Description
Technical field
The present invention relates to a kind of solar-energy conversion systems, be specifically related to a kind of concentrating solar converting system that comprises paraboloidal mirror, light-guiding pillar and infrared rays receiver.
Background technology
Solar energy is a kind of more satisfactory energy, be widely used, volume ratio due to the sun and the earth, and the distance of the sun and the earth, the sunlight that people use can be regarded as collimated light beam, if directly utilize this collimated light beam to carry out the solar energy conversion, effect is general, preferably can assemble parallel sun light beam, can improve the solar energy conversion efficiency.
Paraboloidal mirror can be used for focusing on collimated light beam (sunlight), and when the collimated light beam of incident was parallel to the main shaft of paraboloidal mirror, collimated light beam can be focused on the focus of paraboloidal mirror.Therefore paraboloidal mirror is widely used.
Focused beam after paraboloidal mirror focuses on sometimes can not directly be used, and need to be transferred to infrared rays receiver by light-guiding pillar, thereby make collimated light beam finally be gathered in infrared rays receiver.
Light-guiding pillar be exactly with light with the loss of minimum from a light sources transmit to the device apart from another point of this light source certain distance.Light is to rely on total internal reflection in the light-guiding pillar internal transmission.
Light-guiding pillar generally comprises the light input that receives incident ray, and the light output end of output light.The light input generally comprises the plane of incidence, and light output end generally comprises exit facet.Light-guiding pillar also comprises the reflecting surface for internal transmission light.
Incident light enters light-guiding pillar by the plane of incidence, generally can reflect.Particularly for focused beam, each light in light beam is different at the incident angle of the plane of incidence, and light beam can complicated refraction occur at the plane of incidence when entering light-guiding pillar, be unfavorable for the propagation of light in light-guiding pillar.When serious, even in light beam, some light can form total reflection at the plane of incidence, can't enter light-guiding pillar, thereby loses the entrained information of this part light and energy.
And when light-guiding pillar was used for transmission white light (particularly sunlight), because white light (sunlight) is comprised of multiple monochromatic light, even various monochromatic light is identical in the incidence angle of the plane of incidence, but the refraction angle generally can be different, can cause dispersion; When serious, even some monochromatic light can form total reflection at the plane of incidence, can't enter light-guiding pillar, thereby loses the entrained information of this monochromatic light and energy.
Summary of the invention
the object of the present invention is to provide a kind of concentrating solar converting system, it can focus on parallel sun light beam, make collimated light beam form focused beam, and prevent from or reduce focused beam at the plane of incidence of light-guiding pillar, complicated refraction occuring, and then make the complete light-guiding pillar that enters of focused beam, prevent that in focused beam, some light is lost by total reflection at the light input of light-guiding pillar, guarantee that entrained information and the energy of focused beam can effectively enter light-guiding pillar, and effectively conduction in light-guiding pillar, and finally be transferred to infrared rays receiver, thereby improve the solar energy conversion efficiency of infrared rays receiver.
For achieving the above object, technical scheme of the present invention is a kind of concentrating solar converting system of design, comprises paraboloidal mirror, light-guiding pillar and infrared rays receiver;
Light-guiding pillar comprises the first leaded light piece and the second leaded light piece with identical refractive index;
The first leaded light piece, its geometry are the part between cross section and bottom surface of being positioned at that stays after a positive rectangular pyramid is cut by the first plane, and this bottom surface is positive rectangular pyramid bottom surface; Described the first plane is parallel with one side of bottom surface, and the angle of the first plane and bottom surface is the 35-55 degree; Described kernel of section to the distance of bottom surface be the bottom surface length of side 3-15 doubly; Each side of described positive rectangular pyramid and the angle of bottom surface are more than or equal to 89 degree;
Described cross section comprises the cross section first side parallel with the bottom surface and cross section Second Edge, and the cross section first side is larger to the distance of bottom surface than cross section Second Edge to the distance of bottom surface;
Described positive rectangular pyramid comprises four sides: comprises the first side of cross section first side, comprises the second side of cross section Second Edge, and the 3rd side and the 4th side;
The second leaded light piece, its solid are enclosed by following five bread and form: described cross section, the second plane, the face of cylinder, the 3rd plane, place, side, and the 4th plane, place, side; Described the second plane is vertical with described cross section, and comprises the cross section first side; The described face of cylinder is take the intersection on the second plane and the 3rd plane as axis, and the face of cylinder comprises the cross section Second Edge; Described the 3rd plane is perpendicular to the bottom surface, and comprises positive rectangular pyramid summit and bottom center, and parallel with the cross section first side;
The first leaded light piece and the second leaded light piece are take described cross section as faying face;
The first leaded light piece is fixedly connected with the second leaded light piece, and perhaps the first leaded light piece and the second leaded light piece are one-body molded;
The reflective surface of described paraboloidal mirror is relative with the face of cylinder, and the focus of paraboloidal mirror is positioned on the axis on the face of cylinder; The angle on the main shaft of described paraboloidal mirror and the second plane is 24 degree;
The sensitive surface of described infrared rays receiver contacts with the bottom surface of the first leaded light piece;
Infrared rays receiver comprises photoelectric conversion device and photothermal conversion device.
In more detail, the face of cylinder is a cylindrical side, this cylinder take perpendicular to the bottom surface and comprise positive rectangular pyramid summit and bottom center and the intersection on the face parallel with the cross section first side and the second plane as axis, cylindrical side comprises the cross section Second Edge.
Light-guiding pillar is take the face of cylinder (being positioned at cross section and the second interplanar) of the second leaded light piece as the plane of incidence, take the bottom surface (being positive rectangular pyramid bottom surface) of the first leaded light piece as exit facet.(first side that comprises the cross section first side, four sides of the first leaded light piece, the second side that comprises the cross section Second Edge, and the 3rd side and the 4th side), second plane (being positioned between cross section and the face of cylinder) of the second leaded light piece is the main reflecting surface of light-guiding pillar.
