Description

Technical Field

[0001] This application belongs to the field of liquid cooling connector technology, specifically relating to a liquid cooling quick connector with multi-degree-of-freedom floating components and connector structure. Background Technology

[0002] Liquid cooling technology, leveraging the physical property that liquids have a much higher specific heat capacity than air, offers significant advantages in heat dissipation efficiency and has gradually become the mainstream cooling solution for high-power heat-generating scenarios such as data centers, high-performance servers, industrial cabinets, and electronic equipment. With the continuous increase in computing power demands and the ever-increasing power density of equipment, the reliability and maintainability of liquid cooling systems are increasingly becoming key factors restricting the industry's development. In liquid cooling systems, quick-connect fittings, as core components connecting cooling pipes and enabling rapid on / off switching of coolant, need to withstand frequent plugging and unplugging during equipment maintenance and component replacement. Their performance directly affects the operational safety and maintenance efficiency of the entire liquid cooling system.

[0003] Currently, most quick-connect fittings widely used in liquid cooling systems employ rigid fixing structures. These fittings are typically fixed within the cabinet using rigid structures, with a fixed insertion direction, making precise alignment of the male and female ends during insertion difficult. However, in practical engineering applications, liquid cooling fittings face various complex conditions: firstly, dimensional tolerances and processing errors are unavoidable during manufacturing, resulting in variations in size, end design, sealing methods, and quality between different manufacturers; secondly, thermal expansion and contraction caused by temperature changes during equipment operation lead to multi-dimensional thermal displacement in the piping system; furthermore, in applications such as data centers, equipment operates under high-frequency vibration environments for extended periods. Liquid cooling piping is typically fixed through multiple binding points, making the joint connection rigid, which can easily exceed the material's fatigue strength under high-frequency vibration, leading to failure.

[0004] Under the combined effect of the above factors, existing rigid liquid cooling connectors reveal the following prominent problems: First, the connectors lack flexibility. Most existing liquid cooling connectors are fixed structures, lacking the necessary angle and position adjustment capabilities, and cannot achieve adaptive docking when there are angular deviations or axial offsets between the male and female ends. When there is an angle between the male and female connectors, the sealing surface on the connector is subjected to uneven pressure, easily damaging the sealing surface of the quick-connect connector, affecting its sealing performance, and leading to coolant leakage. Once coolant leaks, it will not only corrode nearby components and pollute the system environment, causing a decrease in insulation and voltage withstand performance, but in severe cases, it may also cause short circuits or open circuit faults in the circuit system.

[0005] Secondly, joints are susceptible to manufacturing errors and thermal deformation. Because existing joints lack effective deformation compensation mechanisms, deformations and errors caused by dimensional tolerances, assembly errors, and thermal expansion and contraction during operation cannot be absorbed or mitigated by the joint itself, easily leading to stress concentration at the joint. Especially in liquid cooling systems with complex piping layouts and limited installation space, rigid joints cannot adapt to installation deviations and thermal displacements in the piping system, further exacerbating the stress state at the joint.

[0006] Third, joints are prone to damage due to stress variations. Existing rigid liquid cooling joints experience constantly changing stress under conditions such as vibration, thermal cycling, and insertion / removal operations, which cannot be effectively released. Long-term alternating stress can cause fatigue damage to the joint material and even stress corrosion cracking. Damage to the joint not only leads to poor flow and reduced cooling efficiency in the liquid cooling system, but in severe cases, it can also cause excessive temperature rise and burn out system equipment.

[0007] Fourth, the connectors cannot achieve automatic reset and reliable mating after connection. Existing liquid-cooled connectors are locked in position after each insertion and lack automatic reset functionality. When reconnecting after equipment maintenance, if minor deviations from the previous connection are not eliminated, the accumulated deviations will make subsequent connections more difficult. As relevant tests show, some quick-connect products exhibit a failure to automatically return the pull ring to its original position after approximately 300 insertions and removals, resulting in inability to lock the connection properly and requiring manual intervention.

[0008] In summary, existing liquid cooling joint technologies, due to their rigid, fixed structures, lack flexible deformation compensation and automatic reset capabilities. This makes them ill-suited to effectively address deformation and stress issues arising from complex operating conditions such as production errors, thermal expansion and contraction, and vibration shocks. Consequently, they severely impact the connection reliability, sealing safety, and service life of liquid cooling systems. Therefore, there is an urgent need to develop a novel liquid cooling joint structure that ensures joint flexibility, automatically compensates for deformation errors, achieves automatic reset, and ensures reliable connection, thereby overcoming the aforementioned shortcomings of existing technologies. Summary of the Invention

[0009] The purpose of this application is to provide a liquid-cooled quick-connect multi-degree-of-freedom floating component and connector structure, which solves the problem that existing liquid-cooled connectors cannot effectively cope with deformation and stress caused by complex working conditions such as production errors, thermal expansion and contraction, vibration and impact.

