Abstract
A parabolic collector for the concentration of solar radiation has a reflective surface which is approximated to an ideal paraboloid and has a number of individual collectors. According to the invention, individual collectors are provided with a pressure cell with a concentrator formed from a flexible film, whereby, under operating pressure conditions, the concentrator is curved differently in a predetermined manner in a first and in a second direction for approximating the ideal paraboloid, such that the radius of curvature in the first direction is greater than that in the second direction. The production method for such a concentrator consists in the fact that the outline of the individual collectors is designed in the outline of the parabolic collector, the true dimensions of the individual collectors being determined from the intersection of cylinders positioned on the outline with the paraboloid of the parabolic collector.
