Abstract (en)
[origin: EP0971195A2] The invention relates to gas - liquid heat exchanger, comprising at least two heat exchanger elements, each one providing at least one liquid passage channel (3, 4, 5), or liquid side, externally providing a finned pack (7), or gas side, with fins (7) substantially parallel each other, coupled in correspondence of their root with said at least one passage channel (3, 4, 5), said at least two heat exchangers being in hydraulic communication each other with a liquid passage from one element to the other one in a direction opposite with respect to the gas motion direction, and the finned packs (7) of the passage channels (3, 4, 5) of the relevant exchanger elements being penetrable each other, the penetration rate of the finned packs (7) being variable. <IMAGE>
