Description

Technical Field

[0001] This application relates to the field of fluid connector technology, and in particular to a floating joint, a fluid connector, and a server node heat dissipation system. Background Technology

[0002] Currently, with the increasing demand for heat flux density, the heat dissipation requirements for high-power, high-heat-flux-density electronic devices are also constantly improving. Traditional air-cooling technology is gradually failing to meet the needs of rapid heat dissipation. Liquid cooling technology, due to its high heat dissipation efficiency, strong heat dissipation capacity, low noise, compact structure, energy saving and consumption reduction, has become the preferred choice for heat dissipation of high-power, high-heat-flux-density electronic devices and an inevitable trend in the data center field.

[0003] In existing technologies, the connection between liquid cooling pipe joints and server racks usually relies on precise positioning and fixing. However, during frequent server maintenance and upgrades, this rigid connection cannot accommodate the slight displacement that may occur between the node and the rack due to assembly tolerances, mechanical vibrations, etc., which can lead to poor connection sealing and even leakage in high-pressure fluid environments. Summary of the Invention

[0004] This application provides a floating joint, a fluid connector, and a server node heat dissipation system to at least solve the problem of poor sealing or even leakage at the connection point caused by the connection method between pipe joints in the related art.

[0005] This application provides a floating connector, comprising: a base having an interconnected mounting cavity and a through hole, the inner wall of the mounting cavity including a first mating surface; a connector structure including an interconnected connector head and a liquid-passing pipe, the liquid-passing pipe passing through the through hole; a floating assembly including a mating structure, a first stop structure, and an elastic component, the mating structure being sleeved outside the liquid-passing pipe and having a clearance fit with the liquid-passing pipe, the mating structure having a second mating surface adapted to the first mating surface, the second mating surface being located within the mounting cavity; the first stop structure being located within the mounting cavity and connected to the liquid-passing pipe to move synchronously with the liquid-passing pipe; wherein, the first mating surface is an inclined surface or a conical surface; when the floating connector is assembled with the connector to be mated or is in an assembled state, the elastic component is used to apply an elastic force to the first stop structure toward the side of the connector to be mated; when the floating connector is disassembled from the connector to be mated, the elastic component is used to apply an elastic force to the mating structure toward the side of the first mating surface, so that the first mating surface and the second mating surface come into contact, thereby achieving alignment between the connector structure and the base.

[0006] Furthermore, the elastic component includes a first elastic structure and a second elastic structure located on both sides of the first stop structure. The first elastic structure is used to apply a first elastic force to the first stop structure, moving away from the side of the joint to be mated. The second elastic structure is used to apply a second elastic force to the first stop structure, moving towards the side of the joint to be mated. When the floating joint and the joint to be mated are assembled or in an assembled state, the second elastic force is greater than the first elastic force. When the floating joint and the joint to be mated are in a disassembled state, the first elastic structure is used to apply a third elastic force to the mating structure, pressing towards the first mating surface.

[0007] Furthermore, the first elastic structure is a first spring, and the second elastic structure is a second spring, with the elastic coefficient of the second spring being greater than that of the first spring.

[0008] Furthermore, the first mating surface is a first conical surface, and the second mating surface is a second conical surface; the mating structure includes: a tube body; a mating part connected to one end of the tube body, at least a portion of the mating part extending into the mounting cavity, and the outer surface of the mating part forming a second conical surface; wherein, along the direction from the tube body to the mating part, the outer diameter of the second conical surface gradually increases; the tube body is located between the mating part and the connector.

[0009] Furthermore, the mating part has a mounting recess on the side away from the tube body, one end of the first elastic structure extends into the mounting recess and abuts against the mounting recess, and the other end of the first elastic structure abuts against the first stop structure.

[0010] Furthermore, the floating component also includes: a second stop structure disposed within the mounting cavity; wherein the second elastic structure is located between the first stop structure and the second stop structure, and the two ends of the second elastic structure abut against the first stop structure and the second stop structure respectively.

