[0002] The rise of high-density computing, driven by the widespread adoption of technologies like cloud computing, big data, and artificial intelligence, has led to a continuous improvement in server performance, resulting in a significant increase in energy consumption. In this context, traditional air cooling is no longer sufficient for the development of high-density computing. An increasing number of servers are adopting liquid cooling technology.

[0051] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0052] In practical applications, a cold plate liquid cooling server may refer to a server component that uses liquid cooling to cool down server components; it may include server components and cold plate liquid cooling components, and the server components may include one or more servers.

[0053] The cold plate liquid cooling component may include a first component and a second component; wherein the first component may be plate-shaped and contact the servers in the server component in an alternating arrangement; the first component may be a hollow structure so that the cooling liquid flowing therethrough may contact the server component, thereby achieving cooling treatment of the server component.

[0054] The second component in the cold plate liquid cooling component can be connected to the first component; on the one hand, the second component can receive the coolant output by the first component that absorbs the heat emitted by the server components and cool them down; on the other hand, the second component can re-transfer the cooled coolant to the first component so that the first component can cool the server components with the cooled coolant.

[0055] During the process of cooling server components, the cold plate liquid cooling components may become damaged due to long-term use, causing the coolant inside to leak; if the coolant comes into contact with the server components, it may cause irreversible damage to the server components, and in severe cases, even a fire may occur.

[0056] To avoid this situation, an embodiment of the present invention provides a control method for a cold plate liquid-cooled server. In this method, a coolant circulation switch can be pre-installed at the liquid inlet of a first component. During operation, the cold plate liquid-cooled server can monitor in real time the first flow rate of coolant supplied from a second component to the first component and the second flow rate of coolant supplied from the first component to the second component. Based on the first and second flow rates, the method determines whether a coolant leak has occurred in the portion of the cold plate liquid-cooled component that contacts server components.

[0057] If a coolant leak is detected in the portion of the cold plate liquid cooling component that contacts the server component, the coolant circulation switch provided at the liquid inlet end of the first component can be turned off; by stopping the supply of coolant to the first component, further leakage of coolant from the damaged portion of the first component can be avoided, thereby preventing damage to the server component.

[0058] Reference Figure 1 , showing a step flow chart of a control method for a cold plate liquid cooling server according to an embodiment of the present invention, the cold plate liquid cooling server may include a server component and a cold plate liquid cooling component, the cold plate liquid cooling component including a first component and a second component; the first component is in contact with the server component and is used to cool the server component by the coolant flowing through it; the second component is used to cool the coolant output by the first component and output the cooled coolant to the first component; a coolant circulation switch is arranged at the liquid inlet end of the first component.

[0059] Specifically, the following steps may be included:

[0060] Step 101: Determine first flow data of the coolant supplied from the second component to the first component, and second flow data of the coolant output from the first component to the second component.

[0061] In practical applications, in order to monitor whether the first component in contact with the server component has a coolant leak, the state of the coolant in the first component may be detected.

[0062] Specifically, the state of the coolant delivered from the second component to the first component and the state of the coolant output from the first component to the second component may be monitored, and based on these two states, it may be determined whether the coolant in the first component is leaking.

[0063] As an example, the flow rate of the coolant delivered by the second component to the first component can be detected in real time, and the first flow rate data of the coolant delivered by the second component to the first component can be determined; the first flow rate data can refer to the volume of the coolant delivered by the second component to the first component per unit time.

[0064] At the same time, the flow rate of the coolant output from the first component to the second component can be detected in real time, and the second flow rate data of the coolant output from the first component to the second component can be determined; the second flow rate data can refer to the volume of the coolant output from the first component to the second component per unit time.

[0065] As another example, the pressure value of the coolant at the liquid inlet end of the first component and the pressure value of the coolant at the liquid inlet end of the second component can also be detected in real time; or, other states of the coolant that can be used to determine whether the coolant is leaking can also be monitored, and this embodiment of the present invention is not limited to this.

[0066] In practical applications, the first flow rate data may be the flow rate of the coolant at the liquid inlet of the first component, the flow rate of the coolant at the liquid inlet of the coolant circulation switch, or the flow rate of the coolant at the liquid outlet of the second component. The second flow rate data may be the flow rate of the coolant at the liquid outlet of the first component or the flow rate of the coolant at the liquid inlet of the second component, and this is not limited in the present embodiment.

[0067] like Figure 2 As shown, the flow rate of the coolant flowing into the coolant circulation switch can be used as the first flow rate data, and the flow rate of the coolant flowing out of the first component can be used as the second flow rate data.

