Abstract: A folded tube for a heat exchanger is disclosed. The tube includes first and second ends for connection to first and second headers of the heat exchanger. An outer wall of the tube provides at least two channels for carrying a heat exchange fluid between the first and second headers. At least one seam is formed in the outer wall extending the length of the tube, the seam including a pair of opposed flanges extending into the tube to form the two channels, the outer wall joined together along the seam. The tube further includes a first end region and a second end region, and an intermediate region. The tube flattened along its length to form at least two flattened lobes, each lobe including one of the channels, and the lobes in the intermediate region being flatter than the lobes in at least one of the end regions.
