STRUTTURA DI ALETTA PER SCAMBIATORE DI CALORE PER APPLICAZIONI AUTOMOTIVE, IN PARTICOLARE PER MACCHINE AGRICOLE E DA CANTIERE

Heat exchanger for a heat exchange between air and a heat exchange medium, comprising - a plurality of heat transfer conduits (2) arranged parallel to each other as flow paths for the heat exchange medium; and - a plurality of fin members (3) configured to provide an air inlet end (3a) for air inflow, an air outlet end (3b) for air outflow, and an air flow path which connects the air inlet end (3a) with the air outlet end (3b) and allows a heat exchange with the plurality of heat transfer conduits. Each fin member comprises a plurality of undulation troughs (19) coplanar with each other and connected together so as to define a water condensate flow path having a flat bottom which extends from the air inlet end (3a) to the air outlet end (3b).
