Abstract

This paper explores the selection of processing techniques for evaporative cooling fins applicable to the lubricating oil cooling in rotary kilns, with a specific focus on the application of a hydrophilic coating. Experimental comparisons were performed on different coating sample materials, evaluating their capillary absorption height and saturated water absorption state. The results demonstrate that both plant fiber nonwoven fabric and polyester fiber nonwoven fabric exhibit excellent hydrophilicity. Comparative experiments were further conducted on the cooling effects of regular fins, evaporative fins covered with plant fiber nonwoven fabric, and evaporative fins covered with polyester fiber nonwoven fabric. Additionally, the evaporation rates of fins covered with plant fiber nonwoven fabric and polyester fiber nonwoven fabric were compared. The findings suggest that superior hydrophilicity of the hydrophilic coating material corresponds to enhanced cooling efficiency and evaporation rates. Therefore, fins coated with plant fiber nonwovens with excellent hydrophilicity have great potential in evaporative cooling systems.
