Abstract
A reduction in tube to header joint failures in a heat exchanger having spaced headers (), elongated, side-by-side parallel spaced tube slots () in the headers () along the length thereof and a plurality of flattened tubes () having ends () received in the tube slots () and metallurgically bonded to the header () thereat was achieved through the use of a reinforcing structure () having at least two projections () having a cross sectional shape complimentary to at least a part of the surface of the tubes () at their ends () and a length sufficient to extend along the tube ends () to a location past the metallurgical bonds between the tube ends () and a header (), and a spine () extending transverse to the projection. Also disclosed is a reinforcing structure () and a method of reinforcing the tube to header joints in a heat exchanger.
