Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and in particular to a distributor, a heat exchanger assembly, and an air conditioner having the same. Background Technology

[0002] In the existing technology, the distributor uses a mixed flow method to distribute the flow at the inlet section. However, due to the different back pressures of each branch pipe, it is difficult to achieve uniform flow distribution in different branch pipes, which affects the working efficiency of the heat exchanger, causes uneven air outlet temperature of the air conditioner, and reduces the user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a distributor that can evenly distribute the liquid flow in multiple branch pipes, improve the heat exchange capacity of the heat exchanger assembly, and enhance the user experience.

[0004] The present invention also proposes a heat exchanger assembly comprising the distributor described above.

[0005] The present invention also proposes an air conditioner, which includes the heat exchanger assembly described above.

[0006] A distributor according to an embodiment of the present invention includes: a distributor body having a distribution cavity; an inlet / outlet pipe and a branch pipe, the inlet / outlet pipe and the branch pipe being respectively connected to opposite ends of the distributor body, the branch pipes being a plurality of spaced-apart pipes; and a flow equalization assembly including a flow equalization element and a gas transmission element, the flow equalization element having a flow equalization cavity, the gas transmission element being disposed within the flow equalization cavity, the flow equalization assembly being connected to the plurality of branch pipes and the flow equalization cavity being in communication with the plurality of branch pipes, the flow equalization assembly being configured to allow gas to flow only between the plurality of branch pipes.

[0007] According to the present invention, the distributor connects multiple branch pipes through a flow equalization component and connects multiple branch pipes through a flow equalization cavity. The flow equalization component only allows gas to flow between multiple branch pipes, and allows gas to flow from one branch pipe to another through the flow equalization cavity, thereby keeping the pressure in different branch pipes consistent. As a result, the liquid flow rate in each branch pipe eventually tends to be uniformly distributed, which can improve the heat exchange capacity of the heat exchanger assembly, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0008] In addition, the dispenser according to the present invention may also have the following additional technical features:

[0009] In some embodiments, the flow equalization device includes a plurality of interconnecting pipes, one end of which is connected to and communicates with each other, and the other end of which is connected to and communicates with a plurality of branch pipes respectively. The space inside the plurality of interconnecting pipes forms the flow equalization cavity. The gas transmission device is a breathable membrane, and each interconnecting pipe is provided with the breathable membrane.

[0010] In some embodiments, the length of the connecting pipe is L1, and the distance between the breathable membrane inside the connecting pipe and the end of the connecting pipe closest to the corresponding branch pipe is L2, satisfying: L2 / L1≥0.3.

[0011] In some embodiments, the breathable membrane within each of the connecting pipes is located at the same position within the respective connecting pipe.

[0012] In some embodiments, the plurality of connecting pipes have the same length; and / or, the plurality of connecting pipes have the same diameter.

[0013] In some embodiments, at least one of the communicating pipes is provided with multiple layers of the breathable membrane.

[0014] In some embodiments, the breathable membrane is a PTFE film.

[0015] In some embodiments, the total length of the branch pipe is L3, and the distance between the position where the branch pipe communicates with the flow equalization cavity and the end of the branch pipe closer to the distributor body is L4, satisfying: 0.3≤L4 / L3≤0.8.

[0016] In some embodiments, the location on each of the branch pipes that communicates with the flow equalization cavity is the same.

[0017] In some embodiments, the plurality of branch pipes have the same length; and / or, the plurality of branch pipes have the same diameter.

[0018] In some embodiments, the plurality of branch pipes are evenly spaced along the circumferential direction of the distributor body, and the flow equalization component is disposed within the central space defined by the plurality of branch pipes.

[0019] The present invention also provides a heat exchanger assembly having the above embodiments.

[0020] According to the embodiments of the present invention, the heat exchanger assembly connects multiple branch pipes through a flow equalization component, and the flow equalization cavity connects the multiple branch pipes. The flow equalization component only allows gas to flow between the multiple branch pipes, and allows gas to flow from one branch pipe to another through the flow equalization cavity, thereby keeping the pressure in different branch pipes consistent. As a result, the liquid flow rate in each branch pipe eventually tends to be uniformly distributed, which can improve the heat exchange capacity of the heat exchanger assembly, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0021] The present invention also provides an air conditioner having the above-described embodiments.

