Abstract
An air duct is provided for ventilating an electronic device having a processor. The air duct comprises one or more walls that have an irregular surface and that further have a layer of conductive material applied to the irregular surface. Further embodiments of the invention include electronic device enclosures and electronic devices having an air duct featuring an irregular interior surface and having conductive material applied to the irregular surface.
Claims18
An air duct for ventilating an electronic device having a processor and for attenuating a signal, comprising:
- one or more walls forming an air duct, the one or more walls further having an irregular interior surface, wherein the irregular interior surface comprises bumps selected from a group consisting of pyramidal bumps and spherical bumps, the irregular interior surface of the duct further being irregular with respect to the wavelength of a signal to be attenuated;
- and
- a layer of conductive material applied to the irregular surface.
An enclosure for an electronic device having a processor, the enclosure having an air duct for ventilation and for attenuation of a signal, the air duct comprising:
- one or more walls forming an air duct, the one or more walls further having an irregular interior surface, wherein the irregular interior surface comprises bumps selected from a group consisting of pyramidal bumps and spherical bumps, the irregular interior surface of the duct further being irregular with respect to the wavelength of a signal to be attenuated;
- and
- a layer of conductive material applied to the irregular surface.
