Abstract
A heat exchanger header is formed of a tube plate and a header plate having indentations that cooperate with the tube plate to form a row of tank chambers for interconnecting heat exchanger tubes joined to the tube plate. The tube plate has ribs extending between adjacent tube apertures that are contacted at a point midway along their length by respective projections from the indentations on the tank plate.
