Description

Technical Field

[0001] The present disclosure relates to the field of data center infrastructure, and more particularly, to a liquid leakage detection device for a liquid-cooled server, a liquid leakage treatment device for a liquid-cooled server, a liquid cooling system, and a liquid leakage method for a liquid-cooled server. Background Art

[0002] With the growth of the business demand for data centers in various industries, and the high degree of integration of IT equipment and power supply and distribution systems in data center computer rooms, high-density deployment has become the development trend of new and renovated data centers. As a result, the heat dissipation per unit space in the computer room has gradually increased. Currently, most data center computer rooms still use traditional air-cooling technology, that is, the heat dissipated by the server is brought to the end air conditioner for heat exchange. The air-cooling on the server side limits the further improvement of the computer room density. Liquid-cooled servers have emerged and are suitable for application in high-density scenarios. In recent years, they have been rapidly developed and tried to be promoted. The application of liquid-cooled servers not only reduces or eliminates the compression refrigeration link, but also the server can quickly take away the heat dissipated by the main components such as the CPU through liquid cooling, control the temperature of the server core components at a low level, improve the performance of the core components, and delay the service life, which are difficult to achieve for air-cooled servers.

[0003] In the process of implementing the concept of the present disclosure, the inventors found that at least the following problems exist in the related art:

[0004] A liquid-cooled server is a new type of server that uses liquids such as pure water and fluorinated liquid to replace air and directly guides the refrigerant to the heat sources (heating elements such as server CPUs and memories) to achieve the heat dissipation of server components. The refrigeration liquid flows into each server through pipelines, takes away the heat inside the server and flows out to realize the refrigeration liquid circulation. When the liquid enters the server, there is inevitably a risk of liquid leakage from the pipelines. If the liquid leaks and the corresponding server cannot be shut down in time, it will cause certain safety hazards. Summary of the Invention

[0006] One aspect of the present disclosure provides a liquid leakage detection device for a liquid-cooled server, including: an inlet pipeline configured to be connected to the inlet of the liquid-cooled server; an outlet pipeline configured to be connected to the outlet of the liquid-cooled server; and a differential pressure sensing component connected to the inlet pipeline and the outlet pipeline and configured to sense the differential pressure between the inlet pipeline and the outlet pipeline, and issue a sensing signal when the differential pressure between the inlet pipeline and the outlet pipeline is greater than the initial differential pressure to trigger the shutdown of the liquid-cooled server.

[0017] According to an embodiment of the present disclosure, the method further includes: controlling a valve of the inlet pipe to close when the current differential pressure between the inlet pipe and the outlet pipe is greater than the initial differential pressure.

[0018] According to an embodiment of the present disclosure, the obtaining the current differential pressure information between the inlet pipe and the outlet pipe includes: receiving a sensing signal from a differential pressure sensing component connected to the inlet pipe and the outlet pipe and using the sensing signal as the differential pressure information.

[0019] According to an embodiment of the present disclosure, determining whether the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference based on the pressure difference information includes: in response to receiving the pressure difference information from the pressure difference sensing component, determining that the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference; or the pressure difference information includes the value of the current pressure difference between the water inlet pipe and the water outlet pipe, and determining whether the value of the current pressure difference is greater than the initial pressure difference.

Moreover, once liquid leakage occurs in the liquid-cooled server, the pressure inside the liquid-cooled server will be released, and coupled with the loss of liquid, the pressure difference between the inlet and outlet water pipes will change relatively quickly and significantly. The liquid leakage detection device of the present disclosure is particularly suitable for timely shutting off the power supply and water supply in the case of large-flow water leakage caused by pipeline rupture or interface rupture. Since the pressure release inside the liquid circulation system is more obvious and the pressure drop is large in the case of large-flow water leakage, the pressure difference between the inlet and outlet water pipes changes more significantly. The current water supply pipelines of liquid-cooled servers are mainly made of aluminum alloy or copper pipes, and the service life of the server is about 5 years. The circulating liquid is basically non-corrosive, so there is less leakage caused by corrosion. The probability of water leakage caused by rupture or cracks in the pipeline itself and the interface is relatively high. Description of the Drawings

Embodiments of the present disclosure also provide a liquid leakage treatment device for a liquid-cooled server and a liquid cooling system.

[0039] Figure 1 An exemplary application scenario in which the liquid leakage detection device can be applied according to an embodiment of the present disclosure is schematically shown. It should be noted that Figure 1 What is shown is only an example of an application scenario to which embodiments of the present disclosure can be applied, to help those of ordinary skill in the art understand the technical content of the present disclosure, but it does not mean that embodiments of the present disclosure cannot be used in other devices, systems, environments, or scenarios.

