Abstract
The utility model discloses a heat transfer pipe, in particular to an alloy steel tube which is lower in manufacturing cost and has high strength. The alloy steel tube comprises a cylindrical tube main body; the tube main body comprises a steel inner body (1) and copper layers (2); and the copper layers (2) cover on the outer surface and the inner surface of the steel inner body (1). The alloy steel tube has the beneficial effects that the copper layers cover on the outer surface and the inner surface of the steel inner body, so that not only is the used amount of copper saved and is the production cost reduced while high heat conductivity is maintained, but also the strength is greatly improved.
Description
Technical field
The utility model relates to a kind of heat conduction tubing, relates in particular to a kind of alloy steel pipe that fabricating cost is lower and intensity is high.
Background technique
Heat exchange claims again heat exchange, refers to that heat energy is from hot fluid indirect (for example passing through partition) or the direct process that passes to cold fluid.For the efficient that improves heat exchange, because character is complicated, not only to consider the heat conduction through partition, and will consider the heat transfer by convection of partition fluid on both sides, sometimes also must consider radiative heat transfer.
At present on the market, because copper has very high thermal conductivity, the tubing that is used for heat exchange generally all is to adopt copper product, and its fabricating cost is higher, and bulk strength is inadequate, mutability.
The model utility content
The purpose of this utility model is to provide a kind of alloy steel pipe, solves the tubing fabricating cost that is used at present heat exchange too high, and the insufficient strength problem.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of alloy steel pipe comprises columniform main body, and described main body is to be made of steel endosome and copper layer, and described copper layer covers outer surface and the internal surface of steel endosome.
The beneficial effect that adopts technique scheme to produce is: outer surface and the internal surface of the utility model steel endosome all are coated with the copper layer, the consumption of not only having saved copper when keeping high thermoconductivity has reduced cost of production, and intensity also is greatly improved.
Description of drawings
Fig. 1 is the cross-sectional view of a kind of alloy steel pipe of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1: a kind of alloy steel pipe, comprise columniform main body, described main body is to be made of steel endosome 1 and copper layer 2, described copper layer 2 covers outer surface and the internal surface of steel endosome 1, outer surface and the internal surface of the utility model steel endosome 1 all are coated with copper layer 2, the consumption of not only having saved copper when keeping high thermoconductivity has reduced cost of production, and intensity also is greatly improved.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", " preferred embodiment " etc., the specific features, structure or the characteristics that refer in conjunction with this embodiment's description are included among at least one embodiment of the application's generality description.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiments this feature, structure or characteristics also drop in the scope of the present utility model.
Claims (1)
1. an alloy steel pipe comprises columniform main body, it is characterized in that: described main body is to be made of steel endosome (1) and copper layer (2), and described copper layer (2) covers outer surface and the internal surface of steel endosome (1).
