Abstract

A system for controlling turbulence of fluid flowing past a window includes an imaging device compartment defining an interior and an exterior separated by a window, wherein the window encloses at least a portion of the interior, wherein the exterior includes at least one turbulator on a side upstream of the window positioned to induce turbulence over the entirety of a boundary layer of the fluid flowing past the window for even heat transfer between the fluid and the window.

First claim

What is claimed is:

1. A system for controlling turbulence of fluid flowing past a window comprising:
an imaging device compartment defining an interior and an exterior separated by a downward facing window, wherein the downward facing window encloses at least a portion of the interior, and wherein the window is flush with the exterior surface of the compartment; and
an imaging device within the interior of the compartment;
wherein the exterior includes at least one turbulator on a side upstream of the downward facing window positioned to induce turbulence over the entirety of a boundary layer of the fluid flowing past the downward facing window for even heat transfer between the fluid and the downward facing window.

2. The system of claim 1 , wherein the downward facing window includes a material transparent to visible light.

3. The system of claim 1 , wherein the turbulator protrudes from an exterior surface of the compartment.

4. The system of claim 1 , wherein the turbulator includes a rounded surface.

5. The system of claim 1 , wherein the turbulator includes at least one sharp edge.

6. The system of claim 1 , wherein the turbulator includes a semi-cylindrical or triangular cross section.

7. The system of claim 1 , wherein the turbulator includes an array of separate turbulator elements.

8. The system of claim 7 , wherein the array includes multiple rows of individual turbulators elements wherein the individual turbulators elements of each row are staggered with respect to individual turbulators elements an adjacent row.

9. The system of claim 7 , wherein the array includes individual turbulators elements of varying shapes.

10. The system of claim 7 , wherein the array includes individual turbulators elements protruding from the surface at different heights.

11. The system of claim 1 , wherein the exterior surface of the compartment is free of turbulators downstream of the downward facing window.

12. The system of claim 1 , wherein the exterior surface of the compartment is free of turbulators at portions lateral to the downward facing window.

13. The system of claim 1 , wherein the compartment is attached to a vehicle by a structural member.

14. The system of claim 1 , wherein the compartment is a portion of a vehicle.

15. The system of claim 1 , wherein the vehicle is an airplane.
