Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a heat exchanger for heating, ventilation and air conditioning. Background Technology

[0002] In related technologies, heat exchangers mainly consist of multiple heat exchange tubes and multiple parallel fins. Refrigerant flows inside the heat exchange tubes, which are connected to the fins. The fins exchange heat with the air. In some designs, to increase heat exchange performance and meet different application and installation requirements, heat exchangers are also made into large-size heat exchangers. Because the heat exchange tubes used in large-size heat exchangers are longer, they are assembled by splicing the heat exchange tubes together. When testing the performance of such large products, it was found that the heat exchangers have a problem of low structural strength. Summary of the Invention

[0003] Therefore, the purpose of this application is to propose a heat exchanger that is beneficial to improving the structural strength of the heat exchange tubes.

[0004] This application discloses a heat exchanger comprising a first heat exchange section and a second heat exchange section. The first heat exchange section includes a first tube and a plurality of first heat exchange tubes arranged along the length of the first tube. The second heat exchange section includes a second tube and a plurality of second heat exchange tubes arranged along the length of the second tube. One end of each first heat exchange tube is connected to one end of each second heat exchange tube, and the other end of each first heat exchange tube is connected to the first tube. The heat exchanger also includes a limiting assembly comprising a first member and a second member connected together. The first member includes a first body portion, which includes a mounting portion. A portion of the first heat exchange tube is located in the mounting portion, and the second member is connected to the second heat exchange section; or, a portion of the second heat exchange tube is located in the mounting portion, and the second member is connected to the first heat exchange section.

[0005] The heat exchanger proposed in this application includes a first heat exchange section, a second heat exchange section, and a limiting assembly. The first heat exchange section includes a first heat exchange tube and a first pipe, and the second heat exchange section includes a second heat exchange tube and a second pipe. The first heat exchange tube is connected to the second heat exchange tube. The limiting assembly includes a first piece and a second piece, which are connected. The first piece is connected to the first heat exchange tube, and the second piece is connected to the second heat exchange section; alternatively, the first piece is connected to the second heat exchange tube, and the second piece is connected to the first heat exchange section. Therefore, the limiting assembly can reduce bending deformation of the connection section between the first and second heat exchange tubes, reduce the risk of the first and second heat exchange tubes detaching, and improve the structural strength of the heat exchanger.

[0035] First fin 16, second fin 17 Detailed Implementation

[0036] To better understand the technical solution of this application, the embodiments of this application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or fixture referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.

[0037] The specific structure of the heat exchanger according to an embodiment of this application is described below with reference to the accompanying drawings.

[0038] The heat exchanger 1 in this embodiment includes a first heat exchange section 100 and a second heat exchange section 200, which are assembled and welded together. Specifically, as shown... Figure 1 The heat exchanger 1 shown has a first heat exchange section 100 including a first heat exchange tube 13 and a first tube 11, and a second heat exchange section 200 including a second heat exchange tube 15 and a second tube 12. Typically, the first tube 11 and the second tube 12 can have the same structure. In other words, the shape and structure of the first tube 11 and the second tube 12 can be designed according to the performance requirements of the heat exchanger 1. For example, the cross-sectional shape of the first tube 11 and the second tube 12 can be different, and the height or diameter of the first tube 11 and the second tube 12 can be set to be the same or different. The first tube 11 has a first inner cavity, and the second tube 12 has an inner cavity.

[0039] In some applications, the length of the first heat exchange tube 13 and the second heat exchange tube 15 after connection may be as long as two or three meters. Since the first heat exchange tube 13 and the second heat exchange tube 15 are made of aluminum alloy, and aluminum alloy has low hardness, the connection section of the first heat exchange tube 13 and the second heat exchange tube 15 is at risk of bending and deformation. Especially in some products with poor welding quality, there are some places with incomplete welding. In such cases, bending and deformation of the connection section can easily lead to the risk of the first heat exchange tube 13 and the second heat exchange tube 15 falling off.

