Description

Technical Field

[0001] The present application relates to the technical field of liquid leakage detection, and in particular to a server cabinet anti-liquid overflow system, method and server cabinet. Background Art

[0002] With the rapid advancement of information technology, communication equipment is moving towards a highly integrated direction. As the core component of information processing, the configuration power density of servers is also continuing to rise. Although this trend has brought about a significant increase in computing power, it has also brought about a problem that cannot be ignored - heat dissipation.

[0003] In order to solve the heat dissipation problem, the industry has begun to widely adopt liquid cooling technology as a new solution for server heat dissipation, but it 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 where the leakage point is located, but may also penetrate into other servers or computer room equipment through the complex wiring and other structures inside the cabinet, posing a serious threat to the stable operation of the entire computer room.

[0004] In the related technologies for dealing with liquid cooling leakage problems, some servers use liquid cooling modules with leakage detection functions. When a liquid leak is detected, an alarm is issued, but these leakage detection systems have a single function and lack the ability to accurately detect and handle leaks. In addition, although some servers are equipped with leakage collection structures to collect leaked liquids, these structures are often simple in design and there is still a risk of leaked liquid spreading to other areas or equipment. Therefore, how to effectively detect and handle liquid cooling leakage problems has become a difficult problem that needs to be solved urgently. Summary of the invention

[0005] The present application provides a server cabinet anti-overflow system, method and server cabinet to solve the problem that the leakage detection method in the related art is simple, and the leakage processing configuration structure is simple, and it is impossible to accurately judge the leakage situation and process the liquid at the leakage location, which easily causes the server in the computer room to fail to work normally due to the inability to detect and process the leakage in time. The application can accurately judge the leakage situation and process the leakage to ensure the normal operation of the server.

[0006] The first embodiment of the present application provides a server cabinet overflow prevention system, including:

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

[0008] A second detection module is used to detect the amount of liquid leakage at the bottom of the server cabinet and generate a side liquid level signal when the liquid level height of the server cabinet meets a preset signal generation condition;

[0009] A drive assembly for stretching a stretchable base plate at the bottom of a server cabinet;

[0010] A control module, configured to control the driving assembly to stretch the stretchable bottom plate according to the bottom leakage amount and / or the side liquid level signal when there is liquid leakage in the server cabinet;

[0011] The cooling capacity distribution module is used to extract the leaked liquid from the server cabinet according to the side liquid level signal.

[0012] Through the above technical scheme, when the first detection module is used to monitor the presence of liquid leakage in the server cabinet, the second detection module is used to detect the amount of leakage at the bottom of the server cabinet, and a side liquid level signal is generated when the liquid level reaches a preset condition, so that the control module controls the drive component to stretch the stretchable bottom plate, and the cooling capacity distribution module is used to extract the leaked liquid in the server cabinet according to the side liquid level signal, thereby quickly extracting the leaked liquid in the server cabinet and effectively preventing the leakage from further spreading to other areas inside the cabinet. This can not only reduce the damage to the server caused by the leakage, but also keep the inside of the cabinet 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 cabinet; the second detection unit is used to generate a side liquid level signal when the liquid level height of the server cabinet reaches the height of the position of the second detection unit.

[0015] Through the above technical scheme, the amount of liquid leakage at the bottom of the server cabinet is detected by the first detection unit, so that the initial liquid leakage can be discovered in time. The second detection unit is used to generate a side liquid level signal when the liquid level in the cabinet rises to its position, which can more accurately reflect the leakage inside the cabinet and improve the accuracy and sensitivity of monitoring.

[0016] Optionally, the control module includes:

[0017] A first control unit is used for controlling the driving assembly to stretch the stretchable bottom plate to seal the front window and the rear window of the server cabinet when there is liquid leakage in the server cabinet and the amount of liquid leakage at the bottom is greater than a preset amount of liquid leakage;

[0018] And / or, a second control unit is used to control the driving component to stretch the stretchable bottom plate according to a preset stretching step length until the second detection unit reaches a preset height when there is liquid leakage in the server cabinet and the second detection unit generates the side liquid level signal.

