Description

Technical Field

[0001] This invention relates to the field of precision metal machining technology, specifically to a radiator processing method, a radiator, and processing equipment. Background Technology

[0002] The shaving process is a key technology in manufacturing integrated heat sinks. Heat sinks made using this process have excellent thermal conductivity due to the absence of interfacial thermal resistance between the substrate and the fins, and are widely used in new energy vehicles, high-power electronic devices, and industrial control fields. Traditional shaving processes typically involve continuously shaving thin-walled fins directly from a metal blank.

[0003] However, with the continuous increase in the power density of heat sinks, the requirements for thinner and denser fins are also becoming increasingly stringent. During the manufacturing process, the extremely thin-walled fins themselves have poor rigidity and are easily deformed by bending, collapsing, or even tearing due to the combined effects of cutting forces, cutting heat, and the release of internal material stress, leading to product scrap. To solve this problem, some industry solutions propose first manufacturing a support structure with a certain strength, and then manufacturing the fins, using the support structure to laterally constrain the fins.

[0004] While the above solutions alleviated the fin collapse problem to some extent, new technical challenges arose. The semi-finished radiator, after being shaped by cutting, typically requires subsequent finishing processes such as end face trimming and contour shaping. These processes generate a large amount of fine metal shavings, which easily fly off and become stuck in the narrow gaps between the fins. These shavings are not only difficult to clean, but more seriously, they can scratch and abrade the thin-walled fins in the high-frequency vibration of the processing environment, directly leading to substandard product appearance and performance.

[0005] Furthermore, the scraping process itself requires the application of significant cutting forces, while conventional vacuum chuck clamping methods often lack sufficient clamping rigidity for large or thin metal blanks. This leads to minute displacements and vibrations in the workpiece during processing, directly impacting the scraping accuracy and the dimensional consistency of the final product. Simultaneously, in traditional single-station operation modes, in-machine processing and external auxiliary operations can only be performed sequentially, resulting in short effective processing time, slow overall production cycle time, and difficulty in meeting the demands of large-scale production. Summary of the Invention

[0006] To address the technical problems in existing technologies, such as easy deformation during thin-walled fin processing, chip contamination during finishing processes, insufficient workpiece clamping rigidity, and low production efficiency, this invention provides a radiator processing method, a radiator, and processing equipment.

[0007] The present invention provides a radiator processing method, comprising: S1, clamping the workpiece; S2, using a first scraping tool to scrape a beveled surface on the workpiece as a reference surface; S3, using a second scraping tool to scrape a plurality of support plates on the workpiece; S4, using the first scraping tool to scrape a plurality of fins behind the support plates, repeating S3 and S4 to obtain a radiator in which the base plate, fins and support plates are integrally formed; S5, performing fine finishing on the radiator.

[0008] In one embodiment, in S3, the second cutting tool cuts the reference inclined plane once at a first entry angle to form the support piece.

[0009] In one embodiment, in S3, the second cutting tool first cuts a notch on the reference inclined surface at a second cutting angle, and then cuts from the notch at a third cutting angle to form the support piece.

[0010] In one implementation, in step S3, a third shaving tool is first used to carve a pre-opened notch on the reference inclined surface, and then a second shaving tool is used to carve the support piece within the pre-opened notch. The width of the pre-opened notch is greater than the width of the support piece. This solution addresses the problem of burrs appearing at the cutting position due to workpiece rotation and misalignment.

[0011] In one embodiment, the angle between the reference inclined plane and the horizontal plane is α1, the entry angle of the second cutting tool when cutting out the notch is α2, and the entry angle of the second cutting tool when cutting out the support piece is α3, satisfying: α2 > α3 > α1. Preferably, α2 is 30°~60° and α3 is 5°~20°, but the present invention is not limited thereto.

[0012] In one embodiment, in S1, clamping the workpiece includes: initially positioning the workpiece by vacuum adsorption, spraying liquid onto the contact surface between the workpiece and the suction cup, and cooling the liquid to freeze it into an ice layer to enhance clamping rigidity.

[0013] In one embodiment, after the support piece is shaped by the second cutting tool, the overall outline of the support piece is triangular, and the thickness at the root of the support piece is greater than the thickness at the top. This shape is determined by the tool's entry angle, tip shape, and feed direction, and is an inevitable result of the process.

[0014] In one embodiment, the first shovel cutting tool and the second shovel cutting tool are each equipped with an independent telescopic drive device.

