Description

Technical Field

[0001] This invention relates to the field of server technology, specifically to an integrated maintenance device for immersion liquid-cooled servers. Background Technology

[0002] Currently, data traffic is growing exponentially, especially with the development of applications such as cloud computing, AI, and supercomputing. Equipment power density is increasing daily, and the power density of single server racks in data centers is constantly rising. Traditional air cooling faces heat dissipation bottlenecks, and liquid cooling, which uses liquid cooling instead of air for heat exchange, is a good solution. Compared to air cooling technology, liquid cooling has higher heat dissipation efficiency and lower PUE, solving the problems of high heat density and high power consumption in servers, meeting the energy-saving and environmental protection requirements of data centers, and reducing the failure rate of data centers. Immersion liquid cooling systems use liquid as the cold source and insulating coolant as the refrigerant to immerse and cool servers.

[0003] However, maintaining liquid-cooled servers presents several challenges. Traditionally, the server is lifted from the liquid cooling system using hoisting equipment, the liquid is drained, and then the server is manually moved to a maintenance station for troubleshooting or disassembly. This approach has several drawbacks and potential risks: firstly, the hoisting equipment and maintenance station are separate, making the operation cumbersome and inconvenient; secondly, manual handling inevitably leads to bumps and damage to the server, potentially resulting in its destruction. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an integrated maintenance device for immersion liquid-cooled servers. This maintenance device enables the hoisting and transportation of servers, facilitating maintenance operations for liquid-cooled servers.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An integrated maintenance device for immersion liquid-cooled servers includes a main frame, one end of which is provided with a clearance for accommodating the liquid cooling system enclosure, and the other end of which is provided with a maintenance platform;

[0007] A gantry frame is slidably mounted on the main frame, and a hoisting device is mounted on the gantry frame;

[0008] The gantry has two working positions. When the gantry is in the first working position, the hoisting device is located above the liquid cooling system housing. When the gantry is in the second working position, the hoisting device is located above the maintenance platform.

[0009] Furthermore, the hoisting device includes a lifting beam, the two ends of which are connected to the upper end of the gantry frame via lifting components. The lifting components include lifting ropes and lifting carriages slidably connected to the gantry frame. A first roller is provided on the lifting carriage. The fixed end of the lifting rope is fixedly connected to the gantry frame, and the traction end of the lifting rope passes around the first roller and is fixedly connected to the lifting beam. The gantry frame is provided with a driving component for driving the two lifting carriages to move towards each other or away from each other. When the two lifting carriages move towards each other or away from each other, the lifting beam can be raised or lowered by the traction of the two lifting ropes.

[0010] Furthermore, the driving component includes lead screws located on both sides of the gantry frame, and the two ends of the lead screws are rotatably connected to the gantry frame through bearing assemblies. The two sides of the lifting carriage are respectively provided with nuts that cooperate with the lead screws. The gantry frame is provided with a drive motor for driving the two lead screws to rotate.

[0011] Furthermore, the drive motor is fixedly mounted on the crossbeam of the gantry frame, a drive pulley is mounted on the power output shaft of the drive motor, a driven pulley is mounted on the lead screw, and the drive pulley and the driven pulley are connected by a synchronous belt.

[0012] Furthermore, the synchronous belt forms a triangle under the action of the driving pulley and the two driven pulleys. A mounting bracket is provided between the two driven pulleys. A clamping wheel for pressing the synchronous belt is provided at the lower end of the mounting bracket. The upper end of the mounting bracket is connected to the crossbeam of the gantry frame through a screw and a locking nut.

[0013] Furthermore, both ends of the lifting beam are slidably connected to the gantry frame.

[0014] Furthermore, the lifting component also includes a second roller, and the traction end of the lifting rope passes through the first roller and the second roller in sequence and is fixedly connected to the lifting beam. Under the action of the second roller, the part of the lifting rope located between the second roller and the lifting beam is in a vertical state.

