Description

Technical Field

[0001] This invention relates to the field of liquid-cooled server cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] The cold plate is the core heat dissipation component of a cold plate liquid-cooled server. After aging tests in the liquid-cooled production environment, contaminants such as wastewater, chemicals, and even microorganisms may easily accumulate inside the cold plate. These contaminants not only affect the server's heat dissipation efficiency but may also threaten its stable operation. If these contaminants are not cleaned in time after aging tests, they will remain inside the cold plate piping and may cause corrosion during transportation, easily harming the customer's liquid-cooled environment. Therefore, cleaning and maintenance of cold plate liquid-cooled servers after aging tests is crucial. However, existing cleaning methods are not comprehensive enough in terms of cleanliness assessment. Using relatively simple detection methods, such as visual inspection or single-sensor detection, cannot fully reflect the cleanliness of the cold plate after cleaning, thus affecting the long-term stable operation of the server.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] As mentioned in the background section, existing cleaning processes for server liquid cooling plates typically involve rinsing the internal channels with cleaning fluid, followed by manual visual inspection or detection of the cleanliness level using a single sensor. This cleanliness assessment is not comprehensive enough to fully reflect the cleanliness of the cooling plate after cleaning. Furthermore, existing equipment lacks intelligent data analysis and processing capabilities, requiring extensive manual data processing and analysis, which is not only inefficient but also prone to errors. Therefore, to address the aforementioned technical problems, the cleaning equipment provided in this application incorporates a first detection module 150 within the second pipe fitting 140. This first detection module 150 can detect the quality information of the cleaning fluid within the second pipe fitting 140. Based on this quality information, the cleanliness level of the target workpiece is fed back. Specifically, the quality information includes at least pH value, conductivity, and turbidity. This allows for multi-dimensional feedback on the cleanliness level without the need for manual identification, achieving intelligent cleaning.

[0027] Please refer to Figure 1 and Figure 2 This application provides a cleaning device, comprising: a cabinet 100, wherein a first liquid storage component 110 and a second liquid storage component are disposed within the cabinet 100; a first pipe 130, the two ends of the first pipe 130 being connected to the first liquid storage component 110 and the liquid inlet of a target workpiece, respectively, to input cleaning fluid into the target workpiece; a second pipe 140, the two ends of the second pipe 140 being connected to the liquid outlet of the target workpiece and the second liquid storage component, wherein the cleaning fluid in the target workpiece flows back to the second liquid storage component through the second pipe 140; and a first detection module 150, at least a portion of the first detection module 150 being disposed within the second pipe 140, to detect the quality information of the cleaning fluid within the second pipe 140, the quality information including at least: pH value, conductivity, and turbidity.

[0028] The cleaning equipment provided in this application includes a cabinet 100, a first pipe fitting 130, a second pipe fitting 140, and a first detection module 150. The cabinet 100 houses a first liquid storage component 110 and a second liquid storage component. The two ends of the first pipe fitting 130 are respectively connected to the first liquid storage component 110 and the inlet of the target workpiece to introduce cleaning fluid into the target workpiece. The two ends of the second pipe fitting 140 are respectively connected to the outlet of the target workpiece and the second liquid storage component, allowing the cleaning fluid in the target workpiece to flow back to the second liquid storage component through the second pipe fitting 140. At least a portion of the first detection module 150 is disposed within the second pipe fitting 140 to detect the quality information of the cleaning fluid within the second pipe fitting 140, including at least pH value, conductivity, and turbidity. The cleaning fluid is transported from the first liquid storage component 110 to the target workpiece through the first pipe fitting 130 for cleaning, and then flows back to the second liquid storage component through the second pipe fitting 140 for collection and reuse. This recycling model significantly reduces cleaning fluid consumption and lowers operating costs. The equipment can adjust parameters such as the flow rate, pressure, and temperature of the cleaning fluid based on real-time data from the first detection module 150, achieving intelligent cleaning. This automated control reduces manual intervention, improves cleaning efficiency and accuracy, and facilitates intelligent detection and feedback of cleanliness levels.

[0029] Specifically, the cleaning equipment also includes: a second detection module 160, which is disposed in the first liquid storage component 110, and detects the quality information of the cleaning liquid in the first liquid storage component 110; and a display component 101, which is disposed on the cabinet 100, wherein the first detection module 150 and the second detection module 160 are respectively connected to the display component 101 to display the quality information of the cleaning liquid on the display component 101.

