Abstract
A multiple bank, flattened tube, finned heat exchanger includes a first tube bank including a plurality of flattened heat exchange tube segments extending longitudinally and arrayed in spaced parallel relationship between a first manifold and a second manifold and a second tube bank including a plurality of flattened tube segments extending longitudinally and arrayed in spaced parallel relationship between a first manifold and a second manifold, the second tube bank disposed in spaced relationship with and behind the first tube bank. A folded fin is disposed between each set of adjacent heat exchange tube segments of the first and second tube banks. Each folded fin extends between a respective set of adjacent heat exchange tube segments of both the first tube bank and the second tube bank, spanning the spacing gap between the tube banks. A plurality of fin notches protrude outwardly from each folded fin into the spacing gap.
