METHOD FOR FORMING HYDROPHOBIC TEXTURE ON METAL SURFACE Russian patent published in 2021 - IPC F28F13/04 F28F13/18 F28F21/08 

FIELD: heat exchange process intensification.

SUBSTANCE: invention relates to the field of intensification of the process of heat exchange during condensation of steam, can be used in heat exchangers of the shell-and-tube type of combined heat and power plants: condensers, heaters and coolers. The method for forming a hydrophobic texture on a metal surface consists in creating a rough structure, and the rough texture is formed by punching the metal surface with evenly spaced fine solid spherical particles with sizes from 70 to 80 microns and providing contact angles from 140 to 150 degrees on the obtained textured surface.

EFFECT: invention simplifies the formation of hydrophobic properties of metal surfaces and increasing the efficiency of the heat transfer process in shell-and-tube heat exchangers by creating a rough hydrophobic texture on the heat transfer surface.
