Description

Technical Field

[0001] This utility model relates to the technical field of all-aluminum structure radiators, specifically to a side plate structure for insert-type riveting of radiators. Background Technology

[0002] As the automotive industry continues to reduce the space available for radiator installation, all-aluminum radiators have become widely used due to their advantages of lightweight design and high heat dissipation efficiency. In the core assembly process of all-aluminum radiators, the fixing of the insert-type side plates is one of the key steps, and its fixing efficiency directly affects the overall production pace of the radiator.

[0003] In existing technologies, heatsink insert-type side panels are typically fixed to the motherboard using argon arc welding after the core assembly. This method has two major problems: first, it is inefficient, with each side panel taking approximately 40 seconds to fix, which cannot meet the needs of large-scale mass production; second, it is costly, as the purchase, maintenance, and welding consumables of argon arc welding equipment all increase production costs, and the need for specialized operators further increases labor costs. Furthermore, the welding process may generate localized high temperatures, causing micro-deformation of the aluminum material, affecting the assembly accuracy of the heatsink core and making it difficult to consistently meet customer requirements for product size and structural stability. Therefore, there is an urgent need to design a new side panel structure that can achieve efficient assembly and low cost while ensuring fixed reliability and assembly accuracy. Thus, a heatsink insert-type riveted side panel structure needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a side plate structure for insert-type riveting of radiators, which solves the problems of low efficiency, high cost and easy deformation caused by the reliance on argon arc welding for spot welding of existing insert-type side plates.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side plate structure for insert-type riveting of a heat sink, comprising a heat sink main board and an insert-type side plate that cooperates with the main board. The side plate has a riveting protrusion on the side facing the main board, the riveting protrusion being arranged along the length direction of the side plate. The main board has a plurality of positioning holes corresponding to the riveting protrusion, the diameter of the positioning holes being adapted to the diameter of the riveting protrusion, and the height of the riveting protrusion being greater than the thickness of the main board.

[0006] A further improvement of this utility model is that: the end of the rivet protrusion away from the side plate is provided with a guide chamfer, and the rivet protrusion can improve the anti-torsion performance of the main board after riveting, and adapt to the fixing requirements under different working conditions.

[0007] A further improvement of this utility model is that: the two ends of the side plate are respectively provided with limiting flanges that are adapted to the edge of the heat sink core. The limiting flanges are set perpendicular to the side plate, and the limiting flanges can accurately position the assembly position of the side plate and the core.

[0008] A further improvement of this utility model is that: the inner side of the limiting fold is provided with anti-slip texture, which can increase the friction between the limiting fold and the core.

[0009] A further improvement of this utility model is that the side plate and the rivet protrusion are integrally stamped and formed, which eliminates the need for additional splicing processes and reduces processing costs.

[0010] A further improvement of this utility model is that the positioning hole edge of the motherboard is provided with a rounded transition, which can avoid stress concentration at the edge of the positioning hole.

[0011] A further improvement of this utility model is that: the motherboard is provided with a reinforcing boss at the position corresponding to the positioning hole, and the reinforcing boss is integrally formed with the motherboard. The reinforcing boss can enhance the structural strength of the area around the positioning hole and improve the connection stability between the motherboard and the side plate.

[0012] 1. Dual optimization of efficiency and cost: The TIG welding spot welding process is eliminated, and the riveting and fixing are combined with normal assembly, with no extra production time. Compared with the traditional processing time of 40 seconds per piece, the efficiency is improved by more than 90%. There is no need to purchase TIG welding equipment and welding consumables, nor is there a need for professional welding personnel, which reduces costs in terms of equipment, consumables and manpower.

[0013] 2. Improved structural stability and precision: The integrated stamping process, combined with the distribution of riveting protrusions and the reinforced boss design of the motherboard, ensures that the fixing strength meets the customer's requirements for the structural stability of the heat sink. The design of limiting folds, guide chamfers and rounded transitions reduces the alignment and adjustment steps during assembly, reduces the difficulty of operation, and avoids material deformation caused by high welding temperatures.

