Experimental investigations of aerodynamic drag of staggered bundles of flat-oval tubes with incomplete transversal fins in the range of Reynolds numbers 600 < < 20000 are performed. New calculation correlations for determining of drag coefficients for 1<3000 are suggested, the impact of basic geometric and regime parameters on aerodynamic drag of bundles are determined. The received calculation depending is possible to use in developing of heat transfer surfaces for “dry” cooling towers and air cooling apparatus and economizers
