在(zai)(zai)電(dian)(dian)(dian)(dian)鍍生(sheng)產(chan)(chan)(chan)中，電(dian)(dian)(dian)(dian)鍍液在(zai)(zai)電(dian)(dian)(dian)(dian)鍍反應中產(chan)(chan)(chan)生(sheng)的(de)(de)熱量使電(dian)(dian)(dian)(dian)鍍液的(de)(de)溫度(du)(du)升高。當電(dian)(dian)(dian)(dian)鍍液溫度(du)(du)高于工業(ye)(ye)生(sheng)產(chan)(chan)(chan)要求時，對工業(ye)(ye)生(sheng)產(chan)(chan)(chan)的(de)(de)電(dian)(dian)(dian)(dian)鍍產(chan)(chan)(chan)品的(de)(de)牢(lao)固度(du)(du)、均勻(yun)度(du)(du)、平整度(du)(du)和表(biao)面光(guang)潔度(du)(du)有(you)很(hen)大影響(xiang)。如(ru)果冷(leng)水機提供的(de)(de)冷(leng)凍電(dian)(dian)(dian)(dian)子元(yuan)(yuan)件的(de)(de)生(sheng)產(chan)(chan)(chan)過程需要將基本元(yuan)(yuan)件保持或冷(leng)卻(que)在(zai)(zai)特定(ding)的(de)(de)溫度(du)(du)，則可以在(zai)(zai)設計狀態下控制電(dian)(dian)(dian)(dian)子元(yuan)(yuan)件的(de)(de)性(xing)能參數(shu)。采(cai)用水冷(leng)卻(que)和保持電(dian)(dian)(dian)(dian)鍍液的(de)(de)恒溫，大大提高了電(dian)(dian)(dian)(dian)鍍的(de)(de)工業(ye)(ye)化(hua)生(sheng)產(chan)(chan)(chan)和生(sheng)產(chan)(chan)(chan)效(xiao)率，因為電(dian)(dian)(dian)(dian)鍍行業(ye)(ye)具(ju)有(you)很(hen)強的(de)(de)腐蝕性(xing)。冷(leng)卻(que)方式可分為直接冷(leng)卻(que)和間接冷(leng)卻(que)：

i直(zhi)接(jie)冷(leng)卻(que)：即鍍(du)液通過過濾器(qi)(qi)或濾網直(zhi)接(jie)進(jin)入制冷(leng)機(ji)的(de)蒸發器(qi)(qi)進(jin)行冷(leng)卻(que)，然后返回氧化(hua)槽(cao)。這種(zhong)冷(leng)卻(que)方式(shi)的(de)優缺點(dian)(dian)：冷(leng)卻(que)時(shi)間短(duan)，效果好(hao)；缺點(dian)(dian)是蒸發器(qi)(qi)需(xu)要防腐處理（一般采用鈦合金）。蒸發器(qi)(qi)容易結(jie)垢，需(xu)要定期清(qing)洗，否則會影響(xiang)冷(leng)卻(que)效果和(he)機(ji)器(qi)(qi)運行。

間接冷(leng)(leng)卻(que)：氧化槽(cao)內鋪設鈦管(guan)，冷(leng)(leng)凍水(shui)通過鈦管(guan)帶走輸送液(ye)的(de)熱量(liang)，達到冷(leng)(leng)卻(que)的(de)目的(de)；如(ru)果不方便(bian)鋪設鈦管(guan)，可加(jia)熱交換器(qi)（鈦合金材(cai)質），走冷(leng)(leng)卻(que)水(shui)和鍍(du)液(ye)

綜上所述，冷(leng)(leng)水機直接冷(leng)(leng)凍和間接冷(leng)(leng)凍有很多(duo)相似之處，但直接冷(leng)(leng)凍冷(leng)(leng)水機不如間接冷(leng)(leng)凍冷(leng)(leng)水機安全，而(er)且(qie)前者容易腐蝕，壽命(ming)短。