[0014] 3. High adaptability and practicality: The entire structure and assembly method do not require complex equipment and can be directly modified and upgraded on existing radiator production lines without large-scale tooling changes, making it easy for enterprises to quickly promote and apply.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] This embodiment provides a side plate structure for insert-type riveting of a heat sink, including a heat sink main board 1 and an insert-type side plate 2 that cooperates with the main board 1. The side plate 2 has a riveting protrusion 3 on the side facing the main board 1. The riveting protrusion 3 is arranged along the length direction of the side plate 2. The main board 1 has a plurality of positioning holes 4 corresponding to the riveting protrusion 3. The diameter of the positioning holes 4 is adapted to the diameter of the riveting protrusion 3, and the height of the riveting protrusion 3 is greater than the thickness of the main board 1. The end of the riveting protrusion 3 away from the side plate 2 has a guide chamfer 5. The riveting protrusion 3 can improve the torsional resistance of the main board 1 after riveting and adapt to the fixing requirements under different working conditions. The guide chamfer 5 can guide the riveting protrusion 3 to quickly insert into the positioning holes 4, reduce the alignment time during assembly, and at the same time avoid burrs on the edge of the positioning holes 4 due to hard insertion.

[0019] The side plate 2 has limiting flanges 6 at both ends that are adapted to the edge of the radiator core. The limiting flanges 6 are perpendicular to the side plate 2 and can accurately position the side plate 2 and the core during assembly, preventing the side plate 2 from shifting during assembly. The inner side of the limiting flanges 6 has anti-slip textures 7, which can increase the friction between the limiting flanges 6 and the core, preventing the core from shifting in subsequent processes and ensuring the overall assembly accuracy of the radiator core. The side plate 2 and the rivet protrusion 3 are integrally stamped structures. The integral stamping process eliminates the need for additional splicing processes, which not only ensures the connection strength between the rivet protrusion 3 and the side plate 2, but also simplifies the early processing of the side plate 2 and reduces processing costs.

[0020] The positioning hole 4 of the motherboard 1 has an arc transition 8 at its edge. The arc transition 8 can avoid stress concentration at the edge of the positioning hole 4 and prevent the motherboard 1 from cracking during the riveting process. The motherboard 1 has a reinforcing boss 9 at the position corresponding to the positioning hole 4. The reinforcing boss 9 is integrally formed with the motherboard 1. The reinforcing boss 9 can enhance the structural strength of the area around the positioning hole 4, improve the connection stability between the motherboard 1 and the side plate 2, and extend the service life of the heat sink.

[0021] 1. Pre-processing inspection: Check whether the rivet protrusions 3, guide chamfers 5 and limit folds 6 of the side plate are intact, and whether the positioning holes 4, arc transitions 8 and reinforcing bosses 9 of the main plate 1 meet the dimensional requirements, to ensure that there are no burrs, deformations and other defects, so as to avoid affecting subsequent assembly.

[0022] 2. Preliminary positioning and assembly: Place the heat sink core on the assembly fixture. According to the edge contour of the core, align the limiting fold 6 of the side plate 2 with the edge of the core to complete the preliminary positioning of the side plate 2. Then adjust the position of the main board 1 so that the positioning hole 4 of the main board 1 is aligned with the rivet protrusion 3 of the side plate 2. Guide the rivet protrusion 3 into the positioning hole 4 through the guide chamfer 5 until the side plate 2 and the main board 1 are in contact. At this time, the end of the rivet protrusion 3 away from the side plate 2 protrudes from the reinforcing boss 9 of the main board 1.

[0023] 3. Riveting Fixing: Start the radiator assembly machine, align the riveting mold of the assembly machine with the riveting protrusion 3 extending from the reinforcing boss 9, set the riveting pressure to 0.5MPa and the holding time to 2-3 seconds, and squeeze the riveting protrusion 3 through the riveting mold to cause plastic deformation at the end of the riveting protrusion 3, forming a pressing part with a diameter larger than the hole diameter of the positioning hole 4, pressing the surface of the reinforcing boss 9 of the main board 1, and completing the fixing of the side plate 2 and the main board 1.

[0024] 4. Process Integration and Inspection: The riveting and fixing process is carried out simultaneously with the assembly process of the heat sink core tube and heat sink strip, without taking up extra production time. After assembly, the connection strength between the side plate and the main plate is sampled and tested by tensile testing equipment to ensure that the tensile force value is not less than 150N. At the same time, the overall dimensional deviation of the heat sink core is checked to ensure that it meets customer requirements.

[0025] The above are merely preferred embodiments of this utility model, but do not limit the patent scope of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features.
