Abstract
Preformed articles of an amorphous metal foil which are particularly adapted to be used in the manufacture of an assembly having brazed joints, especially a heat exchanger. Methods for the manufacture of a heat exchanger or other assembly having brazed joints, which method includes the process step of providing a preformed article formed of a brazing foil composition of an amorphous metal alloy in contact with one or more elements of said heat exchanger or other assembly.
Claims11
A preformed article, comprising an amorphous metal by brazing foil having an irreversibly deformed, non-planar, three dimensional configuration including a primary planar face with at least one perforation passing therethrough, said article being adapted for use in the manufacture of an assembly, said manufacture comprising the brazing of a plurality of tubes to at least one plate, and the brazing of said plate to a shell encasing said plurality of tubes and said at least one plate.
A heat exchanger or other assembly having brazed joints which is manufactured by a method that includes the process step of providing a preformed article formed of a brazing foil composition of an amorphous metal alloy incontact with one or more elements of said heat exchanger or other assembly, said preformed article having an irreversibly deformed, non-planar, three dimensional form having contours fitting said one or more elements of said heat exchanger or other assembly and a primary planar face with at least one perforation passing therethrough.
