[0019] The second annular wall surface is connected to the second end of the circumferential side wall and serves as the limiting component; when the fluid drives the second partition to move to the conducting position, the second annular wall surface blocks the second partition from moving towards the liquid distribution port.

[0020] Optionally, the peripheries of the first partition and the second partition are both in contact with the circumferential side wall.

[0031] Since the first through hole and the second through hole avoid each other, when the first partition and the second partition form a gap by moving, the first partition avoids the second through hole and the second partition avoids the first through hole. At this time, the partition assembly is in the conducting position, and the limiting assembly plays a limiting role, and the refrigerant can flow from the liquid inlet, the first through hole, and the second through hole to the liquid distribution port in sequence. When the first partition and the second partition are abutted against each other by moving, the first through hole is blocked by the second partition and the second through hole is blocked by the first partition. At this time, the partition assembly is in the blocking position, and the liquid inlet and the liquid distribution port are blocked by the partition assembly, and the refrigerant at the liquid inlet cannot flow to the liquid distribution port. In this way, by adjusting the position of the partition assembly, the conducting and diverting and blocking of the header member can be achieved. 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 header member to control the on-off of the refrigerant.

[0053] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0054] Combined Figure 1-8 As shown, the embodiments of the present disclosure provide a header member, including a pipe body 100, a partition assembly 200 and a limiting assembly 140. As Figure 1As shown, the pipe body 100 is provided with a liquid inlet 110 and a liquid distribution port 120; a partition assembly 200 is arranged inside the pipe body 100 for separating the liquid inlet 110 and the liquid distribution port 120, and the partition assembly 200 includes a first partition 210 and a second partition 220 that can move relative to each other; 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 from each other; and, the partition assembly 200 has a conducting position and a blocking position, the conducting position corresponds to the first partition 210 and the second partition 220 being spaced apart, so that the liquid inlet 110 is connected to the liquid distribution port 120 through the first through hole 211 and the second through hole 221 (as Figure 3 shown); the blocking position corresponds to the first partition 210 and the second partition 220 being in contact with 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 to block the connection between the liquid inlet 110 and the liquid distribution port 120 (as Figure 4 shown). The limiting assembly 140 is used to limit the partition assembly 200 in the conducting position.

[0055] In this embodiment, since the first through hole 211 and the second through hole 221 are avoided from each other, when the first partition 210 and the second partition 220 form a space through movement, 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 in the conducting position, and the limiting assembly 140 plays a limiting role, and the refrigerant can flow from the liquid inlet 110, the first through hole 211, and the second through hole 221 to the liquid distribution port 120 in sequence. When the first partition 210 and the second partition 220 are in contact with each other through movement, 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 in the blocking position, and the connection between the liquid inlet 110 and the liquid distribution port 120 is blocked by the partition assembly 200, and the refrigerant at the liquid inlet 110 cannot flow to the liquid distribution port 120. In this way, by adjusting the position of the partition assembly 200, the on-off and diversion of the header member can be realized. There is no need to separately install a valve such as a check valve or a solenoid valve on the refrigerant flow path before the header member to control the on-off of the refrigerant.

[0056] In this embodiment, the situations where the first partition 210 and the second partition 220 can move relative to each other include: 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 in contact with each other. The above situations are all within the protection scope of this application.

[0057] In this embodiment, the first partition 210 and the second partition 220 are arranged parallel to each other. The avoidance of the first through-hole 211 and the second through-hole 221 means that the projection of the first through-hole 211 on the second partition 220 avoids the second through-hole 221, and the projection of the second through-hole 221 on the first partition 210 avoids the first through-hole 211.

[0058] Optionally, as Figure 2 shown, the first partition 210 is close to the liquid inlet 110 and is fixedly arranged; the second partition 220 is close to the liquid distribution port 120 and is movable relative to the first partition 210; when the fluid flows from the liquid inlet 110 to the liquid distribution port 120, the second partition 220 is driven to move to the conducting position, and when the fluid flows from the liquid distribution port 120 to the liquid inlet 110, the second partition 220 is driven to move to the blocking position.

