基于氦气质谱法的动力电池包热管理模块密封性检测系统
Sealing Detection System for Thermal Management Module of Power Battery Pack Based on Helium Mass Spectrometry
摘要
Abstract
According to the sealing inspection requirements of the thermal management module of the power battery pack,a sealing inspection system for the thermal management module of the power battery pack based on helium mass spectrometry is proposed.To avoid helium leakage pollution,first use low helium for large leakage rough inspection,and then use helium for fine inspection;By using processes such as helium recovery and nitrogen cleaning,the cost of testing is reduced and the reliability of testing is improved;Adopting a dual true empty box alternating working mode to improve detection efficiency.Through experimental verification,the minimum detection leakage rate is less than 1.5×10-6 mbar·L/s,which meets the sealing detection requirements of the power battery pack thermal management module.关键词
