A water distributor for liquid cooling cabinet

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310842719.9 and application date of July 10, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the technical field of liquid cooling equipment, and in particular to a water distributor for a liquid cooling cabinet. Background Art

[0004] Cold plate liquid cooling is the mainstream liquid cooling technology. Its working principle is to add a cold plate inside the server, which is connected to the server's chips, GPUs, and other heat-generating components through pipes. Coolant flows through the connected pipes, and through the heat exchange components on the cold plate, the coolant absorbs and removes heat from the heat-generating components. A cold plate liquid cooling cabinet primarily consists of liquid cooling pipes, a water distributor, a cooling distribution unit (CDU), and related connecting parts.

[0005] In existing technology, liquid-cooled cabinet manifolds are typically full-size, with inlet and outlet lines connected to their respective main lines, which then connect to the CDU. Cold-plate liquid-cooled cabinets typically have a single manifold. Due to the varying heights of individual servers, the type and size of the servers in the cabinet must be determined in advance before customizing the manifold. For example, 2U, 3U, or 4U servers require increased spacing between manifold branches. This reduces the cabinet's flexibility, forcing a single cabinet to accommodate only servers of the same size or requiring the location and number of servers of different sizes to be determined in advance. The types of servers added later to the racks are also limited by the installed manifold.

[0006] Therefore, developing a liquid cooling cabinet water distributor to solve the technical defects of the existing technology, such as poor versatility, complex assembly and easy leakage, has become an urgent problem to be solved by technical personnel in this field.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0040] In this application, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.

[0043] Please refer to Figure 1. An embodiment of the present application provides a liquid cooling cabinet water distributor, including: a pipeline main body 1, a liquid outlet joint 2 and a liquid inlet joint 3. The pipe wall of the pipeline main body 1 is provided with a branch pipeline joint 4 for externally connecting a heat exchange unit; one end of the liquid outlet joint 2 and one end of the liquid inlet joint 3 are respectively connected to the two ends of the pipeline main body 1, and the other end of the liquid outlet joint 2 and the other end of the adjacent liquid inlet joint 3 can be plugged into each other; when the liquid outlet joint 2 and the liquid inlet joint 3 are plugged into, the liquid outlet joint 2 and the liquid inlet joint 3 are connected; the liquid outlet joint 2 and the liquid inlet joint 3 are self-sealing joints.

[0044] In the technical solution provided by the embodiments of this application, the liquid inlet connector 3 of a liquid-cooled cabinet water distributor is connected to the liquid outlet connector 2 of an adjacent liquid-cooled cabinet water distributor. The liquid inlet connector 3 of the adjacent liquid-cooled cabinet water distributor is then connected to the liquid outlet connector 2 of another liquid-cooled cabinet water distributor. This end-to-end connection completes the entire water distribution pipeline. At this point, liquid flows through the liquid outlet connector 2 and the liquid inlet connector 3, achieving flow communication, and then passes through the CDU for cooling.

[0045] When the liquid inlet connector 3 or the liquid outlet connector 2 at both ends of the pipeline body are not plugged in, since both the liquid outlet connector 2 and the liquid inlet connector 3 are self-sealing structures, the liquid will be confined inside the liquid cooling cabinet water distributor and will not flow out.

[0046] In the actual application process, the modular splicing method can be adopted according to the actual use requirements, and the entire water distribution pipeline can be built simply and conveniently like "building blocks"; at the same time, due to its simple structure, it will occupy less space than the traditional water distribution pipeline structure, and disassembly and operation and maintenance will be more convenient.

[0047] If server requirements change, the modular liquid cooling cabinet water distributors allow for flexible installation and disassembly. When a liquid cooling cabinet water distributor is removed, both the outlet connector 2 and the inlet connector 3 automatically seal, allowing for disassembly without shutting down the server. Once server requirements are complete, simply replace the water distributor module with one that matches the server's specifications.

[0048] Compared with the water distributor in the prior art, the modular liquid cooling cabinet water distributor has the following advantages: First, the water distributor is modular in form and can be disassembled and assembled at will, and the disassembly and assembly process is simple and quick, which can greatly reduce the operation and maintenance cost; Second, more diversified modules can be built according to actual usage needs without customization, and can be flexibly matched according to actual business conditions to meet the needs, greatly reducing the installation cost; Third, most of the water distributors in the prior art are equipped with centralized modules and branch modules, and are connected by connecting plugs. Such a complex structure will greatly increase the incidence of leakage. The connection principle of the technical solution of this application is different from the prior art. There are no complex connecting parts and the probability of leakage is greatly reduced.

