Charge transport and spatiotemporal distribution characteristics of electroconductive pump and integrated optimization design

Abstract

Electroconductive pump-driven active liquid cooling offers a promising avenue for enhancing thermal management in future electronic devices. This paper presents a detailed analysis of the electroconductive pumping mechanism, characterizing its operational states and performance metrics. By employing numerical simulations and theoretical derivations, we elucidate the Coulomb force distribution and its impact on pump functionality. We introduce a novel classification of four operational states of the pump, determined by voltage-induced charge distribution, which has not been systematically characterized before. Additionally, our investigation extends to the influence of structural parameters on pump performance, providing critical insights for optimizing design. Notably, we explore the interaction of electroosmotic flow with the electric double layer and heterocharge layers at micro-scales, establishing guidelines for optimal voltage application. This work advances the understanding of electrodynamic pumping mechanisms and contributes to the broader application of electroconductive pump technology in cooling systems.
