Title:: Discussion on the design parameters of tubular fluoro-plastic heat exchanger by computer calculation and FORTRAN program

摘要:: 氟塑换热器中采用聚四氟乙烯为材质的换热管束,在设计中除了要进行一般管式换热器的常规计算外,还要考虑到为数众多的管子在管板上的排列及 F-4管板限胀施压加热焊接的工艺要求。为此设计了这一数模及计算程序,主要解决管数、换热面、管束内总流截面、F-4管板最小直径等相互关系的繁琐数据计算,最终得到所需的某一范围内的函数表,大大简化了设计工作。

Abstract:: Fluoro-plastic heat exchanger adopts polytetrafluoron as the material of heat exchange tube bundle, in addition to the general calculation of tube heat exchanger in the design, but also consider the arrangement of a large number of tubes on the tube plate and F-4 tube plate limited expansion pressure heating welding process requirements.For this reason, the numerical model and calculation program are designed, which mainly solve the complicated data calculation of the relationship between the number of tubes, heat exchange surface, the total flow section in the tube bundle and the minimum diameter of the F-4 tube plate, and finally get the required function table in a certain range, which greatly simplifies the design work.
