Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a server rack. Background Technology

[0002] With the rapid development of artificial intelligence, big data and other fields, the computing power demand of servers continues to rise. The thermal design power of core components such as CPU and GPU has exceeded 500W, and the heat dissipation requirements of server racks are constantly increasing.

[0003] In related technical solutions, server racks generally adopt liquid cooling heat dissipation solutions. However, current liquid-cooled server racks mostly adopt a distributed liquid cooling pipeline design. The connection between the liquid cooling plate and the main delivery pipeline is mostly done manually, which is inefficient. Moreover, due to the differences in manual operation, the connection quality between the liquid cooling plate and the main delivery pipeline varies greatly during the connection process. Summary of the Invention

[0004] This application provides a server rack to at least solve the problem in the related art that the connection between the heat dissipation device and the pipeline of the server rack needs to be manually connected.

[0005] This application provides a server rack, including: The cabinet has installation positions inside; A carrier device for carrying a server, the carrier device being installed at the mounting position; A heat dissipation device is disposed on the support device, and the heat dissipation device is used to dissipate heat from the server supported by the support device; A delivery pipeline is connected to the heat dissipation device, and the delivery pipeline is used to deliver cooling medium to the heat dissipation device and receive cooling medium flowing out of the heat dissipation device. The preset installation direction of the support device is consistent with the docking direction of the heat dissipation device and the delivery pipeline. When the support device is installed to the installation position along the preset installation direction, the heat dissipation device and the delivery pipeline are docked and connected.

[0006] Through this application, since the preset installation direction of the support device is consistent with the docking direction of the heat dissipation device and the transmission pipeline, and when the support device is installed in the mounting position of the cabinet along the preset installation direction, the heat dissipation device and the transmission pipeline are docked and connected. Therefore, the docking connection between the heat dissipation device and the transmission pipeline can be completed during the installation process of the support device. Thus, the technical problem of manually connecting the heat dissipation device and the transmission pipeline of the server cabinet can be solved, thereby improving the docking efficiency between the heat dissipation device and the transmission pipeline, avoiding the impact of manual docking on the docking quality, and effectively improving the docking accuracy between the heat dissipation device and the transmission pipeline.

[0012] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] This application provides a server rack, including a rack body 1, a support device 4, a heat dissipation device 5, and a transmission pipeline. The rack body 1 has an installation position for mounting the support device 4, which in turn supports a server. The heat dissipation device 5 is located within the support device 4 and is used to cool the server supported by the support device 4. The transmission pipeline is connected to the heat dissipation device 5 and is used to supply cooling medium to the heat dissipation device 5 and receive cooling medium flowing out of the heat dissipation device 5. The connection direction between the heat dissipation device 5 and the transmission pipeline is consistent with a preset installation direction of the support device 4. During the installation of the support device 4 to the installation position along the preset direction, the heat dissipation device 5 simultaneously completes the connection with the transmission pipeline.

[0014] like Figure 1 As shown, vertical frames 2 are provided on the left and right sides inside the cabinet 1. A connector 3 is provided between the vertical frames 2 for detachable connection with the support device 4. The support device 4 can be guided along the connector 3 and inserted into the corresponding installation position.

[0015] In actual use, the carrier device 4 is first aligned with the corresponding installation position inside the cabinet 1, and then pushed into the cabinet 1 along the preset installation direction. During this movement, the heat dissipation device 5 gradually approaches the corresponding connection position of the delivery pipeline. Once the carrier device 4 is fully installed in the installation position, the heat dissipation device 5 and the delivery pipeline automatically form a docking connection, thereby establishing a cooling medium circulation path. Since the docking direction of the heat dissipation device 5 and the delivery pipeline is consistent with the preset installation direction of the carrier device 4, it is not necessary to connect the heat dissipation device 5 and the delivery pipeline separately after the carrier device 4 is installed. The installation of the carrier device 4 and the docking of the heat dissipation device 5 and the delivery pipeline can be completed with a single insertion action. During server operation, the cooling medium circulates between the delivery pipeline and the heat dissipation device 5 to cool the server and maintain stable server operation.

