Abstract
A method of making a heat exchanger in which extended heat transfer material, such as a fin annulus composed of thin corrugated deformable metal, is installed in annular fluid flow paths defined between concentric tubes. Concepts of electromagnetic forming and metallurgical bonding are used in a unique combination of steps to arrive at a method well suited to economical production and which at the same time assures a high efficiency level of heat transfer and leak protection effects.
