文摘

Highly nanotextured “fractal-like” nanostructures on nickel-chrome wires improved the pool boiling performance. Vapor bubbles from wire Joule heating formed, whose buoyant rise removed heat and promoted cooling. Hydrophobic texturing is desirable for electronics cooling, which demands low surface temperatures. Fractal-like hydrophilic surfaces increased the number of nucleation sites and the critical heat flux.
