Description

Technical Field

[0001] This disclosure relates to the field of liquid cooling technology, and more specifically, to a water quality testing system and a water quality testing method. Background Technology

[0002] Liquid cooling technology is a heat dissipation technology that uses liquid as a cooling medium to absorb and dissipate heat. It leverages the high specific heat capacity and excellent thermal conductivity of liquids to rapidly conduct and remove heat generated during equipment operation, thus achieving efficient heat dissipation, such as in liquid-cooled servers in data centers.

[0003] Since the quality of the coolant directly affects the heat dissipation effect and operational stability of liquid cooling equipment, water quality testing is an indispensable and crucial step in the use of liquid cooling equipment. In related technologies, the water quality of coolant samples taken from the cooling structure of the liquid cooling equipment is typically judged based on preset water quality standards, which introduces a certain degree of judgment error. Summary of the Invention

[0004] This summary section is provided to briefly introduce the concepts, which will be described in detail in the subsequent detailed description section. This summary section is not intended to identify key or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] In a first aspect, this disclosure provides a water quality testing system, which includes a storage tank, a first valve, a circulating pump, a testing module, and a control module. The control module is connected to the first valve, the circulating pump, and the testing module. The first end of the first valve is connected to the outlet of the storage tank, and the second end of the first valve is connected to the inlet of the testing module. The circulating pump is located at the outlet of the storage tank. The storage tank is used to store coolant; The circulating pump is used to pump out the coolant from the storage tank; The control module is used to control the opening of the first valve and the start of the circulation pump, so that the outlet of the liquid storage tank is connected to the inlet of the detection module, and the coolant in the liquid storage tank is pumped into the detection module. The detection module is used to perform water quality detection on the coolant in the detection module to obtain first water quality detection data; The control module is also used to control the circulation pump to shut down, the first valve to shut down, the outlet of the liquid storage tank to connect to the inlet of the cooling structure of the liquid cooling equipment, the inlet of the detection module to connect to the outlet of the cooling structure, and to control the circulation pump to start, so as to pump the coolant in the cooling structure to the detection module. The detection module is also used to perform water quality testing on the coolant in the detection module to obtain second water quality test data; The control module is also used to compare the first water quality detection data and the second water quality detection data to obtain the water quality detection results of the coolant in the cooling structure.

[0006] Secondly, this disclosure provides a water quality testing method applied to the water quality testing system described in the first aspect above, the water quality testing method comprising: The outlet of the storage tank of the water quality testing system is connected to the inlet of the testing module of the water quality testing system so as to pump the coolant in the storage tank into the testing module; The coolant in the detection module is subjected to water quality testing to obtain the first water quality test data; The liquid outlet of the storage tank is connected to the liquid inlet of the cooling structure of the liquid cooling equipment, and the liquid inlet of the detection module is connected to the liquid outlet of the cooling structure, so as to pump the coolant in the cooling structure into the detection module. The coolant in the detection module is subjected to water quality testing to obtain second water quality test data; The first water quality test data and the second water quality test data are compared to obtain the water quality test results of the coolant in the cooling structure.

[0007] In the above technical solution, the coolant in the storage tank is first tested to obtain first water quality data. Then, the coolant in the cooling structure of the liquid cooling equipment is tested to obtain second water quality data. Finally, by comparing the first and second water quality data, the water quality test result of the coolant in the cooling structure is obtained. Using this system, the water quality of the coolant in the storage tank is used as a water quality benchmark, allowing for flexible judgment of the coolant quality in different liquid cooling equipment and reducing judgment errors. For example, when testing the water quality of liquid cooling equipment using different coolants, the coolant in the storage tank can be flexibly replaced according to the coolant used in the liquid cooling equipment, and this replacement can be used as a water quality benchmark to judge the water quality of the coolant in that liquid cooling equipment. This not only offers high flexibility but also reduces judgment errors.

[0020] Meanwhile, it is understood that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and related provisions.

[0021] The quality of the coolant in liquid cooling equipment directly affects the stability of the equipment's operations. Taking liquid-cooled servers as an example, before a liquid-cooled server is installed, it needs to undergo a series of processes, including assembly, sealing testing, draining and drying, and nitrogen purging. The quality control of the liquid-cooled server itself also affects the quality of the coolant. For example, liquid contamination in the cooling system may lead to increased bacteria, and copper contamination in the cooling system may result in higher copper content in the coolant. To ensure overall water quality, newly installed liquid-cooled servers require water quality testing to ensure their cleanliness and health, thereby guaranteeing their safe and stable operation.

[0022] In addition, after a period of use, the coolant within the cooling system of a liquid-cooled server may exhibit abnormal water quality, which can affect the server's stable operation. Therefore, it is necessary to conduct water quality testing on the liquid-cooled server before it is put into use to determine whether liquid flushing or coolant replacement is required.