[0059] In this embodiment, the power generated during the circulation of the refrigerant is utilized to drive the movement of the second partition 220, without the need for an additional power source or control system. As Figure 3 shown, when the refrigerant flows from the liquid inlet 110 to the liquid distribution port 120, since the first partition 210 is fixed, the refrigerant passes through the first through-hole 211 and impacts 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 conducting position. And, it remains spaced under the continuous impact of the refrigerant. Thus, the liquid inlet 110 is connected to the liquid distribution port 120 through the first through-hole 211 and the second through-hole 221, realizing the smooth circulation and liquid distribution of the refrigerant.

[0060] As Figure 4 shown, when the refrigerant flows from the liquid distribution 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 towards 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 abutment under the continuous impact of the refrigerant. Thus, the refrigerant flow from the liquid distribution port 120 to the liquid inlet 110 is blocked. 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 one-way conduction function.

[0061] Optionally, the first partition 210 is close to the liquid distribution port 120 and is fixedly arranged (not shown in the figure); the second partition 220 is close to the liquid inlet 110 and is movable relative to the first partition 210; when the fluid flows from the liquid inlet 110 to the liquid distribution port 120, the second partition 220 is driven to move to the blocking position, and when the fluid flows from the liquid distribution port 120 to the liquid inlet 110, the second partition 220 is driven to move to the conducting position.

[0062] In this embodiment, when the refrigerant flows from the liquid separation port 120 to the liquid inlet port 110, since the first partition plate 210 is fixed, the refrigerant passes through the first through hole 211 and impacts the second partition plate 220. Since the second partition plate 220 is movable, the refrigerant drives the second partition plate 220 to move in a direction away from the first partition plate 210, and then moves to the conduction position. And, it maintains an interval under the continuous impact of the refrigerant. Thus, the liquid separation port 120 is connected to the liquid inlet port 110 through the first through hole 211 and the second through hole 221, realizing the confluence and circulation of the refrigerant.

[0063] When the refrigerant flows from the liquid inlet port 110 to the liquid separation port 120, the refrigerant impacts the second partition plate 220 and flows through the second through hole 221 to the first partition plate 210. Since the second partition plate 220 is movable, the refrigerant drives the second partition plate 220 to move towards the first partition plate 210. When it moves to abut against the first partition plate 210, that is, the blocking position, the second through hole 221 is blocked by the first partition plate 210. Since the first partition plate 210 is fixed, the second partition plate 220 and the first partition plate 210 maintain abutment under the continuous impact of the refrigerant. Thus, the refrigerant cannot flow from the liquid inlet port 110 to the liquid separation port 120.

[0064] Optionally, the inner diameter of a part of the pipe body 100 expands outwards to form a receiving pipe section 130, and the partition plate assembly 200 is arranged in the receiving pipe section 130.

[0065] In this embodiment, the axis of the receiving pipe section 130 is still coaxially arranged with the axis of the pipe body 100. Here, the inner diameter of the receiving pipe section 130 is larger, thereby increasing the space inside the pipe body 100 and providing an installation space for the partition plate assembly 200.

[0066] Optionally, as Figure 2 shown, the receiving pipe section 130 includes a circumferential side wall 133, a first annular wall surface 131, and a second annular wall surface 132. Among them, the first end of the circumferential side wall 133 is close to the liquid inlet port 110, and its second end is close to the liquid separation port 120; the first annular wall surface 131 is connected to one end of the circumferential side wall 133 and is used for arranging the first partition plate 210; the second annular wall surface 132 is connected to the second end of the circumferential side wall 133 and serves as the limiting component 140; when the fluid drives the second partition plate 220 to move to the conduction position, the second annular wall surface 132 blocks the second partition plate 220 from moving towards the liquid separation port 120.

