Description

Technical Field

[0001] This utility model relates to the field of cabinet heat dissipation technology, and in particular to a cabinet and its water distribution unit. Background Technology

[0002] Currently, one method for cooling equipment (such as servers) within server racks is liquid cooling. This involves installing liquid cooling pipes and liquid cooling terminals (such as cold plates) connected to these pipes within the rack. A power pump draws coolant from the liquid inlet of the liquid cooling pipes into the liquid cooling terminals. The coolant in the terminals exchanges heat with the equipment, and the cooled coolant flows out of the terminals and finally exits from the liquid outlet of the liquid cooling pipes. This cycle continues, cooling the equipment within the rack. For racks using liquid cooling technology, a manifold is often installed at the rear of the rack to centrally distribute and manage the coolant between the power pump and the equipment. Typically, the male connector of the manifold's inlet pipe connects to the female connector of the liquid cooling pipe on the equipment within the rack, and the male connector of the return pipe connects to the female connector of the equipment's liquid cooling pipe. In addition, to prevent coolant from leaking into the cabinet due to jetting, an anti-jet box can be installed on the manifold, and the two male terminals of the manifold are located inside the anti-jet box. The two female terminals of the liquid cooling pipeline need to extend into the anti-jet box and connect to the two male terminals one by one.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:

[0004] The anti-jet box is fixed on the manifold. The two female connectors of the liquid cooling pipeline need to be inserted into the anti-jet box and blindly connected to the two male connectors. This may result in inaccurate or inconvenient connections. Utility Model Content

Detailed Implementation

[0056] This utility model discloses a water manifold for liquid-cooled cabinets, which can conveniently and effectively realize the centralized distribution of cooling liquid between equipment, improve space utilization, reduce the difficulty of operation for personnel, and thus effectively improve the safety and convenience of cabinet equipment installation and maintenance.

[0057] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0058] The water distribution manifold provided in this embodiment of the utility model is applied to a server rack (liquid-cooled server rack), such as... Figure 1 As shown, it includes the main body of the water distribution manifold and an anti-jet device;

[0059] The jet propulsion device includes: a jet propulsion box 3 and an elastic component;

[0060] like Figure 4 As shown, the anti-spray box 3 is installed in the main body of the manifold, and the inlet male connector 1 and the return male connector 2 of the main body of the manifold pass through the first box wall of the anti-spray box 3 and are located inside the anti-spray box 3. The second box wall of the anti-spray box 3 is provided with an inlet female connector 3.1 and a return female connector 3.2, which are distributed one-to-one with the inlet male connector 1 and the return male connector 2 (i.e., arranged in a one-to-one correspondence). Figure 5 As shown, the anti-spray box 3 can also slide along the inlet male connector 1 and the return male connector 2 towards the main body of the water distributor, so that the inlet male connector 1 and the return male connector 2 protrude out of the anti-spray box 3;

[0061] The elastic component provides elastic restoring force for the sliding of the anti-blowout box 3, so that the anti-blowout box 3 returns to its original position when the inlet male connector 1 and the outlet male connector 2 are located inside the anti-blowout box 3.

[0062] It should be noted that, as Figures 1 to 3 As shown, the main body of the water distribution manifold includes: an adjacent inlet pipe 8 and a return pipe 9, which can be vertically installed at the rear of a cabinet (such as a liquid-cooled cabinet); wherein, as Figure 1 As shown, the water inlet pipe 8 includes: a water inlet pipe body and multiple male water inlet connectors 1 (i.e., male water inlet terminals) spaced apart on the water inlet pipe body. Each male water inlet connector 1 of the water inlet pipe 8 is used for insertion connection with the female water inlet connector (i.e., female water inlet terminal) of the water cooling branch (i.e., liquid cooling branch) of the corresponding heat-dissipating device (e.g., server) in the cabinet. Similarly, the return water pipe 9 includes: a return water pipe body and multiple male return water connectors 2 (i.e., male return water terminals) spaced apart on the return water pipe body. Each male return water connector 2 of the return water pipe 9 is used for insertion connection with the female return water connector (i.e., female return water terminal) of the water cooling branch of the corresponding heat-dissipating device. Figure 1As shown, several pairs or groups of male connectors (including male inlet connector 1 and male return connector 2) are arranged side by side on the inlet pipe 8 and the return pipe 9, and are used to connect the pairs of female connectors of the water cooling branch of several heat dissipation equipment in the same cabinet.

