Air Cooling of High-Heat-Flux Electronics Using Wettability-Engineered Vapor Chambers
… Novel strategies in thermal management -like vapor chambers, thermosyphons, and oscillating heat pipes- transport heat from one place to another or spread heat over a wider area, often reducing high fluxes, allowing traditional methods to perform better and handle higher heat loads. Recent …

Developing an active, high-heat-flux thermal management strategy for power electronics via jumping-droplet phase-change cooling
… setup was developed to remove heat via droplet evaporation from single and multiple high-power gallium nitride (GaN) transistors acting as local hot spots (4.6 mm x 2.6 mm). An externally powered circuit was developed to direct jumping droplets from a copper oxide (CuO) nanostructured …

Enhanced phase change heat transfer through advanced fabrication techniques
… change during operations. Heat transfer during vapor to liquid phase change or condensation is a critical industrial operation, determining the efficiency and costs of several processes. It is well established that dropwise condensation of water vapor has 10 – 20 times higher heat transfer …

Thin-film evaporation from well-defined silicon micropillar wicks for high-heat-flux thermal management
… space and commercial applications. Liquid to vapor phase-change strategies are promising due to the high latent heat of vaporization of the working fluid. In particular, capillary pumped thin-film evaporation from micropillar wicks has received significant attention owing to advances in …

Three-Phase and Unidirectional Heat Transfer
… In the forward mode of operation, water evaporates from the heated wicked plate and condenses on the opposing hydrophobic plate. The large contact angle of the dropwise condensate enables bridging across the gap to replenish the wicked evaporator, providing sustained phase-change heat …
