Description

Technical Field

[0001] The present invention relates to the technical field of data center cooling, and in particular to a liquid leakage prevention device and a liquid cooling cabinet. Background Art

[0002] With the continuous development of artificial intelligence and the demand for energy conservation in data centers, liquid cooling is becoming increasingly important in data center heat dissipation. However, because the supply and return pipes between liquid cooling cabinets and data center equipment are currently not protected before or during connection, damaged pipe joints or improper connection procedures can easily lead to liquid leakage, causing damage to the cabinets and data center equipment. Summary of the Invention

[0003] According to one aspect of the present disclosure, a liquid leakage prevention device is provided for use in a liquid-cooling cabinet, the liquid-cooling cabinet having a water supply pipe and a water return pipe. The device includes a liquid collecting pipe and a liquid collecting structure, the liquid collecting pipe being in communication with the liquid collecting structure, the liquid collecting structure having a first surface and a second surface opposite to each other, the first surface being adjacent to the liquid-cooling cabinet, and the liquid collecting structure further having a first through hole and a second through hole extending along the first surface and the second surface.

[0004] The device also includes at least two movable shielding components and at least two push-type driving parts. The first through hole is opposite to the joint of the water supply pipe, and the second through hole is opposite to the joint of the return pipe. Each of the movable shielding components is arranged in the corresponding first through hole and the second through hole. Each of the push-type driving parts is arranged on the liquid collection structure. Part of the push-type driving part extends out of the second surface. The push-type driving part is transmission-connected to the movable shielding component.

[0005] According to another aspect of the present disclosure, a liquid cooling cabinet is provided, comprising at least one liquid leakage prevention device and a manifold provided by an exemplary embodiment of the present disclosure, wherein the liquid leakage prevention device is provided on the manifold.

[0006] In one or more technical solutions provided by the embodiments of the present disclosure, a liquid leakage prevention device includes a liquid collecting pipe and a liquid collecting structure, wherein the liquid collecting pipe and the liquid collecting structure are connected. At the same time, the liquid leakage prevention device also includes at least two movable shielding components, the liquid collecting structure having a first through hole opposite to the joint of the water supply pipe and a second through hole opposite to the joint of the return pipe, and each movable shielding component is respectively arranged in the corresponding first through hole and second through hole to shield the first through hole and the second through hole. In this case, before the water supply pipe joint and the return pipe joint are connected to the data center equipment and the liquid cooling cabinet, because the water supply pipe joint is shielded by the movable shielding plate located in the first through hole and the return pipe joint is shielded by the movable shielding plate located in the second through hole, when the water supply pipe joint and the return pipe joint are damaged and splashing occurs, the liquid splashes onto the movable shielding plate, is collected by the liquid collecting structure, and then flows out through the liquid collecting pipe, thereby preventing the splashing liquid from damaging the equipment and liquid cooling cabinet in the data center.

[0007] The anti-leakage device further includes at least two push-type drive members, which are in transmission connection with the movable shielding assembly. When the water supply and return pipe joints on the data center equipment are connected to the water supply and return pipe joints of the liquid cooling cabinet, the push-type drive member is pressed by the data center equipment near the liquid cooling cabinet, and the movable shielding assembly is controlled to move away, exposing the first through hole and the second through hole, so as to facilitate the connection of the water supply and return pipe joints on the data center equipment with the water supply and return pipe joints of the liquid cooling cabinet. At this time, if the joint leaks, since the joint on the data center equipment is a female connector, the leaked liquid will splash toward the liquid cooling cabinet under the blocking effect of the female connector, be collected by the liquid collecting structure, and then flow out through the liquid collecting pipe, thereby preventing the splashing liquid from damaging the equipment and liquid cooling cabinet in the data center and preventing the liquid from damaging the circuit.

[0026] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure.

[0029] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0030] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0031] With the increasing demand for energy efficiency in data centers and the continued development of artificial intelligence, the power of servers and chips continues to grow, generating more heat during operation. However, traditional air cooling methods are unable to meet the current data center heat dissipation needs, and liquid cooling is gradually becoming the main focus. Currently, cold plate cooling is one of the main development directions, combining cost and performance advantages.

[0032] Cold plate liquid cooling cabinets use cold plates mounted on the server's main heat-generating components to cool the components. Compared to traditional air-cooled cabinets, liquid-cooled servers require pre-installed cooling water supply and return lines and the addition of cold plates. Between the cold plate liquid cooling cabinet and the server, there are pipe connectors for cooling water, power supply, and network connectivity. The cooling water supply and return lines can be connected via quick-connect connectors, but these connectors must be manually connected during server installation. Because the current cold plate liquid cooling cabinet's supply and return pipe connections lack protective measures, the quick-connect connectors are susceptible to leaks. For example, before the cold plate liquid cooling cabinet is connected to the server's cooling water lines, the quick-connect connectors at the cooling water supply and return pipe connections lack leak-proof protection. If the quick-connect connectors are damaged, splashing can occur, damaging the server's systems. Liquid leakage can also occur during the insertion and removal of the quick-connect connectors. Therefore, the current research focus is on how to set up protective measures before and during the connection between the cold plate liquid cooling cabinet and the server cooling water supply and return pipes to prevent safety hazards caused by leakage at the joints.

