[0075] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0076] A large number of microorganisms carried in the cold plate pipeline 2 enter the liquid cooling circulation system of the data center, causing a sharp increase in the number of microorganisms. The acidic substances and microbial mud produced by them will cause coolant pollution and blockage and damage to the circulation pipeline. In order to avoid system damage caused by coolant pollution, the normal operation of the system can only be ensured by thoroughly cleaning the cooling pipeline and replacing all the coolants, resulting in a large amount of manpower and material resources. Waste; Since the internal cleanliness of the cold plate pipeline 2 cannot be effectively detected and quantified, in most cases, the cleanliness of the cold plate pipeline 2 is detected by naked eye observation, which makes the operation difficult and intensive for operators; and due to the lack of judgment on whether the cold plate pipeline 2 is blocked, operators are prone to mistakenly connect the blocked cold plate pipeline 2 directly to the liquid cooling circulation system of the data center, thereby causing damage to the pipeline.
[0077] Combine the following Figures 1 to 12 , describing an embodiment of the present invention.
[0078] According to an embodiment of the present invention, a cleaning detection system 1 for a cold plate pipeline 2 is provided, comprising a detection system 1, a liquid supply system 3 and a control system; the detection system 1 comprises a cleaning pipeline 11 and a cleanliness detection structure 12, the cleaning pipeline 11 comprises a first cleaning branch 111 and a second cleaning branch 112, the first cleaning branch 111 is connected to the liquid inlet end of the cold plate pipeline 2, the second cleaning branch 112 is suitable for being connected to the liquid outlet end of the cold plate pipeline 2, and the cleanliness detection structure 12 is arranged on the second cleaning branch 112; the liquid supply system 3 is connected to the first cleaning branch 111, and is suitable for continuously conveying liquid into the cold plate pipeline 2 to clean the cold plate pipeline 2; the control system is connected to both the cleanliness detection structure 12 and the liquid supply system 3, receives the cleanliness data transmitted by the cleanliness detection structure 12, and controls the start and stop of the liquid supply system 3 according to the cleanliness data.
[0079] By arranging the cold plate pipeline 2 between the first cleaning branch 111 and the second cleaning branch 112, the liquid supply system 3 continuously transports liquid into the cold plate pipeline 2 through the first cleaning branch 111 to flush the cold plate pipeline 2, thereby achieving flushing, cleaning and cleaning of the cold plate pipeline 2; since the cleaned liquid needs to flow through the second cleaning branch 112, the cleanliness detection structure 12 is arranged on the second cleaning branch 112, thereby achieving the detection of the cleanliness of the liquid flowing through the cold plate pipeline 2. Through the mutual cooperation of the detection system 1, the liquid supply system 3 and the control system, the effective detection and quantitative output of the cleanliness of the cold plate pipeline 2 are achieved, and at the same time, the cleaning operation of the cold plate pipeline 2 is achieved, thereby avoiding the metal powder carried by the cold plate pipeline 2. Various impurities and pollutants such as chips and welding slag enter the liquid cooling circulation system of the data center, preventing various impurities and pollutants from causing problems such as coolant contamination or component blockage in the liquid cooling circulation system of the data center, thereby avoiding the problem of pipeline damage caused by coolant contamination; and realizing the active flushing and removal function of microorganisms attached to the cold plate pipeline 2, avoiding the problem of excessive coolant microorganisms when the cold plate pipeline 2 is connected to the liquid cooling circulation pipeline of the data center, avoiding a large amount of coolant discharge waste caused by the overall replacement of the coolant, and the environmental pollution caused by the coolant discharge; reducing the waste of manpower and material resources required for replacing the coolant and pipeline components; effectively improving the use safety, stability and operation efficiency of the liquid cooling circulation system of the data center.
