Researchers at Tianjin University have engineered a groundbreaking piezoelectric MEMS synthetic jet cooler. Measuring a mere 6×6.7×2.1 millimeters, this compact device generates a wind speed of 3.4 meters per second while consuming only 69 milliwatts of power. Boasting impressive capabilities, the cooler effectively reduces the temperature of a heat source from 85°C to 55°C. Its convective heat transfer coefficient stands at 72 W/m²K, surpassing conventional passive cooling methods by a factor of three. With an energy efficiency coefficient of 12.7, it significantly outperforms traditional micro fans. This pioneering technology offers a novel approach to addressing the cooling challenges of edge intelligent devices and is poised to accelerate the computational power revolution.
