    摘要: A heat exchanger includes a plurality of longitudinally-extending first channels and a plurality of second channels fluidly isolated from the plurality of first channels. Each first channels includes a plurality of spiraling internal fins and a plurality of external fins. The internal fins extend from and are integrally formed with the internal walls of the first channel. The external fins connect extend from and are integrally formed with the external walls of the first channels, connecting channels together. The plurality of second channels is defined in part by external walls of the plurality of first channels and the plurality of external fins.

    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: A method for manufacturing a flat pipe 1 with concave-convex shapes on inner and outer surfaces includes making incisions with an expanded shape of the flat pipe 1 in a metal thin plate 2 such that intermediate portions 4 (middle portions) in the expanded shape of the flat pipe 1 widthwise of the expanded shape are left uncut from the thin plate 2, machining the concave-convex shapes in a range of the expanded shape of the flat pipe 1 and raising the expanded shape of the flat pipe 1 from the thin plate 2 as cut-and-raised pieces 8 with the uncut intermediate portions 4 in between, closing tips of the cut-and-raised pieces 8 together to form an overall shape of the flat pipe 2, and separating the uncut intermediate portions 4 from the thin plate 2 to obtain the flat pipe 1.

    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.