[0016] In this specific embodiment, the installation of the server rack's support device 4 and the docking of the heat dissipation device 5 and the delivery pipeline are completed simultaneously. This eliminates the need for manual connection of the liquid cooling pipelines, effectively reducing installation errors caused by manual insertion and improving the connection accuracy, stability, and efficiency of the heat dissipation device 5 and the delivery pipelines. It also prevents liquid cooling leaks due to docking misalignment. Furthermore, the improved connection accuracy reduces the number of disassembly and reassembly operations, lowering the risk of seal aging caused by frequent disassembly and reassembly of the liquid cooling pipelines during long-term maintenance, thereby extending the service life of the server rack.

[0017] Based on the above embodiments, multiple mounting positions can be equally spaced along the height direction inside the cabinet 1, and each mounting position is equipped with a connector 3 for detachable connection with the supporting device 4. For example... Figure 1 As shown, the carrier device 4 is installed on two connectors 3 at the same height and opposite each other. In actual use, the installation position and number of carrier devices 4 can be flexibly selected according to the actual server deployment requirements, so that the server rack can adapt to the installation requirements of servers of different specifications and numbers.

[0018] The connector 3 can be configured as a guide rail structure, and during the installation of the bearing device 4, the bearing device 4 can be directly installed along the guide direction of the connector 3.

[0019] like Figure 12 , Figure 13As shown, ventilation holes are provided on the side of the cabinet 1, and filters 18 are installed at the ventilation holes. The ventilation holes are used to allow air circulation between the inside and outside of the cabinet, providing natural ventilation for the internal equipment of the cabinet 1 and assisting in heat dissipation. The filters 18 are used to filter the air entering the cabinet 1, blocking dust, debris and other objects from entering the cabinet 1, and also facilitating the transmission of alarm sounds.

[0020] like Figure 12 , Figure 13 As shown, a first door 21 and a second door 23 are respectively provided on opposite sides of the cabinet. The first door 21 is at least partially provided with a first tempered glass 22, and the second door 23 is at least partially provided with a second tempered glass 24. Specifically, both the first door 21 and the second door 23 can be rotated. The first door 21 and the second door 23 can be used to close the cabinet 1, serving to prevent dust, moisture, and external interference. The first tempered glass 22 and the second tempered glass 24 allow staff to easily observe the operating status of the internal equipment of the cabinet 1.

[0021] Based on the above embodiments, a heat dissipation channel 6 can be provided inside the heat dissipation device 5. One end of the heat dissipation channel 6 is provided with an inlet pipe 7 extending out of the support device 4, and the other end of the heat dissipation channel 6 is provided with an outlet pipe 8 extending out of the support device 4. The conveying pipeline includes an input pipe 9 and an output pipe 10. The input pipe 9 is provided with a first connecting pipe branch 11 connected to the inlet pipe 7, and the output pipe 10 is provided with a second connecting pipe branch 25 connected to the outlet pipe 8. The ends of the inlet pipe 7 and the outlet pipe 8 are each provided with a first connector assembly 15, and the ends of the first connecting pipe branch 11 and the second connecting pipe branch 25 are each provided with a second connector assembly 16. The first connector assembly 15 and the second connector assembly 16 are used to automatically form a plug-in fit during the installation of the support device 4 to realize rapid connection between the heat dissipation device 5 and the conveying pipeline.

[0022] like Figure 2 As shown, the input pipe 9 and the output pipe 10 can be fixedly installed by setting the fixing bracket 12. One end of the fixing bracket 12 is fixedly connected to the input pipe 9 or the output pipe 10, and the other end is fixedly connected to the cabinet 1.

[0023] like Figure 4 As shown, the support device 4 is equipped with two mounting plates 20. The mounting plates 20 provide mounting points for the server, facilitating the fixing of the server to the support device 4 with bolts. A heat dissipation device 5 is fixedly connected inside the support device 4 with hexagonal socket head cap screws.