[0022] According to an embodiment of the present invention, an air conditioner connects multiple branch pipes via a flow equalization assembly, and the flow equalization cavity connects the multiple branch pipes. The flow equalization assembly only allows gas to flow between the multiple branch pipes, allowing gas to flow from one branch pipe to another through the flow equalization cavity. This ensures that the pressure in different branch pipes remains consistent, thereby making the liquid flow rate in each branch pipe tend to be uniformly distributed. This can improve the heat exchange capacity of the heat exchanger assembly, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0043] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] The distributor 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, the distributor 100 according to an embodiment of the present invention includes a distributor body 1, an inlet / outlet liquid pipe 2, a branch pipe 3, and a flow equalization component 4.

[0049] Specifically, see the attached document. Figure 1 As shown, the distributor body 1 is cylindrical and has a distribution cavity through which refrigerant can pass. In a specific example, such as... Figure 1 As shown, the dispenser body 1 is cylindrical. Of course, the present invention is not limited to this, and the dispenser body 1 can also be other shapes or cylindrical bodies with varying diameters.

[0050] Further, see Appendix Figure 1 As shown, the inlet / outlet pipe 2 and the branch pipe 3 are respectively connected to opposite ends of the distributor body 1, and both the inlet / outlet pipe 2 and the branch pipe 3 are connected to the distribution chamber. The diameters of the inlet / outlet pipe 2 and the branch pipe 3 are smaller than the diameter of the distribution chamber. The refrigerant enters the distribution chamber of the distributor body 1 through the inlet / outlet pipe 2. Due to the sudden increase in pipe diameter, the gas-liquid two-phase mixing can be more uniform. Further, refer to the attached... Figure 1 As shown, the branch pipes 3 are spaced apart, allowing refrigerant in the distribution chamber to flow out through multiple channels. This increases the pathways for refrigerant to reach the heat exchanger body 5, achieving refrigerant diversion, improving the heat exchange efficiency of the heat exchanger assembly 200, and enhancing the user experience. For example, the branch pipes 3 can be two, three, four, five, or six spaced apart. In a specific embodiment, refer to the attached diagram. Figure 1As shown, the branch pipes 3 are three spaced apart.

[0051] Furthermore, see the attached document. Figure 2 As shown, the flow equalization assembly 4 includes a flow equalization element 41 and a gas transmission element 42. The flow equalization element 41 has a flow equalization cavity 411, and the gas transmission element 42 is disposed in the flow equalization cavity 411. The flow equalization assembly 4 is connected to multiple branch pipes 3, and the flow equalization cavity 411 is connected to multiple branch pipes 3. The flow equalization assembly 4 is configured to allow gas to flow only between multiple branch pipes 3, limiting the flow of gas in the refrigerant in multiple branch pipes 3, while the flow of liquid in the refrigerant cannot flow in multiple branch pipes 3.

[0052] Understandably, refrigerant can flow from one branch pipe 3 to the flow equalization chamber 411. Since the gas transmission component 42 only allows gas to pass through, the gas in the refrigerant can flow through the gas transmission component 42 and the flow equalization chamber 411 to another branch pipe 3. Thus, the gas can flow from one branch pipe 3 to another, keeping the pressure in different branch pipes 3 consistent. Consequently, the liquid flow rate in each branch pipe 3 eventually tends to be uniformly distributed, which can improve the heat exchange capacity of the heat exchanger assembly 200, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0053] According to the present invention, the distributor 100 connects multiple branch pipes 3 through a flow equalization component 4 and a flow equalization cavity 411 connects the multiple branch pipes 3. The flow equalization component 4 only allows gas to flow between the multiple branch pipes 3, so that gas can flow from one branch pipe 3 to another branch pipe 3 through the flow equalization cavity 411, thereby keeping the pressure in different branch pipes 3 consistent, and thus making the liquid flow rate in each branch pipe 3 eventually tend to be uniformly distributed. This can improve the heat exchange capacity of the heat exchanger assembly 200, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0054] In some embodiments of the present invention, reference is made to the appendix. Figure 2 As shown, the flow equalization device 41 includes multiple connecting pipes 412. One end of the multiple connecting pipes 412 is connected to each other and communicates with each other. The other end of the multiple connecting pipes 412 is connected to multiple branch pipes 3 respectively and communicates with each other. The space inside the multiple connecting pipes 412 forms a flow equalization cavity 411. The gas transmission device 42 is a breathable membrane 421. Each connecting pipe 412 is provided with a breathable membrane 421, which allows only gas to pass through at the breathable membrane 421 of each connecting pipe 412, so that the liquid remains in the corresponding branch pipe 3.

