[0071] An integrated shunt 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0072] like Figure 1-Figure 5 As shown, the integrated distributor 100 according to an embodiment of the present utility model is used in a heat exchanger. The integrated distributor 100 is disposed at one end of the heat exchanger and includes a housing 1, a partition 2, a first manifold 3, a second manifold 4 and an embedded pipe assembly 5.

[0073] Specifically, such as Figure 1-Figure 3As shown, the housing 1 extends along a first direction and includes a housing body 11, a top plate 12, and a bottom plate 13. The housing body 11 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 are rectangular flat plate structures and all extend along the first direction. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 are connected end to end to form a rectangle whose axis extends along the first direction. The two ends of the first plate 111 in the width direction are respectively connected to one end of the second plate 112 and the fourth plate 114 in the width direction. The third plate 113 is parallel to the first plate 111 and spaced apart. The two ends of the third plate 113 in the width direction are respectively connected to the other ends of the second plate 112 and the fourth plate 114 in the width direction. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 form the external frame of the integrated splitter 100.

[0074] Furthermore, such as Figure 1 and Figure 2 As shown at the end, the second plate 112 and the fourth plate 114 are located between the first plate 111 and the third plate 113. That is, the two end faces of the second plate 112 in the width direction are respectively attached to the surfaces of the first plate 111 and the third plate 113 facing each other, and the two end faces of the fourth plate 114 in the width direction are respectively attached to the surfaces of the first plate 111 and the third plate 113 facing each other. The surfaces of the second plate 112 and the fourth plate 114 away from each other are respectively flush with the two end faces of the first plate 111 and the third plate 113 in the width direction.

[0075] like Figure 1 and Figure 2 As shown, the top plate 12 and the bottom plate 13 are respectively disposed at both ends of the shell body 11 in a first direction to seal the open openings at both ends of the shell body 11. The top plate 12 is connected to one end of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 in the length direction, and the bottom plate 13 is connected to the other end of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 in the width direction. Additionally, as... Figure 1 and Figure 2 As shown, the surfaces of the bottom plate 13 and the top plate 12 that are opposite to each other are flush with the two end faces of the first plate 111, the second plate 112, the third plate 113 and the fourth plate 114 in the length direction.

[0076] Optionally, the two interconnected components in the first plate 111, the second plate 112, the third plate 113, the fourth plate 114, the top plate 12, and the bottom plate 13 are all welded together.

[0077] like Figure 4 and Figure 5As shown, the partition 2 is disposed inside the housing 1 to divide the internal cavity of the housing 1 into multiple diversion chambers 14 spaced apart along a first direction. Specifically, the partition 2 is located inside and connected to the housing body 11. The partition 2 is arranged parallel to the top plate 12 and the bottom plate 13, and perpendicular to the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114. The partition 2 is welded to the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114.

[0078] like Figure 1-Figure 4 As shown, for reference Figure 7 , Figure 9 and Figure 11 As shown, the first manifold 3 passes through the housing 1 and the partition 2 along a first direction, and has multiple first connection holes 31 located in multiple branch chambers 14. It is understood that each branch chamber 14 has a first connection hole 31. The second manifold 4 passes through the housing 1 and the partition 2 along a first direction, and has multiple second connection holes 41 located in multiple branch chambers 14. It is understood that each branch chamber 14 has a second connection hole 41.

[0079] In addition, such as Figure 8 and Figure 9 As shown, the partition 2 has a first through hole 21 for the first manifold 3 to pass through, and a second through hole 22 for the second manifold 4 to pass through. This facilitates the first manifold 3 to pass through the first through hole 21 and the second manifold 4 to pass through the second through hole 22 on the partition 2.

