蒸發式冷凝器

蒸(zheng)(zheng)發(fa)式(shi)冷凝(ning)(ning)器是傳統(tong)(tong)的涼水(shui)(shui)(shui)(shui)塔(ta)和管(guan)(guan)(guan)殼式(shi)冷凝(ning)(ning)器的一種組(zu)(zu)合(he)改進(jin)(jin)設備，主要由換(huan)熱(re)(re)裝置、水(shui)(shui)(shui)(shui)循(xun)環系(xi)統(tong)(tong)及風機三部分組(zu)(zu)成，傳熱(re)(re)部分多為蛇形(xing)(xing)管(guan)(guan)(guan)組(zu)(zu)。制(zhi)冷劑(ji)蒸(zheng)(zheng)汽流過(guo)管(guan)(guan)(guan)內(nei)，管(guan)(guan)(guan)外(wai)是空氣(qi)和噴(pen)淋水(shui)(shui)(shui)(shui)的混合(he)物作為冷卻(que)(que)用(yong)流體。制(zhi)冷劑(ji)蒸(zheng)(zheng)汽由上(shang)部進(jin)(jin)氣(qi)口進(jin)(jin)入(ru)，在管(guan)(guan)(guan)內(nei)自上(shang)而(er)下(xia)逐(zhu)漸凝(ning)(ning)結放出熱(re)(re)量(liang)，通過(guo)管(guan)(guan)(guan)壁傳給(gei)(gei)管(guan)(guan)(guan)外(wai)的水(shui)(shui)(shui)(shui)膜，再(zai)通過(guo)管(guan)(guan)(guan)外(wai)冷卻(que)(que)水(shui)(shui)(shui)(shui)的蒸(zheng)(zheng)發(fa)將熱(re)(re)量(liang)傳遞給(gei)(gei)空氣(qi)也(ye)就(jiu)是利用(yong)水(shui)(shui)(shui)(shui)的汽化(hua)熱(re)(re)，帶走制(zhi)冷劑(ji)冷凝(ning)(ning)過(guo)程(cheng)放出的冷凝(ning)(ning)熱(re)(re)量(liang)蒸(zheng)(zheng)發(fa)式(shi)冷凝(ning)(ning)器的換(huan)熱(re)(re)管(guan)(guan)(guan)一般用(yong)光(guang)管(guan)(guan)(guan)，但(dan)隨著(zhu)對換(huan)熱(re)(re)管(guan)(guan)(guan)的不(bu)斷(duan)研(yan)究，出現了(le)橢圓管(guan)(guan)(guan)、異形(xing)(xing)管(guan)(guan)(guan)、波紋管(guan)(guan)(guan)和交變曲面(mian)波紋管(guan)(guan)(guan)等新型盤(pan)管(guan)(guan)(guan)。噴(pen)淋水(shui)(shui)(shui)(shui)量(liang)以能(neng)全(quan)部潤濕盤(pan)管(guan)(guan)(guan)表面(mian)、形(xing)(xing)成連(lian)續水(shui)(shui)(shui)(shui)膜為，以獲得大的傳熱(re)(re)系(xi)數，并減少水(shui)(shui)(shui)(shui)垢。蒸(zheng)(zheng)發(fa)式(shi)冷凝(ning)(ning)器根據風機安裝的位(wei)置不(bu)同主要有吸(xi)風式(shi)、鼓風式(shi)和上(shang)吸(xi)風橫流-順流式(shi)三種。
