Fin and heat exchanger

Abstract

The present disclosure relates to the technical field of heat exchange, and provides a fin and a heat exchanger. The fin comprises a fin body, first supporting members, and second supporting members, and the fin body is provided with a plurality of mounting recesses spaced apart along the length direction of the fin body. The first supporting members are arranged at one end in the width direction of the fin body, the second supporting members are arranged at the other end in the width direction of the fin body, and the first supporting members at least partially overlap with the second supporting members in the width direction of the fin body. The first supporting members and the second supporting members can support adjacent fins from two sides in the width direction of the fin body, thereby improving the stability and reliability of the support and effectively solving positioning and support issues between fins. The first supporting members are disposed on the side of the fin body close to the mounting recesses, and the second supporting members are disposed on the side of the fin body away from the mounting recesses. Thus, when fins are arranged and installed in a stacked configuration, even if subjected to external forces, the installed fins will not tilt, thereby reducing the risk of support loss and fin damage.

On the contrary, these implementations are provided to make the present disclosure comprehensive and complete, and fully convey concepts of the exemplary embodiments to those skilled in the art.

[0014] FIG. 1 shows a first schematic diagram of one form of a fin according to an embodiment of the present disclosure; FIG. 2 shows a second schematic diagram of one form of the fin according to an embodiment of the present disclosure.

[0015] As shown in FIGS. 1-2, this embodiment provides a fin including a fin body 1. The fin body 1 is provided with a plurality of mounting recesses 11 spaced along a length direction of the fin body 1. One end of the fin body 1 in a width direction is provided with a first supporting member 2, and the other end of the fin body 1 in the width direction is provided with a second supporting member 3. The first supporting member 2 and the second supporting member 3 at least partially overlap along the width direction of the fin body 1.

[0016] The fin provided in this embodiment includes the first supporting member 2 and the second supporting member 3 arranged on both sides of the fin body 1 in the width direction, respectively, and the first supporting members 2 and second supporting members 3 can support adjacent fins from both sides of the fin body 1 in the width direction, improving support stability and reliability and effectively solving a problem related to positioning and support between fins. The first supporting member 2 is disposed at one end of the fin body 1 in the width direction, and the second supporting member 3 is disposed at the other end of the fin body 1 in the width direction. When the fins are stacked and mounted, even if they are subjected to external force, the fins will not tilt during the mounting, reducing risks of support loss and damage to the fins.

[0017] It can be understood that the length direction of the fin body 1 is defined as a first direction, which is denoted by D1; the width direction of the fin body 1 is defined as a second direction, which is denoted by D2; a thickness direction of the fin body 1 is defined as a third direction, which is denoted by D3, in which the first direction, the second direction, and the third direction are perpendicular to one another, and they only represent spatial directions and have no substantive meaning.

[0018] In one embodiment, as shown in FIGS. 1-2, the first supporting member 2 and / or the second supporting member 3 are formed by folding a cut material on the fin body 1.

[0019] By directly utilizing surplus material on the fin body 1 to form the first supporting member 2 and the second supporting member 3 of flanged structures, material utilization is improved, eliminating need for additional tooling assistance and effectively saving material costs, and fins with built-in positioning support structures can be formed, facilitating assembly. The first supporting member 2 and the second supporting member 3 may be formed by stamping, which saves material costs, does not require additional tooling, is easy to assemble, and enables large-scale and industrialized production.

[0020] In addition, fin positioning requirements for different spacing can be achieved by selecting heights of the first supporting member 2 and the second supporting member 3 according to actual needs. The structure of the fins themselves can ensure a sufficiently wide range of fin spacing, and provide effective positioning and reinforced support between the fins to prevent occurrence of collapse and adhesion during a furnace welding process.

[0021] In one embodiment, as shown in FIGS. 1-2, the heights of the first supporting member 2 and the second supporting member 3 are equal.

[0022] Since the first supporting member 2 and the second supporting member 3 have the same height, the fin is supported on the first supporting member 2 and the second supporting member 3 of another fin adjacent thereto, which may form support of the same height on both sides of the fin along the second direction, so that the spacing between adjacent fins is consistent, ensuring a good support effect between adjacent fins.

[0023] Certainly, the heights of the first supporting member 2 and the second supporting member 3 may be different. One end of one fin of two adjacent fins along the width direction of the fin body 1 abuts against the first supporting member 2 of the other fin, and the other end of one fin of the two adjacent fins along the width direction of the fin body 1 is engaged with the second supporting member 3 of the other fin, which can enhance a fixation effect between the adjacent fins to ensure positional stability.

