Figure 1: Telecom Equipment Operating EnvironmentsThere are two main reasons for doing thermal design in the telecommunication industry. The first is to ensure functionality of the equipment and system when subjected to extreme environments. The second is to ensure high dependability of the network. While doing thermal design, many challenges must be kept in mind: the … [Read more...]
A system level cooling solution for cellular phone applications
Improving thermal performance of electronic components is very challenging due to the increasing power density and decreasing module sizes. The design trade off between electrical and mechanical characteristics and the cost of manufacturing MCM products requires innovative solutions to improve device thermal performance. The primary cooling path in portable electronics serves … [Read more...]
Computer-related thermal packaging at the millenial divide
Examples of state-of-the-art thermal management solutions at the dawn of the 21st century (left to right): a TCM module, a high-density heat sink, and an ultra performance, low profile fan-sink. Thermal management has served as a key enabling technology in the development of advanced microelectronic systems and has facilitated many of the "Moore's Law" [Moore, G.E., 1975] … [Read more...]
Ten stupid things engineers do to mess up their cooling
Editor's Note: On the eve of the new millenium, the editors of ElectronicsCooling have decided to depart from our normal serious tone just this once, unless, of course, we can convince Tony to contribute another story or two for us sometime [soon!] in the next thousand years. Herewith, for your amusement and edification is a humorous, yet insightful, retrospective of famous - … [Read more...]
The history of power dissipation
Figure 1. Transistor counts on Intel processors from inception to present superimposed on Moore's prediction. In his fascinating book, "Visions," Michio Kaku [1] predicts a future driven by silicon and quantum computers. Based on the information we have today, it is intriguing to speculate how such a highly silicon-based society might function and evolve. Being a thermal … [Read more...]
