[0039] See again Figures 1 to 3 as well as Figures 8 to 10The liquid-cooled server enclosure provided in this embodiment of the present invention includes a cabinet body 100, an operation and maintenance component 300, and a lifting component 200. Both the operation and maintenance component 300 and the lifting component 200 are disposed inside the cabinet body 100. An inner liner 110 is provided on the side of the cabinet body 100 adjacent to the lifting component 200. The inner liner 110 contains coolant and electronic equipment 111 immersed in coolant. The operation and maintenance component 300 is used to perform operation and maintenance on the electronic equipment 111. The lifting component 200 is used to lift the electronic equipment 111 and place it on the operation and maintenance platform 310 in the operation and maintenance component 300.

[0040] In this embodiment, the rack body 100 integrates an inner liner 110, a maintenance component 300, and a lifting component 200, with the lifting component 200 positioned between the inner liner 110 and the maintenance component 300. The inner liner 110 is a lidless enclosure structure, adapted to the interior of the rack body 100 and located on one side within the rack body 100. The inner liner 110 contains coolant and several electronic devices 111 (e.g., servers) immersed in the coolant. The inner liner 110, maintenance component 300, and lifting component 200 are tightly arranged within the rack body 100, a compact layout that fully utilizes the limited space inside the rack and improves the space utilization rate of the rack body 100.

[0041] The system comprises an inner tank 110 for containing coolant and housing electronic equipment 111, a maintenance component 300 for performing maintenance on the electronic equipment 111 within the inner tank 110 from within the main cabinet 100, and a lifting component 200 for lifting the electronic equipment 111 from the inner tank 110 and placing it on the maintenance platform 310 within the maintenance component 300 for subsequent maintenance operations. When the electronic equipment 111, submerged in coolant, is operating normally within the inner tank 110, the lifting component 200 and maintenance component 300 are not in operation. When the electronic equipment 111 malfunctions and requires maintenance, it is first lifted by the lifting component 200 and placed on the maintenance platform 310 within the maintenance component 300. Through the coordinated operation of the lifting component 200 and the maintenance component 300, faults in the electronic equipment 111 can be responded to quickly, shortening equipment downtime with an efficient maintenance process and thus reducing the impact on business operations. After the electronic equipment 111 to be maintained has its surface coolant drained on the maintenance platform 310, maintenance personnel can then perform inspection and repair on the platform. The drained coolant on the maintenance platform 310 facilitates inspection and repair by maintenance personnel, ensuring the repair process is unaffected by the coolant and improving work efficiency.

[0042] As can be seen, unlike existing technologies that require a maintenance vehicle to lift the electronic device 111 under test out of the cabinet and place it on an external maintenance platform or transport it to the maintenance room for fault detection and repair, the entire maintenance process in this embodiment does not require lifting the electronic device 111 under test out of the cabinet body 100 (i.e., inside the main structure) to perform testing and repair operations. This achieves integrated and rapid deployment of electronic device 111 operation and maintenance inside the cabinet body 100. Firstly, it reduces the steps of lifting and transporting the device to the outside using a maintenance vehicle, improving maintenance efficiency; secondly, it avoids coolant dripping and wasting after the electronic device 111 is lifted to the outside of the cabinet body 100; and thirdly, it saves on maintenance vehicle operating costs.

[0043] In one embodiment, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the main body 100 of the cabinet includes a main frame 120, a front door 130, a rear door 140, an upper cover 150, a lower cover 160, and a side door 170. The front door 130, rear door 140, upper cover 150, lower cover 160, and side door 170 are all connected to the main frame 120. The front door 130 is located at the front of the main frame 120, the rear door 140 is opposite to the front door 130, the upper cover 150 is located at the top of the main frame 120, the lower cover 160 is opposite to the upper cover 150, and the side door 170 is located on opposite sides of the main frame 120.

[0044] In this embodiment, the main frame 120 is the core load-bearing structure of the cabinet body 100, forming the overall support of the cabinet. The main frame can be made of high-strength metal material, with good durability and compressive strength, used to support and house all components inside the cabinet body 100. The front door 130 is located at the front of the main frame 120 and can be connected to the main frame 120 via hinges to realize the opening and closing function. The front door 130 can be opened and closed as needed to facilitate the installation, disassembly, and maintenance of equipment. The front door 130 can be designed with a structure with ventilation holes to enhance air circulation inside the cabinet body 100 and improve heat dissipation efficiency. In addition, the surface of the front door 130 can be powder coated, which not only enhances the aesthetics but also provides a certain degree of protection, preventing the front door 130 from being corroded by the external environment.