[0015] Furthermore, a boom is slidably mounted on the lifting beam, the boom being perpendicular to the lifting beam, and multiple lifting holes are provided on the boom along its length.

[0016] Furthermore, the inner end of the maintenance platform is rotatably connected to the main frame via a hinge shaft, and the outer end of the maintenance platform is connected to the gantry frame via a support rod.

[0017] When the gantry slides relative to the main frame, the gantry can drive the maintenance platform to swing up and down around the hinge axis via the support rod. When the gantry is in the second working position, the maintenance platform is in a horizontal state.

[0018] Furthermore, a baffle is provided on the main frame. When the gantry is in the second working position, the maintenance platform is in a horizontal state, and the weight of the maintenance platform can be transmitted to the gantry through the support rod, and push the gantry to press the gantry against the baffle.

[0019] The beneficial effects of this invention are:

[0020] This application provides an integrated maintenance device for immersion liquid-cooled servers, including a hoisting unit for lifting the server from the liquid cooling system and a maintenance platform for supporting disassembly, assembly, and maintenance. This maintenance device, used in conjunction with the tank of the immersion liquid-cooled server, covers usage scenarios such as server racking and delivery, racking and maintenance, and hanging for drying, achieving single-person operation and maintenance of immersion liquid-cooled servers and facilitating maintenance operations.

[0044] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0045] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0046] Example 1

[0047] like Figure 1 As shown, an integrated maintenance device for immersion liquid-cooled servers includes a main frame 1. The rear end of the main frame 1 has a clearance notch 13 for accommodating a liquid cooling system enclosure 6, and the front end of the main frame 1 has a maintenance platform 2 for supporting the server being maintained. A gantry frame 3 spans the main frame 1 and is slidably connected to it. A lifting device for hoisting the server is mounted on the gantry frame 3. The gantry frame 3 has two working positions: in the first working position, the lifting device is positioned above the liquid cooling system enclosure 6; in the second working position, the lifting device is positioned above the maintenance platform 2.

[0048] like Figure 5 As shown, the main frame 1 includes two parallel first uprights 11, with a second upright 12 positioned between the two first uprights 11. Both ends of the second upright 12 are fixedly connected to the first uprights 11. The first uprights 11 and the second upright 12 together form an "I"-shaped structure. The rear ends of the second upright 12 and the two first uprights 11 together form the clearance notch 13. A maintenance platform 2 is positioned between the two first uprights 11, in front of the second upright 12.

[0049] like Figure 1 and Figure 6 As shown, the gantry frame 3 includes a crossbeam 31 and columns 32 located at both ends of the crossbeam 31, the columns 32 extending vertically. The columns 32 are slidably connected to the main frame 1 via a first sliding assembly.

[0050] In one specific implementation, the first sliding component in this embodiment adopts a linear guide rail pair. The main frame 1 is located between the two columns 32 of the gantry 3. A first guide rail 14 extending in the front-rear direction is fixedly provided on the outer side of the first column 11 of the main frame 1 (with the side opposite to the two first columns 11 as the inner side). A first slider 321 that cooperates with the first guide rail 14 is fixedly provided on the inner side of the column 32 (with the side opposite to the two columns 32 as the inner side). For example, two first guide rails 14 extending in the front-rear direction are provided on the outer side of the first column 11, and the two first guide rails 14 are respectively located at the upper and lower ends of the outer side of the first column 11.

[0051] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the hoisting device includes a lifting beam 41 extending laterally, with both ends of the lifting beam 41 connected to the upper end of the gantry frame 3 via lifting components. The two lifting components have identical structures and are arranged symmetrically.

[0052] The lifting component includes a lifting rope 421 and a lifting slide 422 slidably connected to the crossbeam 31 of the gantry frame 3. The lifting slide 422 is capable of sliding left and right relative to the crossbeam 31. A first roller 424 is provided on the lifting slide 422. The lifting rope 421 includes a fixed end and a traction end. The fixed end of the lifting rope 421 is fixedly connected to the gantry frame 3, and the traction end of the lifting rope 421 passes around the first roller 424 and is fixedly connected to the lifting beam 41.