[0024] The heat dissipation channel 6 can be located inside the heat dissipation device 5, which can be a liquid cooling plate, allowing the cooling medium to circulate within the heat dissipation channel 6 and exchange heat with and cool the core heat-generating components of the server. Furthermore, the heat dissipation channel 6 can adopt a serpentine flow channel structure, a parallel flow channel structure, or a microchannel structure to increase the heat exchange area between the cooling medium and the liquid cooling plate, thereby improving heat dissipation efficiency. The input pipe 9 and the output pipe 10 can adopt a rigid metal pipe structure to improve the overall pipe strength and pressure resistance.

[0025] In actual use, when the carrier device 4 is installed in the mounting position inside the cabinet 1 along the preset installation direction, the liquid inlet pipe 7 and the liquid outlet pipe 8 simultaneously move closer to the corresponding positions of the input pipe 9 and the output pipe 10. As the carrier device 4 continues to move inward, the first connector assembly 15 gradually aligns coaxially with the second connector assembly 16 and automatically forms a plug-in connection. Specifically, solenoid valves 13 can be installed in both the input pipe 9 and the output pipe 10. After the first connector assembly 15 and the second connector assembly 16 are plugged in, the solenoid valve 13 is opened. The low-temperature cooling medium in the input pipe 9 enters the liquid inlet pipe 7 through the first connecting pipe branch 11, the second connector assembly 16, and the first connector assembly 15, and flows into the heat dissipation channel 6 to exchange heat with the server. After heat exchange, the cooling medium flows into the output pipe 10 through the liquid outlet pipe 8, the first connector assembly 15, the second connector assembly 16, and the second connecting pipe branch 25, and is transported back to the external cooling equipment to form a complete liquid cooling cycle.

[0026] In actual setup, the input pipe 9 and the output pipe 10 can be set along the height direction of the cabinet 1. Multiple first connecting pipe branches 11 connected to the liquid inlet pipe 7 can be set on the input pipe 9, and the multiple first connecting pipe branches 11 can be set at equal intervals along the height direction. Multiple second connecting pipe branches 25 connected to the liquid outlet pipe 8 can be set on the output pipe 10, and the multiple second connecting pipe branches 25 can be set at equal intervals along the height direction, so as to correspond to multiple installation positions. No matter which connector 3 the bearing device 4 is installed to, there is a corresponding first connecting pipe branch 11 that plugs into the liquid inlet pipe 7 and a corresponding second connecting pipe branch 25 that plugs into the liquid outlet pipe 8.

[0027] The above technical solution, by setting a heat dissipation channel 6 inside the heat dissipation device 5 and combining it with the liquid inlet pipe 7, liquid outlet pipe 8, input pipe 9, and output pipe 10 to form a complete liquid cooling circulation loop, can effectively improve the heat dissipation efficiency of the server and meet the heat dissipation requirements of high-power servers operating continuously. Furthermore, the automatic docking structure between the first connector assembly 15 and the second connector assembly 16 allows the liquid cooling circuit to be installed synchronously with the support device 4, avoiding manual connection steps and effectively improving work efficiency.

[0028] Based on the above embodiments, combined with Figure 9 The first connector assembly 15 may include a first insertion tube 1501, a first support 1502, a first sealing element 1504, and a first elastic element 1505. One end of the first insertion tube 1501 is connected to the inlet pipe 7 or the outlet pipe 8, and the other end is used to insert and cooperate with the second connector assembly 16. The first support 1502 is fixedly disposed inside the first insertion tube 1501 and is used to support and position the first sealing element 1504 and the first elastic element 1505. The first support 1502 is provided with a first limiting hole for the first moving rod 1503 to pass through. The other end of the first moving rod 1503 is connected to the first sealing element 1504. The first sealing element 1504 is movably disposed along the axial direction of the first insertion tube 1501 and can switch between a first position and a second position. The first elastic element 1505 is disposed between the first sealing element 1504 and the first support 1502 and is used to provide elastic force for the first sealing element 1504 to move toward the sealing position.

