The short review concerning the intensification of heat emission at interaction different heat transfers with a warmed surface is presented. Results of an experimental research of heat transfer are shown at boil impinging jets of Freon R-134a on mini- and microribbed surfaces in conditions of stationary heating with reference to evaporate cooling systems of high-power components of radio-electronic equipments. Influence of the form of a heat exchange surface on heat emission and thermal resistance is revealed.