[0068] Step 102: Calculate a target difference between the first flow data and the second flow data, and determine a relationship between the target difference and a preset difference threshold.

[0069] After determining the first flow data and the second flow data, a difference between the first flow data and the second flow data may be calculated and used as a target difference. The target difference may then be compared with a preset difference threshold.

[0070] As an example, the preset difference threshold can be set according to actual conditions, for example, it can be set to 0, or it can be set to other numbers, which is not limited in the embodiment of the present invention.

[0071] In practical applications, the relationship between the target difference and the preset difference threshold may include: the target difference is less than the preset difference threshold, and the target difference is not less than the preset difference threshold.

[0072] Step 103: When the target difference is less than the preset difference threshold, determine that the first component does not leak.

[0073] If the relationship between the target difference and the preset difference threshold is "the target difference is less than the preset difference threshold", it can be indicated that the flow rate of coolant supplied from the second component to the first component at this time is the same as the flow rate of coolant output from the first component to the second component; therefore, it can be determined that the first component in contact with the server component has not leaked.

[0074] Step 104: When the target difference is not less than the preset difference threshold, it is determined that the first component leaks.

[0075] If the relationship between the target difference and the preset difference threshold is "the target difference is not less than the preset difference threshold", it can be said that the flow rate of coolant supplied from the second component to the first component at this time is different from the flow rate of coolant output from the first component to the second component.

[0076] In actual applications, the reason why the flow rate of coolant supplied from the second component to the first component is different from the flow rate of coolant output from the first component to the second component may be that the first component leaks, which in turn causes the coolant to leak out of the first component, resulting in the flow rate of coolant supplied from the second component to the first component being different from the flow rate of coolant output from the first component to the second component.

[0077] Therefore, when it is determined that the target difference is not less than the preset difference threshold, it can be determined that the first component in contact with the server component has leaked.

[0078] Step 105: When it is determined that the first component leaks, close the coolant circulation switch.

[0079] If it is determined that the coolant in the first component has leaked, in order to prevent the first component from continuing to leak coolant, the coolant circulation switch deployed at the liquid inlet end of the first component can be turned off to prevent the second component from continuing to supply coolant to the first component.

[0080] As an example, one or more pumps may be deployed in the cold plate liquid cooling component to push the coolant to move between the first component and the second component; when the coolant circulation switch is turned off, the pump deployed in the cold plate liquid cooling component may continue to push the remaining coolant in the first component to move to the second component to prevent the remaining coolant in the first component from continuing to leak, causing further damage to the server components due to the coolant leakage, thereby reducing the losses caused by the coolant leakage.

[0081] In actual applications, the flow rate of the coolant may change due to changes in temperature. In order to avoid turning off the coolant circulation switch due to an erroneous determination that a leak has occurred in the first component, thereby affecting the heat dissipation of the server component, a preset difference threshold with a certain degree of redundancy can be set. For example, a preset difference threshold greater than 0 can be set, and this is not limited in the embodiment of the present invention.

[0082] In actual applications, if the circuits in a running server component come into contact with leaked coolant, it may cause damage to the circuits in the server component or even cause a fire. To further avoid the above situation, in one embodiment of the present invention, when it is determined that a leak has occurred in the first component, the power supply of the server component is turned off.

[0083] Specifically, if a leak is determined in the first component, a shutdown command can be sent to the server component's power supply to prevent damage to the server component's circuits, or even fire, thereby stopping power supply to the server component. Compared to a running server component, even if the coolant corrodes the powered-off server component, it will not cause a circuit breakage within the server component, which could lead to a fire. This further reduces losses caused by coolant leaks.

[0084] On the other hand, in order to restore the operation of the cold plate liquid cooling server as soon as possible, an embodiment of the present invention may further include the following steps:

[0085] When it is determined that the first component leaks, an alarm message is generated; and the alarm message is pushed according to a preset push mechanism.

[0086] In actual applications, in order to solve the coolant leakage problem of the first component as soon as possible and restore the operation of the cold plate liquid cooling server as soon as possible, an alarm message can be generated when it is determined that the coolant leakage problem occurs in the first component; the alarm message can be used to prompt the staff to inspect and repair the first component.

[0087] After the alarm information is generated, it can be pushed according to a preset push mechanism; the preset push mechanism can be set according to actual conditions, for example: it can be pushed to the interface of the background detection system, or it can be an alarm sound, or it can be a flashing warning light. The embodiment of the present invention does not limit this.

