Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0036] In conjunction with the specific application environment architecture or specific hardware architecture on which the execution of the liquid cooling server leakage detection method depends, the specific application environment architecture or specific hardware architecture is described herein.
[0037] The embodiment of the present application provides a state recovery circuit, and describes the method in detail in conjunction with the execution flow of the state recovery circuit.
[0038] Figure 1 A schematic diagram of a liquid cooling server leakage detection device provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the liquid cooling server leakage detection device includes: a leakage transmission module and a leakage detection module.
[0039] The liquid leakage transmission module is located below the liquid cooling system of the liquid cooling server, and the liquid leakage detection module is located below the liquid leakage transmission module.
[0040] A liquid-cooled server is a server that uses liquid cooling for thermal management. It uses a liquid cooling system to remove the heat generated by computing components to achieve the purpose of cooling. A liquid cooling system generally includes coolant, pumps, pipes, radiators, and other parts. The leakage transmission module is a device used to convert non-conductive coolant into conductive liquid and transmit the conductive coolant to the leakage detection module. The leakage transmission module is located below the liquid cooling system and can respond in time when the coolant leaks and transmit the leaked coolant to the detection module. The leakage detection module is an equipment module responsible for monitoring leakage. It is located below the leakage transmission module and is used to detect the arrival of conductive coolant and determine whether a leakage has occurred, thereby triggering a leakage alarm message through a level change.
[0041] The leakage transfer module is installed in the lower area of the liquid cooling system of the liquid-cooled server to ensure that its coverage can be as wide as possible to receive the coolant that may drip from different positions of the liquid cooling system. For example, the leakage transfer module will be laid at a suitable angle or in a flat manner so that once the non-conductive coolant contacts the module, it can be converted and transferred along the preset path.
[0042] The liquid leakage detection module is installed in the lower area of the liquid leakage transmission module, and there is a certain distance between the liquid leakage detection module and the liquid leakage transmission module. The specific value of the distance is not limited in the embodiments of the present application to facilitate the smooth transmission of the conductive coolant. When the non-conductive coolant accidentally drips onto the liquid leakage transmission module, the liquid leakage transmission module converts the originally non-conductive coolant into a conductive coolant. Subsequently, by means of gravity or the guiding structure of the liquid leakage transmission module itself, such as a specific flow channel design, the conductive coolant is transmitted to the position where the liquid leakage detection module is located. The liquid leakage detection module is always in a monitoring state, and the detection elements inside it can sensitively sense the change in the liquid leakage detection level. Once the conductive coolant arrives and the level changes, the module will immediately trigger the corresponding alarm program and clearly convey the liquid leakage alarm information to the outside world through lights, sounds, or data signals, etc., to ensure that relevant personnel can detect it in time and take corresponding measures.
[0043] By arranging the liquid leakage transmission module below the liquid cooling system, it can receive the liquid leakage from all parts of the liquid cooling system in all directions, avoiding the missed detection problem caused by incomplete line coverage in the traditional detection method, and greatly improving the accuracy and comprehensiveness of liquid leakage detection. The layered layout of the liquid leakage transmission module and the liquid leakage detection module makes the structure of the entire detection device more reasonable and compact, facilitating the installation, maintenance, and replacement of components, and at the same time reducing the failure risk that may be caused by the complex interlacing of components.
[0044] The liquid leakage transmission module is used to convert the non-conductive coolant into a conductive coolant if the non-conductive coolant in the liquid cooling system drops onto the liquid leakage transmission module.
[0045] The non-conductive coolant refers to the insulating cooling medium used in the liquid cooling system. For example, mineral oil, fluorinated liquid, pure water, deionized water, etc. cannot directly trigger the detection circuit through electrical signals. The conductive coolant has its conductivity increased by adding conductive substances, such as containing sodium ions, containing carbon nanotubes, etc., and can generate detectable level changes by conducting the circuit. Conversion refers to the process of changing the conductive characteristics of the non-conductive coolant through physical or chemical means, making it change from an insulating state to a conductive state.
