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.
用于高通量电子冷却的液体合成射流
本研究提出了一种利用液体合成射流装置实现高效、低能耗液体冷却的方法。这些装置在需要的地方产生动态压力,解决了传统液体冷却系统效率低下的问题。在压电驱动器的驱动下,局部高速射流撞击以低至50兆瓦的最小功耗实现。当介质为去离子水时,液体合成射流冲击传热系数高达1.52 W/(cm2·K)。与现有的方法相比,实现了单位消耗功率的优越散热。这项工作展示了可持续热管理的进步,具有广泛的潜在应用,包括数据中心的浸入式冷却。
