A heat exchanger includes a cooling air conduit having multiple baffles, a hot air conduit having multiple passes through the cooling air conduit and forming multiple intersections with the baffles, and multiple perforations extending through the baffles. A cooling air flow passes through the baffles, rather than strictly between the baffles, and improves heat-transfer characteristics of the heat exchanger.
