Abstract
The invention discloses a solar heat collector which comprises an outside pipe (1) and an inside pipe (2). The section of the outside wall of the outside pipe (1) is in a round shape, and the section of the inside wall is in the shape of a polygon. The invention has the lens focusing effect, high heat collection efficiency, simple structure, technical easy realization and convenient transformation implementation, is fast heated, and has favorable market popularization using value.
Description
Technical field
The present invention relates to a kind of thermal-collecting tube, particularly a kind of solar energy heat collection pipe.
Background technology
The prior art solar energy heat collection pipe is generally the dual-layer vacuum glass pipe, sunlight sees through outer tube and shines interior pipe, heat transfer medium in the heating in the pipe, the inside and outside wall of outer tube is circle, angle did not change after light saw through outer tube, heat transfer medium in the effect that does not have optically focused, interior pipe is heated and relatively disperses, and it is slow to heat up, heat transfer rate is also slow, for overcoming this shortcoming, people have designed the thermal-collecting tube with convex lens structures, mainly contain two kinds of structures, a kind of is to increase in the outside of existing thermal-collecting tube to be provided with convex lens, be radiated on the thermal-collecting tube after making light by convex lens optically focused, a kind of is that convex lens structures directly is set on thermal-collecting tube, makes light focusing, produce quick heating, the fireballing effect of thermal-arrest, but improved technology ubiquity structure is complicated, and the shortcoming that cost of manufacture is big has influenced applying of technology.
Summary of the invention
The object of the present invention is to provide a kind of above-mentioned shortcoming that overcomes, both had the lens light gathering effect, solar energy heat collection pipe simple in structure again, that cost of manufacture is low.
The present invention is achieved in that a kind of solar energy heat collection pipe, comprises outer tube and interior pipe, and the outer wall cross sectional shape of this outer tube is circular, and inner wall section is shaped as polygon.
As a further improvement on the present invention, the inner wall section of this outer tube is shaped as regular polygon or irregular polygon.
Operation principle of the present invention is: the circular outer wall of thermal-arrest outer tube and polygon inwall are equivalent to form a plurality of convex lens, be equivalent to form convex lens between polygonal every limit and the corresponding outer wall arc section, when seeing through outer tube, sunlight can produce spotlight effect, heat transfer medium in making in the pipe is concentrated and is heated, and reaches the technique effect fast, that heat conduction velocity is fast, collecting efficiency is high that is heated.Simultaneously, the present invention is simple in structure, makes easily, only need on the basis of prior art thermal-arrest outer tube, increase by one polygon treatment process and get final product, realize easily in the making outer tube wall, small investment, cost of manufacture is low, possesses good marketing using value.
Description of drawings
Fig. 1 is the cross section view of first kind of embodiment of the present invention.
Fig. 2 is the cross section view of second kind of embodiment of the present invention.
Among the figure: 1, outer tube, 2, interior pipe.
The specific embodiment
As shown in Figure 1, the outer wall cross sectional shape of outer tube 1 is circular, inner wall section is shaped as octagon, be equivalent to form convex lens between every straight flange of inwall and the outer wall corresponding circle segmental arc, article eight, the limit is equivalent to form eight convex lens, when solar radiation is to outer wall, on every section arc section, produce the convex lens spotlight effect, that concentrates relatively shines on the interior heat transfer medium of managing in 2, heat transfer medium heated part temperature rises fast, big with the peripheral heat transfer medium temperature difference, it is also fast that heat exchanges conduction of velocity, the heat absorption efficiency height.
Shown in Figure 2 and difference Fig. 1 is that outer tube 1 inner wall section is shaped as irregular octagon, the length of side of light accepting part position, and the limit at position backlight is short, can better produce the spotlight effect of convex lens.When mounted, present embodiment has the direction requirement.
Compared to existing technology, clear superiority of the present invention is simple in structure, realizes easily on the technology, increases by one treatment process to outer tube 1 inwall and get final product on the prior art basis, and technological transformation less investment, technical transform are implemented to be easy to.
In the illustrated embodiment, outer tube 1 inwall is an octagon, during practical application, according to thermal-collecting tube thickness and effect, can be designed as the polygon of other number.
Claims (3)
1, a kind of solar energy heat collection pipe comprises outer tube (1) and interior pipe (2), it is characterized in that: the outer wall cross sectional shape of this outer tube (1) is for circular, and inner wall section is shaped as polygon.
2, solar energy heat collection pipe according to claim 1 is characterized in that: the inner wall section of this outer tube (1) is shaped as regular polygon.
3, solar energy heat collection pipe according to claim 1 is characterized in that: the inner wall section of this outer tube (1) is shaped as irregular polygon, the length of side of sensitive surface, and the limit of shady face is short.
