Description

Technical Field

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

[0002] With the continuous improvement of the computing performance of servers, the heat generated during system operation also increases rapidly. The application of traditional air-cooling solutions in high-heat-density servers gradually fails to meet the requirements. As the current main 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 requirements on the pressure resistance and sealing of 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 and pose 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 the maintenance cost.

[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. Coolant leakage 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 itself. Therefore, reducing the possibility of quick-release joint failure and ensuring controllable risks during replacement or disassembly and assembly become important topics 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 the application requirements of servers.

[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-release joint 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-release joint.

[0011] Although ISO 18869 provides the basic theory and device schematic for testing the leakage and air entrainment of quick-release joints, 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 operators relying on traditional testing methods and simple devices. However, these methods and devices have the following defects:

[0012] 1. Instability in the testing process: Most traditional devices are manually operated, lacking precise control over the butting and separating actions, and the data is prone to deviation due to human operation.

[0013] 2. Limitations in the equipment structure: Existing testing devices are usually only applicable to quick-release joints of a single size or type, lacking universality, and unable to accurately test the separation leakage and air entrainment at the same time.

[0014] 3. Insufficient data accuracy: The influence of bubble interference during the testing process is not fully considered, resulting in deviation of the air entrainment data.

[0015] Therefore, there is an urgent need in the existing technology for a device that can simultaneously test the separation leakage and air entrainment to solve the above technical defects and improve the accuracy and reliability of the testing. Summary of the Invention

[0016] The purpose of the present invention is to provide a measuring device for quick-release joints that can solve the above problems. This device is applicable to a variety of quick-release joints for two testing operations of leakage and air entrainment to solve the defects and challenges in the existing technology.

[0017] To achieve the above purpose, the present invention provides a measuring device for quick-release joints, which is characterized in that it includes:

[0023] The first connection unit set includes a first three-way valve, a first connecting tube and a second connecting tube;

[0024] The second connection unit set includes a second three-way valve, a third connecting tube and a fourth connecting tube.

[0025] In the quick-release joint measuring device described above:

[0026] The first three-way valve is connected to the lower end of the first measuring tube, and is connected to the first adapter through the first connecting tube and to the second three-way valve through the second connecting tube;

[0027] The second three-way valve is connected to the lower end of the second measuring tube through the third connecting tube and to the second adapter through the fourth connecting tube.

[0028] In the quick-release joint measuring device described above: The sliding device, the first measuring tube, the second measuring tube, and the first connection unit set and the second connection unit set are fixed on a fixing unit.

[0029] In the quick-release joint measuring device described above: A vibrator is arranged on the fixing unit to eliminate bubble interference during the test.

[0030] By the above technical solutions, the present invention achieves the following technical effects:

[0031] 1. Diversity and versatility of test functions: The device can simultaneously support the separation leakage test and the trapped air volume test of the quick-release joint, and is applicable to quick-release joints of different sizes and types.

Detailed Description of the Preferred Embodiments

[0044] To more clearly illustrate the structure and working mechanism of the present invention, the following will describe the preferred embodiments of the present invention in detail with reference to the accompanying drawings; however, the protection scope of the present invention is not limited thereto.

[0045] Please refer to Figure 1A and Figure 1B As shown, the present invention provides a quick-release joint measuring device, mainly including: a sliding device 10, a measuring pipe group 20, and first and second communication unit groups 30, 40. The measuring pipe group 20 is located above the sliding device 10 and is communicated with the sliding device 10 through the first and second communication unit groups 30, 40.

[0046] Continuing to refer to Figure 1A , Figure 1B , and in cooperation with Figure 2A , Figure 2B , Figure 3A and Figure 3B As shown, the sliding device 10 (such as a sliding device driven by air pressure or hydraulic pressure or electric control), includes a slide table group 11 and two fixed seats 12 arranged on the slide table group 11. First adapters 13 and second adapters 14 are respectively provided on the fixed seats 12 for corresponding to the male head c1 and female head c2 of a quick-release joint c to be tested. The slide table group 11 is arranged on a base 16, and the base 16 is provided with a linear chute 161 to cooperate with the slide table group 11 to guide the linear bidirectional sliding of the slide table group 11. The base 16 is connected to an external control source (such as a power switch or an air pressure source switch or a hydraulic switch, not shown) to drive the operation of the slide table group 11 electrically or hydraulically or pneumatically. In this embodiment, it is shown that the slide table group 11 has two slide tables 111 that can slide linearly in both directions, and the fixed seats 12 are respectively arranged on the two slide tables 111.