[0030] The second detection module 160 is installed within the first liquid storage component 110. It can monitor the quality of the cleaning fluid in the storage tank in real time, including information such as pH value, conductivity, and turbidity. Combined with the quality information of the return cleaning fluid detected by the first detection module 150, it forms a complete cleaning fluid quality monitoring system. This dual detection mechanism ensures that the cleaning fluid entering the target workpiece always maintains a high level of cleanliness, thereby improving cleaning effect and efficiency. The display component 101 allows users to view the quality information of the cleaning fluid in real time, including the status of the cleaning fluid in the storage tank and the return pipeline. This visual operation greatly enhances the user's operational convenience and experience. Users can intuitively understand the key parameters in the cleaning process, adjust the cleaning strategy in a timely manner, or handle abnormal situations, improving the accuracy and efficiency of the operation. The addition of the second detection module 160 enables the equipment to continuously monitor the cleaning fluid in the storage tank. Once the cleaning fluid quality is detected to drop below a preset threshold, the equipment may issue a warning signal through the display component 101, prompting the user to replace or replenish the cleaning fluid. This prevents equipment failure or poor cleaning effect due to poor cleaning fluid quality, ensuring the normal operation of the equipment and the successful completion of the cleaning task. The display component 101 can not only display the quality information of the cleaning fluid in real time, but also record the data of each cleaning process. Through data analysis, it can evaluate the trend of liquid quality change and cleaning effect at different cleaning stages, and provide data support for optimizing the cleaning process and improving cleaning quality and efficiency.

[0031] In specific implementation, the first detection module 150 and / or the second detection module 160 include: a pH value detection sensor, wherein a pH value detection sensor is respectively installed in the first liquid storage component 110 and / or the second pipe fitting 140 to detect the pH value of the cleaning liquid in the first liquid storage component 110 and / or the second pipe fitting 140; and a conductivity sensor, wherein a conductivity sensor is respectively installed in the first liquid storage component 110 and / or the second pipe fitting 140 to detect the conductivity of the cleaning liquid in the first liquid storage component 110 and / or the second pipe fitting 140.

[0032] Real-time monitoring using pH and conductivity sensors allows for precise understanding of the cleaning fluid's chemical properties, including acidity, alkalinity, and conductivity. Based on this information, the equipment can promptly adjust the cleaning fluid formula or replace it with a new one, ensuring optimal cleaning performance and improving cleaning efficiency and effectiveness. pH and conductivity are key parameters reflecting a liquid's corrosiveness and conductivity. In the liquid-cooled server industry, excessively low pH or high conductivity in the cleaning fluid can cause metal corrosion or conductive deposits, damaging the workpiece. Real-time monitoring and control of these parameters effectively prevents such problems and protects the workpiece from damage. Abnormal pH and conductivity in the cleaning fluid can also cause corrosion or buildup on the equipment itself, affecting its long-term operational performance. Real-time monitoring of these parameters helps maintain the equipment's health and extend its lifespan.

[0033] In this application, the cleaning equipment further includes: a filter element 210, at least partially disposed within the first pipe fitting 130, through which the cleaning fluid in the first liquid storage component 110 flows into the target workpiece after being filtered; a differential pressure detection element 211, connected to both the inlet and outlet ends of the filter element 210, for detecting the pressure difference between the inlet and outlet ends of the filter element 210; and a heating element 220, disposed within the first liquid storage component 110, for heating the cleaning fluid within the first liquid storage component 110. The filter element 210, disposed within the first pipe fitting 130, ensures that the cleaning fluid is purified before entering the target workpiece, removing any possible solid particles and impurities, thereby preventing secondary contamination or damage to the workpiece during the cleaning process. This is crucial for improving cleaning quality and protecting the workpiece. The differential pressure detection element 211 detects the pressure difference across the filter element 210, enabling real-time monitoring of filter blockage. When the differential pressure exceeds a preset threshold, the equipment can issue an alarm, prompting the need to clean or replace the filter components. This ensures the safety and efficiency of the cleaning process and prevents reduced flow rate or excessive system pressure due to filter clogging. A heating element 220 is located within the first liquid storage unit 110 to heat the cleaning solution. In some applications, increasing the temperature of the cleaning solution enhances its dissolving and cleaning capabilities, especially for grease, wax, or other temperature-sensitive contaminants. The heating function helps to remove stubborn stains more thoroughly, improving cleaning efficiency and cleanliness. Through real-time monitoring by the differential pressure detection unit 211, the equipment can intelligently determine the health status of the filter component 210, avoiding scheduled maintenance and allowing maintenance based on actual needs, thus reducing maintenance costs and equipment downtime. The inclusion of the filter and heating elements also reduces the need for pre-treatment of the cleaning solution, further saving costs. The efficient use of the heating element 220 and the filter component 210 reduces reliance on chemical cleaning agents, lowering environmental pollution. Simultaneously, through intelligent control of the cleaning solution's temperature and flow rate, the equipment achieves efficient cleaning while also realizing energy conservation and environmental protection goals.

