Description

Technical Field

[0001] This application relates to the field of liquid cooling (liquid cooling assisted air cooling) heat dissipation technology, specifically to a detection method and a liquid cooling heat dissipation device. Background Technology

[0002] Liquid cooling is a cooling method that uses liquid to remove heat generated by electronic devices such as computers, servers, and other high-performance hardware. It is more efficient than traditional air cooling. Liquid cooling systems use liquid as a heat transfer medium, with a pump driving the coolant to circulate. The coolant absorbs heat at the heat-generating components, transfers it to the heat sink, and finally dissipates it into the environment.

[0003] Since liquid cooling systems primarily utilize coolant for heat dissipation, there is a risk of coolant leakage, which can damage electronic equipment. In related technologies, the liquid at the leak point within the cooling system piping is brought into contact with a leak sensor. The detection system determines the actual leakage by detecting changes in the sensor's electrical parameters. However, this method suffers from high installation complexity, high cost, slow response time, and low detection resolution.

[0004] Therefore, how to quickly detect coolant leaks while reducing costs is a problem that needs to be addressed. Summary of the Invention

[0005] This application provides a detection method and a liquid cooling heat dissipation device. This method can quickly detect liquid leakage problems in the liquid cooling heat dissipation pipeline while reducing costs.

[0006] In a first aspect, a detection method is provided, which is applied to a liquid cooling heat dissipation device, the liquid cooling heat dissipation device including: a liquid cooling pipeline coated with a detection agent, the liquid cooling pipeline including a first liquid, the method including: determining whether a first gas is generated on the liquid cooling pipeline, the first gas being generated by the reaction between the first liquid leaking from the liquid cooling pipeline and the detection agent, and when the first gas is generated on the liquid cooling pipeline, determining, based on the first gas, that the first liquid in the liquid cooling pipeline has leaked.

[0007] The method provided in this application involves applying a detection agent to a liquid cooling pipeline. When a first liquid in the liquid cooling pipeline leaks, the first liquid and the detection agent react to produce a first gas. By detecting whether the first gas is produced, it can be determined whether the first liquid has leaked. This method can quickly detect whether a leak has occurred while reducing costs.

[0008] In some embodiments, the detection agent can be applied to the entire liquid cooling pipeline. In this implementation, the detection agent is applied to the entire liquid cooling pipeline to detect whether a leak has occurred at any point on the liquid cooling pipeline.

[0009] In some embodiments, the detection agent may be applied to a first location on the liquid cooling pipeline, the first location including at least one of the following locations: a connection point on the liquid cooling pipeline, a welding point on the liquid cooling pipeline, or a point susceptible to external impact.

[0010] In this embodiment of the application, the first position is prone to leakage of the first liquid. There may be one or more first positions. Applying the detection agent only to the first position can improve the detection efficiency and reduce the cost of the detection agent.

[0011] In some embodiments, the liquid cooling heat dissipation device includes a sensor, and determining whether a first gas is generated on the liquid cooling pipeline includes determining that a first gas is generated on the liquid cooling pipeline when the electrical signal of the sensor changes from a first signal to a second signal.

[0012] In this embodiment of the application, the sensor outputs a changing electrical signal after sensing the gas. By installing the sensor in the liquid cooling heat dissipation device, when the sensor's electrical signal changes from a first signal to a second signal, it indicates that a first gas has been generated in the liquid cooling pipeline.

[0013] In some embodiments, the liquid cooling heat dissipation device further includes a detection circuit, wherein determining that the liquid cooling pipeline is leaking based on the first gas includes: the detection circuit receiving an electrical signal change from a sensor, the electrical signal change being used to indicate the changes in the second signal and the first signal; the detection circuit determining that the first liquid in the liquid cooling pipeline is leaking based on the electrical signal change and a preset leak judgment mechanism.

[0014] In this embodiment, the detection circuit, as the processing center, can quickly determine that the first liquid in the liquid cooling pipeline has leaked based on the change in electrical signal and the preset leakage judgment mechanism.

[0015] For example, the preset leakage detection mechanism can be such that when the change in the electrical signal is equal to the change in the second signal and the first signal, it indicates that the first liquid has leaked. For example, the first signal is 0 and the second signal is 1.

[0016] In some embodiments, different detection agents are applied at different first locations, and different first gases correspond to different detection agents. The method further includes: the detection circuit determines the location where the first liquid in the liquid cooling pipeline leaks based on the first gas.