[0049] Please refer to Figures 7 and 8, which illustrate an application scenario of a water distribution pipeline constructed by connecting modular liquid cooling cabinet water distributors end to end in the technical solution provided in the embodiment of this application. However, the applicant emphasizes that this is only a specific illustration of one application scenario of the technical solution of this application and does not constitute a limitation on the protection scheme of this application.

[0050] Please refer to Figures 3 to 5 here, where the structures of the liquid outlet connector 2 and the liquid inlet connector 3 will be specifically explained in combination with the exploded view of the liquid outlet connector 2 and the liquid inlet connector 3, as well as the cross-sectional view after the two are connected.

[0051] In the description of the embodiments of the present application, the first elastic member 10 and the second elastic member 17 may be springs or other types of elastic components, which will not be described in detail later.

[0052] In one embodiment, the liquid inlet connector 3 includes: a movable valve core 8, a first valve body 9, a first elastic member 10 and a first positioning ring 11. The first valve body 9 is a hollow structure. The first positioning ring 11 is located inside the first valve body 9 and is fixedly arranged at one end of the first valve body 9 connected to the pipeline main body 1. The movable valve core 8 can move inside the first valve body 9. The two ends of the first valve body 9 are respectively connected to the movable valve core 8 and the first positioning ring 11. The first elastic member 10 is arranged inside the first valve body 9. The two ends of the first elastic member 10 respectively abut the movable valve core 8 and the first positioning ring 11. The movable valve core 8 and the first valve body 9 cooperate to block or conduct the liquid inlet connector 3.

[0053] In the structure of the liquid inlet connector 3, it is connected to the pipeline body 1 through the outer wall of the first valve body 9. When the liquid inlet connector 3 is not subjected to external pressure, the first elastic member 10 acts to seal the movable valve core 8 against the outside of the first valve body 9. At this time, the connection surface between the movable valve core 8 and the outer side of the first valve body 9 is closed, thus blocking the liquid flowing through the interior of the first valve body 9. The first positioning ring 11 abuts against the other end of the first elastic member 10 to ensure that the first elastic member 10 is only compressed under external force, preventing the first elastic member 10 from moving under external force.

[0054] The liquid outlet joint 2 includes: a movable sealing member 13, a valve stem 14, a second valve body 16, a second elastic member 17 and a second positioning ring 18. The second valve body 16 is a hollow structure. The second positioning ring 18 is located inside the second valve body 16 and is fixedly arranged at one end of the second valve body 16 connected to the pipeline body 1. The valve stem 14 is a structure in which the cross-sectional area at both ends is larger than the cross-sectional area in the middle. The movable sealing member 13 is a hollow structure. The valve stem 14 is fixedly arranged inside the second valve body 16. One end of the valve stem 14 abuts against the second positioning ring 18, and the other end is in a movable sealing member. The second elastic member 17 is arranged between the two end surfaces of the valve stem 14, and one end of the second elastic member 17 abuts against the movable seal 13, and the other end of the second elastic member 17 abuts against the end surface of the valve stem 14 abutting against the second positioning ring 18. The cross section of the movable seal 13 is the same as the cross section of the first valve body 9. The movable seal 13 can move between the two end surfaces of the valve stem 14. The movable seal 13, the valve stem 14 and the second valve body 16 cooperate to seal or conduct the liquid outlet joint 2.

[0055] In the structure of the liquid outlet connector 2, it is connected to the pipeline body 1 via the outer wall of the second valve body 16. When the liquid outlet connector 2 is not subjected to external pressure, the second elastic member 17 acts to seal the movable sealing member 13 against the outer side of the second valve body 16. At this time, the connection surface between the movable sealing member 13 and the outer side of the second valve body 16 is closed, thus blocking the liquid flowing through the interior of the second valve body 16. The second positioning ring 18 abuts against the other end of the second elastic member 17 to ensure that the second elastic member 17 is only compressed under external force, preventing the second elastic member 17 from moving under external force.

[0056] The above structural introduction, combined with the structure of the explosion diagram, explains the self-sealing principle of the liquid inlet connector 3 and the liquid outlet connector 2 respectively. Next, when the liquid inlet connector 3 and the liquid outlet connector 2 are plugged in, the principle of liquid circulation after plugging in is explained in combination with the characteristics of each structure.

[0057] During plugging, the valve stem 14 and the second valve body 16 can enter the cavity of the first valve body 9 , and the valve stem 14 pushes the movable valve core 8 to move toward the interior of the first valve body 9 .

