Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] According to one aspect of this application, a leak detection device 10 for a liquid-cooled server is provided. Figure 1A schematic diagram of a leak-proof detection device according to an embodiment of this application is shown. See also: Figure 1 The leak detection device 10 includes a support part 11, an absorption part 12, a guide pipe 13, a leak detection sensor 14, a liquid tank 15, and a controller 16.

[0028] According to the example embodiment, the bottom and sidewalls of the support portion 11 form a support space, and the bottom is also provided with a through hole. For example, the support portion 11 can be a tray with sidewalls. The support portion 11 can be fixedly disposed below the cold plate heat sink of the liquid-cooled server 20.

[0029] The absorption section 12 is made of a liquid-absorbing material and is disposed in the support space. The absorption section 12 is supported by the bottom and is used to house the liquid-cooled server 20. For example, the liquid-absorbing material can be a highly absorbent resin, a hydrophilic material, or a porous material. In the event of coolant leakage from the cold plate heat sink 21 of the liquid-cooled server 20, the absorption section 12 absorbs the coolant.

[0030] The inlet end of the guide tube 13 is connected to the absorption section 12 through a through hole. For example, the guide tube 13 can be made of materials such as polyethylene (PE), polypropylene, polyvinyl chloride, and composite materials. The guide tube 13 can lead the liquid absorbed by the absorption section 12 out from the bottom of the support section 11.

[0031] A leakage detection sensor 14 is installed in the flow guide pipe 13 to detect the liquid in the flow guide pipe 13 in real time and generate a liquid level signal. The liquid level signal can be a liquid signal generated by the leakage detection sensor 14 based on the liquid in the flow guide pipe 13. The leakage detection sensor 14 can detect the liquid in the flow guide pipe 13 in real time and generate a corresponding liquid level signal based on the volume of the liquid.

[0032] The liquid tank 15 is located below the support unit 11, and the inlet of the liquid tank 15 is connected to the outlet of the guide pipe 13. Liquid in the guide pipe 13 can flow into the liquid tank 15 for storage.

[0033] The controller 16 receives a liquid level signal and generates a first alarm signal when the liquid level signal exceeds a liquid level threshold. The liquid level threshold can be a preset upper limit value for the liquid (e.g., volume) in the guide pipe 13. The first alarm signal can be an alarm signal generated when the liquid level signal exceeds the upper limit value. When the liquid level signal exceeds the liquid level threshold, it indicates that a coolant leak has occurred. The first alarm signal can be an audible and visual alarm signal, etc.

[0034] Through the above embodiments, the leak detection device of this application includes a support unit, an absorption unit, a guide pipe, a leak detection sensor, a liquid tank, and a controller. The bottom and side walls of the support unit form a support space, and a through hole is also provided at the bottom; the absorption unit is made of adsorption material, is disposed in the support space, is supported by the bottom, and is used to place the liquid-cooled server; the input end of the guide pipe is connected to the absorption unit through the through hole; the leak detection sensor is disposed in the guide pipe, detects the liquid in the guide pipe in real time, and generates a liquid level signal; the liquid tank is disposed below the support unit, and the input end of the liquid tank is connected to the output end of the guide pipe; the controller receives the liquid level signal and generates a first alarm signal when the liquid level signal exceeds the liquid level threshold.

[0035] The technical solution of this application can improve the leakage protection effect by setting and detecting leakage prevention for a single liquid-cooled server, and can reduce the damage to the liquid-cooled server below the single liquid-cooled server in the event of leakage from a single liquid-cooled server.

[0036] Optionally, see Figure 1 The coolant flow channels of the liquid-cooled server 20 include an input flow channel 22 and an output flow channel 23.

[0037] The leak detection device 10 includes a pressure sensor 17. The pressure sensor 17 is located in the input channel 22, and detects the pressure in the input channel 22 in real time and generates a pressure signal. The pressure signal can be a signal generated by the pressure sensor 17 based on the liquid pressure value in the input channel 22. The pressure sensor 17 can detect the liquid pressure in the input channel 22 in real time and generate a corresponding pressure signal based on the liquid pressure.

