Abstract
The utility model relates to a pipe of double H-shaped fins. Double-hole fins are symmetrically arranged on the radial direction of two parallel heat exchange pipes. The utility model has the advantages of compact structure, reasonable design, easy installation, good rigidity, no torsion, good radiating effect, low comprehensive cost, no dust accumulation, stable heat exchange properties and long service life. The space occupied by a heat exchanger made of the pipe is 40 to 60 percents of space occupied by a heat exchanger made of light pipes under the condition of the same heat exchange rate. The amount of gas saved by the pipe is 1.5 times of that saved by the existing light pipes.
Description
Technical field
The utility model relates to a kind of heat-transfer pipe, especially relates to a kind of double H-type gilled tube.
Background technology
At present, for making boiler convection heating surface compact conformation, reduce the consumption of metal material, fume side at convection heating surface adopts the extended surface heating surface, main vertical fin heating surface or the membrane type heating surface of adopting, but their the extended surface heating surface area quantity that heating surface increased is quite limited, for further reducing the space that heating surface occupied, bring into use the heating surface of spiral ribs chip in recent years, but the heating surface of spiral ribs chip only can be used for dust free air-flow, as combustion gas, in the oil burning boiler, coal-burning boiler at many dusts is then grey at the intrafascicular easy knot of heating surface tube, cause the obstruction of exhaust gases passes, because the heated face structure compactness of spiral ribs chip, in case the knot ash will be difficult to remove, influence the safe operation of equipment, and the heat-transfer pipe of spiral ribs chip is owing to be subjected to the restriction of fin with steel band ductility, and its fin height is restricted, and extended surface is low.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and good rigidly, good heat dissipation effect, the double H-type gilled tube of applied range easily are installed.
In order to achieve the above object, the technical solution adopted in the utility model is: at the diplopore fin that radially is welded with symmetry of two parallel heat exchanger tubes.
The utility model has the advantages that:
Compact conformation, reasonable in design is easily installed, under identical heat transfer rate, to take up space be the 40-60% of light pipe heat exchanger, good rigidly, non-warping, good heat dissipation effect, integrated cost is cheap, not dust stratification, heat exchange property is stable, and long service life is 1.5 times that present light pipe is economized coal gas.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A of Fig. 1 is to enlarged diagram.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is at the diplopore fin 2 that radially is welded with symmetry of two parallel heat exchanger tubes 1.
The utility model is because two parallel heat exchanger tubes are symmetrically welded with several diplopore fins, so compact conformation, saves space and material, integrated cost is cheap, simultaneously because the intensity of two heat exchanger tubes is big, therefore, the utility model double H-type gilled tube good rigidly, non-warping and distortion.Because two heat exchanger tubes are symmetrically welded with several diplopore fins, area of dissipation is big, the effectively generation heat exchange of maximum, so thermal efficiency height.The utility model heat exchanger tube is symmetrically welded with the several holes fin, makes fin form the air channel naturally, and dust is difficult for being detained on fin.The utility model is applicable to station boiler H type economizer, industry and marine boiler, waste heat boiler, oilfield gas injection stove, bioelectrogenesis boiler etc.
Claims (1)
1. a double H-type gilled tube comprises fin, it is characterized in that: at the diplopore fin (2) that radially is welded with symmetry of two parallel heat exchanger tubes (1).
