1、-----------------------------------------------------------------------------------------------------------------------------------------------浮頭管殼式換熱器設(shè)計(jì)[摘要]換熱器是用于物體之間進(jìn)行熱量傳遞的過程設(shè)備，使熱量從熱流體傳遞到冷流體的設(shè)備。浮頭式換熱器是針對(duì)固定管板式換熱器在熱補(bǔ)償方面的缺陷進(jìn)行了改進(jìn)的換熱設(shè)備。本設(shè)計(jì)說明書是關(guān)于浮頭式換熱器的設(shè)計(jì)，主要分為說明、計(jì)算和三維建模三部分。說明部分

2、主要敘述了換熱器的特點(diǎn)和分類以及浮頭式換熱器主要零部件結(jié)構(gòu)的設(shè)計(jì)及壓力容器常用材料等；計(jì)算部分主要對(duì)浮頭換熱器的筒體、封頭和法蘭進(jìn)行了詳細(xì)地計(jì)算，并對(duì)其進(jìn)行了強(qiáng)度的校核；三維建模部分是使用UG對(duì)整體和主要零部件的三維建模。[關(guān)鍵字]換熱器設(shè)計(jì)；浮頭式；UG建模；-----------------------------------------------------------------------------------------------------------------------------------------------
