Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more particularly to a rotary liquid distributor and an air conditioner. Background Technology

[0002] In air conditioning systems, the heat exchange efficiency of the heat exchanger plays a crucial role in the overall system performance. To improve heat exchange efficiency, heat exchangers are often designed with multiple flow channels, such as microchannel heat exchangers or finned tube heat exchangers. In this case, a distributor needs to be installed at the inlet of the heat exchanger to divide the refrigerant flow, allowing each refrigerant path to enter a different flow channel within the heat exchanger.

[0003] To ensure uniform liquid distribution, related liquid separators typically incorporate a rotating impeller at the inlet. The impact of the refrigerant entering the separator drives the impeller to rotate, agitating and turbulent the refrigerant to promote uniform distribution. However, the impeller's agitation effect on the refrigerant is extremely limited, and uneven gas-liquid phase distribution and inconsistent liquid distribution still exist.

[0004] Therefore, how to solve the problem of uneven liquid distribution in the liquid separator in related technologies has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] This invention provides a rotary liquid dispenser and an air conditioner to solve the problem of uneven liquid distribution in related liquid dispensers.

[0006] This invention provides a rotary liquid distributor, comprising a liquid distributor body, an impeller, and a liquid equalization component; The main body of the liquid dispenser is provided with a turbulence chamber and a liquid dispensing chamber. The turbulence chamber is located on the side of the liquid dispensing chamber near the inlet end of the main body of the liquid dispenser, and the end of the liquid dispensing chamber near the turbulence chamber is connected to the turbulence chamber. The impeller and the liquid equalization element are fixed relative to each other and rotatably disposed in the turbulence cavity. The liquid equalization element is located on the side of the impeller close to the liquid distribution cavity. The liquid equalization element has a turbulence part along the circumference of the liquid distributor body. The blades of the impeller are staggered with the turbulence part. There is a gap between the blades of the impeller and the turbulence part for the refrigerant to flow. The main body of the distributor is provided with a connection port for the refrigerant in the dispensing chamber to flow out.

[0007] With this configuration, the refrigerant entering the main body of the distributor needs to pass through the impeller and the liquid equalization component before it can enter the distribution chamber from the turbulence chamber. The impeller and the liquid equalization component increase the disturbance process and the distribution process of the refrigerant, realizing two-stage disturbance and distribution of the refrigerant. This makes the gas-liquid two-phase distribution of the refrigerant more uniform, thus making the distribution more uniform and solving the problem of uneven distribution that exists in rotary distributors in related technologies.

[0008] According to the present invention, a rotary liquid dispenser has a dispensing chamber having at least two sub-chambers, each of the sub-chambers being distributed circumferentially along the main body of the dispenser, and each of the sub-chambers being connected to the turbulence chamber.

[0009] With this configuration, when the main body of the distributor is vertically oriented, the inlets of each sub-chamber are essentially distributed horizontally. The refrigerant at the outlet of the turbulence chamber is evenly distributed horizontally, resulting in a high consistency in the gas-liquid content of the refrigerant at the inlets of each sub-chamber. This improves the consistency of the gas-liquid content of the refrigerant entering each sub-chamber, thereby achieving uniform refrigerant distribution and enhancing the uniformity of liquid distribution in the rotary distributor.

[0010] According to the present invention, a rotary liquid dispenser is provided, wherein the liquid dispensing chamber includes an inner cavity and an outer cavity, both ends of the inner cavity are closed, and the inner cavity includes at least two second sub-chambers, each of the second sub-chambers being distributed circumferentially along the inner cavity; The outer cavity includes at least one first sub-cavity, and at least two first sub-cavities are provided. Each first sub-cavity is located outside the inner cavity near the end of the turbulence cavity. Each first sub-cavity is distributed circumferentially around the inner cavity. Each first sub-cavity is open on the side near the turbulence cavity. The first sub-cavities and the second sub-cavities are connected one-to-one to form the sub-cavities.

[0011] With this configuration, the refrigerant in the turbulence chamber, after being agitated and diverted by the impeller and the liquid equalization component, is immediately diverted to the first sub-chamber of the liquid distribution chamber, avoiding gas-liquid separation of the refrigerant at the outlet of the turbulence chamber due to gravity. During the flow of the refrigerant from the first sub-chamber to the second sub-chamber, there is also a disturbance to the refrigerant, which promotes a uniform distribution of the gas and liquid phases.