[0023] In related technologies, combining on-site sampling in the computer room with laboratory testing is not only cumbersome but also inefficient. Each test item requires a certain amount of time, and water quality testing typically involves multiple tests, thus requiring a significant amount of time and making it impossible to quickly determine whether the coolant in the liquid-cooled server meets the required standards, thereby affecting the server's deployment and use. Furthermore, while the coolant sampled from the cooling structure of the liquid-cooled equipment is usually judged based on preset water quality standards, different batches of liquid-cooled servers may use different coolants, leading to a certain degree of judgment error.

[0024] In view of this, the present disclosure provides a water quality testing system and a water quality testing method to solve the above-mentioned technical problems.

[0025] The embodiments of this disclosure will be further explained below with reference to the accompanying drawings.

[0026] Figure 1 This is a structural block diagram of a water quality testing system according to an exemplary embodiment of the present disclosure, such as... Figure 1 As shown, the water quality testing system 10 includes a storage tank 11, a first valve 12, a circulation pump 13, a testing module 14, and a control module 15. The control module 15 is connected to the first valve 12, the circulation pump 13, and the testing module 14 respectively. The first end of the first valve 12 is connected to the outlet of the storage tank 11, and the second end of the first valve 12 is connected to the inlet of the testing module 14. The circulation pump 13 is located at the outlet of the storage tank 11.

[0027] The system includes a storage tank 11 for storing coolant; a circulation pump 13 for pumping coolant from the storage tank 11; a control module 15 for controlling the opening of the first valve 12 and the starting of the circulation pump 13, connecting the outlet of the storage tank 11 to the inlet of the detection module 14, and pumping the coolant from the storage tank 11 to the detection module 14; the detection module 14 for performing water quality testing on the coolant to obtain first water quality test data; the control module 15 also controls the closing of the circulation pump 13, the closing of the first valve 12, the connection of the outlet of the storage tank 11 to the inlet of the cooling structure of the liquid cooling equipment, the connection of the outlet of the cooling structure to the inlet of the detection module 14, and the starting of the circulation pump 13 to pump the coolant from the cooling structure to the detection module 14; the detection module 14 also performs water quality testing on the coolant to obtain second water quality test data; and the control module 15 compares the first and second water quality test data to obtain the water quality test result of the coolant in the cooling structure.

[0028] By employing the aforementioned water quality testing system, the water quality of the coolant in the storage tank is used as a benchmark, enabling flexible assessment of the coolant quality in different liquid cooling devices and reducing judgment errors. For example, when testing the water quality of liquid cooling devices using different coolants, the system can flexibly replace the coolant in the storage tank according to the coolant used by the device, and use this as a benchmark to assess the coolant quality in that device. This not only offers high flexibility but also reduces judgment errors.

[0029] In one possible configuration, the detection module includes a second valve, a first detection submodule, and a second detection submodule. The second valve, first detection submodule, and second detection submodule are each connected to a control module. The second valve is located at the inlet of the first detection submodule. The control module is also used to control the second valve to open, thereby pumping coolant from the storage tank to the first detection submodule. The first detection submodule performs water quality testing on the coolant within it, obtaining first water quality test data. The control module is also used to control the second valve to close, thereby pumping coolant from the cooling structure to the second detection submodule. The second detection submodule performs water quality testing on the coolant within it, obtaining second water quality test data.

[0030] For example, such as Figure 2As shown, the second valve 25 can be opened to pump the coolant in the storage tank 21 to the first detection submodule 241. The first detection submodule 241 performs water quality testing on the incoming coolant to obtain first water quality test data. Then, the second valve 25 is closed to pump the coolant in the cooling structure to the second detection submodule 242. This prevents the coolant in the cooling structure from flowing into the first detection submodule 241 and causing pipeline contamination, ensuring a clean testing environment for the first detection submodule 241. This improves the reliability of using the water quality test data from the first detection submodule 241 as a judgment standard, thereby increasing the accuracy of water quality testing.

[0031] It is worth noting that, in addition to being positioned between the first detection submodule 241 and the second detection submodule 242, the second valve 25 can also be positioned as follows: Figure 3 At position B, the second valve can have two outlets, connected to the first detection submodule 241 and the second detection submodule 242 respectively. This allows control over the flow of coolant into either the first detection submodule 241, the second detection submodule 242, or both simultaneously. It also prevents coolant from flowing into the first detection submodule 241 and causing pipe contamination, thus improving the accuracy of water quality detection. Specific configurations can be made according to requirements; this disclosure does not impose any limitations.

[0032] In a possible manner, the control module is further configured to pump the coolant in the reservoir to the second detection submodule before pumping the coolant in the cooling structure to the second detection submodule; the second detection submodule is further configured to perform water quality testing on the coolant in the second detection submodule to obtain third water quality test data; the control module is further configured to control the second valve to close when both the first water quality test data and the third water quality test data meet preset conditions, so as to pump the coolant in the cooling structure to the second detection submodule.

