Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled chassis technology, and more specifically, to a liquid-cooled chassis. Background Technology

[0002] Currently, for large server data centers, some technology companies have begun exploring more environmentally friendly and energy-efficient cooling methods in recent years, leading to the development of liquid cooling technology. This technology uses a specially customized liquid to completely immerse the server and achieves efficient cooling through precise liquid temperature control, significantly reducing energy consumption while improving temperature control accuracy. This method also eliminates the need for internal cooling fans, relying solely on liquid circulation to remove heat, greatly reducing system noise and improving operational comfort.

[0003] However, current immersion liquid-cooled data center chassis technology still primarily relies on manual labor or external tools to remove the motherboard or other components from the liquid for repair when facing server motherboard or other component failures. This maintenance method is not only inefficient but may also introduce additional risks during operation, such as liquid leakage or damage to server equipment. Furthermore, the maintenance requirements of traditional immersion liquid-cooled chassis limit the equipment installation layout, supporting only horizontal placement of equipment. This not only challenges the space utilization of the data center but also limits the power density of servers, thus affecting overall computing performance and energy efficiency.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To address the problem of low server maintenance efficiency caused by the need for manual or external tools to remove the motherboard or other components from the liquid when they malfunction in a liquid-cooled chassis, this invention provides a liquid-cooled chassis.

[0036] Please refer to Figures 1 to 8As shown, the present invention provides a liquid-cooled chassis, including a chassis body 1, a lifting device 2, and a server 3. The chassis body 1 has a receiving cavity for accommodating the server 3. The lifting device 2 is disposed at the bottom of the receiving cavity and includes a driving component 20 and a vertically movable lifting platform 21. The output end of the driving component 20 is connected to the lifting platform 21. The server 3 is disposed on the lifting platform 21 and has a control switch 30 connected to the driving component 20. The control switch 30 has an open position and a closed position. When the control switch 30 is in the closed position, the output end of the driving component 20 is fixed. When the control switch 30 is in the open position, the output end of the driving component 20 is movably disposed to drive the lifting platform 21 to perform lifting and lowering movements.

[0037] The control switch 30 on server 3 is connected to the drive component 20 of the lifting device 2, allowing maintenance personnel to control the raising and lowering of server 3 simply by operating the control switch 30 without additional tools. This design greatly simplifies the hardware maintenance process, especially in immersion liquid cooling environments, eliminating the need for manual removal of server 3 from the coolant, avoiding potential liquid leakage and contamination risks, and reducing maintenance time and labor costs. Furthermore, it solves the technical problem of low maintenance efficiency in existing technologies where manual or external tools are required to remove the motherboard or other components from the liquid when they malfunction in a liquid-cooled server 3 chassis.

[0038] Furthermore, the on / off state of the control switch 30 ensures that the output of the drive component 20 can be fixed or released at the appropriate time, avoiding the risk of accidental movement of the server 3 without human control, thereby improving the safety of maintenance operations. This precise control also prevents collisions and damage to other hardware during the lifting and lowering of the server 3. Simultaneously, the automated lifting device 2 allows the server 3 to be quickly raised when maintenance is required, without needing to reserve a fixed height of upper space for manual operation, significantly improving the space utilization within the chassis. When maintenance is not required, the server 3 can be lowered to its lowest position to maximize the use of the volume within the housing, thereby increasing the power density of the data center.

[0039] like Figure 4As shown, the lifting device 2 also includes a base 22 and a movable component 23. The movable component 23 is movably connected to the base 22 and the lifting platform 21, respectively. The movable component 23 has a retracted state where it is stored between the lifting platform 21 and the base 22, and an extended state where the lifting platform 21 moves relative to the base 22. The driving component 20 is disposed on the base 22 and its output end is connected to the movable component 23 to drive the movable component 23 to move between the retracted state and the extended state.

