We report novel flexible thermal ground planes (FTGPs) based on heat pipe technology. FTGP’s effective thermal conductivities are much higher than those of copper and graphite heat spreaders’. We report mylaraluminum, copper-Kapton, and all-polymer FTGP prototypes and advanced technologies which will further enable high-performance FTGPs.
Temperature is a dominant factor in the performance, reliability, and leakage power consumption of modern microprocessors. With the advance of technology, thermal problems in microprocessor design get more crucial due to power density of microprocessors. As a result, more researchers have investigated thermal-aware techniques considering many factors such as ambient temperature 1
Two of the major concerns in 3D stacked technology are heat removal and power density distribution. In our work, we propose a novel 3D thermal-aware floorplanner. Our contributions include: 1. A novel multi-objective formulation to consider the thermal and performance constraints in the optimization approach. 2. Two efficient Multi-Objective Evolutionary Algorithm (MOEA) for the representation ...
In this research, the thermal stability and decomposition kinetics of pentaerythritol tetranitrate (PETN) and Pentastite explosives have been studied experimentally using non-isothermal differential thermal analysis (DTA) and thermo-gravimetric (TG) methods at heating rates of 4.0, 6.0, 8.0 and 10.0 °C/min. The kinetic parameter of activation energy (Ea) and critical ignition temperature fo...
Much attention has been paid to the application of low temperature thermal resources, especially for power generation in recent years. Most of the current commercialized thermal (including geothermal) power-generation technologies convert thermal energy to electric energy indirectly, that is, making mechanical work before producing electricity. Technology using a thermoelectric generator (TEG),...
On the basis of key ways of oily waste treatment in Russia which has been described in the article and on the example of oil-contaminated soil (OCS) treatment there can be considered two most widespread technologies: bioremediation and thermal recovery. We developed the process flow sheet of the equipment (UT-2S) for industrial oily wastes treatment on the basis of high temperature air tight de...
Industrial demands for more compact heat exchangers are a motivation to find new technology features. Electrohydrodynamics (EHD) is introduced as a promising phenomenon for heat transfer enhancement mechanisms. Similar to any new technology, EHD has not been understood completely yet and requires more fundamental studies. In boiling phase change phenomena, nucleation is the dominant mechanism i...
Most of the current thermal power-generation technologies must first convert thermal energy to mechanical work before producing electricity. Thermoelectric generation technology, as one entirely solid-state energy conversion method, can directly transform thermal energy into electricity by using thermoelectric transformation materials. A thermoelectric power converter has no moving parts, and i...