[0024] In one embodiment, as shown in FIGS. 1-2, the first supporting member 2 includes a first supporting plate 21 and a first connecting plate 22. One end of the first connecting plate 22 is connected to the fin body 1, and the first supporting plate 21 is connected to the other end of the first connecting plate 22 and is arranged parallel to the fin body 1. The second supporting member 3 includes a second supporting plate 31 and a second connecting plate 32. One end of the second connecting plate 32 is connected to the fin body 1, and the second supporting plate 31 is connected to the other end of the second connecting plate 32 and is arranged parallel to the fin body 1.

[0025] The first supporting plate 21 is formed at a top of the first supporting member 2 or at a top of the second supporting member 3, which can increase a contact area of adjacent fins at a support position, improving the stability and reliability of the support structure.

[0026] In one embodiment, the first connecting plate 22 may be perpendicularly connected to the fin body 1, and the second connecting plate 32 may be perpendicularly connected to the fin body 1. In other words, the first connecting plate 22 extends along the thickness direction of the fin body 1, and the second connecting plate 32 extends along the thickness direction of the fin body 1.

[0027] As shown in FIG. 5, in two adjacent fins, the first supporting plate 21 of the first supporting member 2 of one fin abuts against the fin body 1 of the other fin.

[0028] As shown in FIG. 1, the first supporting plate 21 extends along the length direction of the fin body 1 from the first connecting plate 22, and the second supporting plate 31 extends along the length direction of the fin body 1 from the second connecting plate 32.

[0029] Certainly, in other embodiments, the first supporting plate 21 and the second supporting plate 31 may extend along the width direction of the fin body 1, or along any direction between the length direction and the width direction of the fin body 1.

[0030] In one embodiment, an extension direction of the first supporting plate 21 is either identical or opposite to an extension direction of the second supporting plate 31. When a plurality of fins are stacked, the first supporting plate 21 of one of two adjacent fins abuts against the fin body 1 of the other fin, and the second supporting plate 31 of one fin is clamped to the fin body 1 of the other fin. The first supporting plate 21 and the second supporting plate 31 increase the contact area between the two adjacent fins, thereby improving the structural stability of the assembled adjacent fins.

[0031] As shown in FIG. 1, a plurality of first supporting members 2 are provided and spaced apart along the length direction of the fin body 1. Extension directions of the first supporting plates 21 of adjacent first supporting members 2 are opposite. A plurality of second supporting members 3 are provided and spaced apart along the length direction of the fin body 1. Extension directions of the second supporting plates 31 of adjacent second supporting members 3 are opposite. Extension directions of the second supporting plates 21 on the same fin body 1 are different. In this way, the stability of adjacent fins after being stacked may be enhanced.

[0032] In embodiments of the present disclosure, the extension directions of the first supporting plates 21 of adjacent first supporting members 2 are opposite, the extension directions of the second supporting plates 31 of adjacent second supporting members 3 are opposite, and the extension directions of the first supporting plate 21 on the same fin body 1 are different, which may help to improve the stability of adjacent fins after being stacked.

[0033] Certainly, in other embodiments, extension directions of the first supporting plates 21 of the plurality of first supporting members 2 may also be identical, and extension directions of the second supporting plates 31 of the plurality of second supporting members 3 may also be identical.

[0034] As shown in FIG. 1, the other end of the fin body 1 in the width direction has a drainage structure 14, which has a plurality of folded portions arranged in sequence along the width direction of the fin body 1 to form a corrugated structure. The corrugated structure extends along the length direction of the fin body 1, and the second supporting member 3 is provided on the folded portion of the drainage structure 14 away from the mounting recess 11. The drainage structure 14 is configured to remove water from the fin.

[0035] In embodiments of the present disclosure, by providing the drainage structure 14 and disposing the second supporting member 3 on the drainage structure 14, drainage can be achieved without affecting heat exchange.

[0036] In one embodiment, the mounting recess 11 extends along the width direction of the fin body 1, and is configured to mount a flat tube 100 (as shown in FIG. 6).

[0037] A width direction of the mounting recess 11 is the second direction, which is also the width direction of the flat tube 100. That is, the fin is of a slotted type, and the flat tube 100 may be smoothly inserted into the mounting recess 11 along a direction perpendicular to the length of the fin body 1, achieving engagement and fixation between the flat tube 100 and the fin.

[0038] In one embodiment, the mounting recess 11 is located on a side edge of the fin body 1, and the mounting recess 11 has an open end on its side away from the second supporting member 3.

