Abstract: An inspection system is configured to inspect the condition of a braze joint formed within a structure, wherein the braze joint is formed from a braze filler material having a tracer material disposed therein. The inspection system includes an energy source for directing energy towards the structure, an energy detector for detecting information regarding the structure following interaction with the energy directed from the energy source, and a data analysis system for analyzing the information detected by the energy detector. The data analysis system is configured to distinguish the tracer material from the remaining materials forming the structure in order to determine a suitability of the braze joint.

Abstract: 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.

Abstract: A heat exchanger includes a plurality of plates in stacked relation forming a plurality of fluid channels therebetween. Ports formed in each of the plates are arranged and substantially align to form an inlet manifold and an outlet manifold for receiving a working fluid therein, wherein the inlet manifold is in fluid communication with an inlet conduit and the outlet manifold is in fluid communication with an outlet conduit. A temperature manipulation element is disposed in at least one of the inlet conduit and the outlet conduit to manipulate a temperature of the working fluid flowing therethrough.
