Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer equipment cooling, further relates to a cooling liquid circulation system of an intelligent computing all-in-one machine, and more particularly relates to a redundant safety control method of an intelligent computing all-in-one machine. BACKGROUND

[0002] In recent years, with the rapid development of artificial intelligence technology and the continuous progress of hardware technology, various general-purpose large models and vertical field models have developed rapidly, and more and more people have begun to use various large models to improve work efficiency or empower business development in their respective fields. However, with the rapid development of AI technology, data security and intellectual property protection problems are becoming more and more serious. After data is uploaded to the cloud server, during the use of the large model, it may cause the leakage of enterprise or personal data and the risk of related intellectual property infringement. Therefore, more and more customers hope to be able to deploy large models that belong to their own enterprise or individual on the local. By deploying locally, the risk of data loss, commercial secret leakage and intellectual property infringement can be significantly reduced. Under such a development trend, the demand for all-in-one machines suitable for enterprise or individual customers is becoming more and more intense.

[0003] However, such all-in-one machines usually require both certain response and computing power and not too large size, especially for some scientific research institutions or small and medium-sized enterprises, it is necessary to balance the relationship between cost and computing power response. Therefore, it is necessary to improve the computing power of the all-in-one machine as much as possible within the range of as small as possible size, which naturally increases the requirement for the power density of the all-in-one machine, thereby bringing the problem of heat dissipation of electronic components. The traditional air cooling heat dissipation method has been difficult to meet its heat dissipation demand, which is easy to cause the temperature of the equipment to be too high, thereby affecting the performance and stability of the equipment, and even shortening the service life of the equipment. Although the cold plate type liquid cooling can improve the heat dissipation efficiency, it relies on the direct contact of the metal cold plate with the heat generating components, and needs a complex pipeline system to realize the circulation of the cooling liquid, which increases the equipment volume and maintenance complexity. For example, the CDU (cooling distribution unit) and pipeline of the cold plate type liquid cooling system account for more than 60% of the overall cost, and need to be disassembled during maintenance, which affects the business continuity. In addition, the cold plate type liquid cooling cannot solve the problem of global heat dissipation, and local hot spots may still cause the chip to reduce the frequency.

[0004] Submersion cooling is feasible for all-in-one machine, however, there are still many problems to be solved in current submersion cooling system. For example, most of the machines still need to be externally provided with CDU and corresponding secondary side heat exchange device, so that the whole machine has large volume and occupies large area, which is not suitable for flexible movement or arrangement; or the flow design of the cooling liquid in the machine is unreasonable, the circulation flow speed or efficiency is low, which easily leads to local insufficient heat dissipation of the core heat generating elements (such as GPU) with large heat generation, and affects the operation efficiency; or the cooling system working process is relatively simple, and when the cooling liquid leaks or the circulation system fails, no standby cooling scheme is designed, and the core heat generating elements fail due to insufficient heat dissipation; or the machine has no corresponding expansion capability after installation, and cannot meet the subsequent demand for improving computing power.

[0015] The application further provides a redundant safety control method of the smart computing all-in-one machine, which comprises the following steps:

[0016] S1: When the temperature value T detected by the first temperature sensor exceeds the preset threshold T1, it indicates that the heat dissipation of the internal elements of the containing cavity is insufficient;

[0017] S2: Further calculate the pressure difference AT between the first pressure sensor and the second pressure sensor, and determine whether it is within the preset pressure difference range; if yes, it proves that the radiator does not occur blockage or leakage and executes step S3; if no, it prompts that the radiator has a fault;

[0022] Based on the above invention content, the cooling intelligent computer cooling liquid circulating system and the redundant safety control method have the following advantages:

[0023] By body layer integration, the upper accommodating cavity accommodates functional components on the working side, such as GPU, CPU, power module and the like, and the lower mechanical bin accommodates mechanical components, such as circulating pump, dry cooling radiator, fan and the like. Compared with the traditional CDU external distributed liquid cooling equipment, the volume is greatly reduced, the floor area is reduced, the flexible transportation is facilitated, and the application scenarios of the equipment are expanded. The liquid cooling and air cooling are cooperated, the heating elements are cooled by the cooling liquid direct contact heat exchange structure, the cooling liquid is cooled by the circulating pump and fan with adjustable operating frequency, the operating power can be flexibly adjusted according to the cooling requirement, the cooling requirement is met, and the energy consumption of the equipment is reduced.