[0034] Furthermore, the cleaning equipment also includes: a liquid level detection component 230, disposed within the first liquid storage component 110, for detecting the liquid level of the cleaning liquid within the first liquid storage component 110; the liquid level detection component 230 is signal-connected to the heating component 220, so that when the liquid level detection component 230 detects that the liquid level of the cleaning liquid has dropped to a set threshold, it controls the heating component 220 to stop operating; and a first temperature detection component 241, at least partially disposed within the first liquid storage component 110, for detecting the temperature of the cleaning liquid within the first liquid storage component 110. Specifically, the liquid level detection component 230 includes a high float level 202, an analog level gauge 203, and a low float level 204. The high float level 202 is used to detect the highest liquid level of the cleaning fluid, and the low float level 204 is used to detect the lowest liquid level of the cleaning fluid. The liquid level detection component 230 (including the high float level 202, analog level gauge 203, and low float level 204) can monitor the liquid level of the cleaning fluid in the first liquid storage component 110 in real time. When the liquid level drops to a preset safety threshold, the liquid level detection component sends a signal to the heating component 220 to control it to stop operating, preventing the heating component from working in a liquid-free state and avoiding equipment damage and safety hazards. The first temperature detection component 241 can monitor the temperature of the cleaning fluid in real time, ensuring that the cleaning fluid reaches and maintains the ideal cleaning temperature after heating. The data collected by the liquid level and temperature detection components can be fed back to the intelligent control system of the equipment to realize automatic adjustment and early warning. For example, the equipment can automatically stop heating when the liquid level is too low, and automatically adjust the heating power when the temperature deviates from the set value. This not only improves the intelligence level of the equipment, but also simplifies the operation process and reduces the difficulty of operation and potential error rate.

[0035] The cleaning equipment also includes: a first flow detection component 251, at least partially disposed within the first pipe fitting 130, to detect the flow rate of the cleaning fluid within the first pipe fitting 130; a first pressure detection component 261, at least partially disposed within the first pipe fitting 130, to detect the pressure of the cleaning fluid within the first pipe fitting 130; and a second temperature detection component 242, at least partially disposed within the first pipe fitting 130, to detect the temperature within the first pipe fitting 130. The first flow detection component 251 can monitor the flow rate of the cleaning fluid in real time, ensuring a stable flow rate during the cleaning process and achieving the designed cleaning efficiency. The first pressure detection component 261 can detect the pressure of the cleaning fluid, helping the equipment maintain a constant pressure and preventing damage to the target workpiece due to excessive pressure or poor cleaning effect due to insufficient pressure. The second temperature detection component 242 monitors the temperature of the cleaning fluid. Temperature control is crucial for effectively removing certain types of dirt, ensuring that the cleaning fluid operates at the optimal temperature to improve the cleaning effect. These detection components, integrated with the equipment's control system, provide real-time feedback on flow rate, pressure, and temperature during the cleaning process. This allows the control system to intelligently adjust the input parameters of the cleaning fluid based on real-time data, achieving more precise cleaning control and improving cleaning quality and efficiency. By continuously monitoring flow rate, pressure, and temperature, the cleaning equipment can promptly detect anomalies. For example, a sudden drop in flow rate may indicate pipeline blockage, abnormal pressure may be related to equipment malfunction or the condition of the target workpiece, and temperature fluctuations may affect the chemical properties of the cleaning fluid. This real-time monitoring helps prevent equipment failures and ensures the safety of the cleaning process.

[0036] In this application, the cleaning equipment further includes: a first power unit 281, disposed on and connected to the first pipe fitting 130, for providing driving force to the cleaning fluid within the first pipe fitting 130; and a first one-way valve 291, disposed on and connected to the first pipe fitting 130, located at the outlet end of the first power unit 281. The addition of the first power unit 281 (typically a water pump or compressor) ensures that the cleaning fluid can be delivered to the inlet of the target workpiece through the first pipe fitting 130 with sufficient pressure and flow, improving the cleaning effect. Especially when the target workpiece has a complex internal structure, or the pipeline is long and tortuous, the driving force of the power unit is crucial to ensuring effective flow of the cleaning fluid and coverage of all cleaning areas. The first check valve 291 is located at the outlet end of the first power unit 281. It effectively prevents the cleaning fluid from flowing back from the first pipe 130 to the first storage unit 110 during or after cleaning, thus avoiding recontamination of the cleaning fluid before achieving the desired cleaning effect and ensuring the purity and efficiency of the cleaning fluid. The check valve protects the system from pressure shocks or equipment damage caused by backflow of the cleaning fluid. Especially after the power unit stops working, the check valve prevents backflow of the cleaning fluid due to gravity or pressure difference, ensuring the overall safety and reliability of the equipment. The power unit automatically controls the flow of the cleaning fluid, reducing the need for manual operation, simplifying the equipment's operation, and making the cleaning process more automated and convenient. Simultaneously, the automatic action of the check valve eliminates the need for operators to pay extra attention to the fluid flow direction, reducing operational complexity and potential human error.

