ABSTRACT:
An elongated heat exchanger tube has an internally located stiffener assembly which prevents the deflection of the tube wall due to pressure differentials between the tube internal and external surfaces while allowing the flow of fluid between the areas on opposite sides of the stiffener inside of the tube. The heat exchanger tube can have an elliptical, oval or flat cross-section. The internal stiffener can have a variety of cross-sectional configurations having uniform or non-uniform shapes.
