Abstract
A kind of total reflection solar energy condenser lens, its light-concentrating material is made up of transparent solid material, the shape of its cross section is " V " word shape, there is a heat collector centre of " V " word shape, and two limits forming " V " word shape are formed along hypotenuse direction word order by some right angled isosceles triangles.The three-dimensional shape of these convex lens can be with the symmetry axis of described " V " word shape for axle center, and described " V " word shape is rotated 180 ° of circular three-dimensional shapes obtained around axle center.Also can be rectangle three-dimensional shape.Temperature during the present invention can obtain, manufacturing process is simple, and cost is low, not easily corrosion, long service life.
Description
Technical field
The present invention and a kind of total reflection solar energy condenser lens, belong to solar energy applied products.
Background technology
Now, the utilization of low-temperature solar energy water heater is close to universal, and the research direction of present people has pointed to the Solar use of medium and high temperature.Because solar radiation is to the thermal Finite of the earth, in being obtained by solar light focusing, temperature is effective method.The mode focused on has two kinds: first reflect focalization, and it two is Refractive focusings.Present reflect focalization great majority use metallic plate, there is the phenomenon that Long-Time Service produces corrosion.
Summary of the invention
In order to overcome the deficiency of existing reflect focalization device, the invention provides a kind of reflect focalization mirror, Long-Time Service not easily produces corrosion.
The technical solution adopted for the present invention to solve the technical problems is: a kind of total reflection solar light condenser, the light-concentrating material of described condenser is made up of transparent solid material, there is a heat collector centre, there is fixed support lower end, the shape of the cross section of described condenser is " V " word shape, and two limits forming " V " word shape are formed along hypotenuse direction word order by some right angled isosceles triangles.The three-dimensional shape of these convex lens can be with the symmetry axis of described " V " word shape for axle center, and described " V " word shape is rotated 180 ° of circular three-dimensional shapes obtained around axle center.The three-dimensional shape of these convex lens also can be keep the cross section of described " V " word shape constant, by the short transverse prolongation growth of described cross section along described cross section, and the rectangle three-dimensional shape that the distance extending growth obtains for height.The direction of the wide mouth above described " V " word shape is just to sunshine direction.When the direction of sunshine just to the wide mouth above " V " word shape, sunray has been irradiated on one of them right-angle side of " V " word shape each right angled isosceles triangle inner, owing to being just right, so the incidence angle of light and this right-angle side is 0, light keeps former direction to be mapped on the hypotenuse of right angled isosceles triangle, and the incidence angle that light and inclined-plane are formed is 45 °.If the transparent solid material forming " V " word shape is simple glass, its refractive index is 1.5, then inject on the interface of air at glass, the critical angle that light produces total reflection is 41 °, the critical angle that the 45 ° of incidence angles be mapped on inclined-plane due to solar irradiation are greater than 41 °, meet the condition producing total reflection, so, sunray reflects through hypotenuse, from another right-angle side outgoing, because light is 0 in the incidence angle of another right-angle side, so light keeps original direction after injecting air, be finally irradiated on the heat collector in the middle of " V " word shape.In order to alleviate weight of the present invention, in order to be more prone to processing, the transparent solid material forming " V " word shape can be lucite, and its refractive index, close to 1.5, can produce total reflection equally.Because large-area solar energy has focused on the heat collector of a small size by the method by optically focused, valuable middle temperature just can be obtained.
The invention has the beneficial effects as follows, temperature in can obtaining, manufacturing process is simple, and moulding by casting, high accuracy need not be needed like that to grind with other optical mirror slips, cost is low, not easily corrosion, long service life.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing 1 is cross-sectional structure figure of the present invention, the shape of the cross section of described condenser is " V " word shape, be made up of a limit 1 of " V " word shape and another limit 2 of " V " word shape, there is a heat collector 3 centre, heat collector 3 there are a delivery port 4 and water inlet 5, there is fixed support 6 lower end, and two limits of " V " word shape are formed along hypotenuse direction word order by some right angled isosceles triangles.Sunray, perpendicular through one of them limit of described right angled isosceles triangle, the hypotenuse of described right angled isosceles triangle produces total reflection, in another limit outgoing of described right angled isosceles triangle, is finally irradiated on heat collector 3.
Accompanying drawing 2 is specific embodiments of the present invention.Its shape is with the symmetry axis of the shape of cross section described in Fig. 1 for axle center, and the shape of described cross section rotates 180 ° of circular three-dimensional shapes obtained around axle center.In order to make the direction of the wide mouth of circular three-dimensional shape always just to the sun, fixed support 6 will be placed in solar energy automatic light tracking sun locating system.Now, the technical development of solar energy automatic light tracking sun locating system is very ripe.
Accompanying drawing 3 is another specific embodiments of the present invention.Its shape is with the shape invariance of cross section described in Fig. 1, and by the short transverse prolongation growth of described cross section along described cross section, the distance extending growth is the rectangle three-dimensional shape that height obtains.Heat collector 3 in Fig. 3 is oblong-shaped, and in like manner, in order to make the present invention just carry out long-time thermal-arrest to sunshine direction always, fixed support 6 will be placed in solar energy automatic light tracking sun locating system.