[0015] In one embodiment, in step S5, before the heat sink is finished, a curable phase change medium is introduced into the gap between the fins and cured to form a solid protective barrier in the gap; the heat sink is finished while the solid protective barrier is blocking the gap; after the finish, the solid protective barrier is removed.

[0016] In one embodiment, the phase change medium is water, and the solid protective barrier is ice; the solid protective barrier can be removed by means of standing at room temperature, hot air purging, or heating to melt, combined with high-pressure gas purging.

[0017] In one implementation, the method employs a dual-station alternating operation mode, where at one station, while shaving and finishing are performed, at least one of clamping, forming a solid protective barrier, or removing a solid protective barrier is performed simultaneously at the other station.

[0018] The present invention also provides a heat sink, comprising: a base plate; a plurality of fins integrally extending upward from the base plate; a plurality of support plates integrally formed with the base plate and the fins, and disposed between adjacent fins; the ends of the support plates abutting or not abutting with adjacent fins; the root thickness of the support plate is greater than the top thickness; the support plates and the fins are integrally formed by a shaving process.

[0019] Preferably, the overall outline of the support sheet is triangular.

[0020] The present invention also provides a radiator processing equipment, comprising: a frame; a processing table disposed on the frame; a processing mechanism including a first scraping tool and a second scraping tool, wherein the first scraping tool is used to scrape a reference surface and fins, and the second scraping tool is used to scrape a support plate; the first scraping tool and the second scraping tool are respectively provided with independent telescopic drive devices; the radiator processing equipment is configured to perform the above processing method.

[0021] Compared with the prior art, the present invention has the following beneficial effects: First, by using a step-by-step scraping process, a support plate is formed first, and then a thin-walled fin is formed. The integrally formed support plate provides effective lateral support for the thin-walled fin, which solves the technical problem that the thin-walled fin is prone to collapsing and deformation during processing and use.

[0022] Secondly, by using three different shaving schemes, the processing requirements of support plates of different heights can be adapted, and the problem of burrs caused by workpiece rotation and misalignment at the cutting position can be solved.

[0023] Third, by optimizing the design of the angle relationship α2 > α3 > α1, the thickness at the root of the support plate is ensured to be greater than the thickness at the top, thereby improving the support strength.

[0024] Fourth, the composite workpiece clamping method combining vacuum adsorption and interface icing significantly improves clamping rigidity, effectively suppresses workpiece vibration and micro-displacement under large cutting forces, and ensures machining accuracy.

[0025] Fifth, by introducing a dual-station rotation operation mode, parallel processing of in-machine processing and external auxiliary operations is achieved, which greatly shortens the production cycle and improves equipment utilization and production efficiency. Attached Figure Description

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0040] In traditional scraping processes, when directly scraping thin-walled fins, the fins themselves have poor rigidity and are prone to bending, collapsing, and other deformation problems under the influence of cutting forces, heat, and vibration. Furthermore, during the finishing trimming process after fin array formation, metal chips easily fall into and become stuck in the narrow gaps between the fins, making them difficult to clean and potentially scratching the fin surface, leading to product scrap. This invention provides an innovative processing method, equipment, and product designed to systematically solve the above problems. Its core idea is twofold: firstly, through a structural design of "step-by-step scraping and forming an integrated lateral support," the structural stability of thin-walled fins during processing and use is fundamentally enhanced; secondly, a "ice-solid anti-corrosion finishing" process is introduced, which utilizes a solidifiable phase change medium to temporarily fill and seal the gaps between the fins before finishing, forming a physical barrier and thus eliminating the risk of chip contamination.

[0041] Reference Figure 1This invention provides a radiator processing method, the overall process of which follows a rigorous technological sequence. First, the metal blank is positioned and clamped using a composite workpiece clamping device. This device combines vacuum adsorption with interface icing to provide a highly rigid foundation for subsequent high-cutting-force machining. Next, the clamped blank is CNC pre-shaped, with basic contours and steps milled to provide a unified and precise machining benchmark for subsequent precision shavings. Then, the core step-by-step shaving and shaping stage begins. This stage includes two consecutive shaving steps: first, spaced support plates of a certain width are shaving out; then, thinner, thin-walled fins are shaving out between these support plates, allowing the support plates to provide integrated lateral support for the thin-walled fins. After shaving, the workpiece is moved outside the machine for ice-sealing treatment. Water, as a sacrificial filler material, is introduced into the gaps between the fins and frozen to form a solid protective barrier. Afterward, the workpiece, still with the barrier in place, is returned to the machine for precision cutting. The solid barrier effectively prevents chips from entering the fin gaps. Finally, post-processing is performed, melting and removing the solid protective barrier, and cleaning the workpiece to obtain a clean, high-precision finished heat sink.

