Description

Technical Field

[0001] The present invention belongs to the technical field of radiator processing, and particularly relates to a liquid-cooled radiator and its processing technology. Background Art

[0002] With the continuous increase of the CPU power and the gradual reduction of the server volume, the requirements for the volume, fin height, thinness, and fin pitch density of the shovel-tooth radiator are getting higher and higher. The general water-cooled radiator process is CNC rough machining, shovel-tooth machining, CNC finish machining, cleaning, and packaging. Currently, the limit fin thickness of the machined shovel-tooth is greater than 0.06 mm, and the fin pitch is greater than 0.08 mm. However, for CNC machining, only when the fin thickness is greater than 0.6 mm and the fin pitch is greater than 1 mm can the fin height difference and special-shaped avoidance be processed. The reason is that when the fin pitch is less than 1 mm, the CNC cutter will mill off at least 2 fins when cutting, and there are requirements for the number of fins, that is, plus or minus 1 fin. When the fin is required to have a thickness less than 0.8 mm and a height greater than 20 mm, as soon as the CNC milling cutter processes the fin, the cutting edge will be bent or the teeth will be damaged, and the product will be defective. The qualified rate of processing higher than the above standards is extremely low. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] Embodiment 1: As Figures 1 to 7 shown, a liquid-cooled radiator includes a heat-conducting plate 1. A shovel tooth 2 is fixedly connected to the bottom of the heat-conducting plate 1. An installation hole 3 is opened at the top of the heat-conducting plate 1. An installation plate 4 is fixedly connected to the upper part inside the heat-conducting plate 1. A plurality of installation openings 5 are opened at the top of the installation plate 4. A heat-dissipating plate 6 is fixedly connected to the lower part inside the heat-conducting plate 1. A heat-conducting device 7 is arranged inside the heat-dissipating plate 6; after processing, when the user fixes the device through the installation hole 3, the direction of the shovel tooth 2 faces the horizontal direction. During use, the heat generated by the device is first transferred to the heat-conducting sheet below through the heat-conducting plate 1, and then transferred to the heat-dissipating plate 6 below. Through the heat-conducting device 7 inside the heat-dissipating plate 6, the loop cooling groove 602 cools the heat-conducting plate 1 more efficiently, and then through the heat-dissipating component 8, the heat is better transferred to the shovel tooth 2. Among them, the installation opening 5 is used for installing the heat-conducting sheet. The heat-conducting sheet mainly conducts the temperature generated by the device, so that the coolant can dissipate heat from the heat-conducting sheet well, thereby dissipating heat from the device; as Figures 2 to 4 shown, a water inlet groove 601 and a water outlet groove 603 are opened at the top of the heat-dissipating plate 6. A plurality of loop cooling grooves 602 are opened at the top of the heat-dissipating plate 6 between the water inlet groove 601 and the water outlet groove 603. A first water inlet pipe 604 is fixedly connected to the rear side of the heat-dissipating plate 6 at the water inlet groove 601. A first water outlet pipe 605 is fixedly connected to the rear side of the heat-dissipating plate 6 at the water outlet groove 603; loop cooling grooves 602 are arranged directly below the heat-conducting sheets. The coolant enters the water inlet groove 601 from the first water inlet pipe 604, and then is distributed into a plurality of loop cooling grooves 602 to accurately cool the heat-conducting sheets. When the coolant moves in the loop cooling grooves 602, it will continuously heat up, so that when it reaches the next heat-conducting sheet, the cooling effect is not good, and the heat-conducting device 7 is needed to assist in cooling, so that the cooling effect is better. At the same time, the radius dimensions of the water inlet groove 601 and the water outlet groove 603 are larger than the radius dimensions of the loop cooling grooves 602.

[0038] As Figures 2 to 5As shown in the figure, the heat conduction device 7 includes a water storage chamber 701. A baffle 702 is fixedly connected to the right side of the water storage chamber 701. A water outlet 703 is formed through the surface of the baffle 702. A downstream port 704 is formed on the left side of the heat dissipation plate 6. The downstream port 704 is communicated with the water storage chamber 701. A heat dissipation component 8 is fixedly connected to the bottom inside the heat dissipation plate 6. The water storage chamber 701 is filled with a coolant through a second water inlet pipe 9, and the coolant is continuously added into the water storage chamber 701. Under the action of the baffle 702, the added coolant is continuously pushed upward from the bottom of the device, so that the coolant inside continuously flows, absorbs the temperature of the upper return cooling tank 602, enables the return cooling tank 602 to absorb the temperature of the heat conduction fin more efficiently, cools the device, and the heat absorbed inside the water storage chamber 701 moves to the upper part of the device along with the flow of the coolant and falls through the downstream port 704.