[0037] Furthermore, the cleaning equipment also includes: a second pressure detection component 262, at least partially disposed within the first pipe fitting 130, located at the end of the first pipe fitting 130 near the target workpiece; and a third pressure detection component 263, at least partially disposed within the second pipe fitting 140, located at the end of the second pipe fitting 140 near the target workpiece. The second pressure detection component 262, located at the end of the first pipe fitting 130 near the target workpiece, monitors the pressure when the cleaning fluid is introduced into the target workpiece. The third pressure detection component 263, located at the end of the second pipe fitting 140 near the target workpiece, monitors the pressure when the cleaning fluid flows back from the workpiece. This arrangement ensures that the pressure of the cleaning fluid is accurately measured both when it enters and exits the workpiece during the cleaning process, facilitating real-time monitoring of pressure changes. By continuously monitoring the pressure entering and exiting the target workpiece, the cleaning equipment can promptly detect abnormal pressure conditions, such as sudden increases or decreases in pressure, which may indicate pipe blockage or leakage. The equipment can issue an early warning via the display component 101, prompting operators to promptly check and handle the situation, avoiding poor cleaning results or equipment damage due to abnormal pressure. The data collected by the second pressure detection unit 262 and the third pressure detection unit 263 can be used to analyze pressure loss during the cleaning process, thereby optimizing cleaning parameters, such as adjusting the flow rate, pressure, or temperature of the cleaning fluid, to achieve the best cleaning effect. Furthermore, by adjusting the pressure, excessive pressure damage to the target workpiece can be avoided, protecting the integrity and function of the workpiece. The detected pressure data can be combined with information from the first detection module 150 and the second detection module 160, and comprehensively analyzed by the equipment's intelligent control system to automatically adjust the cleaning process, achieving intelligent control of the cleaning process and improving cleaning efficiency and accuracy.

[0038] In the embodiments provided in this application, the cabinet 100 is provided with multiple water supply interfaces 102 and multiple water return interfaces 103, with each water supply interface 102 and each water return interface 103 corresponding to one another. The first pipe fitting 130 includes: multiple first branch lines 131, one end of each first branch line 131 being connected to the outlet of the first liquid storage component 110, and the other end of each first branch line 131 being connected to each water supply interface 102 corresponding to one another; and a main water outlet pipe 132, with both ends of the main water outlet pipe 132... The first pipe fitting 140 is connected to the target workpiece and one of the multiple water supply interfaces 102. The second pipe fitting 140 includes multiple second branches 141, one end of which is connected to the inlet of the second liquid storage component, and the other end of which is connected to a corresponding return water interface 103. Each second branch 141 is equipped with a first detection module 150. A return water main pipe 142 is also provided, with both ends connected to the target workpiece and one of the return water interfaces 103. The design of multiple water supply interfaces 102 and return water interfaces 103 allows the equipment to connect and clean multiple target workpieces simultaneously, significantly improving cleaning efficiency. This design is ideal for large-scale production or maintenance operations, greatly shortening cleaning time and increasing capacity and efficiency. Each target workpiece is connected to the liquid storage component via an independent first branch 131 and second branch 141, meaning that the cleaning process for each workpiece is independent, avoiding cross-contamination that may occur due to liquid circulation between workpieces and ensuring the cleanliness of each workpiece. The multi-branch design allows the equipment to flexibly adjust its cleaning strategy according to the cleaning needs of different workpieces. For example, it can control the flow rate, pressure, or type of cleaning fluid in different branches, thus enabling targeted cleaning of workpieces with different materials or structures, improving the equipment's adaptability and versatility. A first detection module 150 is installed on each second branch 141 to monitor the quality information of the cleaning fluid returning to each workpiece in real time, including pH value, conductivity, and turbidity, ensuring the quality of the liquid during the cleaning process and improving the reliability of the cleaning effect. The configuration of the outlet main pipe 132 and return main pipe 142 allows for more efficient distribution and recycling of cleaning fluid resources, reducing unnecessary waste, optimizing resource utilization, and lowering operating costs. The independent branch and main pipe design makes operation and maintenance more intuitive and simple. Users can easily identify and control the cleaning process of each workpiece. Furthermore, equipment maintenance and troubleshooting are easier, allowing for individual inspection or maintenance of a branch without stopping the machine.

