Abstract
A solar energy collector comprising a collector core located within a longitudinal parabolic reflector and formed of a series of spaced tubes exposed to the direct rays of the sun and to rays reflected by the reflector and arranged in a cylindrical array extending longitudinally to form a fluid path between two end annular manifolds connected at opposite ends of a storage tank located within the array.
Claims10
A solar collector, comprising:
- a longitudinal parabolic reflector;
- a collector core assembly within said reflector and formed of a series of spaced tubes exposed to the direct rays of the sun and to rays reflected by said reflector;
- said tubes being arranged in a cylindrical array and forming a fluid path between annular inlet and outlet manifolds;
- a storage tank located within said array;
- and
- means for connecting said manifolds to opposite ends of said tank whereby said fluid is heated as it passes in said tubes from said inlet manifold to said outlet manifold to said tank.

A solar collector comprising in combination, a longitudinal parabolic reflector;
- a collector core assembly within said reflector and formed of a series of spaced tubes exposed to the direct rays of the sun and to rays reflected by said reflector;
- said tubes being arranged in a cylindrical array between annular inlet and outlet manifolds;
- a storage tank located within said array;
- means for connecting said manifolds to opposite ends of said tank;
- said tank receiving fluid circulating in said tubes;
- and
- electrical heating means immersed in said tank for boosting the temperature of fluid therein during periods of inadequate sunlight.

A solar collector comprising, in combination, a longitudinal parabolic reflector;
- a collector core assembly within said reflector and formed of a series of spaced tubes exposed to the direct rays of the sun and to rays reflected by said reflector;
- said tubes being arranged in a cylindrical array between annular inlet and outlet manifolds;
- a storage tank located within said array;
- means for connecting said manifolds to opposite ends of said tank;
- said tank receiving fluid circulating in said tubes;
- and
- a pump connected between said tank and said collector core to circulate fluid from said tank through said tubes at a rate of circulation greater than that due to the thermosyphon effect in said tank.
