代替铜制水箱的铝制水箱已能大批生产。英国的 Covrad及A.E.公司用了七年时间从事研究,现已解决了轻金属水箱的工艺问题。用粘结代替焊接。铝制水箱不但能导热,而且成本低。散热片用Z形代替V形。连接处的接触面增大了很多,这是为了要克服粘结连接导热性能较低的问题。图示Covrad/A.E.的铝制水箱的结构。采用的人造树脂粘合剂可在-30+120℃的范围内 Aluminum tanks instead of copper tanks have been mass-produced. After seven years of research by the British companies Covrad and A.E., the process of light metal water tanks has been solved. Use bonding instead of welding. Aluminum water tanks not only heat, and low cost. Heat sink instead of V-shaped Z. The contact area at the connection has increased a lot in order to overcome the problem of a lower thermal conductivity of the bond connection. The structure of the aluminum radiator of Covrad / A.E. The artificial resin binder used may be in the range of -30 + 120 ° C
