[0042] The fin 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0043] like Figure 1 and Figure 7 As shown, the fin 100 according to an embodiment of the present invention includes a body 1 and a side fin 2.

[0044] Specifically, see the attached document. Figure 1 As shown, the body 1 extends along the length of the fin 100 (see attached diagram). Figure 1 Extending in the direction shown (a), the width of body 1 (see attached diagram) extends... Figure 2 At least one end of the fin 100 in direction b is connected to a side plate 2. The side plate 2 extends along the length of the fin 100. The side plate 2 includes a reinforcing structure 21, which extends along the thickness direction of the body 1 (see attached figure). Figure 2 The reinforcing structure 21 extends along the length of the fin 100 (as shown in the vertical direction) and protrudes from the body 1. By providing the reinforcing structure 21, the structural strength of the side fin 2 can be improved, the possibility of deformation of the side fin 2 can be reduced, thereby improving the structural strength of the fin 100, improving the problem of low strength caused by excessive perforation of the fin 100, ensuring the reliability and stability of the fin 100, reducing the possibility of fin defects, improving user experience, increasing user satisfaction, reducing user complaint rate, and effectively reducing the probability of fin tipping, improving the anti-tipping ability of the fin 100, improving the tipping phenomenon of the fin 100, ensuring the efficiency of the heat exchanger frame, and improving the production efficiency of the heat exchanger.

[0045] According to the embodiment of this utility model, the fin 100 includes a reinforcing structure 21 in the side plate 2. The reinforcing structure 21 protrudes from the body 1 along the thickness direction of the body 1 and extends along the length direction of the fin 100. This can improve the structural strength of the side plate 2, reduce the possibility of deformation of the side plate 2, improve the structural strength of the fin 100, improve the problem of low strength caused by excessive perforation of the fin 100, ensure the reliability and stability of the fin 100, reduce the possibility of fin defects, improve user experience, increase user satisfaction, reduce user complaint rate, and effectively reduce the probability of fin 100 tipping over, improve the anti-tipping ability of the fin 100, and improve the tipping phenomenon of the fin 100.

[0046] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 4As shown, the width of the reinforcing structure 21 along the width direction of the body 1 is L, and satisfies: 0.4mm ≤ L ≤ 4mm. This ensures that the reinforcing structure 21 occupies sufficient space on the side plate 2, and that the height of the reinforcing structure 21 in the thickness direction of the body 1 is within the required range. This guarantees the structural strength of the reinforcing structure 21, ensures its reinforcing effect on the fin 100, improves the structural strength of the fin 100, reduces the possibility of fin deformation, and ensures the reliability and stability of the fin 100. For example, the width L of the reinforcing structure 21 in the width direction of the body 1 can be 0.4mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm.

[0047] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, in the direction from the body 1 to the side piece 2, the reinforcing structure 21 is inclined towards one side of the body 1 in the thickness direction. It can be understood that, in the direction from the body 1 to the side piece 2, the reinforcing structure 21 can be inclined towards the upper side of the body 1 (e.g., Figure 2 (As shown) tilted, or it can be tilted towards the lower side of body 1 (as shown) Figure 3 As shown, tilting can improve the structural strength of fin 100, reduce the possibility of fin 100 deformation, ensure the reliability and stability of fin 100, reduce the possibility of fin 100 producing bark, improve user experience, and reduce user complaint rate.

[0048] Preferably, refer to the appendix Figure 2 As shown, when testing the fin 100, one end of the fin 100 along its length is fixed, while the other end is in a free state. Under the action of gravity, the bending direction of the reinforcing structure 21, which is inclined toward the upper side of the body 1, is opposite to the direction of gravity. This makes the deformation of the fin 100, which is inclined toward the upper side of the body 1, smaller, and the reinforcing structure 21 has a better reinforcing effect on the fin 100.

[0049] In a further embodiment of this utility model, reference is made to the appendix. Figure 2 and attached Figure 3As shown, the angle between the reinforcing structure 21 and the body 1 is A, and satisfies: 20°≤A≤35°. On the one hand, this ensures that the reinforcing structure 21 protrudes beyond the body 1 in the thickness direction, preventing the angle between the reinforcing structure 21 and the body 1 from being too small, thus ensuring the structural strength of the reinforcing structure 21 and its reinforcing effect on the fins 100, thereby improving the structural strength of the fins 100. On the other hand, this avoids the reinforcing structure 21 protruding beyond the body 1 too much due to an excessively large angle between the reinforcing structure 21 and the body 1, preventing the airflow from being blocked when passing through the reinforcing structure 21, reducing the impact of the reinforcing structure 21 on wind resistance, and ensuring the overall heat exchange performance of the heat exchanger. For example, the angle A between the reinforcing structure 21 and the body 1 can be 20°, 22°, 25°, 29°, 30°, 33°, or 35°.

