Abstract

The utility model discloses a solar energy vacuum tube heat collection device which comprises a whole vacuum glass pipe. The inner part of the whole vacuum glass pipe is provided with a heat absorption fin, a heat collecting pipe and a selective absorption coating. The heat collecting pipe is tightly connected with the inner side of the heat absorption fin, and the selective absorption coating is plated at the outer side of the heat absorption fin. As the utility model adopts the structure, the inner wall of the whole vacuum glass pipe needs not be plated with films, so the processing process is simplified. Compared with the traditional form, the utility model decreases two heat exchanging thermal resistors, and greatly improves the heat exchange efficiency, and the effect is more obvious especially in the area with thin air.

Description

A kind of solar energy vacuum tube heat collector
Technical field
The utility model relates to solar energy heat utilization device, is specifically related to a kind of solar energy vacuum tube heat collector.
Background technology
Solar thermal collector is a kind of solar energy heat utilization device, can be used for adding media such as hot water, air.Multiple versions such as that present solar thermal collector mainly contains is flat, all-glass vacuum tube type and heat pipe-type.Cover U-shaped tube solar heat-collecting device structure is that heat absorption fin and thermal-collecting tube are installed in an all-glass vacuum tube in traditional all-glass vacuum tube, and plates one deck in order to absorb the coating for selective absorption of solar radiation at the double glazing inwall of vacuum tube.During use, solar radiation sees through all-glass vacuum tube and at first heats coating for selective absorption, heats inner air tube then, absorbs heat fin at last with medium in the heat transferred thermal-collecting tube with air heat again.But cover U-shaped tube solar heat-collecting device structure heat exchange thermal resistance is bigger in traditional all-glass vacuum tube, and heat exchange efficiency is lower, and poorer in comparatively thin its result of use of area of air.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of solar energy vacuum tube heat collector is provided, and it has improved heat exchange efficiency greatly, is particularly suitable for the rarefaction of air area and uses.
For achieving the above object, the technical solution of the utility model is as follows: a kind of solar energy vacuum tube heat collector, comprise the vacuum glass tube, and have heat absorption fin, thermal-collecting tube and coating for selective absorption in the vacuum glass tube; Described thermal-collecting tube closely is connected with the heat absorption fin is inboard, and coating for selective absorption is plated on the heat absorption fin outside.
Above-mentioned thermal-collecting tube can be the U-shaped pipe, also can be heat pipe.
Above-mentioned heat absorption fin ringwise.
The utility model is owing to adopt said structure, and its vacuum glass tube inwall need not plated film, has simplified manufacturing procedure; Compare with traditional form, reduced by two heat exchange thermal resistances, improved heat exchange efficiency greatly, especially more obvious in rarefaction of air area result of use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to cutaway view Amplified image;
Fig. 3 is the B portion amplification assumption diagram of Fig. 2.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model has a vacuum glass tube 1, be with the annular heat absorption fin 2 of metal manufacturing and the U-shaped thermal-collecting tube 3 of interior dress medium in the vacuum glass tube, U-shaped thermal-collecting tube 3 closely is connected with annular heat absorption fin 2 inboards, and annular heat absorption fin 2 outsides are coated with one deck coating for selective absorption 4.
When the utility model used, solar radiation penetrated vacuum glass tube direct irradiation on the heat absorption fin, then with the medium in the heat transferred U-shaped thermal-collecting tube.
In addition, above-mentioned U-shaped thermal-collecting tube can replace with the heat pipe of interior dress phase transition temperature material.
