On-Chip Two-Phase Cooling with Refrigerant 85 mu m-Wide Multi-Microchannel Evaporator Under Hot-Spot Conditions

John Richard Thome, Stefano Nebuloni, Jonathan Olivier, Etienne Costa-Patry

Hot-spots are present in micro-electronics and are challenging to cool effectively. This paper presents highly nonuniform heat flux measurements obtained for a pseudo-CPU with 35 local heaters and temperature sensors cooled by a silicon multi-microchannel ...

A versatile scheme for read-out and actuation of nanomechanical motion using silica microspheres

Tobias Kippenberg, Emanuel Gavartin

We employ silica microspheres to detect and actuate nanomechanical motion. With Si3N4-nanostrings, we achieve significant passive cooling by radiation pressure. Feedback-cooling enables stable operation at optical powers beyond the parametric-instability t ...

Comprehensive Performance Metrics for Complex Fenestration Systems Using a Relative Approach

Buildings account for over 40% of the energy consumption in the United States, nearly 40% of which is attributed to lighting. The selection of a fenestration system for a building is a critical decision as it offsets electric lighting use as well as impact ...

Smart Building Designer: Eine Methode zur optimalen Auslegung von komplexen Gebäudesystemen

Araz Ashouri

As decided by the European Parliament in April 2009, starting from 2019, new buildings must be so-called net-zero energy buildings. The capital cost of these building systems and thus the potential for optimization will increase significantly. In addition, ...

On-Chip Cooling of Hot-Spots with a Copper Micro-Evaporator

John Richard Thome, Etienne Costa-Patry

Hot-spots are present in micro-electronics and are challenging to cool effectively. Using a copper micro-evaporator mounted on a pseudo-chip, on-chip two-phase cooling was found to very effectively cool the hot-spots without inducing flow instabilities. Bu ...

Heat Transfer and Performance Characteristics of Axial Cooling Fans with Downstream Guide Vanes

Peter Ott, Alexandros Terzis

This study examines experimentally the effect of stators on the performance and heat transfer characteristics of small axial cooling fans. A single fan impeller, followed by nine stator blades in the case of a complete stage, was used for all the experimen ...
