[0013] The drawings are used to better understand the solution and do not constitute a limitation to the present disclosure. Among them: Figure 1 is an exemplary schematic diagram of a cold plate leakage detection system provided by an embodiment of the present disclosure; Figure 2 is an exemplary schematic diagram of a sensor arrangement provided by an embodiment of the present disclosure; Figure 3 is a schematic flowchart of a cold plate leakage detection method provided by an embodiment of the present disclosure; Figure 4 is a schematic flowchart of another cold plate leakage detection method provided by an embodiment of the present disclosure; Figure 5 is an exemplary schematic diagram of yet another cold plate leakage detection method provided by an embodiment of the present disclosure; Figure 6 is a schematic structural diagram of a cold plate leakage detection device provided by an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings. Various details of the embodiments of the present disclosure are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

[0015] In cold plate liquid cooling technology, it is necessary to monitor whether the cold plate leaks liquid. Among them, coolant leakage may cause hardware short circuits, corrosion, or even fires, and the complex connection between the cold plate and the pipeline may further increase the leakage probability. For example, a single sensor can be used for detection, but the false alarm rate of a single sensor is relatively high. For example, a humidity sensor is easily interfered by condensed water and generates false alarms; a pressure sensor: flow fluctuations or pump failures may lead to misjudgment; a liquid leakage detection line: it needs to be in close contact with the liquid leakage point, and the installation is complex and it is impossible to locate small leaks. Moreover, single-sensor detection cannot determine the leakage area, increasing the time required to confirm the liquid leakage location.

[0016] According to some embodiments, for example, liquid leakage detection can also be performed through the conductive detection line technology. However, since the conductive detection line technology uses two parallel conductors 1 and 2, which are short-circuited when in contact with the liquid, triggering a voltage change to achieve detection. However, due to environmental changes, when condensed water appears on the surface of the detection line, false alarms will occur, and in a high-frequency electromagnetic environment, the detection line may generate stray currents due to electromagnetic induction, resulting in resistance fluctuations and misjudgment. Secondly, it can only determine whether there is liquid leakage, but cannot determine the liquid leakage location, increasing the time for manual troubleshooting, and the severity of the liquid leakage cannot be judged. Detection blind spots will appear in the laying of complex pipelines.

[0017] The cold plate liquid leakage detection system, method, device, and electronic device according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0018] According to some embodiments, Figure 1 is an example schematic diagram of a cold plate liquid leakage detection system provided by the embodiments of the present disclosure. As Figure 1As shown, the cold plate liquid leakage detection system 100 includes a sensor array 101 and a control module 102. The sensor array 101 includes at least two types of sensors, and the sensor array is used to obtain a data set of the cold plate liquid leakage monitoring area; the control module 102, the signal input end of the control module 102 is connected to the signal output end of the sensor array, and the control module 102 is used to process the data set by using a data fusion processing algorithm, and determine that when the liquid leakage detection results corresponding to the sensors in the sensor array 101 do not meet the result requirements for at least two sensors, determine that the liquid leakage detection result corresponding to the cold plate is that the cold plate has liquid leakage, and, according to the setting position information corresponding to at least two sensors, determine the liquid leakage position information of the cold plate. Among them, there are no restrictions on the types of sensors in the sensor array and the number of sensors of a certain type of sensor.

As shown in Figure 2, among them, multiple sensors can include, for example, a humidity sensor, a pressure sensor, a flow sensor, and a temperature sensor. Among them, the deployment information of multiple sensors can be shown in Table 1, for example.

[0024] Table 1

[0025] Figure 3 A schematic flowchart of a cold plate liquid leakage detection method provided by an embodiment of the present disclosure. As Figure 3 shown, the method includes the following steps: Step 201, obtain a data set collected by a sensor array for a cold plate liquid leakage monitoring area, where the sensor types corresponding to the sensor array are multiple; According to some embodiments, the execution subject of the embodiments of the present disclosure can be, for example, an electronic device. The electronic device can be, for example, a server. The electronic device does not specifically refer to a certain fixed device. For example, when the device identifier corresponding to the electronic device changes, the electronic device can also change accordingly.

[0026] In some embodiments, the sensor can be, for example, a sensor that collects data on the cold plate. The sensor array can be, for example, an array composed of at least one sensor. For example, the number of sensors set for the cold plate liquid leakage monitoring area can be multiple. Among them, the sensor array can correspond to at least two sensor types. Different sensor types can correspond to different sensors, and different sensors can collect different parameters. Among them, the number of sensors of the same type that can be set can be at least one. For example, one sensor of one type can be set, for example. The embodiments of the present disclosure do not limit this.

