This paper explores the recent research developments in high-heat-flux thermal management. Cooling schemes such as pool boiling, detachable heat sinks, channel flow microchannel and mini-channel jet-impingement, sprays, are discussed compared relative to dissipation potential, reliability, packaging concerns. It is demonstrated that, while different cooling options can be tailored specific needs of individual applications, system considerations always play a paramount role determining most...

Boiling water in small channels that are formed along turbine blades has been examined since the 1970s as a means to dissipating large amounts of heat. Later, similar geometries could be found cooling systems for computers, fusion reactors, rocket nozzles, avionics, hybrid vehicle power electronics, and space systems. This paper addresses (a) implementation two-phase microchannel heat sinks these applications, (b) fluid physics limitations boiling passages, effective tools predicting thermal...

Recent developments in applications such as computer data centers, electric vehicle power electronics, avionics, radars, and lasers have led to alarming increases heat dissipation rate, which now far exceeds the capability of air cooling schemes even most aggressive single-phase liquid schemes. This trend is responsible for a recent transition two-phase cooling, capitalizes upon coolant's latent rather than sensible alone achieve several order-of-magnitude transfer coefficient. Three...

This study presents a detailed and thorough parametric of the Leidenfrost point (LFP), which serves as temperature boundary between transition film boiling regimes. Sessile drop evaporation experiments were conducted with acetone, benzene, FC-72, water on heated aluminum surfaces either polished, particle blasted, or rough sanded finishes to observe influential effects fluid properties, surface roughness, contamination LFP. A weak relationship energies LFP was observed by performing droplet...
