在(zai)電(dian)(dian)(dian)(dian)鍍(du)(du)生產(chan)(chan)中，電(dian)(dian)(dian)(dian)鍍(du)(du)液(ye)在(zai)電(dian)(dian)(dian)(dian)鍍(du)(du)反應中產(chan)(chan)生的(de)熱量(liang)使電(dian)(dian)(dian)(dian)鍍(du)(du)液(ye)的(de)溫度(du)升高(gao)。當(dang)電(dian)(dian)(dian)(dian)鍍(du)(du)液(ye)溫度(du)高(gao)于工業生產(chan)(chan)要求時，對工業生產(chan)(chan)的(de)電(dian)(dian)(dian)(dian)鍍(du)(du)產(chan)(chan)品(pin)的(de)牢固度(du)、均勻度(du)、平整(zheng)度(du)和表面(mian)光潔度(du)有(you)很大影響。如果冷水(shui)機(ji)提供的(de)冷凍電(dian)(dian)(dian)(dian)子元(yuan)件的(de)生產(chan)(chan)過程需要將基本(ben)元(yuan)件保持或冷卻(que)(que)在(zai)特定(ding)的(de)溫度(du)，則(ze)可以在(zai)設計狀(zhuang)態下(xia)控制電(dian)(dian)(dian)(dian)子元(yuan)件的(de)性(xing)能參數。采用水(shui)冷卻(que)(que)和保持電(dian)(dian)(dian)(dian)鍍(du)(du)液(ye)的(de)恒溫，大大提高(gao)了(le)電(dian)(dian)(dian)(dian)鍍(du)(du)的(de)工業化(hua)生產(chan)(chan)和生產(chan)(chan)效率，因為(wei)電(dian)(dian)(dian)(dian)鍍(du)(du)行業具有(you)很強的(de)腐蝕性(xing)。冷卻(que)(que)方式可分為(wei)直接冷卻(que)(que)和間接冷卻(que)(que)：

i直(zhi)接冷(leng)(leng)(leng)卻(que)：即鍍液通過過濾器(qi)(qi)或濾網(wang)直(zhi)接進入制冷(leng)(leng)(leng)機的蒸(zheng)發(fa)(fa)器(qi)(qi)進行(xing)冷(leng)(leng)(leng)卻(que)，然后返回氧化(hua)槽。這種(zhong)冷(leng)(leng)(leng)卻(que)方(fang)式(shi)的優缺點(dian)：冷(leng)(leng)(leng)卻(que)時間短(duan)，效果好；缺點(dian)是蒸(zheng)發(fa)(fa)器(qi)(qi)需要防腐(fu)處理（一(yi)般采(cai)用(yong)鈦合金）。蒸(zheng)發(fa)(fa)器(qi)(qi)容(rong)易結垢，需要定期(qi)清洗，否(fou)則會影(ying)響冷(leng)(leng)(leng)卻(que)效果和機器(qi)(qi)運行(xing)。

間接冷(leng)(leng)(leng)卻：氧(yang)化槽內鋪設鈦(tai)管(guan)，冷(leng)(leng)(leng)凍水通過鈦(tai)管(guan)帶走輸送液(ye)的熱量，達到(dao)冷(leng)(leng)(leng)卻的目(mu)的；如果(guo)不方便鋪設鈦(tai)管(guan)，可加熱交(jiao)換器(qi)（鈦(tai)合(he)金材質），走冷(leng)(leng)(leng)卻水和(he)鍍液(ye)

綜上(shang)所述(shu)，冷(leng)水(shui)機(ji)直(zhi)(zhi)接(jie)冷(leng)凍(dong)和間(jian)接(jie)冷(leng)凍(dong)有很(hen)多相似之處，但直(zhi)(zhi)接(jie)冷(leng)凍(dong)冷(leng)水(shui)機(ji)不如間(jian)接(jie)冷(leng)凍(dong)冷(leng)水(shui)機(ji)安全，而且(qie)前者容(rong)易腐蝕，壽命(ming)短。
