Technical Field

[0001] The present application relates to the field of heat pipe processing equipment, and in particular to a liquid wick biased heat pipe processing equipment and a processing technology. Background Art

[0002] In the current computer hardware world, CPU cooling performance is crucial for stable operation and optimal performance. Currently, air cooling remains the mainstream cooling method for consumer-grade CPUs. Heat pipes, as key components in air-cooled cooling modules, are responsible for efficiently transferring heat generated by the CPU to the cooling fins. Their processing directly determines their heat transfer performance, which in turn affects the overall cooling effect of the entire cooling module.

[0003] The related art discloses a preparation method of a high-temperature heat pipe liquid wick, which includes the following steps: step 1, straightening the hollow tube shell, selecting a hollow tube shell and performing a straightening operation; step 2, winding the support layer, selecting a support layer, and winding the support layer on the central mold; step 3, fitting the support layer, inserting the central mold with the wrapped support layer into the hollow tube shell, and after the support layer is tightly fitted to the inner wall of the hollow tube shell, pulling out the central mold; step 4, installing the right plug, installing the right plug at the right end of the hollow tube shell; step 5, adjusting the size of the central mold, inserting the central mold into the hollow tube shell again, adjusting the size of the central mold, and determining the size of the gap between the central mold and the support layer; step 6, filling the porous layer material, adding metal, alloy powder or Fiber is filled in the gap between the central mold and the supporting layer, and the filler is the component material of the porous layer; step seven, installing the left plug, and installing the left plug on the left end of the hollow tube shell; step eight, high-temperature sintering, placing the assembly of the hollow tube shell, supporting layer, porous layer, central mold, left plug and right plug in a sintering furnace for high-temperature sintering, and introducing a reducing protective atmosphere or an inert protective atmosphere or vacuum sintering during the sintering process, and the supporting layer and the porous layer are metallurgically combined to form a high-temperature heat pipe liquid wick; step nine, removing the high-temperature heat pipe liquid wick, after the sintering operation is completed, first, remove the left plug and the right plug of the hollow tube shell assembly; then, remove the central mold; finally, remove the high-temperature heat pipe liquid wick from the hollow tube shell to complete the preparation of the high-temperature heat pipe liquid wick.

[0004] The positioning accuracy of the brazing rod in the copper tube mainly depends on the guarantee of the shrink tube side. The longer the shrink tube length and the smaller the difference between the brazing rod and the inner diameter of the shrink tube, the more fixed the position of the brazing rod, and the higher the consistency of the structure and performance of the heat pipes in the same batch. However, an overly long eccentric tube section will cause waste of raw materials. In actual production, the length of the eccentric tube section is limited, which causes a certain degree of randomness in the position of the brazing rod in the copper tube. The preparation method of the high-temperature heat pipe wick in the related art cannot realize the processing of such biased heat pipes. Summary of the Invention

[0005] In order to overcome the problem that the position of the brazing rod in the copper tube in the traditional preparation method is random due to excessive reliance on the shrinkage side, resulting in poor consistency in the structure and performance of heat pipes in the same batch and inability to meet the high positioning precision processing requirements of the brazing rod for the liquid wick biased heat pipe, the present application provides a liquid wick biased heat pipe processing equipment and processing technology.

This design cleverly combines the storage of a large number of brazing rods with the orderly unloading function, which not only ensures an adequate supply of brazing rods, but also ensures that the brazing rods are output one by one and in an orderly manner through the screening mechanism, effectively avoiding the confusion and operational errors caused by the simultaneous falling of multiple brazing rods, and providing a reliable guarantee for the subsequent transfer insertion mechanism to accurately and efficiently obtain the brazing rods, thereby improving the automation and accuracy of the brazing rod insertion link in the entire liquid-wick biased heat pipe processing process, which helps to improve production efficiency and product quality stability.

The linkage 163 is fixedly connected to the second sliding seat 15. The first screw rod 162 passes through the linkage 163, and the first screw rod 162 and the linkage 163 are threadedly engaged. When the first motor 161 is working, it drives the first screw rod 162 to rotate. Since the first screw rod 162 and the linkage 163 are threadedly engaged, the second sliding seat 15 is driven to move along the second direction, thereby adjusting the position of the tube shrinking mechanism 18 in the second direction and ensuring the accuracy of the tube shrinking process.

