Description

Technical Field

[0001] This application relates to the field of leakage detection technology, and in particular to a server rack anti-overflow system, method, and server rack. Background Technology

[0002] With the rapid advancement of information technology, communication equipment is developing towards high integration, and servers, as core components of information processing, are seeing a continuous increase in power density. While this trend has brought about a significant improvement in computing power, it has also brought about a problem that cannot be ignored—heat dissipation.

[0003] To solve the heat dissipation problem, the industry has begun to widely adopt liquid cooling technology as a new solution for server heat dissipation. However, this also brings the risk of liquid leakage. Once the liquid in the liquid cooling system leaks, it will not only cause direct damage to the server at the leak point, but may also penetrate into other servers or data center equipment through the complex wiring and other structures inside the rack, posing a serious threat to the stable operation of the entire data center.

[0004] Among the technologies related to addressing liquid cooling leaks, some servers employ liquid cooling modules with leak detection capabilities. These modules issue alarms when a leak is detected, but their functionality is limited, lacking the ability to accurately detect and handle leaks. Furthermore, while some servers are equipped with leak-proof structures to collect leaked liquid, these structures are often simply designed, leaving the risk of leaked liquid spreading to other areas or equipment. Therefore, effectively detecting and handling liquid cooling leaks has become a pressing problem that needs to be solved. Summary of the Invention

[0005] This application provides a server rack anti-overflow system, method, and server rack to solve the problem that the leakage detection methods and leakage handling configurations in related technologies are simple, cannot accurately determine the leakage situation and handle the leakage location, and are prone to causing the server in the data center to malfunction due to the inability to detect and handle leakage in a timely manner. This application can accurately determine the leakage situation and handle leakage, ensuring the normal operation of the server.

[0006] The first aspect of this application provides a server rack anti-spillage system, including:

[0007] The first detection module is used to detect whether there is liquid leakage in the server rack;

[0008] The second detection module is used to detect the amount of liquid leakage at the bottom of the server rack, and generate a side liquid level signal when the liquid level in the server rack meets the preset signal generation conditions.

[0009] Drive assembly for extending the extendable base plate at the bottom of the server rack;

[0010] The control module is used to control the drive assembly to stretch the stretchable base plate according to the bottom leakage amount and / or the side liquid level signal in the event of liquid leakage in the server rack.

[0011] The cooling capacity distribution module is used to extract the leaking liquid from the server rack based on the side liquid level signal.

[0012] Through the above technical solution, when the first detection module detects a liquid leak in the server rack, the second detection module detects the amount of liquid leaking from the bottom of the server rack. When the liquid level reaches a preset condition, a side liquid level signal is generated, causing the control module to control the drive component to stretch the stretchable base plate. The cooling distribution module then extracts the leaking liquid from the server rack based on the side liquid level signal, thereby quickly removing the leaking liquid from the server rack and effectively preventing the leak from spreading further to other areas inside the rack. This not only reduces the damage to the server caused by the leak but also keeps the inside of the rack clean and dry, providing a good environment for the stable operation of the server.

[0013] Optionally, the second detection module includes:

[0014] The first detection unit is used to detect the amount of liquid leakage at the bottom of the server rack; the second detection unit is used to generate a side liquid level signal when the liquid level in the server rack reaches the height of the position of the second detection unit.

[0015] The above technical solution allows for timely detection of initial liquid leaks by using the first detection unit to detect the amount of liquid leakage at the bottom of the server rack. The second detection unit generates a side liquid level signal when the liquid level in the rack rises to its position, which can more accurately reflect the liquid leakage situation inside the rack and improve the accuracy and sensitivity of monitoring.

[0016] Optionally, the control module includes:

[0017] The first control unit is configured to, in the event of a liquid leak in the server rack, if the amount of liquid leakage at the bottom exceeds a preset amount, control the drive assembly to stretch the stretchable base plate to seal the front and rear windows of the server rack.

[0018] And / or, a second control unit, configured to, in the event of a liquid leak in the server rack, if the second detection unit generates the side liquid level signal, control the drive assembly to stretch the stretchable base plate according to a preset stretching step size until the second detection unit reaches a preset height.