[0033] It should be noted that all sensors and instruments within the detection module have undergone rigorous calibration and optimization, possessing high sensitivity, high accuracy, and rapid response, enabling the acquisition of stable and reliable detection data in a short time. To further ensure the accuracy of water quality testing, automatic calibration and fault diagnosis functions can be performed before water quality testing, ensuring the continuity and accuracy of the testing process.

[0034] For example, such as Figure 2As shown, the first valve 23 and the second valve 25 can also be opened to pump the coolant in the storage tank 21 into the first detection submodule 241 and the second detection submodule 242 for automatic preprocessing. This means that the water quality test data of the first detection submodule 241 and the second detection submodule 242 can be calibrated and fault diagnosed based on preset standards. For example, if the difference between the test values ​​in the water quality test data of the first detection submodule 241 and the test values ​​of the preset standard is less than a preset range, it indicates that there are no contaminants affecting the test error in the first detection submodule 241 and the second detection submodule 242, and formal water quality testing can be performed to ensure the accuracy of the water quality test. The preset conditions can be set according to requirements, such as excessive differences between the two water quality test data or excessive differences from the preset standard, etc. This disclosure does not impose any restrictions on this.

[0035] In a possible manner, the control module is also used to control the coolant in the storage tank to be pumped into the detection submodule corresponding to the target detection data for cleaning when either the first water quality detection data or the third water quality detection data fails to meet the preset conditions, until the target detection data meets the preset conditions.

[0036] For example, if any target detection data in the first and third water quality detection data does not meet the preset conditions, it indicates that there may be water pollution within the water quality detection module affecting the accuracy of water quality detection. Therefore, the water quality detection submodule corresponding to the target detection data can be cleaned, or both water quality detection submodules can be cleaned simultaneously, until both the first and third water quality detection data meet the preset conditions. This ensures the accuracy of water quality detection.

[0037] In one possible configuration, the first end of the second valve is connected to the outlet of the first detection submodule, and the second end of the second valve is connected to the inlet of the second detection submodule. This allows the coolant in the storage tank to be pumped to both the first and second detection submodules simultaneously when the second valve is open, and to be pumped to the second detection submodule while preventing the coolant in the cooling structure from being pumped to the first detection submodule when the second valve is closed.

[0038] For example, the second valve 25 can be positioned between the first detection submodule 241 and the second detection submodule 242, thus allowing the water quality detection system to have only one vent. It can also be positioned as follows: Figure 3At position B, the second valve can have two outlets, connecting to the first detection submodule 241 and the second detection submodule 242 respectively. In this case, two vents are required, and the coolant can be controlled to flow only into the first detection submodule 241, only into the second detection submodule 242, or simultaneously into both detection submodules. This also prevents coolant from flowing into the first detection submodule 241 from the cooling structure, thus avoiding pipe contamination and improving the accuracy of water quality detection. Specific configurations can be made according to requirements; this disclosure does not impose any limitations.

[0039] It should be noted that the coolant in the storage tank can be used to clean the abnormal detection submodule, or the abnormal detection submodule can be cleaned with pure water through an external cleaning module. The specific settings can be configured according to requirements, and this disclosure does not impose any restrictions on this.

[0040] To facilitate the illustration of the detection process in conjunction with the internal structure of the detection module, the following illustration of the detection process is based on the internal structure of the second detection submodule. The detection process of the first detection submodule can be referred to the detection process of the second detection submodule, and will not be repeated here.

[0041] In one possible configuration, the detection module includes a sampling unit and an analysis unit, which are respectively connected to the control module. The sampling port of the sampling unit is connected to the liquid inlet of the detection module. The sampling unit is used to sample the coolant flowing into the liquid inlet of the detection module through the sampling port at a preset frequency and then input the sample into the analysis unit. The analysis unit is used to perform water quality testing on the coolant sampled in the analysis unit.

[0042] For example, such as Figure 2 The water quality testing system 20 shown, taking the second testing submodule 242 as an example, may include a sampling unit 2421, a flow control valve 2422, an analysis unit 2423, and a waste liquid collection unit 2424. The sampling unit 2421, flow control valve 2422, and analysis unit 2423 are respectively connected to the control module 29. The sampling port of the sampling unit 2421 is connected to the inlet of the second testing submodule 242. The sampling unit 2421 can sample the coolant flowing into the second testing submodule 242 through the sampling port at a preset frequency, and then input the sample to the analysis unit 2423 through the flow control valve 2422. This allows for uniform sampling of the coolant, improving the accuracy of the test results.

[0043] In one possible configuration, the detection module further includes a flow control valve connected to the control module. The first end of the flow control valve is connected to the outlet of the sampling unit, and the second end of the flow control valve is connected to the inlet of the analysis unit. The flow control valve is used to control the flow rate of the coolant input from the sampling unit to the analysis unit and to feed back the flow data to the control module. The control module is also used to adjust the pumping frequency of the circulating pump in response to the flow data fed back by the flow control valve.