[0011] Furthermore, at least a portion of the outer surface of the liquid-passing pipe is provided with a threaded section, and the first stop structure has an internally threaded hole. The threaded section is threadedly connected to the internally threaded hole to connect the first stop structure and the liquid-passing pipe.

[0012] Further, the base includes: a first housing having a first sub-through hole and a first cavity that are interconnected, with a portion of the inner surface of the first cavity forming a first mating surface; a second housing having a second sub-through hole and a second cavity that are interconnected, with the first cavity and the second cavity abutting to form a mounting cavity; the first sub-through hole and the second sub-through hole being disposed opposite each other to form a through hole.

[0013] Further, the first housing includes: a first cylindrical structure, the inner cavity of which forms a first cavity; a first flange structure disposed on one end of the first cylindrical structure; wherein the end of the first cylindrical structure away from the first flange structure has a first sub-through hole, and the inner circumferential surface of the first cylindrical structure near the first sub-through hole forms a first mating surface; and fasteners are passed through the first flange structure and the second housing to connect the first housing and the second housing.

[0014] Furthermore, the second housing includes: a second cylindrical structure, the inner cavity of which forms a second cavity; and a second flange structure disposed at one end of the second cylindrical structure; wherein the end of the second cylindrical structure away from the second flange structure has a second sub-through hole, and fasteners are passed through the first flange structure and the second flange structure to connect the first housing and the second housing.

[0015] Furthermore, the wire diameter d of the second spring is greater than or equal to 2.0 mm and less than or equal to 3.0 mm, and the mean diameter of the second spring is greater than or equal to 15 mm and less than or equal to 18 mm.

[0016] Furthermore, the first spring and / or the second spring are made of spring steel.

[0017] This application also provides a fluid connector, comprising: a mating joint, including a mating head and a drain pipe connected to each other; a floating joint, wherein the connecting head of the floating joint is threadedly connected to the mating head to enable the drain pipe to communicate with the through pipe; wherein the floating joint is the aforementioned floating joint.

[0018] Furthermore, when the floating joint and the joint to be mated are in the assembled state, the elastic force applied by the elastic component of the floating joint to the first stop structure is greater than the non-leaking squeezing force F between the joint to be mated and the floating joint. The squeezing force F is positively correlated with the water flow pressure P in the drain pipe.

[0019] This application also provides a server node heat dissipation system, including: a base; a liquid-cooled radiator disposed on the base; a fluid connector disposed on the base, wherein the liquid inlet of the fluid connector is connected to the liquid-cooled radiator, the connector to be connected is the outlet connector of the server rack liquid supply system, and the drain pipe of the fluid connector is the outlet pipe of the server rack liquid supply system; wherein, the fluid connector is the aforementioned fluid connector.

[0020] By applying the technical solution of this application, when the floating joint is assembled with the joint to be mated or is in an assembled state, the elastic component applies an elastic force towards the joint to be mated to the first stop structure. This not only achieves floating installation in the front-to-back direction, but also the elastic force can overcome any possible misalignment during joint assembly, ensuring a tight connection between the joints and effectively improving sealing. During this process, since the mating structure and the seat are supported only by the mating between the first and second mating surfaces, the floating joint and the joint to be mated achieve floating installation in the vertical, horizontal, and radial directions, thereby improving the sealing of the pipe joint and preventing leakage. This solves the problem of poor sealing or even leakage at the connection point caused by the connection method of pipe joints in related technologies. Simultaneously, in the disassembled state, the floating joint is not subjected to external forces, only the elastic component. The elastic component applies force to the mating structure, pressing it against the first mating surface. Since the first mating surface is a slope or cone, and the second mating surface is adapted to the first mating surface, the first and second mating surfaces come into contact and are guided, achieving the re-alignment and reset function of the joint structure and the seat.

[0043] 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.

[0044] To address the problem of poor sealing or even leakage at the connection points caused by the connection method of pipe joints in related technologies, this application provides a floating joint, a fluid connector, and a server node heat dissipation system.

