Piranha Pin-Fins (PPF): Voracious boiling heat transfer by vapor venting from microchannels - system calibration and single-phase fluid dynamics

Abstract

A novel approach to embedded electronics cooling with a multi-phase microfluidic heat sink termed the Piranha Pin-Fin (PPF) is presented. Several first-generation PPF devices, as well as plain-channel and solid pin-fin heat sinks, have been fabricated and experimentally tested under single-phase adiabatic conditions. Details of the PPF device geometry and microfabrication process are provided. Plots showing pressure drop and friction factor are also provided.
