A heat exchanger can include a cooling air conduit having at least one baffle, as well as a hot air conduit having at least two passes through the cooling air conduit. The heat exchanger can further include at least one perforation extending into the least one baffle. The perforation can have a passage connecting an inlet to an outlet.

Heat exchanger with non-orthogonal perforations

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.
