Description
Technical field
When improving pressure with compressor for industrial air, nitrogen the present invention relates to one kind, between compressor stage
And the heat exchanger core after compressor in heat exchanger.
Background technology
It is well known that compressor, in compressed gas, the temperature of gas can increase, heat exchanger is just used for cooling down compressed
Gas reduces gas temperature so that the gas temperature into compressor next stage is controlled, to reduce the pressure of compressor
Contracting work(, heat exchanger are main mating portion's machines of compressor, and the heat exchange property of heat exchanger will directly affect the compression efficiency of compression, change
Hot device in use, due to gas side and water side deposition so that heat exchange efficiency reduce, can also occur fin damage or air water string
Leakage, when serious, compressor is unable to operate normally.
Heat exchanger in use, the especially mating heat exchanger of Air turbocompressor, in gas containing dust,
The impurity such as carbon monoxide, carbon dioxide, these impurity are flowing through the heat exchanger core period of the day from 11 p.m. to 1 a.m with high temperature air, are easy to be attached to heat exchange
Fin surface, with the increase of usage time, fouling can be increasingly severe, can form local stoppages, with the expansion of blocking, leads to
The effective area of stream part can be smaller and smaller, and the gas flow rate of effective flow area part can become larger, and heat exchange fin can be caused to damage
It is bad.Usual air compressor heat exchange device fuse uses iron white copper pipe, aluminum fin-stock, after using a cycle, needs to do an inspection, change
Hot device needs core pulling to clean, if it find that fin well damage, must replace heat exchanger core, it is generally the case that windward side
One row's heat exchange fin damages first, improves the resistance to corrosion of row's fin, so that it may to extend the service life of heat exchanger core,
Row's fin material is changed to copper fin by aluminum fin-stock, effectively improves the service life of entire heat exchanger.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of simple in structure, safe and reliable, conjunction
Reason is efficient, and service life is long, can guarantee a kind of heat exchanger core minor structure of compressor normal operation in oxygenerator.
The purpose of the present invention is come what is completed, a kind of heat exchanger core minor structure, it includes heat exchange by following technical solution
Device tube sheet, heat exchanger tube and heat exchange fin, the heat exchange fin arrange respectively according to before and after multiple lines and multiple rows, and constitute multiple fin lists
Member；Wherein it is located at the windward side first row fin that air-flow introduces to be made of unlike material with each row's fin thereafter, to structure
At at least tool, there are two types of the heat exchanger cores of heat exchange fin.
As preferred：The windward side first row fin is copper fin, and all row's fins thereafter are aluminum fin-stock,
And copper fin and aluminum fin-stock shape, size are just the same, constituting front and back tool, there are two types of the heat exchanger cores of heat exchange fin.
The present invention have it is simple in structure, safe and reliable, rationally efficiently, service life is long, can guarantee in oxygenerator and compresses
The features such as machine normal operation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be described in detail：Shown in Fig. 1, a kind of heat exchanger core of the present invention
Structure, it includes heat exchanger tube sheet 1, heat exchanger tube 2 and heat exchange fin 3, and the heat exchange fin 3 is arranged respectively according to before and after multiple lines and multiple rows
Row, and constitute multiple fin units；Wherein it is located at the windward side first row fin 4 that air-flow introduces to adopt with each row's fin 5 thereafter
It is made of unlike material, to constitute at least tool, there are two types of the heat exchanger cores of heat exchange fin.
As preferred embodiment, windward side first row fin 4 of the present invention is copper fin, and all rows thereafter
Fin 5 is aluminum fin-stock, and copper fin and aluminum fin-stock shape, size are just the same, and constituting front and back tool, there are two types of heat exchange fins
Heat exchanger core.
As further embodiment, heat exchanger structure of the present invention design be exactly by windward side first row fin more
Change copper fin into, remaining each row still uses aluminum fin-stock, and fin thickness, shape, spacing of fin can be just the same, it is possibility to have institute
Difference, since the resistance to corrosion of copper fin is stronger than aluminum fin-stock, and fin damage is also first occurred from first row head, using this
The service life of structure, heat exchanger will extend, if all using copper fin, cost will increase, and of the invention is this
Structure cost performance highest has engineering value.
Embodiment：
（a）It first carries out heat exchanger to be calculated with aluminum fin-stock heat exchange, determines the heat exchange area of heat exchanger, also determine heat exchanger core
Windward side length 3635mm, width 636mm and fin depth 815mm, as shown in Figure 1, fin specification is 105 × 101mm, arrangement
It is arranged for 8 rows 8, amounts to 64 fin units.
（b）The aluminum fin-stock of first row is replaced with copper fin, remaining seven row is constant.
（c）Due to same specification copper fin heat exchange property will due to aluminum fin-stock, so, improved heat exchanger core knot
Structure heat exchange property increases than original structure, can guarantee heat exchange property.
