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.
摘要翻译： 本发明涉及具有中空腔的蒸发传热管，其包括管主体和至少一个中空的截头锥体结构。 外管翅片间隔设置在管主体的外表面上，并且在两个相邻的外翅片之间形成有间翅槽。 中空的截头锥体结构设置在肋间槽的底部并被侧壁包围。 空心平截头体结构的顶部设有开口。 侧壁从鳍状槽的底部向内和向上延伸，因此开口的面积小于中空平截头体结构的底部的面积。 侧壁的内表面和外表面在开口处相交以形成凸缘。 优选地，凸缘是锐角，曲率半径为0至0.01mm。 侧壁由至少两个彼此连接的表面形成。 中空的截头锥体结构是中空锥体截头锥形，中空的火山形或中空圆锥截头锥形。 翅片间槽的高度Hr和高度H满足以下关系：Hr / H大于或等于0.2。 本发明巧妙设计，结构简洁，显着提高了管外表面与管外液体之间的沸腾系数，加强了沸腾传热，适合大规模普及应用。

摘要： A double pipe type heat exchanger includes an inner pipe having a first flow path defined therein and an outer pipe arranged around the inner pipe to define a second flow path between the inner pipe and the outer pipe. The inner pipe includes a spiral groove formed on an outer circumferential surface of the inner pipe to extend along a longitudinal direction of the inner pipe. The outer pipe includes a reduced diameter portion protruding inwardly so that the inner surface of the outer pipe is intermittently contacted with the outer circumferential surface of the inner pipe.