[0039] By adopting this structure, the flat tube 100 may be inserted from the open end along the second direction. The flat tube 100 fits snugly with the mounting recess 11 through a plane in the length direction, which can reduce the difficulty of assembling the flat tube 100 in the mounting recess 11 and improve the assembly efficiency. In particular, when the flat tube 100 needs to be assembled with a plurality of fins simultaneously, the assembly efficiency can be significantly improved.

[0040] In addition, due to a relatively large depth and length of a notch of the mounting recess 11, a contact area between the flat tube 100 and the mounting recess 11 is increased to enhance an engagement effect between the flat tube 100 and the mounting recess 11.

[0041] It may be understood that in some other embodiments, the mounting recess 11 may be disposed at a position near the side edge of the fin body 1, and the mounting recess 11 does not have an open end. Specifically, the mounting recess 11 is a through-slot structure, and when the flat tube 100 is mounted in the mounting recess 11, the flat tube 100 is inserted into the mounting recess 11 along the third direction.

[0042] It may be understood that since the mounting recess 11 has the open end on the side away from the second supporting member 3, fins may be provided on both sides of the flat tube 100, and openings of the mounting recesses 11 of the fins on both sides are opposite, which may facilitate insertion of the fins from both sides of the flat tube 100, facilitate the engagement fit of the fins with the flat tube 100, reduce the assembly difficulty, and improve the assembly efficiency.

[0043] In one embodiment, as shown in FIGS. 1-2, the fin body 1 is provided with a plurality of third supporting members 4 along a periphery of the mounting recess 11.

[0044] Since the mounting recess 11 serves as a mounting region for the fin body 1 to mount the flat tube 100, the plurality of third supporting members 4 are arranged around the mounting recess 11. When the flat tube 100 is inserted into the mounting recess 11, the plurality of third supporting members 4 may provide effective positioning support for the flat tube 100. Meanwhile, due to the contact between the plurality of third supporting members 4 and the flat tube 100, the contact area between the fin and the flat tube 100 is increased, which can not only effectively prevent the fins from collapsing and sticking together during the furnace welding process, but also increase the heat exchange area of the fins and improve the heat exchange efficiency of the heat exchanger.

[0045] In one embodiment, the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the length direction of the fin body 1; and / or the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the width direction of the fin body 1.

[0046] The arrangement of the plurality of third supporting members 4 on the periphery of the mounting recess 11 is not arbitrary. If the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the first direction, it may enhance the stability of adjacent fins along the first direction when the flat tube 100 is mounted in the mounting recess 11; and / or if the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the second direction, it may enhance the stability of adjacent fins along the second direction when the flat tube 100 is mounted in the mounting recess 11.

[0047] In one embodiment, the third supporting member 4 is of an integral structure or a split structure.

[0048] As shown in FIGS. 1-2, if the third supporting member 4 is of an integral structure, and a width of the third supporting member 4 along the second direction is relatively large, in which case the third supporting member 4 may also be referred to as a wide-profile structure. For example, each mounting recess 11 is surrounded by two third supporting members 4, and the two third supporting members 4 are arranged opposite to each other in the first direction. The contact area between the third supporting member 4 and the fin adjacent thereto is relatively large, which can provide greater support for the adjacent fin. Meanwhile, the contact area between the third supporting member 4 and the flat tube 100 is relatively large, which can improve the heat exchange effect.

[0049] Specifically, when the third supporting member 4 is of an integral structure, a length of the third supporting member 4 along the width direction of the fin body 1 is L, and a width of the mounting recess 11 along the length direction of the fin body 1 is B, in which L = 1 / 2B. The length of the third supporting member 4 along the width direction of the fin body 1 is sized to ensure the structural stability of the third supporting member 4.

[0050] Specifically, when the third supporting member 4 is of a split structure, the third supporting member 4 includes a plurality of sub-supporting members arranged along the width direction of the fin body 1, with a gap between two adjacent sub-supporting members. A dimension of the gap along the width direction of the fin body 1 is A, which is less than 3 mm. The dimension of the gap along the width direction of the fin body 1 is set to effectively ensure the stability while facilitating drainage, making the structure of the third supporting member 4 more flexible.

[0051] FIG. 3 shows a first schematic diagram of another form of the fin according to an embodiment of the present disclosure; FIG. 4 shows a second schematic diagram of another form of the fin according to an embodiment of the present disclosure.

[0052] As shown in FIGS. 3-4, if the third supporting member 4 is of a split structure, the width of the third supporting member 4 along the second direction is relatively small, in which case the third supporting member 4 may also be referred to as a narrow-profile structure. For example, each mounting recess 11 is surrounded by four third supporting members 4, two sets of third supporting members 4 are arranged opposite to each other along the first direction, and each set of third supporting members 4 has two third supporting members 4 arranged opposite to each other along the second direction. In such a case, there are four support points around the mounting recess 11 between two adjacent fins, which improves the positioning and support effect between the two adjacent fins.

