[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0053] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides a flow dividing component, including a housing 100 and a partition assembly 200. Figure 1As shown, the housing 100 is provided with a liquid inlet 110 and a liquid dispensing port 120; the partition assembly 200 is arranged in the housing 100 for separating the liquid inlet 110 and the liquid dispensing port 120, and the partition assembly 200 includes a first partition 210 and a second partition 220 that can move relatively; wherein the first partition 210 is provided with a first through hole 211, the second partition 220 is provided with a second through hole 221, and the first through hole 211 and the second through hole 221 are avoided; and the partition assembly 200 has a conducting position and a blocking position, and the conducting position corresponds to the spacing of the first partition 210 and the second partition 220, so that the liquid inlet 110 is connected to the liquid dispensing port 120 through the first through hole 211 and the second through hole 221 (as shown in FIG. 2 ). Figure 2 The blocking position corresponds to the first partition 210 and the second partition 220 being close to each other, and the first through hole 211 is blocked by the second partition 220, and the second through hole 221 is blocked by the first partition 210, so as to block the communication between the liquid inlet 110 and the liquid separation port 120 (as shown in FIG. Figure 3 shown).

[0054] In this embodiment, since the first through hole 211 and the second through hole 221 avoid each other, when the first partition 210 and the second partition 220 form a gap by moving, the first partition 210 avoids the second through hole 221, and the second partition 220 avoids the first through hole 211. At this time, the partition assembly 200 is located in the conduction position, and the refrigerant can flow from the liquid inlet 110, the first through hole 211, and the second through hole 221 to the liquid separation port 120 in sequence. When the first partition 210 and the second partition 220 are moved and abutted against each other, the first through hole 211 is blocked by the second partition 220, and the second through hole 221 is blocked by the first partition 210. At this time, the partition assembly 200 is located in the blocking position, and the liquid inlet 110 and the liquid separation port 120 are blocked by the partition assembly 200, and the refrigerant in the liquid inlet 110 cannot flow to the liquid separation port 120. Thus, the flow diversion and flow blocking of the diverter member can be realized by adjusting the position of the partition assembly 200. There is no need to separately install a valve such as a one-way valve or a solenoid valve on the refrigerant flow path before the diverter member to control the flow of the refrigerant.

[0055] In this embodiment, the first partition 210 and the second partition 220 can move relative to each other in the following cases: the first partition 210 is fixed, and the second partition 220 moves relative to the first partition 210; the second partition 220 is fixed, and the first partition 210 moves relative to the second partition 220; the first partition 210 and the second partition 220 can both move relative to or towards each other. No matter how the two partitions move, as long as they can move to a position where they are spaced apart or close to each other, the above cases all belong to the protection scope of this application.

[0056] In this embodiment, the first partition plate 210 and the second partition plate 220 are arranged parallel to each other, and the first through hole 211 and the second through hole 221 avoid each other, which means that the projection of the first through hole 211 on the second partition plate 220 avoids the second through hole 221, and the projection of the second through hole 221 on the first partition plate 210 avoids the first through hole 211.

[0057] Optionally, the first partition 210 is close to the liquid inlet 110 and is fixedly arranged; the second partition 220 is close to the liquid separation port 120 and can move relative to the first partition 210; when the fluid flows from the liquid inlet 110 to the liquid separation port 120, it drives the second partition 220 to move to the conduction position, and when the fluid flows from the liquid separation port 120 to the liquid inlet 110, it drives the second partition 220 to move to the blocking position.

[0058] In this embodiment, the power generated by the circulation of the refrigerant is used to drive the second partition plate 220 to move, without the need for an additional power source or control system. Figure 2 As shown, when the refrigerant flows from the liquid inlet 110 to the liquid separation port 120, since the first partition 210 is fixed, the refrigerant passes through the first through hole 211 to impact the second partition 220. Since the second partition 220 is movable, the refrigerant drives the second partition 220 to move in a direction away from the first partition 210, and the second partition 220 shown by the dotted line is in a moving state, and then moves to the conduction position. And, the interval is maintained under the continuous impact of the refrigerant. Thus, the liquid inlet 110 is connected to the liquid separation port 120 through the first through hole 211 and the second through hole 221, so as to realize the smooth circulation and liquid separation of the refrigerant.