[0010] The objective of this application is achieved through the following technical solution: A liquid-cooled quick-connect multi-degree-of-freedom floating component includes a fixed base, a connector retaining ring, a floating spring, a bushing, a floating guide sleeve, and a limiting retaining ring. The connector retaining ring is connected to the floating guide sleeve. The bushing is disposed inside the floating guide sleeve and is engaged between the floating guide sleeve and the connector retaining ring along the front and back. The fixed base is connected to the limiting retaining ring. The floating guide sleeve is disposed inside the fixed base and is engaged between the limiting retaining ring and the fixed base along the front and back. Floating springs are provided between the front two sides of the fixed base and the rear two sides of the floating guide sleeve. A circumferential gap is reserved between the fixed base and the floating guide sleeve.

[0011] Furthermore, the fixed base is provided with a floating cavity that runs through the front and back, and guide grooves with forward openings are provided on both sides of the floating cavity. A spring guide pin is provided at the bottom of the guide groove. The floating guide is sleeved in the floating cavity and the guide groove, and the floating spring is sleeved on the spring guide pin.

[0012] Furthermore, the floating cavity has a circular cross-section, and the guide groove has a C-shaped cross-section with the opening facing inward.

[0013] Furthermore, the fixed base is provided with mounting ear plates on both sides, and the mounting ear plates are provided with mounting through holes.

[0014] Furthermore, the connector retaining ring is provided with retaining ring ear plates at the top and bottom, and the retaining ring ear plates are provided with ear plate through holes. The floating guide sleeve is provided with connector screw holes at the top and bottom, and the connector screw passes through the ear plate through holes and connects with the connector screw holes.

[0015] Furthermore, the floating guide sleeve is provided with a bushing cavity that runs through the front and rear, the bushing is disposed in the bushing cavity, and the front end of the bushing cavity is provided with a front limiting edge.

[0016] Furthermore, the floating guide sleeve has spring limiting holes at both rear ends, with floating springs located within the spring limiting holes, and guide holes at both front ends.

[0017] Furthermore, the limiting ring is provided with end plates at the top and bottom, and the end plates are provided with through holes. The fixed base is provided with limiting screw holes at the top and bottom, and the limiting screw passes through the through holes and connects with the limiting screw holes.

[0018] A liquid-cooled quick-connect multi-degree-of-freedom connector structure includes a male connector and a female connector, and also includes the aforementioned liquid-cooled quick-connect multi-degree-of-freedom floating component. The male connector is mounted on a bushing, and the male connector and the female connector are matched to form a quick-connect connector.

[0019] Furthermore, it also includes a chassis, liquid cooling pipes and hoses, with the mounting base located inside the chassis, the hoses connected to the male connector, and the liquid cooling pipes connected to the female connector.

[0020] The beneficial effects of this application are: 1. Achieving multi-degree-of-freedom floating in both axial and circumferential directions, effectively eliminating mating deviations. In this floating component, the bushing is secured between the floating guide sleeve and the connector retaining ring, while the floating guide sleeve is secured between the limiting retaining ring and the fixed base, with a circumferential gap reserved between the fixed base and the floating guide sleeve. The male connector, fitted with the bushing, and the floating guide sleeve can achieve elastic floating in the axial direction under the action of the floating spring; simultaneously, the circumferential gap design allows the floating guide sleeve to drive the male connector to produce a certain deflection and displacement in the circumferential direction. The synergistic effect of the axial and circumferential floating capabilities allows the male connector to automatically adjust its posture according to the position and angle of the female connector during the mating process, effectively compensating for axial offset and angular deviations caused by manufacturing errors, assembly tolerances, thermal expansion and contraction, and pipeline deformation, ensuring smooth insertion of the male and female connectors even in non-ideal alignment conditions.

