Abstract

The invention relates to a heat-pipe type panel solar air collector and a heating method thereof. The collector comprises a solar panel heat collection and heat transmission section and an air ventilation heat exchange section. The solar panel heat collection and heat transmission section comprises tempered glass, an efficient heat absorption coating, a heat insulation air layer and a panel heat pipe evaporation section. The back of the efficient heat absorption coating and the obverse side of the panel heat pipe evaporation section are combined organically. The tempered glass covers the outer surface of the panel heat pipe evaporation section organically combined with the efficient heat absorption coating. The heat insulation air layer is arranged between the efficient heat absorption coating and the tempered glass, and the distance from the front of the efficient heat absorption coating to the inner surface of the tempered glass ranges from 20 mm to 50 mm. The air ventilation heat exchange section comprises an air duct, a fan and a panel heat pipe condensation section. The panel heat pipe condensation section is arranged in the air duct, and the fan is arranged on one side of the air duct. The collector has the advantages of being high in heat exchange efficiency, high in reliability, simple in structure, convenient to mount, free of maintenance and long in service life.

Description

technical field [0001] The invention relates to the technical field of solar heating, in particular to a novel heat pipe type flat solar air heat collector and a heating method thereof. Background technique [0002] In order to realize the efficient use of solar energy, compared with solar collectors using water as the working medium, air has its unique advantages, such as relatively low investment, can prevent freezing in winter, do not need to worry too much about leakage problems, and start up quickly etc., so that the solar air collector can be used simply and effectively for heating in winter, optimizing indoor airflow organization, etc., and has become a new direction of solar heating. In the non-heating season, in order to avoid energy waste, it can also be used for drying of industrial and agricultural by-products. The plate solar air collector is a device that directly uses air for heat collection. Its structure is simple, and it is very suitable for building heat...

Problems solved by technology

[0004] The present invention aims at the problems of low heat transfer efficiency and poor reliability caused by the direct heat exchange between the air and the heat-absorbing film of the existing plate-type solar air heat collector, and provides a new type of heat pipe-type flat-plate solar air heat collector, which is equipped with a solar plate heat collector With the heat transfer section and the air ventilation heat exchange section, the flat heat pipe with the micro heat pipe array is closely organically combined with the heat-absorbing coating. The continuous condensation and evaporation phase change of the working medium in the flat heat pipe finally exchanges heat with the air in the air duct. The heat pipe can realize large-area heat absorption and high-efficiency heat release in the condensation section, and the collector realizes the separation of solar heat collection, heat transportation and air heat exchange, which is different from traditional solar air collectors that collect solar energy The disadvantage that the heat surface and the air ventilation heat exchange surface can only be integrated, the invention can greatly improve the absorption efficiency of solar energy and heat transfer efficiency, while enhancing the heat collection effect, the heat collector can greatly reduce the air flow resistance
