Today, as liquid cooling technology accelerates its penetration into servers, data centers and high-end storage equipment, liquid cooling components have become the core support of "computing infrastructure". However, for a long time, many liquid cooling manufacturers have faced "dilemmas" in seal testing: traditional air tightness testing procedures are complex and have a high false detection rate; helium mass spectrometry leak detection is accurate but costly and complex to operate.How to find the ideal solution with “accuracy exceeding air tightness and cost lower than helium inspection”?Hirays will answer your questions through the practical case of hydrogen-nitrogen leakage detection in liquid-cooling tube seal detection.

Customer case

A server customer needed to conduct batch sealing testing of liquid-cooled pipelines. They initially purchased other brands of airtightness testing equipment and helium testing equipment, but fell into the dilemma of "frequent mistesting of airtightness→manual leak detection→low efficiency" and "excessive helium detection accuracy, resulting in low yield rate, high retest rate, and high detection cost":

⬆Pre-renovation plan   High misjudgment rate: Equipment often causes mismeasurements or even failure to measure due to fluctuations in ambient temperature and humidity, impurities on the workpiece surface, or subtle deviations in parameters. The process is complex: In order to find leaks, the product must use traditional methods such as soaking in water and observing bubbles with the naked eye to find leaks. This is not only time-consuming and labor-intensive, but also poses a potential risk of damage to precision components. Long test time: The existing air tightness test takes about 15 minutes (excluding naked eye recognition and waiting time), which is inefficient. Production capacity is dragged down: The cumbersome review process seriously slows down the pace of the production line and becomes an "invisible bottleneck" that restricts the release of production capacity.

⬆The helium testing equipment purchased by the customer has been idle “We needed a set of accuracy that could go beyond airtight 10-4level, and the overall cost is much lower than the detection solution of helium mass spectrometry leak detection!"The customer project leader frankly expressed the urgent needs at that time.


solution  After understanding the customer's predicament, Hirays technical personnel went deep into the customer's production line to help analyze the cause and provide reliable solutions. They recommended the HQ series hydrogen and nitrogen leak detector (which integrates filling, detection, analysis, and waste gas treatment).The customer was very interested in this and immediately applied for a one-week on-site trial of the prototype.

⬆Customer on-site trial of Hirays hydrogen and nitrogen detection equipment During the trial period, the professional technical team of Hirays provided detailed operational training and selection guidance, and based on the characteristics of the liquid cooling pipeline, it was recommended to use the "sniffing mode" to accurately locate leaks. This mode is simple and intuitive to operate, requires low operator skills, and can achieve high-precision detection (accuracy up to 5×10⁻⁸ Pa·m³/s) at a lower cost, which perfectly meets customers' multiple demands for "ease of use", "economy", and "high efficiency". It has been verified by actual testing that customers are attracted by the strength of the Helius hydrogen and nitrogen leak detector, especially because the equipment is stable and efficient (a single cycle time is about 1 minute) and the detection cost is low (only 1/20 of the helium detection cost).After the trial, they decisively purchased multiple HQ-200 hydrogen and nitrogen leak detectors, paired with HQ-100 test probes, and quickly deployed them on the production line.


Effect feedback

After a period of stable operation, customers spoke highly of the Hirays hydrogen and nitrogen leak detector: 01 Save processes and improve yield rate Hydrogen-nitrogen tracer testing eliminates the cumbersome process of air tightness testing, significantly reduces misjudgments and missed judgments, and significantly improves product yield. 02 Improve efficiency and ensure production capacity Compared with the air-tight inspection, the test cycle of a single piece of liquid-cooled tube is 90% shorter than before under the same leak rate detection accuracy, and 10% to 15% shorter than the helium inspection. The efficiency is greatly improved, ensuring the smooth and efficient operation of the production line. 03 Reduce costs and increase benefits Only one hydrogen-nitrogen detector is needed to complete the test. The cost of hydrogen-nitrogen gas is low, and there is no need to purchase additional auxiliary equipment such as booster pumps and independent exhaust gas treatment devices, which greatly reduces investment and operating costs.
