The aim of this study is to analyze the operating energy savings of a liquid desiccant and an indirect and direct evaporative cooling-assisted 100% outdoor air system (LD-IDECOAS) for marine applications. The LD-IDECOAS comprises a liquid desiccant (LD) unit and indirect and direct evaporative coolers (IEC and DEC) to meet the target supply air (SA) conditions. In this study, seawater was used ...

Ultracold atoms are still too hot. This may seem a ridiculous claim—after all, the low-temperature exploits of the purveyors of quantum gases are notorious. Laser cooling can flash-freeze atoms to temperatures in the microand nanokelvin range. In the mid 1990s, researchers followed this with evaporative cooling of atoms out of shallow traps and made the first gaseous Bose-Einstein condensates a...

Rapid development in VLSI Technology anticipates an urgent need for new micro cooling strategies for high heat flux electronic chips. This paper presents a novel high efficiency micropump/evaporator, based on electrohydrodynamic (EHD) forces, high heat flux electronic sensors. The device incorporates a MEMS-based active micro-evaporative surface and temperature sensors into a single package tha...

Increases in microprocessor power dissipation coupled with reductions in feature sizes due to manufacturing process improvements have resulted in continuously increasing heat fluxes. The ever increasing chip-level heat flux has necessitated the development of thermal management devices based on spray and evaporative cooling. This lecture presents a comprehensive review of liquid and evaporative...