[0012] According to a rotary liquid dispenser provided by the present invention, the outer cavity further includes an annular flow channel, the annular flow channel being located on the side of the first sub-chamber away from the turbulence cavity, at least two annular flow channels are provided, each annular flow channel is arranged around the outside of the inner cavity, each annular flow channel is distributed along the axial direction of the inner cavity, the annular flow channel is connected to the second sub-chamber in a one-to-one correspondence, and the connection port is provided on the side wall of the annular flow channel away from the second sub-chamber.

[0013] With this configuration, when the main body of the distributor is vertically oriented, each annular flow channel is horizontally oriented. The refrigerant flows from the second sub-chamber to the annular flow channel through the second connecting hole, and then flows horizontally within the annular flow channel. The refrigerant's movement through the second connecting hole also causes disturbance, which helps to promote a uniform distribution of the gas-liquid two-phase refrigerant.

[0014] According to the present invention, a rotary liquid dispenser is provided in which the opposite ends of the inlet end of the liquid dispenser body are closed, the connection port is provided on the side wall of the liquid dispenser body, and at least two connection ports are provided, each connection port corresponding to one of the sub-chambers.

[0015] This design, with its annular flow channel, allows the refrigerant to flow and exit horizontally, reducing gas-liquid separation within the channel. Furthermore, even if gas-liquid separation does occur, the separated gas rises vertically rather than converging at specific cross-sections of the annular flow channel (where a cross-section refers to the plane perpendicular to the refrigerant's flow velocity). This ensures high consistency in the gas-liquid content across different cross-sections of the annular flow channel, resulting in uniform gas-liquid content in the refrigerant exiting the connection point at different times. This allows the refrigerant to enter the heat exchanger evenly, improving its heat exchange efficiency and reducing temperature fluctuations.

[0016] According to the present invention, a rotary liquid dispenser is provided in which each of the connection ports is spaced apart along the axial direction of the inner cavity.

[0017] With this configuration, in the existing technology, the inlets of each flow path of the heat exchanger are also distributed in a straight line, so that all the connection ports are located on the same straight line. This allows each connection port of the rotary distributor to be connected to each flow path inlet of the heat exchanger in a one-to-one correspondence. This avoids the need to install connecting pipes between the rotary distributor and the heat exchanger, and allows the refrigerant diverted by the rotary distributor to directly enter the heat exchanger.

[0018] According to the present invention, a rotary liquid dispenser has an annular cross-section for the outer cavity, and each first sub-chamber has a first sidewall and a second sidewall distributed circumferentially along the outer cavity. In each first sub-chamber, the included angle between the first sidewall and the second sidewall corresponding to any two of them is equal. The cross-section of the inner cavity is circular, and each second sub-cavity has a third sidewall and a fourth sidewall distributed circumferentially along the inner cavity. In each second sub-cavity, the included angle between the third sidewall and the fourth sidewall corresponding to any two is equal.

[0019] With this configuration, the cross-sectional shape and size of each first sub-chamber are identical, as are the cross-sectional shape and size of each second sub-chamber. At any given moment, the volume of refrigerant entering each of the first and second sub-chambers is consistent. This consistent volume of refrigerant entering each flow path of the heat exchanger at any given time helps improve the consistency of heat exchange efficiency across the heat exchanger and provides uniform temperature across the heat exchanger surface.

[0020] According to the present invention, a rotary liquid dispenser has a turbulence-distributing portion having a first edge and a second edge distributed circumferentially along the outer cavity, wherein the included angle between the first edge and the second edge of the turbulence-distributing portion is equal to the included angle between the first sidewall and the second sidewall of the first sub-chamber.

[0021] With this configuration, the cross-sectional shape of each individual turbulence section of the liquid equalization component matches that of a single first sub-chamber, allowing the liquid equalization component to intermittently drive the refrigerant in the turbulence chamber into the first sub-chamber. Furthermore, this facilitates better equalization of pressure loss in different sub-chambers within the liquid distribution chamber.