[0040] The design of the movable component 23 allows it to switch between a retracted and extended state based on changes in the output of the drive component 20, enabling the server 3 to be quickly adjusted to the ideal maintenance height in a short time without the need for manual relocation. This instant response capability and precise positioning function greatly facilitates hardware inspection and repair, reducing maintenance time. Furthermore, when not in use, the movable component 23 can be stored between the lifting platform 21 and the base 22 without occupying extra space, thus ensuring that the server 3 can fit snugly inside the chassis 1 in the non-maintenance state, maximizing the utilization of the housing volume and improving the density and efficiency of server 3 deployment.

[0041] Meanwhile, the design of the movable component 23 makes it easy to adjust or replace according to different server 3 weights and sizes, enhancing the flexibility of the lifting device 2 and its adaptability to different application scenarios. Furthermore, this modular design facilitates later maintenance and upgrades, eliminating the need to replace the entire lifting device 2 and reducing upgrade costs.

[0042] Compared to traditional rigid connections, the movable connection between the movable component 23 and the base 22 and the lifting platform 21 reduces friction and impact during lifting, slows down the wear rate of mechanical parts, extends the service life of the lifting device 2, and also reduces the frequency of system maintenance and lowers operating costs.

[0043] In this embodiment, there are two movable components 23, which are arranged opposite to each other on the base 22 and are respectively connected to the lifting platform 21.

[0044] In this embodiment, the movable component 23 includes a first movable frame 24 and a second movable frame 25. The top of the first movable frame 24 is provided with a first sliding rod 240, which is slidably connected to the lifting platform 21. The bottom of the first movable frame 24 is provided with a first fixed rod, which is rotatably connected to the base 22. The top of the second movable frame 25 is provided with a second fixed rod, which is rotatably connected to the lifting platform 21. The bottom of the second movable frame 25 is provided with a second sliding rod 250, which is slidably connected to the base 22. The first movable frame 24 and the second movable frame 25 are rotatably connected.

[0045] The top of the first movable frame 24 is slidably connected to the lifting platform 21 via a first sliding rod 240, while the bottom is rotatably connected to the base 22 via a first fixed rod. Similarly, the top of the second movable frame 25 is rotatably connected to the lifting platform 21 via a second fixed rod, while the bottom is slidably connected to the base 22 via a second sliding rod 250. This design ensures smoothness and stability during lifting and lowering, preventing potential jamming or shaking during server 3's lifting and lowering, thus improving user experience and the operational safety of server 3.

[0046] The rotatable connection between the first movable frame 24 and the second movable frame 25 allows the entire movable component 23 to occupy a small space when the lifting device is fully folded. When the server 3 is not being lifted and is in a retracted state, the movable component 23 can be stored inside the chassis, reducing the space occupied by the rack and facilitating the optimized layout of the data center's internal space.

[0047] In this embodiment, the lifting platform 21 includes a support plate 210 and folding plates 211 located on both sides of the support plate 210. Each folding plate 211 has a first sliding hole 212. The base 22 includes a main base plate 220 and two mounting plates 221 oppositely disposed on the main base plate 220. Each mounting plate 221 has a first mounting hole. The first movable frame 24 further includes two oppositely disposed first mounting rods 241. The two ends of the first sliding rod 240 are slidably inserted into corresponding first sliding holes 212, and the top ends of the two first mounting rods 241 are respectively connected to the portions of the first sliding rods 240 extending out of the first sliding holes 212. The two ends of the first fixed rod are rotatably inserted into corresponding first mounting holes, and the top ends of the two first mounting rods 241 are respectively connected to the portions of the first fixed rod extending out of the first mounting holes. The first sliding hole 212 is a strip-shaped hole.

[0048] The first sliding hole 212 on the folding plate 211, combined with the first mounting hole on the mounting plate 221, provides a precise guide path for the first mounting rod 241 and the first fixed rod. This guide design allows the movable component 23 to move smoothly along a predetermined trajectory when switching between the extended and retracted states, which not only improves the smoothness of the lifting and lowering of the server 3, but also helps to reduce noise and vibration during the movement.

