Abstract
Description
Technical Field
[0001] This invention belongs to the field of liquid-cooled server technology, and specifically discloses a toothed cold head and processing equipment. Background Technology
[0002] As a highly efficient heat dissipation solution, the spade-toothed cold block is usually manufactured using a micro-dense spade-tooth process. This process significantly increases the contact area between the cooling water channel and the CPU core through the densely arranged spade-tooth structure, thereby effectively improving the heat conduction efficiency. Traditional cold head manufacturing relies on using copper plates as the base material, processing them one by one into toothed plates using a tooth-shaving machine. This single-plate sequential processing method results in low overall production efficiency. Because the processed toothed plates are usually thin, the gaps between the microchannels formed between the plates are extremely narrow. During processing, metal debris easily clogs the microchannels.
[0003] Therefore, those skilled in the art propose a toothed cold head and processing equipment to solve the problems mentioned above. Summary of the Invention
[0004] In view of this, the technical problem to be solved by the present invention is to provide a tooth-shaving cold head and processing equipment to solve the problem of low processing efficiency of the existing tooth-shaving cold head.
[0005] To achieve the above objectives, the present invention provides a toothed cold head, including a heat exchange plate, wherein the top of the heat exchange plate is provided with heat exchange teeth formed by tooth cutting, and the heat exchange teeth are distributed in a rectangular array.

The inner wall of the recovery chamber has evenly distributed filter holes that communicate with the liquid storage chamber. A pump body is installed inside the liquid storage chamber. The outlet end of the pump body is connected to a connecting pipe. A placement mechanism is installed inside the recovery chamber. A processing mechanism is installed on the surface of the base. The processing mechanism includes a first motor disposed on the surface of the base, a lead screw fixedly connected to the output shaft of the first motor, a mounting block threadedly connected to the surface of the lead screw, a guide rod fixedly connected to the surface of the base, the bottom of the mounting block slidably connected to the surface of the guide rod, and a drive assembly disposed on the surface of the mounting block.
[0007] In the above technical solution, preferably, the drive assembly includes an electric push rod whose output shaft is fixedly connected to the surface of the mounting block and a mounting plate is fixedly connected to it. A fixing block is fixedly connected to the bottom of the mounting plate, and evenly distributed insert teeth are fixedly connected to the bottom of the fixing block.
[0008] In the above technical solution, preferably, the fixing block has a flow guiding cavity inside, the flow guiding cavity has a fixing tube inside, both ends of the fixing tube extend through the fixing block, the diameter of the fixing tube is smaller than the inner diameter of the flow guiding cavity, the bottom of the fixing tube has uniformly distributed drainage holes, one end of the fixing tube is fixedly connected to a support column, the surface of the base is fixedly connected to a guide rod, the surface of the support column and the surface of the guide rod are slidably connected, and the other end of the fixing tube is fixedly connected to the surface of the mounting block.
[0009] In the above technical solution, preferably, the insert tooth has a connecting cavity inside, and the surface of the insert tooth has uniformly distributed drainage grooves that are connected to the connecting cavity. The top of the insert tooth is provided with an outlet pipe that is connected to the connecting cavity, and the other end of the outlet pipe is connected to the guide cavity. The side of the insert tooth near the mounting block has a discharge hole that is connected to the connecting cavity.
[0010] In the above technical solution, preferably, the mounting block is provided with an inlet tube, one end of which is connected to the fixing tube and the other end of which is connected to the connecting tube.
[0011] In the above technical solution, preferably, the placement mechanism includes a second motor disposed inside the base, the output shaft of the second motor passing through the interior of the recovery chamber and fixedly connected to a placement block, the placement block having an installation cavity inside, a vacuum pump disposed inside the installation cavity, a second adsorption cavity located above the installation cavity inside the placement block, the air inlet of the vacuum pump being connected to the second adsorption cavity, a through hole communicating with the outside being opened on the inner wall of the installation cavity, a second diaphragm fixedly connected to the inner wall of the second adsorption cavity, an exhaust pipe disposed inside the placement block, one end of the exhaust pipe being connected to the second adsorption cavity, the other end of the exhaust pipe passing through the placement block, and a solenoid valve disposed inside the exhaust pipe.
