Description

Technical Field

[0001] The invention relates to the technical field of diamond heat sinks, and in particular to a diamond heat sink and a preparation method thereof. Background Art

[0002] Synthetic diamond materials are advantageously used in heat sinks because they have extremely high thermal conductivity, allowing efficient diffusion of heat from hot spots and efficient transfer of heat from heat generating components to a fluid coolant. Synthetic diamond materials are also advantageous in these applications because they have a low coefficient of thermal expansion and high rigidity, so they are mechanically and geometrically stable and experience low thermal deformation even when exposed to large temperature changes.

[0003] Most of the existing diamond heat sinks use heat sinks for heat dissipation. One side of the heat sink is fixed on the heating component, and the gas flow or liquid flow on the other side of the heat sink is used to achieve the purpose of heat dissipation. However, since the heat sinks of the existing diamond heat sinks are mostly thin discs, the heat sinks are easily broken due to vibration during use, and the gas or liquid at the heat dissipation end of the existing diamond heat sink can only flow through the surface of the heat sink, resulting in a small contact area with the heat sink, affecting the overall heat dissipation efficiency of the heat sink. Therefore, it is necessary to design a diamond heat sink and a preparation method thereof to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a diamond heat sink and a preparation method thereof.

[0038] The above-mentioned processing equipment includes a workbench 7, a support frame 8 is installed on the upper end of the workbench 7, and a plurality of arc blocks are arranged on the inner top of the support frame 8. The inner walls on the left and right sides of the support frame 8 are connected to a screw rod 9 for rotation together. The threaded layer on the screw rod 9 is a reciprocating threaded layer. When the screw rod 9 rotates, the moving block 10 can move left and right. A first motor 29 is installed on the left side of the support frame 8.

In the initial state, the upper end of the slider 35 contacts the inner top of the support frame 8. The slider 35 is elastically connected to the adjacent side of the rectangular block by a third spring 39. A drilling assembly is provided on the slider 35.

[0039] Among them, the drilling assembly includes multiple rotating shafts installed on the I-shaped block, and the multiple rotating shafts are connected through the second transmission assembly 38. The second transmission assembly 38 includes second sprockets arranged on multiple rotating shafts, and the multiple second sprockets are connected through the second chain transmission. In order to ensure the stability of the transmission of the second transmission assembly 38, multiple auxiliary transmission wheels can be set. A second motor 37 is installed on the I-shaped block, and the end of the output shaft of the second motor 37 is fixedly connected to the rotating shaft located in the middle. The lower ends of the three rotating shafts are fixedly connected to the cylinder 12, and the milling cutters 13 are slidably connected in the multiple cylinders 12.

[0040] Among them, it also includes an air blowing cleaning component, which includes a rectangular box 16 arranged on the right side of the support frame 8, and the left inner wall of the rectangular box 16 is rotatably connected to a thin rod 17, and a fan 18 is fixedly connected to the thin rod 17. The upper end of the workbench 7 is fixedly connected to a hollow plate 32, and the left side of the hollow plate 32 is connected to a plurality of nozzles 33. The hollow plate 32 is connected to the left side space of the rectangular box 16 through an air duct 31. A gear box 11 is installed on the right side of the support frame 8, and the right side of the screw rod 9 is fixedly connected to the input shaft of the gear box 11. The output shaft of the gear box 11 is connected to the thin rod 17 through a first transmission component 15. The first transmission component 15 includes a first sprocket arranged on the gear box 11 and the thin rod 17. The two first sprockets are connected through a first chain transmission. The gear box 11 can increase the rotation speed, so that the rotation speed of the fan 18 is faster, thereby generating a large airflow blowing into each groove 6.

