Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to a liquid dispenser 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] In related technologies, liquid distributors typically have a main pipe arranged vertically, with multiple branch outlets distributed along the axis of the main pipe. Because the refrigerant has two phases (gas and liquid), the refrigerant in the main pipe separates into these two phases under gravity. The upper portion of the refrigerant has a higher gaseous component, while the lower portion has a higher liquid component. This results in inconsistent states and proportions of the refrigerant flowing from each branch outlet, leading to uneven liquid distribution and poor heat exchange efficiency in the heat exchanger.

[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. Utility Model Content

[0005] This utility model provides a liquid dispenser and an air conditioner to solve the defect of uneven liquid distribution in related technologies.

[0006] This utility model provides a liquid dispenser, including a liquid dispenser tube, wherein the first end of the liquid dispenser tube is open and adapted to be connected to a main pipeline, and the second end of the liquid dispenser tube is closed.

[0007] The dispensing tube has at least two sub-chambers inside, each of the sub-chambers is distributed along the circumference of the dispensing tube, and each of the sub-chambers is connected to the first end of the dispensing tube through an open end.

[0008] The side wall of the liquid distribution pipe is provided with a refrigerant outlet, each of the refrigerant outlets is connected to one of the sub-chambers, and each of the refrigerant outlets is adapted to allow the refrigerant in each of the sub-chambers to flow to each flow path of the heat exchanger.

[0009] With this configuration, the refrigerant in the main pipeline is immediately diverted to each sub-chamber upon entering the first end of the distributor, avoiding gas-liquid separation due to gravity at the first end of the distributor. When the distributor is vertically positioned, the inlets of each sub-chamber are distributed horizontally. When the refrigerant flows to the open position at the first end of the distributor, the refrigerant 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 uniformity of the gas-liquid content of the refrigerant entering each sub-chamber, thus achieving uniform refrigerant diversion and enhancing the distributor's liquid distribution uniformity.

[0010] According to the present invention, a liquid distributor further includes a flow guide tube, which is sleeved on the outside of the liquid distributor tube. At least two annular flow channels are formed between the flow guide tube and the liquid distributor tube. Each of the annular flow channels is distributed along the axial direction of the liquid distributor tube, and each refrigerant outlet is connected to one of the annular flow channels.

[0011] The side wall of the guide pipe is provided with at least two connection ports, each of which is connected to one of the annular flow channels. The connection ports are adapted to be connected to the inlets of each flow path of the heat exchanger.

[0012] Thus, the design of the guide pipe allows the refrigerant to flow horizontally within and out of the annular channel, 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 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 channel, resulting in consistent gas-liquid content in the refrigerant flowing out from the connection point at different times. This allows the refrigerant to enter the heat exchanger uniformly, improving its heat exchange efficiency and reducing temperature fluctuations.

[0013] According to the present invention, a liquid separator is provided in which each of the connection ports is spaced apart along the axial direction of the guide tube.

[0014] 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 each connection port is located on the same straight line. This allows each connection port of the distributor to be connected to each flow path inlet of the heat exchanger in a one-to-one correspondence, avoiding the need to install connecting pipes between the distributor and the heat exchanger. The refrigerant diverted by the distributor directly enters the heat exchanger.

[0015] According to the present invention, a liquid separator is provided, wherein the liquid separator tube includes a first tube body and at least two first partition plates. The first partition plates are disposed inside the first tube body and extend from the central axis of the first tube body to the inner sidewall of the first tube body. Each of the first partition plates is distributed at intervals along the circumference of the first tube body. The first partition plates are sealed to the first tube body. Two adjacent first partition plates and the first tube body enclose the sub-chamber.

[0016] The refrigerant outlet is located on the first pipe body at a position between two adjacent first partition plates.

[0017] With this configuration, the separator consists of a first tube body and a first partition plate, and each sub-chamber is separated by the first partition plate. The structure is simple and the cost is low.

[0018] According to the present invention, each of the first partition plates has the same shape and is evenly distributed along the circumference of the first tube.

[0019] With this configuration, the cross-sectional shape and size of each sub-chamber are consistent. At the same time, the volume of refrigerant entering each sub-chamber of the distributor is consistent, and the volume of refrigerant entering each flow path of the heat exchanger is consistent at the same time. This helps to improve the consistency of heat exchange efficiency at various locations of the heat exchanger and provides temperature uniformity on the surface of the heat exchanger.

