在(zai)電(dian)(dian)(dian)鍍(du)(du)(du)(du)生(sheng)產(chan)(chan)(chan)(chan)(chan)中，電(dian)(dian)(dian)鍍(du)(du)(du)(du)液(ye)在(zai)電(dian)(dian)(dian)鍍(du)(du)(du)(du)反應(ying)中產(chan)(chan)(chan)(chan)(chan)生(sheng)的(de)(de)(de)熱量使電(dian)(dian)(dian)鍍(du)(du)(du)(du)液(ye)的(de)(de)(de)溫度(du)升高。當電(dian)(dian)(dian)鍍(du)(du)(du)(du)液(ye)溫度(du)高于工(gong)業生(sheng)產(chan)(chan)(chan)(chan)(chan)要求(qiu)時，對(dui)工(gong)業生(sheng)產(chan)(chan)(chan)(chan)(chan)的(de)(de)(de)電(dian)(dian)(dian)鍍(du)(du)(du)(du)產(chan)(chan)(chan)(chan)(chan)品的(de)(de)(de)牢固度(du)、均勻度(du)、平(ping)整度(du)和表面光潔度(du)有很大影響。如果冷水機(ji)提供(gong)的(de)(de)(de)冷凍電(dian)(dian)(dian)子(zi)元件(jian)(jian)的(de)(de)(de)生(sheng)產(chan)(chan)(chan)(chan)(chan)過程需(xu)要將基本元件(jian)(jian)保持或冷卻在(zai)特定的(de)(de)(de)溫度(du)，則可以(yi)在(zai)設計狀(zhuang)態(tai)下控制電(dian)(dian)(dian)子(zi)元件(jian)(jian)的(de)(de)(de)性(xing)能參(can)數。采用水冷卻和保持電(dian)(dian)(dian)鍍(du)(du)(du)(du)液(ye)的(de)(de)(de)恒(heng)溫，大大提高了(le)電(dian)(dian)(dian)鍍(du)(du)(du)(du)的(de)(de)(de)工(gong)業化生(sheng)產(chan)(chan)(chan)(chan)(chan)和生(sheng)產(chan)(chan)(chan)(chan)(chan)效率(lv)，因為(wei)電(dian)(dian)(dian)鍍(du)(du)(du)(du)行業具有很強的(de)(de)(de)腐蝕性(xing)。冷卻方式可分為(wei)直接冷卻和間(jian)接冷卻：

i直(zhi)接冷(leng)(leng)卻(que)：即(ji)鍍(du)液通過(guo)(guo)過(guo)(guo)濾(lv)器(qi)或濾(lv)網直(zhi)接進入制冷(leng)(leng)機的蒸(zheng)發器(qi)進行冷(leng)(leng)卻(que)，然(ran)后返(fan)回氧化槽。這(zhe)種(zhong)冷(leng)(leng)卻(que)方式的優(you)缺點(dian)：冷(leng)(leng)卻(que)時間短，效(xiao)果好；缺點(dian)是蒸(zheng)發器(qi)需(xu)要(yao)防腐處理（一般(ban)采(cai)用鈦合金）。蒸(zheng)發器(qi)容易結垢(gou)，需(xu)要(yao)定(ding)期清洗，否(fou)則會(hui)影響冷(leng)(leng)卻(que)效(xiao)果和機器(qi)運行。

間(jian)接冷卻：氧化槽內鋪(pu)設(she)鈦(tai)管，冷凍水(shui)通過鈦(tai)管帶走輸送液的(de)(de)(de)熱量，達到冷卻的(de)(de)(de)目的(de)(de)(de)；如(ru)果(guo)不方便鋪(pu)設(she)鈦(tai)管，可加熱交換器（鈦(tai)合金材質），走冷卻水(shui)和鍍液

綜上所述，冷(leng)水(shui)機直接(jie)冷(leng)凍和(he)間(jian)接(jie)冷(leng)凍有很多相(xiang)似(si)之處，但直接(jie)冷(leng)凍冷(leng)水(shui)機不如(ru)間(jian)接(jie)冷(leng)凍冷(leng)水(shui)機安全，而(er)且(qie)前者容易腐蝕，壽命(ming)短。