[0046] By converting the non-conductive coolant into a conductive coolant, the liquid leakage transmission module can ensure that the coolant leakage can be effectively detected by the liquid leakage detection module. This conversion process makes the liquid leakage detection more reliable and prevents the liquid leakage from not being detected in time due to the insulating property of the coolant.
[0047] The liquid leakage transmission module is also used to transmit the conductive coolant to the liquid leakage detection module.
[0048] When a non-conductive coolant accidentally drips onto the liquid leakage transmission module, a pre-set conversion mechanism inside the module (such as specific chemical reaction substances or physical structures) will quickly come into play, converting the originally non-conductive coolant into a conductive coolant. Subsequently, with the help of gravity or the module's own guiding structure, such as a specific flow channel design, the conductive coolant is accurately transmitted to the location of the liquid leakage detection module.
[0049] The layered layout of the liquid leakage transmission module and the liquid leakage detection module makes the structure of the entire detection device more reasonable and compact, facilitating installation, maintenance, and component replacement. At the same time, it also reduces the risk of failures that may be caused by complex component intersections.
[0050] The liquid leakage detection module is used to monitor whether the liquid leakage detection level changes. The liquid leakage detection level changes when the liquid leakage detection module receives the conductive coolant.
[0051] The liquid leakage detection level is a level reference value inside the liquid leakage detection module for judging whether liquid leakage has occurred. Under normal circumstances, the liquid leakage detection level remains in the set initial state. When the conductive coolant contacts the detection module, causing the circuit to conduct, the liquid leakage detection level will change accordingly.
[0052] By the real-time monitoring of the liquid leakage detection level by the liquid leakage detection module, it is possible to judge whether the liquid-cooled server has a liquid leakage situation, improving the timeliness and accuracy of liquid leakage detection, and effectively avoiding potential risks such as server overheating and damage caused by the failure to detect liquid leakage in a timely manner.
[0053] The liquid leakage detection module is used to output a liquid leakage warning message if it monitors that the liquid leakage detection level has changed.
[0054] The liquid leakage warning message refers to a prompt signal output when the liquid leakage detection module monitors that the liquid leakage detection level has changed and determines that there is a liquid leakage situation in the liquid-cooled server. This prompt signal can be in various forms such as electrical signals, optical signals, and sound signals, and is used to remind maintenance personnel to handle the liquid leakage problem in a timely manner to ensure the normal operation of the server.
[0055] Through the output liquid leakage warning message, the system can provide real-time feedback on the state of coolant leakage, providing clear fault information for operators, facilitating quick fault location and handling. It improves the efficiency of repair and maintenance and reduces human intervention and misjudgment.
[0056] Through the present application, by providing a liquid leakage transmission module located below the liquid cooling system and a liquid leakage detection module located below the liquid leakage transmission module, the liquid leakage transmission module can convert the non-conductive coolant that drops onto it into conductive coolant and transmit it to the liquid leakage detection module. The liquid leakage detection module outputs a liquid leakage warning message by monitoring the change in the liquid leakage detection level, thereby achieving a comprehensive detection of the liquid leakage situation of the liquid cooling system, expanding the coverage of liquid leakage detection, and improving the accuracy of liquid leakage detection of the liquid-cooled server. Therefore, the technical problem of low accuracy of liquid leakage detection of the liquid-cooled server can be solved, and the technical effect of improving the accuracy of liquid leakage detection of the liquid-cooled server can be achieved.