[0053] In one embodiment, as shown in FIGS. 1-4, the mounting recess 11 includes two first recess edges 111 arranged opposite to each other and a second recess edge 112 arranged between the two first recess edges 111; the third supporting members 4 are connected to the first recess edges 111.

[0054] Since the third supporting members 4 are provided only on the first recess edges 111, a surface area of the plurality of third supporting members 4 corresponding to the mounting recess 11 is less than or equal to an area of the mounting recess 11, which can fully utilize the cut material at a position where the fin corresponds to the mounting recess 11 to form effective positioning support for the fin. Each of the two second recess edges 112 is provided with the third supporting member 4, which can form more effective positioning support for the flat tube 100, reduce a risk that the fin tips over during installation, and further improve the contact area between the fin and the flat tube 100, thereby enhancing the heat exchange efficiency of the heat exchanger.

[0055] The second recess edge 112 has a circular arc structure, and the second recess edge 112 of the circular arc structure forms a better fit with arc-shaped outer walls on both sides of the flat tube 100 in the width direction, making the engagement between the fin and the flat tube 100 tighter and further improving the heat exchange efficiency between the fin and the flat tube 100.

[0056] In one embodiment, as shown in FIGS. 1-4, a bearing plate 41 is provided on a side of the third supporting member 4 away from the first recess edge 111, and the bearing plate 41 is arranged parallel to the fin body 1.

[0057] The third supporting member 4 is formed by folding the cut material, the bearing plate 41 is disposed at a top of the third supporting member 4, and the bearing plate 41 is a plate-like structure, which can improve the structural stability of the third supporting member 4 for supporting adjacent fins.

[0058] In one embodiment, as shown in FIGS. 1-4, a heat dissipation bridge 12 is provided on the fin body 1, and may be used to form a reinforced heat exchange structure on the fin body 1, thereby improving the heat exchange efficiency of the fin.

[0059] The heat dissipation bridge 12 extends along the length direction of the fin body 1, and a plurality of third supporting members 4 are provided at both ends of the heat dissipation bridge 12. The plurality of supporting members are arranged at both ends of the heat dissipation bridge 12 along the first direction, which is beneficial for improving the support stability.

[0060] In addition, a protrusion 13 is provided on the fin body 1, and may form a reinforced heat exchange structure on the fin body 1, further improving the heat exchange efficiency of the fin.

[0061] In one embodiment, as shown in FIGS. 1-4, an orthographic projection of the heat dissipation bridge 12 on a reference plane at least partially overlaps with an orthographic projection of the first supporting member 2 on the reference plane, in which the reference plane is perpendicular to the length direction of the fin body 1 and parallel to the width direction of the fin body 1. After passing through the first supporting member 2, gas flows towards the heat dissipation bridge 12 and flows out from the second supporting member 3. Before the gas flows into the heat dissipation bridge 12, the first supporting member 2 may cause disturbance to the gas, thereby improving the heat exchange efficiency.

[0062] FIG. 5 shows a schematic diagram of fins in a stacked arrangement according to an embodiment of the present disclosure; FIG. 6 shows a schematic diagram of installation of fins and flat tubes according to an embodiment of the present disclosure.

[0063] As shown in FIGS. 5-6, this embodiment provides a heat exchanger including a flat tube 100 and the aforementioned fin. The flat tube 100 is disposed in the mounting recess 11 of the fin.

[0064] For the heat exchanger according to this embodiment, when the flat tube 100 is snapped into the mounting recess 11, effective support may be formed between adjacent fins through the first supporting member 2 and the second supporting member 3. When the flat tube 100 and the fin are welded by furnace welding, the structural stability of the fin may be enhanced through the first supporting member 2 and the second supporting member 3. With the assistance of the first supporting member 2 and the second supporting member 3 of the fin, a phenomenon of fin collapse and adhesion may be effectively prevented.

[0065] As shown in FIGS. 5 and 6, the heat exchanger includes a plurality of fins arranged along a length direction of the flat tube 100. Two first supporting members 2 of at least some adjacent fins are staggered in the length direction of the fin body 1; and / or, two second supporting members 3 of at least some adjacent fins are staggered in the length direction of the fin body 1.

[0066] In embodiments of the present disclosure, due to the staggered arrangement of the first supporting members 2 and / or the second supporting members 3 of the fins in the length direction, the supporting members may provide support at different positions in the length direction of the fin body 1, which is conducive to improving the stability of the overall structure after the plurality of fins are stacked.