[0040] As Figure 1 shown, the liquid leakage detection device of the embodiment of the present disclosure can be used to detect liquid leakage of a liquid-cooled server.

[0041] A liquid-cooled server is a new type of server that uses liquids such as pure water and fluorinated liquids to replace air, directly guiding the refrigerant to heat sources (heating components such as server CPUs and memories) to achieve heat dissipation of server components. According to the heat dissipation contact method between the liquid and the heat dissipation component, liquid-cooled servers can be divided into cold plate type (indirect type), immersion type (direct type), and spray type. Among them, the cold plate (water pipe) covers heating components such as CPUs and GPUs. The server components do not directly contact the liquid. The cost of the used refrigeration liquid is relatively low, and the modification compared with the existing air-cooled servers is small. Compared with the other two methods, it has been the most widely promoted and has become the mainstream product of current liquid-cooled servers. The deployment of liquid-cooled servers generally consists of parts such as a cooling tower, external pipes of the computer room, a heat exchange unit (CDU), internal pipes of the computer room, a cabinet and a liquid distribution unit, and liquid-cooled servers. After the refrigeration liquid reaches the liquid distribution unit, the liquid distribution unit sends the refrigeration liquid into each server, takes away the heat inside the server and flows back to the liquid distribution unit.

[0042] The liquid leakage detection device for a liquid-cooled server according to an embodiment of the present disclosure can be applied to various forms of liquid-cooled servers, especially suitable for cold plate type liquid-cooled servers. The liquid leakage detection device 101 can be arranged between the liquid supply device 102 and each server 103. The liquid leakage detection device 101 and the server 103 can be in a one-to-one correspondence relationship. Among them, the liquid supply device 102 can be, for example, the above-mentioned liquid distribution unit, or can also refer to a system that provides liquid refrigeration transportation including a cooling tower, a heat exchange unit, and a liquid distribution unit.

[0043] The liquid leakage detection device according to an embodiment of the present disclosure can determine whether a corresponding server leaks by detecting the pressure difference between the water inlet pipe and the water outlet pipe, and send an induction signal when the corresponding server leaks to trigger the shutdown of the server.

[0044] Figure 2 Schematically shows a schematic diagram of the composition of a liquid leakage detection device for a liquid-cooled server according to an embodiment of the present disclosure.

[0045] Figure 3 Schematically shows an external view schematic diagram of a liquid leakage detection device for a liquid-cooled server according to an embodiment of the present disclosure.

[0046] As Figure 2 and Figure 3 shown, the liquid leakage detection device 200 can include a water inlet pipe 210, a water outlet pipe 220, and a pressure difference induction component 230.

[0047] According to an embodiment of the present disclosure, the inlet pipe 210 is configured to be connected to the inlet of the liquid-cooled server. For example, one end of the inlet pipe 210 can be directly or indirectly connected to the inlet of the liquid-cooled server, and the other end of the inlet pipe 210 can be directly or indirectly connected to the outlet of the liquid supply device. The relatively low-temperature liquid output by the liquid supply device flows through the inlet pipe 210 of the liquid leakage detection device 200 and then flows into the liquid-cooled server to cool the heat-generating components in the liquid-cooled server, taking away the heat dissipated by the main heat-generating components (such as CPU, memory, etc.) of the server, and the temperature of the coolant rises. As Figure 3 shown, each of the two ends of the inlet pipe 210 can be provided with an interface 211. The interface 211 on the side close to the liquid-cooled server can be used to connect to the inlet of the liquid-cooled server or to the inlet pipe of the liquid-cooled server, and the interface 211 on the side close to the liquid supply device can be used to connect to the outlet of the liquid supply device or to the outlet pipe of the liquid supply device.

[0048] According to an embodiment of the present disclosure, the outlet pipe 220 is configured to be connected to the outlet of the liquid-cooled server. For example, one end of the outlet pipe 220 can be directly or indirectly connected to the outlet of the liquid-cooled server, and the other end of the outlet pipe 220 can be directly or indirectly connected to the inlet of the liquid supply device. After the relatively high-temperature liquid that has exchanged heat with the heat-generating components in the liquid-cooled server flows out of the liquid-cooled server, it then flows through the outlet pipe 220 of the liquid leakage detection device 200 and into the liquid supply device, and the liquid supply device can re-cool the liquid or send the liquid to the upper-level cooling device for re-cooling. As Figure 3 shown, each of the two ends of the outlet pipe 220 can also be provided with an interface 221. The interface 221 on the side close to the liquid-cooled server can be used to connect to the outlet of the liquid-cooled server or to the outlet pipe of the liquid-cooled server, and the interface 221 on the side close to the liquid supply device can be used to connect to the inlet of the liquid supply device or to the inlet pipe of the liquid supply device.

