[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0045] This disclosure provides an air conditioning system, including a heat exchanger 100. For example... Figure 1 As shown, the heat exchanger 100 includes at least a first heat exchange module 110 and a second heat exchange module 120. The first heat exchange module 110 includes a first heat exchange branch group 111 and a first flow path switching component. The first heat exchange branch group 111 includes multiple heat exchange branches. The first flow path switching component is disposed in the first heat exchange branch group 111 and is used to switch the connection mode of at least some of the different heat exchange branches in the first heat exchange branch group 111 under different operating modes. The first heat exchange module 110 and / or the second heat exchange module 120 include manifold components.
[0046] In this embodiment, the heat exchanger 100 includes at least two heat exchange modules, namely a first heat exchange module 110 and a second heat exchange module 120. Thus, in scenarios where the heat exchanger 100 has a long flow path and many branches, by setting multiple heat exchange modules, the number of heat exchange tubes in a single heat exchange module is not too large, which is beneficial to the uniformity of refrigerant distribution in each heat exchange module of the heat exchanger 100, thereby improving the heat exchange capacity of the heat exchanger 100.
[0047] Furthermore, the first flow path switching component is used to switch the connection mode of at least some of the different heat exchange branches in the first heat exchange branch group 111 under different operating modes. For example, when the air conditioning system is operating in cooling mode and the outdoor heat exchanger 100 acts as a condenser, multiple heat exchange branches in the first heat exchange branch group 111 are connected in series. When the air conditioning system is operating in heating mode and the outdoor heat exchanger 100 acts as an evaporator, multiple heat exchange branches in the first heat exchange branch group 111 are connected in parallel. In this way, the first flow path switching component ensures that the heat exchanger 100 has an optimal flow path in different operating modes, that is, it has a variable flow splitting function, effectively improving the heat exchange efficiency of the heat exchanger 100.
[0048] like Figure 2As shown, taking the first heat exchange module 110 as an example, the first heat exchange module 110 includes a first manifold component 130 and a second manifold component 140. The first flow path switching assembly includes a first conductive component 131 and a second conductive component 141, with the first conductive component 131 disposed on the first manifold component 130 and the second conductive component 141 disposed on the second manifold component 140. The first heat exchange branch group 111 includes a first heat exchange branch 111, a second heat exchange branch 112, and a third heat exchange branch 113. The first end of the first heat exchange branch 111 is connected to the upstream of the first conductive component 131, and the second end of the first heat exchange branch 111 is connected to the upstream of the second conductive component 141. The first end of the second heat exchange branch 112 is connected to the downstream of the first conductive component 131, and the second end of the second heat exchange branch 112 is connected to the upstream of the second conductive component 141. The first end of the third heat exchange branch 113 is connected to the downstream of the first conductive component 131, and the second end of the third heat exchange branch 113 is connected to the downstream of the second conductive component 141. It should be noted that the upstream and downstream concepts of the first conductive component 131 and the second conductive component 141 are based on the flow direction when the heat exchanger 100 is used as an evaporator. Furthermore, the first heat exchange module 110 may have 4, 5, 6, or more heat exchange branches, which will not be listed here.
[0049] When heat exchanger 100 is used as a condenser, such as Figure 2 As shown in (a), the refrigerant enters the heat exchanger 100 through the second manifold assembly 140, while the first and second conductive components 131 and 141 block the flow. At this time, the refrigerant flows sequentially along the third heat exchange branch 113, the second heat exchange branch 112, and the first heat exchange branch 111 connected in series to the inlet and outlet of the first manifold assembly 130, and finally exits the heat exchanger 100. When the heat exchanger 100 functions as an evaporator, as... Figure 2 As shown in (b), the refrigerant enters the heat exchanger 100 through the first manifold component 130, and the first conductive component 131 and the second conductive component 141 are connected. At this time, the refrigerant flows along the parallel first heat exchange branch 111, the second heat exchange branch 112 and the third heat exchange branch 113 to the inlet and outlet of the second manifold component 140, and finally flows out of the heat exchanger 100.