[0022] According to the present invention, the rotary liquid dispenser has a circular orifice or a strip-shaped orifice that extends circumferentially along the main body of the liquid dispenser.

[0023] With this configuration, the shape of the connection port can be set according to the shape of each flow path inlet of the heat exchanger. The circular hole can be adapted to the connection of the finned tube heat exchanger, and the strip hole can be adapted to the connection of the microchannel heat exchanger.

[0024] The present invention also provides an air conditioner, including the rotary distributor as described above.

[0025] The rotary distributor provided by this invention includes a distributor body, an impeller, and a liquid equalization component. The inlet end of the distributor body is used for the refrigerant to be divided. The distributor body has a turbulence chamber and a liquid equalization chamber inside. The turbulence chamber is located on the side of the liquid equalization chamber near the inlet end of the distributor body, and the end of the liquid equalization chamber near the turbulence chamber is connected to the turbulence chamber. After the refrigerant enters the distributor body, it first passes through the turbulence chamber and then enters the liquid equalization chamber for distribution. The impeller and the liquid equalization component are relatively fixed, and both the impeller and the liquid equalization component are rotatably arranged in the turbulence chamber. The impeller and the liquid equalization component can rotate synchronously relative to the distributor body to agitate the refrigerant. The liquid equalization component is located on the side of the impeller near the liquid equalization chamber and has a turbulence-generating portion. Along the circumference of the distributor body, the blades of the impeller and the turbulence-generating portion are staggered, and there is a gap between the blades of the impeller and the turbulence-generating portion for refrigerant flow. When the refrigerant enters the turbulence chamber, it impacts the impeller, generating torque on the impeller blades. This causes the impeller to rotate relative to the distributor body, and the equalizing element rotates synchronously with the impeller. The refrigerant acting on the impeller is disturbed by the impeller and can flow through the gap between the impeller and the turbulence section of the equalizing element to the space between adjacent turbulence sections of the equalizing element, completing the first separation. The refrigerant located between adjacent turbulence sections of the equalizing element is disturbed by the equalizing element and can flow into the distribution chamber for a second separation. The distributor body is provided with a connection port for the refrigerant to flow out of the distribution chamber. With this configuration, the refrigerant needs to pass through the impeller and the liquid equalization component before entering the liquid distribution chamber from the turbulence chamber. The impeller and liquid equalization component increase the turbulence and liquid distribution process of the refrigerant, realizing two-stage turbulence and liquid distribution of the refrigerant. This makes the gas-liquid two-phase distribution of the refrigerant more uniform, resulting in more uniform liquid distribution and solving the problem of uneven liquid distribution in related technologies.

[0026] Furthermore, the air conditioner provided by the present invention also possesses the various advantages described above due to the presence of the rotary distributor as described above. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0036] The following is combined Figures 1 to 6 The rotary separator of the present invention is described.

[0037] like Figures 1 to 6 As shown, the rotary distributor provided in this embodiment of the invention includes a distributor body, an impeller 1, and a liquid equalization component 2.

[0038] Specifically, the inlet end of the main body of the distributor is used to supply the refrigerant to be distributed.

[0039] The main body of the distributor is equipped with a turbulence chamber 3 and a liquid distribution chamber. The turbulence chamber 3 is located on the side of the liquid distribution chamber near the inlet end of the main body of the distributor. The end of the liquid distribution chamber near the turbulence chamber 3 is connected to the turbulence chamber 3. After the refrigerant enters the main body of the distributor, it first passes through the turbulence chamber 3 and then enters the liquid distribution chamber for liquid distribution.

[0040] Impeller 1 and liquid equalization component 2 are fixed relative to each other, and both impeller 1 and liquid equalization component 2 are rotatably arranged in turbulence chamber 3. Impeller 1 and liquid equalization component 2 can rotate synchronously relative to the liquid distributor body to stir and agitate the refrigerant and provide uniform distribution of the gas and liquid phases of the refrigerant.

