A heat exchange rib through which a gaseous medium flows to be in heat exchange with another medium. The rib is a strip adapted to receive flow of the gaseous medium along the surfaces thereof, wherein the strip has a first thickness and an edge portion of the strip has a second thickness greater than the first thickness. The edge portion extends in the flow direction of the gaseous medium a width sufficient to increase the average temperature difference between the media. |
