The heat exchanger model is established by arranging regular triangles,among which the shell diameter is 325 mm,the heat exchange tube specifications are φ25 mm×2.5 mm,The length is 2 000 mm,the number is 52,and the baffle spacing is 220 mm.The heat load,the average temperature difference of heat transfer,the heat transfer area,and the amount of circulating water are obtained by calculating the heat transfer of the cold fluid(circulating water)and the hot fluid(chlorobenzene)in the heat exchanger.The temperature field,velocity field and wall lifting distance of E-type,F-type and J-type shell heat exchangers are analyzed through simulation analysis,and the results show that the temperature difference,flow rate and heat exchange of E-type shell heat exchangers are optimal.This paper provides a reference for the structural design of the heat exchanger.
