Thermal Analysis and Stress Analysis of the Heat-Exchange Pipe Based on ANSYS

ANSYS to be as a finite element analysis software has powerful features in thermal analysis and structural analysis. Based on ANSYS thermal analysis function, this paper selects SOLID90 unit, for thermal analysis on the heat-exchange pipe of heat exchanger to obtain the temperature distribution, and the temperature calculated will be treated as temperature load, in order to solve the thermal stress by the elasticity method and to get the axial stress distribution of the heat-exchange pipe. According to temperature distribution and stress distribution, this paper puts forward reasonable and economical measures to make the heat-exchange pipe.