[0049] According to an embodiment of the present disclosure, the differential pressure sensing assembly 230 is connected to the inlet pipe 210 and the outlet pipe 220, and is configured to sense the differential pressure between the inlet pipe 210 and the outlet pipe 220, and issue a sensing signal when the differential pressure between the inlet pipe 210 and the outlet pipe 220 is greater than the initial differential pressure to trigger the shutdown of the power supply of the liquid-cooled server.

[0050] For example, when there is no liquid leakage in the liquid-cooled server, there is a certain pressure difference between the water inlet pipe 210 and the water outlet pipe 220, and the pressure of the water inlet pipe 210 is greater than that of the water outlet pipe 220. The initial pressure difference may refer to the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 when there is no liquid leakage in the liquid-cooled server. When liquid leakage occurs in the liquid-cooled server, due to the release of the pressure inside the liquid-cooled server and the loss of liquid, the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 will further increase, that is, the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 will increase from the initial pressure difference. In this case, the pressure difference sensing component 230 will sense the change in the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 and send an induction signal when the pressure difference increases. The induction signal can be an electrical signal. For example, the induction signal can be sent to the control device so that the control device can control the power supply of the liquid-cooled server to be turned off according to the induction signal to avoid losses.

[0051] According to an embodiment of the present disclosure, the liquid leakage detection device can sense the pressure difference between the inlet and outlet water pipes of the liquid-cooled server and determine whether liquid leakage occurs in the liquid-cooled server by detecting the pressure difference between the inlet and outlet water pipes. When liquid leakage is detected, an induction signal can be sent to turn off the liquid-cooled server. Therefore, the liquid leakage detection device of the embodiment of the present disclosure can eliminate the safety risks caused by liquid leakage of the liquid-cooled server, improve the operation reliability of the liquid-cooled server, reduce the safety hazards of liquid leakage, promote the popularization and use of the liquid-cooled server, and promote the improvement of the construction density of the computer room and the construction of a green data center. Moreover, the pressure inside the liquid-cooled server is greater than the atmospheric pressure. Once liquid leakage occurs in the liquid-cooled server (for example, liquid leakage caused by the rupture of the internal liquid circulation pipeline and its interface of the liquid-cooled server), the pressure inside the liquid-cooled server will be released. Coupled with the loss of liquid, the pressure difference between the inlet and outlet water pipes will change more rapidly and significantly. The change in the pressure difference between the inlet and outlet water pipes is more obvious than the change in flow rate. Therefore, liquid leakage can be detected in time and corresponding measures can be taken in time. The liquid leakage detection device of the embodiment of the present disclosure is particularly suitable for timely shutting off the power supply and water supply in the case of large-flow water leakage caused by the rupture of the internal liquid circulation pipeline and its interface of the liquid-cooled server. Since the pressure release inside the liquid circulation system is more obvious and the pressure drop is larger in the case of large-flow water leakage, the pressure difference between the inlet and outlet water pipes changes more significantly. Currently, the water supply pipelines of liquid-cooled servers are mainly made of aluminum alloy or copper pipes, and the service life of the servers is about 5 years. The circulating liquid is basically non-corrosive, so there is less leakage caused by corrosion. The probability of water leakage caused by rupture or crack between the pipeline itself and the interface is relatively high. In addition, the liquid leakage detection device is connected to existing equipment through an interface, with little change to the deployment architecture of existing equipment. Its internal packaging and external structure are simple and beautiful, facilitating installation.

[0052] Figure 4Schematically shows a structural diagram of a liquid leakage detection device according to an embodiment of the present disclosure.

[0053] As Figure 4 shown, according to an embodiment of the present disclosure, the differential pressure sensing assembly 230 may include a differential pressure membrane 231, a slide rod 232, and a touch element 233.

[0054] According to an embodiment of the present disclosure, the differential pressure membrane 231 is disposed between the water inlet pipe 210 and the water outlet pipe 220 and deforms when the differential pressure between the water inlet pipe 210 and the water outlet pipe 220 is greater than the initial differential pressure.

[0055] For example, the differential pressure sensing assembly 230 may further include a chamber 234. The chamber 234 may communicate with the water inlet pipe 210 and the water outlet pipe 220. The differential pressure membrane 231 is disposed in the chamber 234 and isolates the water inlet pipe 210 and the water outlet pipe 220. The differential pressure membrane 231 divides the chamber 234 into two parts. The first part communicates with the water inlet pipe 210, and the second part communicates with the water outlet pipe 220. Among them, the differential pressure membrane 231 may be a precision differential pressure membrane (the accuracy of related differential pressure products on the market can reach 0.5%, and the measurement range is 0-40 Mpa). When the differential pressure between the water inlet pipe 210 and the water outlet pipe 220 changes, it will cause the differential pressure membrane 231 to deform. For example, when the pressure of the water outlet pipe 220 decreases, thereby increasing the differential pressure between the water inlet pipe 210 and the water outlet pipe 220, the differential pressure membrane 231 will deform towards the water outlet pipe 220 side.

