Description

Technical Field

[0001] This application relates to the technical field of liquid cooling heat dissipation product manufacturing, and in particular to a tooling for detecting microchannel debris residue in liquid cooling products. Background Technology

[0002] With the rapid development of fields such as artificial intelligence and high-performance computing, the computing power and power density of chips (such as GPUs) continue to rise, and the power distribution exhibits high non-uniformity. Traditional two-dimensional microchannel liquid cooling plates, due to their limited heat dissipation capacity and relatively fixed channel layout, are difficult to flexibly and accurately adapt to the uneven heat flux density on the surface of modern chips, resulting in prominent local hot spots, which has become a bottleneck restricting the further development of chip performance.

[0003] To address this challenge, advanced liquid cooling products employing complex microstructures such as three-dimensional short-loop jet channels have emerged in the industry. These three-dimensional microchannels differ from traditional long, straight two-dimensional channels, featuring shorter fluid paths and more complex geometries, enabling efficient localized impact jet cooling and thus better resolving the issue of localized overheating in chips.

[0004] However, after manufacturing, these complex three-dimensional microchannels inevitably retain contaminants such as metal powder and support material debris. If cleaning is incomplete, these residues can clog the narrow microchannels during operation, leading to a sharp decline in heat dissipation efficiency and even causing the chip to burn out due to overheating, posing significant quality and reliability risks. Currently, there is a lack of effective testing fixtures for liquid-cooled products with such complex internal three-dimensional microchannel structures. Therefore, there is an urgent need for a dedicated testing fixture capable of accurately detecting debris residue within the complex microchannels of liquid-cooled products. Summary of the Invention

When the water supply pipeline is connected to the outlet water pipe, the inlet water pipe is connected to the return water pipeline. The particle size detection device is installed on the return water pipeline.

[0009] Optionally, the inlet and outlet water pipeline system is further equipped with a pulse boosting module. The pulse boosting module includes a drain pipe, a booster tank, a guide pipe, a piston, and an electric push rod. The drain pipe is connected to the booster pump and the booster tank respectively. The guide pipe is connected to the booster tank and the water supply pipeline respectively. The connection end of the guide pipe and the water supply pipeline is located between the booster pump and the reversing valve. The piston is slidably disposed in the booster tank. The electric push rod is used to drive the piston to slide back and forth along the axial direction of the booster tank.

[0010] Optionally, the piston is provided with a water inlet, and a sealing plug is slidably provided on the top of the piston along the axial direction of the pressurization tank. The sealing plug is adapted to the water inlet and is used to close the water inlet. A guide rod is fixedly provided on the piston, and the sealing plug is slidably passed through the guide rod. The movable rod of the electric push rod is fixedly connected to the sealing plug.

[0011] Optionally, it also includes a control system, which is electrically connected to the pneumatic cylinder, booster pump, reversing valve, electric push rod and particle size detection device, and is equipped with a central control switch.

[0012] Optionally, both the inlet and outlet connectors are equipped with an automatic opening and closing module to control the automatic opening or closing of the inlet and outlet connectors.

[0013] Optionally, the automatic opening and closing module includes a sealing sleeve and a return spring. The ends of the water inlet and water outlet are both closed, and the side walls of the water inlet and water outlet are provided with multiple openings. The sealing sleeve is slidably fitted on the water inlet or water outlet.

[0014] Optionally, the end of the sealing sleeve away from the clamping block is provided with a chamfer, and the side wall of the chamfer of the sealing sleeve is provided with an annular groove along the circumference of the sealing sleeve.

[0016] Optionally, a pressing plate is slidably provided at one end of the clamping block near the positioning seat, and a buffer spring is provided on the clamping block to drive the pressing plate to slide away from the clamping block. The pressing plate is provided with a plurality of top blocks for abutting against the liquid-cooled product.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application enables precise detection of debris residue within the complex microchannels of liquid-cooled products, significantly improving detection efficiency. Specifically, it achieves rapid positioning of the liquid-cooled product through a positioning seat and positioning groove; it automatically clamps the liquid-cooled product by driving the clamping block to slide using a pneumatic cylinder, reducing manual operation and labor intensity; simultaneously, it enables rapid and precise connection of the inlet and outlet connectors to the coolant inlet and outlet of the liquid-cooled product, respectively; and it accurately determines whether there is debris residue within the product by detecting the concentration of debris particles in the water circuit using a particle size analyzer.