[0041] The liquid equalization element 2 is located on the side of the impeller 1 near the liquid distribution chamber, and the liquid equalization element 2 has a turbulence-inducing part. Along the circumference of the liquid distributor body, the blades of the impeller 1 and the turbulence-inducing part are staggered, and there is a gap between the blades of the impeller 1 and the turbulence-inducing part for the flow of refrigerant.

[0042] When the refrigerant enters the turbulence chamber 3, it impacts the impeller 1, generating torque on the blades of the impeller 1, causing the impeller 1 to rotate relative to the main body of the distributor. The liquid equalization element 2 rotates synchronously with the impeller 1. The refrigerant acting on the impeller 1 is disturbed by the impeller 1 and can flow through the gap between the impeller 1 and the turbulence part of the liquid equalization element 2 to the space between adjacent turbulence parts of the liquid equalization element 2.

[0043] Reference Figure 1 The space between two adjacent blades of impeller 1 is simultaneously connected to the spaces on both sides of a turbulence section. The refrigerant between two adjacent blades of impeller 1 can be diverted to the spaces on both sides of the turbulence section after passing through impeller 1, thus completing one liquid separation.

[0044] The refrigerant located between adjacent turbulence sections of the liquid equalization component 2 is disturbed by the liquid equalization component 2 and can flow to the liquid distribution chamber for secondary liquid distribution.

[0045] The main body of the distributor is equipped with connection ports 4, which are used for the refrigerant to flow out of the dispensing chamber. Each connection port 4 can be connected to a flow path of the heat exchanger to ensure that the refrigerant enters the heat exchanger evenly.

[0046] With this configuration, the refrigerant entering the main body of the distributor needs to pass through the impeller 1 and the liquid equalization component 2 before entering the distribution chamber from the turbulence chamber 3. The impeller 1 and the liquid equalization component 2 increase the disturbance process and the distribution process of the refrigerant, realizing two-stage disturbance and distribution of the refrigerant, avoiding gas-liquid separation, making the gas-liquid two-phase distribution of the refrigerant more uniform, and thus making the distribution more uniform. This solves the problem of uneven distribution in the distributors of related technologies.

[0047] Furthermore, the resistance of different chambers within the liquid distribution chamber varies, resulting in different flow rates and forces acting on the liquid equalization component 2. The relatively fixed liquid equalization component 2 and impeller 1 rotate and adjust their positions in conjunction with the impact of the refrigerant on the impeller 1 and the forces acting on the liquid equalization component 2 at different chamber locations. This reduces the area of ​​the turbulent portion of the liquid equalization component 2 corresponding to the chamber with higher resistance, while increasing the area of ​​the turbulent portion of the liquid equalization component 2 corresponding to the chamber with lower resistance, thus achieving a balance and equalizing the pressure loss of different chambers within the liquid distribution chamber.

[0048] The impeller 1 described above can be configured as a turbine, but is not limited to that described above.

[0049] In this embodiment, the liquid distribution chamber has at least two sub-chambers, each sub-chamber is distributed circumferentially along the main body of the liquid distributor, and each sub-chamber is connected to the turbulence chamber 3. The refrigerant is diverted to each sub-chamber in the liquid distribution chamber.

[0050] When the main body of the distributor is arranged vertically, the inlets of each sub-chamber are equivalent to those distributed horizontally. The refrigerant at the outlet of the turbulence chamber 3 is evenly distributed at various positions in the horizontal direction, resulting in a high consistency in the gas-liquid content of the refrigerant at the inlets of each sub-chamber. This improves the consistency of the gas-liquid content of the refrigerant entering each sub-chamber, thereby achieving uniform refrigerant distribution and improving the uniformity of liquid distribution in the rotary distributor.

[0051] In this embodiment, the liquid separation chamber includes an inner cavity and an outer cavity.

[0052] Both ends of the inner cavity are closed. The inner cavity includes at least two second sub-cavities 5, which are distributed circumferentially along the inner cavity.

[0053] The outer cavity includes at least two first sub-chambers 6. Each first sub-chamber 6 is located outside the inner cavity near the end of the turbulence cavity 3, and the first sub-chambers 6 are spaced apart circumferentially along the inner cavity. Each first sub-chamber 6 is open on the side near the turbulence cavity 3 so that each first sub-chamber 6 is connected to the turbulence cavity 3.