[0088] As an example, a computer room may have multiple cold plate liquid cooling servers deployed, and each cold plate liquid cooling server may have a corresponding first component. When generating an alarm message, the cold plate liquid cooling server corresponding to the corresponding component can be determined first. Then, a targeted alarm message is generated so that the staff can promptly know which cold plate liquid cooling server's first component has a coolant leak, thereby enabling the staff to conduct targeted maintenance.

[0089] In an embodiment of the present invention, a coolant circulation switch can be pre-deployed at the liquid inlet end of the first component of the cold plate liquid cooling component; during the operation of the cold plate liquid cooling server, the first flow data of the coolant delivered by the second component to the first component and the second flow data of the coolant output by the first component to the second component can be determined; the target difference between the first flow data and the second flow data is calculated, and the relationship between the target difference and the preset difference threshold is determined; when the target difference is less than the preset difference threshold, it is determined that the first component has not leaked; when the target difference is not less than the preset difference threshold, it is determined that the first component has leaked; when it is determined that the first component has leaked, the coolant circulation switch is turned off. Through the embodiment of the present invention, the server components in the cold plate liquid cooling server are protected, and damage to the server components due to coolant leakage is avoided.

[0090] It should be noted that for the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.

[0091] Reference Figure 3 , shows a schematic structural diagram of a cold plate type liquid cooling component according to an embodiment of the present invention; Figure 3 As shown, the cold plate liquid cooling component may include a first component, a second component, a detection module, a joint control device and a sensor module.

[0092] Among them, the cold plate liquid cooling component can be used to cool the server components (not shown in the figure) to prevent the server components from being affected by the performance of the server components due to excessively high temperatures during operation, and to prevent the server components from being damaged due to excessively high temperatures.

[0093] In one embodiment of the present invention, the first component is in contact with the server component and is used to cool the server component by allowing the coolant to flow therethrough. A coolant circulation switch is disposed at the liquid inlet end of the first component.

[0094] In practical applications, the first component in the cold plate liquid cooling component can be plate-shaped and in contact with the servers in the server component in an staggered arrangement; the first component can be a hollow structure so that the coolant flowing through it can contact the server component, thereby achieving cooling treatment of the server component.

[0095] In order to facilitate the control of the cold plate liquid cooling component, a coolant circulation switch can be deployed at the liquid inlet end of the first component; when the coolant circulation switch is closed, the coolant can be prevented from continuing to be delivered to the first component, thereby preventing the server components in contact with the first component from being damaged due to coolant leakage from the first component; when the coolant circulation switch is turned on, the coolant can circulate between the first component and the second component, thereby achieving cooling treatment for the server components.

[0096] In one embodiment of the present invention, the liquid inlet of the second component is connected to the liquid outlet of the first component, and the liquid outlet of the second component is connected to the liquid inlet of the first component; the second component is used to cool the coolant output by the first component and output the cooled coolant to the first component.

[0097] In actual applications, the liquid inlet end of the second component can be connected to the liquid outlet end of the first component, so that the second component receives the coolant output by the first component that absorbs the heat emitted by the server component during operation; after receiving the coolant output by the first component that absorbs the heat emitted by the server component during operation, the second component can cool the coolant to obtain the cooled coolant.

[0098] In addition, the liquid outlet of the second component can be connected to the liquid inlet of the first component so that the second component can transport the cooling liquid after cooling to the first component, so that the first component can continue to absorb the heat emitted by the server component during operation through the cooling liquid after cooling.

[0099] During the process of cooling server components, the cold plate liquid cooling components may become damaged due to long-term use, causing the coolant inside to leak; if the coolant comes into contact with the server components, it may cause irreversible damage to the server components, and in severe cases, even a fire may occur.

[0100] In order to avoid the occurrence of the above situation, an embodiment of the present invention provides a cold plate liquid cooling component, which not only includes a first component and a second component, but also can include a detection module, a joint control device and a sensor module; the sensor module can be used to detect and determine the first flow data of the coolant delivered by the second component to the first component, and detect and determine the second flow data of the coolant output by the first component to the second component; the detection module can determine whether a coolant leak occurs in the part of the cold plate liquid cooling component that contacts the server component based on the first flow data and the second flow data determined by the sensor module.

[0101] When the detection module determines that a coolant leak has occurred in the portion of the cold plate liquid cooling component that contacts the server component, it can send an instruction to the joint control device so that the joint control device controls the coolant circulation switch deployed at the liquid inlet end of the first component to turn off. By stopping the supply of coolant to the first component, it can prevent the damaged portion of the first component from continuing to leak coolant, thereby preventing damage to the server component.

