Description

Technical Field

[0001] This utility model relates to the field of radiator fins, and in particular to a parallel flow transverse insertion fin with positioning function. Background Technology

[0002] Radiator fins are the parts of a radiator used to increase the heat dissipation area and improve heat dissipation efficiency. They are usually a series of thin fins that accelerate heat dissipation by increasing the heat dissipation surface area. Radiator fins are widely used in various heat dissipation applications, such as automotive radiators, electronic device radiators, air conditioner radiators, and refrigerator radiators.

[0003] Horizontal insert fins are assembled by directly inserting them into flat tubes. However, the insertion depth of each fin may vary, resulting in uneven layering in the width direction, affecting aesthetics. Furthermore, the fins may have different tilt angles, meaning they may not be parallel to each other, leading to inconsistent fin spacing. In some cases, they may even be tilted together with one end touching, affecting airflow between the fins and reducing heat exchange efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a parallel flow transverse insert fin with positioning function, which solves the problems of easy contact and unevenness between stacked fins.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a parallel flow transverse insertion fin with width positioning function, comprising a fin body having a trapezoidal cross-section with a window angle of 30°, a flat tube insertion hole provided in the center of the fin body for inserting a flat tube, and a spacing structure I provided at the stacking interface of the fin body, the spacing structure I comprising: an arc-shaped bend, a cavity, and a layered bend; the arc-shaped bend is located at the edge of the fin body to reduce airflow resistance and enhance structural strength; the cavity is formed inside the fin body to reduce weight and improve heat exchange efficiency; the layered bend is located on the rear surface of the fin body to maintain a predetermined spacing between fins and prevent fins from contacting each other and affecting heat exchange effect.

[0006] Preferably, the fin body is further provided with a positioning hole, and a positioning rod is inserted into the positioning hole; used for positioning in the width direction when multiple sets of fins are arranged.

[0007] Preferably, a flat tube groove is provided near the flat tube insertion hole of the fin body to guide the flat tube to be inserted and fixed in the flat tube insertion hole.

[0008] Preferably, the shape and size of the flat tube groove match the cross-section of the flat tube.

[0009] Preferably, a flange structure is provided on the periphery of one end of the positioning hole to facilitate the insertion of the positioning rod.

[0010] Preferably, the surface of the fin body is provided with two regions with different wetting properties.

[0011] Preferably, the two regions with different wetting properties include a superhydrophilic surface and a large contact angle surface.

[0012] Preferably, the first spacing structure includes a flat tube groove disposed on the fin body. After unfolding, the flat tube groove is a trapezoidal body with a shorter upper bottom edge integrally connected to the fin body. The trapezoidal body is bent backward at 90 degrees twice to form an L-shaped spacing structure two and a spacing structure three.

[0013] Preferably, the fin body is provided with a drainage structure, the drainage structure extends along the length direction of the fin body, and the edge of the fin body is provided with a flange structure.

[0014] Preferably, the fin body is provided with a louver structure, and the front ends of the flat tube groove of the fin body are provided with chamfer structures.

[0015] Beneficial effects

[0016] This invention provides a parallel-flow transverse insert fin with width positioning function. Compared with the prior art, it has the following advantages:

[0017] 1. In this utility model, the detachable connection of the flat tube is achieved through the setting of the spacing structure, the trapezoidal cross-section fin body with a 30° window angle and the positioning hole in the center. This not only facilitates disassembly and assembly and improves the flexibility of use, but also simplifies the production process, avoids complex bending processing, and thus reduces processing costs. The arc-shaped bend at the edge of the fin body and the cavity formed inside reduce airflow resistance and enhance structural strength, while improving heat exchange efficiency. In addition, the layered bend and spacing structure on the rear surface of the fin body effectively maintain the predetermined spacing between the fins, prevent the fins from contacting each other, ensure heat dissipation effect, and avoid heat exchange being affected by the fins being too close.