[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 actual conditions, which not only avoids the waste of resources caused by excessive response, but also ensures the effectiveness of the response measures.

[0020] Optionally, the second detection unit is disposed on a connector between the driving assembly and the stretchable bottom plate, so that when the second control unit controls the driving assembly to stretch the stretchable bottom plate according to the preset stretching step, the second detection unit moves following the stretching.

[0021] Through the above technical solution, 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 components, but also helps to reduce the installation and maintenance costs of the system.

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

[0023] Through the above technical solution, when liquid leakage 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 changes inside the cabinet, ensuring that the server operates within a safe temperature range and avoiding overcooling or insufficient cooling.

[0024] Optionally, the server cabinet overflow prevention system further includes:

[0025] The flow guide module corresponding to each server in the server cabinet is used to guide the leaked liquid to the bottom of the server cabinet when there is liquid leakage in the heat exchange component of the server cabinet.

[0026] Through the above technical solution, since each server has a corresponding diversion module, when leakage occurs, the leakage will be quickly diverted to the bottom of the cabinet, so that the operation and maintenance personnel can locate the source of the leakage more quickly and take timely and effective response measures, and avoid the leakage from directly contacting the server hardware, thereby reducing the potential damage of the leakage to the server.

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

[0028] Through the above technical solution, by determining the server to be powered off according to the position height of the second detection unit and performing the power-off operation in time, liquid leakage inside the server cabinet is effectively prevented and controlled, thereby protecting the safety of the server.

[0029] Optionally, the control module is further used to control a server corresponding to the server cabinet to be powered off when there is liquid leakage in the server cabinet.

[0030] Through the above technical solution, all servers are powered off through the control module when there is liquid leakage in the server cabinet, thereby achieving effective prevention and control of liquid leakage inside the server cabinet and protecting the safety of the server.

[0031] A second aspect of the present application is a server cabinet, which includes the above-mentioned server cabinet anti-overflow system.

[0032] A third aspect of the present application provides a method for preventing liquid overflow in a server cabinet, using the above-mentioned system for preventing liquid overflow in a server cabinet, wherein the method comprises the following steps:

[0033] Check server cabinets for liquid leaks;

[0034] Detecting the amount of liquid leakage at the bottom of the server cabinet, and generating a side liquid level signal when the liquid level height of the server cabinet meets a preset signal generation condition;

[0035] In the event of liquid leakage in the server cabinet, the driving assembly is controlled to stretch the stretchable bottom plate according to the bottom leakage amount and / or the side liquid level signal, and the leaked liquid in the server cabinet is extracted according to the side liquid level signal.

[0036] In the above implementation, the first detection module is used to detect whether there is liquid leakage in the server cabinet, the second detection module is used to detect the amount of liquid leakage at the bottom of the server cabinet, and a side liquid level signal is generated when the liquid level height of the server cabinet meets the preset signal generation condition, the drive component is used to stretch the stretchable bottom plate at the bottom of the server cabinet, and the control module controls the drive component to stretch the stretchable bottom plate 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 cabinet, and the cold distribution module is used to extract the leaked liquid from the server cabinet according to the side liquid level signal. Thus, the problem that the leakage detection method in the related art is simple, and the leakage processing configuration structure is simple, and it is impossible to accurately judge the leakage situation and process the liquid at the leakage location, which easily causes the problem that the server in the computer room cannot work normally due to the inability to detect and process the leakage in time, can be accurately judged The leakage situation and process the liquid at the leakage location, avoid the risk of the leaking server due to the leakage, and at the same time ensure that the servers at other locations can work normally without being affected by the server at the leakage location.

