Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling cabinets, and in particular to an anti-leakage device and a liquid cooling cabinet. Background Art

[0002] Cold plate liquid cooling uses a cold plate device to cool the main heat-generating components in the server. The cold plate device covers the main heat-generating components of the server. The low-temperature coolant flows out of the coolant distribution unit (CDU) and enters the liquid supply main pipe of the manifold. Then, it passes through the liquid supply branch pipe and the fluid connection joint, enters the cold plate device to exchange heat with the heat-generating components and turns into high-temperature coolant. Then, it passes through the coolant return pipe and the fluid connection joint into the Manifold return liquid main pipe, and finally enters the CDU for heat exchange and turns into low-temperature coolant, completing the cycle.

[0003] Liquid cooling systems with cold plates are prone to leaks at the quick-connect fittings. Prior to connecting the cooling water supply and return pipes to the cabinet, the quick-connect fittings were not protected by leak-proof devices. Damage to the quick-connect fittings could cause splashing, potentially damaging the system. Liquid leakage could also occur during the insertion and removal of the quick-connect fittings. Furthermore, prior art approaches to connecting the cooling water supply and return pipes to the cabinet and servers fail to address the issue of cooling water leaks at these interfaces. Summary of the Invention

[0004] The embodiments of the present application provide a leakage prevention device and a liquid cooling cabinet to solve the technical problem that liquid leakage is more likely to occur in the quick connector part of the pipeline, which may cause damage to the system.

[0040] The present invention provides an anti-leakage device and a liquid cooling cabinet.

[0041] In the embodiment of the present invention, Figures 1 to 3 As shown, the anti-leakage device 10 includes a manifold connector 310, a server connector 410, an outer shell 100 and a paddle 200. The manifold connector 310 and the server connector 410 are plugged together. The outer shell 100 is externally mounted on the manifold connector 310. The outer shell 100 protrudes from the manifold connector 310 toward the server connector 410 to form an anti-leakage connection portion 110. The anti-leakage connection portion 110 is provided with a plug-in interface 120. The manifold connector 310 and the server connector 410 are plugged together through the plug-in interface 120. The paddle 200 is used to movably open or close the plug-in interface 120.

[0042] Cold plate liquid cooling uses a cold plate device to cool the main heating elements in the server 400. The cold plate device covers the main heating elements of the server 400. The low-temperature coolant flows out of the CDU (Cooling Distribute Unit) and enters the coolant supply pipe 20 of the manifold 300. Then, it passes through the liquid supply branch pipe and the manifold joint 310 and enters the cold plate device to exchange heat with the heating elements and turn into high-temperature coolant. Then, it passes through the return pipe and the server joint 410 to enter the coolant return pipe 30, and finally enters the CDU for heat exchange and turns into low-temperature coolant, completing the cycle.

[0043] The manifold connector 310 is used to separately supply or recover the coolant supply pipe 20 and the coolant return pipe 30. The manifold connector 310 can be a male end or a female end, which is not particularly limited here.

[0044] The server connector 410 is used to plug into the manifold connector 310, thereby establishing a connection between the manifold 300 and the server 400 system. Similarly, the server connector 410 and the manifold connector 310 are mated and plugged together. The server connector 410 can be male or female depending on the matching of the manifold connector 310, without any special limitation here.

[0045] The outer shell 100, serving as the main structure of the entire device, provides a leak-proof connection portion 110. This cavity houses key components such as the manifold connector 310 and ensures that the manifold connector 310 and the server connector 410 are in a closed environment during the connection process. This significantly reduces the risk of liquid leakage due to connection problems. The leak-proof connection portion can be circular, square, or a special shape, depending on the shape of the manifold connector 310, and is not specifically limited here.

[0046] The paddle 200 is used to open and close the plug port 120, thereby achieving a liquid-tight seal during the connection process. Before the manifold connector 310 is connected to the server connector 410, the paddle 200 ensures the leak-proof connection portion 110 is sealed. When the manifold connector 310 and the server connector 410 are connected, the paddle 200 can provide connection conditions.

[0047] The anti-leakage device 10 provided in the embodiment of the present application is configured such that the outer shell 100 is placed outside the manifold connector 310, so that before the Manifold is connected to the server 400, the entire manifold connector 310 is surrounded by the outer shell 100. The outer shell 100 is provided with a plug interface 120 to support the smooth connection between the manifold connector 310 and the server connector 410. At the same time, the plug interface 120 is covered with a paddle 200 to prevent spraying caused by damage to the manifold connector. The paddle 200 is used to flexibly open or close the plug interface 120. When the paddle 200 is pushed by the server connector 410, it can be flipped to open the plug interface 120 so that the male and female connectors of the connector 600 can be smoothly plugged in and out. If leakage or liquid splashing occurs due to damage to the manifold connector 310, the outer shell 100 and the paddle 200 will block the liquid splashing and collect the liquid, thereby avoiding liquid splashing and improving the protection of the server 400 system.

