Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a heat exchanger and an indoor air conditioning unit. Background Technology

[0002] As people's living standards continue to improve, air conditioning has become a common way to regulate indoor temperature in daily life. After an air conditioner has been running for a period of time, a large amount of dust will accumulate on the surface of the heat exchanger of the indoor unit, affecting the heat exchange efficiency and the cleanliness of the air. Therefore, it is necessary to clean the surface of the heat exchanger. How to clean the heat exchanger has become a common problem faced by the industry.

[0003] In related technologies, steam cleaning is used to clean the surface of heat exchangers. An air conditioner indoor unit includes a casing, a heat exchanger, and refrigerant piping. The casing houses the heat exchanger and refrigerant piping. The heat exchanger has fixedly connected fin assemblies and heat exchange tubes, which are connected to the refrigerant piping. Steam cleaning of the heat exchanger surface requires either complete disassembly of the heat exchanger or cleaning without disassembly.

[0004] However, the disassembly and assembly of the heat exchanger involves the discharge and refilling of refrigerant, as well as the disassembly and assembly of the heat exchanger and refrigerant piping. Without disassembly, the heat exchanger is difficult to clean thoroughly because it is partially obscured by the outer casing. Therefore, the heat exchanger in this technology faces the problem of high cleaning difficulty, which urgently needs to be addressed. Summary of the Invention

[0005] This application discloses a heat exchanger and an indoor air conditioning unit, and the heat exchanger is relatively easy to clean.

[0006] To achieve the above objectives, this application discloses a heat exchanger, comprising:

[0007] A heat exchange tube, comprising a bent section and two straight sections, the two straight sections being respectively connected to both ends of the bent section; and

[0008] A fin assembly has a first end and a second end disposed opposite to each other, the fin assembly having a channel extending from the first end to the second end, and the extension direction of the heat exchange tube being the same as the extension direction of the channel.

[0009] The fin assembly includes:

[0010] Multiple fins, each fin having a through hole;

[0011] At least two end plates, wherein the at least two end plates are located at the first end and the second end, respectively;

[0012] A support member, wherein the support member is sequentially disposed through the through holes of the plurality of fins, and the support member is provided with the channel;

[0013] Each of the channels has a length direction and a width direction. ；

[0014] Along the length of the through hole, the through hole has a first dimension A, the channel has a second dimension B, and the heat exchange tube has a third dimension C, where C≤B≤A.

[0015] Straight pipe sections are connected to both ends of the bend in the heat exchange tube. The support has a channel and passes through the through holes of multiple fins in the fin assembly. The channel passes through the two opposite first and second ends of the fin assembly. Along the length of the through hole, the first dimension A of the through hole, the second dimension B of the channel, and the third dimension C of the heat exchange tube are set to C≤B≤A. This allows the bend to pass through the channel from the first end to the second end, enabling two straight pipe sections to pass through the channel. Conversely, when the bend passes through the channel from the second end to the first end, it allows two straight pipe sections to exit the channel.

[0016] Therefore, when cleaning the fin assembly is required, it can be moved from the straight tube section to the curved tube section. Since the movement is relative, the curved tube section can then move from the second end through the channel to the first end, allowing the two straight tube sections to exit the channel, thus separating the fin assembly from the heat exchange tubes. After cleaning, the fin assembly can be moved so that the channel aligns with the curved tube section and the first end of the fin assembly faces the curved tube section. Then, the fin assembly can be moved from the curved tube section to the straight tube section. Again, since the movement is relative, the curved tube section can then move from the first end through the channel to the second end, allowing the two straight tube sections to pass through the channel, thus assembling the fin assembly and heat exchange tubes. The disassembly and assembly of the fin assembly is relatively easy, allowing for efficient and quick disassembly and cleaning, followed by reassembly, thus reducing the overall cleaning difficulty of the heat exchanger.

[0017] On the other hand, this application discloses a heat exchanger, comprising:

[0018] A heat exchange tube, comprising a bent section and two straight sections, the two straight sections being respectively connected to both ends of the bent section; and

[0019] A fin assembly has a first end and a second end disposed opposite to each other, the fin assembly having a channel extending from the first end to the second end, and the extension direction of the heat exchange tube being the same as the extension direction of the channel.

[0020] The fin assembly includes:

[0021] Multiple fins, each fin having a through hole;

[0022] At least two end plates, wherein the at least two end plates are located at the first end and the second end, respectively;

[0023] A support member is sequentially disposed through the through holes of the plurality of fins. The support member is provided with the channel, which is configured to allow the bent pipe segment to pass through from the first end to the second end, so that two straight pipe segments pass through the channel, and to allow the bent pipe segment to pass through from the second end to the first end, so that two straight pipe segments exit the channel.

[0024] Straight pipe sections are connected to both ends of the bend in the heat exchange tube. The support is provided with a channel that passes through the first and second opposite ends of the fin assembly. The channel is configured to allow the bend to pass through from the first end to the second end and from the second end to the first end. Simultaneously, when the bend passes through from the first end to the second end, two straight pipe sections can be inserted into the channel, and when the bend passes through from the second end to the first end, two straight pipe sections can exit the channel.