[0050] In some embodiments of this utility model, reference is made to the appendix. Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the reinforcing structure 21 is formed as a protrusion on the side plate 2 facing the thickness direction of the body 1, which can improve the structural strength of the fin 100, reduce the possibility of fin deformation, ensure the reliability and stability of the fin 100, reduce the possibility of fin defects, improve user experience, and reduce user complaint rate.

[0051] In a further embodiment of this utility model, reference is made to the appendix. Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the width of the protrusion gradually decreases from the fixed end to the free end. On the one hand, this can ensure the reliability of the connection between the protrusion and other parts of the side plate 2, and ensure the structural strengthening effect of the protrusion on the fin 100. On the other hand, it can break the velocity boundary layer formed when the airflow passes over the fin 100 to a certain extent, thereby improving the heat transfer performance of the fin 100 while improving the structural strength of the fin 100.

[0052] In a further embodiment of this utility model, reference is made to the appendix. Figure 4 , Attachment Figure 5 and attached Figure 6As shown, on any cross-section perpendicular to the length direction of the fin 100, the protrusion can be semi-circular, triangular, or trapezoidal, which can be set according to actual conditions to meet different usage requirements. This facilitates optimization of the structural strength and manufacturing convenience of the fin 100, thereby ensuring the reliability of the fin 100. It should be noted that the semi-circle can be half of a perfect circle or half of an ellipse. Preferably, the triangle is an isosceles triangle, and the trapezoid is an isosceles trapezoid, which makes the protrusion have better stability and further improves the structural reliability of the reinforcing structure 21. Of course, this utility model is not limited to this; the protrusion can also be other polygons, and no further restrictions are imposed here.

[0053] For example, such as Figure 5 As shown, when the protrusion is triangular in any cross section perpendicular to the length direction of the fin 100, the free end of the protrusion is a sharp point, which can more significantly break the velocity boundary layer formed when the airflow passes over the fin 100. This can improve the heat transfer performance of the fin 100 while increasing the structural strength of the fin 100. Furthermore, because the height of the protrusion is small, the protrusion has a limited impact on wind resistance and therefore will not affect the overall performance of the heat exchanger.

[0054] In a further embodiment of this utility model, reference is made to the appendix. Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, along the thickness direction of the body 1, the height of the protrusion protruding from the body 1 is H, and it satisfies: 0.2mm ≤ H ≤ 0.5mm. On the one hand, this ensures that the height of the protrusion protruding from the body 1 in the thickness direction guarantees the structural strength of the reinforcing structure 21, ensures the reinforcing effect of the reinforcing structure 21 on the fins 100, and improves the structural strength of the fins 100. On the other hand, it avoids the protrusion from the body 1 being too large, thus preventing the airflow from being blocked when the airflow passes through the reinforcing structure 21, reducing the impact of the reinforcing structure 21 on wind resistance, and ensuring the overall heat exchange performance of the heat exchanger. For example, the height H of the protrusion protruding from the body 1 can be 0.2mm, 0.3mm, 0.4mm, or 0.5mm.

[0055] In some embodiments of this utility model, reference is made to the appendix. Figure 7 , Attachment Figure 8 and attached Figure 9As shown, multiple reinforcing structures 21 on the same side plate 2 are arranged along the width direction of the body 1. These multiple reinforcing structures 21 are spaced apart along the width direction of the body 1. The arrangement of multiple reinforcing structures 21 can further improve the structural strength of the side plate 2, reduce the possibility of deformation of the side plate 2, and thus improve the structural strength of the fin 100. This addresses the problem of low strength caused by excessive perforation in the fin 100, ensures the reliability and stability of the fin 100, reduces the possibility of fin defects, improves user experience, and reduces user complaint rates. For example, the reinforcing structures 21 on the same side plate 2 can be two, three, or four arranged along the width direction of the body 1.

[0056] It should be noted that multiple reinforcing structures 21 on the same side piece 2 can adopt the same form or different forms. For example, there may be two reinforcing structures 21 on the same side piece 2, namely the first reinforcing structure 211 and the second reinforcing structure 212, as shown below. Figure 8 As shown, the first reinforcing structure 211 is formed as a triangular protrusion on the side plate 2 protruding towards the thickness direction of the body 1, and the second reinforcing structure 212 is inclined towards the thickness direction of the body 1 in the direction from the body 1 to the side plate 2; as Figure 9 As shown, the first reinforcing structure 211 is formed as a triangular protrusion on the side plate 2 protruding towards the thickness direction of the body 1, and the second reinforcing structure 212 is formed as a semi-circular protrusion on the side plate 2 protruding towards the thickness direction of the body 1.