[0063] In addition, such as Figure 3 As shown, the lower part of the inlet pipe 8 is provided with an inlet 20 for connecting to an external liquid inlet pipe, and the lower part of the return pipe 9 is provided with an outlet 21 for connecting to an external liquid return pipe, thus forming a complete coolant circulation loop. The function of the inlet pipe 8 is to distribute the low-temperature coolant from the external liquid inlet pipe to the water-cooling branches of each device to be cooled, and then the water-cooling branches deliver the low-temperature coolant to the liquid-cooling terminals (e.g., cold plates) of the corresponding devices to meet the continuous cooling requirements of the devices. The function of the return pipe 9 is to collect the high-temperature coolant flowing from each liquid-cooling terminal and deliver it to the external liquid return pipe to realize the return of coolant from the liquid cooling system. Additionally, as... Figure 3 As shown, the lower back of both the inlet pipe 8 and the return pipe 9 can be equipped with a quick-connect fitting 25, which can be connected to an external pipeline to drain the liquid accumulated at the bottom of the pipe when necessary; that is, this manifold can be installed vertically at the rear of the liquid cooling cabinet to connect the main liquid supply line (i.e., the aforementioned inlet and return pipes) and the water cooling branch lines of multiple devices to be cooled in the cabinet, so as to realize the connection between the main liquid supply line and the multiple devices to be cooled in the cabinet, and to facilitate and effectively realize the centralized distribution of cooling liquid between the devices;

[0064] Furthermore, the second wall of the anti-spray box 3 is distributed opposite to the first wall; the ports of the inlet male connector 1 and the return male connector 2 respectively penetrate the first wall of the anti-spray box 3 and are both located inside the anti-spray box 3, that is, the ports of the inlet male connector 1 and the return male connector 2 extend into the anti-spray box 3, which is equivalent to the anti-spray box 3 being fitted onto the outside of the ports of the inlet male connector 1 and the return male connector 2, so that the ports of the inlet male connector 1 and the return male connector 2 are both covered (surrounded); the inlet female connector 3.1 of the second wall of the anti-spray box 3 is distributed opposite to the port of the inlet male connector 1, and the return female connector 3.2 is also distributed opposite to the port of the return male connector 2. In this way, when the anti-spray box 3 is pressed (pressed) and slides along the inlet male connector 1 and the return male connector 2 close to the main body of the manifold, the inlet male connector 1 and the return male connector 2 can both extend out of the anti-spray box 3 through the corresponding female connector ports, thus facilitating... The inlet female connector of the water-cooling branch of the equipment to be cooled is connected to the inlet male connector 1, and the return female connector is connected to the return male connector 2. This not only improves the accuracy of the connection between the paired female connectors and the paired male connectors, but also makes it easier for personnel to insert the above-mentioned paired male and female connectors, reducing the difficulty of personnel operation. This helps to improve the convenience of connecting the manifold to the water-cooling branch of the equipment to be cooled. Moreover, after the pressing force is removed, based on the elastic restoring force provided by the elastic component, after the paired male and female connectors are inserted and connected, the anti-spray box 3 can be reset so that the inlet male connector 1 and the return male connector 2 are located in the anti-spray box 3. That is, it forms a cover at the connection point (i.e., the connection part) of the paired male and female connectors. Even if coolant spray occurs, it can effectively prevent coolant from leaking into the cabinet, playing the role of preventing coolant spray. This can effectively avoid damage to the equipment in the cabinet, thereby effectively ensuring the safety of the equipment in the cabinet.

[0065] Of course, the inlet female connector can also be inserted into the anti-jet box 3 through the inlet female connector port 3.1 and then plugged into the inlet male connector 1; the return female connector can also be inserted into the anti-jet box 3 through the return female connector port 3.2 and then plugged into the return male connector 2; among them, such as Figure 4 As shown, both the inlet female connector 3.1 and the return female connector 3.2 can be circular openings, and their shapes can be adapted to the shape of the inlet male connector 1 or the return male connector 2, ensuring that the inlet male connector 1 and the return male connector 2 can be smoothly extended and retracted. At the same time, they can also be adapted to the shape of the inlet female connector or the return female connector, ensuring that the inlet female connector and the return female connector can be smoothly inserted and removed.

