管壳式换热器设计要点综述

Design Points Review of Shell & Tube Heat Exchanger

管壳式换热器属于多腔容器,且因含管板计算,因此设计复杂。文中通过对管壳式换热器设计要点分类分析,对一些不容易把握的设计问题,提出了建议。文中提出的问题,均来自多年的设计案例。文中还简要介绍了引进设备设计改造的注意事项。文中示例有助于对设计所涉及问题的处置。

A shell and tube heat exchanger is a multi-cavity container. Because it covers tube sheet calculation, the design is complex. Through an analysis of the classifications of the design points of the shell and tube heat exchanger, this paper brings forward its viewpoints and suggestions on how to deal with problems uncertain during the design work. The questions raised in this paper are from years of design practice and this will improve the designers＇ understanding in application of the standards. Matters calling for attention to the modification of the imported equipment are also outlined. The illustrative examples raised in this work will enehanee the response to and disposal of the problems related to the design.