[0044] For example, the flow control valve 2422 is used to control the flow rate of the coolant input from the sampling unit 2421 to the analysis unit 2423, and to feed back the flow data to the control module 29, so as to achieve precise control of the sampling process.

[0045] It should be noted that the control module can control the pumping frequency of the circulating pump based on the flow data fed back by the flow control valve. For example, if the coolant flow rate corresponding to the flow data fed back by the flow control valve already meets the coolant quantity required by the analysis unit for water quality testing, the pumping frequency of the circulating pump can be reduced or the circulating pump can be turned off. The specific settings can be made according to the requirements, and this disclosure does not impose any restrictions on this.

[0046] In this embodiment, the water quality testing system can be configured with a high-precision flow control valve and a micro-circulation pump to control the flow rate of the coolant passing through the sampling unit. It can also accurately extract a certain amount of coolant sample according to a preset sampling procedure to ensure the uniformity and representativeness of the sampling. Furthermore, the sampling unit has an automatic cleaning function, which flushes the sampling pipeline after each sampling to prevent sample residue and cross-contamination, ensuring the accuracy of the next sampling.

[0047] In one possible configuration, the analysis unit includes multiple analysis sub-units, each corresponding to a water quality test item, and the multiple analysis sub-units are connected to the control module respectively. The analysis sub-unit is used to perform water quality testing on the coolant sampled within the analysis sub-unit in response to the coolant sampled within the analysis sub-unit reaching a preset detection amount.

[0048] For example, such as Figure 2 The water quality testing system 20 shown includes multiple analysis sub-units in each testing sub-module. When the control module 29 detects that the sampled coolant in any analysis sub-unit has reached the preset detection amount, it can start the water quality testing process of the corresponding analysis sub-unit. The multiple analysis sub-units do not interfere with each other and can simultaneously detect multiple water quality indicators in parallel.

[0049] In other words, an analytical unit can integrate multiple water quality detection sensors and analytical instruments to simultaneously detect multiple water quality indicators, such as pH, turbidity, total copper, sulfate, chloride ions, total hardness, total alkalinity, total bacterial count, and other key water quality indicators. This disclosure does not impose any limitations on this.

[0050] Examples include pH detection, ion concentration detection, total hardness detection, and COD value detection based on electrochemical detection principles; turbidity detection based on optical detection principles; colorimetric detection for total iron and total copper; conductivity detection based on physical detection principles; and total bacterial count detection based on microbial detection principles, etc. This disclosure does not limit these applications.

[0051] This approach not only avoids errors and omissions that may result from step-by-step testing, providing comprehensive data support for accurate water quality assessment of liquid cooling equipment and effectively ensuring its operational safety and stability, but also significantly shortens the testing cycle and greatly improves the deployment speed of liquid cooling equipment, meeting the need for rapid deployment.

[0052] In addition, the coolant flowing out of the analysis unit can flow into, for example, Figure 2 The waste liquid collection unit 2424 shown in the figure then flows into the waste liquid tank 28 to avoid causing environmental pollution.

[0053] In one possible configuration, the outlet of the liquid storage tank is connected to the first female connector of the inlet of the cooling structure via a first male connector, and the inlet of the detection module is connected to the second female connector of the outlet of the cooling structure via a second male connector.

[0054] For example, matching male and female connectors can be used to quickly and reliably connect to the coolant inlet and outlet of the liquid cooling equipment, ensuring no leakage during sampling and not affecting the normal operation of the liquid cooling equipment.

[0055] In one possible manner, the control module is used to generate a water quality test result indicating that the coolant water quality in the cooling structure is normal when the difference between the test value in the second water quality test data and the test value in the first water quality test data is less than or equal to a preset threshold; or, when the difference between the test value in the second water quality test data and the test value in the first water quality test data is greater than a preset threshold, generate a water quality test result indicating that the coolant water quality in the cooling structure is abnormal.

[0056] For example, it can be done through, as Figure 2 The control module shown processes the first and second water quality test data. If the difference between the test value in the second water quality test data and the test value in the first water quality test data is less than or equal to a preset threshold, it indicates that the water quality difference between the coolant in the cooling structure of the liquid cooling equipment and the coolant in the storage tank is not significant. Therefore, it can be determined that the water quality of the coolant in the cooling structure is normal. Otherwise, it is determined that the water quality of the coolant in the cooling structure is abnormal.

[0057] In this embodiment, the control module connects to each analysis subunit, receiving and processing water quality detection data uploaded by the analysis subunits in real time. The control module amplifies, filters, and performs analog-to-digital conversion on the data signals, converting analog signals into digital signals, and records and stores the values ​​of various water quality parameters in real time. Through the built-in high-performance microprocessor and intelligent algorithms, the module performs comprehensive analysis, calculation, and comparison of various water quality parameters. Based on preset algorithms and calibration curves, it converts signal values ​​into corresponding water quality parameter concentration values ​​and performs data correction and compensation operations to improve the accuracy and reliability of the data.