[0053] The gantry frame 3 is equipped with a drive component, which can drive the two lifting carriages 422 to move towards each other or away from each other. When the two lifting carriages 422 move towards each other or away from each other under the action of the drive component, the lifting beam 41 can be raised or lowered by the traction of the two lifting ropes 421.

[0054] In one specific implementation, in this embodiment, the fixed end of one lifting rope 421 is fixedly connected to the column 32 located on the left side, and the traction end of the lifting rope 421 passes around the first roller 424 located on the left lifting slide 422 and is fixedly connected to the left end of the lifting beam 41. The fixed end of the other lifting rope 421 is fixedly connected to the column 32 located on the right side, and the traction end of the lifting rope 421 passes around the first roller 424 located on the right lifting slide 422 and is fixedly connected to the right end of the lifting beam 41. Exemplarily, the portion of the lifting rope 421 located between the column 32 and the first roller 424 is in a horizontal state.

[0055] In one specific implementation, both lifting carriages 422 in this embodiment are slidably connected to the crossbeam 31 via a second sliding assembly, and the second sliding assembly is a linear guide rail pair. For example, a second guide rail 311 extending laterally is fixedly disposed on the lower side of the crossbeam 31, and a second slider 423 cooperating with the second guide rail 311 is fixedly disposed on the lifting carriage 422.

[0056] like Figure 3 , Figure 7 and Figure 8 As shown, the driving component includes lead screws 431 located on the front and rear sides of the gantry frame 3, and both ends of the lead screws 431 are rotatably connected to the gantry frame 3 via bearing assemblies. For example, both ends of the lead screws 431 are rotatably connected to the column 32 via bearing assemblies. Nuts 432 that mate with the lead screws 431 are respectively provided on the front and rear sides of the lifting carriage 422. The threads of the two nuts 432 mate with the same lead screw 431 have opposite directions, and correspondingly, the threads at both ends of the lead screw 431 also have opposite directions. Thus, when the lead screw 431 rotates, it can drive the two nuts 432 located on the same lead screw 431 to move towards each other or away from each other, thereby driving the two lifting carriages 422 to move towards each other or away from each other.

[0057] The drive component also includes a drive motor 433, whose power output shaft is connected to the two lead screws 431 respectively through a transmission mechanism. The drive motor 433 can drive the two lead screws 431 to rotate synchronously.

[0058] In one specific implementation, the drive motor 433 in this embodiment is detachably fixedly connected to the crossbeam 31 of the gantry frame 3. The transmission mechanism uses a synchronous belt 434 for transmission, including a drive pulley 4331 fixedly mounted on the power output shaft of the drive motor 433, and a driven pulley 4311 fixedly mounted on the right end of the lead screw 431. The drive pulley 4331 and the driven pulley 4311 are connected by the synchronous belt 434, and the synchronous belt 434 forms a triangle under the action of the drive pulley 4331 and the two driven pulleys 4311.

[0059] Furthermore, a mounting bracket 435 is provided between the two driven pulleys 4311. For example... Figure 12 As shown, the mounting bracket 435 includes a mounting plate 4351, with ear plates 4352 extending downwards perpendicular to the mounting plate 4351 at both ends. A portion of the synchronous belt 434, located between the two driven pulleys 4311, lies between the two ear plates 4352. A screw 4353 is fixedly welded to the upper side of the mounting plate 4351, with its upper end extending through the crossbeam 31 above it. A locking nut 436 is mounted on the screw 4353 above the crossbeam 31. A pressure roller 437 is positioned between the two ear plates 4352, outside the synchronous belt 434. Under the pressure of the locking nut 436, the pressure roller 437 presses the synchronous belt 434 upwards, thus tensioning the synchronous belt 434.