[0039] As Figures 6 to 7 shown, the heat dissipation component 8 includes a falling tank 801. A plurality of fixing rods 802 are fixedly connected to the inner wall of the falling tank 801. A rotating plate 803 is rotatably connected to the surface of the fixing rod 802. Two springs 804 are fixedly connected to the right side of the rotating plate 803. The other ends of the springs 804 are fixedly connected to the surface of the falling tank 801. A plurality of water storage devices 11 are fixedly connected to the inside of the rotating plate 803. Inside the falling tank 801, the coolant falling from the upper part will flow above the rotating plate 803. Under the action of the liquid downward pressure and the water blocking plate 805, when the rotating plate 803 accumulates a certain liquid weight, it will rotate. While the water flows down, the spring 804 will bounce the rotating plate 803 back, so that the liquid disperses heat and volatilizes better. At the same time, there are a plurality of rotating plates 803 above the rotating plate 803. When the scattered liquid continues to fall, this behavior will be repeated, so that the heat can be dissipated better and dissipated by the shoveling teeth 2 beside.

[0040] As Figures 6 to 10As shown in the figure, the water storage device 11 includes a water storage tank 1101. On the left side of the side wall of the water storage tank 1101, four connecting rods 1102 are fixedly connected. The four connecting rods 1102 are fixedly connected to the same limiting rod 1103. On the right side surface of the limiting rod 1103, a plurality of water dispersing plates 1104 are rotatably connected. On the side wall of the water dispersing plate 1104, a driving rod 1105 is fixedly connected. On one side surface of the driving rod 1105, a driving ring 1106 is fixedly connected. On the right side of the inner wall of the water storage tank 1101, a rotating ring 1107 is slidably connected. On the inner wall of the rotating ring 1107, a plurality of linkage rods 1108 are fixedly connected. On the right side of the rotating ring 1107, a rotating opening 1109 is formed. At the bottom of the side wall of the rotating opening 1109, an elastic rope 1110 is fixedly connected. At the bottom of the inner wall of the falling groove 801, a water dispersing pipe 1111 is fixedly connected. On the right side of the water dispersing pipe 1111, a water dispersing opening 1112 is formed. On one side of the water dispersing pipe 1111, a plurality of pushing rods 1113 are fixedly connected; the water blocking plate 805 on the rotating plate 803 and the water storage device 11 will intercept the water flow, so that the liquid will stay inside the rotating plate 803 and the water storage tank 1101. When the liquid accumulates to a certain weight, the rotating plate 803 will rotate. At the same time, the angle of the rotating plate 803 after rotation is aligned with the water dispersing pipe 1111. The pushing rods 1113 on the water dispersing pipe 1111 will act on the inclined surface of the rotating opening 1109 to push the rotating ring 1107 to rotate. The rotation of the rotating ring 1107 will drive the linkage rods 1108 to rotate. The rotation of the linkage rods 1108 will drive the driving ring 1106 to deflect with the driving rod 1105 as the center, and then drive the water dispersing plate 1104 to rotate, so that the liquid can flow down into the water dispersing pipe 1111 below. The liquid will flow out from the water dispersing opening 1112 and flow along the falling groove 801, so that the heat can be better conducted by the shovel teeth 2 and dissipated. When the liquid flows down, the spring 804 will bounce the rotating plate 803 back, and the elastic rope 1110 will pull the rotating ring 1107 back. The water dispersing plate 1104 will rotate in the opposite direction to close the bottom of the water storage tank 1101. This process can make the liquid stay in the falling groove 801 for a longer time, so that the heat of the liquid can be better volatilized.

[0041] As Figures 6 to 7 shown, the falling groove 801 is located at the lower part of the water storage bin 701. On the left side surface of the rotating plate 803, a plurality of water blocking plates 805 are fixedly connected. The rotating plate 803 is slidably connected to the falling groove 801; through the blocking of the coolant by the water blocking plates 805, the accumulation of the liquid can press down the rotating plate 803, and the spring 804 will reset to make the rotating plate 803 vibrate, break up the liquid, and disperse the liquid, so that the heat dissipation effect is better.

