Cross-counterflow heat exchanger assembly

摘要

A manifold for use in a heat exchanger assembly (20) and a method of forming the manifold is disclosed herein. The method starts with the step of separately forming a first member (22) at least partially defining an interior and having a spaced set of first tube slots (30) and a second member (32) having a wall (36) positioned against the first tube slots (30) and dividing the interior into a plurality of chambers (38, 40). The method is finalized with the step of permanently fixing the first member (22) to the second member (32) to define an first manifold (42) after the separately forming step.