[0029] The second connector assembly 16 includes a second insertion tube 1601, a second support 1602, a second sealing member 1604, and a second elastic member 1605. The second sealing member 1604 remains in a sealed state under the action of the second elastic member 1605. The second support 1602 is fixedly disposed inside the second insertion tube 1601 to support and position the second sealing member 1604 and the second elastic member 1605. The second support 1602 is provided with a second limiting hole for the second moving rod 1603 to pass through. The other end of the second moving rod 1603 is connected to the second sealing member 1604. The second sealing member 1604 is movably disposed inside the second insertion tube 1601 between a third position and a fourth position along the axial direction of the second insertion tube 1601. When the second sealing member 1604 is in the third position, it seals the other end of the second insertion tube 1601. When the second sealing member 1604 is in the fourth position, it releases the seal on the other end of the second insertion tube 1601.

[0030] The first sealing element 1504 and the second sealing element 1604 can abut against each other and move inward synchronously when the first connector assembly 15 and the second connector assembly 16 are inserted, so that a communication passage is formed inside the first insertion tube 1501 and the second insertion tube 1601. Specifically, the first sealing element 1504 and the second sealing element 1604 can be made of corrosion-resistant sealing material to improve the sealing stability under long-term liquid cooling environment. The first elastic element 1505 and the second elastic element 1605 can adopt a compression spring structure to improve the reliability of the sealing element reset.

[0031] In actual use, as the carrier device 4 is gradually inserted into the mounting position along the installation direction, the first insertion tube 1501 gradually approaches the second insertion tube 1601 and achieves coaxial alignment under the action of the guide structure. As the carrier device 4 continues to advance, the first insertion tube 1501 is inserted into the interior of the second insertion tube 1601. The first sealing member 1504 and the second sealing member 1604 first come into contact with each other and move synchronously into their respective interiors under the action of the insertion force. At this time, the first elastic member 1505 and the second elastic member 1605 are gradually compressed. With the further movement of the first sealing member 1504 and the second sealing member 1604, a liquid flow space is gradually formed inside the first insertion tube 1501 and the second insertion tube 1601, and the cooling medium can flow into the heat dissipation device 5 from the input pipe 9 or flow out from the heat dissipation device 5 to the output pipe 10.

[0032] When it is necessary to disassemble the bearing device 4, the bearing device 4 is pulled out in the opposite direction. The first insertion tube 1501 and the second insertion tube 1601 gradually separate. Under the elastic force of the first elastic member 1505 and the second elastic member 1605, the first sealing member 1504 and the second sealing member 1604 move back to the sealing position, thereby automatically cutting off the flow path of the cooling medium and preventing coolant leakage.

[0033] like Figure 9 As shown, a first sealing ring 1506 can also be provided on the side of the first sealing member 1504 facing the opening of the first insertion tube 1501, and a third sealing ring 1606 can be provided on the side of the second sealing member 1604 facing the opening of the second insertion tube 1601. A second sealing ring 1507 and a fourth sealing ring 1607 are provided at the insertion connection between the first insertion tube 1501 and the second insertion tube 1601 to improve the sealing performance of the insertion connection between the first insertion tube 1501 and the second insertion tube 1601.

[0034] In this specific embodiment, the first connector assembly 15 and the second connector assembly 16 automatically remain closed when not connected, effectively preventing cooling medium leakage and improving the safety of the liquid cooling system. Compared to traditional open liquid cooling connectors, this embodiment forms a double-sealed structure through the first sealing member 1504 and the second sealing member 1604. When the supporting device 4 is in the disassembled state, the inlet pipe 7 and the outlet pipe 8 remain closed, thereby preventing coolant leakage and contamination of internal components of the server rack. Furthermore, since the first sealing member 1504 and the second sealing member 1604 move synchronously during the insertion process, the liquid circuit opening process is smoother, reducing instantaneous hydraulic fluctuations and improving the operational stability of the liquid cooling system.

[0035] In one specific embodiment, a positioning component 14 is provided on one of the mounting positions of the cabinet 1 and the supporting device 4, and a snap-fit ​​component is provided on the other to cooperate with the positioning component 14. The snap-fit ​​component is used to form a snap-fit ​​cooperation with the positioning component 14 to achieve positioning and fixation of the supporting device 4 after installation.

[0036] Specifically, the positioning component 14 can be an elastic telescopic structure, and the snap-fit ​​component is a snap-fit ​​groove. When the positioning component 14 corresponds to the snap-fit ​​groove, under the action of the elastic element, the positioning component 14 extends and snaps into the snap-fit ​​groove, thereby realizing the positioning and installation of the bearing device 4. Alternatively, the positioning component 14 can also be configured as other positioning structures that meet the requirements.