[0047] One end of each of the first adapter 13 and the second adapter 14 is provided with a pipe connection portion 131, 141 for connecting the first and second communication unit groups 30, 40, and the other end is provided with a test piece connection portion 132, 142 for connecting the male head c1 and the female head c2 of the quick-release joint c to be tested respectively. In this embodiment, the test piece connection portions 132, 142 are provided with locking or clamping structures (such as internal threads, etc.) for the male and female heads c1, c2 of the quick-release joint c to be locked or clamped therein. To ensure the stable positioning of the first adapter 13 and the second 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 first adapter 13 and the second adapter 14 are placed on the groove 121, and a fixing element 15 (such as but not limited to a metal band) is arranged on the outer surfaces of the first adapter 13 and the second adapter 14 and passes through the window 122 for fixing. Thereby, the first adapter 13 and the second adapter 14 can stably move along with the slide group 11 without shaking, and drive the male head c1 and the female head c2 of the quick-release joint c to move towards each other for docking or move in the opposite direction for separation. On the other hand, if a large number of quick-release joints of different sizes or different types need to be tested, only the corresponding first adapter 13 and the second adapter 14 need to be replaced, and the stroke of the slide group 11 is adjusted, then the same device can be used to complete diversified tests.

[0048] Please refer to again Figure 1A 、 Figure 1B And cooperate with Figure 4 As shown, the measuring tube group 20 includes a first measuring tube 21 and a second measuring tube 22 which are vertically and separately arranged (separated left and right in the figure), so as to obtain an accurate change amount of the medium when measuring the separation leakage amount and the trapped gas amount. The upper end of the first measuring tube 21 is provided with a first opening 211, and the upper end of the second measuring tube 22 is provided with a second opening 221. When a test is to be carried out, according to different test items, a test medium (such as a liquid) can be injected into the measuring tube through the first opening 211 or the second opening 221, and then one of the openings is closed. In some embodiments, the first measuring tube 21 and the second measuring tube 22 have the same size, and scales are provided on their outer surfaces for measuring the change of the medium therein, or pressure / flow sensors are provided to read the change of the test medium therein.

[0049] The lower end of the first measuring tube 21 is communicated with the first adapter 13 through the first communication unit group 30, and the lower end of the second measuring tube 22 is communicated with the second adapter 14 and the first communication unit group 30 through the second communication unit group 40. Through the mutual connection of the first and second communication unit groups 30, 40, the first measuring tube 21, the second measuring tube 22, the first adapter 13, and the second adapter 14, the separation leakage amount or the trapped gas amount of the quick-release joint c to be tested can be measured during the repeated docking and separation operations of the quick-release joint c to be tested.

[0050] Specifically, the first connection unit group 30 includes a first three-way valve 31 (such as a Y-shaped three-way valve), a first connecting pipe 32, and a second connecting pipe 33; the second connection unit group 40 includes a second three-way valve 41 (such as a T-shaped three-way valve), a third connecting pipe 42, and a fourth connecting pipe 43. The first three-way valve 31 is connected to the lower end of the first measuring pipe 21, and is connected to the first adapter 13 through the first connecting pipe 32, and is also communicated with the second three-way valve 41 through the second connecting pipe 33. The second three-way valve 41 is communicated to the lower end of the second measuring pipe 22 through the third connecting pipe 42, and is connected to the second adapter 14 through the fourth connecting pipe 43.

[0051] Please continue to refer to Figure 1A 、 Figure 1B As shown, the present invention disposes the sliding device, the measuring pipe group, and the first and second connection unit groups on a fixed unit 51 such as a fixed wall, a back plate, or a perforated plate, so as to position these components on the fixed unit 51 and prevent them from shifting during the test. In addition, a vibrator 52 is selectively disposed on the fixed unit 51. The vibrator 52 is adjacent to the first measuring pipe 21 and is used to slightly vibrate the first measuring pipe 21 during the measurement process to prompt the bubbles therein to be quickly removed and avoid data errors caused by bubble interference.

[0052] The following will take the application of the quick-release joint of the liquid pipeline to the equipment of the present invention for measuring the trapped air volume as an example for illustration. Please refer to Figure 1A 、 Figure 1B 、 Figure 2A 、 Figure 2B 、 Figure 3A 、 Figure 3B 、 Figure 4 and Figure 5 shown.

