Embodiments disclosed herein include EMI shielding to cool a computing device with one or more vents. In some embodiments, a louvered vent formed in the EMI shield of a computing device creates an air curtain between the EMI shield and a heat-generating component to cool the component, the EMI shield and the external wall. Other embodiments are described.

What is claimed is: 1. An apparatus, comprising: an electronic component capable of generating heat; an external wall; an electromagnetic interference (EMI) shield to be positioned between the external wall and the electronic component; and a louvered vent formed within the EMI shield, the louvered
What is claimed is: 1. An apparatus, comprising: an electronic component capable of generating heat; an external wall; an electromagnetic interference (EMI) shield to be positioned between the external wall and the electronic component; and a louvered vent formed within the EMI shield, the louvered vent to create an air curtain between the EMI shield and the heat generating component when air is flowing, wherein the louvered vent is positioned in relation to the heat generating component to create the air curtain to deflect at least a portion of the heat from the heat generating component from reaching the EMI shield when air is flowing. 2. The apparatus of claim 1, wherein the heat generating component is a central processing unit (CPU), chipset, or memory. 3. The apparatus of claim 1, wherein the louvered vent draws air from outside of the EMI shield into the apparatus to form the air curtain. 4. The apparatus of claim 1, wherein the louvered vent extends from an inside surface of the EMI shield into the apparatus. 5. The apparatus of claim 1, wherein the EMI shield is to provide electromagnetic interference (EMI) protection for the apparatus. 6. The apparatus of claim 1, wherein the louvered vent is formed as a squared off chamber, a curved shape, or at an angle, the angle being in an approximate range between 15 degrees and 45 degrees with respect to the EMI shield. 7. The apparatus of claim 1, wherein the louvered vent is part of a row of louvered vents positioned to create an air curtain along the EMI shield. 8. A computing device, comprising: an electronic component capable of generating heat; a chip containing the electronic component; an electromagnetic interference (EMI) shield to be positioned between an external wall of the computing device and the electronic component; and a louvered vent formed within the EMI shield to create an air curtain between the EMI shield and the heat generating component when air is flowing, wherein the louvered vent is positioned in relation to the heat generating component to create the air curtain to deflect at least a portion of the heat from the heat generating component from reaching the EMI shield when air is flowing. 9. The device of claim 8, wherein the heat generating component is a central processing unit (CPU), chipset, or memory. 10. The device of claim 8, wherein the louvered vent draws air from outside of the EMI shield into the computing device to form the air curtain when air is flowing. 11. The device of claim 8, wherein the louvered vent extends from an inside surface of the EMI shield into the computing device. 12. The device of claim 8, wherein the EMI shield is to provide electromagnetic interference (EMI) protection for the computing device. 13. The device of claim 8, wherein the louvered vent is formed as a squared off chamber, a curved shape, or at an angle, the angle being in an approximate range between 15 degrees and 45 degrees with respect to the EMI shield. 14. The device of claim 8, wherein the louvered vent is part of a row of louvered vents positioned to create an air curtain along the EMI shield when air is flowing. 15. The device of claim 8, further comprising: a battery to power the computing device. 16. The device of claim 8, wherein the computing device has one or more openings for the flow of air, which are formed in the external wall. 17. The device of claim 8, further comprising: a wired/wireless communication logic coupled to the chip.