[0037] In this specific embodiment, by setting the positioning component 14, the positioning and installation of the bearing device 4 can be realized, the installation accuracy of the bearing device 4 can be improved, and the insertion accuracy of the first connector component 15 and the second connector component 16 can be guaranteed.

[0038] Based on the above embodiments, the snap-fit ​​assembly can include a limiting slot 19 disposed at the mounting position, and the positioning assembly 14 includes two snap-fit ​​parts 1408, a transmission part, and an operating part. The two snap-fit ​​parts 1408 are respectively disposed on the left and right sides of the bearing device 4, and the snap-fit ​​parts 1408 can switch between a fifth position and a sixth position; when the snap-fit ​​part 1408 is in the fifth position, the snap-fit ​​part 1408 is inserted into the limiting slot 19; when the snap-fit ​​part 1408 is in the sixth position, the snap-fit ​​part 1408 is disengaged from the limiting slot 19. The transmission part connects the snap-fit ​​part 1408 and the operating part, and the operating part is used to drive the transmission part to move, thereby driving the snap-fit ​​part 1408 to move or rotate.

[0039] Furthermore, the two locking parts 1408 can extend simultaneously to engage with the limiting slot 19 or retract simultaneously from the limiting slot 19 to improve locking stability.

[0040] It should be noted that the transmission unit in this specific embodiment can be a gear and rack structure, and the operating unit is used to control the rotation of the gear. The switching of the engaging part 1408 between the fifth and sixth positions is achieved by the movement of the rack. Alternatively, the transmission unit can be configured as a flipping structure, and the flipping of the transmission unit drives the engaging part 1408 to switch between different angular positions, with the fifth and sixth positions being different angular positions. Of course, the transmission unit and the operating unit can also be other structures that meet the requirements, which will be determined according to the actual situation and will not be elaborated here.

[0041] In this specific embodiment, the double-sided snap-fit ​​portion 1408 improves the installation stability of the support device 4, ensuring its stable positioning during long-term operation. Furthermore, it enables rapid locking and disassembly of the support device 4, improving server maintenance efficiency. Additionally, the positioning component 14 automatically locks the support device 4 at the same time as the connector 3 is inserted and the first connector assembly 15 and the second connector assembly 16 are docked. This effectively prevents the support device 4 from sliding forward or backward or shifting left or right during server rack operation, indirectly limiting the docking of the first connector assembly 15 and the second connector assembly 16, preventing loosening of the connector assembly, ensuring smooth flow of the liquid cooling pipeline, and improving the overall operational stability of the liquid cooling system.

[0042] In one specific embodiment, such as Figure 8 As shown, the operating unit includes an operating handle 1402, a turntable 1403, and a lever 1404. The operating handle 1402 is rotatably mounted on the front end of the bearing device 4. The turntable 1403 is installed inside the operating handle 1402 and rotates synchronously with the operating handle 1402. Two levers 1404 are arranged opposite each other along the same diameter direction on the turntable 1403, and each lever 1404 is provided with a corresponding lever sleeve 1405. The transmission unit includes a support member 1406, a transmission rod 1407, and a third elastic member 1410. One end of the transmission rod 1407 is connected to a locking part 1408, and the other end is connected to a lever sleeve 1405. The support member 1406 is provided with a limit hole to limit the radial movement of the transmission rod 1407. The third elastic member 1410 is disposed between the support member 1406 and the lever sleeve 1405 to provide a restoring elastic force for the transmission rod 1407.

[0043] Furthermore, the operating handle 1402 can adopt a folding structure to reduce the space occupied at the front end of the support device 4. The turntable 1403 can adopt a disc structure to improve the synchronization of the two shift pins 1404. A slide groove can be provided in the shift sleeve 1405, and the shift pins 1404 can slide along the slide groove. The third elastic element 1410 is a compression spring structure.