[0033] In order to overcome the above problems, an exemplary embodiment of the present disclosure provides a liquid leakage prevention device, which can be installed on a liquid cooling cabinet. The liquid collecting structure of the liquid leakage prevention device cooperates with the liquid collecting pipe to collect the cooling liquid leaked at the joint, thereby preventing the cooling liquid from splashing and damaging the equipment and liquid cooling cabinets in the data center.

[0034] Figure 1 The schematic diagram shows the structure of the installation part of the water supply pipe and return pipe of the liquid cooling cabinet provided by an exemplary embodiment of the present disclosure. Figure 1 .like Figure 1As shown, the anti-leakage device 100 provided by the exemplary embodiment of the present disclosure is used in a liquid cooling cabinet, which has a water supply pipeline 110 and a return pipeline 120. The anti-leakage device 100 may include a liquid collecting pipe 101 and a liquid collecting structure 102, wherein the liquid collecting pipe 101 is connected to the liquid collecting structure 102 so that the leaked liquid collected by the liquid collecting structure 102 can be discharged to the water collecting tray (not shown in the figure) below the liquid cooling cabinet via the liquid collecting pipe 101. Specifically, the number of liquid collecting structures 102 included in the anti-leakage device can be set according to the number of equipment in the data center. When the number of equipment in the data center is multiple, the number of liquid collecting structures 102 included in the anti-leakage device is multiple, and the arrangement direction of the multiple liquid collecting structures 102 is the same as the extension direction of the water supply pipeline 110 and the return pipeline 120, and the extension direction of the liquid collecting pipe 101 is the same as the extension direction of the water supply pipeline 110 and the return pipeline 120. For example, when the water supply pipe 110 and the return pipe 120 are positioned vertically, the liquid collecting pipe 101 is also positioned vertically. The liquid collecting pipe 101 has an opening that matches the liquid collecting structure 102, which is used to collect leaked liquid collected by the liquid collecting structure 102 and direct the collected leaked liquid into a water collection tray. The liquid collecting structure 102 has opposing first and second surfaces 1021, 1022. The first surface 1021 is positioned adjacent to the liquid cooling cabinet. When the server is connected to the liquid cooling cabinet, the second surface 1022 is positioned adjacent to the server. The liquid collecting structure 102 also has first and second through-holes 1023, 1024 extending along the first and second surfaces 1021, 1022. It should be understood that the size of the first through hole 1023 and the second through hole 1024 here can be designed according to the water supply pipe joint (not shown in the figure) and the return pipe joint (not shown in the figure) of the data center equipment, as well as the water supply pipe joint (not shown in the figure) and the return pipe joint (not shown in the figure) of the liquid cooling cabinet, and no limitation is made here.

[0035] Figure 2 The schematic diagram shows the structure of the installation part of the water supply pipe and return pipe of the liquid cooling cabinet provided by an exemplary embodiment of the present disclosure. Figure 2 .like Figure 1 and Figure 2As shown, the above-mentioned liquid leakage prevention device 100 also includes at least two movable shielding components 103 and at least two push-type driving members 104. The first through hole 1023 is opposite to the joint of the water supply pipe 110, and the second through hole 1024 is opposite to the joint of the return pipe 120. It should be understood that the water supply pipe here refers to the water supply pipe of the liquid cooling cabinet and the water supply pipe of the equipment in the data center connected to the liquid cooling cabinet, and the return pipe here refers to the return pipe of the liquid cooling cabinet and the return pipe of the equipment in the data center connected to the liquid cooling cabinet. Each movable shielding component 103 is arranged in the corresponding first through hole 1023 and second through hole 1024 to shield the corresponding first through hole 1023 and second through hole 1024, so that when the joint of the water supply pipe 110 and the joint of the return pipe 120 leak, the splashing liquid is blocked by the corresponding movable shielding component 103. Each push-type driving member 104 is disposed on the liquid collecting structure. Part of each push-type driving member 104 extends out of the second surface 1022 . Each push-type driving member 104 is in transmission connection with the corresponding movable shielding assembly 103 .

