To develop a dual-bionic micro/nano-structured surface inspired by pitcher plants and phalarope beaks to control bubble departure dynamics and enhance microchannel flow boiling performance.
Designed and fabricated microchannel heat sinks featuring dual-bionic micro/nano-structures that emulate the peristome micro-ratchets of Nepenthes alata and the wedge-shaped beak of a phalarope.
Evaluated flow boiling thermo-hydrodynamic performance at a mass flux of 600 kg·m⁻²·s⁻¹ and tested heat dissipation on a commercial CPU operating at full power.
Achieved a critical heat flux of 366.5 W·cm⁻² and a heat transfer coefficient of 11.8 W·cm⁻²·K⁻¹ at 600 kg·m⁻²·s⁻¹, representing increases of 82.5% and 103.2% compared to smooth microchannels, respectively.
Facilitated spontaneous bubble migration from ratchet roots to tips via an interfacial energy gradient, followed by rapid bubble departure driven by combined buoyancy and drag forces.
