Coolant corrosion performance is a key factor affecting the reliability, lifespan, and stability of liquid-cooled servers, making it a crucial component of this testing process.

[0003] The test equipment used in related technologies for testing the corrosion performance of coolants is insufficient in comprehensively verifying the corrosion performance of coolants. This type of test equipment cannot simulate the complex working conditions in a real working environment, resulting in deviations between the test results and the actual situation, and the test results are unreliable. Summary of the Invention

[0023] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0025] As data centers evolve, data and computing power are growing exponentially. Air-cooled servers are no longer able to meet the heat dissipation requirements, and the thermal power consumption required for computing has essentially reached the limits of air cooling. Therefore, liquid-cooled servers have become the mainstream server type in the market, offering unparalleled advantages over air-cooled servers in terms of reduced energy consumption and heat dissipation efficiency.

[0026] Liquid-cooled servers typically dissipate heat by placing a cold plate in contact with the heat source. The cold plate absorbs heat from the source, while the secondary system dissipates the heat from the cold plate through the circulation of a coolant (such as deionized water). In actual operation, the coolant does not maintain a constant state but is affected by various factors, such as pH fluctuations, microbial growth, and increased levels of impurity ions. These factors can cause corrosion of components in the liquid cooling system (such as the cold plate). Liquid-cooled servers face numerous challenges in actual operation, and water corrosion is a key factor affecting the reliability and lifespan of liquid cooling systems.

[0027] To maintain the long-term stability and reliability of liquid-cooled servers, the coolant must possess excellent thermal conductivity, chemical stability, and compatibility with system materials. Therefore, coolants typically use liquids with stable physical and chemical properties, such as deionized water, electronic fluorinated fluid, mineral oil, and silicone oil. As liquid-cooled servers cycle under actual operating conditions, the coolant will gradually develop corrosive properties due to the influence of these factors. To ensure the normal operation of liquid-cooled servers, prevent the possibility of corrosion risks in liquid-cooled servers, predict the time when corrosion risks will occur to reduce corrosion risks, guide the design, production, and maintenance of liquid-cooled servers, and reduce maintenance costs, it is generally necessary to test and verify the corrosion properties of the coolant in liquid-cooled servers.

[0028] At present, there are roughly two types of test equipment used for coolant corrosion performance testing in related technologies. One type mainly completes the test of the heat dissipation performance and operating efficiency of the liquid cooling system. This type of equipment rarely pays attention to the test of the coolant corrosion performance. The other type of equipment can realize the test of the coolant corrosion performance, but cannot simulate the actual working conditions of the liquid-cooled server. For example, this type of equipment uses a constant temperature or flow test method, etc., and cannot simulate the flow fluctuations and temperature fluctuations in the actual working conditions. For another example, this type of equipment has conducted a lot of research on the chemical stability of the coolant and its compatibility with system materials, and most of them can only complete static testing or testing and evaluation under single conditions.

[0029] Therefore, the test equipment used in the relevant technology for testing the corrosion performance of coolants is insufficient in verifying the comprehensiveness of the corrosion performance of coolants. This type of test equipment cannot simulate the complex working conditions in the real working environment, resulting in deviations between the test results and the actual situation, and the test results are unreliable.

[0030] Based on the above facts and current situation, an embodiment of the present application provides a corrosion cycle test device, which can simulate the actual working conditions of the liquid-cooled server by precisely controlling the changes in various test conditions. At the same time, the corrosion cycle test device can perform comprehensive verification of the entire cold plate in the liquid-cooled server, thereby achieving the purpose of verifying the entire cold plate under simulated actual working conditions, and can comprehensively evaluate the corrosion resistance of the cold plate, so that the test results are more in line with the actual situation.

[0031] To this end, the embodiment of the present application needs to first simulate the circulation of the coolant. On the basis of realizing the circulation of the coolant, the flow rate, temperature, etc. of the coolant are controlled by setting relevant control components, and then the entire cold plate is connected to the circulation path of the coolant. By reasonably setting the flow fluctuation and temperature fluctuation of the coolant and allowing the coolant to circulate in the cold plate, the real working conditions can be simulated. Then, by setting a monitoring component that can monitor the changes in the coolant in real time, the basic type of corrosion cycle test device can be formed. The corrosion cycle test device can truly simulate the circulation corrosion process of the coolant, thereby obtaining accurate test results.

