Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a liquid separator and a heat exchanger. Background Technology

[0002] The main components of an air conditioning system include a compressor, condenser, throttling device, and heat exchanger. The heat exchanger is responsible for exchanging heat with the outside environment. The heat exchanger includes fins, heat exchange tubes, manifolds, and a distributor. The distributor is mainly responsible for evenly distributing the medium.

[0003] The existing distributor includes a sleeve and a distribution plate. One end of the heat exchange tube extends into the sleeve and communicates with the inside of the sleeve. The distribution plate is installed inside the sleeve and has multiple distribution holes. The medium enters the distributor, is distributed through the distribution holes, and then enters the heat exchange tube, thereby achieving a uniform distribution effect.

[0004] However, the medium entering the distributor is usually in the form of a gas-liquid two-phase system. Due to the application conditions and the complexity of gas-liquid two-phase flow, it is difficult for the distribution plate to achieve uniform distribution of the medium. In many cases, when the gas-liquid two-phase medium enters the distributor, the different flow velocities of the gas and liquid will cause flow separation, resulting in uneven mixing of the medium before it enters the heat exchange tubes, which greatly affects the overall performance of the heat exchanger. Summary of the Invention

[0005] Based on this, and in response to the aforementioned technical problems, it is necessary to provide a liquid separator and a heat exchanger that can improve the uniformity of the medium and increase the heat exchange efficiency of the heat exchanger.

[0006] A liquid distributor includes a sleeve, a distribution structure, and a turbulence plate. Multiple heat exchange tubes are threaded through the sleeve. The distribution structure is located inside and connected to the sleeve, and is capable of dividing the interior of the sleeve into at least two interconnected chambers: a first chamber located on the side of the distribution structure away from the heat exchange tubes, and a second chamber located on the side of the distribution structure closer to the heat exchange tubes. The turbulence plate is located inside the second chamber and connected to the sleeve, and is spaced apart from the distribution structure. A portion of the heat exchange tubes is inserted into the turbulence plate and communicates with the second chamber.

[0007] Understandably, the turbulence plate can fill the gap between two adjacent heat exchange tubes, preventing the medium from flowing into the gap, and can reduce the separation space of the gas and liquid two-phase medium. Combined with the distribution structure, it can make the medium mix evenly and distribute it evenly, thereby making the gas and liquid two-phase medium mix more evenly and improving the heat exchange efficiency of the heat exchanger.

[0019] This setting can improve the uniformity of media mixing.

[0020] In one embodiment, the plurality of fillers are arranged in a matrix; or, along the length of the turbulence plate, the plurality of fillers are divided into multiple rows, and in two adjacent rows of fillers, the plurality of fillers in one row are staggered with the plurality of fillers in the other row.

[0021] This setup can further improve the uniformity of media mixing.

[0022] In one embodiment, the filler is a solid of revolution or a polyhedron.

[0023] This configuration increases the contact area of ​​the medium, thereby improving the uniformity of the medium mixing.

The dispensing plate has a plurality of dispensing holes that communicate between the first chamber and the second chamber. The plurality of fillers are located in the first chamber and connected to the dispensing plate. And / or, the plurality of fillers are located in the second chamber and connected to the dispensing plate.

[0027] This setting can improve the uniformity of media mixing.

[0028] In one embodiment, a plurality of fillers are distributed sequentially along the length and width directions of the distribution plate, and adjacent fillers are connected to each other to form a plate-like structure; wherein at least one liquid equalization hole is formed between the plurality of fillers.

[0029] This design improves the uniformity of media mixing and increases the structural stability of the distributor.

[0030] In one embodiment, the plurality of fillers are arranged in a matrix; or, along the length of the distribution plate, the plurality of fillers are divided into multiple rows, and in two adjacent rows of fillers, the plurality of fillers in one row are staggered with the plurality of fillers in the other row.

[0031] This setup can further improve the uniformity of media mixing.

[0055] Please see Figure 1 This application provides a liquid distributor 10, which is applied to a heat exchanger 100.

[0056] The main components of an air conditioning system include a compressor, a condenser, a throttling device, and a heat exchanger. The heat exchanger is responsible for exchanging heat with the outside environment. The heat exchanger includes heat exchange tubes, a manifold, and a distributor inserted from one end of the manifold. The distributor is mainly responsible for evenly distributing the medium.