[0066] In other words, the anti-spray box 3 of this manifold is a movable anti-spray box with elastic support, and it can slide along the length of the inlet male connector 1 and the return male connector 2. This can be used to adjust the position of the anti-spray box 3 relative to the inlet male connector 1 and the return male connector 2, so that the inlet male connector 1 and the return male connector 2 can protrude out of the anti-spray box 3, which facilitates connection with the corresponding female connector. Moreover, based on the function of the elastic component, the anti-spray box 3 can also elastically return to the position of covering the connection of the paired male and female connectors. This not only improves the accuracy of the connection of the paired male and female connectors, but also makes it easier for personnel to insert the paired male and female connectors, reducing the difficulty of personnel operation. This can help improve the accuracy and convenience of the connection between the manifold and the water cooling branch of the equipment to be cooled, and at the same time, it can effectively ensure the safety of the equipment in the cabinet.

[0067] In addition, the anti-jet device can also use an openable and closable anti-jet cover; of course, when the inlet female connector and the return female connector are separated from the inlet male connector 1 and the return male connector 2 one by one (pulled out), the anti-jet box 3 can also cover (enclose) the inlet male connector 1 and the return male connector 2, that is, the anti-jet box 3 can play the role of anti-jet when inserting or pulling out the male and female connectors; and as mentioned above, the male connectors of the manifold can be in multiple sets or pairs, so the number of anti-jet devices is also multiple, and can correspond one-to-one with multiple sets of paired male connectors.

[0068] Furthermore, the anti-jet device also includes a guide assembly;

[0069] The guide component is located on the main body of the manifold and is arranged parallel to the inlet male connector 1 or the return male connector 2;

[0070] The anti-spray box 3 is slidably mounted on the guide assembly and has a switchable first station and a second station. When the anti-spray box 3 is in the first station, the water inlet male connector 1 and the water return male connector 2 are located inside the anti-spray box 3. When the anti-spray box 3 is in the second station, the water inlet male connector 1 and the water return male connector 2 protrude outside the anti-spray box 3.

[0071] The elastic component provides elastic restoring force to allow the anti-jet box 3 to elastically return to the first position.

[0072] It should be noted that, as Figure 7As shown, both the inlet male connector 1 and the return male connector 2 can be columnar structures. The guide component can be located between the inlet male connector 1 and the return male connector 2, or on the same side of the inlet male connector 1 and the return male connector 2, and parallel to the inlet male connector 1 or the return male connector 2. This allows the sliding direction of the anti-spray box 3 to be parallel to the length direction of the inlet male connector 1 or the return male connector 2, effectively allowing the anti-spray box 3 to slide along the inlet male connector 1 and the return male connector 2. The guide component provides sliding guidance for the anti-spray box 3, thereby adjusting the position of the anti-spray box 3 relative to the inlet male connector 1 and the return male connector 2, so that the inlet male connector 1 and the return male connector 2 are either located inside the anti-spray box 3 or protrude outside the anti-spray box 3. Of course, the anti-spray box 3 can be slid from the first position to the second position by pressing, and based on the action of the elastic component, the anti-spray box 3 can be elastically slid back to the first position from the second position. The elastic component can be located between the anti-spray box 3 and the main body of the manifold.

[0073] Among them, such as Figure 4 As shown, the first station of the anti-spray box 3 is equivalent to the connector covering station, meaning that at this station, both the inlet male connector 1 and the return male connector 2 are located inside the anti-spray box 3; as Figure 5 As shown, the second position of the anti-spray box 3 is equivalent to the connector protrusion position. In this position, both the inlet male connector 1 and the return male connector 2 protrude from the anti-spray box 3 through their corresponding female connector ports. This facilitates direct connection between the inlet female connector and the return female connector and the inlet male connector 1 and the return male connector 2. Moreover, after the pressing force is removed, the anti-spray box 3 can elastically return to the first position based on the action of the elastic component. At this time, the connection of the paired male and female connectors is still covered. Of course, the anti-spray box 3 has a limit in both the first and second positions. In addition, during the process of the anti-spray box 3 sliding to the second position under pressure, the inlet female connector and the return female connector can also extend into the anti-spray box 3 and connect with the corresponding male connector. At this time, the connection of the paired male and female connectors is still located inside the anti-spray box 3.

