Abstract
A plate fin heat exchanger having a plurality of tubes generally perpendicular to and extending through a stack of humped plate fins. The plate fins have a plurality of holes to receive the tubes. These holes are disposed in rows, and are defined by wrinkle free collars surrounding the holes. A number of trapezoidal stiffening beads both short and long are integral to the plate and are disposed between the rows of holes. The rows of holes coincide with rows of arced humps in the plate fins.
