Description

Technical Field

[0001] This invention relates to the field of heat sink fin processing, specifically to a welding processing equipment and welding method for heat sink fins and a base plate. Background Technology

[0002] Heat sink fins are the core component of forced convection heat dissipation structures. Their function is to increase the heat dissipation area and accelerate the transfer of heat from the base plate to the air (or coolant). The main material is high thermal conductivity aluminum alloy, which takes into account both lightweight and processability. Copper fins have better thermal conductivity but are more expensive and are mostly used in miniature precision heat sinks. Stainless steel fins are suitable for corrosive environments and are widely used in high heat flux density scenarios such as motors, industrial control equipment, new energy vehicle inverters, and server CPUs.

[0003] The welding of heat dissipation fins to the base plate is a core process in the manufacturing of high heat flux density heat dissipation structures, such as server heat sinks and heat sinks for motor controllers in new energy vehicles. The welding quality directly determines the heat dissipation efficiency, structural strength, and service life. Before welding, the oxide film and oil stains on the contact surface must be thoroughly removed, and the assembly gap must be strictly controlled. During welding, the temperature, vacuum degree, or stirring head parameters must be precisely adjusted to prevent defects such as porosity, incomplete welding, and fin collapse. After welding, thermal resistance testing, ultrasonic testing, and cold and hot cycle testing are conducted to ensure the joint quality and heat dissipation performance.

[0004] In existing technologies, there is no air convection in vacuum brazing furnaces, and heat transfer is mainly through thermal radiation. This results in high-temperature and low-temperature zones within the furnace chamber. The area near the heating element radiates heat strongly and its temperature rises rapidly, while the area farther from the heating element receives less heat and its temperature rises slowly, creating a certain temperature difference. The melting, wetting, and flow of the brazing filler metal are entirely temperature-driven. After the brazing filler metal melts in the high-temperature zone, the connection between the heat sink fins and the base plate changes from a solid to a liquid state, significantly reducing the root support strength and making it unable to resist the bending stress generated by thermal expansion. At this point, the fins will tilt and shift towards the lower-temperature side under stress. After welding, the furnace cools down, and the fins and base plate in the high-temperature zone cool down and shrink more, and the cooling rate is faster than in the low-temperature zone, further widening the shrinkage difference. This causes the tilted heat sink fins to be unable to spring back, ultimately resulting in a permanent vertical deviation. After the heat sink fins tilt, the gap between them and the base plate becomes uneven, and the solidification and shrinkage of the brazing filler metal during subsequent cooling will also be uneven, which in turn aggravates weld defects, causing the entire heat sink assembly to be scrapped, or failing to meet usage requirements due to reduced heat dissipation efficiency and insufficient structural strength. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a welding processing device for heat dissipation fins and base plate to solve the technical problems mentioned above in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a welding processing equipment for heat dissipation fins and a base plate, comprising a main body, a conveyor belt, and a gas collection box, wherein the conveyor belt is movably installed inside the main body, and the gas collection box is mounted inside the main body; The bottom plate placement mold and the fin placement mold are movably placed on the upper end of the conveyor belt, and the bottom plate placement mold and the fin placement mold are bolted together. The conveyor belt has multiple sets of reserved holes. Two sets of conveyor rollers are movably installed inside the main body of the equipment, and the two sets of conveyor rollers are connected by a toothed synchronous belt. A drive motor is mounted on one end of the main body of the equipment, and the output end of the drive motor is connected to one set of conveyor rollers. The outer walls of the two sets of conveyor rollers are movably connected to the inner wall of the conveyor belt. The gas collection box is equipped with multiple sets of electric heating rods, and the upper end of the gas collection box is movably connected to the inner wall of the conveyor belt. The main body of the equipment is equipped with a visual inspection device, which is electrically connected to the drive motor.

[0007] By adopting the above technical solution, the problem of uneven heating during the hot welding process between the heat sink fins and the base plate is solved. Multiple sets of heating rods are activated, raising the internal temperature of the gas collection box. The heat energy contacts the base plate through multiple sets of reserved holes, heating the base plate from the bottom. This process avoids uneven heating caused by heat flowing out from one side, preventing the formation of high-temperature and low-temperature zones. It also ensures that the solder is heated and liquefied evenly, preventing the multiple sets of heat sink fins from tilting and improving the hot welding effect between the heat sink fins and the base plate.

