Solar energy focusing means comprising modular elements

摘要

The invention concerns a cylindro-parabolic reflector for focusing solar rays on the focal axis of the cylinder. The reflector comprises modular elements which are assembled by means of tubes which are interengaged strictly in alignment with each other. The complementary male and female ends of the tubes have been formed by the tubes previously having been forcibly engaged into each other. This makes it possible to provide reflectors of substantially perfect parabolic shape, in spite of their substantial length. The invention will be used primarily in the construction of solar steam generating stations.