[0050] In the case where the air conditioning system is in heating mode and the outdoor heat exchanger 100 acts as an evaporator, the refrigerant enters the heat exchanger 100 through the first manifold component 130. Since multiple heat exchange branches are connected to the first manifold component 130, the flow distribution within the first manifold component 130 and the uniformity of the gas-liquid two-phase refrigerant in each heat exchange branch directly affect the performance of the heat exchanger 100. Furthermore, the noise generated when the refrigerant flows through the first flow path switching component also impacts the user experience. The following sections detail improvements to the manifold component in conjunction with the first and second embodiments, and details improvements to the first flow path switching component in conjunction with the third embodiment.
[0051] The first embodiment provides a manifold component with a conductive member, including a main pipe section 200 and a first conductive member 131. For example... Figure 3 As shown, the first conductive component 131 is configurably disposed on the main pipe section 200, dividing the main pipe section 200 into a first pipe section 210 and a second pipe section 220. The first pipe section 210 is provided with a first branch pipe 211, and the second pipe section 220 is provided with a second branch pipe 221. The inner diameter of the first pipe section 210 is w1, and the first conductive component 131 is provided with a first conductive port 231 with a diameter of w2. Therefore, 0.6 ≤ w2 / w1 ≤ 0.85.
[0052] In this embodiment, after the refrigerant enters the main pipe section 200, it flows from the first pipe section 210 to the second pipe section 220, and is subsequently branched through the first branch pipe 211 and the second branch pipe 221. When w2 is less than w1, the refrigerant flowing to the second pipe section 220 via the first conductive component 131 is accelerated, thereby ensuring the refrigerant distribution in the second branch pipe 221. Furthermore, by reasonably setting the value of w2 / w1, excessive pressure loss is prevented. In this way, the refrigerant distribution in the first branch pipe 211 and the second branch pipe 221 is effectively balanced.
[0053] Optionally, the values of w2 / w1 include 0.6, 0.65, 0.7, 0.75, 0.8, or 0.85.
[0054] Optionally, such as Figure 3 As shown, the first conductive component 131 includes a first valve chamber 230 and a first valve core 240. The first valve chamber 230 has a first conductive port 231. The first valve core 240 is movably disposed within the first valve chamber 230. When the refrigerant flows in a first direction, the first valve core 240 avoids the first conductive port 231. When the refrigerant flows in a second direction, the first valve core 240 blocks the first conductive port 231. The first direction is opposite to the second direction. In this embodiment, when the first valve core 240 avoids the first conductive port 231, the refrigerant in the first pipe section 210 can flow from the first conductive port 231 to the second pipe section 220. When the first valve core 240 blocks the first conductive port 231, the refrigerant in the second pipe section 220 cannot flow from the first conductive port 231 to the first pipe section 210. Here, the first conductive component 131 can be considered a one-way valve.
[0055] Optionally, such as Figure 3 As shown, the inner diameter of the second pipe section 220 is w3, and the second pipe section 220 is provided with a constriction structure 222 with a diameter of w4. Therefore, 0.5≤w4 / w3≤0.99. In this way, after the refrigerant enters the second pipe section 220 from the first pipe section 210, it has an acceleration effect when flowing through the constriction structure 222.
[0056] Optionally, the values of w4 / w3 include 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or 0.99.
[0057] Optionally, multiple second branch pipes 221 are provided along the extension direction of the second pipe segment 220, wherein the constriction structure 222 is located upstream of the last second branch pipe 221 in the extension direction. Since there are multiple second branch pipes 221, the last second branch pipe 221 experiences a lower flow rate due to refrigerant distribution. Therefore, by placing the constriction structure 222 at the aforementioned position, it is beneficial to ensure the flow rate of the last second branch pipe 221.
[0058] Optionally, multiple second branch pipes 221 are provided along the extension direction of the second pipe section 220, and a constriction structure 222 is provided between every two adjacent second branch pipes 221. In this way, by setting multiple constriction structures 222, the refrigerant flowing through is accelerated multiple times, thereby ensuring the flow rate of the multiple second branch pipes 221.
[0059] Optionally, the inner diameter of the second pipe section 220 is w3, and w3 = w1. In this way, the first pipe section 210 and the second pipe section 220 use the same diameter, which helps to reduce production costs and facilitates rapid assembly.