[0040] The first heat exchange tube 13 has a channel (not shown in the figure), and the second heat exchange tube 15 has a channel (not shown in the figure). One end of the first heat exchange tube 13 is connected to the first tube 11, and the other end of the first heat exchange tube 13 is connected to one end of the second heat exchange tube 15. The other end of the second heat exchange tube 15 is connected to the second tube 12. The first tube 11 is connected to the first heat exchange tube 13, the first heat exchange tube 13 is connected to the second heat exchange tube 15, and the second heat exchange tube is connected to the second tube. In some designs, the other end of the second heat exchange tube 15 includes a flared portion 151 to facilitate insertion and connection with the first heat exchange tube 13. Furthermore, the first heat exchange tube 13 may also include a flared portion 151 to allow for free combination of tubes with different diameters, thereby enabling the heat exchanger 1 to adjust the heat exchange capacity of different areas of the heat exchanger 1 under cooling or heating conditions.

[0041] Specifically, such as Figure 1 The heat exchanger 1 shown includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16. The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. A second heat exchange tube 15 and a plurality of second fins 17, wherein the second fins 17 are plate-type structures, and the plurality of first fins 17 are spaced apart along the length of the second heat exchange tube 15. A second heat exchange tube 15 passes through the plurality of second fins 17 arranged along the length of the second heat exchange tube 15, and the plurality of second heat exchange tubes 15 are spaced apart along the length of the second fins 17. One end of the first heat exchange tube 11 is connected to one end of the second heat exchange tube 15, and the other end of the first heat exchange tube (13) is connected to the first tube 1. The other end of the second heat exchange tube 15 is connected to the second tube 17. The second heat exchange tube 15 also includes a flared portion 151. Specifically, one end of the second heat exchange tube with the flared portion 151 is connected to one end of the first heat exchange tube 13, and the other end of the second heat exchange tube 15 is connected to the second tube 12. The other end of the first heat exchange tube 13 is connected to the first tube 11.

[0042] Specifically, in some embodiments, such as Figure 1 and Figure 2As shown, the limiting component 14 includes a first part 141, a second part 142, and a third part 143. The third part 143 is a connector. The first part 141 includes a first body portion 1411, which includes a plurality of first mounting portions 1412. Each first mounting portion 1412 has an opening. The plurality of first mounting portions 1412 are spaced apart along the length of the first part 141. Along the length of the first part 141, the opening directions of two adjacent first mounting portions 1412 are opposite. The second part 142 includes a second body portion 1421, which includes a plurality of second mounting portions 1422. The plurality of second mounting portions 1422 are spaced apart vertically along the length of the second part 142. Along the length of the second part 142, the opening directions of two adjacent second mounting portions 1422 are opposite. Along the width of the limiting component 14, the opening directions of adjacent first mounting portions 1412 and second mounting portions 1422 are opposite. One end of the third component 143 is connected to the first component 141, and the other end of the third component 143 is connected to the second component 142. It can be understood that the number of third components 143 can be one, two, or more; there is no limit to the number. If there are two or more third components 143, such as... Figure 2 As shown, multiple third parts 143 can be spaced apart along the length of the first part 143, with a gap between adjacent third parts 143. The multiple third parts 143 can be used to improve the connection strength between the first part 141 and the second part 142. It is understood that the limiting component 14 can be obtained by welding or gluing the first part 141, the second part 142 and the third part 143 together, or the first part 141 and the third part 143 can be fixed to the second part 142 as an integral structure by welding or gluing, or the second part 142 and the third part 143 can be fixed to the first part 141 as an integral structure by welding or gluing. No specific limitation is made here.

[0043] In some embodiments, such as Figure 1 The heat exchanger shown has a first component 141 that is snapped and fixedly connected to a second heat exchange tube 15, a second component 142 that is connected to a first heat exchange tube 13, and a third component 143 that connects the first component 141 and the second component 142. A flared portion 151 is located between the first component 141 and the second component 142. Therefore, the first component 141 can reduce the bending deformation of the connection section between the second heat exchange tube 15 and the first heat exchange tube 15, thereby reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 detaching.

