Spray cooling has a wide range of applications, such as quenching metal slabs during casting, cooling nuclear reactors, suppressing accidental fires, and dissipating heat from high-power density electronics. With the miniaturization of electronic devices, the power density or heat flux on their surfaces increases, leading to potential thermal shutdown if proper cooling is not provided. Surface nanotexturing plays a crucial role in enhancing cooling capability and improving the effective heat transfer coefficient by increasing the liquid-to-substrate surface area. Moreover, the dynamic wettability of the surface in spray cooling significantly influences drop impact dynamics and subsequent evaporation of the coolant on the hot surface. In this study, we introduced a variety of nanotextured surfaces, including thorny-devil nanofibers, nickel nanocones, Teflon, TiO₂, ZnO NWs, and Cu pyramid/ZnO according the mesh size (fine or coarse) to investigate their effects on drop impact phenomena and evaporative cooling. These nanotextured surfaces were fabricated using different deposition techniques such as electrospinning, electroplating, supersonic spraying, aerosol deposition, and chemical bath deposition. We observed that surfaces with higher dynamic wettability, particularly those exhibiting hydrodynamic focusing like the thorny-devil nanofiber surface, significantly improved heat removal by extending the Leidenfrost limit and promoting drop spreading. Notably, the thorny-devil nanofiber surface exhibited the highest heat flux across various ranges of the Reynolds and Weber numbers. To validate the effectiveness of these surfaces in practical applications, spray cooling experiments were conducted on a model electronic kit, and the results confirmed that the thorny-devil nanofibers were the most efficient in cooling the surface during multiple cycles of water spraying.
