Description

Technical Field

[0001] This utility model relates to the field of measuring quick-release connectors, and particularly to a device for measuring the separation leakage and trapped air volume of a floating connector. Background Technology

[0002] As server computing performance continues to improve, the heat generated during system operation is also increasing rapidly. Traditional air-cooling solutions are gradually becoming insufficient for high-heat-density servers. Liquid cooling technology, as the primary solution, provides more efficient heat transfer and dissipation capabilities. However, existing liquid cooling architectures still face the following types and challenges:

[0003] 1. Water-to-air architecture: Primarily used for retrofitting existing air-cooled server rooms, this design lowers the barrier to entry by installing rear-door fans and water-cooling pipelines. However, this solution generates significant noise during operation and is difficult to provide a long-term solution.

[0004] 2. Water-to-water architecture: This places higher demands on the pressure resistance and sealing of coolant piping and connectors. For example, in NVIDIA's high-end chips, the closed-loop water-to-water system means that even a tiny leak can lead to system failure and pose a significant risk.

[0005] 3. Immersion cooling architecture: Although it is considered a promising technology for the future, it requires a redesign of the data center structure, careful selection of dielectric fluid, and its application scenarios are more complex, especially in terms of the use of connectors, which presents many challenges.

[0006] Liquid cooling system architectures typically require coolant piping to be laid inside servers or between racks. Quick-release couplings are a key component for easy maintenance, rapid assembly, and module replacement. However, leaks or difficulties in assembling / disassembling quick-release couplings can significantly impact system reliability and maintenance costs.

[0007] Compared to traditional hydraulic systems or ordinary water-cooling solutions, AI servers have much more stringent requirements for the sealing performance of quick-release connectors. Coolant leakage can lead to short circuits or damage to sensitive electronic components, and the economic losses caused by server downtime for repairs often far exceed the cost of the connector itself. Therefore, reducing the possibility of quick-release connector failure and ensuring that the risks during replacement or disassembly are controllable have become important issues in liquid cooling system design. At the same time, reliability testing of quick-release connectors is becoming increasingly important in order to meet the needs of server applications.

[0008] Currently, in the reliability testing of quick-release couplings, fluid loss and air inclusion are two indispensable core indicators.

[0009] 1. Fluid Loss Test: This test measures the average amount of media leakage after the male plug and female socket of a quick-release connector are separated from their mated state.

[0010] 2. Air Inclusion Test: This test measures the amount of air introduced into the medium circuit during the docking process of the quick-release connector.

[0011] One application of quick-release couplings is the floating coupling. In addition to providing the docking functionality of quick-release couplings, floating couplings offer automatic correction for misalignment and displacement during docking. However, one of the reliability tests for floating couplings involves simulating misalignment and displacement conditions to measure separation leakage and trapped air volume.

[0012] Although ISO 18869 provides basic theory and apparatus illustrations for measuring leakage and air carryover in quick-release couplings, its specific details regarding measuring equipment and key components remain incomplete. Furthermore, there are no publicly available and specific dedicated measuring devices on the market, forcing businesses to rely on traditional testing methods and simple apparatus. However, these methods and apparatus have the following drawbacks:

[0013] 1. Instability of the testing process: Traditional devices are mostly operated manually, and the docking and separation actions lack precise control, making the data susceptible to deviation due to human operation.

[0014] 2. Limitations of equipment structure: Existing testing devices are usually only applicable to quick-release couplings of a single size or type, lacking versatility, and cannot simultaneously achieve accurate testing of leakage and trapped air volume, nor can they be used for testing floating couplings.

[0015] 3. Insufficient data accuracy: The impact of bubble interference during the test was not fully considered, resulting in deviations in the trapped air volume data.

[0016] Therefore, there is an urgent need for a device that can address the aforementioned technical deficiencies and improve the accuracy and reliability of testing. Utility Model Content

[0017] The purpose of this invention is to provide a floating joint measuring device that can solve the above-mentioned problems. This device is suitable for simulating floating joints in tilted and displaced states to perform two test operations: leakage and trapped air volume, thereby overcoming the defects and challenges in the prior art.