[0027] According to some embodiments, the cold plate can, for example, efficiently conduct the generated heat through a coolant. Among them, the cold plate does not specifically refer to a certain fixed cold plate. For example, when the composition of the cold plate changes, the cold plate can also change accordingly. For example, when the size of the cold plate changes, the cold plate can also change accordingly.

[0028] In some embodiments, the cold plate liquid leakage monitoring area can be, for example, an area where it is possible to determine whether the cold plate leaks. The cold plate liquid leakage monitoring area can include, for example, the cold plate itself, and can also include a non-cold plate area. The non-cold plate area can include, for example, a liquid cooling pipe.

[0029] In some embodiments, the sensor type is a type obtained by classifying sensors according to different classifications. Among them, different sensor types can be used to measure different data. Among them, the sensor array can correspond to the cold plate liquid leakage monitoring area, that is, different cold plate liquid leakage monitoring areas can correspond to different sensor arrays. For example, the sensor type of the sensor array and the quantity corresponding to each sensor type can be determined according to the demand information corresponding to the cold plate liquid leakage monitoring area, and the sensor positions corresponding to the sensor array can be determined according to the demand information.

[0030] In some embodiments, the data set can be, for example, a collective formed by aggregating multiple data collected by the sensor array. This data set does not specifically refer to a certain fixed set. For example, when a certain data in the data set changes, the data set can also change accordingly. For example, when the sensor array changes, the data set can also change accordingly. For example, when the data acquisition time point changes, the data set can also change accordingly.

[0031] In some embodiments, the data set collected by the sensor array for the cold plate liquid leakage monitoring area is obtained, where the sensor types corresponding to the sensor array are multiple.

[0032] Step 202: Use a data fusion processing algorithm to process the data set. When it is determined that the liquid leakage detection results corresponding to at least two sensors among the sensors in the sensor array do not meet the result requirements, determine that the liquid leakage detection result corresponding to the cold plate is that the cold plate has liquid leakage; According to some embodiments, the data fusion processing algorithm can be, for example, an algorithm for fusing the data collected by the sensor array. This data fusion processing algorithm does not specifically refer to a certain fixed algorithm. For example, when the data that the data fusion processing algorithm can process changes, the data fusion processing algorithm can also change accordingly. For example, when the algorithm parameters of the data fusion processing algorithm change, the data fusion processing algorithm can also change accordingly.

[0033] In some embodiments, the liquid leakage detection results corresponding to each sensor can be, for example, the detection results obtained by processing the data collected by each sensor. Among them, the liquid leakage detection results corresponding to each sensor do not specifically refer to a certain fixed result. For example, when the data acquisition time point changes, the data set can also change accordingly, the data of each sensor can also change accordingly, and the liquid leakage detection results corresponding to each sensor can also change accordingly.

[0034] According to some embodiments, the result requirements can be, for example, result requirements corresponding to each sensor. The result requirements do not specifically refer to a certain fixed result. For example, the result requirements can be modified according to the requirements by modifying the instructions. For example, different sensors can correspond to different result requirements. For example, when the ambient temperature changes, the result requirements can be adjusted accordingly, and the result requirements can also change accordingly.

[0035] Among some embodiments, the liquid leakage detection result corresponding to the cold plate can be, for example, the result of detecting liquid leakage in the liquid leakage monitoring area corresponding to the cold plate to determine whether the cold plate leaks. The liquid leakage detection result corresponding to the cold plate does not specifically refer to a certain fixed result. For example, when the liquid leakage detection results corresponding to each sensor change, the liquid leakage detection result corresponding to the cold plate can also change accordingly. For example, the liquid leakage detection result corresponding to the cold plate can include information indicating that the cold plate does not leak and that the cold plate leaks. Among them, it can also include the liquid leakage level corresponding to when the cold plate leaks. The embodiments of the present disclosure do not limit this.

[0036] Among some embodiments, by using a data fusion processing algorithm to process the data set, the liquid leakage detection results corresponding to each sensor in the sensor array can be obtained. In the case where it is determined that the liquid leakage detection results corresponding to at least two sensors in the sensor array do not meet the result requirements, it is determined that the liquid leakage detection result corresponding to the cold plate is that the cold plate has a liquid leakage.

