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.

Q&A: How Can Leak Testers Improve Production Line Throughput? A Case Study of Optimizing Test Efficiency Using JCGK’s Engineering Model

This article analyzes the root causes of low efficiency in airtightness testing production lines at manufacturing enterprises: traditional testing equipment must complete a fixed test cycle regardless of whether a product has been deemed defective, resulting in a significant amount of “unnecessary waiting.” The article introduces JCGK’s solution—an intelligent early-detection feature that shortens the testing time per unit while retaining an engineering mode for comprehensive data collection during the R&D phase—and elaborates on efficiency-enhancing measures such as parameter optimization and multi-station parallel processing.