[0080] In a specific embodiment, when the cleanliness detection structure 12 detects that the cleanliness of the liquid in the second clean branch 112 meets the requirements, it means that the cleanliness inside the cold plate pipeline 2 meets the requirements. At this time, the control system can control the liquid supply system 3 to shut down and stop continuing to transport liquid to the cold plate pipeline 2; when it is detected that the cleanliness of the liquid in the second clean branch 112 does not meet the requirements, it means that the cleanliness inside the cold plate pipeline 2 still does not meet the requirements. At this time, the control system can control the liquid supply system 3 to continue to transport liquid to the cold plate pipeline 2, and continue to flush and clean the cold plate pipeline 2 until it is detected that the cleanliness inside the cold pipe pipeline meets the requirements.
[0081] In a specific embodiment, the cleanliness detection structure 12 includes a first conductivity sensor 121, a first turbidity sensor 122 and a first pH meter 123. The first conductivity sensor 121, the first turbidity sensor 122 and the first pH meter 123 can respectively detect the water quality of the liquid in the second clean branch 112, thereby completing the cleanliness detection of the cold plate pipeline 2.
[0082] In one embodiment, it also includes a liquid storage system 4, which includes a high-temperature water liquid storage device 41 and a pure water liquid storage device 42; the high-temperature water liquid storage device 41 includes a first water outlet pipeline 411, and a first on-off component 412 is provided on the first water outlet pipeline 411; the pure water liquid storage device 42 includes a second water outlet pipeline 421, and a second on-off component 422 is provided on the second water outlet pipeline 421; the liquid supply system 3 includes a liquid supply pipeline, and the first water outlet pipeline 411 and the second water outlet pipeline 421 are both connected to the liquid inlet end of the liquid supply pipeline; the control system is connected to the first on-off component 412 and the second on-off component 422, and controls the on-off of the first water outlet pipeline 411 by controlling the first on-off component 412, or controls the on-off of the second water outlet pipeline 421 by controlling the second on-off component 422.
[0083] By cooperating with the control system and the first on-off component 412 and the second on-off component 422, the switching process between high-temperature water and pure water is realized, which is convenient for switching the liquid supply source according to the use needs of the equipment; when cleaning the cold plate pipeline 2, the control system first controls the first on-off component 412 to connect the first water outlet pipeline 411, and controls the second on-off component 422 to disconnect the second water outlet pipeline 421, and then the high-temperature water infusion device supplies high-temperature water to the liquid supply system 3 to flush and clean the cold plate pipeline 2. After the warm water circulation is completed, the control system controls the first on-off component 412 to disconnect the first water outlet pipe 411, and controls the second on-off component 422 to connect the second water outlet pipe 421, and then the pure water storage device 42 supplies pure water to the liquid supply system 3 to deeply clean the cold plate pipe 2; first, high-temperature water is used for flushing and cleaning, and the thermal energy of high-temperature water is used to enhance the cleaning power, deeply disintegrate and peel off impurities and microorganisms, and then pure water is used for flushing and cleaning to completely remove residual impurities and microorganisms, thereby improving the cleaning quality and efficiency of the cold plate pipe 2.
[0084] Preferably, a filter is provided at the inlet end of the first water outlet pipe 411 and the second water outlet pipe 421 to filter solid impurities that may be contained in the liquid entering the first water outlet pipe 411 and the second water outlet pipe 421, thereby avoiding blockage of the first water outlet pipe 411 and the second water outlet pipe 421 during use and ensuring the normal operation of the system.
[0085] In a specific implementation, the cleanliness detection structure 12 detects the water quality changes of the disposable pure water flowing through the cold plate pipeline 2 to complete the cleanliness detection of the cold plate pipeline 2, which can truly simulate the impact of the cold plate pipeline 2 on water quality under actual working conditions.

[0087] By adjusting the opening of the first liquid supply proportional valve 4121 through the control system, the on-off control of the first pipeline is realized; the setting of the first flow sensor 4122 facilitates real-time monitoring of the liquid flow in the first liquid outlet pipeline; the setting of the first check valve 4123 can ensure the unidirectional flow of the liquid in the first water outlet pipeline 411, and prevent the contamination of the liquid in the high-temperature water storage device 41 caused by liquid return.
