Description
Technical field
The utility model relates to a kind of photoelectricity architecture-integral hollow glass system, particularly a kind of hollow photovoltaic component.
Background technology
Double glazing is that one is combined by two-layer or compound glass, and the space between glass and glass is filled with air or other special gas is also hedged off from the outer world with high-intensity sealing glue.Save the requirement of the energy for building, double glazing is with its sound insulation, the irreplaceable superior function such as heat insulation and being widely used.The two glass light photovoltaic assembly of hollow is the BIPV product with double glazing building performance, is the glass outer of double glazing is replaced to two glass glued photovoltaic component.But there is a potential problem in the two glass light photovoltaic assembly of hollow, namely power generation performance and heat-proof quality are mutually restrict to a certain extent.Photovoltaic module can produce a large amount of heat in power generation process, if these heats can not be discharged in time, constitutes a threat to the generating efficiency of photovoltaic module and fail safe.In the arranging of terminal box, on the one hand, in order to attractive in appearance and prevent it to be destroyed in use, usual way terminal box is arranged between intermediate glass and bottom glass, and filling with sealant seals around it, to reach the object of hiding terminal box, but it is bad to result in terminal box radiating effect, easily make terminal box temperature too high, diode fails, affect the security performance of assembly, simultaneously due to the existence of terminal box, be equivalent in fluid sealant, introduce another medium, terminal box is sometimes hot and sometimes cold along with the power of component operation efficiency, fluid sealant can be made to expand with heat and contract with cold frequently, the life-span of fluid sealant will reduce greatly, steam will be caused to enter in assembly, affect the attractive in appearance of hollow device, seriously component failures can be caused.On the other hand, photovoltaic battery panel guide-wire tip goes out pole, and terminal box is arranged on a top end face of two glass photovoltaic module, relatively little with the contact-making surface of glass, cohesive force is between the two not strong, and this will make the installation of terminal box inconvenient and there is the not high shortcoming of fail safe.For this reason, find a kind of needs more reasonably going out the performances such as pole mode terminal box is easy for installation to meet, good heat dissipation effect, fail safe height and seem particularly important.
Summary of the invention
It is easy for installation, firm that the purpose of this utility model is to propose a kind of terminal box, the hollow photovoltaic component that thermal diffusivity, fail safe are high, solve the radiating effect that common terminal box mounting means exists bad, problem that is inconvenient, poor stability is installed.
A kind of hollow photovoltaic component, comprises the front layer glass 1, solar battery sheet 3, middle level glass 12 and the bottom glass 11 that are arranged in order, arranges parting bead 6 between described middle level glass 12 and bottom glass 11.
Described solar battery sheet 3 is bonded together with front layer glass 1 and middle level glass 12 respectively by the first doubling film 2 and the second doubling film 4.
Described parting bead 6 is connected on described middle level glass 12 and bottom glass 11 by butyl hot-melt is gluing.
The outside of described parting bead 6 adopts structure silica gel 5 to seal.
Described middle level glass 12, parting bead 6 and bottom glass 11 form cavity, and described cavity inside is filled with inert gas.
Drier is provided with inside described parting bead 6.Described drier is positioned in cell body 7.
The back side of described bottom glass 11 is provided with terminal box 8.Described terminal box (8) is bonded together by electric insulating sealant and bottom glass (5).
Described middle level glass 12 and bottom glass 11 opposite position have through hole separately, the positive and negative electrode lead-out wire of described solar battery sheet (3) is drawn from the through hole of middle level glass 12 respectively, through cavity, draw from the through hole of bottom glass 11 and connect together with described terminal box 8 inner terminal.Through-hole diameter size preferably just can make the lead-out wire being coated with insulating sleeve pass.
Described lead-out wire outer surface coated insulation sleeve pipe 9, the through hole perfusion fluid sealant 10 that described lead-out wire passes.
Described front layer glass 1 is low iron embossing toughened glass, and described middle level glass 12 and bottom glass 11 are general white toughened glass; Described solar battery sheet 3 is crystal silicon battery plate, and described first doubling film 2 and the second doubling film 4 are PVB.
Described photovoltaic module can be crystal silicon or membrane photovoltaic component; The backboard of photovoltaic module can be the ETFE material film of glass or high printing opacity; On backboard and glass, set through hole can arrange one or more as required;
The beneficial effects of the utility model are: the utility model adopts the mode offering circular hole on middle level glass and bottom glass to realize solar battery sheet being gone out polar curve and the connection being arranged on the terminal box in bottom glass back.Easy for installation, bonding with glass firm, the good heat dissipation effect of terminal box, decreases the risk that terminal box lost efficacy, also enhances its reliability and fail safe.
