Description

Technical Field

[0001] The present invention relates to the field of measurement of quick-release joints, and particularly to a measuring device for the separation leakage amount and air entrapment amount of a floating joint. Background Art

[0002] With the continuous improvement of the computing performance of servers, the heat generated during system operation has also increased rapidly. The application of traditional air-cooling solutions in high-heat-density servers gradually fails to meet the requirements. As the main current solution, liquid-cooling technology provides more efficient heat transfer and heat dissipation capabilities. However, the existing liquid-cooling architectures still have the following types and challenges:

[0003] 1. Water-to-air architecture: mainly used for the retrofit of existing air-cooled computer rooms. By installing backdoor fans and water-cooling pipelines, the retrofit threshold is reduced. However, this solution generates high noise during operation and is difficult to provide a long-term solution.

[0004] 2. Water-to-water architecture: places higher pressure resistance and sealing requirements on the coolant pipelines and joints. Taking the closed-loop water-to-water solution adopted by high-end NVIDIA chips as an example, any minor leakage may lead to system failure, bringing significant risks.

[0005] 3. Immersion cooling architecture: Although regarded as a potential technology for the future, it requires re-planning the computer room structure, carefully selecting dielectric fluids, and its application scenarios are more complex, especially with many challenges in the use of joints.

[0006] Liquid-cooling system architectures usually require laying coolant pipelines inside servers or between cabinets. To facilitate maintenance, quick assembly, or module replacement, quick-release joints become one of the key components. However, if quick-release joints leak or are inconvenient to disassemble and assemble, it will have a great impact on the reliability of the system and maintenance costs.

[0007] Compared with traditional hydraulic systems or ordinary water-cooling solutions, AI servers have more stringent requirements for the sealing performance of quick-release joints. The leakage of coolant may cause short circuits or damage to sensitive electronic components, and the economic losses caused by server downtime for maintenance often far exceed the cost of the joint body. Therefore, reducing the possibility of quick-release joint failure and ensuring controllable risks during replacement or disassembly and assembly become important issues in liquid-cooling system design. At the same time, the reliability testing of quick-release joints is becoming increasingly important in the context of meeting server application requirements.

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

[0009] 1. Fluid Loss Test: It is to test the average medium leakage after the plug and socket of the quick coupling are separated from the butted state.

[0010] 2. Air Inclusion Test: It is to test the amount of air introduced into the medium circuit during the butting operation of the quick coupling.

[0011] One of the application products of the quick coupling is the floating coupling. In addition to providing the butting function of the quick coupling, the floating coupling additionally adds the function of automatically correcting skewness and displacement during butting. However, one of the reliability test items for the floating coupling is to measure the fluid loss and air inclusion under simulated skewed and displaced states.

[0012] Although ISO 18869 provides the basic theory and device schematic for measuring the leakage and air entrainment of quick couplings, the specific details of the measuring equipment and key components are still not perfect. At the same time, there is no publicly available and specific dedicated measuring equipment on the market, resulting in industry players relying on traditional test methods and simple devices. However, these methods and devices have the following defects:

[0013] 1. Instability during the test process: Most traditional devices are manually operated, and the butting and separating actions lack precise control, and the data is easily affected by human operation and deviated.

[0014] 2. Limitations of the device structure: Existing test devices are usually only applicable to quick couplings of a single size or type, lacking universality, and unable to accurately test both fluid loss and air inclusion at the same time, nor can they be applied to the test of floating couplings.

[0015] 3. Insufficient data accuracy: The influence of bubble interference during the test process is not fully considered, resulting in deviation of the air inclusion data.

[0016] Therefore, there is an urgent need in the prior art for a device that can solve the above technical defects and improve the accuracy and reliability of the test. Summary of the Invention

[0017] The purpose of the present invention is to provide a measuring device for floating couplings that can solve the above problems. This device is suitable for simulating the floating coupling to perform two test operations of fluid loss and air inclusion in skewed and displaced states to solve the defects and challenges in the prior art.

