Abstract
An air duct formed from an electromagnetic wave absorber in the form of a sheet is disclosed. The sheet can be bent into a duct or scored, and folded at the score lines to bring the ends of the sheet into proximity. The ends can then be joined by adhesive, welding, or mechanical fasters. The air ducts disclosed herein provide dual functions of providing ventilation for electronic components in an electronic module, while at the same time, reducing electromagnetic interference (EMI). One or more air ducts, of the same or different dimensions, shapes, volumes can be combined with electronic modules, such as a server, to provide both ventilation and EMI suppression to various components within the electronic module.
