초록 ▼

The invention is concerned with a heat transfer tube for use in boiling type heat exchangers, having an excellent heat transfer performance. More specifically, the invention relates to a surface condition of the heat transfer tube for improving the heat transfer performance and a method of producing the tube easily, especially a method for processing the surface condition efficiently and advantageously from an industrial point of view. The essential feature of the invention resides in a provision of a surface condition for promoting the boiling which consists of annular or spiral cavities extending along the tube surface in the circumferential direction of the latter, as well as narrow gaps extending along the cavities so as to allow the cavities to communicate the outside space. If necessary, spiral or annular fins may be provided on the tube surface, so as to improve the boiling performance at the outside of the tube. Further, as a mechanism for promoting the boiling also in the axial direction of the tube, as well as in the circumferential direction, axially extending cavities and narrow gaps extending along the axially extending cavities for communication of the latter with the outside space may be formed on the tube surface, so as to remarkably improve the boiling performance at the outside of the tube.

대표청구항 ▼

A heat transfer tube for use in boiling type heat exchangers characterized by comprising annular or spiral cavities formed in the tube surface, said cavities becoming narrow from corresponding opposite sides forming narrow gaps at the end of said cavities, where said cavities communicate with the outside space through said narrow gaps, said cavities being separated by fins having thickened head portions, said head portions having broad upper surfaces, at least a portion of the periphery of said head portions forming the periphery of said narrow gaps.
