Description

Technical Field

[0001] This utility model relates to the field of fin technology, and in particular to a fin and a fin processing device. Background Technology

[0002] In the modern residential air conditioning manufacturing industry, the heat exchange efficiency of the indoor unit is one of the key factors affecting air conditioner performance. Currently, most residential air conditioner indoor units on the market use louvered fins to meet heat exchange requirements. Due to their louver-like structure, louvered fins effectively increase the contact area between air and the fins, thereby improving heat exchange performance. However, this design also brings a series of problems. First, the compressive strength of louvered fins is relatively low. During the manufacturing process, especially during handling and turnover, this design is prone to fin collapse, the so-called "fin collapse" problem. Fin collapse not only affects the appearance quality of the product but may also affect the performance of the air conditioner. Furthermore, due to the insufficient strength of the fins, additional protective measures are required in the existing production process, which undoubtedly increases production costs and complexity.

[0003] Secondly, due to insufficient fin strength, manual handling during placement and removal requires extreme care, directly impacting production efficiency. This issue is particularly pronounced in a manufacturing environment that prioritizes high efficiency and low costs. Furthermore, the issue of fins tipping over also leads to increased after-sales complaints. Consumers have stringent requirements for the appearance and performance of air conditioners, and this fin tipping problem often becomes a focal point of complaints, affecting brand image and customer satisfaction. Finally, due to the limitations of fin strength, the evaporator cannot be moved using robotic arms, restricting the application of automated production processes and increasing labor costs and production time.

[0004] Therefore, it is necessary to improve the existing windowed fins to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a fin that can effectively improve the strength of the fin by setting reinforcing ribs on the edge of the fin body, reduce the occurrence of fin collapse during fin turnover, and help improve the production efficiency of fins.

[0006] A fin includes a fin body, wherein the edge of the fin body is provided with reinforcing ribs, and the reinforcing ribs protrude from the surface of the fin body.

[0007] In actual production, the fin body can be made of aluminum foil. The aluminum foil is fed into a mold and passes through a louver step. At this point, a new type of louver punch uses a punching and forming principle to create reinforcing ribs in the aluminum foil during the stamping process. These reinforcing ribs are evenly distributed on both sides of the fin, further enhancing its overall strength. Furthermore, the number of reinforcing fin molds can be customized according to actual needs, enabling the stamping of multiple holes at once, thus improving production efficiency. When the fins are stacked to form an evaporator, the presence of the reinforcing ribs significantly improves the strength of the top and bottom surfaces of the evaporator, effectively reducing the occurrence of fin collapse. The reinforcing rib design not only enhances the strength of the fins but also makes them less prone to fin collapse and other appearance defects during transport, significantly improving the product's appearance quality.

[0008] In a preferred embodiment of this invention, the minimum distance between the reinforcing rib and the edge of the fin body is 0.5mm-0.7mm.

[0009] In a preferred embodiment of this invention, the cross-section of the reinforcing rib is circular, polygonal, or arc-shaped.

[0010] In this embodiment, the reinforcing ribs are located at the edge of the fin body, with a minimum distance of 0.5mm-0.7mm from the edge. This design ensures the effectiveness of the reinforcing ribs while preventing material breakage or deformation due to excessive proximity to the edge. The cross-section of the reinforcing ribs can be circular, polygonal, or arc-shaped. The choice of these shapes can be adjusted according to actual application requirements and manufacturing processes to achieve optimal reinforcement and aesthetics.

[0011] In a preferred embodiment of this invention, the reinforcing ribs are provided on both opposite sides of the fin body, and on any side of the fin body, there is at least one reinforcing rib.

[0012] In a preferred embodiment of this invention, a gap is provided between the two reinforcing ribs, and the minimum distance between the two reinforcing ribs is greater than 0.8 mm.

[0013] In this embodiment, a specific method for providing reinforcing ribs on a fin is provided, specifically: reinforcing ribs are provided on both opposite sides of the fin body, and on any side of the fin body, there is at least one reinforcing rib. This design ensures that the fin receives additional strength support in multiple directions.

