Abstract
The present invention is an improved serpentine heat exchanger. Two metal sheets are crimped together, sealed at their abutting edges. The sheets have matching depressions which from a serpentine air passageway. Within the passageway are elongated ribs and column like dimples which serve as obstruction to the air flow, directing fluid flow over under-utilized portions of the passageway and generating turbulent fluid flow near heat transfer surfaces.
