Description

Technical Field

[0002] In related technologies, heat exchangers, as essential components of air conditioning systems, serve as both evaporators and condensers. To improve the performance of air conditioning systems and adapt heat exchangers to different operating modes, existing heat exchanger structures and refrigerant flow paths within them are becoming increasingly complex. Using ordinary flow dividers cannot meet the requirements of different flow path changes within the heat exchanger, resulting in a single flow path and a decrease in heat exchanger capacity. Furthermore, uneven flow within the flow divider also leads to uneven refrigerant flow into different flow paths within the heat exchanger, further reducing its capacity. Utility Model Content

[0072] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0073] The following is for reference. Figures 1-8 Description of a shunt component 100 according to an embodiment of the present utility model.

[0074] like Figures 1-8 As shown, the diversion component 100 according to an embodiment of the present utility model includes: a main body 1 and a flow-blocking component 2.

[0075] Specifically, refer to Figures 1-8 The main body 1 has a first port 11, a second port 12, a first connecting hole 13, and a second connecting hole 14; the flow-blocking component 2 is provided on the main body 1. Along the length direction of the main body 1, the first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2, the second port 12 and the second connecting hole 14 are located on the same side of the flow-blocking component 2, and the first port 11 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows the refrigerant to flow from the second port 12 side to the first connecting hole 13 side.

[0076] It should be noted that the flow distribution component 100 is used in the heat exchanger body 4, which has multiple heat exchange tubes 41. The heat exchange tubes 41 and the body 1 form a flow channel for the refrigerant, which can be a refrigerant. In a specific example, such as... Figure 1 As shown, the first connecting hole 13 and the second connecting hole 14 are both provided on the peripheral wall of the body part 1 and are spaced apart along the length direction of the body part 1. The first port 11 and the second port 12 are respectively provided at both ends of the length direction of the body part 1, or the first port 11 and the second port 12 are both provided on the peripheral wall of the body part 1 and located on both sides of the flow blocking member 2.

[0077] The flow-blocking component 2 is unidirectional. It only opens when the pressure on the side of the flow-blocking component 2 closest to the second port 12 is greater than the pressure on the side of the flow-blocking component 2 closest to the first port 11, allowing the refrigerant to flow from the second port 12 to the first port 11. When the refrigerant enters the main body 1 from the second port 12, the flow-blocking component 2 opens, and part of the refrigerant flows from the second port 12 to the second connecting hole 14 and enters the heat exchange tube 41, while part of the refrigerant flows through the flow-blocking component 2 to the first connecting hole 13 and enters the heat exchange tube 41.

[0078] When the refrigerant enters the main body 1 from the first port 11, the flow-blocking component 2 is not conductive, and the refrigerant cannot flow from the end of the flow-blocking component 2 near the first port 11 to the end of the flow-blocking component 2 near the second port 12. The refrigerant can only flow from the first port 11 to the first connecting hole 13, then enter the heat exchange tube 41, and then return to the main body 1 from the heat exchange tube 41 through the second connecting hole 14, and finally flow out of the heat exchanger assembly 200 from the second port 12.

[0079] This application adds a flow-blocking component 2 to the flow-dividing assembly 100. The flow-blocking component 2 automatically opens, closes, or cuts off the flow based on the pressure difference of the refrigerant on both sides, thereby enabling automatic flow guidance of the refrigerant and changing its flow direction. When the flow-dividing assembly 100 is used in the heat exchanger assembly 200 of the air conditioning system 300, it can automatically switch the refrigerant flow path within the heat exchanger assembly 200 in different modes of the air conditioning system 300, thereby improving the heat exchange efficiency of the heat exchanger assembly 200, enhancing the cooling or heating performance of the air conditioning system 300, and improving energy efficiency. Furthermore, it eliminates the need for other control structures, is less susceptible to power failures, and features a simple, easy-to-implement, and low-cost structure.

[0080] Furthermore, such as Figure 1 As shown, at least one first branch pipe 31 is connected to the first connecting hole 13. The first branch pipe 31 is connected to the main body 1 and communicates with the first connecting hole 13. The first branch pipe 31 can be used to indirectly connect the main body 1 to the heat exchange tube 41 of the heat exchanger assembly 200, which can relatively reduce the difficulty of connecting the flow distribution assembly 100 and the heat exchange tube 41, reduce the probability of refrigerant leakage, and ensure the normal operation of the heat exchanger assembly 200.

[0081] refer to Figure 1 and Figure 2 As shown, there are three first branch pipes 31. Furthermore, there are two first connecting holes 13, one of which connects to one first branch pipe 31, and the other connects to two first branch pipes 31. Of course, there can also be one, two, four, five, or six first branch pipes 31, etc., and each first connecting hole 13 can connect to one, two, three, four, five, or six first branch pipes 31, etc.

[0082] It should be noted that the welding connection between the multiple first branch pipes 31 and the main body 1 can ensure the connection strength between the first branch pipes 31 and the main body 1, improve the structural strength of the diversion assembly 100, and ensure the reliability and stability of the diversion assembly 100. Furthermore, during the welding process, the weld metal fills the gap between the main body 1 and the first branch pipes 31, forming a dense connection layer, which can effectively prevent refrigerant leakage.

[0083] Furthermore, such as Figure 1 As shown, at least one second branch pipe 32 is connected to the second connecting hole 14. The second branch pipe 32 is connected to the main body 1 and communicates with the second connecting hole 14. The second branch pipe 32 can be used to indirectly connect the main body 1 to the heat exchange tube 41 of the heat exchanger assembly 200, which can relatively reduce the difficulty of connecting the flow distribution assembly 100 and the heat exchange tube 41, reduce the probability of refrigerant leakage, and ensure the normal operation of the heat exchanger assembly 200.

[0084] Specifically, the second branch pipe 32 can be one, two, three, four, five or six, etc., and each second connecting hole 14 can be connected to one, two, three, four, five or six, etc.

[0085] It should be noted that the welding connection between the multiple second branch pipes 32 and the main body 1 can ensure the connection strength between the second branch pipes 32 and the main body 1, improve the structural strength of the diversion assembly 100, and ensure the reliability and stability of the diversion assembly 100. In addition, during the welding process, the weld metal fills the gap between the main body 1 and the second branch pipes 32, forming a dense connection layer, which can effectively prevent refrigerant leakage.

[0086] Furthermore, such as Figure 1 As shown, the second branch pipe 32 has a bend 326. It can be understood that the bend 326 in the second branch pipe 32 increases the resistance to refrigerant entering the second branch pipe 32, allowing more refrigerant to continue flowing towards the first connecting hole 13 after passing through the flow-blocking component 2, thus meeting the flow requirements of the first connecting hole 13. This better achieves the flow-dividing effect, improves the uneven flow distribution caused by refrigerant dynamic pressure, and enhances the flow-dividing effect of the flow-dividing assembly 100. When the flow-dividing assembly 100 is applied to the heat exchanger assembly 200 and the air conditioning system 300, it can improve the heat exchange efficiency of the heat exchanger assembly 200, improve the cooling or heating performance of the air conditioning system 300, and improve energy efficiency.

[0087] According to the flow divider assembly 100 of this utility model embodiment, along the length direction of the main body 1, the first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2, the second port 12 and the second connecting hole 14 are located on the same side of the flow-blocking component 2, and the first port 11 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows refrigerant to flow from the second port 12 side to the first port 11 side. At least one first branch pipe 31 is connected to the first connecting hole 13, and the first branch pipe 31 is connected to the main body 1 and communicates with the first connecting hole 13. At least one second branch pipe 32 is connected to the second connecting hole 14. The second branch pipe 32 is connected to the main body 1 and communicates with the second connecting hole 14. It can realize the automatic switching of different flow paths of refrigerant in heat exchanger assembly 200 in different modes of air conditioning system 300. The second branch pipe 32 has a bend 326, thereby improving the problem of uneven flow due to refrigerant dynamic pressure, improving the flow distribution effect of flow distribution assembly 100, thereby improving the heat exchange efficiency of heat exchanger assembly 200, improving the cooling or heating performance of air conditioning system 300, and improving energy efficiency.

[0088] In some embodiments of this utility model, such as Figures 1-4As shown, the second branch pipe 32 has multiple sub-pipes connected in sequence, with adjacent sub-pipes forming a bend 326 at an angle to each other. It should be noted that the second branch pipe 32 can be formed by bending into multiple sub-pipes, or by welding multiple independent sub-pipes in sequence.

[0089] The two adjacent sub-pipes form a bend 326 at an angle, which increases the resistance to the refrigerant entering the second branch pipe 32. This allows more refrigerant to continue flowing towards the first connecting hole 13 after passing through the flow-blocking component 2, thus meeting the flow requirements of the first connecting hole 13. This better achieves the flow-dividing effect, improves the uneven flow distribution caused by refrigerant dynamic pressure, and enhances the flow-dividing effect of the flow-dividing component 100. When the flow-dividing component 100 is applied to the heat exchanger assembly 200 and the air conditioning system 300, it can improve the heat exchange efficiency of the heat exchanger assembly 200, improve the cooling or heating performance of the air conditioning system 300, and improve energy efficiency.

[0090] For example in Figure 2 and Figure 4 In the example shown, the second branch pipe 32 has three sub-pipes. Figure 3 In the example shown, the second branch pipe 32 has two sub-pipes, but the present invention is not limited to this. The second branch pipe 32 may also have more sub-pipes, such as 4, 5, 6 or 7 sub-pipes.

