Description

Technical Field

[0001] This invention relates to the field of heat dissipation technology, and more particularly to a liquid cooling system and electronic device. Background Technology

[0002] In recent years, with the rapid development of cloud computing, artificial intelligence, and high-performance computing technologies, the power consumption and heat generation of data center servers have been increasing. Traditional air-cooling technology, due to its limited heat dissipation efficiency and high energy consumption, is unable to meet the development needs of data centers for efficient and low-carbon heat dissipation. Liquid cooling technology, with its superior heat dissipation performance and better energy efficiency, has gradually become a key technology for data center cooling systems.

[0003] In existing liquid cooling systems, coolant is distributed to multiple liquid cooling plates via distribution manifolds to cool various high-heat components in servers. Such systems typically involve complex piping connections, such as inlet and outlet pipes, and multiple branch pipes and liquid cooling plates connected to them. When maintenance, replacement, or cleaning is required, such as cleaning scale or replacing damaged liquid cooling plates, water pumps, or heat exchangers, the traditional fixed connections make disassembly extremely cumbersome. Operators usually need to disconnect multiple interfaces one by one, which is not only inefficient but also carries the risk of damaging precision quick-connect fittings or seals, and may lead to decreased system reliability due to coolant leaks. Furthermore, the complex piping structure easily accumulates impurities and scale; if thorough cleaning is not easily performed, long-term operation will affect the system's heat dissipation performance and may even cause blockages in the flow channels.

[0004] Therefore, there is an urgent need to develop a liquid cooling system that can quickly and synchronously connect and disconnect the liquid cooling circuit, thereby greatly simplifying the maintenance process and improving the maintainability and reliability of the system. Summary of the Invention

[0005] This invention provides a liquid cooling system and electronic device to at least solve the problems of inconvenient maintenance and low disassembly efficiency caused by the complex piping connections and numerous interfaces of liquid cooling systems in related technologies.

[0006] This invention provides a liquid cooling system, including a substrate, an inlet pipe, an outlet pipe, a cooler, multiple liquid cooling components, and an opening / closing assembly. The inlet pipe is movably disposed on the substrate and has multiple inlet branches spaced apart along its length. The outlet pipe is movably disposed on the substrate and parallel to the inlet pipe, and has multiple outlet branches respectively opposite to the inlet branches. The cooler is connected between the inlet of the inlet pipe and the outlet of the outlet pipe. The multiple liquid cooling components are respectively connected between corresponding inlet branches and outlet branches, and are configured to be thermally connected to a heat-generating component for cooling the heat-generating component. The opening / closing assembly is disposed on the substrate and connected to the inlet and outlet pipes. The opening / closing assembly is configured to drive the inlet and outlet pipes to move synchronously towards or away from each other, so that the multiple inlet and outlet pipes are simultaneously connected to or disconnected from the cooler and the multiple liquid cooling components.

[0007] The present invention also provides an electronic device, including a housing, a plurality of servers disposed within the housing, such as the liquid cooling system described above, wherein a plurality of liquid cooling components of the liquid cooling system are respectively thermally connected to the heat-generating components of the plurality of servers.

[0008] This invention achieves synchronous connection or disconnection of the cooler and all liquid cooling component interfaces by setting up synchronously movable inlet and outlet pipes and using an opening and closing component to drive the inlet and outlet pipes to move in opposite directions. This significantly improves system maintenance efficiency, avoids the tediousness and risk of seal damage caused by operating each interface one by one, enhances system reliability, and provides convenience for internal cleaning and component replacement, effectively extending the service life of the liquid cooling system.

[0029] Figure 1 A perspective view of a liquid cooling system provided in an embodiment of the present invention; Figure 2 A perspective view of a liquid cooling system with the cooler and liquid cooling components removed, provided for an embodiment of the present invention.