[0045] The rear door 140 is located opposite the front door 130 at the rear of the main frame 120 of the cabinet. The rear door 140 is also connected to the main frame 120 via hinges for opening and closing. The design of the rear door 140 allows for inspection and maintenance of the back of the equipment, while also providing airflow between the inside and outside of the cabinet, further improving heat dissipation. In addition, a cable management rack can be installed on the rear door 140 to organize and secure power cables, data cables, and other cables, making the internal cabling of the cabinet body 100 neater and easier to maintain and manage.

[0046] The top cover 150 is located on top of the main frame 120 of the cabinet. It can be made of the same metal as the main frame 120 and is connected to the top edge of the main frame 120 via hinges or snap-fit ​​connections for easy opening and closing. The bottom cover 160 is located at the bottom of the main frame 120, opposite the top cover 150. The bottom cover 160 is fixedly connected to the main frame 120 to ensure the stability of the cabinet structure. The bottom cover 160 can also consider heat dissipation and ventilation needs, with appropriate ventilation holes selected according to the specific usage environment to ensure the normal operation of the equipment inside the cabinet. Anchor bolts or casters can be installed at the bottom of the bottom cover 160. Anchor bolts are used to fix the main cabinet 100, making it more stable in its installation position and preventing the main cabinet 100 from shaking or shifting; casters facilitate the movement and handling of the cabinet, allowing the main cabinet 100 to be easily moved to a designated location when its position needs to be adjusted. Furthermore, a shock-absorbing pad can be installed on the part of the lower cover 160 that contacts the ground. The shock-absorbing pad is made of rubber or silicone, which can reduce the noise caused by vibration of the main body of the cabinet 100 and protect the ground from being scratched.

[0047] The side doors 170 are located on both sides of the main frame 120 of the cabinet. They can also be connected to the main frame 120 of the cabinet via hinges, enabling them to be opened and closed, so that maintenance personnel can inspect, repair or replace the electronic equipment 111 from the side of the cabinet.

[0048] In one embodiment, such as Figure 2 , Figure 4 as well as Figure 5 As shown, the lifting assembly 200 includes a base 210, a controller 220, a main lifting boom 230, and a telescopic boom 240; the base 210 is connected to the lower cover 160 and is located between the inner liner 110 and the maintenance assembly 300; the bottom of the main lifting boom 230 is vertically connected to the base 210; the telescopic boom 240 is connected to the top of the main lifting boom 230 and is parallel to the lower cover 160; the controller 220 is located on the main lifting boom 230 and is electrically connected to the main lifting boom 230 and the telescopic boom 240.

[0049] In this embodiment, the base 210 is installed on the end face of the lower cover 160 of the cabinet body 100 facing the upper cover 150 by welding or high-strength bolt connection. As the basic support component of the lifting assembly 200, it can be made of high-strength metal material (e.g., high-strength Q345B steel) to give it good compressive and deformation resistance, thereby improving the stability of the lifting assembly 200. The base 210 is located between the inner liner 110 and the maintenance assembly 300 to position the entire lifting assembly 200.

[0050] The bottom end of the main lifting rod 230 is vertically mounted on the base 210. It can be connected to the base 210 by welding, bolting, or other mechanical means to provide vertical load-bearing and guiding functions. The main lifting rod 230 enables the electronic equipment 111 to be tested to move vertically, thus meeting the needs of different lifting heights. The lifting stroke of the main lifting rod 230 is rationally designed based on the height of the electronic equipment 111 inside the cabinet body 100 and maintenance requirements, ensuring that the lifting requirements of the electronic equipment 111 in different positions can be met. The main lifting rod 230 is internally equipped with a screw drive mechanism or a hydraulic lifting mechanism to realize its lifting function. The screw drive mechanism is driven by a motor to rotate the screw, which in turn moves the nut up and down on the screw, thereby realizing the lifting action of the main lifting rod 230. The hydraulic lifting mechanism uses a hydraulic pump to deliver hydraulic oil to the hydraulic cylinder, pushing the piston to raise or lower the main lifting rod 230.

[0051] The fixed end of the telescopic boom 240 is connected to the top of the main lifting rod 230, and its length direction is parallel to the extension direction of the lower cover 160 (that is, the telescopic boom 240 is parallel to the lower cover 160). The boom adopts a multi-section structure design and can be extended and retracted under the drive of the controller 220, so as to flexibly adjust the length of the telescopic boom 240 for precise positioning according to the actual lifting needs.

[0052] The controller 220 is located on the main lifting boom 230 in an easily accessible and maintainable position (e.g., at the bottom or middle). The controller 220 is electrically connected to the main lifting boom 230 and the telescopic boom 240, and is used to control the lifting and lowering movements of the main lifting boom 230 and the telescopic boom 240. The controller 220 may internally include modules such as a motor drive module, a signal processing unit, and a communication interface, supporting multiple control modes including manual control, remote control, and automated control to adapt to the operational needs of different application scenarios.

