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.
高功率LED发光效率进展飞速，相对也带来更严苛的散热挑战，由于从晶片、封装、基板至系统各层级环环相扣，因此须逐一克服难关才能真正符合市场的散热要求，其中FR4基板将為大势所趋；系统可透过关键元件改善散热难题...
This article describes the procedure for calculating air density given the temperature, dewpoint and pressure or temperature, pressure and relative humidity.
电子设备散热系统的设计对设备的可靠性有重要影响，风冷散热相对成本较低，而且效率比较高，因此风冷散热是室内电子设备散热的常用手段，风扇的选型关系到设备的可靠性及产品总成本。对于没有经验的工程师来说，选择一款风扇可能显得无从下手，似乎没有任何可供衡量的标准。本文将介绍风扇选型的一般步骤：根据系统的发热量计算散热所需的风量，然后根据系统的特性选择合适的风扇。另外，还介绍了风扇转速对系统的影响，风扇效率的定义，以及设备设计安装时需注意的问题。