[0091] In some embodiments of this utility model, such as Figures 1-4 As shown, the multiple sub-pipes include a first sub-pipe 321 and a second sub-pipe 322 connected in sequence. One end of the first sub-pipe 321 is connected to the second connecting hole 14, and the first sub-pipe 321 and the second sub-pipe 322 are perpendicular. It can be understood that when the first sub-pipe 321 and the second sub-pipe 322 are perpendicular, on the one hand, the resistance of the bend 326 between the first sub-pipe 321 and the second sub-pipe 322 can be sufficiently large, thereby further improving the problem of uneven flow distribution caused by refrigerant dynamic pressure and improving the flow distribution effect of the flow distribution assembly 100. On the other hand, it can prevent the bend 326 between the first sub-pipe 321 and the second sub-pipe 322 from being too large and breaking.

[0092] In some embodiments of this utility model, such as Figures 1-4As shown, a first arc-shaped section 324 is provided between the first sub-pipe 321 and the second sub-pipe 322. It is understood that the arc-shaped design helps maintain uniform and stable airflow, reducing turbulence and eddies caused by sudden changes in direction, and improving the efficiency of the air conditioning system 300. The airflow is smoother as it passes through the first arc-shaped section 324, which helps reduce noise caused by airflow turbulence. Furthermore, the first arc-shaped section 324 reduces the impact and wear of the refrigerant on the inner wall of the pipe, extending the service life of the inlet and outlet pipes 34. The first arc-shaped section 324 makes the installation of the first sub-pipe 321 and the second sub-pipe 322 more flexible, making it easier to adapt to space constraints and layout requirements. The first arc-shaped section 324 helps prevent the accumulation of dust and debris inside the pipe, reducing maintenance problems caused by blockages, and also helps reduce damage to system components caused by impacts and vibrations.

[0093] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the multiple sub-tubes also include a third sub-tube 323. One end of the third sub-tube 323 is connected to the end of the second sub-tube 322 that is away from the first sub-tube 321. The third sub-tube 323 is perpendicular to the second sub-tube 322. The first sub-tube 321 and the third sub-tube 323 are located on opposite sides of the second sub-tube 322.

[0094] Understandably, by adding the third sub-pipe 323, the resistance to refrigerant flow to the second branch pipe 32 is further increased, thereby further improving the problem of uneven flow distribution caused by refrigerant dynamic pressure, improving the flow distribution effect of the flow distribution assembly 100, and improving the efficiency of the heat exchanger assembly 200. At the same time, since the first sub-pipe 321 and the third sub-pipe 323 are located on opposite sides of the second sub-pipe 322, installation interference between the first sub-pipe 321 and the third sub-pipe 323 can be avoided.

[0095] For example in Figure 1 and Figure 2 In the example shown, the first sub-pipe 321 and the third sub-pipe 323 are respectively located on both sides of the length of the second sub-pipe 322, and on opposite sides of the radial direction of the second sub-pipe 322, thus forming a Z-shaped structure for the second branch pipe 32. Figure 1 and Figure 2 In the example shown, the second sub-tube 322 extends along the axis of the body portion 1, but the present invention is not limited thereto, and the second sub-tube 322 may also extend along the radial direction of the body portion 1.

[0096] In some embodiments of this utility model, such as Figure 4As shown, the multiple sub-tubes also include a third sub-tube 323. One end of the third sub-tube 323 is connected to the end of the second sub-tube 322 that is away from the first sub-tube 321. The third sub-tube 323 is perpendicular to the second sub-tube 322. The first sub-tube 321 and the third sub-tube 323 are located on the same side of the second sub-tube 322.

[0097] Understandably, by adding the third sub-pipe 323, the resistance to refrigerant flow to the second branch pipe 32 is further increased, thereby further improving the problem of uneven flow distribution caused by refrigerant dynamic pressure, improving the flow distribution effect of the flow distribution assembly 100, and improving the efficiency of the heat exchanger assembly 200. At the same time, since the first sub-pipe 321 and the third sub-pipe 323 are located on the same side of the second sub-pipe 322, they can share the space on the same side of the second sub-pipe 322 for installation, making the structure more compact and reducing the volume of the heat exchanger assembly 200.

[0098] For example in Figure 4 In the example shown, the first sub-pipe 321 and the third sub-pipe 323 are respectively located on both sides of the second sub-pipe 322 along its length and on the same side of the second sub-pipe 322 in its radial direction, thus forming a U-shaped structure for the second branch pipe 32. Figure 4 In the example shown, the second sub-tube 322 extends in the radial direction of the body portion 1, but the present invention is not limited thereto, and the second sub-tube 322 may also extend in the axial direction of the body portion 1.

[0099] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, a second arc-shaped section 325 is provided between the second sub-pipe 322 and the third sub-pipe 323. Understandably, the arc design helps maintain uniform and stable airflow, reducing turbulence and eddies caused by sudden changes in direction, and improving the efficiency of the air conditioning system 300. The airflow is smoother as it passes through the second arc-shaped section 325, which helps reduce noise caused by airflow turbulence. Furthermore, the second arc-shaped section 325 reduces the impact and wear of the refrigerant on the inner wall of the pipes, extending the service life of the inlet and outlet pipes 34. The second arc-shaped section 325 makes the installation of the second sub-pipe 322 and the third sub-pipe 323 more flexible, allowing for easier adaptation to space constraints and layout requirements. The second arc-shaped section 325 helps prevent the accumulation of dust and debris inside the pipes, reducing maintenance problems caused by blockages, and also helps reduce damage to system components caused by impacts and vibrations.

[0100] In some embodiments of this utility model, such as Figure 1As shown, the main body 1 includes a manifold 102, which includes a first manifold 15 and a second manifold 16. A first port 11 and a first connecting hole 13 are provided on the first manifold 15, and a second port 12 and a second connecting hole 14 are provided on the second manifold 16. The first manifold 15 and the second manifold 16 are integral parts, and the flow-blocking component 2 is provided inside the first manifold 15 or the second manifold 16. The first manifold 15 and the second manifold 16 are integrally processed. During the processing, the flow-blocking component 2 can be directly fixed inside the first manifold 15 or the second manifold 16 without the need for alignment and connection of multiple pipe sections. This simplifies the assembly process of the diversion assembly 100, reduces the difficulty of disassembling and assembling the diversion assembly 100, improves the assembly efficiency and maintenance efficiency of the diversion assembly 100, and also reduces potential leakage points, thereby reducing the risk of leakage of the diversion assembly 100. Furthermore, the manifold 102 is a flute-shaped pipe, which is vertically or inclined, and the multiple first connecting holes 13 face the horizontal direction, so as to facilitate the refrigerant to be distributed through the manifold 102 to the multiple first connecting holes 13.

[0101] In some embodiments of this utility model, such as Figure 1 As shown, the main body 1 includes a manifold 102, a first manifold 15, and a second manifold 16. A first port 11 and a first connecting hole 13 are provided on the first manifold 15, and a second port 12 and a second connecting hole 14 are provided on the second manifold 16. The first manifold 15 and the second manifold 16 are separate components, and a flow-blocking component 2 is connected between the first manifold 15 and the second manifold 16. The first manifold 15 and the second manifold 16 are manufactured separately. The first manifold 15 and the second manifold 16 are arranged along the length of the diversion assembly 100 and connected to each other. The flow-blocking component 2 is connected between the first manifold 15 and the second manifold 16. This allows the first manifold 15 and the second manifold 16 to be manufactured separately, reducing manufacturing difficulty and improving production efficiency. When assembling the diversion assembly 100, the first manifold 15, the flow-blocking component 2, and the second manifold 16 are connected sequentially, facilitating the assembly of the diversion assembly 100. Furthermore, when the first manifold 15, the flow-blocking component 2, or the second manifold 16 is damaged or needs to be replaced, only the corresponding component needs to be replaced, rather than the entire flow-splitting assembly 100, thereby reducing the maintenance cost of the flow-splitting assembly 100.

[0102] In some embodiments of this utility model, such as Figures 1-4As shown, a first branch pipe 31 is connected to the first connecting hole 13, and a second branch pipe 32 is connected to the second connecting hole 14. The first branch pipe 31 is connected to the outer peripheral wall of the first manifold 15, and the second branch pipe 32 is connected to the outer peripheral wall of the second manifold 16. Among the multiple sub-pipes, the sub-pipe directly connected to the second connecting hole 14 is the first sub-pipe 321. In the projection plane perpendicular to the axis of the second manifold 16, the angle between the first sub-pipe 321 and at least one first branch pipe 31 is A°, and satisfies: 0°≤A°≤180°. For example, A° can be 0°, 50°, 90° or 180°, etc.

[0103] It should be noted that there are multiple first branch pipes 31, and at least one of the multiple first branch pipes 31 extends in a straight line. The angle A° between the first sub-pipe 321 and at least one first branch pipe 31 refers to the angle A° between the first sub-pipe 321 and the straight-extending first branch pipe 31.

[0104] Since 0°≤A°≤180°, the end of the first branch pipe 31 facing away from the first connecting port and the end of the second branch pipe 32 facing away from the second connecting hole 14 have the same orientation. When A° is greater than 180°, the end of the second branch pipe 32 facing away from the second connecting hole 14 will be bent too much, which may cause problems such as breakage. Therefore, 0°≤A°≤180° can avoid breakage caused by excessive bending angle between multiple sub-pipes.

