Novel H-shaped finned tube and H-shaped finned tube heat exchanger

Abstract

The invention provides a novel H-shaped finned tube and an H-shaped finned tube heat exchanger, and belongs to the technical field of heat exchangers. The novel H-shaped finned tube and the H-shaped finned tube heat exchanger comprise a heat exchange header, and a heat exchange mechanism is arranged in the heat exchange header; the heat exchange mechanism is composed of an H-shaped fin double-tube structure, an inlet connector structure and an outlet connector structure, the inlet connector structure and the outlet connector structure are connected to the head end and the tail end of the H-shaped fin double-tube structure, the whole device is reasonable in structural arrangement, ingenious in conception, flexible to use and high in heat exchange efficiency, and compared with fin tube structures in a common heat exchanger, the H-shaped fin double-tube structure in the device is arranged in sequence. The surface space of the base tube is divided into a plurality of small areas through the fins, the fins have the flow equalizing effect on smoke, compared with light tubes or spiral fins arranged in a staggered mode, the steel structure performance is good, deformation is not prone to occurring, the abrasion life is longer, meanwhile, the double-tube structure can improve the heat exchange flow and efficiency, heat energy waste is avoided, and high practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a novel H-shaped finned tube and an H-shaped finned tube heat exchanger. Background technique [0002] A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added on the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency, such a heat exchange tube. [0003] There are many types of finned tubes. According to the different installation positions of the fins, there are two types of finned tubes: inner finned tubes and outer finned tubes. Among them, the application of external finned tubes is more common. There are two types of tubes: longitudinal finned tubes and transverse finned tubes. Depending on the shape of the base tube, finned tubes include round finned tubes, e...

Problems solved by technology

[0005] The purpose of the present invention is to provide a novel H-shaped finned tube and H-shaped finned tube heat exchanger, which aims to solve the problem of the flow resistance of the flue gas side that still exists when the finned tube is installed in the heat exchanger in the prior art. It is still relatively large; the heat transfer coefficient on the flue gas side is relatively small; and the ability to resist fly ash wear is not strong enough, the service life is not long enough, the steel structure of the single-finned tube is not good, easy to deform, and the wear life is short.
