According to the concentrating assembly and the preparation method thereof, the structure of the concentrating assembly in a solar high-concentration photovoltaic generating module can be promoted; and the concentrating assembly has ageing resistance and strong outdoor weather resistance, and is easy to clean.
Description
Technical field
The present invention relates to Fresnel Lenses and preparation method, the Fresnel Lenses concentrating component of saying so exactly and being used in the tempered glass protection, this component application is in the solar high power condense photovoltaic electrification module.
Background technology
The solar photovoltaic technology let us is enjoyed the clean reproducible energy that the sun gives; and a necessary important concentrating component is exactly the concentrating component that is formed by Fresnel Lenses in the solar high power condense photovoltaic electrification module; concentrating component structure in the existing sun energy high power condense photovoltaic electrification module; system adopts the sensitive surface of the Fresnel Lenses concentrating component of acrylic moulding directly to expose outside, does not have any protection.
As No. 201010146844.9, patented claim described " manufacture method of nanometer self-cleaning spotlight solar energy Fresnel lens ", this application discloses a kind of manufacture method of nanometer self-cleaning spotlight solar energy Fresnel lens, and this method is that an acrylic board is carried out the hot-forming Fresnel Lenses that one side has nano-micro structure that forms on hot-press base plate.Adopt this method can produce the Fresnel Lenses of nano-micro structure very easily, cost is lower, processes simple and convenient.The concentrating component of this method made still is the acrylic moulding, and is poor in outdoor weathe resistance, low, the easy loss of heatproof, damage easily, and tenure of use is short, and this is a serious problem concerning the long-term concentrating component that uses out of doors of needs.Often increase considerably the cost of solar concentrating photovoltaic power generation and reduce generating efficiency.
Summary of the invention
Based on this, the purpose of this invention is to provide a kind of improved Fresnel Lenses concentrating component and preparation method thereof, this concentrating component and preparation method thereof can promote the interior concentrating component structure of solar high power condense photovoltaic electrification module, and anti-aging, outdoor weathe resistance is strong, easy cleaning.
Another object of the present invention provides a kind of Fresnel Lenses concentrating component and preparation method thereof, this concentrating component and preparation method thereof combines with Fresnel Lenses by tempered glass, heatproof height, weatherability are good, indeformable, not yellow of concentrating component etc., tempered glass can effectively intercept solar ultraviolet, reaches long target tenure of use.
For achieving the above object, the present invention realizes like this.
A kind of Fresnel Lenses concentrating component, it is characterized in that described concentrating component has Fresnel Lenses, bonding coat and tempered glass, tempered glass is fixed on the Fresnel Lenses back side by bonding coat, the tempered glass assembly effectively partly isolates from the sunshine middle-ultraviolet lamp outside the glass, all the other light again via this Fresnel Lenses with the caustic surface of light-ray condensing in a precalculated position.
Bonding coat, be silica gel or other binder, its effect one is to have suitable stickiness, makes tempered glass and Fresnel Lenses stably fixing, the 2nd, do not influence the transmission of light in bonding coat, light can be injected into the Fresnel Lenses from tempered glass without barrier.Since or select the good binder of translucent effect for use, and perhaps select thin bonding coat for use, can reach does not influence the effect that light is injected.
A described Fresnel Lenses and a tempered glass, wherein, tempered glass is greater than Fresnel Lenses, described Fresnel Lenses is in single or array mode, bind or be fixed on the tempered glass, the formed optically focused spare of this Fresnel Lenses is bonding on the tempered glass basal surface and is formed with a plurality of first and penetrates incidence surface, and second exiting surface, and it is located at this tempered glass assembly below; By this, the Fresnel concentration structure lens of this acrylic moulding system vertically penetrates the incident ray of different angles.
Described Fresnel Lenses, it is consistent with the bonding coat size.
Described Fresnel Lenses is the acrylic material moulding, comprises member single or the array mode, binds or is positioned over processing procedure on the tempered glass, and wherein, each member is a ring texture.
A kind of method for making of Fresnel Lenses concentrating component, it is as follows to it is characterized in that the method comprising the steps of:
The used material of tempered glass, Fresnel Lenses and bonding coat is chosen in A, selection, and is made as prescribed level according to designing requirement;
B, gluing are coated adhesive glue equably with a surface of tempered glass;
C, bonding Fresnel Lenses are parallel to tempered glass with the constituent components of Fresnel Lenses and are positioned on the adhesive glue, fix.
Described method also comprises deaeration and curing schedule, described deaeration, and promptly the tempered glass that will be bonded with Fresnel Lenses with the vacuum machine carries out vacuum defoamation and handles; Described curing is that the tempered glass that is bonded with Fresnel Lenses after the deaeration is put into baking box again, carries out the high temperature heated baking, is cured, and Fresnel Lenses is securely fixed on the tempered glass.
Described tack coat is that silica gel binds mode, makes the Fresnel concentration structure lens subassembly of tempered glass and acrylic moulding tightly stick mode on tempered glass.
Among the described step B, earlier tempered glass is fixed with frame, carried out gluing again.
The present invention adopts the form of Fresnel Lenses and tempered glass combination, and tempered glass can effectively partly isolate from the sunshine middle-ultraviolet lamp outside the glass, all the other light again via this Fresnel Lenses with the caustic surface of light-ray condensing in a precalculated position.Can improve concentrating component structure in the solar high power condense photovoltaic electrification module by tempered glass, increase ageing resistance, make that its outdoor weathe resistance is strong, easy cleaning.
And it is easy, with low cost that the present invention realizes, can be widely used in the existing various solar photovoltaic spot light power generation process.
