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

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.

Applications of JCGK Leak Detection Equipment from Jingcheng Engineering in the Automotive Industry: From Component Testing to Supply Chain Collaboration