[0060] Furthermore, such as Figure 3 and Figure 12 As shown, guide blocks 4354 are respectively provided on the outer surface of the ear plates 4352 of the mounting bracket 435, and guide holes are provided on the guide blocks 4354 in a vertical direction. Guide posts 312 that cooperate with the guide holes are fixedly provided on the lower side of the crossbeam 31 of the gantry frame 3 by welding, and the guide posts 312 are inserted into the corresponding guide holes.

[0061] For example, the right end of the crossbeam 31 protrudes outside the right column 32 (with the side opposite to the two columns 32 as the inner side), and the driving pulley 4331, driven pulley 4311, synchronous belt 434 and pressure wheel 437 are all located outside the right column 32.

[0062] As one specific implementation method, such as Figure 7 and Figure 11As shown, the lifting carriage 422 in this embodiment includes a web 4221, with wing plates 4222 extending downward perpendicularly to the web 4221 at its front and rear ends. A second slider 423, cooperating with the second guide rail 311, is fixedly mounted on the upper side of the web 4221. Nuts 432, cooperating with the lead screw 431, are respectively provided on the outer sides of the two wing plates 4222. The first roller 424 is located inside the lifting carriage 422 (with the opposite side of the two lifting carriages 422 as the inner side). The first roller 424 includes a first wheel body and a first central shaft. The first wheel body is fixedly connected to the first central shaft, and both ends of the first central shaft are rotatably connected to the first connecting lugs 425 fixedly mounted on the wing plates 4222 via bearing assemblies. Exemplarily, the first wheel body and the first central shaft are an integral structure.

[0063] Furthermore, a third sliding component is provided between the lifting beam 41 and the column 32 to provide guidance for the up-and-down movement of the lifting beam 41.

[0064] In one specific implementation, the third sliding component in this embodiment adopts a linear guide rail pair. A third guide rail 322 extending vertically is fixedly installed on the inner side of the column 32 (with the side opposite to the two columns 32 as the inner side). End plates 411 are fixedly installed at both ends of the lifting beam 41 by welding, and a third slider 412 that cooperates with the third guide rail 322 is fixedly installed on the end plate 411.

[0065] Furthermore, such as Figure 10 As shown, the upper end of the end plate 411 is fixedly provided with a hanging ear 4111 extending inward perpendicularly to the end plate 411 (with the opposite side of the two end plates 411 as the inner side) by welding, and the traction end of the lifting rope 421 is fixedly connected to the hanging ear 4111.

[0066] Furthermore, such as Figure 6 and Figure 10 As shown, the lifting component also includes a second roller 426 disposed on the column 32, and the second roller 426 is located between the lifting carriage 422 and the lifting beam 41. The traction end of the lifting rope 421 passes through the first roller 424 and the second roller 426 in sequence and is fixedly connected to the lifting beam 41. Under the action of the second roller 426, the part of the lifting rope 421 located between the second roller 426 and the lifting beam 41 is in a vertical state.

[0067] In one specific embodiment, the second roller 426 in this example includes a second wheel body and a second central shaft. The second wheel body is fixedly connected to the second central shaft, and both ends of the second central shaft are rotatably connected to second connecting ears 427 fixedly mounted on the column 32 via bearing assemblies. Exemplarily, the second wheel body and the second central shaft are an integral structure.

[0068] Furthermore, such as Figure 1 and Figure 6 As shown, the lifting beam 41 is provided with a lifting arm 44 that can slide laterally relative to the lifting beam 41, and the lifting arm 44 is provided with a plurality of lifting holes 4421 evenly arranged along the front-back direction.