[0018] To achieve the above purpose, the present invention provides a measuring device for floating couplings, which is characterized by comprising:

Detailed implementation manners

[0050] To make the structure and action mechanism of the present invention more clear, the following will describe a preferred embodiment of the present invention in detail with reference to the accompanying drawings; however, the protection scope of the present invention is not limited thereto.

[0051] Please refer to Figure 1A and Figure 1BAs shown in the figure, the present invention provides a floating joint measuring device, mainly including: a sliding device 10, a measuring pipe group 20, and first and second communication unit groups 30, 40. Among them, the measuring pipe group 20 is located above the sliding device 10 and is interconnected with the sliding device 10 through the first and second communication unit groups 30, 40 to achieve the test function of the male head C1 and the female head C2 of a tested quick-release joint C in a skewed / displaced state.

[0052] Please continue to refer to Figure 1A 、 Figure 1B and cooperate with Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 3B and Figure 3C As shown in the figure, the sliding device 10 includes: a slide table group 11, a fixed seat 12 and a floating joint fixed seat 17 arranged on the slide table group 11. In this embodiment, it is shown that the slide table group 11 has two slide tables 111, and the fixed seat 12 and the floating joint fixed seat 17 are respectively arranged on the two slide tables 111.

[0053] The two slide tables 111 of the slide table group 11 are arranged on a base 16. The base 16 is provided with a linear chute 161 for the slide table 111 to be embedded therein, so as to accurately guide the movement of the slide table 111 on the base 16. The base 16 can be connected to an external control source (such as a power source, a pneumatic source or a hydraulic source) to control the movement of the sliding device 10 in an electric drive or hydraulic or pneumatic manner, so that the two slide tables 111 make a two-way linear slide on the base 16, moving in opposite or reverse directions respectively, and then pushing the male head C1 and the female head C2 of the tested quick-release joint C to dock or separate.

[0054] In order to test the state of the female head C2 and the male head C1 of the tested quick-release joint C during docking / separation, a adapter 14 is provided on the fixed seat 12 for connecting the female head C2, and the floating joint fixed seat 17 is provided with a floating joint unit 13 arranged obliquely for connecting the male head C1 to simulate the docking / separation of the floating joint in actual application. In this embodiment, the floating joint fixed seat 17 has opposite side walls 171, and the opposite surfaces of the two side walls 171 respectively have a pair of inclined surfaces 172 that cooperate with each other, and the inclined surfaces 172 incline in the same direction. For example Figure 3C shows that the two inclined surfaces 172 incline to the right from top to bottom, and the floating joint unit 13 is arranged obliquely between the two inclined surfaces 172. Thereby, the relative angle or relative skew docking of the male head C1 and the female head C2 with inconsistent center lines is operated, and the separation after the displacement docking is automatically corrected. However, it is not limited to the above. In some other embodiments, the floating joint fixed seat 17 can also be fixed obliquely on the slide table 111, or the floating joint fixed seat 17 and the floating joint unit 13 are fixed by locking elements with different lengths, and the oblique setting effect can be achieved.

[0055] Please refer to again Figure 1B 、 Figures 2A to 2B and 3A to Figure 3C As shown, one end of the adapter 14 is provided with a pipe connection portion 141, and the other end is provided with a test piece connection portion 142 for connecting the female head C2. In this embodiment, the test piece connection portion 142 is provided with a locking or clamping structure (such as an internal thread, etc.) for the female head C2 to be locked or clamped therein. To ensure the stable positioning of the adapter 14 during the test, a groove 121 (such as a V-shaped groove or an arc-shaped groove) and a window 122 located below the groove 121 are provided on the fixed seat 12. The adapter 14 is placed on the groove 121 and is fixed by a fixing element 15 (such as, but not limited to, a metal tie strap) on the outer surface of the adapter 14 and passing through the window 122. Thereby, the adapter 14 can move stably without shaking along with the slide table group 11. On the other hand, in the case of needing to test different sizes or different types of the tested quick-release connector C, only the corresponding floating joint unit 13 and the adapter 14 need to be replaced, and the stroke of the slide table group 11 is adjusted, and the same device can be used to complete diversified tests.