[0017] In this embodiment, different detectors react with the first liquid to produce different gases. By applying different detectors at different first locations, the location of the first liquid leak in the liquid cooling pipeline can be determined arbitrarily, making it easier to quickly locate the leak.

[0018] In some embodiments, the liquid cooling heat dissipation device includes at least one fan, and before the electrical signal of the sensor changes from a first signal to a second signal to determine that a first gas is generated on the liquid cooling pipeline, the above method further includes: the sensor sensing the first gas under the action of at least one fan.

[0019] In this embodiment, driven by at least one fan, the sensor can quickly detect the first gas, preventing the first gas from diffusing to other places and causing the sensor to fail to detect it.

[0020] In some embodiments, the liquid cooling heat dissipation device includes multiple regions, each region corresponding to the air duct of a fan, and each region includes at least one sensor.

[0021] In this embodiment, the liquid cooling heat dissipation device is divided into multiple spatial regions, each corresponding to the air duct of a fan. This ensures that after the first gas is generated, it diffuses to each region. Each region includes a sensor, which ensures that the first gas diffused to each region can be detected. This method can be deployed in different regions to avoid detection blind spots, thereby improving detection accuracy.

[0022] In some embodiments, the distance between the first position and the sensor is less than a preset first threshold, and each first position corresponds to a sensor. The method further includes: determining the location where the first liquid in the liquid cooling pipeline leaks based on the mapping relationship between the sensor that has undergone an electrical signal change and the preset first position of the sensor.

[0023] In this embodiment of the application, a sensor is deployed nearby at the first location. The sensor can quickly detect the first gas and determine the location of the first liquid leak based on the sensor that has a change in electrical signal.

[0024] Secondly, a liquid cooling heat dissipation device is provided, comprising: a liquid cooling pipeline coated with a detection agent, the liquid cooling pipeline containing a first liquid, the liquid cooling heat dissipation device being used to: determine whether a first gas is generated on the liquid cooling pipeline, the first gas being generated by the reaction between the first liquid leaking from the liquid cooling pipeline and the detection agent; and further used to, when the first gas appears on the liquid cooling pipeline, determine, based on the first gas, that the first liquid in the liquid cooling pipeline has leaked.

[0025] The device provided in this application coats a detection agent onto a liquid cooling pipeline. When a first liquid in the liquid cooling pipeline leaks, the first liquid and the detection agent react to produce a first gas. That is, by detecting whether the first gas is produced, it can be determined whether the first liquid has leaked. This method can quickly detect whether a leakage problem has occurred while reducing costs.

[0026] In some embodiments, the liquid cooling device may be a server unit or a server chassis, etc.

[0027] In some embodiments, the detection agent can be applied to the entire liquid cooling pipeline. In this implementation, the detection agent is applied to the entire liquid cooling pipeline to detect whether a leak has occurred at any point on the liquid cooling pipeline.

[0028] In some embodiments, the detection agent may be applied to a first location on the liquid cooling pipeline, the first location including at least one of the following locations: a connection point on the liquid cooling pipeline, a welding point on the liquid cooling pipeline, or a point susceptible to external impact.

[0029] In some embodiments of this application, the first location is prone to leakage of the first liquid. There may be one or more first locations. Applying the detection agent only at the first location can improve detection efficiency and reduce the cost of the detection agent.

[0030] In some embodiments, the liquid cooling heat dissipation device includes a sensor, which determines that the first gas is generated on the liquid cooling pipeline when the electrical signal of the sensor changes from a first signal to a second signal.

[0031] In this embodiment of the application, the sensor will undergo a change in charge after sensing the gas. The change in charge will cause a change in the electrical signal. By installing the sensor in the liquid cooling heat dissipation device, when the electrical signal of the sensor changes from the first signal to the second signal, it indicates that the first gas has been generated in the liquid cooling pipeline.

[0032] In some embodiments, the liquid cooling heat dissipation device further includes a detection circuit, which is used to receive the change in electrical signal sent by the sensor, and the detection circuit is used to determine, based on the change in electrical signal and a preset leakage judgment mechanism, that a first liquid in the liquid cooling pipeline has leaked.