[0044] like Figure 1As shown, the first heat exchange tube 13 is inserted into the second mounting portion 1422 of the second component 142, and the second heat exchange tube 15 is inserted into the first mounting portion 1412 of the first component 141. Therefore, when the first tube 11 and the second tube 12 of the heat exchanger 1 are placed horizontally, the first mounting portion 1412 and the second mounting portion 1422 adjacent in the width direction of the first component 141 will have their openings facing downwards and their openings facing upwards. This structure makes the forces of the first heat exchange tube 13 and the second heat exchange tube 15 in the vertical direction more balanced. In particular, for tubes with an overall length of more than two or three meters, the bending deformation in the middle area of ​​the heat exchanger 1 is reduced regardless of whether the heat exchanger is placed in the forward or reverse direction, which helps to improve the connection strength of the heat exchanger 1.

[0045] In some embodiments, such as Figure 3 As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16. The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12, a plurality of first fins 13, and a plurality of first fins 16. Two heat exchange tubes 15 and multiple second fins 17, the second fins 17 having a plate-like structure, multiple first fins 17 being spaced apart along the length of the second heat exchange tube 15, one second heat exchange tube 15 passing through multiple second fins 17 arranged along the length of the second heat exchange tube 15, multiple second heat exchange tubes 15 being spaced apart along the length of the second fins 17, one end of the first heat exchange tube 11 being connected to one end of the second heat exchange tube 15, the other end of the first heat exchange tube 13 being connected to the first tube 11, and the other end of the second heat exchange tube 15 being connected to the second tube 17.

[0046] In some embodiments, such as Figure 3 and Figure 4As shown, the heat exchanger also includes a limiting assembly 14, which includes a first member 141, a second member 142, and a third member 143. The first member 141 includes a first body portion 1411, which has a plurality of first mounting portions 1412. The plurality of first mounting portions 1412 are spaced apart along the length of the first member 141, and each first mounting portion 1412 has an opening facing the same direction. The second member 142 includes a second body portion 1421, which has a plurality of second mounting portions 1422. The second mounting portion 1422 is spaced apart along the length of the second part 142. The second mounting portion 1422 has an opening, and the openings of the multiple second mounting portions 1422 face the same direction. In the width direction of the limiting assembly 14, the openings of adjacent first mounting portions 1412 and second mounting portions 1422 face the same direction. One end of the third part 143 is connected to one end of the second part 142, and the other end of the third part 143 is connected to the first part 141. The openings of the first mounting portions 1412 and the second mounting portions 1422 face the same direction, which facilitates the combined installation of the limiting assembly 14 with the first heat exchange tube 13 and the second heat exchange tube 15.

[0047] In some embodiments, such as Figure 2 As shown, the first component 141 is snapped and fixedly connected to the second heat exchange tube 15, and the second component 142 is snapped and fixedly connected to the first heat exchange tube 13. The first component 141 and the second component 142 are fixedly connected by a third component 143. The second heat exchange tube 15 includes a flared portion 151, which is located between the first component 141 and the second component 142. Therefore, the first component 141 can reduce the bending deformation of the connection section between the second heat exchange tube 15 and the first heat exchange tube 15 with the flared portion 151, thereby reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 separating and improving the connection strength of the heat exchanger 1.

[0048] In some embodiments, such as Figure 3 and Figure 5 As shown, the first heat exchange tube 13 includes a protrusion 131, which protrudes from the tube wall of the first heat exchange tube 13 in the circumferential direction. The tube wall of the first heat exchange tube 13 refers to the tube section excluding the protrusion 151.

[0049] Furthermore, by placing the protrusion 131 between the first piece 141 and the second piece 142, the protrusion 131 can restrict the movement of the second piece 142 toward the second tube 12, which is beneficial to further improve the connection strength and reliability of the limiting assembly 1, thereby reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 detaching.

[0050] It is understood that in some embodiments, such as Figures 3 to 5The heat exchanger 1 shown has a first heat exchange tube 13 including a protrusion. In some designs, the protrusion can be a flange, which is a complete outer wall of the first heat exchange tube 13. The protrusion can also be a half-circle or two-thirds of the outer wall of the first heat exchange tube 13, that is, not a full circle. Usually, the protrusion is located near the flared part 151 of the first heat exchange tube 13, with a preset distance between them.

