Automobile heat exchanger fin module comprise plane metal plate divided into two parts by long slots between which bands of material forming bridges between fin parts extend

摘要

The fin module is constituted from a plane metal plate divided into two parts (18,20) to be passed through by respective tube bundles. The fin parts are separated by long slots (22) between which bands of material forming bridges (24) between the fin parts extend. The bridges comprise a plastic deformation constituting a reinforcement part which extends beyond the plane of the fin.