[0057] Existing distributors include a sleeve and a distribution plate. One end of the heat exchange tube extends into the sleeve and communicates with its interior. The distribution plate is installed inside the sleeve and has multiple distribution holes. The medium enters the distributor, is distributed through the distribution holes, and then enters the heat exchange tube, achieving a uniform distribution. However, the medium entering the distributor is usually in a gas-liquid two-phase form. Due to application conditions and the complexity of gas-liquid two-phase flow, the distribution plate struggles to achieve uniform medium distribution. In many cases, when the gas-liquid two-phase medium enters the distributor, the different flow velocities of the gas and liquid cause flow separation, resulting in uneven mixing before the medium enters the heat exchange tube, significantly affecting the overall performance of the heat exchanger.

[0058] To resolve the above issues, please refer to Figure 1 and Figure 6This application provides a liquid distributor 10, which includes a sleeve 11, a distribution structure 12, and a turbulence plate 15. A plurality of heat exchange tubes 20 are inserted through the sleeve 11. The distribution structure 12 is located inside the sleeve 11 and connected to the sleeve 11. The distribution structure 12 can divide the interior of the sleeve 11 into at least a first chamber 13 and a second chamber 14 that are interconnected. The first chamber 13 is located on the side of the distribution structure 12 away from the heat exchange tubes 20, and the second chamber 14 is located on the side of the distribution structure 12 close to the heat exchange tubes 20. The turbulence plate 15 is located inside the second chamber 14 and connected to the sleeve 11. The turbulence plate 15 is spaced apart from the distribution structure 12. A portion of the heat exchange tubes 20 is inserted into the turbulence plate 15 and communicates with the second chamber 14.

[0059] Specifically, the end face of the turbulence plate 15 near the sleeve 11 is completely fitted to the sleeve 11, and the specific arrangement of the turbulence plate 15 and the sleeve 11 is not limited. In this embodiment, the turbulence plate 15 and the sleeve 11 are separately arranged, and the turbulence plate 15 and the sleeve 11 are welded to be completely fitted. In other embodiments, the turbulence plate 15 and the sleeve 11 can also be integrally arranged, simplifying the structure of the distributor 10.

[0060] During operation, the gas-liquid two-phase medium enters the separator 10, first entering the first chamber 13. After being uniformly mixed and distributed by the distribution structure 12, it enters the second chamber 14. A turbulence plate 15 is installed in the second chamber 14. Without the turbulence plate 15, gaps exist between adjacent heat exchange tubes 20 connected to the second chamber 14, causing most of the medium to fill these gaps after entering the second chamber 14, resulting in a decrease in medium utilization and flow rate. The turbulence plate 15 prevents the medium from flowing into these gaps, ensuring that all the medium flows into the heat exchange tubes 20, thus improving medium utilization. Furthermore, it reduces the separation space of the gas-liquid two-phase medium, resulting in more uniform mixing and improved heat exchange efficiency of the heat exchanger 100.

[0061] The turbulence plate 15 has multiple turbulence holes 151 that are adapted to the shape of the heat exchange tubes 20, and each heat exchange tube 20 extends into the corresponding turbulence hole 151. The insertion of the heat exchange tubes 20 into the turbulence holes 151 and their fixed connection with the turbulence plate 15 can further improve the connection strength between the heat exchange tubes 20 and the turbulence plate 15, thereby improving the stability of the heat exchanger 100 structure.

[0062] In one embodiment, the length of the heat exchange tube 20 extending into the turbulence orifice 151 is less than the depth of the turbulence orifice 151. In this way, the medium can enter the heat exchange tube 20 entirely through the turbulence orifice 151, and the medium will not flow into the gap between two adjacent heat exchange tubes 20, thereby reducing the separation space of the gas-liquid two-phase medium, maintaining a high flow rate of the medium, and improving the uniformity and utilization rate of medium mixing.

[0063] In another embodiment, one end of the heat exchange tube 20 extending into the turbulence orifice 151 is flush with the side of the turbulence plate 15 near the distribution structure 12. This prevents the medium from flowing into the gap between adjacent heat exchange tubes 20 and also prevents some medium from filling the turbulence orifice 151. The medium can flow directly into the heat exchange tube 20 entirely, and a high flow rate can be maintained, thereby improving the uniformity and utilization rate of the medium mixing.