[0051] In some embodiments, such as Figure 6 and Figure 8 As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16. The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12, a plurality of first fins 13, and a plurality of first fins 16. Two heat exchange tubes 15 and multiple second fins 17, the second fins 17 having a plate-like structure, multiple first fins 17 being spaced apart along the length of the second heat exchange tube 15, one second heat exchange tube 15 passing through multiple second fins 17 arranged along the length of the second heat exchange tube 15, multiple second heat exchange tubes 15 being spaced apart along the length of the second fins 17, one end of the first heat exchange tube 11 being connected to one end of the second heat exchange tube 15, the other end of the first heat exchange tube 13 being connected to the first tube 11, and the other end of the second heat exchange tube 15 being connected to the second tube 17.

[0052] Furthermore, the heat exchanger 1 also includes a limiting assembly 14, which includes a first member 141, a second member 142, and a third member 143. The first member 141 includes a first body portion 1411, which has a plurality of first mounting portions 1412. The plurality of first mounting portions 1412 are spaced apart along the length of the first member 141, and each first mounting portion 1412 has an opening facing the same direction. The second member 142 includes a second body portion 1421, which has a plurality of second mounting portions 1422. 2. The second mounting portion 1422 is spaced apart along the length of the second part 142. The second mounting portion 1422 has an opening. The openings of the multiple second mounting portions 1422 face the same direction. In the width direction of the limiting assembly 14, the openings of adjacent first mounting portions 1412 and second mounting portions 1422 face the same direction. One end of the third part 143 is connected to one end of the second part 142, and the other end of the third part 143 is connected to the first part 141. The openings of the first mounting portions 1412 and the second mounting portions 1422 face the same direction, which facilitates the combined installation of the limiting assembly 14 with the first heat exchange tube 13 and the second heat exchange tube 15.

[0053] Furthermore, the first heat exchange tube 13 includes a recess 132, which is recessed inward. The recess 132 can completely surround the entire outer wall of the first heat exchange tube 13, or it can be partially or two-thirds of the way around the outer wall of the first heat exchange tube 13, meaning it does not completely encircle the tube. Typically, the recess 132 is located near the flared portion 151 of the first heat exchange tube 13, with a predetermined distance between them. The second heat exchange tube 15 includes a flared portion 151. The first piece 141 is connected to the second heat exchange tube 15, and the second piece 142 is snap-fitted to the first heat exchange tube 13. The second mounting portion 1422 is fitted with the recess 132 for installation. The recess 132 can improve the secure and reliable connection between the second piece 142 and the first heat exchange tube 13, and also reduce the risk of the second heat exchange tube 15 and the first heat exchange tube 13 detaching.

[0054] In some embodiments, such as Figure 7 As shown, the length of the opening of the second mounting part 1422 is L2, the width of the opening of the first mounting part 1412 is L1, and L2 is less than L1.

[0055] In some embodiments, such as Figure 9 and Figure 10As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16. The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12, a plurality of first fins 13, and a plurality of first fins 16. Two heat exchange tubes 15 and multiple second fins 17, the second fins 17 having a plate-like structure, multiple first fins 17 being spaced apart along the length of the second heat exchange tube 15, one second heat exchange tube 15 passing through multiple second fins 17 arranged along the length of the second heat exchange tube 15, multiple second heat exchange tubes 15 being spaced apart along the length of the second fins 17, one end of the first heat exchange tube 11 being connected to one end of the second heat exchange tube 15, the other end of the first heat exchange tube 13 being connected to the first tube 11, and the other end of the second heat exchange tube 15 being connected to the second tube 17.