[0008] The present invention is further configured such that a hydraulic pump is installed at the upper end of the main body of the equipment, a hydraulic column is installed at the output end of the hydraulic pump, an air collecting plate is installed at one end of the hydraulic column extending into the interior of the main body of the equipment, an installation column is installed at the upper end of the air collecting plate, and a toothed plate is installed at the upper end of the installation column.

[0009] Preferably, the hydraulic pump is started, which drives the hydraulic column to move downward, thereby driving the air collecting plate to move downward, which in turn drives the mounting column to move downward, and then drives the toothed plate to move downward.

[0010] The present invention is further configured such that a transmission shaft is movably installed inside the main body of the device, and a transmission gear is installed at the center end of the transmission shaft, and the transmission gear is meshed with a gear plate.

[0011] Preferably, the toothed plate moves downward and meshes with the transmission gear, causing the transmission gear to rotate, which in turn drives the transmission shaft to rotate.

[0012] The invention is further configured such that multiple sets of movable cylinders are symmetrically installed inside the main body of the device, and toothed synchronous belts are respectively connected between the multiple sets of movable cylinders. Both ends of the transmission shaft are respectively connected to two sets of movable cylinders by toothed synchronous belts. Telescopic columns are movably installed inside the multiple sets of movable cylinders, and the outer walls of the multiple sets of telescopic columns are respectively threaded to the inner walls of the multiple sets of movable cylinders. Limiting plates are symmetrically installed inside the main body of the device, and two sets of limiting plates are respectively connected to one end of the multiple sets of telescopic columns. The inner walls at both ends of the two sets of limiting plates are arc-shaped.

[0013] Preferably, the drive shaft rotates, and its two ends are connected to two sets of movable cylinders via toothed synchronous belts. Thus, two sets of movable cylinders rotate, and multiple sets of movable cylinders are connected to each other via toothed synchronous belts, thus multiple sets of movable cylinders rotate. The inner walls of multiple sets of movable cylinders are threadedly connected to the outer walls of multiple sets of telescopic columns, thus multiple sets of telescopic columns are displaced, thereby driving two sets of limiting plates to move. The arc-shaped design of the inner walls at both ends of the two sets of limiting plates improves the clamping effect of the mold placed on the base plate.

[0014] The present invention is further configured such that multiple sets of air outlet plates are installed at the bottom end of the air collecting plate, and pressure plates are movably installed between the multiple sets of air outlet plates, and multiple sets of springs are provided between the multiple sets of pressure plates and the air collecting plate.

[0015] Preferably, the air collecting plate moves downward, causing multiple sets of air venting plates and multiple sets of pressure plates to move downward. One end of each set of air venting plates moves into the gap between multiple sets of heat dissipation fins. Then, the multiple sets of pressure plates move to the upper end of the multiple sets of heat dissipation fins. Multiple sets of springs exert thrust on the multiple sets of pressure plates, causing the multiple sets of pressure plates to press the multiple sets of heat dissipation fins together.

[0016] The present invention is further configured such that an air pump is provided inside the main body of the device, and multiple sets of first air outlet pipes are installed at the air outlet end of the air pump, and one end of each set of first air outlet pipes is connected to an air collection box.

[0017] Preferably, the air pump is started, causing airflow to enter the air collection box through multiple sets of first air outlet pipes.

[0018] The present invention is further configured such that multiple sets of second air outlet pipes are symmetrically installed on the outer wall of the air collection box, and one end of each set of second air outlet pipes is connected to the air collection plate, and each set of second air outlet pipes is a corrugated flexible hose.

[0019] Preferably, after the airflow is heated inside the air collection box, part of the airflow enters the air collection plate through multiple sets of second air outlet pipes, and the air collection plate diverts the airflow to the interior of multiple sets of air outlet plates.

[0020] The present invention is further configured such that an air suction plate is installed inside the main body of the device, and the air suction plate is located on one side of the air collection plate, and an air suction pipe is provided between the air suction plate and the air pump.