[0045] like Figures 1 to 6As shown, the floating connector includes a base 10, a connector structure 20, and a floating assembly. The base 10 has an interconnected mounting cavity 11 and a through hole 12. The inner wall of the mounting cavity 11 includes a first mating surface 111. The connector structure 20 includes an interconnected connector head 21 and a liquid-passing pipe 22, with the liquid-passing pipe 22 passing through the through hole 12. The floating assembly includes a mating structure 30, a first stop structure 40, and an elastic component 50. The mating structure 30 is sleeved outside the liquid-passing pipe 22 and has a clearance fit with the liquid-passing pipe 22. The mating structure 30 has a second mating surface 31 that matches the first mating surface 111, and the second mating surface 31 is located within the mounting cavity 11. The first stop structure 40 is located within the mounting cavity 11 and connected to the liquid-passing pipe 22 to move synchronously with the liquid-passing pipe 22. Wherein, the first mating surface 111 is an inclined surface or a conical surface; when the floating joint and the mating joint 60 are assembled or in an assembled state, the elastic component 50 is used to apply an elastic force to the first stop structure 40 to move toward the mating joint 60; when the floating joint and the mating joint 60 are in a disassembled state, the elastic component 50 is used to apply an elastic force to the mating structure 30 to press toward the first mating surface 111, so that the first mating surface 111 and the second mating surface 31 come into contact, thereby achieving the alignment of the joint structure 20 and the seat 10.

[0046] Applying the technical solution of this embodiment, when the floating joint and the joint to be mated 60 are assembled or in an assembled state, the elastic component 50 applies an elastic force to the first stop structure 40 toward the side of the joint to be mated 60. This not only achieves floating installation in the front-to-back direction, but also the elastic force can overcome the possible offset during joint assembly, ensuring a tight connection between the joints and effectively improving the sealing performance. In the above process, since the mating structure 30 and the seat 10 are supported only by the mating between the first mating surface 111 and the second mating surface 31, the floating joint and the joint to be mated 60 are floating in the up, down, left, and right radial directions, thereby improving the sealing performance of the pipe joint and preventing leakage. This solves the problem in the related art where the connection method between pipe joints leads to poor sealing at the connection point or even leakage. Meanwhile, in the disassembled state, the floating joint is not subjected to external forces, but only to the elastic component 50. The elastic component 50 applies force to the mating structure 30, causing it to press against the first mating surface 111. Since the first mating surface 111 is a slope or a conical surface, and the second mating surface 31 is adapted to the first mating surface 111, the first mating surface 111 and the second mating surface 31 come into contact and are guided, thereby realizing the re-alignment and reset function of the joint structure 20 and the seat 10.

[0047] like Figures 3 to 5As shown, the elastic component 50 includes a first elastic structure 51 and a second elastic structure 52 located on both sides of the first stop structure 40. The first elastic structure 51 is used to apply a first elastic force to the first stop structure 40 to move away from the side of the joint to be mated 60, and the second elastic structure 52 is used to apply a second elastic force to the first stop structure 40 to move toward the side of the joint to be mated 60. When the floating joint is assembled with the joint to be mated 60 or in an assembled state, the second elastic force is greater than the first elastic force. When the floating joint is disassembled from the joint to be mated 60, the first elastic structure 51 is used to apply a third elastic force to the mating structure 30 to press toward the side of the first mating surface 111. In this way, when the floating joint is assembled with the mating joint 60 or in the assembly state, the second elastic force is greater than the first elastic force, which makes the floating joint contact the mating joint 60 more tightly, improving the sealing effect and effectively preventing coolant leakage at the connection. In the disassembled state, the third elastic force applied by the first elastic structure 51 causes the mating structure 30 to automatically return to its original position and align with the first mating surface 111, ensuring that the joint can be quickly and accurately aligned when reassembled, reducing poor sealing and joint damage caused by assembly misalignment.

