Due to its high heat dissipation efficiency and low power usage effectiveness (PUE), cold plate liquid cooling has become a leading heat dissipation solution. For example, a single sensor can be used for leak detection. However, due to the high false alarm rate and the sensor's susceptibility to failure when affected by the environment, leak detection accuracy is poor. Summary of the Invention

[0031] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0032] Cold plate liquid cooling technology requires monitoring for leaks. Coolant leaks can cause hardware short circuits, corrosion, and even fires, and the complex connections between the cold plate and the piping further increase the probability of leaks. While a single sensor can be used for detection, this can have a high false alarm rate. For example, humidity sensors are susceptible to interference from condensed water, leading to false alarms. Pressure sensors can be misjudged due to flow fluctuations or pump failures. Leak detection lines require close contact with the leak point, making installation complex and unable to locate even small leaks. Furthermore, a single sensor cannot determine the leak area, increasing the time required to confirm the leak location.

[0033] According to some embodiments, for example, liquid leakage detection can also be performed using conductive detection line technology. However, since the conductive detection line technology uses two parallel conductors 1 and 2, they short-circuit when in contact with liquid, triggering voltage changes 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 misjudgment of resistance fluctuations. Secondly, it can only determine whether there is a leak, but not the location of the leak, which increases the time for manual investigation and makes it impossible to judge the severity of the leak. The laying of complex pipelines will result in detection blind spots.

[0034] The cold plate leakage detection system, method, device and electronic device according to the present disclosure will be described below with reference to the accompanying drawings.

[0035] According to some embodiments, Figure 1 This is an example schematic diagram of a cold plate leakage detection system provided by an embodiment of the present disclosure. Figure 1As shown, a cold plate 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 is used to obtain a data set of the cold plate leakage monitoring area. The control module 102 has a signal input terminal connected to a signal output terminal of the sensor array and is used to process the data set using a data fusion processing algorithm. If the leakage detection results corresponding to the sensors in the sensor array 101 do not meet the result requirements, the control module 102 determines that the leakage detection result corresponding to the cold plate indicates that the cold plate has leakage, and determines the leakage location information of the cold plate based on the installation location information corresponding to the at least two sensors. The sensor types in the sensor array and the number of sensors of a particular sensor type are not limited.

[0036] According to some embodiments, the at least two types of sensors include:

[0037] Multiple humidity sensors are disposed outside the liquid cooling circuit of the cold plate, and the multiple humidity sensors are spaced apart along the liquid flow direction of the liquid cooling circuit, with the distance between adjacent humidity sensors being within a preset distance range;

[0039] According to some embodiments, the at least two types of sensors include:

[0040] A pressure sensor is provided inside the liquid cooling circuit of the cold plate;

[0041] The signal input end of the control module is connected to the signal output end of the pressure sensor, and the control module is used to collect pressure data inside the liquid cooling circuit using the pressure sensor.

[0042] According to some embodiments, the system further comprises:

[0043] A flow sensor is provided inside the liquid cooling circuit of the cold plate;

As shown in Figure 2, the various sensors may include, for example, a humidity sensor, a pressure sensor, a flow sensor, and a temperature sensor. The deployment information of the various sensors may be, for example, as shown in Table 1.

[0050]

[0051] Figure 3 This is a flow chart of a cold plate leakage detection method provided by an embodiment of the present disclosure. Figure 3 As shown, the method comprises the following steps:

[0052] Step 201: Acquire a data set collected by a sensor array for a cold plate leakage monitoring area, wherein the sensor array corresponds to multiple sensor types;

[0053] According to some embodiments, the execution subject of the embodiments of the present disclosure may be, for example, an electronic device. The electronic device may be, for example, a server. The electronic device is not specifically a fixed device. For example, when the device identifier corresponding to the electronic device changes, the electronic device may also change accordingly.

[0054] In some embodiments, the sensor may be, for example, a sensor for collecting data from the cold plate. The sensor array may be, for example, an array consisting of at least one sensor. For example, the number of sensors set for the cold plate leakage monitoring area may be, for example, multiple. The sensor array may correspond to at least two sensor types. Different sensor types may correspond to different sensors, and different sensors may collect different parameters. The number of sensors of the same type that can be set may be at least one. For example, one sensor of the same type may be set. This is not limited in the presently disclosed embodiments.