[0030] Embodiments of the present invention provide a liquid cooling system, such as Figure 1 and Figure 2As shown, it includes a substrate 1, an inlet pipe 2, an outlet pipe 3, a cooler 5, multiple liquid cooling components 6, and an opening and closing component 4. The liquid inlet pipe 2 is movably disposed on the substrate 1, and the liquid inlet pipe 2 has a plurality of liquid inlet branch pipes 21 arranged at intervals along the length direction of the liquid inlet pipe 2; the liquid outlet pipe 3 is movably disposed on the substrate 1 and is arranged parallel to the liquid inlet pipe 2, and the liquid outlet pipe 3 has a plurality of liquid outlet branch pipes 31 respectively opposite to the liquid inlet branch pipes 21; the cooler 5 is connected between the inlet of the liquid inlet pipe 2 and the outlet of the liquid outlet pipe 3; a plurality of liquid cooling components 6 are respectively connected between the corresponding liquid inlet branch pipes 21 and liquid outlet branch pipes 31, and are configured to contact the heat-generating components to cool the heat-generating components; the opening and closing component 4 is disposed on the substrate 1 and connected to the liquid inlet pipe 2 and the liquid outlet pipe 3, and the opening and closing component 4 is configured to drive the liquid inlet pipe 2 and the liquid outlet pipe 3 to move synchronously towards or away from each other, so that the plurality of liquid inlet pipes 2 and the liquid outlet pipe 3 are simultaneously connected to or disconnected from the cooler 5 and the plurality of liquid cooling components 6.

[0031] According to the above configuration, by setting up a synchronously movable inlet pipe 2, outlet pipe 3, and linkage opening and closing component 4 on the base plate 1, the synchronous linkage connection or disconnection of the cooler 5 and all liquid cooling component 6 interfaces is realized, which significantly improves the maintenance efficiency and operation convenience of the system, effectively avoids the problems of seal wear, coolant leakage and long maintenance time caused by operating each interface individually in traditional liquid cooling systems, and greatly enhances the reliability, maintainability and service life of the system.

[0032] According to an embodiment of the present invention, the substrate 1 is disposed along a vertical plane and is suitable for connection with the housing of an electronic device or integrally formed with the housing of an electronic device.

[0033] in, Figure 1 The direction perpendicular to substrate 1 is the transverse direction, and Figure 1 The horizontal direction (left-right direction) of the plane on which the middle substrate 1 is located is the vertical direction.

[0034] According to an embodiment of the present invention, the inlet pipe 2 and the outlet pipe 3 are arranged to move in the longitudinal direction along the plane of the substrate 1, and the inlet pipe 2 and the outlet pipe 3 extend in the vertical direction. The inlet pipe 2 is adapted to distribute the coolant from the cooler 5 to a plurality of liquid cooling components 6, and the outlet pipe 3 is adapted to collect the coolant after heat exchange in the plurality of liquid cooling components 6 into the cooler 5.

[0035] In one illustrative embodiment, such as Figure 1 As shown, the liquid cooling system also includes a pump 7, which is located at the inlet of the liquid inlet pipe 2.

[0036] According to an embodiment of the present invention, in the cooling system, after the coolant flows out from the outlet of the cooler 5, it is pumped into the inlet pipe 2 by the action of the pump 7, and flows through multiple inlet branch pipes 21 to be distributed in parallel to each liquid cooling component 6; after exchanging heat with the heat-generating components in the liquid cooling component 6, the coolant carrying heat gathers into the outlet branch pipe 31 and flows into the outlet pipe 3; finally, it returns to the inlet of the cooler 5 through the outlet of the outlet pipe 3, completing a closed loop.

[0037] In one illustrative embodiment, the substrate 1 is further provided with a guiding mechanism, which is suitable for guiding and constraining the movement of the inlet pipe 2 and the outlet pipe 3, ensuring that they move smoothly and synchronously towards or away from each other along a predetermined path. This helps improve the positional accuracy and sealing effect of the inlet branch pipe 21 and the outlet branch pipe 31 when docking with the cooler 5 and the liquid cooling assembly 6, while effectively suppressing possible offset, shaking, or jamming during movement, thereby enhancing the overall operational stability and mechanical durability of the system.

[0038] In one illustrative embodiment, the liquid cooling system further includes multiple sealing units disposed at the connection between the liquid inlet pipe 2 and the liquid outlet pipe 3 and the cooler 5, and at the connection between the liquid cooling assembly 6 and the liquid inlet branch pipe 21 and the liquid outlet branch pipe 31.

