引言本文介紹一种在电子設备維护及运行时,維持均匀冷却空气流动的新方法。这个方法是在解决电子管计算机UDOFT(通用数字操作飛行訓練机)的冶却問題时提出來的。在本文里,我們只考慮那些需要用强迫通風系統來冶却的設备。裝置在框架上的設备,特别是采用插件的計算机,可以用兩种方法來冷却。一种是采用負压,或者称为吸風系統,如图1所示。利用安裝在架頂上的風扇或鼓風机,將負医加到机架的頂部。空气从机架的前面进入,經过裝在插座上的电
Introduction This article describes a new method of maintaining even cooling air flow during the maintenance and operation of electronic equipment. This method was proposed to solve the metallurgical problem of the tube computer UDOFT (Universal Digital Operation Flight Trainer). In this article, we consider only those devices that require forced ventilation systems. Devices that are mounted on a frame, especially a plug-in computer, can be cooled in two ways. One is the use of negative pressure, or aspirating system, shown in Figure 1. Use a fan or blower mounted on the top of the rack to attach the negative to the top of the rack. Air enters from the front of the rack through the electrical outlets installed in the socket