[0038] The controller 16 receives a pressure signal and generates a second alarm signal if the pressure signal is below a pressure threshold. The pressure threshold can be a preset lower limit value of the liquid pressure in the input flow channel 22. The second alarm signal can be an alarm signal generated when the pressure signal is below the pressure threshold. When the pressure signal is below the pressure threshold, it indicates that the coolant has leaked, which may affect the heat exchange efficiency of the liquid-cooled server 20. The second alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0039] Through the above embodiments, the technical solution of this application detects the liquid pressure in the input flow channel by a pressure sensor, generates a corresponding pressure signal, and generates a second alarm signal when the pressure signal is lower than the pressure threshold.

[0040] Optionally, see Figure 1The leak detection device 10 includes a flow sensor 18. The flow sensor 18 is disposed in the input channel 22 and / or the output channel 23, and detects the liquid flow rate in the input channel 22 and / or the output channel 23 in real time, generating a flow signal. For example, the flow sensor 18 can be disposed solely in the input channel 22. The flow sensor 18 can be disposed solely in the output channel 23. The flow sensor 18 can also be disposed in both the input channel 22 and the output channel 23. The flow signal can be a signal generated by the flow sensor 18 based on the liquid flow rate value in the input channel 22 or the output channel 23. The flow sensor 18 can detect the liquid flow rate in the input channel 22 or the output channel 23 in real time and generate a corresponding flow signal based on the liquid flow rate.

[0041] The controller 16 receives a flow signal and generates a third alarm signal when the flow signal is below a flow threshold. The flow threshold can be a preset lower limit for the liquid flow rate in the input channel 22 or the output channel 23. The third alarm signal is an alarm signal generated when the flow signal is below the flow threshold. When the flow signal is below the flow threshold, it indicates that coolant has leaked or the filter is clogged, which may affect the heat exchange efficiency of the liquid-cooled server 20. The third alarm signal can be an audible or visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0042] Through the above embodiments, the technical solution of this application detects the flow rate of liquid in the input or output channel using a flow sensor, generates a corresponding flow signal, and generates a third alarm signal when the flow signal is lower than the flow threshold.

[0043] Optionally, see Figure 1 The leak detection device 10 includes a temperature sensor 19. The temperature sensor 19 is located in the output channel 23, detects the temperature of the output channel 23 in real time, and generates a temperature signal. The temperature signal is generated by the temperature sensor 19 based on the liquid temperature value in the output channel 23. The temperature sensor 19 can detect the liquid temperature in the output channel 23 in real time and generate a corresponding temperature signal based on the liquid temperature.

[0044] The controller 16 receives a temperature signal and generates a fourth alarm signal if the temperature signal is below a temperature threshold. The temperature threshold can be a preset lower limit value of the liquid temperature in the output flow channel 23. The fourth alarm signal can be an alarm signal generated when the temperature signal is below the temperature threshold. When the temperature signal is below the temperature threshold, it indicates that the circulating pump has malfunctioned or the flow rate has decreased, which may affect the heat exchange efficiency of the liquid-cooled server 20. The fourth alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0045] Through the above embodiments, the technical solution of this application detects the temperature of the liquid in the output channel using a temperature sensor, generates a corresponding temperature signal, and generates a fourth alarm signal when the temperature signal is lower than the temperature threshold.

[0046] Optionally, see Figure 1 The liquid-cooled server 20 is also equipped with a power supply unit 24. The power supply unit 24 supplies power to the liquid-cooled server 20.

[0047] The leak detection device 10 also includes a current sensor ( Figure 1 (Not shown in the image). A current sensor is installed on the input power phase line of the power supply unit 24 to detect the current of the input power phase line in real time and generate a current signal. The current signal is the signal that the current sensor should generate based on the current value of the input power phase line of the power supply unit 24. The current sensor can detect the current value of the input power phase line of the power supply unit 24 (i.e., the operating current value of the liquid-cooled server 20) in real time and generate a corresponding current signal based on the current value.

