摘要

Flap for the conduction of a fluid to be cooled, and heat exchanger of stacked plates equipped with such fins. The flap comprises a plurality of ducts (4), through which the fluid to be cooled circulates from an entrance zone (3a) to an exit zone (3c) disposed respectively on opposite ends of the flap (3). It is characterized by the fact that the passage surface of the ducts (4) decreases according to the direction of advance of the flow of fluid to be cooled, keeping the total surface of passage along the fin (3) substantially constant, so that that the thermal transfer of said fin is optimized. Preferably, the fin comprises at least two zones (3a to 3c) of ducts (4) arranged adjacently according to the direction of advance of the flow of fluid to be cooled, so that the width of the ducts (4) of the respective zones (3a) a 3c) decreases gradually, while the number of ducts (4) increases.