[0018] To achieve the above objectives, this utility model provides a floating joint measuring device, characterized in that it comprises:

[0019] A sliding device includes a slide group and a fixed seat and a floating joint fixed seat disposed on the slide group.

The upper end of the second measuring tube has a second opening, and the lower end is connected to the adapter and the first connecting unit assembly through a second connecting unit assembly.

[0021] The floating joint measuring device further includes a base, and the slide group is disposed on the base; one end of the adapter is provided with a pipe connection part, and the other end is provided with a test sample connection part; the fixed seat is provided with a groove for placing the adapter.

By simply switching the position of the first or second opening of the first and second measuring tubes, two different tests, namely separation leakage and trapped air volume, can be completed. This is operable and feasible, and can save on testing costs.

[0034] 2. Simple and stable testing operation: The sliding device enables stable advancement of the male and female heads during docking / separation, reducing the impact of test errors caused by uneven human force application, resulting in high test result stability and shortening test time.

[0035] 3. Supports multiple types of floating connectors: Simply replace the corresponding floating connector unit or adapter to test different types and sizes of quick-release connectors.

[0036] 4. Simple component design, easy assembly and replacement: It is equipped with a mounting backplate, such as a perforated plate, to facilitate the replacement of these components fixed on the mounting backplate.

[0037] 5.

The device also includes a fixed backplate for stabilizing the sliding device, measuring pipe assembly, and connecting unit assembly. A vibrator is selectively installed on the fixed backplate to effectively eliminate bubble interference during testing, further improving data accuracy.

[0038] This invention effectively overcomes the various shortcomings of existing technologies, such as the inability to test floating joints, and has practical application prospects. Attached Figure Description

Detailed Implementation

[0050] To more clearly illustrate the structure and mechanism of this utility model, a preferred embodiment of this utility model will be described in detail below with reference to the accompanying drawings; however, the scope of protection of this utility model is not limited thereto.

[0051] Please refer to Figure 1A and Figure 1BAs shown, this utility model provides a floating joint measuring device, mainly comprising: a sliding device 10, a measuring tube assembly 20, and first and second connecting unit assemblies 30 and 40. The measuring tube assembly 20 is located above the sliding device 10 and is interconnected with the sliding device 10 through the first and second connecting unit assemblies 30 and 40 to achieve the function of testing the male connector C1 and female connector C2 of a quick-release connector C under skew / displacement.

[0052] Please refer to the following for further information. Figure 1A , Figure 1B and cooperate Figure 2A , Figure 2B , Figure 3A , Figure 3B and Figure 3C As shown, the sliding device 10 includes: a slide assembly 11, a fixed seat 12 and a floating joint fixed seat 17 disposed on the slide assembly 11. In this embodiment, the slide assembly 11 has two slides 111, and the fixed seat 12 and the floating joint fixed seat 17 are respectively disposed on the two slides 111.

[0053] The two slides 111 of the slide assembly 11 are mounted on a base 16. The base 16 has a linear groove 161 that allows the slides 111 to be embedded in it, facilitating precise guidance of the slides 111 on the base 16. The base 16 can be connected to an external control source (such as a power source, pneumatic source, or hydraulic source) to control the movement of the sliding device 10 by electronic drive, hydraulic or pneumatic means, so that the two slides 111 slide bidirectionally on the base 16, moving in opposite or relative directions, thereby pushing the male connector C1 of the quick-release connector C under test to engage or disengage with the female connector C2.

[0054] To test the docking / disengagement status of the female connector C2 and male connector C1 of the quick-release connector C under test, a connector 14 is provided on the fixed base 12 for connecting the female connector C2, and a floating connector fixed base 17 is provided with an obliquely arranged floating connector unit 13 for connecting the male connector C1, to simulate the docking / disengagement of the floating connector in actual applications. In this embodiment, the floating connector fixed base 17 has opposing side walls 171, and the opposing surfaces of the side walls 171 each have a mutually cooperating inclined surface 172, which are inclined in the same direction. For example... Figure 3C The display shows that the two inclined surfaces 172 tilt to the right from top to bottom, and the floating connector unit 13 is disposed at an angle between the two inclined surfaces 172. This allows the male connector C1 and female connector C2 to be connected at a relative angle or at an angle with their center lines not aligned, and to automatically correct for separation after displacement connection. However, not limited to the above, in other embodiments, the floating connector fixing seat 17 can also be fixed at an angle on the slide table 111, or the floating connector fixing seat 17 and the floating connector unit 13 can be fixed using locking elements of different lengths, both achieving the effect of an angled arrangement.

