Abstract

A computing system includes a chassis having an airflow entrance and an airflow exhaust, a duct structure disposed in the chassis, and a redirection mechanism located on a wall of the duct structure and extending through a cutout in the wall of the duct structure. In the computing system, the duct structure has a first end facing the airflow entrance and a second end facing the airflow exhaust. The redirection mechanism has a deflector having an inlet airfoil extending away from the duct structure towards the airflow entrance and at least one exhaust airfoil extending into the duct structure.

First claim

The invention claimed is:

1. A computing system, comprising:
a chassis having an airflow entrance and an airflow exhaust;
a duct structure disposed in the chassis, the duct structure having a first end facing the airflow entrance and a second end facing the airflow exhaust; and
a redirection mechanism located on a wall of the duct structure and extending through a cutout in the wall of the duct structure, the redirection mechanism comprising a deflector having an inlet airfoil extending away from the duct structure towards the airflow entrance and at least one exhaust airfoil extending into the duct structure.

2. The system of claim 1 , wherein the deflector is attached to the duct structure in a fixed position.

3. The system of claim 1 , wherein the deflector further comprises:
a hinge rotatably attaching the deflector to the duct structure; and
a spring that biases the deflector towards a first position.

4. The system of claim 1 , further comprising at least one additional redirection mechanism extending through the wall of the duct structure.

5. The system of claim 1 , further comprising:
at least one additional duct structure disposed in the chassis, the additional duct structure having a first end facing the airflow entrance and a second end facing the airflow exhaust; and
an additional redirection mechanism located on a wall of the additional duct structure and extending through a cutout in the wall of the additional duct structure, the redirection mechanism comprising a deflector having an inlet airfoil extending away from the additional duct structure towards the airflow entrance and at least one exhaust airfoil extending into the additional duct structure.

6. The system of claim 1 , further comprising at least one airfoil support structure configured for preventing the inlet foil from fully moving to a closed position with respect to the wall.

7. The system of claim 1 , wherein the inlet airfoil maintains a position between the open position and the closed position, based on a rate of airflow from the airflow entrance to the airflow exhaust.

8. The system of claim 1 , wherein the deflector further comprises at least one additional exhaust airfoil of a different length than the exhaust foil.

9. The system of claim 1 , wherein the deflector further comprises at least one additional exhaust airfoil attached at a different angle than the exhaust foil.

10. The system of claim 1 , when the duct structure is disposed in the chassis to surround two or more rows of computing modules, and wherein the cutout is located adjacent to a space between two of the rows of computing modules.

11. The system of claim 1 , wherein the deflector comprises a flexible material.
