ABSTRACT:
A heat exchanger having a plurality of flat and elongated tube passes operatively interconnected therein with inlet and outlet openings adjacent to one another so that refrigerant flowing therethrough can transfer the heat energy from a cross flow of air streaming between the tube passes. The tube passes have a divider rib offset so that the volume on the outlet or increased quantity side of each pass is greater than the volume on the inlet or low quantity vapor side. With a large volume available for vapor expansion, pressure drop is minimized and heat transfer performance is maximized in the heat exchanger.
