A heat pipe is a closed system that contains a saturated fluid. When heat is dissipated in one region of the heat pipe, liquid in that area boils or evaporates, which produces vapor that moves to another area in the heat pipe where it condenses. The condensed liquid then returns to its starting point to transport energy from the heat input region(s) to the heat output … [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...]
Thermal Penalties of Bandwidth Enhancements for Li-Fi Communication
The rapid increase of device connectivity, coupled with constantly growing data transmission rates, increases the demand for new communication channels. Illumination systems employing Light Emitting Diodes (LEDs) have the potential to fulfill this demand. LEDs are versatile components that are used as a light source in a vast number of products: indoor and outdoor lighting, … [Read more...]
Summary of the IEEE ITherm 2022 Conference
The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the Sheraton Hotel & Marina in San Diego, CA, May 31 – June 3, 2022. This was the 21st ITherm, which was first held in 1988. The conference was historically held every other year until 2016 when it switched to an annual schedule. ITherm 2022 was sponsored by … [Read more...]
Thermal Modeling of a Silicon Germanium (SiGe) Radio Frequency Integrated Circuit (RFIC) for Wireless Communications
The creation, transport and storage of digital information are growing at rates of 40% to 50% annually, with video, mobile broadband, and machine-to-machine communication being the main drivers.