[0055] According to some embodiments, a cold plate can, for example, efficiently conduct heat generated via a coolant. The cold plate is not specifically a fixed cold plate. For example, if the composition of the cold plate changes, the cold plate can also change accordingly. For example, if the size of the cold plate changes, the cold plate can also change accordingly.

[0056] In some embodiments, the cold plate leakage monitoring area may be, for example, an area capable of detecting whether the cold plate is leaking. The cold plate leakage monitoring area may include, for example, the cold plate itself, or may include non-cold plate areas. The non-cold plate areas may include, for example, liquid cooling pipes.

[0057] In some embodiments, sensor types are used to classify sensors according to different categories, where different sensor types can be used to measure different data. For example, a sensor array can correspond to a cold plate leakage monitoring area, meaning different cold plate leakage monitoring areas can correspond to different sensor arrays. For example, the sensor types and the corresponding quantity of each sensor type in the sensor array can be determined based on requirement information corresponding to the cold plate leakage monitoring area, and the corresponding sensor positions in the sensor array can be determined based on the requirement information.

[0058] In some embodiments, a data set may be, for example, a collection of multiple data points collected by a sensor array. This data set is not a fixed set. For example, if a data point in the data set changes, the data set may also change accordingly. For example, if the sensor array changes, the data set may also change accordingly. For example, if the time point of data collection changes, the data set may also change accordingly.

[0059] In some embodiments, a data set collected by a sensor array for a cold plate leakage monitoring area is obtained, wherein the sensor array corresponds to multiple sensor types.

[0060] Step 202: Processing the data set using a data fusion processing algorithm to determine that, if the leakage detection results corresponding to the sensors in the sensor array have at least two sensors whose leakage detection results do not meet the result requirements, determining that the leakage detection result corresponding to the cold plate indicates that the cold plate has leakage;

[0061] According to some embodiments, a data fusion processing algorithm may be, for example, an algorithm for fusing data collected by a sensor array. The data fusion processing algorithm is not specifically a fixed algorithm. For example, if the data that the data fusion processing algorithm can process changes, the data fusion processing algorithm may also change accordingly. For example, if the algorithm parameters of the data fusion processing algorithm change, the data fusion processing algorithm may also change accordingly.

[0062] In some embodiments, the leakage detection result corresponding to each sensor may be, for example, a detection result obtained by processing the data collected by each sensor. The leakage detection result corresponding to each sensor is not necessarily a fixed result. For example, if the data collection time point changes, the data set may also change accordingly, the data of each sensor may also change accordingly, and the leakage detection result corresponding to each sensor may also change accordingly.

[0063] According to some embodiments, the result requirement may be, for example, a result requirement corresponding to each sensor. The result requirement does not necessarily specify a fixed result. For example, the result requirement may be modified according to a requirement modification instruction. For example, different sensors may correspond to different result requirements. For example, when the ambient temperature changes, the result requirement may be adjusted accordingly, and the result requirement may also change accordingly.

[0064] In some embodiments, the leakage detection result corresponding to the cold plate may be, for example, the result of performing a leakage detection on the cold plate leakage monitoring area to determine whether the cold plate is leaking. The leakage detection result corresponding to the cold plate does not specifically refer to a fixed result. For example, when the leakage detection results corresponding to each sensor change, the leakage detection result corresponding to the cold plate may also change accordingly. For example, the leakage detection result corresponding to the cold plate may include information indicating that the cold plate is not leaking and that the cold plate is leaking, and may also include the leakage level corresponding to when the cold plate is leaking. The present disclosed embodiments are not limited to this.

[0065] In some embodiments, a data fusion processing algorithm is used to process the data set to obtain leakage detection results corresponding to each sensor in the sensor array. If it is determined that the leakage detection results corresponding to the sensors in the sensor array do not meet the result requirements for at least two sensors, the leakage detection result corresponding to the cold plate is determined to indicate that the cold plate has leakage.

