A tube and turbulator and method of making the same for a heat exchanger including 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 base, top, first side and second side form a channel. The second side is triple hemmed such that ends of the base and the top are disposed within the channel. A flat turbulator may be disposed inside the tube and includes a base extending laterally and longitudinally in a strip. The flat turbulator also includes a plurality of corrugations spaced laterally along the base and extending longitudinally and generally perpendicular to the base in an alternating manner. The corrugations are rolled in a direction parallel to a longitudinal axis of the strip.

1. A method of making a flat turbulator for a heat exchanger comprising the steps of:providing a generally planar strip having a base extending laterally and longitudinally; roll forming a plurality of corrugations spaced laterally along the base and extending longitudinally a distance greater than a distance laterally, the corrugations extending generally perpendicular to the base in an alternating manner from opposed sides of the base such that the corrugations extend in a direction parallel to a longitudinal axis of the strip and with each adjacent alternating corrugations being spaced from one another such that the base extends between the adjacent alternating corrugations.
