Description

Technical Field

[0001] This application belongs to the technical field of servers and liquid cooling, specifically relating to a liquid distributor assembly and a liquid cooling cabinet. Background Technology

[0002] In related technologies, the liquid distributor connects to the server via a fluid connector for liquid cooling. To catch any leaks, a leak protection box is installed on the fluid connector to collect and prevent uncontrolled dripping that could cause adverse effects.

[0003] However, the above method requires the leakage protection box to be installed on the outside of the fluid connector, which increases the size of the dispenser and makes it unsuitable for some scenarios with limited installation space, thus limiting the applicability of the dispenser. Utility Model Content The purpose of this application is to provide a liquid dispenser assembly and a liquid cooling cabinet that can solve problems such as the limitation of application scenarios caused by the increase in the size of the liquid dispenser.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a liquid dispenser assembly, including: a liquid dispenser body; The liquid dispenser body includes a first liquid dispensing pipe and a second liquid dispensing pipe, wherein the first liquid dispensing pipe and the second liquid dispensing pipe are spaced apart and a gap is formed between them; The space is used for heat insulation and to receive leaks.

[0005] This application also provides a liquid-cooled cabinet, including the above-mentioned liquid distributor assembly.

[0006] In this embodiment, the first and second dispensing pipes are spaced apart to form a gap. This gap provides insulation between the two pipes, preventing heat exchange. Simultaneously, it also collects leaks to prevent uncontrolled dripping and adverse effects. Compared to related technologies that use a separate leak protection box on the fluid connector, this embodiment eliminates the need for such a box. Instead, it utilizes the dispensing assembly's own structure to collect leaks, reducing the overall size of the dispensing unit and making it suitable for applications with limited space. This broadens the application environment of the dispensing unit. Attached Figure Description

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0012] refer to Figures 1 to 3 This application discloses a coolant distributor assembly 01, applied in the server field, for delivering coolant to servers to achieve a cooling effect. In addition, it can also be used in products such as DC switches, core routing switches, and liquid-cooled cabinets.

[0013] The disclosed distributor assembly 01 includes a distributor body 10, which includes a first dispensing pipe 11 and a second dispensing pipe 12. The first dispensing pipe 11 and the second dispensing pipe 12 are respectively used to transport coolant. Optionally, one of the first dispensing pipe 11 and the second dispensing pipe 12 can be a cold pipe, i.e., used to transport coolant at a lower temperature, and the other can be a hot pipe, i.e., used to transport coolant at a higher temperature. The cold pipe can be used to transport the coolant at a lower temperature to the server to cool it down, and the hot pipe can be used to receive the coolant at a higher temperature that has been discharged from the server and absorbed heat.

[0014] The first liquid distribution line 11 and the second liquid distribution line 12 are spaced apart, forming a gap space M between them. This gap space M is used for heat insulation and receiving leakage.

[0015] It should be noted that since both the first distribution pipe 11 and the second distribution pipe 12 contain coolant, and the temperature of the coolant inside each pipe is different, if the first distribution pipe 11 comes into contact with the second distribution pipe 12, heat exchange will occur between the coolant in the first distribution pipe 11 and the coolant in the second distribution pipe 12. This will cause a change in the temperature of the coolant in the first distribution pipe 11 and the second distribution pipe 12, which will have an adverse effect on the cooling effect and ultimately affect the heat dissipation of the server.

[0016] In this embodiment, the first distribution pipe 11 and the second distribution pipe 12 are separated to prevent heat exchange between the coolant in the first distribution pipe 11 and the second distribution pipe 12, thereby alleviating the problem of coolant temperature change affecting the server's heat dissipation effect.

[0017] Considering that coolant leakage may occur during the operation of the liquid-cooled cabinet, it is necessary to collect the leaked liquid to prevent it from dripping indiscriminately and causing adverse effects.

[0018] In this embodiment, the space M formed between the first liquid distribution pipe 11 and the second liquid distribution pipe 12 can be used to receive the leaked liquid, thereby effectively preventing the leaked liquid from dripping randomly.

[0019] Based on the above configuration, in this embodiment of the application, the first liquid distribution pipe 11 and the second liquid distribution pipe 12 are spaced apart to form a space M. The space M can provide heat insulation between the first liquid distribution pipe 11 and the second liquid distribution pipe 12 to prevent heat exchange between them. At the same time, the space M can also receive leakage to prevent accidental dripping and adverse effects.

[0020] Compared to the method of setting an additional leakage protection box on the fluid connector in related technologies, the embodiment of this application does not require an additional leakage protection box. Instead, it makes full use of the structure of the liquid distributor assembly 01 itself to receive leakage, which can help reduce the overall volume of the liquid distributor and make it suitable for some scenarios with limited installation space, thus making the applicable environment of the liquid distributor no longer limited.

