Description

Technical Field

[0001] This utility model relates to the field of air handling equipment technology, and in particular to a flow distribution component, a heat exchanger component, an air conditioning system, and an air conditioner. Background Technology

[0002] In related technologies, the heat exchanger flow path design of an air conditioning system directly affects its performance. During cooling and heating processes, the outdoor heat exchanger acts as both a condenser and an evaporator, respectively. During these processes, the refrigerant undergoes evaporation (absorbing heat) and cooling (condensing heat) within the outdoor heat exchanger. Given a fixed area and volume of the outdoor heat exchanger, its optimal heat exchange flow path differs depending on whether it functions as a condenser or an evaporator. Current air conditioning systems use a single flow path for the outdoor heat exchanger, which cannot be adaptively adjusted according to the system's operating mode, thus affecting the heat exchange efficiency of the outdoor heat exchanger and the overall performance of the air conditioning system. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a flow-diverting component that can change the flow path of the medium, enabling automatic switching of different flow paths of the medium within the heat exchanger assembly under different modes of the air conditioning system, thereby improving the heat exchange efficiency of the heat exchanger assembly and the performance of the air conditioning system.

[0004] This utility model also proposes a heat exchanger assembly, which includes the above-mentioned flow splitter assembly.

[0005] This utility model also proposes an air conditioning system, which includes the heat exchanger assembly described above.

[0006] This utility model also proposes an air conditioner, which includes the above-mentioned air conditioning system.

[0007] According to an embodiment of the present invention, a diverter assembly includes a main body, which includes a diverter located at one end of the main body. The diverter has a first passage, a second passage, and a third passage. One end of the first passage, one end of the second passage, and one end of the third passage are interconnected. The other end of the second passage is open and forms a second port. The other end of the third passage is open and forms a second connecting hole. The main body also has a first connecting hole. A flow-blocking component is disposed on the main body or in the first passage. The flow-blocking component is connected to the other end of the first passage. The first connecting hole is located in the flow-blocking component. On one side, the second port and the second connecting hole are located on the same side of the flow-blocking component, and the first connecting hole and the second port are located on opposite sides of the flow-blocking component. The flow-blocking component only allows the medium to flow from the second port to the first connecting hole. The resistance of the fluid flowing from the second passage to the first passage is the first resistance, and the resistance of the fluid flowing from the second passage to the third passage is the second resistance, where the second resistance is greater than the first resistance. Alternatively, the flow rate of the fluid flowing from the second passage to the first passage is the first flow rate, and the flow rate of the fluid flowing from the second passage to the third passage is the second flow rate, where the first flow rate is greater than the second flow rate.

[0008] According to an embodiment of the present invention, the flow-diverting assembly includes a flow divider located at one end of the main body. The flow divider has a first passage, a second passage, and a third passage. One end of the first passage, one end of the second passage, and one end of the third passage are interconnected. The other end of the second passage is open to form a second port, and the other end of the third passage is open to form a second connecting hole. The main body also has a first connecting hole. A flow-blocking component is disposed on the main body or in the first passage. The flow-blocking component is connected to the other end of the first passage. The first connecting hole is located on one side of the flow-blocking component. The second port and the second connecting hole are located on the same side of the flow-blocking component. The first connecting hole and the second port are located on opposite sides of the flow-blocking component. The flow-blocking component only allows the medium to flow from the second port to the first connecting hole. The flow-blocking component can automatically open and close or cut off the flow to achieve automatic flow guidance of the medium, thereby changing the flow direction of the medium. The flow divider also enables the medium entering through the second port to be preferentially guided to the main body and participate in heat exchange through the first connecting hole. When used in heat exchanger assemblies and air conditioning systems, the flow distribution component can automatically switch the flow path of the medium within the heat exchanger assembly in different modes of the air conditioning system. This improves the heat exchange efficiency of the heat exchanger assembly, enhances the cooling or heating performance of the air conditioning system, and increases energy efficiency.

[0073] The shunt assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0074] like Figures 1-3 As shown, the main body 1 and the flow-blocking component 2 are according to one embodiment of the present invention.

[0075] The main body 1 includes a distributor 8 located at one end of the main body 1. The distributor 8 has a first passage 81, a second passage 82, and a third passage 83. One end of the first passage 81, one end of the second passage 82, and one end of the third passage 83 are interconnected. The other end of the second passage 82 is open to form a second port 12, and the other end of the third passage 83 is open to form a second connecting hole 14. The main body 1 also has a first connecting hole 13. The distributor 8 can be a three-way distributor, a four-way distributor, a five-way distributor, a six-way distributor, a seven-way distributor, an eight-way distributor, a nine-way distributor, or other distributor elements.

[0076] It is understood that the main body 1 has a main channel, and the second port 12, the first connecting hole 13, and the second connecting hole 14 are all connected to the main channel. A medium flows in the main channel, which may specifically be a refrigerant.

[0077] In some embodiments, the splitter 8 includes a splitter body, in which a first passage 81, a second passage 82 and a third passage 83 are formed. One end of the first passage 81, one end of the second passage 82 and one end of the third passage 83 are interconnected, and the other ends of the first passage 81, the second passage 82 and the third passage 83 are spaced apart or isolated from each other.

[0078] In other embodiments, the distributor 8 includes a distributor body and a refrigerant pipe at least partially inserted into the distributor body. The refrigerant pipe and the distributor body together form a first passage 81, a second passage 82, and a third passage 83, such that one end of the first passage 81, one end of the second passage 82, and one end of the third passage 83 are interconnected, and the other ends of the first passage 81, the second passage 82, and the third passage 83 are spaced apart or isolated from each other. The refrigerant pipe can be any one or more of the following: a piping, a manifold, a heat transfer pipe, an extension pipe 34, a second branch pipe 32, a second manifold 16, and a connecting pipe 101.

[0079] The flow-blocking component 2 is disposed on the main body 1 or in the first passage 81. The flow-blocking component 2 is connected to the other end of the first passage 81. The first connecting hole 13 is located on one 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 connecting hole 13 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows the medium to flow from the second port 12 to the first connecting hole 13.

[0080] The resistance to the fluid flowing from the second passage 82 to the first passage 81 is the first resistance, and the resistance to the fluid flowing from the second passage 82 to the third passage 83 is the second resistance. The second resistance is greater than the first resistance. Therefore, when the medium enters the distributor 8 through the second port 12, the medium first enters the distribution cavity 84, which is interconnected with the first passage 81, the second passage 82, and the third passage 83. Since the second resistance is greater than the first resistance, most of the medium enters the main body 1 through the second passage 82 and along the first passage 81, and flows to the first connecting hole 13 under the unidirectional guidance of the flow-blocking component 2. The remaining small portion of the medium flows to the second connecting hole 14 through the second passage 82 and along the third passage 83.

