铜管又称紫铜管。有色金属管的一种,是压制的和拉制的无缝管。铜管具备了良好导电性,导热性的特性,电子产品的导电配件以及散热配件的主要材料,并且成为现代承包商在所有住宅商品房的自来水管道、供热、制冷管道安装的首选。铜管抗腐蚀性能强,不易氧化,且与一些液态物质不易起化学反应,容易炜弯造型。

The flow and heat transfer characteristics of tetrabutylammonium bromide(TBAB) clathrate hydrate slurry with 5.0%~20.0%volume fraction in 6 mm and 14 mm straight copper tubes were investigated.
本文实验研究了体积分数为5.0%~20.0%的四丁基溴化铵(TBAB)水合物浆体在内径为6 mm和14 mm的圆直铜管中的流动和换热特性。
