Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] The fin 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 4 As shown, the fin 100 according to an embodiment of the present invention includes a body 1 and a side fin 2.

[0046] Specifically, see the attached document. Figure 1 and attached Figure 4 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 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.

[0047] Further, see attached document. Figure 6 and attached Figure 7 As shown, the body 1 includes a first reinforcing structure 12, which extends from a portion of the body 1 toward the thickness direction of the body 1 (see attached figure). Figure 7 The body 1 protrudes from one side (as shown in the vertical direction), and a first reinforcing structure 12 is provided between at least two adjacent openings 11. The width direction of the body 1 (see attached figure) Figure 6 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 direction of the fin 100. The side plate 2 includes a second reinforcing structure 21. The second reinforcing structure 21 extends along the length direction of the fin 100 and protrudes from the body 1 along the thickness direction of the body 1.

[0048] It is understandable that by simultaneously providing a first reinforcing structure 12 and a second reinforcing structure 21, where the first reinforcing structure 12 is formed by a portion of the body 1 protruding towards the thickness direction of the body 1, and the second reinforcing structure 21 protrudes from the body 1 along the thickness direction of the body 1, the body 1 and the side fins 2 can be structurally reinforced without changing the width of the fins 100 after mold shaping. This improves the overall structural strength of the fins 100, reduces the possibility of fin deformation, ensures the reliability and stability of the fins 100, and enables the fins 100 to better support and reinforce the heat exchange tubes, thereby improving the overall strength and pressure resistance of the heat exchanger. This also improves the situation where the fins 100 produce a whistling sound in windy weather, enhances the user experience, reduces the user complaint rate, and increases user satisfaction.

[0049] Furthermore, the first reinforcing structure 12 can also disturb the airflow when it flows through, change the direction of airflow, and enable the airflow to fully exchange heat with the heat exchange tube, thereby improving the heat exchange effect of the fins 100.

[0050] It should be noted that the reference appendix Figure 1 and attached Figure 2 As shown, the first reinforcing structure 12 and the second reinforcing structure 21 are in the width direction of the fin 100 (see attached diagram). Figure 1 The fins are spaced apart in the direction b shown, which can prevent deformation of the fins 100 during the manufacturing of the first reinforcing structure 12 or the second reinforcing structure 21, thereby relatively ensuring the structural strength of the fins 100.

[0051] According to the embodiment of this utility model, the fin 100 is provided with a first reinforcing structure 12 and a second reinforcing structure 21. The first reinforcing structure 12 is formed by a portion of the body 1 protruding towards one side of the body 1 in the thickness direction, and the second reinforcing structure 21 protrudes from the body 1 along the thickness direction of the body 1. This allows for structural reinforcement of the body 1 and the side fin 2 without changing the width of the fin 100 while the mold is fixed. This improves the overall structural strength of the fin 100, reduces the possibility of deformation of the fin 100, ensures the reliability and stability of the fin 100, and improves the situation where the fin 100 produces a whistling sound in windy weather. This enhances the user experience, reduces the user complaint rate, and increases user satisfaction.

[0052] In some embodiments of this utility model, reference is made to the appendix. Figure 8As shown, along the width direction of the body 1, the width of the first reinforcing structure 12 is L1, and the width of the second reinforcing structure 21 is L2, and the following condition is met: L1 > L2. Since the width of the body 1 is greater than the width of the side piece 2, the space on the body 1 to set the first reinforcing structure 12 is relatively large. Therefore, the width L1 of the first reinforcing structure 12 is made greater than the width L2 of the second reinforcing structure 21, so that it can match the width of the body 1 and the side piece 2, and ensure the production and processing of the first reinforcing structure 12 and the second reinforcing structure 21.