[0019] Through the above technical solution, the first control unit and the second control unit set different leakage protection strategies according to different leakage situations, so that the system can flexibly adjust the response measures according to the actual situation, which not only avoids the waste of resources caused by over-response, but also ensures the effectiveness of the response measures.

[0020] Optionally, the second detection unit is disposed on the connector between the drive assembly and the stretchable base plate, so that when the second control unit controls the drive assembly to stretch the stretchable base plate according to the preset stretching step, the second detection unit moves along with the stretching.

[0021] By combining the second detection unit with the drive assembly and the stretchable base plate, the overall structure of the system can be simplified, which not only reduces the number and complexity of parts, but also helps to reduce the installation and maintenance costs of the system.

[0022] Optionally, the cooling capacity distribution module is further configured to: determine the valve switching angle of the liquid supply pipeline of the server rack according to the current height of the second detection unit when the total stretching step of the second detection unit is greater than the preset step, and perform liquid supply and return control according to the valve switching angle.

[0023] With the above technical solution, when a liquid leak is detected and causes the second detection unit to stretch beyond the preset step length, the system can dynamically adjust the supply of coolant according to the actual leakage situation and the liquid level change inside the cabinet, ensuring that the server operates within a safe temperature range and avoiding over-cooling or under-cooling.

[0024] Optionally, the aforementioned server rack spill prevention system also includes:

[0025] A flow guiding module, corresponding to each server in the server rack, is used to guide the leaking liquid to the bottom of the server rack when there is leakage in the heat exchange components of the server rack.

[0026] With the above technical solution, since each server has a corresponding flow guiding module, when leakage occurs, the leakage will be quickly guided to the bottom of the rack, enabling maintenance personnel to locate the source of leakage more quickly and take timely and effective countermeasures. It also prevents the leakage from directly contacting the server hardware, thereby reducing the potential damage to the server.

[0027] Optionally, the control module is further configured to determine the server to be powered off based on the height of the location of the second detection unit, and to perform a power-off operation on the server to be powered off.

[0028] By employing the above technical solution, the server to be powered off is determined based on the position and height of the second detection unit, and the power-off operation is executed in a timely manner. This effectively prevents and controls liquid leakage inside the server cabinet, thus protecting server safety.

[0029] Optionally, the control module is also used to control the power outage of the server corresponding to the server rack in the event of a liquid leak in the server rack.

[0030] The above technical solution enables the control module to power off all servers when liquid leakage occurs in the server rack, effectively preventing and controlling liquid leakage inside the server rack and protecting server safety.

[0031] A second aspect of this application provides a server rack that includes the aforementioned server rack anti-overflow system.

[0032] A third aspect of this application provides a method for preventing liquid spillage in a server rack, employing the aforementioned server rack liquid spillage prevention system, wherein the method includes the following steps:

[0033] Check the server rack for liquid leaks;

[0034] The system detects the amount of liquid leakage at the bottom of the server rack and generates a side liquid level signal when the liquid level in the server rack meets the preset signal generation conditions.

[0035] In the event of a liquid leak in the server rack, the drive assembly is controlled to stretch the stretchable base plate based on the amount of liquid leaked from the bottom and / or the side liquid level signal, and the leaking liquid in the server rack is extracted based on the side liquid level signal.

[0036] In the above embodiment, a first detection module detects whether there is liquid leakage in the server rack, a second detection module detects the amount of liquid leakage at the bottom of the server rack, and generates a side liquid level signal when the liquid level in the server rack meets the preset signal generation conditions. A drive component stretches the stretchable base plate at the bottom of the server rack, and a control module, in the event of liquid leakage in the server rack, controls the drive component to stretch the stretchable base plate based on the amount of liquid leakage at the bottom and / or the side liquid level signal. A cooling distribution module extracts the leaking liquid from the server rack based on the side liquid level signal. This solves the problem that related technologies have simple leakage detection methods and simple leakage handling configurations, which cannot accurately determine the leakage situation and the location of the leak, easily leading to server malfunctions due to the inability to detect and handle leaks in a timely manner. This method can accurately determine the leakage situation and handle the location of the leak, avoiding risks to servers caused by leaks, while ensuring that servers in other locations can operate normally without being affected by the leaking server.

