The fin structure of traditional heat exchangers is usually made of single-layer or simple multi-layer metal foil (such as aluminum foil, copper foil) plates. These heat exchange fins are fixed to heat exchange tubes (such as copper tubes) by welding or mechanical connection.

[0003] However, the existing designs have the following shortcomings: 1.

Easy to accumulate dust and difficult to clean; after the heat exchanger has been used for a long time, dust and dirt, especially fine particles and sticky substances, easily accumulate on the surface of the fins. This will significantly reduce the efficiency of airflow and the heat exchanger's heat exchange capacity, resulting in a decrease in thermal efficiency; traditional cleaning methods, such as manual wiping or blowing with compressed air, are not only complicated to operate but also difficult to clean thoroughly.

[0032] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] like Figures 1 to 9 As shown, an embodiment of the present invention provides a heat exchange fin structure, including: a fin body 10 and a guide fluid 20; the fin body 10 has mutually perpendicular length, width, and thickness directions; the fin body 10 has a plurality of mating holes 11, which penetrate the fin body 10 along the thickness direction and are used for heat exchange tubes 30 to pass through and connect to the heat exchange tubes 30; the plurality of mating holes 11 are arranged in rows along the length direction and in columns along the width direction; wherein, in each row and / or each column, at least a portion of the guide fluid 20 is located between two adjacent mating holes 11, the guide fluid 20 is disposed on the fin body 10 and protrudes from the fin body 10 along the thickness direction to form a flow channel 21, the flow channel 21 includes a plurality of openings 24, the openings 24 are located at the edge of the fin body 10, and the flow channel 21 communicates with the outside through the openings 24.

[0034] This invention effectively strengthens the fin body 10 by setting a guide fluid 20 on the fin body 10 and protruding it along the thickness direction. This significantly improves the strength and rigidity of the fin body 10, making it less prone to deformation or damage, thus enhancing the product's reliability and aesthetics. The opening 24 connects to the outside, allowing external air to circulate within the flow channel 21. This not only increases the turbulence of the airflow and improves the overall convective heat transfer effect, but also causes slight vibrations in the guide fluid 20 and the fin body 10. This vibration provides a degree of self-cleaning for the guide fluid 20 and the fin body 10, preventing the accumulation of dust and dirt after prolonged use. This reduces the labor intensity of manual cleaning and improves heat exchange efficiency. The heat exchange fin structure proposed in this invention significantly… This invention significantly enhances the product's durability and heat exchange efficiency. It not only effectively prevents deformation and damage during transportation and use, but also effectively cleans dust and dirt from the fin body 10 and the fluid guide 20 surface through the micro-vibrations generated by air impact, maintaining the heat exchanger's high-efficiency operation and extending its service life. The invention features a simple and low-cost structure, facilitating assembly and subsequent maintenance. It solves the problems of poor fin structure stability, easy dust accumulation and difficult cleaning, and low convective heat exchange efficiency in existing heat exchangers. When applied to heat exchangers, it significantly increases the heat exchange area per unit volume, achieving efficient energy utilization and rational distribution, and significantly improving the heat exchanger's energy efficiency. It provides a more efficient, reliable, and environmentally friendly heat exchange solution for industrial and civil applications, making it suitable for large-scale promotion and use.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the flow guide 20 includes a plurality of flow guide units 22; in at least a portion of the plurality of flow guide units 22, two adjacent flow guide units 22 are connected, and each flow guide unit 22 is arranged around the corresponding mating hole 11 in the circumferential direction so that the airflow in the flow channel 21 flows in the length direction or the width direction.

[0036] The above design allows the airflow in the flow channel 21 to flow along the length or width direction, increasing the airflow path and improving the heat exchange area, thereby enhancing the heat exchange efficiency of the heat exchanger. By optimizing the layout and shape of the flow guiding unit 22, the uniformity and turbulence of the airflow can be further improved, thereby enhancing the heat exchange performance.

[0037] like Figure 1 and Figure 2As shown, the two surfaces of the fin body 10 along the thickness direction are the first surface and the second surface, respectively; in at least a portion of the multiple flow guiding unit bodies 22, the flow guiding unit bodies 22 protrude from the first surface and the second surface, respectively.

