<p>A heat exchanger is composed of a pack of thin metal sheets (100) laid one upon the other and spaced, each comprising two pairs of opposite sides (3, 4) and coupled alternatively to the adjacent sheets in correspondence of the first (3) and of the second (4) pair of opposite sides, of two covering panels (102) for the pack of sheets and of corner ribs (8) providing for the connection of the panels. Each covering panel is soft and partially flexible, and it consists essentially of a layer of non-conductive material (6). <IMAGE></p> |
