Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling cabinets, and in particular to a leakage-proof and spray-proof connection 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-proof and spray-proof connection device and a liquid-cooling cabinet, which are used 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.

[0013] In one embodiment, the manifold joint includes a return water joint and a water supply joint, and the guide pin is provided between the return water joint and the water supply joint.

[0014] In one embodiment, the anti-leakage and anti-spray connection device further includes a water collecting tray, which is arranged opposite to the sub-collecting tank provided on the outer shell, and is located at the bottom of the outer shell.

[0015] In one embodiment, the server is provided with a drainage groove below the server connector, the drainage groove is connected to the interior of the server, and after the server connector and the manifold connector are plugged and fixed, the drainage groove is located in the leak-proof connection cavity.

[0019] The leakage-proof and spray-proof connection device provided in the embodiment of the present application is provided with an outer shell and a leak-proof connection cavity in the outer shell, so that before the Manifold is connected to the server, the entire manifold connector is surrounded by the outer shell, and the outer shell is provided with a plug interface to support the smooth connection of the manifold connector and the server connector. At the same time, the plug interface is covered with a baffle to prevent spraying caused by damage to the manifold connector. The baffle is used to movably open or close the plug interface.

[0040] The present invention provides a liquid leakage and spray-proof connection device and a liquid cooling cabinet.

[0041] In the embodiment of the present invention, Figures 1 to 3 As shown, the leakage-proof and injection-proof connection device 10 includes at least one outer shell 100, a blocking cover 200, a manifold connector 310 and a server connector 410. The outer shell 100 has a leakage-proof connection cavity 110 and a plug interface 120 connected to the leakage-proof connection cavity 110; the blocking cover 200 is used to movably open or close the plug interface 120; the manifold connector 310 is arranged in the leakage-proof connection cavity 110, and the manifold connector 310 can move relative to the outer shell 100 along the axial direction of the plug interface 120; the server connector 410 is plugged into the manifold connector 310 through the plug interface 120.

[0042] The outer shell 100, serving as the main structure of the entire device, provides a leak-proof connection cavity 110, which 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.

[0043] The cover 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 cover ensures the leak-proof connection cavity 110 is sealed. When the manifold connector 310 and the server connector 410 are connected, the cover 200 can ensure the connection conditions.

[0044] The mobility of the manifold connector 310 ensures flexibility during insertion, making connection more convenient and quick, and helping to reduce the risk of leakage caused by improper connector positioning. The manifold connector 310 can be male or female, without specific limitation.

[0045] 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.

[0046] The leakage-proof and spray-proof connection device 10 provided in the embodiment of the present application is configured with an outer shell 100 and a leakage-proof connection cavity 110 in the outer shell 100, so that before the Manifold is connected to the server 400, the manifold connector 310 of the entire Manifold is surrounded by the outer shell 100, and 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 blocking cover 200 for preventing spraying caused by damage to the manifold connector. The blocking cover 200 is used to movably open or close the plug interface 120. The blocking cover 200 can be flipped when it is pushed by the server 400 connector to open the plug interface 120, so that the male and female heads of the connector 600 can be smoothly plugged in and out. If leakage or splashing of liquid occurs due to damage to the manifold joint 310 , the outer shell 100 and the blocking cover 200 will block the splashing of liquid and collect the liquid, thereby avoiding liquid splashing and improving protection for the server 400 system.

[0047] Reference Figure 3 In one embodiment, the leak-proof and spray-proof connection device 10 further includes an elastic member 500. The elastic member 500 extends along the axis of the plug port 120 and is disposed within the leak-proof connection cavity 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 an error 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 and the manifold connector 310 are fully connected. 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.

[0048] Specifically, when the server 400 is connected to the manifold 300, the server 400 connector extending from the server 400 will first push open the cover 200 and enter the leak-proof connection cavity 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, the connector remains in the leak-proof connection cavity 110 until the server 400 and the Manifold are fully connected. During the connection process, the connection interface remains in the leak-proof connection cavity 110. If leakage or splashing occurs, the coolant will be blocked and collected by the outer shell 100.

[0049] Reference Figure 2 In one embodiment, the anti-leakage and anti-spray connection device 10 further includes a connector 600, a blocking cover 200 disposed within the anti-leakage connection cavity 110, and the blocking cover 200 is rotatably connected to the peripheral side of the plug port 120 via the connector 600. It is understood that the blocking cover 200 is connected to the outer shell 100 via the connector 600, and the blocking cover 200 is connected to the anti-leakage connection cavity 110 of the outer shell 100. This allows the blocking cover 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 anti-leakage connection cavity 110. This makes plugging and unplugging operations more convenient and also improves the flexibility of the device.

[0050] Reference Figures 1 to 3 In one embodiment, the anti-leakage and anti-spray connection 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 formed in the outer shell 100 at a position corresponding to the guide pin 700, 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 movably inserted into the guide hole 130 on the outer shell 100, the manifold connector 310 can be ensured to maintain the correct path and direction when moving along the axis 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.

[0051] Reference Figure 2 and Figure 3In 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.

[0052] 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.

[0053] 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.

[0054] In one embodiment, the leak-proof and anti-spray connection device 10 also includes a water collection tray, which is positioned opposite the collection trough provided on the outer shell 100 and located at the bottom of the outer shell 100. It is understood that if the connection device leaks, the leaked liquid will be collected by the outer shell 100. The cooling liquid from each part of the outer shell 100 is collected in the collection trough and then merged into the collection tray below the cabinet. This prevents the liquid from spreading outside the device or polluting the environment. Workers can easily remove the collection tray for cleaning without having to disassemble or move the entire device.

[0055] Figure 1 and Figure 3In 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 is connected to 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 leak-proof connection cavity 110. It will be understood that the drain trough 420 is connected to 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 inside 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 leak-proof connection cavity 110. Leaked liquid can be quickly collected by the drain trough 420 and discharged into the leak-proof connection cavity 110, thereby reducing the risk of liquid leaking into the external environment.

[0056] 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, which 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 leak-proof connection cavity 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.

[0057] Reference Figure 1 In one embodiment, the anti-leakage and anti-spray connection 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 connection device, thereby reducing maintenance costs. The outer shells 100 can be manufactured, transported and stored independently, and the modular design makes the connection device easy to expand and maintain.

[0058] The present invention also proposes a cold liquid cabinet, which includes the above-mentioned anti-leakage and anti-spray connection device 10. The specific structure of the anti-leakage and anti-spray connection device 10 refers to the above-mentioned embodiment. Since the cold liquid cabinet adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, rather than to limit it. Although this application has been described in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above-mentioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