[0037] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0044] Figure 6 This is a flowchart of a server rack anti-overflow method according to an embodiment of this application. Detailed Implementation

[0045] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0046] The following description, with reference to the accompanying drawings, outlines an embodiment of a server rack anti-overflow system, method, and server rack. Addressing the limitations of existing leak detection methods and simple leak handling configurations in the background art, which cannot accurately determine the extent and location of leaks, potentially leading to server malfunctions due to delayed detection and handling, this application provides a server rack anti-overflow system. In this system, when a first detection module detects a liquid leak in the server rack, a second detection module detects the amount of leakage at the bottom of the rack. When the liquid level reaches a preset threshold, a side liquid level signal is generated. This triggers a control module that extends the extendable base plate, and a cooling distribution module extracts the leaked liquid from the server rack based on the side liquid level signal. This rapid extraction effectively prevents the leak from spreading further into other areas of the rack, reducing damage to the server and maintaining a clean and dry environment inside the rack, thus providing a favorable environment for stable server operation.

[0047] Specifically, Figure 1 This is a block diagram of a server rack anti-overflow system provided in an embodiment of this application.

[0048] like Figure 1 As shown, the server rack anti-overflow system 10 includes: a first detection module 100, a second detection module 200, a drive component 300, a control module 400, and a cooling capacity distribution module 500.

[0049] The system includes a first detection module 100 for detecting whether there is liquid leakage in the server rack; a second detection module 200 for detecting the amount of liquid leakage at the bottom of the server rack and generating a side liquid level signal when the liquid level in the server rack meets the preset signal generation conditions; a drive component 300 for stretching the stretchable base plate 700 at the bottom of the server rack; a control module 400 for controlling the drive component 300 to stretch the stretchable base plate 700 according to the amount of liquid leakage at the bottom and / or the side liquid level signal when there is liquid leakage in the server rack; and a cooling capacity distribution module 500 for extracting the leaking liquid from the server rack according to the side liquid level signal.

[0050] The first detection module 100 can be a leak detector, and the second detection module 200 can include two liquid level detectors, namely a low liquid level detector 401 and a high liquid level detector 402. The drive component 300 can be a motor. The leak detectors are installed on the heat exchange structure of the server rack. A stretchable base plate 700 and the low liquid level detector 401 can be installed at the bottom of the server rack, and the high liquid level detector 402 can be installed on the side of the server rack. The leak detectors can be used to detect whether there is a liquid leak in the server rack. The low liquid level detector 401 is used to detect the amount of liquid leakage at the bottom of the server rack, the motor is located at the top of the server rack, and the high liquid level detector 402 is used to detect the liquid level height of the server rack. The structure of the server rack anti-overflow system is as follows. Figure 2 As shown, the side view of the server rack anti-overflow system is as follows: Figure 3 As shown in (a), the top view of the server rack anti-overflow system is as follows. Figure 3 As shown in (b), the preset signal generation condition is that there is bottom leakage in the server rack, but the bottom leakage does not reach the top of the server rack.

[0051] It should be noted that the structural diagram of the server rack anti-overflow system in this application embodiment is merely an exemplary drawing.

[0052] Understandably, the first detection module 100 repeatedly detects whether there is liquid leakage in the server rack according to a preset detection cycle. In this embodiment, the preset detection cycle can be set to 2 to 5 seconds. Each detection signal is fed back to the control module 400. If the detection signal from the first detection module 100 is a leakage signal, the second detection module 200 detects the amount of liquid leakage at the bottom of the server rack. When the liquid level in the server rack meets the preset signal generation conditions, a side liquid level signal is generated. The control module 400 performs leakage discharge and server control protection based on the amount of liquid leakage at the bottom, or based on the side liquid level signal, or based on both the amount of liquid leakage at the bottom and the side liquid level signal. If the first detection module 100 does not detect leakage, the control module 400 controls each server to maintain its current state and does not perform any action.

