微机机箱主动防尘设计研究

A Study of Active Dust-Proof Design of the Microcomputer Box

本文首先对现代城市空气中颗粒污染的特性进行了分析，就传统机箱设计中不利于防尘的弊端进行了研究，并对主动防尘－－－微正压防尘－－－原理、优点及必要性作了分析。

s: Characteristics of particle contamination in the air of cities are analyzed and the drawbacks of dust-proof design of conventional microcomputer boxes are then studied. For easy implementation of the active dust-proof technique, a detailed discussion is made on the principle, advantage and necessity of this design.