[0048] The controller 16 receives a current signal and generates a fifth alarm signal if the current signal exceeds a current threshold. The current threshold can be a preset upper limit for the current value of the input power phase line of the power supply unit 24. The fifth alarm signal can be an alarm signal generated when the current signal exceeds the current threshold. A current signal exceeding the current threshold indicates low heat exchange efficiency of the liquid-cooled server 20, which may lead to overcurrent protection or shutdown of the liquid-cooled server 20. The fifth alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0049] Through the above embodiments, the technical solution of this application detects the current of the input power phase line of the power supply unit through a current sensor, generates a corresponding current signal, and generates a fifth alarm signal when the current signal is higher than the current threshold.

[0050] Optionally, the controller generates an alarm signal to send an alarm signal to the user terminal if any two of the following signals are generated: a first alarm signal, a second alarm signal, a third alarm signal, a fourth alarm signal, and a fifth alarm signal.

[0051] According to the example embodiment, liquid level signal, pressure signal, flow rate signal, temperature signal, or current signal can be used as one of the conditions to assist in determining whether a liquid-cooled server has leaked. When any two of the first, second, third, fourth, and fifth alarm signals are generated, the controller can determine that a leak has occurred in the liquid-cooled server, generate an alarm signal, and send an alarm signal to the user terminal.

[0052] According to one aspect of this application, a leak detection system for liquid-cooled servers is provided. The leak detection system includes at least two leak detection devices as described above. The system can remotely manage the operating status parameters (e.g., liquid level signal, pressure signal, flow signal, temperature signal, or current signal) of several to dozens of leak detection devices installed in different locations, thereby enabling monitoring of the distributed leak detection devices for easier operation by maintenance personnel.

[0053] According to one aspect of this application, a leak-proof detection method for a liquid-cooled server is provided. The leak-proof detection method 3000 can be executed by the leak-proof detection device described above. Specifically, the leak-proof detection method 3000 can be executed by the controller described above. The structure of the leak-proof detection device has been described above and will not be repeated here.

[0054] Figure 2 This diagram illustrates a flow chart of a leak-proof liquid detection method 3000 according to an embodiment of this application. See also: Figure 2 The leak detection method 3000 includes steps S310 to S350. Steps S310 to S350 can be executed simultaneously.

[0055] In step S310, the controller generates a first alarm signal when the liquid level signal received from the leakage detection sensor exceeds the liquid level threshold.

[0056] According to the example embodiment, a leak detection sensor is installed in the flow guide tube to detect the liquid in the tube in real time and generate a liquid level signal. The liquid level signal can be a liquid signal generated by the leak detection sensor based on the liquid volume in the flow guide tube. The leak detection sensor can detect the liquid in the flow guide tube in real time and generate a corresponding liquid level signal based on the liquid volume.

[0057] The liquid level threshold can be a preset upper limit for the liquid (e.g., volume) in the guide pipe. The first alarm signal can be an alarm signal generated when the liquid level exceeds the upper limit. When the liquid level exceeds the liquid level threshold, it indicates that coolant leakage has occurred. The first alarm signal can be an audible and visual alarm signal, etc.

[0058] In step S320, the controller generates a second alarm signal when the pressure signal received from the pressure sensor is lower than the pressure threshold.

[0059] According to an example embodiment, the coolant flow channel of the liquid-cooled server includes an input channel and an output channel. A pressure sensor is disposed in the input channel to detect the pressure in the input channel in real time and generate a pressure signal. The pressure signal can be a signal generated by the pressure sensor based on the liquid pressure value in the input channel. The pressure sensor can detect the liquid pressure in the input channel in real time and generate a corresponding pressure signal based on the liquid pressure.

[0060] The pressure threshold can be a preset lower limit value for the liquid pressure in the input channel. The second alarm signal can be an alarm signal generated when the pressure signal is lower than the pressure threshold. When the pressure signal is lower than the pressure threshold, it indicates that the coolant has leaked, which may affect the heat exchange efficiency of the liquid-cooled server. The second alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0061] In step S330, the controller generates a third alarm signal when the flow signal received from the flow sensor is lower than the flow threshold.

[0062] According to an example embodiment, a flow sensor is disposed in the input channel and / or output channel to detect the liquid flow rate in the input channel and / or output channel in real time and generate a flow signal. For example, the flow sensor can be disposed solely in the input channel. The flow sensor can be disposed solely in the output channel. The flow sensor can also be disposed in both the input channel and the output channel. The flow signal can be a signal generated by the flow sensor based on the liquid flow rate value in the input channel. The flow sensor can detect the liquid flow rate in the input channel or output channel in real time and generate a corresponding flow signal based on the liquid flow rate.

