Abstract

Apparatus and method for cooling a display unit includes having a first set of one or more openings to allow pressured air to enter a display unit housing and a second set of one or more openings to allow the air to exit. The pressured air is generated by an air movement device. The air movement device may be internal or external to the display unit housing.

a first enclosure, the first enclosure including an air movement device; and

a second enclosure coupled to the first enclosure, the second enclosure including heat-generating electronic components associated with a display screen, the second enclosure further including a first opening to receive airflow generated by the air movement device, the airflow is to cool the heat-generating electronic components in the second enclosure.

13. The apparatus of claim 12, wherein the second enclosure further includes a second opening to release the air received at the first opening.

14. The apparatus of claim 13, wherein the second opening is positioned away from the first opening to enable the airflow to cool more heat-generating electronic components.

15. The apparatus of claim 14, wherein the airflow flows from the first opening to the second opening behind the display screen.

16. The apparatus of claim 12, wherein the display screen is a liquid crystal display (LCD).

17. The apparatus of claim 12, wherein the airflow generated by the air movement device further cools heat-generating electronic components in the first enclosure.

18. An apparatus, comprising:

a housing, the housing including an air movement device, a first opening, a second opening, and electronic components associated with a display screen, the air movement device is to cause airflow to enter the housing through the first opening and to flow behind the display screen toward the second opening.

19. The apparatus of claim 18, wherein the housing further includes a processor and electronic components associated with the processor, the processor coupled to the display screen, wherein the airflow is to cool the electronic components associated with the display screen and the electronic components associated with the processor.

20. The apparatus of claim 18, wherein the air movement device is a fan, and the display screen is a liquid crystal display (LCD).

21. A display unit in a mobile computing device, comprising:

a display screen; and

a first set of one or more openings to receive pressured air caused by a cooling device, the air is to flow behind the display screen to a second set of one or more openings.

22. The display unit of claim 21, further comprising electronic components associated with the display screen, and wherein the pressured air is to cool the electronic components.

23. The display unit of claim 22, wherein the first set of one or more openings is positioned at a location where there is a high concentration of heat generated by the electronic components associated with the display screen.

24. The display unit of claim 22, wherein the second set of one or more openings is positioned relative to the first set of one or more openings to enable more cooling of the electronic components associated with the display screen.

25. A computer system, comprising:

a base unit, the base unit including an air movement unit to generate airflow; and

a display unit coupled to the base unit, the display unit including a display screen and a first opening, wherein the first opening is positioned close to the air movement unit to receive the airflow generated by the air movement unit.

26. The system of claim 25, wherein heat generated by electronic components associated with the display screen is cooled by the airflow received at the first opening.

27. The system of claim 25, wherein the display unit further includes a second opening to allow cross ventilation of the airflow received at the first opening.

28. The system of claim 25, wherein the base unit further includes a processor and electronic components associated with the processor, and wherein heat generated by the electronic components associated with the processor is cooled by the airflow generated by the air movement unit.

29. A method, comprising:

forcing air through a first set of one or more openings of a display unit housing into the display unit housing, the air generated by an air movement device external to the display unit housing and is to dissipate heat generated by one or more electronic components included in the display unit housing.

30. The method of claim 29, wherein the air exits the display unit housing through a second set of one or more openings.

31. The method of claim 29, wherein the display unit housing includes a display screen and electronic components associated with the display screen.
