Description

Technical Field

[0001] This application relates to the field of server technology, and more specifically, to an airtightness detection device and a server. Background Technology

[0002] Currently, liquid-cooled servers are widely used in data centers, high-performance computing centers, and research institutions due to their superior heat dissipation capabilities and space utilization. The core of a liquid-cooled server lies in its liquid cooling system, and the airtightness of this system is a key factor determining its performance stability and lifespan. Traditional airtightness testing techniques mainly include the gas filling method, differential pressure method, and helium mass spectrometry leak detection method. The gas filling method is the most basic, involving injecting compressed gas into the component under test and checking whether the pressure decreases over time to determine if a leak exists. The differential pressure method establishes a pressure balance between the component under test and a known leak-free standard component, then monitors the pressure difference between the two to determine the airtightness of the component under test. The helium mass spectrometry leak detection method uses helium as a tracer gas. Combined with the high sensitivity of a mass spectrometer, the detection of trace amounts of helium can accurately locate leaks. This detection method is particularly suitable for applications requiring high-precision testing.

[0003] While the above technologies meet the basic requirements for airtightness testing of liquid-cooled servers to some extent, several significant problems remain in practical applications. First, the gas filling method has limited accuracy and insufficient detection capability for minute leaks, easily leading to misjudgments, especially under high pressure environments where detecting minute leaks is even more difficult. Second, although the differential pressure method improves detection accuracy, it requires standard components, increasing testing costs and complexity, and has high environmental requirements, making it difficult to operate on-site. Third, while helium mass spectrometry leak detection offers high accuracy, it consumes a large amount of helium, and the equipment is expensive and maintenance costs are high, making it unsuitable for large-scale or frequent testing needs. Furthermore, existing technologies generally suffer from cumbersome operating procedures, low automation, low testing efficiency, and high requirements for operator skills, all of which hinder the widespread adoption and efficiency of airtightness testing for liquid-cooled servers.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] To solve the technical problems of the background technology, such as Figures 1 to 3 As shown, this embodiment first provides an airtightness testing device, which is used to test the airtightness of a target component 1. The target component 1 has a target air inlet 101 and a target air outlet 102. The airtightness testing device includes:

[0039] Detect housing 2;

[0040] An air intake pipe 3 is installed inside the detection housing 2. The first end of the air intake pipe 3 extends out of the detection housing 2 for connection with an external air supply device, which is used to store inert gas.

[0041] An inert gas detection structure 4 is disposed inside the detection housing 2. The inert gas detection structure 4 includes a detection pipeline 401 and a detection unit. One end of the detection pipeline 401 is used to connect to the second end of the air inlet pipe 3 so as to detect the inert gas input into the detection pipeline 401 through the detection unit.

[0042] The controller is installed on the detection housing 2 and connected to the detection unit to determine whether the inert gas meets the preset standard based on the detection results of the detection unit.

[0043] An airtightness testing unit 5 is installed inside the testing housing 2 and connected to the controller. The inlet of the airtightness testing unit 5 is connected to the gas supply equipment, and the outlet of the airtightness testing unit 5 is connected to the target air inlet 101, so as to deliver inert gas that meets the preset standard to the target component 1. The preset standard is that the concentration of the inert gas needs to meet the set concentration, so as to provide a reliable basis for subsequent measurements.

[0044] By using the inert gas detection structure 4, especially the high-precision detection unit, the inert gas filled into the target component 1 can be accurately detected. Even a small leak can be effectively identified, which significantly improves the accuracy and reliability of airtightness detection and avoids misjudgment caused by impure gas or insensitive leak detection in the prior art. At the same time, it can also be determined that the inert gas can enter the detection pipeline 401 through the second input pipeline 701, avoiding testing when the second input pipeline 701 is blocked.

[0045] The connection between the controller and the detection unit enables automated control and analysis of the inert gas detection process. It can automatically determine whether the gas meets the preset standards based on the feedback results from the detection unit, without the need for manual intervention, thereby improving detection efficiency and reducing errors that may be caused by human operation.

[0046] Using inert gases such as nitrogen for detection reduces the potential risks of explosion, combustion, or chemical reaction compared to other gases that may be used in the prior art, thus improving the safety of the detection process.

[0047] The inlet of the air tightness testing unit 5 is directly connected to the air supply equipment, and the outlet is connected to the target air inlet 101 of the target component 1. This simplifies the connection process between the testing equipment and the target component 1, avoids complex pipeline layout, reduces the difficulty of operation, and improves the user-friendliness of the testing device.

