The O.V. Roman Institute of Powder Metallurgy has developed a technology for achieving non-uniform pore distribution along the axis of an anti-gravity tube. This technology addresses the need for heat pipes with significantly higher heat transfer characteristics than heat pipes produced in Russia and abroad. The development of modern electronics is associated with a significant increase in the heat flux densities generated by operating microchips, posing new design and technological challenges for cooling system developers. A promising solution to this problem currently lies in the use of heat pipes with more efficient powder capillary structures, specifically, increasing their capillary transport capacity by creating non-uniform pore distribution along the axis of the capillary structure.

This development is export-oriented and is in demand among electronic and electrical engineering manufacturers in the Russian Federation. The products will be sold through direct supply contracts and existing distributors.

The information is published in the Catalogue "100 Best Developments of the NAS of Belarus for the Country's Economy in 2022–2023" pp. 111–112 and the Catalogue "Brands of the NAS of Belarus 2021–2022: List of the Most Important Developments of the NAS of Belarus" 2023, pp. 103–104.

The developed technology for achieving non-uniform pore distribution enables the formation of a pore size gradient along the antigravity pipe axis in the range of 20 to 100 µm. This non-uniform pore distribution increases the permeability of the powder capillary-porous structure, leading to an increase in the heat transfer limit of the heat pipe.
By creating a multilayer powder capillary structure with optimal pore distribution, the heat transfer capacity of the developed antigravity heat pipe is 2.5 to 3 times greater than that of a traditional antigravity heat pipe.
