板壳式换热器设置膨胀节的判定

Method for Determining Necessity of Expansion Joint in Plate-Shell Heat Exchangers

介绍板壳式换热器的主要特点和应用。当壳体与板束温差较大时,笔者通过对产品开发的生产实践,提出解决板壳式换热器要否设置膨胀节的类似判定方法。

Main characters and applications of plate-shell-heat exchangers are introduced in this paper. Through the practice of developing the products, some experience is available which can be used to determine in which case the expansion joint is necessary in plate-shell exchangers.