The lifting seat 171 slides in conjunction with the second sliding seat 15. The bearing block 172 is fixed to the second sliding seat 15. The lifting drive 173 is disposed on the bearing block 172 and is used to drive the lifting seat 171 up and down. The specific lifting drive can be a cylinder, hydraulic, or motor screw structure. Driven by the lifting drive 173, the lifting seat 171 can be raised and lowered in the vertical direction, thereby adjusting the height of the tube reduction mechanism 18 to accommodate the processing requirements of pipes 41 of different diameters.

[0045] Continue to refer to Figure 4 To ensure smooth and accurate movement between components, guide mechanisms are installed between the first sliding seat 13 and the first frame 11, between the second sliding seat 15 and the first sliding seat 13, and between the lifting seat 171 and the second sliding seat 15. These guide mechanisms include guide rails and sliders. The guide rails utilize high-precision linear guides, and the sliders are fixedly connected to the corresponding components. The cooperation between the guide rails and sliders achieves precise guidance between the components, reduces friction and vibration during movement, and improves machining accuracy.

The second positioning groove 1243 has the same shape as the first positioning groove 1211 and is symmetrical to each other. The first clamping block 1241 is driven down by the first lifting cylinder 1242. When the bottom end of the first clamping block 1241 abuts against the top end of the first positioning block, the first clamping block 1241 and the first positioning block have a clamping effect on the pipe 41, ensuring the stability of the pipe 41 during the tube shrinking process.

The upper surface of the first base 221 is provided with a third positioning groove 2211 and a fourth positioning groove 2212 that are interconnected. The third positioning groove 2211 and the fourth positioning groove 2212 both extend along the first direction. The depth of the third positioning groove 2211 is greater than that of the fourth positioning groove 2212, and both are semicircular grooves. The third positioning groove 2211 is used to position the original tube section 411 and is located on the side of the first base 221 close to the second support base 222. The fourth positioning groove 2212 is used to position the eccentric tube section 412 and is located on the side of the first base 221 close to the transfer insertion mechanism 23. The second tube clamping mechanism 22 positions the original tube section 411 and the eccentric tube section 412 respectively through the third positioning groove 2211 and the fourth positioning groove 2212, and can accurately clamp and fix the tube 41 after shrinkage, providing stable support for the insertion of the drill rod 42, ensuring the accuracy and reliability of the insertion of the drill rod 42.

The piston rod of the second lifting cylinder 224 passes through the second support base 222 and slides with the second support base 222. The piston rod of the second cylinder is fixedly connected to the clamping block 223. The lower surface of the clamping block 223 is provided with a fifth positioning groove 2231 and a sixth positioning groove 2232. The fifth positioning groove 2231 is used to position the original pipe section 411, and the sixth positioning groove 2232 is used to position the eccentric pipe section 412. The fifth positioning groove 2231 and the sixth positioning groove 2232 both extend along the first direction and are semicircular grooves. The depth of the fifth positioning groove 2231 is greater than that of the sixth positioning groove 2232. The difference in size and structure between the original pipe section 411 and the eccentric pipe section 412 enables more precise positioning of the two. When the second lifting cylinder 224 is in operation, its piston rod drives the clamping block 223 to move up and down. During the descent process, the fifth and sixth positioning grooves 2231 and 2232 correspond to the third and fourth positioning grooves 2211 and 2212, respectively, on the first base 221. The fifth and third positioning grooves 2231, in conjunction with the third and fourth positioning grooves 2211, accurately clamp and secure the original pipe section 411 within the circular positioning space formed by the five positioning grooves 2231 and 2211. The sixth and fourth positioning grooves 2232, in conjunction with the fourth and fourth positioning grooves 2212, accurately clamp and secure the eccentric pipe section 412 within the circular positioning space formed by the six positioning grooves 2232 and 2212.

The two material storage plates 2412 are both fixed to the side of the first support plate 2411 close to the transfer insertion mechanism 23. The first support plate 2411 and the two material storage plates 2412 enclose a material cavity, and the top and bottom ends of the cavity are both open. The screening assembly 242 is set at the bottom of the cavity. During operation, the screening assembly 242 only allows one drill rod 42 in the cavity to fall into the material receiving assembly 243 at a time.

