制冷機(ji)等(deng)換熱(re)器在(zai)制作時，管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)與列管(guan)(guan)(guan)(guan)(guan)的(de)(de)(de)(de)(de)焊接一般采用(yong)手工(gong)電弧焊，焊縫(feng)形狀存在(zai)不(bu)同程(cheng)度的(de)(de)(de)(de)(de)缺(que)陷(xian)，如凹陷(xian)、氣孔、夾渣(zha)等(deng)，焊縫(feng)應力(li)的(de)(de)(de)(de)(de)分(fen)布也(ye)不(bu)均勻。使用(yong)時管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)部分(fen)一般與工(gong)業冷卻水接觸，而工(gong)業冷卻水中(zhong)的(de)(de)(de)(de)(de)雜質(zhi)(zhi)(zhi)、鹽類、氣體、微生物都會(hui)(hui)構成對(dui)管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)和(he)(he)焊縫(feng)的(de)(de)(de)(de)(de)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)。這就(jiu)是(shi)(shi)我們常(chang)說(shuo)的(de)(de)(de)(de)(de)電化學(xue)(xue)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)。研究表明，工(gong)業水無論是(shi)(shi)淡水還(huan)(huan)是(shi)(shi)海(hai)水，都會(hui)(hui)有(you)各(ge)種(zhong)離(li)子和(he)(he)溶解的(de)(de)(de)(de)(de)氧氣，其中(zhong)氯離(li)子和(he)(he)氧的(de)(de)(de)(de)(de)濃度變化，對(dui)金屬的(de)(de)(de)(de)(de)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)形狀起(qi)重要(yao)作用(yong)。另(ling)外，金屬結(jie)構的(de)(de)(de)(de)(de)復雜程(cheng)度也(ye)會(hui)(hui)影響腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)形態。因此，管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)與列管(guan)(guan)(guan)(guan)(guan)焊縫(feng)的(de)(de)(de)(de)(de)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)以孔蝕(shi)(shi)(shi)(shi)(shi)(shi)和(he)(he)縫(feng)隙腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)為主(zhu)。從外觀看，管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)表面會(hui)(hui)有(you)許多腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)產物和(he)(he)積沉物，分(fen)布著(zhu)大小(xiao)不(bu)等(deng)的(de)(de)(de)(de)(de)凹坑。以海(hai)水為介質(zhi)(zhi)(zhi)時，還(huan)(huan)會(hui)(hui)產生電偶腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)。化學(xue)(xue)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)就(jiu)是(shi)(shi)介質(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)，換熱(re)器管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)接觸各(ge)種(zhong)各(ge)樣的(de)(de)(de)(de)(de)化學(xue)(xue)介質(zhi)(zhi)(zhi)，就(jiu)會(hui)(hui)受到(dao)化學(xue)(xue)介質(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)。另(ling)外，換熱(re)器管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)還(huan)(huan)會(hui)(hui)與換熱(re)管(guan)(guan)(guan)(guan)(guan)之(zhi)間產生一定的(de)(de)(de)(de)(de)雙金屬腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)。一些管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)還(huan)(huan)長期處于(yu)腐(fu)蝕(shi)(shi)(shi)(shi)(shi)(shi)介質(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)沖(chong)蝕(shi)(shi)(shi)(shi)(shi)(shi)中(zhong)。尤其是(shi)(shi)固定管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)換熱(re)器, 還(huan)(huan)有(you)溫差應力(li), 管(guan)(guan)(guan)(guan)(guan)板(ban)(ban)(ban)(ban)與換熱(re)管(guan)(guan)(guan)(guan)(guan)聯接處*易泄漏,導致換熱(re)器失(shi)效

低(di)溫(wen)水(shui)冷(leng)(leng)式常溫(wen)冷(leng)(leng)卻控溫(wen)設備是將(jiang)充足(zu)的水(shui)注入機器內部(bu)(bu)水(shui)箱，利用制冷(leng)(leng)系統將(jiang)水(shui)冷(leng)(leng)卻，冷(leng)(leng)凍(dong)后的水(shui)將(jiang)帶走設備內部(bu)(bu)的熱量。然后機器內部(bu)(bu)的循環(huan)泵將(jiang)低(di)溫(wen)冷(leng)(leng)凍(dong)水(shui)流(liu)到(dao)(dao)需要(yao)制冷(leng)(leng)的設備中(zhong)，再將(jiang)高溫(wen)熱水(shui)流(liu)到(dao)(dao)水(shui)箱中(zhong)，完(wan)成制冷(leng)(leng)。