[0067] In this embodiment, when the pipe body 100 is placed vertically, the liquid inlet 110 is located at the lower part of the accommodating pipe section 130, and the liquid distribution port 120 is located at the upper part of the accommodating pipe section 130. Moreover, the first annular wall surface 131 is located at the upper part of the circumferential side wall 133, and the second annular wall surface 132 is located at the lower part of the circumferential side wall 133. The circumferential side wall 133 serves as the main structure, connecting the liquid inlet 110 and the liquid distribution port 120; the first annular wall surface 131 is used to install the first partition 210, ensuring the stability of the first partition 210; the second annular wall surface 132 serves as the limiting component 140, playing a role in blocking the second partition 220.

[0068] Optionally, the peripheries of the first partition 210 and the second partition 220 are both in contact with the circumferential side wall 133.

[0069] In this embodiment, the design of the peripheries in contact enhances the connection stability between the first partition 210 and the second partition 220 and the circumferential side wall 133, which is beneficial for the partition assembly 200 to better resist deformation and displacement when subjected to fluid impact or external pressure. Moreover, it is beneficial to prevent the refrigerant from flowing through the gap between the partition assembly 200 and the circumferential side wall 133, improving the sealing performance.

[0070] Optionally, as Figure 5 shown, the limiting component 140 includes a limiting protrusion. The limiting protrusion is provided on the inner wall of the pipe body 100 and is located on the side of the second partition 220 facing the liquid distribution port 120. In this way, the movement distance of the second partition 220 can be effectively limited by the limiting protrusion, ensuring that the second partition 220 will not move excessively when it moves to the conducting position.

[0071] Optionally, a plurality of limiting protrusions are arranged around the inner wall of the pipe body 100 and are all located on the cross-section of the pipe body 100.

[0072] Exemplarily, two limiting protrusions are oppositely provided on the inner wall of the pipe body 100. When the second partition 220 moves to the conducting position, the two limiting protrusions simultaneously resist the second partition 220, thus forming an effective limit.

[0073] Another exemplarily, four limiting protrusions are arranged around the inner wall of the pipe body 100. When the second partition 220 moves to the conducting position, the four limiting protrusions simultaneously resist the second partition 220, thus forming an effective limit.

[0074] Optionally, the liquid distribution port 120 is provided at the end of the pipe body 100, and / or the liquid distribution port 120 is provided on the side wall of the pipe body 100.

[0075] Exemplarily, the header member includes three liquid distribution ports 120, referred to as the first outlet 121, the second outlet 122, and the third outlet 123. Among them, the first outlet 121 is disposed at the upper end of the pipe body 100, and the second outlet 122 and the third outlet 123 are disposed on the side wall of the pipe body 100.

[0076] Optionally, Figure 6 is a schematic diagram of the partition assembly 200. Among them, the first through hole 211 is configured to be circular (such as Figure 6-1 ), circular ring-shaped, fan-shaped, oval-shaped, polygonal, or irregularly shaped.

[0077] Optionally, the second through hole 221 is configured to be circular, circular ring-shaped (such as Figure 6-2 ), fan-shaped, oval-shaped, polygonal, or irregularly shaped. Figure 6-3 The shaded part of represents the blocked first through hole 211 and second through hole 221. Here, the shapes of the first through hole 211 and the second through hole 221 are not specifically limited, as long as it is ensured that the first through hole 211 and the second through hole 221 avoid each other.

[0078] The embodiment of the present disclosure also provides a variable flow-dividing heat exchanger 300, including the header member described in any of the above embodiments.

[0079] Optionally, the variable flow-dividing heat exchanger 300 further includes a plurality of first heat exchange branches, which are respectively connected to one liquid distribution port 120; and when the variable flow-dividing heat exchanger 300 is used as an evaporator, the partition assembly 200 is in the conducting position to make at least part of the first heat exchange branches in parallel; when the variable flow-dividing heat exchanger 300 is used as a condenser, the partition assembly 200 is in the blocking position to make at least part of the first heat exchange branches in series, so as to achieve variable flow division.