[0067] Further, the first supporting members 2 and / or the second supporting members 3 of the plurality of fins are uniformly staggered in the length direction of the fin body 1, which can further improve the stability of the overall structure after the plurality of fins are stacked.

[0068] It should be noted that the fins shown in the drawings and described in this specification are only examples of using the principles of the present disclosure. It should be clearly understood by those skilled in the art that the principles of the present disclosure are not limited to any details or components of the device shown in the drawings or described in the specification.

On the contrary, these implementations are provided to make the present disclosure comprehensive and complete, and fully convey concepts of the exemplary embodiments to those skilled in the art.

[0014] FIG. 1 shows a first schematic diagram of one form of a fin according to an embodiment of the present disclosure; FIG. 2 shows a second schematic diagram of one form of the fin according to an embodiment of the present disclosure.

[0015] As shown in FIGS. 1-2, this embodiment provides a fin including a fin body 1. The fin body 1 is provided with a plurality of mounting recesses 11 spaced along a length direction of the fin body 1. One end of the fin body 1 in a width direction is provided with a first supporting member 2, and the other end of the fin body 1 in the width direction is provided with a second supporting member 3. The first supporting member 2 and the second supporting member 3 at least partially overlap along the width direction of the fin body 1.

[0016] The fin provided in this embodiment includes the first supporting member 2 and the second supporting member 3 arranged on both sides of the fin body 1 in the width direction, respectively, and the first supporting members 2 and second supporting members 3 can support adjacent fins from both sides of the fin body 1 in the width direction, improving support stability and reliability and effectively solving a problem related to positioning and support between fins. The first supporting member 2 is disposed at one end of the fin body 1 in the width direction, and the second supporting member 3 is disposed at the other end of the fin body 1 in the width direction. When the fins are stacked and mounted, even if they are subjected to external force, the fins will not tilt during the mounting, reducing risks of support loss and damage to the fins.

[0017] It can be understood that the length direction of the fin body 1 is defined as a first direction, which is denoted by D1; the width direction of the fin body 1 is defined as a second direction, which is denoted by D2; a thickness direction of the fin body 1 is defined as a third direction, which is denoted by D3, in which the first direction, the second direction, and the third direction are perpendicular to one another, and they only represent spatial directions and have no substantive meaning.

[0018] In one embodiment, as shown in FIGS. 1-2, the first supporting member 2 and / or the second supporting member 3 are formed by folding a cut material on the fin body 1.

[0019] By directly utilizing surplus material on the fin body 1 to form the first supporting member 2 and the second supporting member 3 of flanged structures, material utilization is improved, eliminating need for additional tooling assistance and effectively saving material costs, and fins with built-in positioning support structures can be formed, facilitating assembly. The first supporting member 2 and the second supporting member 3 may be formed by stamping, which saves material costs, does not require additional tooling, is easy to assemble, and enables large-scale and industrialized production.

[0020] In addition, fin positioning requirements for different spacing can be achieved by selecting heights of the first supporting member 2 and the second supporting member 3 according to actual needs. The structure of the fins themselves can ensure a sufficiently wide range of fin spacing, and provide effective positioning and reinforced support between the fins to prevent occurrence of collapse and adhesion during a furnace welding process.

[0021] In one embodiment, as shown in FIGS. 1-2, the heights of the first supporting member 2 and the second supporting member 3 are equal.

[0022] Since the first supporting member 2 and the second supporting member 3 have the same height, the fin is supported on the first supporting member 2 and the second supporting member 3 of another fin adjacent thereto, which may form support of the same height on both sides of the fin along the second direction, so that the spacing between adjacent fins is consistent, ensuring a good support effect between adjacent fins.

[0023] Certainly, the heights of the first supporting member 2 and the second supporting member 3 may be different. One end of one fin of two adjacent fins along the width direction of the fin body 1 abuts against the first supporting member 2 of the other fin, and the other end of one fin of the two adjacent fins along the width direction of the fin body 1 is engaged with the second supporting member 3 of the other fin, which can enhance a fixation effect between the adjacent fins to ensure positional stability.

[0024] In one embodiment, as shown in FIGS. 1-2, the first supporting member 2 includes a first supporting plate 21 and a first connecting plate 22. One end of the first connecting plate 22 is connected to the fin body 1, and the first supporting plate 21 is connected to the other end of the first connecting plate 22 and is arranged parallel to the fin body 1. The second supporting member 3 includes a second supporting plate 31 and a second connecting plate 32. One end of the second connecting plate 32 is connected to the fin body 1, and the second supporting plate 31 is connected to the other end of the second connecting plate 32 and is arranged parallel to the fin body 1.