[0056] The above-mentioned floating joint unit 13 is, for example, a generally known or applied-for floating joint structure. For the sake of 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 seat 131, an adapter 132, a sliding gasket 133, a fastener 134, a abutting gasket 135, and a spring 136.

[0057] The housing seat 131 has an open side 1311 and a closed side 1312. An accommodation 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 communicating with the accommodation space 1313. The outer surface of the closed side 1312 has an elastic ring 1315 provided around the outer circumference of the through hole 1314.

[0058] The adapter 132 has an engaging section 1321, a socket section 1322, and a channel 1324. The engaging section 1321 extends from within the accommodation space 1313 toward the open side 1311 for connecting the male head C1. The socket section 1322 extends from the accommodation space 1313 toward the through hole 1314 on the closed side 1312 and protrudes outward from the through hole 1314. An axial abutting portion 1323 is formed between the engaging section 1321 and the socket section 1322. The channel 1324 is formed within the adapter 132 and extends from the engaging section 1321 to the socket section 1322 and penetrates through both ends of the adapter 132.

[0059] The sliding gasket 133 is sleeved on the socket section 1322 of the adapter 132 from the outer surface of the closed side 1312, and one side of the sliding gasket 133 is slidably abutted against the outer surface of the closed side 1312 and contacts the elastic ring 1315.

[0060] The fastener 134 (such as a snap ring or a nut or other components) is fastened to the socket section 1322 of the adapter 132 and abuts against the other side of the sliding gasket 133 adjacent thereto, for axially limiting the adapter 132 relative to the housing 131 and enabling the adapter 132 to move radially relative to the housing 131.

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

[0062] The spring 136 is disposed in the accommodating space 1313 and sleeved on the outer periphery of the adapter 132. The two ends of the spring 136 respectively abut against one side of the abutting gasket 135 and the axial abutting portion 1323 of the adapter 132. Thereby, an axial compression stroke is provided, so that the adapter 132 can withstand axial tolerances and axial fine-tuning tilts. At the same time, due to the elastic characteristic of the spring 136 itself, a positive force for supporting between the sliding gasket 133 and the housing 131 is provided.

[0063] By the combination of the abutting gasket 135, the sliding gasket 133 and the spring 136, the sliding resistance between the sliding gasket 133 and the housing 131 is controlled and adjusted, and after the adapter 132 moves radially relative to the housing 131, it can stop at any position of the radial offset. Thereby, the male head C1 mounted on the floating joint unit 13 can be automatically aligned during skew docking, so that its center line is aligned with the center line of the female head C2.

[0064] Please refer back to Figure 1A 、 Figure 1B And in cooperation with Figure 5As shown, the measurement tube group 20 includes a first measurement tube 21 and a second measurement tube 22 that are vertically and separately arranged (as shown separated left and right in the figure) so as to obtain an accurate change in the medium when measuring the leakage volume and the trapped gas volume. The upper end of the first measurement tube 21 is provided with a first opening 211, and the upper end of the second measurement tube 22 is provided with a second opening 221. When a test is to be performed, according to different test items, a test medium (such as a liquid) can be injected into the measurement tube through the first or second opening 211, 221, and then one of the openings is sealed. In some embodiments, the first and second measurement tubes 21, 22 have the same dimensions, and scales are provided on their outer surfaces to measure the change in the medium therein, or pressure / flow sensors are provided to read the change in the test medium therein.