[0105] In some embodiments of this utility model, such as Figures 1-4 As shown, a first branch pipe 31 is connected to the first connecting hole 13, and a second branch pipe 32 is connected to the second connecting hole 14. The first branch pipe 31 is connected to the outer peripheral wall of the first manifold 15, and the second branch pipe 32 is connected to the outer peripheral wall of the second manifold 16. In a projection plane perpendicular to the axis of the second manifold 16, the first branch pipe 31 and the second branch pipe 32 are spaced apart. It can be understood that, in a projection plane perpendicular to the axis of the second manifold 16, the first branch pipe 31 and the second branch pipe 32 are spaced apart, which helps to avoid installation interference between the first branch pipe 31 and the second branch pipe 32.

[0106] On the other hand, since both the end of the first branch pipe 31 away from the first connecting port and the end of the second branch pipe 32 away from the second connecting hole 14 are connected to heat exchange tubes 41, and the heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4, and by separating the first branch pipe 31 and the second branch pipe 32 in the projection plane perpendicular to the axis of the body part 1, the first branch pipe 31 and the second branch pipe 32 can be connected to heat exchange tubes 41 in different rows, thereby realizing the counter-current arrangement of the refrigerant and the heat exchange airflow. The counter-current arrangement can maintain a large temperature difference between the refrigerant and the heat exchange airflow on the heat exchange tubes 41, thereby maximizing the heat exchange efficiency. This can effectively improve the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and improve energy efficiency.

[0107] For example, refer to Figure 9 As shown, the heat exchanger body 4 has a plurality of heat exchange tubes 41, which form at least one first flow path 42 and at least one second flow path 43. The heat exchange tubes 41 on the first flow path 42 near the first branch pipe 31 and the heat exchange tubes 41 on the second flow path 43 near the second branch pipe 32 are located on opposite sides of the thickness direction of the heat exchanger body 4. The two sides of the thickness direction of the heat exchanger body 4 are the first side and the second side, respectively. The heat exchange tubes 41 on the first flow path 42 near the first connecting hole 13 are located on the first side of the thickness direction of the heat exchanger body 4, and the heat exchange tubes 41 on the second flow path 43 near the second connecting hole 14 are located on the second side of the thickness direction of the heat exchanger body 4. The refrigerant in the main body 1 enters the heat exchange tube 41 located on the first side of the first flow path 42 through the first connecting hole 13 and the first branch pipe 31, and flows from the first side to the second side. It then flows into the heat exchange tube 41 located on the first side of the second flow path 43 through components such as the manifold 5. The refrigerant flows from the first side to the second side in the second flow path 43, and flows out of the heat exchanger body 4 through the second branch pipe 32 and the second connecting hole 14 from the heat exchange tube 41 located on the second side of the second flow path 43, so as to enter the main body 1.

[0108] Therefore, it can be seen that along the thickness direction of the heat exchanger body 4, the refrigerant flows from the first side to the second side within the heat exchanger body 4. This facilitates the setting of the position and orientation of the heat exchanger assembly 200 and the control of the flow direction of the airflow exchanging heat with the heat exchanger assembly 200, ensuring that the flow direction of the airflow exchanging heat with the heat exchanger assembly 200 is opposite to the flow direction of the refrigerant within the heat exchanger body 4, thus facilitating a counter-flow arrangement of the refrigerant and the heat exchange airflow. This counter-flow arrangement allows the refrigerant and the heat exchange airflow to maintain a large temperature difference on the heat exchange tube 41, thereby maximizing the heat exchange efficiency. This can effectively improve the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and increase energy efficiency.

[0109] In some embodiments of this utility model, such as Figures 1-4 As shown, a first branch pipe 31 is connected to the first connecting hole 13, and a second branch pipe 32 is connected to the second connecting hole 14. The first branch pipe 31 is connected to the outer peripheral wall of the first manifold 15, and the second branch pipe 32 is connected to the outer peripheral wall of the second manifold 16. The ends of the first branch pipe 31 and the second branch pipe 32 facing away from the second connecting hole 14 have the same orientation. It can be understood that both the ends of the first branch pipe 31 and the second branch pipe 32 facing away from the second connecting hole 14 need to be connected to the heat exchange tube 41. The inlets (inlets or outlets) of the heat exchange tubes 41 on the same side of the length direction of the heat exchanger body 4 have the same orientation. By having the ends of the first branch pipe 31 and the second branch pipe 32 facing away from the second connecting hole 14 have the same orientation, it is convenient to install and connect the ends of the first branch pipe 31 and the second branch pipe 32 facing away from the second connecting hole 14 to the heat exchange tube 41.

[0110] In some embodiments of this utility model, the inner diameter of the second branch pipe 32 is less than or equal to the inner diameter of the first branch pipe 31. When the refrigerant enters the second manifold 16 from the second port 12, the flow-blocking component 2 is activated, and part of the refrigerant flows from the second port 12 to the second connecting hole 14, while the other part of the refrigerant flows to the first connecting hole 13 after passing through the flow-blocking component 2.

[0111] Understandably, by making the inner diameter of the second branch pipe 32 smaller than that of the first branch pipe 31, the flow resistance of the refrigerant flowing into the body 1 from the second port 12 will increase. This allows more refrigerant to continue flowing towards the first connecting hole 13 after passing through the flow-blocking component 2, thus meeting the flow requirements of the first connecting hole 13. This better achieves the flow-dividing effect, improves the uneven flow distribution caused by refrigerant dynamic pressure, and further enhances the flow-dividing effect of the flow-dividing component 100. When the flow-dividing component 100 is applied to the heat exchanger assembly 200 and the air conditioning system 300, it can improve the heat exchange efficiency of the heat exchanger assembly 200, improve the cooling or heating performance of the air conditioning system 300, and improve energy efficiency.

[0112] In some embodiments of this utility model, such as Figure 1 As shown, the flow distribution assembly 100 also includes an inlet / outlet pipe 34, one end of which is connected to the second port 12. The inlet / outlet pipe 34 is connected to the main body 1 and communicates with the second port 12. The inlet / outlet pipe 34 facilitates indirect connection between the main body 1 and components such as the throttling device 64 in the air conditioning system 300, which can relatively reduce the difficulty of connecting the flow distribution assembly 100 with other components, help reduce the probability of refrigerant leakage, and ensure the normal operation of the air conditioning system 300.

[0113] For example, such as Figure 11As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser. The refrigerant flows into the heat exchanger assembly 200 from the first port 11. At this time, the flow-blocking component 2 is not open. The refrigerant enters the heat exchange tube 41 from the first connecting hole 13. After passing through the intermediate component such as the flow-collecting component 5, the refrigerant re-enters the heat exchange tube 41. Then it enters the body part 1 from the second connecting hole 14 and finally flows out of the heat exchanger assembly 200 from the inlet and outlet pipes 34.

[0114] like Figure 12 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. Refrigerant flows into the heat exchanger assembly 200 from the inlet and outlet pipes 34. The flow-blocking component 2 is open, and part of the refrigerant enters the heat exchange tube 41 from the second connecting hole 14. Another part of the refrigerant passes through the flow-blocking component 2 in the body part 1 and then enters the heat exchange tube 41 through the first connecting hole 13. The refrigerant in the heat exchange tube 41 flows out of the heat exchanger assembly 200 after being collected by intermediate components such as the flow-collecting component 5.

[0115] It should be noted that the welding connection between the inlet / outlet pipe 34 and the main body 1 can ensure the connection strength between the inlet / outlet pipe 34 and the main body 1, improve the structural strength of the diversion assembly 100, and ensure the reliability and stability of the diversion assembly 100. Furthermore, during the welding process, the weld metal fills the gap between the main body 1 and the inlet / outlet pipe 34, forming a dense connection layer, which can effectively prevent refrigerant leakage.

[0116] In some embodiments of this utility model, such as Figure 1 , Figures 5-8 As shown, the inlet and outlet pipes 34 are U-shaped or V-shaped. When the refrigerant enters through the inlet and outlet pipes 34, the U-shaped or V-shaped inlet and outlet pipes 34 can accelerate the refrigerant under the action of centrifugal force, thereby increasing the refrigerant flow power within the main body 1 and preventing the refrigerant from accumulating at the inlet and outlet pipes 34. This can improve the refrigerant flow distribution within the flow distribution assembly 100. When the flow distribution assembly 100 is applied to the heat exchanger assembly 200, it can improve the heat exchange efficiency of the heat exchanger assembly 200 and improve energy efficiency.

[0117] In some embodiments of this utility model, such as Figure 6 and Figure 8 As shown, a first branch pipe 31 is connected to the first connecting hole 13. The first branch pipe 31 is connected to the outer peripheral wall of the first manifold 15. In the projection plane perpendicular to the axis of the second manifold 16, the inlet pipe 34 has at least one radial extension 341 extending in the radial direction of the second manifold 16. The angle between the radial extension 341 closest to the second port 12 and the first branch pipe 31 is B and satisfies: 15°≤B°≤225°. For example, B° can be 15°, 45°, 50° or 225°, etc.

[0118] It is understandable that by having the radial extension 341 closest to the second port 12 and the first branch pipe 31 at an angle of B that satisfies: 15°≤B°≤225°, there is sufficient spacing between the first branch pipe 31 and the inlet / outlet pipe 34 in the circumferential direction of the main body 1, thereby avoiding installation interference between the first branch pipe 31 and the inlet / outlet pipe 34.

