[0067] The variable split flow heat exchanger 500 disclosed in the related art has a header component such as Figure 1 As shown. The manifold 100 includes a first pipe section 110 and a second pipe section 120, and the first end of the first pipe section 110 is connected to the second pipe section 120 through a first one-way valve 131. The first pipe section 110 is provided with a first flow outlet 111, and the second pipe section 120 is provided with a second flow outlet 121. The first liquid separation section 340 and the second liquid separation section 350 are connected to the first flow outlet 111 through a connecting pipe 370, and the third liquid separation section 360 is connected to the second flow outlet 121. Figure 2 As shown, the variable flow split heat exchanger 500 further includes a converging manifold 400, which includes a third pipe segment 401 and a fourth pipe segment 402, and the third pipe segment 401 is connected to the fourth pipe segment 402 through a second one-way valve 141. In addition, the two ends of the first branch 410 are respectively connected to the first liquid separation segment 340 and the third pipe segment 401, the two ends of the second branch 420 are respectively connected to the second liquid separation segment 350 and the fourth pipe segment 402, and the two ends of the third branch 430 are respectively connected to the third liquid separation segment 360 and the fourth pipe segment 402.

[0068] The variable split heat exchanger 500 disclosed in the related art can be used as an outdoor unit of an air conditioner, and the variable split heat exchanger 500 is used as an evaporator when the air conditioner is heating. The refrigerant flow direction is as follows: Figure 3 As shown by the arrows, here, since the manifold 100 is relatively high and the one-way valve has a certain resistance, it is easy for the refrigerant to fail to reach the top, thereby causing uneven liquid separation between the No. 1 branch 410 and the No. 2 branch 420 .

[0069] Combination Figure 4-9 As shown, an embodiment of the present disclosure provides a manifold component. The manifold component includes a manifold 100, and the manifold 100 includes a first pipe segment 110 and a second pipe segment 120; wherein the first end of the first pipe segment 110 is connected to the second pipe segment 120 through a conducting component, and the second end of the first pipe segment 110 is provided with a first flow outlet 111; the liquid distributor 300 is connected to the first flow outlet 111, and the axis of the liquid distributor 300 is coaxially arranged with the axis of the first pipe segment 110, and the diameter of the liquid distributor 300 is smaller than the diameter of the manifold 100.

[0070] In this embodiment, the refrigerant flows from the second pipe section 120 and the conducting component to the first pipe section 110 in sequence, and then flows out from the liquid distributor 300. Here, the liquid distributor 300 and the manifold 100 are coaxially arranged, which shortens the height of the manifold 100 itself in design, and the position of the first flow outlet 111 is also relatively low, which is conducive to the refrigerant rushing to the top of the manifold 100. In addition, the design that the diameter of the liquid distributor 300 is smaller than the diameter of the manifold 100 can increase the flow rate of the refrigerant in the liquid distributor 300 by changing the pipe diameter, thereby ensuring the subsequent liquid distribution is uniform.

[0071] Optionally, the conducting component is configured to be unidirectionally conducting, and the conducting direction is limited to flowing from the second pipe segment 120 to the first pipe segment 110 .

[0072] In this embodiment, the conduction component includes a one-way valve or a solenoid valve externally disposed at the connection between the first pipe segment 110 and the second pipe segment 120, such as the first valve component 130. Alternatively, the conduction component includes a one-way conduction structure built into the connection between the first pipe segment 110 and the second pipe segment 120. The one-way conduction structure may be a one-way valve or a solenoid valve built into the pipe body, or may be other one-way conduction structures built into the pipe body, such as a baffle structure that can only be flipped in one direction. No specific limitation is made here.

[0073] Alternatively, if Figure 6 As shown, the diameter of the manifold 100 is d1, the diameter of the liquid dispensing tube 300 is d2, and 1.35≤d1 / d2≤3.37.

[0074] In this embodiment, by limiting the ratio range of d1 / d2, sufficient fluid pressure and flow rate can be maintained in the liquid dispensing tube 300. A too large d1 / d2 ratio may cause the fluid flow rate in the liquid dispensing tube 300 to be too high, increasing energy loss and noise; while a too small ratio may cause the fluid flow rate in the liquid dispensing tube 300 to be too low, affecting the fluid distribution effect. In this way, an appropriate diameter ratio is conducive to reducing the energy loss of the refrigerant during the transmission process and is conducive to improving the liquid dispensing effect.

[0075] Exemplarily, the diameters referred to by d1 and d2 are both the inner diameters of the tube, and the value of d1 / d2 can be selected as 1.35, 1.4, 1.45, 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, 2, 2.35, 2.5, 2.75, 3, 3.15 or 3.37.