[0065] The lower end of the first measurement tube 21 is connected to the floating joint unit 13 via the first communication unit group 30, and the lower end of the second measurement tube 22 is connected to the adapter 14 and the first communication unit group 30 via the second communication unit group 40. Through the mutual connection of the first and second communication unit groups 30, 40 with the first measurement tube 21, the second measurement tube 22, the floating joint unit 13, and the adapter 14, the fluid loss or air inclusion can be measured during the repeated docking process in which the male head C1 and the female head C2 are not aligned in the center line and the operation of separating after the alignment docking.

[0066] Specifically, the first communication unit group 30 includes a first three-way valve 31 (such as a Y-shaped three-way valve), a first communication pipe 32, and a second communication pipe 33; the second communication unit group 40 includes a second three-way valve 41 (such as a T-shaped three-way valve), a third communication pipe 42, and a fourth communication pipe 43. The first three-way valve 31 communicates with the lower end of the first measurement tube 21, is connected to the floating joint unit 13 through the first communication pipe 32, and also communicates with the second three-way valve 41 via the second communication pipe 33. The second three-way valve 41 is then connected to the lower end of the second measurement tube 22 via the third communication pipe 42 and is connected to the adapter 14 through the fourth communication pipe 43.

[0067] Continue to refer to Figure 1A 、 Figure 1B As shown, in the present invention, the sliding device 10, the measurement tube group 20, and the first and second communication unit groups 30, 40 are all arranged on a fixed back plate 51 (such as a perforated plate) so as to position these components on the fixed back plate 51 to avoid displacement during the test and also facilitate the replacement of these components. In addition, a vibrator 52 is selectively arranged on the fixed back plate 51, and the vibrator 52 is adjacent to the first measurement tube 21. During the measurement process, the first measurement tube 21 is slightly vibrated by the vibrator 52 to prompt the bubbles therein to be quickly removed, avoiding data errors caused by bubble interference.

[0068] The following will take the application of the floating joint of the liquid pipeline to the equipment of this case for air inclusion measurement as an example for illustration. Please refer to Figure 6 and in conjunction with the foregoing Figures 1A to 5 as shown.

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

[0070] As Figure 2B shown, first, the male head C1 and the female head C2 of the quick-release joint C to be tested are respectively installed on the joint section 1321 of the floating joint unit 13 and the test product connection part 142 of the adapter 14, and the male head C1 and the female head C2 are at a relative angle or relative skew with inconsistent center lines. In this embodiment, the skew angle of the male head C1 relative to the female head C2 is, for example but not limited to, 1.5 degrees. Then, as Figure 3A shown, the male head C1 and the female head C2 are pre-maintained in the docking state for subsequent water injection, air exhaust, and marking the water surface height position. Thereby, preventing the subsequent test results from being affected by the change in the designed medium volume of the separation and docking states of the male head C1 and the female head C2.

[0071] As Figure 1A , Figure 1B , Figure 3A , Figure 4A , Figure 4B , Figure 5 and Figure 6 shown, when the male head C1 and the female head C2 are in the docking state, a medium (such as water) is injected into the second measuring tube 22 on the right through the second opening 221, so that the first and second communication unit groups 30, 40 are filled with the medium until the water surfaces in the first and second measuring tubes 21, 22 reach a predetermined same height position (such as reaching the 2 / 3 height position of the first and second measuring tubes 21, 22), stop water injection and mark the water surface height positions in the first and second measuring tubes 21, 22. If the vibrator 52 is selected and configured, the vibrator 52 can be started while injecting the medium to assist in removing air bubbles and ensure that there are no air bubbles under the water surface.

[0072] Step 2: Sealing

[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 medium flow.

[0074] Step 3: Perform separation / docking

[0075] The operator can control the operation of the sliding device 10 pneumatically, electrically controlled, or hydraulically by means of an external control switch. From Figure 3A , Figure 3B , Figure 3C and Figure 6It can be seen that the two sliders 111 of the slider group 11 slide linearly in opposite directions on the base 16, gradually separating the floating joint unit 13 and the adapter 14 from the docking state, and completing the separation action of the male head C1 and the female head C2.

