大热流密度电子设备的散热方法

Cooling Measures of High Flux Electronic Equipment

随着当代电子技术的高速发展,电子产品的热流密度急剧升高,过高的温度对电子设备正常工作的影响也越来越严重,大热流密度对电子设备的冷却技术提出了更高的要求。文中针对大热流密度电子设备的散热方法,重点介绍了强迫空气冷却、热管、微槽道等现有的散热方法的工作原理、应用方式以及应用场合,并结合相关文献简要介绍了气体喷射冷却、喷雾冷却和热电制冷等新型散热方法在大热流密度电子设备中的应用发展状况。

With the fast development of the electronic technology, the flux of electronic products becomes higher and higher. And the effect of high temperature on normal work of the electronic equipment is becoming more and more serious. Higher requirements for cooling technology for the electronic equipment are necessary due to high heat flux. This paper introduces in detail the operation principle and applications of some high per- formance cooling measures such as forced air cooling, heat pipe and micro channel cooling. Combined with the related literature, this paper also briefly introduces the application of new cooling methods such as the gas jet cooling, spray cooling and thermoelectric refrigeration to electronic equipment with high heat flux.
