Abstract (en)
[origin: WO2005043062A3] The invention relates to enhanced heat transfer surfaces and methods and tools for making enhanced heat transfer surface. Certain embodiments include a boiling surface that include a plurality of primary grooves, protrusions and secondary grooves to form boiling cavities. The boiling surface may be formed by using a tool for cutting the inner surface of a tube. The tool has a tool axis and at least one tip with a cutting edge and a lifting edge. Methods for making a boiling surface are also disclosed, including cutting through the inner surface of a tube to form primary grooves, then cutting and lifting the inner surface to form protrusions and secondary grooves.