[0076] After the male head C1 and the female head C2 are separated, control the reverse action of the slider group 11, so that the two sliders 111 slide linearly in opposite directions on the base 16, gradually displacing and approaching the floating joint unit 13 and the adapter 14 from the separated state, and making the male head C1 and the female head C2 dock at a relative angle or relative skew with inconsistent centerlines. And when the male head C1 is docked with the female head C2 through the floating joint unit 13, automatically correct its relative angle or relative skew state, so that the centerlines of the male head C1 and the female head C2 are consistent after docking.

[0077] During the separation / docking process, the gas discharge path in the pipeline is from the first connecting pipe 32 through the first three-way valve 31 to the left first measuring pipe 21. During the docking test process, if there are bubbles staying underwater, the vibrator 52 can be activated to move the bubbles to the water surface of the left first measuring pipe 21.

[0078] Step 4: Repeat separation / docking:

[0079] Repeat the above step 3 to dock the male head C1 and the female head C2 at a relative angle or relative skew with inconsistent centerlines, and the separation action after automatic correction of the displacement docking. Repeat the separation / docking test in this way, and continue docking until the water surface position of the internal medium in the left first measuring pipe 21 drops to the target scale (for example, drops 10 scales). Stop the test, keep the male head C1 and the female head C2 in the docking state and then stop the test, and record the number of dockings to calculate the average trapped gas volume.

[0080] The following takes the application of the floating joint of the liquid pipeline to measure the separation leakage amount (Fluid Loss) of the equipment in this case as an example for explanation. Please refer to the same figure. This test is generally the same as the above trapped gas volume measurement, and the differences are as follows:

[0081] Step 2: Seal

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

[0083] Step 4: Repeat separation / docking

[0084] Repeat the above step 3 to perform the separation action after the male connector C1 and the female connector C2 are connected at a relative angle or relative skewness with inconsistent center lines and the displacement connection is automatically corrected. Repeat the separation / connection test in this way, and continue to connect the first measuring tube 21 on the left until the water level of the internal medium drops to the target scale (for example, 10 scales). After the male connector C1 and the female connector C2 are kept in the connection state, stop the test and record the connection times to calculate the average separation leakage.

[0085] In summary, the present invention has the following advantages and effects:

[0086] 1. One machine for multiple tests: Use the same device to simulate the docking of the male head C1 and the female head C2 of the tested quick-release connector C in a skewed (biased) state with inconsistent center lines, and the separation after displacement docking and automatic correction, which corresponds to the docking / separation of floating connectors in actual applications; and through simple operation to switch the position of the first opening 211 or the second opening 221 of the first and second measuring tubes 21, two different tests of separation leakage and trapped gas can be completed, which is operable and achievable, and can save testing costs.

[0087] 2. The detection operation is simple and stable: the sliding device 10 is used to achieve stable advancement of the male connector C1 and the female connector C2 during docking / separation, reducing the impact of test errors caused by uneven human force, and the test results are highly stable, shortening the test time.

[0088] 3. Supporting multiple types of floating joints: Only by replacing the corresponding floating joint unit 13 or adapter 14, different types and sizes of quick-release joints can be tested.

[0089] 4. The parts are simple in design and easy to assemble and replace: a fixed back plate 51 such as a perforated plate is used to facilitate replacement of the components fixed on the fixed back plate 51.

[0090] The above are all detailed descriptions of the preferred embodiments of the present invention. Equivalent or similar modifications made according to the teachings disclosed by the present invention are naturally included in the protection scope of the present invention. Through the technical conception and combination of the present invention, not only the problems of unstable testing and inaccurate data faced by the prior art are solved, but also a highly efficient, multifunctional and economical floating joint measurement device is provided.