[0048] In this embodiment, the elastic component 50 allows the floating connector to float in multiple directions during assembly and disassembly to accommodate minor positional differences that may exist between the server node and the rack connector, ensuring adaptability and reliability in different installation environments. Simultaneously, the automatic adjustment function of the elastic component 50 simplifies the assembly steps of the floating connector, reduces the error rate caused by manual operation, and minimizes the risk of damage to the floating connector during assembly and disassembly, thereby improving maintenance efficiency and operational safety.

[0049] In this embodiment, the first elastic structure 51 is a first spring, and the second elastic structure 52 is a second spring, with the elastic coefficient of the second spring being greater than that of the first spring. This difference in elasticity between the first and second springs allows the greater force generated by the second spring during assembly to effectively push the first stop structure 40 towards the mating joint 60, ensuring a tight contact between the joint structure 20 and the mating joint 60, thereby improving the sealing of the connection. Simultaneously, in the disassembled state, the smaller elastic coefficient of the first spring allows for a gentler realignment of the mating structure 30 with the first mating surface 111, achieving automatic reset of the joint structure. This reduces the position adjustment time during reassembly, improves assembly efficiency, and also reduces the risk of component damage due to rough handling.

[0050] like Figure 4 and Figure 5As shown, the first mating surface 111 is a first conical surface, and the second mating surface 31 is a second conical surface. The mating structure 30 includes a tube body 32 and a mating part 33. The mating part 33 is connected to one end of the tube body 32, and at least a portion of the mating part 33 extends into the mounting cavity 11. The outer surface of the mating part 33 forms a second conical surface. The outer diameter of the second conical surface gradually increases along the direction from the tube body 32 to the mating part 33. The tube body 32 is located between the mating part 33 and the connector 21. This contact design between the first and second conical surfaces allows the mating part 33 to automatically return to its centered position and precisely align with the first mating surface 111 even if there is a slight misalignment in the joint structure during disassembly, thanks to the guiding effect of the conical surfaces. This significantly reduces the misalignment during reassembly. Simultaneously, the conical surfaces allow the floating joint to float radially and axially to a certain extent during assembly. This elastic floating capability can adapt to irregular positional changes between the server node and the rack connector, ensuring a tight connection under various conditions and improving the sealing performance of the connection.

[0051] In this embodiment, the expansion of the tapered contact area helps to distribute stress more evenly, reduces damage to sealing materials or wear of joint components caused by excessive local stress concentration, extends the service life of the floating joint, and enhances the reliability of the system.

[0052] like Figures 3 to 5 As shown, the mating part 33 has a mounting recess 331 on the side opposite to the tube body 32. One end of the first elastic structure 51 extends into the mounting recess 331 and abuts against it, while the other end of the first elastic structure 51 abuts against the first stop structure 40. This mounting method ensures stable support of the first spring within the joint structure 20, while precisely applying a first elastic force to the first stop structure 40 on the side opposite to the mating joint 60. This not only helps maintain the stability of the joint structure 20 but also ensures that the joint structure 20 can smoothly return to its center position during disassembly, achieving automatic centering. Simultaneously, the mounting recess 331 provides a precise positioning point for the first spring, ensuring that in the disassembled state, the spring can effectively cause the mating part 33 to move along a predetermined path, realign with the first mating surface 111, and automatically reset to its initial position. This reduces position adjustments during reassembly, improves assembly efficiency, and lowers the risk of poor sealing due to misalignment.

[0053] In this embodiment, when the floating joint and the mating joint 60 are assembled, the first spring can provide sufficient force to keep the joints in close contact. Even under the influence of minor external vibrations or thermal expansion and contraction, it can maintain a good sealing state, effectively prevent coolant leakage, and improve the overall reliability of the liquid cooling system.