[0088] In one embodiment, the second on-off component 422 includes a second liquid supply proportional valve 4221, a second flow sensor 4222 and a second one-way valve 4223; the second liquid supply proportional valve 4221 is connected to the control system, and the control system is suitable for controlling and adjusting the valve opening of the second liquid supply proportional valve 4221; the second flow sensor 4222 is arranged on the side of the second liquid supply proportional valve 4221 close to the liquid supply pipeline, and is connected to the control system to transmit the liquid flow data in the second water outlet pipeline 421 to the control system; the second one-way valve 4223 is arranged on the side of the second flow sensor 4222 close to the liquid supply pipeline.
[0089] By adjusting the opening of the second liquid supply proportional valve 4221 through the control system, the on-off control of the second pipeline is realized; the setting of the second flow sensor 4222 facilitates real-time monitoring of the liquid flow in the second liquid outlet pipeline; the setting of the second check valve 4223 can ensure the unidirectional flow of the liquid in the second water outlet pipeline 421, and prevent the contamination of the liquid in the high-temperature water storage device 41 caused by liquid return.
[0090] In one embodiment, the liquid supply system 3 further includes a liquid supply cleaning device, which includes a liquid supply sterilization structure 31 and a liquid supply filtering structure 32. The liquid supply sterilization structure 31 and the liquid supply filtering structure 32 are sequentially arranged on the liquid supply pipeline.
[0091] By arranging a liquid supply cleaning device on the liquid supply pipeline, the liquid inside the liquid supply pipeline can be cleaned; by arranging a liquid supply sterilization structure 31, the microorganisms and bacteria in the liquid entering the liquid supply pipeline can be actively disinfected, thereby preventing the occurrence of problems such as contamination and corrosion damage of the cold plate pipeline 2 caused by excessive microorganisms and bacteria in the liquid inside the liquid supply pipeline; by arranging a liquid supply filtering structure 32, the liquid entering the liquid supply pipeline can be filtered, and impurities such as suspended particles in the liquid inside the liquid supply pipeline can be effectively removed, thereby preventing impurities such as suspended particles in the liquid inside the liquid supply pipeline from causing blockage of the cold plate pipeline 2.
[0092] Specifically, the liquid supply sterilization structure 31 adopts ultraviolet sterilization technology.
[0093] In one embodiment, the liquid supply filter structure 32 includes a liquid supply filter state detection unit 321 and a liquid supply filter pipeline 322; the liquid supply filter state detection unit 321 includes a liquid supply inlet pressure sensor 3211 and a liquid supply outlet pressure sensor 3212, and the liquid supply inlet pressure sensor 3211 and the liquid supply outlet pressure sensor 3212 are arranged on the liquid supply pipeline in sequence; the liquid supply filter pipeline 322 is located between the liquid supply inlet pressure sensor 3211 and the liquid supply outlet pressure sensor 3212, and is connected to the liquid supply pipeline; and a liquid supply filter 323 is provided on the liquid supply filter pipeline 322; the liquid supply inlet pressure sensor 3211 and the liquid supply outlet pressure sensor 3212 are both connected to the control system, and transmit the inlet pressure and the outlet pressure to the control system, and the control system determines the filter element state of the liquid supply filter 323 by the difference between the inlet pressure and the outlet pressure.
[0094] By setting up a liquid supply filter 323 on the liquid supply filter pipeline 322, the removal of impurities such as suspended particles in the liquid supply liquid is achieved to ensure that the water quality of the liquid supply liquid meets the use requirements of the cleanliness detection of the cold plate pipeline 2; the state of the liquid supply filter 323 is determined by the difference between the inlet pressure and the outlet pressure. When the pressure difference between the two is greater than the set value, the control system automatically reminds the relevant maintenance personnel to clean and replace the filter element of the liquid supply filter 323.
[0095] Specifically, the effective removal rate of suspended particles of the liquid supply filter structure 32 is as high as 99%.
[0096] Specifically, the liquid supply filter 323 is designed with a stainless steel flushable filter element.