[0025] Therefore, when cleaning the fin assembly is required, it can be moved from the straight tube section to the curved tube section. Since the movement is relative, the curved tube section can then move from the second end through the channel to the first end, allowing the two straight tube sections to exit the channel, thus separating the fin assembly from the heat exchange tubes. After cleaning, the fin assembly can be moved so that the channel aligns with the curved tube section and the first end of the fin assembly faces the curved tube section. Then, the fin assembly can be moved from the curved tube section to the straight tube section. Again, since the movement is relative, the curved tube section can then move from the first end through the channel to the second end, allowing the two straight tube sections to pass through the channel, thus assembling the fin assembly and heat exchange tubes. The disassembly and assembly of the fin assembly is relatively easy, allowing for efficient and quick disassembly and cleaning, followed by reassembly, thus reducing the overall cleaning difficulty of the heat exchanger.

[0026] In some embodiments of this application, the plurality of fins have an air inlet side and an air outlet side;

[0027] The support member has a first side near the air inlet side and a second side near the air outlet side;

[0028] The support member has a first avoidance window and a second avoidance window arranged opposite to each other, the first avoidance window and the second avoidance window being located on the first side and the second side, respectively.

[0029] The first clearance window connects to the channel, allowing air to enter the channel directly from the inlet side of the multiple fins and exchange heat with the straight pipe section within the channel. The second clearance window connects to the channel again, allowing air to exit the channel after heat exchange with the straight pipe section and flow out from the outlet side of the multiple fins. This design increases the airflow path through the heat exchanger and reduces obstruction of airflow by the support components, thereby lowering the air resistance as the air flows through the heat exchanger.

[0030] In some embodiments of this application, there are multiple first avoidance windows, and the multiple first avoidance windows are arranged at intervals along the extension direction of the channel;

[0031] There are multiple second avoidance windows, and the multiple second avoidance windows are arranged at intervals along the extension direction of the channel, and the multiple second avoidance windows are set opposite to the multiple first avoidance windows.

[0032] By setting multiple first clearance windows, when air enters the gap between multiple fins from the air inlet side, it can enter the channel from multiple positions, improving the efficiency of air entering the channel and exchanging heat directly with the straight pipe section in the channel. By setting multiple second clearance windows, after the air enters the channel and exchanges heat with the straight pipe section in the channel, it can flow out of the channel from multiple positions, improving the efficiency of air flowing out of the channel after exchanging heat with the straight pipe section in the channel.

[0033] In some embodiments of this application, there is a gap between the straight pipe section and the inner wall of the channel.

[0034] By creating a gap between the straight pipe section and the inner wall of the channel, the size of the straight pipe section is smaller than the size of the channel. When the straight pipe section is inserted into or separated from the channel, this gap can provide a certain amount of swaying space for the straight pipe section to move along the extension direction of the channel. This avoids the straight pipe section from being tilted in the extension direction of the channel and interfering with the hole wall of the channel during the assembly and disassembly of the fin assembly, thus preventing them from seizing up and reducing the difficulty of assembly and disassembly.

[0035] In some embodiments of this application, the gap is filled with a thermally conductive material.

[0036] By filling the gaps with thermally conductive material, the thermal conductivity of the straight pipe section and the inner wall of the channel can be improved without affecting the assembly and disassembly of the fin assembly, thereby increasing the heat exchange efficiency. Furthermore, when the filling thermally conductive material has a lubricating effect, the assembly and disassembly difficulty of the fin assembly can be further reduced.

[0037] In some embodiments of this application, the dimension of the support member along the extending direction is larger than the dimension of the fin assembly along the extending direction;

[0038] At least two of the end plates include:

[0039] A first end plate is disposed at one end of the support member;

[0040] The second end plate is located at the end of the support member away from the first end plate.

[0041] By detaching and connecting the first end plate and the second end plate to the outer casing of the target installation equipment, the fin assembly and heat exchange tube are assembled. The connection between the first end plate and the outer casing of the target installation equipment can fix the relative position of the fin assembly and the heat exchange tube. When disassembling the fin assembly from the heat exchange tube, the connection between the first end plate and the outer casing of the target installation equipment can be released, allowing the fin assembly to be detached from the heat exchange tube.

[0042] In some embodiments of this application, the heat exchanger includes a plurality of the fin assemblies arranged along the extension direction of the straight pipe section.

[0043] By arranging multiple finned assemblies along the extension direction of the straight pipe section, multiple finned assemblies can be assembled and disassembled separately during assembly and disassembly. The overall volume of each finned assembly is small, and the difficulty of assembling and disassembling them individually is low.

[0044] On another front, this application discloses an indoor air conditioning unit, comprising:

[0045] The outer casing forms an inner cavity;

[0046] A fan, wherein the fan is disposed within the inner cavity;

[0047] A heat exchange assembly disposed within the inner cavity;

[0048] The heat exchange assembly includes:

[0049] A refrigerant inlet pipe is disposed within the inner cavity;

[0050] A refrigerant outlet pipe is disposed in the inner cavity;

[0051] The heat exchanger is disposed in the inner cavity and is connected to the refrigerant outlet pipe and the refrigerant inlet pipe;

[0052] The heat exchanger is the heat exchanger described in one or the other of the above description.

[0053] Because heat exchangers are relatively easy to clean, when an air conditioner indoor unit includes a heat exchanger, the cleaning difficulty of the indoor unit is reduced, resulting in a better user experience.

