FIELD: solar-energy technology. ^ SUBSTANCE: solar module with solar energy concentrator can be used for electricity and heat production. Module has mirror reflectors and radiation receiver with two-sided surface. Receiver is mounted in midsection plane between axis of reflector and one its edge. Concentrator is made from n (n=1, 2, 3,) axially symmetric ring-shaped toroid reflectors having common axis of symmetry and common axis of midsection. Cross-section radiuses R of all reflectors equal to distance to center of cross-section from axis of symmetry; they relate as R=2R-1=2rr, where rr is radius of receiver. Any ring-shaped toroid reflected is turned to meet the previous one. All reflector have common axially symmetric receiver with two-sided working surface; diameter of receiver equal to half diameter of n-th reflector. According to the second version, module with concentrator has mirror reflectors and radiation receiver, mounted in diametrical plane between axis of reflector and one its edge. Concentrator is made from two toroid reflectors; midsection planes of reflectors are brought into coincidence. Distance of center of cross-section of big toroid reflector from axis of symmetry is approximately equal to radius of cross-section of big toroid reflector and it twice exceeds radius of cross-section of smaller toroid mirror reflector and distance of center of cross-section of toroid reflector from axis of symmetry. Big and smaller ring-shaped toroid reflectors are turned to meet each other. Radiation receiver had two-sided working surface and it s mounted along axis of symmetry in plane of midsection of smaller toroid reflector. Radiation receiver has diameter to be equal to half diameter of smaller toroid reflector. ^ EFFECT: improved radiation concentration at radiation receiver; bigger angular aperture. ^ 8 cl, 7 dwg |