[0048] Furthermore, the detection unit includes a concentration detection component 402 to detect the presence of inert gas in the pipeline 401.

[0049] The concentration detection component 402 can accurately detect the concentration of inert gas in the detection pipeline 401, ensuring that only the preset standard inert gas is filled into the target component 1, avoiding the test deviation caused by the mixing of other impurities or non-inert gases in the prior art, and improving the accuracy and reliability of the test.

[0050] By monitoring the concentration of inert gas in the pipeline in real time through the concentration detection component 402, changes in gas concentration caused by leaks can be identified earlier, thereby improving the sensitivity of airtightness detection. Even minute leaks can be detected in time, which is especially important for high-precision airtightness testing.

[0051] Before inflation, the purity of the gas is confirmed by the concentration detection component 402, ensuring the consistency of the pre-test conditions, avoiding repeated tests or invalid test results due to gas source problems, optimizing the test process, and improving work efficiency.

[0052] The use of a high-precision concentration detection component 402 ensures that the gas introduced during the test is an inert gas, avoiding potential chemical reactions or explosion risks and improving the safety of the test process.

[0053] The data from the concentration detection component 402 can be recorded and analyzed by the controller. This data not only helps to determine the airtightness status of the current test, but can also be used for quality control and equipment maintenance, providing data support for subsequent troubleshooting and performance optimization.

[0054] Furthermore, the detection unit also includes a first pressure reducing component 403 disposed upstream of the concentration detection component 402, so as to reduce the pressure of the inert gas in the detection pipeline 401 by means of the first pressure reducing component 403.

[0055] The first pressure reducing component 403 can reduce the inert gas pressure in the detection pipeline 401 to a pressure range suitable for the operation of the concentration detection component 402, thereby preventing damage to the concentration detection component 402 due to excessive pressure. Since different detection components have different optimal operating performance under different pressures, pressure reduction can eliminate interference that may be caused by high pressure, allowing the concentration detection component 402 to operate under optimal conditions, thereby improving detection accuracy and precision.

[0056] Furthermore, the airtightness detection unit 5 includes: a first input pipe 501 and a first on / off valve 502. The two ports of the first input pipe 501 are respectively used to connect to the second end and the target air inlet 101. The first on / off valve 502 is installed on the first input pipe 501 and connected to the controller so that when the inert gas meets the preset standard, the first on / off valve 502 is in the open state, so that the inert gas that meets the preset standard enters the target component 1 through the first input pipe 501.

[0057] The first on / off valve 502 is designed to connect to the controller and control the valve's opening and closing state based on received signals. When the concentration and pressure of an inert gas (such as nitrogen) meet preset standards, the first on / off valve 502 automatically opens, allowing the gas to enter the target component 1 (the cold plate piping of the liquid-cooled server) through the first input pipe 501. This design ensures that only strictly controlled, standard-compliant gases can be used for airtightness testing, avoiding test errors that may be caused by the introduction of non-standard gases.

[0058] Air tightness testing requires a stable and precise gas input process. The automated control of the first on / off valve 502, combined with the optimized design of the first input pipeline 501, enables the gas input process to be completed quickly and accurately, avoiding the uncertainties of manual operation and thus significantly improving testing efficiency.

[0059] By controlling the gas input through the first on / off valve 502, excessive or substandard gas can be effectively prevented from entering the target component 1, thus avoiding potential safety hazards such as gas leakage or overpressure damage.

[0060] The state changes (open or closed) of the first on / off valve 502 can be recorded by the controller as part of the test process data. This information helps in later analysis of the accuracy and reliability of the test, such as determining whether the gas quality was stable before the test.

[0061] The setup of the first input pipe 501 and the first on / off valve 502 facilitates the establishment of a standardized testing procedure. Before each test, the gas quality must be verified against a preset standard; once verification is passed, the test begins immediately. This standardized procedure not only improves testing efficiency but also ensures the consistency and comparability of test results.

[0062] Furthermore, the airtightness detection unit 5 also includes a temperature detection component 503, which is disposed on the first input pipe 501 and located downstream of the first on / off valve 502, to detect the real-time temperature of the inert gas entering the target component 1.

[0063] The physical properties of gases, including pressure and volume, are greatly affected by temperature. The temperature detection component 503 can monitor the temperature of the inert gas entering the target component 1 (the cold plate piping of the liquid-cooled server) in real time. This data will be used to correct the readings of the pressure detection component 504 and the concentration detection component 402 to eliminate the influence of temperature changes on the detection results.