[0066] According to some embodiments, the at least two sensors whose leakage detection results do not meet the result requirement in the embodiments of the present disclosure may include at least two sensors of different sensor types, or at least two sensors of the same sensor type. When the at least two sensors are three sensors, they may include two sensors of the same sensor type and one sensor of a different sensor type, which is not limited in the embodiments of the present disclosure.

[0067] Step 203: Determine the leakage position information of the cold plate according to the installation position information corresponding to the at least two sensors.

[0068] In some embodiments, the location information may include, for example, the location of the sensor on a device associated with the cold plate. This location information may be on or off the cold plate, and may be any location where data from the cold plate can be collected. This location information does not necessarily specify a fixed location. For example, if the sensor changes, the location information may also change accordingly.

[0069] According to some embodiments, the cold plate leakage location information is used to indicate the location of the cold plate leakage. The cold plate leakage location information does not specifically refer to a fixed location. For example, when at least two sensors change, the cold plate leakage location information may also change accordingly.

[0070] In some embodiments, the leakage position information of the cold plate may be determined based on the installation position information corresponding to at least two sensors.

[0071] According to the present disclosure, a data set collected by a sensor array for a cold plate leakage monitoring area is obtained, wherein the sensor array corresponds to multiple sensor types; a data fusion processing algorithm is used to process the data set, and if the leakage detection results corresponding to the sensors in the sensor array do not meet the result requirements, the leakage detection result corresponding to the cold plate is determined to indicate that the cold plate has a leakage; and the leakage location information of the cold plate is determined based on the installation position information corresponding to the at least two sensors. Therefore, the cold plate leakage can be jointly detected using the data set collected by the sensor array and the data fusion processing algorithm. This can reduce the high false alarm rate of a single sensor and the situation where a single sensor is easily affected by the environment, resulting in poor leakage detection accuracy. The accuracy of cold plate leakage detection can be improved, the leakage location can be determined based on 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 overcome. This can improve the accuracy of cold plate leakage detection, improve the robustness and stability of leakage detection in the liquid cooling system, and ensure the safe and stable operation of the liquid cooling system. In addition, it can reduce the false alarms caused by conductor short circuits due to environmental changes in conductive detection line technology, 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 expand the application scope of cold plate leakage detection.

[0072] 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.

[0073] Furthermore, in a possible implementation of this embodiment, Figure 4This 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:

[0074] Step 301: Acquire a data set collected by a sensor array for a cold plate leakage monitoring area, wherein the sensor array corresponds to multiple sensor types;

[0075] Among them, the relevant descriptions have been mentioned above and will not be repeated here.

[0076] According to some embodiments, the main control chip of the electronic device may have, for example, relatively high computing performance, and may have, for example, multiple interfaces, such as an Inter-Integrated Circuit (I²C), a Serial Peripheral Interface (SPI), a Universal Asynchronous Receiver / Transmitter (UART), and the like. Multiple interfaces can be easily connected to various sensors such as humidity, pressure, and flow to realize data collection. At the same time, it also supports network interfaces (such as Ethernet), and can upload processed data to the cloud or other management systems for remote monitoring and management. For example, leakage detection data can be transmitted to a server in a data center in real time through an Ethernet interface, and operation and maintenance personnel can remotely view the status of the equipment. According to some embodiments, Figure 5 This is a flow chart of another cold plate leakage detection method provided by the embodiment of the present disclosure. Figure 5 As shown, for example, it may include collecting data through a sensor array, and performing sliding average filtering and threshold filtering.

[0077] According to some embodiments, before processing the data set using a data fusion processing algorithm to determine the liquid leakage detection result corresponding to each sensor in the sensor array, the method further includes:

[0078] The data set is subjected to sliding filtering and / or threshold filtering to obtain a processed data set. Thus, the data can be unified and denoised, reducing the likelihood of inaccurate leak detection due to direct leak detection based on the data, reducing the probability of false alarms, and improving the accuracy of leak detection.

[0079] In some embodiments, the sliding filter process may be, for example, a sliding average filter process. Specifically, for example, the data collected by each sensor may be averaged by obtaining a preset number of times of data closest to the current time. The preset number of times may be, for example, 5 times. It may also be related to the operating time of the system.

