%X The results of experimental investigation of mini/micro-scale heat transfer of two-phase flow (propane) conducted at the heat flux range 102-105 W/m2 are presented. Investigation of pool boiling and evaporation heat transfer in mini-channels on a single horizontal tube (smooth and with porous coating) was performed for the reasons of analysis of its cooling efficiency. The data obtained on a flooded and partially flooded horizontal tube with porous coating in liquid pool or in confined space (from 0.1 to 2 mm) testify the phenomena of micro-heat pipe inside a porous structure. A micro-scale effect took place inside the porous body and a mini-scale effect was ensured due to a flank or annular mini-channel. Visual analysis and experimental results show that such combination is favorable for enhancement of evaporation and two-phase convection heat transfer. The availability of annular mini-channel significantly promotes to intense heat transfer (up to 2.5−3 times as high) at heat fluxes up to 50 kW/m2 , as compared with the process in liquid pool.