[0055] It should be noted that the number of connecting pipes 412 is consistent with the number of branch pipes 3. In a specific example, refer to the appendix... Figure 2As shown, the flow equalization component 41 includes three interconnecting pipes 412. One end of the three interconnecting pipes 412 is connected to each other and communicates with each other. The other end of the three interconnecting pipes 412 is connected to three branch pipes 3 respectively and communicates with each other.

[0056] It is understandable that the gas in the first branch pipe 3 can flow through the permeable membrane 421 in the first connecting pipe 412 to the permeable membrane 421 in the second connecting pipe 412, and then flow through the permeable membrane 421 in the second connecting pipe 412 to the second branch pipe 3. The first connecting pipe 412 is connected and communicates with the first branch pipe 3, and the second connecting pipe 412 is connected and communicates with the second branch pipe 3.

[0057] Understandably, when the pressure in the first branch pipe 3 is greater than the pressure in the second branch pipe 3, the gas in the first branch pipe 3 can enter the second branch pipe 3 successively through the permeable membrane 421 in the first connecting pipe 412 and the second connecting pipe 412, thereby increasing the mass flow rate in the second branch pipe 3, which in turn increases the frictional pressure drop in the second branch pipe 3, and thus the pressure in the second branch pipe 3 gradually increases. At the same time, the pressure in the first branch pipe 3 gradually decreases until the pressure in the second branch pipe 3 is equal to the pressure in the first branch pipe 3. The first connecting pipe 412 is connected to and communicates with the first branch pipe 3, and the second connecting pipe 412 is connected to and communicates with the second branch pipe 3. Furthermore, when the pressure of one branch pipe 3 is higher than the average pressure of multiple branch pipes 3, the gas in that branch pipe 3 will flow through the permeable membrane 421 in the equalization chamber 411 to the branch pipe 3 whose pressure is lower than the average pressure of multiple branch pipes 3, until the pressure in multiple branch pipes 3 is equal.

[0058] In a further embodiment of the invention, reference is made to the appendix. Figure 3 As shown, the length of the connecting pipe 412 is L1, and the distance between the permeable membrane 421 inside the connecting pipe 412 and the end of the connecting pipe 412 near the corresponding branch pipe 3 is L2, satisfying: L2 / L1≥0.3. It should be noted that the end of the connecting pipe 412 near the corresponding branch pipe 3 is in contact with the outer wall of the corresponding branch pipe 3, thus ensuring that the distance of the end of the connecting pipe 412 near the corresponding branch pipe 3 along the thickness direction of the flow equalization component 4 (see attached diagram). Figure 1The two sides of the direction shown (a) are two arc surfaces. The plane formed by one end of the arc surface and the axis of the branch pipe 3 coincides with the plane formed by the other end of the arc surface and the axis of the branch pipe 3. At this time, the length L1 of the connecting pipe 412 is the distance from the connection point of the multiple connecting pipes 412 to the axis of the corresponding branch pipe 3, and the distance L2 between the breathable membrane 421 in the corresponding connecting pipe 412 and the end of the connecting pipe 412 near the corresponding branch pipe 3 is the distance from the breathable membrane 421 in the corresponding connecting pipe 412 to the axis of the corresponding branch pipe 3.

