Plasma Actuator for Electronics Cooling
We developed a Dielectric Barrier Discharge (DBD) plasma actuator optimized for electronics cooling. By generating a high-velocity ionic wind across heated surfaces, it enhances forced convection without fans or moving parts. Experiments show significant increases in local heat transfer, enabling lower surface temperatures and improved thermal stability under high power densities. The actuator operates at low power, produces no vibration and can be integrated directly onto heat sinks, PCBs, or chip packages. This technology provides a compact, solid-state cooling solution that supports higher device performance, extended lifetime and new thermal management architectures in next-generation electronics.
The prototype is designed to provide solid-state active cooling for high-power electronics using plasma-induced ionic wind. Its practical applications include cooling CPUs, GPUs, SSDRs, power modules, EV inverters, LED drivers, telecom equipment and compact embedded systems where traditional fans or heat sinks are insufficient. By boosting local heat transfer without moving parts, the technology enables higher power densities, lower operating temperatures, reduced thermal throttling and longer device lifetime, while also allowing quieter, smaller, and more reliable thermal designs.
