Abstract
A tube assembly for use in a heat exchanger is made by arranging a first corrugated fin structure between one broad, flat side of a tube and a side sheet, and arranging a second corrugated fin between another broad and flat side of a tube and another side sheet. Compressive forces are applied to the opposite faces of the side sheets to place crests and troughs of the corrugated fin structures into contact with the side sheets and the broad, flat sides, and the assembly is brazed.