[0042] As Figures 1 to 5As shown, a second water inlet pipe 9 penetrates through the space on the right side of the baffle 702 and is fixedly connected to the front side of the heat dissipation plate 6. A second water outlet pipe 10 is fixedly connected to the falling groove 801 directly below the second water inlet pipe 9 on the heat dissipation plate 6. The second water inlet pipe 9 and the second water outlet pipe 10 are in a straight line, enabling the coolant to flow through a larger area inside and absorb more heat.

[0043] As Figures 3 to 4 shown, the water storage chamber 701 is located above the heat dissipation plate 6. The edge of the water storage chamber 701 is located outside all the circular cooling grooves 602. The edge of the falling groove 801 coincides with the edge of the water storage chamber 701. The size of the water storage chamber 701 is larger than the size of all the circular cooling grooves 602 combined, enabling the coolant inside the water storage chamber 701 to absorb the heat of all the circular coolants.

[0044] As Figures 2 to 3 shown, a plurality of the circular cooling grooves 602 are correspondingly located below a plurality of mounting openings 5. The edge of the mounting opening 5 is located outside the edge of the circular cooling groove 602. By arranging the circular cooling grooves 602 directly below the heat conducting sheets, the heat conducting sheets can be cooled more precisely, achieving rapid heat absorption.

[0045] As Figures 6 to 7 shown, the spring 804 forms a 45-degree angle with both the falling groove 801 and the rotating plate 803. The water storage chamber 701 is always full of water. When the shovel teeth 2 are installed, the direction of the shovel teeth 2 is horizontally installed. Through the angle, the coolant can conveniently press the rotating plate 803, and the spring 804 can also rebound the rotating plate 803 faster, causing the rotating plate 803 to vibrate continuously.

[0046] The shovel tooth type liquid cooling radiator can effectively increase the heat dissipation area by adopting the design of shovel tooth shape. This design not only improves the heat dissipation efficiency, but also has higher thermal efficiency, lighter weight and smaller volume. Therefore, it has been widely used in the fields of aviation, aerospace, automotive, electronics, etc.

[0047] When the current liquid cooling radiator absorbs heat, it mainly absorbs heat from the equipment through the heat conducting sheets in the mounting openings, and then the coolant absorbs the heat of the heat conducting sheets for heat dissipation. However, when the coolant flows, it continuously absorbs heat from the heat conducting sheets. After rapid heat absorption in the early stage, the coolant flowing into the heat conducting sheets in other places cannot absorb heat well, resulting in the subsequent equipment overheating and not being processed, remaining in a continuously overheated state, which causes great damage to the equipment.

[0048] Working principle of the present invention: First, the user places the metal to be grooved 2 into a CNC machine for machining with a milling cutter to machine the grooved teeth 2. Then, the internal filling technology is adopted to fill the grooved product, making the whole product form an integral body. The combined strength and hardness of all the tooth pieces meet the requirements of the sheet material. Then, it is put into CNC machining. After machining, the filling is removed to obtain the qualified size. Then, the grooved teeth 2 are fixed downward, and the machined heat dissipation plate 6, mounting plate 4, and heat conduction plate 1 are welded in sequence. After welding the heat dissipation plate 6, a water inlet groove 601, a water outlet groove 603, and a return cooling groove 602 are machined on its top, and the return cooling groove 602 is connected to the water inlet groove 601 and the water outlet groove 603 in a parallel manner. After machining, when the user fixes the device through the mounting hole 3, the direction of the grooved teeth 2 is horizontal. When in use, the heat generated by the device is first transferred to the heat conduction fins below through the heat conduction plate 1. Return cooling grooves 602 are arranged directly below the heat conduction fins. The cooling liquid enters the water inlet groove 601 from the first water inlet pipe 604 and then is shunted into multiple return cooling grooves 602 to accurately cool the heat conduction fins. When the cooling liquid moves in the return cooling groove 602, it will continuously heat up, resulting in a poor cooling effect when reaching the next heat conduction fin. During this period, the cooling liquid can be filled into the water storage bin 701 through the second water inlet pipe 9, and the cooling liquid is continuously added to the water storage bin 701. The added cooling liquid will be continuously pushed upward from the bottom of the device under the action of the baffle 702, making the internal cooling liquid flow continuously, absorbing the temperature of the upper return cooling groove 602, so that the return cooling groove 602 can absorb the temperature of the heat conduction fins more efficiently, cooling the device. The heat absorbed inside the water storage bin 701 moves to the upper part of the device along with the flow of the cooling liquid and falls into the falling groove 801 through the downstream port 704. The cooling liquid falling from the upper part will flow above the rotating plate 803. The water blocking plate 805 and the water storage device 11 on the rotating plate 803 will intercept the water flow, making the liquid stay inside the rotating plate 803 and the water storage tank 1101. When the liquid accumulates to a certain weight, the rotating plate 803 will rotate. At the same time, the angle of the rotating plate 803 after rotation is aligned with the water dispersing pipe 1111. The push rod 1113 on the water dispersing pipe 1111 will act on the inclined plane of the rotating opening 1109, pushing the rotating ring 1107 to rotate. The rotation of the rotating ring 1107 will drive the linkage rod 1108 to rotate. The rotation of the linkage rod 1108 will drive the driving ring 1106 to deflect around the driving rod 1105, thereby driving the water dispersing plate 1104 to rotate, allowing the liquid to flow down into the lower water dispersing pipe 1111. The liquid will then flow out from the water dispersing port 1112 and flow along the falling groove 801, enabling the heat to be better conducted by the grooved teeth 2 and dissipated. When the liquid flows down, the spring 804 will bounce the rotating plate 803 back, and the elastic rope 1110 will pull the rotating ring 1107 back. The water dispersing plate 1104 will rotate in the opposite direction to close the bottom of the water storage tank 1101.This process allows the liquid to stay in the falling trough 801 for a longer time, enabling better evaporation of the heat of the liquid. At the same time, there are multiple upper rotating plates 803 and a water storage device 11 on the rotating plate 803. When the dispersed liquid continues to fall, this behavior will be repeated, allowing the heat to dissipate better and be dissipated by the shovel teeth 2 on one side.

