Effective thermal conductivity in thermoelectric materials

Thermoelectric generators (TEGs) are solid state heat engines that generate electricity from a temperature gradient. Optimizing these devices for maximum power production can be difficult due to the many heat transport mechanisms occurring simultaneously within the TEG. In this paper, we develop a model for heat transport in thermoelectric materials in which an " effective thermal conductivity ...

High Frequency Circuit Materials With Increased Thermal Conductivity

Thermal management has always been a major concern in the design of high frequency, high power electronic devices. Historically, in most power amplifier designs, the vast majority of the power dissipated is from the high power field effect transistors (FET) themselves. In these cases, the high power dissipation requires direct attachment of the FETs to a finned heat sink, or conduction through ...

TOPOLOGY OPTIMIZATION OF COMPOSITE MATERIALS WITH OPTIMAL STIFFNESS AND THERMAL CONDUCTIVITY

This paper presents the bidirectional evolutionary structural optimization (BESO) method for the design of two-phase composite materials with optimal properties of stiffness and thermal conductivity. The composite material is modelled by microstructures in a periodical base cell (PBC). The homogenization method is used to derive the effective bulk modulus and thermal conductivity. BESO procedur...
