Abstract
There is disclosed a tube-to-header joint arrangement for a heat exchanger wherein the tubes include an oblong or flattened body which is off-set to one side with respect to cylindrical ends formed on the tubes. The off-set bodies facilitate staggering alternate rows of collared openings formed in the header to thereby maintain a predetermined minimum distance between adjacent collars to avoid fatigue or failure of the header, while permitting maximum diameter openings to be employed for maximum surface area contact between each tube and header collar for a stronger joint therebetween.