[0119] Furthermore, such as Figure 6 and Figure 8 As shown, the inlet / outlet pipe 34 extends in a direction away from the first branch pipe 31, thereby further avoiding installation interference between the inlet / outlet pipe 34 and the first branch pipe 31.

[0120] In some embodiments of this utility model, such as Figure 5 and Figure 7 As shown, a second branch pipe 32 is connected to the second connecting hole 14. The second branch pipe 32 is connected to the outer peripheral wall of the second manifold 16. The angle between the tangent of the axis of the end of the inlet / outlet pipe 34 connected to the second port 12 and the axis of the second manifold 16 is C, and satisfies: 0°≤C°≤135°. For example, C° can be 0°, 40°, 50°, or 135°. It should be noted that the second port 12 can be located on the peripheral wall of the main body 1 or on the end face of the main body 1 in the axial direction, thereby meeting different connection requirements. The 0°≤C°≤135° setting facilitates the installation of the inlet / outlet pipe 34.

[0121] In some embodiments of this utility model, such as Figure 1 As shown, the second port 12 is formed by opening one end of the main body 1 on the side of the flow-blocking component 2 away from the first port 11 along its length. The second port 12 is provided at one end of the main body 1 along its length, which is simple in structure, convenient in processing and manufacturing, and conducive to improving production efficiency and reducing costs. In addition, the second port 12 is located at the end of the main body 1 along its length, which is also convenient for installation and assembly, thereby improving assembly efficiency.

[0122] In some embodiments of this invention, the second port 12 is located on the peripheral wall of the main body 1. The refrigerant enters through the second port 12 located on the peripheral wall of the main body 1, which can form strong vortices, secondary flows, and turbulence within the main body 1, making the refrigerant temperature more uniform and thus improving the convective heat transfer coefficient.

[0123] In some embodiments of this utility model, such as Figure 1As shown, the first port 11 is formed by opening one end of the main body 1 on the side of the flow-blocking component 2 away from the second port 12 in the length direction. The first port 11 is set at one end of the main body 1 in the length direction. The structure is simple and easy to process and manufacture. It is beneficial to improve the production and processing efficiency and reduce the cost. Moreover, the first port 11 is set at the end of the main body 1 in the length direction, which is also convenient for installation and assembly, thereby improving the assembly efficiency.

[0124] In some embodiments of this invention, the first port 11 is located on the peripheral wall of the main body 1. The refrigerant enters from the first port 11 located on the peripheral wall of the main body 1, which can form strong vortices, secondary flows and turbulence within the main body 1, making the refrigerant temperature more uniform and improving the convective heat transfer coefficient.

[0125] In some embodiments of this utility model, such as Figure 1 As shown, the flow distribution assembly 100 also includes an intake pipe 33, one end of which is connected to the first port 11. The intake pipe 33 is connected to the main body 1 and communicates with the first port 11. The arrangement of the intake pipe 33 facilitates indirect connection between the main body 1 and components such as the four-way valve in the air conditioning system 300, which can relatively reduce the difficulty of connecting the flow distribution assembly 100 with other components, help reduce the probability of refrigerant leakage, and ensure the normal operation of the air conditioning system 300.

[0126] For example, such as Figure 11 As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser. The refrigerant flows into the heat exchanger assembly 200 from the inlet pipe 33. At this time, the flow-blocking component 2 is not open. The refrigerant enters the heat exchange tube 41 from the first connecting hole 13. After passing through the intermediate component such as the flow-collecting component 5, the refrigerant enters the heat exchange tube 41 again. Then it enters the body part 1 from the second connecting hole 14 and finally flows out of the heat exchanger assembly 200 from the second port 12.

[0127] like Figure 12 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. Refrigerant flows into the heat exchanger assembly 200 from the second port 12. The flow-blocking component 2 is open, and part of the refrigerant enters the heat exchange tube 41 through the second connecting hole 14. The other part of the refrigerant passes through the flow-blocking component 2 in the body part 1 and then enters the heat exchange tube 41 through the first connecting hole 13. The refrigerant in the heat exchange tube 41 flows out of the heat exchanger assembly 200 after being collected by intermediate components such as the flow-collecting component 5. At this time, the intake pipe 33 is set to an open circuit state and has a liquid storage function. Part of the liquid refrigerant in the body part 1 will be stored in the intake pipe 33 and will not participate in the circulation of the air conditioning system 300, thus regulating the refrigerant flow rate in the air conditioning system 300. The length and diameter of the intake pipe 33 can be adjusted according to the specific operating requirements of the air conditioning system 300, thereby regulating the refrigerant flow rate in the air conditioning system 300 according to the specific situation.

[0128] It should be noted that the intake pipe 33 is welded to the main body 1, which can ensure the connection strength between the intake pipe 33 and the main body 1, improve the structural strength of the diversion assembly 100, and ensure the reliability and stability of the diversion assembly 100. In addition, during the welding process, the weld metal fills the gap between the main body 1 and the intake pipe 33, forming a dense connection layer, which can effectively prevent refrigerant leakage.

[0129] In some embodiments of this utility model, such as Figure 1 As shown, the intake pipe 33 is U-shaped. When the refrigerant enters through the intake pipe 33, the U-shape of the intake pipe 33 allows the refrigerant to accelerate under the action of centrifugal force, thereby increasing the flow power of the refrigerant within the body 1 and preventing the refrigerant from accumulating at the intake pipe 33. This can improve the flow distribution of the refrigerant within the distribution assembly 100. When the distribution assembly 100 is applied to the heat exchanger assembly 200, it can improve the heat exchange efficiency of the heat exchanger assembly 200 and increase energy efficiency.

[0130] In some embodiments of this utility model, the inner diameter of the first manifold 15 is less than or equal to the inner diameter of the second manifold 16. When the refrigerant enters the second manifold 16 from the second port 12, the flow-blocking component 2 is activated, and part of the refrigerant flows from the second port 12 to the second connecting hole 14, while another part of the refrigerant flows from the second manifold 16 through the flow-blocking component 2 into the first manifold 15.

[0131] By increasing the inner diameter of the second manifold 16, the initial flow velocity of the refrigerant entering the distribution assembly 100 can be reduced, decreasing the dynamic head while maintaining a higher static head. As some refrigerant flows upward, the static pressure gradually decreases, allowing the inner diameter of the first manifold 15 to be smaller. This increases the refrigerant flow velocity and dynamic head, enabling more refrigerant to pass through the flow-blocking component 2 and enter the first manifold 15. This further improves the refrigerant flow distribution within the distribution assembly 100, achieving a better distribution effect and ensuring that the refrigerant is more evenly distributed to the first connecting hole 13 and the second connecting hole 14. When the distribution assembly 100 is applied to the heat exchanger assembly 200, it can improve the heat exchange efficiency and energy efficiency of the heat exchanger assembly 200.

[0132] Furthermore, making the inner diameter of the first manifold 15 equal to the inner diameter of the second manifold 16 can effectively reduce the difficulty of production and processing, which is conducive to improving the production efficiency of the diverter assembly 100 and reducing costs.

[0133] In some embodiments of this utility model, such as Figure 1As shown, the first connecting hole 13 can be one or multiple holes spaced apart along the length of the first manifold 15. Providing a single first connecting hole 13 reduces the processing difficulty of the flow distribution assembly 100, thereby improving its production efficiency and reducing costs. By providing multiple first connecting holes 13 on the first manifold 15, refrigerant entering the main body 1 can flow out through these holes. When the flow distribution assembly 100 is applied to the heat exchanger assembly 200 and the air conditioning system 300, the refrigerant enters multiple heat exchange tubes 41 in the heat exchanger assembly 200 through the multiple first connecting holes 13, forming multiple flow channels. This improves the heat exchange efficiency of the heat exchanger assembly 200, enhances the cooling or heating performance of the air conditioning system 300, and increases energy efficiency.

[0134] refer to Figure 1 As shown, there are two first connecting holes 13. Of course, there can also be three, four, five or six first connecting holes 13.

[0135] In some embodiments of this utility model, such as Figure 1 As shown, the second connecting hole 14 can be one or multiple holes spaced apart along the length of the second manifold 16. Providing a single second connecting hole 14 reduces the processing difficulty of the flow distribution assembly 100, thereby improving its production efficiency and reducing costs. Multiple second connecting holes 14 on the second manifold 16 allow refrigerant to flow into or out of the main body 1. When the flow distribution assembly 100 is applied to the heat exchanger assembly 200 and the air conditioning system 300, the multiple second connecting holes 14 connect with multiple heat exchange tubes 41 in the heat exchanger assembly 200. Refrigerant can enter the multiple heat exchange tubes 41 in the heat exchanger assembly 200 through the multiple second connecting holes 14, or enter the flow distribution assembly 100 from the heat exchanger assembly 200 through the multiple second connecting holes 14, forming multiple flow channels. This improves the heat exchange efficiency of the heat exchanger assembly 200, enhances the cooling or heating performance of the air conditioning system 300, and improves energy efficiency.

[0136] Specifically, the second connecting hole 14 can be one, two, three, four, five, or six, etc.

[0137] In some embodiments of this utility model, the flow-blocking component 2 is a one-way valve, a solenoid valve, or a baffle. Depending on the specific operational requirements of the flow-diverting assembly 100, a one-way valve, a solenoid valve, or a baffle can be selected as the flow-blocking component 2. This method is simple in structure, easy to implement, and low in cost, and can meet the requirement of allowing only the refrigerant within the main body 1 to flow from the second port 12 to the first port 11.