[0032] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0033] Figure 1 Schematic diagram of the principle of the corrosion cycle experimental device provided in the embodiment of the present application. Figure 2 This is a schematic diagram of the structure of the liquid detection component provided in an embodiment of the present application.

[0034] In the examples of this application, please refer to Figure 1 and Figure 2 The corrosion cycle test device includes a coolant circulation system 100, a flow control component 200, a temperature control component 300, a liquid monitoring component 400 and a control system.

[0035] The coolant circulation system 100 is used to circulate the coolant. It requires a coolant supply device and necessary power components, which circulate the coolant. The cold plate 10 in a liquid-cooled server can be connected to the coolant circulation system 100, and the coolant circulates through the cold plate 10 under the action of the power components.

[0036] It should be noted that the cold plate 10 in the embodiment of the present application is connected as a whole to the circulation path of the coolant, so that the various complex structures and multiple materials of the cold plate 10 can interact with the coolant, thereby enabling the cold plate 10 as a whole to complete verification in the circulation flow of the coolant.

[0037] The coolant circulation system 100 can be an independent circulation system. For example, the coolant can flow back and forth between the coolant supply device and the cold plate 10. After a verification cycle is completed, the next verification can be achieved by replacing the coolant. Of course, in other embodiments, the coolant supply device can be replaced so that the next verification can be achieved by replacing the coolant supply device. Of course, in other embodiments, to avoid residual coolant affecting the next verification, the residual coolant can be flushed with new coolant before the next verification.

[0038] The flow control component 200 is disposed in the coolant circulation system 100 and is used to control the flow rate of the coolant. The flow control component 200 is one of the aforementioned control components, and its purpose is to control the flow rate to simulate the effect of the flow rate factor on the corrosion performance of the coolant. It is understood that the flow control of the flow control component 200 can be pre-set based on the actual operating conditions of the liquid-cooled server. When the corrosion cycle test device starts working, the pre-set flow change signal is transmitted to the flow control component 200. Therefore, the flow control component 200 has a controllable function. For example, the flow rate can be controlled by setting a controllable valve.

[0039] The temperature control assembly 300 is used to exchange heat with the cold plate 10 and control the temperature changes of the coolant. This temperature control assembly 300 is a type of the aforementioned control assembly, and its purpose is to control temperature to simulate the impact of temperature fluctuations on the corrosive properties of the coolant. It is understood that the temperature control assembly 300 can be pre-configured based on the heat source of the cold plate 10, with a heating temperature curve preset according to the heating characteristics of the heat source. The pre-set temperature change signal is then transmitted to the temperature control assembly 300. Therefore, the temperature control assembly 300 can meet the requirement of raising the temperature to a level that matches the heating characteristics of the heat source when necessary.

[0040] The above-mentioned flow control component 200 and temperature control component 300 are basic types of control components in the corrosion cycle test device. In other embodiments, control components that can control factors such as pressure can also be set. These control components realize the control of basic test conditions in order to truly simulate the actual working conditions of the liquid-cooled server.

[0041] The liquid monitoring component 400 is disposed in the coolant circulation system 100 and is used to monitor changes in the parameters of the coolant in real time. The liquid monitoring component 400 can obtain changes in the coolant in real time. It can detect the physical and chemical properties of the coolant, thereby obtaining changes in the corrosiveness of the coolant, which can reflect the corrosion of the cold plate 10. In conjunction with the following embodiments, it can be seen that the liquid monitoring component 400 can monitor parameters such as pH, turbidity, conductivity, total iron, total copper, and total hardness of the coolant. These parameters are the parameter indicators that the liquid monitoring component 400 needs to monitor.

[0042] On the basis of the above-mentioned ability to truly simulate the actual working conditions of the liquid-cooled server, the setting of the liquid monitoring component 400 can obtain the corrosion changes of the coolant in real time. The corrosion changes can reflect the corrosion conditions of the cold plate 10, thereby achieving comprehensive and true verification of the corrosion resistance of the cold plate 10. The results are reliable and can serve as a scientific basis for the design, development and maintenance of liquid-cooled servers.