[0056] In some implementations, such as Figure 9 and Figure 10As shown, the heat exchanger 1 also includes two limiting components 14. Each limiting component 14 includes a first part 141 and a second part 142. The first part 141 includes a first body portion 1411, which includes a plurality of first mounting portions 1412. The plurality of first mounting portions 1412 are spaced apart along the length of the first part 141. One of the two limiting components 14 includes a limiting component 14 and the other limiting component 14. One end of the first part 141 of the limiting component 14 is connected to the second part 142 of the limiting component 14. The connection is as follows: one end of the first piece 141 of one limiting component 14 is connected to the second piece 142 of the other limiting component 14; the first piece 141 of the other limiting component 14 is connected to the second piece 142 of one limiting component 14; the opening directions of the two first pieces 141 are set to face each other; one end of the second piece 142 of one limiting component 14 is connected to one end of the first tube 11; the other end of the second piece 142 of one limiting component 14 is connected to one end of the second tube; the second piece 142 of the other limiting component 14... The other end of 42 is connected to the other end of the first tube 11. The other end of the second piece 142 of a limiting assembly 14 is connected to the other end of the first tube 11. The other end of the second piece of a limiting assembly 14 is connected to the other end of the second tube 12. The two limiting assemblies 14 include one limiting assembly 14 and the other limiting assembly 14. One end of the first fin 16 is connected to the second piece 142 of one limiting assembly 14. The other end of the first fin 16 is connected to the second piece 142 of the other limiting assembly 14. One end of the second fin 17 is connected to the second piece of one limiting assembly 14. The other end of the second fin 7 is connected to the second piece 142 of the other limiting assembly 14. Therefore, the supporting force of the first fin 16 on the first heat exchange tube 13 and the supporting force of the second fin 17 on the second heat exchange tube 15 are increased. Thus, the first fin 16 can provide supporting force on both sides of the heat exchanger in the fin width direction, so that the heat exchanger 1 is subjected to uniform force, thereby reducing the bending deformation in the middle area of ​​the heat exchanger 1 and improving the reliability of the heat exchanger 1.

[0057] In some embodiments, such as Figure 9 and Figure 10As shown, the second component 142 also includes a first reinforcing part 1423 and a second reinforcing part 1424. One end of the first reinforcing part 1423 is connected to one end of the second component 142, and the other end of the second reinforcing part 1424 is connected to the other end of the second component 142. The first reinforcing part 1423 is connected to the first tube 11, and the second reinforcing part 1424 is connected to the second tube 12. In some embodiments, the first reinforcing part 1423 and the second reinforcing part 1424 can be annular structures. The first reinforcing part 1423 is sleeved on the outside of the first tube 11, and the second reinforcing part 1424 is sleeved on the outside of the second tube 12. It can also be an arc-shaped structure. The first reinforcing part 1423 is welded to the outer wall of the first tube 11, and the second reinforcing part 1424 is welded to the outer wall of the second tube 12.

[0058] In some embodiments, such as Figures 11 to 12 As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16. The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12, a plurality of first fins 13, and a plurality of first fins 16. Two heat exchange tubes 15 and multiple second fins 17, the second fins 17 having a plate-like structure. Multiple first fins 17 are spaced apart along the length of the second heat exchange tube 15. One second heat exchange tube 15 passes through the multiple second fins 17 arranged along the length of the second heat exchange tube 15. One end of a first heat exchange tube 11 is connected to one end of a second heat exchange tube 15, the other end of a first heat exchange tube 13 is connected to a first tube 1, and the other end of a second heat exchange tube 15 is connected to a second tube 17. The second heat exchange tube 15 also includes a flared portion 151. Specifically, one end of the second heat exchange tube with the flared portion 151 is connected to one end of the first heat exchange tube 13, the other end of the second heat exchange tube 15 is connected to a second tube 12, and the other end of the first heat exchange tube 13 is connected to the first tube 11.

[0059] Specifically, such as Figure 12As shown, the limiting component 14 includes a first piece 141 and a second piece 142. The first piece 141 includes a first main body portion 1411, which includes a first mounting portion 1412. The first mounting portion 1412 has a through hole that penetrates the first main body portion 1411. The first piece 141 and the second piece 142 are connected, with the first piece 141 connected to one side of the second piece 142 in the thickness direction.

The first connecting portion 1425 and the second connecting portion 1426 can be adjusted accordingly based on the tubular shape of the first tube and the second tube.

[0060] Furthermore, such as Figure 11 As shown, the heat exchanger includes two limiting members 14.

