[0002] Currently, in the field of liquid cooling technology, especially for heat dissipation systems of liquid-cooled servers, cleanliness testing is crucial to ensuring the stable operation of liquid cooling systems and maintaining server heat dissipation efficiency. Liquid cooling systems circulate coolant between the radiator and heat-generating elements, transferring heat from the heat-generating elements to the radiator, and then dissipating the heat into the environment, achieving efficient heat dissipation. During the production, assembly, transportation, and use of liquid cooling systems, the coolant or its circulation pipelines may be contaminated with particulate matter, microorganisms, chemical impurities, etc. These contaminants may not only clog the pipelines, affecting the flow efficiency of the coolant, but may also cause wear or corrosion to the precision components inside the server, leading to performance degradation or even malfunction.

[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0029] To address the issues of poor detection accuracy and increased workload for personnel in liquid cooling system media cleanliness testing in related technologies, this application provides a media cleanliness testing system.
[0030] like Figures 1 to 3As shown, the media cleanliness detection system includes a first water quality detection device 10, a first pipeline 20, a second water quality detection device 40, and a second pipeline 50. The first water quality detection device 10 includes a buffer tank 11 and a detection component disposed within the buffer tank 11. The buffer tank 11 has a receiving cavity, an inlet 111, and a first outlet 112. The inlet 111 is connected to the first outlet 112 through the receiving cavity. The detection component is used to detect at least one of the following: particle concentration, pH value, and conductivity in the media entering the receiving cavity. The drain port of the device under test 30 is connected to the inlet 111 through the first pipeline 20. The second water quality detection device 40 is disposed on the first pipeline 20 to detect at least one of the following: particle concentration, pH value, and conductivity in the media discharged from the drain port. The inlet of the device under test 30 is connected to the first outlet 112 through the second pipeline 50.
[0031] By applying the technical solution of this embodiment, the water quality detection device can detect in real time at least one of the particle concentration, pH value, and conductivity of the medium (coolant) flowing through the device under test 30. This covers important parameters for evaluating water cleanliness and chemical stability. Through the above monitoring, the system can comprehensively assess the cleanliness of the coolant, ensuring that the coolant will not cause physical or chemical damage to the precision components inside the device under test 30. This solves the problem in related technologies where the detection accuracy of the cleanliness of the liquid cooling system medium is poor and the workload of the staff is increased. It not only improves the detection efficiency and accuracy but also reduces the workload of the staff. At the same time, by detecting the water quality on the first pipeline 20 and in the containment cavity of the buffer tank 11, dual water quality detection of the coolant is achieved from the time it flows out of the device under test 30 until it is recirculated back into the system. This ensures comprehensive monitoring of the coolant. Even if one detection point fails, the other can serve as a backup, increasing the stability and reliability of the system.
[0032] Specifically, the second water quality testing device 40 tests the coolant as soon as it leaves the testing device 30, capturing the most direct information on water quality changes, such as whether impurities are generated due to corrosion or wear inside the equipment. The first water quality testing device 10 can test the coolant quality after preliminary treatment by the buffer tank 11, evaluate the working effect of the buffer tank, and ensure that the coolant reaches the specified cleanliness standard before recirculation.
[0033] like Figure 2As shown, the detection components include a first turbidity sensor 14, a first pH sensor 15, and a first conductivity sensor 16. The first turbidity sensor 14 detects the particle concentration in the medium, the first pH sensor 15 detects the pH value of the medium, and the first conductivity sensor 16 detects the conductivity of the medium. Thus, the first turbidity sensor 14, the first pH sensor 15, and the first conductivity sensor 16 monitor the particle concentration, pH value, and conductivity of the cooling medium, respectively. These three parameters cover the core indicators for evaluating the cleanliness and chemical state of the cooling medium. By monitoring these parameters in real time, the system can comprehensively understand the water quality status of the cooling medium, ensuring the efficient and safe operation of the cooling system.
[0034] In this embodiment, the first turbidity sensor 14 can accurately measure the concentration of suspended particles in the medium. When the particle concentration exceeds the normal range, it can quickly locate possible sources of contamination, such as wear, corrosion, or external pollution, helping to take timely measures to remove impurities and avoid impacting the system. The first pH sensor 15 monitors the pH of the medium, and the first conductivity sensor 16 monitors the conductivity of the medium. These sensors can provide early warnings of chemical precipitation, dissolution, or medium deterioration, ensuring that the medium does not corrode or react with internal materials of the equipment, maintaining the long-term stability of the equipment and extending its service life.