[0059] Understandably, see attached document. Figure 5 As shown, the heat exchange capacity changes with L2 / L1 under rated refrigeration and intermediate refrigeration conditions. When L2 / L1 < 0.3, the distance between the permeable membrane 421 and the end of the connecting pipe 412 closest to the corresponding branch pipe 3 is too close, and the gas and liquid easily carry each other without pressure effect, so the increase in heat exchange capacity is not significant. However, when L2 / L1 ≥ 0.3, there is a certain distance between the permeable membrane 421 and the end of the connecting pipe 412 closest to the corresponding branch pipe 3, the pressure effect of the flow equalization component 4 is better, the pressure in multiple branch pipes 3 is balanced, and the flow rate in different branch pipes 3 tends to be uniform, which can improve the heat exchange capacity of the heat exchanger assembly 200. It should be noted that the value of L2 / L1 must also satisfy L2 / L1 < 1 to ensure that the permeable membrane 421 is located inside the connecting pipe 412. For example, L2 / L1 can be 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 or 0.9.

[0060] In a further embodiment of the invention, reference is made to the appendix. Figure 3 As shown, the permeable membrane 421 in each connecting pipe 412 is located at the same position in the corresponding connecting pipe 412, which enables the permeable membrane 421 to start working at the same position in each connecting pipe 412 to separate the gas and liquid, so that the refrigerant in each connecting pipe 412 receives the same gas-liquid separation effect, and the pressure in the multiple branch pipes 3 can be balanced as soon as possible, thereby improving the heat exchange capacity of the heat exchanger assembly 200.

[0061] Of course, the present invention is not limited to this. The breathable membrane 421 in each connecting pipe 412 can also be located in different positions in the corresponding connecting pipe 412. No further restrictions are imposed here.

[0062] In a further embodiment of the present invention, the multiple connecting pipes 412 are of the same length, which ensures that the refrigerant in each connecting pipe 412 travels the same distance, thus promoting uniform flow in the branch pipe 3. Furthermore, the multiple connecting pipes 412 have the same diameter, which ensures that the flow quality in the multiple connecting pipes 412 is the same, further promoting uniform flow in the branch pipe 3. In a specific example, refer to the attached... Figure 2As shown, the multiple connecting pipes 412 have the same length and diameter, which facilitates the production and manufacturing of the flow equalization component 4 and can reduce the production and development cost of the distributor 100. Furthermore, the multiple connecting pipes 412 with the same length and diameter can form a stable structure, and the connecting pipes 412 support each other, which can improve the stability of the flow equalization component 4.

[0063] In some embodiments, the multiple connecting pipes 412 may have the same length but different diameters; or, the multiple connecting pipes 412 may have different lengths but the same diameter; or, the multiple connecting pipes 412 may have the same length and diameter. The length and diameter of the multiple connecting pipes 412 can be selected according to the actual needs of different distributors 100 to meet different usage requirements.

[0064] Of course, the present invention is not limited to this. The lengths and diameters of the multiple connecting pipes 412 may also be different. No further restrictions are imposed here.

[0065] In a further embodiment of the present invention, at least one connecting pipe 412 is provided with multiple layers of permeable membranes 421. This multi-layer permeable membrane 421 further enhances the effect of allowing gas to pass through while preventing liquid flow, thus preventing liquid and gas from carrying each other. It also improves the strength of the gas transmission component 42, extends the service life of the flow equalization component 4, and reduces the frequency and cost of maintenance for the distributor 100. For example, one, two, three, four, five, six, or seven layers of permeable membranes 421 can be provided within a connecting pipe 412. Preferably, three to five layers of permeable membranes 421 are provided within the connecting pipe 412, which optimizes the separation of gas and liquid by the gas transmission component 42 and ensures that gas does not spend excessive time passing through the permeable membranes 421. This ensures uniform flow rate within the multiple branch pipes 3 and guarantees the heat exchange effect of the heat exchanger assembly 200.

[0066] In a further embodiment of the present invention, the breathable membrane 421 is a PTFE film. The PTFE film is a film made of polytetrafluoroethylene. It has high strength and low elastic modulus, which is conducive to the formation of complex curved surface shape of the breathable membrane 421, which can better match the connecting pipe 412. In addition, the PTFE film can prevent chemical corrosion and ultraviolet erosion, and is not easy to age. It can improve the service life of the breathable membrane 421 and reduce the maintenance frequency and maintenance cost of the flow equalization component 4. Furthermore, the PTFE film has a micropore diameter of 0.1μm-0.5μm, and the surface of the film can have more than a billion micropores per square centimeter. The diameter of R32 (difluoromethane) liquid molecules is 20μm-100μm, and the diameter of R32 gas molecules is 0.0003μm-0.0004μm. The diameter of each micropore is hundreds of times smaller than the diameter of R32 liquid molecules and tens of thousands of times larger than the diameter of R32 gas molecules, allowing R32 gas molecules to pass through while R32 liquid molecules cannot, thus satisfying the requirement that the flow equalization component 4 only allows gas to flow within multiple branch pipes 3.

