The utility model discloses a solar light-condensing structure of an optical thin film material. The solar light-condensing structure comprises a Fresnel lens and toughened glass, wherein the Fresnel lens is attached to and fixed on the toughened glass; and the Fresnel lens and the toughened glass form the solar light-condensing structure. During manufacturing of the solar light-condensing structure, silica gel is coated on the surface of the toughened glass and then shaped like the Fresnel lens by using a mold. According to the solar light-condensing structure, the ageing resistance, outdoor weather resistance and the like of a light-condensing component structure in a solar high-power light-condensing photovoltaic generation module can be improved, the cost of solar high-power light-condensing photovoltaic generation can be reduced, and the service life is prolonged.

Description

The Salar light-gathering structure of optical thin film material

Technical field

The utility model relates to solar concentrating photovoltaic power generation equipment, a kind of concentrating component structure in the solar high power condense photovoltaic electrification module that is used for of saying so exactly.

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 ability 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.

Like No. 201010146844.9, patented claim described " manufacturing approach of nanometer self-cleaning spotlight solar energy Fresnel lens "; This application discloses a kind of manufacturing approach 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 concentrating component of the long-term use out of doors of needs.Often increase considerably the cost and reduction generating efficiency of solar concentrating photovoltaic power generation.

Summary of the invention

Based on this; The purpose of the utility model provides a kind of Salar light-gathering structure of optical thin film material; This concentration structure can promote that the interior concentrating component structure of solar high power condense photovoltaic electrification module is anti-aging, outdoor weathe resistance etc., helps reducing the solar high power condense photovoltaic electrification cost, increases tenure of use.

Another purpose of the utility model is to provide a kind of Salar light-gathering structure of optical thin film material, and this concentration structure is made simple, and is with low cost, has high-weatherability, can anti-soil and hail etc.

For achieving the above object, the utility model is to realize like this.

A kind of Salar light-gathering structure of optical thin film material is characterized in that this concentration structure includes Fresnel Lenses and tempered glass, and Fresnel Lenses adheres to and is fixed on the tempered glass, forms concentration structure with tempered glass.

Said Fresnel Lenses is that the silica gel material makes, and the form fix through the silica gel injection moulding forms an optical thin film material Fresnel Lenses structure on the tempered glass basal surface, and this lens arrangement and tempered glass basal surface form a plurality of first incidence surface lens; And second optical surface, it is located at this tempered glass below; By this, this optical film vertically penetrates the incident ray of different angles.

Said optical thin film material Fresnel Lenses structure includes plurality of films collector lens structure, and each film collector lens structure system is ring texture.

Said Fresnel Lenses is the silica gel of high printing opacity.

The version that the utility model adopts silica gel directly to combine with tempered glass; Broken through the original structural design of Fresnel Lenses; Tempered glass can effectively be protected concentrating component; Make that the concentrating component structure is anti-aging, outdoor weathe resistance good, help reducing the solar high power condense photovoltaic electrification cost, increase tenure of use.

And the utility model is realized simple, with low cost, is convenient to be applied in the various places of solar concentrating photovoltaic power generation.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done into description.

The manufacturing process of Salar light-gathering structure is as shown in Figure 1 in the solar high power condense photovoltaic electrification module of the utility model; One tempered glass 4 is as the main body horizontal positioned of support and concentration structure; Mould 3 that preferably can cover the tempered glass outside surface of the tight pressing in the top of tempered glass 4 has a cavity in the mould 3, cavity body of mould and tempered glass 4 types form a confined space; Make liquid-state silicon gel 1 moulding in this space, accomplish the formation of Fresnel Lenses structure.

The upper surface of mould 3 also has a perforate, and silica gel filling tube 2 is inserted in this perforate, so that the cavity in the mould is poured into liquid-state silicon gel 1.Well heater 6 is set below the

tempered glass

4, and 5 pairs of tempered glass 4 of hot gas heat, and accomplish the curing of liquid-state silicon gel 1.Liquid-state silicon gel 1 is elite optical grade silica gel, deposits in the filling tube 2, and filling tube 2 materials are the Stainless Steel manufacturing; Vertical fixing is in the surface of Fresnel Lenses mould, and the structural plane of Fresnel Lenses structure mold 3 cavitys is to adopt ultraprecise to process; This surfaceness must be below 60um, and the surface presents mirror status, is beneficial to liquid-state silicon gel 1 and flows smooth and easy; The Fresnel Lenses structure adopts a bleed type well heater 6 in the another side of tempered glass 4, treat that liquid-state silicon gel 1 is accomplished filling in the structure space of Fresnel Lenses structure mold 3 and tempered glass 4 after; Well heater 6 starts; Hot gas 5 begins tempered glass 4 heating, after liquid-state silicon gel 1 solidifies, promptly accomplishes and makes.

Shown in Figure 2, sunshine 8 carries out optically focused through Fresnel Lenses 7 again through tempered glass 4, and the light of process Fresnel Lenses 7 back optically focused can be changed on the receiver 9 at sun power by optically focused shown in 10.

The Salar light-gathering structure that completes, as shown in Figure 3, a tempered glass 4 has the Fresnel Lenses 7 that silica gel forms as substrate on the tempered glass 4.Common a plurality of tempered glass constituent components all has Fresnel Lenses 7 on each tempered glass assembly.Tempered glass 4 has one and penetrates the plane of incidence and an exiting surface; And one be located at this tempered glass assembly surface Fresnel Lenses; It has an incidence surface and an exiting surface; This first 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 light-ray condensing in a precalculated position.

In a word, the above is merely the preferred embodiment of the utility model, is not the scope that is used for limiting the utility model embodiment.Be that all equalizations of being done according to the utility model claim change and modification, all in the claim of the utility model.