[0021] In some embodiments, the dispenser assembly 01 may further include a partition 20 disposed within the space M to prevent leakage within the space M. The two sides of the partition 20 are connected to the first dispensing line 11 and the second dispensing line 12, respectively, so that the first dispensing line 11, the second dispensing line 12, and the partition 20 together form a liquid guiding channel N.

[0022] Optionally, the partition 20 can extend along the extension direction of the first liquid distribution pipe 11 and the second liquid distribution pipe 12. In this way, a liquid guiding channel N extending along the extension direction of the first liquid distribution pipe 11 and the second liquid distribution pipe 12 can be formed between the first liquid distribution pipe 11, the second liquid distribution pipe 12 and the partition 20, so as to guide the received leakage downstream through the liquid guiding channel N and prevent the leakage from accumulating.

[0023] In some more specific embodiments, the partition 20 can be a long strip plate. Of course, the partition 20 can also be in other forms, which are not specifically limited here.

[0024] An opening may be provided on one side of the liquid channel N for receiving leakage.

[0025] In some more specific embodiments, the liquid guiding channel N can be a concave channel, and the notch of the concave channel is the opening.

[0026] Considering that there is signal transmission around the dispenser assembly 01, in order to alleviate or even prevent signal interference, the partition 20 can be a metal partition. The metal partition can block and shield the signal to prevent the signal from being interfered with and affecting the normal operation of the server.

[0027] Considering that the coolant may contain gas, the gas occupies part of the space in the first distribution pipe 11 or the second distribution pipe 12, resulting in no coolant in that part of the space, which will have an adverse effect on the cooling effect.

[0028] Based on the above configuration, an exhaust valve 13 can be provided at the top of the first liquid distribution pipe 11 or the second liquid distribution pipe 12. The exhaust valve 13 can be used to discharge the gas in the first liquid distribution pipe 11 or the second liquid distribution pipe 12 to prevent the gas from occupying the space of the coolant in the first liquid distribution pipe 11 or the second liquid distribution pipe 12 and affecting the cooling effect.

[0029] It should be noted that, since the density of gas is less than that of coolant, the gas will move upward along the first distribution pipe 11 and the second distribution pipe 12 as it flows with the coolant, and will eventually be discharged through the exhaust valve 13.

[0030] Considering the possibility of coolant leakage from the vent valve 13, the distributor assembly 01 in this embodiment may further include a liquid guide tube 30, one end of which is connected to the vent valve 13 and the other end of which is connected to the spacer space M.

[0031] Based on the above configuration, when coolant leaks outward along the vent valve 13, the coolant leaking from the vent valve 13 can be received through the liquid guide pipe 30 and the leaked liquid can be guided to the interval space M so that the leaked liquid can be guided downstream through the interval space M. This can effectively prevent the coolant leaking from the vent valve 13 from dripping randomly and causing adverse effects.

[0032] It should be noted that since the exhaust valve 13 is located at the top of the first liquid distribution pipe 11 or the second liquid distribution pipe 12, the position of the exhaust valve 13 is higher than the space M. Thus, the coolant leaking from the exhaust valve 13 can flow into the space M along the liquid guide pipe 30 under the action of gravity.

[0033] In some more specific embodiments, the other end of the liquid guide tube 30 can be inserted into the liquid guide channel N and located between the partition plate 20 and the opening of the liquid guide channel N, so that the coolant leaking at the exhaust valve 13 can be mixed with the coolant leaking at other locations (e.g., at the connector 02 described below) and received together through the liquid guide channel N and guided downstream.

[0034] In some embodiments, the distributor assembly 01 can be connected to a server via a connector 02, so that the coolant within the distributor assembly 01 can be delivered to the server via the connector 02 to achieve a cooling effect on the server.

[0035] Considering that leakage may occur in connector 02, server, etc., in order to prevent leakage from dripping down from connector 02, server, etc., the liquid distributor assembly 01 may also include a flow guide 60 for collecting leakage from at least one of the server and connector 02.

[0036] Optionally, a guide 60 can be installed below the area on the server that is prone to leakage, so as to receive and collect the leakage from the server; a guide 60 can also be installed below the area on the connector 02 that is prone to leakage, so as to receive and collect the leakage; of course, guide 60s can also be installed below the areas on the server and the connector 02 that are prone to leakage, so as to receive and collect the leakage from the server and the connector 02 respectively.

