ABSTRACT:
A heat exchanger is formed by a pair of tanks with heat exchanger tubes connected therebetween. The tanks include a header plate with chamber indentions that cooperates with a tank plate to form a row of tank chambers for interconnecting the heat exchanger tubes joined to the header plate. The header plate has a plurality of tube indentations or dimples which extend at adjacent tube apertures and are contacted by a continuous tank rib on the tank plate within each chamber. The ribs and dimples provide substantially uniform contacting and sealing surfaces during brazing to strengthen the assembled header. The tank rib includes tube slots opposing the apertures in the tube plate to provide a stop for insertion of the exchanger tubes.