[0021] Preferably, the airflow enters the air pump through the air intake plate and the air intake pipe, and the air intake plate absorbs part of the hot airflow flowing to the lower part of the air intake plate.

[0022] A welding equipment and welding method for heat dissipation fins and a base plate, comprising the following steps: S1: Installation and fixing of heat dissipation fins and base plate: Multiple sets of heat dissipation fins are placed inside the fin placement mold, the base plate is placed inside the base plate placement mold, and the base plate placement mold and the fin placement mold are fixedly connected by bolts. S2: Base plate placement mold limiting and fixing: Two sets of limiting plates are displaced, and the two sets of limiting plates cooperate to clamp and fix the base plate placement mold; S3: Heat dissipation fin limit and fixation: One end of multiple sets of air outlet plates moves into the gap between multiple sets of heat dissipation fins, and multiple sets of pressure plates move to the upper end of multiple sets of heat dissipation fins, so that multiple sets of pressure plates press multiple sets of heat dissipation fins together, and the outer wall of multiple sets of air outlet plates and multiple sets of pressure plates cooperate to limit the multiple sets of heat dissipation fins. S4: Solder liquefaction thermal welding: Multiple sets of heating rods raise the internal temperature of the gas collection box, heat the base plate from the bottom end, and the base plate undergoes a heating operation, causing the solder to liquefy. After the solder liquefies, multiple sets of heat dissipation fins and the base plate are thermally welded together. S5: Solder solution encapsulates the welding end between the heat sink fins and the base plate: The air collection plate diverts the hot airflow to the interior of multiple sets of air outlet plates, which then discharge the hot airflow. The discharged hot airflow blows to the connection end between the multiple sets of heat sink fins and the base plate, causing the solder solution flowing between the multiple sets of heat sink fins and the base plate to be blown, so that the solder solution adheres to the outer area of ​​the connection end between the multiple sets of heat sink fins and the base plate, forming an encapsulation.

[0023] In summary, the present invention has the following main beneficial effects: This invention solves the problem of uneven heating during the hot welding of heat dissipation fins and base plate by incorporating a conveyor belt, pre-drilled holes, a gas collection box, and heating rods. Multiple sets of heating rods are activated, raising the internal temperature of the gas collection box. Heat energy contacts the base plate through the pre-drilled holes, heating the base plate from the bottom. This process avoids uneven heating caused by heat flowing out from one side, preventing the formation of high-temperature and low-temperature zones. It ensures uniform heating and liquefaction of the solder, prevents the heat dissipation fins from tilting, and improves the hot welding effect between the heat dissipation fins and base plate.

[0024] This invention features an air collecting plate, an air venting plate, and multiple pressure plates. The air venting plates and pressure plates move downwards, with one end of each air venting plate positioned within the gaps between multiple heat dissipation fins, preventing the fins from tilting. Then, the pressure plates move to the top of the heat dissipation fins, and multiple springs exert thrust on the pressure plates, pressing them together to further prevent tilting. The air collecting plate diverts hot airflow into the air venting plates, which then expel the hot airflow. The expelled hot airflow blows to the connection point between the heat dissipation fins and the base plate, agitating the solder molten metal flowing between them. This causes the solder molten metal to adhere to the outer perimeter of the connection point, forming a wrapping effect and further improving the welding performance between the heat dissipation fins and the base plate.

[0028] The embodiments of the present invention will now be described.

