COMPOUND REFLECTOR OF FOUR CONCAVE CYLINDRICAL REFLECTORS CONCENTRATING SUNLIGHT ON ABSORBER™S ISOSCELES TRIANGLE SECTIONED BO NDARY�.

摘要

ABSTRACT OF THE INVENTION The device named as compound reflector of four concave cylindrical reflectors concentrating sunlight on absorber™s isosceles triangle sectioned boundary� is a solar energy collection device, and relates to Physical Sciences. The device comprises of following components. A compound concave cylindrical sunlight reflector consisting of a pair of quadrant sectioned concave cylindrical sunlight reflectors, and another pair of semi quadrant sectioned concave cylindrical sunlight reflectors� provided to reflect most of incident sunlight towards vertical axis of said compound concave cylindrical sunlight reflector. A ˜means for solar energy absorption™ provided along vertical axis of said compound reflector to intercept and absorb energy of sunlight reflected by said compound reflector towards isosceles triangle sectioned boundary surrounding said absorber™s longitudinal axis. Said absorber is provided with two equal length sides subtending an internal angle ˜either equal to or more than™ 90 degrees at its bottom end apex. A big framed structure provided to hold and support said ˜two pairs of concave cylindrical sunlight reflectors™ and said detachable ˜means for solar energy absorption™ in predefined relative positions�. Detachable plane mirror provided along either side outer vertical faces of compound concave cylindrical sunlight reflector, for reflecting of outward moving sunlight towards said absorber. Said compound concave cylindrical sunlight reflector is ˜a stationary sunlight concentrator, and capable of reflecting concentrated sunlight on said ˜means for solar thermal energy absorption located at its vertical axis™ throughout day even without any adjustment. Proper orientation of said reflector� either once in a day or once in a week such that it is cable of intercepting more sunlight by turning its towards the Sun, and supporting it on suitable inclined surface to hold its top surface as inclined to horizontal at an angle equal to latitude of the location� leads to extraction of maximum possible output from said equipment.