[0069] As one specific implementation method, such as Figure 2 and Figure 13 As shown, the boom 44 in this embodiment includes a horizontal plate 441 extending in the front-to-back direction. A vertical plate 442 extending in the front-to-back direction is provided on the lower side of the horizontal plate 441. The horizontal plate 441 and the vertical plate 442 together form a T-shaped structure. The lifting hole 4421 is provided on the vertical plate 442. On the upper side of the horizontal plate 441, on the front and rear sides of the lifting beam 41, there are upright plates 443 respectively. A stiffening plate 444 is provided between the outer side of the upright plate 443 (with the side opposite to the two upright plates 443 as the inner side) and the horizontal plate 441. A fourth guide rail 413 extending in the transverse direction is provided on both the front and rear sides of the lifting beam 41. A fourth slider 4431 that cooperates with the fourth guide rail 413 is fixedly provided on the inner side of the upright plate 443 (with the side opposite to the two upright plates 443 as the inner side).

[0070] Furthermore, such as Figure 14 and Figure 15 As shown, the inner end of the maintenance platform 2 (with the end closest to the second upright 12 as the inner end) is rotatably connected to the main frame 1. The left and right ends of the maintenance platform 2 are respectively provided with hinge shafts, and the inner surface of the first upright 11 is respectively provided with hinge holes that mate with the hinge shafts. The maintenance platform 2 as a whole can swing up and down around the hinge shafts.

[0071] The outer ends of the maintenance platform 2 (with the end closest to the second upright 12 as the inner side) are respectively connected to the gantry frame 3 via support rods 5. One end of the support rod 5 is hinged to the maintenance platform 2, and the other end of the support rod 5 is hinged to the hinge lug 323 fixedly installed on the upright 32 of the gantry frame 3.

[0072] When the gantry 3 slides back and forth along the main frame 1, the gantry 3 can drive the maintenance platform 2 to swing up and down around the hinge axis via the support rod 5, and asFigure 16 As shown, when the gantry 3 is in the first working position, the maintenance platform 2 is in a vertical state; Figure 1 As shown, when the gantry 3 is in the second working position, the maintenance platform 2 is in a horizontal state.

[0073] In one specific embodiment, the support rod 5 in this embodiment includes a first connecting part 51 hinged to the column 32 and a second connecting part 52 hinged to the maintenance platform 2. Since the maintenance platform 2 is located between the two first uprights 11, i.e., inside the first uprights 11, while the column 32 is located outside the first uprights 11, the first connecting part 51 and the second connecting part 52 are not on the same vertical plane. Therefore, a third connecting part 53 is provided between the first connecting part 51 and the second connecting part 52 to connect them together. The first uprights 11 are provided with a clearance space to avoid the third connecting part 53. That is, when the maintenance platform 2 swings up and down around the hinge axis, the third connecting part 53 can move within the clearance space without interfering with the first uprights 11.

[0074] For example, the first upright frame 11 includes two longitudinal beams 111 extending in the longitudinal direction, and multiple vertical beams 112 extending in the vertical direction are arranged between the two longitudinal beams 111 in the front-back direction. The upper and lower ends of the vertical beams 112 are fixedly connected to the longitudinal beams 111 by welding. The square area formed by the two longitudinal beams 111 and the two vertical beams 112 at the front end is the clearance space.

[0075] Furthermore, such as Figure 1 and Figure 4 As shown, a baffle 15 is fixedly provided at the front end of the outer side of the first upright 11 to prevent the gantry 3 from sliding forward further. The baffle 15 determines the second working position of the gantry 3, that is, when the column 32 of the gantry 3 abuts against the baffle 15, the gantry 3 is in the second working position. When the column 32 of the gantry 3 abuts against the baffle 15, the support rod 5 is tilted backward, that is, the weight of the maintenance platform 2 is transmitted to the gantry 3 through the support rod 5, and pushes the gantry 3 forward to press it against the baffle 15.

[0076] In this way, the baffle 15 not only determines the second working position of the gantry 3, but also enables the maintenance platform 2 to maintain a stable horizontal state, thus supporting the maintenance platform 2.

