ANALYSING THE EFFICIENCY OF USING POROUS METALS IN HEAT EXCHANGERS

This study focuses on analysing the effectiveness of porous metals in heat exchangers, focusing on their effect on improving heat transfer processes. Porous metals, due to their unique structure, have high thermal conductivity and increased contact surface area, which contributes to more efficient heat transfer. As part of the study, experiments and theoretical analyses were carried out to evaluate the effect of porosity coefficient on heat exchange performance. The plotted dependence of Freon mass flow rate and heat quantity on porosity coefficient demonstrate the linear nature of these dependencies. Mathematical processing of the data showed that an increase in the porosity coefficient leads to an increase in both the amount of heat transferred by Freon and Freon mass flow rate, indicating an increase in heat exchange efficiency. The results confirmed that porous metals can significantly improve the performance of heat exchangers and energy saving. Based on the study, further investigation and implementation of porous metals in heat exchangers is recommended to optimise their performance and improve the overall system efficiency. These results open new perspectives for the application of porous metals in various industries including power and mechanical engineering.