[0025] The first supporting plate 21 is formed at a top of the first supporting member 2 or at a top of the second supporting member 3, which can increase a contact area of adjacent fins at a support position, improving the stability and reliability of the support structure.

[0026] In one embodiment, the first connecting plate 22 may be perpendicularly connected to the fin body 1, and the second connecting plate 32 may be perpendicularly connected to the fin body 1. In other words, the first connecting plate 22 extends along the thickness direction of the fin body 1, and the second connecting plate 32 extends along the thickness direction of the fin body 1.

[0027] As shown in FIG. 5, in two adjacent fins, the first supporting plate 21 of the first supporting member 2 of one fin abuts against the fin body 1 of the other fin.

[0028] As shown in FIG. 1, the first supporting plate 21 extends along the length direction of the fin body 1 from the first connecting plate 22, and the second supporting plate 31 extends along the length direction of the fin body 1 from the second connecting plate 32.

[0029] Certainly, in other embodiments, the first supporting plate 21 and the second supporting plate 31 may extend along the width direction of the fin body 1, or along any direction between the length direction and the width direction of the fin body 1.

[0030] In one embodiment, an extension direction of the first supporting plate 21 is either identical or opposite to an extension direction of the second supporting plate 31. When a plurality of fins are stacked, the first supporting plate 21 of one of two adjacent fins abuts against the fin body 1 of the other fin, and the second supporting plate 31 of one fin is clamped to the fin body 1 of the other fin. The first supporting plate 21 and the second supporting plate 31 increase the contact area between the two adjacent fins, thereby improving the structural stability of the assembled adjacent fins.

[0031] As shown in FIG. 1, a plurality of first supporting members 2 are provided and spaced apart along the length direction of the fin body 1. Extension directions of the first supporting plates 21 of adjacent first supporting members 2 are opposite. A plurality of second supporting members 3 are provided and spaced apart along the length direction of the fin body 1. Extension directions of the second supporting plates 31 of adjacent second supporting members 3 are opposite. Extension directions of the second supporting plates 21 on the same fin body 1 are different. In this way, the stability of adjacent fins after being stacked may be enhanced.

[0032] In embodiments of the present disclosure, the extension directions of the first supporting plates 21 of adjacent first supporting members 2 are opposite, the extension directions of the second supporting plates 31 of adjacent second supporting members 3 are opposite, and the extension directions of the first supporting plate 21 on the same fin body 1 are different, which may help to improve the stability of adjacent fins after being stacked.

[0033] Certainly, in other embodiments, extension directions of the first supporting plates 21 of the plurality of first supporting members 2 may also be identical, and extension directions of the second supporting plates 31 of the plurality of second supporting members 3 may also be identical.

[0034] As shown in FIG. 1, the other end of the fin body 1 in the width direction has a drainage structure 14, which has a plurality of folded portions arranged in sequence along the width direction of the fin body 1 to form a corrugated structure. The corrugated structure extends along the length direction of the fin body 1, and the second supporting member 3 is provided on the folded portion of the drainage structure 14 away from the mounting recess 11. The drainage structure 14 is configured to remove water from the fin.

[0035] In embodiments of the present disclosure, by providing the drainage structure 14 and disposing the second supporting member 3 on the drainage structure 14, drainage can be achieved without affecting heat exchange.

[0036] In one embodiment, the mounting recess 11 extends along the width direction of the fin body 1, and is configured to mount a flat tube 100 (as shown in FIG. 6).

[0037] A width direction of the mounting recess 11 is the second direction, which is also the width direction of the flat tube 100. That is, the fin is of a slotted type, and the flat tube 100 may be smoothly inserted into the mounting recess 11 along a direction perpendicular to the length of the fin body 1, achieving engagement and fixation between the flat tube 100 and the fin.

[0038] In one embodiment, the mounting recess 11 is located on a side edge of the fin body 1, and the mounting recess 11 has an open end on its side away from the second supporting member 3.

[0039] By adopting this structure, the flat tube 100 may be inserted from the open end along the second direction. The flat tube 100 fits snugly with the mounting recess 11 through a plane in the length direction, which can reduce the difficulty of assembling the flat tube 100 in the mounting recess 11 and improve the assembly efficiency. In particular, when the flat tube 100 needs to be assembled with a plurality of fins simultaneously, the assembly efficiency can be significantly improved.

[0040] In addition, due to a relatively large depth and length of a notch of the mounting recess 11, a contact area between the flat tube 100 and the mounting recess 11 is increased to enhance an engagement effect between the flat tube 100 and the mounting recess 11.