[0097] In one embodiment, at least two liquid supply filter pipelines 322 are provided, and at least two liquid supply filter pipelines 322 are arranged in parallel; the liquid supply filter pipeline 322 is also provided with a liquid supply inlet valve 324 and a liquid supply outlet valve 325, the liquid supply inlet valve 324 is arranged on the side where the inlet of the liquid supply filter 323 is located, and the liquid supply outlet valve 325 is arranged on the side where the outlet of the liquid supply filter 323 is located.
[0098] The liquid supply inlet valve 324 and the liquid supply outlet valve 325 cooperate to realize the on-off of the liquid supply filter pipeline 322. By setting up at least two liquid supply filter pipelines 322, a dual liquid supply filter pipeline 322 design of one for use and one for backup is realized, and the filter element can be cleaned and replaced and the pipeline can be maintained without shutting down the system.
[0099] In one embodiment, a liquid supply sampling valve 326 is further provided on the liquid supply filtering pipeline 322 , and the liquid supply sampling valve 326 is arranged at one end where the outlet of the liquid supply filter 323 is located.
[0100] The liquid supply sampling valve 326 is provided to discharge the liquid in the liquid supply filter pipeline 322, and to complete a convenient sampling operation of the liquid supply, thereby realizing the sampling and inspection of the liquid supply without stopping the machine.
[0101] In one embodiment, the liquid supply system 3 further includes a power structure 33 , and the power structure 33 includes a power pipeline 331 , and the power pipeline 331 is connected to the liquid supply pipeline.
[0102] By arranging the power structure 33 in the liquid supply system 3 , power is provided for the liquid in the liquid supply pipeline, thereby ensuring that the liquid in the liquid supply pipeline can flow smoothly to the cold plate pipeline 2 .
[0103] In one embodiment, a driving pump 332, an inlet shock absorber pipe 333 and an outlet shock absorber pipe 334 are provided on the power pipeline 331. The inlet shock absorber pipe 333 is arranged on the side where the inlet of the driving pump 332 is located; the outlet shock absorber pipe 334 is arranged on the side where the outlet of the driving pump 332 is located.
[0104] The provision of the inlet shock-absorbing pipe 333 and the outlet shock-absorbing pipe 334 eliminates the installation error of the driving pump 332 and the power pipeline 331 when the driving pump 332 is installed on the power pipeline 331, and reduces the vibration impact when the driving pump 332 is running.
[0105] In a specific implementation, the driving pump 332 adopts a variable frequency motor drive design, which can automatically adjust the motor speed according to the liquid flow and pressure required by the cold plate pipeline 2 to achieve on-demand operation, thereby achieving energy-saving operation of the system.
[0106] In one embodiment, at least two groups of power pipelines 331 are provided, and at least two groups of power pipelines 331 are arranged in parallel; a power inlet valve 335 and a power outlet valve 336 are also provided on the power pipeline 331, and the power inlet valve 335 is arranged at the end where the inlet of the power pipeline 331 is located, and the power outlet valve 336 is arranged at the end where the outlet of the power pipeline 331 is located.
[0107] The power inlet valve 335 and the power outlet valve 336 cooperate to realize the on-off of the power pipeline 331. By setting up at least two groups of power pipelines 331, one power pipeline 331 is used and the other is reserved. When one of the power pipelines 331 has a problem and needs to be shut down for maintenance, the other power pipeline 331 can still operate normally, thereby ensuring the normal operation of the system. In addition, during the operation of the system, the control system can also control at least two groups of power pipelines 331 to be used alternately, thereby avoiding the occurrence of problems such as overheating, thermal attenuation, efficiency reduction and service life reduction of the drive pump 332 motor due to long-term operation of a single power pipeline 331, thereby effectively improving the service life and work efficiency of the drive pump 332.
[0108] In one embodiment, a third one-way valve 337 is further provided on the power pipeline 331 , and the third one-way valve 337 is arranged at one end where the outlet of the outlet shock absorber pipe 334 is located.
[0109] The third one-way valve 337 is provided to prevent the liquid outputted by the driving pump 332 from flowing back, thereby avoiding the problem of a decrease in the driving force of the driving pump 332 caused by the liquid flowing back.