[0056] According to an embodiment of the present disclosure, the slide rod 232 is fixedly connected to the differential pressure membrane 231 and moves when the differential pressure membrane 231 deforms.

[0057] For example, the slide rod 232 may penetrate through the differential pressure membrane 231 and be fixedly connected to the differential pressure membrane 231. The slide rod 232 may be disposed at the central position of the differential pressure membrane 231. A sealing measure may be taken between the differential pressure membrane 231 and the slide rod 232. When the differential pressure membrane 231 deforms, it will drive the slide rod 232 to move. For example, when the differential pressure membrane 231 undergoes a phase change upward as Figure 4 shown, it will drive the slide rod 232 to move upward.

[0058] According to an embodiment of the present disclosure, the touch element 233 contacts the first end of the slide rod 232 and emits an induction signal when the slide rod 232 moves from the initial position to the first position. The first position may refer to the position where the slide rod 232 is located when the first end of the slide rod 232 touches the touch element 233.

[0059] For example, when there is no liquid leakage in the liquid-cooled server, the sliding rod 232 is in the initial position. When liquid leakage occurs in the liquid-cooled server, the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 increases. The pressure difference membrane 231 will deform towards the water outlet pipe 220, and the sliding rod 232 will move towards the corresponding side accordingly. A touch element 233 is provided at a position close to the first end of the sliding rod 232. When the sliding rod 232 moves to make its first end touch the touch element 233, the touch element 233 will send an induction signal to the control device when being touched or pressed. The control device can then control the shutdown of the liquid-cooled server when receiving the induction signal. Among them, the touch element 233 can be, for example, a touch switch or a piezoelectric sensor.

[0060] According to an embodiment of the present disclosure, a pressure difference membrane is provided between the water inlet pipe and the water outlet pipe, and the pressure difference membrane drives the sliding rod to slide and then touch the touch element. The touch element sends an induction signal when being touched or pressed. Based on this solution, the pressure difference between the inlet and outlet water pipes can be sensed quickly and sensitively, and an induction signal is triggered when the pressure difference increases.

[0061] According to an embodiment of the present disclosure, the pressure difference sensing assembly may further include a blocking member 235. The blocking member 235 is configured to: when the pressure difference between the water inlet pipe 210 and the water outlet pipe 220 is the initial pressure difference, limit the first end of the sliding rod 232 to the first side of the blocking member to limit the sliding rod 232 to the initial position, and limit the first end of the sliding rod 232 to the second side of the blocking member after the sliding rod 232 moves and pushes open the blocking member.

[0062] The blocking member 235 may include, for example, two spring rods. The ends of the two spring rods are close to each other to form a bayonet. The first end of the sliding rod 232 abuts against the bayonet. For example, the ends of the two spring rods form a bayonet with a triangular cross-section. Correspondingly, the cross-section of the first end of the sliding rod 232 is triangular (for example, the first end of the sliding rod 232 is arrow-shaped). The first end of the sliding rod 232 abuts against the triangular bayonet and fits with the bayonet. The force required for the first end of the sliding rod 232 to pass through the bayonet from bottom to top is smaller, while a larger force is required when the first end of the sliding rod 232 passes through the bayonet from top to bottom, realizing a one-way locking function. When there is no leakage in the liquid-cooled server, the bayonet limits the sliding rod 232 to the initial position. When liquid leakage occurs in the liquid-cooled server, the sliding rod 232 moves and pushes open the bayonet. The first end of the sliding rod 232 moves above the bayonet, and the bayonet can lock the first end of the sliding rod 232 above the bayonet, preventing the first end of the sliding rod 232 from moving back below the bayonet at will.

[0063] According to an embodiment of the present disclosure, the differential pressure sensing assembly may further include a spring 236, which is connected between the blocking member 235 and the fixed structure 237, and provides a blocking force for the blocking member 235 to counteract the acting force of the initial differential pressure between the water inlet pipe 220 and the water outlet pipe 230 on the differential pressure membrane, thereby balancing the forces on both sides of the differential pressure membrane when the liquid cooling server does not leak.

[0064] As described above, when there is no liquid leakage in the liquid cooling server, there is an initial differential pressure between the water inlet pipe 210 and the water outlet pipe 220. The differential pressure membrane 231 will have an initial deformation under the action of the initial differential pressure. In order to balance the initial differential pressure, a reverse force equivalent to the initial differential pressure is applied to the differential pressure membrane 231 through the blocking member 235, the spring 236, and the sliding rod 232, so that the differential pressure membrane 231 remains in a non-deformed state.

