电子器件的散热技术及其计算方法

Heat Dissipation Technology for Electronic Devices and Its Calculation Methods

介绍了电子器件散热中常用的部件,包括热管、散热器、微型风扇等,以及为满足不断提高的热流密度而出现的新型散热部件,如振荡热管、微槽道散热器等。同时,结合电子器件散热特点,总结了散热计算的一些方法。这些计算方法是进行产品热设计和热分析的重要工具。

Several components currently used for electronic devices heat dissipation have been presented, including heat pipe, heat exchanger and miniature fan, etc.. New components which are intended to meet the increasingly high heat flux, such as Pulsating Heat Pipe（PHP）, heat exchanger with microchannel, etc., have been discussed. Furthermore, on the basis of the specialties of heat dissipation for electronic devices, cal-culation methods are summarized. These calculation methods provide useful tools for thermal design and thermal analysis of related products.