[0054] After being disturbed and diverted by the impeller 1 and the liquid equalization component 2, the refrigerant in the turbulence chamber 3 is immediately diverted to the first sub-chamber 6 of the liquid distribution chamber, thus avoiding the gas-liquid separation process of the refrigerant at the outlet of the turbulence chamber 3 due to gravity.

[0055] The first sub-chamber 6 and the second sub-chamber 5 are connected in a one-to-one correspondence to form the aforementioned sub-chambers. The refrigerant in the turbulence chamber 3, after passing through the impeller 1 and the liquid equalization component 2, first enters the first sub-chamber 6 and then enters the second sub-chamber 5.

[0056] Specifically, a first connecting hole 8 can be provided on the side wall of each first sub-chamber 6 facing the second sub-chamber 5, that is, on the side wall of each second sub-chamber 5 facing the first sub-chamber 6, so that the first sub-chamber 6 and the second sub-chamber 5 are connected. During the process of the refrigerant flowing from the first sub-chamber 6 to the second sub-chamber 5 through the first connecting hole 8, there is also a disturbance to the refrigerant, which can promote the uniform distribution of the gas and liquid phases of the refrigerant.

[0057] In a further embodiment, the outer cavity further includes an annular flow channel 7, which extends circumferentially along the inner cavity to surround the outside of the inner cavity, and the annular flow channel 7 is located on the side of the first sub-cavity 6 away from the turbulence cavity 3. At least two annular flow channels 7 are provided, each annular flow channel 7 is distributed along the axial direction of the inner cavity, and the annular flow channels 7 are connected to the second sub-cavities 5 in a one-to-one correspondence.

[0058] A second connecting hole 9 can be provided on the side wall of each second sub-chamber 5 facing the annular flow channel 7, that is, on the side wall of each annular flow channel 7 facing the second sub-chamber 5, so that the second sub-chamber 5 is connected to the annular flow channel 7.

[0059] When the main body of the distributor is arranged vertically, each annular flow channel 7 is arranged horizontally. The refrigerant flows from the second sub-chamber 5 to the annular flow channel 7 through the second connecting hole 9, and the refrigerant flows horizontally within the annular flow channel 7. During the process of the refrigerant passing through the second connecting hole 9, there is also a disturbance to the refrigerant, which can promote a uniform distribution of the gas and liquid phases of the refrigerant.

[0060] The connection port 4 is located on the side wall of the annular flow channel 7 away from the second sub-chamber 5, and the refrigerant in the annular flow channel 7 can flow out through the connection port 4.

[0061] In this embodiment, the inlet end of the distributor body is closed, and the connection port 4 is located on the side wall of the distributor body. Specifically, the connection port 4 can be located on the side wall of the annular flow channel 7 away from the second sub-chamber 5. At least two connection ports 4 are provided, each corresponding to one sub-chamber. Each connection port 4 is used to connect to the corresponding inlet of each flow path of the heat exchanger.

[0062] The refrigerant in the annular flow channel 7 flows out through the connection port 4 on the main body of the distributor and enters each flow path of the heat exchanger. When the main body of the distributor is set vertically, the connection port 4 on the side wall of the main body of the distributor faces the horizontal direction, and the refrigerant in the annular flow channel 7 flows out horizontally.

[0063] The annular flow channel 7 allows the refrigerant to flow and exit horizontally, reducing gas-liquid separation within the channel. Even if gas-liquid separation does occur, the separated gas rises vertically rather than converging at specific cross-sections of the channel (the cross-section of the annular flow channel 7 refers to the plane perpendicular to the refrigerant's flow velocity). This ensures high consistency in the gas-liquid content at different cross-sections of the annular flow channel 7, resulting in consistent gas-liquid content in the refrigerant exiting from the connection port 4 at different times. This allows the refrigerant to enter the heat exchanger uniformly, improving its heat exchange efficiency and reducing temperature fluctuations.

[0064] In this embodiment of the invention, the various connection ports 4 are spaced apart along the axial direction of the inner cavity, that is, the various connection ports 4 are located on the same straight line.