[0074] In other words, by adding a guide component to this anti-jet device, not only can the anti-jet box 3 be provided as the main body for installation, but the anti-jet box 3 can also be guided along the sliding of the inlet male connector 1 and the return male connector 2, so as to ensure that the anti-jet box 3 slides smoothly and reliably.

[0075] Furthermore, such as Figure 6 As shown, the guide assembly includes: a guide pin base 7 and a guide pin assembly 6;

[0076] The guide pin base 7 is located between the inlet pipe 8 and the return pipe 9 of the main body of the water distributor;

[0077] The guide pin assembly 6 is located on the guide pin base 7, between the inlet male connector 1 and the return male connector 2, and passes through the anti-spray box 3;

[0078] The anti-spray box 3 can slide along the guide pin assembly 6;

[0079] The elastic component is positioned between the guide pin base 7 and the anti-spray box 3.

[0080] It should be noted that, as Figure 8 As shown, the inlet pipe 8 and the return pipe 9 are connected and fixed by multiple fixing blocks 18, and several reinforcing blocks 17 are also provided between the inlet pipe 8 and the return pipe 9; of course, the reinforcing blocks 17 and the fixing blocks 18 are staggered one-to-one; as shown Figure 8 As shown, the guide pin base 7 is installed between the inlet pipe 8 and the return pipe 9, and rests on the fixing block 18. It is connected and fixed to the reinforcing block 17 by the guide pin base fixing screw 24, so that the guide pin base 7 is fixed between the inlet pipe 8 and the return pipe 9. The guide pin assembly 6 can be easily installed between the inlet pipe 8 and the return pipe 9 through the guide pin base 7, ensuring that the guide pin assembly 6 is stable and reliable. Moreover, both the guide pin assembly 6 and the elastic assembly are installed between the inlet male connector 1 and the return male connector 2, which can avoid occupying other space in the manifold, making the structure of the manifold more compact. In addition, the design of the guide pin assembly 6 and the elastic assembly also makes the guiding and sliding of the anti-spray box 3 easier.

[0081] Specifically, such as Figure 5 As shown, the guide pin assembly 6 includes multiple guide pins 6.1;

[0082] The elastic component includes multiple springs;

[0083] Multiple springs are fitted onto multiple guide pins 6.1 and abut against the guide pin base 7 and the anti-spray box 3 respectively.

[0084] It should be noted that multiple guide pins 6.1 are arranged in parallel on the guide pin base 7, and are all located between the inlet male connector 1 and the return male connector 2 and penetrate the anti-spray box 3; among them, such as Figure 5 As shown, the number of guide pins 6.1 can be two, meaning the anti-spray box 3 can slide along two guide pins 6.1, that is, the anti-spray box 3 can slide along the double guide pins, which makes the guiding sliding of the anti-spray box 3 more stable; wherein, as Figure 6 As shown, two guide pins 6.1 can be installed on the guide pin base 7 and fixed by guide pin fixing screws 23; wherein, as Figure 7As shown, the guide pin base 7 may have two holes for installing two guide pins 6.1. The two guide pin fixing screws 23 are then fixed to the two guide pins 6.1 from the back of the guide pin base 7. Alternatively, the two guide pins 6.1 may be screwed onto the guide pin base 7, meaning that the tail of the guide pin 6.1 is machined with external threads and directly screwed into the corresponding hole in the guide pin base 7. In this way, when the guide pin 6.1 needs to be disassembled, it can be disassembled by simply rotating it. In addition, the guide pin base 7 may be a metal strip.

[0085] In addition, there are two springs, each fitted onto one of the two guide pins 6.1. One end of each spring can abut against the anti-spray box 3, and the other end can abut against the guide pin base 7, which is used to provide elastic restoring force for the anti-spray box 3 to return to the first position.

[0086] In other words, the guide pin assembly 6 adopts a double guide pin structure, and the elastic component adopts a double spring structure, which can be adapted to the double guide pin structure. This makes the guiding sliding and elastic reset of the anti-spray box 3 simpler. Of course, the independent guide pin base 7 between the inlet pipe 8 and the return pipe 9 also facilitates the disassembly and replacement of the guide pin 6.1, eliminating the need to remove the blind plug connector. Moreover, the height of the male connectors on both sides of the guide pin base 7 can be adjusted by the adapter, which also facilitates the replacement of different models of connectors and improves the compatibility of the manifold.

