2, the oval steel pipe socket rectangle steel fin of galvanizing (Ji Yiai type) is by the invention of German Ji Yiai (GEA) company, and the applicating history in existing more than 60 year comprises that a plurality of countries in the world of China have introduced this technology.Fin is enclosed within one by one and forms finned tube on the elliptical tube by with the steel band drawing.Equally, finned tube must be carried out hot galvanizing surface and handle, on equipment heat exchange type selecting, also will choose bigger heat exchange area and increase bigger weight of equipment.
3, oval steel pipe is used by German Bark Dole (Balck-Durr) company at first around steel fin (Bark Dole type).Steel band is wrapped on the oval steel pipe both in conjunction with forming finned tube, for reaching anticorrosion and making the fin root and the purpose of the tight adhesion of parent tube, finned tube must be carried out the hot galvanizing surface processing; Compare with aluminium, the thermal conductivity of steel is mutually far short of what is expected, therefore will increase much choosing of heat exchange area, and outfit of equipment weight nearly doubles.
Because above-mentioned three kinds of finned tubes all can be thought the combination of a plurality of monomer fins and parent tube all to have heat exchange efficiency low, it is big to manage outer gas-flow resistance, and the defective that should not clean of fin.Have simultaneously that manufacturing procedure is numerous and diverse, production efficiency is low, lumber recovery is unstable, process equipment takes up room greatly, the defective of heat transfer efficiency difference, the environment protection treating problem also is the bottleneck on technology is used.
Summary of the invention
The purpose of this utility model is to provide a kind of mouth organ type finned tube, this kind finned tube has utilized soldering tech, not only overcome the shortcoming of current three kinds of finned tubes commonly used, kept up-to-date performance, also possesses better manufacturability, make Direct Air-Cooled and indirect air cooling process equipment reach integrated in production, realized the maximization of process equipment and utilization of area, also broken away from environmental pollution improvement's problem.
The technical scheme that its technical problem that solves the utility model adopts is: the described mouth organ type of present embodiment finned tube is made up of mouth organ type heat exchange parent tube and soldering fin thereon, wherein mouth organ type heat exchange parent tube outward appearance is flat tube, two major opposing sides are parallel surface, dual-side is semi arch, inside is provided with reinforcement, and heat exchange parent tube inner chamber is divided into a plurality of through holes that are parallel to each other; Wherein the fin outward appearance is waveform, and adjacent intermediate is parallel, and two ends are the semi arch transition.
Described is the enhanced heat exchange effect, and heat exchange parent tube inner surface of tube wall processes concavo-convex groove.
Described fin surface rolls out concavo-convex lines.
Heat exchange parent tube and fin all adopt high-strength aluminum alloy material.
The beneficial effect that the utility model has is: owing to adopt the single tube loose structure, be equivalent to a plurality of finned tube assemblies together, therefore simplified fin tube structure and processing technology greatly, reduced manufacturing cost; Owing to adopt all-aluminium construction, finned tube assembly weight with select 2, select 3 to compare and reduced closely 60%, air cooling system support steel structure and civil engineering structure obtain simplification, have reduced the overall system cost; By the concavo-convex groove enhanced heat exchange of heat exchange parent tube, optimized heat exchanger performance; Take full advantage of existing process equipment and place, produced tangible economic benefit; Save the finned tube surface treatment procedure, efficiently solved problem of environmental pollution.