The second driving member 2423 is arranged on the first support plate 2411, and the second driving member 2423 is used to drive the screening column 2422 to rotate. During the rotation process, only one drill rod 42 falls into the material receiving assembly 243 at a time. The screening assembly 242 achieves the function of allowing only one drill rod 42 to fall at a time through the rotation of the screening column 2422 and the screening groove 2424, ensuring the accuracy and orderliness of the discharge of the drill rod 42, avoiding the confusion and failure caused by the simultaneous falling of multiple drill rods 42, and improving the processing quality and production efficiency.

[0053] Continue to refer to Figure 5 It is worth noting that there is a gap between the bottom ends of the two storage plates 2412 and the screening column 2422, with the gap size controlled to be between 0.5-1 mm. This prevents interference between the screening column 2422 and the two storage plates 2412 during rotation. At the same time, the small gap between the bottom ends of the storage plates 2412 and the screening column 2422 prevents the rods between the two storage plates 2412 from slipping through the gap onto the surface of the second workbench, ensuring stable storage and normal unloading of the brazing rods 42.

The upper surface of the material receiving block 2431 is provided with a seventh positioning groove 2433 for positioning the drill rod 42. The bottom ends of the two guide blocks 2432 are fixedly connected to the material receiving block 2431. The two guide blocks 2432 are both tilted, and the tilt angle is generally 30°-45°. The spacing between the tops of the two guide blocks 2432 is greater than the spacing at the bottom. The top spacing is designed according to the bottom opening size of the material chamber and the possible falling range of the drill rod 42 to ensure that the drill rod 42 after screening by the screening assembly 242 can smoothly fall between the guide blocks 2432; the bottom spacing is adapted to the width of the seventh positioning groove 2433 to ensure that the drill rod 42 can accurately fall into the seventh positioning groove 2433. The material receiving assembly 243 realizes accurate material receiving and positioning of the drill rod 42 through the seventh positioning groove 2433 of the material receiving block 2431 and the inclined setting of the guide block 2432, ensuring that the drill rod 42 can accurately enter the subsequent processing link, thereby improving the accuracy and stability of the processing.

When the second motor 2322 is started, the output shaft drives the driving bevel gear 2323 to rotate. The driving bevel gear 2323 transmits power to the driven bevel gear 2324, thereby driving the rotating rod 2312 to rotate. The bevel gear transmission has the advantages of stable transmission ratio, high transmission efficiency, and compact structure, and can reliably transmit the rotational motion of the second motor 2322 to the rotating rod 2312. When the driven bevel gear 2324 drives the rotating rod 2312 to rotate, the rotating rod 2312 drives the rotating disk 2311 to rotate synchronously, thereby transmitting the rotational motion of the second motor 2322 to the insertion assembly 233 disposed on the rotating disk 2311.

[0058] Continue to refer to Figure 5 The adjustment seat 2321 is provided with four adjustment slots 2325 extending horizontally. Each adjustment slot 2325 is threaded with a bolt, which is threadedly engaged with the second frame 21. By adjusting the position of the bolt within the adjustment slot 2325, the second motor 2322 can be fine-tuned horizontally to ensure good meshing between the driving bevel gear 2323 and the driven bevel gear 2324, thereby reducing vibration and noise during transmission and improving transmission accuracy and stability.

The two clamping components of the clamping cylinder 2332 are each provided with a positioning groove. The radius of the positioning groove matches the radius of the drill rod 42. The surface of the positioning groove is coated with a rubber material. The rubber material has good elasticity and friction, which can increase the contact area with the drill rod 42, improve the firmness of the clamping, and prevent the drill rod 42 from slipping or shaking during the insertion process. The clamping components of the clamping cylinder 2332 are opened and closed through pneumatic control, which can quickly and accurately clamp and release the drill rod 42.

The receiving block 2431 of the receiving assembly 243 is accurately positioned for receiving the material through the seventh positioning groove 2433 and the two inclined guide blocks 2432; the rotating drive assembly 232 of the transfer insertion mechanism 23 drives the active bevel gear 2323 and the driven bevel gear 2324 through the second motor 2322, and then drives the rotating seat 231 to rotate, and rotates the insertion assembly 233 carrying the drill rod 42 to the side close to the second clamping mechanism 22. The driving cylinder 2331 of the insertion assembly 233 pushes the clamping cylinder 2332 to move toward the pipe 41. The clamping cylinder 2332 uses the clamping component with the rubber-coated positioning groove to clamp the drill rod 42 and accurately insert it into the clamped and fixed pipe 41.

