Description

Technical Field

[0001] The present application relates to the technical field of server cooling equipment, and in particular to a liquid cooling system connecting pipe, a server liquid cooling system and a server. Background Art

[0002] In server systems, as Internet business volume has grown rapidly, business computing volume and frequency have increased accordingly, which has increased the server's carrying pressure and the server's power consumption has also increased rapidly. This has led to the need to configure high-power chips during server operation, and the heat dissipation of high-power chips plays a vital role in the efficient operation of the chips.

[0003] In the related technologies, liquid cooling is an emerging cooling technology that uses the flow of liquid cooling medium to remove the heat from the heat-generating components, replacing the air heat exchange mode used in air cooling. Compared with air cooling, liquid cooling technology can better support the heat dissipation of high-power chips, keep the chips running at low temperatures, and extend their lifespan. Among them, the cold plate liquid cooling system usually uses liquid media to be pumped into the important high-heat dissipation components of the server such as the CPU ( Central Processing Unit , CPU), memory, hard disk, network card, etc. are placed on special heat sinks (i.e. cold plates or exchange plates). The heat sink is connected to high-heat components for heat conduction, and the liquid cooling medium flows through the heat sink in turn to take away the heat and reduce the system temperature.

[0004] However, in the cold plate liquid cooling system, the cooling medium is deionized water or ethylene glycol / propylene glycol aqueous solution. If the cooling medium and the cold plate material are not properly selected and maintained, corrosion may occur after long-term operation, resulting in leakage of the cooling medium. After the server detects a leakage in the system, it usually sends an alarm message or sends an alarm message and cuts off the power supply to the server. If the maintenance personnel do not discover it in time, the leakage will accumulate, causing corrosion damage to the server hardware at the least, and even causing a short circuit or burnout of the server at the worst. Summary of the invention

[0005] The present application provides a liquid cooling system connecting pipe, a server liquid cooling system and a server, so as to solve or improve the problem that the server liquid cooling system leaks, causing corrosion damage or short circuit and complete damage to the server.

[0006] In a first aspect, the present application provides a server liquid cooling system, comprising an inner tube and an outer tube;

[0007] Both ends of the inner tube are provided with joints, which are suitable for communicating with the interface with the first valve. The inner tube is provided with a liquid extraction pipe, which is suitable for communicating with a liquid extraction pump and is used for extracting and draining liquid from the inner tube.

[0008] The outer tube is sleeved on the outside of the inner tube and is spaced apart from the inner tube. The end of the outer tube can be sleeved, and at least a part of the interface connected to the joint is connected to the outer tube. An air extraction pipe is connected to the outer tube, and the air extraction pipe is suitable for connecting to an air extraction pump to extract and exhaust the outer tube.

[0009] Wherein, both the inner tube and the outer tube can be deformed under negative pressure, and two joints of the inner tube are provided with leakage detection components, which are located inside the outer tube and are suitable for connection with the control module.

[0010] In this embodiment, the joints at both ends of the inner tube are connected to the interface with the first valve, and a leakage detection component is provided at the joint of the inner tube, so that when leakage of the inner tube is detected, the first valves located at both ends of the inner tube can be closed to prevent further injection of liquid cooling medium into the inner tube; at the same time, an outer tube is sleeved on the outside of the inner tube for conveying the liquid cooling medium, and the interfaces connected to the two ends of the inner tube can be at least partially encircled by the outer tube, and both the inner tube and the outer tube can be deformed under negative pressure, and an exhaust pipe is provided on the outer tube to collect and discharge the liquid cooling medium leaked between the outer tube and the inner tube, and a liquid extraction pipe is provided on the inner tube to discharge the liquid cooling medium in the inner tube, so that there is no liquid cooling medium in the inner tube and the outer tube, or the residual liquid cooling medium will not leak into the external environment, thereby avoiding leakage and avoiding corrosion damage or short circuit damage to the server.

