Description
Technical field
The present invention relates to a kind of device of solar generating, be specifically related to a kind of electrical integrated electricity generation module of photo-thermal based on solar energy acquisition thermo-electric generation technology.
Background technology
Solar energy is the clean and cheap energy, makes full use of it, and is significant.Existing solar energy collecting plate has plenty of plately, has plenty of columniform aggregate.Because the former misses many luminous energy to reflection of light and latter's intercolumniation space, causes a large portion luminous energy not to be utilized.
With transform light energy is the photovoltaic cell of electric energy, conversion efficiency lower (commercial prod is about 11%-13%); It is seriously in short supply with silicon materials to produce photovoltaic cell, and cost of manufacture is high and seriously polluted, and rate for incorporation into the power network is more than 10 times of coal electricity, and these factors all have a strong impact on and restricted the large-scale promotion of photovoltaic cell and use.
Summary of the invention
To the problem that exists in the above-mentioned prior art, the object of the present invention is to provide the electrical integrated electricity generation module of a kind of photo-thermal, it can make full use of solar energy, and thermoelectric transfer ratio is high, the corresponding lower and environmentally safe of cost of manufacture.
The technical scheme that the present invention is taked for its purpose of realization: the electrical integrated electricity generation module of a kind of photo-thermal, comprise module body, said module body is a three-decker, and the upper strata is a heat zone, and the centre is a thermal insulation layer, and bottom is a cryosphere; Said heat zone is the luminous energy Guinier-Preston zone, and its upper surface is laid several convex lens; Lay two kinds of plain conductors in heat zone, thermal insulation layer and the cryosphere of said convex lens below with different electric subnumber density; Both link and constitute a thermocouple; Its contact places heat zone and cryosphere respectively, and several thermocouples are composed in series a thermopile; Single convex lens thermopile corresponding with it constitutes a generator unit, and several generator units are through being in series or in parallel to form electricity generation module.
Said two kinds of plain conductors with different electric subnumber density are copper and constantan plain conductor, or platinum and platinum rhodium metal lead, or other are used to make the conductor with different electric subnumber density of thermocouple.
Said module body surface is the three-dimensional space curved surface that plane or concave-convex surface have diffuse reflective nature.
The material of said thermal insulation layer comprises asbestos or mineral wool.
Said cryosphere is the cavity of fluid-filled medium, and said fluid media (medium) comprises water or salt solution, and its temperature can be regulated and control as required; Or in the cavity of cryosphere the filling solid dielectric, like solid dielectric materials such as perlite, phenol formaldehyde foam polyurethane or alumina silicate.
As optimal design: said module body surface design is concavo-convex three-dimensional space curved surface with diffuse reflective nature.
Said heat zone is the cavity body structure, and inner surface is done blacking and handled, or filling heat-absorbing material in the cavity.
Photo-thermal electricity electricity generating principle:Irregular concave-convex curved surface design is adopted on the surface of module, has irreflexive characteristic, shines this curved surface sunlight everywhere, and except that absorbed luminous energy, some is reflected.The light that is reflected can drop on another place of this curved surface again, carries out that absorb the second time and reflection.The light of reflection for the second time can drop on another place of this curved surface again, absorbs for the third time and reflects.The luminous energy of reflection can be more and more littler each time.The luminous energy of initial incident is almost absorbed by this curved surface fully.In addition, on this daylighting curved surface, arrange a large amount of convex lens optically focused, strengthen the temperature difference of heat zone and cryosphere, thereby increase the energy output of thermopile.
To in the closed road that plain conductor is unified into, obtain steady current, must in circuit, have temperature gradient (temperature difference) and electron number density gradient (density contrast) simultaneously.So two kinds of metals are together in series; And their two contacts are placed heat zone and cryosphere respectively, in the loop that two kinds of plain conductors with different electric subnumber density constitute, thermo-electromotive force will appear; In the loop electric current will appear, thermoelectric effect that Here it is.Its principle is:
Free electron in the metal is like gas, and when in the metallic conductor during non-uniform temperature, free electron can produce thermal diffusion.This thermal diffusion effect can be regarded a kind of non-electrostatic force equivalently as.It moves free electron, in conductor, forms certain potential difference, because free electronic concentration eminence current potential is low, concentration lower current potential is high.Experiment shows, acts on the equivalent non-static(al) K on the unit charge, and its size is proportional to the gradient dT/dl (being the temperature difference of unit length) of temperature, and relevant with the character of metal material.The electromotive force of common metal thermoelectric couple is very little, is mostly millivolt (MV) level.In order to strengthen thermoelectric effect, except that selecting special metallic conductor for use and increasing the temperature difference, also many thermocouples are together in series, form thermopile (thermoelectric pile).This thermopile can be used as DC power supply.
Can be known by technique scheme: the present invention has improved the utilance to luminous energy, and experiment shows its energy output greater than with homalographic photovoltaic generation amount, and manufacturing cost is lower, and is pollution-free, is easy to penetration and promotion.Modularized design can by the building materials requirement (as watt, Wall brick etc.) manufacture and design, make it have daylighting, generating, heat insulation building materials function simultaneously.