[0080] like Figures 4-5 As shown, there are multiple embedded tube assemblies 5 corresponding to multiple flow distribution chambers 14. The embedded tube assemblies 5 are inserted into the housing 1 along the second direction. Specifically, the embedded tube assemblies 5 are inserted into the first plate 111. The embedded tube assemblies 5 have a first connection port 511 and a second connection port 521 located in the flow distribution chamber 14. The first connection port 511 communicates with the first connection hole 31, and the second connection port 521 communicates with the second connection hole 41. The opening of the embedded tube assembly 5 outside the housing 1 is suitable for connecting with the heat exchange tube on the heat exchanger.

[0081] Refrigerant can flow in through the first manifold 3, and through the connection between the first connecting hole 31 and the first connecting port 511, the refrigerant can flow into the flow path formed by the heat exchange tubes of the heat exchanger connected to the embedded tube assembly 5. Then, it flows out through the connection between the second connecting port 521 and the second connecting hole 41 into the second manifold 4, and then flows out through the second manifold 4. The heat exchange tubes of the heat exchanger can include multiple heat exchange flow paths, and the multiple heat exchange flow paths correspond one-to-one with multiple flow distribution chambers 14. The refrigerant flowing into the first manifold 3 can flow into multiple embedded tube assemblies 5 and then into the corresponding heat exchange flow path of the heat exchanger. After heat exchange is completed in the heat exchanger, the refrigerant in the multiple heat exchange flow paths flows into the second manifold 4 through the embedded tube assembly 5.

[0082] Optionally, the embedded tube assembly 5 can be welded to the housing 1, for example, the first plate 111.

[0083] In this application, the embedded tube assembly 5 can be pre-assembled with the housing 1 and welded together, and the first manifold 3 and the second manifold 4 can also be pre-assembled with the housing 1 and welded together, so that the entire integrated splitter 100 is integrated into a single structure. When connecting the integrated splitter 100 to the heat exchanger, the opening of the embedded tube assembly 5 located outside the housing 1 can be directly welded to the interface of the corresponding heat exchange tube on the heat exchanger, simplifying the heat exchanger assembly manufacturing process, optimizing the welding process, and realizing the modular manufacturing of the integrated splitter 100.

[0084] According to the integrated flow divider 100 of this utility model embodiment, by providing a partition 2 inside the housing 1 to divide the cavity inside the housing 1 into a plurality of flow divider chambers 14 spaced apart along the length direction of the housing 1, and by providing a first manifold 3 and a second manifold 4 through the housing 1 and the partition 2, and by providing an embedded tube assembly 5 embedded in the housing 1 and having a first connection port 511 communicating with the first connection hole 31 of the first manifold 3 and a second connection port 521 communicating with the second manifold 4, the integrated flow divider 100 can be modularized. When connected to a heat exchanger, the opening of the embedded tube assembly 5 located outside the housing 1 can be directly connected to the heat exchanger tube interface of the heat exchanger, simplifying the heat exchanger assembly manufacturing process and optimizing the welding process.

[0085] In some embodiments of this utility model, such as Figures 8-11As shown, the first connection port 511 and the first connection hole 31 are spaced apart and both are connected to the flow distribution cavity 14. It can be understood that the first connection port 511 and the first connection hole 31 can be connected through the flow distribution cavity 14. When the refrigerant flows in from the first manifold 3, it flows through the first connection hole 31 into the flow distribution cavity 14. The refrigerant in the flow distribution cavity 14 then flows through the first connection port 511 into the heat exchange path formed by the embedded tube assembly 5 and the heat exchange tubes of the heat exchanger. When the heat exchanger is used as an evaporator, the refrigerant can flow in from the first manifold 3. The spaced arrangement of the first connection hole 31 and the first connection port 511, connected through the flow distribution cavity 14, allows for a more uniform flow distribution into the first connection ports 511 of the multiple embedded tube assemblies 5, ensuring the uniformity of heat exchange in the heat exchanger.