[0081] Alternatively, the flow rate of fluid from the second passage 82 to the first passage 81 is the first flow rate, and the flow rate of fluid from the second passage 82 to the third passage 83 is the second flow rate, where the first flow rate is greater than the second flow rate. Therefore, when the medium enters the distributor 8 through the second port 12, the medium first enters the distribution cavity 84, which connects the first passage 81, the second passage 82, and the third passage 83. Because the second resistance is greater than the first resistance, most of the medium flows through the second passage 82 and along the first passage 81 into the main body 1, and under the unidirectional guidance of the flow-blocking component 2, flows towards the first connecting hole 13. The remaining small portion of the medium flows through the second passage 82 and along the third passage 83 towards the second connecting hole 14.

[0082] Therefore, the resistance of the fluid flowing from the second passage 82 to the first passage 81 is the first resistance, and the resistance of the fluid flowing from the second passage 82 to the third passage 83 is the second resistance. The second resistance is greater than the first resistance, so that most of the medium entering the distributor 8 from the second passage 82 flows into the first connecting hole 13 through the first passage 81, and a small part of the medium flows into the second connecting hole 14 through the third passage 83. This ensures that the medium entering from the second port 12 is preferentially guided to the main body 1 and participates in heat exchange through the first connecting hole 13, ensuring a stable supply to the branch with the first connecting hole 13. This makes the flow path switching of the distributor 100 in the two modes of cooling / heating more stable, and the heat exchange efficiency and system energy efficiency are higher.

[0083] For example, when the flow distribution 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 flow collector assembly 5. The heat exchanger body 4 has a plurality of heat exchange tubes 41, which serve as channels for the flow of the medium. The flow collector 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 flow collector assembly 5. The flow distribution assembly 100 is located on the side of the heat exchanger body 4 away from the flow collector assembly 5, or the flow distribution assembly 100 and the flow collector assembly 5 are located on the same side of the heat exchanger body 4. The flow distribution assembly 100 communicates with the heat exchange tubes 41, and the medium is adapted to flow from one of the flow distribution assembly 100 and the flow collector assembly 5 to the other.

[0084] like Figure 12As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser. The medium cools and condenses within the heat exchanger assembly 200. The medium flows into the heat exchanger assembly 200, and at this time, the flow-blocking component 2 is not conductive. The medium enters the heat exchange tube 41 through the first connecting hole 13, the third port 51 is closed, and after being collected by the flow-collecting component 5, the medium re-enters the heat exchange tube 41. Then, it enters the main body 1 through the second connecting hole 14, and finally flows out of the heat exchanger assembly 200 through the second port 12. The medium entering the heat exchange tube 41 through the first connecting hole 13 and re-entering it after being collected by the flow-collecting component 5 can further reduce the temperature of the medium 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.

[0085] like Figure 13 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. The medium evaporates and absorbs heat in the heat exchanger assembly 200. The medium flows into the heat exchanger assembly 200 from the second port 12 and first flows into the distributor 8. At this time, the flow-blocking component 2 is open. The resistance of the fluid flowing from the second passage 82 to the first passage 81 is the first resistance, and the resistance of the fluid flowing from the second passage 82 to the third passage 83 is the second resistance. The second resistance is greater than the first resistance, so that most of the medium entering the distributor 8 from the second passage 82 flows into the body part 1 through the first passage 81 and into the first connecting hole 13 through the flow-blocking component 2. Then it enters the heat exchange tube 41 through the first connecting hole 13. A small part of the medium flows into the second connecting hole 14 through the third passage 83 and then into the heat exchange tube 41 through the first connecting hole 13. The third port 51 is open, and the medium in the heat exchange tube 41 flows out of the heat exchanger assembly 200 through the third port 51 after being collected by the collector component 5. By combining the flow splitter 100 with 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.

[0086] Therefore, most of the medium preferentially enters the first connecting hole 13 through the first passage 81, ensuring a stable and continuous supply to the evaporation circuit on one side of the main body 1. A small portion of the medium enters the second connecting hole 14 through the third passage 83, forming a supply branch parallel to the first connecting hole 13, reducing the risk of "gas / liquid starvation". At the same time, by guiding the flow ratio of "large flow through the first passage 81 and small flow through the third passage 83", the pressure pulsation in the distributor 8 and the impact on the flow-blocking component 2 can be weakened, reducing bypass short circuits and secondary mixing, stabilizing the flow and phase distribution on the evaporation side, thereby improving the average evaporation temperature and heat exchange utilization, reducing additional pressure drop and flow-induced noise, and improving the heat exchange efficiency and system energy efficiency under heating conditions.

[0087] Furthermore, in heating mode, the medium needs to pass through a subcooling pipe when entering a 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 medium does not need to pass through a subcooling pipe when entering the heat exchanger assembly 200, thus avoiding significant pressure loss.

[0088] 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 a condenser and an evaporator, respectively. In these modes, the medium 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 medium, resulting in different optimal flow path designs for the heat exchange during the evaporation and condensation processes within the heat exchanger assembly 200.

[0089] This application adds a flow-blocking component 2 to the flow-diverting assembly 100. The flow-blocking component 2 automatically opens, closes, or cuts off the flow based on the pressure difference between the media on both sides, thereby enabling automatic flow guidance of the media and changing the flow direction of the media. When the flow-blocking component 2 is used in the heat exchanger assembly 200 and the air conditioning system 300, it can automatically switch the different flow paths of the media 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, improving the cooling or heating performance of the air conditioning system 300, and improving energy efficiency. Furthermore, no other control structure is required, it is less susceptible to power failures, and the structure is simple, easy to implement, and low in cost.

[0090] According to the present invention, the diverter assembly 100 includes a diverter 8 located at one end of the main body 1. The diverter 8 has a first passage 81, a second passage 82, and a third passage 83. One end of the first passage 81, one end of the second passage 82, and one end of the third passage 83 are interconnected. The other end of the second passage 82 is open to form a second port 12, and the other end of the third passage 83 is open to form a second connecting hole 14. The main body 1 also has a first connecting hole 13. A flow-blocking member 2 is disposed on the main body 1 or in the first passage 81. The flow-blocking member 2 is connected to the first passage. The other end of 81 is connected, with the first connecting hole 13 located on one side of the flow-blocking component 2, and the second port 12 and the second connecting hole 14 located on the same side of the flow-blocking component 2. The first connecting hole 13 and the second port 12 are located on opposite sides of the flow-blocking component 2. The flow-blocking component 2 only allows the medium to flow from the second port 12 to the first connecting hole 13, enabling automatic opening and closing or flow interception of the flow-blocking component 2 to automatically guide the medium, thereby changing the flow direction of the medium. The flow divider 8 ensures that the medium entering through the second port 12 is preferentially guided to the main body 1 and participates in heat exchange through the first connecting hole 13. When the flow-dividing component 100 is used in the heat exchanger assembly 200 and the air conditioning system 300, it can automatically switch the different flow paths of the medium in 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, improving the cooling or heating performance of the air conditioning system 300, and improving energy efficiency. Moreover, no other control structure is required, making the structure simple, easy to implement, and low in cost.

