蒸發式冷凝器

蒸(zheng)(zheng)(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)是(shi)(shi)(shi)傳(chuan)統的(de)(de)涼水(shui)(shui)塔和(he)管(guan)(guan)(guan)(guan)殼式(shi)冷(leng)(leng)凝(ning)器(qi)的(de)(de)一(yi)種(zhong)組(zu)(zu)合改進(jin)設備，主要(yao)由換(huan)熱(re)(re)(re)(re)裝置(zhi)、水(shui)(shui)循環系(xi)統及風(feng)機(ji)三部分組(zu)(zu)成，傳(chuan)熱(re)(re)(re)(re)部分多(duo)為蛇(she)形(xing)管(guan)(guan)(guan)(guan)組(zu)(zu)。制(zhi)冷(leng)(leng)劑(ji)蒸(zheng)(zheng)(zheng)汽流(liu)(liu)過管(guan)(guan)(guan)(guan)內，管(guan)(guan)(guan)(guan)外是(shi)(shi)(shi)空氣和(he)噴淋水(shui)(shui)的(de)(de)混合物作為冷(leng)(leng)卻用流(liu)(liu)體。制(zhi)冷(leng)(leng)劑(ji)蒸(zheng)(zheng)(zheng)汽由上部進(jin)氣口進(jin)入，在管(guan)(guan)(guan)(guan)內自上而下逐漸凝(ning)結放出熱(re)(re)(re)(re)量，通(tong)過管(guan)(guan)(guan)(guan)壁傳(chuan)給管(guan)(guan)(guan)(guan)外的(de)(de)水(shui)(shui)膜(mo)，再通(tong)過管(guan)(guan)(guan)(guan)外冷(leng)(leng)卻水(shui)(shui)的(de)(de)蒸(zheng)(zheng)(zheng)發(fa)將熱(re)(re)(re)(re)量傳(chuan)遞(di)給空氣也就(jiu)是(shi)(shi)(shi)利用水(shui)(shui)的(de)(de)汽化熱(re)(re)(re)(re)，帶走制(zhi)冷(leng)(leng)劑(ji)冷(leng)(leng)凝(ning)過程放出的(de)(de)冷(leng)(leng)凝(ning)熱(re)(re)(re)(re)量蒸(zheng)(zheng)(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)的(de)(de)換(huan)熱(re)(re)(re)(re)管(guan)(guan)(guan)(guan)一(yi)般用光管(guan)(guan)(guan)(guan)，但隨著(zhu)對換(huan)熱(re)(re)(re)(re)管(guan)(guan)(guan)(guan)的(de)(de)不斷研究，出現了橢圓管(guan)(guan)(guan)(guan)、異形(xing)管(guan)(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)(guan)和(he)交變曲(qu)面(mian)波(bo)紋管(guan)(guan)(guan)(guan)等新型盤(pan)管(guan)(guan)(guan)(guan)。噴淋水(shui)(shui)量以能全部潤濕(shi)盤(pan)管(guan)(guan)(guan)(guan)表面(mian)、形(xing)成連續水(shui)(shui)膜(mo)為，以獲得大的(de)(de)傳(chuan)熱(re)(re)(re)(re)系(xi)數，并減(jian)少水(shui)(shui)垢(gou)。蒸(zheng)(zheng)(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)根據風(feng)機(ji)安(an)裝的(de)(de)位置(zhi)不同(tong)主要(yao)有吸風(feng)式(shi)、鼓風(feng)式(shi)和(he)上吸風(feng)橫流(liu)(liu)-順(shun)流(liu)(liu)式(shi)三種(zhong)。
