Design and Development of a Cost-Effective Reversible Cooling Fan for Agricultural Tractors.

Agricultural tractors require self-cleaning and cooling technology, especially in hot and dusty environments. This study introduces a novel reversible fan system designed which is incorporating a manually operated lever-type connection mechanism as an alternative to conventional pneumatic systems. Traditional reversible fans often rely on pneumatic actuators for blade rotation control, which can introduce complexity, maintenance challenges, and energy inefficiency. The proposed design replaces pneumatic components with a mechanically optimized lever linkage system, enabling users to manually reverse the fan’s airflow direction with minimal effort. This innovation enhances operational simplicity, reduces dependency on compressed air systems, and low costs as compared to conventional type reversible fan. The lever mechanism, engineered for ergonomic usability, ensures rapid switching between sucker and pusher modes, optimizing the fan’s utility in applications such as dust removal, ventilation, and thermal regulation. Experimental results demonstrate comparable efficiency to pneumatic systems in airflow reversal, with added benefits of improved durability and energy savings. This work highlights the feasibility of manual mechanical solutions in sustainable engineering, offering a cost-effective, user-friendly, and eco-friendly alternative for industrial and domestic environments. The design’s scalability and adaptability suggest broad applicability in settings where reliability and resource efficiency are prioritized.
