[0036] The specific embodiments of the present application have been shown in the above figures, and will be described in more detail hereinafter. These figures and the written description are not intended to limit the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. Unless otherwise indicated, the same numbers on different drawings represent the same or similar elements. The following detailed description does not limit the present application concept in any way. Instead, they merely illustrate devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] Figure 1 A flow diagram of the liquid leakage detection process implemented by the existing liquid cooling leakage detection system provided by the present application is shown in the following figure. Figure 1 As shown in the figure, the current liquid cooling leakage detection system uses the liquid cooling control system to transfer the cooling liquid from the liquid cooling pipe to the heat dissipation module inside the liquid cooling server, and at the same time, connects a detection line to the heat dissipation module, and connects the other end of the detection line to a detection chip, so as to realize the leakage detection of the liquid cooling server.

[0039] When a liquid leakage anomaly occurs, if the liquid leakage source is located in the liquid cooling components of other non-server parts inside the liquid cooling cabinet, the first to detect the anomaly will be these external components, rather than the liquid cooling server itself. In this case, the current liquid cooling leakage detection system will have a missed detection, thereby reducing the troubleshooting efficiency of the liquid leakage fault.

[0040] To solve the above problems, the present application provides a liquid cooling leakage detection system, which sets a cabinet bottom detection sensor array at the bottom of the liquid cooling cabinet to monitor the liquid accumulation state inside the liquid cooling cabinet in real time and generate a liquid accumulation signal; sets a cold plate detection unit at the cold plate inside the liquid cooling server to monitor the cooling liquid leakage state of the cold plate in real time and generate a leakage signal of the cold plate; uses the liquid cooling control system to receive and respond to the liquid accumulation signal and the leakage signal of the cold plate, generate a control instruction for triggering corresponding control processing, and realize the liquid leakage detection of the liquid cooling cabinet and the liquid cooling server at the same time, thereby improving the accuracy of the liquid leakage detection and reducing the probability of missed detection.

[0041] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described again in some examples. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0042] Figure 2 Structure diagram of the liquid cooling liquid leakage detection system provided by the embodiments of the present application Figure 1 As shown in the figure, the liquid cooling liquid leakage detection system comprises: a cabinet liquid leakage detection system 201, a server liquid leakage detection system 202 and a liquid cooling control system 203. Figure 2

[0043] The cabinet liquid leakage detection system 201 comprises: a cabinet bottom plate detection sensor array arranged at the bottom of the liquid cooling cabinet, for monitoring the liquid accumulation state inside the liquid cooling cabinet in real time, and generating a liquid accumulation signal.

[0044] The server liquid leakage detection system 202 comprises: a cold plate detection unit arranged in the cold plate inside the liquid cooling server, for monitoring the cooling liquid leakage state of the cold plate in real time, and generating a leakage signal of the cold plate.

[0045] The liquid cooling control system 203 is in communication connection with the cabinet liquid leakage detection system and the server liquid leakage detection system, for receiving and responding to the liquid accumulation signal and the leakage signal of the cold plate, generating an alarm information and a control instruction for triggering a corresponding control processing.

[0046] In the above embodiments, it can be understood that the liquid cooling liquid leakage detection system comprises a cabinet liquid leakage detection system, a server liquid leakage detection system and a liquid cooling control system. Among them, the liquid cooling control system is in communication connection with the cabinet liquid leakage detection system and the server liquid leakage detection system, so that the liquid cooling control system can receive the liquid accumulation signal sent by the cabinet liquid leakage detection system and the leakage signal of the cold plate sent by the server liquid leakage detection system. Further, the liquid cooling control system produces an alarm information and a control instruction for triggering a corresponding control processing according to the received signal after receiving the liquid accumulation signal sent by the cabinet liquid leakage detection system and the leakage signal of the cold plate sent by the server liquid leakage detection system.