[0033] In this embodiment, the detection circuit, as the processing center, can quickly determine that the first liquid in the liquid cooling pipeline has leaked based on the change in electrical signal and the preset leakage judgment mechanism.

[0034] For example, the preset leakage detection mechanism can be such that when the change in the electrical signal is equal to the change in the second signal and the first signal, it indicates that the first liquid has leaked. For example, the first signal is 0 and the second signal is 1.

[0035] In some embodiments, different detection agents are applied to different first locations, and different detection agents correspond to different first gases. The detection circuit is also used to determine the location where the first liquid in the liquid cooling pipeline leaks based on the first gas.

[0036] In this embodiment, different detectors react with the first liquid to produce different gases. By applying different detectors at different first locations, the location of the first liquid leak in the liquid cooling pipeline can be determined arbitrarily, making it easier to quickly locate the leak.

[0037] In some embodiments, the liquid cooling device includes at least one fan, which is used by the sensor to sense the first gas.

[0038] In this embodiment, driven by at least one fan, the sensor can quickly detect the first gas, preventing the first gas from diffusing to other places and causing the sensor to fail to detect it.

[0039] In some embodiments, the liquid cooling heat dissipation device includes multiple regions, each region corresponding to the air duct of a fan, and each region includes at least one sensor.

[0040] In this embodiment, the liquid cooling heat dissipation device is divided into multiple spatial regions, each corresponding to the air duct of a fan. This ensures that after the first gas is generated, it diffuses to each region. Each region includes a sensor, which ensures that the first gas diffused to each region can be detected. This method can be deployed in different regions to avoid detection blind spots, thereby improving detection accuracy.

[0041] In some embodiments, the distance between the first position and the sensor is less than a preset first threshold, and each first position corresponds to a sensor.

[0064] As the power of server chips increases daily, chip cooling methods have evolved from air cooling to a hybrid air-liquid cooling system, and then to full liquid cooling. Because servers run high-value applications, their reliability requirements are extremely high. Introducing liquid cooling solutions presents a significant challenge to reliable server operation due to the potential for refrigerant leakage. Therefore, the ability to quickly and accurately detect leaks in the cooling system has become a key technology for liquid-cooled servers or liquid-cooled servers that utilize air cooling.

[0065] Air cooling refers to using air as the cooling medium, with a fan forcing air to flow over the fins of a radiator, transferring heat from the heat source to the air. Liquid cooling uses liquid as the cooling medium, as liquids typically have a much higher specific heat capacity than air, allowing them to effectively absorb heat. The liquid is circulated by a pump, absorbing heat from the heat source before dissipating it into the air through a radiator or cooling coil.

[0066] In related technologies, mainstream liquid cooling leak detection schemes deploy leak sensors in the form of strips or ropes at target detection points using methods such as wrapping or adhesive bonding. The liquid (working fluid) leaking from the cooling system piping comes into direct contact with the leak sensor, affecting its electrical parameters (such as resistance, current, and voltage). The detection system detects these changes in electrical parameters to determine if a leak has occurred.

[0067] However, this solution has drawbacks such as high installation complexity, high cost, slow detection response time, low detection resolution, and significant losses due to working fluid leakage. Improving the detection resolution or shortening the response time would inevitably lead to a sharp increase in process complexity and cost.

[0068] In conclusion, how to quickly detect leaks in the cooling system piping while reducing costs is a key area of ​​focus.

[0069] In view of this, this application provides a detection method, which includes: applying a detection agent to a liquid cooling heat dissipation pipeline, the detection agent reacting with the working fluid to generate gas, a sensor sensing the gas and causing a change in the sensor's electrical signal, and a detection circuit determining whether the liquid cooling heat dissipation pipeline is leaking based on the amount of change in the electrical signal.

[0070] Before introducing the testing method provided in this application, we will first introduce the liquid cooling heat dissipation device to which this testing method is applicable.

[0071] Figure 1 A schematic diagram of an example liquid cooling heat dissipation device provided in an embodiment of this application is shown, as follows: Figure 1 As shown, the liquid cooling heat dissipation device includes: a fan, liquid cooling pipes, and a detection device.

[0072] The liquid cooling heat dissipation pipeline has a detection agent coating layer, on which a detection agent is applied. This detection agent can react chemically with the working fluid in the pipeline to produce gas.

[0073] It should be noted that the liquid cooling pipeline mentioned in this application can also refer to the liquid cooling auxiliary air cooling pipeline.

