Description

Technical Field

[0001] The present invention relates to the technical field of GPU cluster servers, and in particular to a special cooling device for computer GPU cluster servers. Background Art

[0002] A computer cluster is a combination of multiple computers that work together to complete computing tasks. A GPU (Graphics Processing Unit) cluster server is a server system with GPU as the main computing core in the cluster architecture. GPU has powerful parallel computing capabilities and can efficiently process large amounts of data. With the growing demand for high-performance computing, GPU cluster servers have been widely used in fields such as artificial intelligence, deep learning, scientific computing, and graphics rendering. However, GPUs generate a lot of heat during operation, especially in high-load and high-density deployment cluster environments. Heat dissipation becomes a key factor restricting their performance and stable operation.

[0003] The existing Chinese patent with publication number CN113220088B includes a box body, a motor, a rotating mechanism, a reciprocating mechanism, a pushing mechanism, a ventilation mechanism, a knocking mechanism and a dust removal mechanism. The top wall of the box body is welded and fixed with the motor, the output end of the motor is welded and fixed with the rotating mechanism, the side wall of the box body is welded and fixed with the pushing mechanism, the inner wall of the box body is welded and fixed with a reciprocating mechanism that drives the pushing mechanism to move, and the side wall of the box body is provided with a ventilation mechanism for circulating the gas inside the box body.

[0004] When the above device is in use, when the push rod slides to the left with the rectangular frame, the push rod squeezes the coolant in the cooling box from the liquid outlet joint to the circulation pipe through the piston for circulation. The circulation pipe is embedded in the inner wall of the box to further cool the high temperature generated in the box, which significantly improves the heat dissipation performance. However, in actual use, since the flow rate and flow of the coolant in the circulation pipe are fixed, the temperature of the cluster server continues to rise after working for a long time, resulting in low heat dissipation efficiency and inability to meet the heat dissipation requirements. Therefore, it is difficult to automatically adjust the flow rate and flow of the coolant according to the internal temperature of the cluster server.

[0005] To this end, we propose a special cooling device for computer GPU cluster servers. Summary of the Invention

[0011] Preferably, the circular plate is provided with a detection mechanism for real-time monitoring of the interior of the box, the detection mechanism includes a support block fixedly connected to the side of the bottom of the circular plate away from the second piston cylinder, the support block is fixedly connected to the side close to the fixed block with a pressure sensor connected to the external controller through a signal, and the pressure sensor is fixedly connected to the opposite surface of the fixed block with a first spring that applies pressure to the pressure sensor.

[0012] Preferably, the cooling mechanism includes an inner wall of a first piston cylinder axially connected to a first piston rod for extracting and discharging the coolant inside the cooling box, an inner wall of the liquid outlet pipe near one end of the first piston cylinder is fixedly connected to a one-way liquid inlet valve for the first piston rod to quantitatively extract the coolant inside the cooling box, and an inner wall of the injection pipe near one end of the first piston cylinder is fixedly connected to a one-way liquid discharge valve for the first piston rod to quantitatively discharge the coolant inside the first piston cylinder.

[0013] Preferably, the end of the first piston rod away from the first piston cylinder is fixedly connected to a rectangular frame, and the inner wall of the rectangular frame is movably connected to an eccentric block for the fixed block to pull the first piston rod for axial reciprocating movement, and the end of the eccentric block is fixedly connected to the bottom end of the fixed block.

[0014] Preferably, a movable groove is provided on one side of the box body close to the filter plate, and the inner wall of the movable groove is connected to a T-shaped rod for lifting and moving. One end of the T-shaped rod close to the rectangular frame is fixedly rotatably connected to an adjusting rod that pushes the T-shaped rod to lift and reciprocate, and one end of the adjusting rod away from the T-shaped rod is fixedly rotatably connected to the rectangular frame, and the end of the movable groove and the opposite surface of the T-shaped rod are fixedly connected to a second spring that guides the T-shaped rod to reset and move, and the bottom end of the T-shaped rod is fixedly connected to an inverted U-shaped frame, and the opposite surfaces of the two ends of the T-shaped rod are penetrated and fixedly rotatably connected to cleaning rollers for cleaning dust on the surface of the filter plate.