[0057] In some embodiments, please continue to refer to Figure 1 , the liquid leakage transmission module includes: a liquid leakage converter and a liquid leakage collector;
[0058] The liquid leakage converter is located below the liquid cooling system;
[0059] The liquid leakage collector is located below the liquid leakage converter;
[0060] The liquid leakage converter is configured to, if non-conductive coolant drops onto the liquid leakage converter, convert the non-conductive coolant into conductive coolant and transmit the conductive coolant to the liquid leakage collector;
[0061] The liquid leakage collector is configured to receive the conductive coolant transmitted by the liquid leakage converter and transmit the conductive coolant to the liquid leakage detection module.
[0062] The liquid leakage converter is a conversion device located below the liquid cooling system. When non-conductive coolant drops onto its surface, it can convert the non-conductive coolant into conductive coolant. The liquid leakage converter changes the conductivity of the coolant through a certain chemical reaction or physical process, making it have conductivity that can be recognized by the liquid leakage detection module. The liquid leakage collector is located below the liquid leakage converter. The liquid leakage collector receives the conductive coolant transmitted by the liquid leakage converter and conveys it to the liquid leakage detection module. The liquid leakage collector ensures the effective transmission of the conductive coolant and provides the necessary physical medium for the liquid leakage detection module to further perform liquid leakage detection.
[0063] When the non-conductive coolant in the liquid cooling system leaks and drops onto the surface of the liquid leakage converter, the chemical components or physical design in the liquid leakage converter will cause the coolant to come into contact with certain reaction substances. The reaction substances can make the originally non-conductive coolant become conductive through electrolytic reaction or ion exchange, etc. The liquid leakage collector receives the conductive coolant transmitted by the liquid leakage converter. The internal design of the liquid leakage collector is usually a container or pipeline system with a certain capacity, which can store and transmit the converted conductive coolant.
[0064] The liquid leakage transmission module can make the coolant easier to be recognized by the liquid leakage detection module by converting the non-conductive coolant into a conductive coolant. This greatly improves the sensitivity of the system to coolant leakage, ensuring that the liquid leakage detection module can detect problems in a timely manner when coolant leakage occurs.
[0065] In some embodiments, please continue to refer to Figure 1 , the liquid leakage converter includes: a conductive ion paper;
[0066] The conductive ion paper contains conductive ions;
[0067] The conductive ion paper is used to integrate the conductive ions into the non-conductive coolant to obtain a conductive coolant if the non-conductive coolant drops onto the conductive ion paper;
[0068] The conductive ion paper is also used to penetrate the conductive coolant out of the conductive ion paper by gravity;
[0069] The liquid leakage collector is also used to receive the penetrated conductive coolant.
[0070] The conductive ion paper is a special paper that contains conductive ions inside. When the non-conductive coolant drops onto the conductive ion paper, the conductive ions can integrate into the coolant, turning it into a conductive coolant. At the same time, the conductive ion paper has a certain permeability, and under the action of gravity, it can allow the conductive coolant to penetrate out smoothly for subsequent collection and transmission.
[0071] When the non-conductive coolant in the liquid cooling system drops onto the conductive ion paper due to a fault, the coolant will wet the surface of the conductive ion paper. At this time, the conductive ions in the conductive ion paper start to be activated and gradually integrate into the non-conductive coolant. As the conductive ions continue to integrate, the electrical properties of the original non-conductive coolant change and gradually turn into a conductive coolant. Under the action of gravity, the conductive coolant will gradually penetrate out of the conductive ion paper. The permeability of the conductive ion paper is specially designed to ensure that the conductive coolant flows out smoothly without excessive accumulation inside the paper. The penetrated conductive coolant will drip into the liquid leakage collector located below it.
[0072] The design of the conductive ion paper makes the entire liquid leakage conversion process simple and direct, without the need for complex mechanical structures or additional power sources, reducing the complexity and cost of the equipment. At the same time, it also improves the stability and reliability of the system, reducing the risk of liquid leakage detection failure caused by equipment failure.