[0011] In an optional embodiment, the leakage detection component includes a first conductive ring and a second conductive ring, the first conductive ring and the second conductive ring are both coaxially arranged with the inner tube and spaced apart along the axial direction of the inner tube, the first conductive ring and the second conductive ring are both insulated from the inner tube, the outer tube and the joint, the first conductive ring and the second conductive ring are suitable for connecting to a control module, and the first conductive ring and the second conductive ring can be short-circuited by leakage, so that the control module obtains a leakage signal.

[0012] In this embodiment, a leakage detection component includes a first conductive ring and a second conductive ring, and the two are spaced apart. The first conductive ring and the second conductive ring are insulated from the inner tube, the outer tube and the joint, so that there is no electricity between the first conductive ring and the second conductive ring. A detection signal is applied to the first conductive ring and the second conductive ring through a control module. When leakage enters between the first conductive ring and the second conductive ring, the leakage can connect the first conductive ring and the second conductive ring, thereby changing the detection signal applied by the control module to obtain a leakage signal, thereby judging leakage. The structure is simple, easy to manufacture and low in cost.

[0013] In an optional implementation, the joint is located between the first conductive ring and the second conductive ring, and an interface connected to the joint can be accommodated between the first conductive ring and the second conductive ring.

[0014] In this embodiment, by arranging the connected connector and interface between the first conductive ring and the second conductive ring, leakage at the connector and interface, as well as leakage in the inner tube can be monitored, thereby improving the comprehensiveness and accuracy of leakage monitoring and further reducing the risk of damage to the server caused by leakage.

[0017] In an optional embodiment, the leakage detection component also includes a third conductive ring, which is coaxially sleeved on the inner tube, and the first conductive ring is located between the second conductive ring and the third conductive ring; wherein the third conductive ring is suitable for connecting to a control module, and the first conductive ring and the third conductive ring can be short-circuited through leakage, so that the control module obtains a leakage signal.

[0018] In this embodiment, the third conductive ring is coaxially sleeved on the inner tube, and the first conductive ring is located between the second conductive ring and the third conductive ring. When liquid leaks, it enters between the first conductive ring and the third conductive ring and causes a short circuit between the two. The detection signal applied by the control module between the first conductive ring and the third conductive ring changes first, thereby obtaining a leakage signal, and it can be determined that the cause of the leakage is leakage from the inner tube. When it is detected that the detection signal applied by the control module between the first conductive ring and the second conductive ring changes first, it can be determined that there is leakage at the joint of the inner tube, which is convenient for accurately determining the leakage location and improving maintenance efficiency.

[0019] In an optional embodiment, the outer tube can be sealingly sleeved on the interface.

[0022] In this embodiment, elastic sleeves are provided at both ends of the outer tube, and sealing contact with the interface is achieved through the elasticity of the elastic sleeves. The solution is simple and has a good sealing effect.

[0064] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0065] In the related technology, liquid cooling is an emerging cooling technology, which uses the flow of liquid cooling medium to take away the heat of the heating components, replacing the air heat exchange mode used in air cooling heat exchange. Compared with air cooling, liquid cooling technology can better support the heat dissipation of high-power chips, keep the chips running at low temperatures, and extend their lifespan. Among them, the cold plate liquid cooling system usually uses liquid medium to be pumped into the special heat sink (ie cold plate or exchange plate) of important high-heat dissipation components of the server such as CPU, memory, hard disk, network card, etc. by plastic or rubber pipes. The heat sink conducts heat by connecting to the high-heat components, and the liquid cooling medium flows through the heat sink in turn to take away heat and lower the system temperature.

[0066] However, in the cold plate liquid cooling system, the cooling medium is deionized water or ethylene glycol / propylene glycol aqueous solution. If the cooling medium and the cold plate material are not properly selected and maintained, corrosion may occur after long-term operation, resulting in cooling medium leakage. After the server detects that the system has leaked, Figure 1 As shown, an alarm message is usually issued or an alarm message is issued and the power supply to the server is cut off. If the maintenance personnel do not discover it in time, the leakage will accumulate, causing corrosion damage to the server hardware at the least, and causing a short circuit or burnout of the server at the worst.