[0064] Example 1

[0065] Please see Figures 1-3 The distribution structure 12 is plate-shaped and has multiple distribution holes 1221 connecting the first chamber 13 and the second chamber 14. During operation, the gas-liquid two-phase medium enters the first chamber 13, impacts the plate surface of the distribution structure 12, diffuses outwards, and flows into the adjacent distribution holes 1221. During this process, media flowing in different directions mix with each other, making the mixing scale between media smaller and the gas-liquid mixing more uniform. Furthermore, the throttling effect of the distribution holes 1221 allows the medium to maintain a high flow rate into the second chamber 14. This further improves the uniformity of medium distribution and increases the heat exchange efficiency of the heat exchanger 100.

[0066] In one embodiment, please refer to Figure 1 Multiple distribution holes 1221 are spaced apart along the length of the distribution structure 12. Multiple turbulence holes 151 are spaced apart along the length of the turbulence plate 15. The multiple turbulence holes 151 are arranged in a one-to-one correspondence with the multiple distribution holes 1221. Specifically, the center lines of the turbulence holes 151 and the distribution holes 1221 coincide, which facilitates the flow of the medium. The uniformly distributed medium can quickly enter the heat exchange tube 20, thereby improving the heat exchange performance of the heat exchanger 100.

[0067] Furthermore, the cross-sectional area of ​​the turbulence orifice 151 is larger than that of the distribution orifice 1221. This allows the medium to flow faster through the distribution orifice 1221, thereby further mixing and homogenizing the medium and improving the heat exchange efficiency of the heat exchanger 100.

[0068] In another embodiment, please refer to Figure 2 and Figure 3 Multiple distribution holes 1221 are arranged in a matrix. That is, the distribution holes 1221 are arranged in multiple rows and columns, and the multiple distribution holes 1221 are evenly spaced, which can further play the role of making the gas-liquid two-phase medium mix evenly.

[0069] Furthermore, the dispensing hole 1221 is circular or polygonal in shape. This facilitates processing and allows for the flow of the medium. In other embodiments, the dispensing hole 1221 can be triangular, square, octagonal, or other shapes, as long as the same effect is achieved.

[0070] Preferably, the distribution hole 1221 is circular in shape, and its radius is R1, where 0.5 mm ≤ R1 ≤ 2 mm. By appropriately setting the size of the distribution hole 1221, the uniformity of the medium and the flow resistance can be balanced. If R1 < 0.5 mm, the distribution hole 1221 is too small, the flow resistance of the medium increases, leading to increased energy consumption of the heat exchanger 100. If R1 > 2 mm, the distribution hole 1221 is too large, the flow rate of the medium decreases, resulting in uneven mixing of the medium. For example, the radius R1 of the distribution hole 1221 can be 1 mm, 1.2 mm, or 1.5 mm.

[0071] Example 2

[0072] Please see Figure 4 The distribution structure 12 includes multiple packing elements 121, which are sequentially distributed along the length and width directions of the turbulence plate 15, with adjacent packing elements 121 interconnected to form a plate-like structure. At least one equalization hole 1211 is formed between the multiple packing elements 121, connecting the first chamber 13 and the second chamber 14. During operation, the gas-liquid two-phase medium enters the first chamber 13, impacts the surface of the packing elements 121, diffuses outwards, and flows into the adjacent equalization hole 1211, then into the second chamber 14. During this process, media flowing in different directions mix with each other, resulting in a smaller mixing scale and more uniform gas-liquid mixing. The throttling effect of the equalization hole 1211 further enhances the uniformity of medium mixing and improves the heat exchanger efficiency of the heat exchanger 100. Furthermore, the packing elements 121 increase the impact frequency of the medium, thereby strengthening the gas-liquid mixing effect.

[0073] In one embodiment, please refer to Figure 4 Multiple packing elements 121 are arranged in a matrix. That is, multiple packing elements 121 are arranged in multiple rows and columns. The uniformly spaced packing elements 121 can further play a role in ensuring uniform mixing of the gas and liquid two-phase media.

