Description

A kind of can self-cleaning high power concentrator photovoltaic module
Technical field
The new shape of this practicality relate to a kind of can self-cleaning high power concentrator photovoltaic module.
Background technology
Solar photovoltaic technology can be applicable to all trades and professions, is a kind of green energy resource of environmental protection and energy saving, also is to solve present environmental problem, advocates the effective measure of energy-saving and emission-reduction, thereby becomes the energy conversion of application prospect mode is arranged most.
The high power concentrator photovoltaic module, promptly solar cell is a third generation solar cell, and assembly is that the GaAs cell receiver is put into component internal and fixing, is equipped with Fresnel Lenses above, and the high multiple optically focused of scioptics has improved the service efficiency of light.And that the optically focused module will be placed on is outdoor, and is used for the module collar extension of inside and outside ventilation, can be because the deposition obstruction gradually of dust, impurity for a long time, and then influence the inside and outside gas flow of module, make the module internal gas pressure raise, the reduction battery conversion efficiency.In order to guarantee the operate as normal of module, there is the staff that it is cleaned and changes on time, this can increase the cost of care and maintenance photovoltaic module undoubtedly greatly.Therefore, the technology of existing die set haves much room for improvement and develops.
Summary of the invention
Deficiency to the prior art existence; The new shape technical problem to be solved of this practicality is; Provide a kind of and can improve contamination resistance; Be that photovoltaic generating system saves the cost of care and maintenance photovoltaic module, keep for a long time balance and the stable GaAs battery sheet of module inner and outer air pressure energy conversion efficiency, simple in structure, with low cost can self-cleaning high power concentrator photovoltaic module.
For solving the problems of the technologies described above; The technical scheme that the new shape of this practicality is taked is: a kind of can self-cleaning high power concentrator photovoltaic module; Comprise half ear shape shell and ventilating opening with inner chamber; At half ear shape outer casing bottom base plate is set, ventilating opening is provided with side plate, is provided with aeration structure on said base plate and the side plate; Surface at the medial surface of the lateral surface of said base plate and side plate is coated with the self-cleaning coating layer.
Above-mentioned can self-cleaning high power concentrator photovoltaic module, said aeration structure is set to wire side.
Above-mentioned can self-cleaning high power concentrator photovoltaic module, said base plate all is connected with half ear shape shell through bearing pin with side plate.
Above-mentioned can self-cleaning high power concentrator photovoltaic module, said base plate is all consistent with the lateral dimension of half ear shape shell inner cavity with the lateral dimension of side plate.
The new shape of this practicality can self-cleaning high power concentrator photovoltaic module advantage be: comprise half ear shape shell and one deck self-cleaning coating layer, these parts link to each other through silica gel with photovoltaic module, act in the system of photovoltaic generation.Base plate and side plate are the rough wire sides with nanoscale spacing, and on its surfaces coated self-cleaning coating.Because below the half ear shape shell is empty, has prevented the entering of rainwater, also played the effect of ventilation; And nano level hydrophobic layer has been installed on the part of described photovoltaic module; And coated self-cleaning coating, under the condition of illumination, titanium dioxide has the ability of good decomposing organic matter matter in the coating; Can effectively stop adhering to of materials such as airborne dust, mushroom; And then reached the self-cleaning purpose of assembly, and wire side high ventilation performance guaranteed the balance of assembly inner and outer air pressure, for the conversion efficiency that improves photovoltaic cell has played positive effect.
Description of drawings
Fig. 1 is the structural representation of the new shape half ear shape shell of this practicality;
Fig. 2 is the structural representation of base plate;
Fig. 3 is the structural representation of side plate;
Fig. 4 is the overall structure installation diagram of the new shape of this practicality.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the new shape of this practicality is explained further details;
Like Fig. 1,2,3, shown in 4; A kind of can self-cleaning high power concentrator photovoltaic module, comprise half ear shape shell 1 and ventilating opening 12 with inner chamber 11, in the bottom of half ear shape shell 1 base plate 2 is set; Side plate 3 is set on the ventilating opening 12, is provided with aeration structure 4 on said base plate 2 and the side plate 3; This aeration structure 4 is set to wire side with holes.Surface at the lateral surface of base plate 2 21 and the medial surface 31 of side plate 3 is coated with self-cleaning coating layer 5.Base plate 2 is rotatably connected with half ear shape shell, 1 formation through bottom bearing pin 22, side bearing pin 32 respectively with side plate 3.Base plate 2 is all consistent with the lateral dimension of half ear shape shell inner cavity with the lateral dimension of side plate 3.This coating has the ability of decomposing organic matter under the irradiation of ultraviolet-visible light, guaranteed the cleaning of ventilation place wire side.And the rough wire side of nanoscale; Its its specific structure can be utilized the lotus leaf effect principle; Form small hydrophobic projection on its coarse surface, when water droplet is in contact with it, form bigger contact angle; Can flow down with rainwater attached to this surperficial dust and oil smoke, realize self-cleaning effect.
Certainly, above-mentioned explanation is not to be the restriction to the new shape of this practicality, and the new shape of this practicality also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the new shape of this practicality, the variation of making, change shape, interpolation or replacement, all should belong to this practicality protection range of shape newly.
