Improved metallic fin for heat exchanger, more particularly for automotive vehicles.

摘要

The fin assembly consists of a central section (12) with at least one set (6) of fixed inclined fins (7), separated by gaps (8) to allow a passage for a fluid between them. The fins in the fixed set (6) are divided into at least two groups inclined in opposite directions, and with the fins in each of the groups being inclined at different angles, e.g. at 20 degrees , 24 degrees and 28 degrees . Sets of fins between and outside the inclined groups are made with both flat (11) and inclined (9,10) sections.