[0025] By optimizing and adjusting the circulating flow path of the cooling liquid, the flow of the cooling liquid is more in line with the cooling requirement and more flexible through the design of the three-way valve, the liquid distributor, the branch pipeline, the partition plate in the accommodating cavity and the opening hole. The liquid distributor and the branch pipeline can improve the stability and uniformity of the liquid flow, and improve the uniformity of the fluid field and the temperature field in the accommodating cavity.

[0026] The design of the three-way valve and the partition of the accommodating cavity makes the cooling liquid have multiple circulating flow schemes, which can guarantee the cooling requirement of the core heating element in the case that the cooling system may fail, does not affect the safe operation of the intelligent algorithm all-in-one machine, and improves the long-term operation stability. The cooling liquid flows out from the area where the core heating element is located, which can strengthen the heat dissipation of the area and ensure the operation of the core heating element.

[0027] By setting one or more rotating leaves in the accommodating cavity, the heat exchange efficiency of the cooling liquid can be rapidly increased in a short time to meet the cooling requirement of the functional components under different loads.

[0028] The GPU module and the pump body and the like core components are supported to be plugged and replaced, the maintenance time is shortened from ≥40 minutes of the traditional scheme to ≤5 minutes; the accommodating cavity is provided with an expansion slot and a backup opening hole, which can improve the expansion capacity of the intelligent algorithm all-in-one machine and ensure the cooling capacity after expansion.

[0029] By setting multiple temperature sensors and pressure sensors and combining with a control algorithm, the operating state of the cooling liquid circulating system can be monitored in real time, and when the cooling is insufficient, the fault reason is identified, the operating state of each component is timely and reasonably adjusted, and the safety redundancy of the system is improved.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, and for those skilled in the art, all other embodiments obtained based on the embodiments of the present application without any creative effort belong to the protection scope of the present application.

[0038] Figure 1 As a perspective view of the intelligent computing all-in-one machine of the present application, the intelligent computing all-in-one machine adopts immersion cooling, including a shell 1, a top cover 2, a heat dissipation window 3, an observation window 4, a display screen 5, a handle 6, a navigation interface group 7, a support foot 8, and a mechanical bin 9, etc. The shell 1 and the top cover 2 define a containing space for functional components of the intelligent computing all-in-one machine, and the support foot 8 at the bottom of the shell 1 has a stabilizing support function. The heat dissipation window 3 is below the front of the shell 1, and the observation window 4 for the user to directly observe the working components in the containing space, especially the running state of the GPU, is at the upper left position. The display screen 5 above the observation window 4 displays the working state of the display system, which can have a customized UI interface and a touch function to meet the user's needs for control, operation, statistics, and display of various parameters or running modes of the all-in-one machine, and can also display important alarm information (such as insufficient liquid level and pump body over-temperature), while supporting sound and light alarms (≥85 dB buzzer), and can be connected with a controller (not shown) to support real-time retrieval of running parameters of the intelligent all-in-one machine (such as temperature, power consumption, network delay, etc.), and generate a heat dissipation efficiency curve. The handles 6 on both sides can be used to move the all-in-one machine, suitable for moving in different edge side occasions, improving the flexibility and expandability of the equipment. The navigation interface group 7 integrates industrial-grade I / O expansion interfaces (2x RJ45, 1x USB 3.0), power modules (navigation plug power modules, switch modules), and display modules (VGA J interface, etc.) to support multi-device collaboration and low-latency data transmission (end-to-end delay ≤15 ms). The mechanical bin 9 is provided with a circulating pump 11 for driving the circulation of the cooling liquid and related pipelines (covered by a cover plate and cannot be seen at the moment, which will be described in detail later).

