| Abstract: | Using finite element analysis software ANSYS, analyzed the stress intensity of a fixed tube-sheet heat exchanger under mechanical and temperature loads, assessed the stress and checked the stress intensity of its dangerous section. Indicated that stress analysis of the heat exchanger should include analysis for different dangerous working conditions, and different dangerous parts should be analyzed and evaluated to ensure its safe and reliable operation. |