[0035] like Figure 3 As shown, the second water quality detection device 40 includes a liquid-passing pipe 44, a second turbidity sensor 41, a second pH sensor 42, and a second conductivity sensor 43. The liquid-passing pipe 44 has a first detection end, a second detection end, and a third detection end communicating with its inner cavity; the inner cavity of the liquid-passing pipe 44 is connected to the first pipeline 20. The second turbidity sensor 41 is used to detect the particle concentration in the medium, the second pH sensor 42 is used to detect the pH value in the medium, and the second conductivity sensor 43 is used to detect the conductivity in the medium. Specifically, the second turbidity sensor 41 is located at the first detection end, the second pH sensor 42 is located at the second detection end, and the second conductivity sensor 43 is located at the third detection end. Thus, the first, second, and third detection ends of the liquid flow pipe 44 are respectively equipped with a second turbidity sensor 41, a second pH sensor 42, and a second conductivity sensor 43, enabling real-time multi-parameter water quality detection along the coolant circulation path. This ensures that the most direct water quality information can be obtained immediately after the coolant leaves the detection device 30, improving the timeliness and accuracy of the detection. Simultaneously, the aforementioned arrangement of the liquid flow pipe 44 prevents the coolant from directly contacting the sensor during detection; instead, the coolant contacts the sensor's detection end through the inner cavity of the liquid flow pipe 44. This protects the sensor from direct damage by any solid particles or corrosive substances present in the medium, extending the sensor's lifespan and reducing maintenance frequency.
[0036] In this embodiment, since the first water quality detection device 10 and the second water quality detection device 40 monitor the water quality parameters of the coolant at different locations, this provides a basis for data comparison. By analyzing the data differences between the two detection points, the preliminary treatment effect of the buffer tank 11 on the coolant can be evaluated, which helps to optimize the design of the buffer tank and improve the water treatment efficiency.
[0037] Optionally, the media cleanliness detection system also includes a control module and an alarm module. The control module is electrically connected to the first turbidity sensor 14, the first pH sensor 15, the first conductivity sensor 16, the second turbidity sensor 41, the second pH sensor 42, and the second conductivity sensor 43. The alarm module is electrically connected to the control module. Specifically, when the detection value of the first turbidity sensor 14 is greater than or equal to a first preset value, a first alarm signal is issued through the alarm module; and / or, when the detection value of the first pH sensor 15 is greater than or equal to a second preset value, a second alarm signal is issued through the alarm module; and / or, when the detection value of the first conductivity sensor 16 is greater than or equal to a third preset value, a third alarm signal is issued through the alarm module; and / or, when the detection value of the second turbidity sensor 41 is greater than or equal to a fourth preset value, a fourth alarm signal is issued through the alarm module; and / or, when the detection value of the second pH sensor 42 is greater than or equal to a fifth preset value, a fifth alarm signal is issued through the alarm module; and / or, when the detection value of the second conductivity sensor 43 is greater than or equal to a sixth preset value, a sixth alarm signal is issued through the alarm module. In this way, the three sensors of the first water quality detection device 10 and the second water quality detection device 40 can promptly report abnormal changes in the state of the medium. When any parameter deviates from the set normal range, the system will immediately issue an alarm to prompt maintenance personnel to perform cleaning, medium replacement or other maintenance operations, thus avoiding equipment performance degradation or failure due to medium contamination and improving maintenance efficiency and equipment reliability.
[0038] Optionally, the media cleanliness detection system further includes a circulation pump 60, which is installed on the first pipeline 20 and / or the second pipeline 50; and / or, the media cleanliness detection system further includes a filter 80, which is installed on the first pipeline 20 and / or the second pipeline 50, and is located close to the buffer tank 11. In this way, the circulation pump 60 can increase the circulation speed and power of the cooling medium in the system, ensuring that the medium can flow quickly and evenly through the device under test 30 and the buffer tank 11. This not only accelerates the water quality detection process but also promotes the uniform distribution of impurities in the medium, making the water quality detection results more objective and accurate. Simultaneously, the filter 80, positioned close to the buffer tank 11, can perform real-time filtration of the medium during the cooling medium circulation process, removing suspended particles and impurities, improving the cleanliness of the medium, and reducing equipment wear and malfunctions.
