可以預(yù)計(jì)，氣動(dòng)噴涂法在緊湊***換熱器的生產(chǎn)中，將會(huì)得到***應(yīng)用。折疊螺旋折流在管殼式換熱器中，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***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。為此，美國(guó)提出了一種新方案，即建議采用螺旋狀折流板。這種設(shè)計(jì)的先進(jìn)性已為流體動(dòng)力學(xué)研究和傳熱試驗(yàn)結(jié)果所證實(shí)，此設(shè)計(jì)已獲得專利權(quán)。此種結(jié)構(gòu)克服了普通折流板的主要缺點(diǎn)。螺旋折流板的設(shè)計(jì)原理很簡(jiǎn)單：將圓截面的特制板安裝在“擬螺旋折流系統(tǒng)”中，每塊折流板占換熱器殼程中橫剖面的四分之一，其傾角朝向換熱器的軸線，即與換熱器軸線保持一傾斜度。相鄰折流板的周邊相接，與外圓處成連續(xù)螺旋狀。折流板的軸向重疊。</p><p>
