Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, specifically to an anti-jet assembly and a liquid cooling cabinet. Background Technology

[0002] Currently, liquid cooling is a common method for dissipating heat from servers within server racks. 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 servers, and the cooled coolant flows out of the terminals and ultimately out of the liquid outlet of the liquid cooling pipes. This cycle continues, cooling the servers within the rack. Because server racks typically contain many servers, to enhance the cooling effect, branch pipes (main pipes, such as manifolds) and multiple branch pipes are often installed. Each branch pipe connects to a specific branch pipe and also to a corresponding liquid cooling terminal to ensure coolant circulation within the terminal. The branch pipes and the shunt pipes are connected by fluid connectors. The shunt pipes are equipped with male connectors, and the branch pipes are equipped with female connectors. The male connectors have a self-sealing function, meaning that when the male connector is separated from the female connector, it can close its own flow path with the cooperation of its internal movable valve core and sealing structure. When the female connector on the branch pipe is inserted into a corresponding male connector on the shunt pipe, the pipe is opened. When the female connector on the branch pipe is separated from a corresponding male connector on the shunt pipe, the pipe is closed (or shut off).

[0003] In the process of developing this application, the inventors discovered at least the following technical problems in the prior art:

[0004] During liquid cooling, impurities inevitably accumulate in the piping. These impurities flow with the liquid in the piping and may adhere to the sealing structure inside the male connector, causing the sealing structure of the male connector to fail. As a result, during the manual separation of the male connector from the corresponding female connector, and after the male connector is separated from the corresponding female connector, liquid may spray out from the male connector, which may spray onto the server in the rack and adversely affect the server. Utility Model Content

[0005] In order to effectively overcome the problems existing in the prior art, the main purpose of this application is to provide an anti-jet component and a liquid-cooled cabinet, which can reduce the situation where liquid sprayed from the male connector is sprayed onto the server inside the cabinet, thereby effectively avoiding adverse effects on the server.

[0036] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a partial structural schematic diagram of the anti-jet assembly provided in an embodiment of this application. Figure 2 for Figure 1 A partial enlarged view at point A. This embodiment discloses a liquid-cooled server rack, which includes a rack body 2, a main pipeline assembly 3, a liquid-cooled server assembly, and a jet shield assembly 1. The rack body 2 has a server placement area. The main pipeline assembly 3 includes multiple male connectors 31 spaced apart along the height direction. The liquid-cooled server assembly includes a server and a heat dissipation device (e.g., a cold plate), and the server is placed in the server placement area. The heat dissipation device can be attached to the server for heat dissipation, and the heat dissipation device includes multiple female connectors 4 for connecting to the male connectors 31. The jet shield assembly 1 is used to separate the server from the main pipeline assembly 3, thereby reducing the possibility of liquid spraying from the male connectors 31 onto the server inside the rack after the male connectors 31 are separated from the corresponding female connectors 4, thus effectively avoiding adverse effects on the server and ensuring normal server operation. It is understood that "multiple" here refers to two or more.

[0037] Specifically, the main pipeline assembly 3 includes a liquid supply main pipeline and a liquid return main pipeline, which are respectively located inside the cabinet 2 and can be situated on the side wall of the cabinet 2. Multiple male connectors 31, spaced apart along the height direction, are connected to the liquid supply main pipeline and the liquid return main pipeline, respectively. The heat dissipation device includes an inlet pipe and a return pipe. The inlet pipe is connected to multiple flexible hoses 5, each hose 5 being connected to a female connector 4 for connecting to the male connector 31 of the liquid supply main pipeline. The return pipe is connected to multiple flexible hoses 5, each hose 5 being connected to a female connector 4 for connecting to the male connector 31 of the return main pipeline. Two sets of anti-spray assemblies 1 are provided; one set is located between the liquid supply main pipeline and the server, and the other set is located between the return main pipeline and the server. The length direction is... Figure 1 The X direction and the width direction are... Figure 1 The Y-direction and the height direction are... Figure 1 The Z direction in .

[0038] During operation, the coolant in the supply equipment flows from the main supply pipe through the male connector 31, the female connector 4, and the hose 5 into the heat dissipation device. After exchanging heat with the server, the coolant flows back to the supply equipment from the return pipe through the hose 5, the female connector 4, and the male connector 31.

[0039] Continue to refer to Figure 1 and Figure 2 As shown, the anti-jet assembly 1 includes a baffle 11 and a flexible member 12. The baffle 11 is connected to the cabinet 2 and located between the server and the main pipeline assembly 3, thereby separating the server and the main pipeline assembly 3. The baffle 11 has multiple openings 110, each corresponding to a male connector 31. The flexible member 12 is a sheet-like structure, located on the side of the baffle 11 facing the male connector 31. The flexible member 12 has multiple through holes 120, each corresponding to an opening 110. The female connector 4 passes through the through holes 120 and the openings 110 and connects to the male connector 31.

[0040] In this embodiment, the flexible component 12 and the baffle 11 are connected by adhesive bonding to facilitate the disassembly and replacement of the flexible component 12. It is understood that in other embodiments, the flexible component 12 can also be connected to the baffle 11 in other ways, such as bolt connection or snap-fit ​​connection.

[0041] It should be noted that this embodiment does not specifically limit the material and shape of the flexible component 12. For example, the material of the flexible component 12 can be rubber or flexible ABS plastic, and the flexible component 12 can be replaced by a brush.

[0042] The anti-spray assembly 1 in this embodiment includes a baffle 11 and a flexible component 12. The baffle 11 is used to be disposed between the server and the main pipeline assembly 3 to separate the server from the main pipeline assembly 3, thereby reducing the possibility of liquid sprayed from the male connector 31 spraying onto the server inside the rack, thus effectively avoiding adverse effects on the server and ensuring the normal operation of the server. In addition, the flexible component 12 makes it less likely for installers to be scratched when plugging and unplugging connectors at the back of the rack, which facilitates operation and improves work efficiency.