[0080] Exemplarily, as Figure 7 shown, the plurality of first heat exchange branches include a first branch 301, a second branch 302, and a third branch 303. The variable flow-dividing heat exchanger 300 further includes a second heat exchange branch, referred to as a fourth branch 304. And, the three liquid distribution ports 120 of a header member (referred to as the right header member) are called the first outlet 121, the second outlet 122, and the third outlet 123. The three liquid distribution ports 120 of another header member (referred to as the left header member) are called the fourth outlet 124, the fifth outlet 125, and the sixth outlet 126. Among them, the two ends of the first branch 301 are respectively connected to the first outlet 121 and the fifth outlet 125, the two ends of the second branch 302 are respectively connected to the second outlet 122 and the sixth outlet 126, and the two ends of the third branch 303 are respectively connected to the third outlet 123 and the manifold 310. And the liquid inlet 110 of the left header member is connected to the manifold 310.

[0081] In this embodiment, both header components play a role of unidirectional conduction. When the refrigerant flows into the liquid inlet 110 of the right header component, the partition assemblies 200 of both header components are in the conducting position. At this time, the first branch 301, the second branch 302, and the third branch 303 are in parallel. The refrigerant enters the chamber from the fourth outlet 124 of the right header component, and the partition assemblies 200 of both header components are in the blocking position. At this time, the first branch 301 and the third branch 303, and the second branch 302 and the third branch 303 are in series.

[0082] The embodiment of the present disclosure also provides an air conditioner, including the variable flow dividing heat exchanger 300 described in any of the above embodiments.

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

[0084] In this embodiment, the structure of the header component is as Figure 1 and Figure 2 shown, the first partition 210 is fixed and the second partition 220 is movable. When the variable flow dividing heat exchanger 300 serves as an evaporator, when the refrigerant flows into the liquid inlet 110 of the right header component, the partition assemblies 200 of both header components are in the conducting position. The refrigerant at the first outlet 121 flows through the first branch 301 to the fifth outlet 125, the refrigerant at the second outlet 122 flows through the second branch 302 to the sixth outlet 126, and the refrigerant at the third outlet 123 flows through the third branch 303 to the manifold 310. In this way, the first branch 301, the second branch 302, and the third branch 303 are in parallel, so as to greatly reduce the pressure drop while ensuring the heat transfer coefficient and improve the system pressure, thereby improving the low-temperature heating capacity of the air conditioner. And, the refrigerant in the fourth branch 304 flows to the manifold 310, the refrigerant in the manifold 310 flows into the liquid inlet 110 of the left header component, and finally the refrigerant flows out of the heat exchanger from the fourth outlet 124. The above refrigerant flow path is as Figure 7 shown by the arrows.

[0085] When the variable flow split heat exchanger 300 is used as a condenser, the refrigerant flows in from the fourth outlet 124 of the left header member, and the partition assemblies 200 of both header members are in the blocking positions. The refrigerant in the left header member can only: flow from the fifth outlet 125 to the first outlet 121 through the first branch 301, and flow from the sixth outlet 126 to the second outlet 122 through the second branch 302. Then, the refrigerant in the right header member can only flow from the third outlet 123 to the manifold 310. In this way, the first branch 301 and the third branch 303, and the second branch 302 and the third branch 303 are in series, thereby accelerating the cycle and increasing the heat transfer coefficient, and thus enhancing the high-temperature refrigeration capacity of the air conditioner. Finally, the refrigerant in the manifold 310 flows out of the heat exchanger through the fourth branch 304. The above refrigerant flow path is as shown by the arrows in Figure 8 as follows.

[0086] It can be seen that when the air conditioner cools and heats respectively, the flow directions of the refrigerant are different. Moreover, under the action of the partition assembly 200, different flow paths of the refrigerant are formed, thereby enhancing the overall performance of the heat exchanger and the air conditioner.