[0054] like Figures 3 to 5As shown, the floating assembly also includes a second stop structure 70. The second stop structure 70 is disposed within the mounting cavity 11; wherein, a second elastic structure 52 is located between the first stop structure 40 and the second stop structure 70, with both ends of the second elastic structure 52 abutting against the first stop structure 40 and the second stop structure 70 respectively. Thus, during assembly, the aforementioned arrangement of the second spring can apply sufficient second elastic force to push the first stop structure 40 toward the mating joint 60, ensuring that the floating joint generates sufficient pressure during assembly, achieving a tight, leak-free connection. Simultaneously, the second stop structure 70 limits the maximum compression of the spring, preventing over-compression that could lead to spring failure or damage, ensuring the stability and control accuracy of force distribution.

[0055] In this embodiment, in the disassembled state, the first elastic structure 51 causes the mating structure 30 to automatically return to the center. At this time, the second spring, with the cooperation of the second stop structure, maintains continuous elastic support for the joint structure, ensuring that the joint structure can stably stay in the optimal alignment position when there is no external force, thus providing a guarantee for the next assembly.

[0056] like Figure 2 As shown, at least a portion of the outer surface of the liquid-passing pipe 22 is provided with a threaded section 221, and the first stop structure 40 has an internally threaded hole 41. The threaded section 221 is threadedly connected to the internally threaded hole 41 to connect the first stop structure 40 and the liquid-passing pipe 22. This threaded connection provides a reliable mechanical lock between the liquid-passing pipe 22 and the first stop structure 40, ensuring a secure connection between them and effectively preventing loosening caused by vibration or external impact, thus improving the rigidity and stability of the entire floating assembly structure. At the same time, the threaded connection design makes the assembly of the first stop structure 40 and the liquid-passing pipe 22 simple and quick, allowing for easy disassembly without additional tools, facilitating daily maintenance, inspection, and replacement, while reducing component damage caused by disassembly tools and improving maintenance efficiency.

[0057] like Figures 2 to 5 As shown, the base 10 includes a first housing 13 and a second housing 14. The first housing 13 has a first through-hole and a first cavity that communicate with each other, and a first mating surface 111 is formed on a portion of the inner surface of the first cavity. The second housing 14 has a second through-hole and a second cavity that communicate with each other. The first cavity and the second cavity are mated to form a mounting cavity 11; the first and second through-holes are aligned to form a through-hole 12. This separate design of the first housing 13 and the second housing 14, with precise mating to form the mounting cavity, not only simplifies the manufacturing process but also ensures the stability and mechanical strength of the base 10, effectively resisting external impacts and vibrations, maintaining structural integrity, and extending service life. Simultaneously, the alignment of the first and second through-holes to form the through-hole 12 ensures smooth fluid flow and reduces fluid resistance.

[0058] In this embodiment, the independent design of the first housing 13 and the second housing 14 makes the assembly and disassembly of the floating components more convenient. When maintaining or replacing parts, they can be disassembled individually without damaging the entire structure, greatly facilitating daily inspection and repair, and reducing maintenance costs and time consumption.

[0059] like Figure 3 and Figure 5 As shown, the first housing 13 includes a first cylindrical structure 131 and a first flange structure 132. The inner cavity of the first cylindrical structure 131 forms a first cavity, and the first flange structure 132 is disposed on one end of the first cylindrical structure 131. The end of the first cylindrical structure 131 away from the first flange structure 132 has a first sub-through hole, and the inner circumferential surface of the portion of the first cylindrical structure 131 near the first sub-through hole forms a first mating surface 111. Fasteners 80 are inserted through the first flange structure 132 and the second housing 14 to connect the first housing 13 and the second housing 14. Thus, the first cylindrical structure 131 not only forms the first cavity, but its structural features also increase mechanical strength, ensuring the stability of the seat 10 under external loads, vibrations, and temperature changes. The first flange structure 132, by increasing the local material thickness, further enhances the durability and deformation resistance of the first housing 13.

[0060] In this embodiment, the first mating surface 111 and the second mating surface 31 form a tight contact. Through the self-guiding and self-sealing characteristics of the conical surface, the sealing performance of the floating component is significantly improved, ensuring that the coolant will not leak from the connection, and reducing the maintenance frequency and cost.

