CONNECTING HEAT EXCHANGER TUBES TO A TUBE HEADER.

A method of securing in fluid tight relation the spaced ends of straight legs of heat exchange tubes of a U-shaped matrix to a tubular fluid conveying duct is effected by bending the spaced ends of the straight legs of the matrix to reduce the spacing between the ends of the tubes, thereafter loosely gathering the ends of the tubes to bring them into contact along their surfaces and then encircling the loosely gathered tube ends with frame elements which apply compression forces to the tube ends to deform then and cause them to come into contact with one another over substantially the entire surface areas thereof. The tube ends are then heated to braze them together and unite them with the frame elements as a unified block assembly. The block assembly is then inserted into an opening of conforming shape in the tubular fluid conveying duct and joined to the duct in sealed relation.