[0020] According to the present invention, a liquid separator is provided, wherein the guide tube includes a second tube body and a plurality of second partition plates. The second tube body is sleeved on the outside of the liquid separator, and an annular cavity is formed between the second tube body and the liquid separator. The second partition plates are disposed between the second tube body and the liquid separator, and each of the second partition plates is spaced apart along the axial direction of the liquid separator to divide the annular cavity into at least two annular flow channels.

[0021] The connection port is provided on the second tube at a position between two adjacent second partition plates.

[0022] With this configuration, the guide tube consists of a second tube body and a second partition plate, and each annular flow channel is separated by the second partition plate. The structure is simple and the cost is low.

[0023] According to the present invention, a liquid separator further includes an impeller, which is disposed inside the first end of the liquid separator tube. The impeller is rotatably connected to the liquid separator tube, and the rotation axis of the impeller relative to the liquid separator tube is parallel to the axis of the liquid separator tube.

[0024] With this configuration, when the refrigerant enters the first end of the distributor, it impacts the impeller, generating torque on the impeller blades and causing the impeller to rotate relative to the distributor. This rotation of the impeller relative to the distributor stirs and agitates the refrigerant at the first end of the distributor, ensuring uniform mixing of the gas and liquid phases and preventing gas-liquid separation.

[0025] According to the present invention, the liquid separator has a circular orifice or a strip-shaped orifice that extends circumferentially along the liquid separator tube.

[0026] 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.

[0027] According to the present invention, the first tube has a circular cross-section.

[0028] This setup is simple in structure, and the position of each first partition plate can be determined simply by controlling the included angle between each first partition plate, thereby ensuring the consistency of the cross-sectional shape and size of each sub-chamber. The structure and design process are simple.

[0029] This utility model also provides an air conditioner, including the liquid dispenser as described above.

[0030] The distributor provided by this utility model includes a dispensing pipe with an open first end for connecting to a main pipeline. Refrigerant in the main pipeline can enter the dispensing pipe through the first end. The second end of the dispensing pipe is closed. The dispensing pipe has at least two sub-chambers, each connected to the open first end of the pipe. Upon entering the first end of the dispensing pipe, the refrigerant is immediately distributed to each sub-chamber. The sub-chambers are distributed circumferentially along the dispensing pipe. When the dispensing pipe is vertical, the inlets of each sub-chamber are equivalent to those distributed horizontally. The refrigerant at the open first end of the dispensing pipe is evenly distributed horizontally, ensuring uniform distribution to each sub-chamber. Refrigerant outlets are provided on the side wall of the dispensing pipe, each outlet corresponding to a sub-chamber. Each refrigerant outlet allows the refrigerant in each sub-chamber to flow to different flow paths in the heat exchanger. With this configuration, the refrigerant in the main pipeline is immediately diverted to each sub-chamber upon entering the first end of the distributor, avoiding gas-liquid separation due to gravity at the first end of the distributor. When the distributor is vertically positioned, the inlets of each sub-chamber are distributed horizontally. When the refrigerant flows to the open position at the first end of the distributor, the refrigerant 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 uniformity of the gas-liquid content of the refrigerant entering each sub-chamber, thus achieving uniform refrigerant diversion and improving the distributor's liquid distribution uniformity. This solves the problem of uneven liquid distribution in related technologies.

[0031] Furthermore, the air conditioner provided by this utility model has the liquid distributor as described above, and therefore also has the various advantages described above. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] The following is combined Figures 1 to 6 This invention describes the liquid separator.

[0043] like Figures 1 to 6 As shown, the liquid dispenser provided in this embodiment of the present invention includes a liquid dispensing tube 1.

[0044] Specifically, the first end of the distributor 1 is open and is used to connect to the main pipeline. The refrigerant in the main pipeline can enter the distributor 1 through the first end of the distributor 1.

[0045] The second end of the distributor 1 is closed, and the distributor 1 has at least two sub-chambers 2 inside. Each sub-chamber 2 is connected to the first end of the distributor 1 at the open end. When the refrigerant enters the first end of the distributor 1, it is diverted to each sub-chamber 2. There is no gas-liquid separation problem at the first end of the distributor 1.