[0036] In practical applications, such as Figure 1 and Figure 2 As shown, the number of movable shielding assemblies 103 can be set according to the number of connectors. When the connectors include only one water supply connector and one return connector, the number of movable shielding assemblies 103 can be two. Similarly, the number of pressing-type driving members 104 can be two. When the liquid leakage prevention device has two movable shielding assemblies 103 and two pressing-type driving members 104, parts of the pressing-type driving members 104 extend out of the second surface 1022 of the liquid leakage prevention device. At this time, when the water supply and return pipe connectors of the server need to be connected to the water supply and return pipe connectors of the liquid cooling cabinet, as the server approaches, the part of the pressing-type driving member 104 extending out of the second surface 1022 of the liquid leakage prevention device is pressed by the server, and the pressing-type driving member 104 drives the corresponding movable shielding assembly 103 to move, thereby leaking the corresponding first through hole 1023 or second through hole 1024. It should be understood that the movement mode here can be designed according to the shape of the liquid collecting mechanism, for example, it can be translation or rotation, etc., but is not limited thereto.

[0037] As can be seen from the above, in one or more technical solutions provided by the embodiments of the present disclosure, the leakage prevention device includes a liquid collecting pipe and a liquid collecting structure, wherein the liquid collecting pipe and the liquid collecting structure are connected. At the same time, the leakage prevention device also includes at least two movable shielding components, the liquid collecting structure has a first through hole opposite to the joint of the water supply pipe, and a second through hole opposite to the joint of the return pipe, and each movable shielding component is respectively arranged in the corresponding first through hole and second through hole to shield the first through hole and the second through hole. In this case, before the joints of the water supply pipe and the return pipe are connected to the data center equipment and the liquid cooling cabinet, the joint of the water supply pipe is shielded by the movable shielding plate located in the first through hole, and the joint of the return pipe is shielded by the movable shielding plate located in the second through hole. When the joints of the water supply pipe and the return pipe are damaged and splashing occurs, the liquid splashes onto the movable shielding plate, is collected by the liquid collecting structure, and then flows out through the liquid collecting pipe, thereby preventing the splashing liquid from damaging the equipment and liquid cooling cabinet of the data center.

[0038] The above-mentioned anti-leakage device also includes at least two push-type driving parts, which are connected to the movable shielding assembly in a transmission manner. When the joints of the water supply pipe and the return pipe on the data center equipment are connected to the joints of the water supply pipe and the return pipe of the liquid cooling cabinet, the push-type driving part is pressed by the data center equipment close to the liquid cooling cabinet, and the movable shielding assembly is controlled to move away, exposing the first through hole and the second through hole, so as to facilitate the connection of the joints of the water supply pipe and the return pipe on the data center equipment with the joints of the water supply pipe and the return pipe of the liquid cooling cabinet. At this time, the liquid collecting structure is gradually pushed by the equipment of the data center to the rear of the water supply pipe joint and the return pipe joint of the liquid cooling cabinet, so that The water supply pipe joints and return pipe joints of the liquid cooling cabinet and the water supply pipe joints and return pipe joints of the liquid cooling cabinet of the equipment in the data center are completely placed in the liquid collecting structure. When the joints are connected or when leakage occurs due to manual operation errors, since the joints on the data center equipment are female, the leaked liquid will splash toward the liquid cooling cabinet under the blocking effect of the female head, and will be collected by the liquid collecting structure and then flow out through the liquid collecting pipe, thereby avoiding damage to the equipment and liquid cooling cabinet of the data center by the splashing liquid, avoiding damage to the circuit by the liquid, and improving the safety of the equipment.

[0039] As a possible implementation, Figure 1 and Figure 2As shown, the above-mentioned leakage prevention device 100 also includes a fixed structure 105 connected to the water supply pipeline 110, the return water pipeline 120, and the first surface 1021 of the liquid collection structure 102, respectively. The joints of the water supply pipeline 110 and the return water pipeline 120 pass through the fixed structure 105. Because the fixed structure 105 is connected to the water supply pipeline 110, the return water pipeline 120, and the first surface 1021 of the liquid collection structure 102, respectively, the liquid collection structure 102 can be connected to the water supply pipeline 110 and the return water pipeline 120 through the fixed structure 105. That is, the leakage prevention device 100 of the exemplary embodiment of the present disclosure can be connected to the liquid cooling cabinet through the fixed structure 105. At this time, the fixed structure 105 has a through hole for accommodating the joints of the water supply pipeline 110 and the return water pipeline 120, so that the joints of the water supply pipeline 110 and the return water pipeline 120 can pass through the fixed structure 105 and communicate with corresponding joints on the equipment 130 in the data center.

