Influencia del tamaño de porosidad en paneles de espuma de aluminio aplicadas como medio de atenuación de temperatura en un prototipo de radiador automotriz.

Abstract

This research work has as objective to evaluate the influence of porosity size in aluminum foam panels for thermal attenuation in automotive radiators of automatic transmission. The methodology included experimental tests on a prototype radiator using different configurations of aluminum metal foam, varying the thickness of the foam and the distance of the hexagonal pore. The experimental results highlighted that aluminum foam panels with hexagonal pores of 12 mm and 10 mm thickness exhibited the best thermal attenuation, this emphasized the importance of careful porosity size selection. Simulation of the aluminum metal foam radiator using ANSYS using the Fluent CFD module supported these findings, demonstrating the effectiveness of the foam in heat dissipation. Compared to the conventional radiator, the metal foam radiator showed a significant temperature reduction, despite its greater weight. The coherence between the experimental results and the simulation reinforced the validity of the virtual model. In conclusion, variation in porosity size was revealed as a critical factor for thermal attenuation, emphasizing the efficiency of aluminum foam panels with 12 mm hexagonal pores, therefore, careful consideration of porosity size was recommended. in the design and selection of materials for automotive automatic transmission radiators, seeking to maximize thermal efficiency and contribute to better performance of the cooling system in vehicles.