[0037] Considering that the volume of the leak collected by the guide member 60 is limited, in order to avoid the overflow of the leak due to the guide member 60 being filled with leak, in this embodiment of the application, a portion of the guide member 60 can be extended into the interval space M to guide the collected leak to the interval space M, thereby effectively preventing the overflow of the leak in the guide member 60.

[0038] To facilitate the flow of collected leaking liquid, the top of the flow guide 60 may be provided with a flow guide groove, which extends partially into the space M, and the bottom wall of the flow guide groove located in the space M may be provided with a first flow guide hole.

[0039] Based on the above configuration, the leakage collected by the guide member 60 can flow along the guide groove toward the space M and flow into the space M through the first guide hole, thereby effectively preventing the leakage from accumulating at the guide member 60 and causing leakage overflow.

[0040] Optionally, the flow guide 60 can be a flow guide plate with a rim around its edge, forming a groove on the upper surface of the flow guide plate to receive leakage from at least one of the server and connector 02.

[0041] The flow channel can be located on the side of the groove near the spacer M and communicate with the groove to guide the leakage collected in the groove into the spacer M.

[0042] In some embodiments, the distributor assembly 01 may further include a splash guard 70, which is used to cover the outside of the connector 021 of the connector 02. In this way, the splash guard 70 can collect the leakage at the connector 021 of the connector 02 to prevent the coolant from spraying out randomly at the connector 021.

[0043] Considering the limited volume of the blowout preventer housing, in order to prevent excessive leakage at the connector 021 of connector 02 from filling the blowout preventer housing, in this embodiment of the application, the wall surface of the blowout preventer housing 70 may be provided with a second guide hole 71. The leakage collected inside the blowout preventer housing 70 can be discharged through the second guide hole 71 to prevent the leakage from filling the blowout preventer housing 70 and causing the blowout preventer housing 70 to deform or even be damaged.

[0044] Considering that the connector 02 is provided with a flow guide 60, which is located below the anti-splash cover 70, the leakage liquid flowing out of the second flow guide hole 71 drips into the flow guide 60, effectively preventing the leakage liquid from dripping randomly and causing adverse effects.

[0045] In some embodiments, the dispenser assembly 01 may further include a leakage collection structure 40 disposed below the spacer space M for collecting leakage from the spacer space M (or, the liquid channel N). In this way, all leakage can be collected by the leakage collection structure 40 to prevent leakage from being discharged randomly.

[0046] Optionally, the leakage collection structure 40 can be a collection tray, collection box, etc., to collect the leakage flowing out of the interval space M through the collection tray or collection box.

[0047] In some embodiments, the dispenser assembly 01 may further include a leakage detection element 50 disposed within the leakage collection structure 40. Based on this, the leakage detection element 50 can detect whether leakage exists within the leakage collection structure 40, as well as the volume of the leakage, to obtain an overall understanding of the leakage situation.

[0048] For example, the leakage detection element 50 can be a leakage sensor, but it can also be other components, as long as they can detect leakage, and the specific form is not limited.

[0049] Based on the aforementioned distributor assembly 01, this application also discloses a liquid-cooled cabinet, which includes the aforementioned distributor assembly 01. Other structures may also be included, which will not be elaborated here.

[0050] In this embodiment, the leakage mainly originates from server leakage, connector 02 leakage, and distributor assembly 01 leakage. The guide member 60 can receive and collect the leakage from the server, the splash shield 70 can collect the leakage from the connector 02, and the liquid guide tube 30 can collect the leakage from the drain valve 13. Furthermore, the leakage from the guide member 60, the splash shield 70, and the liquid guide tube 30 all eventually flow into the interval space M, and finally into the leakage collection structure 40 for collection. At the same time, the leakage detection element 50 detects the leakage in the leakage collection structure 40.

[0051] In summary, the embodiments of this application have the following technical advantages: 1. The liquid dispenser assembly 01 integrates a leakage collection and protection function to improve leakage positioning accuracy. Specifically, the liquid dispenser assembly 01 integrates leakage diversion, leakage collection, and leakage detection functions, and can support multi-level leakage collection and detection.

[0052] 2. The leakage is collected and guided by the gap M between the first liquid distribution pipe 11 and the second liquid distribution pipe 12, eliminating the need for a separate collection structure. This helps to reduce the size of the liquid distributor assembly 02. Specifically, a certain gap is left between the first liquid distribution pipe 11 and the second liquid distribution pipe 12 to form the gap M. The gap M is used to prevent heat exchange and guide the leakage, and it also helps to improve the space utilization rate of the liquid distributor assembly 01.

[0053] 3. Adding a metal partition can both prevent leakage and shield signals, achieving a multi-functional effect and avoiding structural redundancy.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
