Methods and apparatus for isolating a heat exchanger core from external ducting coupled to the heat exchanger manifolds. A flexible metal bellows of the externally pressurized type is utilized at each juncture between the inlet and outlet air ducts and the associated integral core manifolds. Similar arrangements are provided at the opposite side of the heat exchanger core where blind ducts are incorporated for balancing of the compression load forces and for access to the manifolds for inspection and maintenance.

Method and apparatus for isolation of external loads in a heat exchanger

Air at substantially ambient pressure is cooled in a heat exchanger and introduced into an enclosure for cooling. The air is withdrawn from the enclosure and a portion of the air is expanded through a turbine for additional cooling and passed through the heat exchanger for the removal of heat therefrom. The air is then compressed to substantially ambient pressure and expelled. Additional cooling of the expanded air from the turbine may be obtained by evaporating a fluid therein. The fluid may be water condensed in, and withdrawn from, the heat exchanger.
