Abstract

The disclosed embodiments related to a component for use in a portable electronic device. The component includes a wall of the portable electronic device, containing an intake zone that includes a set of intake vents. The wall also includes an exhaust zone containing a set of exhaust vents.

First claim

What is claimed is:

1. A portable electronic device, comprising:
a bottom case having a wall characterized by:
an intake zone comprising a set of intake vents defined in the wall of the bottom case,
an exhaust zone comprising a set of exhaust vents defined in the wall of the bottom case; and

a housing comprising a clutch barrel rotatable with respect to the bottom case and positioned proximate the intake zone and exhaust zone to define an intake flow path to the set of intake vents and an exhaust flow path from the set of exhaust vents, wherein the clutch barrel at least partially extends about a hinge rotatably coupling the housing with the bottom case, and wherein the clutch barrel is maintained spatially separated from the set of intake vents and the set of exhaust vents during rotation of the housing about the hinge.

2. The portable electronic device of claim 1 , further comprising a top case coupled with the bottom case, wherein the hinge provides a first positional alignment of the housing with the bottom case in which the housing is in closed contact with the top case.

3. The portable electronic device of claim 2 , wherein, when in the first positional alignment, the clutch barrel defines a single intake flow path and a single exhaust flow path.

4. The portable electronic device of claim 3 , wherein the single intake flow path and the single exhaust flow path extend towards a base of the bottom case.

5. The portable electronic device of claim 1 , further comprising a top case, wherein the hinge provides a second positional alignment of the housing with the bottom case in which the housing is separated from the top case.

6. The portable electronic device of claim 5 , wherein, when in the second positional alignment, the clutch barrel defines a plurality of intake flow paths and a plurality of exhaust flow paths.

7. The portable electronic device of claim 6 , wherein the plurality of intake flow paths include a first fluid path extending along the clutch barrel and the top case, and a second fluid path extending along the clutch barrel and the bottom case.

8. The portable electronic device of claim 6 , wherein the housing incorporates a display, and wherein the exhaust flow paths direct fluid flow to avoid the display.

9. The portable electronic device of claim 6 , wherein the plurality of exhaust flow paths include a first fluid path extending along the clutch barrel and the top case, and a second fluid path extending along the clutch barrel and the bottom case.

10. The portable electronic device of claim 1 , wherein the portable electronic device comprises a laptop computer.

11. A portable electronic device, comprising:
a top case;
a bottom case coupled with the top case to define an internal volume, wherein the bottom case includes a wall characterized by:
an intake zone comprising a set of intake vents defined in the wall of the bottom case,
an exhaust zone comprising a set of exhaust vents defined in the wall of the bottom case; and

a housing comprising a clutch barrel rotatable with respect to the bottom case and positioned proximate the intake zone and exhaust zone to define an intake flow path to the set of intake vents and an exhaust flow path from the set of exhaust vents, wherein the clutch barrel at least partially extends about a hinge rotatably coupling the housing with the bottom case, wherein the hinge provides a first positional alignment of the housing with the bottom case in which the housing is in closed contact with the top case, and wherein, when in the first positional alignment, the clutch barrel defines a single intake flow path and a single exhaust flow path.

12. The portable electronic device of claim 11 , wherein the portable electronic device comprises two exhaust zones, and wherein the intake zone is located between the two exhaust zones.

13. The portable electronic device of claim 12 , further comprising a heat generating component positioned within the internal volume, the heat generating component thermally coupled with a heat distribution assembly configured to distribute heat from the heat generating component towards the two exhaust zones.

14. The portable electronic device of claim 13 , wherein the distributed heat is expressed from the two exhaust zones and directed along the clutch barrel past the bottom case.

15. The portable electronic device of claim 14 , wherein the distributed heat is further directed along the clutch barrel past the top case.

16. The portable electronic device of claim 12 , further comprising two fans, each fan positioned to provide an outlet flow towards a respective exhaust zone.

17. A portable electronic device, comprising:
a housing comprising a rotatable display and a clutch barrel defining airflow paths from the portable electronic device;
a top case; and
a bottom case coupled with the top case to define an internal volume housing a heat generating component, wherein the bottom case includes a wall characterized by:
an intake zone comprising a set of intake vents defined in the wall of the bottom case and angled to direct an intake airflow along the clutch barrel towards the heat generating component, and
an exhaust zone comprising a set of exhaust vents defined in the wall of the bottom case and configured at an angle different from the set of intake vents.

18. The portable electronic device of claim 17 , wherein the clutch barrel defines an exhaust airflow path from the exhaust zone directed away from the rotatable display.