[0061] Continue to refer to Figure 5 and Figure 6 After the brazing rod 42 is inserted into the eccentric section 412 of the tube 41, the second clamping mechanism 22 releases its grip on the tube 41. The worker removes the tube 41 with the brazing rod 42 inserted from the second clamping mechanism 22. Then, manually or automatically, four positioning fins 43 of different shapes are sequentially installed inside the original tube section 411, away from the eccentric section 412, to further secure the brazing rod 42. Copper powder is then poured in and sintered at high temperature to form the wick.

Two second support plates 312 are fixedly installed at the bottom of the sintering mechanism 311. The bottom of the sintering mechanism 311 is open. A heating element is installed inside the sintering mechanism 311 to provide a high-temperature sintering environment. The inner side walls of the two second support plates 312 are each provided with a lifting and towing mechanism 33. Each lifting and towing mechanism includes a third motor 331, a second screw rod 332, a support seat 333 and two second supports 334. One of the second supports 334 is fixed to the inner side wall of the sintering mechanism 311, and the other second support 334 is fixed to the inner side wall of the second support plate 312. The second screw rod 332 extends in the vertical direction. The two ends of the second screw rod 332 are respectively rotatably connected to the two second supports 334. The third motor 331 is fixed to the inner side wall of the second support plate 312 and is fixedly connected to the bottom end of the second screw rod 332.

Each rotating roller 322 extends along the first direction, and each rotating roller 322 is fixedly mounted with two feed wheels 323, which are spaced apart. A protective cover 324 is provided on one side of the second base 321. A belt mechanism is provided within the protective cover 324, and the plurality of rotating rollers 322 are linked together by the belt mechanism to ensure synchronous rotation. A fourth motor 325 is fixedly mounted on the outer wall of the protective cover 324, and the output shaft of the fourth motor 325 is fixedly connected to the end of one of the rotating rollers 322.

[0064] Reference Figure 7 The second base 321 is provided with a material blocking mechanism 34, which includes a third lifting cylinder 341 and a material blocking member 342. The third lifting cylinder 341 is fixed to the second base 321, and the piston rod of the third lifting cylinder 341 is fixedly connected to the material blocking member 342. When the pipe 41 is transported to the designated position by the feeding wheel 323, the third lifting cylinder 341 is activated, driving the material blocking member 342 to rise, preventing the pipe 41 from moving further, and ensuring that the container containing multiple pipes 41 is directly below the sintering mechanism 311. After sintering is completed, the third lifting cylinder 341 drives the material blocking member 342 to descend, releasing the pipe 41, so that the container containing multiple pipes 41 can be smoothly sent out of the sintering mechanism 31 by the feeding wheel 323.

[0065] Multiple tubes 41, which have been inserted with brazing rods 42 and filled with copper powder, are placed simultaneously in a heat-conducting container, and then the container is placed on the feed wheel 323 of the horizontal feed mechanism 32. The fourth motor 325 is started, driving all the rotating rollers 322 to rotate synchronously through the belt mechanism, and then driving the feed wheel 323 to feed the tubes 41 into the sintering mechanism 31. When the tubes 41 are transported to the designated position, the third lifting cylinder 341 of the blocking mechanism 34 is started, driving the blocking member 342 to rise, preventing the tubes 41 from moving further. The third motor 331 of the lifting and transporting mechanism 33 is started, driving the second screw 332 to rotate through the reducer, and then driving the supporting seat 333 to rise, lifting the tubes 41 to the sintering area in the sintering mechanism 31. The heating element is started, and the tubes 41 are sintered at high temperature, so that the copper powder is sintered to form a liquid-absorbing core. After sintering is completed, the heating element is turned off, and the third motor 331 of the lifting and transporting mechanism 33 rotates in the opposite direction, driving the support seat 333 to descend, and sending the tube 41 out of the sintering area. The third lifting cylinder 341 of the blocking mechanism 34 drives the blocking member 342 to descend, releasing the tube 41. The third motor 331 continues to start, and the feeding wheel 323 sends the tube 41 out of the sintering mechanism 31, completing the entire sintering process. The implementation principle of the above embodiment is as follows: through the coordinated work of the tube shrinking device 1, the rod insertion device 2 and the sintering device 3, efficient processing of the liquid wick offset heat pipe 4 is achieved. The tube shrinking device 1 can accurately shrink the tube 41 to form an eccentric tube section 412, providing an accurate positioning basis for the insertion of the brazing rod 42. The rod insertion device 2 solves the problem of large randomness in the position of the brazing rod 42 in the traditional method through automated storage, unloading and insertion operations, improves the positioning accuracy of the brazing rod 42, and thus ensures the uniformity of the liquid wick. The sintering device 3 realizes high-temperature sintering of the tube 41, so that the copper powder is sintered to form a liquid wick, thereby improving the heat transfer performance of the heat pipe. The entire equipment improves the quality and production efficiency of heat pipe processing through the reasonable combination and precise control of each device, meets the processing requirements of the liquid wick offset heat pipe 4 for high positioning accuracy of the brazing rod 42, and has been significantly improved and upgraded compared to traditional processing technology.