[0087] Specifically, the guide pin 6.1 is provided with a limiting structure for cooperating with the jet protector box 3, and is used to limit the jet protector box 3 when it slides to the first position;

[0088] like Figure 4 As shown, the anti-jet device also includes a limiting block 10;

[0089] The limiting block 10 is disposed on the anti-spray box 3 and is used to abut against the guide pin base 7 when the anti-spray box 3 slides to the second station.

[0090] It should be noted that, as Figure 4 and Figure 5 As shown, the anti-spray box 3 is far away from the main body of the manifold in the first station and close to the main body of the manifold in the second station. When the anti-spray box 3 slides to the first station, the limiting structure of the guide pin assembly 6 can limit the anti-spray box 3, preventing the anti-spray box 3 from continuing to slide away from the main body of the manifold, thus preventing the anti-spray box 3 from slipping off the guide pin assembly. At the same time, the first station is also used as an extreme stroke position of the anti-spray box 3.

[0091] like Figure 4As shown, the limiting block 10 can be set on the side of the anti-spray box 3 facing the main body of the manifold. When the anti-spray box 3 slides to the second position, the limiting block 10 abuts against the main body of the manifold, thus limiting the anti-spray box 3 and preventing it from sliding further towards the main body of the manifold. This also makes the second position another extreme travel position for the anti-spray box 3. The two ends of the spring can abut between the limiting block 10 and the guide pin base 7. This design ensures that the anti-spray box 3 is limited at both the first and second positions.

[0092] Furthermore, the limiting structure of the guide pin 6.1 includes: a limiting step or limiting ring disposed on the guide pin 6.1, which is used to abut against the inner wall of the first box wall of the anti-spray box 3.

[0093] The limiting step can be set in the middle part of the guide pin 6.1. In fact, the end face of the limiting step is used to abut against the inner wall of the first box wall of the anti-spray box 3. The limiting ring can be sleeved in the middle part of the guide pin 6.1. In fact, the end face of the limiting ring is used to abut against the inner wall of the first box wall of the anti-spray box 3, thereby preventing the anti-spray box 3 from continuing to slide away from the main body of the water distributor. Of course, the limiting structure of the guide pin 6.1 is designed in this way, which is simple in structure and convenient in limiting.

[0094] Furthermore, such as Figure 4 As shown, the anti-jet device also includes: a first inlet cover 4, a second inlet cover 5, a first adjustment component, and a second adjustment component;

[0095] The first cover 4 is openable and closable and is located inside the inlet connector 3.1;

[0096] The second cover 5 is openable and closable and is located inside the return sprue connector 3.2;

[0097] The first adjustment component is located outside the second box wall of the anti-spray box 3 and is used to adjust the opening and closing of the first opening cover 4;

[0098] The second adjustment component is located outside the second box wall of the anti-spray box 3 and is used to adjust the opening and closing of the second cover 5.

[0099] It should be noted that, as Figure 4 As shown, the first cover 4 can adopt a double-cover flip-opening and closing structure; wherein, the first cover 4 may include: two first cover plates, two first torsion springs, and two first rotating shafts; both first cover plates are flipped and disposed inside the inlet connector 3.1 via the first rotating shafts, and the two first cover plates can close the inlet connector 3.1 when they are closed, and the two first torsion springs act on the two first cover plates one by one, so that the two first cover plates are in an elastic closed state, thereby achieving a normal closed state for the inlet connector 3.1; as Figure 5As shown, the first adjustment component can be a first button adjustment component 27; wherein, the first button adjustment component 27 includes: two first arc-shaped pressing buttons, which are respectively disposed on the outer side of the second box wall of the anti-spray box 3 and connected to the corresponding edges of the two first covers; wherein, when the two first arc-shaped pressing buttons are pressed down, they can rotate, thereby driving the two first covers to overcome the elastic force of the first torsion spring and open, thus opening the inlet connector 3.1 to facilitate the insertion of the inlet connector; of course, when the pressure of the two first arc-shaped pressing buttons is removed, the two first covers will automatically be in an engaged state based on the elastic force, thus automatically closing the inlet connector 3.1;

