Combination concentration module of plane reflecting mirror

Abstract

The invention provides a plane mirror combination condensation module, comprising a type plane substrate and a plurality of plane mirrors mounted on the substrate, wherein each plane mirror is provided with an inclination direction and an angle relatively to the type plane substrate. When assembles the plane mirror combination condensation module and a solar light receiver into a condensation generator, each plane mirror of the plane mirror combination condensation module can condense the incident solar light to the outer surface of the solar light receiver, and the solar light condensed at the outer surface of the solar light receiver is in the form basically consistent to the outer surfaced of the solar light receiver. The plane mirror combination condensation module improves condensation powers, has uniform light intensity distribution and has low demand on the accuracy of trackers. In the assembly of a plane mirror combination condensation generator, the overall design of the plane mirror combination condensation generator can be simple and modularized, having simple and fast installment.

Description

technical field [0001] The invention relates to a solar power generation device, in particular to a plane reflection mirror combined light concentrating module used for making a concentrator. Background technique [0002] Concentrating solar photovoltaic power generation can greatly reduce the cost of photovoltaic power generation. With the continuous improvement of the efficiency of new high-efficiency concentrating cells, concentrating power generation systems will become more and more important in the field of solar photovoltaic power generation. There are many forms of concentrating optical systems. At present, the main application is the parabolic reflective point focusing system. The advantages of this unit are: simple structure, convenient maintenance; easy to upgrade (you can replace the battery with higher efficiency); Variable (multiple combinations can be realized by replacing the flat mirror unit); low cost (low mirror cost, high light-gathering multiple, and re...

But there are also the following disadvantages: First, when a long focal length reflector is used, the light intensity is relatively uniform, but it requires high tracking accuracy, and the length of the focal length is limited by the divergence angle of sunlight (+ / -0.26 degrees); second, When a short focal length reflector is used, the light intensity is severely uneven, but the requirements for tracking accuracy are low. At this time, a more complex secondary optical system is needed to improve the uniformity of light intensity, but its effect is limited
