换热器分程隔板槽面积的计算

Calculation of Range Partition Slot Area in Heat Exchanger

换热器管板计算中隔板槽面积对管板的强度计算起着很大的作用,GB151-1999《管壳式换热器》中仅给出二管程管板的正三角形排列和正方形排列的计算公式,本文将对二管程管板的转角三角形排列和转角正方形排列,四管程的正三角形排列,四管程的正方形排列,四管程的转角三角形排列,四管程的转角正方形排列的计算公式进行推导,以便压力容器设计者计算的时候参考。

In the heat exchanger tube plate calculation,diaphragm slot area plays a big role in tubesheet strength calculation,GB151-1999 ＂tube shell heat exchanger＂ only gives the calculation formula for double tube side tube plate with regular triangle arrangement or square arrangement.In the paper,calculation formulae for the double tube side tube plate angle triangle arrangement and angle square arrangement,four tube side regular triangle arrangement,four tube side square array,four tube side angle triangle arrangement,four tube side corner square arrangement were deduced in order to provide references for pressure vessel design.