[0076] As another example, the diameters referred to by d1 and d2 are both the outer diameters of the tube, and the value of d1 / d2 can be selected as 1.35, 1.4, 1.45, 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, 2, 2.35, 2.5, 2.75, 3, 3.15 or 3.37.

[0077] Alternatively, if Figure 5 As shown, the liquid dispensing tube 300 includes a vertical section 320, an upper horizontal section 310 and a plurality of liquid dispensing sections. The first end of the vertical section 320 is connected to the first outlet 111, and its axis is coaxial with the axis of the first pipe section 110; the first end of the upper horizontal section 310 is connected to the second end of the vertical section 320, and its axis is perpendicular to the axis of the first pipe section 110; and the plurality of liquid dispensing sections are connected to the second end of the upper horizontal section 310.

[0078] In this embodiment, the refrigerant of the first flow outlet 111 flows from the vertical section 320 and the upper horizontal section 310 to the multiple liquid separation sections in turn, and the multiple liquid separation sections are respectively connected to the multiple first heat exchange branches, thereby realizing diversion. Since the height of the manifold 100 used in this application is relatively low, in order to meet the installation height requirement of the liquid separation section, the liquid separation section can reach the installation height by extending the length of the vertical section 320. In addition, the combined layout of the overall vertical section 320, the upper horizontal section 310 and the multiple liquid separation sections makes the design structure of the liquid separation pipe 300 compact and occupies less space.

[0079] Alternatively, if Figure 6 As shown, the length of the vertical section 320 is H1, and 13 mm ≤ H1 ≤ 196 mm.

[0080] Exemplarily, the value of H1 can be selected as 13mm, 15mm, 20mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 90mm, 100mm, 110mm, 130mm, 150mm, 170mm, 190mm or 196mm.

[0081] Alternatively, if Figure 6 As shown, the length of the upper transverse section 310 is H2, and H2 ≥ 10 mm.

[0082] Exemplarily, the value of H2 can be selected as 10mm, 13mm, 15mm, 18mm, 20mm, 25mm, 27mm, 30mm, 33mm, 35mm, 37mm, 40mm, 42mm, 44mm, 46mm, 48mm or 50mm.

[0083] Optionally, the upper transverse section 310 is connected to the vertical section 320 via a bending section, and the bending radius of the bending section is ≥10 mm.

[0084] Exemplarily, the bending radius of the bending section may be selected to be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm or 20 mm.

[0085] Optionally, the plurality of liquid separation sections include a first liquid separation section 340 and a second liquid separation section 350. The first end of the first liquid separation section 340 is connected to the upper horizontal section 310; the first end of the second liquid separation section 350 is connected to the upper horizontal section 310 and is located below the first liquid separation section 340; and the first liquid separation section 340, the second liquid separation section 350 and the upper horizontal section 310 are in a horizontal Y-shaped structure. Here, the Y-shaped structure allows the first liquid separation section 340 and the second liquid separation section 350 to be arranged vertically, making full use of the space and making the entire liquid separation system compact.

[0086] Optionally, the first flow outlet 111 is provided with an inserting section 330 , and the liquid dispensing tube 300 is inserted into the inserting section 330 to communicate with the first flow outlet 111 .

[0087] In this embodiment, the vertical section 320 of the liquid dispensing tube 300 is inserted into the plug section 330, thereby connecting the first outlet 111. The vertical section 320 and the first pipe section 110 are plug-connected by the plug section 330, and the stability and sealing of the connection are ensured by close fit, which is conducive to preventing refrigerant leakage.

[0088] Alternatively, if Figure 6 As shown, the length of the plug section 330 is H3, and H3≥8 mm.

[0089] Exemplarily, the value of H3 can be selected as 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm or 14.5mm.

[0090] Optionally, the manifold assembly further includes a liquid inlet pipe 200, which includes an acceleration section 210 and a connection section 220. The axis of the acceleration section 210 is arc-shaped, and is used to accelerate and separate the gas-liquid two-phase refrigerant flowing through; the first end of the connection section 220 is connected to the acceleration section 210, and the second end thereof is connected to the second pipe section 120.

[0091] In this embodiment, the refrigerant flows from the acceleration section 210 and the connection section 220 to the second pipe section 120 in sequence. Here, the axis of the acceleration section 210 is arc-shaped, which has a certain centrifugal and acceleration effect. Preferably, the axis of the acceleration section 210 is U-shaped. After the refrigerant passes through the U-shaped acceleration section 210, due to the centrifugal force, the liquid refrigerant in the two-phase refrigerant gathers on the outside of the U-shaped curved wall, and the gaseous refrigerant gathers in the middle of the U-shaped curved wall, forming an unevenly mixed gas-liquid two-phase state.

[0092] Optionally, the acceleration section 210 and the connection section 220 are integrally formed.

