簡述銅鋁復合翅片管的基本原理

發布時間:2021-03-20  點擊次數:2867 次
       銅鋁復合翅片管是指銅管,鋁管經復合后的產品。復合一般是指根據所需翅片管特規格的鋁管套在銅管的外面,再在軋機上軋制而成的翅片管。具有結合緊密,熱阻小,傳熱性能好,強度高,流動損失小,防腐蝕性能較強,在長期冷熱工況下不易變形,工作壽命長等優點。
       銅鋁復合翅片管一般用在管內液體管外氣體的空氣熱交換狀況,管內的液體一般為水,水的混合溶液,乙二醇等冷卻介質。用銅管作為基管的情況下,切忌管內介質不能走蒸汽和導熱油的。壓力過大或者溫度過高會導致管子變形開裂易漏易彎。
       銅鋁復合翅片管在同種工況下使用時,導熱系數大,導熱效果好,占地面積小,外形美觀漂亮。
