本文就电子设备的热设计中,关于新型、高效的传热元件-热管的应用问题,从它的结构特性、近似计算和热管的优缺点等,结合电子设备的具体情况予以介绍。同时,根据我们制作的几种样管(包括玻璃热管、扁平热管、圆形热管)的实测情况作了一些粗浅的分析。最后,就目前国内外电子设备用的部分热管作了介绍。 In this paper, the thermal design of electronic equipment, the new and efficient heat transfer element - the application of heat pipe, from its structural characteristics, approximate calculation and the advantages and disadvantages of the heat pipe, combined with the specific circumstances of electronic equipment are introduced. At the same time, we make some superficial analysis based on the actual situation of several sample tubes (including glass heat pipe, flat heat pipe and circular heat pipe) we made. At last, some current heat pipes used in electronic equipment are introduced.
