Overview Accurate modeling of thermal networks requires that all relevant modes of heat transfer, including advection, be included. Otherwise, component temperatures may be under- or over-estimated. This article presents a method for systematically including advection in one-dimensional (1D) thermal networks, via the use of unidirectional elements in the thermal network … [Read more...]

Duocel® Metal Foam Heat Exchangers
Introduction As power-component technology advances and smaller packaging is required, thermal-management issues threaten to limit the performance of devices. As power dissipation rises, the inability to cool them may force designers to de-rate the devices’ performance by reducing current or switching speed and/or employing higher-voltage devices that are less efficient and … [Read more...]
Increased System Performance in Mobile Electronics Using High Performance Insulation-Graphite Composites
ABSTRACT Graphite foils with ultra-high spreading capacity and insulation sheets with ultra-low thermal conductivity were combined in a thermally stressed Google Pixel 3XL (Pixel) to significantly increase steady-state system performance, while maintaining safe device touch (skin) temperatures (TS ), as compared to the out-of-the-box device configuration. Four unique thermal … [Read more...]
Utilizing Laser Flash in Combination with Finite Element Modeling to Analyze Thermal Conductivity of Interfaces and Layers within Complex Structures
Abstract The utility of the laser flash thermal conductivity measurement can be greatly expanded to more complex structures by modeling laser flash results using Finite Element Models. This approach is illustrated using a test fixture with 4 heat sinks, where heat spreading is a significant factor. If traditional 1D thermal diffusion models for laser flash are used, thermal … [Read more...]