[0037] According to some embodiments, at least two sensors among the embodiments of the present disclosure whose liquid leakage detection results do not meet the result requirements can be at least two sensors of different sensor types, or can also include at least two sensors of the same sensor type. When the at least two sensors are three sensors, it can be two sensors of the same sensor type and one sensor of a different sensor type. The embodiments of the present disclosure do not limit this.

[0038] Step 203, determine the liquid leakage position information of the cold plate according to the setting position information corresponding to at least two sensors.

[0039] Among some embodiments, the setting position information can be, for example, the setting position of the sensor in the cold plate-related device. This position information can be on the cold plate or not on the cold plate, and any position where the data of the cold plate can be collected is acceptable. The setting position information does not specifically refer to a certain fixed position information. For example, when the sensor changes, the setting position information can also change accordingly.

[0040] According to some embodiments, the liquid leakage position information of the cold plate is used to indicate the position where the cold plate leaks. The liquid leakage position information of the cold plate does not specifically refer to a certain fixed position. For example, when at least two sensors change, the liquid leakage position information of the cold plate can also change accordingly.

[0041] In some embodiments, the leakage position information of the cold plate may be determined based on the setting position information corresponding to at least two sensors.

[0042] According to the present invention, a data set collected by a sensor array for a cold plate leakage monitoring area is obtained, wherein the sensor array corresponds to a plurality of sensor types; a data fusion processing algorithm is used to process the data set, and when the leakage detection results corresponding to each sensor in the sensor array have at least two leakage detection results that do not meet the result requirements, the leakage detection result corresponding to the cold plate is determined to be that the cold plate has leakage; and the leakage position information of the cold plate is determined according to the setting position information corresponding to at least two sensors. Therefore, the data set collected by the sensor array can be combined with the data fusion processing algorithm to jointly detect whether the cold plate is leaking, which can reduce the high false alarm rate of a single sensor, and can reduce the situation where a single sensor is easily invalidated due to the influence of the environment, so that the accuracy of leakage detection is poor, and the accuracy of cold plate leakage detection can be improved. The leakage position can be determined by the position of each sensor in the sensor array, and the limitation of the detection area of the leakage detection line by a single sensor can be reduced, and the accuracy of cold plate leakage detection can be improved, and the robustness and stability reliability of liquid cooling system leakage detection can be improved to ensure the safe and stable operation of the liquid cooling system. In addition, it can reduce the false alarms caused by conductor short circuits in conductive detection line technology due to environmental changes, reduce the false judgments of resistance fluctuations caused by stray currents generated by electromagnetic induction in the detection line in a high-frequency electromagnetic environment, and increase the application scope of cold plate leakage detection.

[0043] It should be noted that the embodiments of the present disclosure may include multiple steps. For the convenience of description, these steps are numbered, but these numbers do not limit the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of the present disclosure do not limit this.

[0044] Furthermore, in a possible implementation of this embodiment, Figure 4 This is a flow chart of another cold plate leakage detection method provided by the embodiment of the present disclosure. Figure 4 As shown, the method comprises the following steps: Step 301, obtaining a data set collected by a sensor array for a cold plate leakage monitoring area, wherein the sensor array corresponds to multiple sensor types; Among them, the relevant descriptions have been mentioned above and will not be repeated here.

[0045] According to some embodiments, the main control chip of the electronic device can, for example, have relatively high computing performance and can, for example, be equipped with multiple interfaces. The multiple interfaces can include, for example, Inter-Integrated Circuit (I²C), Serial Peripheral Interface (SPI), Universal Asynchronous Receiver / Transmitter (UART), etc. The multiple interfaces can, for example, facilitate connection with various sensors such as humidity, pressure, and flow rate sensors to achieve data acquisition. At the same time, it also supports network interfaces (such as Ethernet) and can upload the processed data to the cloud or other management systems for remote monitoring and management. For example, through the Ethernet interface, the liquid leakage detection data can be transmitted to the server in the data center in real time, and the operation and maintenance personnel can remotely view the device status. According to some embodiments, Figure 5 is a schematic flowchart of another method for detecting liquid leakage in a cold plate provided by an embodiment of the present disclosure. As Figure 5 shown, it can, for example, include data acquisition through a sensor array and performing moving average filtering processing and threshold filtering processing.

