A heat exchanger in which heat is transferred from one fluid to another by conduction through stationary annular cells (108a) to (108d) with corrugated plates (112a) (112b) which are flattened at their axially outer ends (114a) (114b). The cells (108a) to (108d) have differing diameters with adjacent cells closely fitting inside one another to form an annular matrix between an outer (106) and inner (104) casing. Compressed air flowing to a gas turbine engine enters through inlet openings (110a), passes through a first fluid tight compartment and leaves through outlet openings (110b). While passing through the heat exchanger, the compressed air receives heat from the engine exhaust gas, which passes from inlet (117), through a second fluid tight compartment to outlet (118). |