[0059] like Figure 3 As shown, when the refrigerant flows from the liquid separation port 120 to the liquid inlet 110, the refrigerant impacts the second partition 220 and flows to the first partition 210 through the second through hole 221. Since the second partition 220 is movable, the refrigerant drives the second partition 220 to move toward the first partition 210. When it moves to abut against the first partition 210, that is, the blocking position, the second through hole 221 is blocked by the first partition 210. Since the first partition 210 is fixed, the second partition 220 and the first partition 210 remain in contact under the continuous impact of the refrigerant. Thereby, the refrigerant in the liquid separation port 120 is blocked from flowing to the liquid inlet 110. In this way, when the flow direction of the refrigerant is different, the partition assembly 200 automatically moves to the corresponding position, thereby realizing the unidirectional conduction function.

[0060] Optionally, the first partition 210 is close to the liquid separation port 120 and is fixedly arranged (not shown in the figure); the second partition 220 is close to the liquid inlet 110 and can move relative to the first partition 210; when the fluid flows from the liquid inlet 110 to the liquid separation port 120, it drives the second partition 220 to move to the blocking position, and when the fluid flows from the liquid separation port 120 to the liquid inlet 110, it drives the second partition 220 to move to the conducting position.

[0061] In this embodiment, when the refrigerant flows from the liquid separation port 120 to the liquid inlet 110, since the first partition 210 is fixed, the refrigerant passes through the first through hole 211 to impact the second partition 220. Since the second partition 220 is movable, the refrigerant drives the second partition 220 to move in a direction away from the first partition 210, and then moves to the conduction position. And, the interval is maintained under the continuous impact of the refrigerant. Thus, the liquid separation port 120 is connected to the liquid inlet 110 through the first through hole 211 and the second through hole 221, realizing the convergence and circulation of the refrigerant.

[0062] When the refrigerant flows from the liquid inlet 110 to the liquid separation port 120, the refrigerant impacts the second partition 220 and flows to the first partition 210 through the second through hole 221. Since the second partition 220 is movable, the refrigerant drives the second partition 220 to move toward the first partition 210. When it moves to abut against the first partition 210, that is, the blocking position, the second through hole 221 is blocked by the first partition 210. Since the first partition 210 is fixed, the second partition 220 and the first partition 210 remain in contact under the continuous impact of the refrigerant. As a result, the refrigerant cannot flow from the liquid inlet 110 to the liquid separation port 120.

[0063] Alternatively, if Figure 1 As shown, the housing 100 includes a first end surface 101 , and a liquid separation port 120 is disposed on the first end surface 101 , and the liquid separation port 120 corresponds to the second through hole 221 .

[0064] In this embodiment, the direct correspondence between the liquid separation port 120 and the second through hole 221 ensures that the fluid can smoothly flow out of the liquid separation port 120 after passing through the first through hole 211 and the second through hole 221 from the liquid inlet 110. In this way, the resistance of the refrigerant is reduced, and unnecessary flow and accumulation of the refrigerant inside the housing 100 are avoided, thereby improving the circulation efficiency of the refrigerant. In addition, when the second partition 220 moves to the conduction position, the plate surface of the second partition 220 facing away from the first partition 210 is in contact with the first end surface 101, and the first end surface 101 plays a role in limiting the movement of the second partition 220.

[0065] Alternatively, if Figure 2 As shown, the housing 100 further includes a second end surface 102 , the second end surface 102 is opposite to the first end surface 101 , and the liquid inlet 110 is disposed on the second end surface 102 .

[0066] In this embodiment, the second end face 102 is parallel to the first end face 101, a liquid inlet 110 is provided on the second end face 102, and two or more liquid separation ports 120 are provided on the first end face 101. Such a layout can realize multi-channel flow diversion of the refrigerant, and the structure of the overall flow diversion component is more compact and occupies less space.

[0067] Optionally, the housing 100 is configured as a cylinder, and the first partition plate 210 and the second partition plate 220 are both configured as circular plates. In addition, the peripheries of the first partition plate 210 and the second partition plate 220 are both in contact with the inner wall of the housing 100 .

