In order to promote the heat transfer of saturated pool nucleate boiling, three types of screws with different diameters were installed concentrically on a horizontally flat heating surface, As a result, the interstice between male and female screws on the flat heating Surface was found to Supply the bubble nucleus. Heat transfer coefficient Of nucleate boiling increased as the diameter of screw became larger. This heating surface was found to promote heat transfer by up to 3.2 times that of the common horizontal heating surface. Within the range of experimental conditions employed, a dimension less correlation was obtained for the heat transfer of saturated pool nucleate boiling using the horizontally flat heating surface with screws installed concentrically.
