Description

Technical Field

[0001] This utility model relates to the field of automotive heat exchanger technology, and in particular to an improved radiator main plate. Background Technology

[0002] In the manufacturing of automotive radiator fins, traditional structures typically employ a right-angled cross-section design. The right-angle transitions at the intersections easily lead to stress concentration, causing fatigue cracks under long-term vibration loads. With the development of lightweight requirements in new energy vehicles, the thickness of the fins has been reduced. Traditional designs, due to insufficient structural strength, make it difficult to meet reliable sealing requirements for the height of the welding contact surface. At the same time, the lack of effective positioning benchmarks during radiator pipe assembly easily leads to installation deviations.

[0003] Existing improvement solutions mostly enhance performance by adding reinforcing components or complex processes, which not only significantly increases material costs but also makes production processes more cumbersome. How to achieve synergistic improvements in stress optimization distribution, assembly precision control, and process simplification under thin-walled conditions has become a pressing technical challenge for the industry. To address this, we propose an improved radiator main plate. Utility Model Content

[0004] To overcome the shortcomings of existing radiator main plates, such as stress concentration, insufficient assembly precision, and the contradiction between lightweight and strength, this utility model discloses an improved radiator main plate. Through structural optimization, it achieves a synergistic improvement in stress dispersion, rigidity enhancement, and precision assembly, while reducing the complexity of the stamping process.

[0005] The technical solution of this utility model is:

[0006] An improved heat sink main plate includes a main plate body and a solid support area in the middle. The solid support area has a cross-shaped partition structure with a 2.4mm radius rounded corner transition at the intersection, dividing the middle part of the main plate body into symmetrical areas. Each area has parallel waist-shaped holes for fixing heat pipes. The edges of the solid support area are independently stamped with an array of transverse convex reinforcing ribs as a reinforcement structure. The rounded corner transition of the cross partition and the staggered layout of the edge convex reinforcing ribs form a composite reinforcement structure to maintain the thickness of the main plate body at 1.5mm.

[0007] In a further technical solution, the radius of the rounded transition at the intersection of the cross-shaped partition structure is 2.4mm, the division angle of the four symmetrical regions is orthogonally distributed at 90°, and the central axis of the waist-shaped hole for fixing the heat dissipation pipe within the symmetrical region is parallel to the boundary of the cross-shaped partition structure.

[0008] In a further technical solution, the width of the waist-shaped hole for fixing the heat sink is 1.6 mm, the length is 14.5 mm, the radius of the semicircle at the end is 0.8 mm, the center distance between adjacent holes is 6.5 mm, and the ratio of the total length of the waist-shaped hole for fixing the heat sink to the width of the symmetrical area is 1:1.2.

[0009] In a further technical solution, the single structure width of the convex reinforcing rib array is 4.9mm, the length of the convex reinforcing rib is 8mm, the semi-circular radius of the end of the convex reinforcing rib is 1.6mm, the center distance between adjacent convex reinforcing ribs is 6.5mm, the stamping depth is 2.5mm, and the arrangement direction of the convex reinforcing rib array forms a 90° angle with the cross partition axis.

[0010] In a further technical solution, the thickness of the main body is 1.5mm, and the thickness consistency error between the solid support area and the edge convex reinforcing rib area is less than or equal to 0.1mm.

[0011] The beneficial effects of this utility model are:

[0012] Compared with existing technologies, this structure can maintain its structural strength while reducing the thickness of the main sheet, and can meet the reliable sealing requirements of the welding contact surface height. At the same time, it has a positioning reference during the heat dissipation pipe assembly process, which enables fast and efficient assembly. It also has high installation accuracy, and the manufacturing process of this structure is simple, the material cost is low, and it can be used for mass production, reducing the cost of production equipment and personnel. It achieves a synergistic improvement in stress optimization distribution, assembly accuracy control and process simplification under thin-walled conditions. Attached Figure Description

[0020] Example:

[0021] like Figures 1-4 As shown, an improved heat sink main plate includes a solid support area in the middle of the main plate body 1, and the middle of the main plate body 1 is provided with a plurality of evenly spaced heat sink tube fixing waist-shaped holes 2.

[0022] The solid support area has a cross-shaped partition structure 4, with a 2.4mm radius rounded corner transition at the intersection, dividing the middle of the sheet body 1 into orthogonally symmetrical areas. In each area, heat dissipation pipe fixing waist-shaped holes 2 are arranged in parallel. The solid support area edge is stamped with a transverse convex reinforcing rib array 3 as a reinforcing structure. Through the stress dispersion design of the cross-shaped partition structure 4 and the staggered layout of the convex reinforcing ribs, a composite reinforced structure is formed, which achieves the synergistic effect of stress dispersion and edge rigidity improvement while maintaining the 1.5mm thickness of the main sheet body.

[0023] Furthermore, the radius of the rounded corner at the intersection of the cross-shaped partition structure 4 is 2.4mm, the four symmetrical regions are orthogonally distributed at 90°, and the central axis of the heat dissipation pipe fixing waist-shaped hole 2 is parallel to the boundary of the cross partition.

[0024] Furthermore, the width of the waist-shaped hole 2 for fixing the heat pipe is 1.6mm, the length is 14.5mm, the radius of the semicircle at the end is 0.8mm, the center distance between adjacent holes is 6.5mm, and the ratio of the total length of the waist-shaped hole to the width of the symmetrical area is 1:1.2.

[0025] Furthermore, the width of each individual unit of the transverse convex reinforcing rib 3 array is 4.9mm, the length of the convex reinforcing rib 3 is 8mm, the radius of the semicircle at the end is 1.6mm, the center distance between adjacent convex reinforcing ribs 3 is 6.5mm, the stamping depth is 2.5mm, and the arrangement direction of the convex reinforcing ribs 3 forms a 90° angle with the cross section axis.

[0026] Furthermore, the thickness of the main body 1 is 1.5mm, and the thickness of the solid support area and the convex reinforcing rib area 3 are the same.

[0027] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