[0086] In some embodiments of this utility model, such as Figures 8-11 As shown, each distribution cavity 14 has multiple first connection holes 31, thereby increasing the flow rate of refrigerant from the first manifold 3 to the distribution cavity 14. The multiple first connection holes 31 within the same distribution cavity 14 can be spaced apart along the length of the first manifold 3 or spaced apart along the circumferential direction of the first manifold 3. For example, in... Figure 6 and Figure 7 In the example shown, each shunt cavity 14 has two first connection holes 31, which are arranged at intervals in the circumferential direction of the first manifold 3. Specifically, the two first connection holes 31 are evenly spaced apart in the circumferential direction of the first manifold 3, that is, they are arranged opposite each other in the radial direction of the first manifold 3.

[0087] In some embodiments of this utility model, such as Figure 12 and Figure 13 As shown, the portion of the embedded tube assembly 5 with the first connection port 511 (the first connecting tube described below) is embedded in the housing 1 for a length L4, which is 3mm-5mm. For example, the length L4 of the portion of the embedded tube assembly 5 with the first connection port 511 embedded in the housing 1 can be 3.3mm, 3.5mm, 3.7mm, 3.9mm, 4mm, 4.3mm, 4.5mm, 4.7mm, 4.9mm, or 5mm, etc. This ensures the reliability of the embedded tube assembly 5 in fixing to the housing 1, and also ensures that the refrigerant in the distribution cavity 14 can flow smoothly into the first connection port 511.

[0088] In some embodiments of this utility model, such as Figure 8 and Figure 11 As shown, the second connection port 521 and the second connection hole 41 are connected. This facilitates the flow of refrigerant from the heat exchanger's heat exchange path through the embedded tube assembly 5 into the second manifold 4. For example, the second connection port 521 and the second manifold 4 can be connected by a tee device, such as a tee pipe.

[0089] In some embodiments of this utility model, such as Figures 8-11 As shown, the embedded tube assembly 5 includes a first connecting tube 51 and a second connecting tube 52. Both the first connecting tube 51 and the second connecting tube 52 are inserted into the housing 1. The openings of the first connecting tube 51 and the second connecting tube 52 located in the flow distribution cavity 14 are respectively configured as a first connection port 511 and a second connection port 521. The end of the first connecting tube 51 facing away from the first connection port 511 and the end of the second connecting tube 52 facing away from the second connection port 521 are located outside the housing 1. The ends of the first connecting tube 51 and the second connecting tube 52 located outside the housing 1 are used to connect to the heat exchange tubes on the heat exchanger.

[0090] For example, the heat exchanger has multiple heat exchange tubes, which form multiple heat exchange flow paths. Each heat exchange flow path may include a U-shaped tube, the two ends of which can be connected to the ends of the first connecting pipe 51 and the second connecting pipe 52 located outside the shell 1, respectively. Of course, each heat exchange flow path may also include multiple U-shaped tubes, which can be connected by a bend. The bend can be located outside the shell 1. The ends of the two U-shaped tubes located at both ends of the heat exchange flow path that are opposite to each other can be connected to the ends of the first connecting pipe 51 and the second connecting pipe 52 located outside the shell 1, respectively.

[0091] Of course, this utility model is not limited to this, such as Figures 8-11 As shown, the embedded tube assembly 5 may also include a third connecting tube 53, which is inserted through the housing 1 and the openings at both ends of the third connecting tube 53 are located outside the housing 1. When the heat exchange flow path includes multiple U-shaped tubes, two adjacent U-shaped tubes can be connected through the third connecting tube 53.

[0092] The third connecting pipe 53 can be one or more, and the number of third connecting pipes 53 can be one less than the number of U-shaped pipes in the heat exchange flow path. Multiple U-shaped pipes are interconnected through multiple third connecting pipes 53. When the integrated flow divider 100 is connected to the heat exchange tubes of the heat exchanger, the interfaces of the first connecting pipe 51, the second connecting pipe 52, and the third connecting pipe 53 located outside the shell 1 can be aligned and welded with the interfaces of the corresponding heat exchange tubes. This realizes the modularity of the integrated flow divider 100, simplifies the heat exchanger component manufacturing process, and optimizes the welding process.

