Abstract Passive heat transfer techniques in minichannel sinks (MCHS) provide effective thermal management solutions for high flux applications. The current study introduces a three‐dimensional numerical analysis conducted to explore the flow and characteristics of MCHS utilizing two passive techniques: incorporating pin fins with oblong‐shaped cavities. Four types fin shapes were developed, including tear‐drop (MCOC‐TDPF), pyramidal (MCOC‐PPF), conical (MCOC‐CPF), oval (MCOC‐OPF), respectively. is carried out under laminar regime Reynolds number ranging from 100 1000. overall performance these designs assessed through comparative traditional based on average Nusselt number, friction factor, factor. Among designs, MCOC‐CPF exhibited superior compared other three configurations, maximum factor 2.25 at Furthermore, influence taper ratio ( β ) enhancement also analyzed. values have been considered, namely 1/6, 1/3, 1/2, 2/3. results revealed that = 1/3 achieved an optimal 2.39 Re

The ability to fabricate complex geometric configurations of the laser powder bed fusion technique offers a significant potential for fabricating mini-channel heat sink with discretized features on sidewall. Based this advantage, novel sidewall MCHS (DSF-MCHS) was proposed, and an optimal design multi-objective multi-parameter carried out using genetic algorithm under 20% conditions. optimized DSF-MCHS corresponding continuous (CSF-MCHS) were fabricated AlSi10Mg. performance pressure loss temperature rise evaluated through numerical simulations experiments. results show that average in increases by 27.2% drop decreases 64.9% compared CSF-MCHS over considered flow range, indicating advantage reducing DSF-MCHS. In addition, neural network model trained based available dataset predict achievable reductions varying increase conditions within space, guiding optimization. proposed energy conservation high efficiency transfer applications.