[0014] The cross-section of the reinforcing rib can be circular, polygonal, or arc-shaped, and its minimum distance from the edge of the fin body is 0.5mm-0.7mm. This design ensures the stability of the reinforcing rib while avoiding material problems caused by being too close to the edge. A gap is provided between two opposing reinforcing ribs, with a minimum distance between them greater than 0.8mm. This gap design ensures sufficient space for normal heat exchange and mechanical deformation between the reinforcing ribs, preventing performance degradation or material damage caused by excessively dense reinforcing ribs.

[0015] The reinforcing ribs significantly enhance the overall structural strength of the fins, improving their resistance to deformation and damage.

[0016] In a preferred embodiment of this invention, the height of the reinforcing rib protruding from the surface of the fin body is 0.3mm-0.5mm.

[0017] In a preferred embodiment of this invention, the fin body is provided with a plurality of heat dissipation holes, and the axis of the heat dissipation holes is arranged along the length direction of the fin body.

[0018] The heat dissipation holes are formed on the fin body, and these holes are designed to further improve the heat dissipation efficiency of the fins. The axis of the heat dissipation holes is set along the length of the fin body. This layout helps to optimize the flow path of air or fluid, thereby removing heat more effectively.

[0019] The second objective of this invention is to provide a fin processing device for processing fins as described above.

[0020] In a preferred embodiment of this utility model, a die and a punch are included. The die has a first machining surface, and the punch has a second machining surface, which is disposed opposite to the first machining surface.

[0021] It also includes a driving device, wherein the punch is disposed at the output end of the driving device, and the driving device drives the punch to move closer to or away from the die;

[0022] The punch is also provided with rib forming protrusions, which protrude from the second processing surface.

[0023] In a preferred embodiment of this invention, a traction device is further included. The traction device is disposed on one side of the concave mold and the convex mold. The traction device includes a traction body and a clamping head. The clamping head is movably disposed on the traction body and is used to clamp the fins.

[0024] The fin processing apparatus provided in this application, through the cooperation of a die, a punch, and a drive device, enables rapid, batch processing of fins, thereby improving production efficiency. The ribs on the punch form a raised design, ensuring the precise forming of the reinforcing ribs and improving the quality of the fins.

[0025] The movable design of the traction device's clamping head allows the processing unit to adapt to the processing needs of fin materials of different sizes and shapes. Furthermore, the traction device enables continuous fin processing by moving the fins through the clamping head, thereby improving fin processing efficiency.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model provides a fin comprising a fin body, wherein reinforcing ribs are provided along the edge of the fin body, and the reinforcing ribs protrude from the surface of the fin body. By providing reinforcing ribs along the edge of the fin body, this fin significantly improves its strength, reduces the need for protective measures during fin production, and thus improves production efficiency. The reinforcing rib design not only enhances the strength of the fin but also makes it less prone to appearance defects such as fin tipping during transport, significantly improving the product's appearance quality.

[0028] This application also provides a fin processing apparatus for producing the above-mentioned fins. The processing apparatus can process fins with reinforcing ribs by stamping with a mold to ensure the strength of the fins. The fins with high strength can reduce the occurrence of fin collapse problems during fin turnover, which helps to improve the production efficiency of fins. Attached Figure Description

[0036] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0037] Existing louvered fins, due to their louver-like structure, effectively increase the contact area between air and the fins, thereby improving heat exchange performance. However, this design also brings a series of problems. First, the compressive strength of louvered fins is relatively low. During the manufacturing process, especially during handling and turnover, this design is prone to fin collapse, the so-called "fin collapse" problem. Fin collapse not only affects the appearance quality of the product but may also affect the performance of the air conditioner. In addition, due to the insufficient strength of the fins, additional protective measures are required in the existing production process, which undoubtedly increases production costs and complexity.

[0038] Secondly, due to insufficient fin strength, manual handling during placement and removal requires extreme care, directly impacting production efficiency. This issue is particularly pronounced in a manufacturing environment that prioritizes high efficiency and low costs. Furthermore, the issue of fins tipping over also leads to increased after-sales complaints. Consumers have stringent requirements for the appearance and performance of air conditioners, and this fin tipping problem often becomes a focal point of complaints, affecting brand image and customer satisfaction. Finally, due to the limitations of fin strength, the evaporator cannot be moved using robotic arms, restricting the application of automated production processes and increasing labor costs and production time.

