Abstract
A heat exchanger manifold ( ) and method of forming a tube port ( ) on the manifold ( ). The manifold ( ) comprises first and second walls ( ) that define an internal passage ( ) and an outer cross-sectional shape of the manifold ( ). The first wall ( ) of the manifold ( ) has a concave outer surface in which the tube port ( ) of the manifold ( ) is to be formed, while the second wall ( ) has a convex outer surface. The tube port ( ) is formed in the concave first wall ( ), such as by piercing. The shapes of the first and second walls ( ) promote the ability of the manifold ( ) to resist deformation when forming the tube port ( ) in the first wall ( ).