[0053] Specifically, the controller 220 receives instructions from an external operating terminal (e.g., a remote control) to control the lifting speed and stroke of the main lifting boom 230, the extension length of the telescopic boom 240, and actions such as gripping the electronic device 111. Simultaneously, the controller 220 is equipped with various sensors, such as position sensors and weight sensors, to monitor the working status of the lifting assembly 200 in real time. The position sensors accurately measure the height of the main lifting boom 230 and the extension length of the telescopic boom 240, ensuring that the electronic device 111 can be accurately lifted to the target location (maintenance platform 310). The weight sensors monitor the weight of the lifted electronic device 111; when the weight exceeds the rated load capacity of the lifting assembly 200, the controller 220 will issue an alarm and stop the lifting action to ensure the safety of the electronic device 111.

[0054] In one embodiment, such as Figure 4 As shown, the main lifting boom 230 includes a movable boom 231 and a fixed cylinder 232; the movable boom 231 is movably connected to the fixed cylinder 232; the bottom of the fixed cylinder 232 is connected to the base 210; and the top of the movable boom 231 is connected to the telescopic boom 240.

[0055] In this embodiment, the main lifting rod 230, as the core component of the lifting assembly 200 used to drive the electronic device 111 to move vertically, consists of a movable rod 231 and a fixed cylinder 232. The bottom of the fixed cylinder 232 is fixedly installed on the base 210, forming a vertical support structure. The fixed cylinder 232 can be connected to the base 210 by welding, bolting, or other mechanical connections to enhance the overall load-bearing capacity.

[0056] The movable rod 231 is telescopically fitted inside the fixed cylinder 232 and slides with the fixed cylinder 232, thereby adjusting the lifting stroke. Driven by the controller 220, the movable rod 231 can move up and down along the axial direction of the fixed cylinder 232 to dynamically adjust the boom height and adapt to different working height requirements. The top of the movable rod 231 is connected to the telescopic boom 240, providing a supporting foundation for the subsequent lifting structure.

[0057] In one embodiment, such as Figure 4 , Figure 5 as well as Figure 8 As shown, the telescopic boom 240 includes a telescopic boom 241 and a telescopic cavity 242; the telescopic boom 241 is movably connected to the telescopic cavity 242; the telescopic cavity 242 is connected to the top of the movable rod 231.

[0058] In this embodiment, the telescopic boom 240 is used to lift the electronic device 111 horizontally, and it mainly consists of a telescopic boom 241 and a telescopic cavity 242. The telescopic cavity 242 serves as a guide and storage component for the telescopic boom 241, and its fixed end is connected to the top of the movable rod 231 by welding or bolting to form a stable connection structure. The telescopic cavity 242 can be made of high-strength aluminum alloy or steel, and its interior is designed as a hollow structure to provide space for the extension and retraction of the telescopic boom 241. Inside the telescopic cavity 242, a linear motion telescopic drive device for guiding the telescopic boom 241 is installed, such as an electric push rod, hydraulic cylinder, or ball screw mechanism. That is, the extension and retraction of the telescopic boom 241 are achieved through these drive devices. The telescopic boom 241 is fitted into the telescopic cavity 242 in a sliding or telescopic manner, and one end can freely extend or retract along the direction of the telescopic cavity 242 to expand the lateral working range. The extension length of the telescopic boom 241 can be precisely adjusted by the controller 220 to meet different hoisting distances and load requirements. At the end of the telescopic boom 241 (that is, the free end of the telescopic boom 240, which is opposite to the fixed end), a gripping device specifically for gripping the electronic equipment 111 is installed, such as a mechanical gripper, a vacuum suction cup, or a magnetic suction device. These gripping devices can select the appropriate gripping method according to the shape and material characteristics of the electronic equipment 111 to ensure the safety and stability of the electronic equipment 111 during hoisting.

[0059] In one embodiment, such as Figure 4 as well as Figure 5 As shown, the lifting assembly 200 also includes a hook bracket 250 and a hook 260; the hook 260 is connected to both ends of the hook bracket 250; the middle part of the hook bracket 250 is connected to the telescopic boom 241.

[0060] In this embodiment, the hook bracket 250 and hook 260 serve as the gripping device of the lifting assembly 200, used to grip the electronic device 111 to be tested. The middle part of the hook bracket 250 is connected to the free end of the telescopic boom 240 (i.e., the end of the telescopic boom 241), a configuration that allows for more even force distribution on the hook bracket 250 during lifting. When the telescopic boom 240 moves, the hook bracket 250 can better maintain balance, reducing swaying and deviation.

[0061] The number of hooks 260 and the spacing between adjacent hooks can be set according to actual lifting requirements to accommodate the lifting needs of electronic devices 111 of different sizes. In this embodiment, the number of hooks 260 can be set to two, with the two hooks respectively located at the two ends of the hook bracket 250, acting together on opposite sides of the electronic device 111 to grip it. Compared to a single hook 260, this greatly enhances the stability of the grip. During lifting, the force exerted on the electronic device 111 by the hooks 260 is more balanced, preventing tilting or overturning due to unilateral force, ensuring the safety of the electronic device 111 during lifting and avoiding damage caused by collisions or falls.