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

[0046] The following describes the server cabinet overflow prevention system, method and server cabinet of the embodiment of the present application with reference to the accompanying drawings. In view of the simple leakage detection method in the related art mentioned in the above background technology, and the simple leakage processing configuration structure, it is impossible to accurately judge the leakage situation and process the liquid at the leakage position, which easily causes the problem that the server in the computer room cannot work normally due to the inability to detect and process the leakage in time, the present application provides a server cabinet overflow prevention system, in which when the first detection module is used to monitor the existence of liquid leakage in the server cabinet, the second detection module is used to detect the amount of leakage at the bottom of the server cabinet, and a side liquid level signal is generated when the liquid level reaches a preset condition, so that the control module controls the drive component to stretch the stretchable bottom plate, and the cold distribution module is used to extract the leakage of the server cabinet according to the side liquid level signal, so as to quickly extract the leakage in the server cabinet, and effectively prevent the leakage from further spreading to other areas inside the cabinet, which can not only reduce the damage to the server caused by the leakage, but also keep the inside of the cabinet clean and dry, and provide a good environment for the stable operation of the server.

[0047] Specifically, Figure 1 A block diagram of a server cabinet overflow prevention system provided in an embodiment of the present application.

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

[0049] Among them, the first detection module 100 is used to detect whether there is liquid leakage in the server cabinet; the second detection module 200 is used to detect the amount of liquid leakage at the bottom of the server cabinet and generate a side liquid level signal when the liquid level height of the server cabinet meets the preset signal generation condition; the drive component 300 is used to stretch the stretchable bottom plate 700 at the bottom of the server cabinet; the control module 400 is used to control the drive component 300 to stretch the stretchable bottom plate 700 according to the bottom leakage amount and / or the side liquid level signal when there is liquid leakage in the server cabinet; the cooling capacity distribution module 500 is used to extract the leaked liquid from the server cabinet according to the side liquid level signal.

[0050] Among them, the first detection module 100 can be a liquid leakage detector, 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 driving component 300 can be a motor, the liquid leakage detector is arranged on the heat exchange structure of the server cabinet, a stretchable bottom plate 700 and a low liquid level detector 401 can be arranged under the server cabinet, and a high liquid level detector 402 can be arranged on the side of the server cabinet. The liquid leakage detector can be used to detect whether there is liquid leakage in the server cabinet, the low liquid level detector 401 is used to detect the amount of liquid leakage at the bottom of the server cabinet, the motor is located at the top of the server cabinet, and the high liquid level detector 402 is used to detect the liquid level height of the server cabinet. The structure of the server cabinet overflow prevention system is as shown in FIG. Figure 2 As shown, the side view schematic diagram of the server cabinet overflow prevention system is as shown Figure 3 As shown in (a), the top view schematic diagram of the server cabinet overflow prevention system is as follows Figure 3 As shown in (b), the preset signal generation condition is that there is leakage at the bottom of the server cabinet, but the leakage at the bottom does not reach the top of the server cabinet.

[0051] It should be noted that the structural schematic diagram of the server cabinet anti-overflow system in the embodiment of the present application is only an exemplary drawing.

[0052] It can be understood that the first detection module 100 repeatedly detects whether there is liquid leakage in the server cabinet according to a preset detection cycle, wherein the preset detection cycle can be set to 2 seconds to 5 seconds in the embodiment of the present application, and each detection signal is fed back to the control module 400. If the detection signal of the first detection module 100 is a leakage signal, the second detection module 200 detects the amount of leakage at the bottom of the server cabinet, and generates a side liquid level signal when the liquid level height of the server cabinet meets the preset signal generation condition. The control module 400 discharges the leakage and controls the server for protection according to the bottom leakage, or discharges the leakage and controls the server according to the side liquid level signal, or discharges the leakage and controls the server according to the bottom leakage 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 the current state and does not take any action.

[0053] Therefore, when the first detection module is used to monitor liquid leakage in the server cabinet, the second detection module is used to detect the amount of leakage at the bottom of the server cabinet, and a side liquid level signal is generated when the liquid level reaches a preset condition, so that the control module controls the drive component to stretch the stretchable bottom plate, and the cooling capacity distribution module is used to extract the leaked liquid in the server cabinet according to the side liquid level signal, thereby quickly extracting the leaked liquid in the server cabinet and effectively preventing the leakage from further spreading to other areas inside the cabinet. This can not only reduce the damage to the server caused by the leakage, but also keep the inside of the cabinet 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, used to detect the amount of liquid leakage at the bottom of the server cabinet; and a second detection unit, used to generate a side liquid level signal when the liquid level of the server cabinet reaches the height of the second detection unit.