[0067] To solve the above problems, the present application provides a liquid cooling system connecting pipe, a server liquid cooling system and a server, so as to solve or improve the problem of liquid leakage in the server liquid cooling system, causing damage or complete destruction of the server.

[0068] Combine the following Figures 2 to 10 , describing an embodiment of the present application.

[0069] According to an embodiment of the present application, on the one hand, a liquid cooling system connecting pipe 1 is provided, such as Figure 2 As shown, it includes an inner tube 11 and an outer tube 12, and the specific scheme is as follows.

[0070] like Figure 2 As shown, joints 111 are provided at both ends of the inner tube 11, which are suitable for communicating with the interface 23 having a first valve 231. A liquid extraction pipe 112 is provided on the inner tube 11, and the liquid extraction pipe 112 is suitable for communicating with the liquid extraction pump 25, and is used for extracting and draining liquid from the inner tube 11;

[0071] like Figure 2As shown, the outer tube 12 is sleeved on the outside of the inner tube 11 and is spaced apart from the inner tube 11. The end of the outer tube 12 can be sleeved, and at least a part of the interface 23 connected to the joint 111, specifically, the liquid extraction tube 112 seals and passes through the outer tube 12; the outer tube 12 is connected with an air extraction tube 121, which is suitable for being connected with the air extraction pump 24, and is used to extract and exhaust the outer tube 12;

[0072] Among them, both the inner tube 11 and the outer tube 12 can be deformed under negative pressure. Specifically, the inner tube 11 is a TPV hose or a PVC hose, and the outer tube 12 is any one of a PVC hose, a TPV hose and a silicone hose. The two joints 111 of the inner tube 11 are provided with leakage detection components 13. The leakage detection component 13 is located in the outer tube 12 and is suitable for connecting with the control module 26.

[0073] Specifically, the connector 111 and the interface 23 are two parts of a quick-tight connector commonly used on the market, and the two parts are screwed together by threads. The specific size specifications can be selected and adjusted according to the requirements of use.

[0074] It should be noted that the end of the outer tube 12 can be looped around at least a portion of the interface 23 connected to the connector 111, which means that the end of the outer tube 12 can be ring-shaped to at least cover a portion of the interface 23 close to the connector 111, that is, it can cover a portion or all of it.

[0075] In this embodiment, if Figure 2 As shown, the joints 111 at both ends of the inner tube 11 are connected to the interface 23 with the first valve 231, and a leakage detection component 13 is provided at the joint 111 of the inner tube 11, so that when leakage of the inner tube 11 is detected, the first valves 231 located at both ends of the inner tube 11 can be closed to prevent the liquid cooling medium from being continuously injected into the inner tube 11; at the same time, the outer tube 12 is sleeved on the outer side of the inner tube 11 for conveying the liquid cooling medium, and the interfaces 23 connected to both ends of the inner tube 11 can be closed by the outer tube 12 At least a portion of the annular sleeve, the inner tube 11 and the outer tube 12 can be deformed under negative pressure, the outer tube 12 is provided with an exhaust pipe 121 to collect and discharge the liquid cooling medium leaked between the outer tube 12 and the inner tube 11, and the inner tube 11 is provided with a liquid extraction pipe 112 to discharge the liquid cooling medium in the inner tube 11, so that there is no liquid cooling medium in the inner tube 11 and the outer tube 12, or the residual liquid cooling medium will not leak into the external environment, thereby avoiding leakage, and avoiding corrosion damage or short circuit damage to the server.