[0068] In this embodiment, the circular partition design cooperates with the cylindrical shell 100, so that the entire partition assembly can evenly distribute stress when subjected to force, avoiding the occurrence of stress concentration. This is conducive to improving stability and reducing structural damage caused by stress concentration. In addition, since the periphery of the first partition 210 and the second partition 220 are closely attached to the inner wall of the cylindrical shell 100, the sealing of the overall diversion component can be enhanced.

[0069] Optionally, the partition assembly 200 further includes a guide shaft 230 . The guide shaft 230 is disposed through the second partition 220 and arranged along the moving direction of the second partition 220 ; and a first end of the guide shaft 230 is connected to the first partition 210 , and a second end thereof is connected to the housing 100 .

[0070] In this embodiment, the movement accuracy of the second partition plate 220 can be improved by the guide shaft 230. Due to the guidance of the second partition plate 220 by the guide shaft 230, the second partition plate 220 can be accurately moved to the conducting position or the blocking position, ensuring the conduction or blocking between the liquid inlet 110 and the liquid separation port 120. In addition, the guide shaft 230 can also reduce the wear and noise of the second partition plate 220 during the movement, reduce friction and vibration, and thus extend the service life of the diversion component.

[0071] Optionally, the first end of the guide shaft 230 is fixed to the center of the first partition 210, and the second end of the guide shaft 230 is fixed to the center of the first end surface 101. In this way, the central fixed design enables the guide shaft 230 to have higher structural strength and rigidity, so that it can resist external impact and vibration and maintain stable operation of the system. Here, if the center of the first partition 210 is the first through hole 211, the guide shaft 230 can be fixed to the hole wall of the first through hole 211 through a supporting structure.

[0072] Optionally, the cross section of the guide shaft 230 is configured as a polygon to prevent the second partition 220 from rotating relative to the first partition 210. Here, preferably, the cross section of the guide shaft is configured as a triangle, and the second partition 220 is provided with an axis hole 231 adapted to the cross section of the guide shaft 230.

[0073] In this embodiment, the polygonal cross-sectional shape makes the contact surface between the guide shaft 230 and the second partition plate 220 non-circular, so when the second partition plate 220 moves along the guide shaft 230, the polygonal structure can prevent it from rotating. In this way, the avoidance state of the first through hole 211 and the second through hole 221 can be maintained, and the corresponding state of the second through hole 221 and the liquid separation port 120 can be maintained. Therefore, it can be ensured that the partition plate assembly 200 can normally play the role of conducting, diverting and blocking in the conducting position and the blocking position.

[0074] Optionally, the first through hole 211 is configured to be circular, annular, sector-shaped, elliptical, polygonal or irregular in shape.

[0075] Optionally, the second through hole 221 is configured as a circle, annular ring, sector, ellipse, polygon or irregular shape. The shapes of the first through hole 211 and the second through hole 221 are not specifically limited here, and it is only necessary to ensure that the first through hole 211 and the second through hole 221 avoid each other.

[0076] For example, Figure 4 As shown, the first through hole 211 is an irregular shape, and the second through hole 221 is a circle. When the partition assembly 200 is in the blocking position, the first through hole 211 is blocked by the second partition 220, and the second through hole 221 is blocked by the first partition 210. Figure 4 Shown in shaded area.

[0077] Another exemplary example is, Figure 5 As shown, the first through hole 211 is circular, and the second through hole 221 is circular. When the partition assembly 200 is in the blocking position, the first through hole 211 is blocked by the second partition 220, and the second through hole 221 is blocked by the first partition 210. Figure 5 Shown in shaded area.

[0078] The embodiment of the present disclosure further provides a variable split heat exchanger 300, comprising the split component described in any of the above embodiments.

[0079] Optionally, the variable diversion heat exchanger 300 also includes a plurality of first heat exchange branches, each of which is connected to a liquid separation port 120; and when the variable diversion heat exchanger 300 is used as an evaporator, the partition assembly 200 is located in a conducting position so that at least part of the first heat exchange branches are connected in parallel; when the variable diversion heat exchanger 300 is used as a condenser, the partition assembly 200 is located in a blocking position so that at least part of the first heat exchange branches are connected in series, thereby realizing variable diversion.