[0039] As shown in Figure 2 , it is the first explosion view of the intelligent computing all-in-one machine of the present application. As can be seen from Figure 2 , there is a containing cavity 10 inside the shell 1, and the core working components of the intelligent computing all-in-one machine (including CPU, GPU, storage module, communication module, etc.) are placed inside the containing cavity 10. The cooling liquid is also mainly contained in the containing cavity 10 to cool the core working components, and each side of the containing cavity has a cooling liquid circulation pipe (this is only a schematic and not the actual cooling liquid pipe design of the present application, please refer to the detailed description later), which is connected with the radiator (not shown yet) and the circulating pump 11 inside the mechanical bin 9 to form a cooling liquid circulation loop to realize the circulation flow of the cooling liquid.

[0040] Figure 3This is a second exploded view of the intelligent computing all-in-one computer of the present invention. This view clearly shows the circulation pump 11, the radiator 12 located within the heat dissipation window 3 below the housing 1, and the first fan 13 that drives the heat dissipation medium (e.g., air) to flow horizontally through the radiator 12. The radiator 12 is also provided with a radiator inlet pipe 14 connected to the coolant return pipe and a radiator outlet pipe 15 connected to the return port of the circulation pump 11.

[0041] Figure 4 Schematic diagram of the cooling liquid circulation system of the intelligent computing machine of the present invention. Figure 4 As shown, the upper portion contains the intelligent computing unit's housing 10, while the lower portion houses the mechanical compartment 9. The mechanical compartment 9 is divided into two sections by a partition 91. The upper section houses the radiator 12 and a first fan 13 located behind the radiator 12, while the lower section houses the circulation pump 11. Furthermore, a second fan 16 can be provided in the lower section, and first ventilation holes 17 are provided on both sides of the lower portion of the housing 1 (i.e., below the two sides of the mechanical compartment 9). Multiple second ventilation holes 18 can also be provided on the partition 91. The second fan 16 directs external air through the lower portion of the mechanical compartment 9 and, through the second ventilation holes 18, directs external air upward through the radiator 12, further enhancing its heat dissipation efficiency. Furthermore, the start / stop and power levels of the first and second fans 13, 16 can be appropriately configured to guide air along the desired path according to different cooling requirements or operating modes. For example, in normal mode, the power of the first fan 13 is higher than that of the second fan 16, so that air is drawn from the first ventilation hole 17 into the part below the mechanical compartment 9 and flows upward through the second ventilation hole 18 to the radiator 12, so that more external air flows through the radiator 12 to increase its heat dissipation capacity; when the heat dissipation demand is small, in low power mode, the operating power of the first fan 13 can also be turned off or reduced. When it is turned off or is less than the operating power of the second fan 16, air is drawn through the radiator 12 and downward through the second ventilation hole 18 into the part below the mechanical compartment 9 and flows out from the first ventilation holes 17 on both sides, thereby increasing the air flow speed and reducing energy consumption. Such a spatial heat dissipation arrangement makes the heat dissipation of the intelligent all-in-one machine more flexible, has stronger heat dissipation capacity and can reduce energy consumption. Therefore, the intelligent computing all-in-one machine of the present invention can meet the heat dissipation requirements of the design without the need for an external CDU and secondary side heat dissipation device, thereby reducing the size and footprint of the all-in-one machine and being able to be flexibly moved to meet the needs of different scenarios.