[0047] Among them, the cold plate refers to a cooling plate that directly contacts with a heat generating element and is used for conducting heat, and the heat generating element comprises a central processing unit (CPU), a graphics processing unit (GPU), a dual in-line memory module (DIMM) and a voltage regulator (VR). ​

[0048] In some examples, the cabinet bottom plate detection sensor array described above includes: a plurality of bottom plate liquid leakage sensors distributed in a grid or a strip at the bottom of the liquid cooling cabinet, configured to detect the liquid accumulation state of the position where the bottom plate liquid leakage sensor is located, and generate a corresponding bottom plate liquid accumulation signal; and a bottom plate signal aggregation unit in communication connection with the plurality of bottom plate liquid leakage sensors, configured to aggregate the bottom plate liquid accumulation signals and generate a liquid accumulation signal.

[0049] The above examples achieve fine monitoring of the liquid accumulation state of the bottom plate area by deploying distributed bottom plate liquid leakage sensors at the bottom of the liquid cooling cabinet. Specifically, the bottom plate liquid leakage sensor independently detects the liquid accumulation of the area covered by the bottom plate liquid leakage sensor and outputs a corresponding bottom plate liquid accumulation signal, i.e., a local liquid accumulation signal; the bottom plate signal aggregation unit is responsible for receiving and integrating the corresponding bottom plate liquid accumulation signals from the plurality of bottom plate liquid leakage sensors, thereby forming a liquid accumulation signal representing the overall bottom plate liquid accumulation state for subsequent processing by the liquid cooling control system, thereby effectively improving the timeliness and accuracy of liquid leakage detection of the liquid cooling cabinet.

[0050] Further, the bottom plate liquid leakage sensor described in the above examples is at least one of a fiber type liquid leakage sensor, an electrode type liquid leakage sensor, and a capacitive type liquid leakage sensor. It can be understood that the bottom plate liquid leakage sensor can be a fiber type liquid leakage sensor; it can also be a fiber type liquid leakage sensor and an electrode type liquid leakage sensor; it can also be a fiber type liquid leakage sensor and a capacitive type liquid leakage sensor. It should be noted that the specific selection of the bottom plate liquid leakage sensor can be selected according to the embodiment, and the embodiment of the present application does not limit this.

[0051] The embodiment of the present application realizes real-time monitoring of the liquid accumulation state in the liquid cooling cabinet by setting the cabinet bottom detection sensor array at the bottom of the liquid cooling cabinet, and generates a liquid accumulation signal; by setting a cold plate detection unit in the cold plate inside the liquid cooling server, the cooling liquid leakage state of the cold plate is monitored in real time, and a leakage signal of the cold plate is generated; the liquid cooling control system receives and responds to the liquid accumulation signal and the leakage signal of the cold plate, generates an alarm information and a control instruction for triggering corresponding control processing, realizes the liquid leakage detection of the liquid cooling cabinet and the liquid cooling server at the same time, thereby improving the accuracy of the liquid leakage detection and reducing the probability of missing detection.

[0052] Further, in some embodiments, the cold plate detection unit described above includes: a humidity sensor arranged on the cold plate, configured to monitor the humidity state of the cold plate and generate a humidity signal; and a signal processing unit in communication connection with the humidity sensor, configured to receive and respond to the humidity signal and generate a leakage signal of the cold plate.

[0053] In the above embodiments, it can be understood that the cold plate detection unit includes a humidity sensor and a signal processing unit. Among them, the humidity sensor is arranged on the cold plate, which is used to monitor the humidity state of the cold plate in real time, and generate a corresponding humidity signal according to the humidity state. The signal processing unit is in communication connection with the humidity sensor, so as to receive the humidity signal. After receiving the humidity signal, the signal processing unit generates a corresponding leakage signal of the cold plate according to the humidity signal. For example, when the signal processing unit receives a humidity signal of the cold plate greater than a set humidity threshold, the signal processing unit generates a cold plate leakage signal indicating that the cold plate has a leakage. When the signal processing unit receives a humidity signal of the cold plate less than or equal to the set humidity threshold, the signal processing unit generates a cold plate normal signal indicating that the cold plate has no leakage, that is, generates a leakage signal of null value. By monitoring the humidity state of the cold plate in real time, it is determined whether the cold plate has a liquid leakage, so that the potential leakage risk of the cold plate can be found in time, and equipment failure, data loss or system paralysis caused by liquid leakage can be avoided, thereby ensuring stable operation of the liquid cooling system and safety and reliability of the data center.