[0049] Furthermore, an adaptive torque balance system is formed through the sliding connection between the first sliding rod 240 and the folding plate 211, and the rotational connection between the first fixed rod and the main base plate 220. This means that during the lifting process, regardless of changes in the weight of the server 3, the first movable frame 24 and the second movable frame 25 can automatically adjust their stress state to ensure that the server 3 remains stable, improving the system's load adaptability and safety. Simultaneously, the connection method between the first sliding rod 240 and the first fixed rod simplifies the assembly process between the first movable frame 24 and the second movable frame 25 and the lifting platform 21 and the base 22. During maintenance, the movable frames can be easily separated by disassembling the first mounting rod 241 or the first fixed rod, facilitating inspection and replacement, and reducing maintenance complexity and cost.

[0050] In this embodiment, the lifting platform 21 includes a support plate 210 and folding plates 211 located on both sides of the support plate 210. Each folding plate 211 has a second mounting hole. The base 22 includes a main base plate 220 and two mounting plates 221 oppositely disposed on the main base plate 220. Each mounting plate 221 has a second sliding hole 222. The second movable frame 25 further includes two oppositely disposed second mounting rods 251. The two ends of the second fixed rods are rotatably inserted into corresponding second mounting holes. The top ends of the two second mounting rods 251 are connected to the portions of the two fixed rods extending out of the second mounting holes. The two ends of the second sliding rods 250 are slidably inserted into corresponding second sliding holes 222. The bottom ends of the two second mounting rods 251 are connected to the portions of the two sliding rods 250 extending out of the second sliding holes 222. The second sliding hole 222 is a strip-shaped hole.

[0051] The second sliding rod 250, in conjunction with the second sliding hole 222 on the mounting plate 221, provides precise guidance, ensuring smooth movement of the lifting platform 21 during lifting and lowering, and avoiding unnecessary swaying and offset. Simultaneously, the rotating connection design of the second fixed rod allows the server 3 to maintain balance when lifted and lowered to any height, facilitating precise positioning of the server 3 and simplifying maintenance operations.

[0052] The rapid deployment and recovery mechanism of the second movable frame 25 makes the maintenance and inspection of server 3 faster and more efficient. Maintenance personnel can raise and lower server 3 to a suitable height simply by operating the second movable frame 25 through the drive component 20, without the need for additional lifting equipment. This not only saves time but also improves operational safety and reduces the risk of accidents during maintenance. The connection of the second mounting rod 251, the second fixing rod, and the second sliding rod 250 makes the assembly and maintenance of the lifting platform 21 very convenient. The rotatable and sliding characteristics of these components facilitate rapid on-site installation and adjustment, and also benefit subsequent maintenance and upgrade work.

[0053] In this embodiment, the driving component 20 is a gas spring, which is rotatably connected to the base 22. The output end of the gas spring is connected to the first movable frame 24 or the second movable frame 25, and the control end of the gas spring is connected to the control switch 30 via a pull rope.

[0054] As an actuator based on the principle of gas compression, the gas spring consumes less energy when providing torque and lifting force compared to traditional electric or hydraulic drives. Especially in scenarios that require frequent lifting and lowering of servers, the low energy consumption of the gas spring is even more prominent, which helps to reduce the total energy consumption of the data center and meets the construction requirements of green data centers.

[0055] Furthermore, the rapid response of the gas spring ensures that server 3 can quickly reach the required position during lifting and lowering. Simultaneously, its output force automatically adjusts according to changes in server 3's weight, achieving smooth lifting and lowering. This not only improves maintenance efficiency but also reduces the impact on server 3 during movement, extending the service life of server 3 and the cooling system. Moreover, the gas spring has a self-locking function in its extended state, maintaining a stable support state even when the control switch 30 is not continuously activated, preventing sudden contraction due to external interference. This self-locking mechanism significantly enhances the safety of maintenance operations, preventing damage to server 3 caused by accidental descent.

[0056] The control switch 30 is connected to the gas spring control terminal via a pull rope. Maintenance personnel can control the lifting and lowering of the server 3 simply by operating the control switch 30, eliminating the need for complex control panels or tools and greatly simplifying the operation process. Meanwhile, the rotatable connection design of the gas spring allows it to be folded or stored when not in use, reducing space occupation and facilitating maintenance and inspection.

