Abstract
A heat exchanger core (20) has tubes (22) which are stiffer and more resistant to core assembly compression at the elongated tube edges (24). Corrugated cooling fins (46) stacked between the tubes (22) have fin walls (48) that cross the stiffer tube edges (24) and a series of vane like louvers (54, 56) that are regularly spaced along the fin walls (48). The outboard louvers (56) on both sides of each fin wall (48) are strategically shortened, as compared to the longer inboard louvers (54) so that the fin walls (48) will be stiffened less, and less subject to buckling when the core (20) is stacked during assembly.
