture enters the compressor directly through the steel pipe (outlet pipe), but most of it enters the cylinder. Inside the cylinder, it evaporates and re-enters the steel pipe. This application proposes a spiral separator structure, which allows for better gas-liquid separation within the spiral wall. Simultaneously, the spiral wall provides a guiding effect, combining better liquid storage and separation, offering a good evaporation space, and accelerating the oil return effect of the distributor. After condensation, some lubricating oil enters the distributor along with the refrigerant. The spiral separator 30 guides the refrigerant through the oil return hole at the bottom of the distributor. The lubricating oil is guided to the compressor by gravity and airflow. At this point, the baffle separates the internal space of the cylinder, providing a good evaporation space as described in the original text, thereby achieving the oil return function.

[0045] like Figure 4 and Figure 5As shown, five compressors were randomly selected for testing to verify the new structural design and the original design, focusing on both upward rocking vibration and upward radial vibration. The modal analysis clearly shows that the new distributor exhibits a lower frequency of free vibration at the same order, demonstrating its effectiveness in addressing the issue of transmitted noise. The spiral baffle (corresponding to the dispensing plate 30) and the cylinder with the spiral ring (corresponding to the mounting groove 14) work together to increase the contact area, reduce the risk of system resonance, and improve operational stability. Simultaneously, they optimize the natural frequency distribution, avoiding the risk of overlapping key frequencies and resonance, thus reducing the transmission of vibration.

[0046] Specifically, the cross-sectional shape of the separating plate 30 can be changed, making it an isosceles triangle with circumferentially cut partitions, or a regular quadrilateral structure. The advantages of a regular quadrilateral structure are also obvious: it increases the longitudinal contact surface with the separator cylinder. With appropriate adjustments, while ensuring the effective volume of the separator, its rigidity is effectively improved, greatly reducing the frequent transmission noise problem. Furthermore, its spiral tendency effectively utilizes the centrifugal effect of the gas-liquid mixture, unlike the original mass-produced flat baffle which only achieves separation through wall contact. Its gas-liquid separation effect is also significant. This application should protect the patent for only changing the shape of the spiral structure's contact surface.

[0047] In other embodiments, a flow guide groove structure can be added to the spiral baffle. By adding a flow guide groove of a certain thickness to the spiral surface of the baffle, the flow rate of the gas-liquid mixture is increased, and a collision surface is added, which increases the flow diversion effect. Therefore, changes in the spiral shape should also be protected by this patent.

[0048] According to another embodiment of this application, a compressor is provided, including the liquid separator provided in the above embodiment.

[0049] The compressor in this embodiment, by employing the optimized distributor design described above, can more effectively distribute refrigerant, thereby improving its operating performance. In principle, the optimized distributor design allows for more uniform refrigerant flow within the compressor, improving its refrigeration efficiency and stability. In terms of effect, the technology in this embodiment enables the compressor to be more efficient in refrigerant distribution, reducing energy consumption and improving overall performance. In other embodiments, the refrigeration effect and energy efficiency ratio of the compressor can be further improved by combining other technical solutions, such as optimizing the internal structure of the compressor or improving the refrigerant circulation system.

[0050] The refrigerant enters the mounting cavity 13 of the housing 10 through inlet 11, and forms a spiral flow guided by the spirally extended distribution plate 30. The fixed connection between the distribution plate 30 and the housing 10, and the reinforcement coating, ensure its stability and structural strength within the housing 10. The mounting groove 14 provides more precise positioning, while the variation or equal height of the distribution plate 30 and the setting of the refrigerant incident angle α optimize the refrigerant separation path and speed, improving the separation effect. The diamond carbon film coating improves the wear resistance of the distribution plate 30, and the setting of the spiral rise angle β controls the flow direction and speed of the refrigerant within the housing 10. Ultimately, the distributor of this application enables effective refrigerant separation, improves the compressor's operating efficiency and stability, and enhances overall performance.

[0051] As can be seen from the above description, the embodiments of this application achieve the following technical effects: By adding a corresponding spiral mounting groove structure inside the distributor's housing and adding a corresponding spiral-structured dispensing plate, a new distributor is formed. This distributor has significant advantages; for different refrigerants and different ambient temperatures, the corresponding spiral-structured dispensing plate can be adjusted to change the dispensing plate and incident angle, allowing a single distributor to be applicable to multiple models. It solves the technical problem of excessive compressor noise transmission, reduces compressor vibration, improves the gas-liquid separation effect of the distributor, increases the number of compatible models, and enhances the applicability of the same model to different refrigerants. It reduces compressor noise transmission, lowers the risk of abnormal compressor noise, improves the gas-liquid separation effect of the distributor, lowers the risk of liquid slugging, indirectly improves efficiency and reliability, and reduces costs.
