摘要

The device (1) has a primary radiator (13) with a bundle of coolant circulation tubes (7), and a secondary radiator (21) with a bundle of tubular heating units (15). Each radiator has distinct heat exchange inserts (9) inserted in the bundles of the tubes (7) and the units (15), respectively. The radiators have, in common, gusset plates (11) disposed at the ends of the bundles of the tubes (7) and the units (15). The radiators are assembled as an indivisible module by a pooling of the inserts and the gusset plates.
