Abstract:
1. A process for manufacturing a heat exchanger manifold, comprising a) providing an overmolding insert comprising a base having at least one first opening in a first said surface, said first opening being in communication with a corresponding second opening in a second surface opposite said first surface, said overmolding insert further comprising two opposed side walls, each side wall being joined to said first surface, two opposed end walls being joined to an opposite end of said first surface and extending from one side wall to the other side wall, such that the side walls, the end walls and the first surface define a partially closed space, wherein said second surface is only bonded to said end walls and said side walls; b) removably inserting a removable projection into said opening in a first surface of said overmolding insert such that the projection extends from said first surface and beyond said partially closed space, c) fitting an end of a hollow conduit which extends beyond said partially closed space and has an opening in communication with said first opening of said first surface over said removable projection; d) molding molten polymeric material over said overmolding insert and said hollow conduit end to form a manifold; and e) removing said removable projection from said manifold.