[0076] In one embodiment, Figure 2 and Figure 8As shown, the leakage detection component 13 includes a first conductive ring 131 and a second conductive ring 132. Specifically, the first conductive ring 131 and the second conductive ring 132 are both metal rings, such as copper rings, iron rings, etc., preferably copper rings, which have strong corrosion resistance and oxidation resistance; the first conductive ring 131 and the second conductive ring 132 are both coaxially arranged with the inner tube 11, and are spaced apart along the axial direction of the inner tube 11. The first conductive ring 131 and the second conductive ring 132 are insulated from the inner tube 11, the outer tube 12 and the joint 111. The first conductive ring 131 and the second conductive ring 132 are suitable for connecting to the control module 26 through wires. The first conductive ring 131 and the second conductive ring 132 can be connected through leakage to cause a short circuit, so that the control module 26 obtains a leakage signal.

[0077] It needs to be explained that the first conductive ring 131 and the second conductive ring 132 are insulated from the inner tube 11, the outer tube 12 and the joint 111 in order to keep the first conductive ring 131 and the second conductive ring 132 from being energized. Of course, if the joint 111, the interface 23, the inner tube 11 and the outer tube 12 are all made of insulating materials, no insulation treatment is required. Usually, the joint 111, the interface 23, the inner tube 11 and the outer tube 12 are also made of insulating materials and no insulation treatment is required. If necessary, insulating material is added for isolation. The insulating material may be insulating glue, etc.

[0078] It should be noted that the first conductive ring 131 can be fixed on the joint 111 or the inner tube 11, and correspondingly, the first conductive ring 131 is spaced apart from the outer tube 12, so that the leaked liquid can be pumped out by the vacuum pump 24; of course, the first conductive ring 131 can also be fixed on the inner wall surface of the outer tube 12, and correspondingly, the first conductive ring 131 is spaced apart from the joint 111 or the inner tube 11, so that the leaked liquid can be pumped out by the vacuum pump 24; the second conductive ring 132 can be fixed on the joint 111 or the interface 23, and correspondingly, the second conductive ring 132 is spaced apart from the outer tube 12, so that the leaked liquid can be pumped out by the vacuum pump 24; of course, the second conductive ring 132 can also be fixed on the inner wall surface of the outer tube 12, and correspondingly, the second conductive ring 132 is spaced apart from the joint 111 or the interface 23, so that the leaked liquid can be pumped out by the vacuum pump 24.

[0079] In this embodiment, if Figure 2As shown, the leakage detection component 13 includes a first conductive ring 131 and a second conductive ring 132, and the two are arranged at an interval. The first conductive ring 131 and the second conductive ring 132 are insulated from the inner tube 11, the outer tube 12 and the joint 111, so that there is no electricity between the first conductive ring 131 and the second conductive ring 132. A detection signal is applied to the first conductive ring 131 and the second conductive ring 132 through the control module 26. When leakage enters between the first conductive ring 131 and the second conductive ring 132, the leakage can connect the first conductive ring 131 and the second conductive ring 132 and short-circuit them, thereby changing the detection signal applied by the control module 26 to obtain a leakage signal, thereby judging leakage. The structure is simple, easy to manufacture, and low cost.

[0080] In one embodiment, Figure 2 As shown, the connector 111 is located between the first conductive ring 131 and the second conductive ring 132 , and the interface 23 connected to the connector 111 can be accommodated between the first conductive ring 131 and the second conductive ring 132 .

[0081] It should be noted that the connector 111 is located between the first conductive ring 131 and the second conductive ring 132, and the interface 23 connected to the connector 111 can be accommodated between the first conductive ring 131 and the second conductive ring 132. This is mainly to ensure that the matching gap between the interface 23 and the connector 111 is located between the first conductive ring 131 and the second conductive ring 132. When leakage occurs between the interface 23 and the connector 111, the leakage detection component 13 can monitor the leakage signal in the first time, thereby reducing the risk of leakage to the external environment.

