2081099 9119153 PCTABS00008 Circular heat exchangers have been used to increase the efficiency of engines by absorbing heat from the exhaust gases and transferring a portion of the exhaust heat to the intake air. The present heat exchanger (10) is built to better resist the internal forces and pressures (68, 70) and to better withstand the thermal stress from the cyclic operation of the engine (12). The plurality of evenly spaced individual tension rings (180) are positioned about the outer portion (28) of the core (22) and the plurality of compressive hoops (184) which are positioned at the inner portion (27) of the core (22) resisting the forces which are attempting to separate the passages (32,34,36) and (38,40,42). The rings (180) and the hoops (184) are in contact with the core (22) and totally in heat transferring relationship with the donor fluid (20). The rings (180) further expand and contract in response to the temperature changes of the donor fluid (20) and maintain a preestablished force on the core (22) of the heat exchanger (10).