[0091] In some embodiments of this utility model, such as Figures 1-3 As shown, the diverter 8 has a diverter cavity 84, with one end of the first passage 81, one end of the second passage 82, and one end of the third passage 83 all connected to the diverter cavity 84. It can be understood that since the other end of the first passage 81 is connected to the main body 1, the other end of the second passage 82 is open to form a second port 12, and the other end of the third passage 83 is open to form a second connecting hole 14. The diverter cavity 84 enables the connection of the first passage 81, the second passage 82, and the third passage 83, thereby enabling the connection of the main body 1, the second port 12, and the second connecting hole 14.

[0092] Meanwhile, the diversion cavity 84 serves as a common cavity for the first passage 81, the second passage 82, and the third passage 83. The medium entering through the second port 12 is first stabilized and rectified in the diversion cavity 84, and then enters the main body 1 through the first passage 81 according to the predetermined resistance matching relationship. Under the unidirectional conduction of the flow blocking component 2, it flows to the first connecting hole 13. A small amount of medium enters the second connecting hole 14 through the third passage 83 to form a replenishment branch.

[0093] In some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the axes of the first passage 81, the second passage 82, and the third passage 83 extend in a straight line. This arrangement allows the medium entering the distributor 8 from the second port 12 to exit along the first passage 81 and the third passage 83 with fewer bends and lower local resistance, reducing separation and eddy currents within the distributor 8, thereby lowering additional pressure drop and noise. Simultaneously, the straight-line extension of the axes of the first passage 81, the second passage 82, and the third passage 83 allows for a more compact arrangement of the distributor 8, improves welding and sealing reliability, and reduces manufacturing and assembly difficulties.

[0094] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the second passage 82 and the third passage 83 are located on the same side of the distributor 8, while the first passage 81 and the second passage 82 are located on opposite sides of the distributor 8. Therefore, through the positional relationship of the first passage 81, the second passage 82, and the third passage 83, the resistance to fluid flowing from the second passage 82 to the first passage 81 is the first resistance, and the resistance to fluid flowing from the second passage 82 to the third passage 83 is the second resistance, with the second resistance being greater than the first resistance. This ensures that the medium entering the distributor 8 from the second port 12 will preferentially enter the main body 1 via the first passage 81.

[0095] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the openings of the second passage 82 and the third passage 83 face the same side, while the openings of the second passage 82 and the first passage 81 face opposite sides. Therefore, through the positional relationship of the first passage 81, the second passage 82, and the third passage 83, the resistance to fluid flow from the second passage 82 to the first passage 81 is the first resistance, and the resistance to fluid flow from the second passage 82 to the third passage 83 is the second resistance, with the second resistance being greater than the first resistance. This ensures that the medium entering the diverter 8 from the second port 12 will preferentially enter the main body 1 via the first passage 81.

[0096] In some embodiments of this utility model, such as Figure 3 As shown, the axis of the second passage 82 and the axis of the third passage 83 are parallel, while the axis of the first passage 81 and the axis of the second passage 82 do not coincide. Therefore, when the axis of the second passage 82 and the axis of the third passage 83 are parallel, the non-coincidence of the axis of the first passage 81 and the axis of the second passage 82 effectively prevents the medium from flowing entirely into the first passage 81 after entering through the second passage 82, resulting in almost no flow in the third passage 83. This ensures that most of the medium enters the first passage 81, and a small portion enters the third passage 83, achieving more stable distribution in the distributor 8 and improving the heat exchange uniformity and overall energy efficiency of the heat exchanger assembly 200 using this distributor component 100.

[0097] In some embodiments of this utility model, such as Figure 3 As shown, the axis of the first passage 81 is parallel to the axis of the second passage 82, and the axis of the first passage 81 is located between the axes of the second passage 82 and the third passage 83. This arrangement further ensures that the resistance to fluid flow from the second passage 82 to the first passage 81 is the first resistance, and the resistance to fluid flow from the second passage 82 to the third passage 83 is the second resistance, with the second resistance being greater than the first resistance. This ensures that the medium entering the distributor 8 from the second port 12 will preferentially enter the main body 1 via the first passage 81, reducing separation and eddies within the distributor 8, thereby reducing additional pressure drop and noise.

[0098] In some embodiments of this utility model, such as Figure 4 As shown, there are multiple third channels 83, which are spaced apart along the circumferential direction of the second channel 82, and the axis of the first channel 81 and the axis of the second channel 82 coincide.

[0099] It is understandable that, since the second passage 82 and the third passage 83 are located on the same side of the distributor 8, and the first passage 81 and the second passage 82 are located on opposite sides of the distributor 8, the axes of the first passage 81 and the second passage 82 are aligned so that the first passage 81 and the second passage 82 form a straight connection. The flow resistance from the second passage 82 to the first passage 81 is small. Meanwhile, multiple third passages 83 are spaced apart along the circumferential direction of the second passage 82 so that the flow resistance from the second passage 82 to the third passage 83 is large. Thus, the resistance of the fluid flowing from the second passage 82 to the first passage 81 is the first resistance, and the resistance of the fluid flowing from the second passage 82 to the third passage 83 is the second resistance, and the second resistance is greater than the first resistance.

[0100] Meanwhile, since the other end of the third passage 83 is open to form multiple second connecting holes 14, the third passage 83 is multiple, so that there are multiple second connecting holes 14. Each second connecting hole 14 is connected to a second branch pipe 32 connected to the heat exchange tube 41, so that there are multiple heat exchange tubes 41 corresponding to the third passage 83 one by one. Thus, the medium entering the multiple third passages 83 through the second branch pipe 32 is dispersed to the multiple heat exchange tubes 41, achieving uniform supply, reducing "starved gas / starved liquid", improving the two-phase distribution and temperature field, making the heat exchange more uniform, and the energy efficiency and operational stability higher.