[0138] In some embodiments of this utility model, such as Figure 13As shown, the main body 1 includes a connecting pipe 101 and a distributor 71. A flow-blocking component 2 is disposed on the connecting pipe. A second port 12 and a second connecting hole 14 are connected to the connecting pipe. At least one of the second port 12 and the second connecting hole 14 is connected to one end of the connecting pipe. The distributor 71 has a main interface 711 and a plurality of distribution holes 712. The main interface 711 is connected to the other end of the connecting pipe. At least some of the distribution holes 712 are first connecting holes 13. A first branch pipe 31 is connected to the distributor 71 through the first connecting hole 13. A second branch pipe 32 is connected to the outer peripheral wall of the connecting pipe.

[0139] In some embodiments of this utility model, the connecting pipe 101 is arranged vertically or inclined, the flow-blocking component 2 is arranged vertically or inclined inside the connecting pipe 101, the distributor 71 forms a flow-dividing cavity, the main interface 711 and a plurality of first connecting holes 13 are respectively located on opposite sides of the distributor 71, the plurality of first connecting holes 13 are all connected to the flow-dividing cavity, the plurality of first connecting holes 13 face upward or obliquely upward, the main interface 711 is connected to the flow-dividing cavity and faces the plurality of first connecting holes 13, and the refrigerant flowing in from the main interface 711 is easily diverted to the plurality of first connecting holes 13.

[0140] The distributor 71 is used to distribute gas when the flow splitting assembly 100 is used as a gas pipe, and to distribute liquid when the flow splitting assembly 100 is used as a liquid pipe, so as to achieve uniform flow distribution of multiple first branch pipes 31 connected to the distributor 71, thereby ensuring the consistency of the operating conditions of multiple first branch pipes 31 and improving heat exchange stability.

[0141] When the diversion assembly 100 is used in the heat exchanger assembly 200 and the air conditioning system 300, the heat exchanger assembly 200 includes a heat exchanger body 4 and a manifold assembly 5. The heat exchanger body 4 has multiple heat exchange tubes 41, which serve as refrigerant flow channels. The manifold assembly 5 is located on one side of the heat exchanger body 4 and communicates with the heat exchange tubes 41. A third port 51 is formed on the manifold assembly 5. The diversion assembly 100 is located on the side of the heat exchanger body 4 away from the manifold assembly 5, or the diversion assembly 100 and the manifold assembly 5 are located on the same side of the heat exchanger body 4. The diversion assembly 100 communicates with the heat exchange tubes 41, and the refrigerant is adapted to flow from one of the diversion assembly 100 and the manifold assembly 5 to the other.

[0142] When the heat exchanger assembly 200 is used as a condenser, the refrigerant flows into the heat exchanger assembly 200 from the first port 11, and then flows into the heat exchange tube 41 or heat exchange channel of the heat exchanger assembly 200 from the first connecting hole 13, and then flows out of the heat exchanger assembly 200 from the second connecting hole 14 and the second port 12 in sequence. The distributor 71 is used to split the gaseous refrigerant, and the flow-blocking component 2 is shut off.

[0143] like Figure 11As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser. The refrigerant is cooled and condensed inside the heat exchanger assembly 200. The refrigerant flows into the heat exchanger assembly 200 from the first port 11. At this time, the flow-blocking component 2 is not open. The refrigerant enters the heat exchange tube 41 through the first connecting hole 13 from the first branch pipe 31 directly connected to the first connecting hole 13. The refrigerant also enters the distributor 71 through the first connecting hole 13 and flows to the multiple first branch pipes 31 connected to the distributor 71 before entering the heat exchange tube 41. The third port 51 is closed. After being collected by the flow-collecting component 5, the refrigerant re-enters the heat exchange tube 41, then enters the connecting pipe 101 from the second connecting hole 14, and finally flows out of the heat exchanger assembly 200 from the second port 12. The refrigerant enters the heat exchange tube 41 through the first connecting hole 13, and after being collected by the manifold 5, it re-enters the heat exchange tube 41. This can further reduce the temperature of the refrigerant and increase its subcooling, thereby forming a subcooling tube design for the condenser and better enhancing the heat exchange efficiency of the heat exchanger assembly 200.

[0144] When the heat exchanger assembly 200 functions as an evaporator, refrigerant flows into the heat exchanger assembly 200 from the second port 12, and then flows out of the heat exchanger assembly 200 through the first connecting hole 13 and the second connecting hole 14 into the heat exchange tube 41 or heat exchange channel. The distributor 71 is used to distribute the liquid refrigerant, the flow-blocking component 2 is open, and the first port 11 is closed. In this embodiment, the first port 11 is closed by a valve in the air conditioner, for example, by a five-way valve 636.

[0145] like Figure 12 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. The refrigerant evaporates and absorbs heat in the heat exchanger assembly 200. The refrigerant flows into the heat exchanger assembly 200 from the second port 12. At this time, the flow-blocking component 2 is open, and part of the refrigerant enters the heat exchange tube 41 from the second connecting hole 14. Another part of the refrigerant passes through the flow-blocking component 2 in the connecting pipe 101, then enters the heat exchange tube 41 through the first connecting hole 13 from the first branch pipe 31 directly connected to the first connecting hole 13. The refrigerant also enters the distributor 71 through the first connecting hole 13 and flows to multiple first branch pipes 31 connected to the distributor 71 before entering the heat exchange tube 41. The third port 51 is open, and the refrigerant in the heat exchange tube 41 flows out of the heat exchanger assembly 200 through the third port 51 after being collected by the flow-collecting component 5. Through the cooperation of the flow-dividing component 100 and the heat exchange tube 41, a multi-path heat exchange pattern can be formed, thereby improving the heat exchange efficiency of the heat exchanger assembly 200.

[0146] Furthermore, in heating mode, the refrigerant needs to pass through a subcooling pipe when entering the conventional outdoor heat exchanger, resulting in pressure loss. However, in this application, by setting a flow-diverting assembly 100 with a flow-blocking component 2, the heat exchanger assembly 200 can form a different flow path in heating mode than in cooling mode. In heating mode, the refrigerant does not need to pass through a subcooling pipe when entering the heat exchanger assembly 200, thus avoiding significant pressure loss.

[0147] In the air conditioning system 300, the heat exchanger assembly 200 serves as the outdoor heat exchanger. During cooling and heating modes, the heat exchanger assembly 200 functions as both the condenser and evaporator, respectively. In these modes, the refrigerant undergoes boiling evaporation and cooling condensation processes within the heat exchanger assembly 200. By incorporating a flow-diverting assembly 100 with flow-blocking components 2, given a fixed area and volume of the heat exchanger assembly 200, different flow paths can be created for the refrigerant, resulting in different optimal flow path designs for the heat exchange during the evaporation and condensation processes within the heat exchanger assembly 200.

[0148] Furthermore, the distributor 71 of this application only plays a distribution role in cooling mode and heating mode without converging, so that the refrigerant is distributed to each distributor at the main interface 711 and then directly enters the first branch pipe 31, without secondary mixing between branches, thereby avoiding backflow and interference, ensuring the consistency of each branch, and improving the distribution stability and heat exchange efficiency in cooling mode and heating mode.

[0149] In some embodiments of this utility model, there are multiple first connecting holes 13, each distribution hole 712 is connected to a first branch pipe 31, and the first port 11 is located on the connecting pipe 101 between the distributor 71 and the flow blocking component 2.

[0150] Understandably, when refrigerant flows into the distribution assembly 100 from the first port 11, because the flow-blocking component 2 is not conductive, the refrigerant enters the distributor 71 from the main interface 711 through the first connecting hole 13, and flows into the corresponding first branch pipe 31 through the multiple distribution holes 712 of the distributor 71, thereby achieving uniform flow distribution. Simultaneously, when refrigerant flows into the distribution assembly 100 from the second port 12, because the flow-blocking component 2 is conductive, part of the refrigerant flows out from the second connecting hole 14, while the other part passes through the flow-blocking component 2 in the connecting pipe 101, enters the distributor 71 from the main interface 711 through the first connecting hole 13, and flows into the corresponding first branch pipe 31 through the multiple distribution holes 712 of the distributor 71, thereby achieving uniform flow distribution.

[0151] Thus, this configuration ensures that the refrigerant, whether entering the distribution assembly 100 from the first port 11 or the second port 12, converges to the first connecting hole 13, then flows into the distributor 71 through the first connecting hole 13 and the main interface 711, and is then distributed at equal pressure to each distribution hole 712. This effectively avoids the formation of bypasses and stagnation chambers that bypass the distributor 71, reduces energy loss, and improves the heat exchange efficiency of the heat exchanger assembly 200 using this distribution assembly 100.

[0152] In some embodiments of this utility model, there are multiple first connecting holes 13 and N distribution holes 712. N-1 distribution holes 712 are respectively connected to a first branch pipe 31, and the remaining distribution hole 712 forms a first port 11.

[0153] Therefore, when the refrigerant flows into the distribution assembly 100 from the first port 11, all the refrigerant flows into the distributor 71. Since the flow-blocking component 2 is not conductive, the refrigerant flows from the distributor 71 through the other distribution holes 712 to the corresponding first branch pipes 31, thereby achieving uniform flow distribution. Furthermore, by integrating the distribution assembly 100 with the distributor 71 through the first port 11, the overall compactness of the distribution assembly 100 is improved, which is conducive to miniaturization and reduces the space occupied by the distribution assembly 100 in the heat exchanger assembly 200. When the refrigerant enters the distribution assembly 100 from the second port 12 and reaches the first connecting hole 13 through the flow-blocking component 2, it is also evenly distributed to the other distribution holes 712 through the main interface 711, which ensures both compact arrangement and uniform supply to each first branch pipe 31, so that the distribution assembly 100 is suitable for miniaturized application scenarios.