[0048] Reference Figure 1 and Figure 3In one embodiment, a liquid-repellent groove 140 is provided on one side of the outer shell 100 near the head of the manifold 300, and the liquid-repellent groove 140 is recessed toward the side away from the anti-leakage connection 110. It can be understood that the design of the liquid-repellent groove 140 can effectively guide the liquid that may be generated to flow in a direction away from the anti-leakage connection 110. When liquid leakage occurs at the head or joint of the manifold 300, the liquid can be quickly guided and collected by the liquid-repellent groove 140, thereby preventing the liquid from further flowing to and accumulating in the critical plug-in area, that is, the anti-leakage connection 110. By guiding the flow of liquid, it is less likely for the liquid to accumulate or spread inside the device, thereby improving the overall anti-leakage performance. Since the liquid-repellent groove 140 can concentrate the leaked liquid in one area, this makes cleaning and maintenance work simpler and more efficient. Users can more easily identify and remove accumulated liquid to keep the device clean and operating normally.

[0049] In some embodiments, the lyophobic groove 140 may be configured as a groove body having a bottom wall or side wall with a certain slope.

[0050] Reference Figures 1 to 3 In one embodiment, the leakage prevention device 10 further includes a drain riser 150, which is connected to the bottom of the sump 140. As will be appreciated, the drain riser 150 is connected to the bottom of the sump 140. When liquid accumulates in the sump 140, it can be quickly drained through the drain riser 150. This prevents liquid from remaining in the sump 140 for extended periods, reducing the risk of potential damage to other components within the device. The drain riser 150 creates a continuous drainage path, allowing liquid to flow smoothly from the leak source through the sump 140 to the drain riser 150 and ultimately out of the device. This significantly enhances the device's leak prevention effectiveness, ensuring that even if a leak occurs, the liquid is quickly drained, preventing it from spreading and causing further damage. The design of the drain riser 150 simplifies the removal of accumulated liquid. Maintenance personnel can clean and drain the liquid directly through the drain riser 150 without disassembling other parts of the device, thereby reducing maintenance effort and costs. The synergistic effect of the drainage riser 150 and the liquid drainage groove 140 makes the leakage prevention device 10 more reliable and efficient in dealing with liquid leaks. This design not only improves the leakage prevention performance of the device, but also enhances its ability to respond to emergencies, ensuring the stable operation of the server 400 system.

[0051] Reference Figure 2In one embodiment, the leakage prevention device 10 further includes a connector 600. The paddle 200 is disposed within the leakage prevention connection portion 110 and is rotatably connected to the peripheral side of the plug port 120 via the connector 600. It is understood that the paddle 200 is connected to the outer shell 100 via the connector 600 and is connected within the leakage prevention connection portion 110 of the outer shell 100. This allows the paddle 200 to flip when pushed by the server 400 connector, thereby opening the plug port 120 and allowing the manifold connector 310 and the server 400 connector to be smoothly plugged in and out of the leakage prevention connection portion 110. This makes plugging and unplugging operations more convenient and also improves the device's usability.

[0052] Reference Figure 3 In one embodiment, the anti-leakage device 10 further includes an elastic member 500, which extends along the axis of the plug port 120 and is disposed within the anti-leakage connection portion 110. The elastic member 500 is connected between the outer shell 100 and the manifold connector 310. It is understood that during the connection between the Manifold and the server 400, coolant leakage may occur when the manifold connector 310 is plugged in and out of the server 400 connector. Furthermore, if the installer makes a mistake during the quick connector docking process, liquid may splash at the connection between the two connectors. The outer shell 100 is configured to move forward and backward via a spring member. During the connection process, as the server connector 410 advances, the outer shell 100 gradually moves backward until the server connector 410 is fully connected to the manifold connector 310. At this point, the outer shell 100, due to the action of the spring member, presses against the interface between the server 400 and the manifold 300.

[0053] Specifically, when the server 400 is connected to the manifold 300, the server 400 connector protruding from the server 400 will first push the paddle 200 away and enter the leak-proof connection part 110 inside the outer shell 100. Then, as the server 400 moves, the outer shell 100 retreats, and the server 400 connector contacts the manifold connector 310. During this contact process, it remains in the leak-proof connection part 110 until the server 400 is fully connected to the Manifold. During the connection process between the server 400 and the Manifold, the connection interface remains in the leak-proof connection part 110. If leakage or splashing occurs, the coolant will be blocked and collected by the outer shell 100.

[0054] Reference Figures 1 to 3In one embodiment, the leakage prevention device 10 further includes a guide pin 700, one end of which is connected to the manifold connector 310, and a guide hole 130 is provided at a position corresponding to the guide pin 700 on the outer shell 100, and the other end of the guide pin 700 is movably inserted into the guide hole 130. It can be understood that by connecting one end of the guide pin 700 to the manifold connector 310 and the other end being movably inserted into the guide hole 130 on the outer shell 100, it can be ensured that the manifold connector 310 maintains the correct path and direction when moving along the axial direction of the plug interface 120, preventing the connector from being offset or tilted during insertion or removal, thereby ensuring the accuracy and stability of the connection. The cooperation between the guide pin 700 and the guide hole 130 can achieve precise positioning of the manifold connector 310 in the outer shell 100. It can ensure that the connector can accurately dock with the server connector 410 after being inserted into place, thereby improving the reliability and sealing of the connection. The presence of the guide pin 700 can also prevent the user from making misoperations during the connection process, such as inserting in the wrong direction or inserting to an insufficient depth, to a certain extent, thereby improving the safety and ease of connection.