[0039] In one illustrative embodiment, the liquid cooling system further includes multiple sealing units, respectively disposed at the connection between the inlet pipe 2 and the cooler 5, the connection between the outlet pipe 3 and the cooler 5, and the connection between each liquid cooling component 6 and its corresponding inlet branch pipe 21 and outlet branch pipe 31. The sealing units are configured to provide a reliable seal when the liquid cooling system is connected, preventing external contaminants from entering the piping system or coolant from overflowing, thereby significantly improving the sealing reliability, environmental adaptability, and maintenance convenience of the liquid cooling system.

[0040] In one illustrative embodiment, quick-release connectors are provided at the connections of the inlet pipe 2 and the cooler 5, the outlet pipe 3 and the cooler 5, and the liquid cooling assembly 6 and the inlet branch pipe 21 and the outlet branch pipe 31. These quick-release connectors are configured to automatically align, lock, or separate the connections during the movement of the inlet pipe 2 and the outlet pipe 3 driven by the opening and closing assembly 4. This allows for the synchronous connection or disconnection of all interfaces without manual operation, greatly improving maintenance efficiency and effectively preventing seal damage or coolant leakage caused by improper manual operation, further enhancing the reliability and safety of the system.

[0041] In one illustrative embodiment, a coolant inlet is provided on the pipeline between the pump 7 and the cooler 5, and a coolant outlet is provided at the bottom of the outlet pipe 3. Both the coolant inlet and the coolant outlet are equipped with control valves to adjust the replenishment and discharge process of the coolant, thereby achieving precise control of the coolant capacity, flow rate and pressure in the liquid cooling system, and facilitating the injection, evacuation and replacement operations during maintenance.

[0042] In one illustrative embodiment, such as Figure 1 and Figure 2 As shown, the opening and closing assembly 4 includes a first driving unit 41, two moving parts 43, and a transmission mechanism 42. The first driving unit 41 is disposed on the substrate 1; the two moving parts 43 are respectively connected to the inlet pipe 2 and the outlet pipe 3; the transmission mechanism 42 is configured to convert the rotational motion of the first driving unit 41 into synchronous linear motion of the two moving parts 43 in opposite directions, so as to drive the inlet pipe 2 and the outlet pipe 3 to move synchronously.

[0043] Specifically, the transmission mechanism 42 converts a single rotary input into a precise synchronous linear output, enabling the synchronous opposite or backward movement of the inlet pipe 2 and the outlet pipe 3. This improves the efficiency and consistency of multi-interface docking, effectively avoiding problems such as misalignment, jamming, or poor sealing caused by asynchronous movement. While ensuring that the interfaces of the cooler 5 and all liquid cooling components 6 are synchronously connected or disconnected, it enhances the stability, reliability, and service life of the liquid cooling system.

[0044] In one illustrative embodiment, such as Figure 2 As shown, the transmission mechanism 42 includes a bidirectional lead screw 421 and a first guide rod 422. The bidirectional lead screw 421 is rotatably disposed on the substrate 1 and connected to the output end of the first drive unit 41; the first guide rod 422 is disposed parallel to the bidirectional lead screw 421 on the substrate 1, and two moving parts 43 are slidably disposed on the first guide rod 422 and threadedly engaged with both ends of the bidirectional lead screw 421.

[0045] According to the above configuration, by using a transmission mechanism 42 composed of a bidirectional lead screw 421 and a first guide rod 422, the rotational motion of the first drive unit 41 is converted into synchronous and opposite linear motion of the two moving parts 43, ensuring that the inlet pipe 2 and the outlet pipe 3 always remain parallel, aligned and stably guided during the movement, effectively eliminating the risk of movement deviation, jamming or asynchrony.

