Abstract

The invention discloses a photovoltaic panel with a dual circulation cooling function. The photovoltaic panel comprises a mounting base and a plurality of solar cell pieces, and strip-shaped water collecting grooves are vertically formed in the mounting base oppositely; a liquid cooling unit and a gas cooling unit are arranged in the mounting base; the solar cell pieces, the liquid cooling unit and the gas cooling unit are sequentially connected from top to bottom, and the two strip-shaped water collecting grooves are communicated with the liquid cooling unit separately; the flow direction ofa medium in the liquid cooling unit and the flowing direction of a medium in the gas cooling unit are perpendicular to each other, and a turnover assembly is arranged below the mounting base. Comparedwith the prior art, the photovoltaic panel is compact in structure, rainwater circulation cooling and the cool air circulation cooling are efficiently combined, the temperature of a solar cell backboard is effectively reduced, and the cooling efficiency is integrally improved, so that the power generation efficiency of a solar cell panel is improved, and the service life of the solar cell panel is prolonged; the resistance of series connection cells of the solar cell pieces is low, the photoelectric conversion efficiency is high, the surface is flat and smooth, the adhesive force is good, thewarping curvature is low, and application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic panel with double circulation heat dissipation. Background technique [0002] With the increasingly prominent problems of resource shortage and environmental pollution, solar energy, as a clean and renewable energy, has attracted more and more attention from the world. Therefore, the application of solar photovoltaic power generation is becoming more and more extensive. The key component of solar photovoltaic power generation technology is solar cells. In recent years, crystalline silicon solar cells have developed rapidly as the main solar photovoltaic power generation unit. Photovoltaic power generation units have developed rapidly. Among them, the electronic aluminum paste for silicon solar cells is the main product in the solar electronic paste, usually also called solar cell anode paste, which is used for the formation of the back surface field of the sola...
