蒸發式冷凝器

蒸(zheng)發(fa)式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器(qi)是傳(chuan)(chuan)統(tong)的(de)(de)(de)(de)(de)涼(liang)水塔(ta)和管(guan)(guan)(guan)(guan)(guan)殼式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器(qi)的(de)(de)(de)(de)(de)一(yi)種組(zu)合改進(jin)(jin)設(she)備，主要由換熱(re)(re)(re)裝置、水循(xun)環(huan)系(xi)統(tong)及風機(ji)三部分組(zu)成，傳(chuan)(chuan)熱(re)(re)(re)部分多為蛇(she)形管(guan)(guan)(guan)(guan)(guan)組(zu)。制冷(leng)(leng)(leng)劑(ji)蒸(zheng)汽流(liu)過(guo)(guo)管(guan)(guan)(guan)(guan)(guan)內，管(guan)(guan)(guan)(guan)(guan)外是空氣(qi)和噴淋水的(de)(de)(de)(de)(de)混合物(wu)作為冷(leng)(leng)(leng)卻用流(liu)體。制冷(leng)(leng)(leng)劑(ji)蒸(zheng)汽由上部進(jin)(jin)氣(qi)口進(jin)(jin)入，在管(guan)(guan)(guan)(guan)(guan)內自上而(er)下逐(zhu)漸(jian)凝(ning)(ning)結放出(chu)熱(re)(re)(re)量，通過(guo)(guo)管(guan)(guan)(guan)(guan)(guan)壁傳(chuan)(chuan)給(gei)管(guan)(guan)(guan)(guan)(guan)外的(de)(de)(de)(de)(de)水膜(mo)，再通過(guo)(guo)管(guan)(guan)(guan)(guan)(guan)外冷(leng)(leng)(leng)卻水的(de)(de)(de)(de)(de)蒸(zheng)發(fa)將熱(re)(re)(re)量傳(chuan)(chuan)遞給(gei)空氣(qi)也就是利(li)用水的(de)(de)(de)(de)(de)汽化(hua)熱(re)(re)(re)，帶(dai)走(zou)制冷(leng)(leng)(leng)劑(ji)冷(leng)(leng)(leng)凝(ning)(ning)過(guo)(guo)程放出(chu)的(de)(de)(de)(de)(de)冷(leng)(leng)(leng)凝(ning)(ning)熱(re)(re)(re)量蒸(zheng)發(fa)式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器(qi)的(de)(de)(de)(de)(de)換熱(re)(re)(re)管(guan)(guan)(guan)(guan)(guan)一(yi)般(ban)用光管(guan)(guan)(guan)(guan)(guan)，但隨著對換熱(re)(re)(re)管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)不(bu)(bu)斷研(yan)究，出(chu)現了(le)橢圓管(guan)(guan)(guan)(guan)(guan)、異形管(guan)(guan)(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)(guan)(guan)和交變曲面波(bo)紋管(guan)(guan)(guan)(guan)(guan)等新型盤管(guan)(guan)(guan)(guan)(guan)。噴淋水量以能全部潤濕(shi)盤管(guan)(guan)(guan)(guan)(guan)表面、形成連續水膜(mo)為，以獲得大的(de)(de)(de)(de)(de)傳(chuan)(chuan)熱(re)(re)(re)系(xi)數(shu)，并減少水垢。蒸(zheng)發(fa)式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器(qi)根據風機(ji)安裝的(de)(de)(de)(de)(de)位置不(bu)(bu)同主要有(you)吸風式(shi)(shi)、鼓(gu)風式(shi)(shi)和上吸風橫流(liu)-順流(liu)式(shi)(shi)三種。