[0046] Furthermore, two mounting seats 11 are provided on the substrate 1. The bidirectional lead screw 421 and the first guide rod 422 both extend longitudinally, and the two ends of the bidirectional lead screw 421 and the first guide rod 422 are stably connected to the substrate 1 through the two mounting seats 11 respectively. This mounting seat 11 structure provides a reliable support foundation for the rotation of the bidirectional lead screw 421 and the fixation of the first guide rod 422, ensuring the rigidity and stability of the overall structure of the transmission mechanism 42.

[0047] In an alternative embodiment, the transmission mechanism 42 includes a pair of gear and rack assemblies. Two racks are respectively arranged parallel to each other on the base plate 1, with their teeth facing each other. The gear set is connected to the output end of the first drive unit 41 and meshes with both racks simultaneously. A first guide rod 422 is arranged parallel to the racks, and two moving parts 43 are respectively fixedly connected to the two racks and slidably disposed on the first guide rod 422. When the first drive unit 41 drives the gear set to rotate, it can synchronously drive the two racks and the moving parts 43 connected thereto to move in opposite directions or away from each other.

[0048] Figure 3 This is a perspective view of a liquid cooling assembly provided in an embodiment of the present invention.

[0049] In one illustrative embodiment, such as Figures 1 to 3 As shown, the liquid cooling assembly 6 includes a liquid cooling unit 61 and two guide pipes 62; one end of each guide pipe 62 is connected to the inlet and outlet interfaces of the liquid cooling unit 61 via an installation assembly 63, and the other end is connected to the corresponding inlet branch pipe 21 and outlet branch pipe 31.

[0050] Specifically, through the modular design of the liquid cooling unit 61 and the guide pipe 62, and with the detachable installation component 63, the liquid cooling unit 61 and the main pipeline (inlet pipe 2 and outlet pipe 3) of the liquid cooling system are quickly and reliably connected and separated, which improves the maintenance and replacement efficiency of a single liquid cooling unit 61, reduces system downtime, and effectively ensures the sealing and flow reliability of the coolant in complex flow channel connections.

[0051] In one illustrative embodiment, the liquid cooling unit 61 includes a housing, a flow channel formed inside the housing, and a thermally conductive contact surface disposed on one side of the housing. The flow channel has an inlet and an outlet, which are respectively used to connect a guide pipe 62 at the liquid inlet end and a guide pipe 62 at the liquid outlet end; the thermally conductive contact surface is used to fit tightly against the surface of the heating element and to continuously remove the heat generated by the heating element through the coolant circulating in the internal flow channel.

[0052] Furthermore, the liquid cooling unit 61 can be adapted to heat-generating elements of different sizes and power to achieve efficient and uniform heat exchange, thereby ensuring that the heat-generating elements operate stably within a safe temperature range.

[0053] In one illustrative embodiment, such as Figure 3 As shown, the liquid cooling assembly 6 also includes a temperature sensing unit 65, which is disposed on the side wall of the liquid cooling unit 61 and is suitable for monitoring the temperature of the liquid cooling unit 61.

[0054] In detail, the temperature sensing unit 65 is disposed on the side wall of the liquid cooling unit 61 or in the area adjacent to the heat-generating component, for real-time monitoring of the temperature change of the liquid cooling unit 61 and feeding the temperature signal back to the control unit of the liquid cooling system, providing a basis for the flow regulation of the coolant, thereby achieving precise temperature control based on the actual heat load.

[0055] Figure 4 A partial cross-sectional view of the valve unit in the guide pipe provided in an embodiment of the present invention; Figure 5 A perspective view of the adjustment component provided in an embodiment of the present invention; Figure 6 for Figure 5 A magnified view of point A of the adjustment component shown.

[0056] In one illustrative embodiment, such as Figures 3 to 6 As shown, the liquid cooling assembly 6 also includes an adjustment assembly 64 and a flow guide pipe 62 disposed at the liquid inlet end of the liquid cooling unit 61, which is used to adjust the flow rate of the coolant flowing through the liquid cooling unit 61 according to the temperature of the liquid cooling unit 61 monitored by the temperature sensing unit 65.