[0067] In some embodiments of the present invention, reference is made to the appendix. Figure 1 As shown, the total length of the branch pipe 3 is L3, and the distance between the position where the branch pipe 3 communicates with the flow equalization cavity 411 and the end of the branch pipe 3 closest to the distributor body 1 is L4, satisfying: 0.3≤L4 / L3≤0.8. It should be noted that the position where the branch pipe 3 communicates with the flow equalization cavity 411 is the center plane of the flow equalization component 4 in the thickness direction.

[0068] Understandably, see attached document. Figure 6 As shown, the heat exchange capacity changes with the L4 / L3 ratio under rated cooling and intermediate cooling conditions. When L4 / L3 < 0.3, the position where the branch pipe 3 communicates with the flow equalization chamber 411 is too close to the distributor body 1, the pressure difference in the different branch pipes 3 has not yet appeared, the pressure effect of the flow equalization component 4 is not obvious, and the uniformity cannot be significantly improved. When L4 / L3 > 0.8, the position where the branch pipe 3 communicates with the flow equalization chamber 411 is too close to the heat exchanger body 5, the liquid and gas carry each other, the pressure effect of the flow equalization component 4 is not obvious, and the flow equalization performance cannot be significantly improved. However, when 0.3 ≤ L4 / L3 ≤ 0.8, the position where the branch pipe 3 communicates with the flow equalization chamber 411 is at a suitable distance from the distributor body 1 and the heat exchanger body 5, the pressure difference in the different branch pipes 3 becomes prominent, the gas transmission component 42 can fully exert the pressure effect, and after a period of pressure balance, the pressure in the multiple branch pipes 3 tends to be equal, improving the flow uniformity of the multiple branch pipes 3, and the heat exchange capacity of the heat exchanger assembly 200 can be significantly improved. For example, L4 / L3 can be 0.3, 0.4, 0.5, 0.6, 0.7 or 0.8.

[0069] In some embodiments of the present invention, reference is made to the appendix. Figure 1 As shown, the refrigerant is connected to the flow equalization cavity 411 at the same position on each branch pipe 3, which allows the refrigerant to flow to the flow equalization cavity 411 at the same position in the branch pipe 3. This ensures that the refrigerant in each branch pipe 3 undergoes gas-liquid separation for the same time, and allows the pressure in multiple branch pipes 3 to be balanced as soon as possible, thereby improving the heat exchange capacity of the heat exchanger assembly 200.

[0070] In some embodiments of the present invention, the multiple branch pipes 3 are of the same length, which ensures that the refrigerant in each branch pipe 3 travels the same distance, thus promoting uniform flow rate within the branch pipe 3. Furthermore, the multiple branch pipes 3 have the same diameter, which ensures that the flow quality within the multiple branch pipes 3 is the same, further promoting uniform flow rate within the branch pipe 3. In a specific example, refer to the attached... Figure 1 As shown, the length and diameter of the multiple branch pipes 3 are the same, which can reduce the production and development cost of the branch pipes 3 and facilitate the production and manufacturing of the distributor 100.

[0071] In some embodiments, the multiple branch pipes 3 may have the same length but different diameters; or, the multiple branch pipes 3 may have different lengths but the same diameter; or, the multiple branch pipes 3 may have the same length and diameter. The length and diameter of the multiple branch pipes 3 can be selected according to the actual needs of different distributors 100 to meet different usage requirements.

[0072] Of course, the present invention is not limited to this. The lengths and diameters of the multiple branch pipes 3 may also be different. No further restrictions are imposed here.

[0073] In some embodiments of the present invention, reference is made to the appendix. Figure 1 As shown, multiple branch pipes 3 are evenly spaced along the circumferential direction of the distributor body 1 to make the flow rate in different branch pipes 3 as uniform as possible. The flow equalization component 4 is located in the central space defined by multiple branch pipes 3, so that the flow equalization cavity 411 can be located in the middle of multiple branch pipes 3, which facilitates the flow equalization cavity 411 to communicate with multiple branch pipes 3.