[0101] In some embodiments of this utility model, such as Figure 4As shown, the axis of the second passage 82 is parallel to the axis of the third passage 83. It can be understood that when multiple third passages 83 are spaced apart along the circumferential direction of the second passage 82, the parallelism between the axes of the second passage 82 and the third passage 83 reduces the resistance difference between the multiple third passages 83. The medium can be evenly distributed into each third passage 83 according to a predetermined ratio, and enter the corresponding heat exchange tube 41 through the second connecting hole 14 and the second branch pipe 32 respectively, achieving more uniform heat exchange and higher energy efficiency and operational stability.

[0102] In some embodiments of this utility model, such as Figure 5 As shown, the axes of the first passage 81 and the second passage 82 coincide, and the axis of the third passage 83 is perpendicular to the axis of the second passage 82; or the axes of the first passage 81 and the second passage 82 coincide, and the angle between the axis of the third passage 83 and the axis of the second passage 82 is smaller than the angle between the axis of the third passage 83 and the axis of the first passage 81. Therefore, this arrangement reduces the local flow loss from the second passage 82 to the first passage 81, and ensures that a small portion of the medium can flow into the third passage 83 during the flow from the second passage 82 to the first passage 81. This achieves a first resistance for fluid flowing from the second passage 82 to the first passage 81 and a second resistance for fluid flowing from the second passage 82 to the third passage 83, with the second resistance being greater than the first resistance.

[0103] In some embodiments of this utility model, the inner diameter of the second passage 82 is D2, and the inner diameter of the third passage 83 is D3, satisfying: D2 ≥ D3. Therefore, by having the inner diameter of the second passage 82 greater than or equal to the inner diameter of the third passage 83, the connection resistance between the second passage 82 and the third passage 83 is greater, thereby increasing the flow resistance and reducing the flow rate from the second passage 82 into the third passage 83. Furthermore, the smaller inner diameter of the third passage 83 can further increase the flow resistance and reduce the flow rate from the second passage 82 into the third passage 83. Thus, the resistance to fluid flow from the second passage 82 to the first passage 81 is the first resistance, and the resistance to fluid flow from the second passage 82 to the third passage 83 is the second resistance, with the second resistance being greater than the first resistance. For example, as... Figure 1 and Figure 2 As shown, the inner diameter of the second passage 82 is larger than the inner diameter of the third passage 83.

[0104] In some embodiments of this invention, the inner diameter of the first passage 81 is D1, and the inner diameter of the third passage 83 is D3, satisfying that D1 > D3. Therefore, this arrangement increases the flow rate from the second passage 82 into the first passage 81 and decreases the flow rate from the second passage 82 into the third passage 83, thereby achieving a first resistance for fluid flowing from the second passage 82 to the first passage 81 and a second resistance for fluid flowing from the second passage 82 to the third passage 83, with the second resistance being greater than the first resistance.

[0105] In some embodiments of this utility model, the open end of the second passage 82 is connected to an extension pipe 34, and the open end of the third passage 83 is connected to a second branch pipe 32. The inner diameter of the extension pipe 34 is greater than or equal to the inner diameter of the second branch pipe 32. Therefore, by making the inner diameter of the extension pipe 34 greater than or equal to the inner diameter of the second branch pipe 32, the connection resistance between the second passage 82 and the third passage 83 is increased, thereby increasing the flow resistance and reducing the flow rate from the second passage 82 into the third passage 83. Furthermore, the smaller inner diameter of the third passage 83 can further increase the flow resistance and reduce the flow rate from the second passage 82 into the third passage 83. Thus, the resistance to fluid flow from the second passage 82 to the first passage 81 is the first resistance, and the resistance to fluid flow from the second passage 82 to the third passage 83 is the second resistance, and the second resistance is greater than the first resistance. For example, as... Figure 1 and Figure 2 As shown, the inner diameter of the second passage 82 is larger than the inner diameter of the third passage 83.

[0106] In some embodiments of this invention, the open end of the first passage 81 is connected to a second manifold 16 or a connecting pipe, the inner diameter of which is larger than the inner diameter of the second branch pipe 32. This arrangement increases the flow rate from the second passage 82 into the first passage 81 and decreases the flow rate from the second passage 82 into the third passage 83, thereby achieving a first resistance for fluid flowing from the second passage 82 to the first passage 81 and a second resistance for fluid flowing from the second passage 82 to the third passage 83, with the second resistance being greater than the first resistance.

[0107] In some embodiments of this invention, the open end of the first passage 81 is connected to a second manifold 16 or a connecting pipe 101, and the open end of the second passage 82 is connected to an extension pipe 34. The inner diameter of the second manifold 16 or the connecting pipe 101 is greater than or equal to the inner diameter of the extension pipe 34. This arrangement increases the flow rate from the second passage 82 into the first passage 81 and reduces the flow rate from the second passage 82 into the third passage 83, allowing more refrigerant entering through the extension pipe 34 to flow into the second manifold 16 or the connecting pipe 101.

[0108] In some embodiments of this utility model, such as Figures 1-3 and Figure 6 As shown, the second connecting hole 14 is connected to a second branch pipe 32. The minimum cross-sectional inner diameter of the second branch pipe 32 is D0, and it satisfies: D0 ≤ D3. It can be understood that when the inner diameter of the second passage 82 is greater than or equal to the inner diameter of the third passage 83, by further limiting the inner diameter of the second branch pipe 32 to be less than or equal to the inner diameter of the third passage 83, the resistance to fluid flow from the second passage 82 to the first passage 81 can be further increased, thereby reducing the flow rate from the second passage 82 into the third passage 83. For example, as... Figure 1and Figure 2 As shown, the inner diameter of the second passage 82 is equal to the inner diameter of the third passage 83, and the inner diameter of the second branch pipe 32 is smaller than the inner diameter of the third passage 83.

[0109] In some embodiments of this utility model, the inner diameter of the third passage 83 is D3, and satisfies: D3≥3mm. Therefore, this limitation effectively prevents excessive resistance in the flow of medium from the second passage 82 into the distributor 8 to the third passage 83, thus avoiding insufficient flow of medium into the third passage 83 and improving the overall reliability of the distributor assembly 100.

[0110] It should be noted that the inner diameter of the third passage 83 can be 3mm, 4mm, 5mm, 6mm or 7mm, etc.

[0111] In some embodiments of this utility model, such as Figure 1 As shown, the main body 1 also includes a manifold 10, a flow-blocking component 2 disposed on the manifold 10, the manifold 10 including a first manifold 15 and a second manifold 16, a first connecting hole 13 disposed on the first manifold 15, and a flow divider 8 disposed on the second manifold. The first manifold 15 and the second manifold 16 are integral parts, the flow-blocking component 2 is disposed inside the first manifold 15 or the second manifold 16, and the flow divider 8 is disposed at the end of the second manifold away from the flow-blocking component 2; or, the first manifold 15 and the second manifold 16 are separate parts, the flow-blocking component 2 is connected between the first manifold 15 and the second manifold 16, and the flow divider 8 is disposed at the end of the second manifold away from the flow-blocking component 2. Further, the manifold 10 is a flute-shaped pipe, the manifold 10 is vertically or inclined, and the multiple first connecting holes 13 face the horizontal direction, thereby facilitating the refrigerant to flow through the main body 1 to the multiple first connecting holes 13.