One end of the second member 142 is connected to the first tube 11, and the other end is connected to the second tube. The position of the first member 141 is related to the connection point of the first heat exchange tube 13 and the second heat exchange tube 15. Generally, the first member 141 is positioned close to the connection section of the first heat exchange tube 13 and the second heat exchange tube 15, thereby enhancing the reliability of the connection between the two ends of the heat exchanger 1 in the length direction of the first tube 11. The two limiting components 14 include one limiting component 14 and the other limiting component 14. One end of the first fin 16 is connected to the second piece 142 of one limiting component 14, and the other end of the first fin 16 is connected to the second piece 142 of the other limiting component 14. One end of the second fin 17 is connected to the second piece 142 of one limiting component 14, and the other end of the second fin 17 is connected to the second piece 142 of the other limiting component 14. Therefore, the supporting force of the first fin 16 on the first heat exchange tube 13 and the supporting force of the second fin 17 on the second heat exchange tube 15 are increased, thereby reducing the deformation of the middle region of the heat exchanger 1 and reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 detaching.

[0061] In some embodiments, such as Figures 12 to 15As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16. The first fins 16 have a plate-like structure. The plurality of first fins 16 are spaced apart along the length of the first heat exchange tubes 13. A first heat exchange tube 13 passes through the plurality of first fins 16 arranged along the length of the first heat exchange tube 13. The plurality of first heat exchange tubes 13 are spaced apart along the length of the first fins 16.

In some embodiments, multiple first pieces 141 are provided. Specifically, for example... Figure 16As shown, multiple first pieces 141 are spaced apart along the length of the second piece 142. Along the width of the second piece 142, the multiple second pieces 142 can be divided into two columns of second components 142. The number of second components 142 in the two columns can be unequal. The opening directions of the second components 142 in the same column are the same, while the opening directions of the second components 142 in different columns are opposite. In some embodiments, two limiting components 14 can be provided. The two limiting components 14 are located on opposite sides along the width of the second piece and are not aligned. The opening directions of the two limiting components 14 are opposite. The two limiting components 14 include one limiting component 14 and the other limiting component 14. Furthermore, one end of the first fin 16 is connected to the second piece 142 of one of the limiting components 14, and the other end of the first fin 16 is connected to the second piece 142 of another limiting component 14. One end of the second fin 17 is connected to the second piece 142 of one of the limiting components 14, and the other end of the second fin 17 is connected to the second piece 142 of another limiting component 14. Therefore, the supporting force of the first fin 16 on the first heat exchange tube 13 and the supporting force of the second fin 17 on the second heat exchange tube 15 are increased, thereby reducing the deformation of the middle region of the heat exchanger 1 and reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 detaching.

[0063] In some embodiments, such as Figures 16 to 18 As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16.

The heat exchanger 1 also includes a second heat exchange section 200, which includes a second tube 12. The system includes multiple second heat exchange tubes 15 and multiple second fins 17, with the second fins 17 having a plate-like structure.

[0064] Furthermore, the second heat exchange tube 15 includes a flared portion 151, a bent portion 152, and a straight section 153.

The first fin 16 is connected to the second component 142. The connection between the first fin 16 and the second component 142 is beneficial to improving the support force of the first fin 16 on the first heat exchange tube 1, improving the overall support force of the first heat exchange part 100, and thus improving the overall connection reliability of the heat exchanger 1.

[0067] In some embodiments, such as Figure 16 As shown, the heat exchanger 1 includes two limiting components 14, which are located on both sides of the first tube 11 in the height direction and are both connected to the first heat exchange section 100. Therefore, one end of the first fin 16 is connected to the second piece 142 of one of the limiting components 14, and the other end of the first fin 16 is connected to the second piece 142 of the other limiting component 14. This helps to improve the overall support of the first heat exchange section 100, thereby improving the overall connection reliability of the heat exchanger 1 and reducing the risk of the first heat exchange tube 13 and the second heat exchange tube 15 becoming detached.

[0068] In some implementations, such as Figures 19 to 23As shown, the heat exchanger 1 includes a first heat exchange section 100, which includes a first tube 11, a plurality of first heat exchange tubes 13, and a plurality of first fins 16.

[0069] In some embodiments, such as Figure 23 As shown, the second heat exchange tube 15 also includes a flared portion 151, a bent portion 152, and a straight section 153. One end of the bent portion 153 is connected to the flared portion 151, the other end of the bent portion 153 is connected to the straight section 153, the other end of the straight section 153 is connected to the second tube 12, the flared portion 151 is connected to one end of the first heat exchange tube 13, and the other end of the first heat exchange tube 13 is connected to the first tube 11.
