蒸發式冷凝器

蒸(zheng)發式(shi)冷(leng)(leng)凝(ning)(ning)器(qi)是傳(chuan)統的(de)涼水(shui)(shui)塔(ta)和管(guan)(guan)(guan)殼式(shi)冷(leng)(leng)凝(ning)(ning)器(qi)的(de)一(yi)種(zhong)組(zu)合改(gai)進設備，主(zhu)要由換(huan)熱(re)(re)裝(zhuang)置、水(shui)(shui)循環(huan)系(xi)統及(ji)風(feng)(feng)(feng)機三部分組(zu)成(cheng)，傳(chuan)熱(re)(re)部分多(duo)為蛇形(xing)管(guan)(guan)(guan)組(zu)。制冷(leng)(leng)劑(ji)蒸(zheng)汽流過(guo)管(guan)(guan)(guan)內(nei)(nei)，管(guan)(guan)(guan)外(wai)是空氣(qi)(qi)和噴淋水(shui)(shui)的(de)混合物作為冷(leng)(leng)卻(que)用流體。制冷(leng)(leng)劑(ji)蒸(zheng)汽由上(shang)部進氣(qi)(qi)口(kou)進入，在管(guan)(guan)(guan)內(nei)(nei)自上(shang)而(er)下逐漸凝(ning)(ning)結放出熱(re)(re)量(liang)，通過(guo)管(guan)(guan)(guan)壁傳(chuan)給(gei)管(guan)(guan)(guan)外(wai)的(de)水(shui)(shui)膜(mo)，再通過(guo)管(guan)(guan)(guan)外(wai)冷(leng)(leng)卻(que)水(shui)(shui)的(de)蒸(zheng)發將熱(re)(re)量(liang)傳(chuan)遞給(gei)空氣(qi)(qi)也就是利(li)用水(shui)(shui)的(de)汽化熱(re)(re)，帶走制冷(leng)(leng)劑(ji)冷(leng)(leng)凝(ning)(ning)過(guo)程放出的(de)冷(leng)(leng)凝(ning)(ning)熱(re)(re)量(liang)蒸(zheng)發式(shi)冷(leng)(leng)凝(ning)(ning)器(qi)的(de)換(huan)熱(re)(re)管(guan)(guan)(guan)一(yi)般用光管(guan)(guan)(guan)，但隨著對(dui)換(huan)熱(re)(re)管(guan)(guan)(guan)的(de)不斷研究，出現了橢圓管(guan)(guan)(guan)、異(yi)形(xing)管(guan)(guan)(guan)、波(bo)紋管(guan)(guan)(guan)和交變曲(qu)面波(bo)紋管(guan)(guan)(guan)等新型盤管(guan)(guan)(guan)。噴淋水(shui)(shui)量(liang)以能全部潤濕盤管(guan)(guan)(guan)表(biao)面、形(xing)成(cheng)連(lian)續水(shui)(shui)膜(mo)為，以獲(huo)得大(da)的(de)傳(chuan)熱(re)(re)系(xi)數，并減少(shao)水(shui)(shui)垢。蒸(zheng)發式(shi)冷(leng)(leng)凝(ning)(ning)器(qi)根據風(feng)(feng)(feng)機安裝(zhuang)的(de)位(wei)置不同(tong)主(zhu)要有(you)吸(xi)風(feng)(feng)(feng)式(shi)、鼓風(feng)(feng)(feng)式(shi)和上(shang)吸(xi)風(feng)(feng)(feng)橫流-順流式(shi)三種(zhong)。