[0042] Refer to the following Figure 4 , the cooling cycle system is further explained. Figure 4The cooling circulating system comprises a circulating pump 11, a liquid feeding main pipe 21, a three-way valve 22, a first liquid feeding branch pipe 23, a second liquid feeding branch pipe 24, a first liquid distributor 25 and a second liquid distributor 26. The circulating pump 11 is connected with the liquid feeding main pipe 21, the liquid feeding main pipe 21 is connected with the three-way valve 22, one port of the three-way valve 22 is communicated with the first liquid feeding branch pipe 23, and the other port is communicated with the second liquid feeding branch pipe 24. The first liquid feeding branch pipe 23 extends vertically upward to the right side above the containing cavity 10 and is connected with the first liquid distributor 25. The first liquid distributor 25 is fixedly connected with a plurality of corresponding first opening holes 28 arranged on the upper cover plate 92 of the containing cavity 10 through a plurality of first branch pipes 27, so as to provide cooling liquid to the right side of the containing cavity 10 through the plurality of first branch pipes 27. A vertical partition plate 29 is arranged in the containing cavity 10, the upper part of the vertical partition plate 29 is fixedly connected with the upper cover plate 92 of the containing cavity 10, and the lower part of the vertical partition plate 29 has a gap 30 with the lower bottom plate 93 of the containing cavity 10. The gap 30 forms a flow channel of the cooling liquid, and the first containing space 31 and the second containing space 32 separated by the vertical partition plate 29 are communicated. The first containing space 31 is located on the left side of the containing cavity 10, and the second containing space 32 is located on the right side of the containing cavity 10. The plurality of first opening holes 28 are actually arranged on the side of the upper cover plate 92 corresponding to the second containing space 32, that is, the cooling liquid delivered through the plurality of first branch pipes 27 flows into the second containing space 32 rather than the first containing space 31. The second liquid feeding branch pipe 24 extends horizontally leftward at the position of the three-way valve 22 and is connected with the second liquid distributor 26. The second liquid distributor 26 is fixedly connected with a plurality of corresponding second opening holes 34 arranged on the lower bottom plate 93 of the containing cavity 10 through a plurality of second branch pipes 33. The plurality of second opening holes 34 are arranged on the side of the lower bottom plate 93 corresponding to the first containing space 31, so as to provide cooling liquid to the first containing space 31 on the left side of the containing cavity 10 through the plurality of second branch pipes 33. Through the above-mentioned liquid feeding structure design and the division of the containing cavity 10, the regional separate liquid feeding can be realized, that is, the cooling liquid is selected to be delivered to the first containing space 31 and / or the second containing space 32 according to needs to meet different heat dissipation requirements.

[0043] Meanwhile, with the help of the gap 30 below the vertical partition plate 29, the cooling liquid in the second containing space 32 can be pushed to flow to the first containing space 31 through the gap 30 due to the inflow of the cooling liquid from above the second containing space 32. A plurality of third open holes 35 are arranged on the side of the upper cover plate 92 corresponding to the first containing space 31, and a plurality of return liquid branch pipes 36 are fixedly connected to the plurality of third open holes 35 correspondingly, and the plurality of return liquid branch pipes 36 converge to a liquid collector 37, and the other end of the liquid collector 37 is connected with a return liquid main pipe 38. The return liquid main pipe 38 extends downward and is connected with the radiator liquid inlet pipe 14, so that the cooling liquid returns to the inside of the radiator 12 for heat exchange. The radiator 12 makes the external air flow through the radiator 12 in the horizontal direction by the rotation of the first fan 13, exchanges heat with the cooling liquid in the heat exchange pipe of the radiator 12, and cools the cooling liquid, and the cooled cooling liquid is connected with the return liquid port of the circulating pump 11 through the radiator liquid outlet pipe 15, so as to realize the cooling and return of the cooling liquid. The cooling liquid flows upward in the first containing space 31 from the second open hole 34 on the lower bottom plate 93 and exits the first containing space 31 from the third open hole 35.

