The efficiency of twisted ribbons using for the intensification of heat transfer in the channels of the cooling system of traction motors is considered. The analysis of the experimental data of a number of authors is presented. The formulas for Reynolds criterion for air in circular and rectangular channels are obtained. It is proved that this method of heat exchange intensification reduces the power of the fans of the engine cooling system.