[0074] In some embodiments of the present invention, reference is made to the appendix. Figure 8 and Figure 9 As shown, the flow equalization component 41 may also include a central component 413 and multiple connecting branch pipes 414. Specifically, the central component 413 has a central cavity, and the multiple connecting branch pipes 414 are spaced apart along the circumferential direction of the central component 413 and connected to the central component 413 at one end. Each connecting branch pipe 414 communicates with the central cavity, and the internal space of the multiple connecting branch pipes 414 and the central cavity together form a flow equalization cavity 411. The other ends of the multiple connecting branch pipes 414 are respectively connected to and communicate with multiple branch pipes 3.

[0075] Furthermore, the gas transmission component 42 can also be a gear regulator 43, which is rotatably disposed in the central cavity. There is a gap between the outer wall surface of the gear regulator 43 and the inner wall surface of the central component 413. The diameter of R32 (difluoromethane) liquid molecules is 20μm-100μm, and the diameter of R32 gas molecules is 0.0003μm-0.0004μm. The gap between the outer wall surface of the gear regulator 43 and the inner wall surface of the central component 413 is greater than the maximum diameter of R32 gas molecules (0.0004μm) and less than the minimum diameter of R32 liquid molecules (20μm). This allows the liquid and gas to be separated at the gear regulator 43, allowing only gas to pass through the central cavity while blocking the liquid outside the central cavity, so that the liquid remains in the branch pipe 3 where it is located. This achieves the purpose of allowing only gas to flow between multiple branch pipes 3.

[0076] It should be noted that the number of connecting branch pipes 414 is consistent with the number of branch pipes 3. In a specific example, refer to the appendix... Figure 8 As shown, the flow equalization component 41 includes a central component 413 and three connecting branch pipes 414. The three connecting branch pipes 414 are spaced apart along the circumferential direction of the central component 413 and one end is connected to the central component 413. The other end of the three connecting branch pipes 414 is connected to and communicates with the three branch pipes 3 respectively.

[0077] In some embodiments of the present invention, reference is made to the appendix. Figure 10 As shown, the inner diameter of the connecting branch pipe 414 is D1, and the outer diameter of the gear adjuster 43 is D2, satisfying: 0.8≤D2 / D1≤2.5. For example, D2 / D1 can be 0.8, 1, 1.2, 1.5, 1.7, 2, 2.3, or 2.5.

[0078] Understandably, when D2 / D1 < 0.8, the ratio of D2 / D1 is too small, and the outer diameter D2 of the gear regulator 43 is smaller than the inner diameter D1 of the connecting branch pipe 414. When encountering a large pressure difference between different branch pipes 3, a large amount of gas needs to flow between them. A large amount of gas in the branch pipe 3 with a high flow rate rushes into the central cavity, driving the gear regulator 43 to rotate. Due to the large gas volume, the gear regulator 43 rotates too fast, making it difficult to accurately control the gas to reach the connecting branch pipe 414, thus making it difficult to balance the pressure in different branch pipes 3. Evenly distributing the liquid flow in each branch pipe 3 requires a significant amount of time. When D2 / D1 > 2.5, the ratio of D2 / D1 is too large, and the outer diameter D2 of the gear regulator 43 is much larger than the inner diameter D1 of the connecting branch pipe 414. When encountering different... When the pressure difference between the branch pipes 3 is small, the amount of gas flowing between them is small. A small amount of gas in the branch pipe 3 with a larger flow rate flows into the central cavity. Due to the small amount of gas, the gear regulator 43 may rotate too slowly, or even fail to rotate. This makes it difficult to balance the pressure in the different branch pipes 3, and it takes a lot of time to evenly distribute the liquid flow in each branch pipe 3, or even fail to achieve uniform distribution. However, when 0.8≤D2 / D1≤2.5, the ratio of the outer diameter D2 of the gear regulator 43 to the inner diameter D1 of the connecting branch pipe 414 is appropriate. This can balance the pressure in the different branch pipes 3, making the liquid flow in each branch pipe 3 evenly distributed. This can improve the heat exchange capacity of the heat exchanger assembly 200 and improve the user experience.