[0065] According to an embodiment of the present disclosure, the differential pressure sensing assembly is further configured to block the water inlet pipe 210 when the differential pressure between the water inlet pipe 210 and the water outlet pipe 220 is greater than the initial differential pressure.

[0066] According to an embodiment of the present disclosure, the differential pressure sensing assembly further includes a piston 238, which is fixedly connected to the second end of the sliding rod 232 and is configured to block the water inlet pipe 210 when the sliding rod 232 moves to the first position.

[0067] For example, a flow port 239 is provided in the first part of the chamber 234, and the liquid flowing into the first part of the chamber 234 from the water inlet pipe 210 needs to flow through the flow port 239. The second end of the sliding rod 232 passes through the flow port 239 and there is a certain gap between the second end of the sliding rod 232 and the flow port 239. The piston 238 is disposed at the second end of the sliding rod 232. When the sliding rod 232 is in the initial position, the piston 238 is spaced apart from the flow port 239 by a certain distance, and there is a certain gap between them for the liquid to flow through. When a liquid leakage occurs, the differential pressure membrane 238 drives the sliding rod 232 to move from the initial position to the first position. During the movement of the sliding rod 232, the distance between the piston 238 and the flow port 239 gradually decreases. When the sliding rod 232 reaches the first position, the piston 238 fits with the flow port 239, and the liquid is blocked and cannot continue to flow, blocking the water inlet channel 210 and cutting off the water supply.

[0068] According to an embodiment of the present disclosure, by providing a piston on the sliding rod, on the one hand, the water inlet pipe can be blocked in time when the liquid cooling server leaks, and on the other hand, the amount of liquid flowing into the liquid cooling server can be gradually reduced during the movement of the sliding rod, which can further increase the differential pressure between the water inlet pipe and the water outlet pipe, accelerate the movement of the sliding rod, and thus close the liquid cooling server and the water inlet pipe more quickly.

[0069] According to an embodiment of the present disclosure, the differential pressure sensing assembly may further include a first magnetic member and a second magnetic member. The first magnetic member may be fixedly disposed on the touch element 233, and the second magnetic member may be fixedly disposed on the first end of the slide rod 232. When the distance between the first magnetic member and the second magnetic member is less than a predetermined distance, the first magnetic member and the second magnetic member attract each other.

[0070] For example, when the first end of the slide rod 232 passes through the bayonet, since the distance between the first end of the slide rod 232 and the touch element 233 decreases, the suction force between the magnetic members of the two increases. The adsorption force between the first magnetic member and the second magnetic member can assist the first end of the slide rod 232 to pass through the bayonet, and when the first end of the slide rod 232 touches the touch element 233, it can give a relatively large pressing force to the touch element 233, ensuring that the touch element 233 is triggered and the touch element 233 emits an induction signal.

[0071] According to an embodiment of the present disclosure, the liquid leakage detection device may serve as a liquid leakage self-locking linkage valve, and the liquid leakage self-locking control valve may be installed between the cabinet liquid distribution unit and the liquid-cooled server. When the system is working normally (there is no liquid leakage inside the liquid-cooled server), the piston in the liquid leakage detection device remains open, providing circulating cooling liquid to the server. The liquid that has undergone heat exchange in the server can flow through the liquid leakage detection device and return to the cabinet liquid distribution unit to the upper-level refrigeration cycle system. When a leak occurs inside the server, at this time, part of the pressure in the circulation system is released inside the server, and the differential pressure between the water inlet side and the water outlet side of the liquid leakage detection device increases. At this time, the pressure on the water inlet side of the differential pressure membrane is greater than the pressure on the water outlet side, the differential pressure membrane deforms towards the water outlet side, and locks the slide rod through the spring and the bayonet device. At the same time, the top of the connecting rod touches the touch element. The differential pressure membrane and the water inlet control piston are fixed on the slide rod. When the differential pressure membrane deforms towards the water outlet side and locks, the piston follows and cuts off the water supply on the water inlet side. The slide rod touches the switch, and outputs a control signal to the server power switch through the control device to cut off the power supply of the server. It realizes the automatic isolation and shutdown of water and electricity, eliminating the safety risks caused by liquid leakage.

[0072] Figure 5 Schematically shows a schematic diagram of a liquid leakage detection device according to another embodiment of the present disclosure.

[0073] As Figure 5 shown, according to another embodiment of the present disclosure, the differential pressure sensing assembly may include a capacitive differential pressure sensor 331. The capacitive differential pressure sensor 331 is connected between the water inlet pipe 210 and the water outlet pipe 220, and is configured to sense the differential pressure between the water inlet pipe 210 and the water outlet pipe 220, and emit an induction signal when the differential pressure between the water inlet pipe 210 and the water outlet pipe 220 is greater than the initial differential pressure.