[0064] The temperature of a gas may fluctuate under different environmental conditions. The addition of the temperature detection component 503 enables the airtightness testing device to adapt to various temperature environments. Whether under high or low temperature conditions, it can ensure the normal progress of the test process and the validity of the results through real-time temperature monitoring and adjustment.

[0065] The temperature detection component 503 can also monitor whether the gas temperature is within the safe operating range, avoiding damage to the liquid-cooled server and testing equipment caused by high-temperature or excessively cold gas, and ensuring the safety of the testing process.

[0066] Furthermore, the airtightness detection unit 5 also includes a pressure detection component 504, which is disposed on the first input pipe 501 and located downstream of the temperature detection component 503, to detect the real-time pressure entering the target component 1.

[0067] The pressure detection component 504 directly monitors the real-time pressure of the gas entering the target component 1 (i.e., the liquid-cooled server cold plate piping), ensuring the consistency and accuracy of pressure conditions during testing. In a liquid cooling system, pressure is a crucial parameter, directly affecting the sealing performance testing of various system components. Real-time pressure detection allows the equipment to monitor the pressure status of the incoming gas at any given time, which is essential for accurately determining airtightness.

[0068] Since the temperature sensing component 503 is located upstream of the pressure sensing component 504, the two work together to achieve accurate pressure measurement after temperature compensation. Gas pressure is significantly affected by temperature. The gas temperature data monitored by the temperature sensing component 503 is used to correct the reading of the pressure sensing component 504, eliminating measurement errors caused by temperature changes, ensuring accurate pressure values ​​can be obtained under any temperature conditions, and thus improving the overall accuracy of the airtightness test.

[0069] Furthermore, the airtightness testing device also includes a main pipeline, a gas collection component 6, and a gas source processing unit 7. The inlet end of the main pipeline is connected to the gas supply equipment. The gas collection component 6 is provided with at least two gas collection ports 601 and a first gas outlet. There are at least two main pipelines, and at least two main pipelines are provided in a one-to-one correspondence with at least two gas collection ports 601. The outlet end of each main pipeline is connected to its corresponding gas collection port 601. The first gas outlet is connected to the gas source processing unit 7 so that the inert gas is pretreated by the gas source processing unit 7 and the treated inert gas is input into the target component 1.

[0070] By setting up at least two main pipelines and corresponding gas collection ports 601, the airtightness testing device can simultaneously handle inert gases from multiple gas supply devices. This multi-supply capability enhances the flexibility of the device, effectively supporting simultaneous airtightness testing of multiple target components 1 (cold plate piping of liquid-cooled servers), greatly improving testing efficiency and production capacity.

[0071] The gas source processing unit 7 pre-treats the inert gas, including but not limited to filtration, drying, and pressure regulation. This process ensures that the gas input into the target component 1 is clean, dry, and has stable pressure, avoiding interference from impurities, moisture, or pressure fluctuations on the test results, thereby improving the accuracy and reliability of the test.

[0072] By centrally managing and distributing the gas through the gas collection component 6, the use of gas resources can be optimized. When processing multiple target components 1 simultaneously, gas waste can be avoided, especially under high-pressure or high-flow-rate testing conditions. This optimization method can significantly reduce gas consumption costs.

[0073] The at least two gas collection ports 601 on the gas collection component 6, along with the corresponding total number of pipes, give the airtightness testing device good adaptability and scalability. As production needs change or testing requirements upgrade, the testing coverage can be expanded by adding more gas collection ports 601 and total pipes without major modifications to the entire device. At the same time, the multiple gas collection ports 601 also ensure the stability of the inert gas input.

[0074] Furthermore, the gas source processing unit 7 includes a second input pipe 701 and a control valve assembly 702. The two ends of the second input pipe 701 are respectively connected to the first air outlet and the target air inlet 101. The control valve assembly 702 is disposed on the second input pipe 701 so as to control the opening and closing of the second input pipe 701.

[0075] The control valve assembly 702 precisely controls the flow rate of inert gas entering the target component 1 (the cold plate piping of the liquid-cooled server) by adjusting the valve opening. This precise control is particularly important for airtightness testing, as the gas flow rate needs to be stable at a preset value during the test to ensure the accuracy of the test results. Excessive flow rate or flow rate fluctuations can lead to test errors.