[0040] In some alternative ways, such as Figure 1 and Figure 2 As shown, the fixed structure 105 may include a connector 1051 and at least two guide members 1052 provided on the connector 1051. In this case, the guide members 1052 may guide the movement direction of the liquid collection structure 102 and limit the movement trajectory of the liquid collection structure 102 to prevent the liquid collection structure 102 from falling out. For example, each guide member 1052 may include a first end and a second end, the first end of each guide member 1052 being an end of each guide member 1052 extending into the liquid collection structure 102, and the second end of each guide member 1052 being connected to the connector 1051. The first end of each guide member 1052 may have a plurality of limiting portions, and the plurality of limiting portions may move within the liquid collection structure 102 as the liquid collection structure 102 moves. When the server moves away from the liquid cooling cabinet, the liquid collection structure 102, guided by the guide 1052, moves along with the server away from the liquid cooling cabinet until the multiple stoppers on the first end of the guide 1052 contact the surface of the liquid collection structure, thereby limiting the further movement of the liquid collection structure 102 and preventing it from falling out. At this point, as the server continues to move away from the liquid cooling cabinet, the gap between the second surface 1022 of the liquid collection structure 102 and the server's mounting surface gradually increases.

[0041] For another example, the first end of each guide member 1052 may be shaped like a trumpet with a gradually increasing diameter. The trumpet-shaped first end is located within the liquid collection structure 102. When the server is connected to the liquid cooling cabinet, the trumpet-shaped first end is located within the liquid collection structure. When the server is disconnected from the liquid cooling cabinet and the server moves away from the liquid cooling cabinet, the liquid collection structure 102, guided by the guide member 1052, moves with the server away from the liquid cooling cabinet until the trumpet-shaped first end contacts the surface of the liquid collection structure, thereby limiting further movement of the liquid collection structure 102 and preventing it from falling out. At this point, as the server continues to move away from the liquid cooling cabinet, the gap between the second surface 1022 of the liquid collection structure 102 and the server's mounting surface gradually increases.

[0042] like Figure 1 and Figure 2 As shown, the connector 1051 and the guide 1052 included in the above-mentioned fixing structure are tightly fitted. For example, the connector 1051 and the guide 1052 can be connected together by a threaded connection. The connector 1051 is arranged between the water supply pipe 110 and the return pipe 120 and the guide 1052. The interface of the water supply pipe 110 and the interface of the return pipe 120 pass through the connector 1051 and the guide 1052. By installing a fluid connector in the guide 1052, the tightly fitted connector 1051 and the guide 1052 are pressed tightly between the manifold and the fluid connector. It should be understood that the fluid connector here has an external thread at one end close to the manifold, and an internal thread matching the external thread is left at the interface between the water supply pipe 110 and the return pipe 120 of the manifold, so that the fluid connector and the manifold can be fixed by a threaded connection. At this time, a connecting through-hole is opened on the side of the connector 1051 close to the water supply pipe 110 and the return pipe 120 of the manifold, and a guiding through-hole matching the connecting through-hole is provided in the guide 1052. The sizes of the connecting through-hole and the guiding through-hole match the interfaces of the water supply pipe 110 and the return pipe 120 of the manifold, so that the interfaces of the water supply pipe 110 and the return pipe 120 of the manifold can extend into the guide 1052 through the through-hole; the area of ​​the through-hole is smaller than the area of ​​the fluid connector close to the water supply pipe 110 of the manifold. and the area on the side of the return pipe 120, so that when the fluid connector is threadedly connected to the interface of the water supply pipe 110 of the manifold and the interface of the return pipe 120, the connecting piece 1051 and the guiding piece 1052 included in the fixed structure can be tightly pressed between the manifold and the fluid connector to realize the connection between the fixed structure and the water supply pipe 110 and the return pipe 120. The joint of the water supply pipe involved in the present disclosure refers to the fluid connector connected at the interface of the water supply pipe, and the joint of the return pipe refers to the fluid connector connected at the interface of the return pipe.

[0043] like Figure 1 and Figure 2 As shown, each guide member 1052 extends into the corresponding first through hole 1023 or second through hole 1024, and each movable shielding assembly 103 is located between the second surface 1022 and the guide member 1052. At this time, the fluid connector at the water supply line 110 and the fluid connector at the return line 120 can extend from the guide member 1052 into the liquid collection structure 102, and the movable shielding assembly 103 is located between the fluid connector at the water supply line 110 and the fluid connector at the return line 120 and the second surface 1022 of the liquid collection structure to block the splashing liquid generated when the fluid connector at the water supply line 110 and the fluid connector at the return line 120 leak. It should be understood that the shape of the guide member 1052 here can be set according to actual conditions, for example, it can be round, square, triangular, etc., but is not limited to this.

[0044] In some alternative ways, such as Figure 1 and Figure 2 As shown, the above-mentioned fixed structure 105 has at least two first end portions (not shown in the figure), each of which is respectively connected to the corresponding first through hole 1023 or the second through hole 1024, and the radial dimension of each first end portion is larger than the radial dimension of the corresponding first through hole 1023 or the second through hole 1024. It should be understood that the radial direction here can be the extension direction of the first surface 1021 of the liquid collection structure 102. For the fixed structure 105, only the radial dimension of each first end portion can be set to be larger than the radial dimension of the first through hole 1023 or the second through hole 1024, and the radial dimension of the remaining portion of the fixed structure 105 connected to the first end portion can be matched with the radial dimension of the first through hole 1023 and the second through hole 1024, so that when the liquid collection structure 102 moves on the fixed structure 105, the movement displacement can be restricted by the first end portion of the fixed structure 105, thereby preventing the liquid collection structure 102 from falling out.

