Abstract

PURPOSE: To achieve the improvement in the heat collecting efficiency of the heat collector by installing a light-receiving pipe to the circular light-collecting means which is so arranged that its focal length becomes shortest in the central part of the light-collecting means and becomes subsequently longer as it goes toward the outside circumference, perpendicularly to the light-collecting means.
CONSTITUTION: A circular Fresnel lens 1 comprises linearizing the curved faces of spherical lens 6 between arbitrary widths l1, l2... like straight lines x0x1, x1 x2..., setting their inclination angles α1', α2'... to α1'=α1, α2'=Aα2, α3'=Bα3... with respect to the inclination angles α1, α2... where A, B... ar constants and A<1, B<A... and providing the difference in level corresponding to the heights h1', h2'... of the respective segments. Hence, the circular Fresnel lens 1 becomes longer in focal length subsequently as it goes toward the lens outside diameter and a light- receiving pipe 3 is disposed in its focal position, between the focal lengths of the innermost circumferential part and the outermost circumferential part of lens 1. Since the heat medum 5 flowing in the light-receiving pipe 3 is heated evenly over the entire circumference of the light-receiving pipe 3 in this way, the heat-collecting efficiency becomes higher.