[0100] Similarly, such as Figure 4 As shown, the second cover 5 can adopt a double-cover flip-opening and closing structure; wherein, the second cover 5 may include: two second cover plates, two second torsion springs, and two second rotating shafts; both second cover plates are flipped and disposed inside the return jelly connector 3.2 via the second rotating shafts, and the two second cover plates can close the return jelly connector 3.2 when they are closed, and the two second torsion springs act on the two second cover plates one by one, so that the two second cover plates are in an elastic closed state, thereby achieving a normal closed state for the return jelly connector 3.2; as Figure 5 As shown, the second adjustment component can be a second button adjustment component 28; wherein, the second button adjustment component 28 includes: two second arc-shaped pressing buttons, which are respectively disposed on the outer side of the second box wall of the anti-spray box 3 and connected to the corresponding edges of the two second covers; wherein, when the two second arc-shaped pressing buttons are pressed down, they can rotate, thereby driving the two second covers to overcome the elastic force of the second torsion spring and open, thus opening the return jelly connector 3.2 to facilitate the insertion of the return jelly connector; of course, when the pressure of the two second arc-shaped pressing buttons is removed, the two second covers will automatically be in an engaged state based on the elastic force, thus automatically closing the return jelly connector 3.2.

[0101] In other words, the inner sides of the inlet female connector 3.1 and the return female connector 3.2 of the anti-jet box 3 are respectively provided with openable and closable covers. This not only keeps the anti-jet box 3 in a closed state, preventing any possible leakage from the anti-jet box 3 into the cabinet, but also allows the inlet female connector 3.1 or the return female connector 3.2 to be in an open state through the corresponding adjustment components, thereby facilitating the protrusion of the inlet male connector 1 and the return male connector 2, or the insertion of the inlet female connector or the return female connector. Of course, the design of the above-mentioned covers and adjustment components makes it convenient to open and close the inlet female connector 3.1 and the return female connector 3.2.

[0102] Furthermore, such as Figure 2As shown, there are multiple sets of inlet male connector 1 and return male connector 2, which are distributed vertically on the main body of the water distributor.

[0103] There are multiple anti-jet devices, and each one corresponds to a set of inlet male connectors 1 and return male connectors 2. As mentioned above, the inlet pipe 8 and return pipe 9 of the main body of the water manifold are both arranged vertically. Multiple male inlet connectors 1 are distributed at equal intervals along the vertical direction on the inlet pipe 8, and multiple male return connectors 2 are distributed at equal intervals along the vertical direction on the return pipe 9, and are horizontally aligned with the multiple male inlet connectors 1. The male inlet connectors 1 and return connectors 2 located at the same level constitute a pair or a group of male inlet connectors 1 and male return connectors 2. In other words, the main body of this water manifold is a vertical water manifold, which can improve the space utilization of the water manifold and avoid occupying too much space inside the cabinet. Moreover, there are multiple anti-spray devices, which correspond one-to-one with multiple groups or pairs of male inlet connectors 1 and male return connectors 2. In this way, the connection points of multiple groups or pairs of male and female connectors can be covered, thus playing a role in preventing spraying at the connection points of multiple groups or pairs of male and female connectors.

[0104] Furthermore, such as Figure 4 As shown, all of the multiple anti-spray boxes 3 have drain outlets 3.3;

[0105] like Figure 1 As shown, the main body of the water manifold also has a drain pipe 11 and a water receiving device;

[0106] The drain pipe 11 is installed vertically on one side of the inlet pipe 8 or return pipe 9 of the main body of the water distributor, and has multiple water receiving structures.

[0107] The multiple water-receiving structures of the drain pipe 11 are located below the drain outlets 3.3 of the multiple anti-spray boxes 3;

[0108] The water receiving device is located at the lower end of the drain pipe 11.

[0109] It should be noted that, as Figure 4 As shown, multiple anti-spray boxes 3 all have drain outlets 3.3; as Figure 1 As shown, the drain pipe 11 is vertically arranged on one side of the return pipe 9, and its multiple water-receiving structures can all be water-receiving funnels 14; among them, such as Figure 6 As shown, the water receiving funnel 14 can be a water receiving box structure; such as Figure 4As shown, the multiple water-receiving funnels 14 of the drain pipe 11 can be located below the drain outlets 3.3 of the multiple anti-spray boxes 3, so that the leakage liquid in the multiple anti-spray boxes 3 can be discharged into the drain pipe 11 together, and then discharged into the water-receiving device through the drain pipe 11. That is, the leakage liquid collected by the drain pipe 11 flows down the pipe body into the water-receiving device, thereby cleaning the leakage liquid in the multiple anti-spray boxes 3 and preventing the leakage liquid from accumulating in the anti-spray boxes 3; wherein, as Figure 2 As shown, the water receiving device can be a water receiving tray 15;