[0057] like Figure 3 As shown in this application, the chassis body 1 is made of sheet metal, and a liquid cooling connector for connecting liquid cooling equipment is provided on its back, which includes a drain port, a liquid inlet, and a return port. The drain port is connected to a closed connector via a threaded connection for quickly emptying the liquid inside the chassis; the liquid inlet is connected to a blind-fit connector via a threaded connection, which can be matched with a connector on the rack. By pushing the chassis body 1, the connector is connected, thereby enabling the supply of coolant to the receiving cavity. If the server 3 is pulled out, the liquid supply is automatically cut off; the return port is connected to the rack return pipe, allowing the liquid to flow back and achieve liquid circulation. The upper part of the liquid cooling connector has an interface for equipment power and network connection, and the others are connected to the server 3 body via jumpers.

[0058] In this application, server 3 is divided into five independent components. The outer part is a frame that encloses the components, with sliding grooves and fixing buckles for component connection. The upper front part is a hard drive assembly, and the hard drive can be pushed into the assembly via a sliding groove to connect with the back panel. The lower front part is a power supply frame, supporting the installation of a standard power supply. The power supply is pushed in via a sliding groove and connects to the back panel, and its power cable harness is connected to the power interface on the back of the chassis via a front cable tray. The upper rear part is a GPU module, supporting the installation of eight standard GPU modules. A special heatsink is bolted to its upper part, and the modules are connected in pairs via a liquid cooling quick-connect device and connected to the chassis liquid cooling quick-connect connector via liquid cooling pipes. The lower rear part is a CPU module, supporting the installation of two CPUs. A special heatsink is mounted on its upper part and connected to the chassis liquid cooling quick-connect connector via pipes. Both the GPU module and the CPU module can be slid out or pushed in via the frame sliding grooves to facilitate the repair or replacement of the corresponding components. Two crossbeams are installed at the top of the GPU module and connected to the frame. The front crossbeam is equipped with a control switch 30, which is connected to the angle adjustment gas spring via a pull rope. The middle part has a fixing pin that engages with the top cover panel. The rear crossbeam is equipped with an auxiliary handle 31, which provides a reliable grip point for the operator and can be stored and hidden when not in use.

[0059] like Figures 5 to 8 As shown, the liquid-cooled chassis also includes a locking device 4, which is disposed on one side of the chassis body 1. The locking device 4 includes a first locking member 40 and a second locking member 41 that are movably disposed. The first locking member 40 is used to connect with the side wall of the frame, and the second locking member 41 is used to connect with the chassis guide rail on the frame, so that the liquid-cooled chassis is detachably connected to the frame.

[0060] The connection between the first locking member 40 and the side wall of the rack, and the cooperation between the second locking member 41 and the chassis guide rail, work together to ensure the stable installation of the liquid-cooled chassis on the rack. Even in the vibration or slight movement in the data center environment, the liquid-cooled chassis and server 3 can be kept stable, avoiding coolant leakage or hardware damage caused by loosening, and enhancing the safety and reliability of the entire system.

[0061] The locking device 4, through the movable design of the first locking member 40 and the second locking member 41, enables rapid locking and releasing between the liquid-cooled chassis and the rack. Maintenance personnel can easily install and remove the chassis with simple operations, without the need for additional tools or complex locking mechanisms, greatly simplifying the installation and disassembly process and improving maintenance efficiency. Furthermore, the design of the locking device 4 allows the liquid-cooled chassis to fit snugly against the rack, eliminating the need for additional fixing space. Simultaneously, the detachable nature of the locking device 4 facilitates the maintenance and replacement of the server 3, allowing maintenance personnel to quickly adjust the chassis position as needed, optimizing the internal space layout and operational flexibility of the data center.

[0062] It is evident that the liquid-cooled chassis with integrated locking device 4 not only optimizes the installation and maintenance process of server 3 and improves the operational efficiency and security of the data center, but also enhances the overall performance and flexibility of the liquid cooling system by improving its sealing and compatibility.