[0093] Optionally, such as Figures 8-9 As shown, the third connecting pipe 53 is a U-shaped pipe. The bent section of the third connecting pipe 53 is located inside the housing 1, and the two straight sections of the third connecting pipe 53 pass through the housing 1.

[0094] In some embodiments of this utility model, such as Figure 3 , Figure 6 and Figure 7As shown, the openings of the embedded tube assembly 5 outside the shell 1 are arranged in two rows along the third direction. The two rows of openings are staggered in the first direction, and the first, second, and third directions are perpendicular to each other. The heat exchange tubes on the heat exchanger are generally arranged in two rows along the thickness direction of the heat exchanger. The two rows of heat exchange tubes are staggered in the height direction of the heat exchanger, so that the openings of the embedded tube assembly 5 outside the shell 1 are arranged in two rows along the third direction. The staggered arrangement of the two rows of openings in the first direction can better match with the heat exchange tubes on the heat exchanger. When the integrated separator 100 is connected to the heat exchanger, the openings of the corresponding embedded tube assembly 5 and the openings of the heat exchange tubes can be directly aligned, which facilitates the connection between the integrated separator and the heat exchanger.

[0095] In some embodiments of this utility model, such as Figure 4 As shown, the partitions 2 are multiple and spaced apart along the first direction. This divides the cavity inside the shell 1 into at least three flow channels 14, thereby enabling the heat exchanger to have multiple parallel heat exchange flow paths and improving the heat exchanger's heat exchange efficiency.

[0096] In some embodiments of this utility model, such as Figure 7 and Figure 9 As shown, the inner diameter of the first manifold 3 is larger than the inner diameter of the second manifold 4. The second manifold 4 can be used as a gas pipe. When the heat exchanger is used as a condenser, the high-temperature and high-pressure refrigerant discharged from the compressor can flow to the heat exchanger through the second manifold 4 for heat exchange. The larger inner diameter of the first manifold 3 is more suitable for the flow of the refrigerant.

[0097] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the first manifold 3 and the second manifold 4 are inserted into the housing 1 from both ends in the first direction. The first manifold 3 is inserted into the housing 1 from one end, and the end of the first manifold 3 at the other end of the housing 1 is a closed end. The second manifold 4 is inserted into the housing 1 from one end, and the end of the second manifold 4 at the other end of the housing 1 is a closed end. This facilitates the connection between the first manifold 3 and the second manifold 4 and other pipelines, and avoids the first manifold 3 and the second manifold 4 from piling up together, which would affect the connection with other pipelines.

[0098] For example, in Figure 1 and Figure 2In the example shown, the first manifold 3 is installed on the base plate 13, the second manifold 4 is installed on the base plate 13, the third through hole 131 on the base plate 13 for the first manifold 3 to pass through and the first through hole 21 on the partition plate 2 for the first manifold 3 to pass through are aligned in the first direction, the second manifold 4 is installed on the top plate 12, the third through hole 131 on the top plate 12 for the second manifold 4 to pass through and the second through hole 22 on the partition plate 2 for the second manifold 4 to pass through are aligned in the first direction.

[0099] In some embodiments of this utility model, in the direction from one end of the first manifold 3 extending out of the housing 1 to the other end, the total area of ​​the first connecting holes 31 within the plurality of diversion chambers 14 gradually increases. (Refer to...) Figure 15 As shown in Table 1, when refrigerant flows into the heat exchanger from the first manifold 3, the refrigerant flow rate is greater at the first connecting hole 31 closer to the inlet end of the first manifold 3, resulting in uneven refrigerant distribution in the multiple heat exchange flow paths that cooperate with the multiple embedded tube assemblies 5 within the heat exchanger. In this application, the total area of ​​the first connecting holes 31 in the multiple distribution chambers 14 gradually increases in the direction from one end of the first manifold 3 extending out of the housing 1 to the other end. This allows for a more uniform distribution of refrigerant flow rate in the first connecting holes 31 within the multiple distribution chambers 14, thereby making the refrigerant distribution in the multiple heat exchange flow paths that cooperate with the multiple embedded tube assemblies 5 on the heat exchanger more uniform and ensuring the uniformity of heat exchange in the heat exchanger. The distribution chambers 14 in Table 1 are numbered sequentially starting from the side closest to the inlet end of the first manifold 3.