[0074] In some embodiments, the detection agent can be applied to the entire liquid cooling pipeline. In this implementation, the detection agent is applied to the entire liquid cooling pipeline to detect whether a leak has occurred at any point on the liquid cooling pipeline.

[0075] In other embodiments, the detection agent may be applied to a first location on the liquid cooling line, the first location including at least one of the following locations: a connection point on the liquid cooling line, a welding point on the liquid cooling line, or a point susceptible to external impact.

[0076] In some embodiments of this application, the first location is prone to leakage of the first liquid. There may be one or more first locations. Applying the detection agent only at the first location can improve detection efficiency and reduce the cost of the detection agent.

[0077] In some embodiments, the liquid cooling heat dissipation device includes a sensor, which determines that a first gas is generated on the liquid cooling pipeline when the electrical signal of the sensor changes from a first signal to a second signal.

[0078] In this embodiment of the application, the sensor will undergo a change in charge after sensing the gas. The change in charge will cause a change in the electrical signal. By installing the sensor in the liquid cooling heat dissipation device, when the electrical signal of the sensor changes from the first signal to the second signal, it indicates that the first gas has been generated in the liquid cooling pipeline.

[0079] In some embodiments, the liquid cooling heat dissipation device further includes a detection circuit, which is used to receive the change in electrical signal sent by the sensor, and the detection circuit is used to determine that a first liquid leak has occurred in the liquid cooling pipeline based on the change in electrical signal and a preset leakage judgment mechanism.

[0080] In this embodiment, the detection circuit, as the processing center, can quickly determine that the first liquid in the liquid cooling pipeline has leaked based on the change in electrical signal and the preset leakage judgment mechanism.

[0081] For example, the preset leakage detection mechanism can be such that when the change in the electrical signal is equal to the change in the second signal and the first signal, it indicates that the first liquid has leaked. For example, the first signal is 0 and the second signal is 1.

[0082] In some embodiments, different detection agents are applied to different first locations, and different detection agents correspond to different first gases. The detection circuit is also used to determine the location where the first liquid in the liquid cooling pipeline leaks based on the first gas.

[0083] In this embodiment, different detectors react with the first liquid to produce different gases. By applying different detectors at different first locations, the location of the first liquid leak in the liquid cooling pipeline can be determined arbitrarily, making it easier to quickly locate the leak.

[0084] In some embodiments, the liquid cooling device includes at least one fan, which is used by the sensor to sense the first gas.

[0085] In this embodiment, driven by at least one fan, the sensor can quickly detect the first gas, preventing the first gas from diffusing to other places and causing the sensor to fail to detect it.

[0086] In some embodiments, the liquid cooling heat dissipation device includes multiple regions, each region corresponding to the air duct of a fan, and each region includes at least one sensor.

[0087] In this embodiment, the liquid cooling heat dissipation device is divided into multiple spatial regions, each corresponding to the air duct of a fan. This ensures that after the first gas is generated, it diffuses to each region. Each region includes a sensor, which ensures that the first gas diffused to each region can be detected. This method can be deployed in different regions to avoid detection blind spots, thereby improving detection accuracy.

[0088] In some embodiments, the distance between the first position and the sensor is less than a preset first threshold, each first position corresponds to a sensor, and the detection circuit is further used to determine the location where the first liquid leaks in the liquid cooling pipeline based on the mapping relationship between the sensor that has undergone an electrical signal change and the preset first position of the sensor.

[0089] In this embodiment of the application, a sensor is deployed nearby at the first location. The sensor can quickly detect the first gas and determine the location of the first liquid leak based on the sensor that has a change in electrical signal.

[0090] Optionally, the liquid cooling device may also include an alarm. When the detection circuit determines that there is a liquid leak or the gas concentration exceeds a preset threshold, the detection circuit can send a signal to the alarm, thereby instructing the alarm to issue a warning to the staff and remind the operator to take action.

[0091] In some embodiments, the liquid cooling device may be a server chassis or a server unit, etc.

[0092] The detection method provided in the embodiments of this application will be described in detail below.

[0093] Figure 2 This is a schematic flowchart of a detection method provided in an embodiment of this application, as shown below. Figure 2 As shown, the method 200 includes steps S210-S220.