[0044] The radiator 12 can adopt a micro-channel heat exchanger, and according to the size of the intelligent computer and the heat dissipation requirement, a single-row, double-row or multi-row structure or an A-shaped design can be adopted to maximize the contact area with the air to strengthen the heat exchange. Alternatively, a plurality of partitions can be arranged in the header of the micro-channel heat exchanger to make the cooling liquid flow through each micro-channel as evenly as possible to improve the heat dissipation efficiency. The circulating pump 11 is a controllable and adjustable electric water pump, which can work continuously or intermittently and is equipped with self-diagnosis and fault feedback functions. Alternatively, the circulating pump 11 is a centrifugal pump driven by a brushless DC motor. The first fan 13 and the second fan 16 are both axial flow fans, and they can realize frequency conversion adjustment, so as to adapt to different heat exchange requirements.

[0045] In the following, with reference to Figure 4The working process of the cooling liquid circulation system of the intelligent computing all-in-one machine is described. The cooling liquid is pressurized by the circulating pump 11 and flows into the liquid delivery main pipe 21, and then enters the three-way valve 22. The three-way valve 22 divides the cooling liquid into two branches. The cooling liquid entering the first liquid delivery branch pipe 23 flows upward into the first liquid distributor 25, and then enters a plurality of first branch pipes 27 and passes through a plurality of corresponding first opening holes 28 on the upper cover plate 92 into the second containing space 32 of the containing cavity 10. The cooling liquid flows downward in the second containing space 32 and passes through a plurality of non-core heat generating elements 40, exchanges heat with the heat exchange structure on the plurality of non-core heat generating elements 40, thereby reducing the temperature of the non-core heat generating elements 40. The cooling liquid then enters the first containing space 31 through the gap 30 below the vertical partition plate 29. The cooling liquid entering the second liquid delivery branch pipe 24 through the three-way valve 22 flows horizontally into the second liquid distributor 26, and then enters a plurality of second branch pipes 33 and passes through a plurality of corresponding second opening holes 34 into the first containing space 31. The cooling liquid is combined with the cooling liquid from the second containing space 32 and then flows upward through a plurality of core heat generating elements 41, exchanges heat with the heat exchange structure on the plurality of core heat generating elements 41, thereby reducing the temperature of the core heat generating elements 41. The plurality of core heat generating elements 41 can adopt a copper fin direct contact heat exchange structure (thermal conductivity ≥ 400 W / m·K), and the plurality of non-core heat generating elements 40 can adopt an aluminum fin direct contact heat exchange structure. The cooling liquid exchanges heat and then enters a plurality of corresponding return liquid branch pipes 36 through a plurality of third opening holes 35 on the upper cover plate 92 of the containing cavity 10, and then converges to the liquid collector 37. The cooling liquid flowing out of the liquid collector 37 enters the return liquid main pipe 38, and then flows into the liquid inlet pipe 14 of the radiator 12 and flows through the liquid microchannel in the radiator 12. After heat exchange and cooling with external air, the cooling liquid flows out of the liquid outlet pipe 15 of the radiator and returns to the circulating pump 11, thereby completing the circulation and heat dissipation flow of the cooling liquid.

[0046] According to the intelligent computing all-in-one machine of the present application, a plurality of spare slots 50 are provided beside the core heat generating elements 41 already installed in the containing cavity 10, and new core heat generating elements (such as GPU elements) can be inserted as needed. Therefore, a plurality of spare opening holes 51 corresponding to the plurality of spare slots 50 are also provided on the upper cover plate 92 of the containing cavity 10, so that after the core heat generating elements 41 are increased, the spare opening holes 51 can be opened as needed to meet the needs of cooling liquid heat dissipation and flow. In addition, one or more rotating vanes 52 are installed below the plurality of core heat generating elements 41 inside the first containing space 31, which are opened and operated when needed to accelerate the flow of cooling liquid inside the first containing space 31 and enhance the heat exchange between the cooling liquid and the plurality of core heat generating elements 41. The rotating vanes 52 have a control module and are driven by a variable frequency motor to achieve variable frequency regulation.

