【Abstract】 The fixed tube-sheet heat exchanger, worked on the condition of high temperature and high pressure, has been the finite elemental analysis of the thermal and the structural stress. Analyzed and compared with the highest stress of the three kinds of operation modes, obtains temperature is the main factor generated the high stress in it.更多还原
