蒸發式冷凝器

蒸(zheng)(zheng)發式(shi)(shi)冷(leng)(leng)凝(ning)(ning)器(qi)是傳(chuan)(chuan)統的(de)(de)涼水(shui)(shui)塔和(he)(he)管(guan)(guan)(guan)(guan)殼式(shi)(shi)冷(leng)(leng)凝(ning)(ning)器(qi)的(de)(de)一(yi)種組合(he)改進(jin)設備，主(zhu)要由換熱(re)(re)(re)裝置、水(shui)(shui)循環(huan)系(xi)統及(ji)風機(ji)三部分(fen)組成，傳(chuan)(chuan)熱(re)(re)(re)部分(fen)多為蛇形(xing)管(guan)(guan)(guan)(guan)組。制(zhi)冷(leng)(leng)劑(ji)蒸(zheng)(zheng)汽流過(guo)管(guan)(guan)(guan)(guan)內(nei)，管(guan)(guan)(guan)(guan)外(wai)是空氣(qi)(qi)和(he)(he)噴淋水(shui)(shui)的(de)(de)混合(he)物作(zuo)為冷(leng)(leng)卻用流體。制(zhi)冷(leng)(leng)劑(ji)蒸(zheng)(zheng)汽由上部進(jin)氣(qi)(qi)口(kou)進(jin)入，在(zai)管(guan)(guan)(guan)(guan)內(nei)自上而(er)下逐漸凝(ning)(ning)結放出熱(re)(re)(re)量(liang)，通(tong)過(guo)管(guan)(guan)(guan)(guan)壁傳(chuan)(chuan)給管(guan)(guan)(guan)(guan)外(wai)的(de)(de)水(shui)(shui)膜，再通(tong)過(guo)管(guan)(guan)(guan)(guan)外(wai)冷(leng)(leng)卻水(shui)(shui)的(de)(de)蒸(zheng)(zheng)發將熱(re)(re)(re)量(liang)傳(chuan)(chuan)遞(di)給空氣(qi)(qi)也(ye)就(jiu)是利用水(shui)(shui)的(de)(de)汽化熱(re)(re)(re)，帶走(zou)制(zhi)冷(leng)(leng)劑(ji)冷(leng)(leng)凝(ning)(ning)過(guo)程放出的(de)(de)冷(leng)(leng)凝(ning)(ning)熱(re)(re)(re)量(liang)蒸(zheng)(zheng)發式(shi)(shi)冷(leng)(leng)凝(ning)(ning)器(qi)的(de)(de)換熱(re)(re)(re)管(guan)(guan)(guan)(guan)一(yi)般用光管(guan)(guan)(guan)(guan)，但隨著對換熱(re)(re)(re)管(guan)(guan)(guan)(guan)的(de)(de)不斷(duan)研究，出現了橢圓(yuan)管(guan)(guan)(guan)(guan)、異形(xing)管(guan)(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)(guan)和(he)(he)交變曲面波(bo)紋管(guan)(guan)(guan)(guan)等新型(xing)盤管(guan)(guan)(guan)(guan)。噴淋水(shui)(shui)量(liang)以能全部潤濕盤管(guan)(guan)(guan)(guan)表面、形(xing)成連(lian)續水(shui)(shui)膜為，以獲得大的(de)(de)傳(chuan)(chuan)熱(re)(re)(re)系(xi)數，并減少水(shui)(shui)垢。蒸(zheng)(zheng)發式(shi)(shi)冷(leng)(leng)凝(ning)(ning)器(qi)根(gen)據風機(ji)安裝的(de)(de)位置不同主(zhu)要有(you)吸風式(shi)(shi)、鼓風式(shi)(shi)和(he)(he)上吸風橫流-順流式(shi)(shi)三種。
