Description

Three glass photovoltaic and photothermal integral assemblies
Technical field
The present invention relates to photovoltaic and photothermal solar equipment technical field, especially relate to a kind of three glass photovoltaic and photothermal integral assemblies.
Background technology
In one's own profession in the industry, " double glass photovoltaic module " has become the big focus of photovoltaic industry one, the photovoltaic module that double glass photovoltaic modulies are made up of two sheet glass and battery, replaces organic material backboard and the aluminium mount structure of conventional photovoltaic assembly.Double glass photovoltaic modulies are almost waterproof, can be anticorrosive, weatherability is good with fire line, can be used for that high humility area, agriculture/fishing light is complementary, many Acid Rain Areas, high salt fog area etc., and structure is simple, appearance and size is little, life-span length.
But the shortcoming of double glass photovoltaic modulies and traditional photovoltaic module is also fairly obvious:Because silicon(Monocrystalline silicon, polysilicon)The wave-length coverage of battery spectral response is between 320-1100nm, the sunshine of its all band can not be used for photovoltaic generation, now apply the photoelectric transformation efficiency in agriculture/fishing light complementation field for most double glass crystal silicon cell photovoltaic modulies 12% about, another aspect photovoltaic cell is easily affected by the microenvironment factor of outside environmental elements and use and leads to photovoltaic efficiency decline and life-span to decline;Development and Production is exclusively used in solar energy power generating base both at home and abroad recently(Factory, field)Novel double-glazed photovoltaic module, on the basis of double glass photovoltaic modulies, have adjusted spacing and the density of photovoltaic battery panel, and the EVA film backboard using improved ultrawhite low light transmission, make the photovoltaic efficiency of assembly bring up to 17% about, but solar thermal utilization rate is still zero.
Solar light-heat power-generation is that luminous energy is changed into heat energy, then the technology being generated electricity by traditional thermodynamic cycle acting again, and solar energy power generating is solar irradiation on semiconductor p-n junctions, form new hole-electron pair, in the presence of p-n junction built in field, hole flows to p area by n area, and electronics flows to n area by p area, form potential difference, luminous energy is directly just changed into electric energy.Therefore, what photovoltaic generation produced is direct current, and solar light-heat power-generation generation is the alternating current the same with traditional thermoelectricity, more preferable with the matching of conventional Power Generation Mode and existing electrical network, can directly surf the Net.But, existing photovoltaic generation and solar thermal utilization even with nor form the effect of good 1+1 > 2, because the mode of photo-thermal power generation is the multiple rows of bending copper pipe using now mostly(Or other metal heat-conducting tubes)And be arranged under photovoltaic module, space is larger, and conducts heat for indirect type, and heat utilization efficiency is not high, and photovoltaic electrification component often damages because radiating is bad, and service life does not reach ideal range(≤ 15 years), how to solve the above problems and still suffer from certain difficulty.
Content of the invention
It is an object of the invention to overcoming the shortcomings of in above-mentioned prior art that photovoltaic and photothermal solar equipment exists, provide that a kind of that to be suitable for that solar light wave spectral region is wide, photovoltaic and photothermal generates electricity compatible is complementary, solar energy conversion ratio is high, three glass photovoltaic and photothermal integral assemblies that are extending the photovoltaic module life-span.
The technical problem to be solved in the present invention is adopted the technical scheme that:Three glass photovoltaic and photothermal integral assemblies include ultrawhite low steel wool surface glass, printing opacity EVA film, solar panel, interconnecting strip, busbar, white EVA film, glass back plate, thermal-arrest rubber cushion, glass film plates, plastic-aluminum combined insulation film and the securing member combining above-mentioned part being arranged in order from top to bottom;Described glass back plate, glass film plates, thermal-arrest rubber cushion and liquid medium form heat collector, described thermal-arrest rubber cushion includes framework, it is provided with spaced and the opening that staggers compartmentation strip in framework, framework is divided into S-shaped passage by compartmentation strip, is connected with some pipe joints penetrating glass film plates under described thermal-arrest rubber cushion.
Further, described securing member includes bolt, the first packing ring of bolt upper end, the step pad of bolt lower end, second packing ring, nut, described bolt passes through whole assembly being connected on photovoltaic and photothermal support by screw sleeve, that one end of described screw sleeve and step pad respectively penetrates assembly and be mutually fitted close.
Further, described pipe joint includes several admitting pipe joints and titting water outlet, and described pipe joint is penetrated the glass film plates of assembly and mated with the chamfering of glass film plates by sealing ring.
Further, the thickness of described ultrawhite low steel wool face safety glass is 1.8-3.2mm.
Beneficial effects of the present invention:Compared with prior art, 1, by the compatible integration of photovoltaic module and photo-thermal assembly, substantially increase the utilization rate of solar energy, electric heating overall efficiency reaches more than 60%;2nd, pass through to arrange S-shaped passage, exponentially improve the cooling of this assembly radiating and thermal-arrest endotherm area, not only effectively utilizes photo-thermal is lived and industrial production to generate electricity or to be directly used in, and S-shaped passage directly contact photovoltaic electrification component, provide effective radiating condition, extend the service life of photovoltaic module, up to more than 30 years;3rd, take away for other system because the heat of photovoltaic module is cooled down absorption in a large number by the liquid medium of photo-thermal assembly, so solar illuminating intensity can double(Focusing ratio is 2), then photovoltaic generation power can double, photovoltaic power generation quantity also can double;4th, pass through unique bolt fastening and glued joint the connected mode combining so that integral component can easy disassembling soon, easy to use, easy to maintenance, after useful life, recovery utilization rate height is up to more than 90%;5th, the production capacity storage in domestic glass market can be digested after producing in batches in a large number, driven the development of other industry.