[0054] In some embodiments of this application, the fin assembly of the heat exchanger is detachably connected to the housing.

[0055] The finned assembly of the heat exchanger is detached from the outer casing of the indoor unit of the air conditioner. After assembling the finned assembly with the heat exchange tubes, the connection between the finned assembly and the outer casing of the indoor unit of the air conditioner can fix the relative position of the finned assembly and the heat exchange tubes. When disassembling the finned assembly from the heat exchange tubes, the connection between the finned assembly and the outer casing of the indoor unit of the air conditioner can be released, and the finned assembly can be detached from the heat exchange tubes.

[0056] In some embodiments of this application, when the fin assembly includes a first end plate, the first end plate is detachably connected to the housing;

[0057] When the fin assembly includes a second end plate, the second end plate is detachably connected to the housing.

[0058] By detaching and connecting the first end plate and the second end plate to the outer casing of the indoor unit, the fin assembly and heat exchange tube are assembled. The connection between the first end plate and the outer casing of the indoor unit fixes the relative position of the fin assembly and the heat exchange tube. When disassembling the fin assembly and heat exchange tube, the connection between the first end plate and the outer casing of the indoor unit can be released, allowing the fin assembly to be detached from the heat exchange tube.

[0059] In some embodiments of this application, the fin assembly is detachably connected to the housing in one or more of the following ways: snap-fit ​​connection, threaded connection, and magnetic connection.

[0060] The fin assembly and the housing can be detachably connected through various connection methods, which can be selected according to the actual situation. This embodiment does not make specific limitations on this.

[0061] Compared with the prior art, this application has at least the following beneficial effects:

[0062] In this embodiment, straight pipe sections are connected to both ends of the bent section of the heat exchange tube. The support member is provided with a channel and passes through the through holes of multiple fins of the fin assembly. The channel passes through the two opposite first and second ends of the fin assembly. Along the length direction of the through hole, the first dimension A of the through hole, the second dimension B of the channel, and the third dimension C of the heat exchange tube are set to C≤B≤A, so that when the bent section passes through the channel from the first end to the second end, two straight pipe sections can pass through the channel, and when the bent section passes through the channel from the second end to the first end, two straight pipe sections can pass out of the channel.

[0063] Therefore, when cleaning the fin assembly is required, it can be moved from the straight tube section to the curved tube section. Since the movement is relative, the curved tube section can then move from the second end through the channel to the first end, allowing the two straight tube sections to exit the channel, thus separating the fin assembly from the heat exchange tubes. After cleaning, the fin assembly can be moved so that the channel aligns with the curved tube section and the first end of the fin assembly faces the curved tube section. Then, the fin assembly can be moved from the curved tube section to the straight tube section. Again, since the movement is relative, the curved tube section can then move from the first end through the channel to the second end, allowing the two straight tube sections to pass through the channel, thus assembling the fin assembly and heat exchange tubes. The disassembly and assembly of the fin assembly is relatively easy, allowing for efficient and quick disassembly and cleaning, followed by reassembly, thus reducing the overall cleaning difficulty of the heat exchanger.

Unless otherwise stated, "a plurality of" means two or more.

[0092] Before explaining the technical solution of this application, the inventive concept of this application will be explained first.

[0093] Figure 1 This is a structural schematic diagram of an air conditioner indoor unit 1000 provided in an embodiment of this application. Figure 2 This is a schematic diagram illustrating the connection between a heat exchanger 100 and a refrigerant inlet pipe 300 and a refrigerant outlet pipe 400, as provided in an embodiment of this application. Figure 1 and Figure 2 As shown, the heat exchanger 100 is a device installed on the housing 200 of the indoor unit 1000 of the air conditioner, used to perform heat exchange during the operation of the indoor unit 1000 of the air conditioner, thereby achieving room temperature regulation.

[0094] Normally, the heat exchange tubes 10 of the heat exchanger 100 are connected to the refrigerant inlet pipe 300 and the refrigerant outlet pipe 400 installed on the outer casing 200 of the indoor unit 1000, so that the heat exchange tubes 10 can receive the refrigerant input through the refrigerant inlet pipe 300 and output the refrigerant after heat exchange through the refrigerant outlet pipe 400. Furthermore, when the indoor unit 1000 is running, air needs to flow through the heat exchanger 100 and exchange heat with it, mainly through the fin assembly 20 of the heat exchanger 100, and then through the fin assembly 20 to the heat exchange tubes 10. Thus, after the indoor unit 1000 has been running for a period of time, a large amount of dust will accumulate on the surface of the heat exchanger 100 (especially the surface of the fin assembly 20), affecting the heat exchange efficiency of the heat exchanger 100 and the cleanliness of the air. Therefore, the surface of the heat exchanger 100 needs to be cleaned.

[0095] However, since the heat exchange tube 10 and fin assembly 20 in related technologies are often fixedly connected by welding, tube expansion, or other methods, and the heat exchange tube 10 is connected to the refrigerant inlet pipe 300 and the refrigerant outlet pipe 400, with refrigerant flowing through all three, there are two main methods for cleaning the surface of the heat exchanger 100 using steam flushing in related technologies.