[0042] The following will combine Figure 1 , Figures 6 to 9 The process steps described above are explained in detail.

[0043] The first step is blank positioning and clamping. A metal blank 10, made of materials such as high-purity aluminum, aluminum alloy, or copper, is selected and placed on a composite workpiece clamping device. The clamping process consists of two steps: First, the vacuum circuit is activated, using negative pressure to ensure that the reference surface of the metal blank 10 is tightly pressed against the working surface of the device, achieving preliminary precise positioning; then, the cooling circuit is activated, spraying water, which acts as a solidifiable phase change medium, onto the contact surface between the metal blank 10 and the device. The water rapidly solidifies at low temperatures, forming a solid bonding layer. This solid bonding layer greatly enhances the shear resistance between the workpiece and the device, thus providing excellent clamping rigidity for subsequent high-cutting-force processes such as shearing, and effectively suppressing micro-displacement and vibration of the workpiece during machining.

[0044] After clamping, the reference surface can be selectively machined. For example... Figure 6As shown, a bevel can be cut into the metal blank 10 using the first scraping tool 71 as a reference surface, providing a precise entry angle and positioning reference for subsequent scraping processes to ensure the perpendicularity of the fins and support plates. Subsequently, CNC pre-forming can be performed. The clamped metal blank 10 is fed into the machining area along with the worktable, and the overall shape and mounting steps of the blank are roughed and semi-finished by the CNC-controlled milling mechanism 9. The purpose of this step is to reserve precise machining allowances for subsequent scraping processes and establish a unified machining reference, thereby effectively avoiding the adverse effects of the original blank's dimensional or shape tolerances on subsequent high-precision scraping processes, ensuring the consistency and stability of the final product dimensions.

[0045] Next, a step-by-step shaping process is performed, which is crucial for forming the core structure of the radiator. (Refer to...) Figure 2 , Figure 7 and Figure 8 This step is broken down into two consecutive sub-steps. First, the first shaving step is performed, as follows: Figure 7 As shown, the second scraping tool 72 is used to reciprocate scraping the surface of the metal blank 10 to form several support plates 102 arranged at a preset interval. To ensure sufficient support strength, the root thickness of the support plate 102 is greater than the top thickness, and the overall outline is triangular. It should be noted that the upper part of each of the multiple scraping tools in this patent is provided with a mechanism for extending and retracting the multiple scraping tools. The power principle for extension and retraction can be a pneumatic cylinder, an electric cylinder, or a hydraulic drive.

[0046] In this invention, the second cutting tool 72 cutting to form the support piece 102 has three optional solutions: Option 1: One-time cutting and shaping. The second cutting tool 72 cuts out the support piece 102 in one go on the reference inclined surface with a large entry angle, which is suitable for short support pieces.

[0047] Option 2: Two-stage cutting. The second cutting tool 72 first cuts out a notch at a larger entry angle, and then cuts out the support piece 102 from the notch at a smaller entry angle. This is suitable for high support pieces.

[0048] Option 3: Wide-blade pre-cut notch, narrow-blade scraping shaping. First, the third scraping tool 73 is used to scrape a pre-cut notch on the reference inclined surface. Then, the second scraping tool 72 is used to scrape out the support piece 102 within the pre-cut notch. The width of the pre-cut notch is greater than the width of the support piece 102. This option is used to solve the problem of burrs at the cutting position caused by workpiece rotation and misalignment.

[0049] In the above scheme, the angle between the reference inclined plane and the horizontal plane is α1, the entry angle of the second cutting tool 72 when cutting out the notch is α2, and the entry angle of the second cutting tool 72 when cutting out the support piece 102 is α3, satisfying: α2 > α3 > α1. Preferably, α2 is 30°~60° and α3 is 5°~20°, but the present invention is not limited thereto.

[0050] After the support plate 102 is machined, the second cutting tool 72 retracts, and then the first cutting tool 71 extends to perform the second cutting step, as follows. Figure 8 As shown, multiple precise reciprocating shearing operations are performed within the reserved area between two adjacent support plates 102 to form multiple densely arranged thin-walled fins 101. In this way, the support plates 102, the thin-walled fins 101, and the base plate 100 form a seamless integral structure. After forming, the lateral end faces of the support plates 102 can abut against or be adjacent to the sides of adjacent thin-walled fins 101, thereby providing effective lateral support and restraint, greatly restricting the space for bending deformation of the thin-walled fins 101 during processing or subsequent use, fundamentally solving the problem of fin collapse.