[0073] In some embodiments, please continue to refer to Figure 1 , the liquid leakage collector includes: a liquid leakage collection tray, a liquid leakage collection funnel;
[0074] The liquid leakage collection tray is located below the liquid leakage converter;
[0075] The liquid leakage collection tray is connected to the liquid leakage collection funnel;
[0076] The liquid leakage collection tray is used to receive the conductive cooling liquid transmitted by the liquid leakage converter:
[0077] The liquid leakage collection tray is also used to collect the conductive cooling liquid and transmit the collected conductive cooling liquid to the liquid leakage collection funnel;
[0078] The liquid leakage collection funnel is used to receive the conductive cooling liquid transmitted by the liquid leakage collection tray and transmit the conductive cooling liquid to the liquid leakage detection module.
[0079] The liquid leakage collection tray is in a flat disk-like structure and is located directly below the liquid leakage converter. The liquid leakage collection tray is used to receive the conductive cooling liquid dripping from the liquid leakage converter and, through the structural design of the liquid leakage collection tray, collect and integrate the scattered conductive cooling liquid.
[0080] The shape of the liquid leakage collection funnel is similar to a common funnel, with a larger upper opening and a smaller lower outlet, and is tightly connected to the liquid leakage collection tray. The liquid leakage collection funnel is used to receive the conductive cooling liquid collected from the tray and, through the contraction structure of the liquid leakage collection funnel, centrally guide the conductive cooling liquid to the location where the liquid leakage detection module is located.
[0081] The liquid leakage collector is carefully installed below the liquid leakage converter, and a suitable and stable distance is maintained between the two to ensure that the conductive cooling liquid can flow smoothly from the converter to the collector. The entire collector is mainly composed of a liquid leakage collection tray and a liquid leakage collection funnel, and the two are tightly connected by bolts, buckles or adhesives, etc., to ensure the sealing performance and structural stability of the connection.
[0082] The liquid leakage collection tray usually adopts a groove design with a certain depth, and the surface is smooth and slightly inclined, so that the conductive cooling liquid can naturally converge towards the center of the tray under the action of gravity. When the conductive cooling liquid drips from the liquid leakage converter onto the liquid leakage collection tray, the structural design of the liquid leakage collection tray can effectively prevent the cooling liquid from splashing and spreading excessively, so that a relatively concentrated liquid flow is formed in the tray. The upper opening of the liquid leakage collection funnel is accurately docked with the liquid outlet of the liquid leakage collection tray. The inner wall of the liquid leakage collection funnel is smooth and gradually shrinking, and this design helps the conductive cooling liquid to slide quickly and smoothly along the funnel wall after flowing into the funnel, and finally flow into the designated position of the liquid leakage detection module from the lower outlet of the liquid leakage collection funnel, thus completing the transmission process of the conductive cooling liquid from the liquid leakage collector to the liquid leakage detection module.
[0083] The special structural design of the liquid leakage collection tray (such as grooves, inclined slopes, etc.) can effectively collect the scattered conductive cooling liquid. Even if there is a certain degree of vibration or inclination during the operation of the liquid-cooled server, it can ensure the stable collection and transmission of the cooling liquid, enhancing the adaptability and stability of the entire liquid leakage detection system.
[0084] In some embodiments, please continue to refer to Figure 1 , the liquid leakage detection module includes: a liquid leakage detector and a liquid leakage detection circuit;
[0085] The liquid leakage detector is located below the liquid leakage transmission module;
[0086] The liquid leakage detector is connected to the liquid leakage detection circuit;
[0087] The liquid leakage detector includes a serrated first liquid leakage detection end and a serrated second liquid leakage detection end; the first liquid leakage detector and the second liquid leakage detector are engaged with each other and not connected;
[0088] The liquid leakage detector is also used to, if the conductive cooling liquid drops onto the liquid leakage detector, then the first liquid leakage detection end and the second liquid leakage detection end are conducted by the conductive cooling liquid;
[0089] The liquid leakage detection circuit is used to generate a liquid leakage detection level;
[0090] The liquid leakage detection circuit is also used to, if the first liquid leakage detection end and the second liquid leakage detection end are conducted, then control the liquid leakage detection level to change and output a liquid leakage alarm message.