[0096] One method involves completely draining the refrigerant from the heat exchanger tube 10 and the refrigerant inlet pipe 300 and refrigerant outlet pipe 400, then disconnecting the heat exchanger tube 10 from these pipes. This allows for the complete removal of the heat exchanger tube 10 and fin assembly 20 from the outer casing 200 of the indoor unit 1000, enabling comprehensive steam cleaning of the heat exchanger 100's surface. After cleaning, the heat exchanger tube 10 is reconnected to the refrigerant inlet pipe 300 and refrigerant outlet pipe 400, and the entire assembly is reinstalled onto the outer casing 200 of the indoor unit 1000 before refilling with refrigerant. This method requires refrigerant draining and refilling, posing certain safety hazards. Furthermore, the disassembly and reinstallation of the heat exchanger tube 10 and refrigerant inlet pipe 300 and refrigerant outlet pipe 400 increase the difficulty of cleaning the heat exchanger 100.

[0097] Secondly, the panel of the outer casing 200 of the indoor unit 1000 of the air conditioner can be opened, and the filter screen can be removed to expose the heat exchanger 100. In this way, the surface of the heat exchanger 100 can be steam-washed. However, since the heat exchanger 100 is not removed from the outer casing 200, part of the heat exchanger 100 is blocked by the outer casing 200, making it difficult to perform multi-directional steam washing of the heat exchanger 100, which increases the difficulty of cleaning the heat exchanger 100.

[0098] In summary, the heat exchanger 100 in the related technology has the problem of being difficult to clean. Therefore, this application provides a heat exchanger 100 and an air conditioning indoor unit 1000 to solve the above problems.

[0099] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0100] The heat exchanger 100 provided in this application embodiment can have various implementation forms. For example, it can be applied to an outdoor unit of an air conditioner, an indoor unit of an air conditioner 1000, a clothes dryer, a refrigerator, etc. This embodiment does not specifically limit it. Figure 1 This application describes one way of using the heat exchanger 100 provided in this embodiment of the application, which is applied to an indoor air conditioning unit 1000.

[0101] Figure 3 This is a schematic diagram of the structure of a heat exchanger 100 provided in an embodiment of this application.

[0102] In some embodiments, such as Figure 4 As shown, the heat exchanger 100 includes a heat exchange tube 10. The material of the heat exchange tube 10 may include copper, aluminum, copper-aluminum alloy, etc., and the cross-sectional shape of the heat exchange tube 10 may include circular, oval, elliptical, etc. Of course, the heat exchange tube 10 may also be made of other possible materials and the cross-sectional shape may also be other possible shapes; this embodiment does not specifically limit these.

[0103] In some embodiments, the heat exchange tube 10 includes two straight tube sections 11.

[0104] Two straight pipe sections 11 can be connected to the refrigerant inlet pipe 300 and refrigerant outlet pipe 400 of the air conditioner indoor unit 1000, thereby enabling the heat exchange tube 10 to receive and discharge refrigerant. Furthermore, the refrigerant flows within the two straight pipe sections 11, and heat exchange is achieved in the heat exchanger 100 through heat conduction between the straight pipe sections 11 and the fin assembly 20.

[0105] In some embodiments, the heat exchanger 100 includes a plurality of heat exchange tubes 10, which can be connected by connecting one straight pipe section 11 of two different heat exchange tubes 10 through a connector, thereby forming a refrigerant circuit with a longer path between the plurality of heat exchange tubes 10, and one or more of the plurality of heat exchange tubes 10 are connected to the refrigerant inlet pipe 300 and the refrigerant outlet pipe 400.

[0106] Furthermore, the number of heat exchange tubes 10 can be one, two, three, four, five, etc., and this embodiment does not specifically limit the number of heat exchange tubes 10.

[0107] In some embodiments, the heat exchange tube 10 includes a bent section 12. The shape of the bent section 12 may include a semi-circle, a U-shape, etc. Of course, the bent section 12 may also have other possible shapes, which are not specifically limited in this embodiment.

[0108] In some embodiments, two straight pipe sections 11 are respectively connected to the two ends of a bend section 12.

[0109] The two ends of the bend section 12 are connected to two straight pipe sections 11 respectively, so that the refrigerant in one straight pipe section 11 can flow through the bend section 12 to the other straight pipe section 11.

[0110] In some embodiments, such as Figure 5 As shown, the heat exchanger 100 includes a fin assembly 20.

[0111] With the fin assembly 20 having a large surface area, when the air conditioner indoor unit 1000 is running, air flows through the heat exchanger 100, and the fin assembly 20 has a large area in contact with the air, thereby improving the heat exchange efficiency.

[0112] In some embodiments, such as Figure 6 and Figure 7 As shown, the fin assembly 20 is provided with a channel 20a, which passes through the two opposite first ends 20b and second ends 20c of the fin assembly 20.

[0113] The fin assembly 20 is penetrated through channel 20a, which allows the straight pipe section 11 to pass through, thereby enabling the fin assembly 20 to be assembled with the heat exchange tube 10.

[0114] In some embodiments, channel 20a is configured to allow a bent pipe segment 12 to pass through from the second end 20c along channel 20a to the first end 20b, so that two straight pipe segments 11 pass through channel 20a.

