Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling servers, in particular to an operation and maintenance device for a liquid cooling server. Background Art

[0002] Immersion liquid cooling technology is a heat dissipation method that uses liquid as a medium to absorb and transfer the heat generated by the heating element. Compared with traditional heat dissipation methods (air cooling and water cooling), immersion liquid cooling has higher heat dissipation efficiency and lower noise. Among them, the single-phase immersion liquid cooling system is widely used because the immersion liquid cooling cabinet design is simpler, the fluorinated liquid used for cooling is easier to operate and maintain, and there are fewer hidden dangers in material compatibility and pollutants in the cycle. The single-phase immersion liquid cooling system mainly consists of three parts: an outdoor cold source, an immersion liquid cooling cabinet (used to store liquid-cooled servers), and a CDU (Coolant Distribution Unit). When actually deployed in a data center, the volume of the immersion liquid cooling cabinet can usually accommodate dozens of liquid-cooled servers. In the traditional air cooling system, when the server is abnormal, the operation and maintenance personnel quickly locate the abnormal server according to the color status of the status indicator set on the BMC (Baseboard Management Controller). However, in the immersion liquid cooling system, since the liquid-cooled server is immersed in liquid and enclosed inside the immersion liquid cooling cabinet, the operation and maintenance personnel cannot directly determine the location of the abnormal server through the status indicator. This requires manually taking the liquid-cooled servers out of the liquid one by one, and then observing and locating them, which increases the difficulty and complexity of operation and maintenance.

[0025] See also Figure 1-Figure 3 ,like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a liquid-cooled server 300 operation and maintenance device 10, including a liquid-cooled cabinet 100, a lifting drive assembly 200, a liquid-cooled server 300 and a limit switch 400; the lifting drive assembly 200 and the liquid-cooled server 300 are movably arranged inside the liquid-cooled cabinet 100; the limit switch 400 is arranged inside the liquid-cooled cabinet 100 and is located above the lifting drive assembly 200 and the liquid-cooled server 300, and there is a distance between the limit switch 400 and the lifting drive assembly 200 and the liquid-cooled server 300, and the limit switch 400 is electrically connected to the lifting drive assembly 200; the liquid-cooled server 300 is connected to one end of the lifting drive assembly 200; when the liquid-cooled server 300 fails, the lifting drive assembly 200 drives the liquid-cooled server 300 to lift and move until the lifting drive assembly 200 and / or the liquid-cooled server 300 abuts against the limit switch 400 and stops driving the liquid-cooled server 300 to lift and move.

[0026] In the present embodiment, the liquid cooling cabinet 100 is a hollow cavity structure with a certain internal volume, and the interior of the liquid cooling cabinet 100 is filled with liquid coolant, such as fluorinated liquid. The lifting drive assembly 200 is installed inside the liquid cooling cabinet 100, and at the same time, the liquid cooling server 300 is also arranged inside the liquid cooling cabinet 100 and immersed in the liquid coolant to be cooled by the liquid coolant. The number of lifting drive assemblies 200 and liquid cooling servers 300 can be set to one or more, and each liquid cooling server 300 is connected to at least one lifting drive assembly 200. One end of the lifting drive assembly 200 is fixedly connected to the inner wall of the liquid cooling cabinet 100, and the end can be connected to the inner side wall or the inner bottom surface of the liquid cooling cabinet 100, so as to fix the lifting drive assembly 200. The other end of the lifting drive assembly 200 is a movable end, and the movable end of the lifting drive assembly 200 is connected to the liquid cooling server 300, and the liquid cooling server 300 can be configured to be detachably connected to the lifting drive assembly 200 or fixedly connected to the lifting drive assembly 200. The end of the lifting drive assembly 200 connected to the liquid cooling server 300 can perform autonomous telescopic movement, thereby being able to drive the liquid cooling server 300 to perform vertical lifting or lowering movement.