[0080] In some embodiments, threshold filtering can include adding a calibration process to each sensor. Data within a certain threshold range can be retained. Specifically, data can be validated only when the temperature is greater than 20°C and the humidity is greater than 90%. This eliminates the effects of condensation and improves leak detection accuracy.

[0081] Step 302: Acquire environmental information corresponding to the cold plate leakage monitoring area once every first preset time period, wherein the environmental information includes at least one of an ambient temperature acquired by a temperature sensor and server load information acquired by a baseboard management controller (BMC);

[0082] According to some embodiments, the first preset duration can be used, for example, to indicate the duration of the interval between acquisition of environmental information. The first in the first preset duration is used to distinguish it from the remaining durations. The first preset duration does not specifically refer to a fixed duration. For example, when the specific value corresponding to the first preset duration changes, the first preset duration may also change accordingly. For example, when a modification instruction for the first preset duration is received, the first preset duration may also change accordingly.

[0083] In some embodiments, the environmental information may be used to indicate the current environment of the cold plate. This environmental information may include, for example, the ambient temperature acquired by a temperature sensor and server load information acquired by a BMC. This environmental information is not specific to a fixed set of information. For example, if the time point at which the environmental information is collected changes, the environmental information may also change accordingly. For example, if the specific information included in the environmental information changes, the environmental information may also change accordingly.

[0084] In some embodiments, for example, the environmental information of the cold plate may be obtained once every first preset time period. Figure 4 As shown, for example, when the sensor is not triggered, that is, when the cold plate is not leaking, the monitoring is maintained and the threshold is dynamically adjusted.

[0085] Step 303: Adjust the result requirements corresponding to each sensor according to the environmental information and obtain the adjusted result requirements;

[0086] Among them, the relevant descriptions have been mentioned above and will not be repeated here.

[0087] In some embodiments, the result requirements corresponding to each sensor are adjusted based on the environmental information to obtain the adjusted result requirements. Different environmental information may correspond to different adjustment measures. Specific examples may be shown in Table 2.

[0088] Table 2

[0089]

[0090] The numerical values ​​in the embodiments of the present disclosure are for illustration only and do not refer to any specific fixed numerical values.

[0091] Specifically, for example, it may include obtaining environmental information, where the environmental information includes the ambient temperature obtained through a temperature sensor and the server load information obtained through a baseboard management controller BMC. When the server load information and the ambient temperature do not meet the information requirements, an adjustment strategy corresponding to the environmental information that does not meet the information requirements may be obtained, and the adjustment strategy may be used to adjust the result requirements corresponding to the corresponding sensor.

[0092] For example, when the ambient temperature is greater than 30°C, the obtained adjustment strategy may be to reduce the humidity alarm threshold from 90% relative humidity (90% RH) to 85% relative humidity (85% RH) and the pressure alarm threshold from 0.4 MPa to 0.35 MPa, and the humidity alarm threshold and the pressure alarm threshold are adjusted using this adjustment strategy.

[0093] Step 304: Process the data set using a data fusion processing algorithm to determine that, if the leakage detection results corresponding to the sensors in the sensor array have at least two sensors whose leakage detection results do not meet the adjusted result requirements, then determine that the leakage detection result corresponding to the cold plate indicates that the cold plate has leakage.

[0094] Among them, the relevant descriptions have been mentioned above and will not be repeated here.

[0095] According to some embodiments, a data fusion processing algorithm is used to process a data set, and when it is determined that the leakage detection results corresponding to the sensors in the sensor array have leakage detection results of at least two sensors that do not meet result requirements, determining that the leakage detection result corresponding to the cold plate indicates that the cold plate has leakage includes:

[0096] Obtaining the leakage detection threshold corresponding to each sensor in the sensor array;

[0097] Comparing the data corresponding to each sensor in the data set with the leakage detection threshold, and obtaining the data comparison results corresponding to each sensor in the sensor array;

[0098] Determine the leakage detection result of each sensor based on the data comparison results and duration;

[0099] If the leakage detection results of at least two sensors do not meet the result requirements and the failure lasts for a second predetermined period, the leakage detection result corresponding to the cold plate is determined to indicate a cold plate leak. Therefore, by comparing the sensor array data, inaccurate leakage detection caused by a single threshold can be reduced, thereby improving the accuracy of cold plate leakage detection.