[0055] Reference Figure 2 and Figure 3 In one embodiment, the manifold connector 310 includes a return connector 320 and a supply connector 330, with the guide pin 700 positioned between the return connector 320 and the supply connector 330. It will be appreciated that the return connector 320 is a portion of the manifold connector 310 and is used to connect to the coolant return pipe 30, which directs water back from the system. In a coolant system, the return connector 320 returns used coolant to the refrigeration unit for further cooling.

[0056] The water supply connector 330 is another part of the manifold connector 310, which is used to connect the cooling liquid water supply pipe 20, and is about to send the cooled water into the system. In the cold liquid system, the role of the water supply connector 330 is to transport the cooled cold liquid to the area that needs refrigeration.

[0057] The guide pin 700, located between the return and supply connectors 320 and 330, further enhances guidance and positioning when connecting the return and supply connectors 320 and 330 to the server connector 410. This ensures accuracy and stability during movement and docking of the manifold connector 310. The guide pin 700, coupled with the guide hole 130 in the outer shell 100, ensures that the manifold connector 310 moves along the correct path and direction, preventing deviation or tilting during connection.

[0058] In one embodiment, the leakage prevention device 10 further includes a water collection tray, which is positioned opposite the collection trough provided on the outer shell 100 and is located at the bottom of the outer shell 100. As will be appreciated, if a leak occurs in the connection device, the leaked liquid is collected by the outer shell 100. The coolant from each outer shell 100 is collected in the collection trough and then combined and collected in the collection tray below the cabinet. This prevents the liquid from spreading outside the device or contaminating the environment. Workers can easily remove the collection tray for cleaning without disassembling or moving the entire device.

[0059] Figure 1 and Figure 3 In one embodiment, a drain trough 420 is provided below the server connector 410 corresponding to the server connector 410 of the server 400. The drain trough 420 communicates with the interior of the server 400. After the server connector 410 and the manifold connector 310 are plugged in and fixed, the drain trough 420 is located within the anti-leakage connection portion 110. It will be appreciated that the drain trough 420 communicates with the interior of the server 400. When liquid leaks from the server 400, the liquid can be quickly drained through the drain trough 420, preventing liquid accumulation within the server 400 and thus protecting the normal operation of the server 400. When the server connector 410 and the manifold connector 310 are plugged in and fixed, the drain trough 420 is located within the anti-leakage connection portion 110. Leaked liquid can be quickly collected by the drain trough 420 and drained into the anti-leakage connection portion 110, thereby reducing the risk of liquid leaking into the external environment.

[0060] In one embodiment, the inner wall of the server 400 is provided with an inclined guide surface, and the drain groove 420 is connected to the end of the bottom of the guide surface. It is understandable that when liquid leaks inside the server 400, the inclined guide surface can quickly drain the liquid to the lowest point, that is, the bottom end of the guide surface can ensure that the liquid will not be retained inside the server 400, but will be quickly guided to a predetermined drainage path. By connecting the drain groove 420 to the end of the bottom of the guide surface, the leaked liquid can be collected in the drain groove 420. The drain groove 420 serves as a collection point for liquids and can accommodate and temporarily store these liquids to prevent them from further spreading or causing more serious damage. The drain groove 420 is connected to the anti-leakage connection 110. Once the liquid is collected in the drain groove 420, it can be quickly discharged from the server 400 through the drain groove 420, thereby preventing the liquid from accumulating inside the server 400 and possibly causing damage to the equipment.

[0061] Reference Figure 1In one embodiment, the anti-leakage device 10 includes at least two outer shells 100, and the two outer shells 100 are detachably connected to each other. The number of outer shells 100 wrapped around the manifold 300 can be divided into several separately disassembled parts according to the number of servers 400, thereby realizing a modular design. This improves production efficiency, reduces costs, and facilitates transportation and storage. Users can increase or decrease the number of outer shells 100 as needed to adapt to different application scenarios. When the manifold 300 needs maintenance and inspection, it can be checked and repaired as needed, and the outer shell of that part can be removed for repair separately. It can be replaced separately without replacing the entire connecting device, thereby reducing maintenance costs. The outer shells 100 can be manufactured, transported and stored independently, and the modular design makes the connecting device easy to expand and maintain.

[0062] The present invention also provides a liquid cooling cabinet, which includes the above-mentioned anti-leakage device 10. The specific structure of the anti-leakage device 10 refers to the above-mentioned embodiment. Since the liquid cooling cabinet adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