[0027] The limit switch 400 is fixedly disposed inside the liquid cooling cabinet 100 and is located above each liquid cooling server 300 and each lifting drive assembly 200. Specifically, Figure 2As shown in (a), each set of connected lifting drive components 200 and liquid cooling servers 300 has a limit switch 400 located above itself. The limit switch 400 can be set to face the liquid cooling server 300, or to face the lifting drive component 200, or to face the liquid cooling server 300, that is, the lifting drive component 200. Then, when the lifting drive component 200 drives the liquid cooling server 300 to lift, as shown in FIG. Figure 2 As shown in (b), after being lifted to a certain height, one or both of the lifting drive assembly 200 and the liquid cooling server 300 will abut against the limit switch 400. Since there is an electrical connection between the limit switch 400 and the lifting drive assembly 200, when one or both of the lifting drive assembly 200 and the liquid cooling server 300 in a group of lifting drive assemblies 200 and liquid cooling servers 300 abut against the corresponding limit switch 400, the lifting drive assembly 200 will receive a disconnection signal from the limit switch 400 and stop driving the liquid cooling server 300 to continue lifting, so as to prevent the lifting drive assembly 200 from driving the liquid cooling server 300 to lift too high a height, thereby preventing the liquid cooling server 300 from being damaged by collision.

[0028] In the specific operation and maintenance process, the operation and maintenance device 10 of the liquid-cooled server 300 is also connected to a CDU module, in which a main control unit is encapsulated. The main control unit is electrically connected to each lifting drive assembly 200 inside the liquid-cooled cabinet 100. At the same time, each liquid-cooled server 300 is also electrically connected to a BMC module located inside the liquid-cooled cabinet 100. The BMC module can sense the abnormality of the liquid-cooled server 300 in real time and determine the identification information of the specific liquid-cooled server 300 that has the abnormality. Subsequently, the BMC module will send the identification information of the liquid-cooled server 300 that has the abnormality to the main control unit in the CDU module. After the main control unit obtains the identification information of the liquid-cooled server 300 that has the abnormality, it will display a prompt message of the current abnormality on a display module with a display function. When the operation and maintenance personnel learn through the prompt message that there is an abnormal liquid-cooled server 300 at this time, they can send an operation and maintenance instruction to the main control unit through the display module. In response to the operation and maintenance instruction, the main control unit can send a driving instruction to the lifting drive assembly 200 corresponding to the abnormal liquid-cooled server 300, so that the lifting drive assembly 200 starts to drive the abnormal liquid-cooled server 300 to lift. After lifting a certain distance, the limit switch 400 stops the lifting drive assembly 200, and then the top of the abnormal liquid-cooled server 300 will have a higher height than the top of other normal liquid-cooled servers 300, and the operation and maintenance personnel can quickly determine the position of the abnormal liquid-cooled server 300 by visual inspection. Even if there is only a single abnormal liquid-cooled server 300 in the liquid-cooled cabinet 100, the operation and maintenance personnel can quickly take out the liquid-cooled server 300. Furthermore, the operation and maintenance personnel can quickly perform operation and maintenance operations on the abnormal liquid-cooled server 300, which greatly improves the operation and maintenance efficiency of the liquid-cooled server 300.

[0029] In one embodiment, if Figure 2 As shown, the lifting drive assembly 200 includes a cylinder body 210, a push rod 220 and a fixed bracket 230; the fixed bracket 230 is fixedly connected to the inner side wall of the liquid cooling cabinet 100; the bottom end of the cylinder body 210 is fixedly connected to the fixed bracket 230; the cylinder body 210 is sleeved on the outside of the push rod 220; the push rod 220 can be lifted along the axial direction of the cylinder body 210 and protrude from the top end of the cylinder body 210; the top end of the push rod 220 is connected to the liquid cooling server 300.

[0030] In this embodiment, the cylinder 210 is a hollow tubular structure, and the push rod 220 can be integrally embedded in the hollow structure of the cylinder 210. The fixed bracket 230 is a support structure fixedly connected to the inner side wall of the liquid cooling cabinet 100, which can be set as a support structure with a certain length, so that the cylinders 210 in each lifting drive assembly 200 are connected to the fixed bracket 230. The bottom end of the cylinder 210 is fixedly connected to the fixed bracket 230, and the top end of the cylinder 210 is movably mounted with the push rod 220. The cylinder 210 and the push rod 220 can be screwed to implement transmission. When the cylinder 210 is powered on, the push rod 220 can be driven to perform a spiral lifting motion, thereby causing the push rod 220 to protrude a certain distance from the cylinder 210. At this time, since the top end of the push rod 220 is connected to the liquid cooling server 300, when the push rod 220 is driven by the cylinder 210 to perform a lifting motion, the liquid cooling server 300 can be driven by the push rod 220 to perform a lifting motion. Among them, the cylinder body 210 can also be set as a cylinder body 210, and the compressed gas is used to drive the push rod 220 to lift or lower; or, the cylinder body 210 can be set as a structure with a linear stepper motor inside, and then the motor drives the push rod 220 to lift or lower.

