CFD Analysis of Heat Transfer Enhancement in Microchannel Heat Sinks

The rapid advancement of electronic devices, high-performance computing systems, and compact thermal management technologies has increased the demand for efficient heat dissipation solutions. Microchannel heat sinks have emerged as promising cooling technologies due to their high surface-area-to-volume ratio, compact structure, and superior heat transfer capabilities. This study focuses on the Computational Fluid Dynamics (CFD) analysis of heat transfer enhancement in microchannel heat sinks by investigating the influence of different geometrical configurations, flow characteristics, and operating parameters on thermal and hydraulic performance. Numerical simulations are proposed to examine the effects of channel dimensions, channel shapes, inlet velocity, coolant properties, and applied heat flux on temperature distribution, pressure drop, heat transfer coefficient, and overall thermal resistance.
