Thermoelectric (TE) module integration into a notebook computer is experimentally investigated in this thesis for its energy harvesting opportunities. A detailed Finite Element (FE) 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 experimentally characterized to quantify maximum power generation opportunity from the combined system and component data set. Next, suitable “warm spots” were identified within the mobile computer to extract TE power with minimum or no notable impact to system performance, as measured by thermal changes in the system, in order to avoid unacceptable performance degradation. The prediction was validated by integrating a TE micro-module to the mobile system under test. Measured TE power generation power density in the carefully selected region of the heat pipe was around 1.26 mW/cm3 with high CPU load. The generated power scales down with lower CPU activity and scales up in proportion to the utilized opportunistic space within the system. The technical feasibility of TE energy harvesting in mobile computers was hence experimentally shown for the first time in this thesis.

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...
A self-powered integrated interface circuit for low power piezoelectric energy harvesters Chamanian, S.; Zorlu, O.; Külah, Haluk; Muhtaroglu, A. (2013-12-18) This paper presents a CMOS integrated interface circuit for piezoelectric energy harvesters (PEH). A fully self-powered circuit, based on Synchronous Electric Charge extraction (SECE) technique, is implemented for non-resonant piezoelectric harvesters generating low power, in 10s to 100s mu W range. The circuit is realized in standard 180 nm UMC CMOS technology. A switch control circuit is designed and optimized to extract maximum power independently from excitation changes of the PEH. The total power loss ...
Implementation of a risc microcontroller using fpga Gümüş, Raşit; Güran, Hasan; Department of Electrical and Electronics Engineering (2005) In this thesis a microcontroller core is developed in an FPGA. Its instruction set is compatible with the microcontroller PIC16XX series by Microchip Technology. The microcontroller employs a RISC architecture with separate busses for instructions and data. Our goal in this research is to implement and evaluate the design in the FPGA. Increasing performance and gate capacity of recent FPGA devices permits complex logic systems to be implemented on a single programmable device. Such a growing complexity dema...
CHARACTERIZATION OF SPECIFIC HEAT AND MECHANICAL PROPERTIES FOR GRANULAR HEAT STORAGE MATERIALS Baker, Derek Keıth; Johnson, Evan Fair(2018-12-31) The GUNAM-ODAK research group is developing Thermal Energy Storage (TES) technologies for Concentrated Solar Power systems. Focus is on solid-particle (granular) TES materials such as silica sand due to their high melting temperatures and low costs. In the proposed work, the experimental equipment needed to characterize some of the most important properties of TES materials will be constructed, with the goal of characterizing new materials and providing accurate inputs for numerical modeling. Specifically, ...
CFD analysis of a notebook computer thermal management solution Yalçın, Fidan Seza; Tarı, İlker; Department of Mechanical Engineering (2008) In this study, the thermal management system of a notebook computer is investigated by using a commercial finite volume Computational Fluid Dynamics (CFD) software. After taking the computer apart, all dimensions are measured and all major components are modeled as accurately as possible. Heat dissipation values and necessary characteristics of the components are obtained from the manufacturer's specifications. The different heat dissipation paths that are utilized in the design are investigated. Two active...