[0045] For example, the above-mentioned fixed structure 105 may include a fixed structure body, a fixed structure first end and a fixed structure second end, wherein the fixed structure second end can be connected to the water supply pipe 110 or the return pipe 120, and the fixed structure body is respectively connected to the fixed structure first end and the fixed structure second end, the joint of the water supply pipe 110 and the joint of the return pipe 120 pass through the fixed structure first end and the fixed structure body, and the fixed structure first end (i.e., the first end) extends into the corresponding first through hole 1023 or the second through hole 1024 of the liquid collecting structure 102, the longitudinal dimension of the fixed structure first end is larger than the aperture of the first through hole 1023 or the second through hole 1024, and the radial dimension of the fixed structure body is smaller than the aperture of the first through hole 1023 or the second through hole 1024. Therefore, when the liquid collecting structure 102 moves in a direction away from the fixed structure 105, the movement direction of the liquid collecting structure 102 can be guided by the fixed structure body, and the movement position of the liquid collecting structure 102 can be limited by the fixed structure first end (i.e., the first end) to prevent the liquid collecting structure 102 from falling out. It should be understood that the shapes of the fixing structure body, the fixing structure first end and the fixing structure second end of the fixing structure 105 can be set according to actual conditions and are not limited here.

[0046] For example, Figure 1 and Figure 2 As shown, the guide member 1052 may include a first end face and a second end face, wherein the first end face is disposed proximate to the liquid collecting structure 102, and the second end face is disposed proximate to the manifold, and the first end face of each guide member 1052 is respectively located within the first through hole 1023 or the second through hole 1024 of the corresponding liquid collecting structure 102. In this case, the connector 1051 and the guide member 1052 included in the fixing structure 105 may be fixed together by a threaded connection. The connector 1051 and the guide member 1052 have the through holes described above, through which the interfaces of the water supply pipeline 110 and the return pipeline 120 of the manifold can extend into the guide member 1052. The connector 1051 and the guide member 1052 are fixed to the manifold by threading the fluid connector to the interfaces of the water supply pipeline 110 and the return pipeline 120 of the manifold. The first end portion may be the first end surface of each corresponding guide member 1052, and at least one protrusion may be provided on the first end surface to limit the movement position of the liquid collection structure 102 and prevent the liquid collection structure 102 from falling out. It should be understood that the outer diameter of the protrusion is larger than the aperture of the first through hole 1023 or the second through hole 1024 on the first surface 1021 of the liquid collection structure 102, and the outer diameter of the area other than the protrusion on the second end surface of the guide member 1052 is smaller than the aperture of the first through hole 1023 or the second through hole 1024 of the liquid collection structure 102, so as to facilitate the sliding of the liquid collection structure 102 on the guide member 1052.

[0047] In practical applications, such as Figure 1 and Figure 2 As shown, when the server is connected to the liquid cooling cabinet, as the server gradually approaches the liquid cooling cabinet, the liquid collecting structure 102 is pushed by the server toward the liquid cooling cabinet until the fluid connector at the water supply line and the fluid connector at the return line of the server are connected to the fluid connector at the water supply line and the fluid connector at the return line of the liquid cooling cabinet. At this time, the distance between the liquid collecting structure 102 and the liquid cooling cabinet is the smallest, and the fluid connector at the water supply line and the fluid connector at the return line of the server and the fluid connector at the water supply line and the fluid connector at the return line of the liquid cooling cabinet are all located inside the liquid collecting structure 102. When liquid leakage occurs, due to the obstruction of the liquid collecting structure 102, the splashed liquid is collected by the liquid collecting structure 102 and will not splash on the ground, the liquid cooling cabinet, and the server, so as to protect the safety of the server and the liquid cooling cabinet. When the server stops working, the fluid connector at the water supply pipe and the fluid connector at the return pipe of the server can be disconnected from the fluid connector at the water supply pipe and the fluid connector at the return pipe of the liquid cooling cabinet. At this time, as the server moves away from the liquid cooling cabinet, the liquid collecting structure 102 gradually moves away from the liquid cooling cabinet until the first surface 1021 of the liquid collecting structure 102 slides to the first end of the fixed structure 105, and the liquid collecting structure 102 stops moving.

