Abstract

The invention provides a finned tube which comprises a tube body and fins. A plurality of fins are uniformly and symmetrically distributed on the outer periphery of the tube body. Each fin extends to the lower end of the tube body from the upper end of the tube body. The fins are divided into main fins and auxiliary fins. The outer ends of the main fins are in a rhombus shape. The main fins are connected with a connecting sheet connected with each finned tube. The outer ends of the auxiliary fins are round ends. According to the finned tube provided by the invention, connectors matched with the connecting sheet are arranged at the outer ends of the main fins and the outer ends of the auxiliary fins which are not connected with other parts are set into round shapes, so that objects are not easily scratched by the finned tube in the installing process and the strengths of the fins are reinforced.

Description

technical field [0001] The invention relates to a finned tube, which belongs to the field of heat exchange devices. Background technique [0002] As a heat exchange device, finned tubes are widely used. However, in general finned tubes, the edges of the fins are straight, which is easy to scratch objects during assembly. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the existing defects and provide a finned tube, which makes the assembly of the fins more convenient and can increase the strength of the fins at the same time. [0004] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0005] Finned tube, including tube body and fins, multiple fins are evenly and symmetrically distributed on the outer circumference of the tube body, each fin extends from the upper end of the tube body to the lower end, the fins are divided into main fin...