[0046] Each sub-chamber 2 is distributed circumferentially along the distribution pipe 1. When the distribution pipe 1 is set vertically, the inlets of each sub-chamber 2 are equivalent to being distributed horizontally. The refrigerant at the first open end of the distribution pipe 1 is evenly distributed at all positions in the horizontal direction, thereby ensuring that the refrigerant is evenly distributed into each sub-chamber 2.

[0047] The side wall of the liquid separator 1 is provided with a refrigerant outlet 3. Each refrigerant outlet 3 is connected to a sub-chamber 2. Each refrigerant outlet 3 supplies the refrigerant in each sub-chamber 2 to flow to each flow path of the heat exchanger.

[0048] With this configuration, the refrigerant in the main pipeline is immediately diverted to each sub-chamber 2 upon entering the first end of the distributor 1, avoiding gas-liquid separation due to gravity at the first end of the distributor 1. When the distributor is set vertically, the inlets of each sub-chamber 2 are distributed horizontally. When the refrigerant flows to the open position at the first end of the distributor 1, the refrigerant is evenly distributed along the horizontal direction, resulting in a high consistency in the gas-liquid content of the refrigerant at the inlets of each sub-chamber 2. This improves the consistency of the gas-liquid content of the refrigerant entering each sub-chamber 2, thereby achieving uniform refrigerant diversion, improving the liquid distribution uniformity of the distributor, and solving the problem of uneven liquid distribution in related technologies.

[0049] In this embodiment of the invention, the distributor further includes a guide tube, which is sleeved outside the distributor tube 1. At least two annular flow channels 4 are formed between the guide tube and the distributor tube 1, and each annular flow channel 4 is distributed along the axial direction of the distributor tube 1. Each refrigerant outlet 3 is connected to one annular flow channel 4. When the distributor tube 1 is arranged vertically, each annular flow channel 4 is arranged horizontally. The refrigerant enters the annular flow channel 4 of the guide tube through the refrigerant outlet 3, and flows horizontally within the annular flow channel 4.

[0050] At least two connection ports 5 are provided on the side wall of the guide tube. Each connection port 5 is connected to an annular flow channel 4. The connection port 5 is used to connect to the inlet of each flow path of the heat exchanger.

[0051] The refrigerant in the annular flow channel 4 flows out through the connection port 5 on the side wall of the guide pipe and enters each flow path of the heat exchanger. When the liquid separator 1 is set vertically, the guide pipe is also set vertically, and the connection port 5 on the side wall of the guide pipe faces horizontally, so the refrigerant in the annular flow channel 4 flows out horizontally.

[0052] The design of the guide pipe allows the refrigerant to flow horizontally within and out of the annular channel 4, 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 annular channel 4 (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 channel 4, resulting in consistent gas-liquid content in the refrigerant exiting the connection port 5 at different times. This allows the refrigerant to enter the heat exchanger uniformly, improving its heat exchange efficiency and reducing temperature fluctuations.

[0053] In this embodiment, the various connection ports 5 are spaced apart along the axial direction of the guide tube, that is, the various connection ports 5 are located on the same straight line.

[0054] 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 5 is located on the same straight line. This allows each connection port 5 of the 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 distributor and the heat exchanger, allowing the refrigerant distributed by the distributor to directly enter the heat exchanger.

[0055] It should be noted that each refrigerant outlet 3 is distributed along a spiral line on the first pipe body 6 to ensure that each refrigerant outlet 3 is connected to each sub-chamber 2 distributed circumferentially along the distribution pipe 1, and to ensure that each refrigerant outlet 3 is connected to each annular flow channel 4 distributed along the axial direction of the distribution pipe 1.

[0056] In this embodiment, the liquid separator 1 includes a first tube body 6 and a first partition plate 7, with the first partition plate 7 disposed inside the first tube body 6.

[0057] At least two first partition plates 7 are provided. The first partition plates 7 extend from the central axis of the first tube 6 to the inner wall of the first tube 6. Each first partition plate 7 is distributed at intervals along the circumference of the first tube 6. That is, each first partition plate 7 is distributed radially with the central axis of the first tube 6 as the center.

[0058] The first partition plate 7 is sealed to the first tube body 6. Each of the first partition plates 7 is sealed together near the central axis of the first tube body 6, so that two adjacent first partition plates 7 and the first tube body 6 enclose each other to form a sub-chamber 2.

[0059] A refrigerant outlet 3 is provided on the first pipe body 6 at a position between two adjacent first partition plates 7.

