Adaptive Microchannel Heat Sink for Enhanced Thermal Management Using ThermoMechanoSensing

This study introduces an adaptive microchannel heat sink designed to dynamically alter channel geometry, reducing thermal and flow resistances while ensuring uniform surface temperature. Our evolutionary smart adaptive amorphous microchannel heat sink employs ThermoMechanoSensing, a novel technique that leverages material deformation under thermal and mechanical stress for real-time optimization. Channels are equipped with temperature sensors along their length, allowing for dynamic adjustments that improve temperature uniformity and hotspot control. This deformation acts as a flow modulator and creates dynamic microstructures, such as micro-fins and micro-cavities, enhancing heat dissipation. Additionally, a memristor-based sensor system records thermal stress and pressure oscillations, generating precise thermal maps for optimization algorithms. Our research includes extensive literature reviews, numerical simulations, and a comparative analysis with state-of-the-art designs, aiming to optimize flow distribution and surface structure. This innovative approach promises significant advancements in thermal management for various applications.