[0041] It may be understood that in some other embodiments, the mounting recess 11 may be disposed at a position near the side edge of the fin body 1, and the mounting recess 11 does not have an open end. Specifically, the mounting recess 11 is a through-slot structure, and when the flat tube 100 is mounted in the mounting recess 11, the flat tube 100 is inserted into the mounting recess 11 along the third direction.

[0042] It may be understood that since the mounting recess 11 has the open end on the side away from the second supporting member 3, fins may be provided on both sides of the flat tube 100, and openings of the mounting recesses 11 of the fins on both sides are opposite, which may facilitate insertion of the fins from both sides of the flat tube 100, facilitate the engagement fit of the fins with the flat tube 100, reduce the assembly difficulty, and improve the assembly efficiency.

[0043] In one embodiment, as shown in FIGS. 1-2, the fin body 1 is provided with a plurality of third supporting members 4 along a periphery of the mounting recess 11.

[0044] Since the mounting recess 11 serves as a mounting region for the fin body 1 to mount the flat tube 100, the plurality of third supporting members 4 are arranged around the mounting recess 11. When the flat tube 100 is inserted into the mounting recess 11, the plurality of third supporting members 4 may provide effective positioning support for the flat tube 100. Meanwhile, due to the contact between the plurality of third supporting members 4 and the flat tube 100, the contact area between the fin and the flat tube 100 is increased, which can not only effectively prevent the fins from collapsing and sticking together during the furnace welding process, but also increase the heat exchange area of the fins and improve the heat exchange efficiency of the heat exchanger.

[0045] In one embodiment, the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the length direction of the fin body 1; and / or the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the width direction of the fin body 1.

[0046] The arrangement of the plurality of third supporting members 4 on the periphery of the mounting recess 11 is not arbitrary. If the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the first direction, it may enhance the stability of adjacent fins along the first direction when the flat tube 100 is mounted in the mounting recess 11; and / or if the plurality of third supporting members 4 are symmetrically arranged on both sides of the mounting recess 11 along the second direction, it may enhance the stability of adjacent fins along the second direction when the flat tube 100 is mounted in the mounting recess 11.

[0047] In one embodiment, the third supporting member 4 is of an integral structure or a split structure.

[0048] As shown in FIGS. 1-2, if the third supporting member 4 is of an integral structure, and a width of the third supporting member 4 along the second direction is relatively large, in which case the third supporting member 4 may also be referred to as a wide-profile structure. For example, each mounting recess 11 is surrounded by two third supporting members 4, and the two third supporting members 4 are arranged opposite to each other in the first direction. The contact area between the third supporting member 4 and the fin adjacent thereto is relatively large, which can provide greater support for the adjacent fin. Meanwhile, the contact area between the third supporting member 4 and the flat tube 100 is relatively large, which can improve the heat exchange effect.

[0049] Specifically, when the third supporting member 4 is of an integral structure, a length of the third supporting member 4 along the width direction of the fin body 1 is L, and a width of the mounting recess 11 along the length direction of the fin body 1 is B, in which L = 1 / 2B. The length of the third supporting member 4 along the width direction of the fin body 1 is sized to ensure the structural stability of the third supporting member 4.

[0050] Specifically, when the third supporting member 4 is of a split structure, the third supporting member 4 includes a plurality of sub-supporting members arranged along the width direction of the fin body 1, with a gap between two adjacent sub-supporting members. A dimension of the gap along the width direction of the fin body 1 is A, which is less than 3 mm. The dimension of the gap along the width direction of the fin body 1 is set to effectively ensure the stability while facilitating drainage, making the structure of the third supporting member 4 more flexible.

[0051] FIG. 3 shows a first schematic diagram of another form of the fin according to an embodiment of the present disclosure; FIG. 4 shows a second schematic diagram of another form of the fin according to an embodiment of the present disclosure.

[0052] As shown in FIGS. 3-4, if the third supporting member 4 is of a split structure, the width of the third supporting member 4 along the second direction is relatively small, in which case the third supporting member 4 may also be referred to as a narrow-profile structure. For example, each mounting recess 11 is surrounded by four third supporting members 4, two sets of third supporting members 4 are arranged opposite to each other along the first direction, and each set of third supporting members 4 has two third supporting members 4 arranged opposite to each other along the second direction. In such a case, there are four support points around the mounting recess 11 between two adjacent fins, which improves the positioning and support effect between the two adjacent fins.