[0021] 2. Reduces the risk of mating resistance and sealing surface damage, ensuring sealing reliability. Because the male connector has multi-degree-of-freedom floating capability, excessive insertion resistance will not occur due to rigid contact when inserted into the female connector. The compressive force on the sealing surface is uniform, avoiding localized overload and damage such as scratches and crushing of the sealing surface caused by tilted insertion. The integrity and reliability of the sealing structure are effectively guaranteed, significantly reducing the risk of coolant leakage, thereby avoiding secondary failures such as equipment corrosion, decreased insulation performance, and short circuits caused by leakage.

[0022] 3. Buffering vibration and thermal stress, extending the service life of joints and the system. During equipment operation, alternating stress and thermal stress generated by high-frequency vibration and temperature changes are the main causes of joint fatigue failure. This floating component, through the elastic buffering effect of the floating spring and the displacement compensation effect of the circumferential floating gap, can effectively absorb and attenuate the vibration energy and thermal expansion displacement from the pipeline, preventing the formation of rigid stress concentration points at the joint. Stress is released in a timely manner, significantly delaying the fatigue damage process of the joint material, thereby significantly extending the service life of the joint and the entire liquid cooling system.

[0023] 4. Automatic reset ensures consistency during multiple insertions and removals. After insertion, the floating structure of the floating spring and floating guide sleeve allows the male connector to automatically return to the preset initial alignment position after each insertion and removal, eliminating the cumulative effect of deviations during multiple insertions and removals. Each connection achieves a consistent floating compensation range, avoiding problems such as insertion and removal difficulties and locking failures caused by accumulated deviations. This ensures reliable connection under high-frequency maintenance operations and significantly improves the maintainability of the liquid cooling system.

[0024] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding the solution of this application, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected by this application, and will not be exhaustively listed here.

Detailed Implementation

[0039] The following non-limiting embodiments are used to illustrate this application.

[0040] Example 1 refer to Figures 1-10 As shown, a liquid-cooled quick connector with multi-degree-of-freedom floating components includes a fixed base 1, a connector retaining ring 2, a floating spring 3, a bushing 4, a floating guide sleeve 5, and a limiting retaining ring 6.

[0041] The fixed base 1 and the limiting ring 6 are the fixed parts in the floating parts. The fixed base 1 and the limiting ring 6 serve as the support for floating. The joint ring 2, the bushing 4 and the floating guide sleeve 5 are the moving parts in the floating parts. The joint ring 2, the bushing 4 and the floating guide sleeve 5 realize specific multi-degree-of-freedom movements. The floating spring 3 is the buffer transition part between the fixed parts and the moving parts. The floating spring 3 realizes flexible buffering between the fixed parts and the moving parts, that is, realizes relative multi-degree-of-freedom floating transition.

[0042] The connector retaining ring 2 is connected to the floating guide sleeve 5. The bushing 4 is located inside the floating guide sleeve 5 and is secured between the floating guide sleeve 5 and the connector retaining ring 2 along its front and back. The connector retaining ring 2 fixes the bushing 4 inside the floating guide sleeve 5, thus forming a rigid integral structure with the connector retaining ring 2, the bushing 4, and the floating guide sleeve 5. The bushing 4 is used to tightly fit the male connector 7. During installation, the male connector 7 is installed in the inner cavity of the floating guide sleeve 5 by fitting the bushing 4, and then the connector retaining ring 2 provides axial positioning for the male connector 7 and the bushing 4.

[0043] The fixed base 1 is connected to the limiting ring 6. The floating guide sleeve 5 is located inside the fixed base 1 and is secured between the limiting ring 6 and the fixed base 1 along its front and rear sides. Floating springs 3 are provided between the front two sides of the fixed base 1 and the rear two sides of the floating guide sleeve 5. By compressing the floating springs 3, the axial position of the floating guide sleeve 5 can be changed, thereby achieving axial floating. A circumferential gap 14 is reserved between the fixed base 1 and the floating guide sleeve 5. With the differential compression and misalignment of the floating springs 3 arranged on both sides, the circumferential position of the floating guide sleeve 5 can be changed, thereby achieving circumferential floating.

[0044] During installation, the rigid assembly formed by the floating guide sleeve 5 and the male connector 7 is installed into the fixed base 1. Simultaneously, the floating springs 3 on both sides are installed inside the floating guide sleeve 5 and then into the fixed base 1. The floating guide sleeve 5 is then confined within the fixed base 1 by the limiting ring 6. Due to the action of the floating springs 3, the floating guide sleeve 5, with the male connector 7 installed, can float axially. A circumferential gap is designed between the floating guide sleeve 5 and the fixed base 1, allowing the male connector 7 to float circumferentially.