[0043] The control system is the control core of the corrosion cycle test device. The coolant circulation system 100, flow control component 200, temperature control component 300, and liquid monitoring component 400 can be connected to the control system by signal to accept the control system's control. For example, the control system can control the opening and closing of the coolant circulation system 100, the opening and closing of the valve in the flow control component 200, the temperature rise in the temperature control component 300, and the collection of various parameter indicators by the liquid monitoring component 400. In short, the embodiment of the present application can improve the automation and accuracy of the corrosion cycle test device by setting up a control system, reduce operational errors, improve efficiency, and reduce the operation and maintenance costs of the corrosion cycle test device.

[0044] It is understandable that the control system can store control programs for controlling other components. The control programs can be, for example, flow change programs, temperature change programs, etc. By starting these programs through the control system, the above-mentioned flow fluctuations and temperature fluctuations can be simulated.

[0045] In the embodiment of the present application, the coolant circulation system 100 can simulate the circulation environment of the cold plate 10 under actual working conditions, the flow control component 200 can simulate the flow fluctuation of the cold plate 10 under actual working conditions by changing the flow rate, and the temperature control component 300 can simulate the temperature fluctuation of the cold plate 10 under actual working conditions by changing the temperature, thereby achieving the purpose of simulating the actual working conditions of the liquid-cooled server by controlling the basic test conditions. During the circulation of the coolant, the liquid monitoring component 400 can reflect the corrosion changes of the coolant in real time, thereby obtaining the corrosion condition of the cold plate 10, and because the cold plate 10 is connected as a whole in the coolant circulation system 100, supplemented by the automatic control of the control system, it can accurately, timely and efficiently complete the verification of the corrosion performance of the coolant, and can comprehensively evaluate the corrosion resistance of the cold plate 10, so that the test results are more in line with the actual situation.

[0046] In some embodiments, please refer to Figure 1 The coolant circulation system 100 includes a liquid storage part 110, a circulation pipeline 120 and a circulation power part 130. The liquid storage part 110 is used to store coolant. The circulation pipeline 120 is connected between the liquid outlet 111 and the liquid return port 112 of the liquid storage part 110. The circulation power part 130 is arranged on the circulation pipeline 120 and is used to drive the coolant to circulate between the circulation pipeline 120 and the liquid storage part 110. The cold plate 10 is connected to the circulation pipeline 120.

[0047] The liquid storage member 110 can be configured as a can or box. For example, the liquid storage member 110 can be a liquid storage tank. The coolant stored in the liquid storage member 110 should be sufficient to complete the verification of the coolant's corrosion performance. The liquid storage member 110 can be made of corrosion-resistant materials, such as stainless steel, to ensure the long-term stability of the liquid storage member 110 in corrosive environments.

[0048] The circulation pipeline 120 is usually formed of a corrosion-resistant pipe structure. For example, these pipes can be made of corrosion-resistant materials such as stainless steel, and of course can also be made of polymer materials.

[0049] It should be noted that for the liquid storage part 110 and the circulation pipeline 120, the materials used need to have a certain degree of compatibility with the coolant. These materials should be as unaffected by the coolant as possible, so as to avoid the coolant interfering with the corrosion performance of the cold plate 10 and improve the accuracy of the verification results of the corrosion performance of the coolant.

[0050] The circulating power component 130 may be a liquid pump or the like. It is understandable that a liquid pump is provided on the circulating pipeline 120 , and the liquid pump can generate a driving force to realize the circulating flow of the coolant on the circulating pipeline 120 .

[0051] As can be seen, when the control system activates the circulating power element 130, the coolant begins to circulate in the circulation pipeline 120. When the control system deactivates the circulating power element 130, the coolant's circulation is terminated. During the coolant's circulation, the control system's control of the circulating power element 130 enables the coolant to circulate in the circulation pipeline 120.

[0052] In some embodiments, please refer to Figure 1 The coolant circulation system 100 further includes a first manual valve 140 and a second manual valve 150 , which are disposed on the circulation pipeline 120 , and the circulation power member 130 is detachably connected between the first manual valve 140 and the second manual valve 150 .