[0079] Furthermore, the center component 413 is located along the length of the distributor 100 (see attached diagram). Figure 8 The length in direction a) shown is less than or equal to the outer diameter D1 of the gear adjuster 43, which can prevent excessive accumulation of gas in the central cavity, reduce the time it takes for gas to flow from one branch pipe 3 to another branch pipe 3, and make the pressure in each branch pipe 3 reach uniformity as soon as possible. This will also make the liquid flow in each branch pipe 3 tend to be uniformly distributed as soon as possible, which can improve the heat exchange capacity of the heat exchanger assembly 200 and improve the user experience.

[0080] In some embodiments of the present invention, the multiple connecting branch pipes 414 are of the same length, which ensures that the refrigerant in each connecting branch pipe 414 travels the same distance, thus promoting uniform flow rate within the branch pipe 3. Furthermore, the multiple connecting branch pipes 414 have the same diameter, which ensures that the flow quality within the multiple connecting branch pipes 414 is the same, further promoting uniform flow rate within the branch pipe 3. In a specific example, refer to the attached... Figure 9As shown, the multiple connecting branch pipes 414 have the same length and diameter, which facilitates the production and manufacturing of the flow equalization component 4, reduces the production and development cost of the distributor 100, and the multiple connecting branch pipes 414 with the same length and diameter can form a stable structure, improving the stability of the flow equalization component 4.

[0081] In some embodiments, the multiple connecting branch pipes 414 may have the same length but different diameters; or, the multiple connecting branch pipes 414 may have different lengths but the same diameter; or, the multiple connecting branch pipes 414 may have the same length and diameter. The length and diameter of the multiple connecting branch pipes 414 can be selected according to the actual needs of different distributors 100 to meet different usage requirements.

[0082] Of course, the present invention is not limited to this, and the lengths and diameters of the multiple connecting branch pipes 414 may also be different, without making too many restrictions here.

[0083] The following is for reference. Figures 1 to 3 A dispenser 100 according to a specific embodiment of the present invention is described.

[0084] Specifically, such as Figures 1 to 3 As shown, the distributor 100 includes: a distributor body 1, an inlet and outlet liquid pipe 2, a branch pipe 3, and a flow equalization component 4.

[0085] Furthermore, the distributor body has a distribution chamber. The inlet / outlet pipe 2 and the branch pipe 3 are respectively connected to opposite ends of the distributor body 1, and both the inlet / outlet pipe 2 and the branch pipe 3 are connected to the distribution chamber. There are three branch pipes 3 spaced apart, and the three branch pipes 3 are evenly spaced along the circumferential direction of the distributor body 1 to make the flow rate in different branch pipes 3 as uniform as possible. The flow equalization component 4 is located in the central space defined by the three branch pipes 3 and connected to the three branch pipes 3. The flow equalization component 4 is configured to allow gas to flow only between the three branch pipes 3, limiting the flow of gas in the refrigerant to the three branch pipes 3, while the flow of liquid in the refrigerant cannot flow in multiple branch pipes 3.

[0086] Furthermore, the flow equalization assembly 4 includes a flow equalization element 41 and a gas transmission element 42. The flow equalization element 41 includes three interconnecting pipes 412. One end of the three interconnecting pipes 412 is connected to each other and communicates with each other. The other end of the three interconnecting pipes 412 is connected to three branch pipes 3 respectively and communicates with each other. The space inside the three interconnecting pipes 412 forms a flow equalization cavity 411. The flow equalization cavity 411 communicates with the three branch pipes 3 and the position on each branch pipe 3 that communicates with the flow equalization cavity 411 is the same. Thus, the gas in the three branch pipes 3 can flow to each other through the flow equalization cavity 411 at the same position on the branch pipes 3, so that the refrigerant in each branch pipe 3 undergoes gas-liquid separation for the same time, so that the pressure in the three branch pipes 3 can be balanced as soon as possible, thereby improving the heat exchanger assembly 200. Gas transmission component 42 is located in flow equalization cavity 411. Gas transmission component 42 is a gas permeable membrane 421. Gas permeable membrane 421 is a PTFE film. Each connecting pipe 412 is provided with 3-5 layers of PTFE film. The PTFE film in each connecting pipe 412 is located at the same position in the connecting pipe 412. Only gas can pass through at the same position in each connecting pipe 412, while the liquid remains in the corresponding branch pipe 3.