[0066] Example 2 This embodiment discloses a process for manufacturing a wick-biased heat pipe manufacturing device, comprising the following steps: S1: Pipe 41 shrinking process, the specific steps are as follows: 1. Place the tube 41 to be processed in the first tube clamping mechanism 12 of the tube shrinking device 1. Initially position the tube 41 using the first positioning groove 1211 on the positioning seat 121. The first positioning groove 1211 has a semicircular cross-section, with its length aligned with the first direction of the processing equipment, ensuring that the axis of the tube 41 is aligned with the processing direction.

[0067] 2. The first sliding drive mechanism 14 (the first drive member 142 is a cylinder or a hydraulic cylinder) drives the first sliding seat 13 to move in the first direction to adjust the position of the tube shrinking mechanism 18 in the first direction; the second sliding drive mechanism 16 (the first motor 161 drives the first screw 162) drives the second sliding seat 15 to move in the second direction to adjust the position of the tube shrinking mechanism 18 in the second direction; the lifting mechanism 17 (the lifting drive member 173 is a cylinder or a motor screw structure) drives the lifting seat 171 to rise and fall to adjust the height of the tube shrinking mechanism 18 so that the tube shrinking mold sleeve 181 is aligned with the part of the tube 41 to be processed.

[0068] 3. The multiple shrinking dies 181 of the shrinking mechanism 18 shrink one end of the tube 41 to form an eccentric tube section 412. During the shrinking process, the guide rails and sliders of the guide mechanism cooperate to ensure smooth and accurate movement between the components, reduce friction and vibration, and improve processing accuracy.

[0069] By precisely controlling the position of the tube reduction mechanism 18 in three directions (first, second, and vertical), one end of the tube 41 is precisely reduced, forming an eccentric tube segment 412. This provides a foundation for the subsequent insertion of the drill rod 42 and the formation of the wick. This improves the precision of the tube reduction process, ensuring the dimensional and shape accuracy of the eccentric tube segment 412, facilitating the subsequent positioning of the drill rod 42 and the formation of the wick. The use of the guide mechanism reduces friction and vibration during movement, thereby improving the stability and service life of the processing equipment.

[0070] S2: Insert the drill rod 42. The specific steps are as follows: 1. Place the shrunken tube 41 in the second tube clamping mechanism 22 of the rod insertion device 2. Use the third positioning groove 2211 and the fourth positioning groove 2212 on the first base 221 to position the original tube section 411 and the eccentric tube section 412, respectively. The second lifting cylinder 224 drives the clamping block 223 downward. The fifth and sixth positioning grooves 2231 and 2232 on the clamping block 223 engage with the third and fourth positioning grooves 2211 and 2212 on the first base 221, respectively, to precisely clamp and secure the tube 41.

[0071] 2. Multiple brazing rods 42 are stored in the material chamber of the storage and unloading mechanism 24. The screening column 2422 of the screening assembly 242 rotates under the drive of the second driving member 2423. The screening slot 2424 on the screening column 2422 allows only one brazing rod 42 to fall into the material receiving assembly 243 at a time. The material receiving block 2431 of the material receiving assembly 243 is precisely positioned for material receiving via the seventh positioning slot 2433 and two inclined guide blocks 2432.

[0072] 3. The rotary drive assembly 232 of the transfer insertion mechanism 23 drives the driving bevel gear 2323 and the driven bevel gear 2324 via the second motor 2322, which in turn drives the rotating base 231 to rotate, rotating the insertion assembly 233 carrying the drill rod 42 to the side close to the second pipe clamping mechanism 22. The drive cylinder 2331 of the insertion assembly 233 pushes the clamping cylinder 2332 toward the pipe 41. The clamping cylinder 2332 uses the clamping component with a rubber-coated positioning groove to clamp the drill rod 42 and accurately insert it into the eccentric pipe section 412 of the clamped and fixed pipe 41.