[0039] The cleaning equipment also includes: an identification module, located within cabinet 100, used to identify the model of the target workpiece and control the cleaning parameters of the cleaning fluid in the first pipe 130 based on the model of the target workpiece. These cleaning parameters include at least the flow rate, pressure, and temperature of the cleaning fluid. A data storage module, located on cabinet 100, is signal-connected to both the first detection module 150 and the identification module. The identification module can automatically identify the model of the target workpiece and automatically adjust the cleaning parameters such as the flow rate, pressure, and temperature of the cleaning fluid according to different workpiece models, achieving a customized cleaning process. This intelligent identification function avoids the complexity and potential errors of manually setting parameters, improving cleaning efficiency and accuracy. The data storage module, signal-connected to both the first detection module 150 and the identification module, can record and store key data from each cleaning process, including the model of the target workpiece, the cleaning parameters used, and the quality information of the cleaning fluid. Through long-term accumulation and analysis of this data, cleaning strategies can be continuously optimized, improving equipment maintenance and cleaning effectiveness. The stored data provides a traceability basis for the cleaning process, facilitating quality control and problem troubleshooting. When cleaning results are unsatisfactory or equipment malfunctions, the cause of the problem can be located by reviewing stored data, allowing for timely adjustments or repairs to ensure cleaning quality and equipment operational stability. The identification module automatically identifies the target workpiece and adjusts cleaning parameters, reducing the need for manual operation and lowering the risk of operational errors. Simultaneously, the data storage module records equipment operating status, facilitating monitoring and early warning, and improving the safety of the cleaning process. The data storage module also records the equipment's usage history and performance data, providing a basis for equipment maintenance and management. Data analysis can predict equipment maintenance needs, reduce unexpected failures, and lower maintenance costs.

[0040] Specifically, incorporating Radio Frequency Identification (RFID) or Near Field Communication (NFC) technology into the identification module enables contactless automatic identification of target workpiece models without manual intervention, improving identification speed and accuracy. For workpieces without built-in RFID tags, a high-precision QR code or barcode scanner can be added to the identification module to obtain the workpiece model by scanning the markings on the workpiece, thus achieving automated identification as well. A database containing various workpiece models and their cleaning parameters can be built. After identifying a target workpiece, the identification module can quickly search and load the corresponding cleaning parameters from the database, enabling personalized cleaning settings.

[0041] This application establishes a cloud-based intelligent dispatch center integrating functional modules such as equipment management, task allocation, and data analysis. A highly available and scalable cloud service infrastructure is employed to ensure stable platform operation and data security. IoT modules (such as embedded computers and wireless communication modules) are integrated into the cleaning equipment, enabling it to connect to the cloud platform via Wi-Fi, 4G / 5G, LoRaWAN, or other wireless communication technologies. The equipment needs to be able to upload real-time status information, including but not limited to equipment operating status, liquid level, temperature, pressure, and water quality information. The equipment automatically collects the above status information during operation and uploads it to the cloud periodically or when triggered by specific events. Uploaded information should be transmitted encrypted to ensure data security and privacy. The cloud platform uses algorithmic models to analyze equipment status and workpiece cleaning needs, automatically planning and allocating cleaning tasks. The algorithmic model needs to consider factors such as the current load of the equipment, workpiece priority, cleaning time window, and equipment maintenance plan to optimize the cleaning process and improve equipment utilization efficiency. The platform monitors equipment status in real time. Upon detecting any anomalies (such as equipment malfunction, low liquid level, excessively high temperature, or abnormal pressure), it immediately sends alarms to equipment maintenance personnel or remote operators, while simultaneously displaying fault information on the equipment for rapid response and handling. The equipment should possess automated control functions, such as automatic start-up, automatic stop-up, and automatic adjustment of cleaning parameters. The cloud platform can send control commands to the equipment when tasks are assigned or equipment status changes, enabling remote control and automated operation.

[0042] The cleaning equipment disclosed in this application is specifically used for pure water cleaning and cleanliness testing of cold-plate liquid-cooled servers after aging tests. This equipment, through pure water cleaning and advanced testing technology, ensures that the cold-plate liquid-cooled server 400 achieves a high degree of cleanliness after aging tests, thereby guaranteeing the stability and reliability of the server's subsequent operation. The purpose of this application is to provide a pure water cleaning and cleanliness testing device for cold-plate liquid-cooled servers after aging tests. This device utilizes pure water as the cleaning fluid combined with advanced testing technology to achieve a comprehensive assessment of the cleanliness of the cold plates after cleaning. This application incorporates a built-in pure water supply system to ensure the supply of high-quality pure water for dissolving and rinsing to remove dirt and impurities. The testing module includes pH, turbidity, and conductivity sensors to monitor the acidity / alkalinity, residual microparticles, and cleanliness level within the cold plate piping after cleaning. The equipment incorporates an intelligent data processing system that automatically collects, processes, and analyzes the testing data, quantifies the cleaning effect, and generates a detailed testing report, achieving a comprehensive and accurate assessment of the cleanliness of the cold plates after cleaning. The equipment boasts advantages such as environmental safety, efficient cleaning, accurate assessment, improved maintenance efficiency, and reduced maintenance costs, providing a more reliable and efficient solution for production environment testing of cold plate liquid-cooled servers.

