Detailed Description
The following description of the embodiments with reference to the drawings is provided to describe the embodiments of the present invention, and the embodiments of the present invention, such as the shapes and configurations of the components, the mutual positions and connection relationships of the components, the functions and working principles of the components, the manufacturing processes and the operation and use methods, etc., will be further described in detail to help those skilled in the art to more completely, accurately and deeply understand the inventive concept and technical solutions of the present invention.
Full glass solar energy bi-pass thermal-collecting tube is double-deck vacuum tube, including inner tube 2 and outer tube 1, inner tube 2 and outer tube 1 seal at both ends to constitute the thermal-collecting tube with evacuation between inner tube 2 and the outer tube 1, in order to promote 2 heat-absorbing capacity of inner tube, the surface of inner tube 2 has the energy absorption layer, and the energy absorption layer adopts PVD physics meteorology deposit, with copper, aluminium, stainless steel molecule vacuum evaporation, the sputter ion mode is plated to inner tube 2 surfaces.
The inner pipe 2 and the outer pipe 1 can be formed by blowing and are independently processed, in order to improve the reliability of the inner pipe 2, a stress release belt is arranged at a position, which is inclined to one side, of the inner pipe 2, the rigidity of the inner pipe 2 can be prompted by the offset arrangement, through tests, the rigidity of the inner pipe 2 can be improved by more than 30% by the offset arrangement of the stress release belt compared with the stress release belt arranged at the middle position, and the optimal arrangement position is that the length of the inner pipe 2 at one side of the stress release belt is 20-40% of that of the inner pipe 2 at the.
As shown in figure 1, the stress release belt comprises a stress ring 3 and connecting pipes 4 which are connected with the inner pipe 2 at two sides of the stress ring 3, the stress ring 3 is of a tubular structure with the middle part arched outwards to form a revolving body with a C-shaped section, the shape of the revolving body is similar to that of a tire, and the energy absorption design can greatly improve the temperature resistance of the inner pipe 2 and the reliability of water stored in the inner pipe 2.
In order to promote the anti stress ability of interior outer tube 1, inner tube 2 and outer tube 1 are G3.3 borosilicate glass, and the wall thickness of pipe is 1.6mm, to the 2 wall thicknesses of inner tube of this size, the internal diameter of connecting pipe 4 is 25-45% of the 2 internal diameters of inner tube, and the external diameter of stress ring 3 is the same with 2 internal diameters of inner tube, then the cooperation stress ring 3 that can be better promotes inner tube 2 and endure dynamics, in addition, during the preparation of inner tube 2, stress ring 3, connecting pipe 4 need be coaxial.
In order to further improve the anti-stress capability of the inner pipe 1 and the outer pipe 1, the connecting pipe 4 is of a corrugated pipe structure, and has an energy absorption effect compared with the stress ring 3, the connecting pipe 4 also has an energy absorption effect, and the anti-stress capability of the inner pipe 2 can be greatly improved due to the matching effect of the connecting pipe 4 and the inner pipe.
The heat collecting pipes are fixed side by side to form the heat collector, and as the inner pipe 2 has strong adaptability, an arc-shaped reflector 5 can be arranged below each heat collecting pipe, so that the heat absorbing capacity of the inner pipe 2 can be greatly improved, and the temperature in the inner pipe 2 reaches more than 200 ℃.