[0053] It can be understood that the first manual valve 140 and the second manual valve 150 are valve bodies that can be opened and closed manually. After the first manual valve 140 and the second manual valve 150 are fully opened, the coolant can flow on the circulation pipeline 120, and if any one of the manual valves is closed, the coolant cannot flow.

[0054] The purpose of providing the first manual valve 140 and the second manual valve 150 is mainly reflected in two aspects. First, by providing two manual valves, the flow and cutoff of the coolant can be better controlled, which can ensure the safe on-off of the circulation pipeline 120. Second, by arranging the circulation power component 130 between the first manual valve 140 and the second manual valve 150, the circulation power component 130 can be easily removed from the circulation pipeline 120, thereby facilitating the replacement or maintenance of the circulation power component 130. It is understood that the first manual valve 140 and the second manual valve 150 can also be made of corrosion-resistant materials, such as stainless steel, and the specific structure of the manual valve can be designed with reference to the shut-off valve in the relevant art.

[0055] In some specific embodiments, the first manual valve 140 , the circulation power valve, and the second manual valve 150 may be sequentially arranged on the circulation pipeline 120 connected to the liquid outlet 111 .

[0056] In some embodiments, please refer to Figure 1 The coolant circulation system 100 further includes a one-way check valve 160 , which is disposed on the circulation pipeline 120 to allow the coolant to flow from the liquid outlet 111 to the liquid return port 112 .

[0057] The setting of the one-way check valve 160 ensures that the coolant can only enter the cold plate 10 along the circulation pipeline 120 from the liquid outlet 111 of the liquid storage component 110 and then flow back to the liquid storage component 110 through the return liquid port 112. The one-way check valve 160 can prevent the coolant from flowing back on the circulation pipeline 120, ensure the one-way flow of the coolant, avoid damage to the corrosion cycle test device or inaccurate test results due to backflow, and improve the safety of the corrosion cycle test device.

[0058] In some specific embodiments, the one-way check valve may be arranged on the circulation pipeline 120 between the circulating power component 130 and the cold plate 10 .

[0059] In some embodiments, please refer to Figure 1 The flow control component 200 includes a solenoid valve 210, which is arranged on the circulation pipeline 120. Furthermore, the solenoid valve 210 can select a proportional valve or a micro solenoid valve 210, etc. The solenoid valve 210 can be controlled by the control system, so that after the control system runs the relevant program, the opening and closing degree of the solenoid valve 210 changes, thereby forming different flow rates and forming the flow fluctuation required by the corrosion cycle test device.

[0060] In some embodiments, the flow control assembly 200 further includes a flow sensor 220 , which is disposed on the circulation line 120 and is used to monitor the flow of the coolant.

[0061] The flow sensor 220 can be set on the circulation pipeline 120 between the return liquid port 112 and the cold plate 10. The flow sensor 220 can monitor the changes in the flow of the coolant on the circulation pipeline 120. The flow information monitored by the flow sensor 220 can be transmitted to the control system, thereby facilitating the control system to make more accurate control.

[0062] The probe portion of the flow sensor 220 can be in direct contact with the coolant and connected to the control system via a signal line, thereby providing real-time feedback on coolant flow changes, maintaining flow fluctuations within a set range. This direct contact method can improve the accuracy of data acquisition. It should be noted that the sensors provided on the circulation pipeline 120 involved in the following embodiments, such as the pressure sensor 170 and the temperature sensor, can all be provided in a manner such that the probe portion is in direct contact with the coolant, and these sensors can all be connected to the control system by signal.

[0063] In some embodiments, please refer to Figure 1 The temperature control assembly 300 includes a heater 310, which is used to transfer heat to the cold plate 10. The heater 310 can heat up after being powered on.

[0064] The heater 310 is a heat source required by the cold plate 10 for heat exchange, and the temperature fluctuation can be generated by heat transfer between the cold plate 10 and the heater 310 .

[0065] In some embodiments, the temperature control component 300 also includes a temperature control electrical circuit 320, the heater 310 is arranged on the temperature control electrical circuit 320, and a first temperature sensor 330 for monitoring the temperature of the heater 310 and an on-off switch 340 for controlling the on and off of the temperature control electrical circuit 320 are also provided on the temperature control electrical circuit 320.

