Abstract

The invention relates to an evaporation heat transfer tube which comprises a tube main body and a step like structure; outer fins are arranged at intervals on the outer surface of the tube main body and an inter fin groove is formed between two adjacent outer fins; the step like structure respectively abuts against the bottom plane and one of the side walls of the inter fin groove. The step like structure comprises a first surface a second surface and at least one flange formed by the intersection of the two surfaces wherein the first and the second surface are intersected respectively with the side wall and the bottom plane. Preferably the first surface and the side wall are intersected to form a sharp corner; the second surface and the bottom plane are intersected to form a sharp corner the radius of curvature is 0 to 0.01 mm the angle formed by the first surface and the side wall is less than or equal to 90 degree or the angle formed by the second surface and the bottom plane is less than or equal to 90 degree. The height Hr of the step like structure and the height H of the inter fin groove meet the following relation: Hr/H is greater than or equal to 0.2. The present invention is ingeniously designed and concisely structured and it remarkably enhances the boiling coefficient between the outer surface and the liquid outside the tube and it reinforces the heat transfer in boiling and is suitable for large scale application.