[0029] A welding equipment and welding method for heat dissipation fins and a base plate; please refer to [link to relevant documentation]. Figure 1 - Figure 8 It includes a main body 1, a conveyor belt 4 and a gas collection box 23. The conveyor belt 4 is movably installed inside the main body 1, and the gas collection box 23 is installed inside the main body 1. A base plate placement mold 6 and a fin placement mold 7 are movably placed on the upper end of the conveyor belt 4, and the base plate placement mold 6 and the fin placement mold 7 are connected by bolts. Multiple sets of heat dissipation fins are placed inside the fin placement mold 7, and then the base plate is placed inside the base plate placement mold 6. The base plate placement mold 6 and the fin placement mold 7 are fixedly connected by bolts. The conveyor belt 4 has multiple sets of reserved holes 5. Two sets of conveyor rollers 3 are movably installed inside the main body 1 of the equipment, and the two sets of conveyor rollers 3 are connected by a toothed synchronous belt. A drive motor 2 is mounted on one end of the main body 1 of the equipment, and the output end of the drive motor 2 is connected to a set of conveyor rollers 3. The outer walls of the two sets of conveyor rollers 3 are movably connected to the inner wall of the conveyor belt 4. When the drive motor 2 is started, the drive motor 2 drives the set of conveyor rollers 3 to rotate. The two sets of conveyor rollers 3 are connected by a toothed synchronous belt, so the two sets of conveyor rollers 3 rotate synchronously, thereby driving the conveyor belt 4 to run, and thus driving the base plate and multiple sets of heat dissipation fins to move. Multiple sets of electric heating rods 24 are installed inside the gas collection box 23, and the upper end of the gas collection box 23 is movably connected to the inner wall of the conveyor belt 4. The multiple sets of electric heating rods 24 raise the internal temperature of the gas collection box 23 and heat the bottom plate from the bottom end. A visual inspection device is installed inside the main body 1 of the equipment, and the visual inspection device is electrically connected to the drive motor 2.

[0030] Please see Figure 2 - Figure 8 A hydraulic pump 8 is installed on the upper end of the main body 1 of the equipment. A hydraulic column 9 is installed at the output end of the hydraulic pump 8. A gas collecting plate 10 is installed at one end of the hydraulic column 9 extending into the interior of the main body 1 of the equipment. An installation column 11 is installed on the upper end of the gas collecting plate 10. A toothed plate 12 is installed on the upper end of the installation column 11. When the hydraulic pump 8 is started, it drives the hydraulic column 9 to move downward, thereby driving the gas collecting plate 10 to move downward, which in turn drives the installation column 11 to move downward, and then drives the toothed plate 12 to move downward.

[0031] Please see Figure 5 - Figure 6The main body 1 of the equipment has a drive shaft 13 installed inside. A drive gear 14 is installed at the center end of the drive shaft 13 and is meshed with a toothed plate 12. The toothed plate 12 moves downward and meshes with the drive gear 14, so the drive gear 14 rotates, thereby driving the drive shaft 13 to rotate.

[0032] Please see Figure 5 - Figure 6 The main body 1 of the equipment has multiple sets of movable cylinders 15 symmetrically installed inside, and each set of movable cylinders 15 is connected to the other sets by toothed synchronous belts. The two ends of the drive shaft 13 are each connected to two sets of movable cylinders 15 by toothed synchronous belts. Each set of movable cylinders 15 has a telescopic column 16 movably installed inside, and the outer walls of the telescopic columns 16 are threaded to the inner walls of the movable cylinders 15. The main body 1 of the equipment has limit plates 17 symmetrically installed inside, and two sets of limit plates 17 are each connected to one end of one set of telescopic columns 16. The inner walls of both ends of the two sets of limit plates 17 are arc-shaped. The transmission shaft 13 is configured to rotate, and its two ends are connected to two sets of movable cylinders 15 via toothed synchronous belts. Thus, two sets of movable cylinders 15 rotate, and multiple sets of movable cylinders 15 are connected to each other via toothed synchronous belts, thus multiple sets of movable cylinders 15 rotate. The inner walls of multiple sets of movable cylinders 15 are threadedly connected to the outer walls of multiple sets of telescopic columns 16, thus multiple sets of telescopic columns 16 are displaced, thereby driving the two sets of limiting plates 17 to move. The arc-shaped design of the inner walls at both ends of the two sets of limiting plates 17 improves the clamping effect of the mold 6 placed on the base plate.

[0033] Please see Figure 5 - Figure 8 Multiple sets of air outlet plates 18 are installed at the bottom of the air collection plate 10. Pressure plates 20 are movably installed between the multiple sets of air outlet plates 18. Multiple sets of pressure plates 20 are connected to the air collection plate 10 by multiple sets of springs 19. When the air collection plate 10 moves downward, it drives the multiple sets of air outlet plates 18 and multiple sets of pressure plates 29 to move downward. One end of each set of air outlet plates 18 moves into the gap between multiple sets of heat dissipation fins. Then, the multiple sets of pressure plates 20 move to the upper end of the multiple sets of heat dissipation fins. The multiple sets of springs 19 exert a pushing force on the multiple sets of pressure plates 20, so that the multiple sets of pressure plates 20 press the multiple sets of heat dissipation fins together.

