Description

Technical Field

[0001] This utility model relates to a measuring device for quick-release couplings, and particularly to a measuring device for the separation leakage and trapped air volume of quick-release couplings. 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] Although ISO 18869 provides basic theory and apparatus illustrations for testing the leakage and air carryover of 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:

[0012] 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.

[0013] 2. Limitations of equipment structure: Existing testing devices are usually only applicable to quick-release connectors of a single size or type, lacking versatility, and cannot simultaneously achieve accurate testing of leakage and trapped air volume.

[0014] 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.

[0015] Therefore, there is an urgent need for a device that can simultaneously test the leakage and trapped air volumes to address the aforementioned technical deficiencies and improve the accuracy and reliability of the tests. Utility Model Content

Detailed Implementation

[0044] To further clarify the structure and mechanism of action of this utility model, the preferred embodiments 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.

[0045] Please refer to Figure 1A and Figure 1B As shown, this utility model provides a quick-release connector measuring device, which mainly includes: a sliding device 10, a measuring tube group 20, and first and second connecting unit groups 30 and 40. The measuring tube group 20 is located above the sliding device 10 and is connected to the sliding device 10 through the first and second connecting unit groups 30 and 40.

[0046] Please refer to the following: Figure 1A , Figure 1B and cooperate Figure 2A , Figure 2B , Figure 3A and Figure 3B As shown, the sliding device 10 (e.g., a pneumatic, hydraulic, or electrically driven sliding device) includes a slide assembly 11 and two fixed seats 12 disposed on the slide assembly 11. The fixed seats 12 are respectively provided with a first adapter 13 and a second adapter 14, corresponding to the male connector c1 and female connector c2 of a quick-release connector c under test. The slide assembly 11 is disposed on a base 16, which has a linear groove 161 that engages with the slide assembly 11 to guide the slide assembly 11 to slide linearly in both directions. The base 16 is connected to an external control source (e.g., a power switch, a pneumatic power source switch, or a hydraulic switch, not shown) to drive the slide assembly 11 electrically, hydraulically, or pneumatically. In this embodiment, the slide assembly 11 has two slides 111 that can slide linearly in both directions, and the fixed seats 12 are disposed on the two slides 111.

[0047] Each of the first adapter 13 and the second adapter 14 has a pipe connection portion 131, 141 at one end for connecting the first and second connecting unit groups 30, 40, and a test sample connection portion 132, 142 at the other end for connecting the male head c1 and the female head c2 of the quick-release connector c under test, respectively. In this embodiment, the test sample connection portions 132, 142 are provided with locking or locking structures (e.g., internal threads) for the male and female heads c1, c2 of the quick-release connector c under test to be locked or locked into them. To ensure that the first adapter 13 and the second adapter 14 are stably positioned during the test, the fixing base 12 is provided with a groove 121 (e.g., a V-shaped groove or an arc-shaped groove) and a window 122 located below the groove 121. The first adapter 13 and the second adapter 14 are placed on the groove 121 and are fixed on the outer surface of the first adapter 13 and the second adapter 14 by a fixing element 15 (e.g., but not limited to a metal clamp) and fixed through the window 122. This allows the first adapter 13 and the second adapter 14 to move stably and without wobbling along with the slide assembly 11, and to move the male connector c1 and the female connector c2 of the quick-release connector being tested to mate in opposite directions or to separate in opposite directions. On the other hand, if a large number of quick-release connectors of different sizes or types need to be tested, only the corresponding first adapter 13 and second adapter 14 need to be replaced, and the stroke of the slide assembly 11 needs to be adjusted, so that a variety of tests can be completed using the same equipment.

[0048] Please refer to the following: Figure 1A , Figure 1B and cooperate Figure 4 As 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 the leakage and trapped air volume. 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 opening 211 or the second opening 221, and then one of the openings can be closed. In some embodiments, the first measuring tube 21 and the second measuring tube 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.

[0049] The lower end of the first measuring tube 21 is connected to the first adapter 13 via the first connecting unit group 30, and the lower end of the second measuring tube 22 is connected to the second 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 first adapter 13, and the second adapter 14, the separation leakage or trapped air volume can be measured during the repeated docking and disengagement of the quick-release connector c under test.

[0050] 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 is connected to the lower end of the first measuring tube 21 and is connected to the first adapter 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 tube 22 through the third connecting pipe 42 and is connected to the second adapter 14 through the fourth connecting pipe 43.