[0043] like Figure 3The diagram illustrates the implementation process of this invention in the production and testing of a cold-plate liquid-cooled server. The production and testing process mainly includes material input, server assembly, pressure holding test, constant pressure liquid injection, aging test, cleanliness test, draining, drying, nitrogen filling, and packaging. This method adds cold plate pipeline cleaning and cleanliness testing equipment after the aging test and before draining, drying, and nitrogen filling. This ensures the cleanliness of the cold plate pipeline after the aging test and avoids problems such as cold plate corrosion during server transportation, which could affect the customer's liquid cooling environment.

[0044] The cleanliness testing equipment cabinet 100 is made of stainless steel with rust prevention treatment and surface painting according to its specific functional requirements. The cabinet has sufficient structural rigidity and strength to ensure that the overall frame, internal supports, and related structural components of the equipment do not experience significant shaking, vibration, or deformation during normal operation. A keyboard 105, a touch screen (display component 101), and an alarm light 104 are located in suitable positions within the cabinet to enable setting equipment operating parameters, displaying operating status, and providing alarm information. The equipment has nine sets of cleaning interfaces, including a water supply interface 102 and a water return interface 103. Each set of interfaces is independent and can be used independently for cleaning, testing, and parameter setting. Barcodes and indicator lights are located nearby for interface identification and binding. The main water return pipe 142 and the main water outlet pipe 132 are used to connect the equipment cleaning interfaces to quick-connect components. The equipment water outlet quick connector 420 connects to the server water inlet, and the equipment water return quick connector 410 connects to the server water outlet. The pure water stored in the equipment flows from the equipment outlet through the outlet pipe and outlet quick connector into the server cold plate. After passing through the complex pipeline inside the server cold plate, it flows out through the return quick connector and return pipe, and finally flows back into the equipment from the equipment return port, completing the entire cleaning cycle of the server cold plate pipeline.

[0045] like Figure 2The diagram shown is a schematic of the piping principle of the cleanliness testing equipment for cold-plate liquid-cooled servers according to this application. It includes a water storage tank (first liquid storage component 110), a high-float level gauge 202, an analog level gauge 203, a low-float level gauge 204, a heating component 220, a fifth control valve 315 (manual drain valve), a second power component 282 (automatic drain pump), a second one-way valve 292 (drain one-way valve), a fourth control valve 314 (automatic drain valve), a filter component 210 (filter), a differential pressure detection component 211 (differential pressure sensor), a first power component 281 (water supply pump), a first one-way valve 291 (water supply one-way valve), a first flow detection component 251 (water supply flow sensor), a first pressure detection component 261 (water supply pressure sensor), and a second temperature detection component 242 (water supply temperature sensor). The system includes: second control valve 312 and third control valve 313 (pressure relief valves), eighth control valve 318 (water supply three-way valve), second flow detection component 252 (branch flow sensor), second pressure detection component 262 (server front-end pressure sensor), third pressure detection component 263 (server back-end pressure sensor), first detection module 150, first control valve 311 (branch electric proportional valve), fourth pressure detection component 264 (return water pressure sensor), first liquid storage component 110 (circulating water tank), second detection module 160 (water tank water quality detection sensor), first temperature detection component 241 (water tank temperature sensor), seventh control valve 317 (water supply three-way valve), third power component 283 (water supply pump), third one-way valve 293 (water supply one-way valve), and sixth control valve 316 (water supply valve). Heating component 220 is a heater.

[0046] The water storage tank has a capacity of approximately 50L and is used to replenish the equipment's pure water. The tank body is made of corrosion-resistant stainless steel of grade 304 or higher, welded in one piece with a wall thickness of 1.5mm or more. It features high strength, good sealing, and is not prone to rust. It is typically a fully enclosed structure to ensure water quality. The water storage tank has functions such as liquid level protection, automatic heating, and automatic water replenishment and drainage.

[0047] The high-float level gauge 202, analog level gauge 203, and low-float level gauge 204 provide level protection. The high-float level gauge 202 is installed at the high level of the water tank; when the water level rises to the set high level, it triggers a switch, sending a signal to stop water supply and prevent overflow. The analog level gauge 203 provides a continuous level signal for precise level control. The low-float level gauge 204 is installed at the low level of the water tank; when the water level drops to the set low level, it sends a signal to activate the water replenishment function, preventing the water tank from drying out. The heating element 220 heats and controls the temperature of the water in the tank. Hot water effectively removes grease, dirt, and residue from the cold plate, helping to keep the cold plate clean and prevent pipe blockage. The water tank has two drainage modes: automatic and manual. Both automatic and manual drain ports are located at the bottom of the water tank. In manual mode, the fifth control valve 315 (manual drain valve) is opened to drain water using gravity. The second power unit 282 (automatic drain pump), the second one-way valve 292 (drainage one-way valve), and the fourth control valve 314 (automatic drain valve) enable automatic drainage. When the water level in the tank reaches the set height, the fourth control valve 314 (automatic drain valve) opens, and the automatic drain pump starts to pump water out of the tank. The second one-way valve 292 (drainage one-way valve) only allows water to flow out of the tank to prevent backflow and ensure the safe and effective operation of the system. When the water level in the tank drops, the fourth control valve 314 (automatic drain valve) closes to stop drainage.

