摘要
为解决新能源汽车控制模块的内腔锈蚀问题,对传统燃油车冷却系统中腔体形成的腐蚀关键因子进行了分析,并根据等离子浓度正交试验,模拟冷却介质的等效离子浓度,寻找腐蚀影响因子;通过对比不同腐蚀介质下铝基材的不同腐蚀速率,论证了传统试验方法对新能源控制系统的适用性,并设计了腔体堵塞试验,验证了受影响条件下冷却系统因腐蚀引发系统功能失效性;基于对新能源控制系统内腔锈蚀研究,形成了企业内部对内腔腐蚀试验的评价指标。
This paper conducted an in-depth study on the internal cavity corrosion of new energy control modules.The paper firstly analyzed the key factors contributing to corrosion in the cooling system cavity of conventional fuel vehicles.Through a plasma concentration orthogonal test,this study simulated the equivalent ion concentration of the cooling medium to identify the influential corrosion factors.Subsequently,by comparing the corrosion rates of aluminum substrates under different corrosive media,this paper demonstrated the applicability of traditional test methods to new energy control systems.A cavity blockage test was designed to verify the functional failure of the cooling system under affected conditions caused by corrosion.Finally,based on the investigation of internal cavity corrosion in new energy control systems,evaluation criteria for conducting internal cavity corrosion test within the company were developed.
