High-performance and high-efficiency rolled fin tube and forming disk therefor |
摘要 |
Disclosed herein is a forming disk for fabricating a fin tube. The forming disk comprises a substantially circular plate having a shaft connection hole formed adjacent a center thereof for receiving a shaft of a form rolling machine. A plurality of projections having a first length are formed along a circumference of said plate at substantially regular angular intervals in such a way as to protrude in a radial direction, and a round curvature is formed in the formed fin at certain axial pitch periodically in a radial direction. Also disclosed is a high-performance and high-efficiency fin tube having formed fins. Each formed fin comprises a generally circular plate having a crest and a valley formed in both side faces at certain angular intervals along the circumference thereof so as to form a continuous curvature.