[0048] In some alternative ways, such as Figure 1 and Figure 2 As shown, the fixing structure 105 further includes a plurality of elastic members (not shown), which are mounted on the guide member 1052 and are respectively connected to the first surface 1021 of the liquid collecting structure 102 and the connecting member 1051. The elastic members mounted on the guide member 1052 ensure that when the equipment 130 in the data center is disconnected from the liquid cooling cabinet, the liquid collecting structure 102 can be restored to its original position away from the liquid cooling cabinet. At this time, the part of the push-type driving member 104 that extends out of the second surface 1022 gradually recovers as the equipment 130 of the data center moves, so that the movable shielding component 103 that is transmission-connected to the push-type driving member 104 can move to a position that blocks the corresponding first through hole 1023 and the second through hole 1024, to ensure that before the water supply pipe joint 110 and the return pipe joint 120 of the equipment 130 of the data center are connected to the water supply pipe joint 110 and the return pipe joint 120 of the liquid cooling cabinet, when the water supply pipe joint 110 and the return pipe joint 120 of the liquid cooling cabinet leak, the splashed liquid can be collected by the movable shielding component 103 and the liquid collecting structure 102, and discharged to the water collecting tray through the liquid collecting pipe 101, thereby improving the safety of the equipment 130 of the data center before the water supply pipe joint and the return pipe joint of the equipment 130 of the data center are connected to the water supply pipe joint and the return pipe joint of the liquid cooling cabinet.

[0049] Since the liquid cooling cabinet and the equipment in the data center in the exemplary embodiment of the present disclosure are connected by a blind plug connection, the joints of the water supply pipe and the return pipe of the liquid cooling cabinet and the joints of the water supply pipe and the return pipe of the equipment in the data center may be damaged due to improper manual operation and other reasons during the blind plug connection, thereby causing leakage problems.

[0050] In some alternative ways, such as Figure 1 and Figure 2 As shown, in order to overcome the above problems, the fixed structure 105 provided by the exemplary embodiment of the present disclosure may further include a connector 1051 and an elastic positioning member 1053 provided on the connector 1051. The connector 1051 is provided on the water supply pipe 110 and the return pipe 120, and the joint of the water supply pipe 110 and the joint of the return pipe 120 pass through the connector 1051. The elastic positioning member 1053 passes through the liquid collecting structure 102, and part of the structure of the elastic positioning member 1053 extends out of the second surface 1022. By providing the elastic positioning member 1053 with a part of its structure extending out of the second surface 1022 of the liquid collecting structure 102, the equipment 130 in the data center can determine the installation position of the equipment 130 in the data center by determining the position of the elastic positioning member 1053, thereby avoiding the occurrence of leakage accidents caused by improper manual operation. It should be understood that the number and position of the elastic positioning members 1053 can be determined according to the position and number of holes on the equipment 130 of the data center that match the elastic positioning members 1053, and are not limited here.

[0051] For example, when the aforementioned fixing structure includes an elastic positioning member and a connecting member, the connecting member can be threadedly connected to the water supply pipe and the water return pipe, so that the joints of the water supply pipe and the water return pipe pass through the connecting member. The elastic positioning member can then be threadedly connected to the connecting member, and a positioning through-hole penetrating the liquid collecting structure is simultaneously formed at a corresponding position of the liquid collecting structure. The elastic positioning member is then passed through the positioning through-hole of the liquid collecting structure, thereby completing the connection between the liquid collecting structure and the elastic positioning member.

[0052] The elastic positioning member may include a positioning pin and an elastic member mounted on the positioning pin. It should be understood that the elastic member involved in the exemplary embodiments of the present disclosure may be a spring or other elastic member, and is not limited here. During assembly, one end of the elastic member is connected to the connector and the other end is connected to the first surface of the liquid collection structure, so that the liquid collection structure can return to its initial state (away from the liquid cooling cabinet) when the equipment in the data center is disconnected from the liquid cooling cabinet.

[0053] In order to limit the movement of the liquid collecting mechanism, a limiting portion can be provided on the elastic positioning member. The limiting portion is located within the liquid collecting mechanism. The location of the limiting portion can be set according to actual needs and is not limited here. For a structural description of the limiting portion, please refer to the previous description of the guide member limiting the position of the liquid collecting mechanism, and will not be repeated here.

[0054] In order to ensure that the liquid collection mechanism can move according to the preset motion trajectory, the above-mentioned fixed structure may also include a plurality of elastic limiting members, which are respectively connected to the connecting member and the liquid collection structure. The elastic limiting member may include an elastic limiting column and an elastic member sleeved on the elastic limiting column. One end of the elastic limiting column is connected to the connecting member, and the other end of the elastic limiting column extends into the first surface of the liquid collection structure. One end of the elastic member is connected to the connecting member, and the other end of the elastic member is connected to the first surface of the liquid collection structure. And the end of the elastic limiting column extending into the first surface of the liquid collection structure has a limiting portion. For the structural description of the limiting portion, please refer to the previous description on the guiding member limiting the liquid collection structure, which will not be repeated here. It should be understood that the number and position of the elastic limiting members can be set according to actual needs and are not limited here.

