Abstract
The invention provides an enamel heat-insulation tube which comprises an inner-layer tube and an outer-layer tube. The inner-layer tube is made of metal materials, and the outer-layer tube is made of enamel materials. The enamel heat-insulation tube is low in cost and stable in heat-insulation performance, and is not easy to deform.
Description
Technical field
The invention belongs to the solar facilities application, refer to especially the enamel thermal insulation pipe.
Background technique
For some heat energy applications, such as the solar energy heat utilization, need to being delivered to other makes land used with producing from heating power with the heat transport medium (such as water or conduction oil) of high temperature.In this course of conveying, for preventing thermal loss, industry is usually at transfer canal outer wrapping multilayer insulant, as wrap up successively the protective coating of heatproof anticorrosive coat, heat insulation layer, polyurethane foam insulation layer and outermost at pipeline external, to reduce the heat exchange of pipeline internal medium and external environment, the deficiency of this kind structure is that heat insulation effect is very not desirable on the one hand, is complicate fabrication process on the other hand, is unfavorable for reducing manufacture cost.For this problem, industry is also developed the vacuum insulation tubular construction, specifically can be with reference to shown in the Chinese patent 02263826.1, but the sealing plate of this kind structure at the outer tube two ends is by sealing plate is welded on the outer tube, this kind mode is made comparatively difficult, also is unfavorable for reducing manufacture cost.
Summary of the invention
The object of the invention is to provide a kind of enamel thermal insulation pipe, the problem that existing thermal insulation pipe cost is higher in order to solve, deformation occurs greatly and easily manufacture difficulty.
To achieve these goals, the present invention proposes a kind of enamel thermal insulation pipe, comprises inner tube and external pipe, and the material of described inner tube is metal, and the material of described external pipe is enamel.
Optionally, described enamel surfaces scribbles black paint.
Optionally, the material of described inner tube is aluminum alloy.
Optionally, be provided with aerogel between described inner tube and the described external pipe.
Compared with prior art, the beneficial effect of enamel thermal insulation pipe of the present invention is: enamel thermal insulation pipe of the present invention is cheap, and thermal insulation property is stable, and is difficult for occuring deformation; Plate one deck black paint in the enamel outside, be conducive to heat absorption, thereby reduce scattering and disappearing of heat.
Description of drawings
Fig. 1 is the sectional view of enamel thermal insulation pipe of the present invention.
Fig. 2 is the sectional view of enamel thermal insulation pipe of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
At first; please refer to Fig. 1; Fig. 1 is the sectional view of enamel thermal insulation pipe of the present invention; as can be seen from Figure 1; the present invention proposes a kind of enamel thermal insulation pipe; comprise inner tube 10 and external pipe 11; the material of described inner tube 10 is metal, and the material of described external pipe 11 is enamel, because the enamel stable chemical performance; hardness is higher; therefore be not easy to occur chemical change and deformation, effectively protected inner tube 10 not to be damaged, in order further to improve heat insulation effect; between inner tube 10 and external pipe 11, aerogel can be set.Described enamel 11 surfaces scribble black paint.The material of described inner tube 10 is aluminum alloy.
Then, please refer to Fig. 2, Fig. 2 is the sectional view of enamel thermal insulation pipe of the present invention, and as seen from Figure 2, the outside of inner tube 10 is provided with one deck enamel 11 as outer tube.
Although the present invention discloses as above with preferred embodiment, the present invention is defined in this.Any those skilled in the art without departing from the spirit and scope of the present invention, all can make various changes or modifications, so protection scope of the present invention should be as the criterion with the claim limited range.
Claims (4)
1. an enamel thermal insulation pipe comprises inner tube and external pipe, and the material of described inner tube is metal, it is characterized in that: the material of described external pipe is enamel.