[0074] Figure 6Schematically shows a schematic diagram of a capacitive differential pressure sensor according to another embodiment of the present disclosure.

[0075] As Figure 6 shown, the capacitive differential pressure sensor 330 may have two chambers 331 and 332. The chambers 331 and 332 may be isolated by a diaphragm 333. A first electrode 334 may be provided on each side of the diaphragm 333, and a second electrode 335 may be provided on each of the two side wall surfaces opposite to the diaphragm 333. A capacitor is formed between the first electrodes 334 on both sides of the diaphragm and the second electrodes 335 on the two side wall surfaces respectively. The two measured media (inlet pipe fluid and outlet pipe fluid) can be introduced into the two chambers respectively, so that the pressures of the media on both sides act on the diaphragm. When the differential pressure on both sides increases, the diaphragm 333 deforms, and the distance between the diaphragm 333 and the two side wall surfaces changes accordingly, thereby changing the distance between the two electrodes of the capacitor and generating an induction signal. The capacitive differential pressure sensor 330 can send the induction signal to a control device so that the control device controls the power supply of the liquid-cooled server to be turned off.

[0076] According to an embodiment of the present disclosure, an electric valve may be provided on the inlet pipe. When the control device receives the induction signal sent by the capacitive differential pressure sensor 330, it can control the electric valve on the inlet pipe to close and cut off the water supply.

[0077] The liquid leakage detection device according to the embodiment of the present disclosure can quickly cut off the water supply and power supply of the liquid-cooled server. The device has a low cost and occupies a small space. Without changing the existing architecture of the liquid-cooled server, it only needs to be installed between the cabinet liquid distribution unit and the server water inlet and outlet to detect liquid leakage and ensure timely response and cut off the water supply and power supply in case of liquid leakage in the liquid-cooled server.

[0078] Another aspect of the embodiment of the present disclosure further provides a liquid leakage treatment device for a liquid-cooled server.

[0079] Figure 7 Schematically shows a schematic diagram of the composition of a liquid leakage treatment device for a liquid-cooled server according to an embodiment of the present disclosure.

[0080] As Figure 7As shown in the figure, the liquid leakage treatment device may include an inlet pipe 410, an outlet pipe 420, a differential pressure sensing component 430, and a control device 440. Among them, the inlet pipe 410 is configured to be connected to the inlet of the liquid-cooled server, and the outlet pipe 420 is configured to be connected to the outlet of the liquid-cooled server. The differential pressure sensing component 430 is connected to the inlet pipe 410 and the outlet pipe 420, and is configured to sense the differential pressure between the inlet pipe 410 and the outlet pipe 420, and send an induction signal when the differential pressure between the inlet pipe 410 and the outlet pipe 420 is greater than the initial differential pressure. The control device 440 is connected to the switching device 450 of the liquid-cooled server, and is configured to control the power-off of the liquid-cooled server through the switching device 450 when receiving the induction signal.

[0081] For example, the control device 440 may be a triode control circuit or a relay protector. Alternatively, the control device 440 may be a control device that manages multiple liquid-cooled servers. For example, for a control server, the liquid leakage detection devices located in the same computer room or on the same floor can send the induction signal to the control server through wireless communication. After receiving the induction signal sent by the liquid leakage detection device, the control server can control the power-off of the corresponding liquid-cooled server.

[0082] According to an embodiment of the present disclosure, the differential pressure sensing component 430 is further configured to block the inlet pipe 410 when the differential pressure between the inlet pipe 410 and the outlet pipe 420 is greater than the initial differential pressure.

[0083] Figure 8 The structural schematic diagram of the liquid leakage treatment device according to an embodiment of the present disclosure is schematically shown.

[0084] As Figure 8 shown, according to an embodiment of the present disclosure, the differential pressure sensing component 430 may include a differential pressure membrane 431, a sliding rod 432, and a touch element 433. The differential pressure membrane 431 is disposed between the inlet pipe 410 and the outlet pipe 420, and deforms when the differential pressure between the inlet pipe 410 and the outlet pipe 420 is greater than the initial differential pressure. The sliding rod 432 is fixedly connected to the differential pressure membrane 431 and moves when the differential pressure membrane 431 deforms. The touch element 433 contacts the first end of the sliding rod 432 and sends an induction signal when the sliding rod 432 moves from the initial position to the first position.

[0085] According to an embodiment of the present disclosure, the differential pressure sensing component may further include a piston 438. The piston 438 is fixedly connected to the second end of the sliding rod 432, and is configured to block the inlet pipe 410 when the sliding rod 432 moves to the first position.