[0154] In addition, when the refrigerant flows into the distribution assembly 100 from the first port 11, it forms the first port 11 through the other distribution hole 712. After entering from the first port 11, the refrigerant is directly distributed at the same pressure in the distributor 71 and is evenly distributed by the other distribution holes 712. The flow path of the refrigerant is short and the additional pressure drop is small, which improves the flow efficiency.

[0155] The following is for reference. Figures 9-12 A heat exchanger assembly 200 according to an embodiment of the present invention is described.

[0156] like Figure 1 and Figures 9-12 As shown, the heat exchanger assembly 200 according to an embodiment of the present utility model includes: a heat exchanger body 4, a flow collection assembly 5, and the aforementioned flow distribution assembly 100.

[0157] Specifically, refer to Figure 1 and Figure 9The heat exchanger body 4 has multiple heat exchange tubes 41, which form at least one first flow path 42 and at least one second flow path 43. A flow collector assembly 5 is disposed on one side of the heat exchanger body 4 and is connected to one end of the first flow path 42 and one end of the second flow path 43, respectively. The flow collector assembly 5 has a third port 51. A first branch pipe 31 connects to the other end of the first flow path 42, and a second branch pipe 32 connects to the other end of the second flow path 43. A first connecting hole 13 connects to the end of at least one first flow path 42 away from the flow collector assembly 5, and a second connecting hole 14 connects to the end of at least one second flow path 43 away from the flow collector assembly 5.

[0158] It is understandable that the manifold 5 has the function of collecting and distributing refrigerant, and the refrigerant is suitable to flow from one of the distributor 100 and the manifold 5 to the other.

[0159] For example, when the heat exchanger assembly 200 is applied to the air conditioning system 300, such as Figure 11 As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser. Refrigerant flows into the heat exchanger assembly 200 from the first port 11. At this time, the flow-blocking component 2 is not conductive, and the refrigerant enters the heat exchange tube 41 of the first flow path 42 from the first connecting hole 13. The third port 51 is set to an open circuit state. After being collected by the flow-collecting component 5, the refrigerant enters the heat exchange tube 41 of the second flow path 43 from the first flow path 42, then enters the main body 1 from the second connecting hole 14, and finally flows out of the heat exchanger assembly 200 from the second port 12. The refrigerant entering the heat exchange tube 41 from the first connecting hole 13 and then re-entering the heat exchange tube 41 after being collected by the flow-collecting component 5 can further reduce the temperature of the refrigerant and increase its subcooling, thus forming a subcooling tube design for the condenser and better enhancing the heat exchange efficiency of the heat exchanger assembly 200.

[0160] like Figure 12 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. The refrigerant evaporates and absorbs heat in the heat exchanger assembly 200. The refrigerant flows into the heat exchanger assembly 200 from the second port 12. At this time, the flow-blocking component 2 is open, and part of the refrigerant enters the heat exchange tube 41 of the second flow path 43 from the second connecting hole 14. Another part of the refrigerant passes through the flow-blocking component 2 within the body part 1, and then enters the heat exchange tube 41 of the first flow path 42 through the first connecting hole 13. At this time, the third port 51 is open, and the refrigerant in multiple flow paths flows out of the heat exchanger assembly 200 through the third port 51 after being collected by the flow-collecting component 5. Through the cooperation of the flow-dividing component 100 and the heat exchange tube 41, a multi-flow heat exchange pattern can be formed, thereby improving the heat exchange efficiency of the heat exchanger assembly 200.

[0161] Furthermore, in heating mode, the refrigerant needs to pass through a subcooling pipe when entering the conventional outdoor heat exchanger, resulting in pressure loss. However, in this application, by setting a flow-diverting assembly 100 with a flow-blocking component 2, the heat exchanger assembly 200 can form a different flow path in heating mode than in cooling mode. In heating mode, the refrigerant does not need to pass through a subcooling pipe when entering the heat exchanger assembly 200, thus avoiding significant pressure loss.

[0162] In the air conditioning system 300, the heat exchanger assembly 200 serves as the outdoor heat exchanger. During cooling and heating modes, the heat exchanger assembly 200 functions as both the condenser and evaporator, respectively. In these modes, the refrigerant undergoes boiling evaporation and cooling condensation processes within the heat exchanger assembly 200. By incorporating a flow-diverting assembly 100 with flow-blocking components 2 and a flow-collecting assembly 5, given a fixed area and volume of the heat exchanger assembly 200, different flow paths can be created for the refrigerant, resulting in different optimal flow path designs for the heat exchange during the evaporation and condensation processes within the heat exchanger assembly 200.

[0163] According to the heat exchanger assembly 200 of this utility model embodiment, by setting the above-mentioned flow-dividing assembly 100, along the length direction of the main body 1, the first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2, the second port 12 and the second connecting hole 14 are located on the same side of the flow-blocking component 2, the first port 11 and the second port 12 are located on opposite sides of the flow-blocking component 2, the flow-blocking component 2 only allows refrigerant to flow from the second port 12 side to the first port 11 side, and at least one first branch pipe 31 is connected to the first connecting hole 13, the first branch pipe 31 is connected to the main body 1 and to the first... The connecting hole 13 is connected, and at least one second branch pipe 32 is connected to the second connecting hole 14. The second branch pipe 32 is connected to the main body 1 and communicates with the second connecting hole 14. It can realize the automatic switching of different flow paths of refrigerant in heat exchanger assembly 200 in different modes of air conditioning system 300. The second branch pipe 32 has a bend 326, thereby improving the problem of uneven flow distribution caused by refrigerant dynamic pressure, improving the flow distribution effect of flow distribution assembly 100, thereby improving the heat exchange efficiency of heat exchanger assembly 200, improving the cooling or heating performance of air conditioning system 300, and improving energy efficiency.

[0164] In some embodiments of this utility model, when the heat exchanger assembly is used as an evaporator, the refrigerant flows into the heat exchanger assembly from the second port 12, and flows into the heat exchange tube 41 of the heat exchanger assembly from the first connecting hole 13 and the second connecting hole 14, and then flows out of the heat exchanger assembly from the third port 51. The flow-blocking component 2 is open, and the first port 11 is closed.

[0165] When the heat exchanger assembly functions as a condenser, refrigerant flows into the heat exchanger assembly from the first port 11, and then flows into the heat exchange tube 41 of the heat exchanger assembly from the first connecting hole 13, and subsequently flows out of the heat exchanger assembly from the second connecting hole 14 and the second port 12. Both the flow-blocking component 2 and the third port 51 are blocked. In this embodiment, the third port 51 is blocked by a valve in the air conditioner, for example, by a five-way valve 636.

[0166] In some embodiments of this utility model, such as Figure 9 As shown, the heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4. Both the first flow path 42 and the second flow path 43 include multiple rows of heat exchange tubes 41. The heat exchange tubes 41 of the first flow path 42 connected to the first connecting hole 13 and the heat exchange tubes 41 of the second flow path 43 connected to the second connecting hole 14 are located on opposite sides of the thickness direction of the heat exchanger body 4 or in different rows. This allows the refrigerant to flow in the same direction along the thickness direction of the heat exchanger body 4 within the heat exchange tubes 41, facilitating the setting of the position and orientation of the heat exchanger assembly 200 and controlling the flow direction of the airflow exchanging heat with the heat exchanger assembly 200, thus facilitating the counter-current arrangement of the refrigerant and the heat exchange airflow. This maintains a large temperature difference between the refrigerant and the heat exchange airflow on the heat exchange tubes 41, thereby maximizing the heat exchange efficiency of the heat exchange tubes 41. This is beneficial for improving the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it helps to improve the performance and energy efficiency of the air conditioning system 300.

[0167] refer to Figure 9 As shown, multiple heat exchange tubes 41 form three first flow paths 42 and one second flow path 43. Of course, the number of first flow paths 42 formed by multiple heat exchange tubes 41 can also be one, two, four, five or six, etc., and the number of second flow paths 43 formed by multiple heat exchange tubes 41 can also be two, three, four, five or six, etc.

[0168] When the refrigerant enters the main body 1 from the first port 11, the flow-blocking component 2 is not open, and the refrigerant can only enter the heat exchange tube 41 from the first connecting hole 13, then return to the main body 1 from the heat exchange tube 41 through the second connecting hole 14, and finally flow out of the heat exchanger assembly 200 from the second port 12. The heat exchange tube 41 on the first flow path 42 near the first connecting hole 13 and the heat exchange tube 41 on the second flow path 43 near the second connecting hole 14 are located on opposite sides of the thickness direction of the heat exchanger body 4. This can be understood as connecting the first connecting hole 13 and the second connecting hole 14 to the two sides of the heat exchanger body 4 respectively along the thickness direction of the heat exchanger body 4.