[0061] In this embodiment, the first flange structure 132 is provided with a threaded hole so that the fastener 80 can be inserted, thereby realizing the quick connection and disassembly of the first housing 13 and the second housing 14, thus avoiding complex welding or bonding processes, simplifying the assembly steps, and also facilitating future maintenance and component replacement.

[0062] like Figure 3 and Figure 5As shown, the second housing 14 includes a second cylindrical structure 141 and a second flanged structure 142. The inner cavity of the second cylindrical structure 141 forms a second cavity, and the second flanged structure 142 is disposed on one end of the second cylindrical structure 141. The end of the second cylindrical structure 141 away from the second flanged structure 142 has a second sub-through hole. Fasteners 80 are passed through the first flanged structure 132 and the second flanged structure 142 to connect the first housing 13 and the second housing 14. In this way, the second cylindrical structure 141 and the first cylindrical structure 131 are connected through corresponding flanged structures and fasteners 80, ensuring precise alignment and a stable connection between the two housings, thereby improving the assembly accuracy and structural stability of the entire base 10. Simultaneously, the second sub-through hole and the first sub-through hole are aligned to form a through hole 12, allowing for smooth flow of coolant.

[0063] In this embodiment, the threaded hole on the second flange structure 142 matches the threaded hole on the first flange structure 132, which facilitates the insertion of the fastener 80 and enables quick assembly and disassembly of the housing.

[0064] Optionally, the wire diameter d of the second spring is greater than or equal to 2.0 mm and less than or equal to 3.0 mm, and the mean diameter of the second spring is greater than or equal to 15 mm and less than or equal to 18 mm. This wire diameter selection ensures that the second spring has high structural strength and load-bearing capacity while maintaining its flexibility. It not only ensures sufficient elastic restoring force but also makes the second spring less prone to permanent deformation or fatigue fracture under large stress, thereby improving the overall reliability and lifespan of the floating joint to support the free movement and automatic reset of the floating components. Simultaneously, the aforementioned mean diameter selection allows for precise control of the spring's elastic coefficient, adjusting the spring force according to actual working conditions. This ensures sufficient but not excessive pressure is generated during the assembly of the floating joint with the mating joint 60 (node ​​water pipe joint and cabinet joint), avoiding unnecessary damage to the connecting components, while also ensuring sufficient sealing pressure to prevent coolant leakage.

[0065] In this embodiment, the wire diameter d of the second spring is 2.5 mm, and the mean diameter of the second spring is 16 mm. These values ​​balance the size of the second spring with the required spring force, allowing the second spring to operate effectively within a limited space without occupying excessive internal space. This ensures a reasonable layout of the liquid cooling assembly and the normal operation of other components.

[0066] Optionally, the first and / or second springs are made of spring steel. Spring steel possesses high strength, high elasticity, and good toughness, enabling the first and / or second springs to withstand large loads without easily undergoing permanent deformation. This ensures that the first and / or second springs maintain stable elasticity and shape during repeated compression and extension cycles, improving their service life and reliability. Simultaneously, spring steel provides a highly linear force-displacement relationship within a certain deformation range, ensuring that the first and / or second springs always function as expected during floating installation, providing accurate pressure and guaranteeing good connection and sealing performance.

[0067] In this embodiment, both the first spring and the second spring are made of spring steel.

[0068] like Figures 1 to 5 As shown, this application also provides a fluid connector, including a mating connector 60 and a floating connector 200. The mating connector 60 includes a connector head 61 and a drain pipe 62 connected to each other. The connector head 21 of the floating connector 200 is threadedly connected to the connector head 61, so that the drain pipe 62 communicates with the through pipe 22. The floating connector 200 is the aforementioned floating connector.