[0053] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 5 As shown, along the thickness direction of the body 1, the height of the first reinforcing structure 12 protruding from the body 1 is H1, and the height of the second reinforcing structure 21 protruding from the body 1 is H2, and the condition H1 > H2 is satisfied. It can be understood that the setting of the first reinforcing structure 12 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. However, if the height of the second reinforcing structure 21 protruding from the body 1 is too large, it is easy to block the airflow to the body 1. Making the height H1 of the first reinforcing structure 12 protruding from the body 1 greater than the height H2 of the second reinforcing structure 21 protruding from the body 1 can relatively reduce the impact of the second reinforcing structure 21 on the wind resistance and ensure the overall heat exchange performance of the heat exchanger.

[0054] In a further embodiment of this utility model, reference is made to the appendix. Figure 7 As shown, 0.4mm ≤ H1 ≤ 0.8mm serves two purposes. First, it ensures the height of the first reinforcing structure 12 protruding from the body 1 in the thickness direction, thus guaranteeing the structural strength of the first reinforcing structure 12 and its reinforcing effect on the fin 100, thereby improving the structural strength of the fin 100. Second, it prevents the first reinforcing structure 12 from protruding too much from the body 1, avoiding interference with the opening 11 during the manufacturing of the first heat exchange structure. This ensures the integrity of the opening 11, reduces the manufacturing difficulty of the fin 100, and guarantees the manufacturing process of the fin 100. For example, the height H1 of the first reinforcing structure 12 protruding from the body 1 can be 0.4mm, 0.5mm, 0.6mm, 0.7mm, or 0.8mm.

[0055] Further, see attached document. Figure 7As shown, 0.2mm ≤ H2 ≤ 0.5mm serves two purposes. First, it ensures that the second reinforcing structure 21 protrudes above the body 1 in the thickness direction, thus guaranteeing the structural strength of the second reinforcing structure 21 and its reinforcing effect on the fins 100, thereby improving the structural strength of the fins 100. Second, it prevents the second reinforcing structure 21 from protruding too much from the body 1, avoiding obstruction of airflow to the body 1 when airflow passes through the second reinforcing structure 21, reducing the impact of the second reinforcing structure 21 on wind resistance, and ensuring the overall heat exchange performance of the heat exchanger. For example, the height H2 of the second reinforcing structure 21 protruding from the body 1 can be 0.2mm, 0.3mm, 0.4mm, or 0.5mm.

[0056] In some embodiments of this utility model, reference is made to the appendix. Figure 2 and attached Figure 3 As shown, the first reinforcing structure 12 and the second reinforcing structure 21 protrude in the same or opposite directions along the thickness direction of the body 1. Both can improve the structural strength of the fin 100, reduce the possibility of deformation of the fin 100, ensure the reliability and stability of the fin 100, thereby improving the situation of the fin 100 producing a whistling sound in windy weather, improving the user experience, reducing the user complaint rate, and improving user satisfaction.

[0057] In some embodiments of this utility model, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 9 and attached Figure 10 As shown, the first reinforcing structure 12 includes multiple first protrusions 121 arranged in the width direction of the body 1. The arrangement of multiple first protrusions 121 can further improve the structural strength of the body 1, reduce the possibility of deformation of the body 1, thereby improving the overall structural strength of the fin 100, ensuring the reliability and stability of the fin 100, and thus improving the situation of the fin 100 producing a whistling sound in windy weather, improving the user experience, reducing the user complaint rate, and increasing user satisfaction. For example, there can be two, three, or four first protrusions 121 arranged in the width direction of the body 1.

[0058] In a further embodiment of this utility model, reference is made to the appendix. Figure 1 and attached Figure 9 As shown, the first reinforcing structure 12 is symmetrically arranged about the line connecting the centers of two adjacent openings 11, which facilitates the production and processing of the fins 100, ensures the structural strength balance of the body 1 in the width direction, and makes the airflow disturbance effect on both sides of the heat exchange tube along the width direction of the body 1 the same, ensuring that the heat exchange effect on both sides of the heat exchange tube along the width direction of the body 1 is the same.