[0053] In one embodiment, as shown in FIGS. 1-4, the mounting recess 11 includes two first recess edges 111 arranged opposite to each other and a second recess edge 112 arranged between the two first recess edges 111; the third supporting members 4 are connected to the first recess edges 111.

[0054] Since the third supporting members 4 are provided only on the first recess edges 111, a surface area of the plurality of third supporting members 4 corresponding to the mounting recess 11 is less than or equal to an area of the mounting recess 11, which can fully utilize the cut material at a position where the fin corresponds to the mounting recess 11 to form effective positioning support for the fin. Each of the two second recess edges 112 is provided with the third supporting member 4, which can form more effective positioning support for the flat tube 100, reduce a risk that the fin tips over during installation, and further improve the contact area between the fin and the flat tube 100, thereby enhancing the heat exchange efficiency of the heat exchanger.

[0055] The second recess edge 112 has a circular arc structure, and the second recess edge 112 of the circular arc structure forms a better fit with arc-shaped outer walls on both sides of the flat tube 100 in the width direction, making the engagement between the fin and the flat tube 100 tighter and further improving the heat exchange efficiency between the fin and the flat tube 100.

[0056] In one embodiment, as shown in FIGS. 1-4, a bearing plate 41 is provided on a side of the third supporting member 4 away from the first recess edge 111, and the bearing plate 41 is arranged parallel to the fin body 1.

[0057] The third supporting member 4 is formed by folding the cut material, the bearing plate 41 is disposed at a top of the third supporting member 4, and the bearing plate 41 is a plate-like structure, which can improve the structural stability of the third supporting member 4 for supporting adjacent fins.

[0058] In one embodiment, as shown in FIGS. 1-4, a heat dissipation bridge 12 is provided on the fin body 1, and may be used to form a reinforced heat exchange structure on the fin body 1, thereby improving the heat exchange efficiency of the fin.

[0059] The heat dissipation bridge 12 extends along the length direction of the fin body 1, and a plurality of third supporting members 4 are provided at both ends of the heat dissipation bridge 12. The plurality of supporting members are arranged at both ends of the heat dissipation bridge 12 along the first direction, which is beneficial for improving the support stability.

[0060] In addition, a protrusion 13 is provided on the fin body 1, and may form a reinforced heat exchange structure on the fin body 1, further improving the heat exchange efficiency of the fin.

[0061] In one embodiment, as shown in FIGS. 1-4, an orthographic projection of the heat dissipation bridge 12 on a reference plane at least partially overlaps with an orthographic projection of the first supporting member 2 on the reference plane, in which the reference plane is perpendicular to the length direction of the fin body 1 and parallel to the width direction of the fin body 1. After passing through the first supporting member 2, gas flows towards the heat dissipation bridge 12 and flows out from the second supporting member 3. Before the gas flows into the heat dissipation bridge 12, the first supporting member 2 may cause disturbance to the gas, thereby improving the heat exchange efficiency.

[0062] FIG. 5 shows a schematic diagram of fins in a stacked arrangement according to an embodiment of the present disclosure; FIG. 6 shows a schematic diagram of installation of fins and flat tubes according to an embodiment of the present disclosure.

[0063] As shown in FIGS. 5-6, this embodiment provides a heat exchanger including a flat tube 100 and the aforementioned fin. The flat tube 100 is disposed in the mounting recess 11 of the fin.

[0064] For the heat exchanger according to this embodiment, when the flat tube 100 is snapped into the mounting recess 11, effective support may be formed between adjacent fins through the first supporting member 2 and the second supporting member 3. When the flat tube 100 and the fin are welded by furnace welding, the structural stability of the fin may be enhanced through the first supporting member 2 and the second supporting member 3. With the assistance of the first supporting member 2 and the second supporting member 3 of the fin, a phenomenon of fin collapse and adhesion may be effectively prevented.

[0065] As shown in FIGS. 5 and 6, the heat exchanger includes a plurality of fins arranged along a length direction of the flat tube 100. Two first supporting members 2 of at least some adjacent fins are staggered in the length direction of the fin body 1; and / or, two second supporting members 3 of at least some adjacent fins are staggered in the length direction of the fin body 1.

[0066] In embodiments of the present disclosure, due to the staggered arrangement of the first supporting members 2 and / or the second supporting members 3 of the fins in the length direction, the supporting members may provide support at different positions in the length direction of the fin body 1, which is conducive to improving the stability of the overall structure after the plurality of fins are stacked.

[0067] Further, the first supporting members 2 and / or the second supporting members 3 of the plurality of fins are uniformly staggered in the length direction of the fin body 1, which can further improve the stability of the overall structure after the plurality of fins are stacked.