[0053] Therefore, when the first detection module detects a liquid leak in the server rack, the second detection module detects the amount of liquid leaking from the bottom of the server rack. When the liquid level reaches a preset condition, a side liquid level signal is generated, causing the control module to control the drive component to stretch the stretchable base plate. The cooling distribution module then extracts the leaking liquid from the server rack based on the side liquid level signal, thus quickly removing the leaking liquid from the server rack and effectively preventing the leak from spreading further to other areas inside the rack. This not only reduces the damage to the server caused by the leak but also keeps the inside of the rack clean and dry, providing a good environment for the stable operation of the server.

[0054] Optionally, in some embodiments, the second detection module 200 includes: a first detection unit for detecting the amount of liquid leakage at the bottom of the server rack; and a second detection unit for generating a side liquid level signal when the liquid level in the server rack reaches the height of the second detection unit.

[0055] It is understandable that if the second detection module 200 detects the bottom leakage, and the second detection unit detects that the leakage has reached the height of the liquid level in the server rack, which is the height of the second detection unit, a side liquid level signal will be generated.

[0056] Therefore, by detecting the amount of liquid leakage at the bottom of the server rack through the first detection unit, the initial liquid leakage can be detected in time. By using the second detection unit to generate a side liquid level signal when the liquid level in the rack rises to its position, the leakage situation inside the rack can be reflected more accurately, improving the accuracy and sensitivity of monitoring.

[0057] Optionally, in some embodiments, the control module 400 includes: a first control unit and / or a second control unit. The first control unit is configured to, in the event of a liquid leak in the server rack, if the leakage at the bottom exceeds a preset leakage amount, control the drive assembly 300 to stretch the stretchable base plate 700 to seal the front and rear windows of the server rack; and / or, the second control unit is configured to, in the event of a liquid leak in the server rack, if a second detection unit generates a side liquid level signal, control the drive assembly 300 to stretch the stretchable base plate 700 by a preset stretching step size until the second detection unit reaches a preset height.

[0058] The first detection unit is used to detect the amount of liquid leakage at the bottom of the server rack, such as... Figure 2 As shown, the first detection unit can be a low liquid level detector 401, and the second detection unit is a detection unit used to generate a side liquid level signal, such as... Figure 2As shown, the second detection unit can be a high liquid level detector 402; the preset height is the top of the server rack; the preset leakage amount can be a threshold set by the user, a threshold obtained through a limited number of experiments, or a threshold obtained through a limited number of computer simulations, and no specific limitation is made here.

[0059] Specifically, if the second detection module 200 detects the bottom leakage amount, and the first detection unit detects that the bottom leakage amount is greater than the preset leakage amount, the first control unit controls the drive component 300 to stretch the stretchable base plate 700 and close the front and rear windows of the server rack. The liquid is discharged from the server through the drain port via the corresponding flow guide module 600 and enters the server rack. The bottom of the server rack is sealed to prevent liquid from leaking out of the rack.

[0060] If the second detection module 200 detects bottom leakage, and the second detection unit detects leakage until the liquid level in the server rack reaches the height of the second detection unit, a side liquid level signal is generated. At this time, the second control unit controls the drive assembly 300 to stretch the stretchable base plate 700 according to a preset stretching step. The second detection unit moves along with the stretchable base plate 700 until the second detection unit reaches the top of the server rack, at which point the drive assembly 300 stops rotating. Simultaneously, when the second detection unit generates the side liquid level signal, the replenishment pump of the cooling distribution module 500 starts. The liquid in the server rack is filtered and pumped into the supply pipeline, thus achieving liquid recycling. When the flow meter reading in the cooling distribution module 500 approaches zero and the liquid level detector at the bottom of the server rack does not detect bottom leakage, the replenishment pump stops.

