Description
Technical field
The utility model relates to photoelectricity and building materials field, is specifically related to a kind of self radiation type BIPV photovoltaic module.
Background technology
Solar energy is a kind of green energy resource, its have clean, efficiently, never exhausted and not by plurality of advantages such as region restrictions, it can be widely used in every field, such as technical field of photovoltaic power generation.BIPV and BuildingIntegratedPV is BIPV.PV and Photovoltaic.BIPV technology is that solar power generation (photovoltaic) product is integrated into architectural technology.BIPV (BIPV) is different from the form that photovoltaic system is attached to architectural (BAPV:uildingAttachedPV).In modernized society, the pursuit of people to comfortable building thermal environments is more and more higher, causes the energy consumption of building and heating and air-conditioning growing.In developed country, energy for building has accounted for the 30%-40% of national total energy consumption, defines certain restrictive function to economic development.
Chinese patent Authorization Notice No. CN203983303U, authorized announcement date is that the utility model on December 3rd, 2014 discloses a kind of BIPV battery component, after described BIPV battery component is stacked by toughened glass, PVB glued membrane, crystal silicon cell, PVB glued membrane, toughened glass, heat and vacuumize, pressurize, solidify, encapsulation is formed.
BIPV photovoltaic module is a kind of BIPV product, can be integrated into architectural by solar power generation (photovoltaic) product.Its defect is: heat insulating ability is poor, and intensity is low, is difficult to the position such as forms, ceiling being applied in skyscraper.By gluing together heat insulation glass at BIPV photovoltaic module backlight side PVB or EVA, intensity and the heat-insulating property of BIPV photovoltaic module can be increased.Due to the poor thermal conductivity of heat insulation glass, when BIPV photovoltaic module heat is too high, because producing " temperature stress ", nature can occur with the heat insulation glass of its gummed and burst, the useful life of product is short.
Summary of the invention
The purpose of this utility model is the shortcoming and defect overcoming prior art, provides a kind of and can independently dispel the heat, the self radiation type BIPV photovoltaic module of long service life.
For realizing above object, technical solution of the present utility model is: a kind of self radiation type BIPV photovoltaic module, comprise glass back plate and glass outer, some cell pieces connected by interconnector are provided with between described glass back plate and glass outer, be tightly connected by the doubling that is bonded and sealed between glass back plate and glass outer, described glass back plate is fixed with terminal box, it is characterized in that: in the doubling that is bonded and sealed between described cell piece, be provided with wind passage, the intersection crossing wind passage is provided with ventilation hole, the outlet of described ventilation hole lays respectively at the surface of glass back plate and glass outer, the aperture of ventilation hole is provided with respiratory membrane.
The material of described respiratory membrane is expanded PTFE.
The inside of described terminal box is provided with two two row 15A bypass diodes.
Described cell piece is corner light-permeable cell piece.
Described interconnector is SAC band.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model can by the heat Quick diffusing of assembly inner generation in power generation process to extraneous by the wind passage excessively and ventilation hole spreading all over component internal, avoid because of accumulated temperature cause the damage of assembly, the respiratory membrane of opening ventilation hole can stop entering of rainwater dust while ventilative, ensure that the cleanliness factor of channel interior.
2, in the utility model, junction box has two two to arrange 15A bypass diode, after certain string in assembly is sheltered from heat or light or lost efficacy, for tandem provides bypass channel, avoids the economic loss because inefficacy tandem causes.
3, the cell piece in the utility model can increase light transmittance due to its corner, and compared with the polycrystalline cell piece of same efficiency, its glazed area can increase by 2.83%.
