蒸發式冷凝器

蒸發式(shi)(shi)冷(leng)(leng)(leng)凝器是傳統的(de)涼水(shui)(shui)塔和管(guan)(guan)(guan)(guan)(guan)殼式(shi)(shi)冷(leng)(leng)(leng)凝器的(de)一種(zhong)組(zu)合(he)改進設備，主要由換熱(re)(re)裝(zhuang)置、水(shui)(shui)循環系統及風(feng)機(ji)三(san)部(bu)(bu)分組(zu)成，傳熱(re)(re)部(bu)(bu)分多為(wei)蛇形(xing)(xing)管(guan)(guan)(guan)(guan)(guan)組(zu)。制(zhi)冷(leng)(leng)(leng)劑蒸汽(qi)流過管(guan)(guan)(guan)(guan)(guan)內，管(guan)(guan)(guan)(guan)(guan)外(wai)是空氣和噴淋水(shui)(shui)的(de)混合(he)物作為(wei)冷(leng)(leng)(leng)卻用流體。制(zhi)冷(leng)(leng)(leng)劑蒸汽(qi)由上(shang)部(bu)(bu)進氣口進入，在管(guan)(guan)(guan)(guan)(guan)內自上(shang)而下逐漸(jian)凝結放出熱(re)(re)量，通(tong)過管(guan)(guan)(guan)(guan)(guan)壁傳給(gei)管(guan)(guan)(guan)(guan)(guan)外(wai)的(de)水(shui)(shui)膜，再通(tong)過管(guan)(guan)(guan)(guan)(guan)外(wai)冷(leng)(leng)(leng)卻水(shui)(shui)的(de)蒸發將熱(re)(re)量傳遞(di)給(gei)空氣也(ye)就是利(li)用水(shui)(shui)的(de)汽(qi)化熱(re)(re)，帶走制(zhi)冷(leng)(leng)(leng)劑冷(leng)(leng)(leng)凝過程(cheng)放出的(de)冷(leng)(leng)(leng)凝熱(re)(re)量蒸發式(shi)(shi)冷(leng)(leng)(leng)凝器的(de)換熱(re)(re)管(guan)(guan)(guan)(guan)(guan)一般用光管(guan)(guan)(guan)(guan)(guan)，但(dan)隨(sui)著對換熱(re)(re)管(guan)(guan)(guan)(guan)(guan)的(de)不(bu)斷研(yan)究，出現了橢圓管(guan)(guan)(guan)(guan)(guan)、異(yi)形(xing)(xing)管(guan)(guan)(guan)(guan)(guan)、波紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)和交變曲面波紋(wen)(wen)管(guan)(guan)(guan)(guan)(guan)等新型盤管(guan)(guan)(guan)(guan)(guan)。噴淋水(shui)(shui)量以(yi)能(neng)全部(bu)(bu)潤濕盤管(guan)(guan)(guan)(guan)(guan)表面、形(xing)(xing)成連續水(shui)(shui)膜為(wei)，以(yi)獲得大的(de)傳熱(re)(re)系數，并減(jian)少水(shui)(shui)垢。蒸發式(shi)(shi)冷(leng)(leng)(leng)凝器根據風(feng)機(ji)安(an)裝(zhuang)的(de)位置不(bu)同主要有吸風(feng)式(shi)(shi)、鼓風(feng)式(shi)(shi)和上(shang)吸風(feng)橫流-順流式(shi)(shi)三(san)種(zhong)。