[0058] It should be noted that the control module can determine whether the coolant quality in the cooling structure is normal by comparing the water quality test data uploaded by the two detection submodules. It is also compatible with determining whether the coolant quality is normal by comparing the preset standard water quality parameters. This disclosure does not impose any restrictions on this.

[0059] In addition, the control module also has data storage capabilities, capable of recording long-term historical testing data to provide data support and trend analysis for the long-term operation and maintenance of the liquid cooling equipment. Simultaneously, the control module can automatically control the sampling frequency, preprocessing procedures, and testing parameters based on the test results, achieving automation and intelligence throughout the entire testing process.

[0060] In other words, the control module enables automated control of the entire testing process, including automatic sampling, automatic preprocessing, automatic detection, automatic data processing and analysis, as well as intelligent operations such as automatically adjusting the sampling frequency and detection parameters based on the test results. This reduces the impact of human factors on water quality testing and improves the stability and accuracy of the test.

[0061] In one possible manner, the water quality testing system also includes a communication module connected to the control module. The communication module is used to send at least one of the following to the terminal: the operating status of each module of the water quality testing system, the water quality testing results, and the prompt information. The prompt information is generated when the water quality testing results indicate an abnormality in the water quality of the coolant in the cooling structure.

[0062] For example, the water quality testing system also includes a communication module, which can use wireless communication technology to transmit test results, equipment operating status and prompt information to the equipment management platform or the terminal equipment of maintenance personnel in real time, so that maintenance personnel can remotely test the water quality of the liquid cooling equipment anytime and anywhere.

[0063] For example, when water quality parameters are detected to exceed preset safety thresholds, the communication module can issue an audible and visual alarm signal and push detailed prompts, including abnormal parameters, equipment number, and detection time, to the terminal device of maintenance personnel so that they can take appropriate measures in a timely manner, such as replacing the coolant, cleaning the liquid cooling structure of the liquid cooling equipment, or conducting further inspection and maintenance of the liquid cooling equipment.

[0064] In one possible configuration, the water quality testing system further includes a purge port, a gas cylinder, and a vent port, with the purge port and vent port respectively connected to a control module. The gas cylinder stores gas used to fill the pipeline within the water quality testing system. The purge port is used to introduce gas from the gas cylinder into the pipeline of the water quality testing system. The vent port is used to expel gas from the pipeline of the water quality testing system. The control module is also configured to, in response to stopping water quality testing, disconnect the outlet of the storage tank from the inlet of the cooling structure and disconnect the outlet of the cooling structure from the inlet of the testing module. It also controls the connection between the outlet of the storage tank and the inlet of the testing module, and opens the purge port and vent port to allow gas from the gas cylinder to be introduced into the pipeline of the water quality testing system through the purge port until the liquid content at the vent port is lower than a preset level, at which point it closes the purge port and vent port. The control module is also configured to control the vent port to open, and after venting the gas from the pipeline of the water quality testing system, control the vent port to close and pump the coolant from the storage tank into the testing module.

[0065] It is worth noting that the water quality testing system can be purged with nitrogen when not in use to prevent external pollutants from contaminating the internal pipes of the system, thereby further ensuring the accuracy of the water quality testing.

[0066] Therefore, the water quality testing system can perform water quality testing on the same batch of liquid cooling equipment as follows: Figure 4 As shown. Combined with Figure 2The system structure allows for the following steps: Before testing the first liquid-cooled device, coolant can be added to the storage tank 21, followed by opening the first valve 23 and the second valve 25, while keeping the purge port 26 and the vent port 27 closed. The vent port is then opened to purge nitrogen from the water quality testing system. After the nitrogen is completely purged, the vent port 27 is closed. The circulation pump 22 is then started, and the water quality data from the first and second detection submodules 241 and 242 are confirmed to be within a preset range. The circulation pump 22, first valve 23, and second valve 25 are then closed. The outlet of the storage tank 21 is connected to the first female connector of the cooling structure's inlet of the first liquid-cooled device via a first male connector, and the inlet of the detection module 24 is connected to the second female connector of the cooling structure's outlet of the first liquid-cooled device via a second male connector. Then, the circulating pump 22 performs multiple water quality index tests through multi-channel sampling, compares the water quality test data of the first detection submodule 241 and the second detection submodule 242, and obtains the corresponding water quality test results. If there is an abnormality, a prompt message is sent to remind the operation and maintenance personnel to check. If the water quality is normal, the water quality test process of the first liquid cooling equipment ends.

[0067] Next, water quality testing is performed on the second liquid cooling device. Similarly, the liquid level in the storage tank is checked first. If it is sufficient, no addition is required, and no nitrogen purging step is needed. The other processes are the same as the testing process for the first liquid cooling device, and will not be repeated here.