[0054] On the basis of the above embodiments, the cold plate detection unit further includes a pressure sensor arranged in the cooling liquid flow channel of the cold plate, which is used to monitor the internal pressure change of the cooling liquid flow channel and generate a pressure signal. Correspondingly, the signal processing unit is in communication connection with the pressure sensor and / or the humidity sensor, which is used to receive and respond to the pressure signal and / or the humidity signal, and generate a leakage signal of the cold plate.

[0055] In this embodiment, the cold plate detection unit not only includes a humidity sensor arranged on the cold plate, but also includes a pressure sensor arranged in the cooling liquid flow channel of the cold plate. This means that the signal processing unit needs to be in communication connection with both the humidity sensor and the pressure sensor. When generating the leakage signal of the cold plate, the pressure signal and / or the humidity signal need to be considered.

[0056] For example, when the pressure signal exceeds a preset leakage threshold, the leakage signal can be directly generated according to the pressure signal. When the pressure signal does not exceed the preset leakage threshold, the leakage signal can be generated according to the pressure signal and the humidity signal. When the humidity signal exceeds a preset value, the leakage signal can be directly generated according to the humidity signal. It should be noted that this is only an example.

[0057] By using the humidity sensor and / or the pressure sensor, the potential leakage risk of the cold plate can be found in time according to the embodiments of the present application, and equipment failure, data loss or system paralysis caused by liquid leakage can be avoided, thereby ensuring stable operation of the liquid cooling system and safety and reliability of the data center.

[0058] On the basis of the above-mentioned embodiment, the server liquid leakage detection system further comprises: an interface detection unit arranged at the liquid cooling water inlet interface and the liquid cooling water outlet interface of the liquid cooling server, for monitoring the cooling liquid leakage state of the liquid cooling water inlet interface and the cooling liquid leakage state of the liquid cooling water outlet interface, and generating an interface leakage signal; correspondingly, the liquid cooling control system is used for receiving and responding to the liquid leakage signal, the cooling plate leakage signal and the interface leakage signal, generating an alarm information and a control instruction for triggering a corresponding control process.

[0059] In this embodiment, it can be understood that the server liquid leakage detection system not only needs the cooling plate detection unit arranged in the cooling plate inside the liquid cooling server, but also needs to include the interface detection unit arranged at the liquid cooling water inlet interface and the liquid cooling water outlet interface of the liquid cooling server. That is, on the basis of the above-mentioned embodiment, the interface detection unit is added for monitoring the cooling liquid leakage state of the liquid cooling water inlet interface and the cooling liquid leakage state of the liquid cooling water outlet interface.

[0060] The reason for adding the interface detection unit is that the interface where the cooling plate is connected with the external pipeline is a high-risk area of liquid leakage. Relying solely on the cooling plate detection unit arranged in the cooling plate inside the liquid cooling server may not be able to timely or accurately find the slight leakage at the interface, thereby existing the risk of liquid leakage.

[0061] Further, the above-mentioned interface detection unit is a micro-flow sensor. The micro-flow sensor is used as the interface detection unit in order to more accurately and earlier find the slight liquid leakage of the liquid cooling water inlet interface and the liquid cooling water outlet interface.

[0062] For example, when the liquid cooling water inlet interface and the liquid cooling water outlet interface have slight liquid leakage, the flow of the cooling liquid will change slightly, but this slight change can be captured by the micro-flow sensor and an interface leakage signal is generated in time. This means that the micro-flow sensor can sensitively capture the slight abnormal fluctuation of the flow, so as to generate the interface leakage signal before the liquid leakage has been obviously accumulated or spread.

[0063] The embodiment of the present application can perform targeted and more sensitive monitoring on the liquid cooling water inlet interface and the liquid cooling water outlet interface of the liquid cooling server by adding the interface detection unit, make up for the blind area or deficiency of the cooling plate body detection, further improve the liquid leakage detection coverage range and early warning capability of the whole liquid cooling liquid leakage detection system, and reduce the risk of liquid leakage.

