    Abstract: A finned tube includes channels defined between adjacent fins on the tube body outer surface. Wings extend from side walls of the adjacent fins between the fin top and the fin base such that the wings form a barrier which splits the channel into an upper channel and a lower channel. A plurality of holes penetrate the barrier where the wings meet, so liquids and gases can pass into and out of the enclosed area defined by the lower channel. The wings can include alternating upper wings and lower wings, and there can be depressions formed in the fin top.

    Abstract: 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.

    Abstract: A heat exchange tube, a heat exchanger using such a tube and a method of making such a tube. Additive manufacturing is used to form at least a portion of the tube. Augmented heat exchange features, such as external and internal lattice structure may be built up along with the remainder of the tube to form an enhanced heat exchange region with intermittent, repeating shapes. Such shapes maximize heat-dissipating surface area of the tube while reducing or eliminating large external dimensions associated with traditional tube manufacture.
