1. Vertical insolator with flux concentration comprising at least two tubular absorbers arranged for the passage of a heat transfer fluid and a flux reflector, characterized in that each tubular absorber (9) with absorbing walls comprises two substantially diametrically opposite, longitudinal angular faces (22, 23; 24, 25), each of which has a substantially V-shaped cross-section with its point directed towards the axis of the absorber (9), whereof the two sides of the V form an angle (12, 13) substantially corresponding to the angle between the summer solstice and the winter solstice at the point of use of the insolator, the tubular absorbers (9), in the use position, being arranged in horizontally superimposed manner with an angular face (22, 23) open in the direction of the sun and its walls respectively directed in the direction of the summer solstice and the winter solstice and in that the flux reflector (26) located behind the tubular absorbers (9) is constituted by a plurality of superimposed reflecting panels having, in cross-section, a zig-zag configuration forming the same number of projecting dihedrons (K1 , K2 , K3 ) as there are absorbers, each projecting dihedron also being pointed towards a corresponding absorber (9), in such a way that the bisecting planes (Z1 , Z2 , Z3 ) of the walls of the projecting dihedron pass through the central axis (O1 , O2 , O3 ) of the corresponding absorber, said bisecting plane (Z1 , Z2 , Z3 ) being symmetrical, with respect to a vertical plane (C), to the bisecting plane (E) of the angular face turned towards the sun. |