[0068] Finally, after the entire batch of liquid cooling equipment has been tested, disconnect the quick connector between the water quality testing system and the liquid cooling equipment. Open the first and second valves, as well as the purge port and vent. Charge nitrogen through the purge port using a nitrogen cylinder for the preset time. After this time, check if the vent still contains liquid. If it does, continue charging with nitrogen. If it does not contain liquid, stop charging and close the purge port and vent to prevent external contaminants from polluting the internal piping of the water quality testing system, further ensuring the accuracy of the water quality testing. This concludes the water quality testing for this batch of liquid cooling equipment.

[0071] This disclosure provides a water quality testing system integrating sampling, detection, data processing, control, and communication functions. It can be easily connected to the cooling structure piping of liquid-cooled equipment, enabling rapid online testing of the coolant within the cooling structures of liquid-cooled servers, liquid-cooled dummy loads, and liquid-cooled cabinets. This eliminates the need for complex disassembly and relocation of the liquid-cooled equipment, unlike on-site rapid testing in computer rooms and step-by-step laboratory testing methods, thus improving testing efficiency and convenience. Furthermore, when testing the water quality of liquid-cooled equipment using different coolants, the system can flexibly replace the coolant in the storage tank according to the coolant used by the equipment, using this replacement as a water quality benchmark for judging the coolant quality within the equipment. This not only offers high flexibility but also reduces judgment errors.

[0072] Figure 5 This is a flowchart illustrating a water quality testing method according to an exemplary embodiment of the present disclosure, which can be applied to the aforementioned water quality testing system. (Refer to...) Figure 5 The water quality testing method may include the following steps: S501: Connect the outlet of the storage tank of the water quality testing system to the inlet of the testing module of the water quality testing system to pump the coolant in the storage tank into the testing module.

[0073] It should be noted that the coolant in the storage tank is from the same batch as the coolant used in the liquid cooling equipment to be tested, and the coolant in the storage tank is clean and uncontaminated, thus it can be used as a standard for judging water quality.

[0074] For example, such as Figure 2 The water quality testing system 20 shown controls the opening of the first valve 23 to connect the outlet of the storage tank 21 with the inlet of the testing module 24, thereby controlling the opening of the circulation pump 22 to pump the coolant in the storage tank 21 into the testing module 24. That is, the coolant in the storage tank flows into the testing module 24 after passing through the circulation pump 22 and the first valve 23.

[0075] S502: Perform water quality testing on the coolant in the detection module to obtain the first water quality test data.

[0076] For example, such as Figure 2 The water quality detection system 20 shown uses the detection module 24 to detect the water quality of the coolant in the detection module and obtain the first water quality detection data.

[0077] S503: Connects the outlet of the control tank to the inlet of the cooling structure of the liquid cooling equipment and the inlet of the detection module to the outlet of the cooling structure, so as to pump the coolant in the cooling structure to the detection module.

[0078] For example, liquid cooling equipment includes at least one of liquid-cooled servers, liquid-cooled cabinets, and liquid-cooled dummy loads, which are not limited in this disclosure.

[0079] For example, such as Figure 2 The water quality testing system 20 shown controls the circulation pump 22 and the first valve 23 to close, controls the outlet of the liquid storage tank 21 to connect with the inlet of the cooling structure of the liquid cooling device A, and connects the inlet of the testing module 24 to the outlet of the cooling structure, thereby controlling the circulation pump 22 to start, forming a loop from the liquid storage tank 21, the circulation pump 22, the cooling structure to the testing module 24, so as to pump the coolant in the cooling structure to the testing module 24.

[0080] S504: Perform water quality testing on the coolant in the detection module to obtain second water quality test data.

[0081] For example, such as Figure 2 The water quality testing system 20 shown uses the testing module 24 to test the water quality of the coolant in the testing module and obtain the second water quality test data.

[0082] S505: Compare the first water quality test data and the second water quality test data to obtain the water quality test results of the coolant in the cooling structure.

[0083] For example, such as Figure 2 The water quality monitoring system 20 shown can process the first and second water quality monitoring data through the control module 29 to obtain the water quality monitoring results of the coolant in the cooling structure. The control module 29 is communicatively connected to the various modules and components within the water quality monitoring system 20.

[0084] By employing the above method, the water quality of the coolant in the storage tank is used as a water quality benchmark, enabling flexible judgment of the coolant water quality in different liquid cooling devices and reducing judgment errors. For example, when conducting water quality testing on liquid cooling devices using different coolants, the coolant in the storage tank can be flexibly replaced according to the coolant used by the liquid cooling device, and this replacement can be used as a water quality benchmark to judge the water quality of the coolant in that liquid cooling device. This not only offers high flexibility but also reduces judgment errors.