[0082] In this embodiment, if Figure 2 As shown, by arranging the connected connector 111 and the interface 23 between the first conductive ring 131 and the second conductive ring 132, leakage at the joint between the connector 111 and the interface 23, as well as leakage of the inner tube 11 can be monitored, thereby improving the comprehensiveness and accuracy of leakage monitoring and further reducing the risk of damage to the server caused by leakage.

[0083] In one embodiment, Figure 2 and Figure 3 As shown, the first conductive ring 131 is arranged on the outer surface of the inner tube 11, and the second conductive ring 132 is connected to the joint 111 through the insulating frame 134, and can be sleeved on the outer surface of the interface 23. Specifically, the insulating frame 134 can be a plastic frame, such as Figure 3 As shown, a hollow portion 1341 is provided on the insulating frame 134 to facilitate the contact of the leaked liquid with the first conductive ring 131 and the second conductive ring 132 to generate a leaked liquid signal.

[0084] It should be noted that if Figure 3As shown, a hollow portion 1341 is provided on the insulating frame 134, which is mainly for facilitating the leakage of liquid to pass through, to connect the first conductive ring 131 and the second conductive ring 132, and to generate a leakage signal. As for the specific structure of the insulating frame 134, it can be a plurality of connecting rods arranged circumferentially at intervals with the joint 111. Of course, the connecting rod can be an integrally formed structure with the joint 111, and a fixing portion (not shown in the figure) is provided on one end of the connecting rod connected to the second conductive ring 132. The fixing portion is specifically a fixing groove, which can install the second conductive ring 132 in the fixing groove by its own deformation. Of course, a notch is provided on the wall surface of the fixing groove to facilitate the contact between the leakage and the second conductive ring 132.

[0085] In this embodiment, if Figure 2 and Figure 3 As shown, the second conductive ring 132 is connected to the joint 111 through the insulating frame 134 and can be sleeved on the interface 23, and a hollow portion 1341 is provided on the insulating frame 134 to facilitate the leakage of liquid and the electrical contact with the first conductive ring 131 and the second conductive ring 132. The first conductive ring 131 and the second conductive ring 132 can be integrated on the liquid cooling system connecting pipe 1 to improve its applicability.

[0086] In one embodiment, Figure 2 As shown, the leakage detection component 13 also includes a third conductive ring 133. Specifically, the third conductive ring 133 is a metal ring, such as a copper ring, an iron ring, etc., preferably a copper ring, which has strong corrosion resistance and oxidation resistance. The third conductive ring 133 is coaxially sleeved on the inner tube 11, and the first conductive ring 131 is located between the second conductive ring 132 and the third conductive ring 133. The third conductive ring 133 is suitable for connecting with the control module 26, and the first conductive ring 131 and the third conductive ring 133 can be connected through leakage to cause a short circuit, so that the control module 26 obtains a leakage signal.

[0087] It should be noted that the third conductive ring 133 is fixed on the inner tube 11 , and the third conductive ring 133 is spaced apart from the inner wall surface of the outer tube 12 , so that the leaked liquid can be discharged through the vacuum pump 24 .

[0088] In this embodiment, if Figure 2As shown, the third conductive ring 133 is coaxially sleeved on the inner tube 11, and the first conductive ring 131 is located between the second conductive ring 132 and the third conductive ring 133. When the leakage enters between the first conductive ring 131 and the third conductive ring 133, and the two are short-circuited, the detection signal applied by the control module 26 between the first conductive ring 131 and the third conductive ring 133 changes first, thereby obtaining a leakage signal, and it can be determined that the cause of the leakage is leakage of the inner tube 11. When it is detected that the detection signal applied by the control module 26 between the first conductive ring 131 and the second conductive ring 132 changes first, it can be determined that there is leakage at the joint 111 of the inner tube 11, which is convenient for accurately determining the leakage position and improving maintenance efficiency.

[0089] In one embodiment, Figure 2 As shown, the outer tube 12 can be placed sealingly on the connection 23 .