[0063] In this embodiment, the locking device 4 further includes a main body 42 and a movable part 43. The main body 42 is connected to the side wall of the chassis body 1. The movable part 43 is movably disposed within the main body 42. The first locking part 40 is movably connected to the movable part 43, and the second locking part 41 is connected to the movable part 43. The movable part 43 has a first position, a second position, and a third position. When the movable part 43 is in the first position, the first locking part 40 and the second locking part 41 are respectively connected to the side wall of the rack and the chassis guide rail. When the movable part 43 is in the second position, the first locking part 40 is disengaged from the side wall of the rack, and the second locking part 41 is connected to the chassis guide rail of the rack. When the movable part 43 is in the third position, the first locking part 40 and the second locking part 41 are disengaged from the side wall of the rack and the chassis guide rail, respectively.

[0064] Thus, the three different positions of the movable part 43 provided by the locking device 4—the first position, the second position, and the third position—correspond to the fully locked, partially locked, and fully released states of the chassis and rack, respectively. This multi-level locking mechanism ensures the stability of the server 3 at different operational stages, avoids unexpected displacement or detachment, and greatly improves the operational security within the data center.

[0065] Furthermore, the working states of the first locking element 40 and the second locking element 41 are controlled by the positional changes of the movable element 43. Maintenance personnel can achieve precise control of the locking state through simple actions, such as moving the movable element 43 within the main body 42. This not only simplifies the operation process but also improves the flexibility of data center equipment management, facilitating rapid adjustments to the server 3's status according to actual needs.

[0066] When the movable part 43 is in the second position, the first locking part 40 disengages from the rack sidewall, while the second locking part 41 remains connected to the chassis rails, allowing the server 3 to move within the rack without detaching from the rails. This allows maintenance personnel to perform relatively easy inspections or preliminary maintenance on the server 3, reducing the time and cost of completely disassembling the chassis and improving maintenance efficiency. When the movable part 43 reaches the third position, both the first locking part 40 and the second locking part 41 disengage from the rack. At this point, maintenance personnel can easily remove the liquid-cooled chassis completely from the rack for replacement or upgrades without a complex disassembly process, simplifying equipment maintenance and upgrades and reducing downtime.

[0067] As can be seen, the multi-position adjustment capability of the locking device 4 enables the liquid cooling chassis to be stably fixed in different states. Whether in daily operation, temporary inspection or comprehensive maintenance, it can make reasonable use of space and avoid space waste and unreasonable layout caused by the limitation of equipment fixing method.

[0068] In this embodiment, the movable member 43 is provided with a first limiting opening 430, the main body member 42 is provided with a first mounting opening, the first locking member 40 is rotatably connected to the main body member 42, the first end of the first locking member 40 extends out of the first mounting opening to the outside of the main body member 42, a portion of the first locking member 40 is located within the first limiting opening 430 and is movably disposed, and the second end of the first locking member 40 extends into the movable member 43 from the first limiting opening 430; the movable member 43 is provided with a third sliding hole 431, the main body member 42 is provided with a first connecting post 420, the first connecting post 420 passes through the third sliding hole 431 and is slidably connected to the movable member 43, and the locking device 4 also includes a first elastic member 44, the two ends of the first elastic member 44 being connected to the second end of the first locking member 40 and the first connecting post 420 respectively. The first elastic member 44 is a spring, and the third sliding hole 431 is a strip-shaped hole.

[0069] In this way, the first limiting opening 430 on the movable part 43 cooperates with the first mounting opening of the main body 42, allowing the first locking part 40 to rotate within a preset range. By controlling the position of the movable part 43 relative to the main body 42, the locking and releasing states of the first locking part 40 can be precisely adjusted. This design allows maintenance personnel to quickly lock and unlock the first locking part 40 to the rack side wall without changing the overall position of the chassis, improving operational accuracy and reliability. Furthermore, the use of the first elastic part 44 reduces the need for motors or other complex drive devices, lowers the failure rate of the locking device 4, and simplifies the maintenance process. When replacement or repair is required, the first elastic part 44 is easy to disassemble and replace, reducing maintenance costs and downtime.