[0087] Furthermore, the three connecting pipes 412 have the same length and diameter, which facilitates the production and manufacturing of the flow equalization component 4, reduces the production and development cost of the distributor 100, and improves the stability of the flow equalization component 4. The length of the connecting pipe 412 is L1, and the distance between the permeable membrane 421 inside the connecting pipe 412 and the end of the connecting pipe 412 closest to the corresponding branch pipe 3 is L2, satisfying: L2 / L1≥0.3. At this time, the pressure equalization component 4 has a better pressure effect, the pressure in the three branch pipes 3 is balanced, and the flow rate in the different branch pipes 3 tends to be uniform, which can improve the heat exchanger assembly 200.

[0088] In addition, the three branch pipes 3 have the same length and diameter, which can reduce the production and development cost of the branch pipes 3 and facilitate the production and manufacturing of the distributor 100. The total length of the branch pipe 3 is L3, and the distance between the position where the branch pipe 3 communicates with the flow equalization cavity 411 and the end of the branch pipe 3 closest to the distributor body 1 is L4, which satisfies: 0.3≤L4 / L3≤0.8. At this time, the position where the branch pipe 3 communicates with the flow equalization cavity 411 is at an appropriate distance from the distributor body 1 and the heat exchanger body 5, and the pressure difference between the different branch pipes 3 is prominent. The PTFE membrane can give full play to the pressure effect. After a period of pressure balance, the pressure in the three branch pipes 3 tends to be equal, which improves the flow uniformity of the three branch pipes 3, and the heat exchange capacity of the heat exchanger assembly 200 can be significantly improved.

[0089] The present invention also proposes a heat exchanger assembly 200 having the distributor 100 of the above embodiments.

[0090] Specifically, see the attached document. Figure 4 As shown, the heat exchanger assembly 200 includes a heat exchanger body 5 and the aforementioned distributor 100. The refrigerant enters the distribution chamber of the distributor body 1 through the inlet / outlet liquid pipe 2, and then flows to the heat exchanger body 5 from multiple branch pipes 3. After heat exchange, the refrigerant flows out of the heat exchanger body 5 and merges to complete the heat exchange.

[0091] According to an embodiment of the present invention, the heat exchanger assembly 200 connects multiple branch pipes 3 via a flow equalization assembly 4, and the flow equalization chamber 411 connects the multiple branch pipes 3. The flow equalization assembly 4 only allows gas to flow between the multiple branch pipes 3, and allows gas to flow from one branch pipe 3 to another branch pipe 3 through the flow equalization chamber 411, thereby keeping the pressure in different branch pipes 3 consistent. As a result, the liquid flow rate in each branch pipe 3 eventually tends to be uniformly distributed, which can improve the heat exchange capacity of the heat exchanger assembly 200, ensure the heating or cooling effect of the air conditioner, and improve the user experience.

[0092] The present invention also proposes an air conditioner having the heat exchanger assembly 200 of the above embodiments.

[0093] In a specific example, see Appendix Figure 7 As shown, compared with the prototype in the prior art, the air conditioner using the distributor 100 of this embodiment of the invention has a heat exchange capacity increased by 134W under rated cooling conditions and an heat exchange capacity increased by 86W under intermediate cooling conditions. The heat exchange capacity of the air conditioner has been significantly improved, which can improve the user experience.

[0094] According to an embodiment of the present invention, an air conditioner connects multiple branch pipes 3 via a flow equalization assembly 4, and connects multiple branch pipes 3 via a flow equalization cavity 411. The flow equalization assembly 4 only allows gas to flow between multiple branch pipes 3, allowing gas to flow from one branch pipe 3 to another through the flow equalization cavity 411, thereby keeping the pressure in different branch pipes 3 consistent, and ultimately making the liquid flow rate in each branch pipe 3 tend to be uniformly distributed. This can improve the heat exchange capacity of the heat exchanger assembly 200, ensure the heating or cooling effect of the air conditioner, and improve the user experience.