[0100] In some embodiments, sensors may include, for example, a humidity sensor, a pressure sensor, and a flow sensor. The humidity sensor may require a humidity greater than 90% relative humidity (RH), the pressure sensor may require a pressure less than 80% of a rated value (e.g., 0.4 MPa), and the flow sensor may require a flow less than 85% of a rated value (e.g., 4.25 liters / minute).

[0101] Determining that the leakage detection result corresponding to the cold plate indicates that there is leakage in the cold plate may include, for example: the humidity sensor leakage detection result and the pressure sensor leakage detection result do not meet the result requirements and last for two seconds; the humidity sensor leakage detection result and the flow sensor leakage detection result do not meet the result requirements and last for two seconds; the pressure sensor leakage detection result and the flow sensor leakage detection result do not meet the result requirements and last for two seconds.

[0102] The weights corresponding to the various sensors may be the same or different. Examples of sensors may be shown in Table 3.

[0103] Table 3

[0104]

[0105] According to some embodiments, for example, when two sensors trigger an alarm and the alarm lasts for a preset time, it can be determined that the cold plate is in a leaking state, wherein the existence of the preset time can, for example, prevent jitter and improve detection accuracy.

[0106] For example, when the humidity is 95% RH (trigger) and the pressure is 0.35 MPa (trigger), it can be determined that the cold plate is leaking.

[0107] For example, if the flow rate meets the result requirements (such as 5L / min), even if the leakage detection results corresponding to the humidity and the leakage detection results corresponding to the pressure do not meet the result requirements, it is determined to be "condensation interference" rather than leakage of the cold plate.

[0108] According to some embodiments, if the leakage detection results corresponding to the sensors include at least two sensors whose leakage detection results do not meet the result requirement and the duration reaches a second preset duration, after determining that the leakage detection result corresponding to the cold plate indicates that the cold plate has leakage, the method further includes:

[0109] Obtaining a leakage level based on a difference between data collected by at least two sensors and a leakage detection threshold corresponding to each sensor;

[0110] Obtaining a leakage response measure corresponding to the leakage level from a set of leakage response measures corresponding to at least two sensors;

[0111] Execute the actions corresponding to the leak response measures. This improves the compatibility of the leak response set with sensors that don't meet the result requirements. When the sensor array determines that the cold plate is leaking, the accuracy of the leak response measures is improved, which can reduce response time, improve response efficiency, and enhance the accuracy of leak control. Furthermore, leak response measures can be directly determined without manual investigation, reducing leak response time and improving the efficiency of leak response implementation.

[0112] The leakage response measures set may include, for example, emergency shutdown, load adjustment, and information upload, and may specifically include:

[0113] Emergency shutdown: Low level to the cooling distribution unit (CDU) cooling manager, closing the solenoid valve to cut off the coolant;

[0114] Send a command to the BMC via UART to limit the load of the corresponding server's Central Processing Unit (CPU) to 50% (to prevent overheating);

[0115] Upload BMC network management interface WEB to notify operation and maintenance alarm information.

[0116] According to some embodiments, obtaining a leakage response measure corresponding to a leakage level from a set of leakage response measures corresponding to at least two sensors includes:

[0117] Obtaining a corresponding leakage level of the cold plate according to leakage detection results of at least two sensors;

[0118] The leakage response measure corresponding to the leakage level is obtained from the leakage response measure set corresponding to at least two sensors. Therefore, different leakage levels can correspond to different leakage response measures, which can improve the accuracy of determining the leakage response measure and improve the accuracy of cold plate leakage control.

[0119] Step 305: determining the leakage position information of the cold plate according to the setting position information corresponding to the at least two sensors;

[0120] Among them, the relevant descriptions have been mentioned above and will not be repeated here.

[0121] Step 306 : When the leakage detection result of one sensor among the leakage detection results corresponding to the sensors does not meet the result requirement, a warning message corresponding to the cold plate is issued.

[0122] Among them, the relevant descriptions have been mentioned above and will not be repeated here.
