A folded tube and method of making the same for a heat exchanger includes a base, a top spaced from and opposing the base, a first side interposed between the base and the top along one side thereof, and a second side interposed between the base and the top along another side thereof. The folded tube includes at least one of the base and the top having at least one internal web having an initial web height and being compressed to extend the at least one internal web to a final web height greater than the initial web height and defining a plurality of fluid ports.