[0073] Through the precise clamping of the pipe 41 and the storage and unloading mechanism 24 for the brazing rod 42, as well as the rotation and insertion of the transfer insertion mechanism 23, the brazing rod 42 is precisely inserted into the eccentric pipe section 412 of the pipe 41. The rubber-coated positioning groove increases the friction between the clamping component and the brazing rod 42, improving the firmness of the clamping. This improves the accuracy and stability of the insertion of the brazing rod 42, ensures the accurate positioning of the brazing rod 42 within the pipe 41, and facilitates the subsequent formation of the wick and the improvement of the heat transfer performance of the heat pipe. The design of the screening component 242 and the material receiving component 243 ensures the accuracy and orderliness of the brazing rod 42 unloading, avoids the confusion and failure caused by the simultaneous drop of multiple brazing rods 42, and improves the processing quality and production efficiency.

[0074] S3: Position the fin 43 and install it. The specific steps are as follows: 1. After the drill rod 42 is inserted into the eccentric section 412 of the tube 41, the second clamping mechanism 22 releases its grip on the tube 41. The worker removes the tube 41 with the drill rod 42 inserted from the second clamping mechanism 22. Then, manually or automatically, four positioning fins 43 of different shapes are sequentially installed inside the original tube section 411, away from the eccentric section 412, to further secure the drill rod 42.

[0075] The installation of positioning fins 43 further secures the position of the brazing rod 42 within the tube 41, preventing movement of the brazing rod 42 during subsequent processing and use, thereby ensuring the stability and heat transfer performance of the heat pipe structure. This improves the stability of the heat pipe structure and reduces fluctuations in heat pipe performance caused by movement of the brazing rod 42. The four differently shaped positioning fins 43 better adapt to the shape of the interior of the tube 41, providing a more reliable fixation.

[0076] S4: Copper powder pouring and sintering, the specific steps are as follows: 1. Pour copper powder into the tube 41 with the brazing rod 42 inserted and the positioning fins 43 installed manually or automatically until the copper powder fills the area between the brazing rod 42 and the inner wall of the tube 41 (the wick area).

[0077] 2. Place multiple tubes 41 filled with copper powder in a heat-conducting container at the same time, and then place the container on the feeding wheel 323 of the horizontal feeding mechanism 32 of the sintering device 3.

[0078] 3. The third motor 331 starts, driving all the rotating rollers 322 to rotate synchronously via a belt mechanism, which in turn drives the feed wheel 323 to feed the tubes 41 into the sintering mechanism 31. When the tubes 41 are conveyed to the designated position, the third lifting cylinder 341 of the material blocking mechanism 34 starts, driving the material blocking member 342 upward, preventing the tubes 41 from moving further, ensuring that the container containing multiple tubes 41 is directly below the sintering mechanism 311.

[0079] 4. The second motor 2322 of the lifting and transporting mechanism 33 is activated, driving the second screw 332 to rotate through the reducer, thereby driving the support base 333 upward, lifting the tube 41 to the sintering area within the sintering mechanism 31. The heating element is activated, sintering the tube 41 at a high temperature, causing the copper powder to sinter and form a liquid wick.

[0080] 5. After sintering is complete, the heating element turns off, and the second motor 2322 of the lifting and transporting mechanism 33 rotates in the opposite direction, driving the support base 333 downward, thus transporting the tube 41 out of the sintering area. The third lifting cylinder 341 of the material retaining mechanism 34 then drives the retaining member 342 downward, releasing the tube 41. The third motor 331 then continues to operate, and the feed wheel 323 transports the tube 41 out of the sintering mechanism 31, completing the sintering process.

[0081] High-temperature sintering creates a metallurgical bond between the copper powder particles, forming a wick structure with a certain porosity and strength. Through capillary action, the wick replenishes the liquid lost in the evaporation section of the heat pipe due to vaporization from the condensation section, enabling liquid circulation within the heat pipe and continuously transferring heat away from the heat source. This creates a wick structure with excellent capillary and heat transfer properties, improving the heat transfer efficiency of the heat pipe. The precise control and automated operation of the sintering device 3 ensures the stability and consistency of the sintering process, enhancing product quality and production efficiency.

[0082] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
