An air to air counter flow heat exchanger 1 having a cavity wall that defines a heat exchange cavity 2, a plurality of spaced apart plates within the cavity and arranged such that the gaps between them define at least one first air flow path 13 and at least one second air flow path 14. Each air flow path extends from a corresponding air input port 7, 8 to a corresponding air output port 9,10, each first air flow path being in thermal contact with at least one second air flow path. The air input ports and air output ports are arranged such that the first air input and output ports on one side of a dividing plane 18 and the second air input and output ports on the other side of the dividing plane. The cavity wall may include first 4 and second 5 end faces with a sidewall between, with the air input and output ports extending through the side wall 6. The thickness of the air flow paths that extend between end plates (12, figure 4) may vary with position within the heat exchanger.
