This work presents the development and experimental characterization of innovative heat sinks fabricated from sintered aluminum metallic sponges, specifically designed to improve thermal efficiency in electronic systems. The research is based on the growing challenge of properly managing the heat generated by electronic components, whose prolonged exposure to high temperatures compromises both their performance and their lifespan. Using aluminum burr as raw material, prototypes were fabricated by compression at two load levels (1.5 and 2.5 tons) and subsequent sintering at temperatures of 550°C and 650°C for 45 and 75 minutes, according to a Taguchi L4 experimental matrix. Thermal performance was evaluated by applying an electrical load controlled by a solid-state relay (SSR), recording the thermal response of each configuration. The results reveal that the heatsink sintered at 550°C for 45 minutes and compressed to 1.5Tn (P1.5T550A) achieved a 16.7% improvement in thermal efficiency compared to a Solid Metal Heat Sink (SMHS), validating the potential of this technology as an efficient and sustainable solution for thermal management in advanced electronics.
