Abstract

Aspects of the invention are directed towards apparatus with cambered louvers. One or more embodiments of the invention describe a louver comprising a plurality of slats arranged in a vertical direction or a horizontal direction; and each of the slats in the louver comprise a leading edge, a trailing edge opposite to the leading edge, and a chord line connecting the leading edge with the trailing edge. Further, each of the slats in the louver has a cambered profile, wherein the cambered profile includes a camber distance varying in the range of about 20%-30% from the leading edge and a camber height varying in the range of about 5%-15% of a total camber height.

First claim

What is claimed is:

1. A louver comprising:
a plurality of slats arranged in a vertical direction or a horizontal direction;
each of the slats in the louver comprise a leading edge, a trailing edge opposite to the leading edge, a chord line connecting the leading edge with the trailing edge; and
each of the slats in the louver has a cambered profile, wherein the cambered profile includes a camber distance varying in the range of about 20%-25% from the leading edge and a camber height located at the camber distance, the camber height varying in the range of about 5%-15% of a total length of the cambered profile.

2. The louver of claim 1 , wherein the camber distance is configured at about 20% from the leading edge and the camber height is configured at about 10% of the total length of the cambered profile.

3. The louver of claim 1 , wherein the camber distance is configured at about 20% from the leading edge and the camber height is configured at about 5% of the total length of the cambered profile.

4. The louver of claim 1 , wherein the camber distance is configured at about 20% from the leading edge and the camber height is configured at about 15% of the total length of the cambered profile.

5. The louver of claim 1 , wherein the camber distance is configured at about 25% from the leading edge and the camber height is configured at about 10% of the total length of the cambered profile.

6. The louver of claim 1 , wherein the camber distance is configured at about 25% from the leading edge and the camber height is configured at about 5% of the total length of the cambered profile.

7. The louver of claim 1 , wherein the camber distance is configured at about 25% from the leading edge and the camber height is configured at about 15% of the total length of the cambered profile.

8. The louver of claim 1 , wherein each of the slat is positioned with respect to a setting angle, wherein the setting angle depends on the camber distance and the camber height.

9. The louver of claim 8 , wherein the setting angle varies between about 45 degrees and about 65 degrees.

10. The louver of claim 1 , wherein the louver is configured to fit on at least one side of an air-conditioner unit.

11. The louver of claim 1 , wherein there is a predetermined spacing between each of the plurality of slats in the louver.

12. The louver of claim 1 , wherein the cambered profile is configured to improve performance of an outdoor unit.

13. The louver of claim 1 , wherein the cambered profile is configured to improve energy efficient ratio of an outdoor unit.

14. The louver of claim 1 , wherein the cambered profile is configured to reduce differential pressure across an outdoor unit.
