蒸發式冷凝器

蒸發式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器是傳統的涼水(shui)(shui)(shui)塔和(he)(he)管(guan)(guan)(guan)殼(ke)式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器的一(yi)種組(zu)合(he)改進(jin)設備，主要(yao)由(you)換(huan)(huan)熱(re)裝置、水(shui)(shui)(shui)循環系統及風(feng)機三(san)部(bu)分組(zu)成(cheng)，傳熱(re)部(bu)分多為(wei)(wei)蛇形(xing)管(guan)(guan)(guan)組(zu)。制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)蒸汽(qi)流(liu)過(guo)(guo)管(guan)(guan)(guan)內(nei)(nei)，管(guan)(guan)(guan)外(wai)是空(kong)(kong)氣(qi)和(he)(he)噴淋(lin)水(shui)(shui)(shui)的混合(he)物(wu)作(zuo)為(wei)(wei)冷(leng)(leng)(leng)卻用流(liu)體。制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)蒸汽(qi)由(you)上(shang)部(bu)進(jin)氣(qi)口進(jin)入，在管(guan)(guan)(guan)內(nei)(nei)自(zi)上(shang)而下逐(zhu)漸凝(ning)(ning)結放出熱(re)量(liang)，通(tong)過(guo)(guo)管(guan)(guan)(guan)壁傳給管(guan)(guan)(guan)外(wai)的水(shui)(shui)(shui)膜(mo)，再通(tong)過(guo)(guo)管(guan)(guan)(guan)外(wai)冷(leng)(leng)(leng)卻水(shui)(shui)(shui)的蒸發將熱(re)量(liang)傳遞給空(kong)(kong)氣(qi)也就是利(li)用水(shui)(shui)(shui)的汽(qi)化熱(re)，帶(dai)走制(zhi)(zhi)冷(leng)(leng)(leng)劑(ji)冷(leng)(leng)(leng)凝(ning)(ning)過(guo)(guo)程放出的冷(leng)(leng)(leng)凝(ning)(ning)熱(re)量(liang)蒸發式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器的換(huan)(huan)熱(re)管(guan)(guan)(guan)一(yi)般用光管(guan)(guan)(guan)，但隨著對換(huan)(huan)熱(re)管(guan)(guan)(guan)的不斷研究，出現了(le)橢圓管(guan)(guan)(guan)、異形(xing)管(guan)(guan)(guan)、波紋管(guan)(guan)(guan)和(he)(he)交變曲面波紋管(guan)(guan)(guan)等(deng)新(xin)型(xing)盤(pan)管(guan)(guan)(guan)。噴淋(lin)水(shui)(shui)(shui)量(liang)以能全部(bu)潤(run)濕盤(pan)管(guan)(guan)(guan)表(biao)面、形(xing)成(cheng)連續水(shui)(shui)(shui)膜(mo)為(wei)(wei)，以獲得大的傳熱(re)系數，并減少水(shui)(shui)(shui)垢。蒸發式(shi)(shi)冷(leng)(leng)(leng)凝(ning)(ning)器根據風(feng)機安(an)裝的位置不同主要(yao)有吸風(feng)式(shi)(shi)、鼓風(feng)式(shi)(shi)和(he)(he)上(shang)吸風(feng)橫(heng)流(liu)-順流(liu)式(shi)(shi)三(san)種。