[0169] For example, refer to Figure 9As shown, assuming the two sides of the heat exchanger body 4 in the thickness direction are the first side and the second side, the heat exchange tube 41 on the first flow path 42 near the first connecting hole 13 is located on the first side in the thickness direction of the heat exchanger body 4, and the heat exchange tube 41 on the second flow path 43 near the second connecting hole 14 is located on the second side in the thickness direction of the heat exchanger body 4. The refrigerant in the body part 1 enters the heat exchange tube 41 on the first side of the first flow path 42 through the first connecting hole 13, and flows from the first side to the second side. It then flows into the heat exchange tube 41 on the first side of the second flow path 43 through components such as the manifold 5. The refrigerant flows from the first side to the second side in the second flow path 43, and flows out of the heat exchanger body 4 through the second connecting hole 14 from the heat exchange tube 41 on the second side of the second flow path 43 to enter the body part 1.

[0170] Therefore, it can be seen that along the thickness direction of the heat exchanger body 4, the refrigerant flows from the first side to the second side within the heat exchanger body 4. This facilitates the setting of the position and orientation of the heat exchanger assembly 200 and the control of the flow direction of the airflow exchanging heat with the heat exchanger assembly 200, ensuring that the flow direction of the airflow exchanging heat with the heat exchanger assembly 200 is opposite to the flow direction of the refrigerant within the heat exchanger body 4, thus facilitating a counter-flow arrangement of the refrigerant and the heat exchange airflow. This counter-flow arrangement allows the refrigerant and the heat exchange airflow to maintain a large temperature difference on the heat exchange tube 41, thereby maximizing the heat exchange efficiency. This can effectively improve the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and increase energy efficiency.

[0171] In some embodiments of this utility model, such as Figure 9 As shown, the heat exchange tubes 41 connected to the first connecting hole 13 on the first flow path 42 are located in a row on the leeward side of the heat exchanger body 4, and the heat exchange tubes 41 connected to the second connecting hole 14 on the second flow path 43 are located in a row on the windward side of the heat exchanger body 4. It can be understood that the refrigerant in the body part 1 enters the heat exchange tubes 41 on the leeward side of the first flow path 42 through the first connecting hole 13, and then flows out of the heat exchanger body 4 through the second connecting hole 14 from the heat exchange tubes 41 on the windward side of the second flow path 43 to enter the body part 1.

[0172] This ensures that the refrigerant flows from the leeward side to the windward side along the thickness direction of the heat exchanger body 4, achieving a counter-flow arrangement between the refrigerant and the heat exchange airflow. This counter-flow arrangement allows the refrigerant and the heat exchange airflow to maintain a large temperature difference on the heat exchange tube 41, thereby maximizing heat exchange efficiency. This effectively improves the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and increase energy efficiency.

[0173] In some embodiments of this utility model, such as Figure 9As shown, the heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4. The first flow path 42 includes a row of windward heat exchange tubes 45 located on the windward side of the heat exchanger body 4 and a row of leeward heat exchange tubes 44 located on the leeward side of the heat exchanger body 4. When the heat exchanger assembly is used as a condenser and as an evaporator, the refrigerant flowing into the first flow path 42 first flows through the leeward heat exchange tubes 44 and then flows through the windward heat exchange tubes 45.

[0174] Understandably, the refrigerant in the main body 1 enters the leeward side heat exchange tube 44 of the first flow path 42 through the first connecting hole 13, and flows from the leeward side heat exchange tube 44 to the windward side heat exchange tube 45. This ensures that the refrigerant in the first flow path 42 flows from the leeward side to the windward side along the thickness direction of the heat exchanger body 4, thus achieving a counter-current arrangement of the refrigerant and the heat exchange airflow. This maintains a large temperature difference between the refrigerant and the heat exchange airflow on the heat exchange tube 41, thereby maximizing the heat exchange efficiency. This can effectively improve the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and improve energy efficiency.

[0175] In some embodiments of this utility model, such as Figure 9 As shown, the heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4. The second flow path 43 includes a row of windward heat exchange tubes 45 located on the windward side of the heat exchanger body 4 and a row of leeward heat exchange tubes 44 located on the leeward side of the heat exchanger body 4. When the heat exchanger assembly is used as an evaporator, the refrigerant flowing into the second flow path 43 first flows through the windward heat exchange tubes 45 and then flows through the leeward heat exchange tubes 44. When the heat exchanger assembly is used as a condenser, the refrigerant flowing into the second flow path 43 first flows through the leeward heat exchange tubes 44 and then flows through the windward heat exchange tubes 45.

[0176] The refrigerant flowing out of the first flow path 42 flows into the leeward side heat exchange tube 44 of the second flow path 43. The refrigerant flows from the leeward side heat exchange tube 44 to the windward side heat exchange tube 45 in the second flow path 43, and flows out of the heat exchanger body 4 through the second connecting hole 14 from the windward side heat exchange tube 45 of the second flow path 43 to enter the body part 1.

[0177] This ensures that the refrigerant in the second flow path 43 flows from the leeward side to the windward side along the thickness direction of the heat exchanger body 4, achieving a counter-flow arrangement between the refrigerant and the heat exchange airflow. This maintains a large temperature difference between the refrigerant and the heat exchange airflow on the heat exchange tube 41, thereby maximizing heat exchange efficiency. This effectively improves the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and increase energy efficiency.

[0178] In some embodiments, the refrigerant in the body 1 enters the leeward heat exchange tube 44 of the first flow path 42 through the first connecting hole 13, and flows from the leeward heat exchange tube 44 to the windward heat exchange tube 45. Then, the refrigerant flows from the first flow path 42 into the leeward heat exchange tube 44 of the second flow path 43 through components such as the manifold 5. The refrigerant flows from the leeward heat exchange tube 44 to the windward heat exchange tube 45 in the second flow path 43, and flows out of the heat exchanger body 4 through the second connecting hole 14 from the windward heat exchange tube 45 of the second flow path 43 to enter the body 1.

[0179] In some embodiments of this utility model, such as Figure 11 and Figure 12 As shown, the flow collector assembly 5 and the flow divider assembly 100 are located on the same side along the length of the heat exchanger body 4. The positions of the flow collector assembly 5 and the flow divider assembly 100 can be selected based on the number of rows of heat exchange tubes 41 arranged along the thickness direction of the heat exchanger body 4 and the specific arrangement of the first flow path 42 and the second flow path 43, making the connection between the flow collector assembly 5 and the flow divider assembly 100 and the heat exchanger body 4 simpler and more convenient. Specifically, as... Figure 10 As shown in the example, the flow collector 5 and the flow divider 100 are located on the same side of the length of the heat exchanger body 4.

[0180] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, there are multiple first connecting holes 13. When the heat exchanger assembly 200 functions as an evaporator and when it functions as a condenser, the multiple first connecting holes 13 are used to distribute the refrigerant. This improves the refrigerant flow distribution within the distribution assembly 100, achieving a better flow path distribution effect. When the distribution assembly 100 is applied to the heat exchanger assembly 200, it ensures that the refrigerant can be more evenly distributed into different flow paths of the heat exchanger assembly 200, thereby improving the heat exchange efficiency and energy efficiency of the heat exchanger assembly 200. Furthermore, the multiple first connecting holes 13 are located above or diagonally above the flow-blocking component 2, and the multiple first connecting holes 13 face horizontally, upwards, or diagonally upwards, thus facilitating the distribution of refrigerant to the multiple first connecting holes 13.

[0181] In some embodiments of this invention, the first flow path 42 is located above the second flow path 43; and / or the airflow or average velocity flowing through the first flow path 42 is greater than the airflow or average velocity flowing through the second flow path 43. Thus, when the heat exchanger assembly 200 functions as a condenser, the refrigerant first passes through the first flow path 42 and then through the second flow path 43. Because the refrigerant flowing through the first flow path 42 has a higher temperature and a greater airflow or average velocity, the heat exchange efficiency of the first flow path 42 can be improved, thereby improving the heat exchange efficiency of the heat exchanger assembly 200 when it functions as a condenser, and thus improving energy efficiency.

[0182] The following is for reference. Figure 11 and Figure 12 An air conditioning system 300 according to an embodiment of the present utility model is described.

[0183] like Figure 11 and Figure 12 As shown, the air conditioning system 300 according to an embodiment of the present utility model includes: a compressor 61, a reversing assembly 63, an indoor heat exchanger 62, and the aforementioned heat exchanger assembly 200.

[0184] Specifically, such as Figure 11 and Figure 12 As shown, the compressor 61 has an exhaust port 611 and a return port 612. One end of the indoor heat exchanger 62 is connected to the second port 12. The reversing assembly 63 has a first port 631, a second port 632, a third port 633, a fourth port 634, and a fifth port 635. The first port 631 is connected to the exhaust port 611, the third port 633 is connected to the return port 612, the second port 632 is connected to the other end of the indoor heat exchanger 62, the fourth port 634 is connected to the third port 12, and the fifth port 635 is connected to the first port 12. When 11 is connected, the commutator 63 has a first switching state and a second switching state; when the commutator 63 is in the first switching state, the first port 631 is connected to the fifth port 635, the second port 632 is connected to the third port 633, and the fourth port 634 is cut off to close the third port 51 (so that the third port 51 is cut off); when the commutator 63 is in the second switching state, the first port 631 is connected to the second port 632, the third port 633 and the fourth port 634 are connected, and the fifth port 635 is cut off to cut off the first port 11.

[0185] It is understandable that during the specific operation of the air conditioning system 300, such as Figure 11 As shown in the example, when the air conditioning system 300 is in cooling mode, the commutator 63 is in the first switching state, and the first port 631 of the commutator 63 is connected to the fifth port 635, and the second port 632 is connected to the third port 633.

