Abstract

The utility model relates to a finned pipe with a jalousie arranged on a fin, in particular to an improvement to the structure of the finned pipe, in particular to a finned belt on the finned pipe. At present, for the finned pipe used home and overseas, the finned pipe is normally made in a way that a steel pipe adopts a high-frequency welded spiral fin or a bushed aluminium pipe rolling piece so the fins of the finned pipes are all plane structures with low flowing resistance for a heat exchanging medium, leading to low radiating and heat exchanging efficiency of the radiators and the heat exchangers. The utility model consists of a basic pipe (1) and the fin (2). The jalousie (3) is arranged on the fin (2), and the fin (2) with the jalousie (3) is fixed on the outer surface of the basic pipe (1). The utility model adopts the jalousie (grid) on the fin, and then three heat transferring ways, transmitting, radiating and convection, can be fully utilized. And especially the flow resistance of the natural liquid of the heat exchanging medium is increased, and the high efficiency and quick heat exchanging can be realized and the radiating and heat exchanging efficiency is enhanced. The utility model is suitable for various radiators and heat exchangers with simple structure.

Description

Have the finned tube of shutter on the fin

Technical field: the utility model relates to the improvement of fin tube structure, is specifically related to the fin band on the finned tube.

Background technology: at present, the finned tube that uses generally is to adopt the high-frequency welding helical fin or adopt the cover aluminum pipe to roll sheet to make on the steel pipe, because of its fin all is a planar structure both at home and abroad, the heat transferring medium flow resistance is little, causes the heat radiation heat exchange efficiency of radiator or heat exchanger not high.

The utility model content: the purpose of this utility model is the finned tube that has shutter on a kind of fin of development, and it has simple in structure, can increase the flow resistance of heat transferring medium, improves the characteristics of heat radiation heat exchange efficiency.The utility model is made up of parent tube 1, fin 2; Have shutter 3 on the fin 2, the fin 2 that has shutter 3 is fixed on the outer surface of parent tube 1.The utility model is owing to have shutter (grid leaf) on the fin, three kinds of transfer modes of hot conduction, radiation and convection current have been made full use of, especially the natural fluid flow resistance of heat transferring medium increases, and has realized efficient heat exchange fast, has improved heat radiation and heat exchange efficiency.The utility model is simple in structure, is applicable to various types of radiators and heat exchanger.

Description of drawings: Fig. 1 is that fin 2 hoops that have a shutter 3 are fixed on the structural representation on the parent tube 1, Fig. 2 is the A-A cutaway view of Fig. 1, Fig. 3 is that the fin 2 that has a shutter 3 is axially fixed in the structural representation on the parent tube 1, Fig. 4 be the B of Fig. 3 to view, Fig. 5 is the C-C cutaway view of Fig. 4.

The specific embodiment one: (seeing Fig. 1, Fig. 2, Fig. 5) present embodiment is made up of parent tube 1, fin 2; The equidistant shutter 3 that has on the fin 2, fin 2 hoops shape in the shape of a spiral are fixed on the outer surface of parent tube 1.

The specific embodiment two: the difference of the (see figure 4) present embodiment and the specific embodiment one is that fin 2 is axially fixed on the outer surface of parent tube 1.Other composition is identical with the specific embodiment one with annexation.

The specific embodiment three: the difference of the (see figure 3) present embodiment and the specific embodiment one is that four fin 2 cross sections are " X " oblique crank Z on the outer surface that is fixed on parent tube 1.Other composition is identical with the specific embodiment one with annexation.