[0074] In another embodiment, please refer to Figure 5 Along the length of the turbulence plate 15, multiple packing elements 121 are divided into multiple rows. In two adjacent rows of packing elements 121, multiple packing elements 121 in one row are staggered with multiple packing elements 121 in the other row. In this way, the size of the liquid equalization hole 1211 formed by the multiple packing elements 121 is reduced, and the medium can maintain a higher flow velocity when flowing into the liquid equalization hole 1211, thereby improving the uniformity of medium mixing.

[0075] Furthermore, the filler 121 can be a solid of revolution or a polyhedron. A solid of revolution refers to a three-dimensional structure formed by rotating a planar curve around a straight line in the same plane as an axis of rotation; for example, the filler 121 can be a cylinder or a cone. A polyhedron refers to a three-dimensional structure enclosed by four or more polygons; for example, the filler 121 can be a cube, a pyramid, or a prism. In this way, the contact area with the gas-liquid two-phase medium can be increased, further improving the degree of collision between the gas-liquid two-phase medium, thereby improving the mixing uniformity of the medium.

[0076] Preferably, the packing member 121 is spherical. Due to the shape characteristics of the spherical surface, it can increase the impact frequency with the medium, thereby enhancing the gas-liquid mixing effect. The radius of the packing member 121 is R2, where 0.5 mm ≤ R2 ≤ 3 mm. By reasonably setting the size of the packing member 121, the uniformity of the medium and the flow resistance can be balanced. If R2 < 0.5 mm, the size of the liquid equalization hole 1211 formed between adjacent packing members 121 is too small, increasing the resistance when the medium passes through the liquid equalization hole 1211, leading to increased energy consumption of the heat exchanger 100. If R2 > 3 mm, the size of the liquid equalization hole 1211 formed between adjacent packing members 121 is too large, reducing the medium flow rate and causing uneven mixing. For example, the radius R1 of the distribution hole 1221 can be 1 mm, 1.2 mm, or 1.5 mm. In other embodiments, the appropriate size of the filler 121 can be selected according to the flow rate of the medium in the actual application. As the flow rate increases, the size of the filler 121 also increases.

[0077] Example 3

[0078] Please see Figure 6 The distribution structure 12 includes a distribution plate 122 and multiple fillers 121.

[0079] The distribution plate 122 has multiple distribution holes 1221 connecting the first chamber 13 and the second chamber 14. The distribution holes 1221 have a throttling effect; the medium experiences some resistance as it passes through them. Due to different gas-liquid mixing ratios, the resistance generated by the medium flowing through the distribution holes 1221 varies. This difference in resistance ensures thorough mixing of the gas and liquid, thus initially achieving uniform liquid distribution. Furthermore, it can increase the flow rate of the medium.

[0080] Multiple packing elements 121 serve to ensure uniform mixing of the medium and occupy the internal space of the distributor 10. When the gas-liquid two-phase medium flows into the distributor 10, due to the certain gaps between the multiple packing elements 121, the gas-liquid two-phase medium can maintain a high flow rate. Moreover, due to the interference of the packing elements 121, the gas-liquid two-phase medium continuously collides and interferes with each other, thereby making the mixing scale between the medium smaller, that is, improving the uniformity of the gas-liquid two-phase medium mixing, thereby improving the heat exchange efficiency of the heat exchanger 100.

[0081] In one embodiment, a plurality of fillers 121 are located in the first chamber 13 and connected to the distribution plate 122.

[0082] After the medium enters the first chamber 13, it first passes through the packing member 121 to make the gas and liquid mix evenly, and then passes through the distribution hole 1221 to be evenly distributed into the second chamber 14, and then flows into the heat exchange tube 20 for heat exchange, thus further improving the uniformity of the medium mixing.

[0083] In another embodiment, a plurality of fillers 121 are located in the second chamber 14 and connected to the distribution plate 122. After the medium enters the first chamber 13, it is first evenly distributed into the second chamber 14 through the distribution hole 1221, and then further mixed evenly by the fillers 121 before flowing into the heat exchange tube 20 for heat exchange, thus further improving the uniformity of medium mixing.

[0084] In another embodiment, multiple packing elements 121 are located in the first chamber 13 and the second chamber 14, respectively, and are connected to the distribution plate 122. After the medium enters the first chamber 13, it is first mixed uniformly by the packing elements 121, and then uniformly distributed into the second chamber 14 through the distribution holes 1221. After being further mixed uniformly by the packing elements 121 in the second chamber 14, it flows into the heat exchange tube 20 for heat exchange, thus further improving the uniformity of medium mixing.

