Abstract
The utility model provides a kind of efficient heat transfer anticorrosion heat exchanger tube; comprise lined steel pipe; it is characterized in that; closely wrap up hot-pressed aluminium fin protective layer outward at lined steel pipe, described hot-pressed aluminium fin protective layer comprises by the thin aluminium protective layer between the aluminium fin of hot-pressed formation and aluminium fin.Hot-pressed aluminium fin protective layer can alleviate heat exchanger tube corrosion greatly, expands the heating surface area of heat exchanger tube, the heat transfer of thermoexcell simultaneously, reduces the weight of heat exchanger tube.
Description
Technical field
The utility model relates to a kind of heat exchanger tube.
Background technology
In the industries such as current heat energy industry, petrochemical industry, heat transmission equipment is various in style, and many containing Korrosionsmedium kind, and in order to prevent corrosion, these heat exchanger tubes often adopt anti-corrosion alloy steel, but steel alloy price is high, and cost is high; Or adopt other coatings, but complex process, cost occupies Gao Bu little.
The corrosion resisting property of aluminium is good, and the light specific gravity of aluminium, compare steel of the same area, its weight and price are all lower than steel, and lined steel pipe, strengthens the intensity of heat exchanger tube greatly simultaneously, do not need the aluminium alloy adopting high price.
The cold-forming property of aluminium is superior, is easy at normal temperatures shape.And according to after GB/T4437.1-2000 " Al and Alalloy hot-extruded tube " technical conditions extrusion molding, be combined closely with lined steel pipe.
Summary of the invention
The utility model object is to provide a kind of efficient heat transfer anticorrosion heat exchanger tube, to realize the corrosion preventing heat exchanger tube, and augmentation of heat transfer simultaneously.It can solve the corrosion of heat exchanger tube preferably, and thermoexcell heat transfer.
The utility model is achieved through the following technical solutions:
A kind of efficient heat transfer anticorrosion heat exchanger tube, comprises lined steel pipe, it is characterized in that, closely wrap up hot-pressed aluminium fin protective layer outward at lined steel pipe.
Described hot-pressed aluminium fin protective layer comprises by the thin aluminium protective layer between the aluminium fin of hot-pressed formation and aluminium fin.
Technique effect of the present utility model is: hot-pressed aluminium fin protective layer can alleviate heat exchanger tube corrosion greatly, expands the heating surface area of heat exchanger tube, the heat transfer of thermoexcell simultaneously, reduces the weight of heat exchanger tube.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Icon illustrates: 1. lined steel pipe; 2. aluminium fin; 3. thin aluminium protective layer.
Detailed description of the invention
As shown in Figure 1, a kind of efficient heat transfer anticorrosion heat exchanger tube, comprises the lined steel pipe (1) of agent structure, closely wraps up aluminum pipe outward at lined steel pipe (1), by hot-pressed, aluminum pipe is processed into hot-pressed aluminium fin protective layer.Detailed process be aluminum pipe by hot-pressed formation aluminium fin (2), and still have the thin aluminium protective layer (3) of one deck between each aluminium fin (2), thin aluminium protective layer (3) can prevent corrosion by Enough; Aluminium fin (2) becomes the extended surface of heat exchanger tube simultaneously, augmentation of heat transfer greatly.Lined steel pipe (1) enhances the intensity of heat exchanger tube, and compared to anti-corrosion alloy steel and hard aluminium alloy, cost is lower, can reduce the production cost of heat exchanger tube.
In aluminium fin (2) process, preferred spiral is hot extruded into spiral aluminium fin, and make aluminium fin (2) Liancheng one like this, aluminium fin (2) intensity is higher, more not fragile.
In superheating process, high-corrosion medium skims over heat exchange pipe external surface, and non-aggressive medium passes in heat exchanger tube, abundant heat exchange.High-corrosion medium does not contact with lined steel pipe (1), prevents high-corrosion medium to the corrosion of lined steel pipe (1).Aluminium fin (2) becomes the extended surface of heat exchanger tube simultaneously, augmentation of heat transfer.
Claims (3)
1. an efficient heat transfer anticorrosion heat exchanger tube, comprises lined steel pipe, it is characterized in that, closely wraps up hot-pressed aluminium fin protective layer outward at lined steel pipe.
2. efficient heat transfer anticorrosion heat exchanger tube according to claim 1, is characterized in that described hot-pressed aluminium fin protective layer comprises by the thin aluminium protective layer between the aluminium fin of hot-pressed formation and aluminium fin.
3. efficient heat transfer anticorrosion heat exchanger tube according to claim 1, is characterized in that described aluminium fin is spiral aluminium fin.