[0057] Specifically, by setting an adjustment component 64 connected to the temperature sensing unit 65, dynamic closed-loop control of the coolant flow rate through the liquid cooling unit 61 is realized. It can quickly respond to and accurately adjust the flow distribution according to the real-time temperature changes of the heating element, thereby ensuring efficient heat dissipation while avoiding overcooling, and improving the temperature control accuracy, energy efficiency and adaptability of the liquid cooling system.

[0058] In one illustrative embodiment, such as Figures 4 to 6 As shown, the regulating assembly 64 includes a valve unit, a drive screw 642, and a second drive unit 641. The valve unit extends partially into the guide tube 62 from the outside of the guide tube 62. The drive screw 642 is rotatably disposed outside the guide tube 62 and is threadedly engaged with the portion of the valve unit located outside the guide tube 62. The second drive unit 641 is configured to drive the drive screw 642 to rotate, thereby moving the valve unit and adjusting the flow cross-sectional area of ​​the guide tube 62.

[0059] In detail, the second drive unit 641 drives the drive screw 642 to rotate, which in turn drives the valve unit that is threaded to it to move radially along the guide pipe 62, thereby changing the depth of the valve unit extending into the guide pipe 62, realizing continuous and precise adjustment of the flow cross-sectional area, and thus controlling the flow rate of the coolant.

[0060] According to the above configuration, the adjustment assembly 64, which consists of the second drive unit 641, the drive screw 642 and the valve unit, enables precise adjustment of the flow cross-sectional area of ​​the guide pipe 62. It can quickly change the coolant flow rate according to the change of heat load, thereby optimizing the system energy efficiency while ensuring heat dissipation efficiency.

[0061] In one illustrative embodiment, such as Figures 4 to 6 As shown, the valve unit includes a valve plate 643, a connecting arm 644, and a second guide rod 645. The valve plate 643 extends into the guide tube 62 at least partially through an opening in the tube wall, and the surface of the valve plate 643 is parallel to the cross-section of the guide tube 62. The connecting arm 644 is located at one end of the valve plate 643 outside the guide tube 62 and is threadedly engaged with the drive screw 642. The second guide rod 645 is arranged parallel to the drive screw 642 outside the guide tube 62, and the connecting arm 644 is slidably arranged on the second guide rod 645.

[0062] According to the above configuration, the valve plate 643 can move smoothly in or out along the cross-sectional direction of the guide tube 62, directly adjusting the flow cross-sectional area; the connecting arm 644 converts the rotational motion of the drive screw 642 into the linear motion of the valve plate 643, and eliminates deflection and jamming through the constraint of the second guide rod 645, ensuring the stability and accuracy of the movement of the valve plate 643, thereby improving the reliability and response efficiency of flow control.

[0063] In one illustrative embodiment, the flow channel cross-section of the guide tube 62 is configured as square, and the valve plate 643 is correspondingly designed as a rectangular plate structure adapted to the square flow channel. The valve plate 643 can move in a vertical direction perpendicular to the flow channel axis, and its plate surface always remains parallel to the flow channel cross-section, thereby achieving continuous and smooth adjustment of the flow cross-sectional area of ​​the square flow channel during movement. This square cross-section design, combined with vertical movement, creates a uniform fit clearance between the valve plate 643 and the flow channel wall, enhancing the guiding and stability of the valve plate 643 during movement, reducing vibration and noise caused by eddies or disturbances, and facilitating processing and sealing design.

[0064] In one illustrative embodiment, such as Figures 4 to 6 As shown, in one illustrative embodiment, the adjustment assembly 64 further includes a fixing plate 647 and a fixing platform 648. The fixing plate 647 is disposed on the upper part of the guide pipe 62, the lower fixing platform 648 is disposed on the lower part of the guide pipe 62, the drive screw 642 is rotatably disposed between the upper fixing plate 647 and the lower fixing platform 648, and the second drive unit 641 is fixedly mounted on the upper fixing plate 647.

[0065] In detail, both the drive screw 642 and the second guide rod 645 are configured to extend in the vertical direction.

[0066] The fixed plate 647 and the fixed platform 648 provide a stable and coaxial support base for the drive screw 642 and the second guide rod 645, effectively suppressing the radial runout and vibration that may be generated when the screw rotates at high speed, ensuring the smoothness, accuracy and reliability of the valve unit movement process, while improving the overall structural rigidity and service life of the regulating assembly 64.

