Thermoelectric (TE) energy scavenging in high performance microelectronic systems has not been sufficiently developed in the past for practical use due to lack of methodology to minimize the impact of such power generation on performance. This paper describes an empirically based method to enable harvesting of excess heat with examples from ongoing work. The scheme involves detailed characterization of TE modules and notebook systems, along with co-development of correlated system models for the optimization of TE integration. As the iteration of models and measurements converge, the available energy from heat is quantified with high confidence. All of our studies have been performed with the goal of maximum power generation and minimum impact on performance.


Empirical Proof of Concept for TE Generation in Mobile Computers
Denker, Reha; Muhtaroglu, Ali; Külah, Haluk (2012-12-05)
Thermoelectric (TE) module integration into a mobile computer has been experimentally investigated in this paper for its energy harvesting opportunities. For this purpose, a detailed Finite Element Analysis (FEA) model was constructed for thermal simulations. The model outputs were then correlated with the thermal validation results of the target system. A suitable "warm spot" has been selected, based on the FEA model, to integrate a commercial TE micro-module inside the system with minimum or no notable im...
Empirical feasibility analysis of thermoelectric energy harvesting in thermally limited compact mobile computers
Khan, M. A. A.; Muhtaroglu, A. (AIP Publishing, 2014-01-01)
Thermoelectric (TE) generation technology was experimentally established in previous research by our group as a viable technique for energy scavenging in a large notebook computer with no significant impact to system performance. The computer under investigation was designed to have additional thermal headroom, with Central Processing Unit (CPU) temperature significantly below its maximum limit under maximum workload conditions. Yet the question remained on if and how such scavenging could be done in small,...
Composite index for benchmarking local energy systems of Mediterranean port cities
Kılkış, Şiir (2015-12-01)
Benchmarking the performance of local energy systems requires an integrated approach. This paper develops a composite index that consists of a unique set of 7 dimensions and 35 main indicators. The SDEWES (Sustainable Development of Energy, Water, and Environment Systems) Index is applied to a sample of 22 Mediterranean port cities. The index integrates energy and CO2 emissions data from SEAP (Sustainable Energy Action Plans). The values of the indicators are aggregated based on the Min-Max method for a fin...
Quasi-dynamic model for an organic Rankine cycle
Bamgbopa, Musbaudeen O.; Uzgoren, Eray (Elsevier BV, 2013-08-01)
When considering solar based thermal energy input to an organic Rankine cycle (ORC), intermittent nature of the heat input does not only adversely affect the power output but also it may prevent ORC to operate under steady state conditions. In order to identify reliability and efficiency of such systems, this paper presents a simplified transient modeling approach for an ORC operating under variable heat input. The approach considers that response of the system to heat input variations is mainly dictated by...
Feasibility analysis and proof of concept for thermoelectric energy harvesting in mobile computers
Denker, R.; Muhtaroglu, A. (AIP Publishing, 2013-03-01)
Thermoelectric (TE) energy harvesting in compact microelectronic systems necessitates detailed upfront analysis to ensure unacceptable performance degradation is avoided. TE integration into a notebook computer is empirically investigated in this work for energy harvesting. A detailed finite element model was constructed first for thermal simulations. The model outputs were then correlated with the thermal validation results of the selected system. In parallel, a commercial TE micro-module was empirically c...