[0066] The first temperature sensor 330 can be connected to the control system to monitor the temperature of the heater 310 so that the control system can perform more precise control. It is understood that the power of the heater 310 can be adjusted according to the test requirements to ensure that the temperature of the coolant reaches the set value.

[0067] To ensure accuracy in monitoring the temperature of the heater 310 , the first temperature sensor 330 may be disposed near the heater 310 .

[0068] In some embodiments, please refer to Figure 1 The temperature control assembly 300 includes a second temperature sensor 350 disposed on the circulation pipeline 120 for monitoring the temperature of the coolant.

[0069] The second temperature sensor 350 can be disposed on the circulation pipeline 120 between the liquid return port 112 and the cold plate 10 . The second temperature sensor 350 can directly monitor the temperature of the coolant so that the control system can more accurately control the heating power of the heater 310 .

[0070] In some embodiments, the second temperature sensor 350 and the first temperature sensor 330 may be provided at the same time, thereby enabling the control system to achieve more accurate temperature control by comparing the temperature changes monitored by the two temperature sensors.

[0071] In some embodiments, please refer to Figure 1 A pressure sensor 170 is provided on the circulation pipeline 120, and the pressure sensor 170 is used to monitor the pressure of the coolant.

[0072] In some specific embodiments, the pressure sensor 170 includes a first pressure sensor 171 disposed between the liquid outlet 111 and the cold plate 10 , and a second pressure sensor 172 disposed between the cold plate 10 and the liquid return port 112 .

[0073] Here, by providing a pressure sensor 170 on each of the circulation pipe 120 flowing to the cold plate 10 and the circulation pipe 120 flowing out of the cold plate 10 , the pressure change of the coolant can be better monitored and controlled through analysis and comparison of the two pressure sensors 170 .

[0074] In some embodiments, please refer to Figure 2 The liquid monitoring component 400 includes a branch pipeline 410 connected to the circulation pipeline 120 and a detector 420 arranged on the branch pipeline 410. The branch pipeline 410 is used to transport the coolant in the circulation pipeline 120 to the detector 420. The detector 420 includes a detection unit for monitoring the parameter indicators of the coolant.

[0075] The liquid monitoring assembly 400 is a comprehensive monitoring structure that can monitor multiple parameters of the coolant. It is understood that after the liquid monitoring assembly 400 is installed, the coolant can flow from the circulation pipeline 120 to the branch pipeline 410 and enter the detector 420, and then the monitoring unit of the detector 420 completes the collection of parameter indicators.

[0076] In some embodiments, the detection unit may include at least one of a pH detection unit, a turbidity detection unit, a conductivity detection unit, and an ion detection unit.

[0077] pH value detection unit: uses glass electrode to measure and monitor the pH value of the coolant in real time, which is used to evaluate the chemical stability and corrosive risk of the coolant.

[0078] Turbidity detection unit: Utilizes the principle of infrared light scattering to quantify the suspended matter content in the coolant and evaluate the clarity and contamination level of the coolant.

[0079] Conductivity detection unit: uses a glass electrode for measurement, reflecting the total amount of dissolved solids in the coolant and indirectly evaluating the contamination level of the coolant.

[0080] Ion detection unit: used to detect the concentration of specific anions and cations in the coolant, such as copper ions, to assess the degree of contamination of the coolant.

[0081] Therefore, by collecting various parameter indicators, the physical and chemical properties of the coolant can be detected, ensuring real-time feedback on the corrosive changes of the coolant.

[0082] In some specific embodiments, please refer to Figure 3 The liquid monitoring component 400 also includes a detection box 430, and both ends of the branch pipeline 410 are exposed from the outside of the detection box 430 to form an inlet 411 and an outlet 412 respectively. The inlet 411 and the outlet 412 are connected to the circulation pipeline 120, and the detector 420 is accommodated in the detection box 430.

[0083] The detection box 430 can protect the detector 420 to prevent other signals from interfering with the accuracy of the detection results.