[0070] As can be seen, the linkage mechanism between the movable component 43 and the first locking component 40, combined with the self-resetting function of the first elastic component 44, makes the locking operation extremely simple and intuitive. Maintenance personnel only need to push and control the movable component 43 to move it to lock and unlock the first locking component 40, greatly improving the ease of operation and optimizing the user experience for data center maintenance.

[0071] In this embodiment, the movable member 43 is provided with a second limiting opening 432, the main body member 42 is provided with a second mounting opening, and the second locking member 41 includes a mounting section 410 and a locking section 411 connected at an angle. A portion of the mounting section 410 is located within the second limiting opening 432 and is movably disposed therein. The locking section 411 is located within the movable member 43, and at least a portion of the locking section 411 extends from the second mounting opening to the outside of the main body member 42. A second connecting post 421 is provided within the main body member 42, and the locking device 4 further includes a second elastic member 45. The two ends of the second elastic member 45 are respectively connected to the end of the mounting section 410 and the second connecting post 421. The second elastic member 45 is a spring.

[0072] In the above configuration, the mounting section 410 of the second locking member 41 is located within the second limiting opening 432, and its locking section 411 can extend from the second mounting opening to the outside of the main body 42, cooperating with the rack guide rail or other fixed structure to form a precise lock. This design ensures that the server 3 can be firmly fixed when it does not need to be moved, and at the same time, when maintenance or replacement is required, it can smoothly switch from the locked state to the released state by controlling the position of the moving part 43, improving the accuracy and safety of operation. The angled connection design of the mounting section 410 and the locking section 411, as well as the movable setting of the mounting section 410 within the second limiting opening 432, reduces the direct friction between the locking member and the main body 42, reduces the wear of components caused by frequent operation, thereby extending the service life of the locking device 4 and reducing maintenance costs.

[0073] As can be seen, the linkage between the second locking element 41 and the movable element 43, along with the assistance of the second elastic element 45, makes the locking and unlocking operations simple and intuitive. Maintenance personnel only need to control the position of the movable element 43 to lock or release the second locking element 41, without the need for complicated steps or tools, greatly improving the convenience and efficiency of operation.

[0074] In this embodiment, a first guide post 422 is provided inside the main body 42, and a third sliding hole 431 is provided on the movable part 43. The first guide post 422 passes through the third sliding hole 431 and is slidably connected to the movable part 43.

[0075] In this embodiment, a second guide post 423 is provided inside the main body 42, a fourth sliding hole 433 is provided on the movable part 43, and a fifth sliding hole 412 is provided on the second locking part 41. The second guide post 423 passes through the fourth sliding hole 433 and the fifth sliding hole 412 in sequence and is slidably connected to the movable part 43 and the second locking part 41. Both the fourth sliding hole 433 and the fifth sliding hole 412 are strip-shaped holes.

[0076] The first guide post 422 engages with the third sliding hole 431 on the movable part 43, providing a precise guide track for the movement of the movable part 43 along the extension direction of the third sliding hole 431, ensuring the smoothness and positioning accuracy of the movable part 43 during sliding. The connection between the second guide post 423 and the fourth sliding hole 433 and the fifth sliding hole 412 further refines the movement trajectory of the second locking part 41, ensuring the continuity and accuracy of the action during locking, and improving the response speed and operational smoothness of the overall locking device 4.

[0077] Furthermore, the connection between the first guide post 422 and the first locking member 40, and the connection between the second guide post 423 and the second locking member 41, ensures the positional stability of the locking member when performing the locking action. Even if the weight of the server 3 changes or the chassis is subjected to external impact, the reliability of the locking state can be maintained, preventing accidental unlocking and ensuring the safe operation of the server 3.

[0078] As can be seen, through the cooperation of the first guide post 422 with the third sliding hole 431, and the second guide post 423 with the fourth sliding hole 433 and the fifth sliding hole 412, the locking device 4 achieves precise control of the component movement, which not only improves the smoothness of operation and positioning accuracy, but also enhances the stability and durability of the system and simplifies the assembly and maintenance process.