[0077] like Figure 16 and Figure 17As shown, when the maintenance platform 2 is in a vertical position, the third connecting part 53 of the support plate presses against the rear side wall of the clearance space, that is, against the front side of the second vertical beam 112 from the front. Thus, during operation, under the weight of the maintenance platform 2 itself, it can be stably maintained in a vertical position, thereby ensuring that the gantry 3 can be stably maintained in the first working position, preventing the gantry 3 from moving forward or backward during server hoisting.

[0078] Furthermore, a buffer pad made of rubber material is fixedly provided on the baffle 15.

[0079] Furthermore, such as Figure 4 and Figure 5 As shown, casters 16 are respectively provided at the front and rear ends of the lower side of the first upright 11 of the main frame 1. For example, the casters 16 are casters 16 with braking function.

[0080] When server maintenance is required, the specific operation process is as follows:

[0081] First, move the maintenance equipment to the position of the liquid cooling system housing 6, and position the liquid cooling system housing 6 within the clearance notch 13 of the main frame 1, i.e. Figure 1 The state shown.

[0082] Second, if the gantry 3 is currently in the second working position, it is pushed backward until it moves to the first working position. During this process, the maintenance platform 2 will swing along with the gantry 3 and eventually reach a vertical position.

[0083] If the gantry 3 is in the first working position at this time, then this step is ignored and the third step is performed directly.

[0084] Third, start the drive motor 433. At this time, the lifting beam 41 will move downward under its own weight until it reaches the appropriate position, at which point the drive motor 433 will stop. Then, connect both ends of the server to be maintained to the boom 44 via slings.

[0085] Since the maintenance platform 2 is in a vertically suspended state at this time, the operator will not be obstructed by the maintenance platform 2 and can easily connect the server to the crane arm 44.

[0086] Fourth, the drive motor 433 actuates, causing the lifting beam 41 to move upward, thereby lifting the server to be maintained. Once the server is completely removed from the coolant surface of the liquid cooling system, the drive motor 433 stops. At this point, the server is suspended in mid-air for drying.

[0087] Fifth, after the coolant has drained from the server to be maintained, pull the gantry 3 backward until it rests against the baffle 15. During this process, the maintenance platform 2 will swing under the pushing action of the gantry 3. Specifically, it will swing upward first, and after reaching its highest point, it will swing downward until the maintenance platform 2 is in a horizontal state.

[0088] Sixth, the drive motor 433 is activated, and the lifting beam 41 moves downward under its own weight, thereby placing the server to be maintained onto the maintenance platform 2 for further inspection.

[0089] Example 2

[0090] One lifting rope 421 has its fixed end fixedly connected to the column 32 on the left side. The traction end of this lifting rope 421 passes over the first roller 424 on the lifting carriage 422 on the right side and is then fixedly connected to the left end of the lifting beam 41. Another lifting rope 421 has its fixed end fixedly connected to the column 32 on the right side. The traction end of this lifting rope 421 passes over the first roller 424 on the lifting carriage 422 on the left side and is then fixedly connected to the right end of the lifting beam 41. The remaining structure is the same as in Embodiment 1.

[0091] Example 3

[0092] The fixed end of the lifting rope 421 is fixedly connected to the middle of the crossbeam 31, and the traction end of the lifting rope 421 is fixedly connected to the middle of the lifting beam 41. Both lifting carriages 422 are located between the two lifting ropes 421, and the first roller 424 is located on the outer side of the lifting carriages 422 (with the opposite side of the two lifting carriages 422 as the inner side). When the two lifting carriages 422 move in opposite directions under the action of the driving component, they will spread apart the two lifting ropes 421, thereby driving the lifting beam 41 to move upwards.

[0093] Furthermore, the second roller 426 is disposed on the lifting beam 41. During the process of the lifting carriage 422 moving in opposite directions under the action of the driving component to spread the two lifting ropes 421 apart, the second roller 426 can ensure that the part of the lifting rope 421 between the lifting beam 41 and the second roller 426 is in a vertical state.

[0094] The rest of the structure is the same as in Example 1.