[0090] It should be noted that the sealing sleeve of the outer tube 12 is arranged on the interface 23, which means that the end of the outer tube 12 is in sealing contact with the interface 23, and can maintain sealing under a certain pressure of the vacuum pump 24, and can also prevent the leakage from overflowing into the external environment in the case of leakage with a certain pressure.

[0091] In this embodiment, if Figure 2 As shown, by sealing the outer tube 12 on the interface 23, it is possible to prevent liquid from leaking out from the end of the outer tube 12, further reducing the risk of liquid leaking into the external environment and causing damage to the server.

[0092] In one embodiment, Figure 2 As shown, elastic sleeves 122 are provided at both ends of the outer tube 12 , and the elastic sleeves 122 are sealedly sleeved with the interface 23 .

[0093] It should be noted that the elastic sleeve 122 can be a silicone sleeve, which is elastically pressed onto the interface 23 to achieve a sealed connection. During the connection between the connector 111 and the interface 23, the elastic sleeve 122 can be folded to the peripheral position through its elastic deformation ability to expose the connector 111. After the connection between the connector 111 and the interface 23 is completed, the elastic sleeve 122 is folded again and reset, and crimped onto the interface 23.

[0094] In this embodiment, elastic sleeves 122 are provided at both ends of the outer tube 12 , and the elastic sleeves 122 are in sealing contact with the interface 23 through the elasticity of the elastic sleeves 122 . The solution is simple and has a good sealing effect.

[0095] In some embodiments not shown, the outer tube 12 may also be sealed and connected to the interface 23 by means of heating and shaping. In the specific process, a model with a heating function may be used for heating and clamping.

[0096] In one embodiment, Figure 2 and Figure 4 As shown, a gas channel 1221 is provided at the sealed portion of the outer tube 12 and the interface 23, and one end of the gas channel 1221 is oriented toward the second conductive ring 132 in the tangential direction of the outer tube 12, and the other end of the gas channel 1221 is connected to the outside world, so that when the vacuum pump 24 is used to evacuate the leaked liquid in the outer tube 12, the outside air can enter the outer tube 12 through the gas channel 1221 to form a spiral airflow, thereby accelerating the discharge of the leaked liquid.

[0097] Further, such as Figure 4 As shown, the gas channel 1221 is spirally arranged on the surface of the outer tube 12 in contact with the interface 23, thereby forming a spiral seal, which can reduce the risk of liquid leakage to the outside through the gas channel 1221 when the vacuum pump 24 is not started.

[0098] In a second aspect, the present application also provides a server liquid cooling system 2, such as Figure 6 As shown, it includes a heat exchanger 21, a refrigeration assembly 22 and a liquid cooling system connecting pipe 1 in any one embodiment of the first aspect, wherein the form of the heat exchanger 21 can be selected and adjusted according to the type of the heating element 31, such as selecting different types of heat exchangers 21 for memory bars and CPUs;

[0099] like Figure 6 As shown, a plurality of heat exchange plates 21 are provided, each used for heat exchange with a heating element 31 in the server. The liquid inlet and the liquid outlet of the heat exchange plate 21 are both provided with an interface 23 having a first valve 231. Specifically, the first valve 231 is an electrically controlled valve.

[0100] like Figure 2 As shown, the refrigeration component 22 is used to cool the circulating cooling medium, and an interface 23 with a first valve 231 is provided in the liquid inlet and the liquid outlet of the refrigeration component 22.

[0101] Any two connected components in the refrigeration assembly 22 and the plurality of heat exchange plates 21 are connected via the liquid cooling system connecting pipe 1 ; wherein the first valve 231 is suitable for being electrically connected to the control module 26 .

