Made in the form of a suitably insulated sealed box 1 with a translucent face 2, the collector according to the invention comprises a first bank of parallel tubes 9 connected to two collectors 10, 11 for inlet and outlet of a first gaseous fluid and a second bank of parallel tubes 4 of smaller diameter arranged in front of the previous bank but staggered, which are connected to two collectors 5, 6 for inlet and outlet of a second liquid fluid. To ensure thermal conduction between the tubular banks, it has been envisaged according to the invention to couple them by means of metal U-shaped spacers 15, the wings of which are arranged perpendicularly to the longitudinal axes of the tubes 4, 9 which pass through them, these distance pieces 15 also serving as support chassis for said tubes and allowing their expansion. <IMAGE>
