A heat exchanger includes a plurality of first plate assemblies interleaved with a plurality of second plate assemblies in stacked relation. Each of the plate assemblies includes a flow path for receiving a working fluid therein. Ports formed in each of the plate assemblies are aligned to form an external inlet manifold and an external outlet manifold in fluid communication with the flow paths. Leakage and contamination of the working fluids are minimized by separating the flow paths of the respective working fluids with adjoining double walls and by providing separate external working fluid manifolds. |