[0110] In one embodiment, the liquid supply system 3 further includes a safety valve 34 , which is located at one end of the outlet of the power pipeline 331 and is arranged on the liquid supply pipeline.
[0111] By setting the safety valve 34, when the system encounters sensor failure or abnormal valve closure, it can avoid the drive pump 332 from continuously running, causing overpressure in the power pipeline 331 and then causing pipeline rupture, water drive pump 332 and other situations.
[0112] Specifically, the safety valve 34 can set a suitable safety relief pressure according to the system operation conditions. When the pressure of the power line 331 exceeds the set safety relief pressure, the safety valve 34 can use a dedicated line to discharge and relieve pressure, thereby ensuring the safe operation of the system.
[0113] In one embodiment, the liquid supply system 3 also includes a liquid supply detection structure 35, which is located at one end where the outlet of the power pipeline 331 is located, is arranged on the liquid supply pipeline, and is connected to the control system; the liquid supply detection structure 35 is used to detect and feedback the liquid state output by the power pipeline 331 to the control system.
[0114] By setting up the liquid supply detection structure 35 to detect and feed back the liquid state output by the power pipeline 331 to the control system, it is convenient for the control system to make corresponding control adjustments to other structures of the cleaning detection system 1 for the cold plate pipeline 2 to ensure the normal operation of the system.
[0115] Specifically, the liquid supply detection structure 35 includes a liquid supply flow meter 351, a liquid supply temperature sensor 352, and a liquid supply pressure sensor 353. The liquid supply flow meter 351, the liquid supply temperature sensor 352, and the liquid supply pressure sensor 353 can be used to detect equipment operation-related parameters such as liquid flow, temperature, and pressure output by the power pipeline 331, respectively.
[0116] Specifically, the liquid supply pressure sensor 353 adopts a one-in-use and one-in-standby design.
[0117] In one embodiment, the liquid supply system 3 also includes a liquid supply flow regulating branch 36, which is located at one end of the outlet of the power pipeline 331 and is connected to the liquid supply pipeline; and an electric control valve 361 is provided on the liquid supply flow regulating branch 36, and the electric control valve 361 is connected to the control system. The control system controls the valve opening of the electric control valve 361 according to the liquid flow and pressure required by the cold plate pipeline 2.
[0118] Through the setting of the liquid supply flow regulating branch 36, when the required flow and pressure of the cold plate pipeline 2 to be tested are lower than the minimum output flow of the driving pump 332, the short-circuit bypass operation is achieved by adjusting the opening of the electronically controlled proportional valve; and at the same time, the liquid supply flow regulating branch 36 can also cooperate with the cleaning pipeline 11 where the cold plate pipeline 2 is located to perform intelligent adjustment of the specified flow and pressure of the cleaning pipeline 11.
[0119] In one embodiment, the detection system 1 also includes a pressure state detection unit 13, which includes a front pressure sensor 131 and a rear pressure sensor 132. The front pressure sensor 131 is arranged on the first cleaning branch 111, and the rear pressure sensor 132 is arranged on the second cleaning branch 112; the front pressure sensor 131 and the rear pressure sensor 132 are both connected to the control system and transmit the front pressure and the rear pressure to the control system. The control system determines the state of the cold plate pipeline 2 by the difference between the front pressure and the rear pressure.
[0120] By setting the front pressure sensor 131 and the rear pressure sensor 132, the reading of the inlet and outlet pressure values of the cold plate pipeline 2 can be completed, and the pressure drop and flow resistance determination monitoring output operation of the cold plate pipeline 2 can be completed by comparing the difference between the inlet pressure and the outlet pressure of the cold plate pipeline 2, and the feedback is given to the equipment control system. The control system adjusts the required pressure drop of the cold plate pipeline 2 by adjusting the flow and pressure of the cleaning pipeline 11 according to the specific needs of the cold plate pipeline 2. At the same time, the control system can determine the blockage state of the cold plate pipeline 2 according to the pressure drop and flow resistance values of the cold plate pipeline 2, thereby avoiding the liquid-cooled server equipped with a blocked cold plate pipeline 2 from being powered on and connected to the system, causing burn-in damage to the liquid-cooled server.
