    • 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.
    • 本发明涉及增强的传热表面和用于制造增强的传热表面的方法和工具。 某些实施例包括沸腾表面,其包括多个主要凹槽,突起和辅助凹槽以形成沸腾腔。 沸腾表面可以通过使用用于切割管的内表面的工具来形成。 该工具具有刀具轴线和至少一个具有切削刃和提升边缘的末端。 还公开了制造沸腾表面的方法,包括切割管的内表面以形成主槽,然后切割和提升内表面以形成突起和次级槽。
