Abstract
The utility model discloses a light-focusing type photovoltaic cell light-focusing thin film produced through hot-forming technology. The thin film adopts a single-layered film material with a thickness ranging from 0.1mm to 1.5mm, and a maximal width being 2m. The hot-forming Fresnel mirror thin film has a low cost, is convenient for transport and installation, can greatly reduce the cost of the Fresnel mirror, and expands the application range of the conventional material.
Description
Technical field
The utility model belongs to light-focusing type optical thin film material type.Specifically, this material is a kind of film of multifunctional and multipurpose, such as all having a wide range of applications in fields such as light-focusing type photovoltaic generation, infrared passive mobile detection, Projection Display, light opticses.
Background technology
Present stage the Fresnel mirror thickness generally more than 5mm, be commonly called as Fresnel mirror thin plate, its full-size is diameter or length of side 0.5m, the Fresnel mirror of this model is used widely at infrared mobile detection, Projection Display and the light optics neck of having no chance, but for the required concentrating collector of the great light-focusing type photovoltaic generation of demand, the Fresnel mirror of this specification just is not suitable for.The someone develops large-scale Fresnel lens to be used to make solar concentrating collector in the world, and it is in light weight, and price comparison is low, and the branch of point focusing and line focus is arranged, and is generally made by organic glass or other transparent plastic, and also useful glass is made.Someone adopts the point focusing Fresnel lens of combination forming cutter processing diameter 1.5m, but precision is not high, the raising of still needing.Also the someone adopts the UV ultraviolet curing process to make large scale Fresnel mirror thin plate, and all more than 1mm, maximum monolithic size can only accomplish that the length of side or diameter are 1.5m to its thickness.Our company adopts hot press forming technology with Fresnel mirror filming, producing thickness is the single layer structure Fresnel mirror film of 0.1mm to 1.5mm, this hot press forming technology can be made into the Fresnel mirror coiled material shape membraneous material of wide 2m, long hundreds of rice even several kms, greatly reduce the cost of Fresnel mirror, widened the application of Fresnel mirror.
Summary of the invention
The utility model is Fresnel mirror mould molded film to be made of through the single thin film with Fresnel mirror structure that the heating and pressurizing moulding process forms.This form film is generally transparent plastic, it is made by one or more the material among polycarbonate PC, polymethyl methacrylate PMMA, polyvinylchloride, poly terephthalic acid PET, polyamide PA, the polystyrene PS, and concrete condition is decided on environment for use and client's demand.Upper surface of the present utility model is smooth plane, and lower surface is the interface with Fresnel mirror structure formation of optical convergence's effect.This uses novel described Fresnel mirror film is a kind of film of single layer structure, and thickness is generally between 0.5mm to 1.5mm; This film both can be single sheet also can be made into maximum wide cut reach 2 meters, length reach hundreds of rice the web-like film.For the concentrating solar generating, this film has converging ray to prolong the function of effective generating dutation and increase generated energy, and it can significantly reduce the use amount and the cost that reduces the light-focusing type photovoltaic generation of silicon chip simultaneously.
The utility model can be fixed on the support separately and use, and is fixed on the support after also can fitting with transparency glass plate, transparent plastic sheet again and uses.
Fig. 1, Fig. 2 are the structural representation of the utility model section.
Fig. 3, Fig. 4 are that technological process of the present utility model realizes synoptic diagram.
Embodiment
Below in conjunction with embodiment the utility model is further described, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the novel section of this use is the donut with " sawtooth " shape.According to shown in Figure 2, the utility model is to be made of the Fresnel mirror structural membrane that one deck has good optically focused performance and a light high permeability.The utility model upper surface is level and smooth plane, is Fresnel mirror interface below.The utility model adopts hot press forming technology to make, and at first requires to design and produce out the Fresnel mirror mould of respective pitches according to different focal lengths, utilizes this mould can finish through heating and pressurizing, releasing process the moulding smooth film again.Ability uses the new production process flow process referring to Fig. 3, Fig. 4.
The utility model can cut into any plane shape, is fixed on the transparency glass plate by gluing or other modes then, this glass plate is fixed on the support uses again, also can directly this material be fixed on the support and use.
As mentioned above, just can well realize the utility model.