[0112] Therefore, the first manifold 15 and the second manifold 16 are integrally manufactured. During the manufacturing process, 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 flow divider assembly 100, reduces the difficulty of disassembling and assembling the flow divider assembly 100, improves the assembly efficiency and maintenance efficiency of the flow divider assembly 100, and also reduces potential leakage points, thereby reducing the risk of leakage of the flow divider assembly 100.

[0113] Alternatively, the first manifold 15 and the second manifold 16 can be manufactured separately. The first manifold 15 and the second manifold 16 are arranged along the length of the flow divider assembly 100 and connected to each other, with the flow-blocking component 2 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 flow divider assembly 100, the first manifold 15, the flow-blocking component 2, and the second manifold 16 are connected sequentially, facilitating assembly. Furthermore, if the first manifold 15, the flow-blocking component 2, or the second manifold 16 is damaged or needs replacement, only the corresponding component needs to be replaced, rather than the entire flow divider assembly 100, thus reducing maintenance costs.

[0114] Meanwhile, during the processing of the diversion component 100, the flow blocking component 2 can be directly fixed on the first collector pipe 15 or the second collector pipe 16, thereby reducing the processing difficulty.

[0115] 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 medium enters the second manifold 16 from the second port 12, the flow-blocking component 2 is activated, and part of the medium flows from the second port 12 to the second connecting hole 14, while another part of the medium flows from the second manifold 16 through the flow-blocking component 2 into the first manifold 15.

[0116] By increasing the inner diameter of the second manifold 16, the initial flow velocity of the medium entering the flow distribution assembly 100 can be reduced, decreasing the dynamic head while maintaining a higher static head. As some of the medium flows upward, the static pressure gradually decreases, allowing the inner diameter of the first manifold 15 to be smaller. This increases the flow velocity of the medium, increases the dynamic head, and allows more medium to pass through the flow-blocking component 2 into the first manifold 15. This improves the flow distribution of the medium within the flow distribution assembly 100, achieving a better flow distribution effect and ensuring that the medium is more evenly distributed to the first connecting hole 13 and the second connecting hole 14. When the flow 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.

[0117] 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.

[0118] In some embodiments, the manifold 10 is welded to the flow-blocking component 2, which ensures the reliability and stability of the connection between the manifold 10 and the flow-blocking component 2, reduces the impact of loose connections on the flow distribution effect, extends the service life of the flow distribution assembly 100, and ensures the normal operation of the heat exchanger assembly 200 when the flow distribution assembly 100 is applied to the heat exchanger assembly 200. Furthermore, because the welded connection is stable and reliable, the connection and maintenance costs of the manifold 10 and the flow-blocking component 2 can be relatively reduced. For example, when the manifold 10 includes a first manifold 15 and a second manifold 16 that are interconnected and separately manufactured, the flow-blocking component 2 can be welded to the first manifold 15 and the second manifold 16 respectively.

[0119] In some embodiments, the manifold 10 and the flow-blocking component 2 are interference-fitted. The manifold 10 has a main flow channel, and the actual size of the flow-blocking component 2 is slightly larger than the actual size of the main flow channel. During assembly, external force is applied to achieve a tight connection between the manifold 10 and the flow-blocking component 2. The interference fit between the manifold 10 and the flow-blocking component 2 can generate huge contact pressure through the elastic deformation between the materials, thereby achieving a high-strength connection between the manifold 10 and the flow-blocking component 2. No additional fasteners are required, which simplifies the structure and reduces costs.

[0120] 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.

[0121] By increasing the inner diameter of the second manifold 16, the initial flow velocity of the medium entering the flow distribution assembly 100 can be reduced, decreasing the dynamic head while maintaining a higher static head. As some of the medium flows upward, the static pressure gradually decreases, allowing the inner diameter of the first manifold 15 to be smaller. This increases the flow velocity of the medium and the dynamic head, enabling more medium to pass through the flow-blocking component 2 and enter the first manifold 15. This further improves the flow distribution of the medium within the flow distribution assembly 100, achieving a better flow distribution effect and ensuring that the medium is more evenly distributed to the first connecting hole 13 and the second connecting hole 14. When the flow 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.

[0122] 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.

[0123] 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. Providing multiple first connecting holes 13 on the first manifold 15 allows the medium entering the first manifold 15 to 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 medium 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.

[0124] 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, etc.

[0125] In some embodiments of this utility model, such as Figure 1 As shown, the main body 1 also has a first port 11, and the end of the first manifold 15 facing away from the flow-blocking component 2 is open to form the first port 11; or, as Figure 7 As shown, the first port 11 is located on the peripheral wall of the first manifold 15; or, as... Figure 7 and Figure 8 As shown, the first manifold 15 includes a manifold body 151 and a first tee pipe 152. The first end of the first tee pipe 152 is connected to the flow-blocking component 2, and the second end of the first tee pipe 152 is connected to the manifold body 151. The first port 11 is located at the third end of the first tee pipe 152, and the manifold body 151 is provided with a first connecting hole 13. Thus, this arrangement allows the first port 11 to be positioned at different locations on the body 1, thereby improving versatility. Simultaneously, when the medium enters the body 1 from the first port 11, the flow-blocking component 2 is not conductive, and the medium 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 medium can only flow from the first port 11 to the first connecting hole 13.

[0126] In some embodiments of this utility model, such as Figure 3 As shown, the end of the second manifold 16 facing away from the flow-blocking component 2 is open to form a second port 12; or, the second port 12 is located on the peripheral wall of the second manifold 16, thereby facilitating the flow of refrigerant between the second manifold 16 and the flow-blocking component 2, shortening the flow path, and effectively reducing local resistance and energy loss.

[0127] In some embodiments of this utility model, such as Figure 1As shown, the flow distribution assembly 100 also includes a flow distribution pipe 72. One end of the flow distribution pipe 72 is connected to the first connecting hole 13, and the other end of the flow distribution pipe 72 is connected to multiple first branch pipes 31. Thus, the medium from the first connecting hole 13 first enters the flow distribution pipe 72 and is then distributed to each of the first branch pipes 31. The flow distribution pipe 72 only undertakes the distribution function and does not undertake the confluence function. After the medium is distributed, there is no secondary mixing between the branches, thereby ensuring the consistency of the flow rate in each of the first branch pipes 31, reducing mixing losses and additional pressure drops, so that the flow distribution assembly 100 can improve the distribution stability and heat exchange efficiency in both cooling and heating conditions.