[0055] It is understandable that if the second detection module 200 detects the amount of bottom liquid leakage, and the second detection unit detects the liquid leakage to the point where the liquid level in the server cabinet reaches the height where the second detection unit is located, a side liquid level signal is generated.

[0056] Therefore, by detecting the amount of leakage at the bottom of the server cabinet through the first detection unit, the initial liquid leakage can be discovered in time. By using the second detection unit to generate a side liquid level signal when the cabinet liquid level rises to its position, the leakage inside the cabinet can be more accurately reflected, thereby 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 used to control the drive assembly 300 to stretch the stretchable bottom plate 700 to seal the front window and rear window of the server cabinet when there is liquid leakage in the server cabinet and the amount of bottom leakage is greater than a preset amount of leakage; and / or the second control unit is used to control the drive assembly 300 to stretch the stretchable bottom plate 700 according to a preset stretching step length when there is liquid leakage in the server cabinet and the second detection unit generates a side liquid level signal until the second detection unit reaches a preset height.

[0058] The first detection unit is a detection unit for detecting the amount of liquid leakage at the bottom of the server cabinet. Figure 2 As shown, the first detection unit may be a low liquid level detector 401, and the second detection unit may be a detection unit for generating 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 cabinet; the preset leakage amount can be a threshold value pre-set by the user, a threshold value obtained through a limited number of experiments, or a threshold value obtained through a limited number of computer simulations, which is not specifically limited here.

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

[0060] If the second detection module 200 detects the amount of liquid leakage at the bottom, and the second detection unit generates a side liquid level signal when the liquid level height in the server cabinet reaches the height of the second detection unit, at this time, the second control unit controls the driving component 300 to stretch the stretchable bottom plate 700 according to the preset stretching step length, and the second detection unit moves along with the stretching of the stretchable bottom plate 700 until the second detection unit reaches the top of the server cabinet and the driving component 300 stops rotating. At the same time, when the second detection unit generates a side liquid level signal, the liquid replenishment pump of the cold distribution module 500 is started, and the liquid in the server cabinet is filtered through the filter and drawn into the liquid supply pipeline, so that the liquid is recycled. When the reading of the flow meter in the cold distribution module 500 is close to zero and the liquid level detector at the bottom of the server cabinet does not detect the bottom liquid leakage, the liquid 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 bottom plate 700 in steps of 1U, and the high liquid level detector 402 follows the stretchable bottom plate 700 and moves in steps of 1U until the high liquid level detector 402 reaches the top of the server cabinet. At the same time, the liquid replenishment pump is started, and the liquid in the server cabinet is filtered through the filter and drawn into the cooling distribution module 500, so that the liquid is recycled. When the reading of the flow meter in the cooling distribution module 500 is close to zero and the liquid level detector at the bottom of the server cabinet does not detect any leakage at the bottom, the liquid 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 actual conditions, which not only avoids the waste of resources caused by excessive response, but also ensures the effectiveness of the response measures.

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

[0064] It should be noted that in the server field, the preset stretching step is 1U. 1U is the unit of height of a rack-mounted server. 1U is equal to 1.75 inches, approximately 4.445 cm. The "preset stretching 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] It can be understood that the high liquid level detector is arranged on the connecting piece between the motor and the stretchable bottom plate 700, and is used to drive the high liquid level detector to move when the stretchable bottom 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 components, but also helps to reduce the installation and maintenance costs of the system.

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

[0068] It can be understood that a flow guide module 600 is correspondingly provided for each server in the server cabinet, which is used to discharge the leaked liquid to the bottom of the server cabinet through the drain port when there is leakage in the heat exchange component of the server cabinet.

[0069] As an embodiment, the flow guide module 600 can be designed to have a structure with a guide groove or a guide pipe, which can guide the leaked liquid to flow along a specific path. In terms of material, the flow guide module 600 is usually made of corrosion-resistant and wear-resistant materials to ensure its reliability and stability in long-term use. When a heat exchange component (such as a coolant pipe, a radiator, etc.) in a server cabinet leaks, the leaked liquid will first contact the flow guide module 600, and the flow guide module 600 will quickly guide the leaked liquid to the bottom of the server cabinet through its guide groove or guide pipe.

