Abstract

The invention relates to a pantile condensing apparatus which is formed by vertically connecting a pantile condensing lens and a condensing groove, wherein the pantile condensing lens comprises an incident plane and a plurality of light emitting planes; light rays in any direction radiate on the same wavy plane of the incident plane; the light emitting planes comprise a plurality of symmetrically designed cylindrical linear Fresnel lenses with equal width; one arris edge of a small prism is vertical to the wavy plane; the other arris edge forms an arris of smaller than 60 degrees with the wavy plane; the small prism for the light rays in different incident heights deflects to a main optic axis with a minimum deflection angle; most of emitting light rays directly fall on a fixing plane of a lower mouth of the condensing groove; a part of emitting light rays are reflected to the fixing plane of the lower mouth of the condensing groove through a reflecting wall of the condensing groove to form a uniform solar focusing band; and low-power light condensation can be still realized without a solar tracking system. The generating cost of solar energy is reduced, and the pantile condensing apparatus is simple in structure, high in photoelectric converting ratio and easy to combine with construction.

Description

The corrugated tile concentrator

Affiliated technical field

The present invention relates to field of solar thermal power generation, specifically is a kind of corrugated tile concentrator.

Background technology

Solar photovoltaic technology does not provide bright prospects for solving energy problem, but has the cost of electricity-generating height, the problem that photoelectric conversion efficiency is not high.Therefore, reduce cost and raise the efficiency the key that becomes the solar power generation large-scale application, Salar light-gathering is the effective way that reduces the solar energy power generating cost.Sunlight optically focused generally adopts modes such as Fresnel lens, flute profile reflection, parabolic reflector, just can reach spotlight effect but need to install the sun light tracking device.Adopt the sun light tracking device, the cost height, poor reliability can't combine with architecture-integral, is not easy to install.Cancellation sun light tracking device is the technical problem that present field of solar thermal power generation presses for solution.

In order to cancel the sun light tracking device, the mode that adopts ball to focus on is arranged at present, as number of patent application is 20610076928.3 disclosed a kind of " sun light collectors ", patent No. ZL200620005067.5 disclosed a kind of " universal condenser ", patent No. ZL200820185105.9 disclosed a kind of " omnirange sunlight beam condensing unit ".These optically focused modes can be assembled sunlight, focus on than high, but because volume, weight are bigger, be inconvenient to install, in field of solar thermal power generation practicality popularization on a large scale.

In sum, existing optically focused mode can both be solar light focusing in a bit, and focus point moves along with moving of sunlight, adopts generally that cost is higher, the sun light tracking device of unstable properties, installation and maintenance inconvenience, difficultly combines with building.

Summary of the invention

The objective of the invention is that sunray focuses on a bit in the prior art in order to overcome, focal point moves with sunlight, need to install the shortcoming of sun light tracking device, a kind of corrugated tile sunlight collector is provided, adopt the wavy surface light harvesting, the lens light gathering of symmetric design, condenser groove reflecting condensation be the optically focused mode of light all, sunlight is gathered on the fixing banded plane all the time, saves the sun light tracking device.

To achieve these goals, the technical solution used in the present invention is: the corrugated tile concentrator comprises corrugated tile collector lens and condenser groove, technical characterstic is that described corrugated tile collector lens comprises that having any direction light is incident on the incidence surface of same wavy surface and the some exiting surfaces that wait the linear Fresnel lens of width cylinder to form of several symmetric designs, one corner angle limit of little prism is perpendicular to wavy surface, another corner angle limit and wavy surface form corner angle, the little prism of different incident eminences is partial to minimum deviation angle primary optical axis light, most of emergent ray directly drops on the condenser groove end opening fixed pan, the part emergent ray reflexes on the condenser groove end opening fixed pan through the reflection wall of condenser groove, forms the burnt band of uniform sunlight.

Described corrugated tile collector lens is the linear Fresnel lenses of width cylinder such as symmetric design that are equal to or less than semicanal shape, and mouth of pipe direction adopts the one dimension east-west direction to place.

The width of described each little prism of corrugated tile collector lens is 0.1-6mm.

Each little prism corner angle of described corrugated tile collector lens are less than 60 °.

The upper and lower mouth of described condenser groove is quadrangle, and suitable for reading big young down, the angle of side and baseplane is 60 °, and the condenser groove end opening connects solar battery sheet or solar module.

Embodiment

With embodiment the present invention is elaborated in conjunction with the accompanying drawings.

Fig. 1,2, in 3, a kind of corrugated tile concentrator, mainly contain corrugated tile collector lens 1 and reflective mirror condenser groove 3 compositions, corrugated tile collector lens 1 is a semicanal or less than semicanal shape, corrugated tile collector lens 1 comprises that having any direction light is incident on the incidence surface of same wavy surface and the some exiting surfaces that wait the linear Fresnel lens 2 of width cylinder to form of several symmetric designs, one corner angle limit of little prism is perpendicular to wavy surface, another corner angle limit and wavy surface form less than 60 ° of corner angle, the little prism of different incident eminences is partial to minimum deviation angle primary optical axis light, most of emergent ray directly drops on the condenser groove end opening fixed pan 4, the part emergent ray reflexes on the condenser groove end opening fixed pan 4 through the reflection wall of condenser groove, forms the burnt band of uniform sunlight.Condenser groove adopts glass silvering minute surface or aluminium reflective membrane, the upper and lower mouth of condenser groove is quadrangle, up big and down small, the angle of side and baseplane is 60 °, and the condenser groove end opening connects solar battery sheet or solar module and light concentrating times and adjusts controlled with distance.