[0031] In one embodiment, if Figure 3 As shown, a plurality of positioning holes 231 arranged in parallel are formed on the fixing bracket 230 ; a mounting hole 211 matching with the positioning hole 231 is provided at the bottom end of the cylinder body 210 .

[0032] In this embodiment, a plurality of parallel positioning holes 231 may be arranged axially on the fixing bracket 230, and each positioning hole 231 has a certain spacing. When the lifting drive assembly 200 needs to be installed on the fixing bracket 230, the mounting hole 211 provided at the bottom end of the cylinder body 210 may be overlapped with the positioning hole 231, and then a bolt may be screwed in from the bottom end of the positioning hole 231, so that the bolt passes through the positioning hole 231 and the mounting hole 211 in sequence, thereby fixing the cylinder body 210 to the top of the fixing bracket 230. By matching the mounting hole 211 with the positioning hole 231, the lifting drive assembly 200 may be detachable, and different spacings between the lifting drive assemblies 200 may be set by connecting the cylinder body 210 to different positioning holes 231 as needed.

[0033] In one embodiment, if Figure 2 As shown, the liquid-cooled server 300 includes a server body 310 and a server mounting ear 320; one end of the server mounting ear 320 is fixedly connected to the server body 310 and protrudes from one side of the server body 310; the other end of the server mounting ear 320 is detachably connected to the top of the lifting drive assembly 200.

[0034] In this embodiment, the server body 310 is the main structure for realizing the functions of the server itself, and the server mounting ear 320 is a connection structure fixedly connected to the side wall of the server body 310. The server mounting ear 320 protrudes from the side wall of the server body 310. When the liquid-cooled server 300 needs to be placed in the liquid-cooled cabinet 100, the server mounting ear 320 can be aligned with the top of the lifting drive assembly 200, and then the server mounting ear 320 can be detachably installed on the lifting drive assembly 200 by bolt fixing or the like. Alternatively, a matching clamping structure can also be provided on the server mounting ear 320 and the lifting drive assembly 200 to improve the efficiency of installation and removal of the liquid-cooled server 300. The liquid-cooled server 300 is connected to the lifting drive assembly 200 through the server hanging ear 320. There is a certain distance between the bottom end of each liquid-cooled server 300 and the inner bottom surface of the liquid-cooled cabinet 100. Therefore, the liquid-cooled server 300 is actually hung inside the liquid-cooled cabinet 100, which can ensure that the server body 310 is in contact with other structures only through the server hanging ear 320, thereby ensuring the stable operation of the liquid-cooled server 300.

[0035] In one embodiment, if Figure 1 and Figure 2 As shown, the liquid-cooled server 300 operation and maintenance device 10 also includes a server bracket 500; the server bracket 500 is fixedly connected to the inner side wall of the liquid-cooled cabinet 100; when the liquid-cooled server 300 is not lifted by the lifting drive assembly 200, the bottom end of the server mounting ear 320 abuts against the top end of the server bracket 500.

[0036] In this embodiment, the server bracket 500 is disposed inside the liquid cooling cabinet 100 and protrudes from the side wall of the liquid cooling cabinet 100. Figure 2 As shown in (a), when the liquid-cooled server 300 is not lifted by the lifting drive assembly 200, the bottom end of the server hanging ear 320 abuts against the top of the server bracket 500, and then the liquid-cooled server 300 is supported by the server bracket 500 as a whole. Specifically, after the server hanging ear 320 is hung on the top of the lifting drive assembly 200, its edge will also protrude from the top of the lifting drive assembly 200, and the protruding edge can just be supported by the server bracket 500. By setting up the server bracket 500, the overall weight of the liquid-cooled server 300 can be supported by the server bracket 500, preventing the lifting drive assembly 200 from being damaged by the pressure of the liquid-cooled server 300 for a long time.

[0037] In one embodiment, if Figure 2As shown, the liquid-cooled server 300 operation and maintenance device 10 also includes a pressure-sensitive sensor 600; the pressure-sensitive sensor 600 is arranged below the server hanging ear 320; when the lifting drive assembly 200 is connected to the server hanging ear 320 and the lifting drive assembly 200 does not perform a lifting movement, the server hanging ear 320 abuts against the pressure-sensitive sensor 600, and the pressure-sensitive sensor 600 senses the weight of the server body 310.

