Abstract

The invention discloses a concentrating photovoltaic battery air-cooled heat dissipation system which comprises a set of concentrating photovoltaic battery sheets. The concentrating photovoltaic battery sheets are arranged into an inclined concentrating photovoltaic battery array. The concentrating photovoltaic battery array and a Fresnel lens above the concentrating photovoltaic battery array form a component. Heat dissipation rectangular tubes are arranged side by side beneath the concentrating photovoltaic battery array. Air outlets on the upper ends of the heat dissipation rectangular tubes are inserted into the lower part of an air cavity of the same air heating component. The upper part of the air cavity of the air heating component is connected with a chimney. The air heating component and all heat dissipation rectangular tubes are arranged on a mounting bracket. The mounting bracket is fixed on a dual-shaft tracker. According to the invention, energy consumption is avoided; the reliability is high; temperature difference is used for heat dissipation; heat of the condensation photovoltaic battery array is well dissipated; the service life of the concentrating photovoltaic battery array is ensured; and the problem that the heat dissipation intensity of a traditional passive heat dissipation method does not match a heat dissipation demand is solved.

Description

technical field [0001] The invention belongs to the field of concentrating photovoltaic cells, and in particular relates to an air cooling system for concentrating photovoltaic cells. Background technique [0002] Concentrating photovoltaic cells can directly convert concentrated sunlight into electrical energy, and it is a widely used battery. When the sunlight is strong, the light radiation is strong, the power generation is more, and the heat radiation is also large, and the heat radiation will shorten the service life of the concentrated photovoltaic cells. [0003] There are two commonly used cooling methods, namely: active cooling and passive air cooling. Among them, the cooling effect of the active cooling method is good, but it requires energy consumption, and the service life of the concentrating photovoltaic cell is long, generally several decades, while the service life of the active cooling device is short, which leads to poor reliability of the active cooling m...