[0128] Furthermore, such as Figure 1 and Figure 2 As shown, multiple first branch pipes 31 connected to the shunt pipe 72 are located on the same side, so that the shunt pipe 72 concentrates the interfaces on the same side, thereby reducing the number of weld points and sealing surfaces, making the structure more compact and easier to assemble and maintain.

[0129] In some embodiments of this utility model, such as Figure 1 As shown, the first connecting hole 13 is provided on the peripheral wall of the main body 1. Thus, the first connecting hole 13 and the diversion pipe 72 are directly connected on the peripheral wall of the main body 1, and the medium enters the diversion pipe 72 directly from the circumferential side wall of the main body 1, which reduces the number of turns in the flow path of the medium, shortens the flow path, and effectively reduces local resistance and energy loss.

[0130] In some embodiments of this utility model, such as Figure 9 As shown, the main body 1 includes a connecting pipe and a distributor 71. A flow-blocking component 2 is disposed on the connecting pipe 101, and a flow divider 8 is disposed at one end of the connecting pipe 101. 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 101, and at least some of the distribution holes 712 are first connecting holes 13.

[0131] 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.

[0132] Therefore, the refrigerant can flow between the main interface 711 of the distributor 71 and the connecting pipe 101, so that the refrigerant in the main body 1 can be evenly distributed to the first branch pipe 31 connected to the distribution hole 712 via the distributor 71, thereby achieving uniform flow distribution through the distributor 71 and improving the heat exchange stability of the heat exchanger assembly 200 using the flow distribution component 100.

[0133] In addition, the distributor 71 only undertakes distribution and does not merge. After the refrigerant is distributed to each distribution hole 712 at the main interface 711, it directly enters the corresponding first branch pipe 31. There is no secondary mixing and backflow interference between branches, and the mixing loss and additional pressure drop are reduced. Pressure pulsation and flow-induced noise are suppressed. In both cooling and heating modes, the distribution stability and heat exchange efficiency can be improved.

[0134] In some embodiments of this utility model, such as Figure 9 As shown, there are multiple first connecting holes 13, and each distribution hole 712 is connected to a first branch pipe 31. Thus, this arrangement allows the refrigerant entering the distributor 71 to flow through multiple distribution holes 712 to a first branch pipe 31 connected to each distribution hole 712, thereby achieving a more uniform flow distribution.

[0135] In some embodiments of this utility model, such as Figure 9 As shown, the main body 1 also has a first port 11, which is located on the connecting pipe 101 between the distributor 71 and the flow blocking component 2.

[0136] Therefore, when the refrigerant enters the connecting pipe 101 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.

[0137] In some embodiments of this utility model, such as Figure 9 As shown, the main body 1 also has a first port 11, a plurality of first connecting holes 13, and a number of 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 the first port 11.

[0138] 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.

[0139] Meanwhile, 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 medium leakage, and ensure the normal operation of the heat exchanger assembly 200.

[0140] 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.

[0141] Specifically, such as Figure 12 As shown, when the air conditioning system 300 is in cooling mode, the heat exchanger assembly 200 acts as a condenser, and the medium is cooled and condensed in the heat exchanger assembly 200. The medium flows into the heat exchanger assembly 200 from the first port 11. At this time, the flow-blocking component 2 is not open. The medium 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 medium also enters the flow-dividing component 7 through the first connecting hole 13 and flows to multiple first branches connected to the flow-dividing component 7 before entering the heat exchange tube 41. The third port 51 is closed. After being collected by the flow-collecting component 5, the medium re-enters the heat exchange tube 41, 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 medium enters the heat exchange tube 41 through the first connecting hole 13, and after being collected by the collector component 5, it re-enters the heat exchange tube 41. This can further reduce the temperature of the medium 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.

[0142] like Figure 13 As shown, when the air conditioning system 300 is in heating mode, the heat exchanger assembly 200 acts as an evaporator. The medium evaporates and absorbs heat in the heat exchanger assembly 200. The medium 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 medium enters the heat exchange tube 41 from the second connecting hole 14. Another part of the medium passes through the flow-blocking component 2 in the body part 1, and then enters the heat exchange tube 41 from the first branch pipe 31 directly connected to the first connecting hole 13 through the first connecting hole 13. The medium also enters the heat exchange tube 41 through the first connecting hole 13 into the flow-dividing component 7 and flows to multiple first branches connected to the flow-dividing component 7 before entering the heat exchange tube 41. The third port 51 is open, and the medium 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-flow heat exchange pattern can be formed, thereby improving the heat exchange efficiency of the heat exchanger assembly 200.

[0143] In some embodiments of this utility model, the extension tube 34 is a U-shaped tube. When the medium enters through the extension tube 34, the U-shaped extension tube 34 can accelerate the medium under the action of centrifugal force, thereby increasing the power of the medium flowing in the body part 1, preventing the medium from accumulating at the extension tube 34, and improving the flow distribution of the medium in 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.

[0144] 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 in the connecting pipe 101 to flow from the second port 12 to the first connecting hole 13.

[0145] In some embodiments of this utility model, such as Figure 9 As shown, along the length of the connecting pipe 101, the distance between the main interface 711 and the outlet end of the flow-blocking component 2 is 15mm-500mm. It is understandable that if the distance between the first connecting hole 13 connected to the flow-diverting component 7 and the flow-blocking component 2 is too small, the welding / assembly interference between the flow-diverting component 7 and the flow-blocking component 2 on the connecting pipe 101 is likely to overlap, leading to a risk of leakage. Conversely, if the distance between the first connecting hole 13 connected to the flow-diverting component 7 and the flow-blocking component 2 is too large, the refrigerant entering the connecting pipe 101 from the second port 12 will have insufficient flow after passing through the flow-blocking component 2 to reach the first connecting hole 13 near the first port 11. This makes timely replenishment difficult under low-flow conditions, and the excessive size of the flow-diverting component 100 increases space requirements and costs.

[0146] Therefore, by limiting the distance between the first connecting hole 13 connected to the diversion component 7 and the flow blocking component 2 to 15mm-500mm, the size of the diversion component 100 is reduced, while effectively avoiding problems such as assembly interference and unstable supply caused by insufficient pressure difference. This further ensures that the diversion component 100 distributes evenly, switches operating conditions smoothly, and improves energy efficiency and reliability.

[0147] It should be noted that, along the length of the connecting pipe 101, the distance between the first connecting hole 13 connected to the diversion component 7 and the flow blocking component 2 can be 15mm, 20mm, 30mm, 40mm, 50mm, 80mm, 100mm, 150mm, 200mm, 300mm, 400mm or 500mm.

