Leak-Tightness Testing in the Liquid-Cooled Heat Dissipation Industry

Quick Q&A: How Are Leak Tests Conducted on Liquid-Cooling Plates and Copper Tube Assemblies? Jingcheng Engineering’s Comprehensive Guide to Applications in the Liquid-Cooling Industry

2026-08-15

This article provides a systematic overview of technical solutions and key selection criteria for airtightness testing in the liquid cooling industry. For products such as liquid cooling plates and copper tube assemblies, JCGK employs a combined solution consisting of “testing instruments + custom fixtures + multi-channel testing + automation interfaces,” The core of this approach involves verifying the sealing reliability of enclosed flow channels using either the direct pressure method or the differential pressure method. It emphasizes that in mass production scenarios, six key factors—test pressure, leakage standards, product volume, testing cycle time, fixture design, and automation interfaces—must be comprehensively considered.

Q&A: Why Do New Energy Vehicles Need to Undergo Comprehensive Airtightness Testing? To Avoid the Risk of Large-Scale Recalls

2026-08-08

Taking the recall of 33,473 Xpeng X9 vehicles due to air spring airtightness defects as a starting point, this article analyzes the importance of airtightness testing for new energy vehicles. The article points out that core components of new energy vehicles demand higher standards for sealing reliability, driving the transition from spot checks to 100% inspection for airtightness testing. It introduces two testing principles—the direct pressure method and the differential pressure method—and uses the Jingcheng Engineering JC-C10005 series as an example to demonstrate that domestically produced equipment has achieved high-precision micro-leak detection, wide pressure adaptability, and automated integration into production lines.
