摘　　要：为了给镍基渗层纵肋管束式换热器设计和生产中碰到的问题提供一些依据 ,本文在实验的基础上对镍基渗层纵肋管束的换热和流阻特性进行了分析 ,得出肋管结构参数和管束结构参数对换热和流阻的影响On the basis of simulating experiments to provide some foundations for the design of heat exchanger with longitudinally finned banks and for solving the problems on operation, the heat transfer and pressure drop characteristics of cross flow tube banks equipped with longitudinal and rectangular fins in Ni based implanted tube are investigated, and the influence of fin length and tube pitch is analyzed. The minumum entropy optimization is used in evaluating the thermodynamic performance, and the optimizing length of fins is discussed.