[0067] In one illustrative embodiment, each liquid cooling assembly 6 is provided with multiple liquid cooling units 61; the guide pipe 62 is provided with multiple connection ports, which are respectively connected to multiple liquid cooling units 61, and the multiple connection ports are respectively provided with drive screws 642 and valve units; the second unit is connected to multiple drive screws 642 through multiple transmission components 646.

[0068] Specifically, according to embodiments of the present invention, such as Figures 1 to 6 As shown, each liquid cooling assembly 6 has two liquid cooling units 61, which are arranged laterally at intervals. Two guide pipes 62 (one at the inlet and one at the outlet) each have two connection ports, which are detachably connected to the two liquid cooling units 61 via mounting components 63. Each connection port is equipped with a drive screw 642 and a valve unit. The second drive unit 641 is mounted on a fixed plate 647 above the guide pipe 62 and includes a dual-head servo motor. Its output ends on both sides are connected to the two drive screws 642 via transmission components 646, simultaneously driving the two drive screws 642 to rotate synchronously, thereby moving the two valve units simultaneously and achieving synchronous adjustment of the coolant flow rate of the two liquid cooling units 61.

[0069] Based on the above configuration, the synchronous and precise control of the coolant flow of two liquid cooling units 61 in the same liquid cooling component 6 is achieved by using single and dual-head servo motors in conjunction with the transmission component 646. This significantly simplifies the drive structure of the two independent cooling circuits, reduces system complexity and cost, and improves the system's reliability, energy efficiency and maintenance convenience while ensuring the heat dissipation balance of each liquid cooling unit 61.

[0070] According to embodiments of the present invention, such as Figure 6 As shown, the transmission component 646 includes a bevel gear set. The bevel gear set includes a first bevel gear and a second bevel gear. The first bevel gear is fixedly mounted on the top end of the drive screw 642, and the second bevel gear is fixedly mounted on the output end of the dual-head servo motor and meshes with the first bevel gear. This bevel gear transmission structure achieves efficient conversion of power direction, accurately transmitting the rotational motion of the motor to the drive screw 642, and features a compact structure, smooth transmission, and high load-bearing capacity.

[0071] Figure 7 A perspective view of the installation components provided in an embodiment of the present invention; Figure 8A perspective view of the installation component provided in an embodiment of the present invention in an unlocked state.

[0072] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the mounting assembly 63 includes at least one connecting unit and a locking unit. Each connecting unit includes a connecting portion 631 and a plug 632. The connecting portion 631 is disposed at the end of the guide tube 62 and has a slot 633 extending laterally. The slot 633 has a notch on one side in the lateral direction. The plug 632 is disposed at the interface of the liquid cooling unit 61 and is engaged in the slot 633 by sliding in the lateral direction. The locking unit is rotatably disposed on the connecting portion 631 and has an unlocked state that allows the plug 632 to be inserted into or removed from the slot 633 in the lateral direction, and a locked state that blocks the notch to prevent the plug 632 from being dislodged from the notch.

[0073] Based on the above configuration, the guide and positioning structure of slot 633 and insert block 632, along with the locking unit, enable rapid docking and reliable locking between the flow guide tube 62 and the liquid cooling unit 61. This not only simplifies the installation and disassembly process of the liquid cooling unit 61 but also significantly improves maintenance efficiency.

[0074] Furthermore, the locking unit, in the locked state, effectively provides lateral mechanical restraint to the slot opening of the slot 633, thereby preventing the insert 632 from dislodging in the opposite direction of insertion. This ensures the connection rigidity and stability of the interface between the guide tube 62 and the liquid cooling unit 61 under coolant pressure or external vibration interference, effectively preventing the risk of accidental loosening or leakage, while also ensuring the convenience of quick unlocking and enhancing the stability of the interface connection. In one illustrative embodiment, the cross-sections of both the slot 633 and the insert 632 are configured as horizontally placed T-shapes.

