Liquid-cooled systems must undergo air-tightness testing

Liquid-Cooled Leak Testing: With the National Standard Set to Take Effect in 2026, How Should Companies Establish a Mass Production Quality Inspection System?

This article outlines the key points of airtightness testing for liquid-cooled data centers: The new national standard set to take effect in 2026 only establishes a framework, with leakage rates to be determined by the product manufacturer; it compares the applicable scenarios for four testing methods—direct pressure, differential pressure, flow rate, and helium leak testing; it points out that fluctuations in results are often due to system factors such as test fixtures and temperature rather than the instruments themselves; It emphasizes that companies should establish their own testing specification matrices to translate standards into stable, traceable mass-production testing capabilities.

How to Choose a Leak Test Solution for Liquid-Cooled Plates? A Decision-Making Model Based on Three Factors: Leak Rate Requirements, Daily Production Volume, and Operating Costs

This article addresses the scenario of 100% inspection on production lines in the airtightness testing industry, emphasizing that repeatability is more critical than accuracy. Based on 11 consecutive sets of actual measurement data from the JCGK Direct-Pressure Airtightness Tester by Jingcheng Engineering, the study verifies that its leakage values remain stable at 6–7 Pa, with fluctuations of only ±1 Pa. The paper analyzes the three key technological pillars supporting this performance—high-precision sensors, proprietary gas path control, and temperature drift compensation algorithms—and concludes with recommendations for selecting the appropriate model for different pressure scenarios.

Q&A: Why Is Leak Tightness Testing the First Line of Defense for Reliability Against the Risk of Micro-Leaks in Data Center Liquid Cooling Systems?

This article analyzes the requirements for high-precision airtightness testing in liquid-cooling systems for AI data centers and points out that the risk of micro-leaks is a core threat to system reliability. Using the Shenzhen Jingcheng Engineering JC-C10005 differential pressure leak tester as an example, the article illustrates how domestically manufactured equipment—through flexible customization, rapid response, and cost advantages—is gradually replacing imported equipment. It has become a critical component in the initial inspection of liquid-cooling production lines and, in combination with helium leak testing, helps ensure the autonomy and controllability of the industrial chain.

Quick Q&A: What’s the Difference Between Differential Pressure and Flow-Type Leak Detectors? Everything You Need to Know in One Article—Don’t Make the Wrong Choice Again

This article systematically compares the key differences between differential pressure-type and flow-type airtightness testers. Differential pressure-type testers detect micro-leaks by comparing pressure changes between the test specimen and a standard reference chamber. They are resistant to temperature drift, offer high accuracy, and provide excellent repeatability, making them suitable for applications with high sealing requirements, such as new energy battery packs and automotive electronics; Flow-type testers directly measure the volume of gas leaked per unit time. They excel at identifying large leaks, measuring gas flow rates, and detecting blockages, making them suitable for flow performance analysis of valves, nozzles, and permeable membranes. The two types are not ranked as superior or inferior; rather, the choice depends on whether the testing objective is to determine "leakage" or "gas flow."