[0051] After the workpiece is shaped by the cutting process, an external ice-sealing treatment is performed. The workpiece, after the step-by-step cutting, has formed an array of fins with numerous narrow gaps. At this point, the worktable carrying the workpiece is moved out of the machining area inside the machine tool and sent to an external auxiliary ice-sealing station. At this station, water is injected as a sacrificial filler into all the gaps between the thin-walled fins 101. Using the ambient low temperature or the station's own refrigeration system, the injected water freezes rapidly, forming a dense, solid protective barrier within all the fin gaps. This solid protective barrier completely fills and seals all the hollowed-out areas between the fins, creating a crucial prerequisite for subsequent anti-corrosion finishing.

[0052] Subsequently, ice-sealed finishing is performed. The ice-sealed workpiece is then fed back into the machine tool's machining area. Since all fin gaps are now completely sealed by a solid protective barrier, the workpiece's end faces and overall contours can be safely finished with final milling and finishing. A large amount of metal chips generated during the finishing process fall onto the surface of the solid protective barrier and are effectively blocked, preventing them from falling into and getting stuck in the narrow fin gaps. This "ice-sealed finishing" method eliminates the problem of chips scratching the fin surface or remaining in the gaps and being difficult to clean, significantly improving product yield and appearance cleanliness. Because water, as the sacrificial filler material, is inert, the solid protective barrier it forms will not cause any chemical damage to the heatsink's metal substrate.

[0053] Finally, post-processing is performed. After fine trimming, the workpiece is removed from the machining area again. The solid protective barrier filling the gaps between the fins is melted using methods such as room temperature resting, hot air blowing, or localized heating. Subsequently, high-pressure gas blowing can be used to remove the melted water and all machining chips adhering to the workpiece surface. Depending on product requirements, subsequent processes such as deburring, cleaning, and drying can be added. At this point, the final finished heat sink is obtained. Figure 9 As shown, the finished product includes a base plate 100, and thin-walled fins 101 and support plates 102 integrally formed with the base plate 100. The support plates 102 are spaced apart in the fin array and provide lateral support to adjacent thin-walled fins 101, resulting in a stable structure and a clean surface.

[0054] To implement the above method, the present invention also provides a corresponding radiator processing apparatus. (Refer to...) Figure 3 , Figure 4 , Figure 10 and Figure 11 The equipment mainly includes a frame 1, and a translation mechanism, a machining mechanism 7, and a composite workpiece clamping device mounted on the frame 1. The translation mechanism may include a Y-axis translation mechanism 2 that moves laterally and longitudinally, and a Z-axis translation mechanism 3 that moves vertically. They typically employ high-precision ball screw drives and are equipped with displacement sensors to precisely control the movement trajectory and positioning of the cutting tool. The machining mechanism 7 is fixed to the lower end of the translation mechanism and moves synchronously with it.

[0055] Reference Figure 5 The machining mechanism 7 is the core component for performing the scraping operation. In a preferred embodiment, it integrates a first scraping tool 71 and a second scraping tool 72. These two tools are each equipped with an independent telescopic drive device, allowing them to extend independently to perform machining or retract to standby according to program instructions, without interfering with each other, thus efficiently completing step-by-step scraping. Specifically, when scraping dense fins, the telescopic device of the first scraping tool 71 can coordinate with the main Z-axis of the machine tool to form a composite feed, thereby achieving rapid, micro-precision control of the scraping depth and speed to meet the continuous forming requirements of dense thin-walled fins. The cutting edge of the second scraping tool 72 can be provided with a specific raised forming profile to process a support piece 102 with a specific shape. Correspondingly, the first scraping tool 71 uses a straight cutting edge to ensure that thin-walled and regular fins 101 can be processed. As a more efficient configuration, such as... Figure 12 As shown, the processing mechanism 7 can also be equipped with a vertical multi-head scraper assembly 73 to achieve synchronous scraping operations of multiple fins, greatly improving production efficiency.

[0056] The technical solution of this patent allows for the installation of either a vertical or horizontal scraper, depending on the user's needs, providing a choice to meet different processing requirements.