[0015] Preferably, the box body is provided with an auxiliary mechanism for driving the cleaning roller to roll and clean the surface of the filter plate. The auxiliary mechanism includes a rack fixedly connected to the side of the box body close to the filter plate, which drives the cleaning roller to rotate on a fixed axis, and the end of the cleaning roller close to the rack is coaxially fixed with a third gear that meshes with the teeth on the rack for transmission.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, the heat dissipation structure, with the fan mounted within the exhaust duct via a fixed rod, rapidly expels hot air from the enclosure. Simultaneously, the filter plate design allows cool air from outside to enter the enclosure, creating a favorable air convection cycle and effectively reducing the temperature within the enclosure. Furthermore, the filter plate also provides a filtering function, effectively blocking dust from entering the enclosure and preventing dust accumulation on the server surface. This reduces heat dissipation issues caused by dust accumulation and further extends the server's service life. This design not only improves heat dissipation efficiency but also optimizes the server's operating environment, ensuring long-term stable operation.

[0017] Second, a sensitive temperature detection system is formed by installing a circular plate, a second piston cylinder, a second piston rod, a fixed block, a support block, a pressure sensor, and a first spring at the bottom of the fan. The alcohol filled in the second piston cylinder expands when heated, pushing the second piston rod to move, which in turn applies pressure to the pressure sensor through the first spring. The pressure sensor converts the detected pressure value into an electrical signal and transmits it to the external controller in real time, achieving real-time and accurate monitoring of the internal temperature of the box, allowing staff to keep track of the server's operating temperature status at all times. When the temperature rises abnormally, the system can promptly issue an alarm, reminding staff to take measures, effectively avoiding server failures caused by overheating and improving the safety and reliability of the system. In addition, this automatic monitoring function reduces the frequency of manual inspections and reduces maintenance costs.

[0018] 3. Through the coordinated action of the first piston cylinder, the first piston rod, the one-way liquid inlet valve and the one-way liquid discharge valve, the automatic adjustment function of the coolant flow rate and flow is realized. As the first piston rod moves axially back and forth in the first piston cylinder, the coolant is quantitatively extracted from the cooling box through the one-way liquid inlet valve, and the coolant is injected into the circulation pipe through the one-way liquid discharge valve. When the detection mechanism detects that the temperature inside the box has risen, the fixed block will push the first piston rod to increase the movement stroke, thereby increasing the extraction and discharge volume of the coolant, increasing the flow rate of the coolant, and further enhancing the cooling effect. On the contrary, when the temperature drops, the movement stroke of the first piston rod decreases, and the flow rate and flow of the coolant also decrease accordingly, thereby saving energy. The flow rate and flow of the coolant can be dynamically adjusted according to the actual operating temperature of the cluster server, ensuring that the server can maintain the best cooling effect under different load conditions, effectively solving the problem that the flow rate and flow of the traditional cooling system are fixed and cannot be automatically adjusted according to temperature changes, and significantly improving the adaptability and efficiency of the cooling system.

[0019] Fourth, as the first piston rod and the rectangular frame reciprocate, the adjustment rod pushes the T-shaped rod to move up and down and back and forth. At the same time, the third gear on the cleaning roller engages with the rack, allowing the third gear to drive the cleaning roller on the inverted U-shaped frame to roll and clean the surface of the filter plate, further improving the cleaning effect. It can effectively remove dust from the surface of the filter plate, maintain the cleanliness of the filter plate, ensure smooth air circulation, thereby improving heat dissipation efficiency, and reduce the problem of poor heat dissipation caused by dust clogging the filter plate. In addition, the rolling cleaning method of the cleaning roller is more efficient and convenient than traditional manual cleaning, reducing maintenance workload and downtime, and improving the overall operating efficiency and maintenance convenience of the system. Through the automated cleaning function of the auxiliary mechanism, the present invention can maintain good heat dissipation performance for a long time, further improving the reliability and stability of the cooling device.

[0020] The coordinated use of the above-mentioned structure solves the problem that, in actual use of the existing device, since the flow rate and flow of the coolant in the circulation pipe are fixed, the temperature of the cluster server continues to rise after working for a long time, resulting in low heat dissipation efficiency and inability to meet heat dissipation requirements, and therefore it is difficult to automatically adjust the coolant flow rate and flow according to the internal temperature of the cluster server.

