The assembly comprises a plurality of tubular heat-exchanger elements (3) arranged substantially in a circle, there being no intermediate walls extending parallel to the longitudinal axis of the tubes between adjacent heat-exchanger elements. Each heat-exchanger element (3), viewed in section perpendicular to the longitudinal axis of the tubes (4), has at least one intermediate wall (6). In order to reduce the need for thick reinforcement between the heat- exchanger elements, the elements, viewed in section perpendicular to the longitudinal axis of the tubes, are formed as regular hexagons or polygons having more than six sides, and each heat-exchanger element (3) has a central space (5) containing none of the said tubes (4) and extending over the whole depth of the heat-exchanger element and being provided with supply and discharge pipes (7) for heat-exchange fluid. <IMAGE> |