[0048] The filter element 210 (water supply filter) and differential pressure sensor perform water filtration for the main water supply pipeline. Filter element 210 is a Y-type filter, characterized by low resistance, simple structure, convenient drainage, and ease of installation and maintenance. Installed at the water pump inlet, it effectively removes solid particulate impurities from the liquid, protecting internal components such as valves, pumps, and server cooling plates from damage. A stainless steel filter screen with a filtration accuracy of 50μm is configured to effectively remove particles larger than 50μm from the liquid. The filter screen is washable and replaceable. The filter differential pressure sensor monitors the filter's operating status by measuring the pressure difference before and after the filter. When the filter element is clogged with contaminants, the resistance of the liquid passing through the filter increases, leading to an increase in differential pressure. Real-time differential pressure results are used to determine whether the filter needs replacement or cleaning.

[0049] The first power component 281 (water supply pump one) is a variable frequency water pump, which can adjust the motor speed according to actual water demand via a frequency converter, avoiding energy waste when the pump is not fully loaded, and achieving energy-saving, stable, and efficient water supply. The first one-way valve 291 (water supply one-way valve one) is a check valve used to control the unidirectional flow of fluid, allowing fluid to flow in only one direction while preventing fluid from passing through in the other direction, thus protecting the water pump and maintaining stable equipment pressure. When the pressure in the pipeline exceeds the safety set value, the second control valve 312 (pressure relief valve one) will automatically open to reduce the equipment pressure by discharging excess liquid and prevent equipment damage.

[0050] The first flow detection component 251 (water supply flow sensor one) is used to measure the liquid velocity and flow rate in the water supply pipeline to ensure that the water supply system supplies water on demand. The first pressure detection component 261 (water supply pressure sensor one) is used to monitor and regulate the pressure in the water supply pipeline to ensure stable water supply pressure, achieve constant pressure water supply, and meet water demand. The second temperature detection component 242 (water supply temperature sensor one) is used to measure the temperature of the liquid flowing through the water supply pipeline for corresponding control and regulation. The first flow detection component 251 (water supply flow sensor one), the first pressure detection component 261 (water supply pressure sensor one), and the second temperature detection component 242 (water supply temperature sensor one) are all installed on the water supply pipeline of the water storage tank. They feature high precision, high reliability, fast response speed, strong anti-interference ability, and convenient installation. Flow, pressure, and temperature parameters can all be read on the touch screen.

[0051] The filter component 210, differential pressure detection component 211, first power component 281 (water supply pump 1), first check valve 291 (water supply check valve 1), second control valve 312 (pressure relief valve 1), first flow detection component 251 (water supply flow sensor 1), first pressure detection component 261 (water supply pressure sensor 1), and second temperature detection component 242 (water supply temperature sensor 1) are used for the main water supply pipeline of the water storage tank. On the main water supply pipeline of the circulating water tank, the filter component 210, differential pressure detection component 211, first power component 281 (water supply pump 1), first check valve 291 (water supply check valve 1), second control valve 312 (pressure relief valve 1), first flow detection component 251 (water supply flow sensor 1), first pressure detection component 261 (water supply pressure sensor 1), and second temperature detection component 242 (water supply temperature sensor 1) are also installed. The water entering the server cold plate is switched through the eighth control valve 318 (water supply three-way valve).

[0052] The cleanliness testing equipment has a total of 13 branches. The first 12 branches are used for cleaning and cleanliness testing of cold-plate liquid-cooled servers, meeting a cleaning flow rate of 0-20L / min. The 13th branch is used for cleaning and cleanliness testing of cold-plate liquid-cooled cabinets, meeting a cleaning flow rate of 0-28L / min. Each of the 13 branches includes an eighth control valve 318 (water supply three-way valve), a second flow detection component 252 (branch flow sensor), a second pressure detection component 262 (server front-end pressure sensor), a third pressure detection component 263 (server rear-end pressure sensor), a first detection module 150, and a first control valve 311 (branch electric proportional valve). The second flow detection component 252 (branch flow sensor) monitors the flow rate through the server cold plates to ensure that the cleaning flow rate is within the set value. The second pressure detection component 262 (server front-end pressure sensor) and the server rear-end pressure sensor are used to monitor pressure changes before and after the server cold plate in real time, control cleaning flow and pressure, ensure stable pressure during cleaning to achieve the best cleaning effect, and avoid damage to the server cold plate. The first detection module 150 can promptly provide water quality information, thereby adjusting cleaning parameters to achieve the best cleaning effect. By monitoring the pH, conductivity, and turbidity of the water quality in real time, it ensures that the water after cleaning the server cold plate meets the standards, avoiding poor cleaning results due to water quality issues. The first control valve 311 (branch electric proportional valve) precisely adjusts the valve opening according to the control signal, thereby achieving precise control of the liquid flow. The electric proportional valve has a fast response time and can continuously and quickly adjust the flow to adapt to the rapid changes in liquid control requirements during the cleaning process. Branch flow, pressure, and water quality parameters can all be read and set on the touch screen.