[0060] The first embodiment also discloses a heat exchanger 100, which includes at least a first heat exchange module 110 and a second heat exchange module 120. The first heat exchange module 110 includes a first heat exchange branch group 111 and a first flow path switching component. The first heat exchange branch group 111 includes multiple heat exchange branches. The first flow path switching component is disposed in the first heat exchange branch group 111 and is used to switch the connection mode of at least some different heat exchange branches in the first heat exchange branch group 111 under different operating modes. The first heat exchange module 110 and / or the second heat exchange module 120 include the aforementioned manifold member with a conductive component. Thus, under the action of the first conductive component 131, the refrigerant distribution of the first branch pipe 211 and the second branch pipe 221 is effectively balanced, thereby improving the heat exchange effect of the heat exchanger 100. The structure of the heat exchanger 100 is detailed above.
[0061] The first embodiment also provides an air conditioning system, including the heat exchanger 100 described above.
[0062] The second embodiment provides a manifold component with a filter assembly, including a first connecting pipe 310 and a second connecting pipe 320. The inner diameter of the first connecting pipe 310 is d1. The first end of the second connecting pipe 320 is connected to the first end of the first connecting pipe 310, and its inner diameter is d2. A limiting structure is provided at the connection point of the first connecting pipe 310 and the second connecting pipe 320. The filter assembly is disposed within the first connecting pipe 310 and the second connecting pipe 320, including a base 300 and a filter screen 301. The base 300 is mounted on the limiting structure, and the filter screen 301 is mounted on the base 300. Where d1 > d2, or d1 < d2.
[0063] In this embodiment, the filter assembly is installed within the manifold assembly via a base 300 and a limiting structure. When the gas-liquid two-phase refrigerant flows through the filter screen 301, the liquid and gaseous refrigerants are dispersed and thoroughly mixed. Furthermore, the inner diameters of the first connecting pipe 310 and the second connecting pipe 320 are different. When the refrigerant flows from the larger inner diameter to the smaller inner diameter, the increased flow velocity through the filter screen 301 enhances the filtration effect; conversely, when the refrigerant flows from the smaller inner diameter to the larger inner diameter, the decreased flow velocity reduces the pressure on the filter screen 301 and extends its service life. Thus, the uniformity of gas-liquid mixing is effectively improved by the filter assembly.
[0064] Optionally, such as Figure 4 As shown, when d1 < d2, the first end of the first connecting pipe 310 is provided with a flared section 311, and the first end of the second connecting pipe 320 extends into the flared section 311. Furthermore, the diameter of the base 300 is adapted to the inner diameter of the flared section 311. In this embodiment, the first connecting pipe 310 and the second connecting pipe 320 are separately disposed, and the outer wall of the first end of the second connecting pipe 320 abuts against the inner wall of the flared section 311, while the side of the base 300 abuts against the inner wall of the flared section 311.
[0065] Optionally, such as Figure 4 As shown, the limiting structure includes a first limiting part 330 and a second limiting part 340. The diameter change point of the flared section 311 serves as the first limiting part 330. The edge of the first end of the second connecting pipe 320 serves as the second limiting part 340. The side of the base 300 facing the first connecting pipe 310 abuts against the first limiting part 330, and the side of the base 300 facing the second connecting pipe 320 abuts against the second limiting part 340. In this embodiment, the filter assembly is installed on the flared section 311. With the first connecting pipe 310 and the second connecting pipe 320 arranged vertically, the filter screen 301 faces the second connecting pipe 320. Furthermore, the top surface of the base 300 is limited by the diameter change point of the flared section 311, and the bottom surface of the base 300 is limited by the edge of the first end of the second connecting pipe 320.
[0066] Optionally, such as Figure 5 As shown, when d1 > d2, the first end of the first connecting pipe 310 is provided with a constricted section 312, and the first end of the second connecting pipe 320 extends into the constricted section 312. Furthermore, the diameter of the base 300 is adapted to the inner diameter of the constricted section 312. In this embodiment, the first connecting pipe 310 and the second connecting pipe 320 are separately disposed, and the outer wall of the first end of the second connecting pipe 320 abuts against the inner wall of the constricted section 312, while the side of the base 300 abuts against the inner wall of the constricted section 312.
