Summary: The paper presents a review of current solutions and trends in cooling systems for forestry machinery operating under severe climatic conditions. The study examines the design and parameters of radiator impellers, their impact on engine energy efficiency and reliability, as well as the features of various drive types — mechanical, electric, and hydraulic ones. Data from domestic and foreign manufacturers covering 31 models of forestry machines were analyzed, and existing approaches to improving cooling efficiency and reducing energy consumption were evaluated. Based on the analysis, it was found that the most common impellers in the industry are those with a 700 mm diameter, used in engines of the D-260 family. According to the comparative assessment of structural and operational characteristics, the serial impeller model AMK700.001.00.000 was selected as the baseline for further optimization. Future research will focus on creating a digital twin of the selected impeller, conducting numerical simulations using CFD and acoustic analysis, and developing criteria for improving aerodynamic and operational performance. The review results may be applied to modernizing the cooling systems of domestic forestry equipment with minimal costs and without major design modifications.