[0065] In the prior art, the inlets of each flow path of the heat exchanger are also distributed in a straight line, so that each connection port 4 is located on the same straight line. This allows each connection port 4 of the rotary distributor to be connected to each flow path inlet of the heat exchanger in a one-to-one correspondence. This avoids the need to install connecting pipes between the rotary distributor and the heat exchanger, allowing the refrigerant diverted by the rotary distributor to directly enter the heat exchanger.

[0066] It should be noted that each of the second connecting holes 9 is distributed along a spiral line on the inner cavity to ensure that each of the second connecting holes 9 is connected to each of the second sub-cavities 5 distributed circumferentially along the inner cavity, and to ensure that each of the second connecting holes 9 is connected to each of the annular flow channels 7 distributed along the axial direction of the inner cavity.

[0067] In this embodiment of the invention, the cross-section of the outer cavity is annular. Each first sub-cavity 6 has a first sidewall and a second sidewall, which are distributed circumferentially along the outer cavity. In each first sub-cavity 6, the included angle between the first sidewall and the second sidewall corresponding to any two sides is equal.

[0068] The cross-section of the inner cavity is circular, and each second sub-cavity 5 has a third sidewall and a fourth sidewall, which are distributed circumferentially along the inner cavity. In each second sub-cavity 5, the included angle between the third and fourth sidewalls corresponding to any two is equal.

[0069] With this configuration, the cross-sectional shape and size of each first sub-chamber 6 are identical, as are the cross-sectional shape and size of each second sub-chamber 5. At any given time, the volume of refrigerant entering each of the first and second sub-chambers 6 is consistent. This consistent volume of refrigerant entering each flow path of the heat exchanger at any given time helps improve the consistency of heat exchange efficiency across the heat exchanger and provides uniform temperature across the heat exchanger surface.

[0070] In this embodiment of the invention, the flow-dispersing portion has a first edge and a second edge, which are distributed circumferentially along the outer cavity. The angle between the first edge and the second edge of the flow-dispersing portion is equal to the angle between the first sidewall and the second sidewall of the first sub-cavity 6.

[0071] Specifically, eight first sub-chambers 6 and eight second sub-chambers 5 can be provided. The impeller 1 has four blades, and the liquid equalization component 2 has four turbulence sections. Each pair of adjacent turbulence sections in the liquid equalization component 2 corresponds to one blade of the impeller 1. The cross-sectional shape of a single turbulence section of the liquid equalization component 2 matches that of a single first sub-chamber 6. The liquid equalization component 2 can intermittently drive the refrigerant in the turbulence chamber 3 into the first sub-chamber 6. Moreover, it is beneficial to better equalize the pressure loss of different chambers in the liquid equalization chamber.

[0072] In this embodiment, the connection port 4 can be configured as a circular hole to accommodate connection with a finned tube heat exchanger. Alternatively, the connection port 4 can be configured as a strip-shaped hole extending circumferentially along the body of the distributor to accommodate connection with a microchannel heat exchanger.

[0073] In a specific embodiment of the present invention, the main body of the liquid dispenser includes a first tube 10, a second tube 11, a first partition plate 12, a second partition plate 13, and a third partition plate 14.

[0074] The cross-sectional shape of the first tube 10 and the second tube 11 is circular. Specifically, a circular metal tube can be selected as the first tube 10 and the second tube 11.

[0075] The first partition plate 12 and the third partition plate 14 are both rectangular, while the second partition plate 13 is circular.

[0076] Both ends of the first tube 10 are closed. The first partition plate 12 is disposed inside the first tube 10. There are at least two first partition plates 12. The first partition plate 12 extends from the central axis of the first tube 10 to the inner wall of the first tube 10. Each first partition plate 12 is distributed at intervals along the circumference of the first tube 10. That is, each first partition plate 12 is radially distributed with the central axis of the first tube 10 as the center.

[0077] The first partition plate 12 is sealed to the first tube 10. Each of the first partition plates 12 is sealed together near the central axis of the first tube 10, so that two adjacent first partition plates 12 and the first tube 10 enclose each other to form a second sub-chamber 5.