[0039] Based on this, this application provides a fin.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment provides a fin, including a fin body 1, with reinforcing ribs 12 provided on the edge of the fin body 1, and the reinforcing ribs 12 protruding from the surface of the fin body 1.

[0042] In actual production, the fin body 1 can be made of aluminum foil. The aluminum foil is fed into the mold and passes through the louver step. At this time, the new type of louver punch uses the principle of concave-convex stamping to form reinforcing ribs 12 on the aluminum foil during the stamping process. These reinforcing ribs 12 are evenly distributed on both sides of the fin, thereby further enhancing the overall strength of the fin. In addition, according to actual needs, the number of reinforcing fin molds can be customized to achieve the function of stamping multiple holes at once, thereby improving production efficiency. When the fins are stacked to form an evaporator, the strength of the upper and lower surfaces of the evaporator is also significantly improved due to the presence of the reinforcing ribs 12, which effectively reduces the occurrence of fin collapse problems. The design of the reinforcing ribs 12 not only enhances the strength of the fins, but also makes the fins less prone to appearance defects such as fin collapse during transportation, significantly improving the appearance quality of the product.

[0043] Specifically, the minimum distance between the reinforcing rib 12 and the edge of the fin body 1 is 0.5mm-0.7mm.

[0044] In this embodiment, a specific structure for the reinforcing rib 12 is also provided. Specifically, the cross-section of the reinforcing rib 12 is circular, polygonal, or arc-shaped. Furthermore, in this embodiment, the protrusion height of the reinforcing rib 12 from the surface of the fin body 1 is 0.3mm-0.5mm.

[0045] In this embodiment, the reinforcing rib 12 is disposed at the edge of the fin body 1, and the minimum distance from the edge of the fin body 1 is 0.5mm-0.7mm. This design ensures the effectiveness of the reinforcing rib 12 while avoiding material cracking or deformation caused by being too close to the edge. The cross-section of the reinforcing rib 12 can be circular, polygonal, or arc-shaped. The choice of these shapes can be adjusted according to actual application requirements and manufacturing processes to achieve the best reinforcement effect and aesthetics.

[0047] This embodiment provides a specific implementation of the reinforcing rib 12.

[0048] like Figure 1 As shown, in this embodiment, the reinforcing ribs 12 are provided on both opposite sides of the fin body 1, and the number of reinforcing ribs 12 on any side of the fin body 1 is at least one.

[0049] In this embodiment, a gap is provided between the two reinforcing ribs 12, and the minimum distance between the two reinforcing ribs 12 is greater than 0.8 mm.

[0050] In this embodiment, a specific arrangement of the reinforcing ribs 12 on the fin is provided, specifically: reinforcing ribs 12 are provided on both opposite sides of the fin body 1, and the number of reinforcing ribs 12 on any side of the fin body 1 is at least one. This design ensures that the fin can obtain additional strength support in multiple directions.

[0051] The cross-section of the reinforcing rib 12 can be circular, polygonal, or arc-shaped, and its minimum distance from the edge of the fin body 1 is 0.5mm-0.7mm. This design ensures the stability of the reinforcing rib 12 while avoiding material problems caused by being too close to the edge. A gap is provided between two relative reinforcing ribs 12, and the minimum distance between two relative reinforcing ribs 12 is greater than 0.8mm. This gap design ensures that the material between the reinforcing ribs 12 has sufficient space for normal heat exchange and mechanical deformation, avoiding performance degradation or material damage caused by excessively dense reinforcing ribs 12.

[0052] The 12 reinforcing ribs significantly enhance the overall structural strength of the fins, improving their resistance to deformation and damage.

[0053] In this embodiment, the reinforcing rib 12 protrudes from the surface of the fin body 1 at a height of 0.3mm-0.5mm.

[0054] In this embodiment, a plurality of heat dissipation holes 11 are provided on the fin body 1, and the axis of the heat dissipation holes 11 is arranged along the length direction of the fin body 1.