[0026] On the basis of the first embodiment, further steps are as follows: The heat dissipation mechanism includes an exhaust pipe 9 that is passed through and fixedly connected to the end of the box body 1, and a fixing rod 10 is fixedly connected to the inner wall of the exhaust pipe 9.

Example 3:

[0029] On the basis of the second embodiment, further steps are as follows: The fan 11 is provided with a detection mechanism for real-time monitoring of the internal temperature of the box 1, and the detection mechanism includes a circular plate 14 coaxially fixedly connected to the bottom end of the fan 11, and a second piston cylinder 15 is fixedly connected to one side of the bottom of the circular plate 14. The inner wall of the second piston cylinder 15 is movably connected to a second piston rod 16 that performs axial reciprocating movement, and the end of the second piston rod 16 away from the second piston cylinder 15 is fixedly connected to a fixed block 17, and the inner wall of the second piston cylinder 15 away from the fixed block 17 is provided with alcohol that is easily expanded by heat.

[0030] The circular plate 14 is provided with a detection mechanism for real-time monitoring of the interior of the box body 1. The detection mechanism includes a support block 21 fixedly connected to the side of the bottom of the circular plate 14 away from the second piston cylinder 15, and a pressure sensor 22 fixedly connected to the side of the support block 21 close to the fixed block 17, which is connected to the external controller through a signal. A first spring 23 that applies pressure to the pressure sensor 22 is fixedly connected to the opposite surface of the pressure sensor 22 and the fixed block 17.

[0031] During use, the circular plate 14 is provided on the fan 11, and the circular plate 14 is coaxially fixedly connected to the fan 11, so that the circular plate 14 can rotate synchronously with the fan 11 on a fixed axis, and the second piston cylinder 15 provided on the circular plate 14 fixes and supports the second piston cylinder 15 on the circular plate 14, and the second piston rod 16 provided on the second piston cylinder 15 can make the second piston rod 16 axially move and connect to the inner wall of the second piston cylinder 15, and the fixed block 17 provided on the second piston rod 16 is fixedly supported on the second piston rod 16, and the support block 21 provided on the circular plate 14 and the pressure sensor 22 provided on the support block 21 enable the support block 21 to fix and support the pressure sensor 22 on the circular plate 14, and at the same time, the support block 21 and the pressure sensor 22 are on the same horizontal line as the fixed block 17, and the first spring 23 provided on the pressure sensor 22 fixes and supports the two ends of the first spring 23 on the pressure sensor 22 and the fixed block 17 respectively.

[0032] like Figure 7 As shown, alcohol is set on the inner wall of the second piston cylinder 15, and the end of the second piston cylinder 15 away from the fixed block 17 is in a sealed state. As the temperature inside the box body 1 gradually increases, the second piston cylinder 15 contacts the hot air inside the box body 1, so that the second piston cylinder 15 can conduct heat to the inner wall and contact with alcohol, and the alcohol expands due to heat. At this time, the inner wall of the second piston cylinder 15 away from the fixed block 17 is in a positive pressure state, so that the alcohol can push the second piston rod 16 and the fixed block 17 to move horizontally in the direction close to the pressure sensor 22. At the same time, the first spring 23 contracts under the action of the fixed block 17 and applies pressure to the pressure sensor 22. force, and the pressure sensor 22 is connected to the external controller through a signal, and then the pressure sensor 22 can convert the detected pressure value into an electrical signal and remotely transmit it to the external controller, so that the staff can grasp the operating temperature status of the server at any time. When the pressure detected by the pressure sensor 22 exceeds the set threshold, the system can issue an alarm in time to remind the staff to take measures, thereby effectively avoiding server failures caused by overheating and improving the safety and reliability of the server during use. The above-mentioned pressure sensor 22 converts the detected pressure value into an electrical signal and remotely transmits it to the external controller, which is a prior art content well known to people in this field, and will not be repeated here.