[0012] In the above technical solution, preferably, the surface of the placement block is fixedly connected with uniformly distributed placement plates, the top of the placement plates is provided with uniformly distributed first adsorption cavities that are connected to the second adsorption cavity, and the inner wall of the first adsorption cavity is fixedly connected with a first diaphragm.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a toothed cold head, the heat exchange teeth of the toothed cold head form a wider flow channel, which can effectively prevent blockage. The strength of the teeth is much higher than that of the toothed plates, which can prevent deformation, facilitate transportation, and avoid the problem of deformation during transportation of traditional toothed plates. In addition, the wider flow channel is more conducive to internal passivation treatment and cleaning. Furthermore, the design of the heat exchange teeth can be processed by tooth-cutting process, which improves processing efficiency. 2. During the gear shaping process, the cutting fluid is precisely sprayed from the drain hole on the surface of the fixed tube and the guide cavity and connecting cavity inside the gear shaping to the inside of the machined gear groove. This can cool the gear body in real time and directly wash away the chips generated during the machining process. In addition, during the gear shaping reset process, the discharge hole on its side can use the cutting fluid flow to completely flush out the residual chips from the gear groove, effectively avoiding scratches and wear on the machined tooth surface by the chips during reset. This not only improves the tool life, but also significantly improves the final surface finish and yield of the workpiece. 3. By setting up a placement mechanism and utilizing the cooperation of a vacuum pump and an adsorption chamber, the workpiece is stably adsorbed onto the placement plate, ensuring a secure clamping without damaging the workpiece surface. A second motor integrated inside the placement block drives the workpiece and the entire placement mechanism to rotate and position 90°. This allows the processing mechanism to perform linear tooth-setting operations in a single direction, completing the tooth groove processing in two separate, mutually perpendicular directions through precise workpiece rotation. This ultimately results in a highly efficient rectangular array of heat exchange teeth, avoiding complex multi-axis linkages or multiple repeated clamping, simplifying the equipment structure, reducing costs, and effectively minimizing cumulative errors that may arise from multiple clamping operations, ensuring high precision in the tooth array distribution.

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0018] like Figures 1-7 The illustrated toothed cold head includes a heat exchange plate 5, the top of which is provided with heat exchange teeth formed by tooth cutting, and the heat exchange teeth are distributed in a rectangular array.
[0019] The design of the heat exchanger teeth has the following advantages compared to the existing toothed plate method: Wider flow channels can effectively prevent blockages; The strength of the teeth is much higher than that of the toothed plates, which can prevent deformation, facilitate transportation, and avoid the problem of deformation during transportation of traditional toothed plates; Wider flow channels are more conducive to internal passivation treatment and easier cleaning; Furthermore, the heat exchanger teeth can be manufactured using a gear-cutting process, resulting in high production efficiency.
[0020] like Figures 1-7 As shown, a processing device for a toothed cold head includes: The base 1 has a liquid storage chamber 101 inside and a recovery chamber 102 on the top of the base 1. The inner wall of the recovery chamber 102 has evenly distributed filter holes that are connected to the liquid storage chamber 101. The liquid storage chamber 101 is equipped with a pump body 4. The liquid outlet of the pump body 4 is connected to a connecting pipe 401. The recovery chamber 102 is equipped with a placement mechanism 3. The surface of the base 1 is equipped with a processing mechanism 2. The processing mechanism 2 includes a first motor 201 disposed on the surface of the base 1. The output shaft of the first motor 201 is fixedly connected to a lead screw 202. A mounting block 203 is threadedly connected to the surface of the lead screw 202. A guide rod is fixedly connected to the surface of the base 1. The bottom of the mounting block 203 is slidably connected to the surface of the guide rod. A drive assembly 21 is disposed on the surface of the mounting block 203.
[0021] Specifically, by starting the first motor 201, the lead screw 202 can be rotated, thereby moving the mounting block 203 to adjust the position of the drive assembly 21 to process the plate to be processed. The placement mechanism 3 is set up for placing the plate to be processed. The inside of the liquid storage chamber 101 is used to fill the cutting fluid. By starting the pump body 4, the cutting fluid inside the liquid storage chamber 101 can be drawn into the inside of the connecting pipe 401 and introduced into the inside of the processing mechanism 2 for cooling and washing off debris during the processing. The washed debris and cutting fluid can be collected through the recovery chamber 102 and filtered through the filter hole before the cutting fluid is guided back into the liquid storage chamber 101 for reuse.
[0022] like Figures 1-7 As shown, the drive assembly 21 includes an electric push rod 2101 whose output shaft is fixedly connected to the surface of the mounting block 203, and a mounting plate 2102 is fixedly connected to the mounting plate 2102. A fixing block 2105 is fixedly connected to the bottom of the mounting plate 2102, and evenly distributed insert teeth 2107 are fixedly connected to the bottom of the fixing block 2105.
[0023] The fixed block 2105 has a flow guiding cavity 2110 inside, and a fixed tube 2103 is installed inside the flow guiding cavity 2110. Both ends of the fixed tube 2103 extend through the fixed block 2105. The diameter of the fixed tube 2103 is smaller than the inner diameter of the flow guiding cavity 2110. The bottom of the fixed tube 2103 has evenly distributed drainage holes 2111. One end of the fixed tube 2103 is fixedly connected to a support column, and a guide rod is fixedly connected to the surface of the base 1. The surfaces of the support column and the guide rod are slidably connected. The other end of the fixed tube 2103 is fixedly connected to the surface of the mounting block 203.
