Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation devices, and particularly to a microchannel heat dissipation structure for high-efficiency thermal management. Background Art

[0002] A microchannel heat dissipation structure for high-efficiency thermal management is a heat dissipation device that introduces fluid into components to be cooled through microchannels with a hydraulic diameter between 10 micrometers and 1 millimeter. When the fluid flows in these microchannels, due to its extremely high specific surface area and microscale heat transfer characteristics, the contact area with the heat dissipation element increases significantly, enabling the heat on the heat dissipation element to be quickly conducted into the fluid and taken away through the flow of the fluid, thereby achieving high-efficiency heat dissipation. It has the advantages of high heat dissipation efficiency, small size and light weight, being applicable to high-power density devices, and being mass-produced at low cost, and is widely used in fields such as high-performance electronic devices, data centers, and electric vehicles.

[0003] Currently, the microchannel heat dissipation structure and the substrate are mostly fixedly connected. Although this method can ensure the stable operation of the device, it has drawbacks. Once the substrate is damaged or needs to be replaced due to technological upgrading or maintenance, the disassembly is extremely cumbersome. Staff not only have to spend a lot of time and energy and carefully operate with professional tools, but may also damage other components, which not only prolongs the equipment downtime, reduces work efficiency, but also affects the production progress and increases the maintenance cost. Summary of the Invention

[0004] The purpose of the present invention is to provide a microchannel heat dissipation structure for high-efficiency thermal management to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a microchannel heat dissipation structure for high-efficiency thermal management, including a substrate, on which a connection mechanism, a quick installation mechanism, and a filtering mechanism are provided;

[0007] The connection mechanism includes a microchannel plate arranged on the inner wall of the substrate. A liquid inlet manifold is fixedly connected to the left side of the microchannel plate, and a liquid outlet manifold is fixedly connected to the right side of the microchannel plate. Limiting grooves are opened on the front and back surfaces of the microchannel plate, and limiting plates are slidably connected to the inner walls of the two limiting grooves. Screws I are fixedly connected to the front and back surfaces of the two limiting plates, and the two screws I penetrate through the substrate and are slidably connected to the substrate. Manual turntables I are threadedly connected to the outer walls of the two screws I. The quick installation mechanism includes a filtering box arranged at the bottom of the substrate, and the filtering mechanism includes an outlet groove opened on the right side of the filtering box.

[0008] Further, two balance rods are fixedly connected to the front and back of the two limiting plates. A plurality of the balance rods all penetrate through the substrate and are all slidably connected to the substrate. Springs are wound around the outer walls of the plurality of balance rods. One ends of the plurality of springs are fixedly connected to the substrate, and the other ends of the plurality of springs are all fixedly connected to the two limiting plates.

[0009] Further, a liquid pump is arranged on the left side of the filter box. The left end of the liquid pump is fixedly connected to a liquid inlet pipe. The end of the liquid inlet pipe is in contact with the liquid inlet manifold. The rear end of the liquid outlet manifold is fixedly connected to a liquid outlet pipe. The end of the liquid outlet pipe is adapted to the filter box.

[0010] Further, upper half hoops are arranged on the outer walls of the liquid inlet pipe and the liquid outlet pipe. Lower half hoops are hinged to the bottoms of the two upper half hoops. Rotating blocks are rotatably connected to the inner walls of the two upper half hoops. Second screws are fixedly connected to the bottoms of the two rotating blocks.

[0011] Further, manual turntables II are threadedly connected to the outer walls of the two second screws. The two second screws and the two manual turntables II are all adapted to the two lower half hoops.

[0012] Further, a filter plate is rotatably connected to the inner wall of the filter box. One end of the filter plate close to the outlet groove extends outside the outlet groove and is slidably connected to the outlet groove.

[0013] Further, a motor is fixedly connected to the front of the filter box. The output shaft of the motor is fixedly connected to a rotating shaft through a coupling. The rotating shaft penetrates through the filter box and is rotatably connected to the filter box. A cam is fixedly connected to the outer wall of the rotating shaft. The cam is in contact with the filter plate.

