ABSTRACT:
Improved nucleate boiling cavities are provided in a heat exchange surface by mechanically forming indentations on the heat transfer surface and then electrodepositing a metal on the pitted surface at a high current density followed by strengthening at lower current densities. Also described is a method of transferring heat from a warm fluid to a boiling liquid utilizing the improved nucleate boiling structure.
