BOILING HEAT TRANSFER SURFACE, METHOD OF PREPARING SAME AND METHOD OF BOILING

摘要

Abstract:Improved nucleate boiling cavities are providedin a heat exchange surface by mechanically forming indentationson the heat transfer surface and then electrodepositing ametal on the pitted surface at a high current density followedby strengthening at lower current densities. Also describedis a method of transferring heat from a warm fluid to aboiling liquid utilizing the improved nucleate boilingstructure.