[0069] In this embodiment, the connector 21 of the floating connector 200 and the connector 61 to be connected form a tight mechanical contact through a threaded connection, which improves the sealing performance of the connection point, effectively prevents coolant leakage at the connection, and ensures the normal operation and efficiency of the liquid cooling system. Meanwhile, the fluid connector adopts a combination design of the connector to be mated and the floating connector, which not only improves the reliability and sealing performance of the connection, but also enhances the adaptability and flexibility of the connector through floating and automatic reset functions, simplifies the maintenance process, reduces operating costs, and ultimately optimizes the overall thermal management effect of the server liquid cooling system.

[0070] In this embodiment, when the floating connector 200 and the mating connector 60 are in the assembled state, the elastic force applied by the elastic component 50 of the floating connector 200 to the first stop structure 40 is greater than the leakage-proof compressive force F between the mating connector 60 and the floating connector 200. The compressive force F is positively correlated with the water flow pressure P in the drain pipe 62. Thus, since the elastic force applied by the elastic component 50 is always greater than the compressive force F required to achieve a seal, a tight contact between the floating connector 200 and the mating connector 60 is ensured. Even under high water flow pressure P, coolant leakage can be effectively prevented, improving the overall sealing performance of the system. Simultaneously, the compressive force F is positively correlated with the water flow pressure P in the drain pipe 62. As the coolant pressure increases, the sealing compressive force between the connectors also increases accordingly. This allows the connector to adapt to various coolant pressure conditions, ensuring a good seal under any pressure, enhancing the connector's adaptability and flexibility.

[0071] like Figure 6 The diagram shows the relationship between the water flow pressure P of the UQDB06 blind-mating fluid connector and the leak-proof compressive force F between the mating connector 60 and the floating connector 200. The horizontal axis represents the water flow pressure P within the drain pipe 62, and the vertical axis represents the leak-proof compressive force F required for the mating connector 60 and the floating connector 200 to achieve the desired fit. The second spring has 5 effective coils, and when compressed by 6mm, it generates an elastic force of approximately 112N, which is greater than the leak-proof compressive force F.

[0072] like Figure 1 and Figure 7 As shown, this application also provides a server node heat dissipation system, including a base 90, a liquid-cooled radiator 100, and a fluid connector. The liquid-cooled radiator 100 is mounted on the base 90, and the fluid connector is mounted on the base 90. The liquid inlet pipe 22 of the fluid connector is connected to the liquid-cooled radiator 100. The connector head 61 is the outlet connector of the server rack liquid supply system, and the drain pipe 62 of the fluid connector is the outlet pipe of the server rack liquid supply system. The fluid connector is the aforementioned fluid connector.

[0073] In this embodiment, by directly connecting the liquid pipe 22 to the liquid coolant radiator 100, the coolant can flow between the two without obstruction, optimizing the heat exchange path, reducing flow resistance, and accelerating the coolant circulation rate, thereby improving the heat dissipation efficiency of the server node. Simultaneously, the fluid connector, combining the precise fit between the floating joint 200 and the mating joint 60, along with the reliable sealing force provided by the elastic component, effectively prevents coolant leakage, ensuring the stable operation and long-term reliability of the liquid cooling system.

[0074] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0075] When the floating joint is assembled with the joint to be mated, or in the assembled state, the elastic component applies an elastic force to the first stop structure toward the joint to be mated. This not only achieves floating installation in the front-to-back direction, but also overcomes any possible misalignment during assembly, ensuring a tight connection between the joints and effectively improving sealing. During this process, since the mating structure and the seat are supported only by the fit between the first and second mating surfaces, the floating joint and the joint to be mated achieve radial floating installation in all directions, thereby improving the sealing of the pipe joint and preventing leakage. This solves the problem of poor sealing or even leakage at the connection point caused by the connection method of pipe joints in related technologies. Simultaneously, in the disassembled state, the floating joint is not subjected to external forces, only the elastic component. The elastic component applies force to the mating structure, pressing it against the first mating surface. Since the first mating surface is a slope or cone, and the second mating surface is adapted to the first mating surface, the first and second mating surfaces come into contact and are guided, achieving the re-alignment and reset function of the joint structure and the seat.