[0115] When it is necessary to clean the fin assembly 20, the fin assembly 20 can be moved from the straight pipe section 11 to the bent pipe section 12. Since the movement is relative, the bent pipe section 12 can move from the second end 20c through the channel 20a to the first end 20b, so that the two straight pipe sections 11 can pass through the channel 20a, thereby disassembling and separating the fin assembly 20 from the heat exchange tube 10.

[0116] In some embodiments, the channel 20a is configured to allow a bent pipe section 12 to pass through from the first end 20b to the second end 20c, so that two straight pipe sections 11 pass through the channel 20a.

[0117] After cleaning the fin assembly 20, it can be moved so that the channel 20a is aligned with the bend section 12, with the first end 20b of the channel 20a facing the bend section 12. The fin assembly 20 is then moved from the bend section 12 to the straight section 11. Since the movement is relative, the bend section 12 can then move from the first end 20b through the channel 20a to the second end 20c, allowing the two straight sections 11 to pass through the channel 20a, thus assembling the fin assembly 20 and the heat exchange tube 10. The disassembly and assembly of the fin assembly 20 are relatively easy, enabling efficient and quick disassembly and cleaning, followed by reassembly. This also reduces the overall cleaning difficulty of the heat exchanger 100.

[0118] In some embodiments, two straight pipe sections 11 pass through the same channel 20a, which is configured to allow a bent pipe section 12 to pass through one end of the channel 20a to the other end.

[0119] With two straight pipe sections 11 inserted into the same channel 20a, when the bent pipe section 12 is inserted from one end of the channel 20a to the other end, the two straight pipe sections 11 can move with the bent pipe section 12 and exit the channel 20a, so that the two straight pipe sections 11 are separated from the fin assembly 20, realizing the disassembly and separation of the fin assembly 20 from the heat exchange tube 10, which facilitates the cleaning of the fin assembly 20.

[0120] In some embodiments, the fin assembly 20 includes a plurality of fins 21, which are arranged at intervals.

[0121] With multiple fins 21 arranged at intervals, when the indoor unit 1000 of the air conditioner is running, air flows through the heat exchanger 100. The intervals between the multiple fins 21 allow air to flow through, and the surface of the multiple fins 21 contacts the air for heat exchange, resulting in high heat exchange efficiency.

[0122] In some embodiments, each fin 21 is provided with a through hole 211, and multiple fins 21 are arranged at intervals along the extension direction of the straight pipe section 11.

[0123] In some embodiments, the fin assembly 20 includes a support 22, which is sequentially disposed through through holes 211 of a plurality of fins 21.

[0124] In some embodiments, the support member 22 is provided with a channel 20a.

[0125] Multiple fins 21 are disposed on the support member 22 and are spaced apart along the extension direction of the channel 20a, so that the support member 22 and the multiple fins 21 are connected as a whole, and the support member 22 provides support and positioning for the multiple fins 21. Furthermore, when the bent section of the heat exchange tube 10 enters the channel 20a from one end of the channel 20a and exits to the other end of the channel 20a, so that the bent section 12 drives the two straight sections 11 to pass through the channel 20a, the multiple fins 21 can be assembled with the heat exchange tube 10 along with the support member 22 at the same time, which is easy to assemble and efficient. When removing multiple fins 21 from the heat exchange tube 10, the support member 22 can be moved along the straight tube section 11 toward the bend section 12 of the heat exchange tube 10 and removed from the bend section 12 of the heat exchange tube 10. Multiple fins 21 can be removed from the heat exchange tube 10 at the same time along with the support member 22. The disassembly is less difficult and more efficient, making it easier to remove multiple fins 21 from the heat exchange tube 10 for cleaning. The cleaning is also less difficult.

[0126] In some embodiments, the channel 20a is configured to match the cross-sectional shape of the bend segment 12 so that the bend segment 12 can pass through one end of the channel 20a to the other end of the channel 20a.

[0127] The cross-sectional shapes of the two sections do not necessarily have to be exactly the same; there can be some differences, as long as the bend section 12 can pass through the channel 20a. For example, if the cross-section of the bend section 12 is racetrack-shaped, elliptical, or oval, then the cross-section of the channel 20a can be rectangular, triangular, trapezoidal, etc. Of course, the cross-sections of the channel 20a and the bend section 12 can be exactly the same racetrack-shaped, elliptical, oval, rectangular, triangular, trapezoidal, etc., and this embodiment does not impose specific limitations on this.

[0128] In some embodiments, the channel 20a is configured to match the size of the bend segment 12 so that the bend segment 12 can pass through one end of the channel 20a to the other end of the channel 20a.

[0129] The dimensions may not be exactly the same, and there may be some differences. It is only necessary to ensure that the bend section 12 can pass through the channel 20a.

[0130] In some embodiments, such as Figure 8 As shown, the through hole 211 has a length direction x and a width direction y.

[0131] Among them, such as Figure 8As shown, the length direction x of the through hole 211 specifically refers to the direction of the maximum dimension of the cross-section of the through hole 211, and the width direction y of the through hole 211 specifically refers to the direction of the minimum dimension of the cross-section of the through hole 211. That is, when the fin 21 has multiple through holes 211, the length direction x of each through hole 211 can be the same direction or different directions on the fin 211. The specific direction depends on the arrangement of the through holes 211 on the fin 21. The width direction y of each through hole 211 is the same as above and will not be described again.