[0055] Heat dissipation holes 11 are formed on the fin body 1. These heat dissipation holes 11 are designed to further improve the heat dissipation efficiency of the fins. The axis of the heat dissipation holes 11 is set along the length direction of the fin body 1. This layout helps to optimize the flow path of air or fluid, thereby removing heat more effectively.

[0056] Example 3

[0057] This embodiment provides a limited number of reinforcing ribs 12.

[0058] like Figure 1 As shown, in this embodiment, the reinforcing ribs 12 are provided on both opposite sides of the fin body 1, and the number of reinforcing ribs 12 on any side of the fin body 1 is 2-3.

[0059] Similarly, a gap is provided between the two reinforcing ribs 12, and the minimum distance between the two reinforcing ribs 12 is greater than 0.8 mm.

[0060] In this embodiment, a specific arrangement of the reinforcing ribs 12 on the fin is provided, specifically: reinforcing ribs 12 are provided on both opposite sides of the fin body 1, and the number of reinforcing ribs 12 on any side of the fin body 1 is at least one. This design ensures that the fin can obtain additional strength support in multiple directions.

[0061] The cross-section of the reinforcing rib 12 can be circular, polygonal, or arc-shaped, and its minimum distance from the edge of the fin body 1 is 0.5mm-0.7mm.

[0062] Example 4

[0063] like Figures 2-4 As shown, this embodiment provides a fin processing apparatus for processing fins as described above.

[0064] In this embodiment, a concave die 3 and a convex die 2 are included. The concave die 3 is provided with a first processing surface 31, and the convex die 2 is provided with a second processing surface 21. The second processing surface 21 is disposed opposite to the first processing surface 31.

[0065] It also includes a driving device, wherein the punch 2 is disposed at the output end of the driving device, and the driving device drives the punch 2 to move closer to or away from the die 3;

[0066] The punch 2 is also provided with a rib forming protrusion 22, which protrudes from the second processing surface 21. The punch 2 is installed at the output end of the drive device. Through the driving force of the drive device, the punch 2 can move closer to or further away from the die 3 to realize the stamping action.

[0067] In this embodiment, a traction device is also included. The traction device is disposed on one side of the concave mold 3 and the convex mold 2. The traction device includes a traction body and a clamping head. The clamping head is movably disposed on the traction body and is used to clamp the fins.

[0068] It is set on one side of the concave die 3 and the convex die 2, and is used to pull and position the fin material during processing.

[0069] The traction device includes a traction body and a clamping head. The clamping head is movably mounted on the traction body and can be flexibly adjusted to clamp fin materials of different sizes.

[0070] The fin processing apparatus provided in this application, through the cooperation of the die 3, the punch 2, and the driving device, enables rapid and batch processing of fins, thereby improving production efficiency. The ribs on the punch 2 form protrusions 22, which ensures the precise forming of the reinforcing ribs 12 and improves the quality of the fins.

[0071] The movable design of the traction device's clamping head allows the processing unit to adapt to the processing needs of fin materials of different sizes and shapes. Furthermore, the traction device enables continuous fin processing by moving the fins through the clamping head, thereby improving fin processing efficiency.

[0072] The fin processing device provided in this embodiment processes fins in the following way:

[0073] Aluminum foil material or other suitable fin material is placed on the first processing surface 31 of the die 3 and fixed by the clamping head of the traction device.

[0074] The drive unit is activated, pushing the punch 2 closer to the die 3. The ribs on the punch 2 form protrusions 22 that cooperate with the first processing surface 31 of the die 3 to stamp the aluminum foil material, forming the shape of fins and reinforcing ribs 12.

[0075] After stamping is completed, the drive device drives the punch 2 away from the die 3, and at the same time the traction device releases the clamping head and takes out the processed fins.

[0076] Specifically, the traction device of this application may include a linear guide rail and a clamping head. The clamping head is pneumatically opened and closed for clamping. The clamping head is fixed on the slider of the linear guide rail. The linear guide rail drives the traction head to move, thereby realizing the traction of the fins.