[0059] In a further embodiment of this utility model, reference is made to the appendix. Figure 10As shown, in conjunction with the appendix Figure 9 In the direction from the fixed end to the free end of the first protrusion 121, the width of the first protrusion 121 gradually decreases. On the one hand, this can ensure the reliability of the connection between the first protrusion 121 and other parts of the body 1, and ensure the structural strengthening effect of the first protrusion 121 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.

[0060] In a further embodiment of this utility model, reference is made to the appendix. Figure 10 As shown, in conjunction with the appendix Figure 9 In the width direction of the body 1, two adjacent first protrusions 121 are connected at one end facing each other, so that the first reinforcing structure 12 between two adjacent openings 11 is formed into a corrugated structure. The extension direction of the corrugated structure is the width direction of the body 1. The first reinforcing structure 12 of the corrugated structure is simple to form, has few process steps, and has reliable strength. The corrugated structure design can increase the structural strength of the fin 100, ensure the reliability and stability of the fin 100, and thus improve the situation of the fin 100 producing a whistling sound in windy weather, improve the user experience, reduce the user complaint rate, and improve user satisfaction.

[0061] Preferably, refer to the appendix Figure 10 As shown, along the thickness direction of the body 1, the height of the first reinforcing structure 12 protruding from the body 1 is H1. Since the length of the first protrusion 121 in the length direction of the body 1 remains consistent from the center of the opening 11 to the side plate 2, the possibility of interference between the first protrusion 121 and the opening 11 is relatively small. Therefore, H1 can satisfy: 0.4mm≤H1≤1.2mm. On the one hand, this can better ensure the height of the first reinforcing structure 12 protruding from the body 1 in the thickness direction of the body 1, ensure the structural strength of the first reinforcing structure 12, ensure the reinforcing effect of the first reinforcing structure 12 on the fin 100, and improve the structural strength of the fin 100. On the other hand, it can disturb the airflow when the airflow passes through, change the flow direction of the airflow, so that the airflow can better exchange heat with the heat exchange tube and improve the heat exchange effect of the fin 100. For example, the height H1 of the first reinforcing structure 12 protruding from the body 1 can be 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm or 1.2mm.

[0062] In a further embodiment of this utility model, reference is made to the appendix. Figure 4As shown, in the direction from the center of the opening 11 to the side plate 2, the length of the first protrusion 121 gradually increases in the length direction of the body 1, so that the shape of the first protrusion 121 can match the shape of the opening 11, so as to better utilize the space between two adjacent openings 11, maximize the structural reinforcement effect of the first protrusion 121 on the body 1, and enhance the heat exchange reinforcement effect of the first protrusion 121 on the heat exchange tube.

[0063] In a further embodiment of this utility model, reference is made to the appendix. Figure 5 As shown, on any cross section perpendicular to the length direction of the fin 100, the first protrusion 121 is rectangular, which facilitates the manufacturing of the first protrusion 121, reduces the manufacturing difficulty of the fin 100, and ensures the manufacturing of the fin 100.

[0064] 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 second reinforcing structure 21 is inclined toward 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 second reinforcing structure 21 can be inclined toward 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, thereby improving the situation of fin 100 producing whistling sound in windy weather, improving user experience, reducing user complaint rate, and improving user satisfaction.

[0065] 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 second 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 second reinforcing structure 21 has a better reinforcing effect on the fin 100.

[0066] In some embodiments of this utility model, reference is made to the appendix. Figure 5 Appendix Figure 7 and attached Figure 8 As shown, the second reinforcing structure 21 is formed as a second protrusion 211 protruding on one side of the side plate 2 towards the thickness direction of the body 1. It can improve the structural strength of the fin 100, reduce the possibility of deformation of the fin 100, ensure the reliability and stability of the fin 100, and thus improve the situation of the fin 100 producing a whistling sound in windy weather, improve the user experience, reduce the user complaint rate, and improve user satisfaction.