[0132] Taking the length direction x as an example, Figure 8 The fin 21 has 5 through holes 211, of which 4 through holes 211 have the same length direction x, and the length direction of the remaining through hole 211 is different from the length direction of the other 4 through holes 211.

[0133] Along the length direction x of the through hole 211, the through hole 211 has a first dimension A, the channel 20a has a second dimension B, and the heat exchange tube 10 has a third dimension C.

[0134] Wherein, the first dimension A refers to the dimension of the through hole 211 along the length direction x, that is, the dimension corresponding to the major axis direction of the racetrack-shaped cross-section of the through hole 211. The second dimension B refers to the dimension of the channel 20a along the length direction x, that is, the dimension corresponding to the major axis direction of the racetrack-shaped cross-section of the channel 20a. The third dimension c refers to the dimension of the heat exchange tube 10 along the length direction x, that is, the farthest distance between the two straight tube sections 11 of the heat exchange tube 10 along the spacing direction.

[0135] In some embodiments, C≤B.

[0136] In some embodiments, C≤A.

[0137] In some embodiments, B≤A.

[0138] Along the length direction x of the through hole 211, the first dimension A of the through hole 211, the second dimension B of the channel 20a, and the third dimension C of the heat exchange tube 10 are set to C≤B≤A, so that when the bent pipe section 12 passes through the channel 20a from the first end 20b to the second end 20c, two straight pipe sections 11 can pass through the channel 20a, and when the bent pipe section 12 passes through the channel 20a from the second end 20c to the first end 20b, two straight pipe sections 11 can pass out of the channel 20a.

[0139] In some embodiments, there is a gap between the straight pipe section 11 and the bore wall of the channel 20a.

[0140] By forming a gap between the straight pipe section 11 and the inner wall of the channel 20a, the size of the straight pipe section 11 is smaller than the size of the channel 20a. When the straight pipe section 11 is inserted into or separated from the channel 20a, the gap can provide a certain amount of swaying space for the straight pipe section 11 to move along the extension direction of the channel 20a. This avoids the straight pipe section 11 from being tilted in the extension direction of the channel 20a and interfering with the inner wall of the channel 20a during the assembly and disassembly of the fin assembly 20, which would cause them to seize up. This reduces the difficulty of assembly and disassembly.

[0141] In some embodiments, the size of the gap may be set to be smaller.

[0142] This can prevent the straight pipe section 11 from being tilted in the extension direction of the channel 20a and interfering with the inner wall of the channel 20a during the assembly and disassembly of the fin assembly 20, thus avoiding the situation where they become stuck together. At the same time, it reduces the impact on heat exchange efficiency caused by the straight pipe section 11 not being able to fully contact the inner wall of the channel 20a, and ensures the highest possible heat exchange efficiency.

[0143] In some embodiments, the gaps are filled with a thermally conductive material. The thermally conductive material may include thermally conductive silicone grease, graphite grease, molybdenum disulfide grease, etc. Of course, other possible materials may be used, and this embodiment does not specifically limit them.

[0144] By filling the gaps with thermally conductive material, the thermal conductivity of the inner walls of the straight pipe section 11 and the channel 20a can be improved without affecting the assembly and disassembly of the fin assembly 20, thereby improving the heat exchange efficiency. Furthermore, when the filled thermally conductive material has a lubricating effect, the assembly and disassembly difficulty of the fin assembly 20 can be further reduced.

[0145] In some embodiments, such as Figures 9 to 11 As shown, the plurality of fins 21 have an air inlet side 21a, which is a space between the plurality of fins 21 for air to enter.

[0146] Air is supplied to the gap between the multiple fins 21 through the air inlet side 21a of the multiple fins 21, and the air can exchange heat with the multiple fins 21.

[0147] In some embodiments, the plurality of fins 21 have an air outlet side 21b, which is used to allow air to flow out of the gap between the plurality of fins 21.

[0148] Air flows out of the gap between the multiple fins 21 through the air outlet side 21b of the multiple fins 21. After the air exchanges heat with the multiple fins 21, it can leave the multiple fins 21.

[0149] In some embodiments, the support member 22 has a first side near the air inlet side 21a, and the first side is provided with a first clearance window 22a, which is connected to the channel 20a.

[0150] When air enters the gap between multiple fins 21 from the air inlet side 21a of the multiple fins 21 through the first clearance window 22a connected to the channel 20a, it can enter the channel 20a through the first clearance window 22a and thus directly exchange heat with the straight pipe section 11 in the channel 20a.

[0151] The shape of the first avoidance window 22a may include a square, a circle, an ellipse, etc. Of course, the shape of the first avoidance window 22a may be other possible shapes, and this embodiment does not specifically limit it.

[0152] Furthermore, the number of the aforementioned second clearance windows 22b can be one, two, three, four, five, etc., and this embodiment does not specifically limit the number of heat exchange tubes 10.

[0153] In some embodiments, the support member 22 has a second side near the air outlet side 21b, the second side being provided with a second clearance window 22b, the second clearance window 22b being connected to the channel 20a.

