Uniform flow field solar air heating system with high collection effect

The invention discloses a uniform flow field solar air heating system with a high collection effect. The uniform flow field solar air heating system comprises an aluminum alloy shell body. A heat insulation board is pasted to the inner surface of the aluminum alloy shell body. A heat absorbing plate core, branch flow pipes and a heat collecting pipe are installed in the aluminum alloy shell body, and an air cavity is formed between the heat absorbing plate core and the branch flow pipes. According to the uniform flow field solar air heating system with the high collection effect, the branch flow pipes, a flow gathering pipe and an air pump are used in a matched mode, and heat is continuously absorbed through the heat collecting pipe, so that air in the flow gathering pipe and the branch flow pipes are heated up to become hot air. In addition, the air pump is started under the action of a controller to output the high-temperature hot air to air-using equipment, so that the pressure in the flow gathering pipe and the branch flow pipes is lowered. Cold air enters the system continuously from an inlet of the flow gathering pipe, so that the air is supplemented automatically, and continuous generation of the hot air is ensured. In addition, the air is adopted as a medium of a heat collector, so that the defects that freezing and scaling are liable to occur to a traditional heat collecting pipe for which water serves as a medium are overcome, and the corrosion resistance is improved.