[0044] like Figure 8 As shown, the operating handle 1402 is rotatably mounted on the bearing device 4 via the rotating shaft 1401. In order to better position the third elastic member 1410, two shims 1409 can be provided. One shim 1409 contacts the lever sleeve 1405, and the other shim 1409 contacts the support member 1406. The two ends of the third elastic member 1410 abut against the two shims 1409 respectively.

[0045] In actual use, when the operator needs to lock the bearing device 4 in the installation position, first push the bearing device 4 into the installation position and turn the operating handle 1402 to drive the turntable 1403 to rotate synchronously. The lever 1404 on the turntable 1403 then pushes the lever sleeve 1405 closer together in the preset direction. The lever sleeve 1405 further drives the transmission rod 1407 to move, causing the two locking parts 1408 to retract synchronously, preventing the locking parts 1408 from affecting the installation of the bearing device 4. After installation, release the operating handle 1402. Under the elastic force of the third elastic element 1410, the turntable 1403 rotates to the initial position, and the lever 1404 then pushes the lever sleeve 1405 further away. When the carrier device 4 needs to be disassembled, the operating handle 1402 is rotated, causing the turntable 1403 to rotate synchronously. The pin 1404 on the turntable 1403 pushes the sleeve 1405 closer together in a preset direction. The sleeve 1405 further drives the transmission rod 1407 to move, causing the two locking parts 1408 to retract synchronously. This releases the locking parts 1408 from the limiting groove 19. The carrier device 4 can then be pulled out in the opposite direction to the preset installation direction, thus disassembling the carrier device 4.

[0046] With the above technical solution, the movement of the two locking parts 1408 can be controlled simultaneously by rotating only a single operating handle 1402, thereby reducing operational complexity and effectively improving locking efficiency. In addition, the third elastic element 1410 provides an automatic reset function, allowing the support device 4 to automatically return to the locked state after installation, improving the security of server operation. Furthermore, the third elastic element 1410 can also provide a stable locking force, thereby improving the long-term reliability of the positioning component 14.

[0047] In one specific embodiment, the server rack further includes a leakage detection device 17, which includes a collection tank 1701, a drive assembly, and a trigger 1718. The collection tank 1701 is located at the connection between the delivery pipeline and the heat dissipation device 5, and can be used to collect coolant leaked at the connection between the delivery pipeline and the heat dissipation device 5. The collection tank 1701 has an opening and an opening / closing door for closing or opening the opening. The drive assembly is connected to the opening / closing door and is used to drive the opening / closing door to move. The drive assembly is provided with a trigger 1718 that is movable along the installation direction of the support device 4.

[0048] The opening and closing door can adopt a flip-type or sliding structure to improve opening and closing stability. The trigger element 1718 can adopt a rod-shaped structure or a push block structure to improve the contact reliability between it and the bearing device 4. The liquid collection tank 1701 can also be provided with a guide slope inside to facilitate the rapid collection of leaked liquid.

[0049] In actual use, when the carrier device 4 is inserted into the mounting position along the installation direction, the carrier device 4 first contacts the trigger 1718 and pushes the trigger 1718 to move along the installation direction. After the trigger 1718 is activated, the drive assembly drives the opening and closing door to open. Subsequently, the first connector assembly 15 enters the liquid collection tank 1701 and completes the insertion connection with the second connector assembly 16. When the liquid cooling system is operating normally, the liquid collection tank 1701 can provide partial protection for the connector area.

[0050] In this specific embodiment, by setting an opening and closing door, the leakage detection device can be set in the first connecting pipe branch 11 and / or the second connecting pipe branch 25 during actual use. When the carrier device 4 is not installed, the opening and closing door can be controlled to be in the closed state to prevent external impurities from entering the second connector assembly 16, and at the same time assist in sealing to prevent liquid cooling medium leakage when not connected. When the carrier device 4 is installed in the installation position, the first connector assembly 15 and the second connector assembly 16 are in the plugged-in state. The liquid collection tank 1701 can be used to collect the liquid leaked at the connection between the first connector assembly 15 and the second connector assembly 16 to prevent the liquid from spreading to the server motherboard area.

