在(zai)電(dian)(dian)(dian)鍍(du)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)中，電(dian)(dian)(dian)鍍(du)液(ye)(ye)在(zai)電(dian)(dian)(dian)鍍(du)反應(ying)中產(chan)(chan)(chan)生(sheng)(sheng)(sheng)的(de)熱量使(shi)電(dian)(dian)(dian)鍍(du)液(ye)(ye)的(de)溫(wen)(wen)度升(sheng)高(gao)。當(dang)電(dian)(dian)(dian)鍍(du)液(ye)(ye)溫(wen)(wen)度高(gao)于(yu)工業(ye)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)要求時，對工業(ye)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)電(dian)(dian)(dian)鍍(du)產(chan)(chan)(chan)品的(de)牢固度、均勻度、平(ping)整(zheng)度和(he)表面光潔度有很(hen)大影響。如果冷(leng)(leng)水機提供的(de)冷(leng)(leng)凍電(dian)(dian)(dian)子元(yuan)(yuan)件(jian)的(de)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)過程需要將(jiang)基(ji)本元(yuan)(yuan)件(jian)保(bao)持或(huo)冷(leng)(leng)卻(que)(que)在(zai)特(te)定(ding)的(de)溫(wen)(wen)度，則可以在(zai)設計狀(zhuang)態下控制(zhi)電(dian)(dian)(dian)子元(yuan)(yuan)件(jian)的(de)性(xing)(xing)能參數。采用水冷(leng)(leng)卻(que)(que)和(he)保(bao)持電(dian)(dian)(dian)鍍(du)液(ye)(ye)的(de)恒溫(wen)(wen)，大大提高(gao)了(le)電(dian)(dian)(dian)鍍(du)的(de)工業(ye)化(hua)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)和(he)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)效率，因為電(dian)(dian)(dian)鍍(du)行業(ye)具有很(hen)強的(de)腐(fu)蝕性(xing)(xing)。冷(leng)(leng)卻(que)(que)方式(shi)可分為直接冷(leng)(leng)卻(que)(que)和(he)間接冷(leng)(leng)卻(que)(que)：

i直(zhi)(zhi)接(jie)冷(leng)(leng)卻：即鍍液通(tong)過(guo)過(guo)濾(lv)器(qi)(qi)或濾(lv)網直(zhi)(zhi)接(jie)進(jin)入制冷(leng)(leng)機(ji)(ji)的(de)蒸(zheng)發(fa)器(qi)(qi)進(jin)行冷(leng)(leng)卻，然后返(fan)回(hui)氧化槽。這種冷(leng)(leng)卻方式(shi)的(de)優缺點：冷(leng)(leng)卻時間短，效果好；缺點是(shi)蒸(zheng)發(fa)器(qi)(qi)需要防腐處理（一般采(cai)用鈦合金）。蒸(zheng)發(fa)器(qi)(qi)容易結垢，需要定期清洗，否則會影響冷(leng)(leng)卻效果和機(ji)(ji)器(qi)(qi)運行。

間接冷(leng)卻(que)(que)：氧化槽內鋪(pu)設鈦(tai)管，冷(leng)凍水通過鈦(tai)管帶走輸送液的熱量，達到冷(leng)卻(que)(que)的目的；如果(guo)不方便(bian)鋪(pu)設鈦(tai)管，可加熱交換器(qi)（鈦(tai)合金(jin)材(cai)質），走冷(leng)卻(que)(que)水和鍍液

綜上(shang)所述，冷(leng)水(shui)機直接冷(leng)凍和(he)間接冷(leng)凍有很(hen)多相似之處，但(dan)直接冷(leng)凍冷(leng)水(shui)機不如間接冷(leng)凍冷(leng)水(shui)機安全，而且(qie)前者容易腐蝕，壽命短。