[0045] Existing technologies cannot guarantee the flexibility of joints, which can easily lead to deformation and errors at the joint due to factors such as production errors. Then, damage can be caused by stress changes, making it impossible to achieve automatic reset and reliable docking after connection. This floating component overcomes the above problems by floating in the axial and circumferential directions.

[0046] The fixed base 1 has a through-hole floating cavity 101. Guide grooves 102 with forward openings are provided on both sides of the floating cavity 101. The floating guide sleeve 5 is disposed within the floating cavity 101 and the guide grooves 102, thus the floating guide sleeve 5 is installed through the floating cavity 101 and the guide grooves 102. The through-hole design of the floating cavity 101 ensures the internal connection of the pipeline. The guide groove 102 is only open at its front end. The rear end of the floating guide sleeve 5 is limited by the bottom structure of the groove. Then, a limiting retaining ring 6 is connected to the front end of the fixed base 1, which limits the front end of the floating guide sleeve, thus achieving the locking and installation of the floating guide sleeve 5 in the front-rear direction.

[0047] The floating cavity 101 and guide groove 102 are designed with a circumferential gap 14 between themselves and the floating guide sleeve 5, so as to enable the floating guide sleeve 5 to drive the male connector 7 to float circumferentially. The floating cavity 101 and guide groove 102 together form a cross-shaped cross-section cavity, ensuring the left-right symmetry of the overall structure and improving the stability of the floating component. Preferably, the floating cavity 101 has a circular cross-section, and the guide groove 102 has a C-shaped cross-section with the opening facing inward. The guide grooves 102 on the left and right sides are arranged symmetrically to ensure that the floating guide sleeve 5 has a large degree of freedom of floating within the cavity, and to ensure smooth and stable floating sliding.

[0048] The bottom of the guide groove 102 is provided with a spring guide pin 103, and the floating spring 3 is sleeved on the spring guide pin 103. The spring guide pin 103 assists the compression movement of the floating spring 3 to ensure smooth axial compression / springing. At the same time, the spring guide pin 103 prevents the floating spring 3 from being excessively deviated in circumferential movement.

[0049] The fixed base 1 has mounting ears 105 on both sides, and mounting ears 105 have mounting holes 106 to achieve fixed installation of the fixed base 1 on the chassis 8. Preferably, the fixed base 1 and the mounting ears 105 are an integral structure and are symmetrically arranged on the lower sides of the fixed base 1, so that the fixed base 1 and the mounting ears 105 together form a convex profile in the front-back direction.

[0050] The connector retaining ring 2 has a circular structure. The central annular hole is used for internal pipe passage and connection. At the same time, the diameter of the central annular hole is smaller than the outer diameter of the bushing 4 and the male connector 7, ensuring the retaining ring 2's blocking effect on the bushing 4 and the male connector 7.

[0051] The connector retaining ring 2 is provided with retaining ring ear plates 201 at the top and bottom. The connector retaining ring 2 and the retaining ring ear plates 201 are an integral structure. The retaining ring ear plates 201 are formed by the connector retaining ring 2 extending horizontally to the front end from the top and bottom, and the retaining ring ear plates 201 are arranged symmetrically from top to bottom. The connector retaining ring 2 and the retaining ring ear plates 201 together form a U-shaped structure with the opening facing forward, so that the connector retaining ring 2 can be fastened on the floating guide sleeve 5, ensuring that the overall installation structure is compact.

[0052] The floating guide sleeve 5 has joint screw holes 505 at the top and bottom, and the joint screw holes 505 are located at the rear end of the floating guide sleeve 5 and are arranged symmetrically at the top and bottom. The retaining ring ear plate 201 has a vertical ear plate through hole 202. The joint screw 12 passes through the ear plate through hole 202 and is threaded to the joint screw hole 505. One joint screw 12 is arranged at the top and one at the bottom. Then the joint retaining ring 2 is locked to the floating guide sleeve 5 by two screws, so that the bushing 4, the floating guide sleeve 5 and the male connector 7 are assembled into a rigid assembly.

[0053] The floating guide sleeve 5 has a through-hole 501 with a circular cross-section. The bushing 4 is located inside the bushing cavity 501. The front end of the bushing cavity 501 has a front limiting edge 502, which limits and locks the front end of the bushing 4. The rear end of the floating guide sleeve 5 is connected to a connector retaining ring 2, which also limits and locks the rear end of the bushing 4, thus achieving the locking and installation of the bushing 4 in the front-rear direction.

