Description

Technical Field

[0001] This application relates to the field of radiators, and more particularly to a tooling and its usage method. Background Technology

[0002] Server heatsinks consist of a base and multiple heatsink fins welded to it. The heatsink fins can be up to 64 mm high, but only 0.3 mm thick. Welding the heatsink fins to the base requires significant pressure to ensure a strong weld. However, the thin and tall heatsink fins have poor mechanical stability, making them prone to bending and deformation. This deformation not only affects the heatsink's appearance but also disrupts the internal airflow structure, obstructing airflow and significantly reducing heat dissipation efficiency, ultimately impacting server performance, reliability, and lifespan. Summary of the Invention

[0003] To address the problems in the prior art, embodiments of this application provide a tooling.

[0004] In addition, this application also provides a method for using the tooling.

[0005] A tooling for supporting a plurality of workpieces to be processed spaced apart, the tooling including a base and a plurality of support members, the plurality of support members being disposed on one side of the base, and a limiting space being defined between each pair of adjacent support members, the limiting space being configured to accommodate the workpieces to be processed.

[0006] In some possible implementations, the base includes a first surface, a second surface, and a plurality of first connecting surfaces, the first surface and the second surface being spaced apart, the first connecting surfaces being connected between the first surface and the second surface, and a plurality of support members being arranged side by side on the first surface, with each pair of adjacent support members being arranged in parallel and spaced apart.

[0007] In some possible implementations, the base has a length direction and a thickness direction, a plurality of the support members are arranged side by side along the length direction, and a plurality of the support members extend away from the base along the thickness direction.

[0008] In some possible implementations, the forward projection of the plurality of the supports is located within the base along the thickness direction.

[0009] In some possible implementations, each of the support members has a thickness of 0.1 to 0.5 mm and a height greater than 3 mm.

[0010] In some possible implementations, each of the support members includes a third surface, a fourth surface, and a plurality of second connecting surfaces, the third surface and the fourth surface being disposed at a distance from each other, the second connecting surfaces being connected between the third surface and the fourth surface, and the second connecting surfaces including arc surfaces.

[0011] In some possible implementations, the base is made of aluminum alloy or stainless steel, and the support is made of polyoxymethylene.

[0012] A method of using the tooling as described above includes the steps of: inserting a plurality of workpieces to be processed into the tooling, each workpiece being defined in a limiting space between two adjacent supports; welding the workpieces to be processed and a base; and removing the tooling.

[0013] In some possible implementations, the gap width between any two adjacent workpieces is M, and correspondingly, the distance between any two adjacent supports is D, wherein the following relationship is satisfied: 0.5mm <D<0.75M。

[0014] In some possible implementations, the step of “welding the workpiece and the base” may include: positioning the base using a welding fixture.

[0015] The fixture provided in this application, through a combination design of a base and multiple supporting components, defines a limiting space between the supporting components to accommodate spaced heat dissipation fins. This structure provides independent support and limitation for the fins during welding, distributing welding pressure and preventing bending deformation of the fins due to poor mechanical stability, thus ensuring their neat arrangement. Therefore, the fixture effectively protects the internal airflow structure of the radiator, ensuring smooth airflow and improving heat dissipation efficiency, thereby solving the problem of reduced performance, reliability, and lifespan of radiators caused by fin deformation in the prior art.

[0023] Please see Figure 1 and Figure 3 One embodiment of this application provides a tooling 100, which is applied to support the heat dissipation fins 201 of the heat sink 200 so that the heat dissipation fins 201 are welded to the heat dissipation base 202.

[0024] Please see Figure 1 and Figure 2, in this embodiment, the tooling 100 includes a base 10 and a plurality of comb-shaped support members 20. The plurality of support members 20 are provided on one side of the base 10. A limiting space 21 is defined between every two adjacent support members 20, and the limiting space 21 communicates with the external environment. The limiting space 21 is used to accommodate the workpiece to be processed. Among them, the plurality of support members 20 are fixedly connected to one side of the base 10. In other embodiments, the plurality of support members 20 can be movably provided on one side or multiple sides of the base 10, so as to define limiting spaces 21 with different shapes and sizes, thereby adapting to different workpieces to be processed.