[0079] In this embodiment, the main body 42 is provided with two connecting openings 424 and three spaced-apart limiting holes 425. Along the movement direction of the movable member 43, the three limiting holes 425 are respectively a first limiting hole 425, a second limiting hole 425, and a third limiting hole 425. The locking device 4 also includes a handle 46 and a grip 47. The two ends of the handle 46 pass through the corresponding connecting openings 424 and are connected to the movable member 43. The handle 46 is movably disposed within the connecting openings 424 to drive the movable member 43 to move between the first position, the second position, and the third position. At least a portion of the grip 47 is disposed on the handle. The handle 46 is rotatably connected to the main body 42. An elastic piece 470 is provided on the side of the handle 47 away from the main body 42. The elastic piece 470 contacts the inner wall of the handle 46. A limiting member 471 is provided on the side of the handle 47 close to the main body 42. The limiting member 471 is connected to one of the three limiting holes 425. When the limiting member 471 is connected to the first limiting hole 425, the movable member 43 is in the first position. When the limiting member 471 is connected to the second limiting hole 425, the movable member 43 is in the second position. When the limiting member 471 is connected to the third limiting hole 425, the movable member 43 is in the third position.

[0080] In this embodiment, the limiting member 471 is a spring pin, and the elastic sheet 470 is a steel spring sheet.

[0081] By setting a first limiting hole 425, a second limiting hole 425, and a third limiting hole 425 on the main body 42, and combining this with the different position changes of the moving part 43 (i.e., the first position, the second position, and the third position), three-level locking status management of the locking device 4 is achieved. This multi-level position control allows maintenance personnel to precisely adjust the state of the locking device 4 according to different operational needs, such as fully locked, partially locked, or fully unlocked, thereby improving operational flexibility and efficiency.

[0082] Furthermore, the embedded design of the grip 47 and its connection to the handle 46 make operating the locking device 4 simple and intuitive. Maintenance personnel can simply rotate the grip 47 to slide the handle 46 within the connection opening 424, thereby adjusting the position of the moving part 43. This design reduces operational steps, eliminates the need for complex tools or additional auxiliary equipment, and improves user experience and work efficiency. The combination of the limiting member 471 and the elastic plate 470 gives the grip 47 self-positioning capability. When the limiting member 471 is connected to different limiting holes 425, the elastic plate 470 provides sufficient friction to ensure that the grip 47 does not deviate from its set position due to slight external forces, thus enhancing the stability of the locking device 4 in various locking states.

[0083] As can be seen, through the connection opening 424 and the limiting hole 425 on the main body 42, combined with the coordinated work of the handle 46, grip 47, elastic plate 470 and limiting member 471, the locking device 4 not only simplifies the operation process of maintenance personnel and improves the convenience and efficiency of operation, but also enhances the safety and stability of the equipment through multi-level position control.

[0084] In practical use, when the limiting member 471 is engaged in the first limiting hole 425, the first locking member 40 and the second locking member 41 are pulled by the first elastic member 44 and the second elastic member 45 respectively, and are limited by the movable member 43. At this time, the movable member 43 cannot slide due to its rigid connection with the handle 46, thus the first locking member 40 is restricted from rotating, and the second locking member 41 is restricted to sliding vertically downward. This state is defined as the fully locked state. When the chassis body 1 is in the mounted state, the first locking member 40 is engaged with the buckle on the side wall of the rack, and the second locking member 41 is engaged with the chassis guide rail on the rack, realizing the mutual fixation of the chassis body 1, the guide rail, and the rack.

[0085] When the handle 47 is grasped and the pull handle 46 is slid upward, the limiting member 471 is inserted into the second limiting hole 425. The movable member 43 is driven to slide upward by the pull handle 46. The first limiting opening 430 drives the first locking member 40 to rotate, so that the first locking member 40 is disengaged from the locking hole on the side wall of the frame, and the chassis body 1 can be pulled out from the frame. At this time, the second limiting opening 432 on the movable member 43 is still not in contact with the second locking member 41 because of its movement position. That is, the second locking member 41 is still engaged and fixed with the chassis guide rail on the frame, so that the chassis body 1 cannot be removed from the guide rail.

