Overview

Experimental study demonstrates enhanced pool boiling heat transfer on microstructured copper surfaces, indicating potential for high-performance thermal cooling systems.

Key Points

To evaluate the impact of electron-beam surface microstructuring on nucleate pool boiling heat transfer performance in distilled water under atmospheric pressure.
Fabricated copper test specimens with three microrelief geometries (star-shaped patterns via forward and reverse scanning modes, and a linear pattern) using electron-beam Surfi-Sculpt processing.
Conducted nucleate pool boiling experiments on smooth and modified copper surfaces in distilled water at atmospheric pressure to determine boiling curves and heat transfer coefficients across heat fluxes.
Modified surfaces shifted boiling curves toward lower wall superheats relative to a smooth copper baseline.
Electron-beam microstructuring increased both the heat transfer coefficient and critical heat flux, with performance mediated by microrelief geometry effects on nucleation site density, liquid feeding, and vapor escape.
