Heat exchanger for car has metallic tape stamped to form indentations defining two semi-channels put together to create complete U-shaped channel

摘要

Metallic tape (16) is stamped to form, successively on period (P), first indentation (18), second indentation (20) and separating section (22). Indentations are folded along line (24). Indentations define semi-channels (26, 28) that form complete U-shaped circulation channel when indentations are brought together.