[0063] The flow threshold can be a preset lower limit for the liquid flow rate in the input channel. The third alarm signal is generated when the flow rate falls below the flow threshold. A flow rate below the threshold indicates a coolant leak or filter blockage, potentially affecting the heat exchange efficiency of the liquid-cooled server. The third alarm signal can be an audible or visual alarm to alert maintenance personnel for timely intervention.

[0064] In step S340, the controller generates a fourth alarm signal when the temperature signal received from the temperature sensor is lower than the temperature threshold.

[0065] According to the example embodiment, a temperature sensor is disposed in the output flow channel to detect the temperature of the output flow channel in real time and generate a temperature signal. The temperature signal is a signal generated by the temperature sensor based on the liquid temperature value in the output flow channel. The temperature sensor can detect the liquid temperature in the output flow channel in real time and generate a corresponding temperature signal based on the liquid temperature.

[0066] The temperature threshold can be a preset lower limit for the liquid temperature in the output channel. The fourth alarm signal is an alarm signal generated when the temperature signal is lower than the temperature threshold. When the temperature signal is lower than the temperature threshold, it indicates that the circulating pump has malfunctioned or the flow rate has decreased, which may affect the heat exchange efficiency of the liquid-cooled server. The fourth alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation promptly.

[0067] In step S350, the controller generates a fifth alarm signal when the current signal received from the current sensor is higher than the current threshold.

[0068] According to the example embodiment, the liquid-cooled server is also configured with a power supply unit. The power supply unit supplies power to the liquid-cooled server. A current sensor is installed on the input power phase line of the power supply unit to detect the current in the input power phase line in real time and generate a current signal. The current signal is the signal that the current sensor should generate based on the current value of the power supply unit. The current sensor can detect the current value of the input power phase line of the power supply unit (i.e., the operating current value of the liquid-cooled server) in real time and generate a corresponding current signal based on the current value.

[0069] The current threshold can be a preset upper limit for the current value of the input power phase line of the power supply unit. The fifth alarm signal can be an alarm signal generated when the current signal exceeds the current threshold. When the current signal exceeds the current threshold, it indicates that the heat exchange efficiency of the liquid-cooled server is low, which may lead to overcurrent protection or shutdown of the liquid-cooled server. The fifth alarm signal can be an audible and visual alarm signal, etc., to remind maintenance personnel to handle the situation in a timely manner.

[0070] Through the above embodiments, the technical solution of this application can generate a first alarm signal when the liquid level signal exceeds a liquid level threshold. The technical solution of this application can generate a second alarm signal when the pressure signal is below a pressure threshold. The technical solution of this application can generate a third alarm signal when the flow rate signal is below a flow rate threshold. The technical solution of this application can generate a fourth alarm signal when the temperature signal is below a temperature threshold. The technical solution of this application can generate a fifth alarm signal when the current signal is above a current threshold.

[0071] The technical solution of this application can improve the leakage protection effect by setting and detecting leakage prevention for a single liquid-cooled server, and can reduce the damage to the liquid-cooled server below the single liquid-cooled server in the event of leakage from a single liquid-cooled server.

[0072] Optionally, see Figure 3 After step S350, the leak detection method 3000 further includes step S360.

[0073] In step S360, if any two of the first alarm signal, second alarm signal, third alarm signal, fourth alarm signal and fifth alarm signal are generated, the controller generates an alarm signal to send an alarm signal to the user terminal.

[0074] According to the example embodiment, liquid level signal, pressure signal, flow rate signal, temperature signal, or current signal can be used as one of the conditions to assist in determining whether a liquid-cooled server has leaked. When any two of the first, second, third, fourth, and fifth alarm signals are generated, the controller can determine that a leak has occurred in the liquid-cooled server, generate an alarm signal, and send an alarm signal to the user terminal.

[0075] According to another aspect of this application, this application also provides a non-volatile computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, is capable of implementing the leakage detection method for liquid-cooled servers as described above.
