The framework for this paper is the growing concern about the worldwide increasing energy consumption of telecommunications systems and data centers, and particularly the contribution of the thermal management system.
Interest has been growing in integrated circuits for controlling the speed of cooling fans in personal computers and other electronic equipment. Compact electrical fans are cheap and have been used for cooling electronic equipment for more than half a century. However, in recent years, the technology of using these fans has evolved significantly. This article will describe how and why this evolution has taken place and will suggest some useful approaches for the designer.
Designing a forced convection system for a chassis or cabinet is a complicated task which must be done correctly to ensure the performance and reliability of the enclosed electronics. There are many thermal, mechanical, and electrical effects to consider when selecting a fan.
Most Electronics Packaging Engineers and Analysis Specialists have access to a wide range of high quality analysis tools. While a few computer programs use analytical methods, the majority are based on numerical analysis techniques.
