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.

Abstract: A computing device for inhibiting electrostatic discharge (ESD) in a computing system, the computing device including a mainboard with computing circuitry for the computing system, a tray in which the mainboard is affixed, and a composite liner for absorbing high-frequency energy and electromagnetic interference from the ESD. The composite liner includes a high-frequency energy absorption layer and an insulation layer coupled to a first surface of the high-frequency energy absorption layer. The high-frequency energy absorption layer includes a high-frequency energy absorption material, and the insulation layer includes an electrical-insulating material. A circuit board enclosure includes the composite liner and a panel with the composite liner at least partially lining an internal receiving surface of the panel. A circuit board is positioned inside the circuit board enclosure with the composite liner interposed between the circuit board and the panel to protect the electronic component from ESD.
