摘要：A number of flat tubes, flat tube heat exchangers, and methods of
manufacturing both are described and illustrated. The flat tubes can be constructed ofone, two, or more pieces of sheet material. A profiled insert integral with the flat tube orconstructed from another sheet of material can be used to define multiple flow channelsthrough the flat tube. The flat tubes can be constructed of relatively thin material, andcan be reinforced with folds of the flat tube material and/or of an insert in areas subjectto higher pressure and thermal stresses. Also, the relatively thin flat tube material can
have a corrosion layer enabling the material to resist failure due to corrosion. Heatexchangers having such flat tubes connected to collection tubes are also disclosed, as aremanners in which such tubes can be provided with fins.
