Abstract Experimental studies of the heat transfer of surfaces with split ribs under the natural convection were carried out. The effect of the casing shrinkage and the angle of rib lobes extension on the heat transfer intensity was shown. In order to analyze the data of test experiments, the calculations were performed using the M.A. Mikheev and V.P. Isachenko dependencies for a smooth rib. The optimal parameters of the casing height and the angle of rib edges extension corresponding to the best heat transfer were revealed. The heat transfer coefficients of the smooth and split ribs were compared, the efficiency of using split ribbing was evaluated.
