Abstract

A flat tube block heat exchanger with a plurality of flat tubes with deformed ends. The deformed ends have broad sides that have been deformed to expose the inner surface of the flat tubes. The exposed inner surfaces of the flat tubes are bonded to the exposed inner surface of an adjacent flat tube. The bonded inner surfaces of the adjacent flat tubes form a fluid barrier with tanks located at opposite ends of the flat tubes.