[0019] 2. This application controls the water flow direction through a reversing valve to achieve alternating forward and reverse flushing. During forward flushing, water flows in from the inlet and out from the outlet, while during reverse flushing, water flows in from the outlet and out from the inlet. This bidirectional alternating flushing mode can more thoroughly remove residues in different directions within the microchannel, avoiding "dead zone" residues caused by unidirectional flushing, and further improving the detection accuracy of debris residues.

[0020] 3. This application incorporates automatic opening and closing modules on both the inlet and outlet water connectors. When the inlet and outlet water connectors are not connected to the product's coolant inlet and outlet, the automatic opening and closing modules close the inlet and outlet water connectors respectively. This prevents liquid leakage from the inlet and outlet water pipeline system and prevents it from dripping onto the work surface. At the same time, this reduces residual air in the inlet and outlet water pipeline system, ensuring normal water pressure during the flushing process. When the inlet and outlet water connectors are connected to the product's coolant inlet and outlet, the automatic opening and closing modules automatically open, improving the ease of operation.

[0021] 4. This application utilizes a buffer spring and pressure plate design. When the clamping block clamps the liquid-cooled product, the buffer spring provides elastic support, preventing surface damage caused by rigid contact between the clamping block and the product. Simultaneously, it ensures a tighter connection between the inlet and outlet connectors and the product's coolant inlet and outlet, reducing the risk of leakage. Attached Figure Description

[0029] The following will be combined with the appendix Figure 1 -Appendix Figure 6 The technical solutions in the embodiments of the present invention are clearly and completely described herein. The described embodiments are only possible technical implementations of the present invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of the present invention without creative effort, and these embodiments are also within the protection scope of the present invention.

[0030] This application effectively removes residual contaminants from the interior of complex three-dimensional microchannels, solving the technical problems of traditional cleaning methods being inefficient and unable to thoroughly clean complex flow channels. The main approach adopted is as follows:

[0031] This application discloses a fixture for detecting microchannel debris residue in liquid-cooled products. (Refer to...) Figure 1 and Figure 2 The system includes a base 1, positioning seats 2, clamping blocks 3, pneumatic cylinders 4, an inlet / outlet water piping system 5, and a particle size detection device 57. Multiple positioning seats 2 are fixedly mounted on the base 1. Multiple clamping blocks 3 are also provided and slidably mounted on the base 1, with each clamping block 3 corresponding to one of the positioning seats 2. Multiple pneumatic cylinders 4 are fixedly mounted on the base 1, each corresponding to one of the clamping blocks 3, and are used to drive the corresponding clamping block 3 to slide. Each clamping block 3 is provided with an inlet connector 31 and an outlet connector 32. The inlet / outlet water piping system 5 is connected to the inlet connector 31 and the outlet connector 32. The particle size detection device 57 determines whether there is residual debris in the product by detecting the concentration of debris particles in the water circuit. This application enables rapid and accurate detection of residual debris in the complex microchannels inside liquid-cooled products.

[0032] Specifically, base 1 serves as the foundation for the entire tooling installation. Base 1 is typically made of high-strength metal materials, such as stainless steel, which provides excellent stability and load-bearing capacity, ensuring that the tooling will not shake or shift during operation. Alternatively, high-strength engineering plastics can be used to make base 1 to reduce weight and cost. Base 1 is usually flat with a smooth surface, facilitating the installation and securing of other components.

[0033] Reference Figure 2 The positioning seat 2 is fixedly mounted on the base 1, and has a positioning groove 21 adapted to the liquid cooling product. The positioning seat 2 is generally made of aluminum alloy, which is lightweight yet strong. The shape and size of the positioning groove 21 are designed according to the shape of the liquid cooling product, ensuring accurate and rapid positioning. Furthermore, the positioning seat 2 can be detachably mounted on the base 1 using bolts or other means, facilitating replacement for different liquid cooling products.

