Cuttage type photoelectric photo-thermal mixing assembly

Abstract

The invention discloses a cuttage type photoelectric photo-thermal mixing assembly, which relates to the technical field of solar electric heat comprehensive utilization. The cottage type photoelectric photo-thermal mixing assembly comprises a monomer assembly and a heat conduction square tube, the monomer assembly comprises an aluminum substrate, a first EVA film, a second EVA film and a photoelectric layer, the upper surface of the aluminum substrate is coated with a solar special heat absorption material, the first EVA film is arranged on the upper surface of the aluminum substrate, the second EVA film is arranged on the upper surface of the first EVA film, the photoelectric layer is clamped between the first EVA film and the second EVA film, the photoelectric layer comprises a plurality of polycrystalline black silicon PREC battery pieces which are distributed along the length interval direction of the aluminum substrate and are connected in series, a bending part is arranged at the side part of the aluminum substrate, the side faces of the heat conduction square tubes make contact with the side faces of the bending parts, and the heat conduction square tubes are filled with liquid heat exchange media. Photoelectricity and photo-thermal are utilized at the same time, and the assembly has the advantages of being large in heat conduction area, large in heat absorption area, capable of running in a full-wave band and high in photo-thermal efficiency and photoelectric efficiency.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of solar energy, electricity and heat, in particular to a cutting-type photoelectric-light-heat hybrid component. Background technique [0002] There are two kinds of existing solar electric heating comprehensive utilization products, one is to graft heat pipes on the basis of photovoltaic modules to realize the comprehensive utilization of electric heating of components; the other is to glue photovoltaic cells on the basis of traditional flat collectors The comprehensive utilization of heat and electricity is realized in the heat absorbing layer. It is impossible for these two types of products to achieve the maximum efficiency utilization of electricity and heat, and they can only choose one of the two. Either increase the power generation, resulting in a decrease in heat utilization; or increase the heat utilization, and the efficiency of power generation will be greatly reduc...

Problems solved by technology

It is impossible for these two types of products to achieve the maximum efficiency utilization of electricity and heat, and they can only choose one of the two. Either increase the power generation, which will lead to a decrease in heat utilization; or increase the heat utilization, and the efficiency of power generation will be greatly reduced.

In addition, existing products can only operate at about 30°C, and the overall electric heating performance is very poor