[0186] Therefore, compressor 61 compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant enters the reversing assembly 63 through the compressor 61's exhaust port 611 and the first port 631, and then flows to the heat exchanger assembly 200 through the fifth port 635. The heat exchanger assembly 200 can exchange heat with the external environment and dissipate heat through condensation. The refrigerant flows within the heat exchanger assembly 200 and releases heat to the external environment, thus changing from a gaseous state to a liquid state. The high-pressure liquid refrigerant flowing out of the heat exchanger assembly 200 then flows to the throttling device 64, which reduces the refrigerant pressure, allowing the low-pressure liquid refrigerant to flow into the indoor heat exchanger 62. The indoor heat exchanger 62 absorbs heat. The refrigerant is heated and vaporized within the indoor heat exchanger 62, changing from a liquid state to a gaseous state, thereby carrying away the heat from the airflow flowing over the surface of the indoor heat exchanger 62. The low-temperature airflow is then delivered into the room by the indoor unit of the air conditioner to achieve the purpose of cooling. Meanwhile, the low-pressure gaseous refrigerant flows to the second port 632 of the reversing component 63, and from the third port 633 to the return port 612 to return to the compressor 61 for compression again, thereby forming a refrigerant cycle and achieving the cooling effect of the air conditioning system 300.

[0187] In this process, refrigerant flows into the heat exchanger assembly 200 from the first port 11. At this time, the flow-blocking component 2 is not conductive. The refrigerant enters the heat exchange tube 41 of the first flow path 42 from the first connecting hole 13, then enters the heat exchange tube 41 of the second flow path 43 from the first flow path 42, then enters the body part 1 from the second connecting hole 14, and finally flows out of the heat exchanger assembly 200 from the second port 12. The refrigerant first enters the heat exchange tube 41 of the first flow path 42 from the first connecting hole 13, and after being collected, it enters the heat exchange tube 41 of the second flow path 43. This can further reduce the temperature of the refrigerant and increase its subcooling, thereby forming a subcooling tube design for the condenser and better enhancing the heat exchange efficiency of the heat exchanger assembly 200.

[0188] Similarly, such as Figure 12 As shown in the example, when the air conditioning system 300 is in heating mode, the reversing component 63 is in the second switching state, and the first port 631 of the reversing component 63 is connected to the second port 632, and the third port 633 and the fourth port 634 are connected.

[0189] Therefore, compressor 61 compresses the refrigerant into a high-temperature, high-pressure gas. The high-pressure gaseous refrigerant enters the reversing assembly 63 through the compressor 61's exhaust port 611 and the first port 631, and then flows to the indoor heat exchanger 62 through the second port 632. The indoor heat exchanger 62 can exchange heat with the airflow flowing over its surface. The airflow absorbs heat, and the refrigerant condenses and dissipates heat. The high-temperature airflow is sent into the room by the indoor unit of the air conditioner to achieve the purpose of heating. The refrigerant flows in the indoor heat exchanger 62 and releases heat into the indoor environment, thus changing from a gaseous state to a liquid state. The high-pressure liquid refrigerant flowing out of the indoor heat exchanger 62 then flows to the throttling device 64. The throttling device 64 can throttle the flow, reduce the pressure of the refrigerant, and allow the low-pressure liquid refrigerant to flow into the heat exchanger assembly 200. The heat exchanger assembly 200 can absorb heat. The refrigerant absorbs heat and vaporizes in the heat exchanger assembly 200, changing from a liquid state to a gaseous state, thereby carrying away the heat flowing through the outdoor environment. The low-pressure gaseous refrigerant flows to the fourth port 634 of the reversing assembly 63, and from the third port 633 to the return port 612 to return to the compressor 61 for compression again, thus forming a refrigerant cycle and achieving the heating effect of the air conditioning system 300.

[0190] In this process, refrigerant flows into the heat exchanger assembly 200 from the second port 12. At this time, the flow-blocking component 2 is open, and part of the refrigerant enters the heat exchange tube 41 of the second flow path 43 from the second connecting hole 14. Another part of the refrigerant passes through the flow-blocking component 2 in the body part 1, and then enters the heat exchange tube 41 of the first flow path 42 through the first connecting hole 13. The refrigerant from multiple flow paths is collected and flows out of the heat exchanger assembly 200 and flows to the fourth port 634 of the reversing component 63. By cooperating with the flow-diverting component 100 and the heat exchange tube 41 body, a multi-flow-path heat exchange pattern can be formed, thereby improving the heat exchange efficiency of the heat exchanger assembly 200.

[0191] By setting up the reversing assembly 63, the flow path of the air conditioning system 300 can be automatically switched without changing any components. This allows the refrigerant to automatically switch its flow direction within the reversing assembly 63, thereby enabling the air conditioning system 300 to automatically switch between cooling and heating modes to meet the needs of various environmental conditions. Furthermore, no manual adjustment is required, greatly improving the convenience and efficiency of operation, thus enhancing the reliability and efficiency of the air conditioning system 300 and ultimately improving user comfort.

[0192] By adding a flow-blocking component 2 to the flow distribution assembly 100, the flow-blocking component 2 automatically opens, closes, or cuts off the flow based on the pressure difference of the refrigerant on both sides. This allows for automatic flow guidance of the refrigerant by the flow-blocking component 2, changing the flow direction of the refrigerant. In different modes of the air conditioning system 300, automatic switching of the refrigerant's flow path within the heat exchanger assembly 200 can be achieved, improving the heat exchange efficiency of the heat exchanger assembly 200, enhancing the cooling or heating performance of the air conditioning system 300, and improving energy efficiency. Furthermore, no other control structure is required, making it less susceptible to power failures, and the structure is simple, easy to implement, and low in cost.

[0193] Furthermore, the first connecting hole 13 is connected to one end of at least one first flow path 42, and the second connecting hole 14 is connected to one end of at least one second flow path 43. The heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4. Both the first flow path 42 and the second flow path 43 include multiple rows of heat exchange tubes 41. The heat exchange tubes 41 of the first flow path 42 connected to the first connecting hole 13 and the heat exchange tubes 41 of the second flow path 43 connected to the second connecting hole 14 are located on opposite sides of the thickness direction of the heat exchanger body 4 or in different rows.

[0194] It is understandable that when the heat exchanger assembly 200 functions as a condenser, the refrigerant flows in the same direction as the thickness of the heat exchanger body 4. This facilitates the setting of the position and orientation of the heat exchanger assembly 200 and the control of the flow direction of the airflow exchanging heat with the heat exchanger assembly 200, ensuring that the flow direction of the airflow exchanging heat with the heat exchanger assembly 200 is opposite to the flow direction of the refrigerant within the heat exchanger body 4. This facilitates a counter-current arrangement of the refrigerant and the heat exchange airflow. This counter-current arrangement allows the refrigerant and the heat exchange airflow to maintain a large temperature difference on the heat exchange tube 41, thereby maximizing heat exchange efficiency. This effectively improves the heat exchange efficiency of the heat exchanger assembly 200. When the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the cooling or heating performance of the air conditioning system 300 and increase energy efficiency.

[0195] According to the embodiment of the present invention, the air conditioning system 300 includes a heat exchanger assembly 200 and a flow distribution assembly 100. Along the length of the main body 1, the first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2, and the second port 12 and the second connecting hole 14 are also located on the same side of the flow-blocking component 2. The first port 11 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows refrigerant to flow from the second port 12 side to the first port 11 side. At least one first branch pipe 31 is connected to the first connecting hole 13. The first branch pipe 31 is connected to the main body 1. The first connecting hole 13 is connected to the second connecting hole 14, and at least one second branch pipe 32 is connected to the second connecting hole 14. The second branch pipe 32 is connected to the main body 1 and to the second connecting hole 14. It can realize the automatic switching of different flow paths of refrigerant in heat exchanger assembly 200 in different modes of air conditioning system 300. The second branch pipe 32 has a bend 326, thereby improving the problem of uneven flow distribution caused by refrigerant dynamic pressure, improving the flow distribution effect of flow distribution assembly 100, thereby improving the heat exchange efficiency of heat exchanger assembly 200, improving the cooling or heating performance of air conditioning system 300, and improving energy efficiency.

[0196] In some embodiments, such as Figure 11 and Figure 12 As shown, the reversing assembly 63 includes a five-way valve 636 and a pilot valve 637. The five-way valve 636 has a first port 631, a second port 632, a third port 633, a fourth port 634, and a fifth port 635 disposed on the five-way valve 636. The pilot valve 637 is used to control the connection between the first port 631 and the fifth port 635 and the connection between the second port 632 and the third port 633, or to control the connection between the first port 631 and the second port 632 and the connection between the third port 633 and the fourth port 634.

Along the length of the main body 1, the first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2, and the second port 12 and the second connecting hole 14 are also located on the same side of the flow-blocking component 2. The first port 11 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows refrigerant to flow from the second port 12 side to the first port 11 side. At least one first branch pipe 31 is connected to the first connecting hole 13. The system is connected to the main body 1 and communicates with the first communicating hole 13. At least one second branch pipe 32 is connected to the second communicating hole 14.

It can realize the automatic switching of different flow paths of refrigerant in heat exchanger assembly 200 in different modes of air conditioning system 300. The second branch pipe 32 has a bend 326, thereby improving the problem of uneven flow distribution caused by refrigerant dynamic pressure, improving the flow distribution effect of flow distribution assembly 100, thereby improving the heat exchange efficiency of heat exchanger assembly 200, improving the cooling or heating performance of air conditioning system 300, and improving energy efficiency.