[0043] Reference Figure 2 As shown, the baffle 11 includes a first plate portion 111 and a second plate portion 112. The first plate portion 111 is connected to the cabinet 2 and located between the server and the main pipeline assembly 3. The second plate portion 112 is connected to the end of the first plate portion 111 away from the cabinet 2 and is located on the side of the first plate portion 111 facing the main pipeline assembly 3, so that the first plate portion 111 and the second plate portion 112 form an L-shaped structure. The first plate portion 111, the second plate portion 112 and the cabinet 2 enclose and form a receiving groove 113. The main pipeline assembly 3 is disposed in the receiving groove 113. The first plate portion 111, the second plate portion 112 and the cabinet 2 together form a three-sided enclosure for the main pipeline assembly 3, which effectively ensures the reliability of the baffle 11 in preventing splashing, and leaves one side open to allow operators more room to move when plugging and unplugging quick connectors, which facilitates the operation of the operators. Multiple openings 110 are provided in the second plate portion 112 to make the first plate portion 111 located between the server and the main pipeline assembly 3 a closed structure, further enhancing the reliability of the anti-spray assembly 1.

[0044] In this embodiment, along the height direction, the shortest distance between the two male connectors 31 located at both ends of the main pipeline assembly 3 is a, and the length of the baffle 11 is b, where b ≥ a. Preferably, b > a, meaning that the baffle 11 can cover all the male connectors 31, thereby improving the reliability of the baffle 11 in preventing splashing and further reducing the situation where liquid sprayed from the male connectors 31 sprays onto the server in the rack, thus effectively ensuring the normal operation of the server. Moreover, there is no need to add a separate anti-splash box to each male connector 31, which greatly reduces the cost.

[0045] In this embodiment, the male connector 31 and the second plate portion 112 are provided with a preset distance along the width direction to reduce the situation where the liquid sprayed from the male connector 31 flows out from the opening 110 corresponding to the male connector 31, thereby further improving the splash prevention reliability of the anti-spray assembly 1.

[0046] It should be noted that this embodiment does not specifically limit the material of the baffle 11, as long as it can block liquid splashing. For example, the baffle 11 can be a sheet metal product.

[0047] Reference Figure 2 and Figure 3 As shown, Figure 3 for Figure 1 A magnified view of part B in the middle. Along the length direction, the edge of the second plate 112 away from the first plate 111 is recessed inward to form multiple openings 110. That is, the openings 110 are non-closed structures to facilitate the passage of the hose 5 at the tail of the female connector 4, which then bypasses the baffle 11 and connects to the heat dissipation device on the other side of the baffle 11.

[0048] In this embodiment, the opening 110 is arc-shaped to fit the profile of the pipe, so that when the hose 5 at the tail of the female connector 4 comes into contact with the inner wall of the opening 110, it can be subjected to uniform pressure, that is, arc surface to arc surface contact, thereby reducing the possibility of pipe damage. It is understood that in other embodiments, the opening 110 may also be other shapes, such as square or triangular.

[0049] Reference Figure 4 As shown, Figure 4 This is a partially enlarged frontal view of the anti-splash assembly provided in this application embodiment. Multiple slits 121 are spaced apart around each through hole 120, and these slits 121 communicate with the through holes 120 to ensure that the female connector 4 and the hose 5 can smoothly connect to the male connector 31 through the through holes 120. Simultaneously, without affecting the connection of the female connector 4 and part of the hose 5 through the through holes 120 to the male connector 31, this effectively reduces the possibility of liquid leakage from this location, thereby further improving the splash-proof reliability of the anti-splash assembly 1.

[0050] Reference Figure 3-Figure 5 As shown, Figure 5 This is a partially enlarged top view of the anti-jet assembly provided in this application embodiment. The anti-jet assembly 1 also includes a liquid collection box 13 and a connecting pipe 14. The liquid collection box 13 may be rectangular in structure. The liquid collection box 13 is connected to the first plate portion 111 and the second plate portion 112 respectively and is located at the bottom of the main pipeline assembly 3. It is used to collect liquid leaked from the male end connector 31 and the female end connector 4, and a drain port 130 is provided on the bottom wall of the liquid collection box 13. The connecting pipe 14 is located on the side of the liquid collection box 13 facing away from the main pipeline assembly 3. One end of the connecting pipe 14 is connected to the drain port 130, and the other end of the connecting pipe 14 is used to connect to a recovery device so that the leaked coolant can flow into the recovery device for recovery through the connecting pipe 14, thereby reducing environmental pollution and saving energy.

[0051] In this embodiment, in the height direction, the projection of each male connector 31 falls completely within the projection of the liquid collection box 13, so as to ensure that the liquid sprayed from the male connector 31 can flow into the liquid collection box 13, thereby ensuring the normal operation of the server in the rack.

[0052] In this embodiment, the liquid collection box 13 and the baffle 11 are integrally formed, which is convenient for manufacturing. It can be understood that in other embodiments, the liquid collection box 13 and the baffle 11 can also be detachably connected, such as bolted connection or snap-fit ​​connection.

[0053] It should be noted that the shape of the accumulator box 13 is not limited. It is only necessary that the projection of each male connector 31 falls completely within the projection of the accumulator box 13 in the height direction. For example, the accumulator box 13 has a funnel-shaped structure, and the drain port 130 is opened at the lowest point of the accumulator box 13 to ensure that the coolant can be discharged from the drain port 130.

[0054] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