[0046] According to some embodiments, before using a data fusion processing algorithm to process a data set and determine the liquid leakage detection results corresponding to each sensor in the sensor array, it further includes: Performing moving filtering processing and / or threshold filtering processing on the data set to obtain a processed data set. Therefore, the data can be unified and denoised, reducing the situation where liquid leakage detection is inaccurate when directly detecting liquid leakage based on the data and reducing the probability of false alarms, and improving the accuracy of liquid leakage detection.

[0047] In some embodiments, the moving filtering processing can, for example, be moving average filtering processing. Specifically, for the data collected by each sensor, the data of a preset number of times closest to the current time can be obtained, and the average value of this data can be calculated. The preset number of times can, for example, be 5 times. It can also be related to the running duration of the system, for example.

[0048] In some embodiments, the threshold filtering processing can, for example, add a verification process for each sensor. The data within a certain threshold range can be selected for retention. Specifically, for example, when the temperature is greater than 20°C and the humidity is greater than 90%, the data is valid, which can exclude the influence of condensed water and improve the accuracy of liquid leakage detection.

[0049] Step 302: Obtain the environmental information corresponding to the cold plate liquid leakage monitoring area every first preset time period. The environmental information includes at least one of the environmental temperature obtained by a temperature sensor and the server load information obtained by a Baseboard Management Controller (BMC). According to some embodiments, the first preset time period can be used, for example, to indicate the interval time for obtaining environmental information. The "first" in the first preset time period is used to distinguish it from other time periods. The first preset time period does not specifically refer to a certain fixed time period. For example, when the specific value corresponding to the first preset time period changes, the first preset time period can also change accordingly. For example, when a modification instruction for the first preset time period is received, the first preset time period can also change accordingly.

[0050] In some embodiments, the environmental information can be used, for example, to indicate the information of the environment where the cold plate is currently located. The environmental information can include, for example, the environmental temperature obtained by a temperature sensor and the server load information obtained by a BMC. The environmental information does not specifically refer to a certain fixed information. For example, when the collection time point of the environmental information changes, the environmental information can also change accordingly. For example, when the specific information included in the environmental information changes, the environmental information can also change accordingly.

[0051] In some embodiments, for example, the environmental information of the cold plate can be obtained every first preset time period. As Figure 4 shown, for example, when the sensor is not triggered, that is, when the cold plate does not leak liquid, monitoring is maintained and the threshold is dynamically adjusted.

[0052] Step 303: Adjust the result requirements corresponding to each sensor according to the environmental information, and obtain the adjusted result requirements; Among them, the related descriptions are as above and will not be repeated here.

[0053] In some embodiments, the result requirements corresponding to each sensor are adjusted according to the environmental information, and the adjusted result requirements are obtained. Among them, different environmental information can correspond to different adjustment measures. Specifically, for example, it can be as shown in Table 2.

[0054] Table 2

[0055] Among them, the numerical values in the embodiments of the present disclosure are all for illustrative purposes and do not specifically refer to a certain fixed numerical value.

[0056] Specifically, for example, it may include obtaining environmental information, where the environmental information includes the environmental temperature obtained through a temperature sensor and the server load information obtained through a baseboard management controller (BMC). When there is environmental information that does not meet the information requirements among the server load information and the environmental temperature, an adjustment strategy corresponding to the environmental information that does not meet the information requirements can be obtained, and this adjustment strategy can be used to adjust the result requirements corresponding to the respective sensors.

[0057] For example, when the environmental temperature is greater than 30°C, the obtained adjustment strategy may be to lower the humidity alarm threshold from 90% relative humidity (90% RH) to 85% relative humidity (85% RH) and lower the pressure alarm threshold from 0.4 MPa to 0.35 MPa, and this adjustment strategy is used to adjust the humidity alarm threshold and the pressure alarm threshold.

[0058] Step 304: Process the data set using a data fusion processing algorithm. When there are at least two sensors among the leakage detection results corresponding to the respective sensors in the sensor array that do not meet the adjusted result requirements, determine that the leakage detection result corresponding to the cold plate is that there is leakage in the cold plate. Among them, the relevant description is as described above and will not be elaborated here.