[0057] In a further embodiment of this utility model, reference is made to the appendix. Figure 4 and attached Figure 9 As shown, the side plate 2 also includes a first segment 22 and a second segment 23. Both the first segment 22 and the second segment 23 extend along the length direction of the fin 100 and are respectively connected to both ends of the width direction of the reinforcing structure 21. The end of the first segment 22 facing away from the reinforcing structure 21 is connected to the body 1. The first segment 22 is coplanar with the body 1, and the second segment 23 is coplanar with or parallel to the body 1 and spaced apart. The arrangement of the first segment 22 can connect the reinforcing structure 21 and the body 1, which can avoid deformation of the body 1 when manufacturing the reinforcing structure 21, thereby relatively ensuring the structural strength of the fin 100. The arrangement of the second segment 23 can ensure the forming of the reinforcing structure 21, ensure the production and processing of the side plate 2, and reduce the production and processing difficulty of the fin 100.

[0058] It is understandable that the first segment 22, the reinforcing structure 21, and the second segment 23 are arranged sequentially in the direction from the body 1 to the side piece 2. When the reinforcing structure 21 is tilted towards the side of the body 1 in the thickness direction in the direction from the body 1 to the side piece 2, as... Figure 2 and Figure 3As shown, the first segment 22 is coplanar with the body 1, and the second segment 23 is parallel to the body 1; when the reinforcing structure 21 is formed as a protrusion on the side plate 2 protruding towards the thickness direction of the body 1, as... Figure 4 , Figure 5 and Figure 6 As shown, the first segment 22 and the second segment 23 are both coplanar with the body 1. Whether the second segment 23 is coplanar with or parallel to the body 1 depends on the shape of the reinforcing structure 21.

[0059] In a further embodiment of this utility model, reference is made to the appendix. Figure 8 and attached Figure 9 As shown, two adjacent reinforcing structures 21 are spaced apart, and the side plate 2 also includes a third segment 24, which extends along the length direction of the fin 100 and the width direction (see attached figure). Figure 8 The two ends of the b direction shown are respectively connected to the two adjacent reinforcing structures 21 of the same side plate 2. The third segment 24 is coplanar or parallel to the body 1 and spaced apart. The setting of the third segment 24 can connect the two adjacent reinforcing structures 21, ensure that the two adjacent reinforcing structures 21 are spaced apart, avoid interference between the two adjacent reinforcing structures 21 during the production and processing of the fin 100, avoid deformation of the reinforcing structure 21, and further ensure the structural strength of the fin 100.

[0060] It should be noted that when a reinforcing structure 21 is provided on the same side piece 2, refer to the attached document. Figure 4 As shown, the side piece 2 includes a reinforcing structure 21, a first segment 22, and a second segment 23. The first segment 22 is connected to one end of the body 1 in the width direction. The first segment 22, the reinforcing structure 21, and the second segment 23 are arranged sequentially in the direction from the body 1 to the side piece 2. When two reinforcing structures 21 are provided on the same side piece 2, the two reinforcing structures 21 are respectively the first reinforcing structure 211 and the second reinforcing structure 212. (Refer to the attached diagram.) Figure 9 As shown, the side piece 2 includes a first reinforcing structure 211, a second reinforcing structure 212, a first segment 22, a second segment 23 and a third segment 24. The first segment 22 is connected to one end of the body 1 in the width direction. In the direction from the body 1 to the side piece 2, the first segment 22, the first reinforcing structure 211, the third segment 24, the second reinforcing structure 212 and the second segment 23 are arranged in sequence.

[0061] In some embodiments of this utility model, reference is made to the appendix. Figure 1 and attached Figure 7 As shown, the main body 1 has an opening 11 for inserting a heat exchange tube. The opening 11 is along the length of the main body 1 (see attached figure). Figure 1 The multiple openings 11 arranged at intervals in the direction shown in a can meet the requirements of avoiding the heat exchange tubes, and play a positioning role for the heat exchange tubes, so as to facilitate the assembly of the heat exchange tubes onto the fins 100 and avoid interference between the heat exchange tubes and the fins 100.

[0062] Further, see attached document. Figure 1 and attached Figure 2 As shown, the body 1 is also provided with a heat exchange strengthening structure 12. At least two adjacent openings 11 are provided with a heat exchange strengthening structure 12. The heat exchange strengthening structure 12 protrudes from the body 1 along the thickness direction of the body 1. It can disturb the airflow when the airflow passes through, change the flow direction of the airflow, so that the airflow can fully exchange heat with the heat exchange tube and improve the heat exchange effect of the fins 100.