[0076] The control valve assembly 702, connected to the controller, can respond to signals from the controller and automatically adjust the valve state to automate the airtightness test. At different stages of the test, the controller sends different commands as needed, and the control valve assembly 702 adjusts the valve opening according to these commands to ensure a smooth testing process.

[0077] When the control valve assembly 702 detects an abnormal situation (such as abnormal pressure or gas leakage), it can quickly close the valve to prevent excessive inert gas from entering the system and avoid potential safety hazards. This safety mechanism is particularly important for testing in high-pressure gas environments, helping to protect the safety of equipment and operators.

[0078] The second input pipe 701 connects the first air outlet and the target air inlet 101. The process typically involves pre-treatment of the gas by the gas source processing unit 7, such as pressure regulation and impurity filtration. The control valve assembly 702, located on the second input pipe 701, prevents the treated gas from being contaminated by the external environment during transmission, ensuring the quality of the gas input into the target component 1. The control valve assembly 702 includes a manual valve and an automatic valve arranged in sequence. The use of these two valves ensures that the gas flow will not stop due to the failure of one of the valves during the airtightness testing of the target component.

[0079] Furthermore, the gas source processing unit 7 also includes an air filter component 703, which is disposed on the second input pipe 701 and located downstream of the control valve assembly 702, so as to filter solid particulate impurities in the inert gas through the air filter component 703.

[0080] The air filter component 703 effectively filters solid particulate impurities such as dust and metal shavings from inert gases, improving gas purity, which is crucial for airtightness testing. Pure gas prevents impurities from depositing on the surface of the test component, preventing misjudgments during the testing process and ensuring the accuracy and reliability of test results.

[0081] By removing impurities from the gas, the air filter component 703 also protects the testing equipment, especially sensitive sensors and valves from wear or blockage, extending the service life of the equipment and reducing maintenance costs.

[0082] In some applications, solid particulate impurities may be propelled by high-pressure gas into high-speed projectiles, potentially damaging testing equipment and posing safety hazards. Air filter component 703 effectively reduces this risk, ensuring the safety of the entire testing process.

[0083] Furthermore, the gas source processing unit 7 also includes an oil mist separation component 704, which is disposed on the second input pipe 701 and located downstream of the air filter component 703, so as to separate oil mist and oil in the inert gas after being filtered by the air filter component 703.

[0084] Oil mist and oil are common in compressed gases, originating from the gas source itself or during transmission. The oil mist separator 704 effectively removes these oily components, further improving the cleanliness of the inert gas.

[0085] Oil mist and oil can not only affect test results, but also corrode the metal components inside the testing equipment. The use of the oil mist separator 704 can protect the equipment from oily substances, extend the service life of the equipment, and reduce maintenance costs.

[0086] Oil mist can pose a safety hazard under high-pressure environments, especially near electrical circuits, where its presence could cause short circuits or fires. The oil mist separation component 704 eliminates this risk, ensuring the safety of the testing process.

[0087] Furthermore, the gas source processing unit 7 also includes a second pressure reducing component 705, which is disposed on the second input pipe 701 and located downstream of the oil mist separation component 704, so as to reduce the pressure of the inert gas entering the target component 1 by means of the second pressure reducing component 705.

[0088] The second pressure-reducing component 705 can reduce the pressure of the inert gas entering the target component 1 (liquid-cooled server cold plate piping) to a safe range. High-pressure gas entering the target component 1 directly without pressure reduction may damage other structures within the target component 1, such as causing deformation or destruction of the sealing structure. Adjustment by the second pressure-reducing component 705 can avoid this overpressure risk, ensuring the safety of the target component 1.

[0089] The second pressure reducing component 705 can adjust the gas pressure to the preset test pressure, ensuring that each test sample is tested under the same pressure conditions, thereby improving the comparability and consistency of test results and facilitating the standardization of test procedures and data analysis.

[0090] Furthermore, the air tightness detection unit 5 also includes an air outlet pipe 8 disposed on the detection housing 2, one end of which is connected to the target air outlet 102 to introduce inert gas inside the target component 1 into the detection housing 2.

[0091] The connection between the exhaust pipe 8 and the target exhaust port 102 forms a closed-loop detection system, allowing the inert gas injected into the target component 1 (the cold plate piping of the liquid-cooled server) to return to the detection housing 2 instead of being directly released into the environment. This not only saves gas resources and reduces testing costs, but also benefits environmental protection by avoiding the safety and pollution problems that may be caused by high-pressure gas emissions.