[0070] Therefore, since each server has a corresponding diversion module, when leakage occurs, the leakage will be quickly diverted to the bottom of the cabinet, allowing operation and maintenance personnel to locate the source of the leakage more quickly and take timely and effective response measures, and avoid the leakage from directly contacting the server hardware, thereby reducing the potential damage of the leakage to the server.

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

[0072] The preset step size may be a threshold value pre-set by a user, a threshold value obtained through a finite number of experiments, or a threshold value obtained through a finite number of computer simulations. In an embodiment of the present application, the preset step size is 2U.

[0073] Specifically, when the second detection unit moves following the stretchable bottom plate 700, if the total stretching step length of the second detection unit is greater than the preset step length, the cooling capacity distribution module 500 controls the liquid supply and return according to the valve switching angle of the liquid supply pipeline, specifically controlling the valve switching angle of the liquid supply pipeline based on the current height of the second detection unit.

[0074] For example, when the total stretching step length of the high liquid level detector 402 is less than or equal to 2U, the valve switch angle remains unchanged. When the total stretching step length of the high liquid level detector 402 is greater than 2U, the cooling capacity distribution module 500 determines the valve switch angle of the liquid supply pipeline of the server cabinet according to the current height of the high liquid level detector 402. When the total stretching step length of the high liquid level detector 402 exceeds 40U, the valve 800 of the liquid supply pipeline is closed. The specific valve switch angle adjustment formula is:

[0075] n=n 现 *(1-current height of high liquid level detector\height of server cabinet).

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

[0077] Therefore, 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 changes inside the cabinet, ensuring that the server operates within a safe temperature range and avoiding overcooling or undercooling.

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

[0079] The server to be powered off is a server that is about to be powered off.

[0080] It can be understood that when the second detection unit generates a side liquid level signal, the second control unit controls the driving component 300 to stretch the stretchable bottom plate 700 according to a preset stretching step length. When the second detection unit moves with the stretchable bottom plate 700, the server to be powered off at the corresponding position is powered off when the second detection unit moves.

[0081] Therefore, by determining the server to be powered off according to the position height of the second detection unit and performing the power-off operation in time, liquid leakage inside the server cabinet is effectively prevented and controlled, thereby protecting the safety of the server.

[0082] Optionally, in some embodiments, the control module 400 is further used to control power off of a server corresponding to the server cabinet when there is liquid leakage in the server cabinet.

[0083] It is understandable that if there is liquid leakage in the server cabinet, the control module 400 controls the server corresponding to the server cabinet to be powered off.

[0084] Therefore, when there is liquid leakage in the server cabinet, the control module can cut off the power supply to all servers, thereby achieving effective prevention and control of liquid leakage inside the server cabinet and protecting the safety of the server.

[0085] In order to enable those skilled in the art to further understand the server cabinet overflow prevention system of the embodiment of the present application, the following is combined with Figure 4 and Figure 5 Elaborate in detail.

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

[0087] In step S501, the server cabinet overflow prevention system is started.

[0088] In step S502, the leakage detector at the bottom plate end of the server repeats the leakage detection on the server cabinet three times according to the preset detection cycle, and the detection signal of each time 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 no leakage signal, the system controls the server to maintain the current state and does not take any action.

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

[0090] While executing step S504, execute step S505.

[0091] In step S504, if the leakage detector detects that there is leakage in the server cabinet, and the low liquid level detector at the bottom plate end of the server detects that the leakage at the bottom is greater than the preset leakage amount, the liquid is discharged from the server into the server cabinet through the drain port through the diversion module corresponding to the server, and the bottom of the server cabinet is sealed to prevent liquid from leaking out of the cabinet, and step S506 is executed at the same time.

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

[0093] In step S506, the first control unit controls the motor to stretch the stretchable bottom plate to seal the front window and the rear window of the server cabinet, and the motor stops, and the stretchable bottom plate is reset after the server is powered on again.