[0086] According to an embodiment of the present disclosure, the differential pressure sensing assembly further includes a blocking member 435 configured to limit the first end of the sliding rod 432 to the first side of the blocking member when the differential pressure between the water inlet pipe 410 and the water outlet pipe 420 is the initial differential pressure, so as to limit the sliding rod to the initial position, and limit the first end of the sliding rod to the second side of the blocking member after the sliding rod 432 moves and pushes open the blocking member.

[0087] According to an embodiment of the present disclosure, the differential pressure sensing assembly further includes a spring 436 connected between the blocking member and the fixed structure to provide a blocking force for the blocking member to counteract the acting force of the initial differential pressure between the water inlet pipe and the water outlet pipe on the differential pressure membrane.

[0088] According to an embodiment of the present disclosure, the differential pressure sensing assembly further includes a first magnetic member and a second magnetic member. The first magnetic member is disposed on the touch element 433, and the second magnetic member is disposed on the first end of the sliding rod 432. When the distance between the first magnetic member and the second magnetic member is less than a predetermined distance, the first magnetic member and the second magnetic member attract each other.

[0089] According to another embodiment of the present disclosure, the differential pressure sensing assembly may include a capacitive differential pressure sensor connected between the water inlet pipe and the water outlet pipe and configured to sense the differential pressure between the water inlet pipe and the water outlet pipe and issue a sensing signal when the differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure.

[0090] Specifically, for the water inlet pipe 410, the water outlet pipe 420 and the differential pressure sensing assembly 430 in the liquid leakage treatment device, reference may be made to Figures 1 to 6 and the description of the corresponding drawings above, which will not be repeated here.

[0091] The liquid leakage treatment device according to the embodiment of the present disclosure can eliminate the safety risks caused by liquid leakage, improve the operation reliability of the cold plate liquid cooling server, reduce the safety hazards of liquid leakage, promote the popularization and use of the liquid cooling server, and promote the improvement of the computer room construction density and the construction of green data centers. Moreover, liquid leakage can be detected in a timely manner, and thus measures can be taken in a timely manner. In addition, the liquid leakage treatment device according to the embodiment of the present disclosure has a small change in the deployment architecture of the existing device, and the internal packaging and the appearance structure are simple and beautiful, which is convenient for installation.

[0092] Another aspect of the embodiments of the present disclosure also provides a liquid cooling system. The liquid cooling system includes a liquid supply device, a liquid-cooled server, and a liquid leakage handling device. Among them, the liquid leakage handling device includes an inlet pipe, an outlet pipe, a differential pressure sensing component, and a control device. The inlet pipe is connected between the outlet of the liquid supply device and the inlet of the liquid-cooled server, and the outlet pipe is connected between the inlet of the liquid-cooled server and the inlet of the liquid supply device. The differential pressure sensing component is connected to the inlet pipe and the outlet pipe, and is configured to sense the differential pressure between the inlet pipe and the outlet pipe, and issue a sensing signal when the differential pressure between the inlet pipe and the outlet pipe is greater than the initial differential pressure. The control device is connected to the switching device of the liquid-cooled server, and is configured to control the liquid-cooled server to shut down through the switching device when receiving the sensing signal.

[0093] According to the embodiments of the present disclosure, a liquid leakage handling device can be set for each liquid-cooled server to detect and handle the liquid leakage problem of a single server, reducing the influence range of the liquid leakage and avoiding the technical problem that when detecting and handling the liquid leakage of a batch of servers, if one server leaks water, all the servers in this batch need to be isolated simultaneously, resulting in a relatively large influence range.

[0094] For example, the liquid supply device can be a device that provides coolant for the liquid-cooled server.

[0095] Specifically, for the liquid supply device, the liquid-cooled server, the inlet pipe, the outlet pipe, the differential pressure sensing component, and the control device, reference can be made to Figures 1 to 8 the description of the corresponding drawings above, which will not be elaborated here.

[0096] Another aspect of the present disclosure provides a liquid leakage handling method for a liquid-cooled server.

[0097] Figure 9 The flowchart of the liquid leakage handling method according to the embodiments of the present disclosure is schematically shown.

[0098] As Figure 9 shown, the method may include operations S510 to S530.

[0099] In operation S510, obtain the differential pressure information between the inlet pipe connected to the inlet of the liquid-cooled server and the outlet pipe connected to the outlet of the liquid-cooled server.

[0100] According to the embodiments of the present disclosure, obtaining the current differential pressure information between the inlet pipe and the outlet pipe may include: receiving a sensing signal from the differential pressure sensing component connected to the inlet pipe and the outlet pipe, and using the sensing signal as the differential pressure information.

[0101] For example, a differential pressure sensing component is connected between the water inlet pipe and the water outlet pipe. The differential pressure sensing component can sense the differential pressure between the water inlet pipe and the water outlet pipe and can send out a sensing signal. Among them, the differential pressure sensing component may refer to the first differential pressure sensing component composed of a differential pressure membrane, a sliding rod, a tactile element, etc. as described above. For details, please refer to Figure 4 and the relevant description. Or, the differential pressure sensing component may also refer to the capacitive differential pressure sensor as described above. For details, please refer to Figure 5 , Figure 6 and the relevant description.