[0039] like Figure 1 As shown, the media cleanliness detection system also includes a circulation pump 60 and a filter 80. The circulation pump 60 is installed on the second pipeline 50, and the filter 80 is installed on the first pipeline 20 and the second pipeline 50, close to the buffer tank 11. Thus, the circulation pump 60 provides circulation power for the coolant, causing it to circulate within the pipeline. The filter 80 on the second pipeline 50 filters the coolant before it flows out of the buffer tank 11, removing impurities and particulate matter, protecting the subsequent circulation pump 60 and pipeline from contamination. The filter 80 on the first pipeline 20 performs a second filtration before the coolant flows back to the buffer tank 11, removing any impurities and particulate matter that may be generated inside the server, protecting the buffer tank 11 and the circulation pump 60 from contamination.
[0040] like Figure 1 and Figure 2 As shown, the buffer tank 11 also has a return port 113 communicating with the receiving cavity. The second pipeline 50 includes a main pipe section 51, a first branch pipe section 52, and a second branch pipe section 53. The first end of the main pipe section 51 is connected to the inlet of the device under test 30. The first end of the first branch pipe section 52 is connected to the second end of the main pipe section 51, and the second end of the first branch pipe section 52 is connected to the first outlet section 112. The first end of the second branch pipe section 53 is connected to the second end of the main pipe section 51, and the second end of the second branch pipe section 53 is connected to the return port 113. Thus, through the combination of the main pipe section 51, the first branch pipe section 52, and the second branch pipe section 53, the system can more flexibly distribute and circulate the cooling medium. The main pipe section 51 is directly connected to the inlet of the device under test 30, ensuring a stable input of the medium; the first branch pipe section 52 and the second branch pipe section 53 are respectively connected to the first outlet section 112 and the return port 113 of the buffer tank 11, forming an efficient circulation loop, improving the uniformity and coverage of the medium circulation.
[0041] Optionally, the media cleanliness detection system further includes a first control valve 90, which is disposed on the first pipeline 20 to control at least one of the on / off state, flow rate, and flow velocity of the first pipeline 20; and / or, the media cleanliness detection system further includes a second control valve 100, which is disposed on the second pipeline 50 to control at least one of the on / off state, flow rate, and flow velocity of the second pipeline 50; and / or, the media cleanliness detection system further includes a pressure detection device 110, which is disposed on the first pipeline 20 and / or the second pipeline 50 to detect hydraulic pressure; and / or, the media cleanliness detection system further includes a one-way valve 70, which is disposed on the second pipeline 50, and the conduction direction of the one-way valve 70 is from the buffer tank 11 to the device under test 30. Thus, the configuration of the first control valve 90 and the second control valve 100 allows the system to intelligently adjust the on / off state, flow rate, and velocity of the first pipeline 20 and the second pipeline 50, ensuring that the circulation of the cooling medium is both efficient and energy-saving. Simultaneously, the pressure detection device 110 enables the system to continuously monitor the pressure level in the cooling circulation, which is crucial for preventing pipeline leaks, pressure overload, or cavitation. Through real-time pressure data, the system can respond promptly and adjust the operating status of the circulating pump to avoid damage to the cooling system and the device under test 30, ensuring the safe and stable operation of the equipment. The aforementioned configuration of the check valve 70 ensures that the cooling medium can only flow from the buffer tank 11 to the device under test 30, preventing backflow. This plays an important role in maintaining the quality of the medium and reducing cross-contamination within the system.
[0042] like Figure 1 As shown, the media cleanliness detection system also includes a first control valve 90, a second control valve 100, a pressure detection device 110, and a one-way valve 70. The pressure detection device 110 is installed on the first pipeline 20 and the second pipeline 50. The pressure detection device 110 on the second pipeline 50 measures the pressure of the coolant before it enters the server product, ensuring the pressure is within a safe range to prevent product damage or performance degradation due to excessively high or low pressure. The pressure detection device 110 on the first pipeline 20 measures the pressure of the coolant flowing out of the server, ensuring the pressure is within a safe range to prevent equipment malfunction due to abnormal pressure.
