Description
Technical field
A kind of finned tube is the utility model is related to, more particularly to a kind of lozenge fin tube and thus H types wing derived from structure
Piece pipe, suitable for various types of heat exchange of the industries such as electric power, chemical industry, metallurgy, steel, building and firing equipment.
Background technology
It is energy-saving to have become an important topic with China's expanding economy, have influence on the sustainable development in China
Exhibition process.Heat exchanger is visual plant commonly used in numerous industries such as the energy, chemical industry, metallurgy, building, and these industries
In main energy consumption source.The heat exchange efficiency of heat exchanger is improved, it is real and urgent for promoting the important industry development in China to have
Meaning.
The effect of heat exchanger is that the heat in a kind of medium is quickly delivered in another medium.When the biography of two media
When hot coefficient differs, flowing velocity, the enhancing heat transfer small medium and heat exchanger of the small medium of heat transfer coefficient are improved
Heat-transfer surface in contact area, Reasonable Arrangement heat exchanger, all it is to reduce heat transfer resistance, that improves heat exchanger heat exchange efficiency has efficacious prescriptions
Method.Fin tube type can make heat exchange area increase more than 5 times, be widely used by increasing fin on plain end pipe surface
In boiler, refrigeration and various industrial heat exchange devices.
With the continuous understanding to thermal conduction study, people develop spiral fins pipe and H type finned tubes.Spiral fins pipe
Fin be circle, be wrapped on base tube, fin and fluid flow to form certain angle.The wing coefficient of spiral fins pipe
Height, heat transfer efficiency is high, but the problem of easy dust stratification be present.H type finned tubes are the rectangle steel disc that circular arc is carried among two panels
Symmetrically it is welded on base tube, is gained the name because front shape is similar to alphabetical " H ".Space between H type finned tube two panels steel discs can
To play a part of water conservancy diversion, there is stronger self-cleaning ability.
Which kind of either finned tube, all it is arranged in the form of pipe is arranged in heat exchanger.The arrangement arranged according to pipe, is divided into
In-line is restrained and two kinds of bank of staggered pipes.Because the disturbance that fluid is subject to is less, the coefficient of heat transfer integrally restrained is relatively low for in-line tube bank.
When the arrangement of bank of staggered pipes, the gap between the adjacent two row fin of spiral fin coil is larger, can not make full use of space
Further improve heat exchange area；For H types finned tube because of square fin structure, the resistance of convection body is larger, and can not be managed by adjusting
Spacing is arranged further to improve the utilization rate of heat transfer space.
Patent CN104501639A take into account influence of the H types fin for incoming resistance, and fin shape is designed as into ladder
Shape or irregular quadrilateral, but this fin configuration will be formed necessarily in bank of staggered pipes arrangement between adjacent two rows fin
The space of shape, cause the waste of exchange heat space.
The content of the invention
In order to overcome prior art problem mentioned above, the heat exchange efficiency of finned tube exchanger, the utility model are improved
Purpose be to provide a kind of lozenge fin tube binding structure, improve the utilization rate of heat transfer space, solve H types finned tube presence
The larger problem of resistance, improve the heat exchange efficiency of heat exchanger, reduce the material consumption of heat exchanger.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of lozenge fin tube binding structure, including base tube 1 and fin 2, the quantity of the base tube 1 are at least one, described
Fin 2 is to be some along the axial direction of base tube 1 thin slice arranged in parallel being connected to constant spacing on base tube；Every fin is provided with
The semi-circular recesses being coincide with the outer wall shape of base tube 1, are stitched together with base tube 1；The structure that base tube 1 and fin 2 form is with pipe group
Form, be staggered in arrangement in heat exchanger or the spatial dimension that need to be exchanged heat.
The outer of fin 2 is rhombus, formed by the angle α on two sides of rhombus windward side and adjacent two base tubes circle center line connecting
Angle β is equal, and the α number of degrees according to be staggered in arrangement it is interbank change away from change, excursion 0<α<180°.
The base tube 1 is shaped as circular or ellipse.
The fin 2 uses punching press one-shot forming, is realized and is welded to connect with base tube 1 using semi-circular recesses, welding manner
For flash of light built-up welding or soldering.
The spacing b of fin 2 on the two neighboring base tube 1 on same plane is adjusted according to the spacing a of base tube 1, is adjusted
Whole scope is 0<b<a.
Any two relative angles or whole four angles, which become, in the rhombus outer of the fin 2 turns to arc-shaped；
The every fin 2 is symmetrical two panels isosceles triangle fin, forms the structure type of similar H type finned tubes,
The base angle γ of the isosceles triangle of fin 2 is the half of angle β formed by adjacent two base tubes circle center line connecting, i.e. γ=β/2.
Compared to the prior art, the utility model has following advantage to lozenge fin tube binding structure：
The utility model proposes a kind of lozenge fin tube binding structure, due to the angle α and phase on two sides of rhombus windward side
Angle β formed by adjacent two base tube circle center line connectings is equal, can effectively utilize the heat transfer space between base tube, improves heat exchange effect
Rate.In base tube spacing under the same conditions, the fin area of lozenge fin tube improves 10% than spiral fin coil, makes full use of spiral shell
The heat transfer space of adjacent two combs line midpoint when rotation finned tube is staggered in arrangement., can when the spacing b of fin 2 is especially small
To be covered with fin in whole space.
The utility model proposes a kind of lozenge fin tube binding structure, because fin is rhombus, air-flow is flowing through heat exchanger tube
Being flowed during row along fin side, flow trace is fold-line-shaped, can effectively guide flow of fluid, is advantageous to fluid Uniform Flow,
Heat transfer effect is improved, reduces resistance, reduces abrasion.Either spiral fin coil or H type finned tubes, fin institute is in the plane all
The fluid straight through flow path between fin be present, cause fluid short, influence flow field uniformity and heat transfer effect.Phase of the present utility model
It is fold-line-shaped between adjacent fin, in the absence of straight through flow path, guide functions can be effectively played, make flowing more uniform, heat transfer effect is more
It is good.Compared to H type finned tubes, the windward side of the utility model fin forms certain angle, and the resistance of convection body is smaller, can effectively delay
Solve abrasion of the fluid to the array of pipes of windward side first.
The utility model proposes a kind of lozenge fin tube binding structure, due to the angle α and phase on two sides of rhombus windward side
Angle β formed by adjacent two base tube circle center line connectings is equal, the angle that fin shape can be formed according to the adjacent base tube center of circle is staggered in arrangement
Change and change, broken away from influence of the fin shape size to base tube spacing, the pipe of different sizes, spacing can be flexibly applied to
In formula heat exchanger.The utility model fin windward side both sides angle α can change and adjust according to base tube spacing, and angle diminishes
When, base tube spacing also reduces, and more base tubes can be arranged when flue cross section is constant, advantageously reduces base tube row, reduces material and uses
Amount.