[0014] Further, a waste residue collection box is slidably connected to the right side of the filter box. The waste residue collection box is adapted to both the outlet groove and the filter plate.

[0015] The present invention has the following beneficial effects:

[0016] 1. The present invention provides a connecting mechanism. During use, if the microchannel plate needs to be maintained or replaced, the operator can rotate the manual turntable 1 on the outer wall of the two screw rods 1 outward. When the manual turntable 1 is rotated, it will generate an outward pulling force on the screw rod 1 to tighten it. In this tightening process, the limit plates on the screw rod 1 will respectively use the two balance bars thereon to cause the springs on the outer walls of the balance bars to be compressed. The springs accumulate energy during the compression process to provide support for subsequent resetting. As the two screw rods 1 drive the limit plates to move outward, the limit of the upper limit groove on the microchannel plate is released. At this time, the microchannel plate can be separated from the substrate, thereby facilitating the maintenance and replacement of the microchannel plate alone. This design greatly reduces the cumbersome steps of installing and disassembling the microchannel plate, and effectively improves the installation efficiency.

[0017] 2. The present invention provides a quick-installation mechanism. When the microchannel plate is replaced, the liquid inlet pipe needs to be connected to the liquid inlet collecting pipe, and the liquid outlet pipe needs to be connected to the liquid outlet collecting pipe. At the same time, the upper half hoop is respectively sleeved at the two interfaces. After the upper half hoop is sleeved, the screw rod 2 on the upper half hoop is rotated to match it with the limiting groove of the lower half hoop. After the matching is completed, the manual turntable 2 on the outer wall of the screw rod 2 is rotated to contract the screw rod 2, so that the upper half hoop and the lower half hoop can be quickly fixed together. This measure further improves the installation efficiency.

[0018] 3. The present invention sets a filtering mechanism. When all components are adjusted in place, the object that needs heat dissipation can be placed on the top of the microchannel plate. Then, the liquid pump is started. The liquid pump draws coolant from the filter box and transports it to the liquid inlet manifold through the liquid inlet pipe. After the coolant flows through the microchannel plate, it will be collected in the liquid outlet manifold. Then, the liquid outlet manifold transports the coolant back to the filter box through the liquid outlet pipe. During the process of the coolant being transported by the liquid outlet pipe, the cooling fan can be started to dissipate heat, thereby reducing the temperature of the coolant. When the coolant flows back into the filter box, it will first be filtered by the filter plate. During the filtering process, the motor can also be started synchronously. The motor can drive the cam to rotate through the rotating shaft. Due to the special shape of the cam, when it contacts one end of the filter plate, it will cause one end of the filter plate to vibrate up and down. This vibration can cause the impurities adsorbed on the filter plate to shake off in the waste residue collection box, and the filtered clean liquid is collected again in the filter box for recycling. Through such a setting, the influence of impurities in the coolant on the entire heat dissipation system can be effectively reduced, ensuring stable and efficient operation of the system.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 8 As shown, the present invention is a microchannel heat dissipation structure for high-performance heat management, including a substrate 1, on which a connection mechanism 2, a quick-installation mechanism 3, and a filtering mechanism 4 are provided;

[0033] The connection mechanism 2 includes a microchannel plate 21 provided on the inner wall of the substrate 1. A liquid inlet manifold 22 is fixedly connected to the left side of the microchannel plate 21, and a liquid outlet manifold 23 is fixedly connected to the right side of the microchannel plate 21. Limiting grooves 24 are provided on the front and back surfaces of the microchannel plate 21. Limiting plates 25 are slidably connected to the inner walls of the two limiting grooves 24. Manual turntables 27 are fixedly connected to the front and back surfaces of the two limiting plates 25. The two manual turntables 27 are both threaded on the outer walls of the two screw rods 26. The quick-installation mechanism 3 includes a filter box 31 provided at the bottom of the substrate 1. The filtering mechanism 4 includes an outlet groove 41 provided on the right side of the filter box 31. Two balance rods 28 are fixedly connected to the front and back surfaces of the two limiting plates 25. A plurality of balance rods 28 all penetrate through the substrate 1 and are slidably connected to the substrate 1. Springs 29 are wound around the outer walls of the plurality of balance rods 28. One end of each of the plurality of springs 29 is fixedly connected to the substrate 1, and the other end of each of the plurality of springs 29 is fixedly connected to the two limiting plates 25.

