The growth of electrical devices necessitates efficient cooling systems, but the development of cooling fan propellers has lagged due to the coherent dependence on conventional propeller designs. Recent advancements in cooling technology for electric vehicle battery packs involve numerous developments yet cost and space constraints are some of the persistent challenges. Increasing the number of cooling fans leads to excess power consumption and reduced system efficiency. Adjusting the battery pack’s structure can help lower temperature, but large air openings risk debris ingress and require high-quality filters, reducing air density and creating pressure drops. This lowers the mass flow rate through the fans, increasing battery pack temperature and affecting efficiency. This paper aims to focus on the development of propellers with enhanced mass flow rate obtained by implementing different airfoil geometries in the designing of the propeller, analyzing their effect, and proceeding with the performance analysis with an existing design.