[0055] Please refer to the reply. Figure 1B , Figures 2A to 2B and 3A to Figure 3C As shown, the adapter 14 has a pipe connection portion 141 at one end and a test sample connection portion 142 at the other end for connecting to the female connector C2. In this embodiment, the test sample connection portion 142 is provided with a locking or locking structure (e.g., internal thread) for the female connector C2 to be locked or locked into. To ensure that the adapter 14 is stably positioned during testing, the mounting base 12 is provided with a groove 121 (e.g., a V-groove or an arc groove) and a window 122 located below the groove 121. The adapter 14 is placed on the groove 121 and is fixed on the outer surface of the adapter 14 by a fixing element 15 (e.g., but not limited to a metal clamp) and passes through the window 122. This allows the adapter 14 to move stably and without wobbling with the slide assembly 11. On the other hand, when it is necessary to test different sizes or types of quick-release connectors C, only the corresponding floating connector unit 13 and adapter 14 need to be replaced, and the stroke of the slide assembly 11 needs to be adjusted, so that diverse tests can be completed using the same equipment.

[0056] The aforementioned floating joint unit 13 is, for example, a generally known or applied floating joint structure. For further understanding, please refer to... Figure 4A and Figure 4B As shown, in this embodiment, for example but not limited to, the floating joint unit 13 includes: a housing 131, an adapter 132, a sliding pad 133, a fastener 134, a backing pad 135, and a spring 136.

[0057] The housing 131 has an open side 1311 and a closed side 1312. An accommodating space 1313 is located between the open side 1311 and the closed side 1312. The closed side 1312 is provided with a through hole 1314 that connects to the accommodating space 1313. The outer surface of the closed side 1312 has an elastic ring 1315 that is arranged around the outer periphery of the through hole 1314.

[0058] The adapter 132 has a connecting section 1321, a sleeve section 1322, and a channel 1324. The connecting section 1321 extends from the accommodating space 1313 toward the open side 1311 to connect the male connector C1. The sleeve section 1322 extends from the accommodating space 1313 toward the through hole 1314 on the closed side 1312 and protrudes outward from the through hole 1314. An axial abutment portion 1323 is formed between the connecting section 1321 and the sleeve section 1322. The channel 1324 is formed in the adapter 132 and extends from the connecting section 1321 to the sleeve section 1322, passing through both ends of the adapter 132.

[0059] The sliding pad 133 is sleeved onto the sleeve section 1322 of the adapter 132 from the outer surface of the closed side 1312, and one side of the sliding pad 133 is radially slidably attached to the outer surface of the closed side 1312 and contacts the elastic ring 1315.

[0060] Fastener 134 (e.g., snap ring, nut or other element) is fastened to the sleeve section 1322 of adapter 132, adjacent to the other side of the sliding pad 133, so as to axially limit adapter 132 relative to housing 131 and allow adapter 132 to move radially relative to housing 131.

[0061] The abutment pad 135 is disposed in the accommodating space 1313 and sleeved on the adapter 132. One side of the pad abuts against the inner surface of the closed side 1312, and a protrusion 1351 abuts against one side of the sliding pad 133 through the through hole 1314, so that the abutment pad 135 and the sliding pad 133 are clamped on the inner and outer surfaces of the closed side 1312 of the housing 131.

[0062] A spring 136 is disposed within the receiving space 1313 and sleeved on the outer periphery of the adapter 132. The two ends of the spring 136 abut against one side of the abutment pad 135 and the axial abutment portion 1323 of the adapter 132, respectively. This provides axial compression stroke, allowing the adapter 132 to withstand axial tolerances and minor axial tilt adjustments. Simultaneously, the spring 136's inherent elasticity provides a supporting force between the sliding pad 133 and the housing 131.