[0061] For example, if the high liquid level detector 402 generates a side liquid level signal, the second control unit controls the motor to stretch the stretchable base plate 700 in 1U increments. The high liquid level detector 402 follows the stretchable base plate 700 and moves in 1U increments until the high liquid level detector 402 reaches the top of the server rack. At the same time, the replenishment pump starts, and the liquid in the server rack is filtered and pumped into the cooling capacity distribution module 500, so that the liquid is recycled. When the reading of the flow meter in the cooling capacity distribution module 500 is close to zero and the liquid level detector at the bottom of the server rack does not detect bottom leakage, the replenishment pump stops. When the high liquid level detector 402 does not generate a side liquid level signal, the motor stops and does not stretch.

[0062] Therefore, the first control unit and the second control unit set different leakage protection strategies according to different leakage situations, so that the system can flexibly adjust the response measures according to the actual situation, which not only avoids the waste of resources caused by over-response, but also ensures the effectiveness of the response measures.

[0063] Optionally, in some embodiments, the second detection unit is disposed on the connector between the drive assembly 300 and the stretchable base plate 700, so that when the second control unit controls the drive assembly 300 to stretch the stretchable base plate 700 according to a preset stretching step, the second detection unit moves along with the stretching.

[0064] It should be noted that in the server field, the default stretch step is 1U. 1U is a unit of height for rack-mount servers. 1U equals 1.75 inches, or about 4.445 centimeters. The "default stretch step" here usually refers to the height space occupied by the server in the rack, that is, the height of a 1U server is 1.75 inches.

[0065] Understandably, the high liquid level detector is mounted on the connector between the motor and the stretchable base plate 700, and is used to move the high liquid level detector when the stretchable base plate 700 is stretched.

[0066] Therefore, by combining the second detection unit with the drive assembly and the stretchable base plate, the overall structure of the system can be simplified, which not only reduces the number and complexity of parts, but also helps to reduce the installation and maintenance costs of the system.

[0067] Optionally, in some embodiments, the server rack anti-overflow system 10 described above further includes a diversion module 600. The diversion module 600 is configured corresponding to each server in the server rack, and is used to divert leaked liquid to the bottom of the server rack when there is leakage in the heat exchange components of the server rack.

[0068] Understandably, each server in the server rack is equipped with a drainage module 600, which is used to drain the leaked liquid to the bottom of the server rack through the drain port when there is leakage in the heat exchange components of the server rack.

[0069] As one embodiment, the flow guiding module 600 can be designed with a structure having guiding grooves or guiding pipes. These grooves or pipes can guide the leaked liquid to flow along a specific path. In terms of material, the flow guiding module 600 is typically made of corrosion-resistant and wear-resistant materials to ensure its long-term reliability and stability. When a heat exchange component (such as coolant pipes, radiators, etc.) leaks inside the server rack, the leaked liquid will first come into contact with the flow guiding module 600, which will quickly guide the leaked liquid to the bottom of the server rack through its guiding grooves or guiding pipes.

[0070] Therefore, since each server has a corresponding flow guiding module, when leakage occurs, the leakage will be quickly guided to the bottom of the rack, allowing maintenance personnel to locate the source of leakage more quickly and take timely and effective countermeasures. It also prevents the leakage from directly contacting the server hardware, thereby reducing the potential damage to the server.

[0071] Optionally, in some embodiments, the cold energy distribution module 500 is further configured to: determine the valve switching angle of the liquid supply pipeline of the server rack according to the current height of the second detection unit when the total stretching step of the second detection unit is greater than the preset step, and perform liquid supply and return control according to the valve switching angle.

[0072] The preset step size can be a threshold set by the user, a threshold obtained through a limited number of experiments, or a threshold obtained through a limited number of computer simulations. In this embodiment, the preset step size is 2U.

[0073] Specifically, when the second detection unit moves with the stretchable base plate 700, if the total stretching step of the second detection unit is greater than the preset step, the cold energy distribution module 500 controls the supply and return of liquid according to the valve opening and closing angle of the liquid supply pipeline, specifically based on the current height of the second detection unit.

[0074] For example, when the total extension step of the high liquid level detector 402 is less than or equal to 2U, the valve opening angle remains unchanged. When the total extension step of the high liquid level detector 402 is greater than 2U, the cooling capacity distribution module 500 determines the valve opening angle of the liquid supply line of the server rack based on the current height of the high liquid level detector 402. When the total extension step of the high liquid level detector 402 exceeds 40U, the valve 800 of the liquid supply line is closed. The specific valve opening angle adjustment formula is as follows:

[0075] n= (1 - Current height of the high liquid level detector / Height of the server rack).