[0018] 2. In this utility model, by setting positioning holes, and through the flat tube grooves arranged along the length direction on the side of the window body and the positioning hole structure on the fin body, precise width direction positioning is achieved when multiple fins are arranged, ensuring that each horizontally inserted fin body is parallel to each other and remains in a flush state, thereby improving the overall heat exchange efficiency. At the same time, the precise matching design of the flat tube grooves allows the flat tubes to be firmly inserted and fixed, simplifying the installation process. The wavy structure of the lower edge of the capillary, combined with the different wetting performance areas of the superhydrophilic surface and the large contact angle surface, effectively reduces the formation of suspended water bridges, promotes the rapid discharge of water, reduces the adhesion of water on the fin surface, further improves the drainage performance and self-cleaning ability of the fins, and ultimately achieves a highly efficient, stable and easy-to-maintain heat dissipation effect.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides two technical solutions, specifically including the following embodiments:

[0029] Example 1:

[0030] A parallel-flow transverse insertion fin with width positioning function includes a fin body 1, which has a trapezoidal cross-section with a window angle of 30°. A flat tube insertion hole 2 is located in the center of the fin body 1 for inserting a flat tube 13. A spacing structure 3 is provided at the stacking interface of the fin body 1. The spacing structure 3 includes an arc-shaped bend 301, a cavity 302, and a layered bend 303. The arc-shaped bend 301 is located at the edge of the fin body 1 to reduce airflow resistance and enhance structural strength. The cavity 302 is formed inside the fin body 1 to reduce weight and improve heat exchange efficiency. The layered bend 303 is located on the rear surface of the fin body 1 to maintain a predetermined spacing between the fins and prevent the fins from contacting each other and affecting the heat exchange effect.

[0031] During operation, the trapezoidal cross-section fin body 1 with a 30° window angle and the flat tube insertion hole 2 in the center enable the detachable connection of the flat tube. This not only facilitates disassembly and assembly, improving the flexibility of use, but also simplifies the production process, avoids complex bending processing, and thus reduces processing costs. The arc-shaped bend 301 on the edge of the fin body 1 and the cavity 302 formed inside reduce airflow resistance and enhance structural strength, while improving heat exchange efficiency. In addition, the layered bend 303 and the spacing structures 3, 9, and 10 on the rear surface of the fin body 1 effectively maintain the predetermined spacing between the fins, prevent the fins from contacting each other, ensure heat dissipation, and avoid affecting heat exchange due to the fins being too close together.

[0032] Example 2:

[0033] Based on Embodiment 1, the fin body 1 is further provided with positioning holes 4 for positioning in the width direction when multiple sets of fins are arranged. A flat tube groove 6 is provided near the flat tube insertion hole 2 of the fin body 1 to guide the flat tube into and fix it in the flat tube insertion hole 2. The shape and size of the flat tube groove 6 match the cross-section of the flat tube. A capillary lower edge louver structure 5 is provided on the surface of the fin body 1. The louver structure 5 is a wave-shaped structure to reduce the formation of suspended water bridges. The surface of the fin body 1 is provided with two regions with different wetting properties: a superhydrophilic surface and a large contact angle surface. The contact angle of the superhydrophilic surface promotes rapid water expulsion, while the contact angle of the large contact angle surface reduces water adhesion on the fin surface. The body 1 is made of composite aluminum. Through the flat tube insertion grooves 2 arranged along the length direction on the side of its louver structure 5 and the positioning holes 4 on the fin body 1, precise width direction positioning is achieved when multiple fins are arranged. This ensures that each horizontal insertion fin body is parallel to each other and remains flush, thereby improving the overall heat exchange efficiency. At the same time, the precise matching design of the flat tube grooves 6 allows the flat tubes to be firmly inserted and fixed, simplifying the installation process. The wave-shaped structure of the louver structure 5, combined with the different wetting performance areas of the super-hydrophilic surface and the large contact angle surface, effectively reduces the formation of hanging water bridges, promotes the rapid discharge of water, reduces the adhesion of water on the fin surface, and further improves the drainage performance and self-cleaning ability of the fins. Ultimately, it achieves a highly efficient, stable and easy-to-maintain heat dissipation effect.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
