The tube especially suitable for flooded evaporator in the central air-conditioner centrifuge, water-cooled screw chilled water units, the shell heat exchanger, as the integral helical fins on the outside of the tube are modified to enhance the initiation of nucleate boiling stes, improving overall heat tranfer coefficient. The inside heat transfer coefficient is improved because of increased surface area and turbulation induced by integral helical ridges on the inside surface.
