Abstract
Bi-directional fin stock, for use in heat exchangers of the fin and tube type, having louvers formed from the planar surface of the fin stock to project progressively farther into the airstream. This enables the fin stock to exchange heat with a broader airstream by translating the airflow substantially, permitting wider fin spacing.