[0041] Among them, the lower end of the workbench 7 is fixedly connected to a mounting frame 42, the upper end of the mounting frame 42 is rotatably connected to a vertical rod 43, the workbench 7 is provided with a round mouth, the upper end of the vertical rod 43 is fixedly connected to a rotating table 27, the rotating table 27 is provided with a plurality of slots 28, the upper end of the workbench 7 is provided with a push assembly, the push assembly includes a fixed block 20 arranged above the workbench 7, the rear side of the fixed block 20 is fixedly connected to two pneumatic rods 21, the telescopic ends of the two pneumatic rods 21 are commonly fixedly connected to a strip plate 22, the rear side of the strip plate 22 is fixedly connected to a telescopic rod 23, and the two telescopic The telescopic ends of the rod 23 are commonly fixedly connected with a push plate 25, and the rear side of the push plate 25 is fixedly connected with two limit blocks, so that the heat sink 1 cannot be driven to rotate when the rotating table 27 rotates. When the multiple reinforcing ribs 4 enter the slots 28, the multiple limit blocks will be located above the heat sink 1, so that the heat sink 1 can rotate with the rotating table 27. The push plate 25 and the adjacent side of the strip plate 22 are elastically connected by the first spring 24. The upper end of the workbench 7 is fixedly connected with two lateral baffles 19, and the adjacent sides of the two lateral baffles 19 are commonly fixedly connected with the rear baffle 14.

[0042] The workbench 7 is provided with a strip opening 26 , the lower end of the strip plate 22 is fixedly connected with a fixing rod 40 , a rack 41 is fixedly connected to the fixing rod 40 , and a rotating gear 44 matched with the rack 41 is provided on the vertical rod 43 .

[0043] The functional principle of the present invention can be explained through the following operation mode: when processing the radiator, the heat sink 1 equipped with a plurality of reinforcing ribs 4 is placed on the workbench 7, and the pneumatic rods 21 are started. The two pneumatic rods 21 are stretched to drive the strip plate 22 to move backward, and the heat sink 1 is pushed backward to the rotating table 27 through the push plate 25. When the heat sink 1 contacts the rear baffle 14, the rack 41 will mesh with the rotating gear 44. The continued stretching of the pneumatic rods 21 will cause the strip plate 22 to drive the rack 41 to move backward, and the push plate 25 and the heat sink 1 will no longer move, and the first spring 24 will be compressed;

[0044] When the rack 41 moves backward, the vertical rod 43 is driven to rotate by rotating the gear 44, so that the rotating platform 27 rotates. Due to the obstruction of the limit block on the push plate 25, the heat sink 1 will not rotate at this time. During the rotation of the rotating platform 27, when the multiple slots 28 rotate to the bottom of the reinforcing rib 4, the heat sink 1 will fall under the action of gravity, and the multiple reinforcing ribs 4 will enter the slots 28. At this time, the continued rotation of the rotating platform 27 will drive the heat sink 1 to rotate;

[0045] It is worth mentioning that when the heat sink 1 is placed on the rotating table 27, the initial positions of the three milling cutters 13 are not located directly above the heat sink 1, so that the milling cutters 13 will not affect the movement of the heat sink 1. When the plurality of reinforcing ribs 4 fall into the slots 28, the upper surface of the heat sink 1 and the lower ends of the plurality of milling cutters 13 are on the same horizontal plane.

[0046] After the heat sink 1 is placed, the first motor 29 and the second motor 37 are controlled to operate. The second motor 37 drives the plurality of milling cutters 13 to rotate through the second transmission assembly 38. The operation of the first motor 29 drives the screw rod 9 to rotate, so that the moving block 10 drives the plurality of milling cutters 13 to move left and right. During the movement of the moving block 10, when the slider 35 moves under the arc block, the slider 35 moves along the arc block, so that the milling cutter 13 moves in an arc shape. Due to the elastic effect of the second spring 34 and the third spring 39, the milling cutter 13 is always tightly pressed on the heat sink 1, so that three grooves 6 of the same size are opened on the heat sink 1.

[0047] During the grooving process, the rotation of the screw 9 will drive the input shaft of the gear box 11 to rotate, and the acceleration of the gear box 11 will accelerate the output shaft of the gear box 11, and the thin rod 17 will be driven to rotate through the first transmission component 15, thereby rotating the fan 18. The fan 18 will suck the outside air into the rectangular box 16, and then enter the hollow plate 32 through the air duct 31, and then spray it out through multiple nozzles 33, so as to blow out the debris in the groove 6, so that during the processing, the staff can observe the situation in the groove 6 more clearly to ensure the processing quality of the heat sink 1.

[0048] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
