Abstract
A light receiving plate floating on the surface of tin, i.e., a low-melting-point heating medium and receiving solar beams is made of solid carbon material entirely coated with a silicon carbide film. Due to the silicon carbide film, the surface of the light receiving plate is black to realize a high absorption ratio of the solar beams. In addition, the light receiving plate is made of the silicon carbide film at least at the surface thereof, to demonstrate excellent heat resistance.
Claims6
A solar heat exchanger having a structure including a top-open, heat-resistant container holding a low-melting-point heating medium and a light receiving plate being supported on and in contact with the surface of the low-melting-point heating medium, wherein
- the light receiving plate is made of solid silicon carbide, or solid carbon material being entirely coated with a silicon carbide film.