[0038] The double-sided protruding design increases the structural strength of the fin body 10, while providing more airflow paths, allowing external air to enter the flow channel 21 from different directions, thus improving the heat exchanger's heat exchange efficiency and self-cleaning ability.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in at least a portion of the multiple flow guiding units 22, each flow guiding unit 22 surrounds the corresponding mating hole 11 in a triangular or polygonal shape, so that the flow channel 21 is arranged meanderingly along the length or width direction.

[0040] The flow channel 21 is meandering along the length or width direction, which increases the flow distance and turbulence of air in the flow channel 21, thereby improving the heat exchange efficiency. At the same time, this design can also help remove dust and dirt from the surface of the fin body 10 and the guide fluid 20 by increasing the turbulence of the airflow and thus through vibration, maintaining the cleanliness of the heat exchanger and extending its service life.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each flow guiding unit 22 surrounds the corresponding mating hole 11 in the form of an equilateral triangle, rhombus, or regular polygon; adjacent flow guiding units 22 are interconnected.

[0042] The aforementioned specific geometric design not only increases the complexity of airflow and the heat exchange area, but also forms a continuous flow channel 21 by connecting adjacent flow guide units 22, allowing airflow to flow smoothly in the fin structure and improving the convective heat transfer effect. At the same time, this design can also achieve self-cleaning of the fin surface through the vibration generated by the airflow, reducing dust accumulation and maintaining the efficient operation of the heat exchanger.

[0043] like Figure 5 As shown, in at least a portion of the multiple flow guiding units 22, each flow guiding unit 22 is arranged in a circular ring around the corresponding mating hole 11, so that the flow channel 21 of each flow guiding unit 22 is arranged around it; adjacent flow guiding units 22 are interconnected.

[0044] The two adjacent airflow guiding units 22 are interconnected. This design not only increases the airflow path and improves heat exchange efficiency, but also creates a surrounding flow channel 21, allowing the airflow to circulate within the fin structure. This increases the contact area between the air and the fins, further enhancing the heat exchange effect. The annular design also reduces airflow resistance, making the airflow smoother.

[0045] like Figure 8 As shown, the fin body 10 and the guide fluid 20 are integrally formed; or, the heat exchange fin structure includes two pressed plates 23, each pressed plate 23 having multiple mating holes 11 and through grooves arranged around the mating holes 11, the through grooves being recessed along the thickness direction; the two pressed plates 23 are pressed and fixed so that the multiple mating holes 11 and through grooves of the two pressed plates 23 are respectively connected, the two correspondingly connected through grooves form a flow channel 21, and the portion of the pressed plate 23 with through grooves forms the guide fluid 20.

[0046] This one-piece molding or two pressed plates design not only simplifies the manufacturing process and reduces production costs, but also improves the integrity and strength of the fin structure, making the heat exchanger less susceptible to damage during transportation and installation. At the same time, the flow channel 21 formed by the pressed plates increases the airflow path, improves heat exchange efficiency, and can also achieve self-cleaning of the fin surface through the vibration generated by the airflow, reducing dust accumulation and maintaining the efficient operation of the heat exchanger.

[0047] In one specific embodiment of this utility model, the two pressed plates 23 can be made of materials such as aluminum foil, copper foil, hydrophilic foil and light foil; the pressed plates 23 are formed by using a precision stamping process.

[0048] like Figure 1 and Figure 2 As shown, the two surfaces of the fin body 10 along the thickness direction are the first surface and the second surface, respectively; the portion of the fin body 10 with the mating hole 11 is a convex tube 12, and the convex tube 12 protrudes from at least one of the first surface and the second surface; the mating hole 11 located at the edge of each row and / or each column is an edge hole, and the flow channel 21 of the fluid guide 20 arranged around the edge hole has at least one opening 24, and the opening 24 communicates with the outside of the fin body 10.

[0049] This configuration increases the structural strength of the fin body 10 and provides more airflow paths, improving heat exchange efficiency. By setting the mating holes 11 located at the edges of each row and / or each column as edge holes, the flow channels 21 of the guide fluid 20 arranged around the edge holes have at least one opening 24. The opening 24 communicates with the outside of the fin body 10, which not only increases the airflow inlet but also optimizes the airflow path and improves the convective heat transfer effect through the setting of the opening 24. At the same time, multi-directional ventilation flow is also achieved through multiple openings 24, further improving the convective heat transfer efficiency.