[0034] By providing the connection mechanism 2, during use, if maintenance or replacement of the microchannel plate 21 is required, the operator can rotate the manual turntables 27 on the outer walls of the two screw rods 26 outward. When rotating the manual turntables 27, an outward pulling force will be generated on the screw rods 26, causing them to tighten. During this tightening process, the limiting plates 25 on the screw rods 26 will respectively rely on the two balance rods 28 thereon, causing the springs 29 on the outer walls of the balance rods 28 to be compressed. During the compression of the springs 29, energy is accumulated to provide support for subsequent reset. As the two screw rods 26 drive the limiting plates 25 to move outward, the limitation of the limiting grooves 24 on the microchannel plate 21 is released. At this time, the microchannel plate 21 can be separated from the substrate 1, thus facilitating the repair and replacement of the microchannel plate 21 alone. This design greatly reduces the cumbersome steps of installing and disassembling the microchannel plate 21 and effectively improves the installation efficiency.

[0035] A liquid pump 32 is provided on the left side of the filter box 31. The left end of the liquid pump 32 is fixedly connected to a liquid inlet pipe 33. The end of the liquid inlet pipe 33 is in contact with the liquid inlet manifold 22. The rear end of the liquid outlet manifold 23 is fixedly connected to a liquid outlet pipe 34. The end of the liquid outlet pipe 34 is adapted to the filter box 31. Upper half hoop rings 35 are provided on the outer walls of the liquid inlet pipe 33 and the liquid outlet pipe 34. Lower half hoop rings 36 are hinged to the bottoms of the two upper half hoop rings 35. Rotating blocks 37 are rotatably connected to the inner walls of the two upper half hoop rings 35. Second screws 38 are fixedly connected to the bottoms of the two rotating blocks 37. Manual turntables two 39 are threadedly connected to the outer walls of the two second screws 38. The two second screws 38 and the two manual turntables two 39 are adapted to the two lower half hoop rings 36.

[0036] By providing the quick installation mechanism 3, after the microchannel plate 21 is replaced, the liquid inlet pipe 33 needs to be connected to the liquid inlet manifold 22 respectively, and the liquid outlet pipe 34 needs to be connected to the liquid outlet manifold 23. At the same time, upper half hoop rings 35 are sleeved at the two interfaces respectively. After the upper half hoop rings 35 are sleeved, rotate the second screw 38 on the upper half hoop ring 35 to make it match the limit groove of the lower half hoop ring 36. After the matching is completed, rotate the manual turntable two 39 on the outer wall of the second screw 38 to perform a contraction operation on the second screw 38, so that the upper half hoop ring 35 and the lower half hoop ring 36 can be quickly fixed together. This measure further improves the installation efficiency.

[0037] A filter plate 42 is rotatably connected to the inner wall of the filter box 31. One end of the filter plate 42 close to the outlet groove 41 extends outside the outlet groove 41 and is slidably connected to the outlet groove 41. A motor 43 is fixedly connected to the front of the filter box 31. The output shaft of the motor 43 is fixedly connected to a rotating shaft 44 through a coupling. The rotating shaft 44 penetrates the filter box 31 and is rotatably connected to the filter box 31. A cam 45 is fixedly connected to the outer wall of the rotating shaft 44. The cam 45 is in contact with the filter plate 42. A waste residue collection box 46 is slidably connected to the right side of the filter box 31. The waste residue collection box 46 is adapted to both the outlet groove 41 and the filter plate 42.

