摘要：This paper analyses the thermal stress of multi-Tube heat exchanger with spirally corrugated tubes using numerical simulations. The simulations are focused on the thermal stress of the tube bundle and tube plate, which have large temperature difference. In this paper, the heat exchanger design software HTRI is creatively used to calculated the temperature boundary conditions of the heat exchanger, which is difficult to obtain. Based on the indirect coupling method of ANSYS, the thermal stress intensity and thermal deformation between the tube bundle and the tube plate of the heat exchanger are caculated. And the calculation results can provide important references for the design and optimization of the heat exchanger. ? Published under licence by IOP Publishing Ltd.