[0076] It should be noted that the current height of the high liquid level detector 402 and the height of the server rack are converted according to U-numbers.

[0077] Therefore, when a liquid leak is detected and causes the second detection unit to stretch beyond the preset step size, the system can dynamically adjust the supply of coolant according to the actual leak situation and the changes in the liquid level inside the cabinet, ensuring that the server operates within a safe temperature range and avoiding over-cooling or under-cooling.

[0078] Optionally, in some embodiments, the control module 400 is further configured to determine the server to be powered off based on the height of the location of the second detection unit, and to perform a power-off operation on the server to be powered off.

[0079] Among them, the server to be powered off is the server that is about to be powered off.

[0080] It is understandable that when the second detection unit generates a side liquid level signal, the second control unit controls the drive assembly 300 to stretch the stretchable base plate 700 according to a preset stretching step size, and the second detection unit moves along with the stretchable base plate 700, the power-off server at the corresponding position of the second detection unit is powered off.

[0081] Therefore, by determining the server to be powered off based on the position and height of the second detection unit and promptly executing the power-off operation, effective prevention and control of liquid leakage inside the server rack are achieved, thus protecting server safety.

[0082] Optionally, in some embodiments, the control module 400 is also used to control the power off of the server corresponding to the server rack in the event of a liquid leak in the server rack.

[0083] Understandably, if there is a liquid leak in the server rack, the control module 400 will control the corresponding server to cut off power.

[0084] Therefore, by controlling the module to cut off power to all servers when there is a liquid leak in the server rack, the liquid leak inside the server rack can be effectively prevented and controlled, thus protecting the server safety.

[0085] To enable those skilled in the art to further understand the server rack anti-overflow system of the embodiments of this application, the following is combined with Figure 4 and Figure 5 To elaborate in detail.

[0086] like Figure 4 As shown, Figure 4 This is a simplified diagram of a server rack anti-overflow system. Specifically, when the first detection module 100 and the second detection module 200 detect leakage in the server rack, the control module performs drainage protection and server protection control.

[0087] In step S501, the server rack anti-overflow system is activated.

[0088] In step S502, the leakage detector on the server base plate performs leakage detection on the server rack three times according to the preset detection cycle. Each detection signal is fed back to the control module. If the leakage detector detects a leakage signal, step S503 is executed. If the leakage detector does not detect a leakage signal, the system controls the server to maintain the current state and does not perform any action.

[0089] In step S503, server protection and leakage control are initiated.

[0090] While performing step S504, step S505 is also performed.

[0091] In step S504, if the leakage detector detects leakage in the server rack, and the low liquid level detector at the bottom of the server base plate detects that the leakage amount at the bottom is greater than the preset leakage amount, the liquid is discharged from the server through the drain port via the corresponding flow guide module of the server and enters the server rack. The bottom of the server rack is sealed to prevent the liquid from leaking out of the rack. At the same time, step S506 is executed.

[0092] In step S505, the server is powered off.

[0093] In step S506, the first control unit controls the motor to stretch the stretchable base plate, sealing the front and rear windows of the server cabinet. The motor stops, and after the server is powered on again, the stretchable base plate resets.

[0094] In step S507, a low liquid level sensor inside the server rack detects the amount of liquid leakage at the bottom.

[0095] In step S508, if the high liquid level detector generates a side liquid level signal, the second control unit controls the motor to stretch the stretchable base plate by 1U. The high liquid level detector moves with the stretchable base plate, the replenishment pump of the cold energy distribution module starts, and the liquid in the server rack is filtered through the filter and pumped into the liquid supply pipeline, so that the liquid is recycled. While executing step S508, step S509 or step S511 is executed.

[0096] In step S509, if the high liquid level sensor continues to generate a side liquid level signal, the motor continues to stretch the stretchable plate until the high liquid level sensor reaches the top of the cabinet, and the motor stops. At the same time as step S509, step S510 is executed.

