摘要： An evaporation heat transfer tube has 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 has 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 intersect respectively with the side wall and the bottom plane.

摘要： The present invention relates to an evaporation heat transfer tube with a hollow cavity, comprising a tube main body and at least one hollow frustum structure. Outer fins are arranged at intervals on the outer surface of the tube main body and inter-fin grooves are formed between two adjacent outer fins. The hollow frustum structure is arranged at the bottom of the inter-fin grooves and surrounded by side walls. The top of the hollow frustum structure is provided with an opening. The side walls extend inwards and upwards from the bottom of the inter-fin grooves and thus the area of the opening is less than the area of the bottom of the hollow frustum structure. The inner surface and the outer surface of the side walls are intersected at the opening to form a flange. Preferably, the flange is a sharp corner and the radius of the curvature is 0 to 0.01 mm. The side walls are formed by at least two surfaces which are connected to each other. The hollow frustum structure is hollow pyramid frustum shaped, hollow volcano shaped or hollow cone frustum shaped. The height Hr and the height H of the inter-fin grooves meet the following relations: 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 of the tube and the liquid outside the tube, reinforcing the heat transfer in boiling and it is suitable for large-scale popularization and application.
