Owing to their high reliability, simplicity of manufacture, passive operation, and effective heat transport, flat heat pipes and vapor chambers are used extensively in the thermal management of electronic devices. The need for concurrent size, weight, and performance improvements in high-performance electronics systems, without resort to active liquid-cooling strategies, demands passive heat spreading technologies that can dissipate extremely high heat fluxes from small hot spots. In response to these daunting application-driven trends, a number of recent investigations have focused on the design, characterization, and fabrication of ultra-thin vapor chambers for proximate heat spreading away from these hot spots. The predominant transport mechanisms and operational limits have been found to be different under these conditions relative to conventional low-power heat pipes. Noteworthy advances in the fundamental understanding of evaporation and boiling from porous microstructures fed by capillary action, and improvements in vapor chamber characterization, modeling, design, and fabrication techniques are reviewed. Characterization of evaporation and boiling from idealized and realistic wick structures, observation of vapor formation regimes as a function of operating conditions, assessment of fluid dryout limitations, design of novel multi-scale and nanostructured wicks for enhanced transport, and incorporation of these high heat flux transport phenomena into device-level models are discussed. These recent developments have successfully extended the maximum operating heat flux limits of vapor chambers.2

“…A number of experimental, theoretical, and numerical studies on boiling heat transfer have been performed since the incident (Phanikumar and Mahajan, 1998;Lallemand, 1998, 2001;Radziemska and Lewandowski, 2001;Yoon et al, 2001;Hetsroni et al, 2002;Nomura et al, 2002;Su et al, 2002a,b, Su andSugiyama, 2007;Kim and Jeong, 2006;Lee et al, 2007;Prakash Narayan et al, 2008). Many experiments (Yao and Chang, 1983;Nishigawa et al, 1984;Carrica et al, 1995;Glebov, 1995, 1996;El-genk and Gao, 1999;Yang et al, 1997;Kim and Suh, 2003;Lee et al, 2003;Kim et al, 2005 have demonstrated the differences in boiling heat transfer for vertical, inclined, and horizontal heated surfaces. The characteristics of heat transfer for upward-facing and downward-facing pool boiling on a horizontal heated surface are different because the vapor generated in boiling cannot readily move from the hot surface to depart from the edge of the downward-facing heated surface.…”