[0094] In step S507, the low liquid level sensor in the server cabinet 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 bottom plate according to 1U, the high liquid level detector moves with the stretchable bottom plate, the liquid replenishment pump of the cold distribution module is started, and the liquid in the server cabinet is filtered through the filter and drawn into the liquid supply pipeline, so that the liquid is recycled. While executing step S508, execute step S509 or step S511.

[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 detector reaches the top of the cabinet, and the motor stops. While executing step S509, step S510 is executed.

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

[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 move, and step S513 is specifically executed.

[0100] In step S513, the valve switch angle of the liquid supply pipeline of the server cabinet is determined according to the current height of the high liquid level detector, and the liquid supply and return control is performed according to the valve switch angle until the high liquid level detector reaches the top of the server cabinet, the valve is closed, and the valve is opened after the server is powered on again.

[0101] According to the server cabinet overflow prevention system proposed in the embodiment of the present application, when the first detection module is used to monitor the existence of liquid leakage in the server cabinet, the second detection module is used to detect the amount of leakage at the bottom of the server cabinet, and a side liquid level signal is generated when the liquid level reaches a preset condition, so that the control module controls the drive component to stretch the stretchable bottom plate, and the cold distribution module is used to extract the leaked liquid from the server cabinet according to the side liquid level signal. Thus, the problem that the leakage detection method in the related art is simple, and the leakage processing configuration structure is simple, and it is impossible to accurately judge the leakage situation and process the liquid at the leakage location, which easily causes the server in the computer room to not work normally due to the inability to detect and process the leakage in time, can be accurately judged The leakage situation and process the liquid at the leakage location, avoid the risk of the leaking server due to the leakage, and at the same time ensure that the servers at other locations can work normally without being affected by the server at the leakage location.

[0102] Next, a method for preventing liquid overflow in a server cabinet according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0103] Figure 6 It is a block diagram of a method for preventing liquid overflow in a server cabinet according to an embodiment of the present application.

[0104] like Figure 6 As shown, the server cabinet spill prevention method includes the following steps:

[0105] In step S601, it is detected whether there is liquid leakage in the server cabinet.

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

[0107] In step S603, when there is liquid leakage in the server cabinet, the driving component is controlled to stretch the stretchable bottom plate according to the bottom leakage amount and / or the side liquid level signal, and the leaked liquid in the server cabinet is extracted according to the side liquid level signal.

[0108] It should be noted that the aforementioned explanation of the server cabinet overflow prevention system embodiment is also applicable to the server cabinet overflow prevention method of this embodiment, and will not be repeated here.

[0109] According to the server cabinet overflow prevention method proposed in the embodiment of the present application, it is detected whether there is liquid leakage in the server cabinet, the amount of liquid leakage at the bottom of the server cabinet is detected, and a side liquid level signal is generated when the liquid level height of the server cabinet meets the preset signal generation condition. In the case of liquid leakage in the server cabinet, the drive component is controlled to stretch the stretchable bottom plate according to the amount of liquid leakage at the bottom and / or the side liquid level signal, and the leaked liquid in the server cabinet is extracted according to the side liquid level signal. Thus, the problem that the leakage detection method in the related art is simple, and the leakage processing configuration structure is simple, and it is impossible to accurately judge the leakage situation and process the liquid at the leakage location, which easily causes the server in the computer room to not work normally due to the inability to detect and process the leakage in time, can be accurately judged The leakage situation and process the liquid at the leakage location, avoid the risk of the leaking server due to the leakage, and at the same time ensure that the servers at other locations can work normally without being affected by the server at the leakage location.

[0110] In addition, an embodiment of the present application also provides a server cabinet, which includes the above-mentioned server cabinet anti-overflow system.

[0111] The server cabinet proposed in the embodiment of the present application solves the problem that the leakage detection method in the related art is simple and the leakage processing configuration structure is simple, which cannot accurately determine the leakage situation and process the liquid at the leakage location, and easily causes the problem that the server in the computer room cannot work normally due to the inability to detect and process the leakage in time. The server cabinet can accurately determine the leakage situation and process the liquid at the leakage location, avoiding the risk of the leaking server due to the leakage, and at the same time ensuring that the servers at other locations can work normally without being affected by the servers at the leakage location.