[0054] The floating guide sleeve 5 has spring limiting holes 503 on both rear ends. The floating spring 3 is located in the spring limiting holes 503, which are stepped and used for spring pre-limiting. The floating guide sleeve 5 has guide holes 504 on both front ends. The guide holes 504 are flared and used for guiding and straightening the male and female connectors during mating. The spring limiting holes 503 and guide holes 504 are connected, which facilitates processing and also facilitates ventilation inside and outside during floating.

[0055] The floating guide sleeve 5 has a concave profile along its vertical direction to allow the guide holes 504 on both sides to guide and fit first, and then the intermediate male connector 7 to connect. The overall profile of the floating guide sleeve 5 along its front-back direction matches the overall profile of the floating cavity 101 and the guide groove 102, that is, the floating guide sleeve 5 forms a cross-shaped cross section. Preferably, the middle part of the floating guide sleeve 5 has a circular cross section, and the two sides have symmetrical C-shaped cross sections with openings facing inward.

[0056] The limiting ring 6 is a square structure with a central circular hole. The central circular hole is used for internal pipe passage and connection. At the same time, the diameter of the central circular hole is smaller than the outer contour dimension of the floating guide sleeve 5, ensuring the limiting ring 6's blocking effect on the floating guide sleeve 5. The directional structure of the limiting ring 6 is used to limit and lock the entire floating guide sleeve 5, preventing the limiting structure from completely covering the floating guide sleeve 5.

[0057] The limiting retaining ring 6 is provided with retaining ring end plates 601 at the top and bottom. The limiting retaining ring 6 and the retaining ring end plates 601 are an integral structure. The retaining ring end plates 601 are formed by the limiting retaining ring 6 extending horizontally to the rear end from the top and bottom, and the retaining ring end plates 601 are arranged symmetrically from top to bottom. The limiting retaining ring 6 and the retaining ring end plates 601 together form a U-shaped structure with the opening facing backward, so that the limiting retaining ring 6 can be fastened to the fixed base 1, ensuring that the overall installation structure is compact.

[0058] The fixed base 1 has limiting screw holes 104 at the top and bottom, which are located at the front end of the fixed base 1 and arranged symmetrically. The retaining ring end plate 601 has an end plate through hole 602. The limiting screw 13 passes through the end plate through hole 602 and is threaded to the limiting screw hole 104. Two limiting screws 13 are arranged at the top and two at the bottom. The limiting retaining ring 6 is locked to the fixed base 1 by four screws, and the floating guide sleeve 5 is locked in the fixed base 1 along the front and back.

[0059] Example 2 refer to Figures 1-13 As shown, a liquid-cooled quick-connect multi-degree-of-freedom connector structure includes a male connector 7, a chassis 8, a liquid-cooling pipe 9, a female connector 10, and a flexible hose 15, and also includes the liquid-cooled quick-connect multi-degree-of-freedom floating component of Embodiment 1.

[0060] The male connector 7 is tightly fitted and fixed inside the bushing 4, and at the same time, it works with the connector retaining ring 2 to achieve locking and limiting, that is, the male connector 7 is also locked between the connector retaining ring 2 and the floating guide sleeve 5 along the front and back. The male connector 7 and the female connector 10 match to form a quick-connect connector, realizing a multi-degree-of-freedom floating connection.

[0061] The mounting base 1 is located inside the chassis 8, and the mounting screws pass through the mounting holes 106 of the mounting ear plate 105 and are screwed to the chassis 8 for fixation. The liquid cooling pipe 9 is connected to the female connector 10, and coolness is supplied to the female connector 10 through the liquid cooling pipe 9. Then, the female connector 10 supplies coolness to the male connector 7. The flexible hose 15 is connected to the male connector 7, and coolness is supplied to the electrical components inside the chassis through the flexible hose 15.

[0062] The fixed base 1 is fastened to the base of the chassis 8 with two screws. A floating component is arranged on the left and right sides of the chassis 8. The male connector 7 of the floating component is connected to the bottom of the chassis via a flexible hose 15 to achieve pipe connection and form a complete liquid loop. Two liquid cooling pipes 9, which are the water distributor pipes, are also arranged on the left and right sides. A connector guide pin 11 is arranged on the liquid cooling pipe 9 along the mating direction. The chassis 8 with the floating components assembled is guided by the connector guide pin 11, specifically by the guide pin 11 and the guide hole 504, to achieve the alignment and connection of the male connector 7 and the female connector 10.