[0102] In one embodiment of the present invention, the sensor includes a first sensor and a second sensor, the first sensor is located at an end of the coolant circulation switch away from the server component, and the second sensor is located at the liquid outlet end of the first component; the first sensor is used to determine first flow data of the coolant flowing into the coolant circulation switch; the second sensor is used to determine second flow data of the coolant flowing out of the first component.

[0103] In practical applications, the first sensor and the second sensor may be flow sensors, and the first sensor and the second sensor may be used to detect the flow rate of the coolant flowing through the cold plate liquid cooling component.

[0104] The first sensor can be deployed at one end of the coolant circulation switch away from the server component to detect and determine the first flow data of the coolant delivered by the second component to the first component; the first flow data can be the flow rate of the coolant flowing into the coolant circulation switch.

[0105] The second sensor may be disposed at the liquid outlet of the first component to detect and determine second flow data of the coolant output from the first component to the second component; the second flow data may be the flow rate of the coolant flowing out of the first component.

[0106] In one embodiment of the present invention, the detection module is connected to the sensor and the joint control device respectively; the detection module is used to obtain first flow data and second flow data from the sensor; calculate the target difference between the first flow data and the second flow data, and determine the relationship between the target difference and a preset difference threshold; when the target difference is less than the preset difference threshold, it is determined that the first component has not leaked; when the target difference is not less than the preset difference threshold, it is determined that the first component has leaked, and a target instruction to turn off the coolant circulation switch is sent to the joint control device.

[0107] In practical applications, the detection module may be connected to the first sensor, the second sensor and the joint control device respectively, so as to obtain flow data from the first sensor and the second sensor, and send control instructions to the joint control device.

[0108] After acquiring first flow data from the first sensor and second flow data from the second sensor, the detection module may calculate a difference between the first flow data and the second flow data and use the difference as a target difference. The target difference may then be compared with a preset difference threshold.

[0109] As an example, the preset difference threshold can be set according to actual conditions, for example, it can be set to 0, or it can be set to other numbers, which is not limited in the embodiment of the present invention.

[0110] In practical applications, the relationship between the target difference and the preset difference threshold may include: the target difference is less than the preset difference threshold, and the target difference is not less than the preset difference threshold.

[0111] If the relationship between the target difference and the preset difference threshold is "the target difference is less than the preset difference threshold", it can be said that the flow rate of the coolant supplied by the second component to the first component at this time is the same as the flow rate of the coolant output by the first component to the second component; therefore, the detection module can determine that there is no leakage in the first component in contact with the server component.

[0112] If the relationship between the target difference and the preset difference threshold is "the target difference is not less than the preset difference threshold", it can be said that the flow rate of coolant supplied from the second component to the first component at this time is different from the flow rate of coolant output from the first component to the second component.

[0113] In actual applications, the reason why the flow rate of coolant supplied from the second component to the first component is different from the flow rate of coolant output from the first component to the second component may be that the first component leaks, which in turn causes the coolant to leak out of the first component, resulting in the flow rate of coolant supplied from the second component to the first component being different from the flow rate of coolant output from the first component to the second component.

[0114] Therefore, when the detection module determines that the target difference is not less than the preset difference threshold, it can be determined that the first component in contact with the server component has leaked.

[0115] When the detection module determines that the coolant leaks from the first component, it can generate a target instruction for controlling the coolant circulation switch to be turned off; and send the target instruction to the joint control device.

[0116] In one embodiment of the present invention, the joint control device is used to turn off the coolant circulation switch when receiving the target instruction.

[0117] In actual applications, after receiving the target instruction, the joint control device can turn off the coolant circulation switch deployed at the liquid inlet end of the first component to prevent the second component from continuing to supply coolant to the first component.

[0118] In actual applications, if the circuits in a running server component come into contact with leaked coolant, it may cause damage to the circuits in the server component or even cause a fire. To further avoid the above situation, in one embodiment of the present invention, the joint control device is also connected to the power supply of the server component. When the joint control device receives the target instruction, it turns off the power supply of the server component.

[0119] Specifically, when the joint control device receives a target command, it can also shut down the server components, thereby stopping power supply to the server components. Compared to running server components, even if the coolant corrodes the powered-off server components, it will not cause internal circuit breakage and further fire ignition, thereby further reducing losses caused by coolant leakage.

[0120] In practical applications, in order to prevent the leaked coolant from penetrating into the server components, the first component further includes a water absorbing component, which is wrapped around the first component and is used to absorb the coolant leaked from the first component.