[0067] Optionally, such as Figure 5 As shown, the limiting structure includes a first limiting part 330 and a second limiting part 340. A narrowing protrusion 313 is provided at the diameter change of the narrowing section 312, serving as the first limiting part 330. The edge of the first end of the second connecting pipe 320 serves as the second limiting part 340. The side of the base 300 facing the first connecting pipe 310 abuts against the first limiting part 330, and the side of the base 300 facing the second connecting pipe 320 abuts against the second limiting part 340. In this embodiment, the filter assembly is installed on the narrowing section 312. With the first connecting pipe 310 and the second connecting pipe 320 arranged vertically, the filter screen 301 faces the second connecting pipe 320. Furthermore, the top surface of the base 300 is limited by the narrowing protrusion 313, and the bottom surface of the base 300 is limited by the edge of the first end of the second connecting pipe 320.
[0068] Optionally, such as Figure 6 As shown, when d1 > d2, a limiting sleeve 350 is provided between the outer wall of the first end of the second connecting pipe 320 and the inner wall of the first end of the first connecting pipe 310. The limiting structure includes a first limiting part 330 and a second limiting part 340. The limiting sleeve 350 serves as the first limiting part 330, and the edge of the first end of the second connecting pipe 320 serves as the second limiting part 340. The side of the base 300 facing the first connecting pipe 310 abuts against the first limiting part 330, and the side of the base 300 facing the second connecting pipe 320 abuts against the second limiting part 340. In this embodiment, the first connecting pipe 310 and the second connecting pipe 320 are separately arranged. When the first connecting pipe 310 and the second connecting pipe 320 are arranged vertically, the filter screen 301 faces the second connecting pipe 320. Furthermore, the top surface of the base 300 is limited by the limiting sleeve 350, and the bottom surface of the base 300 is limited by the edge of the first end of the second connecting pipe 320. By setting the limiting sleeve 350, the sealing between the first connecting pipe 310 and the second connecting pipe 320 can be improved, and the base 300 can also be limited.
[0069] Optionally, such as Figure 7As shown, the first connecting pipe 310 and the second connecting pipe 320 are integrally formed. The limiting structure includes a first limiting part 330 and a second limiting part 340. The first limiting part 330 is formed by protruding from the inner wall of the first connecting pipe 310. The second limiting part 340 is formed by protruding from the inner wall of the second connecting pipe 320. The side of the base 300 facing the first connecting pipe 310 abuts against the first limiting part 330, and the side of the base 300 facing the second connecting pipe 320 abuts against the second limiting part 340. In this embodiment, the two connecting pipes are integrally formed into one pipe body, the filter screen 301 faces the second connecting pipe 320, and d1 > d2. When the manifold assembly is arranged vertically, the top surface of the base 300 is limited by the first limiting part 330, and the bottom surface of the base 300 is limited by the second limiting part 340.
[0070] Optionally, such as Figure 8 As shown, the first connecting pipe 310 and the second connecting pipe 320 are integrally formed. The limiting structure includes a limiting groove 360, which is formed by the inner wall recess at the connection between the first connecting pipe 310 and the second connecting pipe 320, wherein the base 300 is disposed within the limiting groove 360. In this embodiment, the two connecting pipes are integrally formed into one pipe body, with the filter screen 301 facing the second connecting pipe 320. Furthermore, the base 300 is embedded in the limiting groove 360 on all sides, thereby being effectively fixed and limited.
[0071] The second embodiment also discloses a heat exchanger 100, which includes at least a first heat exchange module 110 and a second heat exchange module 120. The first heat exchange module 110 includes a first heat exchange branch group 111 and a first flow path switching component. The first heat exchange branch group 111 includes multiple heat exchange branches. The first flow path switching component is disposed in the first heat exchange branch group 111 and is used to switch the connection mode of at least some different heat exchange branches in the first heat exchange branch group 111 under different operating modes. The first heat exchange module 110 and / or the second heat exchange module 120 include the aforementioned manifold member with a filter component. Thus, under the action of the filter component, the uniformity of the gas-liquid two-phase refrigerant within the heat exchanger 100 is improved, thereby improving the heat exchange effect of the heat exchanger 100. The structure of the heat exchanger 100 is detailed above.