[0053] The fourth pressure detection component 264 (return water pressure sensor) is used to monitor pressure changes in the return water pipeline to ensure that the equipment operates within a safe working pressure range.

[0054] The second detection module 160 (water tank water quality detection sensor) is used to monitor the water quality parameters of the storage tank, including pH, conductivity, and turbidity, to ensure that the water entering the server cold plate meets the liquid cooling industry standards and prevent the cold plate from being contaminated by water and causing corrosion. The first temperature detection component 241 (water tank temperature sensor) is used to monitor the temperature of the water in the storage tank for corresponding control and adjustment, while preventing the heating component 220 from dry burning.

[0055] The water tank has two water replenishment modes. Both water inlets are located in the upper part of the tank. The third power unit 283 (water replenishment pump) and the third one-way valve 293 (water replenishment check valve) enable the equipment's built-in water pump to replenish water. When the water level in the tank reaches the low level, the seventh control valve 317 (water replenishment three-way valve) opens, and the third power unit 283 (water replenishment pump) starts to replenish water into the tank. The third one-way valve 293 (water replenishment check valve) only allows water to flow from the outside into the tank to prevent backflow and ensure the safe and effective operation of the system. When the water level in the tank rises to the set height, the third power unit 283 (water replenishment pump) and the seventh control valve 317 (water replenishment three-way valve) close, stopping water replenishment. External pressurized water replenishment can be carried out using the sixth control valve 316 (water replenishment valve).

[0056] The high-float level gauge 202, analog level gauge 203, low-float level gauge 204, heating element 220, second detection module 160 (water tank water quality detection sensor), and first temperature detection element 241 (water tank temperature sensor) are used in the water storage tank, and the same configuration is also used in the first liquid storage component 110 (circulating water tank). The fifth control valve 315 (manual drain valve), second power component 282 (automatic drain pump), second one-way valve 292 (drain one-way valve), fourth control valve 314 (automatic drain valve), seventh control valve 317 (water replenishment three-way valve), third power component 283 (water replenishment pump), third one-way valve 293 (water replenishment one-way valve), and sixth control valve 316 (water replenishment valve) are shared by the water storage tank and the first liquid storage component 110 (circulating water tank).

The equipment uses a water pump to deliver pure water and continuously introduces pure water into the server cold plate through the connecting pipeline for cleaning. First, water from the circulating water tank is used for preliminary cleaning, and then water from the storage tank is used for thorough cleaning to ensure that the residue inside the cold plate can be removed.

[0062] Cleanliness testing:

[0063] Different server models have different cleaning parameters, which are assigned by scanning the server's QR code. When the assigned cleaning parameters are met, the cleaning of the cold plate piping of the server under test is completed, and cleanliness testing begins. Water quality sensors capture the water quality parameters flowing out of the server, and the test results are compared with the set water quality standards to determine the cleaning effect.

[0068] To reduce operation and maintenance costs, the testing equipment of this application has a highly automated testing process, which can automatically complete the pre-test preparation, testing process, and post-test data processing and report generation. This not only reduces the need for manual operation and reduces labor costs, but also improves testing efficiency and further reduces operation and maintenance costs.

[0069] Ensuring stable server operation is crucial for efficient data center maintenance. Timely and accurate detection of the internal cleanliness of liquid-cooled cold plate servers allows for the timely identification and handling of potential contamination issues, preventing contaminants from affecting server heat dissipation efficiency.

[0070] Extending server lifespan requires a clean working environment, which is crucial for the long-term stable operation of electronic equipment.

[0072] To improve user experience, the testing equipment in this application provides a convenient and efficient solution that can monitor and evaluate the cleanliness of servers in real time, providing strong support for operation and maintenance decisions, helping to improve user experience, and enhancing user satisfaction and trust in data center services.

[0073] High-precision sensor technology is used to capture signals, enabling accurate detection of minute contaminants inside cold-plate liquid-cooled servers. Non-contact detection is performed without touching the server's interior, avoiding physical damage to internal components. Combining pure water cleaning with cleanliness testing forms a complete and comprehensive cleanliness testing solution after aging tests of cold-plate liquid-cooled servers, accurately evaluating the improvement effect of pure water cleaning on the server's internal cleanliness.
