<p>A refractive concentrating flat plate solar thermal collector belongs to the field of medium and high temperature solar applications. Sunlight (1) is connected by a huge line-focus Fresnel lens (2), so as to improve the energy flux density of the sunlight and generate a high temperature at a focal line; heat is collected efficiently by evacuated solar collector tubes (7, 8, 9), and high-temperature heat energy is exchanged and led out by feeding a heat-conducting medium into a U-shaped metal tube (12), so as to provide a high-temperature heat source for domestic and industrial fields such as heating, air conditioning, textile, printing and dyeing, papermaking, rubber, sea water desalination, and sewage purification. An array of a plurality of the refractive concentrating flat plate solar thermal collectors can form a high-power solar steam boiler, which can be used for power generating of a heat generator set.</p> |
