Confinement effects on nucleate boiling and critical heat flux in buoyancy-driven microchannels
TL;DR: In this paper, vertical, rectangular parallel-plate channels were immersed in dielectric liquid FC-72 at atmospheric pressure to elucidate the effects of geometrical confinement in immersion cooled electronics applications.

TL;DR: In this paper, a shape of the lightguide is used to cause and direct extraction of light from a solid state light source, and the shape can also be used to create a particular pattern of the extracted light.

Journal ArticleDOI
Passive Immersion Cooling of 3-D Stacked Dies
TL;DR: In this paper, a methodology for the optimization of immersion cooled 3-D stacked dies is presented, including the effects of confinement on natural convection and channel boiling, and the optimal die spacings for both single and two phase cooling with saturated FC-72 are found to be on the order of half a millimeter for typical microelectronics geometries.