[0075] In one illustrative embodiment, both the slot 633 and the insert 632 are configured with T-shaped cross-sections that mate with each other. Accordingly, the slot 633 also has an auxiliary notch facing the insert 632, which accommodates the horizontal portion of the insert 632 during its insertion or removal from the slot 633 in the lateral direction. With this configuration, when the slot 633 and the insert 632 are engaged, movement of the insert 632 relative to the slot 633 in the longitudinal direction can be prevented.

[0076] Specifically, the insert 632 can be inserted laterally into the T-shaped slot 633 along the guide tube 62, and the connection interface is mechanically limited in both the longitudinal and vertical directions by the cooperation between the flange of the T-shaped structure and the inner wall of the slot 633. This effectively limits the axial displacement and vertical sway of the insert 632 that may occur under coolant pressure or vibration.

[0077] In an alternative embodiment, the cross-sectional shapes of the slot 633 and the insert 632 can be configured with various complementary geometries to achieve reliable connection and locking. For example, a dovetail cross-section, where the mating surfaces of the insert 632 and the slot 633 form an inclined trapezoidal structure. Utilizing the inclined surface self-locking effect, longitudinal pull-out forces are naturally resisted after insertion, enhancing the holding force of the connection under vibration. Another option is an L-shaped or hook-shaped cross-section, where the block has a bend, and the slot 633 has a corresponding L-shaped or hook-shaped cavity. This shape achieves mechanical interlocking through a hook-like structure, preventing accidental longitudinal loosening of the insert 632.

[0078] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the locking unit includes a first rotating member 634, a second rotating member 635, and a latching mechanism 636. The first rotating member 634 is rotatably connected to the connecting part 631; the second rotating member 635 is rotatably connected to the outside of the connecting part 631 or the guide tube 62; the latching mechanism 636 is disposed at the end of the first rotating member 634. When the locking unit is in the locked state, the latching mechanism 636 can release and lock the first rotating member 634 and the second rotating member 635.

[0079] In this design, the axis of rotation of the first rotating member 634 is offset from its geometric center axis and located at one end of the first rotating member 634, with the axis mounted adjacent to the slot opening of the slot 633. When the first rotating member 634 rotates around this eccentric axis, it generates at least a portion of an asymmetrical oscillating trajectory, creating a locking position that blocks most or all of the slot opening of the slot 633, thereby mechanically limiting the inserted plug 632 and preventing it from reversing and dislodging. When rotated to the unlocked position, the main body of the first rotating member 634 completely moves away from the slot, providing sufficient space for the insertion or removal of the plug 632. This eccentric shaft structure effectively converts rotational motion into blocking and avoidance actions, achieving reliable maintenance of the locked state and rapid release of the unlocked state.

[0080] According to the above configuration, the locking unit cooperates with the releasable latching mechanism 636 through an eccentrically positioned rotating shaft, realizing the effective blocking and release of the slot opening of the first rotating member 634 on the slot 633: In the locked state, the first rotating member 634 reliably covers the slot opening with its eccentric rotation trajectory, forming a mechanical limit on the insert 632 and preventing it from accidentally coming out; the latching mechanism 636 further ensures the locking state between the first rotating member 634 and the second rotating member 635, ensuring the stability of locking the insert 632, improving the stability and safety of the connection, and ensuring reliable locking while taking into account the convenience of operation and clear visibility of the status.

[0081] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the latching mechanism 636 includes a latching block 6361 and an elastic member 6362. The latching block 6361 is slidably disposed in a groove formed at the end of the first rotating member 634. The elastic member 6362 is disposed between the latching block 6361 and the bottom wall of the groove. The end of the second rotating member 635 is provided with a latching groove 6351 that cooperates with the latching block 6361. When the ends of the first rotating member 634 and the second rotating member 635 are opposite each other, the latching block 6361 is driven by the elastic member 6362 to at least partially extend into the latching groove 6351 to prevent the first rotating member 634 and the second rotating member 635 from moving relative to each other.