[0086] When the handle 47 is grasped and the pull handle 46 is slid upward, the limiting member 471 is disengaged from the second limiting hole 425 and slid into the third limiting hole 425. The movable member 43 is driven upward by the pull handle 46. The second limiting opening 432 on the movable member 43 contacts the second locking member 41 and is driven upward by the second limiting opening 432. As a result, the second locking member 41 is disengaged from the chassis guide rail. At this time, the chassis body 1 can be completely pulled away from the chassis guide rail, and the locking device 4 is in the fully disengaged state.

[0087] In this application, when the hard drive or power supply fails, pulling the handle 46 causes the limiting member 471 to be positioned within the second limiting hole 425, disengaging the chassis body 1 from the rack. The chassis body 1 is then pulled out, and the chassis top cover is opened. Next, pressing the control switch 30 causes the lifting device 2 to slowly and evenly rise under the drive of the angle-adjusting gas spring. Once the appropriate height is reached, the control switch 30 is released, and the faulty component is pulled out for replacement. After replacement, pressing the control switch 30 causes the auxiliary handle 31 to flip out and press down to reset the spring. The chassis top cover is then reinstalled, resetting the locking device 4 until the limiting member 471 is positioned within the first limiting hole 425. Pushing in the first locking member 40 and the second locking member 41 automatically engages with the rack, thus re-secured the chassis.

[0088] When the GPU module malfunctions, pull the handle 46 to position the limiting member 471 in the second limiting hole 425, disengaging the chassis body 1 from the rack. Pull out the chassis body 1 and open the chassis top cover. Replace the component. After replacement, reinstall the chassis top cover, reset the handle 46 locking device 4 until the limiting member 471 is in the first limiting hole 425, and push in the first locking member 40 and the second locking member 41 to automatically engage with the rack, thus re-secured the chassis.

[0089] When the CPU module fails or the GPU module is completely replaced, pull handle 46 to position the limiting member 471 in the second limiting hole 425, disengaging the chassis body 1 from the rack. Pull the chassis to the limit of the guide rail travel, then pull handle 46 again to position the limiting member 471 in the third limiting hole 425, disengaging the chassis body 1 from the guide rail. Maintenance personnel can then remove the chassis from the rack and move it to the appropriate maintenance space. During maintenance, open the chassis top cover, then press the control switch 30. The lifting device 2, driven by the angle-adjusting gas spring, will slowly and evenly raise the chassis. Once the lifting device 2 reaches its maximum lifting height, connect the pipes from the back port of the server 3 and pull out the faulty component horizontally for repair or replacement.

[0090] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0091] The control switch 30 on server 3 is connected to the drive component 20 of the lifting device 2, allowing maintenance personnel to control the raising and lowering of server 3 simply by operating the control switch 30 without additional tools. This design greatly simplifies the hardware maintenance process, especially in immersion liquid cooling environments, eliminating the need for manual removal of server 3 from the coolant, avoiding potential liquid leakage and contamination risks, and reducing maintenance time and labor costs. It also solves the technical problem of low maintenance efficiency in existing technologies where manual or external tools are required to remove the motherboard or other components from the liquid when they malfunction in the liquid-cooled chassis of server 3. Furthermore, the open and closed states of the control switch 30 ensure that the output of the drive component 20 can be fixed or released at appropriate times, avoiding the risk of accidental movement of server 3 without human control, thus improving the safety of maintenance operations. This precise control also prevents collisions and damage to other hardware during the raising and lowering of server 3. Meanwhile, the automated lifting device 2 allows the server 3 to be quickly raised when maintenance is needed, eliminating the need for a fixed height of overhead space for manual operation, which significantly improves the space utilization within the chassis. When maintenance is not required, the server 3 can be lowered to its lowest position to maximize the use of the volume within the enclosure, thereby increasing the power density of the data center.