[0049] Embodiment 2: The present invention also provides a processing technology for a liquid-cooled radiator. The above liquid-cooled radiator is processed by the said processing technology, and this processing technology includes the following steps:

[0050] S1. First, fix the metal device and place it in a CNC machine for processing with a milling cutter to machine the shovel teeth 2. Then, fill the inside of the teeth, fill the product with the shoveled teeth, make the whole product form a whole, and then put it into CNC processing. After processing, remove the filling.

[0051] S2. Then fix the device, and after machining the heat dissipation plate 6, weld it to the device.

[0052] S3. Then use a milling cutter to machine the water inlet groove 601, the water outlet groove 603, and the return cooling groove 602, and connect the return cooling groove 602 to the water inlet groove 601 and the water outlet groove 603 in a parallel manner.

[0053] S4. Then weld the mounting plate 4 above and machine the mounting opening 5.

[0054] S5. Finally, weld the heat conduction plate 1 above.

[0055] Please refer to Figure 11 , there are multiple fin pieces 102 provided on the water-cooled shovel tooth radiator 101. A filling gap is formed between two adjacent fin pieces 102, and filling is carried out in the middle of each filling gap to form a filling layer 104, and then machining is carried out using a milling cutter 103.

[0056] The above design mainly lies in that with the continuous increase of CPU power and the gradual reduction of the server volume, the requirements for the volume, fin height, thinness, and fin pitch density of the shovel-tooth radiator are getting higher and higher. The general water-cooled radiator process is CNC rough machining, shovel-tooth machining, CNC finish machining, cleaning, and packaging. Currently, the limit fin thickness of the machined shovel-tooth 2 is greater than 0.06 mm, and the fin pitch is greater than 0.08 mm. However, for CNC machining, only when the fin thickness is greater than 0.6 mm and the fin pitch is greater than 1 mm can the fin height difference and special-shaped avoidance be processed. When the fin pitch is less than 1 mm, the CNC cutter will mill off at least 2 fins, and there are requirements for the number of fins, that is, plus or minus 1 fin. When the fins are required to have a thickness lower than 0.8 mm and a height greater than 20 mm, as soon as the CNC milling cutter processes the fins, the cutting edge will be bent or the teeth will be damaged, and the product will be defective. The processing yield rate for products higher than the above standards is extremely low, the cost is extremely high, and mass production is impossible, which has become a major problem in the industry. In order to meet the current product requirements, the in-tooth filling technology is adopted to fill the shovel teeth well, so that the metal device and the filling form an integral product. The combined strength and hardness of all fins meet the requirements of the sheet material, and then it is put into CNC machining. After machining, the filling is removed, which solves the industry pain points in terms of the cutting volume, processing speed, and finished product yield rate of machining, and the efficiency is increased several times.

[0057] In one embodiment, the above liquid-cooled radiator is processed by the processing technology of the above liquid-cooled radiator.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
