在電鍍(du)生(sheng)(sheng)產(chan)(chan)(chan)中(zhong)，電鍍(du)液在電鍍(du)反應(ying)中(zhong)產(chan)(chan)(chan)生(sheng)(sheng)的熱(re)量使電鍍(du)液的溫度(du)(du)升(sheng)高。當(dang)電鍍(du)液溫度(du)(du)高于工(gong)(gong)(gong)業(ye)生(sheng)(sheng)產(chan)(chan)(chan)要求時，對工(gong)(gong)(gong)業(ye)生(sheng)(sheng)產(chan)(chan)(chan)的電鍍(du)產(chan)(chan)(chan)品的牢固度(du)(du)、均勻(yun)度(du)(du)、平整(zheng)度(du)(du)和表面(mian)光潔度(du)(du)有(you)很大(da)影響(xiang)。如果冷(leng)水機提(ti)供的冷(leng)凍電子元件的生(sheng)(sheng)產(chan)(chan)(chan)過程需要將基本元件保(bao)持(chi)或冷(leng)卻(que)在特定的溫度(du)(du)，則可以(yi)在設計狀(zhuang)態(tai)下控制(zhi)電子元件的性能參數。采(cai)用水冷(leng)卻(que)和保(bao)持(chi)電鍍(du)液的恒溫，大(da)大(da)提(ti)高了電鍍(du)的工(gong)(gong)(gong)業(ye)化生(sheng)(sheng)產(chan)(chan)(chan)和生(sheng)(sheng)產(chan)(chan)(chan)效率，因為電鍍(du)行(xing)業(ye)具有(you)很強的腐(fu)蝕(shi)性。冷(leng)卻(que)方(fang)式可分為直接冷(leng)卻(que)和間(jian)接冷(leng)卻(que)：

i直(zhi)(zhi)接冷(leng)卻：即(ji)鍍液通過過濾(lv)器或濾(lv)網直(zhi)(zhi)接進入制冷(leng)機(ji)的蒸(zheng)發器進行(xing)冷(leng)卻，然(ran)后(hou)返回氧(yang)化槽。這種冷(leng)卻方式(shi)的優缺點(dian)：冷(leng)卻時間(jian)短，效果好；缺點(dian)是蒸(zheng)發器需要防(fang)腐(fu)處理（一般采(cai)用鈦合金）。蒸(zheng)發器容易結垢，需要定期清洗，否則會影響(xiang)冷(leng)卻效果和(he)機(ji)器運行(xing)。

間(jian)接冷(leng)卻(que)：氧化槽內鋪(pu)設(she)鈦(tai)管，冷(leng)凍(dong)水通過鈦(tai)管帶(dai)走輸(shu)送液(ye)的熱量，達到冷(leng)卻(que)的目的；如果(guo)不方便鋪(pu)設(she)鈦(tai)管，可(ke)加(jia)熱交換器（鈦(tai)合金材質），走冷(leng)卻(que)水和(he)鍍液(ye)

綜上所述(shu)，冷(leng)(leng)(leng)水(shui)(shui)機(ji)直(zhi)接(jie)(jie)冷(leng)(leng)(leng)凍和間接(jie)(jie)冷(leng)(leng)(leng)凍有很(hen)多(duo)相(xiang)似之(zhi)處，但直(zhi)接(jie)(jie)冷(leng)(leng)(leng)凍冷(leng)(leng)(leng)水(shui)(shui)機(ji)不如間接(jie)(jie)冷(leng)(leng)(leng)凍冷(leng)(leng)(leng)水(shui)(shui)機(ji)安全，而且前者容易腐蝕，壽命(ming)短(duan)。