[0034] Please see Figure 9 - Figure 10 The main body 1 of the equipment is equipped with an air pump 21. Multiple sets of first air outlet pipes 22 are installed at the air outlet end of the air pump 21, and one end of each set of first air outlet pipes 22 is connected to the air collection box 23. When the air pump 21 is started, the airflow enters the air collection box 23 through the multiple sets of first air outlet pipes 22.

[0035] Please see Figure 5 - Figure 10Multiple sets of second air outlet pipes 25 are symmetrically installed on the outer wall of the air collection box 23, and one end of each set of second air outlet pipes 25 is connected to the air collection plate 10. All sets of second air outlet pipes 25 are corrugated hoses. After the airflow is heated inside the air collection box 23, part of the airflow enters the air collection plate 10 through the multiple sets of second air outlet pipes 25. The air collection plate 10 diverts the airflow to the interior of the multiple sets of air outlet plates 18.

[0036] Please see Figure 2 - Figure 10 The main body of the equipment is equipped with an air suction plate 27, which is located on one side of the air collection plate 10. The air suction plate 27 is connected to the air pump 21 by an air suction pipe 26. The airflow enters the air pump 21 through the air suction plate 27 and the air suction pipe 26. The air suction plate 27 absorbs part of the hot airflow flowing to the lower part of the air suction plate 27.

[0037] The working principle of this invention is as follows: When the operator uses the equipment to weld the heat dissipation fins to the base plate, the operator puts multiple sets of heat dissipation fins into the fin placement mold 7, then puts the base plate into the base plate placement mold 6, and fixes the base plate placement mold 6 and the fin placement mold 7 together with bolts. Then the base plate placement mold 6 and the fin placement mold 7 are placed in the center area of ​​one end of the conveyor belt 4. After the base plate placement mold 6 and the fin placement mold 7 are placed, the operator starts the drive motor 2. The drive motor 2 drives a set of conveyor rollers 3 to rotate. The two sets of conveyor rollers 3 are connected by a toothed synchronous belt, so the two sets of conveyor rollers 3 rotate synchronously, thereby driving the conveyor belt 4 to run, and then driving the base plate and multiple sets of heat dissipation fins to move. The vision detection device inside the main body 1 detects the movement of the base plate and multiple sets of heat dissipation fins. When the base plate and multiple sets of heat dissipation fins move between the two sets of limit plates 17, the vision detection device controls the drive motor 2 to shut down. When the drive motor 2 is turned off, the hydraulic pump 8 starts, causing the hydraulic column 9 to move downward, which in turn causes the air collecting plate 10 to move downward, which in turn causes the mounting column 11 to move downward, and then causes the toothed plate 12 to move downward. The toothed plate 12 meshes with the transmission gear 14, so the transmission gear 14 rotates, which in turn causes the transmission shaft 13 to rotate. The two ends of the transmission shaft 13 are respectively connected to two sets of movable cylinders 15 through toothed synchronous belts, so two sets of movable cylinders 15 rotate. Multiple sets of movable cylinders 15 are respectively connected to each other through toothed synchronous belts, so multiple sets of movable cylinders 15 rotate. The inner walls of multiple sets of movable cylinders 15 are respectively threaded to the outer walls of multiple sets of telescopic columns 16, so multiple sets of telescopic columns 16 move, which in turn causes two sets of limiting plates 17 to move. The two sets of limiting plates 17 cooperate to clamp and fix the base plate placing mold 6. The air collection plate 10 continues to move downward, causing multiple sets of air outlet plates 18 and multiple sets of pressure plates 29 to move downward. One end of each set of air outlet plates 18 moves into the gap between multiple sets of heat dissipation fins. Then, multiple sets of pressure plates 20 move to the upper end of multiple sets of heat dissipation fins. Multiple sets of springs 19 exert a pushing force on multiple sets of pressure plates 20, causing multiple sets of pressure plates 20 to press together multiple sets of heat dissipation fins. The outer walls of multiple sets of air outlet plates 18 and multiple sets of pressure plates 20 cooperate to limit the multiple sets of heat dissipation fins. After the base plate and multiple sets of heat dissipation fins are positioned, the air pump 21 and multiple sets of electric heating rods 24 are activated. The multiple sets of electric heating rods 24 raise the internal temperature of the air collection box 23, heating the base plate from the bottom. The air pump 21 is activated, allowing airflow to enter the air collection box 23 through multiple sets of first air outlet pipes 22. The multiple sets of electric heating rods 24 heat the airflow. The heated airflow is blown directly to the bottom of the base plate through multiple sets of reserved holes 5, further improving the heating effect at the bottom of the base plate and heating the base plate to liquefy the brazing filler metal. After the brazing filler metal liquefies, multiple sets of springs 19 push the multiple sets of heat dissipation fins, ensuring that the bottom of the multiple sets of heat dissipation fins are in contact with the base plate. After the airflow heats up inside the air collection box 23, part of the airflow enters the air collection plate 10 through multiple sets of second air outlet pipes 25. The air collection plate 10 diverts the airflow to multiple sets of air outlet plates 18, which then discharge the airflow. The discharged airflow blows to the connection end between the multiple sets of heat dissipation fins and the base plate, causing the solder solution flowing between the multiple sets of heat dissipation fins and the base plate to be blown, so that the solder solution adheres to the outer area of ​​the connection end between the multiple sets of heat dissipation fins and the base plate, forming a wrapping shape, which further improves the welding effect between the multiple sets of heat dissipation fins and the base plate. When the air pump 21 is started, the airflow enters the air pump 21 through the air intake plate 27 and the air intake pipe 26. The air intake plate 27 absorbs part of the hot airflow flowing to the lower part of the air intake plate 27, preventing the hot airflow from flowing out from one end of the main body of the equipment 1 and causing harm to the staff.