[0063] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 2 As shown, the heat exchange enhancement structure 12 includes multiple bridge plates 121, which are spaced apart along the width direction of the body 1. Each bridge plate 121 extends along the length direction of the body 1. (Refer to the attached diagram) Figure 1 Both ends of the bridge plate 121 (in direction a) are connected to the main body 1, and the middle part is spaced apart from the main body 1. The bridge plate 121 includes a top plate structure and a corresponding support structure. The top plate structure is hollowed out at a position perpendicular to the main body 1, and the position on the main body 1 where the bridge plate 121 is set is also hollowed out. By setting the bridge plate 121, the airflow can be disturbed when the airflow passes over the fin 100, changing the flow direction of the airflow, so that the airflow can fully exchange heat with the heat exchange tube, further improving the heat exchange effect of the fin 100. The more bridge plates 121 there are, the better the heat exchange effect of the fin 100. In addition, the setting of the bridge plate 121 can also play a certain role in improving the structural strength of the fin 100.

[0064] Further, see attached document. Figure 3 As shown, along the thickness direction of the body 1, the bridge plate 121 protrudes from the body 1 by a height M, satisfying: 0.4mm ≤ M ≤ 0.8mm. This ensures the bridge plate 121's effect on airflow disturbance, guarantees the heat exchange effect of the fins 100, and prevents interference between adjacent fins 100 due to excessive protrusion height of the bridge plate 121. For example, the height M of the bridge plate 121 protruding from the body 1 can be 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8mm.

[0065] It should be noted that the multiple bridge plates 121 are symmetrically arranged about the line connecting the centers of two adjacent openings 11, which facilitates the production and processing of the fins 100, makes the airflow disturbance effect on both sides of the heat exchange tube along the width direction of the body 1 the same, and ensures that the heat exchange effect on both sides of the heat exchange tube along the width direction of the body 1 is the same.

[0066] In a further embodiment of this utility model, reference is made to the appendix. Figure 2As shown, the inner wall of the opening 11 is provided with a flange 111 that bends toward the thickness direction of the body 1. The flange 111 extends along the circumferential direction of the opening 11. The flange 111 can guide and position the heat exchange tube when it is assembled onto the fin 100, which facilitates the assembly of the heat exchange tube and reduces the possibility of the heat exchange tube shaking in the opening 11.

[0067] The following is for reference. Figures 1 to 9 The description of the fin 100 according to seven specific embodiments of the present invention is intended to explain the present invention and should not be construed as limiting the present invention.

[0068] Example 1

[0069] Specifically, if Figure 1 and Figure 2 As shown, the fin 100 includes: a body 1 and side fins 2.

[0070] Furthermore, the body 1 extends along the length direction of the fins 100, and the body 1 is provided with openings 11 for inserting heat exchange tubes. Multiple openings 11 are spaced apart along the length direction of the body 1. The inner wall of the opening 11 is provided with a flange 111 bent toward the thickness direction of the body 1. The flange 111 extends along the circumferential direction of the opening 11. The flange 111 can guide and position the heat exchange tube when it is assembled onto the fins 100, which facilitates the assembly of the heat exchange tube and reduces the possibility of the heat exchange tube shaking in the opening 11.

[0071] Furthermore, the body 1 is also provided with a heat exchange enhancement structure 12. At least two adjacent openings 11 are provided with a heat exchange enhancement structure 12. The heat exchange enhancement structure 12 includes a plurality of bridge plates 121. The plurality of bridge plates 121 are spaced apart along the width direction of the body 1. The bridge plates 121 protrude from the body 1 along the thickness direction of the body 1. They can disturb the airflow when the airflow passes through, change the flow direction of the airflow, so that the airflow can fully exchange heat with the heat exchange tube and improve the heat exchange effect of the fins 100.

[0072] Furthermore, both ends of the body 1 in the width direction are connected to side plates 2. The side plates 2 include a reinforcing structure 21, a first segment 22 and a second segment 23.

The two ends of the first segment 22 in the width direction are connected to the body 1 and the reinforcing structure 21 respectively. The first segment 22 is coplanar with the body 1. In the direction from the body 1 to the side plate 2, the reinforcing structure 21 is inclined towards the upper side in the thickness direction of the body 1. The second segment 23 is connected to the end of the reinforcing structure 21 that is away from the first segment 22 and is parallel to the body 1.

This ensures that the reinforcing structure 21 occupies sufficient space on the side plate 2, and that the height of the reinforcing structure 21 in the thickness direction of the body 1 is within the required range. This guarantees the structural strength of the reinforcing structure 21, ensures the reinforcing effect of the reinforcing structure 21 on the fin 100, improves the structural strength of the fin 100, reduces the possibility of deformation of the fin 100, and ensures the reliability and stability of the fin 100.