[0038] By setting up the filtering mechanism 4, when all components are adjusted in place, an object to be cooled can be placed on top of the microchannel plate 21. Then, the liquid pump 32 is started. The liquid pump 32 sucks the coolant from the filter box 31 and transports it into the inlet liquid manifold 22 through the inlet liquid pipe 33. After flowing through the microchannel plate 21, the coolant is collected in the outlet liquid manifold 23. Subsequently, the outlet liquid manifold 23 transports the coolant back to the filter box 31 through the outlet liquid pipe 34. During the process of transporting the coolant through the outlet liquid pipe 34, the cooling fan 391 can be started to cool it, thereby reducing the temperature of the coolant. When the coolant flows back into the filter box 31, it first passes through the filter plate 42. During the filtering process, the motor 43 can be synchronously started. The motor 43 drives the cam 45 to rotate through the rotating shaft 44. Due to the special shape of the cam 45, when it contacts one end of the filter plate 42, it causes that end of the filter plate 42 to vibrate up and down. This vibration can shake the impurities adsorbed on the filter plate 42 into the waste residue collection box 46, while the filtered liquid is collected again in the filter box 31 for recycling. Through such a setting, the influence of impurities in the coolant on the entire cooling system can be effectively reduced, ensuring the stable and efficient operation of the system.

[0039] During use, if the microchannel plate 21 needs to be maintained or replaced, the operator can rotate the manual turntable 27 on the outer wall of the two screw rods 26 outward. When the manual turntable 27 is rotated, it will generate an outward pulling force on the screw rod 26 to tighten it. In this tightening process, the limit plate 25 on the screw rod 26 will respectively use the two balance bars 28 thereon to cause the spring 29 on the outer wall of the balance bar 28 to be compressed. The spring 29 accumulates energy during the compression process to provide support for subsequent resetting. As the two screw rods 26 drive the limit plate 25 to move outward, the limit of the upper limit groove 24 of the microchannel plate 21 is released. At this time, the microchannel plate 21 It can be separated from the substrate 1, so that it is convenient to repair and replace the microchannel plate 21 separately. This design greatly reduces the tedious steps of installing and disassembling the microchannel plate 21, and effectively improves the installation efficiency; when the microchannel plate 21 is replaced, the liquid inlet pipe 33 needs to be connected to the liquid inlet manifold 22, and the liquid outlet pipe 34 needs to be connected to the liquid outlet manifold 23. At the same time, the upper half hoop 35 is respectively sleeved on the two interfaces. After the upper half hoop 35 is sleeved, the screw rod 2 38 on the upper half hoop 35 is rotated to match it with the limit groove of the lower half hoop 36. After the matching is completed, the manual turntable 2 39 on the outer wall of the screw rod 2 38 is rotated to retract the screw rod 2 38 , so that the upper half hoop 35 and the lower half hoop 36 can be quickly fixed together, this measure further improves the installation efficiency; when all the parts are adjusted in place, the object that needs heat dissipation can be placed on the top of the microchannel plate 21, and then the liquid pump 32 is started. The liquid pump 32 will absorb the coolant from the filter box 31 and transport it to the liquid inlet manifold 22 through the liquid inlet pipe 33. After the coolant flows through the microchannel plate 21, it will be collected in the liquid outlet manifold 23, and then the liquid outlet manifold 23 will transport the coolant back to the filter box 31 through the liquid outlet pipe 34. In the process of transporting the coolant through the liquid outlet pipe 34, the cooling fan 391 can be started to dissipate heat, thereby reducing The temperature of the low coolant, when the coolant flows back into the filter box 31, it will first be filtered by the filter plate 42. During the filtering process, the motor 43 can also be started synchronously. The motor 43 can drive the cam 45 to rotate through the rotating shaft 44. Due to the special shape of the cam 45, when it contacts one end of the filter plate 42, it will cause one end of the filter plate 42 to vibrate up and down. This vibration can make the impurities adsorbed on the filter plate 42 fall into the waste residue collection box 46, and the filtered liquid is collected again in the filter box 31 for recycling. Through such a setting, the impact of impurities in the coolant on the entire heat dissipation system can be effectively reduced, ensuring stable and efficient operation of the system.