[0072] The second embodiment also provides an air conditioning system, including the heat exchanger 100 described above.
[0073] The third embodiment of this application provides a valve body structure, including a first valve cavity 230 and a first valve core 240. For example... Figure 10As shown, the first valve chamber 230 has a first through port 231 at its first end, a first impact port 232 at its second end, and a first flow port 233 on its side wall. A first valve core 240 is movably disposed within the first valve chamber 230, with its first end facing the first through port 231 and its second end facing the first impact port 232. The first valve core 240 has a first position that avoids the first through port 231 and a second position that blocks the first through port 231. When the first valve core 240 moves to the first position, the first through port 231 and the first flow port 233 are connected. The first end of a spring member 234 is fixed at the first impact port 232, and its second end extends towards the first valve core 240. Furthermore, the spring member 234 can elastically abut against the first valve core 240 in the first position.
[0074] In this embodiment, when the refrigerant enters the first valve chamber 230 from the first through port 231 in the first direction, the first valve core 240 is pushed open and pushed to the first position. At this time, the refrigerant can continue to flow through the first through port 231 and the first flow port 233 in sequence. Figure 11 As shown in (a). Furthermore, the spring 234 effectively reduces the noise generated when the refrigerant impacts the first valve core 240. When the refrigerant enters the first valve chamber 230 from the first impact port 232 in the second direction, it pushes open the first valve core 240 and pushes it to the second position, at which point the refrigerant cannot continue to flow through the first conduction port 231. Here, the first direction is opposite to the second direction.
[0075] Optionally, such as Figure 10 As shown, the second end of the first valve core 240 is provided with a first receiving groove 245, which corresponds to the spring member 234. Furthermore, when the first valve core 240 moves to the first position, the second end of the spring member 234 abuts against the bottom of the first receiving groove 245, and the groove cover of the first receiving groove 245 is fastened to the first impact port 232.
[0076] In this embodiment, when the refrigerant flows in the first direction, it pushes the first valve core 240 from the first through-port 231. As the first valve core 240 moves, the second end of the spring member 234 extends into the first receiving groove 245 and abuts against its bottom. At this time, the spring member 234 provides elastic damping for the first valve core 240. Simultaneously, the groove cover of the first receiving groove 245 is fastened to the first impact port 232, thus blocking the first impact port 232.
[0077] Optionally, such as Figure 10As shown, the spring element 234 is constructed as a conical spring, and the maximum outer diameter of the conical spring is fixed to the periphery of the first impact port 232. Multiple latches 235 are arranged around the periphery of the first impact port 232 for securing the conical spring. In this embodiment, the conical spring has better elastic properties, and the latches 235 facilitate assembly.
[0078] Optionally, such as Figure 10 As shown, the first valve core 240 includes a first valve section 241 and a second valve section 242. The first valve section 241 is constructed in a cylindrical shape, with its first end facing the first impact port 232. The second valve section 242 is connected to the second end of the first valve section 241 and is constructed in a frustum shape. Furthermore, the top surface of the frustum of the second valve section 242 faces the first through port 231. In this embodiment, when the refrigerant flows in a first direction, the refrigerant directly impacts the second valve section 242 from the first through port 231. Because the second valve section 242 is constructed in a frustum shape, it has a special side profile shape, resulting in a more uniform thrust generated by the refrigerant impact on this side. Furthermore, the first valve section 241 is constructed in a cylindrical shape, providing a reference for movement along its axial direction, which helps improve the stability of the first valve core 240 during movement.
[0079] Optionally, the diameter of the first passage 231 is smaller than the diameter of the first valve cavity 230. The diameter of the first valve section 241 is adapted to the diameter of the first valve cavity 230, and the top surface of the frustum of the second valve section 242 is adapted to the diameter of the first passage 231. In this embodiment, the matching of the diameter of the first valve section 241 to the diameter of the first valve cavity 230 helps to reduce the radial wobble of the first valve core 240. The matching of the top surface of the frustum of the second valve section 242 to the diameter of the first passage 231 helps to seal the first passage 231.
