About Me

Vacuum Box Method Detection Principle: Liquid cooling plate to be tested is directly connected to a mass spectrometer and put inside a chamber. Vacuum is created inside the part and the helium concentration in the chamber is raised to 100%. If a leakage is present, the molecules of helium migrate into the part and the leakage is measured by the spectrometer. 1. The high-pressure gas detects large leaks, and at the same time completes the strength detection; 2. Vacuum box vacuuming and background suppression; 3. The workpiece is evacuated and filled with helium; 4. Helium mass spectrometer detects small leaks;
