Abstract
The utility model relates to the technical field of heat exchangers, in particular to a corrosion resistant heat exchange tube which applies to the heat exchangers. The corrosion resistant heat exchange tube comprises a heat exchange tube body, and is characterized in that the heat exchange tube body is mainly composed of a corrosion resistant inner layer and an easily-welding outer layer. Due to the fact that the heat exchange tube body is mainly composed of the corrosion resistant inner layer (mainly a titanium tube) and the easily-welding outer layer (mainly a cheap copper tube), even if a medium with strong corrosivity flows through the corrosion resistant inner layer, damages can not be caused, meanwhile, by adopting the easily-welding outer layer, cost of the corrosion resistant heat exchange tube is greatly reduced compared with all titanium tubes adopted in a heat exchange tube, welding of an outer wall of the heat exchange tube and external environment is facilitated, connection between heat exchange tubes are facilitated, and manufacture cost is reduced.
Description
Technical field
The utility model relates to technical field of heat exchangers, especially is a kind of corrosion-resistant heat exchanger tube that is applicable to heat exchanger.
Background technology
Have now and be applied in the heat exchanger tube on the heat exchanger, two kinds of styles are arranged, a kind of is heat exchange copper tube; It has the advantage that price is low, weldability is good, but has the deficiency of corrosion-resistant, when especially using as heat exchanger tube; In view of the medium that flows through its tube chamber; There is part to have stronger corrosivity, therefore, limited the use of heat exchanger tube to a certain extent; Another kind is a heat exchange titanium pipe, though it has the corrosion resistance height, and the advantage that thermal conductivity is good; But have price is rather stiff, the deficiency of weldability difference especially is when using as heat exchanger tube; Heat exchange titanium pipe and outside are not easy welding, and be even welded, also insecure; Cause separation easily, reduce the service life of heat exchanger greatly, and repair rate is high.
The utility model content
The purpose of the utility model is to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and reasonable for structure, both easy and outside weldings and firm welding, reliable, and the heat exchanger tube that cost is low, corrosion resistance is high.
The purpose of the utility model is to realize like this.
Corrosion-resistant heat exchanger tube comprises heat exchanger tube, it is characterized in that, said heat exchanger tube mainly is made up of corrosion-resistant internal layer and easy welding skin; This kind of heat exchanger tube makes into by corrosion-resistant internal layer (mainly referring to the titanium pipe) and is prone to welding outer (mainly referring to the copper pipe that price is lower) to constitute; Even be the stronger medium of corrosivity, can not cause damage when flowing through corrosion-resistant internal layer yet, to be prone to welding outer and use; Comparing cost with whole titanium pipe reduces greatly; Make things convenient for heat exchanger tube outer wall and outside weldings again, both helped the connection of heat exchanger tube, reduce its manufacturing cost again.
The purpose of the utility model can also adopt following technical measures to solve.
As a kind of embodiment wherein, the corrosion-resistant internal layer of said heat exchanger tube is titanium material layers or steel material layers; Certainly, also can be that other resistant material constitutes internal layer.The easy welding skin of said heat exchanger tube is the copper material layer, that is: common copper pipe is outer as heat exchanger tube.
The easy welding skin of said heat exchanger tube is set in corrosion-resistant inner layer outer surface and is fixed together through pressurization.
Outer and the corrosion-resistant interior series of strata of the easy welding of said heat exchanger tube are Integratively formed.
Said heat exchanger tube uses and when heat exchanger, is preferably tortuous shape; Certainly, heat exchanger tube can also be arranged to other shape, as: straight tube-like, U tubulose or other shape.
The beneficial effect of the utility model is following.
(1) use resistant material as internal layer in view of the heat exchange piping; Can prevent the higher medium of corrosivity when the tube chamber, touch inner tube layer and cause damage, heat exchanger tube skin then to adopt common material outer; As: copper is outer, and it has the advantage that weldability is good, cost is low.
Description of drawings
Fig. 1 is the utility model heat exchanger tube cross-sectional structure sketch map.
Fig. 2 is the A-A sectional structure sketch map of Fig. 1.
Fig. 3 is arranged in the heat exchanger shell for heat exchanger tube and curves the structural representation of tortuous shape.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As depicted in figs. 1 and 2, a kind of corrosion-resistant heat exchanger tube comprises heat exchanger tube 1, and said heat exchanger tube 1 mainly is made up of corrosion-resistant internal layer 12 and easy welding outer 11; Wherein, said corrosion-resistant internal layer 12 is the titanium material layers, and being prone to welding outer 11 is the copper material layer.
Said heat exchanger tube 1 inside and outside two-layer can be to be prone to welding outer 11 and corrosion-resistant internal layer 12 be fixed together through pressurization; Also can be to be prone to welding outer 11 to constitute integral body through being enclosed within corrosion-resistant internal layer 12 outer surfaces; Perhaps being prone to welding outer 11 is through Integratively formed with corrosion-resistant internal layer 12.
Said corrosion-resistant internal layer 12 also can be to adopt corrosion resistant steel matter to process.
As shown in Figure 3, said heat exchanger tube 1 is tortuous shape, and is arranged in the heat exchanger shell 2; Stretch out outside the heat exchanger shell 2 at heat exchanger tube 1 two ends, and fixing with heat exchanger shell 2 welding through being prone to welding outer 11.
