Abstract
A low-temperature solar thermal power generation device comprises a heat absorber, a compressor, an expansion engine, a power generator and a pipeline connected therewith. A closed system is filled with a working medium; the heat absorber adopts a high-efficiency heat tube heat exchanger and can be used for absorbing solar heat energy from low-temperature ambient fluids, such as air and water; a low-pressure gaseous working medium absorbing the heat is compressed into a high-temperature and high-pressure gaseous working medium which enters the expansion engine for doing work to drive the generator to generate power; a low-temperature and low-pressure gaseous working medium at an outlet of the expansion engine flows to an inlet of the compressor again through the heat absorber; and the pressure of the outlet of the engine is determined by the pressure of an inlet of the compressor. The low-temperature solar thermal power generation device can be also arranged on a vehicle, a ship and other mechanical devices to serve as a direct power device or a charging device. The low-temperature solar thermal power generation device has the advantages of no heat pump system or condenser, high heat efficiency, extremely-simple structure, low investment and low cost.
