Abstract

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.

First claim

What is claimed is:

1 . A data processing device, comprising:
an internal volume for housing electromagnetic interference (EMI) emitting devices; and two electromagnetic radiation (EMR) absorbing vents that delineate a gas flow path through the internal volume.

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 3 , wherein the at least one of the two EMR absorbing vents comprises an EMR lossy material.

5 . The data processing device of claim 4 , wherein the EMR lossy material has an electrical loss tangent of greater than 0.1.

6 . The data processing device of claim 4 , wherein the EMR lossy material has a magnetic loss tangent of greater than 0.5.

7 . The data processing device of claim 1 , wherein a first EMR absorbing vent of the EMR absorbing vents comprises a plurality of gas flow paths.

8 . The data processing device of claim 7 , wherein the plurality of gas flow paths comprises hollow portions of a body that comprises an EMR lossy material.

9 . The data processing device of claim 8 . wherein the plurality of gas flow paths is delineated by a gas flow pattern on a surface of the body.

10 . The data processing device of claim 7 , wherein a second EMR absorbing vent of the EMR absorbing vents comprises a second plurality of gas flow paths.

11 . The data processing device of claim 10 , 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.

12 . The data processing device of claim 11 , wherein the non-linear gas flow pattern is asymmetric.

13 . The data processing device of claim 11 , wherein the non-linear gas flow pattern corresponds to a shadow of a gas flow control device hosted by the data processing device.

14 . The data processing device of claim 13 , wherein the gas flow control device is a fan disposed outside of the internal volume.

15 . A method for managing a data processing device, comprising:
monitoring a thermal state of an electromagnetic interference (EMI) emitting device disposed in an EMI suppressed internal volume of the data processing device; and managing the thermal state of the EMI emitting device based on the monitoring by modulating a rate of gas flow that:
traverses through the EMI suppressed internal volume, and
is proximate to the EMI emitting device,
wherein the EMI suppressed internal volume is delineated by two electromagnetic radiation (EMR) absorbing vents.

16 . The method of claim 15 , wherein modulating the rate of gas flow comprises:
activating a gas flow control component of the data processing device to modulate the gas flow.

17 . The method of claim 16 , wherein the gas flow control component is disposed outside of the EMI suppressed internal volume and directs a second gas flow that is outside of the EMI suppressed internal volume through one of the two EMR absorbing vents to generate the gas flow.

18 . A non-transitory computer readable medium storing computer instructions which, when executed, cause a method for managing a data processing device to be performed, the method comprising:
monitoring a thermal state of an electromagnetic interference (EMI) emitting device disposed in an EMI suppressed internal volume of the data processing device; and managing the thermal state of the EMI emitting device based on the monitoring by modulating a rate of gas flow that:
traverses through the EMI suppressed internal volume, and
is proximate to the EMI emitting device,
wherein the EMI suppressed internal volume is delineated by two electromagnetic radiation (EMR) absorbing vents.

19 . The non-transitory computer readable medium of claim 18 , wherein modulating the rate of gas flow comprises:
activating a gas flow control component of the data processing device to modulate the gas flow.

20 . The non-transitory computer readable medium of claim 19 , wherein the gas flow control component is disposed outside of the EMI suppressed internal volume and directs a second gas flow that is outside of the EMI suppressed internal volume through one of the two EMR absorbing vents to generate the gas flow.