[0038] In this embodiment, the pressure-sensitive sensor 600 is disposed inside the liquid cooling cabinet 100. Figure 2 As shown in (a), when a liquid-cooled server 300 is mounted on the lifting drive assembly 200, and the lifting drive assembly 200 does not drive the liquid-cooled server 300 to perform lifting movement, the server mounting ear 320 will abut against the pressure-sensitive sensor 600, and then the pressure-sensitive sensor 600 can sense the pressure caused by the weight of the liquid-cooled server 300 itself, and transmit the sensing result to the main control unit electrically connected to the pressure-sensitive sensor 600. When operation and maintenance is required, the main control unit can know whether the lifting drive assembly 200 corresponding to the pressure-sensitive sensor 600 is mounted with a liquid-cooled server 300 based on the sensing result of the pressure-sensitive sensor 600, and display the corresponding prompt information on the display module. Among them, a single pressure-sensitive sensor 600 corresponds to a single lifting drive assembly 200 and its corresponding liquid-cooled server 300.

[0039] In one embodiment, if Figure 2 As shown, the liquid cooling cabinet 100 includes a cabinet body 110 and a cabinet cover 120 ; the cabinet cover 120 is rotatably connected to the cabinet body 110 and covers the top of the cabinet body 110 .

[0040] In this embodiment, the cabinet body 110 in the liquid cooling cabinet 100 is a structure with a cavity for accommodating the liquid cooling server 300. A cabinet cover 120 that can be opened and closed is provided on the top of the cabinet body 110. Furthermore, during daily operation, the liquid cooling cover can cover the liquid cooling server 300 located inside the liquid cooling cabinet 100. When operation and maintenance are required, the operation and maintenance personnel will open the liquid cooling cover to ensure the stable operation of each liquid cooling server 300.

[0041] In one embodiment, if Figure 1 As shown, a caster 130 is disposed at the bottom end of the liquid cooling cabinet 100 ; the caster 130 is rotatably connected to the bottom end of the liquid cooling cabinet 100 .

[0042] In this embodiment, the casters 130 are rotatably connected to the bottom end of the liquid cooling cabinet 100 . When the liquid cooling cabinet 100 needs to be moved as a whole, the casters 130 make the liquid cooling cabinet 100 easy to move.

[0043] In one embodiment, if Figure 1 As shown, the number of lifting drive components 200, the number of liquid cooling servers 300 and the number of limit switches 400 are all multiple; a single lifting drive component 200 is connected to a single liquid cooling server 300; a single limit switch 400 is arranged above a single liquid cooling server 300 and the corresponding lifting drive component 200; and each liquid cooling server 300 is arranged in parallel.

[0044] In this embodiment, a plurality of lifting drive assemblies 200, a plurality of liquid cooling servers 300, and a plurality of limit switches 400 are arranged inside the liquid cooling cabinet 100. The plurality of lifting drive assemblies 200, the plurality of liquid cooling servers 300, and the plurality of limit switches 400 can be divided into a plurality of separate groups. Each group includes a single liquid cooling server 300 and at least one lifting drive assembly 200 connected to the single liquid cooling server 300, and at least one limit switch 400 directly opposite to the single liquid cooling server 300 or the lifting drive assembly 200. Between each group, each liquid cooling server 300 is arranged in parallel, which can ensure that each liquid cooling server 300 inside the liquid cooling cabinet 100 is arranged in an orderly manner, and ensure the stable operation of the liquid cooling server 300.

[0045] In one embodiment, if Figure 1 and Figure 2 As shown, the lifting drive assembly 200 is symmetrically arranged on both sides of the liquid cooling server 300 .

[0046] In this embodiment, each liquid-cooled server 300 is connected to two lifting drive assemblies 200 , and the lifting drive assemblies 200 are symmetrically arranged on both sides of a single liquid-cooled server 300 to achieve uniform lifting of the liquid-cooled server 300 .

[0047] Based on the above structure and its connection method, the liquid-cooled server operation and maintenance device provided by the embodiment of the utility model sets a lifting drive component inside the liquid-cooled cabinet. When it is necessary to operate and maintain the abnormal liquid-cooled server, the lifting drive component can lift the abnormal liquid-cooled server, and after lifting to a certain height, the limit switch can limit the lifting drive component from continuing to lift the liquid-cooled server, thereby making the top of the abnormal liquid-cooled server protrude higher than other liquid-cooled servers. Based on this, the operation and maintenance personnel can quickly locate the abnormal liquid-cooled server and perform operation and maintenance, thereby eliminating the steps of taking out the liquid-cooled servers one by one for inspection, reducing the complexity of the operation, and improving the operation and maintenance efficiency.

[0048] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
