Solar concentrating photoelectric heat cogeneration module

Abstract

The invention provides a solar condensation power and heat cogeneration module which comprises a base frame, at least two groups of high-reflection semi-disk mirrors, an integrated radiating pipe and high transmittance tempered glass, wherein the base frame is used as a bearing part of the integral module; arc installation positions capable of being used for fixing the high-reflection semi-disk mirrors are arranged on the base frame; the high-reflection semi-disk mirrors are arranged in parallel in the installation positions of the base frame; the integrated radiating pipe is arranged on the base frame; a plurality of concentrator solars for concentrating the sunlight reflected by the high-reflection semi-disk mirrors are symmetrically arranged at both sides of the integrated radiating pipe; and the high transmittance tempered glass is arranged on the base frame and is covered at the top ends of the high-reflection semi-disk mirrors and the integrated radiating pipe is packaged under the glass. Moreover, according to the invention, the aim of high efficiency solar condensation power and heat cogeneration can be fulfilled and the comprehensive solar electric heat utilization efficiency reaches over 70 percent.

Description

technical field [0001] The invention relates to the technical field of solar energy application, in particular to a high-efficiency solar energy concentrating photoelectric heat cogeneration module applied to an electric heating system. Background technique [0002] Global warming caused by greenhouse gas emissions has attracted more and more attention from the international community. Strengthening energy conservation and emission reduction is an important means to deal with global climate change and the challenges of resource shortage and limited environmental capacity. Solar energy, as a renewable energy source, its development and utilization Saving conventional energy, protecting the natural environment, and mitigating climate change are all of great significance. Compared with conventional energy sources, solar energy also has many advantages such as large total energy, long-term durability, universality, and no pollution. .

[0005] However, the light-gathering efficiency of the Fresnel lens is low (about 80% or less). At the same time, the focal length of the Fresnel lens will become longer with the increase of its area, which will increase the thickness of the entire module, thereby increasing the The volume of the whole module is increased, it is more troublesome in the process of packaging, handling or installation, and it will also increase the cost

In addition, the waste heat of gallium arsenide cells in the traditional concentrating power generation module of gallium arsenide has not been utilized, wasting resources; Costly and hard to reduce
