| 摘要 |
The invention pertains to the field of solar heat exchangers, specifically solar receivers or solar absorbers used in solar thermal energy collectors. The solar receiver of the invention comprises a comprises a porous three-dimensional 'graphene foam' thermal conduction core (201) in direct three- dimensional contact with a heat transfer fluid (207) within an evacuated translucent inner tube (203) that is exposed to direct solar radiation. Alternatives without substantial differences exist in the disclosure. The receiver is integrated in a solar thermal energy collection system, such as a parabolic trough concentrated solar power system. |