[0024] The insert tooth 2107 has a connecting cavity 2108 inside, and the surface of the insert tooth 2107 has evenly distributed drainage grooves 2112. The drainage grooves 2112 are connected to the connecting cavity 2108. The top of the insert tooth 2107 is provided with an outlet pipe 2106 connected to the connecting cavity 2108. The other end of the outlet pipe 2106 is connected to the guide cavity 2110. The side of the insert tooth 2107 near the mounting block 203 has a discharge hole 2109 connected to the connecting cavity 2108.
[0025] The mounting block 203 has an inlet tube 2104 inside. One end of the inlet tube 2104 is connected to the fixing tube 2103, and the other end of the inlet tube 2104 is connected to the connecting tube 401.
[0026] By activating the electric push rod 2101, the mounting plate 2102 can be moved, which in turn moves the fixing block 2105 synchronously. The fixing tube 2103 guides the fixing block 2105 during its movement, making it more stable. During the movement of the fixing block 2105, the pick 2107 can move synchronously, and the pick 2107 can cut the placed plate, thus processing the plate. During the processing, by activating the pump body 4, the cutting fluid can be injected into the inlet pipe 2104 through the connecting pipe 401, and then into the fixing tube 2103 through the inlet pipe 2104, and discharged through the drain hole 2111. Thus, during the movement of the fixing tube 2103, the surface of the plate to be processed can be sprayed with cutting fluid, so that the pick 2107 can perform pick processing. Furthermore, because the cutting fluid discharged from the drain hole 2111 of the guide cavity 2110 is partially blocked by the fixing block 2105, it can be injected into the interior of the guide cavity 2110 through the drain hole 2111. It can then be guided into the interior of the connecting cavity 2108 through the outlet pipe 2106, and finally discharged through the drain groove 2112. This allows the groove generated during the gear hobbing process to be sprayed and washed. During the resetting of the gear hobbing 2107, the drain hole 2109 allows the flushed cutting fluid to flush out the internal debris, preventing the debris from causing wear on the groove wall formed by the gear hobbing process during the resetting process.
[0027] like Figures 1-7 As shown, the placement mechanism 3 includes a second motor 301 disposed inside the base 1. The output shaft of the second motor 301 passes through the interior of the recovery chamber 102 and is fixedly connected to a placement block 309. The placement block 309 has an installation cavity inside, and a vacuum pump 302 is disposed inside the installation cavity. A second adsorption chamber 308 located above the installation cavity is disposed inside the placement block 309. The air inlet end of the vacuum pump 302 is connected to the second adsorption chamber 308. The inner wall of the installation cavity has a through hole connected to the outside. A second diaphragm 307 is fixedly connected to the inner wall of the second adsorption chamber 308. An exhaust pipe 303 is disposed inside the placement block 309. One end of the exhaust pipe 303 is connected to the second adsorption chamber 308, and the other end of the exhaust pipe 303 passes through the placement block 309. A solenoid valve is disposed inside the exhaust pipe 303.
[0028] The surface of the placement block 309 is fixedly connected with uniformly distributed placement plates 306. The top of the placement plate 306 is provided with uniformly distributed first adsorption chambers 305 that are connected to the second adsorption chamber 308. The inner wall of the first adsorption chamber 305 is fixedly connected with a first diaphragm 304.
[0029] By activating the vacuum pump 302, the air inside the first adsorption chamber 305 and the second adsorption chamber 308 can be extracted, thereby creating a negative pressure in the first adsorption chamber 308 and the second adsorption chamber 305, which in turn adsorbs the plate. The plate position can be adjusted by driving the placement block 309 to rotate through the second motor 301, and the adjustment angle is 90°. Thus, under the action of the processing mechanism 2, the plate can be processed into a rectangular array of heat exchange teeth.
[0030] Furthermore, when placing the board on top of the placement block 309, it is necessary to refer to... Figure 1 The placement method allows the heat exchange teeth to be machined into the required shape.
[0031] Working principle: After the sheet material is placed and fixed in the placement mechanism 3, the electric push rod 2101 is activated to move the mounting plate 2102. During this process, the fixing block 2105 moves synchronously. The fixing tube 2103 guides the fixing block 2105 during its movement, making its movement more stable. The movement of the fixing block 2105 also drives the pick teeth 2107 to move synchronously, allowing the pick teeth 2107 to perform pick cutting on the placed sheet material, thus achieving the processing of the sheet material. During processing, the pump body 4 is activated to inject cutting fluid through the connecting pipe 401. The fluid enters the inside of the inlet pipe 2104 and is then injected into the fixed pipe 2103 through the inlet pipe 2104, and discharged through the drain hole 2111. As the fixed pipe 2103 moves, the surface of the plate to be processed can be sprayed with cutting fluid to facilitate the hobbing of the gear 2107. Under the action of the pump body 4, the grooves generated during the hobbing process can be sprayed and rinsed. During the resetting process of the hobbing 2107, the discharge hole 2109 allows the flushed cutting fluid to flush out the internal debris, preventing the debris from wearing the groove wall formed by the hobbing process during the resetting process.
