A heat exchanger including a plurality of heat exchanger plates in a stacked arrangement. At least two counterflow sections are positioned adjacent each other. The counterflow sections comprise an intermediate section of each heat exchanger plate. The heat exchanger plates configured to transfer heat between a first fluid and a second fluid flowing in an opposite directions from the first fluid through a respective heat exchanger plate. At least one tent section is positioned on each end of each counterflow section. The tent sections are configured to angle the flow direction of the first and second fluids in the tent sections relative to the flow direction in the counterflow sections. A wall is positioned between each tent section and each counterflow section configured to provide a load path at opposite ends of the heat exchanger to oppose forces due to pressure on the tent sections.
