在電(dian)(dian)(dian)(dian)鍍(du)(du)生(sheng)(sheng)產(chan)(chan)(chan)中，電(dian)(dian)(dian)(dian)鍍(du)(du)液在電(dian)(dian)(dian)(dian)鍍(du)(du)反應(ying)中產(chan)(chan)(chan)生(sheng)(sheng)的(de)(de)(de)(de)熱量使電(dian)(dian)(dian)(dian)鍍(du)(du)液的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)升高(gao)。當電(dian)(dian)(dian)(dian)鍍(du)(du)液溫(wen)(wen)度(du)(du)高(gao)于工業(ye)生(sheng)(sheng)產(chan)(chan)(chan)要求時，對工業(ye)生(sheng)(sheng)產(chan)(chan)(chan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)鍍(du)(du)產(chan)(chan)(chan)品的(de)(de)(de)(de)牢固度(du)(du)、均(jun)勻度(du)(du)、平整度(du)(du)和(he)表(biao)面光潔度(du)(du)有很大影(ying)響。如(ru)果(guo)冷水(shui)機提供的(de)(de)(de)(de)冷凍電(dian)(dian)(dian)(dian)子(zi)元(yuan)件的(de)(de)(de)(de)生(sheng)(sheng)產(chan)(chan)(chan)過程需要將基本元(yuan)件保持(chi)或冷卻(que)在特(te)定(ding)的(de)(de)(de)(de)溫(wen)(wen)度(du)(du)，則可以在設計狀態下控制電(dian)(dian)(dian)(dian)子(zi)元(yuan)件的(de)(de)(de)(de)性(xing)能參數。采(cai)用水(shui)冷卻(que)和(he)保持(chi)電(dian)(dian)(dian)(dian)鍍(du)(du)液的(de)(de)(de)(de)恒溫(wen)(wen)，大大提高(gao)了電(dian)(dian)(dian)(dian)鍍(du)(du)的(de)(de)(de)(de)工業(ye)化(hua)生(sheng)(sheng)產(chan)(chan)(chan)和(he)生(sheng)(sheng)產(chan)(chan)(chan)效率，因為(wei)電(dian)(dian)(dian)(dian)鍍(du)(du)行業(ye)具(ju)有很強的(de)(de)(de)(de)腐蝕性(xing)。冷卻(que)方(fang)式可分(fen)為(wei)直接(jie)冷卻(que)和(he)間接(jie)冷卻(que)：

i直(zhi)接冷(leng)卻(que)(que)：即鍍液通(tong)過(guo)過(guo)濾器(qi)或濾網直(zhi)接進入制冷(leng)機的蒸發器(qi)進行冷(leng)卻(que)(que)，然后返回氧化(hua)槽。這種冷(leng)卻(que)(que)方(fang)式(shi)的優(you)缺點：冷(leng)卻(que)(que)時間短，效果好；缺點是(shi)蒸發器(qi)需(xu)要防腐處理（一般采用鈦合金）。蒸發器(qi)容易結垢，需(xu)要定期清洗，否(fou)則會影響冷(leng)卻(que)(que)效果和機器(qi)運行。

間(jian)接冷(leng)(leng)卻(que)(que)：氧化槽內鋪(pu)設鈦管，冷(leng)(leng)凍水通過鈦管帶走輸送(song)液(ye)的熱量，達到(dao)冷(leng)(leng)卻(que)(que)的目(mu)的；如果不方便鋪(pu)設鈦管，可加熱交(jiao)換器(qi)（鈦合金材質），走冷(leng)(leng)卻(que)(que)水和鍍液(ye)

綜上所(suo)述，冷(leng)(leng)(leng)(leng)(leng)水(shui)機直接(jie)冷(leng)(leng)(leng)(leng)(leng)凍(dong)和間接(jie)冷(leng)(leng)(leng)(leng)(leng)凍(dong)有很多(duo)相似之處，但直接(jie)冷(leng)(leng)(leng)(leng)(leng)凍(dong)冷(leng)(leng)(leng)(leng)(leng)水(shui)機不如間接(jie)冷(leng)(leng)(leng)(leng)(leng)凍(dong)冷(leng)(leng)(leng)(leng)(leng)水(shui)機安(an)全，而且前者容易(yi)腐(fu)蝕，壽命(ming)短。