[0085] It should be noted that the same detection module can be used to first test the coolant in the storage tank to obtain the first water quality test data, which is then uploaded to the control module for storage. Next, the coolant in the cooling structure is tested to obtain the second water quality test data, which is also uploaded to the control module. The control module processes the two sets of uploaded water quality test data to obtain the final water quality test result. The detection module can be flushed between the two testing processes to ensure the accuracy of the water quality tests.

[0086] Alternatively, adopt such as Figure 2 The two detection modules shown are used to detect the coolant in the reservoir to obtain first water quality data, and to detect the coolant in the cooling structure to obtain second water quality data. This avoids contamination of the pipes of the detection module used to detect the coolant in the reservoir by the coolant in the cooling structure, thus improving the accuracy of water quality detection. Specific configurations can be made according to requirements, and this disclosure does not impose any limitations on this.

[0087] The following describes an example of the water quality testing process with reference to the accompanying drawings.

[0088] In one possible approach, water quality testing is performed on the coolant within the detection module to obtain second water quality test data. This includes: pumping coolant from the reservoir to a first detection submodule within the detection module; and performing water quality testing on the coolant within the first detection module to obtain first water quality test data. Alternatively, water quality testing is performed on the coolant within the detection module to obtain second water quality test data. This includes: pumping coolant from the cooling structure to a second detection submodule within the detection module; and performing water quality testing on the coolant within the second detection submodule to obtain second water quality test data.

[0089] For example, such as Figure 2 The water quality testing system 20 shown includes a testing module 24 comprising a first testing submodule 241 for testing the water quality of the coolant in the storage tank and a second testing submodule 242 for testing the water quality of the coolant in the cooling structure. A second valve 25 controls whether the coolant flowing into the inlet of the testing module 24 is pumped to the first testing submodule 241.

[0090] For example, such as Figure 2As shown, the second valve 25 can be opened to pump the coolant in the storage tank 21 to the first detection submodule 241. The first detection submodule 241 performs water quality testing on the incoming coolant to obtain first water quality test data. Then, the second valve 25 is closed to pump the coolant in the cooling structure to the second detection submodule 242. This prevents the coolant in the cooling structure from flowing into the first detection submodule 241 and causing pipeline contamination, ensuring a clean testing environment for the first detection submodule 241. This improves the reliability of using the water quality test data from the first detection submodule 241 as a judgment standard, thereby increasing the accuracy of water quality testing.

[0091] In one possible manner, the water quality testing method further includes: pumping the coolant in the storage tank to the second detection submodule before pumping the coolant in the cooling structure to the second detection submodule within the testing module; performing water quality testing on the coolant in the second detection submodule to obtain third water quality test data. Pumping the coolant in the cooling structure to the second detection submodule within the testing module includes: pumping the coolant in the cooling structure to the second detection submodule within the testing module when both the first and third water quality test data meet preset conditions.

[0092] For example, such as Figure 2 As shown, the first valve 23 and the second valve 25 can also be opened to pump the coolant in the storage tank 21 into the first detection submodule 241 and the second detection submodule 242 for automatic preprocessing. That is, the water quality test data from the first detection submodule 241 and the second detection submodule 242 can be preprocessed based on preset conditions. For example, if the difference between the test values ​​in the water quality test data of the first detection submodule 241 and the test values ​​of the preset standard is less than a preset range, it indicates that there are no contaminants affecting the detection error in the first detection submodule 241 and the second detection submodule 242, and formal water quality testing can be carried out to ensure the accuracy of the water quality test. The preset conditions can be set according to needs, such as if the difference between the two water quality test data is too large, or if the difference from the preset standard is too large, etc. This disclosure does not impose any restrictions on this.

[0093] In one possible manner, the water quality testing method further includes: when either the first water quality testing data or the third water quality testing data fails to meet the preset conditions, controlling the coolant in the storage tank to be pumped into the testing submodule corresponding to the target testing data for cleaning, until the target testing data meets the preset conditions.

[0094] For example, if any target detection data in the first and third water quality detection data does not meet the preset conditions, it indicates that there may be water pollution within the water quality detection module, affecting the accuracy of water quality detection. Therefore, the water quality detection submodule corresponding to the target detection data can be cleaned, or both water quality detection submodules can be cleaned simultaneously, until both the first and third water quality detection data meet the preset conditions. This ensures the accuracy of water quality detection.

[0095] In one possible manner, water quality testing of the coolant within the detection module includes: sampling the coolant within the detection module at a preset frequency and inputting the sampled coolant into an analysis unit within the detection module; and performing water quality testing on the sampled coolant within the analysis unit. The control method further includes: adjusting the pumping frequency of the coolant pumped into the detection module in response to the flow rate data of the sampled coolant within the detection module.