[0051] Please continue reading Figure 1A , Figure 1B As shown, this invention places the sliding device, the measuring tube assembly, and the first and second connecting unit assemblies all on a fixed unit 51, such as a fixed wall, back plate, or perforated plate, so that these components are positioned on the fixed unit 51 and do not shift during testing. Additionally, a vibrator 52 is selectively installed on the fixed unit 51, adjacent to the first measuring tube 21, to slightly vibrate the first measuring tube 21 during measurement, thereby quickly expelling air bubbles and avoiding data errors caused by bubble interference.

[0052] The following explanation will use the quick-release coupling of a liquid pipeline as an example to illustrate the measurement of trapped air volume using the equipment of this invention. Please refer to this example. Figure 1A , Figure 1B , Figure 2A , Figure 2B , Figure 3A , Figure 3B , Figure 4 and Figure 5 As shown.

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

[0054] like Figure 2B As shown, the male connector c1 and female connector c2 of the quick-release connector c to be tested can be first installed on the test sample connection parts 132 and 142 of the first adapter 13 and the second adapter 14, respectively, and ensure that the male connector c1 and female connector c2 are firmly fixed in the groove 121 of the fixing base 12. Then, as shown... 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.

[0055] like Figure 1A , Figure 1B , Figure 3A , Figure 4 and Figure 5 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 measuring tube 21 and the second measuring tube 22 reach a predetermined height (e.g., 2 / 3 of the height of the first measuring tube 21 and the second measuring tube 22). Water injection is then stopped, and the water level positions in the first measuring tube 21 and the second measuring tube 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.

[0056] Step 2: Seal

[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 media flow.

[0058] Step 3: Perform disconnection / docking

[0059] The operator can control the sliding device 10 via an external control switch using pneumatic, electrical, or hydraulic methods. Figure 3A , Figure 3B and Figure 5 It can be seen that the two slides 111 of the slide assembly 11 slide in opposite directions on the base 16, so that the first adapter 13 and the second adapter 14 gradually separate from the docking state, and complete the separation action of the male head c1 and the female head c2.

[0060] 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 allows the first adapter 13 and the second adapter 14 to gradually approach each other from their separated state, completing the docking action between 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 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.

[0061] Step 4: Repeat the separation / docking process:

[0062] Repeat the separation / connection action of male connector c1 and female connector c2 in step 3. Repeat the separation / connection test in this way until the water level of the internal medium in the first measuring tube 21 on the left drops to the target scale (e.g., 10 scales). Stop the test after 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.

[0063] The following explanation will use the quick-release coupling of a liquid pipeline as an example to illustrate the measurement of separation leakage. Please refer to the same diagram; this test is largely the same as the aforementioned air trapping measurement, with the following differences:

[0064] Step 2: Seal

[0065] 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 flow of the medium.

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

[0067] Repeat the separation / connection process of male connector c1 and female connector c2 in step 3. 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., 10 scale divisions). Stop the test after maintaining the connection between male connector c1 and female connector c2, and record the number of connections to calculate the average separation leakage.

[0068] Thus, the advantages of performing the above two measurements using the device of this utility model are:

[0069] 1. The testing operation is convenient.

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

[0071] 3. The same equipment can be used to perform two tests: separation leakage and trapped air volume. Different tests can be completed by simply switching between them, saving testing costs.

[0072] 4. It is operable and feasible.

[0073] In summary, this invention provides precise control over the docking / disconnection of quick-release connectors via the sliding device 10, and can be applied to quick-release connectors of various types and sizes by simply replacing or adjusting the corresponding first adapter 13 and second adapter 14. Furthermore, through the measuring tube assembly 20 and the first and second connecting unit assemblies 30 and 40, the operator can accurately and conveniently measure two important parameters: separation leakage and trapped air volume. In addition, the optional vibrator 52 assists in removing air bubbles, effectively improving the reliability of the measurement data.

[0074] The above description is a detailed account of the preferred embodiments of this utility model. Any equivalent or similar modifications made based on the teachings disclosed in this utility model are naturally included within the protection scope of this utility model patent. Through the technical concept and combination method of this utility model, not only are the problems of unstable testing and inaccurate data faced by the prior art solved, but a highly efficient, multifunctional, and economical quick-release connector measuring device is also provided.
