Description
Technical field
The utility model relates to technical field of heat exchangers, in particular to a kind of fin tube structure of heat exchanger.
Background technique
It is a kind of high-performance heat transfer components with spiral fin that finned tube, which is especially spiral finned tube,.Its heat-transfer area
Product is several times to tens times of light pipe, and energy augmentation of heat transfer reduces flow resistance, metal wastage reduced, to improve heat exchange
The economy and operational reliability of equipment.Currently, spiral fin coil is widely used in various heat exchangers.Spiral fin coil can
It is manufactured using a variety of methods, currently, the finned tube on the heat exchange equipments such as heat exchanger, pressure vessel is mainly the following system
Make method：High-frequency resistance welding (HFRW) spiral fin coil, soldering spiral fin coil and one-piece auger finned tube.The heat exchanger of the prior art
Fin tube structure is relatively simple, the disadvantage is that being easy to generate dust stratification in the junction of fin and pipe fitting.
Utility model content
In view of the deficienciess of the prior art, the main purpose of the utility model is to provide one kind can be avoided in tubing string
The fin tube structure of the heat exchanger of dust stratification is generated with fin junction.
To achieve the above object, the utility model provides following technical solution：A kind of fin tube structure of heat exchanger, packet
The multiple fins for including tubing string and being arranged on tubing string, the tubing string include inlet end and outlet side, the multiple fin
For height from inlet end towards outlet side gradually small setting on tubing string, the bottom of the multiple fin, which is provided with, leads grey hole.
Preferably, the spacing of the multiple fin is on tubing string from inlet end towards outlet side gradually small setting.
Preferably, arc convex portion is provided between adjacent two finned tube on the tubing string.
Preferably, wear-resistant coating is provided on the multiple fin.
The utility model has the following advantages compared with the prior art, a kind of finned tube knot of heat exchanger of the utility model
Structure, compared with the existing technology the advantages of be the dust stratification problem for being able to solve fin Yu tubing string junction, realize process be,
In the flow process of air-flow, the air-flow of inlet end can gradually high fin successively stops by height, and the air-flow being blocked can rush at
Tubing portion between adjacent fins enables the dust stratification on the tubing string between adjacent fins to be entrained by the flow of air, leads grey hole
Design can provide the channel being discharged downwards for dust stratification, so that dust stratification is difficult to adhere on tubing string, the structure of this programme is simple, energy
Enough solve the problems, such as tubing string and fin junction dust stratification.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the fin tube structure of heat exchanger of the utility model.
In figure：1, tubing string；2, fin；3, inlet end；4, outlet side；5, grey hole is led；6, arc convex portion.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of fin tube structure of heat exchanger, including tubing string 1 and the multiple fins being arranged on tubing string 1
2, the tubing string 1 includes inlet end 3 and outlet side 4, and the height of the multiple fin 2 is on tubing string 1 from inlet end 3 towards out
The gradually small setting of gas end 4, the bottom of the multiple fin 2, which is provided with, leads grey hole 5.
A kind of fin 2 pipe structure of the heat exchanger of the utility model, compared with the existing technology the advantages of be to be able to solve
The dust stratification problem of fin 2 and 1 junction of tubing string, the process realized is, in the flow process of air-flow, the air-flow of inlet end 3
Can by height, gradually high fin 2 successively stops, the air-flow being blocked can rush at 1 part of tubing string between adjacent fins 2, so that phase
The dust stratification on tubing string 1 between adjacent fin 2 can be entrained by the flow of air, and the design for leading grey hole 5 can provide downward discharge for dust stratification
Channel so that dust stratification is difficult to adhere on tubing string 1, the structure of this programme is simple, is able to solve tubing string 1 and 2 junction of fin
The problem of dust stratification.
Preferably, the spacing of the multiple fin 2 is on tubing string 1 from inlet end 3 towards the gradually small setting of outlet side 4.Because
Air-flow can become smaller gradually, and from inlet end 3 towards outlet side 4, gradually small setting enables to gas to the spacing of multiple fins 2 on tubing string 1
Stream generates vortex between fin 2 adequately to remove dust stratification.
Preferably, arc convex portion 6 is provided between adjacent two fins, 2 pipe on the tubing string 1.6 energy of arc convex portion
Enough so that air-flow generates eddy flow to tubing string 1, dust stratification is further avoided.
Preferably, wear-resistant coating is provided on the multiple fin 2.Wear-resistant coating can increase the wear-resisting property of fin 2,
Improve the service life of fin 2.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