[0034] Reference Figure 2 and Figure 3 The clamping block 3 is typically made of steel, possessing a certain degree of hardness and wear resistance. The inlet connector 31 and outlet connector 32 are generally made of copper, offering corrosion resistance and good sealing. A pressure plate 33 is slidably mounted on one end of the clamping block 3 near the positioning seat 2. A buffer spring 34 is mounted on the clamping block 3 to drive the pressure plate 33 away from the clamping block 3. Multiple top blocks 331 are mounted on the pressure plate 33 to abut against the liquid-cooled product. The pressure plate 33 is typically made of aluminum, being lightweight and possessing a certain degree of toughness. The buffer spring 34 is a cylindrical helical spring with a suitable elastic modulus. The top blocks 331 can be rubber blocks with a soft surface, preventing damage to the surface of the liquid-cooled product. When the clamping block 3 slides towards the positioning seat 2 under the drive of the pneumatic cylinder 4, the top blocks 331 on the pressure plate 33 contact the liquid-cooled product first, compressing the buffer spring 34 and providing elastic support, thus preventing surface damage caused by rigid contact between the clamping block 3 and the product. At the same time, this elastic support ensures a tighter connection between the inlet connector 31 and the outlet connector 32 when they are connected to the product's coolant inlet and coolant outlet, reducing the risk of leakage.

[0035] Reference Figure 2The pneumatic cylinder 4 is fixedly mounted on the base 1 and connected to the clamping block 3. It drives the clamping block 3 to slide, allowing the inlet connector 31 and outlet connector 32 of the clamping block 3 to connect with the coolant inlet and outlet of the liquid-cooled product, respectively. The pneumatic cylinder 4 is typically a standard industrial pneumatic cylinder, which has advantages such as high thrust and fast response. A connecting block 41 is fixedly mounted on the piston rod 64 of the pneumatic cylinder 4. The clamping block 3 has a connecting groove adapted to the connecting block 41, and the connecting block 41 and the clamping block 3 are fixed together by bolts. When the pneumatic cylinder 4 is vented, the piston rod 64 extends or retracts, thereby driving the clamping block 3 to slide. The positioning seat 2 is detachably mounted on the base 1 by bolts, and the clamping block 3 and connecting block 41 are also detachably connected by bolts. This facilitates the replacement of positioning seats 2 and clamping blocks 3 of different specifications to adapt to different models and interface positions of liquid-cooled products, improving the versatility and flexible production capabilities of the tooling and reducing equipment investment costs.

[0036] Reference Figure 4 Specifically, the inlet and outlet water pipeline system 5 includes a water supply pipeline 51, a booster pump 52, a return water pipeline 53, a reversing valve 54, an inlet water pipe 55, and an outlet water pipe 56. The water supply pipeline 51, return water pipeline 53, inlet water pipe 55, and outlet water pipe 56 are generally made of transparent rubber hoses, possessing good flexibility and corrosion resistance. The inlet water pipe 55 is connected to the inlet connector 31 on the clamping block 3, and the outlet water pipe 56 is connected to the outlet connector 32 on the clamping block 3. The booster pump 52 is installed on the water supply pipeline 51 to increase the water supply pressure. The booster pump 52 can be a high-pressure plunger pump equipped with multiple outlets. The water supply pipeline 51, return water pipeline 53, inlet water pipe 55, and outlet water pipe 56 are all connected to the reversing valve 54. A particle size detection device 57 is installed on the return water pipeline 53; specifically, a particle concentration detector can be used to detect the particle concentration in the return water pipeline. The reversing valve 54 controls the connection between the water supply pipe 51 and the inlet pipe 55 or the outlet pipe 56. When the water supply pipe 51 is connected to the inlet pipe 55, the outlet pipe 56 is connected to the return pipe 53. When the water supply pipe 51 is connected to the outlet pipe 56, the inlet pipe 55 is connected to the return pipe 53. This allows for alternating forward and reverse flushing. During forward flushing, water enters from the inlet and exits from the outlet; during reverse flushing, water enters from the outlet and exits from the inlet. This bidirectional alternating flushing mode can more thoroughly remove residues in different directions within the microchannel, avoiding the "dead zone" residues caused by unidirectional flushing, and further improving detection accuracy.