[0094] S210. Determine whether a first gas will be generated on the liquid cooling pipeline. This first gas is generated by the reaction between the first liquid leaking from the liquid cooling pipeline and the detection agent.

[0095] In this embodiment, a detection agent is coated on the liquid cooling heat dissipation pipeline. When the liquid in the pipeline leaks at a certain point, it comes into contact with the detection agent outside the pipeline and produces a chemical reaction to generate a first gas.

[0096] In some embodiments, the liquid in the liquid cooling pipes can be water, deionized water, glycol-based coolant, mineral oil or synthetic oil, fluorinated liquid, etc. Of course, other liquids can also be used in the liquid cooling pipes, and this application embodiment does not specifically limit the type of liquid.

[0097] It should be noted that the detection agent on the liquid cooling heat dissipation pipeline refers to a detection agent that can chemically react with the liquid in the liquid cooling heat dissipation pipeline to generate a first gas. Therefore, the embodiments of this application do not specifically limit the type of detection agent.

[0098] It should also be noted that, depending on the selection of the liquid and the detection agent in the liquid cooling heat dissipation pipeline, the first gas can be of various types. Therefore, the embodiments of this application do not specifically limit the first gas generated.

[0099] In one possible implementation, a detection agent can be applied to the entire pipeline of the liquid cooling system, in which a first gas can be generated when a leak occurs anywhere in the pipeline.

[0100] In another possible implementation, a detection agent can be applied to a first location on the liquid cooling pipeline, which is a location prone to liquid leakage. For example, the first location includes at least one of the following: a connector, a solder joint, or a point susceptible to external impact.

[0101] In this embodiment of the application, liquid in the pipeline is prone to leakage at connectors, welding points or places susceptible to external impact. Therefore, a detection agent is applied to the location where liquid leakage is likely to occur. When liquid leaks, a first gas can be generated, which can save costs.

[0102] In some embodiments of this application, the liquid cooling heat dissipation device includes a detection device that can determine whether a first gas is generated on the liquid cooling pipeline.

[0103] Furthermore, the detection device may include a sensor and a detection circuit. The sensor can sense the first gas. After the sensor senses the first gas, the electrical signals such as voltage, current or resistance change. That is, the sensor changes the electrical signal from the first signal to the second signal, and the sensor sends the change in electrical signal to the detection circuit.

[0104] In some possible implementations, the sensor involved in the embodiments of this application may be a gas sensor.

[0105] For example, the first signal of the sensor can be 0, and when the second signal output by the sensor is 1, the sensor sends the change in the electrical signal to the detection circuit.

[0106] Furthermore, the liquid cooling device may also include a fan, a first gas generated by the reaction of the detection agent and the liquid leaking from the pipeline, which can be captured by the sensor in the detection device under the propulsion of the fan airflow.

[0107] It should be understood that there may be one or more fans, and the number of fans is not specifically limited in the embodiments of this application.

[0108] S220. When a first gas is generated in the liquid cooling pipeline, based on the first gas, it is determined that a first liquid in the liquid cooling pipeline is leaking.

[0109] In this embodiment of the application, the liquid cooling heat dissipation device can determine that there is a leak in the liquid cooling pipeline based on the first gas.

[0110] In one possible implementation, the detection circuit included in the liquid cooling device determines whether leakage occurs on the liquid cooling pipeline based on the change in electrical signal sent by the sensor and a pre-set strategy.

[0111] Optionally, the pre-set strategy can be that when the sensor outputs a first signal, it indicates that the liquid cooling pipeline is not leaking, and when the sensor outputs a second signal, it indicates that the liquid cooling pipeline is leaking. For example, the first signal can be 0 and the second signal can be 1.

[0112] Alternatively, if the sensor outputs the second signal during the first time period, it indicates that the liquid cooling pipeline is leaking; or, if the sensor outputs the second signal during the second time period, it indicates that the liquid cooling pipeline is leaking.

[0113] It should be noted that the first time period can be set according to specific circumstances, and this application embodiment does not impose specific limitations on it. Similarly, the second time period can also be set according to specific circumstances, and this application embodiment does not impose specific limitations on it.

[0114] It should also be noted that the above is an example of a preset leakage judgment mechanism. The preset leakage judgment mechanism can also be other judgment mechanisms, and the embodiments of this application do not specifically limit them.