[0051] In one specific embodiment, such as Figure 10 , Figure 11As shown, the opening and closing door includes a baffle 1702, and the drive assembly includes a gear 1707, a first rack 1709, a second rack 1708, a connecting rod assembly 1705, a trigger rod 1717, a fourth elastic element 1716, a first guide bar 1703, a moving seat 1704, a connecting shaft 1706, a connecting block 1710, a second guide bar 1711, a guide rail 1712, a support frame 1713, a first assembly plate 1714, and a second assembly plate 1715. A first guide bar 1703 is fixedly connected to the lower end face of the collection tank 1701. A movable seat 1704 is slidably connected to the first guide bar 1703. Both ends of the movable seat 1704 are rotatably connected to connecting rod assemblies 1705. The outer ends of the connecting rod assemblies 1705 are rotatably connected to the lower end face of the outer end of the baffle 1702. In this specific embodiment, the connecting rod assembly 1705 is a separate connecting rod. A connecting shaft 1706 is rotatably connected to the rear side of the lower end face of the collection tank 1701. A gear 1707 is fixedly connected to the bottom end of the connecting shaft 1706. A second rack 1708 and a first rack 1709 are meshed on both sides of the gear 1707. The inner end of the second rack 1708 is fixedly connected to the movable seat 1704 through a connecting block 1710. A second guide bar is fixedly connected to the lower end face of the first rack 1709. 1711, a guide rail 1712 is slidably connected to the second guide bar 1711, a support frame 1713 is fixedly connected to the lower end face of the guide rail 1712, the top end of the support frame 1713 is fixedly connected to the lower end face of the liquid collection tank 1701, a first assembly plate 1714 is fixedly connected to the side wall of the support frame 1713, a second assembly plate 1715 is fixedly connected to the outer end side wall of the first rack 1709, a fourth elastic element 1716 is fixedly connected between the first assembly plate 1714 and the second assembly plate 1715, a trigger rod 1717 corresponding to the first rack 1709 is slidably connected inside the support frame 1713, a trigger element 1718 is fixedly connected to the end of the trigger rod 1717 away from the liquid collection tank 1701, and the top end of the trigger element 1718 is fixedly connected to or in contact with the inner lower end face of the bearing device 4.

[0052] The leakage detection device 17 is used to open and close in conjunction with the insertion or removal of the support device 4, while simultaneously collecting the leaked liquid cooling medium and triggering an alarm; the first guide bar 1703 provides sliding guidance for the movable seat 1704, and the connecting rod assembly 1705 connects the movable seat 1704 and the baffle 1702 to achieve linkage between the movable seat 1704 and the baffle 1702; the connecting shaft 1706 is rotatably connected to the lower end of the liquid collection tank 1701, and the gear 1707 is fixed to the bottom end of the connecting shaft 1706 and meshes with the second rack 1708 and the first rack 1709 to achieve power transmission; the second guide bar 1711 cooperates with the guide rail 1712 to provide sliding support for the first rack 1709, and the support frame 1713 is fixed to the lower end of the liquid collection tank 1701 to support the guide rail 1712 and related components; the fourth elastic element 1716 connects to The first assembly plate 1714 and the second assembly plate 1715 provide elastic restoring force for the second rack 1708; the trigger rod 1717 is slidably connected in the support frame 1713, and the trigger element 1718 connects the trigger rod 1717 and the bearing device 4. When the bearing device 4 is inserted into the insert frame connector 3, the trigger rod 1717 will first contact and squeeze the first rack 1709, pushing the first rack 1709 to move, driving the gear 1707 to rotate, thereby causing the second rack 1708 to drive the moving seat 1704 to slide, and pulling the baffle 1702 open through the connecting rod assembly 1705, providing space for the insertion and docking of the first insertion tube 1501 and the second insertion tube 1601; when the bearing device 4 is removed, the fourth elastic element 1716 rebounds, driving all components to reset, and the baffle 1702 closes the opening again.

[0053] In this specific embodiment, the opening and closing of the door is purely mechanically driven, requiring no additional electronic drive components. Therefore, the structure is simple, the failure rate is low, and it can still operate normally in the event of a power outage, effectively improving the stability of the door's operation and the long-term operational reliability of the server rack. Furthermore, when the supporting device 4 is disassembled, the baffle 1702 can automatically close under the action of the fourth elastic element 1716, effectively preventing accidental human error.