[0033] When the temperature inside the box 1 drops, the alcohol inside the second piston cylinder 15 can return to its initial state, and then the first spring 23 can push the second piston rod 16 through the fixed block 17 under the action of its own elastic force to reset and move horizontally in the direction away from the pressure sensor 22. At the same time, the pressure applied by the first spring 23 to the pressure sensor 22 decreases accordingly. Example 4:

[0034] On the basis of the third embodiment, further steps are as follows: The cooling mechanism includes an inner wall of a first piston cylinder 5 axially connected to a first piston rod 18 for extracting and discharging the coolant inside the cooling box 4; the inner wall of the liquid outlet pipe 6 near one end of the first piston cylinder 5 is fixedly connected to a one-way liquid inlet valve 601 for the first piston rod 18 to quantitatively extract the coolant inside the cooling box 4; the inner wall of the injection pipe 7 near one end of the first piston cylinder 5 is fixedly connected to a one-way liquid discharge valve 701 for the first piston rod 18 to quantitatively discharge the coolant inside the first piston cylinder 5.

[0035] The end of the first piston rod 18 away from the first piston cylinder 5 is fixedly connected to a rectangular frame 19, and the inner wall of the rectangular frame 19 is movably connected to an eccentric block 20 for the fixed block 17 to pull the first piston rod 18 for axial reciprocating movement. The end of the eccentric block 20 is fixedly connected to the bottom end of the fixed block 17.

[0036] During use, the first piston rod 18 provided on the first piston cylinder 5 enables the first piston rod 18 to be axially moved and connected to the inner wall of the first piston cylinder 5, and the rectangular frame 19 provided on the first piston rod 18 fixes and supports the rectangular frame 19 on the first piston rod 18, and the eccentric block 20 provided on the rectangular frame 19 supports the eccentric block 20, so that the eccentric block 20 can be horizontally moved and connected to the inner wall of the rectangular frame 19.

[0037] like Figure 7 and Figure 8 As shown, first, the eccentric block 20 is fixed on the support on the fixed block 17, and the eccentric block 20 deviates from the center position of the circular plate 14. As the circular plate 14 rotates along a fixed axis, the eccentric block 20 can pull the first piston rod 18 through the rectangular frame 19 to perform axial reciprocating movement on the inner wall of the first piston cylinder 5. The one-way liquid inlet valve 601 and the one-way liquid discharge valve 701 are provided on the liquid outlet pipe 6 and the injection pipe 7. When the first piston rod 18 moves toward the end away from the one-way liquid inlet valve 601, the interior of the first piston cylinder 5 near the one-way liquid inlet valve 601 is in a negative pressure state, and the one-way liquid inlet valve 601 is closed. 01 is in the open state, and the one-way drain valve 701 is in the closed state, so that the first piston rod 18 can quantitatively extract the coolant inside the cooling box 4 into the interior of the first piston cylinder 5 through the liquid outlet pipe 6. When the first piston rod 18 is reset toward the end close to the one-way liquid inlet valve 601, the internal air pressure of the first piston cylinder 5 close to the one-way liquid inlet valve 601 is in a positive pressure state, and the one-way liquid inlet valve 601 is in the closed state, and the one-way drain valve 701 is in the open state, so that the first piston rod 18 can inject the coolant inside the first piston cylinder 5 into the circulation pipe 3 through the injection pipe 7 for circulation.

[0038] As the temperature inside the box body 1 rises, and the fixed block 17 moves horizontally toward the end close to the pressure sensor 22, the eccentric block 20 moves under the action of the fixed block 17 and the eccentric position of the circular plate 14 increases, so that the eccentric block 20 will push the first piston rod 18 to increase the moving stroke, further increasing the first piston rod 18's extraction and discharge amount of the coolant inside the circular plate 14, and then the flow rate of the coolant inside the circulation pipe 3 increases synchronously, further improving the cooling effect on the server.

[0039] As the temperature inside the box 1 decreases, the above-mentioned structure will synchronously reset and move in the opposite direction, and the movement stroke of the first piston rod 18 will decrease, and the flow rate and flow of the coolant will also decrease accordingly, thereby saving energy. Through the coordinated use of the above-mentioned structure, the flow rate and flow of the coolant can be dynamically adjusted according to the actual operating temperature of the cluster server, ensuring that the server can maintain the best cooling effect under different load conditions, effectively solving the problem that the flow rate and flow of the traditional cooling system are fixed and cannot be automatically adjusted according to temperature changes, and significantly improving the adaptability and efficiency of the cooling system.
