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