摘要： 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 width and initial outside shoulder radius and being compressed to compress the at least one internal web to a final web width less than the initial web width and a final outside shoulder radius less than the initial outside shoulder radius and defining a plurality of fluid ports.
