Abstract
This study presents an approach to high-efficiency, low-energy liquid cooling using liquid synthetic jet devices. These devices generate dynamic pressure exactly where needed, addressing the inefficiencies of conventional liquid cooling systems. Powered by a piezoelectric actuator, localized, high-velocity jet impingement is achieved with minimal power consumption as low as 50 mW. With a dielectric working fluid as deionized water, liquid synthetic jet impingement showed a heat transfer coefficient of up to 1.52 W/(cm2·K). Compared to existing methods, superior heat removal per unit of consumed power is achieved. This work presents an advancement in sustainable thermal management, with broad potential applications, including immersion cooling in data centers.
