چکیده مقاله
Efficient thermal management of high heat flux electronic components demands heat sink designs that enhance convective heat transfer while limiting the associated hydraulic penalty This paper presents a systematic multi objective Pareto optimization of a hybrid microchannel heat sink MCHS that integrates oblique micro grooves with a circular micro pin fin array Three dimensional conjugate heat transfer simulations are coupled directly with a MOGA II NSGA II based evolutionary algorithm to optimize four geometric variables: groove width Wg , groove inclination angle 0 , pin fin diameter DP , and fin region length Lf The optimization is performed independently at Reynolds numbers of,,, and V under a constant heat flux of W/cm², resulting in A high fidelity CFD evaluations The objectives are formulated as maximizing the Nusselt number enhancement ratio and minimizing the pressure drop ratio relative to a straight channel baseline The best Pareto designs achieve a thermo hydraulic performance index of n = 1, 91_, E, increase the Nusselt number by Y 19%, and simultaneously reduce the pressure drop by 1 1% relative to the baseline, while lowering the outlet temperature by Y,9_1Y, EA K The optimal configurations converge to a robust design family WgVY mm, L₁ = 9,1 mm, 0 = YA_Y9° , demonstrating practical single geometry applicability across the investigated operating envelope The results provide a quantitative, trade off aware design map for compact liquid cooled cold plates in power dense electronic modules