[0062] Specifically, under the control of the controller 220, the lifting assembly 200 lifts the electronic device 111 to be tested inside the inner tank 110. The working principle is as follows:

[0063] When it is necessary to inspect or replace the electronic device 111 in the inner tank 110, a lifting command is issued through an operating terminal (such as a control panel, remote control, etc.) connected to the controller 220. After receiving the command, the controller 220, based on the preset program and stored device position information, first activates the lifting drive mechanism in the main lifting boom 230, causing the movable rod 231 set in the fixed cylinder 232 to extend vertically upward, thereby driving the telescopic boom 240 connected to its top to rise to a predetermined height and predetermined position (directly above the device to be inspected in the inner tank 110). The telescopic movement of the main lifting boom 230 can be set with different strokes according to actual needs to ensure that the hook 260 at the free end of the telescopic boom 240 can smoothly grab the electronic device 111 to be inspected.

[0064] Subsequently, the controller 220 drives the telescopic boom 240 to extend laterally, specifically by the telescopic boom 241 sliding out of the telescopic cavity 242 along its axial direction. The free end of the telescopic boom 241 is equipped with a hook bracket 250, and both ends of the hook bracket 250 are equipped with hooks 260, which can accurately align with preset lifting holes, hanging points, or handles on the electronic device 111 to be tested inside the inner liner 110. By fine-tuning the position of the hooks 260, balanced force can be ensured during the lifting process, avoiding structural damage to the electronic device 111.

[0065] After the hook 260 is attached to the electronic device 111, the controller 220 controls the movable rod 231 to rise until the bottom of the electronic device 111 is completely detached from the inner liner 110 and above the top surface of the main cabinet 100. Then, the controller 220 controls the main telescopic rod to rotate 180° in the opposite direction, thereby moving the lifted electronic device 111 to the maintenance side (i.e., above the maintenance platform 310 in the maintenance component 300). Afterward, the telescopic arm 241 can be extended outward or retracted inward to place the electronic device 111 on the maintenance platform 310, allowing maintenance personnel to inspect it. After inspection or replacement, the controller 220 can reverse the process to reset and reinstall the electronic device 111, ensuring its precise repositioning and safe operation.

[0071] In this embodiment, the maintenance platform 310 is detachably and flip-up connected to the main support 320 and located directly above the liquid collection box 340. Its main function is to support the electronic device 111 to be tested and to drain and filter the coolant adhering to the surface of the electronic device 111. Hanging pins 311 on both sides of the maintenance platform 310 are inserted into or hooked into grooves on the telescopic slide rail 330, thereby achieving stable support in different positions. Handles 312 on the maintenance platform 310 are used for easy gripping, pulling out, or flipping of the maintenance platform 310 during manual operation and maintenance.

[0072] The coolant on the surface of the electronic device 111 under test placed on the maintenance platform 310 can be drained through the filter hole 313 into the collection box 340 below it, avoiding contamination of the main cabinet 100 and extending the service life of the main cabinet 100. At the same time, the filtered coolant can be recycled and reused through the collection box 340, saving resources and reducing maintenance costs.

[0073] Specifically, such as Figure 9 As shown, when the maintenance platform 310 is in a vertical state, the handle 312 is located on its end face facing the front door 130, and several filter holes 313 are located on its end face facing the lower cover 160.

[0074] In this embodiment, when the maintenance platform 310 is in a vertical position, the handle 312 is precisely located on its end face facing the front door 130. This design allows maintenance personnel to easily grasp the handle 312 at the front of the cabinet body 100, apply external force to the maintenance platform 310, slide it along the telescopic slide rail 330, or lift it upwards to switch it to a horizontal position. Several filter holes 313 are located on its end face facing the lower cover 160. When the electronic device 111 is placed on the maintenance platform 310, the coolant can naturally flow through the filter holes 313 into the collection box 340 below under the action of gravity, achieving efficient coolant recovery.

[0075] Specifically, such as Figure 10 as well as Figure 11 As shown, when the maintenance platform 310 is in a horizontal state, the handle 312 is located on its end face facing the top cover 150, and several filter holes 313 are located on its end face facing the front door 130.

[0076] In this embodiment, when the maintenance platform 310 is in a horizontal position, the handle 312 is located on its end face facing the upper cover 150. This arrangement facilitates the operator to pull it out of the cabinet body 100 to inspect the electronic equipment 111 placed on the maintenance platform 310. Simultaneously, external force can be applied to adjust its position or it can be lowered to switch to a vertical position. At this time, several filter holes 313 are located on its end face facing the front door 130.