[0037] Reference Figure 4The inlet and outlet water pipeline system 5 is also equipped with a pulse booster module 6. By generating periodic pulse water flow in the inlet and outlet water pipeline system 5, turbulence and impact effects are generated in the microchannel, which can effectively remove residual pollutants inside the complex three-dimensional microchannel. Compared with the traditional constant water flow, it has a stronger peeling ability for pollutants such as powder and debris attached to the channel wall, and is especially suitable for cleaning the corners and dead areas of complex three-dimensional microchannels.

[0038] Reference Figure 4 and Figure 5 Specifically, the pulse booster module 6 includes a drain pipe 61, a booster tank 62, a guide pipe 63, a piston 64, and an electric push rod 65. The drain pipe 61 is connected to the top of the booster pump 52 and the booster tank 62, respectively. The guide pipe 63 is connected to the bottom of the water supply pipeline 51 and the booster tank 62, respectively, and the connection end of the guide pipe 63 with the water supply pipeline 51 is located between the booster pump 52 and the reversing valve 54. The piston 64 is slidably disposed inside the booster tank 62 and is adapted to the booster tank 62. The electric push rod 65 is fixedly disposed at the top of the booster tank 62 and is used to drive the piston 64 to slide back and forth along the axial direction of the booster tank 62. When the electric push rod 65 pushes the piston 64 to reciprocate within the booster tank 62, periodic pressure changes are generated within the booster tank 62, thereby forming a periodic pulse water flow in the inlet and outlet water pipeline system 5. Compared to traditional solenoid valve pulse methods, the pulse pressure is more stable and has a wider adjustable range. Furthermore, through the energy storage function of the booster tank 62, it can generate higher intensity pulse pressure, resulting in better removal of stubborn contaminants. At the same time, it has a relatively simple structure, high reliability, and low maintenance costs.

[0039] Reference Figure 5 Specifically, a sealing plug 642 is provided on the piston 64, and a sealing plug 642 is slidably mounted on the top of the piston 64 along the axial direction of the pressurization tank 62. The sealing plug 642 is adapted to the water inlet 641 and is used to seal the water inlet 641. A guide rod 643 is fixedly mounted on the piston 64, and the sealing plug 642 slides through the guide rod 643. The movable rod of the electric push rod 65 passes through the pressurization tank 62 and is fixedly connected to the sealing plug 642. The sealing plug 642 is generally made of silicone material, which is soft and has a good sealing effect. The guide rod 643 is usually made of stainless steel, which has high strength and corrosion resistance. When the electric push rod 65 pushes the piston 64 downward, the sealing plug 642 closes the water inlet 641 under the action of gravity and water pressure. At this time, the water below the piston 64 is compressed, forming a high-pressure water flow in the pressurization tank 62. When the electric push rod 65 pulls the piston 64 upward, the sealing plug 642 slides upward on the guide rod 643, and the water inlet 641 opens, so as to avoid affecting the normal pressure-stabilized water flow in the water supply pipeline 51 during the upward sliding of the piston 64.

[0040] Reference Figure 2The system also includes a control system 7, which is electrically connected to multiple pneumatic cylinders 4, a booster pump 52, a reversing valve 54, an electric push rod 65, and a particle size detection device 57. The control system 7 is equipped with a central control switch 71. The control system 7 typically uses a programmable logic controller (PLC), which has powerful programming and control functions. The central control switch 71 can be a handle switch or a touchscreen switch, making operation simple. The operator only needs to turn on the central control switch 71, and the control system 7 can automatically control the extension and retraction of the multiple pneumatic cylinders 4, the start and stop of the booster pump 52, the switching of the reversing valve 54, and the movement of the electric push rod 65, achieving automated control of the entire rinsing process. Simultaneously, the particle concentration data detected by the particle size detection device 57 is transmitted to the control system 7. When the particle concentration is lower than a preset value, the control system 7 can automatically shut off the central control switch 71.

