Abstract

Two-phase cooling systems have a high potential for solving problems of heat removal from the surface of powerful components of microelectronics (chips, microprocessors), LEDs, and solar cells. In this context, a stratified flow regime is of great interest for heat transfer enhancement in such systems. With the development of additive technologies, new opportunities are given to intensify heat transfer by creating highly intelligent surfaces. The paper presents a study of heat and mass transfer of a two-phase system in a minichannel with a local heating source. The surface of the heating element has a periodic columnar structure with characteristic size (diameter and height) equal to 300 um, produced using additive technologies.