[0053] Step 1: Installation and preparation of the quick-release joint C to be tested

[0054] As Figure 2B shown, the male head c1 and the female head c2 of the quick-release joint c to be tested can be respectively installed on the test product connection parts 132 and 142 of the first adapter 13 and the second adapter 14, and it is ensured that the male head c1 and the female head c2 are firmly fixed on the groove 121 of the fixed seat 12. 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, the subsequent test results are prevented from being affected by the change in the medium volume design value of the separation and docking states of the male head c1 and the female head c2.

[0055] As Figure 1A 、 Figure 1B 、 Figure 3A 、 Figure 4 andFigure 5 As shown, when the male connector c1 and the female connector c2 are in the docked 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 and 40 are filled with the medium until the water surfaces in the first measuring tube 21 and the second measuring tube 22 reach a predetermined same height position (for example, reach the 2 / 3 height position of the first measuring tube 21 and the second measuring tube 22). Stop injecting water and mark the height positions of the water surfaces in the first measuring tube 21 and the second measuring tube 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.

[0056] Step 2: Sealing

[0057] 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.

[0058] Step 3: Perform separation / docking

[0059] The operator can control the operation of the sliding device 10 in a pneumatic, electro-controlled or hydraulic manner through an external control switch. As Figure 3A , Figure 3B and Figure 5 show, the two sliding platforms 111 of the sliding platform group 11 slide linearly in opposite directions on the base 16, so that the first adapter 13 and the second adapter 14 are gradually separated from the docked state, completing the separation action of the male connector c1 and the female connector c2.

[0060] After the male connector c1 and the female connector c2 are separated, control the reverse movement of the sliding platform group 11, so that the two sliding platforms 111 slide linearly in opposite directions on the base 16, so that the first adapter 13 and the second adapter 14 gradually approach from the separated state, completing the docking action of the male connector c1 and the female connector c2. During the separation / docking process, the gas discharge path in the pipeline is from the first communication pipe 32 through the first three-way valve 31 to the first measuring tube 21 on the left. During the docking test process, if there are air bubbles staying under the water surface, the vibrator 52 can be started to move the air bubbles to the water surface of the first measuring tube 21 on the left.

[0061] Step 4: Repeat separation / docking:

[0062] Repeat the separation / docking action of the male connector c1 and the female connector c2 in step 3. Repeatedly operate the separation / docking test in this way until the internal medium water surface in the first measuring tube 21 on the left drops to the target scale (for example, 10 scales). Keep the male connector c1 and the female connector c2 in the docked state and then stop the test, record the number of dockings to calculate the average trapped gas volume.

[0063] The following will take the quick-release joint of the liquid pipeline as an example to measure the separation leakage using the device of the present invention. Please refer to the same figure. This test is roughly the same as the above-mentioned trapped gas measurement, and the difference is:

[0064] Step 2: Seal

[0065] A sealing element (such as adhesive tape) is used to seal the second opening 221 at the top of the second right measuring tube 22 to ensure that the medium flow is controlled.

[0066] Step 4: Repeat the separation / docking:

[0067] Repeat the separation / docking action of the male connector c1 and the female connector c2 in step 3. Repeat the separation / docking test until the water level of the medium in the first measuring tube 21 on the left side drops to the target scale (e.g., 10 scales). After the male connector c1 and the female connector c2 are kept in the docking state, stop the test and record the number of docking times to calculate the average separation leakage.

[0068] Thus, the advantages of performing the above two measurements by the device of the present invention are:

[0069] 1. The detection operation is convenient.

[0070] 2. The test process is less affected by human factors and the test results are highly stable.

[0071] 3. The same device can be used to perform two test items: separation leakage and trapped gas volume. Different tests can be completed through simple operation switching, saving test costs.

[0072] 4. It should be operational and feasible.

[0073] In summary, the present invention provides precise control of the connection / separation of the quick-release connector by means of the sliding device 10, and can be applied to quick-release connectors of various types and sizes by only replacing or adjusting the corresponding first adapter 13 and second adapter 14. And through the measuring tube set 20 and the first and second connecting unit sets 30 and 40, the operator can accurately and conveniently measure the two important parameters of separation leakage and trapped gas volume. In addition, the optional vibrator 52 helps to remove bubbles, which effectively improves the reliability of the measurement data.

[0074] 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 concept 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 quick-release joint measurement device is provided.
