| Abstract: | Longitudinal flow heat exchangers are applied more and more in petroleum and chemical industries,due to their characteristics of having high heat transfer efficiency, lower pressure drop and effectively avoiding fluid induced vibration, etc. The application of efficient heat transfer tubes and the change of tube-bundle\|supporting objects show mainly the development of their structures. This paper illustrates characteristics of longitudinal flow heat exchangers, and introduces the development on structures and performances of the efficient heat transfer tubes and tube\|bundle supporting objects. The development prospect of longitudinal flow heat exchangers are also indicated. |