[0067] In a further embodiment of this utility model, reference is made to the appendix. Figure 5 and attached Figure 7 As shown, the width of the second protrusion 211 gradually decreases from the fixed end to the free end. On the one hand, this can ensure the reliability of the connection between the second protrusion 211 and other parts of the side plate 2, and ensure the structural strengthening effect of the second protrusion 211 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.

[0068] In a further embodiment of this utility model, reference is made to the appendix. Figure 5 Appendix Figure 7 and attached Figure 8 As shown, on any cross-section perpendicular to the length direction of the fin 100, the second protrusion 211 can be semi-circular, triangular, or trapezoidal, and 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 second reinforcing structure 21. Of course, this utility model is not limited to this, and the second protrusion 211 can also be other polygons, which are not limited here.

[0069] For example, such as Figure 7 As shown, when the second protrusion 211 is triangular in any cross section perpendicular to the length direction of the fin 100, the free end of the second protrusion 211 is a pointed tip, 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 second protrusion 211 is small, the second protrusion 211 has a limited impact on wind resistance and therefore will not affect the overall performance of the heat exchanger.

[0070] The following is for reference. Figures 1 to 10 The following description describes the fin 100 according to six specific embodiments of the present invention. It is worth understanding that the following description is merely exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0071] Example 1

[0072] Specifically, if Figure 1 and Figure 2 As shown, the fin 100 includes: a body 1 and side fins 2.

[0073] Furthermore, the body 1 extends along the length of the fin 100, and the body 1 is provided with an opening 11 for inserting a heat exchange tube. The opening 11 is provided in multiple spaces along the length of the body 1. The arrangement of multiple openings 11 can meet the need to avoid the heat exchange tube, play a positioning role for the heat exchange tube, facilitate the assembly of the heat exchange tube onto the fin 100, and avoid interference between the heat exchange tube and the fin 100.

[0074] Furthermore, the body 1 includes a first reinforcing structure 12, which is formed by a portion of the body 1 protruding towards one side of the body 1 in the thickness direction. The first reinforcing structure 12 is provided between at least two adjacent openings 11. The first reinforcing structure 12 is symmetrically arranged about the line connecting the centers of the two adjacent openings 11 and includes a plurality of first protrusions 121. The plurality of first protrusions 121 are arranged in the width direction of the body 1. In the direction from the center of the opening 11 to the side plate 2, the length of the first protrusion 121 gradually increases in the length direction of the body 1. On any cross section perpendicular to the length direction of the fin 100, the first protrusion 121 is rectangular, which facilitates the manufacturing of the first protrusion 121, reduces the manufacturing difficulty of the fin 100, and ensures the manufacturing of the fin 100.

[0075] Furthermore, both ends of the body 1 in the width direction are connected to side plates 2. The side plates 2 extend along the length direction of the fin 100. The side plates 2 include a second reinforcing structure 21. The second reinforcing structure 21 extends along the length direction of the fin 100. The second reinforcing structure 21 protrudes from the body 1 in the thickness direction of the body 1 and the protrusion direction is the same as that of the first reinforcing structure 12. In the direction from the body 1 to the side plates 2, the second reinforcing structure 21 is inclined towards the upper side of the body 1, which can improve the structural strength of the fin 100, reduce the possibility of deformation of the fin 100, ensure the reliability and stability of the fin 100, and thus improve the situation of the fin 100 producing a whistling sound in windy weather, improve the user experience, reduce the user complaint rate, and improve user satisfaction.

[0076] In addition, along the width direction of the body 1, the width of the first reinforcing structure 12 is L1, and the width of the second reinforcing structure 21 is L2, where L1 > L2. Along the thickness direction of the body 1, the height of the first reinforcing structure 12 protruding from the body 1 is H1, and the height of the second reinforcing structure 21 protruding from the body 1 is H2, where H1 > H2, 0.4mm ≤ H1 ≤ 0.8mm, and 0.2mm ≤ H2 ≤ 0.5mm. This ensures the production and processing of the fins 100, ensures the structural reinforcement effect of the first reinforcing structure 12 and the second reinforcing structure 21 on the fins 100, and ensures the heat exchange performance of the heat exchanger.