[0080] Optionally, such as Figure 10 As shown, the second valve section 242 has a first stepped surface 243 on its side, and a second stepped surface 244 corresponding to the first stepped surface 243 is provided on the periphery of the inner side of the first guide port 231. Furthermore, when the first valve core 240 moves to the second position, the first stepped surface 243 and the second stepped surface 244 abut against each other to seal the first guide port 231. In this embodiment, when the refrigerant flows in the second direction, the refrigerant pushes the first valve core 240 from the first impact port 232. As the first valve core 240 moves, the first stepped surface 243 abuts against the second stepped surface 244, thereby sealing the first guide port 231. This improves the sealing performance at the first guide port 231.
[0081] The third embodiment also discloses a heat exchanger 100, including the valve body structure described above.
[0082] In some embodiments, such as Figure 2 and Figure 9 As shown, the heat exchanger 100 also includes a first manifold component 130, a second manifold component 140, a first conductive component 131, and a second conductive component 141. The first manifold component 130 has a first inlet and outlet, which are used to connect to a throttling device. The second manifold component 140 has a second inlet and outlet, which are used to connect to a compressor. Furthermore, the first manifold component 130 and the second manifold component 140 are connected by multiple heat exchange branches. The first conductive component 131 is disposed on the first manifold component 130 and includes the aforementioned valve body structure. The second conductive component 141 is disposed on the second manifold component 140 and includes a second valve chamber 260 and a second valve core 270. Figure 12 As shown, the second valve cavity 260 has a second guide port 261 at its first end, a second impact port 262 at its second end, and a second flow port 263 on its side wall. The second valve core 270 is movably disposed within the second valve cavity 260, with its first end facing the second guide port 261 and its second end facing the second impact port 262. The second valve core 270 has a first position that avoids the second guide port 261 and a second position that blocks the second guide port 261. When the second valve core 270 moves to the first position, the second guide port 261 and the second flow port 263 are connected.
[0083] In this embodiment, the first conductive component 131 has a spring element 234, while the second conductive component 141 does not have a spring element 234. When the heat exchanger 100 functions as an evaporator, the refrigerant, after being throttled and depressurized by the throttling device, flows into the first manifold component 130 through the first inlet and outlet. Then, the refrigerant in the first manifold component 130 flows to the second manifold component 140 after heat exchange through multiple heat exchange branches. Finally, the refrigerant in the second manifold component 140 flows to the compressor via the second inlet and outlet.
[0084] Since the first inlet and outlet of the first manifold component 130 are connected to the throttling device, vibration is not transmitted from the throttling device to the first manifold component 130. Therefore, a first conductive component 131 with a spring element 234 is used. When the first valve core 240 is in the second position, the spring element 234 will not wobble even in a free state; when the first valve core 240 is in the first position, it elastically contacts the spring element 234, which effectively reduces the noise generated when the refrigerant impacts the valve core. Since the second inlet and outlet of the second manifold component 140 are connected to the compressor, the compressor vibrates significantly during operation, and this vibration can be transmitted to the second manifold component 140. If the second conductive component 141 is also equipped with a spring element 234, the spring element 234 will generate wobbling noise when in a free state. Therefore, using a second conductive component 141 without a spring element 234 can avoid vibration from the compressor to the spring element 234. In this way, by using a first conductive component 131 with a spring element 234 and a second conductive component 141 without a spring element 234, the noise of the heat exchanger 100 during operation can be effectively reduced.
[0085] Optionally, the second valve chamber 260 has the same structure as the first valve chamber 230, and / or the second valve core 270 has the same structure as the first valve core 240.
[0086] In this embodiment, when the refrigerant enters the second valve chamber 260 from the second guide port 261 in the first direction, the second valve core 270 is pushed open and pushed to the first position. At this time, the refrigerant can continue to flow through the second guide port 261 and the second flow port 263 in sequence. Figure 12 As shown in (a), when the refrigerant enters the second valve chamber 260 from the second impact port 262 in the second direction, it pushes open the second valve core 270 and pushes the second valve core 270 to the second position. At this time, the refrigerant cannot continue to flow through the second conduction port 261, as shown in (a). Figure 12 As shown in (b).