[0058] At the beginning of the plugging, when the liquid outlet connector 2 contacts the liquid inlet connector 3, force is continued to be applied, and the end faces of the liquid outlet connector 2 and the liquid inlet connector 3 are squeezed. At this time, the movable sealing member 13 of the liquid outlet connector 2 is acted upon by the first valve body 9 and moves toward the direction of the second positioning ring 18. The second spring 17 of the liquid outlet connector 2 is therefore compressed, and the cavity of the first valve body 9 of the liquid inlet connector 3 enters into the second valve body 16 of the liquid outlet connector 2. At the same time, under the action of the valve stem 14 of the liquid outlet connector 2, the movable valve core 8 of the liquid inlet connector 3 will move toward the direction of the first positioning ring 11, and the first spring 10 of the liquid inlet connector 3 will also be compressed, and the valve stem 14 of the liquid outlet connector 2 will enter into the cavity of the first valve body 9 of the liquid inlet connector 3.

[0059] At this time, the entire liquid flow channel is opened, and the liquid first enters the liquid outlet joint 2 through the pipeline body 1 to the second valve body 16 cavity, and then flows into the first valve body 9 cavity of the liquid inlet joint 3 through the cavity generated at the contact point of the liquid outlet joint 2 and the liquid inlet joint 3, realizing the circulation of the liquid. The whole process is shown by the arrows in Figure 5.

[0060] To further optimize the technical solution, the shape of the valve stem 14 is a structure in which the cross-sectional area at one or two ends is larger than the cross-sectional area in the middle. The connecting end of the valve stem 14 and the second elastic member 17 is provided with an end disc with a through hole, and the through hole is used for the circulation of liquid. The structure with large cross-sectional areas at both ends of the valve stem 14 can increase the contact area between the two ends of the valve stem 14 and the movable seal 13 and the second spring 17, which can prevent the various components from slipping during the end face extrusion process; at the same time, the structure with a small cross-sectional area in the middle of the valve stem 14 forms a larger capacity cavity between the valve stem 14 and the second valve body 16, which can speed up the passage of liquid; further, the connecting end of the valve stem 14 and the second elastic member 17 is provided with an end disc with a through hole, through which liquid can flow, which can ensure the rapid passage of liquid and a large contact area to prevent slipping.

[0061] To further optimize the technical solution, in order to effectively improve the airtightness of the self-sealing structure of the liquid inlet connector 3 and prevent liquid outflow, in the technical solution provided in the embodiment of the present application, the liquid inlet connector 3 also includes: a first sealing ring 7, and the first sealing ring 7 is arranged at the connection between the movable valve core 8 and the first valve body 9.

[0062] Similarly, in order to effectively improve the airtightness of the self-sealing structure of the liquid outlet joint 2 and prevent liquid from flowing out, in the technical solution provided in the embodiment of the present application, the liquid outlet joint 2 includes: a second sealing ring 12 and a third sealing ring 15, the second sealing ring 12 is arranged at the connection between the movable sealing member 13 and the valve stem 14, and the third sealing ring 15 is arranged in the gap between the valve stem 14 and the second valve body 16.

[0063] Please refer to Figure 6 here. In order to further effectively enhance the connection tightness between adjacent pipeline bodies 1, while also taking into account the practical use requirements of convenient disassembly and assembly, in the technical solution provided by the embodiment of the present application, a latch 19 is provided at one end of the pipeline body 1, and a slot 20 is provided at the other end of the pipeline body 1. The connection between the latch 19 and the slot 20 is used to fix the liquid outlet connector 2 and the liquid inlet connector 3. The latch 19 can be inserted into the slot 20 of the pipeline body 1 of the adjacent liquid cooling cabinet water distributor. The structural design of the latch 19 and the slot 20 allows for quick disassembly and assembly; at the same time, the installation of the latch 19 and the slot 20 is achieved by relying on the insertion connection relationship, which can effectively shorten the connection gap between adjacent pipeline bodies 1 and enhance the connection tightness between adjacent pipeline bodies 1.

[0064] To further optimize the technical solution, in the technical solution provided in the embodiment of the present application, the latch 19 and the slot 20 are staggered. This staggered structural design allows the latch 19 to be inserted into the slot 20 by slightly twisting the pipe body 1 of the liquid cooling cabinet water distributor, thereby locking the latch 19 and the slot 20. This eliminates the need for external reinforcement structures such as locks, simplifies the installation process, and makes the overall structure more compact and lightweight after installation.

[0065] At the same time, on the basis of taking into account the tight connection of adjacent pipeline bodies 1, and taking into account the design concept of simple structural design and improved installation efficiency, in the technical solution provided in the embodiment of the present application, the number of clips 19 set on one end of the pipeline body 1 is 4, and adjacent clips 19 are set at equal intervals; the number of slots 20 set on the other end of the pipeline body 1 is 4, and adjacent slots 20 are set at equal intervals; the clips 19 correspond one to one to the slots 20.

