Flat turbulator for a tube and method of making same

摘要

A tube and turbulator and method of making the same for a heat exchanger including a base (24), a top (26) spaced from and opposing the base (24), a first side (28) interposed between the base (24) and the top (26) along one side thereof, and a second side (30) interposed between the base (24) and the top (26) along another side thereof. The base (24), top (26), first side (28) and second side (30) form a channel (32). The second side (30) is triple hemmed such that ends of the base (24) and the top (26) are disposed within the channel (32). A flat turbulator (54) 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 (58) spaced laterally along a base (56) and extending longitudinally and generally perpendicular to the base (56) in an alternating manner. The corrugations (58) are formed by rolling a generally planar strip.