[0063] By combining the abutment shim 135, the sliding shim 133, and the spring 136, the sliding resistance between the sliding shim 133 and the housing 131 is controlled and adjusted, allowing the adapter 132 to stop at any radially offset position after radially moving relative to the housing 131. In this way, the male connector C1 mounted on the floating connector unit 13 can automatically align itself during misaligned docking, ensuring its centerline is aligned with the centerline of the female connector C2.

[0064] Please refer to the reply. Figure 1A , Figure 1B and cooperate Figure 5As shown, the measuring tube assembly 20 includes a first measuring tube 21 and a second measuring tube 22 arranged vertically apart (left and right as shown in the figure) to obtain accurate changes in the medium when measuring leakage and trapped air. The upper end of the first measuring tube 21 has a first opening 211, and the upper end of the second measuring tube 22 has a second opening 221. When testing is to be performed, depending on the test item, a test medium (e.g., liquid) can be injected into the measuring tube through the first or second opening 211, 221, and then one of the openings is closed. In some embodiments, the first and second measuring tubes 21 and 22 are the same size, and graduations are provided on their outer surfaces to measure changes in the medium inside, or a pressure / flow sensor is provided to read changes in the test medium inside.

[0065] The lower end of the first measuring tube 21 is connected to the floating connector unit 13 via the first connecting unit group 30, and the lower end of the second measuring tube 22 is connected to the adapter 14 and the first connecting unit group 30 via the second connecting unit group 40. By connecting the first and second connecting unit groups 30 and 40 in series with the first measuring tube 21, the second measuring tube 22, the floating connector unit 13, and the adapter 14, the leakage (fluid loss) or air inclusion can be measured during repeated docking of the male connector C1 and the female connector C2 with inconsistent center lines, and during the operation of separation after correcting the docking.

[0066] Specifically, the first connecting unit group 30 includes a first three-way valve 31 (e.g., a Y-type three-way valve), a first connecting pipe 32, and a second connecting pipe 33; the second connecting unit group 40 includes a second three-way valve 41 (e.g., a T-type three-way valve), a third connecting pipe 42, and a fourth connecting pipe 43. The first three-way valve 31 connects to the lower end of the first measuring pipe 21 and is connected to the floating connector unit 13 through the first connecting pipe 32, and is also connected to the second three-way valve 41 through the second connecting pipe 33. The second three-way valve 41 is connected to the lower end of the second measuring pipe 22 through the third connecting pipe 42 and is connected to the adapter 14 through the fourth connecting pipe 43.

[0067] Please refer to the following for further information. Figure 1A , Figure 1B As shown, this invention mounts the sliding device 10, the measuring tube assembly 20, and the first and second connecting unit assemblies 30 and 40 onto a fixed back plate 51 (e.g., a perforated plate) to position these components on the fixed back plate 51, preventing displacement during testing and facilitating component replacement. Additionally, a vibrator 52 is selectively mounted on the fixed back plate 51, adjacent to the first measuring tube 21. During measurement, the vibrator 52 gently vibrates the first measuring tube 21 to quickly expel air bubbles, preventing data errors caused by bubble interference.

[0068] The following explanation will use the floating joint of a liquid pipeline as an example to illustrate the measurement of air inclusion using the equipment described in this case. Please refer to... Figure 6 And in conjunction with the aforementioned Figures 1A to 5 As shown.

[0069] Step 1: Installation and preparation of the connector to be tested

[0070] like Figure 2B As shown, the male connector C1 and female connector C2 of the quick-release connector C to be tested are first installed on the joint section 1321 of the floating connector unit 13 and the test connection part 142 of the adapter 14, respectively, with the male connector C1 and female connector C2 at a relative angle or relative tilt that are not aligned with their center lines. In this embodiment, the tilt angle of the male connector C1 relative to the female connector C2 is, for example, but not limited to, 1.5 degrees. Then, as... Figure 3A As shown, male connector C1 and female connector C2 are kept in a mated state beforehand to facilitate subsequent water injection, air venting, and marking of water level. This prevents subsequent test results from being affected by changes in the designed medium volume due to the separation or mating state of male connector C1 and female connector C2.

