Analysis on the leakage of the heat pipe of the automobile radiator
摘要
Abstract
In view of the leakage failure of a heat sink cooling pipe,a finite element analysis method is used to analyze the dynamic stress of the radiator.Using CATIA to establish three-dimensional model of the radiator,the heat sink finite element model is built in HyperMesh,and the correctness of the finite element model is verified by modal test,and the dynamic response of RADIOSS is used to solve the model.The research shows that the position of the maximum stress in the heat sink cooling pipe is in accord with the actual leakage point of the fault radiator,and the failure of the radiator cooling pipe is due to the stress caused by the vibration of the heat sink.Through the improvement of the original structure of the radiator,the maximum stress of the radiator cooling tube is decreased by 42％,and the service life of the radiator is improved.关键词