[0102] Specifically, the connection relationship between the liquid-cooled server, the water inlet pipe, the water outlet pipe, and the differential pressure sensing component, as well as the specific composition of the differential pressure sensing component, can be found in Figures 1 to 8 , and the description of the corresponding drawings above. Details are not described herein again.

[0103] In operation S520, based on the differential pressure information, determine whether the current differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure.

[0104] According to an embodiment of the present disclosure, operation S520 may include: in response to receiving the differential pressure information from the differential pressure sensing component, determining that the current differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure.

[0105] For example, in the case where the differential pressure sensing component is the first differential pressure sensing component composed of a differential pressure membrane, a sliding rod, a tactile element, etc., once the sensing signal sent by the first differential pressure sensing component is received, it can be considered that the current differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure. Only when the differential pressure between the water inlet pipe and the water outlet pipe increases from the initial differential pressure, the differential pressure membrane will deform towards the water outlet side, and then the differential pressure membrane will drive the sliding rod to trigger the tactile element to send out a sensing signal. Therefore, once the sensing signal is received from the first differential pressure sensing component, it can be considered that the current differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure.

[0106] According to another embodiment of the present disclosure, the differential pressure information may include the value of the current differential pressure between the water inlet pipe and the water outlet pipe. Operation S520 may include: determining whether the value of the current differential pressure is greater than the initial differential pressure.

[0107] For example, when the differential pressure sensing component is a capacitive differential pressure sensor, the capacitive differential pressure sensor can not only send out a sensing signal when the differential pressure between the water inlet pipe and the water outlet pipe increases, but also detect the specific differential pressure value, that is, the sensing signal sent by the capacitive differential pressure sensor may include the value of the current differential pressure. Therefore, if the sensing signal sent by the capacitive differential pressure sensor is received, the current differential pressure value can be compared with the predetermined initial differential pressure value to determine whether the current differential pressure between the water inlet pipe and the water outlet pipe is greater than the initial differential pressure.

[0108] In operation S530, when the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference, the power supply of the liquid-cooled server is controlled to be turned off.

[0109] When the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference, it is considered that the liquid-cooled server has a liquid leakage. The liquid-cooled server can be immediately turned off to eliminate the safety risk caused by the liquid leakage.

[0110] According to an embodiment of the present disclosure, the liquid leakage handling method may further include: controlling the valve of the water inlet pipe to be closed when the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference.

[0111] For example, an electric valve can be provided on the water inlet pipe. When the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference, it is considered that the liquid-cooled server has a liquid leakage. The electric valve on the water inlet pipe can be immediately closed, blocking the water inlet channel, cutting off the water supply, and reducing the loss.

[0112] According to an embodiment of the present disclosure, the pressure difference between the inlet and outlet pipes of the liquid-cooled server can be obtained, and whether the liquid-cooled server has a liquid leakage can be determined by detecting the pressure difference between the inlet and outlet pipes. When a liquid leakage is detected, the liquid-cooled server can be controlled to be turned off. Therefore, the safety risk caused by the liquid leakage of the liquid-cooled server can be eliminated, the operation reliability of the liquid-cooled server can be improved, the safety hazard of the liquid leakage can be reduced, the popularization and use of the liquid-cooled server can be promoted, and the construction density of the computer room and the construction of the green data center can be advanced. Moreover, the pressure inside the liquid-cooled server is greater than the atmospheric pressure. Once the liquid-cooled server has a liquid leakage (for example, the liquid leakage caused by the rupture of the liquid circulation pipeline and its interface inside the liquid-cooled server), the pressure inside the liquid-cooled server will be released. Coupled with the loss of the liquid, the pressure difference between the inlet and outlet pipes will change more rapidly and significantly. The change in the pressure difference between the inlet and outlet pipes is more obvious than the change in the flow rate. Therefore, the liquid leakage can be detected in time and corresponding measures can be taken in time.

[0113] Another aspect of the present disclosure provides a liquid leakage handling device for a liquid-cooled server.

[0114] The device may include an acquisition module, a determination module, and a control module. Among them, the acquisition module is used to obtain the pressure difference information between the water inlet pipe connected to the water inlet of the liquid-cooled server and the water outlet pipe connected to the water outlet of the liquid-cooled server; the determination module is used to determine whether the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference based on the pressure difference information; the control module is used to control the power supply of the liquid-cooled server to be turned off when the current pressure difference between the water inlet pipe and the water outlet pipe is greater than the initial pressure difference.