[0066] In other implementation scenarios, to further expand the application scenarios of the liquid cooling cabinet water distributor and facilitate the connection of the liquid cooling cabinet water distributor with other possible connectors, the technical solution provided in the embodiments of the present application provides a detachable connection between the pipe body 1 and the liquid inlet connector 3, and a detachable connection between the pipe body 1 and the liquid outlet connector 2. Depending on the application scenario and usage requirements, the pipe body 1 can be detached from the liquid outlet connector 2 and / or the liquid inlet connector 3 to connect other components.

[0067] In order to facilitate the disassembly and installation of the liquid outlet connector 2 and / or the liquid inlet connector 3 from the pipeline main body 1, and at the same time, to ensure a more stable connection with the pipeline main body 1, in the technical solution provided in the embodiment of the present application, the liquid outlet connector 2 and the liquid inlet connector 3 are connected to the pipeline main body 1 through threads.

[0068] Referring to Figure 2 , when the pipe body 1 and the liquid outlet connector 2 and / or the liquid inlet connector 3 are detachable, the liquid cooling cabinet water distributor further includes a sealing connector 5 to further optimize the sealing effect at the ports. The sealing connector 5 can be connected to either end of the pipe body 1. When the sealing connector 5 is externally connected to the ports of the liquid cooling cabinet water distributor, the technical effect of a closed-port liquid cooling cabinet can be achieved.

[0069] Similarly, a liquid cooling cabinet water distributor provided in an embodiment of the present application also includes: a connecting joint 6, which is used to fix multiple pipe bodies during transportation, one end of the connecting joint 6 is connected to the pipe body 1, and the other end of the connecting joint 6 is connected to the adjacent pipe body 1, which has the advantages of easy installation and convenient disassembly.

[0070] From the above technical solution, it can be concluded that the liquid cooling cabinet water distributor provided in the embodiment of the present application has the following advantages:

[0071] 1. The liquid cooling cabinet water distributor provided in the embodiment of the present application has modular characteristics and can be flexibly adjusted according to the actual business situation and the size, model, and height of the server, thereby enabling the simultaneous racking of servers of multiple sizes and greater versatility.

[0072] 2. The modular water distributor can be disassembled and assembled according to actual needs, and the disassembly and assembly process is simple and quick. The flow channel can be connected after installation, and the flow channel will be closed immediately after separation, effectively reducing the probability of leakage;

[0073] 3. Furthermore, the system can be installed while the server is running without shutting down the server. At the same time, it will not affect the installed water distributors and servers, significantly reducing operation and maintenance costs.

[0074] 4. The detachable design of the liquid outlet and liquid inlet connectors makes them more versatile and can be flexibly adjusted according to the actual installation scenario. They are compatible with servers with different interface types and do not require customization of the entire machine.

[0075] 5. Both ends of the pipeline body can be installed with liquid outlet joints and liquid inlet joints, as well as connecting joints for connecting to the CDU pipeline, or sealing joints to achieve sealing of the top end pipeline. An exhaust valve can also be installed to exhaust the air in the pipeline. It can be flexibly adjusted according to actual conditions.

[0076] To summarize, an embodiment of the present application provides a liquid cooling cabinet water distributor, comprising: a pipeline main body, a liquid outlet joint and a liquid inlet joint, the pipe wall of the pipeline main body being provided with a plurality of branch pipeline joints for externally connecting a heat exchange unit; one end of the liquid outlet joint and one end of the liquid inlet joint are respectively connected to the two ends of the pipeline main body, and the other end of the liquid outlet joint and the other end of the liquid inlet joint of an adjacent liquid cooling cabinet water distributor can be plugged into each other; when the liquid outlet joint and the liquid inlet joint are plugged in, the liquid outlet joint and the liquid inlet joint are connected; the liquid outlet joint and the liquid inlet joint are self-sealing joints. In the technical solution provided in the embodiment of the present application, when the liquid inlet connector and the liquid outlet connector are not plugged in, they are in a self-sealing state and the internal liquid cannot flow out; when the two are plugged in, the flow of the liquid can be connected. Therefore, when building the water distributor structure, no other components are required to complete the construction, and the installation is simple and convenient; at the same time, it can be spliced ​​according to actual usage requirements without the need to customize a specific template, and it has strong versatility; thirdly, the use of complex connection structures is reduced, which can effectively reduce the leakage problem caused by damage to the connection of complex connectors.