[0091] The liquid leakage detector is an element used to detect in real time whether a liquid touches a specified detection area. The liquid leakage detector is used to sense the occurrence of coolant leakage and provide corresponding conductive signal feedback. The liquid leakage detection circuit is a circuit system used to receive the signal of the liquid leakage detector and generate a detection level. The liquid leakage detection circuit processes the detection signal and outputs an alarm message to prompt the user of the state of coolant leakage.
[0092] The serrated first liquid leakage detection end and the serrated second liquid leakage detection end refer to two detection ends with a serrated shape in the liquid leakage detector. This design can increase the contact area with the conductive cooling liquid and improve the sensitivity and accuracy of liquid leakage detection.
[0093] For a better understanding of the liquid leakage detector, as Figure 2 shown, Figure 2 is a schematic structural diagram of a liquid leakage detector provided by an embodiment of the present application. Among them, C is the first liquid leakage detection end, D is the second liquid leakage detection end. When the conductive cooling liquid drops onto the liquid leakage detector, it will cause C and D to be indirectly contacted and conducted.
[0094] When the conductive coolant drips from the liquid leakage transmission module onto the liquid leakage detector, it will cover the surfaces of the first liquid leakage detection terminal and the second liquid leakage detection terminal. Since the coolant is conductive, it will form an electrical path between the two detection terminals, making the two originally insulated parts conduct.
[0095] Since the liquid leakage detection terminals are not directly connected, but an electrical path is established through the conductivity of the coolant, this avoids false alarms caused by environmental interference or other factors, and improves the stability and reliability of the system.
[0096] In some embodiments, please continue to refer to Figure 1 , the liquid leakage detection circuit includes: a first port, a second port, at least two resistors, an operational amplifier, a transistor, and a liquid leakage detector;
[0097] The first port is connected to the first liquid leakage detection terminal, the first port is connected to at least two resistors, and the first port is connected to the operational amplifier;
[0098] The second port is connected to the second liquid leakage detection terminal, and the second port is connected to the operational amplifier;
[0099] The operational amplifier is connected to the transistor, and the transistor is connected to the liquid leakage detector;
[0100] The operational amplifier is configured to, if the first liquid leakage detection terminal and the second liquid leakage detection terminal are not conducting, output a driving voltage and use the driving voltage to conduct the transistor;
[0101] The transistor is configured to, if the transistor is conducting, transmit the driving voltage to the liquid leakage detector;
[0102] The liquid leakage detector is configured to, if it receives the driving voltage, output a first liquid leakage detection level;
[0103] The operational amplifier is further configured to, if the first liquid leakage detection terminal and the second liquid leakage detection terminal are conducting, stop outputting the driving voltage;
[0104] The liquid leakage detector is further configured to, if it does not receive the driving voltage, adjust the first liquid leakage detection level to a second liquid leakage level; the first liquid leakage detection level is lower than the second liquid leakage detection level, and the liquid leakage detection level includes the first liquid leakage detection level and the second liquid leakage detection level;
[0105] The liquid leakage detector is further configured to, if it monitors that the first liquid leakage detection level is adjusted to the second liquid leakage detection level, output a liquid leakage warning message.