[0047] According to the intelligent computer of the present application, the first temperature sensor 60 and the first pressure sensor 61 are arranged on the radiator inlet pipe 14 to monitor the temperature and pressure of the cooling liquid flowing into the radiator 12, the second temperature sensor 62 and the second pressure sensor 63 are arranged on the radiator outlet pipe 15 to monitor the temperature and pressure of the cooling liquid flowing out of the radiator 12, the third pressure sensor 64 is arranged on the upper cover plate 92 to monitor the pressure inside the containing cavity 10, and a pressure relief valve 65 is further arranged to perform safe pressure relief when the pressure exceeds a preset safety threshold. In addition, a liquid filling port (not shown) can also be arranged on the upper cover plate 92 to perform cooling liquid filling and emptying (connected to a suction pump) when it is necessary to replace or supplement the cooling liquid. Of course, a detachable joint can also be connected between the liquid return main pipe 38 and the radiator inlet pipe 14, and the cooling liquid can be filled or emptied through the liquid return main pipe 38.

[0048] The cooling liquid circulating system of the intelligent computer of the present application is further provided with a controller (not shown) which is in communication connection with the first temperature sensor 60, the first pressure sensor 61, the second temperature sensor 62, the second pressure sensor 63, the third temperature sensor 64, the control module of the circulating pump 11, the control modules of the first fan 13 and the second fan 16, the control module of the rotary vane 52, and the three-way valve 22.

[0049] Next, the redundant safety control method of the cooling liquid circulating system of the present application will be described in detail.

[0050] S1: When it is monitored that the temperature value T detected by the first temperature sensor 60 exceeds the preset threshold T1, it indicates that the internal elements of the containing cavity 10 are insufficiently cooled.

[0051] S2: The pressure difference AT between the first pressure sensor 61 and the second pressure sensor 63 is further calculated to determine whether it is within the preset pressure difference range; if yes, it proves that the radiator 12 does not have blockage or leakage and step S3 is executed; if no, it indicates that the radiator 12 has a fault.

[0052] S3: The rotation speed and / or current of the first fan 13 and the circulating pump 11 are detected to determine whether they are within the set range; if yes, step S4 is executed; if no, it indicates that the first fan 13 and / or the circulating pump 11 has a fault.

[0053] S4: The rotation speed of the circulating pump 11 is increased and the rotation speed of the first fan 13 is simultaneously increased (because the cooling liquid circulation is accelerated, the cooling liquid flowing through the radiator 12 is increased, and the rotation speed of the first fan 12 needs to be simultaneously increased), and after running for a first predetermined time t1, it is determined whether the temperature value T detected by the first temperature sensor 60 is still greater than the first preset threshold T1; if yes, step S5 is executed; if no, the redundant safety control is ended.

[0054] S5: control the three-way valve 22 to gradually reduce the amount of cooling liquid delivered to the first liquid delivery branch pipe 23, gradually increase the amount of cooling liquid delivered to the second liquid delivery branch pipe 24, and make more cooling liquid from the circulating pump 11 directly flow into the first containing space 31 and flow upward through the plurality of core heat generating elements 41 to cool them; after running for a second predetermined time t2, determine whether the temperature value T detected by the first temperature sensor 60 is still greater than the first preset threshold T1; if yes, execute step S6; if no, end the redundant safety control;

[0055] S6: further open one or more rotary vanes 52 to speed up the flow of cooling liquid in the first containing space 31 to enhance heat exchange; after running for a third preset time t3, determine whether the temperature value T detected by the first temperature sensor 60 is still greater than the first preset threshold T1; if yes, prompt that the cooling liquid is failed and needs to be replaced; if no, end the redundant safety control.

[0056] The first preset threshold T1 can be calculated by a large model according to various parameters such as ambient temperature, ambient humidity, cooling liquid type, cooling liquid performance, core heat generating element type and / or quantity, or can be pre-set at the factory.

[0057] Through the above redundant safety control method, the operating state of the cooling liquid circulation system can be monitored in real time, and when insufficient heat dissipation occurs, the fault cause can be identified, and the operating state of each component can be adjusted in a timely and reasonable manner, thereby improving the safety redundancy of the system.
