Abstract
The progressive miniaturization of electronic components alongside escalating power densities has generated unprecedented thermal management challenges, with heat flux values attaining 10⁴ W/cm² in specialized applications. Microchannel heat sinks (MCHSs) have established themselves as a highly effective cooling solution owing to their exceptional heat dissipation capacity and favorable surface-area-to-volume characteristics. This review synthesizes findings from previous investigations, encompassing heat transfer enhancement approaches, including rib structures, cavity configurations, pin-fin arrays, and biomimetic designs, advanced working fluids, flow instability phenomena, machine learning implementations, and multi-objective optimization strategies.