The welding equipment for heat dissipation fins and base plate according to claim 7, characterized in that: The main body of the equipment is equipped with an air suction plate (27), which is located on one side of the air collection plate (10). The air suction plate (27) is connected to the air pump (21) by an air suction pipe (26).

9. A welding processing equipment and welding method for heat dissipation fins and a base plate, characterized in that... The process of using any one of claims 1-8 includes the following steps: S1: Heat dissipation fins and base plate installation and fixing: Multiple heat dissipation fins are placed inside the fin placement mold (7), and the base plate is placed inside the base plate placement mold (6). The base plate placement mold (6) and the fin placement mold (7) are fixedly connected by bolts. S2: Base plate placement mold (6) limit and fixation: Two sets of limit plates (17) are displaced, and the two sets of limit plates (17) cooperate to clamp and fix the base plate placement mold (6); S3: Heat dissipation fins are fixed and positioned: one end of each of the multiple sets of air outlet plates (18) moves into the gap between the multiple sets of heat dissipation fins, and the multiple sets of pressure plates (20) move to the upper end of the multiple sets of heat dissipation fins, so that the multiple sets of pressure plates (20) press the multiple sets of heat dissipation fins together. The outer wall of the multiple sets of air outlet plates (18) and the multiple sets of pressure plates (20) cooperate to limit the multiple sets of heat dissipation fins. S4: Solder liquefaction heat welding: Multiple sets of heating rods (24) raise the internal temperature of the gas collection box (23), heat the bottom plate from the bottom end, and the bottom plate is heated to make the solder liquefy. After the solder liquefies, multiple sets of heat dissipation fins and the bottom plate are heat welded together. S5: The solder solution wraps around the welding end of the heat dissipation fins and the base plate: The gas collection plate (10) diverts the hot air flow to the interior of the multiple sets of gas outlet plates (18), and the multiple sets of gas outlet plates (18) discharge the hot air flow. The discharged hot air flow blows to the connection end of the multiple sets of heat dissipation fins and the base plate, and blows the solder solution flowing out between the multiple sets of heat dissipation fins and the base plate, so that the solder solution adheres to the outer area of ​​the connection end of the multiple sets of heat dissipation fins and the base plate, forming a wrapping shape.