[0077] Example 2

[0078] like Figure 3As shown, this embodiment is basically the same as embodiment one, wherein the same components are given the same names and markings. The difference between embodiment two and embodiment one is that the first reinforcing structure 12 and the second reinforcing structure 21 protrude in opposite directions along the thickness direction of the body 1, and the second reinforcing structure 21 is inclined toward the lower side of the thickness direction of the body 1.

[0079] Example 3

[0080] like Figure 4 and Figure 5 As shown, this embodiment is basically the same as embodiment one, wherein the same components are given the same names and markings. The difference between embodiment three and embodiment one is that the second reinforcing structure 21 is formed as a semi-circular protrusion on the side plate 2 protruding towards the thickness direction of the body 1. In the direction from the fixed end to the free end of the second protrusion 211, the width of the second protrusion 211 gradually decreases.

[0081] Example 4

[0082] like Figure 6 and Figure 7 As shown, this embodiment is basically the same as embodiment three, wherein the same components are given the same names and markings. The only difference between embodiment four and embodiment three is that the second reinforcing structure 21 is formed as a triangular protrusion on the side plate 2 protruding towards the thickness direction of the body 1.

[0083] Example 5

[0084] like Figure 8 As shown, this embodiment is basically the same as embodiment three. The same components are given the same names and markings. The only difference between embodiment five and embodiment three is that the second reinforcing structure 21 is formed as a trapezoidal protrusion on the side plate 2 that protrudes toward the thickness direction of the body 1.

[0085] Example 6

[0086] like Figure 9 and Figure 10As shown, this embodiment is basically the same as embodiment four, wherein the same components are named and marked with the same names. The difference between embodiment six and embodiment four is only that the width of the first protrusion 121 gradually decreases in the direction from the fixed end to the free end of the first protrusion 121. In the width direction of the body 1, the ends of two adjacent first protrusions 121 facing each other are connected, thereby making the first reinforcing structure 12 between two adjacent openings 11 form a corrugated structure. The extension direction of the corrugated structure is the width direction of the body 1. The first reinforcing structure 12 of the corrugated structure is simple to form, has few process steps, and has reliable strength. The corrugated structure design can increase the structural strength of the fin 100, ensure the reliability and stability of the fin 100, and thus improve the situation of the fin 100 producing a whistling sound in windy weather, improve the user experience, reduce the user complaint rate, and improve user satisfaction.

[0087] Furthermore, the height H1 of the first reinforcing structure 12 protruding from the body 1 satisfies: 0.4mm≤H1≤1.2mm. On the one hand, this can better ensure the height of the first reinforcing structure 12 protruding from the body 1 in the thickness direction of the body 1, ensuring the structural strength of the first reinforcing structure 12, ensuring the reinforcing effect of the first reinforcing structure 12 on the fin 100, and improving the structural strength of the fin 100. On the other hand, it can disturb the airflow when the airflow passes through, change the flow direction of the airflow, so that the airflow can better and more fully exchange heat with the heat exchange tube, and improve the heat exchange effect of the fin 100.

[0088] This utility model also proposes a heat exchanger having the fins 100 described in the above embodiments.

[0089] According to the heat exchanger of this utility model embodiment, by providing the above-mentioned fins 100, and by simultaneously providing a first reinforcing structure 12 and a second reinforcing structure 21, the first reinforcing structure 12 is formed by a portion of the body 1 protruding towards one side of the body 1 in the thickness direction, and the second reinforcing structure 21 protrudes from the body 1 along the thickness direction of the body 1, the body 1 and the side fins 2 can be structurally reinforced without changing the width of the fins 100 after mold shaping, thereby improving the overall structural strength of the fins 100, reducing the possibility of fin deformation, ensuring the reliability and stability of the fins 100, and thus improving the situation of the fins 100 producing a whistling sound in windy weather, improving the user experience, reducing the user complaint rate, and improving user satisfaction.