[0148] In some embodiments of this utility model, such as Figure 9As shown, along the length of the connecting pipe 101, the distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 is 15mm-100mm. It is understandable that if the distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 is too small, the welding / assembly interference between the second branch pipe 32 connected to the second connecting hole 14 and the flow-blocking component 2 on the connecting pipe 101 is likely to overlap, leading to a risk of leakage. Conversely, if the distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 is too large, the refrigerant entering the connecting pipe 101 from the second port 12 will flow insufficiently through the second connecting hole 14 to the second branch pipe 32 before flowing to the flow-blocking component 2, making timely replenishment difficult under low-flow conditions.

[0149] Therefore, the distance between the second connecting hole 14 and the inlet end of the flow blocking component 2 is 15mm-100mm. This reduces the size of the flow splitter 100 while effectively avoiding problems such as assembly interference and unstable supply caused by insufficient pressure difference. This further ensures that the flow splitter 100 distributes evenly, switches operating conditions smoothly, and improves energy efficiency and reliability.

[0150] It should be noted that, along the length of the connecting pipe 101, the distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 can be 15mm, 20mm, 30mm, 40mm, 50mm, 80mm or 100mm.

[0151] In some embodiments of this utility model, such as Figure 9 As shown, along the length of the connecting pipe 101, the distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 is less than the distance between the main interface 711 and the outlet end of the flow-blocking component 2.

[0152] It is understandable that the refrigerant entering the connecting pipe 101 from the second port 12 passes sequentially through the second connecting hole 14, the inlet end of the flow-blocking component 2, and the main interface 711, so that the refrigerant flows sequentially into the second branch pipe 32, the flow-blocking component 2, and the distributor 71. The distance between the second connecting hole 14 and the inlet end of the flow-blocking component 2 is less than the distance between the main interface 711 and the outlet end of the flow-blocking component 2, which effectively improves the problem of uneven flow distribution caused by the dynamic pressure of the refrigerant and further improves the flow distribution effect of the flow distribution component 100.

[0153] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, at least one second branch pipe 32 is connected to the second connecting hole 14. It can be understood that the second branch pipe 32 is connected to the connecting pipe 101 and communicates with the second connecting hole 14. The second branch pipe 32 can be used to indirectly connect the connecting pipe 101 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.

[0154] 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.

[0155] In some embodiments, the main body 1 and the flow-blocking component 2 are welded together, which can ensure the reliability and stability of the connection between the main body 1 and the flow-blocking component 2, reduce the impact of loose connection on the flow-diverting effect, extend the service life of the flow-diverting component 100, ensure the normal operation of the heat exchanger component 200 when the flow-diverting component 100 is applied to the heat exchanger component 200, and because the welded connection is stable and reliable, the connection cost and maintenance cost between the main body 1 and the flow-blocking component 2 can be relatively reduced.

[0156] In some embodiments, the body portion 1 and the flow-blocking component 2 are interference-fitted. The body portion 1 has a main flow channel, and the actual size of the flow-blocking component 2 is slightly larger than the actual size of the main flow channel. During assembly, an external force is applied to achieve a tight connection between the body portion 1 and the flow-blocking component 2. The interference fit between the body portion 1 and the flow-blocking component 2 can generate huge contact pressure through the elastic deformation between the materials, thereby achieving a high-strength connection between the body portion 1 and the flow-blocking component 2. No additional fasteners are required, which simplifies the structure and reduces costs.

[0157] The following describes a heat exchanger assembly 200 according to an embodiment of the present invention.

[0158] 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.

[0159] like Figure 12 and Figure 13 As shown, the heat exchanger body 4 has multiple heat exchange tubes 41, which form multiple flow paths. The flow collection assembly 5 is located on one side of the heat exchanger body 4 and is connected to the multiple flow paths. The flow collection assembly 5 has a third port 51. The first connecting hole 13 is connected to the end of at least one flow path away from the flow collection assembly 5, and the second connecting hole 14 is connected to the end of at least one flow path away from the flow collection assembly 5.

[0160] Among them, 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.

[0161] For example, when the heat exchanger assembly 200 is applied to the air conditioning system 300, such as Figure 12As 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, 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 distribute the gaseous refrigerant, and the flow-blocking component 2 is shut off.

[0162] like Figure 12 As 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.

[0163] 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.

[0164] like Figure 13As 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.

[0165] 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.

[0166] 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.

[0167] According to an embodiment of the present invention, the heat exchanger assembly 200 is provided with a flow-diverting component 100. The flow-blocking component 2 allows the medium to flow only from the second port 12 to the first connecting hole 13. This enables the automatic opening and closing or flow blocking of the flow-blocking component 2, thus automatically guiding the medium and changing its flow direction. Furthermore, the flow-diverter 8 ensures that the medium entering through the second port 12 is preferentially guided to the main body 1 and participates in heat exchange through the first connecting hole 13. When the flow-diverting component 100 is used in both the heat exchanger assembly 200 and the air conditioning system 300, it can automatically switch the flow path of the medium 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. Moreover, no other control structures are required, resulting in a simple, easy-to-implement, and low-cost structure.

[0168] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the heat exchange tubes 41 are arranged in multiple rows along the thickness direction of the heat exchanger body 4. The multiple heat exchange tubes 41 form at least one first flow path 42 and at least one second flow path 43. 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 are located in different rows.

[0169] This ensures that the refrigerant flows in a consistent direction along the thickness of the heat exchanger body 4 within the heat exchanger tube 41. 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, allowing for 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 exchanger tube 41, thereby maximizing the heat exchange efficiency of the heat exchanger tube 41. This improves the heat exchange efficiency of the heat exchanger assembly 200, and when the heat exchanger assembly 200 is used in the air conditioning system 300, it helps to improve the performance and energy efficiency of the air conditioning system 300.

[0170] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the heat exchange tubes 41 of the first flow path 42 connected to the first connecting hole 13 are located in a row on the leeward side of the heat exchanger body 4, and the heat exchange tubes 41 of the second flow path 43 connected to the second connecting hole 14 are located in a row on the windward side of the heat exchanger body 4.

[0171] It is understandable that the refrigerant in the main body 1 enters the heat exchange tube 41 located 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 tube 41 located on the windward side of the second flow path 43 to enter the main body 1.

[0172] In this way, when the heat exchanger assembly 200 functions as a condenser, the refrigerant can be ensured to flow from the leeward side to the windward side along the thickness direction of the heat exchanger body 4, thus 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, and when the heat exchanger assembly 200 is applied to the air conditioning system 300, it can improve the performance and energy efficiency of the air conditioning system 300.