[0092] In a closed-loop system, the gas recovered through the outlet pipe 8 can re-enter the pressure sensor inside the detection housing 2 for secondary detection. This increases the basis for judging airtightness. Especially when detecting minor leaks, gas recovery and re-detection can improve the sensitivity of leak detection, reduce false positive or false negative test results, and thus improve the overall accuracy and reliability of the test.

[0093] During the airtightness testing of liquid-cooled servers, the release of high-pressure gas could damage sensitive components or pose a safety threat to operators. The design of the exhaust pipe 8 ensures that the gas circulates in a controlled environment, avoiding the risk of direct release and enhancing the safety of the entire testing process.

[0094] Furthermore, the outlet pipe 8 is provided with an outlet valve 801 and a flow detection component 802 in sequence along the outflow direction of the inert gas, so as to detect the flow rate of the inert gas flowing out from the target outlet 102 through the flow detection component.

[0095] The outlet valve 801 can precisely control the flow rate of inert gas from the target outlet 102, ensuring that the gas discharge speed meets the test requirements. Especially after the pressure holding test, by adjusting the opening of the outlet valve, the gas can be released smoothly, avoiding test errors caused by instantaneous pressure drop.

[0096] The flow detection component 802 can monitor the gas flow rate in real time, which is especially crucial for detecting minute leaks. By comparing the flow rate difference between the inflation and deflation phases, the airtightness of the component can be assessed, improving the accuracy and reliability of the test.

[0097] In airtightness testing, the flow data monitored by the flow detection component 802 can serve as an independent means of verifying the test results. Even if no significant pressure drop is detected during the pressure holding phase, abnormal flow during the venting phase can indicate the presence of minor leaks, ensuring the comprehensiveness and reliability of the test results.

[0098] After the test is completed, the exhaust process is monitored by the flow detection component 802. If an abnormal flow is found (such as a flow rate much higher than expected), it may be that there is still a large undetected leak inside the target component 1. At this time, the exhaust valve 801 can be quickly closed to prevent safety hazards and property damage caused by a large amount of gas leakage.

[0099] Furthermore, the detection housing 2 is provided with a hook component 9 to hook at least a portion of the main pipe of the airtightness detection device.

[0100] The hook component 9 is designed to prevent the main pipeline from being scattered haphazardly, reduce the tangling and friction between the various pipelines, lower the risk of pipeline damage, ensure the smooth and stable flow of the pipeline during the testing process, and improve testing efficiency.

[0101] Furthermore, the detection housing 2 is provided with an exhaust port 10 to exhaust the air inside the detection housing 2 to the outside of the detection housing 2.

[0102] The exhaust vent 10 allows the heat generated by the detection housing 2 to be discharged in a timely manner.

[0103] Furthermore, the detection housing 2 is provided with an ambient temperature, humidity and oxygen content detection element 11 to detect the temperature, humidity and oxygen content inside the detection housing 2 in real time; and / or, the bottom of the detection housing 2 is provided with a support member 12 to support the detection housing 2.

[0104] The ambient temperature, humidity and oxygen content detection component 11 can monitor environmental parameters inside the detection housing 2 in real time, including temperature, humidity and oxygen content. This provides accurate environmental background data for airtightness testing and helps to evaluate the effectiveness and reliability of the test.

[0105] By monitoring environmental parameters in real time, it can be ensured that all tests are conducted under similar or consistent conditions, thus achieving test standardization and facilitating subsequent analysis and comparison of results.

[0106] The support component 12 located at the bottom of the test housing 2 provides a stable support, ensuring that the test housing 2 will not be displaced or shaken due to external forces or internal vibrations during the test.

[0107] Furthermore, a sliding component 13 is provided on the detection housing 2. The sliding component 13 is rotatably disposed relative to the detection housing 2 so as to drive the detection housing 2 to move.

[0108] The sliding component 13 is a sliding wheel. The setting of the sliding component 13 ensures that the detection housing 2 can move.

[0109] Furthermore, a support member 14 is provided on the detection housing 2. The support member 14 is used to support the scanning member so that the scanning member can scan the information of the detection housing 2.

[0110] The supporting component 14 is a supporting groove provided on the detection housing 2, which can be used to place the scanning component. In this embodiment, the scanning component can be a barcode scanner, which can ensure that the staff can obtain the information of the target component 1 anytime and anywhere.

[0111] This application also provides a server, which includes a liquid cooling plate and an airtightness detection device, wherein the airtightness detection device is the airtightness detection device described above.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application.
