Recent technological advancements have led to a drastic increase in heat flux dissipation, which is prime factor for lower efficiency and permanent failure. Therefore, cooling methods require consistent up-gradation cope with the demand. Among various innovative techniques, microchannel sink has gained much attention. Furthermore, micro pin fin configuration of yielded better performance than conventional due greater convective area, secondary fluid flow, unique vortex production, thinner boundary layers, etc. The present review paper systematically analyses different aspects fin, i.e., its cross-sectional shape, arrangement, density, design parameters. parameters, including aspect ratio, sidewall gap, tip clearance, etc., were thoroughly described, their optimal ranges elaborated. It was observed that formation downstream significantly influences thermo-hydraulic can be analyzed help streamlined plot flow. Based on studies, it concluded single phase flow should sharp-edged cross-section, porosity range 0.5–0.6, clearance 15–25 % channel height, staggered fashion stepped arrangement. there considerable scope fins as like piranha, open ring, lattice structure shown effective compared fins.