[0117] The following describes a heat exchanger assembly according to an embodiment of the present invention.

[0118] Specifically, the heat exchanger assembly according to this utility model embodiment includes a heat exchanger and the aforementioned integrated distributor 100. The heat exchanger has multiple U-shaped heat exchange tubes, and the interfaces of the multiple U-shaped heat exchange tubes are located on the same side of the heat exchanger. The integrated distributor 100 is located at one end of the heat exchanger, for example, at one end of the interface of the U-shaped heat exchange tube on the heat exchanger. The opening of the embedded tube assembly 5 located outside the housing 1 is connected to the interface of the U-shaped heat exchange tube.

[0119] This avoids the need to separately connect the first manifold 3 and the second manifold 4 to the embedded tube assembly 5, and to connect the first connecting tube 51 and the second connecting tube 52 to the U-shaped tube. The integrated splitter 100 can be directly integrated into a module. When connecting, only the end of the embedded tube assembly 5 located outside the housing 1 needs to be connected to the U-shaped heat exchange tube on the heat exchanger.

[0120] According to the heat exchanger assembly of this utility model embodiment, by setting the above-mentioned integrated distributor 100, a partition 2 is set in the shell 1 to divide the cavity in the shell 1 into a plurality of distributor cavities 14 spaced apart along the length direction of the shell 1, and the first manifold 3 and the second manifold 4 pass through the shell 1 and the partition 2. An embedded tube assembly 5 is set on the shell 1 and has a first connection port 511 communicating with the first connection hole 31 of the first manifold 3 and a second connection port 521 communicating with the second manifold 4. The integrated distributor 100 can be modularized. When connected to the heat exchanger, the opening of the embedded tube assembly 5 located outside the shell 1 is directly connected to the heat exchange tube interface of the heat exchanger, simplifying the heat exchanger assembly manufacturing process and optimizing the welding process.

[0121] In some embodiments of this invention, the straight section of the U-shaped heat exchange tube extends along a second direction, and the shell 1 is located on one side of the heat exchanger along the second direction. The height direction of the heat exchanger is the same as that of the first direction. This facilitates the connection between the U-shaped heat exchange tube and the embedded tube assembly 5 of the integrated distributor 100, simplifies the manufacturing process of the heat exchanger assembly, and optimizes the welding process.

[0122] For example, when the integrated splitter 100 is connected to the heat exchanger, the integrated splitter 100 is placed at one end of the heat exchanger, and the opening of the embedded tube assembly 5 on the integrated splitter 100 outside the shell 1 and the interface of the U-shaped heat exchange tube on the heat exchanger are arranged opposite to each other. Then, they can be welded together using processing equipment to improve welding efficiency.

[0123] The following describes an outdoor unit of an air conditioner according to an embodiment of the present invention.

[0124] The outdoor unit of the air conditioner according to an embodiment of the present invention includes the heat exchanger assembly described above.

[0125] According to the embodiment of the present utility model, the outdoor unit of the air conditioner is equipped with the above-mentioned heat exchanger assembly, which includes the above-mentioned integrated separator. A partition 2 is provided in the housing 1 to divide the cavity in the housing 1 into a plurality of flow distribution chambers 14 spaced apart along the length of the housing 1. The first manifold 3 and the second manifold 4 pass through the housing 1 and the partition 2. An embedded tube assembly 5 is provided and embedded in the housing 1, having a first connection port 511 communicating with the first connection hole 31 of the first manifold 3 and a second connection port 521 communicating with the second manifold 4. The integrated flow distribution unit 100 can be modularized. When connected to the heat exchanger, the opening of the embedded tube assembly 5 located outside the housing 1 is directly connected to the heat exchange tube interface of the heat exchanger, simplifying the manufacturing process of the heat exchanger assembly and optimizing the welding process.

