A tank for a heat exchanger comprises a casing including a substantially planar header opening formed therein and a foot disposed on the perimeter of the header opening. The foot forms an outwardly extending flange from which a pair of walls facing each other extend, the walls forming an arcuate shape including a spine extending along an apex of the arcuate shape. The walls each have a corrugated profile adjacent the foot due to the presence of outwardly projecting ribs formed therein. Each of the ribs extend lengthwise from the foot toward the spine, wherein a distal end of each of the ribs is formed adjacent to a neutral stress portion of the casing which undergoes a minimal stress when an internal pressure from a fluid flowing therethrough is applied to the casing. |