[0173] In some embodiments of this utility model, such as Figure 10 and Figure 11As 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 performance and energy efficiency of the air conditioning system 300.

[0175] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the second flow path 43 includes a row of air-facing heat exchange tubes 45 on the air-facing side of the heat exchanger body 4 and a row of leeward heat exchange tubes 44 on the leeward side of the heat exchanger body 4. When the heat exchanger assembly functions as an evaporator, the refrigerant flowing into the second flow path 43 first flows through the air-facing heat exchange tubes 45 and then through the leeward heat exchange tubes 44. When the heat exchanger assembly functions as a condenser, the refrigerant flowing into the second flow path 43 first flows through the leeward heat exchange tubes 44 and then through the air-facing heat exchange tubes 45. The refrigerant flowing out of the first flow path 42 flows into the leeward heat exchange tubes 44 of the second flow path 43. Within the second flow path 43, the refrigerant flows from the leeward heat exchange tubes 44 to the air-facing heat exchange tubes 45, and then flows out of the heat exchanger body 4 through the second connecting hole 14 from the air-facing heat exchange tubes 45 of the second flow path 43 to enter the body section 1.

[0176] This ensures that when the heat exchanger assembly 200 functions as a condenser, 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-current 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, and when applied to the air conditioning system 300, it enhances the performance and energy efficiency of the air conditioning system 300.

[0177] 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.

[0178] In some embodiments of this utility model, such as Figure 10 and Figure 11 As shown, the flow collector 5 and the flow divider 100 are located on the same side along the length of the heat exchanger body 4. The positions of the flow collector 5 and the flow divider 100 can be selected according to 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 5 and the flow divider 100 and the heat exchanger body 4 simpler and more convenient.

[0179] In some embodiments of this utility model, the main body 1 is formed with a first port 11. The first port 11 and the first connecting hole 13 are located on the same side of the flow-blocking component 2. When the heat exchanger assembly 200 is used as an evaporator, the refrigerant flows into the heat exchanger assembly 200 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 200 from the third port 51. The flow-blocking component 2 is open, and the first port 11 is closed.

[0180] When the heat exchanger assembly 200 functions as a condenser, refrigerant flows into the heat exchanger assembly 200 from the first port 11, and then flows into the heat exchange tube 41 of the heat exchanger assembly 200 from the first connecting hole 13, and subsequently flows out of the heat exchanger assembly 200 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.

[0181] When the heat exchanger assembly 200 is applied to the air conditioning system 300, the air conditioning system 300 is in heating mode. 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 in the body part 1, the first port 11 is closed, 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. By cooperating with 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.

[0182] When the heat exchanger assembly 200 is applied to the air conditioning system 300, the air conditioning system 300 is in cooling mode. 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. 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 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 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.

[0183] 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 manifold distribution 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. This allows for different optimal flow path designs for the heat exchange during the evaporation and condensation processes within the heat exchanger assembly 200. This improves the heat exchange efficiency of the heat exchanger assembly 200, thereby enhancing the cooling or heating performance of the air conditioning system 300 and improving energy efficiency.

[0184] In some embodiments of this utility model, such as Figure 5 and Figure 6As 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.

[0185] 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.

[0186] The following describes an air conditioning system 300 according to an embodiment of the present invention.

[0187] An air conditioning system 300 according to an embodiment of the present invention includes: a compressor 61, an indoor heat exchanger 62, the aforementioned heat exchanger assembly 200, and a reversing assembly 63.

[0188] Specifically, such as Figure 12 and Figure 13As 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, and the fourth port 634 connects the end of the first flow path 42 opposite to the first connecting hole 13 and the end of the second flow path 43 opposite to the second connecting hole 14. The fifth port 635 is connected to the first port 11. The commutation component 63 has a first switching state and a second switching state. When the commutation component 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 commutation component 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.

[0189] During the specific operation of the air conditioning system 300, such as Figure 12 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.

[0190] 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.

[0191] 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 and the third port 51 is set to an open circuit state. 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 through the collector component 5, 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 then enters the heat exchange tube 41 of the second flow path 43 after being collected. This can further reduce the temperature of the refrigerant and increase the subcooling of the refrigerant, thereby forming a subcooling tube design for the condenser and better enhancing the heat exchange efficiency of the heat exchanger assembly 200.

[0192] Similarly, such as Figure 13 As shown in the example, when the air conditioning system 300 is in heating mode, when the reversing component 63 is in the second switching state, 631 is connected to the second port 632, and the third port 633 and the fourth port 634 are connected.

[0193] 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.

[0194] 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. After the refrigerant in the multiple flow paths is collected by the flow-collecting component 5, it flows out of the heat exchanger assembly 200 through the third port 51 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 heat exchange pattern can be formed, thereby improving the heat exchange efficiency of the heat exchanger assembly 200.

[0195] 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.

[0196] 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.

[0197] In some embodiments, 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 first port 631 to communicate with the fifth port 635 and the second port 632 to communicate with the third port 633, or to control the first port 631 to communicate with the second port 632 and the third port 633 to communicate with the fourth port 634.

[0198] According to the air conditioning system 300 of this utility model embodiment, a heat exchanger assembly 200 is provided. A flow-blocking component 2 allows the medium to flow only from the second port 12 to the first connecting hole 13. The flow-blocking component 2 can automatically open and close or cut off the flow, thereby automatically guiding the medium and changing its flow direction. A flow divider 8 ensures that the medium entering through the second port 12 is preferentially guided to the main body 1 and participates in heat exchange through the first connecting hole 13. When the flow divider 100 is used in the heat exchanger assembly 200 and the air conditioning system 300, it can automatically switch the medium's 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, improving the cooling or heating performance of the air conditioning system 300, and increasing energy efficiency. Furthermore, no other control structure is required, making the structure simple, easy to implement, and low in cost.

[0199] The following describes an air conditioner according to an embodiment of the present invention.

[0200] The air conditioner according to an embodiment of the present invention includes the air conditioning system 300 described above.

[0201] According to an embodiment of the present invention, an air conditioning system 300 is provided. A flow-blocking component 2 allows the medium to flow only from the second port 12 to the first connecting hole 13. This allows for automatic opening and closing or flow interception of the flow-blocking component 2, thereby automatically guiding the medium and changing its flow direction. A flow divider 8 prioritizes the medium entering through the second port 12 to the main body 1 and participates in heat exchange via the first connecting hole 13. When the flow divider assembly 100 is used in the heat exchanger assembly 200 and the air conditioning system 300, it can automatically switch the medium's 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, no other control structures are required, resulting in a simple, easy-to-implement, and low-cost structure.
