System and method for thermal management and electromagnetic interference management
A data processing device includes an internal volume for housing electromagnetic interference emitting devices. The data processing device further includes a first electromagnetic radiation absorbing vent. The data processing device further includes a second electromagnetic radiation absorbing vent. The first electromagnetic radiation absorbing vent and the second electromagnetic radiation absorbing vent delineate a gas flow path through the internal volume.
1. A data processing device, comprising:
an internal volume for housing electromagnetic interference (EMI) emitting devices, wherein the EMI emitting devices comprise hardware devices that emit EMI; and
two electromagnetic radiation (EMR) absorbing vents that delineate a gas flow path through the internal volume,
wherein a first EMR absorbing vent of the EMR absorbing vents comprises a first plurality of gas flow paths,
wherein the first plurality of gas flow paths comprises hollow portions of a body that comprises an EMR lossy material,
wherein the first plurality of gas flow paths is delineated by a gas flow pattern on a surface of the body,
wherein a second EMR absorbing vent of the EMR absorbing vents comprises a second plurality of gas flow paths,
wherein the second plurality of gas flow paths is delineated by a non-linear gas flow pattern on a surface of a second body that comprises a second EMR lossy material, and
wherein the lossy material has a real permittivity of a range between 1 and 50 for EMI in a frequency range at least 0.7 and less than 2 gigahertz.
2. The data processing device of claim 1 , wherein the internal volume is adapted to suppress EMI transmission from within the internal volume to an ambient environment.
3. The data processing device of claim 1 , wherein at least one of the two EMR absorbing vents comprises a reversibly deformable material.
4. The data processing device of claim 1 , wherein the EMR lossy material has an electrical loss tangent of greater than 0.1.
5. The data processing device of claim 1 , wherein the EMR lossy material has a magnetic loss tangent of greater than 0.5.
6. The data processing device of claim 1 , wherein the non-linear gas flow pattern is asymmetric.
7. The data processing device of claim 1 , wherein the non-linear gas flow pattern corresponds to a shadow of a gas flow control device hosted by the data processing device, wherein the gas flow control device is a fan disposed outside of the internal volume.