[0025] When specifically using the tooling 100, first align the plurality of heat dissipation fins 201 with the heat dissipation base 202. A gap is formed between every two adjacent heat dissipation fins 201, and the width of this gap needs to be precisely controlled within a specific range. For example, the width of the gap between every two adjacent heat dissipation fins 201 is 5 - 8 mm. Then insert the plurality of support members 20 of the tooling 100 into the plurality of gaps respectively. At this time, the plurality of heat dissipation fins 201 are inserted into the plurality of limiting spaces 21 one by one. In this way, a stable fin arrangement structure is formed, thereby improving the stability during the process of welding the plurality of heat dissipation fins 201 to the heat dissipation base 202, and effectively reducing the bending risk of the heat dissipation fins 201.

[0026] In this embodiment, the width of the gap between every two adjacent heat dissipation fins 201 is M. Correspondingly, the distance between every two adjacent support members 20 is D. Among them, the following relationship is satisfied: 0.5mm < D < 0.75M. For example, when M is 5 mm, D can take values from 2.5 to 3.75 mm; when M is 8 mm, D can take values from 4 to 6 mm. In this way, it is ensured that the plurality of support members 20 can be inserted smoothly, and at the same time, close fitting is achieved, realizing effective and reliable lateral support.

[0027] In this embodiment, the base 10 is generally in the shape of a cuboid, and the base 10 has a length direction A, a width direction B, and a thickness direction C. Among them, any two of the length direction A, the width direction B, and the thickness direction C are perpendicular to each other. The base 10 includes a first surface 11, a second surface 12, and a plurality of first connection surfaces 13. Along the thickness direction C, the first surface 11 and the second surface 12 are spaced apart relatively. The plurality of first connection surfaces 13 are connected between the first surface 11 and the second surface 12. The plurality of support members 20 are arranged side by side on the first surface 11, and every two adjacent support members 20 are arranged in parallel at intervals.

[0028] In this embodiment, multiple support members 20 are arranged side by side along the length direction A, and extend away from the base 10 along the width direction B and the thickness direction C. This layout is beneficial for efficiently supporting and positioning the heat dissipation fins 201 without increasing the volume of the fixture 100 too much. Along the thickness direction C, the forward projection of the multiple support members 20 is located within the base 10. This design ensures the compactness and stability of the overall structure of the fixture 100 and avoids unnecessary shaking or displacement of the support members 20 during use.

[0029] In this embodiment, along the length direction A, the distance D between any two adjacent support members 20 is 5-8 mm to ensure that the heat dissipation fins 201 can be smoothly inserted between adjacent support members 20. The thickness T of each support member 20 is 0.1-0.5 mm, which provides sufficient support without excessively pressurizing the heat dissipation fins 201. Along the thickness direction C, the height H of each support member 20 is greater than 3 mm to completely cover the heat dissipation fins 201 during installation, providing comprehensive support.

[0030] In this embodiment, each support member 20 is generally plate-shaped, including a third surface 22, a fourth surface 23, and a plurality of second connecting surfaces 24. The third surface 22 and the fourth surface 23 are arranged at intervals relative to each other, and the second connecting surfaces 24 connect the third surface 22 and the fourth surface 23, and the second connecting surfaces 24 include arc surfaces. The arc surfaces designed in this way can better distribute pressure when in contact with the heat sink fins 201, reduce damage to the surface of the heat sink fins 201, and also facilitate smoother guidance of the support member 20 when inserting into the gap.

[0031] In this embodiment, the base 10 is made of high-strength aluminum alloy, which has advantages such as light weight, high strength, and good thermal conductivity. It can ensure the overall strength of the tooling 100 and also assist in heat dissipation to a certain extent. The support 20 is made of engineering plastic, such as polyoxymethylene (POM). This material has good wear resistance, self-lubrication, and a certain degree of elasticity. It can provide appropriate cushioning when in contact with the heat sink fins 201, further reducing the risk of damage to the heat sink fins 201. At the same time, its stable physical properties can also ensure the reliability of the support during the welding process.

[0032] Please see Figure 3 and Figure 4 An embodiment of this application also provides a method of using the tooling 100, including the following steps: S1: Preparation. For example, inspect fixture 100 and welding jig 300: ensure that fixture 100 and welding jig 300 are intact, dimensionally compatible, and free from damage or wear. Clean fixture 100 and the heat sink 200 to be welded: clean fixture 100, heat sink fins 201, and heat sink base 202 to remove dust, oil, and other impurities from the surfaces to ensure welding quality.

