【Abstract】 Based on the numerical simulation result of convective heat transfer,the finite element calculating model of the integrate jacket structure of the cylinder of a thin film evaporator was established,the stress analysis and the intensity calculation of the structure were made using the finite element method. The result shows that the structure was safe when the temperature load was not in consideration; the structure was not safe when the temperature load was in consideration. The structure design was improved,and the corresponding intensity calculation was made,they were successful in practice.更多还原