[0085] Please see Figure 4 and Figure 5 Multiple packing elements 121 are sequentially distributed along the length and width directions of the distribution plate 122, and adjacent packing elements 121 are interconnected to form a plate-like structure. Each packing element 121 forms at least one equalizing hole 1211. The mutual abutment and connection between adjacent packing elements 121 reduces the gap between them, increases the flow rate of the medium, and thus improves the uniformity of the gas-liquid two-phase mixing. Furthermore, it also enhances the connection strength between the packing elements 121, increasing the structural stability of the distributor 10.

[0086] In one embodiment, a plate-like structure formed by multiple packing elements 121 is located in the first chamber 13 and connected to the distribution plate 122. After the medium enters the first chamber 13, it impacts the surface of the packing elements 121 and flows into adjacent equalization holes 1211 for initial uniform distribution. It then flows through the equalization holes 1211 to the distribution holes 1221 for a second uniform distribution before entering the second chamber 14 and flowing into the heat exchange tube 20 for heat exchange. The combined action of the packing elements 121 and the distribution holes 1221 makes the gas-liquid mixture more uniform and achieves uniform distribution. This further improves the heat exchange efficiency of the heat exchanger 100.

[0087] In another embodiment, a plate-like structure formed by multiple packing elements 121 is located in the second chamber 14 and connected to the distribution plate 122. After the medium enters the first chamber 13, it undergoes a first uniform distribution through the distribution holes 1221, then enters the second chamber 14, impacts the surface of the packing elements 121, and flows out through adjacent liquid equalization holes 1211 for a second uniform distribution before flowing into the heat exchange tube 20 for heat exchange. The combined action of the packing elements 121 and the distribution holes 1221 makes the gas-liquid mixture more uniform and achieves uniform distribution. This further improves the heat exchange efficiency of the heat exchanger 100.

[0088] In another embodiment, both the first chamber 13 and the second chamber 14 are provided with plate-like structures formed by multiple packing elements 121, which are respectively connected to the distribution plate 122. After the medium enters the first chamber 13, it impacts the surface of the packing elements 121 and flows into the adjacent liquid equalization holes 1211 for the first uniform distribution. It then flows to the distribution hole 1221 for the second uniform distribution before entering the second chamber 14. In the second chamber 14, the medium impacts the surface of the packing elements 121 and flows out from the adjacent liquid equalization holes 1211 for the third uniform distribution before flowing into the heat exchange tube 20 for heat exchange. Under the combined action of the packing elements 121 and the distribution holes 1221, the gas-liquid mixture is made more uniform, and uniform distribution is achieved. In this way, the heat exchange efficiency of the heat exchanger 100 is further improved.

[0089] In one embodiment, please refer to Figure 4 Multiple filler elements 121 are arranged in a matrix. The uniformly spaced filler elements 121 can further play a role in uniformly mixing the medium.

[0090] In another embodiment, please refer to Figure 5 Along the length of the distribution plate 122, multiple fillers 121 are divided into multiple rows. In adjacent rows of fillers 121, multiple fillers 121 in one row are staggered with multiple fillers 121 in the other row. This further reduces the size of the equalization orifice 1211 formed by the multiple fillers 121, allowing the medium to maintain a higher flow rate when flowing into the equalization orifice 1211, thereby improving the uniformity of medium mixing. Of course, in other embodiments, the multiple fillers 121 can also be arranged in a ring shape on the distribution plate 122, as long as the same effect is achieved.

[0091] Please see Figure 6The turbulence plate 15 has multiple turbulence holes 151 that are adapted to the shape of the heat exchange tube 20. The multiple turbulence holes 151 are spaced apart along the length of the turbulence plate 15, and multiple distribution holes 1221 are spaced apart along the length of the distribution plate 122, with the center lines of the turbulence holes 151 and the distribution holes 1221 coinciding. It can be understood that after the medium enters the first chamber 13, it can quickly flow into the second chamber 14 through the distribution holes 1221 on the distribution plate 122. Since the center lines of the distribution holes 1221 and the turbulence holes 151 coincide, that is, the distribution holes 1221 are directly opposite the turbulence holes 151, it is convenient for the medium to flow. The evenly distributed medium can directly enter the heat exchange tube 20, thereby improving the heat exchange performance of the heat exchanger 100.

