Patent ID: 8881797

Claim:
A heat exchanger, comprising: a housing; a first section having a first plate-fin configuration maintained by said housing and having a first inlet and a first outlet; a second section having a second plate-fin configuration maintained by said housing and having a second inlet and a second outlet; and a plurality of heat exchanger layers, wherein each said heat exchanger layer comprises at least one conductive plate extending between said first section and said second section and positioned in proximity to said first and second plate-fin configurations, wherein said at least one conductive plate has internally disposed integral buttons that are in a contacting relationship with said first and second plate-fin configurations, and wherein said buttons are surrounded by a graphite-based heat transferring material, wherein each said heat exchanger layer transfers heat from a fluid flowing in one of said sections to another fluid flowing in the other of said sections, and wherein said sections are positioned such that the fluids' flow is non-intersecting.