[0050] Optionally, the guide fluid 20 also has multiple through holes that penetrate the guide fluid 20 along the thickness direction. The two ends of the through holes are respectively connected to the flow channel 21 and the outside of the fin body 10, so that external air enters the flow channel 21 along the thickness direction.

[0051] The above design further increases the airflow path and enhances the turbulence of the airflow, thereby improving the heat exchange effect. At the same time, the perforations can also help remove dust and dirt from the fin surface through the vibration generated by the airflow, maintaining the cleanliness of the heat exchanger and extending its service life.

[0052] like Figure 7 and Figure 9 As shown, this utility model also provides a heat exchanger, which includes the heat exchange fin structure described above; the heat exchanger also includes a plurality of heat exchange tubes 30, which are used to circulate heat exchange medium; the axial direction of the heat exchange tubes 30 is parallel to the thickness direction of the fin body 10, and the heat exchange tubes 30 pass through corresponding mating holes 11 and are limited to fit with the inner wall of the mating holes 11; wherein, a heat exchange group is formed by one fin body 10 and the guide fluid 20 located thereon, and there are multiple heat exchange groups, which are spaced apart along the axial direction of the heat exchange tubes 30.

[0053] The heat exchanger proposed in this invention not only increases the heat exchange area but also optimizes the airflow path, improving the convective heat exchange effect. At the same time, the airflow disturbance helps to remove dust and dirt from the fin surface, maintaining the cleanliness of the heat exchanger and extending its service life.

[0054] In one specific embodiment of this utility model, the heat exchange medium (such as water or steam) flows through the heat exchange tube 30, while external air contacts the fin body 10 through the flow channel 21 of the guide fluid 20 for heat exchange. The protruding design of the guide fluid 20 increases the structural stability of the fin body 10, preventing deformation or damage during transportation and installation. Simultaneously, the design of the flow channel 21 increases the airflow path and improves the turbulence of the airflow, thereby enhancing the heat exchange effect. The perforations further allow for micro-vibrations generated by airflow, helping to remove dust and dirt from the fin surface, maintaining the cleanliness of the heat exchanger and extending its service life. During operation, the optimized fin structure and flow channel design achieve efficient and stable heat exchange, while also possessing a self-cleaning function, reducing maintenance costs and improving overall operating efficiency.

[0055] In summary, this utility model provides a heat exchange fin structure and heat exchanger. By setting a guide fluid 20 on the fin body 10 and protruding it along the thickness direction, this utility model effectively strengthens the fin body 10, thereby improving its strength and rigidity, making it less prone to deformation or damage, and improving the reliability and aesthetics of the product. The opening 24 connects to the outside, allowing external air to circulate within the flow channel 21. This not only increases the turbulence of the airflow and improves the overall convective heat transfer effect, but also causes slight vibrations in the guide fluid 20 and the fin body 10 through the circulating external air. This vibration provides a certain degree of self-cleaning for the guide fluid 20 and the fin body 10, preventing the accumulation of dust and dirt after prolonged use, reducing manual cleaning labor intensity, and improving heat exchange efficiency. The newly proposed heat exchange fin structure significantly enhances the product's durability and heat exchange efficiency. It not only effectively prevents deformation and damage during transportation and use, but also effectively cleans dust and dirt from the fin body 10 and the fluid guide 20 surface through micro-vibrations generated by air impact, maintaining high-efficiency operation of the heat exchanger and extending its service life. This invention features a simple and low-cost structure, facilitating assembly and subsequent maintenance. It solves the problems of poor fin structure stability, easy dust accumulation and difficult cleaning, and low convective heat transfer efficiency in existing heat exchanger structures. When applied to heat exchangers, it significantly increases the heat exchange area per unit volume, achieving efficient energy utilization and rational distribution, and significantly improving the heat exchanger's energy efficiency. It provides a more efficient, reliable, and environmentally friendly heat exchange solution for industrial and civil applications, making it suitable for large-scale promotion and use.