[0055] In actual applications, elastic limiters can be fixedly connected at the four corners of the liquid collection structure in sequence, so that the liquid collection structure can move according to the prescribed motion trajectory under the restriction of the elastic limiters. At the same time, when the equipment in the data center is disconnected from the liquid cooling cabinet, under the action of the elastic limiters and elastic positioning members, the liquid collection structure can move away from the liquid cooling cabinet and stop at the initial position to ensure that the liquid collection structure can be automatically restored and the movable shielding assembly and the liquid collection structure can be used to protect the safety of the equipment in the data center.

[0056] In some alternatives, Figure 3 The schematic diagram shows the structure of the installation part of a liquid leakage prevention device 100 and a water supply pipe 110 and a return pipe 120 of a liquid cooling cabinet according to an exemplary embodiment of the present disclosure. Figure 3 ,like Figures 1 to 3 As shown, the liquid collection structure 102 may include a box body 1025 and a guide groove 1026 provided on the box body 1025. The guide groove 1026 is connected to the liquid collection pipe 101, and the box body 1025 is provided on the fixed structure 105. The leaked liquid collected in the box body 1025 is discharged into the liquid collection pipe 101 through the guide groove 1026 connected to the box body 1025, and then discharged to the water collection tray through the liquid collection pipe 101 for collection, thereby protecting the safety of the equipment 130 in the data center and the ground wiring, and preventing the occurrence of leakage accidents. It should be understood that the shape of the box body 1025 here can be set according to actual conditions, for example, it can be rectangular, irregular, etc., and this is not limited here.

[0057] In some alternative ways, such as Figures 1 to 3 As shown, in order to prevent leakage from the guide groove 1026 or the guide groove 1026 is of an inappropriate size, so that the leaked liquid cannot directly flow into the collecting pipe 101, the above-mentioned anti-leakage device 100 can also include a collecting groove 106 connected to the collecting pipe 101. The collecting groove 106 is located at the lower part of the guide groove 1026 to collect the liquid leaked or flowing out of the guide groove 1026, and send the collected liquid into the collecting pipe 101, and then guide it out to the water collection tray for collection in the collecting pipe 101 to protect the safety of the equipment 130 in the data center and the ground lines, and avoid leakage accidents.

[0058] As a possible implementation, Figures 1 to 3 As shown, the above-mentioned push-type driving member 104 may include a push switch and a driving member (not shown in the figure) connected to the corresponding movable shielding assembly 103. The driving member is provided on the liquid collecting structure 102, and the push switch extends out of the second surface 1022 of the liquid collecting structure 102. When the push switch is pressed, the driving member drives the movable shielding assembly 103 to move, exposing the corresponding first through hole 1023 and second through hole 1024. It should be understood that the driving member here can be a gear driving member, a sliding driving mechanism, etc. Since the mechanical transmission method of converting linear motion into rotational motion is all existing technology, the type of driving member is again not limited. As long as the driving method of the movable shielding assembly 103 can be realized in the present disclosure, it is within the optional range.

[0059] For example, the driving member may be a sliding driving member, in which case the driving member may include a slide, a slider located on the slide, a cam, and a spring pin. The slide is provided with a plurality of slide limiters, and the slider is provided with a plurality of slider limiters. The slide limiters and the slider limiters are used to cooperate in limiting the movement position of the movable shielding assembly. The cam is located on the slider, and the movable shielding assembly is sleeved on the cam. The spring pin is connected to the cam, and the push switch is connected to the slider. When the push switch is pressed by the equipment in the data center, the slider begins to move with the movement of the push switch. After the movable shielding assembly gradually leaves the restriction of the limit block, the movable shielding assembly begins to move. When the movable shielding assembly moves to a position where it leaks out of the corresponding first through hole and second through hole, the slide limit block and the slider limit block limit the movement of the movable shielding assembly, causing the movable shielding assembly to stop moving. When the equipment in the data center is disconnected from the liquid-cooled cabinet, as the push switch is released, the slider moves away from the liquid-cooled cabinet under the elastic force of the spring pin until the movable shielding assembly is restricted by another set of slide limit blocks and slider limit blocks and stays in a position that blocks the corresponding first through hole and second through hole.

[0060] The exemplary embodiments of the present disclosure further provide a liquid-cooled cabinet, comprising at least one exemplary liquid leakage prevention device and a manifold, wherein the liquid leakage prevention device is mounted on the manifold. The beneficial effects of the liquid-cooled cabinet provided by the exemplary embodiments of the present disclosure can be found in the aforementioned description of the beneficial effects of the liquid leakage prevention device and are not further elaborated here.