[0106] The first port is a connection port in the liquid leakage detection circuit, connected to the first liquid leakage detection terminal of the liquid leakage detector, and at the same time connected to at least two resistors and an operational amplifier, playing a role in transmitting electrical signals and being one of the key nodes for signal transmission in the circuit. The second port is another connection port in the liquid leakage detection circuit, connected to the second liquid leakage detection terminal of the liquid leakage detector and connected to the operational amplifier, working together with the first port to complete the monitoring of the state of the liquid leakage detector and signal transmission. The resistor is a basic electrical component in the liquid leakage detection circuit, used to limit the current magnitude, adjust the voltage distribution, etc. The reasonable configuration of at least two resistors can ensure that the current and voltage in the circuit are within a safe and stable operating range, and at the same time provide appropriate input signals for subsequent components such as operational amplifiers. The operational amplifier is a component in the liquid leakage detection circuit, with characteristics such as high gain and high input impedance. The operational amplifier can amplify and process the input electrical signal, and output a corresponding drive voltage or stop output according to the state of the liquid leakage detector, which is the key component for realizing the liquid leakage detection level control. The transistor is a semiconductor device that plays a switching role in the liquid leakage detection circuit, connected to the operational amplifier and the liquid leakage detector. The on and off states of the transistor are controlled by the drive voltage output by the operational amplifier, thereby determining whether to transmit the drive voltage to the liquid leakage detector, which is an important link for signal transmission and control in the circuit. The liquid leakage detector is the terminal component of the liquid leakage detection circuit. The liquid leakage detector is used to receive the drive voltage transmitted by the transistor and output a corresponding liquid leakage detection level according to whether it receives the voltage, and finally output a liquid leakage alarm message when liquid leakage is detected.
[0107] For better understanding of the liquid leakage detection circuit, as Figure 3 shown, Figure 3 is a schematic diagram of a liquid leakage detection circuit provided by an embodiment of the present application. In Figure 3 , A is the first port, B is the second port, R1, R2, R3, R4 are at least two resistors, VCC is the input power supply, GND is the ground, U1 is the operational amplifier, Q1 is the transistor, and BMC_Pin168 is the liquid leakage detector. Figure 3 A and B in Figure 3 are respectively connected to C and D of the liquid leakage detector. Figure 3A in it is connected to the positive terminal of the operational amplifier, and there is an input voltage at the positive terminal of the operational amplifier due to the action of resistor voltage division. When there is no liquid leakage, it is an open circuit between A and B, that is, there is a voltage difference. At this time, there is a voltage output at the output terminal of the operational amplifier, and the output voltage drives Q1 to conduct. At this time, BMC_Pin168 is at a low level. That is to say, when there is no liquid leakage, BMC_Pin168 is at a low level. In the case of liquid leakage, it is a short circuit between A and B, that is, there is no voltage difference. At this time, there is no voltage output at the output terminal of the operational amplifier, Q1 does not conduct, and at this time, BMC_Pin168 is at a high level. That is to say, when there is liquid leakage, BMC_Pin168 is at a high level. BMC_Pin168 is a printed circuit board (PCB) trace connected to the 168th pin of the Baseboard Manager Controller (BMC) chip.
[0108] For better understanding of the entire process of liquid leakage detection, as Figure 4 shown, Figure 4 is a schematic flowchart of the entire process of a liquid leakage detection provided by an embodiment of the present application. Figure 4 The terminal A in it is the first port. Figure 4 B in it is the second port, and the N-type MOS transistor is a transistor. When there is no liquid leakage in the liquid cooling pipe of the liquid cooling system, the terminal A always remains at a high level. The operational amplifier will output a driving voltage to drive the N-type MOS transistor to conduct, and BMC_Pin168 will continuously remain at a low level. When the liquid cooling pipe leaks, since the terminal A is short-circuited with the terminal B and the terminal B is connected to GND, the terminal A is also changed to a low level. At this time, since the input voltage of the operational amplifier is 0, it will not output a driving voltage to drive the N-type MOS transistor to conduct, and BMC_Pin168 will continuously remain at a high level due to the action of resistor voltage division. The BMC chip on the server motherboard will judge whether there is liquid leakage according to the voltage change of Pin 168. When this BMC_Pin168 is at a high level, there is liquid leakage. When this BMC_Pin168 is at a low level, it means there is no liquid leakage. Once the BMC chip detects the phenomenon of liquid leakage, it immediately lights up the indicator light for alarm warning.