[0097] In step S510, the server at the corresponding location is powered down when the high liquid level detector moves.

[0098] In step S511, if the high liquid level sensor does not generate a side liquid level signal, the motor stops, the high liquid level sensor moves 1U, and the control valve of the liquid supply pipeline does not operate.

[0099] In step S512, if the high liquid level sensor moves 2U, the control valve starts to operate, specifically step S513.

[0100] In step S513, the valve opening angle of the liquid supply pipeline of the server rack is determined according to the current height of the high liquid level detector, and the liquid supply and return are controlled according to the valve opening angle until the high liquid level detector reaches the top of the server rack, at which point the valve closes and the valve opens after the server is powered on again.

[0101] According to the server rack anti-overflow system proposed in this application, when a liquid leak is detected in the server rack by the first detection module, the leakage amount at the bottom of the server rack is detected by the second detection module. When the liquid level reaches a preset condition, a side liquid level signal is generated, causing the control module to control the drive component to stretch the stretchable base plate. The cooling distribution module then extracts the leaking liquid from the server rack based on the side liquid level signal. This solves the problems of simple leak detection methods and simple leak handling configurations in related technologies, which cannot accurately determine the leak situation and location, easily leading to server malfunctions due to the inability to detect and handle leaks in a timely manner. The system can accurately determine the leak situation and location, avoiding risks to servers caused by leaks, while ensuring that servers in other locations can operate normally without being affected by the leak.

[0102] Next, referring to the accompanying drawings, a method for preventing liquid spillage in server racks according to embodiments of this application is described.

[0103] Figure 6 This is a block diagram illustrating a method for preventing liquid spillage in server racks according to an embodiment of this application.

[0104] like Figure 6 As shown, the method for preventing liquid spillage in server racks includes the following steps:

[0105] In step S601, the presence of liquid leakage in the server rack is detected.

[0106] In step S602, the amount of liquid leakage at the bottom of the server rack is detected, and a side liquid level signal is generated when the liquid level in the server rack meets the preset signal generation conditions.

[0107] In step S603, if there is a liquid leak in the server rack, the drive assembly is controlled to stretch the stretchable base plate according to the bottom leakage amount and / or the side liquid level signal, and the leaking liquid in the server rack is extracted according to the side liquid level signal.

[0108] It should be noted that the foregoing explanation of the server rack anti-overflow system embodiment also applies to the server rack anti-overflow method of this embodiment, and will not be repeated here.

[0109] The server rack anti-overflow method proposed in this application detects whether there is liquid leakage in the server rack, detects the amount of liquid leakage at the bottom of the server rack, and generates a side liquid level signal when the liquid level in the server rack meets the preset signal generation conditions. In the event of liquid leakage in the server rack, the drive component is controlled to stretch the stretchable base plate based on the amount of liquid leakage at the bottom and / or the side liquid level signal, and the leaking liquid in the server rack is extracted based on the side liquid level signal. This solves the problem that related technologies have simple leakage detection methods and simple leakage handling configurations, which cannot accurately determine the leakage situation and handle the liquid at the leakage location. This can easily lead to the inability to detect and handle leakage in a timely manner, causing the servers in the data center to malfunction. The method can accurately determine the leakage situation and handle the liquid at the leakage location, avoiding risks to servers caused by leakage, while ensuring that servers in other locations can work normally and are not affected by the server at the leakage location.

[0110] Furthermore, this application also proposes a server rack that includes the aforementioned server rack anti-overflow system.

[0111] According to the server rack proposed in the embodiments of this application, the above-mentioned server rack anti-overflow system solves the problem that the leakage detection method in the related technology is simple and the leakage handling configuration structure is simple. It is impossible to accurately judge the leakage situation and handle the liquid at the leakage location. This can easily cause the server in the data center to malfunction due to the inability to detect and handle the leakage in time. The system can accurately judge the leakage situation and handle the liquid at the leakage location, avoid the risk of leakage to the server, and ensure that the servers in other locations can work normally without being affected by the server at the leakage location.