[0102] It should be noted that if Figure 6As shown, multiple heat exchange plates 21 can form multiple cooling circuits in parallel to cool the heating elements 31 on multiple mainboards 3 respectively. Multiple parallel branch circuits can also be set in one cooling circuit to cool different types of heating elements 31 on the mainboard 3. For example, if multiple CPUs and multiple storage hard disks are set on the mainboard 3, parallel branch circuits can be set on the mainboard 3, one branch circuit is used to cool the multiple CPUs, and the other branch circuit is used to cool the multiple storage hard disks.

[0103] In this embodiment, a first valve 231 is provided in the liquid inlet and the liquid outlet of the heat exchange plate 21 and the refrigeration component 22, and the components that are interconnected are connected through the liquid cooling system connecting pipe 1. The technical effect is the same as that of the liquid cooling system connecting pipe 1, and will not be repeated here.

[0104] In one embodiment, Figure 7 As shown, the server liquid cooling system 2 also includes an air pump 24, a liquid pump 25 and a control module 26; the air pump 24 is connected to the air pump 121 on each outer tube 12, and each air pump 121 is provided with a second valve 1211; the liquid pump 25 is connected to the liquid pump 112 on each inner tube 11, and each liquid pump 112 is provided with a third valve 1121; the control module 26 is electrically connected to the air pump 24, the liquid pump 25, multiple first valves 231, multiple second valves 1211 and multiple third valves 1121, wherein the second valve 1211 and the third valve 1121 are both electrically controlled valves.

[0105] It is worth noting that the air pump 24 and the liquid pump 25 can be designed as an integrated device, that is, a multifunctional pump is provided that can pump both air and liquid to be connected to both the air pumping pipe 121 and the liquid pumping pipe 112.

[0106] Specifically, the control module 26 is an MCU ( Microcontroller Unit , microcontroller) module.

[0107] In this embodiment, if Figure 7 As shown, by setting a second valve 1211 on each air extraction pipe 121 on each outer tube 12, and then connecting them to the air extraction pump 24; by setting a third valve 1121 on each liquid extraction pipe 112 on each inner tube 11, and then connecting them to the liquid extraction pump 25, and the liquid extraction pump 25, multiple first valves 231, multiple second valves 1211 and multiple third valves 1121 are all electrically connected to the control module 26, and the control module 26 controls the first valve 231, the second valve 1211, the third valve 1121, the air extraction pump 24 and the liquid extraction pump 25 to work together to extract and discharge the leaked liquid and the liquid cooling medium in the inner tube 11. The solution is simple and easy to operate.

[0108] In one embodiment, Figure 6 As shown, among the refrigeration component 22 and the multiple heat exchange plates 21, any two connected components are connected through multiple parallel liquid cooling system connecting pipes 1. Accordingly, there are multiple liquid inlets and outlets on the refrigeration component 22, and there are multiple liquid inlets and outlets on the heat exchange plate 21.

[0109] It needs to be explained that Figure 6 As shown, among the refrigeration assembly 22 and the multiple heat exchange plates 21, any two connected components are connected through multiple parallel liquid cooling system connecting pipes 1, wherein the number of the multiple parallel liquid cooling system connecting pipes 1 can be 2 to 4, preferably 2; of course, the number of the liquid cooling system connecting pipes 1 can also be selected and set according to the flow requirement of the liquid cooling medium.

[0110] In this embodiment, if Figure 6 and Fig. 9 As shown, any two connected components of the refrigeration component 22 and the multiple heat exchanger plates 21 are connected through multiple parallel liquid cooling system connecting pipes 1, and the heat exchanger plates 21 and the refrigeration component 22 are provided with liquid inlets and liquid outlets corresponding to the multiple parallel liquid cooling system connecting pipes 1, so that when any one of the multiple parallel liquid cooling system connecting pipes 1 leaks, the liquid cooling medium can continue to circulate through the other liquid cooling system connecting pipes 1, so that maintenance can be carried out without shutting down the running server.