[0057] A composite workpiece clamping device is mounted on the machining table 4 to fix the metal blank 10. This device integrates a vacuum adsorption circuit and a water mist cooling and icing circuit. The vacuum circuit creates negative pressure on the suction cup surface to firmly adsorb the metal blank 10 and achieve datum positioning. The water mist cooling and icing circuit sprays low-temperature water onto the bottom surface of the blank, causing it to freeze and form a solid bonding layer, thus providing strong secondary reinforcement and significantly improving clamping rigidity. In addition, the equipment includes a drive system that electrically controls the translation mechanism, machining mechanism 7, composite workpiece clamping device, and other auxiliary components to work together automatically to complete the entire machining process.

[0058] In some more complex implementations, the equipment can also be configured with other functional modules to enhance its machining capabilities and level of automation. For example, an A-axis rotation mechanism 5 and a B-axis tilting mechanism 6 can be configured to adjust the workpiece's posture during machining, thereby enabling machining of multiple surfaces or complex angles of the workpiece. The equipment can also be equipped with a tool magazine 8 and a separate milling cutter mechanism 9. The tool magazine 8 is used to store and automatically change various tools, including milling cutters and scrapers, while the milling cutter mechanism 9 is dedicated to performing CNC pre-forming and final finishing trimming processes.

[0059] Another important optimization is the adoption of a dual-station alternating operation mode. In this mode, the machine's worktable is equipped with two independent stations, such as station A and station B. While the workpiece at station A is undergoing a time-consuming machining operation inside the machine tool, station B simultaneously performs shorter auxiliary operations in an auxiliary area outside the machine tool. These operations include clamping and calibrating new blanks, or de-icing, blowing, cleaning, and unloading finished products. After one machining cycle, the two stations are exchanged via a translation or rotation mechanism. Station B enters the machine for machining, while station A moves out for auxiliary operations. This parallel operation method allows the machine tool's machining spindle to operate with almost no downtime, greatly shortening the production cycle time per unit, significantly improving equipment utilization and overall production efficiency, and is particularly suitable for large-scale mass production needs.

[0060] Furthermore, for complex heat sinks requiring the processing of multi-faceted fin arrays, a rotary drive component can be integrated into the composite workpiece clamping device. This allows the metal blank 10 to be rotated by a preset angle after fin cutting in one direction, and then the step-by-step cutting process can be repeated in the new direction, thereby forming a multi-directionally arranged fin structure on the same blank, greatly expanding the applicability of the process.

[0061] This invention also covers some simplified implementation schemes. For example, if the purchased metal blank 10 has already been pre-machined with a compliant reference surface, it can be directly clamped on-site, omitting the step of scraping the reference surface and simplifying the process. Similarly, in terms of equipment configuration, a single-station equipment without a dual-station switching structure can also be used. Although the production efficiency of this simplified scheme is relatively low, it can still fully realize the core processes of composite clamping, step-by-step scraping, external ice sealing, and ice-covered finishing, and can also effectively solve the key technical problems of fin collapse and chip jamming during finishing, and therefore also fall within the protection scope of this invention.

[0062] The radiator product manufactured by this invention also has unique structural features. For example... Figure 9 As shown, the radiator includes a base plate 100 and multiple thin-walled fins 101 integrally extending upward from the base plate 100. The key difference lies in the fact that several support plates 102 are integrally formed between these thin-walled fins 101. The sides of these support plates abut or are adjacent to the adjacent thin-walled fins 101, not only increasing the overall heat dissipation surface area but, more importantly, providing structural support for the originally fragile thin-walled fins, significantly improving the overall mechanical strength and vibration and impact resistance of the radiator. The root thickness of the support plate 102 is greater than its top thickness, and its overall outline is triangular. This shape is determined by the cutting tool's entry angle, tip shape, and feed direction, and is an inevitable result of the manufacturing process.

[0063] In summary, this invention, through synergistic innovation in structure and process, not only retains the structural stability advantages of the "support first, fin later" approach, but also completely solves the industry pain point of chip jamming during fine finishing through its unique "ice-solid anti-corrosion" method. Combined with high-rigidity composite clamping technology and an efficient dual-station operation mode, this invention provides a technologically advanced, highly reliable, and mass-producible heat sink processing solution, which is of great significance to the development of heat dissipation technology in high-power electronic devices and the new energy field. The above description is merely a preferred embodiment of this invention and is not intended to limit the invention. Various modifications and variations can be made to this invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
