Liquid working medium perfluorotriethylamine leakage test method

The invention discloses a leakage test method for a thermal conductive coolant perfluorotriethylamine (C6F15N) liquid working medium for space products. As liquid perfluorotriethylamine is volatile, perfluorotriethylamine leaked in an unsaturated state can be fully volatilized as a gaseous substance through stirring by a fan, and the amount of leaked perfluorotriethylamine is tested by use of an atmospheric level-4 mass spectrometer leak detection technology. Through the test method of the invention, the actual leakage of a working medium after filling can be tested for a product adopting liquid perfluorotriethylamine as a working medium in the refrigeration industry. Compared with the existing leak detection method using a leak detection medium gas, the method of the invention can reflect the actual leakage condition of a product in a more real and accurate way. 本发明公开了种航天产品用导热冷却剂全氟三乙胺(CFN)液态工质的泄漏量测试方法，利用液态物质全氟三乙胺的易挥发性特性，在未饱和的状态下泄漏的全氟三乙胺通过风机搅拌可以完全挥发为气态物质,利用大气四级质谱检漏技术测试方法实现全氟三乙胺的泄漏量测试。本发明的测试方法可以实现制冷行业采用液态全氟三乙胺