[0110] like Figure 2 As shown, the lower end of the drain pipe 11 is also provided with a sensor placement box 16 for placing sensors. The sensors are used to detect whether there is liquid accumulation in the water receiving tray 15. When there is liquid accumulation in the water receiving tray 15, it will be detected by the sensor in the side sensor placement box 16, thereby triggering an alarm to remind maintenance personnel to clean it. In addition, the drain pipe 11 can be fixed to the outside of the return water pipe 9 by a hook, which makes the installation convenient and quick. Moreover, all the leaks of the anti-spray boxes 3 share a drain pipe 11, which is beneficial to control manufacturing costs.

[0111] In addition, the structure of drain pipe 11 can be referred to Figure 4 As shown, a plurality of openings are provided at vertical intervals on one side wall of the drain pipe 11, and a plurality of water-receiving funnels 14 are respectively arranged at the plurality of openings on the side wall of the drain pipe 11 (e.g. Figure 6 As shown, the water receiving funnel 14 is also connected to the pipe body via the rivet 22. Moreover, one end of the water receiving funnel 14 extends upward separately to provide a rivet hole, preventing the rivets on both sides of the water receiving funnel 14 from rotating due to being on the same axis or having the axes too close together.

[0112] Drain pipe 11, as the third pipe, is arranged in parallel with the inlet pipe 8 and return pipe 9. It is fixed to the return pipe 9 by means of a hook. These three pipes can be fixed by a fixing block and the cabinet beam, so that the water distribution unit can be fixedly installed in the cabinet.

[0113] Furthermore, it should be noted that when the device to be cooled (such as a server node) presses down on the anti-jet box 3, it will first touch the first adjustment button 27 and the second adjustment button 28 to rotate, thereby causing the covers of both openings of the anti-jet box 3 to open, exposing the two male connectors inside the anti-jet box 3. Then, the device to be cooled continues to press down, causing the limiting block to move downwards along with the anti-jet box 3. When the bottom end of the limiting block touches the upper surface of the guide pin base, the anti-jet box 3 is restricted from moving further downwards. At this point, the entire movement stroke ends, and the two female connectors of the water cooling branch of the device to be cooled are connected to the two male connectors of the manifold. Of course, if... Figure 5As shown, at this time, the drain outlet of the anti-spray box 3 will extend into the water receiving funnel of the drain pipe (the drain tank of the heat dissipation equipment will also move to the top of the water receiving funnel), so that all possible leaked liquids will flow into the water receiving tray along the drain pipe.

[0114] In addition, such as Figure 1 As shown, the top of the inlet pipe 8 is sealed with a plug, and the top of the return pipe 9 is equipped with a quick connector 13 for connecting to the air vent valve 12. The air vent valve 12 is connected to the drain pipe 11 through the pipe 26. A small amount of liquid discharged with the air vent valve 12 can be discharged through the drain pipe 11. Of course, this design can ensure that the gas can be discharged smoothly when the manifold is filled with liquid.

[0115] The air vent valve 12 is connected to the top of the return water pipe 9 via a quick connector 13. This avoids the problem of inconsistent valve positions during valve connection, and also... Figure 11 As shown, the quick connector 13 includes a quick-connect male connector 13.1 and a quick-connect female connector 13.2 that can be assembled and connected. The quick-connect female connector 13.2 can be fitted with an internal thread at the tail for direct connection to the exhaust valve 12, which reduces costs and facilitates assembly and disassembly. Of course, the exhaust valve 12 can also be disassembled after liquid injection to save cabinet space.

[0116] In other words, by installing the water manifold provided in this solution at the rear of the cabinet, not only can the liquid cooling pipes be connected to the water cooling branches of each device to be cooled and the internal coolant be circulated, but also any leakage from the male and female connector ports, the device to be cooled, the exhaust valve at the top of the return pipe, etc., can flow out along the drain pipe, preventing any impact on the operation of the equipment inside the cabinet.

Since this solution uses the aforementioned water distribution manifold, it has corresponding beneficial effects, as detailed in the preceding description, which will not be repeated here.
