Abstract
In recent times, the subject of effective cooling have become an interesting research topic for electronic and mechanical engineers due to the increased miniaturization trend in modern electronic systems. However, fins are useful for cooling various low and high power electronic systems. For improved thermal management of electronic systems, porous fins of functionally graded materials (FGM) have been identified as a viable candidate to enhance cooling. The present study presents an analysis of a convective–radiative porous fin of FGM. For theoretical investigations, the thermal property of the functionally graded material is assumed to follow linear and power-law functions. In this study, we investigated the effects of inhomogeneity index of FGM, convective and radiative variables on the thermal performance of the porous heatsink. The results of the present study show that an increase in the inhomogeneity index of FGM, convective and radiative parameter improves fin efficiency. Moreover, the rate of heat transfer in longitudinal FGM fin increases as β increases. The temperature prediction using the Adomian decomposition method is in excellent agreement with other analytical and method.

Summary
Increased miniaturization in modern consumer electronics has motivated research on thermal management of high-performance microprocessor-based systems by mechanical and electronic designers. In recent times, have conducted research using the analytical, numerical and experimental methodology to investigate the effects of various thermal parameters on fin performance [10,11,12,13,14,15,16]. Present an experimental analysis of flow and heat transfer in a miniature porous heat sink for high heat flux applications These studies explore the convective, radiative and various thermal parameters of the heatsink using the properties of conventional airflow, features of channel cross-section, variable geometries and air flow paths. The present work focuses on the analysis of a porous FGM heatsink operating under a convective–radiative environment for improved cooling low and high power electronic systems.
