By: Marta Rencz, Andras Poppe, and Genevieve Martin The 29th issue of the THERMINIC (Thermal investigations of ICs and Systems) workshops was held on 27-29 September 2023 in Budapest, Hungary at the Budapest Marriott Hotel. Over 110 participants enjoyed the high quality presentations from 17 countries. About half of the participants came from the industry, half from the … [Read more...]
Summary of the IEEE ITherm 2023 Conference
The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the JW Marriott Grande Lakes, Orlando, FL, May 30 – June 2, 2023. This was the 22nd 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 2023 was sponsored by the … [Read more...]
Calculation Corner: Properties of Humid Air
INTRODUCTION Long time readers may recall that one answer to the question of how humidity changes the thermal conductivity of air is “Nothing to worry about” [1]. Generally, the effect of humidity on air properties is small enough that it can be neglected. However, at high ambient temperatures and low pressure, humidity effects may need to be addressed in applications such as … [Read more...]
Calculation Corner: A Simple Method for Estimating Radiation Heat Transfer
This article describes a semi-empirical equation that can be used to assess radiation heat transfer in terms of an effective convection coefficient. The effective convection coefficient due to radiation is shown to be: Where temperatures are in °C and ε is the emissivity of the radiating surface. This equation is accurate to within ~10% over a temperature range of 0 - … [Read more...]
Utilizing Boyd Coolant Distribution Units (CDUs)
Introduction Let's begin with two images that may be familiar, but will provide a very good illustration to help us frame the current market trend and why liquid cooling is on the rise. The two charts in Figure 1 show actual CPU and GPU power consumption over the years, and Figure 2 shows an overall trend in chip power. As we can see here at this point, in 2023 at 700 … [Read more...]
