style="text-indent:25px">管殼式換熱器是一個量大而品種繁多的產(chǎn)品，迫切需要新的耐磨損、耐腐蝕、**度材料。我國在發(fā)展不銹鋼銅合金復(fù)合材料、鋁鎂合金及碳化硅等非金屬材料等方面都有不同程度的進(jìn)展，其中尤以鈦材發(fā)展較快。鈦對海水、氯堿、醋酸等有較好的抗腐蝕能力，如再強(qiáng)化傳熱，效果將更好，一些制造單位已較好的掌握了鈦材的加工制造技術(shù)。對材料的噴涂，我國已從國外引進(jìn)生產(chǎn)線。鋁鎂合金具有較高的抗腐蝕性和導(dǎo)熱性，價格比鈦材便宜，應(yīng)予注意。國內(nèi)在節(jié)能增效等方面改進(jìn)換熱器性能，提高傳熱效率，減少傳熱面積降低壓降，提高裝置熱強(qiáng)度等方面的研究取得了明顯成績。換熱器常用的檔板有圓缺形和圓盤形兩種。</p><div
