Abstract
The utility model provides an inside-light gathering glass evacuated solar collector tube which is formed by an inner tube, an outer tube and an elastic support rack arranged between the inner and the outer tubes, wherein the inner and the outer tubes are both made of double layers of glass. The glass evacuated solar collector tube is characterized in that the inner wall or the outer wall of the inner tube is plated with a light absorbing coating used for absorbing sunlight; and a light reflecting coating is arranged or a light reflecting film is stuck to the inner wall or the outer wall of the outer tube below the median diameter to form a light reflecting surface. In the technical scheme provided by the utility model, the outer tube adopts double-layered coatings on semi-peripheral wall, part of the sunlight entering the area of the outer tube is directly absorbed by the inner tube and the other part is reflected by the light reflecting surface at the lower part of the outer tube into the inner tube to be absorbed, therefore, the light gathering efficiency of the evacuated solar collector tube is greatly improved.
Description
Technical field
The utility model relates to light collecting vacuum heat collection pipe in a kind of full glass, belongs to the solar energy heat collection pipe technical field.
Background technology
What have the used vacuum tube of vacuum pipe solar water heater now all is glass tube, the structure of glass-vacuum tube is most and thermos flask is approximate, promptly two blind pipes are nested in together, the upper end sealing, be coated with absorption film on the inner tubal wall, the shortcoming of this structure is that the insulation after the interior pipe heat absorption only relies on by means of vacuum heat-insulating layer, and insulating efficiency haves much room for improvement.
Summary of the invention
The purpose of this utility model is to provide light collecting vacuum heat collection pipe in a kind of full glass, and vacuum tube increases the reflecting layer outside, to improve the insulating efficiency of vacuum tube.
The technical solution of the utility model is achieved in that light collecting vacuum heat collection pipe in this golden glass, constitute by the elastic support support that is provided with between pipe, outer tube and interior pipe, the outer tube in the double-glass vacuum, it is characterized in that: inner tube wall or outer wall are coated with light-absorbing coating in order to absorb sunlight, and following inwall in footpath or outer wall are provided with reflecting coating or paste reflective membrane and form reflective surface in the outer tube.
Light collecting vacuum heat collection pipe in the described full glass, described elastic support is arranged at an end of thermal-collecting tube.
The technical solution adopted in the utility model, because outer tube adopts half cycle wall reflective coating film, a sunlight part that enters the outer tube zone is directly absorbed by interior pipe, and pipe absorbed in the reflective surface of another part below outer tube reflexed to, thereby can improve the collecting efficiency of vacuum heat collection pipe greatly.
Description of drawings
Fig. 1 is the generalized section of light collecting thermal-collecting tube in the full glass of the utility model
Fig. 2 is the A-A view of Fig. 1
Among the figure: 1, outer tube 2, interior pipe 3, elastic support 4, reflecting coating
The specific embodiment
Fig. 1 is the structural representation of light collecting vacuum heat collection pipe in the full glass of the utility model, innovative point is that outer tube 1 lower peripheral wall at double-deck solar energy vacuum tube is provided with reflecting coating 4, and reflecting coating can directly apply, plating, chemical plating are on tube wall or post reflective membrane at tube wall and form reflective surface; The inwall of interior pipe 2 or outer wall are coated with light-absorbing coating in order to absorb sunlight, and a sunlight part that enters the outer tube zone is directly absorbed by interior pipe, and pipe absorbed in the reflective surface of another part below outer tube reflexed to, thereby can improve the collecting efficiency of vacuum heat collection pipe greatly.
The end that elastic support 3 is fixed on vacuum tube as shown in Figure 2.
Foregoing description only proposes as the enforceable technical scheme of light collecting vacuum tube thermal-collecting tube in the full glass of the utility model, not as the single restrictive condition to its structure itself.
Claims (2)
1. light collecting vacuum heat collection pipe in the full glass, support formation by the elastic support (3) that is provided with between double-glass vacuum inner and outer pipe (2,1) and the inner and outer pipe, it is characterized in that: interior pipe (2) inwall or outer wall are coated with light-absorbing coating in order to absorb sunlight, and following inwall in footpath or outer wall are provided with reflecting coating (4) or paste reflective membrane and form reflective surface in the outer tube (1).
2. light collecting vacuum heat collection pipe in the full glass according to claim 1, it is characterized in that: described elastic support (3) is arranged at an end of thermal-collecting tube.