[0121] In one embodiment, at least two groups of cleaning pipelines 11 are provided, and the at least two groups of cleaning pipelines 11 are arranged in parallel. The cleaning pipelines 11 are provided with on-off valves 14 , and the on-off valves 14 are arranged at one end close to the opening of the cleaning pipeline 11 .
[0122] By setting up at least two groups of cleaning pipelines 11, the cleanliness detection and improvement operation of multiple cold plate pipelines 2 is realized; the setting of the on-off valve 14 realizes the overall on-off of the corresponding cleaning pipeline 11 to achieve the normal operation of the cleaning pipeline 11, and at the same time, the liquid supply can be shut off when the relevant parts on the cleaning pipeline 11 are maintained.
[0123] Specifically, the on-off valve 14 is an electric switch valve.
[0124] In one embodiment, a third flow sensor 15 is further provided on the cleaning pipeline 11 . The third flow sensor 15 is connected to the control system to transmit liquid flow data in the cleaning pipeline 11 to the control system.
[0125] By setting up the third flow sensor 15, the detection of the liquid flow in the cleaning pipeline 11 is realized, and the relevant flow data information can be uploaded to the control system in real time, so that the operator can monitor in real time whether the liquid flow flowing through the cold plate pipeline 2 meets the specific usage requirements, and complete the adjustment of the required flow according to the specific needs of the cold plate pipeline 2.
[0126] In one embodiment, a constant pressure regulating valve 16 is further provided on the cleaning pipeline 11 , and the constant pressure regulating valve 16 is connected to a control system, and the control system controls the valve opening of the constant pressure regulating valve 16 according to the liquid flow and pressure required by the cold plate pipeline 2 .
[0127] By setting a constant pressure regulating valve 16, intelligent adjustment of the pressure and flow of the cleaning pipeline 11 can be achieved. The control system controls the valve opening of the constant pressure regulating valve 16 according to the liquid flow and pressure required by the cold plate pipeline 2, so that the corresponding cleaning pipeline 11 meets the use requirements of the cold plate pipeline 2.
[0128] Specifically, the constant pressure regulating valve 16 adopts an electric proportional regulation design, and can intelligently adjust its opening parameters according to the flow rate and pressure required by the cold plate pipeline 2.
[0129] In one embodiment, a buffer box 17 is further provided on the cleaning pipeline 11 , and the cleanliness detection structure 12 is disposed on the buffer box 17 .
[0130] By providing the buffer box 17 , the flow rate of the liquid passing through can be reduced, so as to improve the detection accuracy of the cleanliness detection structure 12 .
[0131] In one embodiment, the detection system 1 further includes a first liquid discharge structure, which is connected to the cleaning pipeline 11 and is used for draining the cleaning pipeline 11 and clearing the cleanliness detection structure 12 .
[0132] By setting the first drainage structure, when the cold plate pipeline 2 is cleaned, the drainage function of the cleaning pipeline 11 is realized to prevent the pipeline corrosion caused by the growth of microorganisms in the coolant in the cold plate pipeline 2 for a long time. At the same time, the cleanliness detection structure 12 can be reset to facilitate the recycling of the cleaning detection system 1 for the cold plate pipeline 2, thereby avoiding the cleanliness detection result of the cold plate pipeline 2 being affected by the previous detection result.
[0133] Specifically, the first liquid discharge structure includes a first liquid discharge branch and a second liquid discharge branch. The inlet of the first liquid discharge branch is connected to the outside compressed air, and the outlet is arranged at the outlet side of the on-off valve 14 and is connected to the first cleaning branch 111. The air inlet switch valve 181 and the air inlet check valve 182 are arranged on the first liquid discharge branch. The inlet of the second liquid discharge branch is arranged on the inlet side of the constant pressure regulating valve 16 and is connected to the second cleaning branch 112.