[0082] Specifically, when the first rotating member 634 rotates to the locked position, and at the same time the second rotating member 635 rotates to the position where the end of the second rotating member 635 is directly opposite the end of the first rotating member 634, the locking block 6361 automatically and at least partially embeds into the slot 6351 under the drive of the elastic member 6362, so that the first rotating member 634 and the second rotating member 635 are engaged with each other to form a mechanical interlock, thereby effectively restricting the relative movement or separation between the two.

[0083] According to the above configuration, the latching mechanism 636 achieves self-locking and rapid release between the first rotating member 634 and the second rotating member 635 through the cooperation of the latching block 6361 driven by the elastic element 6362 and the latching slot 6351. In the locked state, the latching block 6361 automatically embeds into the latching slot 6351 under the action of elastic force, forming a mechanical interlock, effectively resisting vibration or external impact, and ensuring the stable maintenance of the locked state. When unlocking is required, it is only necessary to overcome the elastic force to remove the latching block 6361 from the latching slot 6351, which is simple and reliable. This improves the connection reliability, anti-interference ability, and ease of operation of the locking unit.

[0084] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the latching mechanism 636 also includes a telescopic rod 6363, one end of which is connected to the latching block 6361, and the other end is connected to the bottom wall of the slide groove. An elastic element 6362 is sleeved on the outside of the telescopic rod 6363 and abuts against the bottom wall of the slide groove. The telescopic rod 6363 provides rigid guidance and limitation for the movement of the latching block 6361, ensuring that the latching block 6361 slides smoothly along a predetermined path, avoiding deviation or jamming. The elastic element 6362 provides a continuous preload force to the latching block 6361, ensuring that the latching block 6361 can reliably engage with the latching groove 6351 or reset.

[0085] According to an embodiment of the present invention, the card block 6361 is further provided with an operating protrusion, which extends to the outside or surface of the first rotating member 634 to form an operable area, so as to facilitate the card block 6361 to move against the pre-tightening force of the elastic member 6362 by applying external force manually or with a tool, thereby realizing the rapid separation of the card block 6361 from the card slot 6351 and improving the convenience and efficiency of the unlocking operation.

[0086] In one illustrative embodiment, such as Figure 7 and Figure 8 As shown, the mounting component 63 includes two connection units, which are respectively located in the upper and lower regions of the connection interface between the guide pipe 62 and the liquid cooling unit 61, to jointly form a stable multi-point mechanical connection.

[0087] Specifically, the first rotating member 634 and the second rotating member 635 are configured to independently lock or unlock the slots 633 of the connecting parts 631 of the two connecting units. The first rotating member 634 controls the slots 633 of the upper connecting unit to be covered or exposed, while the second rotating member 635 controls the slots 633 of the lower connecting unit to be locked or released, thereby achieving coordinated or independent locking of the guide tube 62 and the liquid cooling unit 61 at the upper and lower connection points, enhancing the adaptability and operational flexibility of the interface connection.

[0088] Furthermore, when the first rotating member 634 and the second rotating member 635 are both rotated to the locked position and are in a mutually engaged state, they are aligned in the vertical direction and form an overall locking structure. At the same time, they cooperate to block the slots of the upper and lower connecting units, ensuring that the mechanical load borne by the guide pipe 62 and the liquid cooling unit 61 at the upper and lower connection points is evenly distributed.

[0089] Embodiments of the present invention also provide an electronic device, including a chassis, multiple servers, and a liquid cooling system as described above. Multiple servers are arranged side-by-side within the chassis, and the liquid cooling system is integrated inside the chassis. Multiple liquid cooling components 6 are respectively thermally connected to the central processing unit, graphics processing unit, or other high-power heat-generating components of the multiple servers, forming parallel heat dissipation paths for multiple computing nodes. This electronic device achieves uniform and reliable heat dissipation for high-density server clusters through an efficient and compact liquid cooling system, significantly improving equipment operational stability, computing performance, and energy efficiency. It is suitable for scenarios such as data centers, artificial intelligence training platforms, and high-performance computing clusters.

[0090] This invention significantly improves the operational stability and reliability of electronic devices such as servers under complex operating conditions by introducing a multi-pipe liquid cooling system that can be synchronously connected or disconnected, and integrating a highly efficient temperature-adaptive flow control function.