[0111] In one embodiment, Figure 5 As shown, a liquid inlet chamber 211, a plurality of circulation channels 212 and a liquid outlet chamber 213 are provided in the heat exchange plate 21. Both ends of the plurality of circulation channels 212 are respectively connected to the liquid inlet chamber 211 and the liquid outlet chamber 213. The liquid inlet of the heat exchange plate 21 is connected to the liquid inlet chamber 211, and the liquid outlet of the heat exchange plate 21 is connected to the liquid outlet chamber 213.

[0112] Specifically, the shapes of the liquid inlet chamber 211 and the liquid outlet chamber 213 can be designed according to the positions of the input ports and the output ports of the multiple circulation channels 212. Generally speaking, the liquid inlet chamber 211 and the liquid outlet chamber 213 are rectangular; the cross-section of the circulation channel 212 can be set according to needs and can be circular or square.

[0113] In this embodiment, if Figure 5As shown, by setting a liquid inlet chamber 211 and a liquid outlet chamber 213 in the heat exchange plate 21, they are respectively connected with the two ends of multiple circulation channels 212, so that the liquid inlet chamber 211 can redistribute the flow of the liquid cooling medium input through multiple parallel liquid cooling system connecting pipes 1, thereby improving the cooling uniformity of the heat exchange plate 21 on the heating element 31; the liquid outlet chamber 213 can converge the liquid cooling medium in multiple circulation channels 212 and redistribute it. Even if there is a liquid cooling system connecting pipe 1 leaking downstream, the liquid cooling medium can be evenly diverted, thereby improving the smoothness of the system liquid cooling medium circulation.

Specifically, the display screen 261 can be a computer screen, an LED screen, etc., or any type of screen as long as it can display the information of the leakage location and leakage duration; specifically, Fig.10 P12 in the figure represents the serial number of the liquid cooling system connecting pipe 1, and 3.52s represents the leakage duration.

[0115] In this embodiment, a display screen 261 is provided to display the leakage location and leakage duration, so that maintenance personnel can quickly find the leakage location and perform maintenance, thereby improving maintenance efficiency.

[0116] In one embodiment, Fig.10 As shown, a reset switch 262 and a manual switch are provided on the control module 26.

[0117] Specifically, the reset switch 262 may be a virtual button integrated on the touch-type display screen 261 , or may be a physical button in the control module 26 , etc.

[0118] In this embodiment, the reset switch 262 can reset the first valve 231, the second valve 1211, the third valve 1121, the air pump 24 and the liquid pump 25, so that maintenance personnel can perform quick testing and liquid cooling operation after repairing the leaking part.

[0119] In one embodiment, Fig.10As shown, the control module 26 can monitor the leakage signal fed back by the leakage detection component 13 in real time; the control module 26 controls the first valve 231 located at both ends of the leaking liquid cooling system connecting pipe 1 to close according to the leakage signal; and controls the vacuum pump 24 to work, and the second valve 1211 located on the leaking liquid cooling system connecting pipe 1 to open, so as to extract the leaked liquid between the outer tube 12; at the same time, the control module 26 controls the liquid extraction pump 25 to work, and the third valve 1121 located on the leaking liquid cooling system connecting pipe 1 to open, so as to extract the liquid cooling medium in the inner tube 11, thereby disabling the leaking liquid cooling system connecting pipe 1.

[0120] In this embodiment, the control module 26 is used to simultaneously control the first valve 231 to be closed, the air pump 24 to be opened, the second valve 1211 to be opened, the liquid pump 25 to be opened, and the third valve 1121 to be opened, so as to timely drain the leaked liquid and the liquid cooling medium in the inner tube 11 to prevent leakage to the external environment and reduce the risk of server damage.

[0122] Specifically, the server may be any one of a mail server, a database server, an application server, a Web server, a virtualization server, a cloud computing server, a website server, and a dedicated server.

[0123] In this embodiment, because the server includes the server liquid cooling system 2, it has the same effect as the server liquid cooling system 2 and is not described in detail here.

[0124] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations are all within the scope defined by the appended claims.