[0154] The second clearance window 22b connects to the channel 20a. After air enters the channel 20a and exchanges heat with the straight pipe section 11 within the channel 20a, it can flow out of the channel 20a through the second clearance window 22b and exit from the air outlet side 21b of the multiple fins 21. Furthermore, this increases the flow path of air through the heat exchanger 100 and reduces the obstruction of airflow by the support member 22, thereby reducing the wind resistance when air flows through the heat exchanger 100.

[0155] The shape of the second avoidance window 22b may include a square, a circle, an ellipse, etc. Of course, the shape of the second avoidance window 22b may be other possible shapes, and this embodiment does not specifically limit it.

[0156] Furthermore, the number of the aforementioned second clearance windows 22b can be one, two, three, four, five, etc., and this embodiment does not specifically limit the number of heat exchange tubes 10.

[0157] In some embodiments, the second avoidance window 22b is positioned opposite to the first avoidance window 22a.

[0158] When air flows through the heat exchanger 100, it flows from the air inlet side 21a of the multiple fins 21 to the air outlet side 21b. The second clearance window 22b is set opposite to the first clearance window 22a. The air that enters the channel 20a through the first clearance window 22a and flows out through the second clearance window 22b can flow in the original flow direction without changing the air flow direction. The air flows through the heat exchanger 100 relatively smoothly with low wind resistance.

[0159] In some embodiments, there are multiple first avoidance windows 22a, and the multiple first avoidance windows 22a are arranged at intervals along the extension direction of the channel 20a.

[0160] By setting multiple first clearance windows 22a, when air enters the gap between multiple fins 21 from the air inlet side 21a of multiple fins 21, it can enter the channel 20a from multiple positions, thereby improving the efficiency of air entering the channel 20a and exchanging heat directly with the straight pipe section 11 in the channel 20a.

[0161] Furthermore, without affecting the structural strength requirements of the support member 22, the first clearance window 22a can achieve a weight reduction design for the support member 22.

[0162] In some embodiments, there are multiple second avoidance windows 22b, and the multiple second avoidance windows 22b are arranged at intervals in the extension direction of the channel 20a.

[0163] By setting multiple second clearance windows 22b, after the air enters the channel 20a and exchanges heat with the straight pipe section 11 in the channel 20a, it can flow out of the channel 20a from multiple positions, thereby improving the efficiency of the air flowing out of the channel 20a after exchanging heat with the straight pipe section 11 in the channel 20a.

[0164] Furthermore, without affecting the structural strength requirements of the support member 22, the second clearance window 22b can achieve a weight reduction design for the support member 22.

[0165] In some embodiments, a plurality of second avoidance windows 22b are disposed opposite to a plurality of first avoidance windows 22a.

[0166] When air flows through the heat exchanger 100, it flows from the air inlet side 21a of the multiple fins 21 to the air outlet side 21b. The air is set opposite to the multiple first clearance windows 22a through multiple second clearance windows 22b. The air that enters the channel 20a at multiple positions and flows out at multiple positions can flow in the original flow direction without changing the air flow direction. The air flows through the heat exchanger 100 relatively smoothly with low wind resistance.

[0167] Furthermore, the structural strength of each part of the support 22 is relatively balanced, which can avoid stress concentration under load and thus prevent damage to the support 22, thereby extending the service life of the support 22.

[0168] In some embodiments, the dimension of the support member 22 along the extension direction is greater than the dimension of the fin assembly 20 along the extension direction.

[0169] In some embodiments, the two ends of the support member 22 protrude from a plurality of fins 21 along the extension direction of the channel 20a.

[0170] Multiple fins 21 protrude from both ends of the support member 22, which can be directly or indirectly connected to the outer casing 200 of the indoor unit 1000, thereby fixing the fin assembly 20 to the outer casing 200. Furthermore, since the heat exchange tube 10 is connected to the refrigerant inlet and outlet pipes of the indoor unit 1000, and the relative position of the heat exchange tube 10 to the outer casing 200 is fixed, the direct or indirect connection of the support member 22 to the outer casing 200 of the indoor unit 1000 further fixes the relative position of the fin assembly 20 to the heat exchange tube 10, achieving positioning of the fin assembly 20 and improving the assembly accuracy of the fin assembly 20.

[0171] In some embodiments, such as Figure 7 As shown, the fin assembly 20 also includes a first end plate 23, which is disposed at one end of the support member 22 and is used for detachable connection with the housing 200 of the target installation equipment.

[0172] By detaching and connecting the first end plate 23 to the housing 200 of the target installation equipment, the fin assembly 20 and the heat exchange tube 10 are assembled. The connection between the first end plate 23 and the housing 200 of the target installation equipment can fix the relative position of the fin assembly 20 and the heat exchange tube 10. When disassembling the fin assembly 20 and the heat exchange tube 10, the connection between the first end plate 23 and the housing 200 of the target installation equipment can be released, and the fin assembly 20 can be detached from the heat exchange tube 10.

[0173] The first end plate 23 can be plate-shaped, block-shaped, boss-shaped, etc. Of course, the first end plate 23 can be other possible shapes, and this embodiment does not specifically limit it.

[0174] The target installation equipment refers to the equipment to which the heat exchanger 100 is applied, and the heat exchanger 100 is installed on the target installation equipment for use. The target installation equipment may be an outdoor unit of an air conditioner, an indoor unit of an air conditioner 1000, a clothes dryer, a refrigerator, etc., but this embodiment does not specifically limit it.

