A flexible composite textile-based solar collector

Abstract

The invention provides a flexible composite textile-based solar thermal collector which comprises a transparent thermal insulating layer, a fluorescence modified spacer fabric layer, a selective heat absorption layer, a channel film layer and a heat preservation layer. The transparent thermal insulating layer can allow sunlight to pass through; the fluorescence modified spacer fabric layer uses space fabric as a substrate and uses fluorescent powder for modification; the selective heat absorption layer contains selective absorption materials and is formed by coating solar heat absorption coatings; the channel film layer is formed by combining two film layers in a discontinuous linear gluing mode to form a channel and arranging heat transfer media in the channel; the heat preservation layer is used for heat preservation and heat insulating; and all the layers are sequentially laminated through a thermosetting adhesive and packaged overall. Sunlight passes through the transparent thermal insulating layer and is absorbed by the fluorescence modified spacer fabric layer, so that waveband light with higher thermal performance is emitted; the waveband light is absorbed by the selective heat absorption layer and then is converted into heat energy; and the heat energy is led out by the heat transfer media in the channel film layer to be used. The flexible composite textile-based solar thermal collector is prepared by flexible materials, and is simple in structure, low in cost, flexible, light, thorough in energy transmission, good in heat collecting effect, diversified in color and convenient to mount and maintain.

Description

technical field [0001] The invention relates to the technical field of solar energy equipment, in particular to a novel flexible composite textile-based solar heat collector. Background technique [0002] A solar collector is a device that absorbs solar radiation and converts it into heat. At present, there are many types of solar collectors, and for different types of collectors, there are great differences in their ability to convert solar energy. Solar heat collectors on the market can generally be divided into several types such as flat plate heat collectors, concentrating heat collectors, and flat reflectors. In the prior art, most solar collectors use rigid and heavy materials, which have many problems in terms of conversion rate and flexibility. Moreover, the price of the metal type collector is high, and the process is relatively complicated. In particular, there are many problems in matching with buildings. [0003] With the development of modern material scienc...