[0061] In actual applications, since the manifold usually has multiple water supply pipe joints and multiple return pipe joints, the anti-leakage device can have multiple ones, and the multiple anti-leakage devices are arranged according to the positions of the multiple water supply pipe joints and multiple return pipe joints of the manifold, which is not limited here. The liquid cooling cabinet is provided with a cooling liquid supply pipe and a cooling liquid return pipe for transporting the cooling liquid flowing out of the heat exchange unit. There are multiple joints on the cooling liquid supply pipe and the cooling liquid return pipe to distribute the cooling liquid to each layer of the heat dissipation unit. The cooling liquid supply pipe and the cooling liquid return pipe are connected to different numbers of joints according to needs. The cooling liquid supply pipe and the cooling liquid return pipe at the liquid cooling cabinet end are connected to the cooling liquid supply pipe and the cooling liquid return pipe at the equipment end of the data center through the first through hole and the second through hole extending along the first surface and the second surface on the liquid collection structure, respectively. The water supply and return pipes of the liquid-cooled cabinet are respectively connected to the Cooling Distribution Unit (CDU). After the connection, the low-temperature coolant from the heat exchange unit begins to circulate. The coolant in the water supply pipe enters the equipment end of the data center through the joints of each water supply pipe to absorb heat, and then returns to the coolant return pipe at the liquid-cooled cabinet end through the joint of the equipment coolant return pipe of the data center, and finally is transmitted to the heat exchange unit for heat exchange.

[0062] Figure 4 FIG. 1 shows a partial structural diagram of a liquid leakage prevention device provided according to an exemplary embodiment of the present disclosure and installed with equipment in a data center, as shown in FIG. Figure 4As shown, the data center equipment 130 is sloped and includes a collection portion 1301 located at the lowest point of the equipment 130, allowing leaked liquid to collect there. Collection portion 1301 is provided with a through-hole located above the liquid collection trough 106 of the liquid leakage prevention device 100. In the event of a leak, the leaked coolant, due to the slope, flows into collection portion 1301 and then into the through-hole of collection portion 1301, allowing the collected liquid to be directed through the liquid collection trough 106 to the collection pipe 101, thereby protecting the data center equipment 130. Quick connectors can be used to connect the coolant supply and return pipes 110 and 120 of the liquid-cooled cabinet to those of the data center equipment 130. The quick connector consists of two parts: the liquid cooling cabinet part and the data center equipment 130 part. Before the quick connector is pressed and docked, both parts are in a closed state, preventing liquid from flowing. When connecting the quick connector of the liquid cooling cabinet part and the quick connector of the data center equipment 130 part, the two parts need to be pressed together and fixed. As the quick connector of the liquid cooling cabinet part and the data center equipment 130 part are pressed and docked, the piston inside the quick connector is pressed and gradually forms a connecting channel. When the two parts of the quick connector are fully pressed and docked, the pipeline is completely connected, and coolant can flow normally through the connector.

[0063] Figure 5 FIG. 1 shows a partial structural diagram of an exhaust device of a liquid cooling cabinet provided according to an exemplary embodiment of the present disclosure. Figure 5 As shown, an exhaust device 140 is typically installed on the top of the liquid-cooling cabinet to remove air that enters when the water supply and return pipe connections 110 and 120 of the liquid-cooling cabinet are connected to the water supply and return pipe connections 110 and 120 of the data center equipment 130, or to remove gas that enters during operation. However, during the exhaust process, coolant may be accidentally discharged. If this accidentally discharged coolant splashes onto the data center equipment 130 or the liquid-cooling cabinet, it may damage the data center equipment 130 and the liquid-cooling cabinet.

[0064] As a possible implementation, Figure 5As shown, to overcome the above-mentioned problems, the liquid cooling cabinet of the exemplary embodiment of the present disclosure may further include a drainage pipe 150. The drainage pipe 150 is provided on the exhaust device 140, with one end of the drainage pipe 150 connected to the exhaust device 140 of the liquid cooling cabinet and the other end connected to the liquid leakage prevention device 100. Specifically, the other end of the drainage pipe 150 may be connected to the liquid collection pipe 101 of the liquid leakage prevention device 100, so that coolant leaking from the exhaust device 140 can be drained by the drainage pipe 150 into the liquid collection pipe 101, and then directed by the liquid collection pipe 101 into the water collection pan, thereby protecting the equipment and liquid cooling cabinet of the service center and preventing the occurrence of unsafe accidents.

[0065] Although the present disclosure has been described with reference to specific features and embodiments thereof, it will be apparent that various modifications and combinations may be made thereto without departing from the spirit and scope of the present disclosure. Accordingly, this specification and the drawings are merely illustrative of the present disclosure as defined by the appended claims and are deemed to cover any and all modifications, variations, combinations or equivalents within the scope of the present disclosure. Obviously, those skilled in the art may make various modifications and variations to the present disclosure without departing from the spirit and scope of the present disclosure. Thus, the present disclosure is intended to include such modifications and variations if they fall within the scope of the claims of the present disclosure and their equivalents.
