ABSTRACT:
The invention relates to improving the heat transfer properties in boiling liquids of tubes and other surfaces by applying a very porous reticulated organic foam layer in contact with the tube surface, and then plating a thin metal coating on the foam substrate. Preferably, the tube is copper and the plating consists of a first electrolessly applied layer of copper and a second electroplated layer. The foam is preferably in the form of a thin tape which is spirally wound about the tube. Pyrolization of the foam after plating improves the heat transfer performance of the tube.