[0033] S2: Loading into the welding fixture 300. For example, loading the heat sink 200 to be welded into the welding fixture 300: Correctly place the heat sink 200 to be welded into the welding fixture 300, ensuring accurate alignment of the heat dissipation fins 201 and the heat dissipation base 202. Securing the heat sink 200: Using the fixing device of the welding fixture 300, securely fix the heat dissipation base 202 in the welding fixture 300 to prevent movement or tilting during the welding process.

[0034] S3: Install fixture 100. For example, install one fixture 100 on each side of the heat sink fin 201: Install the fixture 100 on each side of the heat sink fin 201, so that the support member 20 of the fixture 100 fits tightly against the side of the heat sink fin 201. That is, each heat sink fin 201 is defined in the limiting space 21 between two adjacent support members 20. Adjust position: Ensure that the comb teeth of the fixture 100 are accurately aligned with the heat sink fin 201, providing uniform lateral support and preventing the heat sink fin 201 from shifting or deforming during welding.

[0035] S4: Welding operation. For example, sending the radiator 200 to be welded into the oven for welding: The radiator 200, equipped with tooling 100 and welding fixture 300, is sent into the oven and welded according to the predetermined welding process parameters (such as temperature, time, pressure, etc.). Welding process monitoring: During the welding process, parameters such as temperature and pressure are monitored in real time to ensure stable and reliable welding quality.

[0036] S5: Cooling and Disassembly. For example, removing the radiator 200 from the oven: After welding, remove the radiator 200 from the oven and place it in a safe area to cool naturally, avoiding material stress changes due to a sudden drop in temperature. Removing the fixture 100: After the radiator 200 has cooled to a safe temperature, carefully remove the fixtures 100 on both sides to prevent damage to the heat dissipation fins 201. Removing the welding jig 300: Finally, remove the welded radiator 200 from the welding jig 300, completing the entire welding process.

[0037] S6: Quality Inspection. For example, visual inspection: Check whether the heat dissipation fins 201 are neatly arranged, without bending, deformation, or damage, ensuring the appearance quality meets requirements. Welding quality inspection: Inspect the welded parts to ensure the welds are firm, without incomplete welds, false welds, or welding defects. Functional testing: According to the requirements of the heat dissipation fins 200 to be welded, conduct performance tests on the heat dissipation fins 200 to ensure its heat dissipation effect and mechanical strength meet design specifications.

[0038] The fixture 100 provided in this application has the following advantages: (i) Simple operation: The fixture 100 is easy and quick to install and disassemble, requiring only one fixture on each side of the heat sink fin 201, simplifying the operation process. (ii) Efficient support: The multiple support members 20 with the comb-like structure can support multiple fins simultaneously, providing uniform lateral support and preventing the fins from bending and deforming during the welding process. (iii) Fin protection: The design of the fixture 100 reduces direct contact with the fin surface, lowering the risk of scratches or indentations on the fins. (iv) Strong adaptability: By adjusting the spacing and thickness of the multiple support members 20, the fixture 100 can be applied to heat sink fins 201 of different specifications, exhibiting good versatility.

[0039] In other embodiments of this application, the tooling 100 can be applied to various parts to be processed with similar structural requirements, such as: (1) Circuit board plug-in support in electronic devices: When the circuit board is plugged in for soldering, the pins of many small electronic components need to be kept in a stable position to ensure the accuracy and reliability of the soldering. Since these pins are densely arranged and easily deformed after being heated, the tooling 100 can be inserted into the gap between adjacent pins to prevent the pins from being displaced or deformed under the high temperature of soldering and the action of external force. (2) Metal sheet parts in precision machining: When processing precision parts such as micro springs and metal thin film sensors, the tooling 100 can be placed between adjacent sheets to ensure the neat arrangement and processing stability of the sheets and avoid deformation caused by thermal stress or mechanical stress. (3) Assembly and bonding of composite material plates: In the fields of aerospace, automobile manufacturing, etc., small composite material plates need to be precisely spaced during the bonding or assembly process. The tooling 100 can be spaced to avoid shape changes or structural damage caused by mutual squeezing or uneven force. (4) Installation of optical components: In the manufacturing process of optical equipment, such as the installation of gratings and filters, tooling 100 can be used for support and positioning to ensure the flatness and spacing accuracy of optical components.

However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