[0054] In one specific embodiment, the leakage detection device 17 further includes a storage tank 1721 and a converging pipe 1720. A guide pipe 1719 is provided at the bottom of the collection tank 1701, and multiple guide pipes 1719 are connected to the converging pipe 1720, which is connected to the storage tank 1721. The storage tank 1721 contains a first alarm 1723, a first leakage sensor 1724, and a first controller 1725. The first alarm 1723 and the first leakage sensor 1724 are both electrically connected to the first controller 1725. The first leakage sensor 1724 is used to detect whether there is leakage information inside the liquid storage tank 1721. The first controller 1725 is used to control the first alarm 1723 to sound an alarm after detecting leakage information. The liquid storage tank 1721 is also provided with a drain pipe 1722, which extends to the outside of the cabinet 1. The part of the drain pipe 1722 that extends out of the cabinet 1 is provided with a control valve, which is used to control the opening and closing of the drain pipe 1722.

[0055] The liquid storage tank 1721 can be located at the bottom of the cabinet 1 to facilitate natural liquid collection. The first leakage sensor 1724 can be an electrode sensor, a float sensor, or a capacitive sensor to improve the reliability of leakage detection. The first alarm 1723 can adopt an audible and visual alarm structure to improve the fault reminder effect.

[0056] In actual use, when a leak occurs at the joint area between the first connector assembly 15 and the second connector assembly 16, the leaking liquid first enters the inside of the collection tank 1701, flows through the guide pipe 1719 into the converging pipe 1720, and then enters the storage tank 1721. When the first leakage sensor 1724 detects liquid inside the storage tank 1721, it immediately sends leakage information to the first controller 1725. The first controller 1725 then activates the first alarm 1723 to alert staff to handle the situation promptly. Staff can drain the leaking liquid from the storage tank 1721 through the drain pipe 1722. If the first controller 1725 is connected to a data center monitoring platform, it can also upload leakage information to the background monitoring system, allowing staff to remotely view the server rack's operating status. The first controller 1725 can also be set to automatically shut off the solenoid valve 13 when a serious leak is detected to reduce the risk of leakage.

[0057] This specific embodiment enables centralized collection and detection of leaked cooling medium, preventing the leakage from spreading and damaging server equipment. Since multiple collection tanks 1701 are connected to the converging pipe 1720 via guide pipes 1719, leaked cooling medium from different locations can be uniformly guided to the storage tank 1721, improving liquid collection efficiency. Furthermore, through the first leakage sensor 1724 and the first controller 1725, an alarm can be issued immediately upon the occurrence of a leak, thereby improving the timeliness of fault response.

[0058] In one specific embodiment, the leakage detection device 17 includes a collection tank 1701, which is located at the connection between the delivery pipeline and the heat dissipation device 5. Different collection tanks 1701 correspond to different location numbers. The collection tank 1701 is equipped with a second leakage sensor, a location information transmitter, a second alarm, and a second controller. When a leak occurs at the connection between the delivery pipeline and the heat dissipation device 5, the liquid is collected in the collection tank 1701. After the second leakage sensor detects the leakage information, it sends the leakage information to the second controller. The second controller controls the second alarm to issue an alarm message and simultaneously controls the location information transmitter to issue location information. Specifically, the location information transmitter can control the indicator light at the corresponding location to light up or send a location code, etc. The staff can quickly find the connection between the delivery pipeline and the heat dissipation device 5 where the leak has occurred based on the indicator light or location code at the corresponding location, so as to realize timely repair of the leak location.

[0059] The server rack positioning component 14 provided in this application can be extended to various liquid-cooled equipment and cabinet structures that require rapid positioning and synchronous docking, including liquid-cooled server racks, industrial liquid-cooled control cabinets, data center liquid-cooled modules, and vehicle-mounted liquid-cooled equipment cabinets. The positioning component 14's core functions of convenient locking and synchronous positioning can adapt to various scenarios requiring frequent disassembly and assembly of load-bearing components and stable docking, improving equipment assembly and maintenance efficiency, ensuring component operational stability, and adapting to positioning and docking needs in multiple fields.