[0078] The second tube 11 is fitted over the first tube 10, with its second end flush with the second end of the first tube 10, both in a closed state. The first end of the second tube 11 is open, and the axial length of the first tube 10 is less than the axial length of the second tube 11. The second end of the first tube 10 is located inside the second tube 11, and the space between the second end of the second tube 11 and the first end face of the first tube 10 forms a turbulence cavity 3. The impeller 1 and the liquid equalization component 2 are located at the first end face of the first tube 10.

[0079] Multiple second partition plates 13 are provided, and the second partition plates 13 are disposed between the first tube 10 and the second tube 11, with each second partition plate 13 spaced apart along the axial direction of the first tube 10. The inner edge of the second partition plate 13 is sealed to the first tube 10, and the outer edge of the second partition plate 13 is sealed to the second tube 11, so as to divide the space between the first tube 10 and the second tube 11 into multiple annular cavities.

[0080] Of the annular cavities, the one closest to the turbulence chamber 3 is the first annular cavity, and the rest are the second annular cavities. A third partition plate 14 is disposed within the first annular cavity and is arranged radially along the second tube 11 to divide the first annular cavity into multiple spaces distributed circumferentially along the first tube 10; these spaces are the first sub-chambers 6. First connecting holes 8 are respectively provided on the first tube 10 at positions corresponding to each of the first sub-chambers 6.

[0081] The second annular cavity serves as an annular flow channel 7. Second connecting holes 9 are respectively provided on the first tube 10 at positions directly opposite each annular flow channel 7 and each first sub-chamber 6. Connection ports 4 are respectively provided on the second tube 11 at positions directly opposite each annular flow channel 7.

[0082] With this configuration, the main body of the separator is formed by processing the first tube 10, the second tube 11, the first partition plate 12, the second partition plate 13, and the third partition plate 14, resulting in a simple structure and low cost.

[0083] When using the first partition plate 12, the second partition plate 13, and the third partition plate 14 to create different spaces, it is necessary to ensure that the first partition plate 12, the second partition plate 13, and the third partition plate 14 are all sealed to their adjacent components. Sealing can be achieved through welding.

[0084] The aforementioned third partition plates 14 have the same shape and are evenly distributed along the circumference of the first tube 10. That is, the included angle between any third partition plate 14 and the third partition plates 14 located on both sides thereare equal, so that the cross-sectional shape and size of each first sub-chamber 6 are consistent.

[0085] Each of the first partition plates 12 has the same shape and is evenly distributed along the circumference of the first tube 10. That is, the included angle between any one of the first partition plates 12 and the first partition plates 12 located on both sides thereis is equal, so that the cross-sectional shape and size of each of the second sub-chambers 5 are consistent.

[0086] In a specific embodiment, eight first partition plates 12 are provided, as shown in the reference. Figure 6 Eight first partition plates 12 are spaced apart, with an included angle of 45 degrees between adjacent first partition plates 12, dividing the inner cavity of the first tube 10 into eight second sub-chambers 5 of the same shape and size. Second partition plates 13 divide the annular cavity between the second tube 11 and the first tube 10 into eight annular flow channels 7 of the same shape and size and a first annular cavity. Eight third partition plates 14 are provided, as shown in the diagram. Figure 5 Eight third partition plates 14 are spaced apart, with an included angle of 45 degrees between two adjacent third partition plates 14, dividing the first annular cavity into eight first sub-chambers 6.

[0087] The opening size of the first end of the second pipe body 11 can be reduced by designing a narrowing end according to the diameter of the main pipeline.

[0088] Each of the turbulence-dispersing parts of the liquid equalizing component 2 is fan-shaped. The diameter of the liquid equalizing component 2 is the same as the diameter of the second tube 11, and the diameter of the impeller 1 is the same as the diameter of the constriction of the second tube 11.

[0089] On the other hand, embodiments of the present invention also provide an air conditioner, including the rotary distributor provided in any of the above embodiments. The rotary distributor provided in any of the above embodiments has the advantage of uniform liquid distribution; therefore, the air conditioner in this embodiment has the advantages of high energy efficiency, long lifespan, low noise, and high reliability. The derivation process of the beneficial effects of the air conditioner in the embodiments of the present invention is largely similar to the derivation process of the beneficial effects of the rotary distributor described above, and therefore will not be repeated here.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