[0059] According to some embodiments, when processing the data set using a data fusion processing algorithm and determining that there are at least two sensors among the leakage detection results corresponding to the respective sensors in the sensor array that do not meet the result requirements, determining that the leakage detection result corresponding to the cold plate is that there is leakage in the cold plate includes: Obtain the leakage detection threshold corresponding to each sensor in the sensor array; Perform a comparison process on the data corresponding to each sensor in the data set with the leakage detection threshold to obtain the data comparison results corresponding to each sensor in the sensor array; Determine the leakage detection results of each sensor according to the data comparison results and the duration; When there are at least two sensors among the leakage detection results corresponding to the respective sensors that do not meet the result requirements and the duration reaches the second preset duration, determine that the leakage detection result corresponding to the cold plate is that there is leakage in the cold plate. Therefore, through the comparison of the sensor array data, the situation where the leakage detection is inaccurate due to a single threshold can be reduced, and the accuracy of the cold plate leakage detection can be improved.

[0060] In some embodiments, sensors may include, for example, humidity sensors, pressure sensors, and flow sensors. Among them, the result requirements corresponding to the humidity sensor may be, for example, a humidity greater than 90% relative humidity (90% RH), the result requirements corresponding to the pressure sensor may be, for example, a pressure value less than 80% of the rated value (the rated value of 80% may be 0.4 megapascals MPa), and the result requirements corresponding to the flow sensor may be, for example, a flow value less than 85% of the rated value (the rated value of 85% may be 4.25 liters L / minute min).

[0061] Determining that the cold plate has a liquid leakage detection result indicating liquid leakage in the cold plate may include, for example: the liquid leakage detection results of the humidity sensor and the pressure sensor do not meet the result requirements and last for two seconds; the liquid leakage detection results of the humidity sensor and the flow sensor do not meet the result requirements and last for two seconds; the liquid leakage detection results of the pressure sensor and the flow sensor do not meet the result requirements and last for two seconds.

[0062] Among them, the weights corresponding to each sensor may be the same or different. Examples of sensors may be as shown in Table 3.

[0063] Table 3

[0064] According to some embodiments, for example, when two sensors trigger an alarm and last for a preset duration, it can be determined that the cold plate is in a liquid leakage state, where the existence of the preset duration can prevent jitter and improve the accuracy of detection.

[0065] For example, when the humidity is 95% RH (triggered) and the pressure is 0.35 MPa (triggered), it can be determined that the cold plate is in a liquid leakage state.

[0066] Among them, for example, if the flow meets the result requirements (such as 5 L / min), even if the liquid leakage detection results corresponding to the humidity and the pressure do not meet the result requirements, it is determined as "condensation interference" rather than the cold plate having liquid leakage.

[0067] According to some embodiments, in the case where at least two of the liquid leakage detection results corresponding to each sensor do not meet the result requirements and the duration reaches the second preset duration, after determining that the liquid leakage detection result corresponding to the cold plate indicates liquid leakage in the cold plate, it further includes: Obtaining a liquid leakage level based on the difference between the data collected by at least two sensors and the liquid leakage detection thresholds corresponding to each sensor; Obtaining the leakage response measure corresponding to the liquid leakage level in the set of leakage response measures corresponding to at least two sensors; Perform operations corresponding to the leakage response measures. Therefore, the matching between the set of leakage response measures and the sensors that do not meet the result requirements can be improved. When it is determined by the sensor array that the cold plate is leaking liquid, the accuracy of obtaining the leakage response measures can be improved, the response time can be reduced, the response efficiency can be improved, and the accuracy of leakage control can be improved. In addition, the leakage response measures that can be directly determined do not require manual troubleshooting, which can reduce the leakage response time and improve the efficiency of implementing the leakage response measures.

[0068] Among them, the set of leakage response measures specifically includes, for example: emergency shutdown, load adjustment, and information upload. Specifically, it can be: Emergency shutdown: Send a low level to the cooling manager of the Cooling Distribution Units (CDU) to close the solenoid valve to cut off the coolant; Send an instruction to the BMC through UART to limit the load of the corresponding server Central Processing Unit (CPU) to 50% (to avoid overheating); Upload the WEB notification of the BMC network management interface to the operation and maintenance for alarm information.

[0069] According to some embodiments, in the set of leakage response measures corresponding to at least two sensors, obtaining the leakage response measures corresponding to the leakage level includes: Obtain the leakage level corresponding to the cold plate according to the leakage detection results of at least two sensors; In the set of leakage response measures corresponding to at least two sensors, obtain the leakage response measures corresponding to the leakage level. Therefore, different leakage levels can correspond to different leakage response measures, which can improve the accuracy of determining the leakage response measures and the accuracy of cold plate leakage control.