[0093] Optionally, the second end of the second pipe section 120 is provided with a constriction, and the second end of the connecting section 220 is inserted into the constriction.

[0094] Optionally, the manifold assembly further includes a discrete element 221. The discrete element 221 is disposed in the connecting section 220 and is used to discrete the refrigerant flowing through the connecting section.

[0095] In this embodiment, by providing a discrete element 221 in the connecting section 220, it is helpful to break up the gas-liquid two-phase refrigerant flowing out of the acceleration section 210, thereby improving the mixing uniformity of the refrigerant. The discrete element 221 can be a plate-like structure with holes, or other structures, and the material of the discrete element 221 can be metal or fabric.

[0096] Exemplarily, the discrete element 221 has a plurality of liquid balancing holes to disperse and mix the gas-liquid two-phase refrigerant. Preferably, the liquid balancing holes of the discrete element 221 are larger than or equal to 5 mm to prevent the liquid balancing holes from throttling the refrigerant.

[0097] In another exemplary embodiment, the discrete element 221 includes a multi-layer liquid equilibrating structure, and each layer of the liquid equilibrating structure is provided with a liquid equilibrating hole. This is conducive to improving the mixed flow effect of the gas-liquid two-phase refrigerant. Preferably, the liquid equilibrating holes in the multi-layer liquid equilibrating structure are arranged in an interlaced manner.

[0098] Alternatively, if Figure 4 As shown, the axes of the first pipe section 110, the second pipe section 120 and the connecting section 220 are coaxially arranged; wherein, the distance between the second end of the first pipe section 110 and the first end of the connecting section 220 is H4, and 115mm≤H4≤300mm.

[0099] Exemplarily, the value of H4 can be selected as 115mm, 120mm, 125mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, 260mm, 270mm, 280mm, 290mm or 300mm.

[0100] Optionally, the second pipe section 120 is provided with a second outflow port 121 , and the second outflow port 121 is provided with a third liquid separation section 360 . Here, the second outflow port 121 is provided on a side wall of the second pipe section 120 .

[0101] The embodiment of the present disclosure further provides a variable split heat exchanger 500, comprising the manifold component described in any of the above embodiments.

[0102] Optionally, the variable split heat exchanger 500 also includes a plurality of first heat exchange branches, all of which are connected to the first flow outlet 111 through the liquid distribution pipe 300; and when the variable split heat exchanger 500 is used as a condenser, the conducting component can connect at least some of the first heat exchange branches in series; when the variable split heat exchanger 500 is used as an evaporator, the conducting component can connect at least some of the first heat exchange branches in parallel.

[0103] For example, Figure 7 As shown, the plurality of first heat exchange branches include a first branch 410 and a second branch 420, and the first end of the first branch 410 is connected to the first liquid separation section 340, and the first end of the second branch 420 is connected to the second liquid separation section 350. The conducting component adopts a unidirectional first valve component 130, and the refrigerant can only flow from the second pipe section 120 to the first pipe section 110. When the variable split heat exchanger 500 is used as a condenser, the first valve component 130 is blocked, and the first branch 410 and the second branch 420 are connected in series; when the variable split heat exchanger 500 is used as an evaporator, the first valve component 130 is connected, and the first branch 410 and the second branch 420 are connected in parallel.

[0104] Optionally, the variable flow split heat exchanger 500 further includes a converging manifold 400 and a third branch 430. The converging manifold 400 includes a third pipe segment 401 and a fourth pipe segment 402, and the third pipe segment 401 is connected to the fourth pipe segment 402 through the second valve component 140. The second valve component 140 includes a valve configured to be unidirectionally conductive, and the conductive direction is limited to flow from the fourth pipe segment 402 to the third pipe segment 401. The first end of the third branch 430 is connected to the second outlet 121.

[0105] For example, the second end of the first branch 410 is connected to the third pipe section 401, the second end of the second branch 420 is connected to the fourth pipe section 402, and the second end of the third branch 430 is connected to the fourth pipe section 402. When the variable split heat exchanger 500 is used as an evaporator, the refrigerant flow path is as follows: Figure 8 When the variable split flow heat exchanger 500 is used as a condenser, the refrigerant flow path is as follows Fig. 9 shown.

[0106] An embodiment of the present disclosure provides an air conditioner, comprising the variable split heat exchanger 500 described in any of the above embodiments.

[0107] Optionally, the variable split heat exchanger 500 is used as an outdoor unit of the air conditioner. When the air conditioner is heating, the variable split heat exchanger 500 is used as an evaporator. Since the variable split heat exchanger 500 adopts the above-mentioned manifold component, the liquid separation of each branch is more uniform, thereby improving the overall performance of the air conditioner.

[0108] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations.