[0080] Exemplarily, the plurality of first heat exchange branches include branch No. 1 301, branch No. 2 302 and branch No. 3 303. The variable flow split heat exchanger 300 also includes a second heat exchange branch, referred to as branch No. 4 304. In addition, the flow splitting component is provided with outlet No. 1 121, outlet No. 2 122 and outlet No. 3 123. Among them, the first end of branch No. 1 301 is connected to outlet No. 1 121, and the second end thereof is connected to the first header 310; the first end of branch No. 2 302 is connected to outlet No. 2 122, and the second end thereof is connected to the first header 310; the first end of branch No. 303 is connected to outlet No. 3 123, and the second end thereof is connected to the second header 320; the first end of branch No. 4 304 is connected to the liquid inlet 110, and the second end thereof is connected to the second header 320. Furthermore, the first header 310 is connected to the second header 320 via the one-way valve 330 , and the conducting direction of the one-way valve 330 is limited to flow from the second header 320 to the first header 310 .

[0081] In the present embodiment, the first manifold 310 and the second manifold 320 can be independently arranged, and the one-way valve 330 is arranged between the two. The first manifold 310 and the second manifold 320 can also constitute an integral structure, and the one-way valve 330 can be arranged inside the integral structure. Here, the diverter component also plays a role of one-way conduction, and the partition assembly 200 is located in the conduction position when the refrigerant flows from the liquid inlet 110 to the liquid separation port 120, so that the first branch 301, the second branch 302 and the third branch 303 are connected in parallel. When the refrigerant flows from the liquid separation port 120 to the liquid inlet 110, the partition assembly 200 is located in the blocking position, so that the first branch 301 and the third branch 303, the second branch 302 and the third branch 303 are connected in series.

[0082] The embodiment of the present disclosure further provides an air conditioner, comprising the variable split heat exchanger 300 described in any of the above embodiments.

[0083] Optionally, the variable split heat exchanger 300 is used as an outdoor unit of the air conditioner. When the air conditioner is heating, the variable split heat exchanger 300 is used as an evaporator; when the air conditioner is cooling, the variable split heat exchanger 300 is used as a condenser.

[0084] In this embodiment, the structure of the diversion component is as follows: Figure 2 and Figure 3As shown, the first partition 210 is fixed and the second partition 220 is movable. When the variable flow split heat exchanger 300 is used as an evaporator, the refrigerant enters the shell 100 from the liquid inlet 110 of the flow splitting component, and the partition assembly 200 is in the conducting position. The refrigerant flows to the three liquid splitting ports 120 from the liquid inlet 110, the first through hole 211, and the second through hole 221 in sequence. The refrigerant of the No. 1 outlet 121 flows from the No. 1 branch 301 to the first header 310, the refrigerant of the No. 2 outlet 122 flows from the No. 2 branch 302 to the first header 310, and the refrigerant of the No. 3 outlet 123 flows from the No. 3 branch 303 to the second header 320. In this way, the No. 1 branch 301, the No. 2 branch 302 and the No. 3 branch 303 are connected in parallel, thereby greatly reducing the pressure drop and increasing the system pressure while ensuring the heat transfer coefficient, thereby improving the low-temperature heating capacity of the air conditioner. Furthermore, the refrigerant in the fourth branch 304 flows to the second header 320, and the refrigerant in the second header 320 flows to the first header 310 through the one-way valve 330, and finally flows out of the heat exchanger. Figure 6 As indicated by the arrow.

[0085] When the variable split heat exchanger 300 is used as a condenser, the refrigerant flows from the first header 310 to branch No. 1 301 and branch No. 2 302, and then enters the shell 100 from outlet No. 1 121 and outlet No. 2 122 respectively. At this time, the partition assembly 200 is in a blocked position, and the refrigerant cannot flow to the liquid inlet 110. The refrigerant in the shell 100 can only flow from branch No. 303 to the second header 320, so that branch No. 1 301 and branch No. 303, and branch No. 2 302 and branch No. 303 are connected in series, thereby accelerating the circulation and increasing the heat transfer coefficient, thereby improving the high-temperature cooling capacity of the air conditioner. Finally, the refrigerant in the second header 320 flows out of the heat exchanger through branch No. 4 304. The above-mentioned refrigerant flow path is as follows: Figure 7 As indicated by the arrow.

[0086] It can be seen that the refrigerant flows in different directions when the air conditioner is cooling and heating, respectively. Moreover, under the action of the partition assembly 200, the refrigerant forms different flow paths, thereby improving the overall performance of the heat exchanger and the air conditioner.