[0071] like Figure 1A , Figure 1B , Figure 3A , Figure 4A , Figure 4B , Figure 5 and Figure 6 As shown, when the male connector C1 and female connector C2 are connected, a medium (e.g., water) is injected into the second measuring tube 22 on the right through the second opening 221, filling the first and second connecting unit groups 30 and 40 with the medium until the water levels in the first and second measuring tubes 21 and 22 reach the same predetermined height (e.g., 2 / 3 of the height of the first and second measuring tubes 21 and 22). Water injection is then stopped, and the water level positions in the first and second measuring tubes 21 and 22 are marked. If a vibrator 52 is selected, it can be activated simultaneously with the injection of the medium to help remove air bubbles and ensure that there are no air bubbles below the water surface.

[0072] Step 2: Seal

[0073] Use a sealing element (such as tape) to seal the first opening 211 at the top of the first measuring tube 21 on the left to ensure controlled flow of the medium.

[0074] Step 3: Perform disconnection / docking

[0075] The operator can control the sliding device 10 via an external control switch using pneumatic, electrical, or hydraulic methods. Figure 3A , Figure 3B , Figure 3C and Figure 6It can be seen that the two slides 111 of the slide assembly 11 slide in opposite directions on the base 16, so that the floating joint unit 13 and the adapter 14 gradually separate from the docking state, and complete the separation action of the male head C1 and the female head C2.

[0076] After the male connector C1 and the female connector C2 separate, the control slide assembly 11 moves in reverse, causing the two slides 111 to slide linearly in opposite directions on the base 16. This causes the floating connector unit 13 and the adapter 14 to gradually move closer from their separated state, allowing the male connector C1 and the female connector C2 to align at a relative angle or with their center lines not aligned. Furthermore, the floating connector unit 13 automatically corrects the relative angle or skew when the male connector C1 aligns with the female connector C2, ensuring that the center lines of the male connector C1 and the female connector C2 are aligned after alignment.

[0077] During the separation / docking process, the gas emission path in the pipeline is from the first connecting pipe 32 through the first three-way valve 31 to the first measuring pipe 21 on the left. During the docking test, if any air bubbles remain below the water surface, the vibrator 52 can be activated to move the air bubbles to the water surface of the first measuring pipe 21 on the left.

[0078] Step 4: Repeated separation / docking:

[0079] Repeat step 3 above, connecting male connector C1 and female connector C2 at a relative angle or with their center lines not aligned, and then separating them after automatic alignment. Repeat this separation / connection test until the water level inside the first measuring tube 21 on the left drops to the target mark (e.g., a drop of 10 marks). Stop the test, keeping male connector C1 and female connector C2 in the connected state, and record the number of connections to calculate the average air trapping volume.

[0080] The following explanation uses the floating joint of the liquid pipeline as an example to illustrate the measurement of fluid loss using the equipment in this case. Please refer to the same diagram; this test is largely the same as the aforementioned air trapping measurement, with the following differences:

[0081] Step 2: Seal

[0082] Use a sealing element (such as tape) to seal the second opening 221 at the top of the second measuring tube 22 on the right to ensure controlled media flow.

[0083] Step 4: Repeated separation / docking

[0084] Repeat step 3 above, performing the separation action after the male connector C1 and female connector C2 are automatically corrected by connecting them at a relative angle or with a slight deviation from their center lines. Repeat this separation / connection test until the water level inside the first measuring tube 21 on the left drops to the target scale (e.g., a drop of 10 scales). Stop the test after maintaining the male connector C1 and female connector C2 in the connected state, and record the number of connections to calculate the average separation leakage.

[0085] In summary, this utility model has the following advantages and effects:

[0086] 1. One machine, multiple tests: Using the same equipment, the male head C1 and female head C2 of the quick-release connector C under test are simulated to be connected in a skewed (biased) state with their center lines not aligned, and to be separated after automatic correction of displacement connection. This corresponds to the connection / separation of floating connectors in actual applications. By simply switching the position of the first opening 211 or the second opening 221 of the first and second measuring tubes 21, two different tests, namely separation leakage and trapped air volume, can be completed. This is operable and feasible, and can save on testing costs.

[0087] 2. Simple and stable testing operation: The sliding device 10 is used to achieve stable advancement of the male head C1 and the female head C2 during docking / separation, reducing the impact of test errors caused by uneven human force application, resulting in high test result stability and shortening test time.