[0043] like Figure 2As shown, the buffer tank 11 also has an exhaust port 114, and the first water quality detection device 10 further includes a liquid level detection device 12, an exhaust pipe, and an exhaust valve 13. The liquid level detection device 12 is electrically connected to the control module to detect the liquid level in the buffer tank 11; when the liquid level exceeds a preset range, a seventh alarm signal is issued via the alarm module. The exhaust pipe is connected to the exhaust port 114, and the exhaust valve 13 is installed on the exhaust pipe to control its on / off state. Thus, the liquid level detection device 12, electrically connected to the control module, can monitor the liquid level in the buffer tank 11 in real time and trigger the alarm module to issue a seventh alarm signal when the level exceeds a preset range. This improves the safety and reliability of the system, preventing overflow due to excessively high liquid levels or pump dry running due to excessively low liquid levels, reducing potential dangers and equipment damage. Simultaneously, the connection between the exhaust pipe and the exhaust port 114, and the installation of the exhaust valve 13, effectively remove air from the system and balance the pressure. During the operation of the cooling system, the accumulation of air can affect the efficiency and stability of the medium circulation. By automatically or manually controlling the opening and closing of the exhaust valve, air can be removed in time, maintaining the stability of the internal pressure of the system and optimizing the cooling performance.
[0044] like Figure 2 As shown, the liquid level detection device 12 includes a high float level switch 121 and a low float level switch 122. The high float level switch 121 and the low float level switch 122 use floats to issue a high liquid level alarm signal when the liquid level in the buffer tank 11 rises to the set high liquid level, reminding the operator to stop adding water or take other measures to prevent coolant overflow; when the liquid level in the buffer tank 11 drops to the set low liquid level, an low liquid level alarm signal is issued to remind the operator to add coolant in time to avoid malfunctions such as the circulation pump running dry due to low liquid level.
[0045] In this embodiment, combined with the alarm function of the liquid level detection device 12, the system can provide immediate warning of abnormal liquid levels, prompting maintenance personnel to respond quickly and take measures such as filling the liquid or checking for leaks to prevent more serious problems from occurring. This supports the implementation of preventive maintenance strategies and reduces unplanned downtime of the equipment.
[0046] Optionally, the buffer tank 11 also has a second outlet section 115 spaced apart from the first outlet section 112, and the first water quality detection device 10 further includes an outlet pipe and a third control valve. The outlet pipe is connected to the second outlet section 115. The third control valve is located on the outlet pipe to control at least one of the following: the on / off state of the outlet pipe, the flow rate, and the flow velocity. This arrangement of the second outlet section 115 provides additional circulation path options for the cooling medium, enhancing the system's flexibility in the medium circulation path. When the first outlet section 112 is being maintained or inspected, the system can switch to the second outlet section 115 to ensure continuous cooling circulation and reduce downtime. Simultaneously, the third control valve, located on the outlet pipe, allows for precise control of the flow rate and velocity of the cooling medium through the second outlet section 115.
[0047] like Figure 1 As shown, the media cleanliness detection system also includes a flow sensor 120, which is installed on the second pipeline 50 to measure the flow rate of coolant in the pipeline and convert the flow information into an electrical signal to be transmitted to the control system for real-time monitoring and adjustment of the flow rate.
[0048] like Figure 1 As shown, the media cleanliness detection system also includes a proportional valve 130, which controls the flow rate of coolant entering the device under test by adjusting the flow rate in the second branch pipe section 53, so as to meet the cooling requirements under different operating conditions.
[0049] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0050] The water quality testing device can detect at least one of the following in real time: particle concentration, pH value, and conductivity of the medium (coolant) flowing through the device under test. This covers important parameters for evaluating water cleanliness and chemical stability. Through the above monitoring, the system can comprehensively assess the cleanliness of the coolant, ensuring that the coolant will not cause physical or chemical damage to the precision components inside the device under test. This solves the problem of poor detection accuracy and increased labor intensity for personnel in related technologies for detecting the cleanliness of liquid cooling system media. It not only improves detection efficiency and accuracy but also reduces the labor intensity of personnel. At the same time, by detecting the water quality separately on the first pipeline and in the buffer tank's containment cavity, dual water quality detection is achieved from the time the coolant flows out of the device under test until it is recirculated back into the system. This ensures comprehensive monitoring of the coolant. Even if one detection point fails, the other can serve as a backup, increasing the system's stability and reliability.