[0092] Furthermore, the turbulence plate 15 has multiple turbulence holes 151 that are adapted to the shape of the heat exchange tube 20, and the cross-sectional area of ​​the turbulence holes 151 is larger than the cross-sectional area of ​​the distribution holes 1221. This allows the medium to flow faster when passing through the distribution holes 1221, thereby further mixing the medium evenly and improving the heat exchange efficiency of the heat exchanger 100.

[0093] Please see Figure 1 , Figure 6 and Figure 7 The sleeve 11 provided in this application includes a main body 111, a first end cap 112, and a second end cap 113. The first end cap 112 is sealed at one end of the main body 111; the second end cap 113 is sealed at the end of the main body 111 away from the first end cap 112. In this way, the sleeve 11 can be sealed, allowing the medium to flow along the planned flow path and avoiding leakage. Furthermore, the first end cap 112 and the second end cap 113 facilitate the assembly and positioning of the distribution plate 122 and the turbulence plate 15, thereby improving the assembly efficiency of the heat exchanger 100.

[0094] An inlet pipe 40 is installed on the tube wall of the sleeve 11 opposite to the heat exchange tube 20.

[0095] Please see Figure 6 In one embodiment, the sleeve 11 is a cuboid. The square-shaped sleeve 11 facilitates welding with the heat exchange tube 20 and the inlet pipe 40, thereby improving the production efficiency of the heat exchanger 100.

[0096] Please see Figure 7 In another embodiment, the sleeve 11 is a cylinder. The cylindrical sleeve 11 can be connected to the inlet pipe 40 by means of a pipe seat 50. The side of the pipe seat 50 near the sleeve 11 is a curved surface that matches the side of the sleeve 11, which is convenient for welding and fixing with the sleeve 11. The side of the pipe seat 50 away from the sleeve 11 is a flat surface, which is convenient for connecting with the heat exchange tube 20 and the inlet pipe 40.

[0097] This application also provides a heat exchanger 100, which includes a distributor 10, multiple fins 30, and multiple heat exchange tubes 20. The distributor 10 is the same as described above. The multiple fins 30 are arranged alternately and side by side. The heat exchange tubes 20 are inserted through the fins 30, and one end of the heat exchange tubes 20 is connected to the distributor 10. The heat exchanger 100 also includes a manifold (not shown), which is used to collect the heat-exchanged medium.

[0098] In one embodiment, multiple heat exchange tubes 20 are arranged in a row at intervals along the height direction of the heat exchanger 100. In other embodiments, multiple heat exchange tubes 20 are arranged in multiple rows at intervals along the width direction of the heat exchanger 100, and adjacent rows of heat exchange tubes 20 are connected by bends. When the number of rows of heat exchange tubes 20 is odd, the manifold is located on the side of the heat exchanger 100 away from the distributor 10; when the number of rows of heat exchange tubes 20 is even, the manifold is located on the same side of the heat exchanger 100 as the distributor 10.

[0099] Furthermore, the heat exchanger 100 also includes a distributor (not shown), one end of which is connected to the liquid distributor 10. The distributor includes a capillary tube connected to the inlet pipe 40.

[0100] In actual use, the distributor 10 is set vertically. When the heat exchanger 100 is working, the medium enters the connected inlet pipe 40 from the capillary tube on the distributor, and then enters the distributor 10. After being evenly distributed by the distribution structure 12 and the turbulence plate 15, it enters the heat exchange tube 20, and then exchanges heat with the outside through the fins 30. The medium after heat exchange is collected in the manifold and flows out.

[0101] For further details, please refer to Figure 9 There are multiple liquid separators 10, which are distributed at intervals along the height direction of the heat exchanger 100; there are also multiple capillary tubes, which are connected to the corresponding inlet pipes 40.

[0102] In other embodiments, the number of distributors 10 and capillaries on the heat exchanger 100 can be changed according to actual needs. For example, there can be one, two, or three distributors 10 and capillaries, as long as the number of distributors 10 and capillaries is consistent.

[0103] For further details, please refer to Figure 8 and Figure 9 In this application, a single distributor 10, together with the inlet pipe 40 and multiple heat exchange tubes 20, forms a distributor unit 60. This facilitates modular production and improves the production efficiency of the heat exchanger 100.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