[0115] The method provided in this application embodiment involves applying a detection agent to the liquid cooling pipeline and detecting whether a first gas is generated on the liquid cooling pipeline. When the first gas is generated on the pipeline, it indicates that there is liquid leakage on the liquid cooling pipeline. This method can quickly detect whether the liquid cooling pipeline is leaking while reducing costs.

[0116] Figure 3 A schematic diagram of an example liquid cooling heat dissipation device is shown, such as Figure 3 As shown, pipe A indicates that the entire pipe is coated with a detection agent. When liquid leaks, the detection agent and the leaking liquid react chemically to generate a first gas (such as...). Figure 3 (1) In the above, the first gas is sensed by the sensor in the detection device under the action of the fan. After the sensor senses the first gas, the electrical signal changes. The sensor sends the change in electrical signal to the detection circuit. The detection circuit determines whether the liquid cooling heat dissipation pipe has leaked based on the change in electrical signal and the preset leakage judgment mechanism.

[0117] Alternatively, pipe B indicates that a detection agent is applied at at least one first location. When liquid leaks at this first location, the detection agent and the leaking liquid react chemically to generate a first gas. The first gas is detected by a sensor in the detection device under the action of a fan. After the sensor detects the first gas, the electrical signal changes. The sensor sends the change in electrical signal to the detection circuit. The detection circuit determines whether the liquid cooling heat dissipation pipe has leaked based on the change in electrical signal and a preset leakage judgment mechanism.

[0118] This application also provides another detection method, which involves applying different detection agents to different locations. The different detection agents react chemically with the leaked liquid to produce different gases. The liquid heat dissipation device can determine the location of the liquid leak based on the different gases.

[0119] In some embodiments, different detection agents are applied at different first locations on the liquid cooling heat dissipation pipeline. When the liquid in the pipeline leaks at different first locations, it comes into contact with the detection agent outside the pipeline and produces a chemical reaction, generating different first gases.

[0120] It should be understood that if different detection agents are applied to different locations, then when the liquid leaks, the different detection agents will react chemically with the liquid to produce different primary gases.

[0121] For example, Figure 4 A schematic diagram of an example liquid cooling heat dissipation device is shown, such as Figure 4 As shown, different detection agents are applied to locations on the pipes of the liquid cooling heat dissipation device where leaks are likely to occur. For example, detection agent 1 is applied at location 1, detection agent 2 is applied at location 2, and detection agent 3 is applied at location 3.

[0122] Assuming a liquid leak occurs at location 1, the liquid and detection agent 1 will react chemically to produce gas 1. Assuming a liquid leak occurs at location 2, the liquid and detection agent 2 will react chemically to produce gas 2. Assuming a liquid leak occurs at location 3, the liquid and detection agent 3 will react chemically to produce gas 3. Therefore, the first gas refers to any one of gas 1, gas 2, or gas 3.

[0123] In some embodiments of this application, the liquid cooling heat dissipation device includes a detection device that can detect a first gas.

[0124] Furthermore, the detection device may include sensors and detection circuits. Since there may be multiple types of the first gas, the detection device may include one or more sensors.

[0125] Specifically, when the detection device includes one type of sensor, that sensor can detect different gases; when the detection device includes multiple types of sensors, each sensor is sensitive to the aforementioned gas and generates a change in electrical signal.

[0126] Furthermore, the sensor detects the first gas and sends the change in electrical signal to the detection circuit.

[0127] Furthermore, the liquid cooling device may also include a fan, and the first gas generated by the detection agent and the leaked liquid can be captured by a sensor in the detection device under the propulsion of the fan airflow. For example, there is one or more fans.

[0128] See also Figure 4 Gas 1, Gas 2, or Gas 3, propelled by a fan, is sensed by a sensor in the detection device (e.g., sensor 1, sensor 2, or sensor 3, not shown in the figure). The sensor that generates a change in electrical signal then sends the amount of that change to the detection circuit.

[0129] In this embodiment of the application, since different detection agents are applied to different locations, the location of a leak in the liquid cooling pipeline can be determined based on the type of gas.

[0130] In some embodiments, after receiving a change in the electrical signal from the sensor, the detection circuit determines the second gas and, based on the mapping relationship between the second gas and the sensor, determines the location of the leak in the liquid cooling pipeline.

[0131] After the detection circuit acquires the change in the electrical signal from the sensor, it determines the location of the leak in the liquid cooling pipeline based on the preset leak detection mechanism and the sensor mapping table.

