A heat exchanger is described which is adapted for use with a regenerative type gas turbine engine. The heat exchanger comprises a stack of annular disc plates which are joined in bellows fashion. Inlet and exit plenums extend longitudinally of the stack. The plates define alternate flow paths respectively for radial flow of the hot gas discharge outwardly from the center of the stack and for cross flow of pressurized air from the inlet to exit plenums. Alternate plates are provided with flow path defining corrugations formed both radially, in a general sense, and cross wise, generally concentric of the discs. The remaining plates have generally radially extending, flow paths defining corrugations. The radial corrugations of all plates are curved to be generally concentric of the curved sides of the inlet and exit plenums which are respectively triangular and elliptical in cross section.
