HEAT TRANSFER PROMOTING METHOD AND BOILING HEAT TRANSFER

摘要

PROBLEM TO BE SOLVED: To provide a method by which boiling heat can be effectively transferred even in the case of liquid easily wetting a surface.;SOLUTION: A surface roughness 2 with recessed and protruding parts 3 and 4 having the height of 10 nm to 1000 nm crowded is formed on a surface on which liquid boils and a surface treatment for effectively performing a heat transfer to liquid from the surface is carried out. In the surface treatment, a thin film may be formed on the surface by a sputtering or chemical vapor deposition method(CVD method) or a fine roughness may be formed on the surface by a wet etching method or a wet etching method after the thin film is formed.;COPYRIGHT: (C)2002,JPO