[0132] In some embodiments, the detection circuit can determine the location of the leak based on the pre-defined location sensed by each sensor. For example, the sensor map could indicate that sensor 1 is responsible for sensing gas 1 at location 1, sensor 2 is responsible for sensing gas 2 at location 2, and sensor 3 is responsible for sensing gas 3 at location 3. If the electrical signal of sensor 1 changes, the detection circuit can determine that a leak has occurred at location 1; if the electrical signal of sensor 2 changes, the detection circuit can determine that a leak has occurred at location 2; and if the electrical signal of sensor 3 changes, the detection circuit can determine that a leak has occurred at location 3.

[0133] It should be understood that the first position includes position 1, position 2 and position 3, and the first gas includes gas 1, gas 2 and gas 3.

[0134] This application also provides another detection method, which avoids detection blind spots and improves detection accuracy by deploying multiple sensors in different areas within the liquid cooling heat dissipation device.

[0135] It should be understood that when a leak occurs in the liquid cooling pipeline, and a chemical reaction occurs between the leaking liquid and the detection agent outside the pipeline, generating a first gas, uneven diffusion of this first gas can affect the accuracy of the detection device due to the sensor's placement. Therefore, deploying sensors in multiple locations within the liquid cooling system can maximize detection accuracy.

[0136] In some embodiments, the air duct of the liquid cooling heat dissipation device can be divided into regions, and one or more sensors can be deployed in each region. When the first gas is generated, the first gas is sensed by the sensor in any region under the impetus of the airflow in the chassis.

[0137] For example, Figure 5 A schematic diagram of an example liquid cooling heat dissipation device is shown, such as... Figure 5 As shown, the server chassis includes four fans, each corresponding to a different airflow path. These airflow paths divide the space of the liquid cooling system into four zones. Figure 5 As can be seen, fan 1 corresponds to area A, fan 2 to area B, fan 3 to area C, and fan 4 to area D. When a liquid leak occurs in the pipeline, the leaking liquid reacts chemically with the detection agent outside the pipeline, producing a first gas (such as...). Figure 5 In the process, gas 1 is propelled by the airflow from any one or more of fans 1, 2, 3, and 4, and sensed by any one or more of sensors A, B, C, and D in a detection device located downstream of the airflow direction. When sensing the gas, the sensors generate changes in electrical parameters, and transmit these changes to the detection circuit. The detection circuit determines whether a liquid leak is occurring based on the changes in the electrical signal and a preset leak detection mechanism. This implementation method maximizes detection accuracy by deploying sensors in multiple locations.

[0138] In some embodiments, sensors are deployed near the application point of the detection agent on the liquid-cooled heat dissipation pipeline to accurately identify the location of leaks and avoid missed detections.

[0139] In one possible implementation, the distance between each first position and its corresponding sensor is less than or equal to a preset first threshold, and each first position corresponds to one sensor. The detection circuit determines the location of the first liquid leak in the liquid-cooled pipeline based on a mapping table between sensors that have undergone electrical signal changes and sensors at preset first positions.

[0140] It should be noted that the first threshold can be set according to specific circumstances, and this application embodiment does not impose specific limitations on it.

[0141] Indicative Figure 6 Another example of a liquid cooling heat dissipation device is shown in the schematic diagram, such as... Figure 6 As shown, there are three points A, B, and C on the liquid cooling pipeline coated with detection agent. Sensor A is deployed at point A, sensor B is deployed at point B, and sensor C is deployed at point C.

[0142] Specifically, the distance between the detection agent application point A and the sensor A is less than or equal to a preset first threshold, the distance between the detection agent application point B and the sensor B is less than or equal to a preset first threshold, and the distance between the detection agent application point C and the sensor C is less than or equal to a preset first threshold.

[0143] The pre-defined mapping table of sensors at the first location indicates that sensor A is deployed at detection agent application point A, sensor B is deployed at detection agent application point B, and sensor C is deployed at detection agent application point C. The detection circuit can determine that leakage has occurred at detection agent application point A based on the change in electrical signal reported by sensor A, or at detection agent application point B based on the change in electrical signal reported by sensor B, or at detection agent application point C based on the change in electrical signal reported by sensor C. This implementation method can accurately identify the location of leaks and avoid missed detections.