[0064] On the basis of the above-mentioned embodiment, the server liquid leakage detection system further comprises: a flow regulating valve arranged at the liquid cooling water inlet interface of the liquid cooling server, for receiving and responding to the control instruction to adjust the flow of the cooling liquid flowing through the cooling plate of the liquid cooling server.

[0065] In this embodiment, it can be understood that the server liquid leakage detection system also needs to include a flow regulating valve at the liquid cooling water inlet interface of the liquid cooling server, and the flow regulating valve can adjust the flow of the cooling liquid flowing through the cold plate of the liquid cooling server according to the control instruction sent by the liquid cooling control system. Specifically, the actuator of the flow regulating valve receives the control instruction sent by the liquid cooling control system, and the control instruction is usually transmitted in the form of a standardized signal. After receiving the control instruction, the actuator will immediately analyze and respond to the control instruction, and according to the numerical value or type of the control instruction, drive the valve stem to displace accordingly, and the displacement of the valve stem directly changes the relative position of the valve core in the valve seat in the valve inner part. When the valve core moves, it changes the cross-sectional area of the fluid passing through the valve, thereby accurately adjusting the flow of the cooling liquid flowing through the valve.

[0066] For example, when it is detected that the cold plate inside the liquid cooling server has a cooling liquid leakage, the liquid cooling control system will generate a control instruction for triggering the adjustment of the cooling liquid flow, and send the control instruction to the actuator of the flow regulating valve. After receiving the control instruction, the actuator drives the valve stem to displace accordingly, so as to reduce or cut off the flow of the cooling liquid flowing through the valve, thereby minimizing the amount of cooling liquid leakage and reducing the loss caused by the cooling liquid leakage.

[0067] The embodiments of the present application indirectly assist the liquid leakage detection and risk management of the liquid leakage detection system of the liquid cooling server by setting a flow regulating valve at the liquid cooling water inlet interface of the liquid cooling server to accurately adjust the flow of the cooling liquid flowing through the valve.

[0068] Further, in some embodiments, the server liquid leakage detection system further comprises a server internal flow guide structure arranged at the bottom of each liquid cooling server, for collecting the liquid leakage inside the liquid cooling server, and guiding the collected liquid leakage to a preset position. In this embodiment, the server internal flow guide structure is arranged at the bottom of each liquid cooling server, and is used to collect the liquid leakage inside the liquid cooling server, such as the liquid leakage of the cold plate of the liquid cooling server, and accurately guide the collected liquid leakage to a preset position, for example, guide the collected liquid leakage to a special liquid accumulation groove, so as to maximize the protection of the core electronic components of the liquid cooling server from the cooling liquid.

[0069] Optionally, the liquid leakage detection system further comprises a remote monitoring unit in communication connection with the liquid cooling control system, configured to remotely receive the alarm information and send a remote control instruction to the liquid cooling control system according to the alarm information. That is, after the liquid cooling control system generates the alarm information, the alarm information needs to be transmitted to the remote monitoring unit, and the remote monitoring unit is in communication connection with the liquid cooling control system. After receiving the alarm information, the remote monitoring unit sends a remote control instruction to the liquid cooling control system according to the received alarm information. The liquid cooling control system performs corresponding control processing based on the received remote control instruction. It should be noted that when the control instruction generated by the liquid cooling control system and the remote control instruction generated by the remote monitoring unit, the corresponding control processing is executed based on the remote control instruction generated by the remote monitoring unit.

[0070] The embodiment of the present application can realize real-time and remote monitoring and management of the liquid leakage state of the liquid cooling cabinet and the liquid cooling server by arranging the remote monitoring unit in the liquid cooling leakage detection system, so as to ensure that relevant personnel can immediately receive alarm information and respond quickly once liquid leakage occurs, thereby minimizing the damage caused by liquid leakage to the server equipment and ensuring the continuous and stable operation of the data center and data security.

