solar engineering. SUBSTANCE: concentrator has two concentration stages of which first stage 1 has two tiers in the form of multilayer truncated cones with acute aperture angle; upper and lower tiers are covered with reflecting layer on inner and outer surfaces, respectively. Second stage is optically coupled with first one and has two spherical concave and convex mirrors 2 and 3, respectively, with equal curvature radii. Small mirror 3 is installed with its convex part in front of large mirror focus. Large mirror 2 has central hole for passing spherical rays. Concentrator of such design has large Sun-oriented area affording high degree of concentration and relative parallelism of outgoing rays. EFFECT: enlarged functional capabilities. 1 dwg |