[0126] The following describes an air conditioner according to an embodiment of the present invention.

[0127] The air conditioner according to an embodiment of the present invention includes the above-described outdoor air conditioner unit.

[0128] According to the embodiment of the present invention, the air conditioner includes an outdoor unit, which comprises a heat exchanger assembly and an integrated distributor 100. A partition 2 is provided inside the housing 1 to divide the cavity inside the housing 1 into multiple distributor chambers 14 spaced apart along the length of the housing 1. The first manifold 3 and the second manifold 4 pass through the housing 1 and the partition 2. An embedded tube assembly 5 is provided and embedded in the housing 1, having a first connection port 511 communicating with the first connection hole 31 of the first manifold 3 and a second connection port 521 communicating with the second manifold 4. The integrated distributor 100 can be modularized. When connected to the heat exchanger, the opening of the embedded tube assembly 5 located outside the housing 1 is directly connected to the heat exchanger tube interface of the heat exchanger, simplifying the manufacturing process of the heat exchanger assembly and optimizing the welding process.

[0129] In some embodiments of this utility model, the air conditioner further includes an indoor unit, which contains an indoor heat exchanger. The outdoor unit also contains a compressor, a gas-liquid separator, and a reversing assembly. The gas-liquid separator has a first inlet / outlet, a second inlet / outlet, and a gas outlet. The first inlet / outlet is located on the peripheral wall of the gas-liquid separator, the second inlet / outlet is located on the bottom wall of the gas-liquid separator, and the gas outlet is located on the top wall of the gas-liquid separator. The compressor has an exhaust port and a return port. The reversing assembly has a first port, a second port, a third port, and a fourth port. One of the first port, the second port, and the third port is connected, and the fourth port is connected to the other of the second port and the third port. The first port is connected to the exhaust port, and the fourth port is connected to the return port. One end of the second manifold 4 is connected to the second port, one end of the indoor heat exchanger is connected to the third port, and the other end of the indoor heat exchanger is connected to the first inlet / outlet. One end of the first manifold 3 is connected to the second inlet / outlet, and the gas outlet is connected to the second port.

[0130] In evaporation mode, i.e., when the heat exchanger acts as an evaporator, during the heating operation of the indoor unit of the air conditioner, the refrigerant undergoes gas-liquid separation by the gas-liquid separator. The separated liquid refrigerant then enters the first manifold 3, allowing for more uniform distribution of the refrigerant as it flows into the distribution chamber 14. Additionally, the refrigerant in the first manifold 3 flows into the heat exchange path of the heat exchanger for heat exchange. After absorbing heat, the refrigerant merges with the second manifold 4 and flows out of the integrated distributor 100. In condensation mode, i.e., when the heat exchanger acts as a condenser, during the cooling operation of the indoor unit of the air conditioner, the gaseous refrigerant flows into the integrated distributor 100 through the second manifold 4, releases heat, condenses, and then merges with the first manifold 3 and flows out of the integrated distributor 100.

[0131] In some embodiments of this invention, the gas-liquid separator has a spiral structure. The first inlet and outlet are located on the bottom wall of the spiral groove of the spiral structure, and the spiral structure extends spirally along the vertical direction of the gas-liquid separator. Two-phase flows enter the gas-liquid separator and are guided downwards by the spiral structure. Under the action of gravity and centrifugal force, the liquid phase accumulates near the wall and flows out from the lower second inlet and outlet, while the gas phase accumulates at the center of the phase separator and flows out from the upper gas outlet.

[0132] Other components of the air conditioner according to the embodiments of the present invention, such as the fan assembly and the air guide assembly, as well as its operation, are known to those skilled in the art and will not be described in detail here.

[0133] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention.