[0175] In some embodiments, the fin assembly 20 further includes a second end plate 24, which is disposed at the end of the support 22 away from the first end plate 23, and is used for detachable connection with the housing 200 of the target mounting device.

[0176] The fin assembly 20 and the heat exchange tube 10 are detached and connected to the housing 200 of the target installation equipment via the second end plate 24. After assembly, the connection between the second end plate 24 and the housing 200 of the target installation equipment can fix the relative position of the fin assembly 20 and the heat exchange tube 10. When disassembling the fin assembly 20 and the heat exchange tube 10, the connection between the second end plate 24 and the housing 200 of the target installation equipment can be released, and the fin assembly 20 can be detached from the heat exchange tube 10.

[0177] The second end plate 24 can be plate-shaped, block-shaped, boss-shaped, etc. Of course, the second end plate 24 can be other possible shapes, and this embodiment does not specifically limit it.

[0178] In some embodiments, the heat exchanger 100 includes a plurality of fin assemblies 20 arranged along the extension direction of the straight pipe section 11.

[0179] By arranging multiple finned assemblies 20 along the extension direction of the straight pipe section 11, the multiple finned assemblies 20 can be assembled and disassembled separately during assembly and disassembly. The overall volume of each finned assembly 20 is small, and the difficulty of assembling and disassembling them individually is low.

[0180] The number of the aforementioned finned assemblies 20 can be one, two, three, four, five, etc. In this embodiment, the number of heat exchange tubes 10 is not specifically limited.

[0181] This application embodiment also provides an air conditioner indoor unit 1000. In some embodiments, as shown in 1, the air conditioner indoor unit 1000 includes: a housing 200, the housing 200 forming an inner cavity.

[0182] The inner cavity can be cylindrical or cuboid in shape, etc. Of course, the inner cavity can be other possible shapes, and this embodiment does not limit them.

[0183] In some embodiments, the indoor unit 1000 of the air conditioner includes a heat exchange assembly disposed in an inner cavity.

[0184] By installing a heat exchange component in the inner cavity, the air conditioner indoor unit 1000 can exchange heat by flowing through the heat exchange component during operation, thereby changing the temperature of the air.

[0185] In some embodiments, the indoor unit 1000 of the air conditioner includes a fan disposed in an inner cavity.

[0186] By installing a fan in the inner cavity, the fan can quickly blow the air that has undergone heat exchange in the inner cavity to the room where the air conditioner indoor unit 1000 is located, resulting in better cooling effect of the air conditioner indoor unit 1000.

[0187] In some embodiments, the heat exchange assembly includes a refrigerant inlet pipe 300 disposed in the inner cavity.

[0188] By installing a refrigerant inlet pipe 300 in the inner cavity, refrigerant can be introduced to achieve heat exchange with the air.

[0189] In some embodiments, the heat exchange assembly includes a refrigerant outlet pipe 400 disposed in the inner cavity.

[0190] By installing a refrigerant outlet pipe 400 in the inner cavity, the refrigerant inlet pipe 300 can discharge the refrigerant after heat exchange with the air.

[0191] In some embodiments, the heat exchange assembly includes a heat exchanger 100 disposed in an inner cavity.

[0192] By installing a heat exchanger 100 in the inner cavity, when the air conditioner indoor unit 1000 is running, air can flow through the heat exchanger 100 to exchange heat, thereby changing the temperature of the air.

[0193] In some embodiments, the refrigerant inlet pipe 300 is connected to the heat exchanger 100, and the refrigerant outlet pipe 400 is connected to the heat exchanger 100.

[0194] Refrigerant is introduced into heat exchanger 100 through refrigerant inlet pipe 300. When air flows through heat exchanger 100, the air exchanges heat with refrigerant through heat exchanger 100, thereby changing the temperature of the air. After the refrigerant exchanges heat with the air in heat exchanger 100, it can be discharged through refrigerant outlet pipe 400.

[0195] The structure of the heat exchanger 100 can be the same as that of any of the heat exchangers 100 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the heat exchanger 100 in the above embodiments. This embodiment will not repeat the description here.

[0196] In some embodiments, the fin assembly 20 of the heat exchanger 100 is detachably connected to the housing 200.

[0197] The fin assembly 20 of the heat exchanger 100 is detached from the outer casing 200 of the indoor unit 1000. After assembling the fin assembly 20 with the heat exchange tube 10, the connection between the fin assembly 20 and the outer casing 200 of the indoor unit 1000 can fix the relative position of the fin assembly 20 and the heat exchange tube 10. When disassembling the fin assembly 20 from the heat exchange tube 10, the fin assembly 20 can be detached from the heat exchange tube 10 by disconnecting the fin assembly 20 from the outer casing 200 of the indoor unit 1000.

[0198] In some embodiments, the fin assembly 20 and the housing 200 are detachably connected by one or more of the following methods: snap-fit ​​connection, threaded connection, and magnetic connection. Of course, other possible connection methods may be used for the detachable connection between the fin assembly 20 and the housing 200, and this embodiment does not specifically limit them.

[0199] In this embodiment, since the heat exchanger 100 is relatively easy to clean, when the air conditioner indoor unit 1000 includes the heat exchanger 100, the air conditioner indoor unit 1000 is easier to clean and provides a better user experience.
