Abstract
The invention provides a plane mirror combination condensation module, comprising a type plane substrate and a plurality of plane mirrors mounted on the substrate, wherein each plane mirror is provided with an inclination direction and an angle relatively to the type plane substrate. When assembles the plane mirror combination condensation module and a solar light receiver into a condensation generator, each plane mirror of the plane mirror combination condensation module can condense the incident solar light to the outer surface of the solar light receiver, and the solar light condensed at the outer surface of the solar light receiver is in the form basically consistent to the outer surfaced of the solar light receiver. The plane mirror combination condensation module improves condensation powers, has uniform light intensity distribution and has low demand on the accuracy of trackers. In the assembly of a plane mirror combination condensation generator, the overall design of the plane mirror combination condensation generator can be simple and modularized, having simple and fast installment.
Description
Technical field
The present invention relates to a kind of device of solar generating, relate in particular to a kind of combination concentration module of plane reflecting mirror that is used to make condenser.
Background technology
Concentrating solar photovoltaic generating can reduce the photovoltaic generation cost significantly.Along with improving constantly of new and effective concentrator cell efficient, concentrating generating system will be more and more important in the solar energy power generating field.Light-gathering optics has various ways, and main application is parabolic reflector formula point focusing system at present, and the advantage of this unit is: simple in structure, easy to maintenance; Be convenient to upgrading (can change more high efficiency battery); Light concentrating times variable (can realize multiple array mode) by changing class plane reflection mirror unit; Cost low (the catoptron cost is low, and light concentrating times can be very high, to the demand minimizing of battery).But following shortcoming is arranged also: the one, when adopting long focus reflector, light intensity is more even relatively, but very high to the tracking accuracy requirement, and the length of focal length is subjected to the restriction of the sunshine angle of divergence (+/-0.26 degree); The 2nd, when adopting weak point focal length catoptron, light intensity is seriously inhomogeneous, but lower to the tracking accuracy requirement, needs the secondary optical system of complexity this moment, and with the homogeneity of raising light intensity, but its effect is limited.
Summary of the invention
Purpose of the present invention is to solve the problems referred to above that prior art exists, and a kind of combination concentration module of plane reflecting mirror is provided.
The object of the present invention is achieved like this: a kind of combination concentration module of plane reflecting mirror, comprise the class planar substrates and be installed in suprabasil a plurality of plane mirror, each plane mirror has certain vergence direction and angle respectively with respect to the class planar substrates, when combination concentration module of plane reflecting mirror and sunlight receiver are assembled into concentrating generation device, each plane mirror in the combination concentration module of plane reflecting mirror all can converge to the sunshine of incident the outside surface of sunlight receiver, and the sunshine that converges to the sunlight receiver outside surface has the shape with sunlight receiver outside surface basically identical.
The bottom surface of described class planar substrates is the plane, the installed surface that is used for the mounting plane catoptron has the display of being made up of a plurality of declining lugs, and the vergence direction of the dip plane of each declining lug and angle are suitable with the vergence direction and the angle of each plane mirror respectively.
Described class planar substrates is by the compression moulding of special-purpose light high-intensity compound substance one.
Described a plurality of plane mirrors big or small identical.
Varying in size of described a plurality of plane mirrors.
When combination concentration module of plane reflecting mirror of the present invention and sunlight receiver are assembled into concentrating generation device, the hot spot that each plane mirror in the combination concentration module of plane reflecting mirror all can pool the sunshine of incident with receiver area basically identical is radiated on the receiver, the onesize hot spot of a plurality of such small reflector reflections overlaps on receiver, thereby has improved light concentrating times.The beam intensity ratio that converges on the receiver of each plane mirror is more even like this, and, when the hot spot that is converged by a plurality of such plane mirrors was overlapping on receiver, the surface error of individual mirror was very little to light distribution unevenness influence total on the receiver.The distance of catoptron and receiver is short more, and is low more to the requirement of mirror surface precision, also low more to the accuracy requirement of tracker simultaneously.Because the substrate of condenser is the class flat shape, and adopt the compression moulding of light high-intensity compound substance one, firm in structure, light durable, and be easy to install.
Description of drawings
Fig. 1 is the basic structure synoptic diagram of combination concentration module of plane reflecting mirror of the present invention;
Fig. 2 is the structural representation of the class planar substrates among the present invention.
Embodiment
Referring to Fig. 1, Fig. 2, combination concentration module of plane reflecting mirror of the present invention comprises class planar substrates 1 and is installed in suprabasil a plurality of plane mirror 2.
Referring to Fig. 2, the bottom surface 11 of the class planar substrates 1 among the present invention is the plane, the installed surface 12 that is used for the mounting plane catoptron has the display of being made up of a plurality of declining lugs 121, the dip plane of each declining lug 121 has different vergence directions and angle respectively, so that each plane mirror mounted thereto also has different vergence directions and angle.When combination concentration module of plane reflecting mirror and sunlight receiver are assembled into concentrating generation device, can guarantee that each plane mirror in the combination concentration module of plane reflecting mirror all can converge to the sunshine of incident the outside surface of sunlight receiver, and the sunshine that converges to the sunlight receiver outside surface has the shape with sunlight receiver outside surface basically identical.
Class planar substrates 1 among the present invention is by the compression moulding of special-purpose light high-intensity compound substance one.Can accomplish firm in structure, light durable like this, and be easy to install.
The size of a plurality of plane mirrors among the present invention can be identical, also can be inequality.
When combination concentration module of plane reflecting mirror of the present invention is used to make condenser, one can be adopted, also a plurality of combinations can be adopted.The condenser that adopts combination concentration module of plane reflecting mirror of the present invention to make can make the dilatation at double of optically focused energy, is convenient to system upgrade and regenerates.