[0096] For example, such as Figure 2 The water quality testing system 20 shown includes a second testing submodule 242, which may include a sampling unit 2421, a flow control valve 2422, an analysis unit 2423, and a waste liquid collection unit 2424. The sampling unit 2421, flow control valve 2422, and analysis unit 2423 are connected to the control module 29. The sampling port of the sampling unit 2421 is connected to the inlet of the second testing submodule 242. The sampling unit 2421 can sample the coolant flowing into the second testing submodule 242 through the sampling port at a preset frequency, and then input the sample to the analysis unit 2423 through the flow control valve 2422. The flow control valve 2422 controls the flow rate of the coolant input from the sampling unit 2421 to the analysis unit 2423 and feeds back the flow data to the control module 29. This allows for uniform sampling of the coolant, improving the accuracy of the test results.

[0097] It should be noted that the control module can control the pumping frequency of the circulating pump based on the flow data fed back by the flow control valve. For example, if the coolant flow rate corresponding to the flow data fed back by the flow control valve already meets the coolant quantity required by the analysis unit for water quality testing, the pumping frequency of the circulating pump can be reduced or the circulating pump can be turned off. The specific settings can be made according to the requirements, and this disclosure does not impose any restrictions on this.

[0098] In one possible manner, the analysis unit includes multiple analysis sub-units, each analysis sub-unit corresponding to a water quality test item, and performs water quality testing on the coolant sampled within the analysis unit, including: in response to the coolant sampled in any target analysis sub-unit among the multiple analysis sub-units reaching a preset detection amount, performing water quality testing on the coolant sampled in the target analysis sub-unit.

[0099] For example, such as Figure 2The water quality testing system 20 shown includes multiple analysis sub-units in each testing sub-module. When the control module 29 detects that the sampled coolant in any analysis sub-unit has reached the preset detection amount, it can start the water quality testing process of the corresponding analysis sub-unit. The multiple analysis sub-units do not interfere with each other and can simultaneously detect multiple water quality indicators in parallel.

[0100] This approach not only avoids errors and omissions that may result from step-by-step testing, providing comprehensive data support for accurate water quality assessment of liquid cooling equipment and effectively ensuring its operational safety and stability, but also significantly shortens the testing cycle and greatly improves the deployment speed of liquid cooling equipment, meeting the need for rapid deployment.

[0101] In one possible manner, the first water quality test data and the second water quality test data are compared to obtain the water quality test result of the coolant in the cooling structure, including: if the difference between the test value in the second water quality test data and the test value in the first water quality test data is less than or equal to a preset threshold, a water quality test result indicating that the coolant in the cooling structure is normal is generated; or, if the difference between the test value in the second water quality test data and the test value in the first water quality test data is greater than a preset threshold, a water quality test result indicating that the coolant in the cooling structure is abnormal is generated.

[0102] For example, it can be done through, as Figure 2 The control module shown processes the first and second water quality test data. If the difference between the test value in the second water quality test data and the test value in the first water quality test data is less than or equal to a preset threshold, it indicates that the water quality difference between the coolant in the cooling structure of the liquid cooling equipment and the coolant in the storage tank is not significant. Therefore, it can be determined that the water quality of the coolant in the cooling structure is normal. Otherwise, it is determined that the water quality of the coolant in the cooling structure is abnormal.

[0103] In some possible ways, the water quality testing method also includes sending at least one of the following to the terminal: the operating status of each module in the water quality testing system, the water quality testing results, and the prompt information, wherein the prompt information is generated when the water quality testing results indicate an abnormality in the water quality of the coolant in the cooling structure.

[0104] For example, the water quality testing system also includes a communication module, which can use wireless communication technology to transmit test results, equipment operating status and prompt information to the equipment management platform or the terminal equipment of maintenance personnel in real time, so that maintenance personnel can remotely test the water quality of the liquid cooling equipment anytime and anywhere, so that maintenance personnel can carry out further inspection and maintenance of the liquid cooling equipment in a timely manner.

[0105] In some possible embodiments, the water quality testing method further includes: in response to stopping water quality testing, controlling the disconnection of the liquid outlet of the storage tank from the liquid inlet of the cooling structure and the disconnection of the liquid outlet of the cooling structure from the liquid inlet of the testing module, and controlling the connection between the liquid outlet of the storage tank and the liquid inlet of the testing module, and opening the purge port and vent port of the water quality testing module; charging the gas in the gas cylinder of the water quality testing system into the pipeline of the water quality testing system through the purge port until the liquid content at the vent port of the water quality testing system is lower than a preset content; controlling the purging port and vent port to close. Pumping the coolant in the storage tank into the testing module includes: controlling the vent port to open, venting the gas in the pipeline of the water quality testing system, controlling the vent port to close, and pumping the coolant in the storage tank into the testing module.

[0106] It is worth noting that the water quality testing system can be purged with nitrogen when not in use to prevent external pollutants from contaminating the internal pipes of the system, thereby further ensuring the accuracy of water quality testing. Correspondingly, the water quality testing system needs to undergo nitrogen removal before testing begins; details can be found in the corresponding water quality testing system embodiments, which will not be elaborated upon here.
