Phase change heat dissipater of aluminium container

Due to the cupperpsilas increasing cost there is a trend to use more and more the aluminium instead of cupper. When using aluminium in phase change dissipaters there are two aspects that must be consider: one is the welding difficulty and other is the surface cleaning for a better wetting. It is very well known how much the solid surface quality affects on the liquidpsilas wetting capacity. At this point little is done on the aluminium cleaning process in order to improve the liquid wetting without damaging the material itself, thatpsilas to say, corrosion appearance.
