The device has a ceramic central cover, and a flag shaped elementary exchanger including exchanger tubes that are connected to an inlet manifold (5) and an outlet manifold (6), respectively. The exchanger tubes are superposed for blocking incident radiation. Each tube is in the form of hairpin with a loop (4) at its pinhead and two joined branches (2, 3) that are superposed in a vertical manner, where an end of the tube at the level of the pinhead is free. The tubes are self-supported at their ends connected to the manifolds. |
