翅片(pian)式換熱器是氣體(ti)與(yu)液體(ti)熱交換器中使用最為(wei)廣泛(fan)的一種換熱設備。

   它(ta)通(tong)過在(zai)普(pu)通(tong)的基管(guan)(guan)(guan)上(shang)加裝翅(chi)片(pian)來達到強化(hua)傳熱(re)的目(mu)的。翅(chi)片(pian)式(shi)換(huan)熱(re)器單位換(huan)熱(re)面(mian)積是(shi)普(pu)通(tong)裸管(guan)(guan)(guan)的十幾(ji)倍，因為(wei)具有(you)體積小(xiao)，結構緊湊，重(zhong)量(liang)輕，占地面(mian)積小(xiao)等(deng)優(you)點(dian)。廣(guang)泛應用(yong)于(yu)各(ge)種烘干設(she)備上(shang)，合理的風速設(she)計可(ke)以(yi)讓換(huan)熱(re)效(xiao)果(guo)達到最佳干燥狀態。采用(yong)蒸汽和導(dao)熱(re)油(you)作為(wei)熱(re)源，基管(guan)(guan)(guan)可(ke)以(yi)用(yong)鋼管(guan)(guan)(guan)；不銹鋼管(guan)(guan)(guan)；銅管(guan)(guan)(guan)等(deng)。翅(chi)片(pian)也可(ke)以(yi)用(yong)鋼帶；不銹鋼帶，銅帶，鋁帶等(deng)。　

    翅(chi)片(pian)式(shi)(shi)換(huan)熱器在翅(chi)片(pian)結構形式(shi)(shi)上可分為繞片(pian)式(shi)(shi)；串(chuan)片(pian)式(shi)(shi)；焊片(pian)式(shi)(shi)；軋片(pian)式(shi)(shi)。
