style="text-indent:25px">管殼式換熱器中，殼程通常是一個(gè)薄弱環(huán)節(jié)。通常普通的弓形折流板能造成曲折的流道系統(tǒng)(z字形流道)，這樣會(huì)導(dǎo)致較大的死角和相對(duì)高的返混。而這些死角又能造成殼程結(jié)垢加劇，對(duì)傳熱效率不利。返混也能使平均溫差失真和縮小。其后果是，與活塞流相比，弓形折流板會(huì)降低凈傳熱。優(yōu)越弓形折流板管殼式換熱器很難滿足高熱效率的要求，故常為其他型式的換熱器所取代(如緊湊型板式換熱器)。對(duì)普通折流板幾何形狀的改進(jìn)，是發(fā)展殼程的第一步。雖然引進(jìn)了密封條和附加諸如偏轉(zhuǎn)折流板及采取其他措施來(lái)改進(jìn)換熱器的性能，但普通折流板設(shè)計(jì)的主要缺點(diǎn)依然存在。濟(jì)南換熱器廠家價(jià)格</p><p
