--Day by day a huge measure of research is proceeding to discover the cooling solutions for electronics including various applications for CPU, LED coolers, relay cooling frameworks. The serious issue including electronic parts cooling is the structure of heat sinks and their compatibility with the electronics for the predefined applications. Likewise, the quick-paced progressions in computing driving for the production of superior processors with incorporated complex circuits for which the cooling turned into a troublesome task which became challenging the existing market. This study targets building up a metal matrix composite (MMC) heat sink for low coefficient of thermal expansion (CTE) in electronic parts. Aluminum nitrate (AlN) takes like 12.5% (wt/wt) and mixed Aluminum (Al) to form metal matrix composite (MMC) prototype heat sinks. Prototype metal matrix composite (MMC) properties were evaluated experimentally. The modeling of the laterally perforated finned heat sink (LA-PFHS) is done Solid-works. The sinks are fabricated by using CNC machining. Two configurations of circular piercings on the fins are used in which the diameter and the spacing between piercings vary. In a rectangular insulated duct, the experimental analysis on the three metal matrix composite (MMC) heat sinks was performed under the phenomenon of forced convection at varying heat fluxes and at ambient conditions of temperature 30°C, pressure 101.326 KPa and 45% humidity. From 1.0 m/s to 4.0 m/s wind velocities and with an interval of 1 m/s the experimentation were carried out. Results show that the model III prototype metal matrix composite (MMC) heat sink proposed in this study shows a decrease in thermal resistance (Rth) by 50.51 %.