[0060] With this configuration, each sub-chamber 2 is separated by the first partition plate 7, resulting in a simple structure and low cost.

[0061] The sealing connection between the first partition plate 7 and the first tube body 6, as well as the sealing connection between adjacent first partition plates 7, can both be achieved through welding.

[0062] In this embodiment, all the first partition plates 7 have the same shape and are evenly distributed along the circumference of the first tube 6. That is, the included angle between any one first partition plate 7 and the first partition plates 7 on its two sides is equal, and the cross-sectional shape and size of each sub-chamber 2 are consistent. At the same time, the volume of refrigerant entering each sub-chamber 2 of the liquid distribution pipe 1 is consistent, and the volume of refrigerant entering each flow path of the heat exchanger at the same time is consistent. This is beneficial to improving the consistency of heat exchange efficiency at various locations of the heat exchanger and providing temperature uniformity on the surface of the heat exchanger.

[0063] In a specific embodiment, the cross-section of the first tube 6 can be set to a circle, which is simple in structure. The position of each first partition plate 7 can be determined by controlling the included angle between each first partition plate 7, thereby ensuring the consistency of the cross-sectional shape and size of each sub-chamber 2. The structure and design process are simple.

[0064] In this embodiment, the guide tube includes a second tube body 8 and a plurality of second partition plates 9. The second tube body 8 is sleeved on the outside of the liquid distribution tube 1, and an annular cavity is formed between the second tube body 8 and the liquid distribution tube 1.

[0065] The second partition plate 9 is disposed between the second tube body 8 and the liquid distribution pipe 1. The second partition plates 9 are spaced apart along the axial direction of the liquid distribution pipe 1 to divide the annular cavity into at least two annular flow channels 4. A connection port 5 is provided on the second tube body 8 at a position between two adjacent second partition plates 9.

[0066] With this configuration, each annular flow channel 4 is separated by the second partition plate 9, resulting in a simple structure and low cost.

[0067] In this embodiment, the cross-section of the second tube 8 is also set to be circular, and both the first tube 6 and the second tube 8 can be directly selected as circular metal tubes.

[0068] In a specific embodiment, the first partition plate 7 is a flat plate, and the liquid distribution tube 1 has eight first partition plates 7, as shown in the reference. Figure 1 and Figure 6 Eight first partition plates 7 are spaced apart, with an included angle of 45 degrees between adjacent first partition plates 7, dividing the inner cavity of the first tube 6 into eight sub-chambers 2 of the same shape and size. The second partition plates 9 are planar and annular; the guide tube has nine second partition plates 9, as shown in the reference section. Figure 6Nine second partition plates 9 are distributed at intervals, with the distance between two adjacent second partition plates 9 being the same, dividing the annular cavity between the second tube body 8 and the first tube body 6 into eight annular flow channels 4 of the same shape and size.

[0069] In this embodiment of the invention, the distributor further includes an impeller 10, which is disposed inside the first end of the dispensing pipe 1. The impeller 10 is rotatably connected to the dispensing pipe 1, and the axis of rotation of the impeller 10 relative to the dispensing pipe 1 is parallel to the axis of the dispensing pipe 1. When the refrigerant enters the first end of the dispensing pipe 1, it impacts the impeller 10, generating torque on the blades of the impeller 10, causing the impeller 10 to rotate relative to the dispensing pipe 1. During the rotation of the impeller 10 relative to the dispensing pipe 1, the refrigerant at the first end of the dispensing pipe 1 is stirred and disturbed, ensuring uniform mixing of the gas and liquid phases of the refrigerant, preventing gas-liquid separation, and allowing the refrigerant to uniformly enter each sub-chamber 2.

[0070] The impeller 10 described above can be configured as a turbine, but is not limited to that described above.

[0071] In this embodiment of the invention, the connection port 5 can be configured as a circular hole to accommodate connection with a finned tube heat exchanger. Alternatively, the connection port 5 can be configured as a strip-shaped hole extending circumferentially along the distribution pipe 1 to accommodate connection with a microchannel heat exchanger.

[0072] On the other hand, this utility model embodiment also provides an air conditioner, including the liquid distributor provided in any of the above embodiments. The liquid 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 this utility model embodiment is largely similar to the derivation process of the beneficial effects of the liquid distributor described above, and therefore will not be repeated here.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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. Such 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 this utility model.