[0041] Reference Figure 3 and Figure 6 Both the inlet connector 31 and the outlet connector 32 are equipped with automatic opening and closing modules 8 to control the automatic opening and closing of the inlet connector 31 and the outlet connector 32. By installing automatic opening and closing modules 8 on both the inlet connector 31 and the outlet connector 32, when the inlet connector 31 and the outlet connector 32 are not connected to the product's coolant inlet and coolant outlet, the automatic opening and closing modules 8 close the inlet connector 31 and the outlet connector 32 respectively. This prevents liquid leakage in the inlet and outlet pipeline system 5 and dripping onto the work surface. At the same time, this reduces the amount of air residue in the inlet and outlet pipeline system 5 and ensures normal water pressure during the rinsing process. When the inlet connector 31 and the outlet connector 32 are connected to the product's coolant inlet and coolant outlet, the automatic opening and closing modules 8 automatically open, improving the convenience of operation.

[0042] Reference Figure 6 Specifically, the automatic opening and closing module 8 includes a sealing sleeve 81 and a return spring 82. The ends of the inlet connector 31 and the outlet connector 32 are both closed, and the side walls of both the inlet connector 31 and the outlet connector 32 have multiple openings 35. The sealing sleeve 81 is slidably fitted onto the inlet connector 31 or the outlet connector 32. The return spring 82 drives the sealing sleeve 81 to slide away from the clamping block 3. When the inlet connector 31 and the outlet connector 32 are not connected to the product's coolant inlet and coolant outlet, the sealing sleeve 81, under the elastic force of the return spring 82, blocks the openings 35 on the inlet connector 31 and the outlet connector 32, thus closing the inlet connector 31 and the outlet connector 32. When the inlet connector 31 and outlet connector 32 are connected to the coolant inlet and coolant outlet of the liquid cooling product, the sealing sleeve 81 abuts against the liquid cooling product. As the clamping block 3 slides, the sealing sleeve 81 slides closer to the clamping block 3, thereby removing the obstruction of the opening 35 on the inlet connector 31 and outlet connector 32 and realizing the automatic opening of the inlet connector 31 and outlet connector 32.

[0043] Reference Figure 6 The sealing sleeve 81 has a chamfer at the end away from the clamping block 3. An annular groove is formed on the side wall of the chamfered end of the sealing sleeve 81 along its circumference. A sealing ring 811 is fitted inside the annular groove of the sealing sleeve 81. An annular support is fixedly provided on the side wall of both the inlet connector 31 and the outlet connector 32. The annular support is located on the side of the sealing sleeve 81 closest to the clamping block 3. A sealing gasket 36 is provided at the end of the annular support closest to the sealing sleeve 81 to abut against the end of the sealing sleeve 81. The sealing ring 811 is generally a rubber sealing ring 811, which enhances the sealing effect between the sealing sleeve 81 and the coolant inlet and outlet of the liquid-cooled product. The sealing gasket 36 is also made of rubber. When the sealing sleeve 81 slides towards the clamping block 3 and opens the inlet connector 31 and the outlet connector 32, the end of the sealing sleeve 81 presses against the sealing gasket 36, thereby enhancing the sealing effect between the sealing sleeve 81 and the inlet connector 31 and the outlet connector 32.

[0044] The implementation principle of the microchannel debris residue detection fixture for liquid-cooled products in this embodiment is as follows: The positioning seat 2 and positioning groove 21 enable rapid positioning of the liquid-cooled product; the pneumatic cylinder 4 drives the clamping block 3 to slide, achieving automatic clamping of the liquid-cooled product, reducing manual operation and labor intensity. Simultaneously, it enables rapid and precise connection of the inlet connector 31 and outlet connector 32 to the coolant inlet and outlet of the liquid-cooled product, respectively; the pulse booster module 6 generates periodic pulsed water flow within the inlet and outlet water pipeline system 5, creating turbulence and impact effects within the microchannel, effectively removing residual contaminants inside the complex three-dimensional microchannel. Compared to traditional constant water flow, it has a stronger peeling ability for powder, debris, and other contaminants adhering to the channel wall, making it particularly suitable for cleaning the corners and dead zones of complex three-dimensional microchannels. Therefore, it can effectively remove residual contaminants inside the complex three-dimensional microchannel and achieve efficient and accurate detection of debris residue within the complex microchannels of the liquid-cooled product.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
