蒸發式冷凝器

蒸(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)是(shi)傳(chuan)(chuan)統的(de)(de)涼水塔(ta)和管(guan)(guan)(guan)(guan)(guan)殼式(shi)冷(leng)(leng)凝(ning)器(qi)的(de)(de)一種組(zu)合改進設備，主要(yao)由(you)換(huan)熱(re)裝置(zhi)、水循環系統及風(feng)(feng)機三部(bu)分組(zu)成，傳(chuan)(chuan)熱(re)部(bu)分多為蛇(she)形管(guan)(guan)(guan)(guan)(guan)組(zu)。制(zhi)(zhi)冷(leng)(leng)劑(ji)(ji)蒸(zheng)汽流(liu)過管(guan)(guan)(guan)(guan)(guan)內，管(guan)(guan)(guan)(guan)(guan)外是(shi)空氣和噴淋水的(de)(de)混合物作為冷(leng)(leng)卻用(yong)流(liu)體。制(zhi)(zhi)冷(leng)(leng)劑(ji)(ji)蒸(zheng)汽由(you)上部(bu)進氣口進入(ru)，在管(guan)(guan)(guan)(guan)(guan)內自上而下逐漸凝(ning)結放出熱(re)量(liang)(liang)，通(tong)過管(guan)(guan)(guan)(guan)(guan)壁(bi)傳(chuan)(chuan)給(gei)管(guan)(guan)(guan)(guan)(guan)外的(de)(de)水膜，再通(tong)過管(guan)(guan)(guan)(guan)(guan)外冷(leng)(leng)卻水的(de)(de)蒸(zheng)發(fa)將熱(re)量(liang)(liang)傳(chuan)(chuan)遞給(gei)空氣也就是(shi)利用(yong)水的(de)(de)汽化熱(re)，帶(dai)走(zou)制(zhi)(zhi)冷(leng)(leng)劑(ji)(ji)冷(leng)(leng)凝(ning)過程放出的(de)(de)冷(leng)(leng)凝(ning)熱(re)量(liang)(liang)蒸(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)的(de)(de)換(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)一般用(yong)光管(guan)(guan)(guan)(guan)(guan)，但隨著對換(huan)熱(re)管(guan)(guan)(guan)(guan)(guan)的(de)(de)不(bu)斷研究，出現了橢(tuo)圓管(guan)(guan)(guan)(guan)(guan)、異形管(guan)(guan)(guan)(guan)(guan)、波紋(wen)管(guan)(guan)(guan)(guan)(guan)和交變(bian)曲面波紋(wen)管(guan)(guan)(guan)(guan)(guan)等新(xin)型盤管(guan)(guan)(guan)(guan)(guan)。噴淋水量(liang)(liang)以(yi)能全部(bu)潤(run)濕盤管(guan)(guan)(guan)(guan)(guan)表面、形成連續水膜為，以(yi)獲得大(da)的(de)(de)傳(chuan)(chuan)熱(re)系數，并減(jian)少水垢(gou)。蒸(zheng)發(fa)式(shi)冷(leng)(leng)凝(ning)器(qi)根(gen)據風(feng)(feng)機安(an)裝的(de)(de)位(wei)置(zhi)不(bu)同(tong)主要(yao)有吸(xi)風(feng)(feng)式(shi)、鼓風(feng)(feng)式(shi)和上吸(xi)風(feng)(feng)橫流(liu)-順(shun)流(liu)式(shi)三種。