[0071] On the basis of the above-mentioned embodiment, the liquid leakage detection system comprises a display system configured to output the liquid accumulation signal and the leakage signal of the cold plate, and the alarm information. In order to facilitate relevant personnel to timely understand the liquid leakage state of the liquid cooling cabinet and the liquid cooling server, the display system is arranged in the liquid leakage detection system in the embodiment of the present application, and the display system is configured to output the liquid accumulation signal and the leakage signal of the cold plate, and the alarm information. The display system comprises at least one of a display screen, an indicator light, and a loudspeaker, or any combination thereof.

[0072] Next, how to use the liquid cooling leakage detection system provided by the embodiment of the present application will be illustrated. The liquid cooling leakage detection system designs an innovative architecture of double-end collaborative detection. Specifically, a cabinet bottom plate detection sensor array is arranged in each liquid cooling cabinet, and a cold plate detection unit is arranged in the cold plate of each liquid cooling server.

[0073] The cabinet bottom plate detection sensor array comprises a plurality of bottom plate leakage sensors distributed in a grid or a strip along the bottom of the liquid cooling cabinet, and a bottom plate signal aggregation unit in communication connection with the plurality of bottom plate leakage sensors. The bottom plate leakage sensor is at least one of an optical fiber type leakage sensor, an electrode type leakage sensor, and a capacitive type leakage sensor. The cold plate detection unit comprises a humidity sensor arranged in the cold plate, a pressure sensor arranged in the cooling liquid flow channel of the cold plate, and a signal processing unit in communication connection with the humidity sensor.

[0074] Further, the liquid cooling leakage detection system further comprises an interface detection unit arranged at the liquid cooling water inlet interface and the liquid cooling water outlet interface of the liquid cooling server, and the interface detection unit is a micro flow sensor; the liquid cooling leakage detection system further comprises a flow regulating valve arranged at the liquid cooling water inlet interface of the liquid cooling server.

[0075] Further, when it is detected that the liquid cooling cabinet has a leakage and / or the liquid cooling server has a leakage, the liquid cooling control system is used to generate a control instruction for triggering a corresponding control process.

[0076] Figure 3 A control flow diagram of the liquid cooling control system provided by the embodiment of the present application is shown in FIG. 3. Figure 3 As shown in FIG. 3, when it is detected that the liquid cooling server has a leakage during the power-on operation, the liquid cooling control system controls the liquid cooling server to shut down and controls the liquid cooling cabinet to power off.

[0077] When it is detected by the liquid cooling control system that the liquid cooling server has no leakage, the liquid cooling control system controls the liquid cooling cabinet to power on and controls the liquid cooling server to power on; if it is detected by the liquid cooling control system that the liquid cooling server still has a leakage, the liquid cooling control system controls the liquid cooling cabinet to power off and keeps the liquid cooling server in a shutdown state.

[0078] It should be noted that the liquid cooling control system needs to report the situation that the liquid cooling server has a leakage, the state of the liquid cooling server and the state of the liquid cooling cabinet to a remote monitoring unit of a customer, and the remote monitoring unit controls the liquid cooling control system to perform a corresponding control process, for example, controls the liquid cooling control system to prevent the cooling liquid from flowing into the cold plate of the liquid cooling server, that is, to perform a leakage abnormality alarm.

[0079] Further, when it is detected that the liquid cooling cabinet has a leakage during the power-on operation, the control principle of the liquid cooling control system is similar to the principle of detecting the leakage during the power-on operation of the liquid cooling cabinet.

[0080] In summary, the liquid cooling leakage detection system provided by the embodiment of the present application aims to provide a solution for real-time detection and feedback of leakage information for a liquid cooling cabinet, and simultaneously monitors the leakage state of the liquid cooling server and the leakage state of the liquid cooling cabinet when the cooling liquid is circulated to the liquid cooling server. When the liquid cooling server and / or the liquid cooling cabinet has a leakage, the liquid cooling leakage detection system can trigger a safety measure at the first time, such as automatically cutting off the cooling liquid supply or issuing an alarm, so as to effectively control the leakage range, reduce the expansion of the server damage area, and maximize the protection of equipment safety.

Figure 4As shown, the liquid cooling cabinet includes a liquid cooling cabinet body 401, liquid cooling servers 402 arranged on the liquid cooling cabinet body, and a liquid cooling leakage detection system 403 as described in the foregoing embodiments.
