Abstract
A heat exchanger core and header of the fin and tube type is provided having a plurality of tubes disposed in generally axially parallel and spaced apart relation, a fin assembly between adjacent tubes, a header plate at one end of said tubes, said header plate having a series of openings therein adapted to receive said tubes and generally uniformly spaced from the sidewalls of said tube ends, an elongate ferrule in each said opening substantially filling the area between said openings and said tubes and extending axially along said tubes from said header at least on the side opposite the fins and a metallurgical bond between the ferrule and tubes and between the ferrules and header.