[0084] In some specific embodiments, multiple detectors 420 may be provided, each detector 420 corresponding to a detection unit. To this end, multiple branch pipelines 410 may be provided, one of which forms an inlet 411 and an outlet 412 so that the branch pipeline 410 is connected to the circulation pipeline 120. Other branch pipelines 410 may be connected in parallel to the branch pipeline 410, and then the required detector 420 may be provided on each branch pipeline 410.

[0085] Figure 3 This is a schematic structural diagram of the cabinet 600 provided in an embodiment of the present application.

[0086] In some embodiments, please refer to Figure 3 The corrosion cycle test device also includes a cabinet 600, which is the main frame of the corrosion cycle test device. The cabinet 600 can be made of corrosion-resistant materials to ensure the stability and durability of the device. The cabinet 600 is used to accommodate and set other components of the device, such as the aforementioned coolant circulation system 100, flow control component 200, temperature control component 300, liquid monitoring component 400 and control system.

[0087] In some embodiments, please refer to Figure 3 The top of the cabinet 600 is formed with a test platform 610 for users to perform relevant operations on the test platform. The test platform 610 includes a loading area 611, an observation area 612, a control display area 613 and an alarm area 614.

[0088] The loading area 611 is an area where the cold plate 10 is loaded, and the cold plate 10 can be connected and fixed to the loading area 611. As one embodiment, the cold plate 10 can be connected to the loading area 611 via a quick-connect connector 611a and restrained by a restraining structure provided on the loading area 611, thereby preventing the cold plate 10 from moving in the loading area 611.

[0089] In some specific embodiments, the restriction structure may be a snap-fit ​​structure, an elastic abutment structure, etc. The restriction structure may be restricted to the periphery of the cold plate 10 to prevent the cold plate 10 from moving.

[0090] The observation area 612 is an area for observing the test process in real time. The observation area 612 can be made of transparent acrylic, glass or other materials, so that light can pass through well to observe the internal conditions of the cabinet 600. The observation area 612 can be used to facilitate operators to observe the flow status of the coolant, etc.

[0091] The setting of the observation area 612 should be convenient for the operator to observe. The observation area 612 can be set at the front side of the test platform 610 and located at the right part of the test platform 610.

[0092] Please refer to Figure 3 The X direction is the length direction of the cabinet 600, the Y direction is the width direction of the cabinet 600, and the Z direction is the height direction of the cabinet 600. It can be understood that the test platform 610 is divided into the left and right parts in the X direction, and the front and rear parts in the Y direction, wherein the front part is closer to the operator. Based on this, the loading area 611 and the observation area 612 can both be set on the right part of the test platform 610. At the same time, the loading area 611 is set at the rear side and the observation area 612 is set at the front side. On the one hand, it makes the cold plate 10 further away from the operator, which can prevent the operator from being injured and ensure the safety of operation. On the other hand, it can make the observation area 612 closer to the operator, which is convenient for the operator to observe.

[0093] The control display area 613 includes a display screen 613a and a switch button 613b. The display screen 613a is installed on the left side of the test platform 610 and is located on the front side to facilitate the operator to perform related operations. The switch button 613b is set on one side of the display screen 613a.

[0094] The display screen 613a can use a high-resolution, high-contrast liquid crystal display to display the operating status, alarm information, parameter settings, detection data, etc. of the corrosion cycle test device. The corrosion cycle test device can also be controlled through the display screen 613a, and the operator can easily set the test parameters, start and stop the test, view monitoring data, etc.

[0095] The switch button 613b needs to be clearly marked to facilitate identification and operation by the operator. It is used to control basic operations such as the power switch, test start and stop of the corrosion cycle test device to ensure the safety and reliability of the test. The switch button 613b is connected to the control system to achieve precise control of the corrosion cycle test device through the program of the control system.

[0096] The alarm area 614 includes an alarm light 614a, which is located on the left and rear side of the test platform 610. The alarm light 614a is used to sound an alarm when an abnormal situation occurs during the test, reminding the operator to take timely measures. For example, when the temperature exceeds the set range, the coolant leaks, the coolant parameters change abnormally, etc., the alarm light 614a will flash and sound an alarm. The alarm light 614a is connected to the control system and is automatically triggered by the control system based on the monitored data.
