Apparatus, system, and method for venting a chassis
View Patent ↗An apparatus, system, and method are provided for venting an enclosure, such as a chassis housing electronic equipment. The method includes receiving, at least one air directing surface, airflow moving in a first direction, the at least one air directing surface being disposed externally from the chassis at a predetermined placement relative to the at least one ventilation surface in a path of the airflow. The at least one air directing surface has a configuration to alter the direction of the airflow between the air directing surface and the at least one ventilation surface. The method also includes redirecting the airflow between the at least one air directing surface and the at least one ventilation surface to at least a second direction using the air directing surface. The predetermined placement and configuration of the at least one air directing surface determine the second direction in which the airflow is discharged, and the second direction is either towards or away from the at least one ventilation surface. Also in the receiving, the airflow is received at least one air directing surface of a bracket configured to attach the chassis to a mounting structure.
1. A method of ventilating a chassis having at least one ventilation surface with at least one aperture formed therein to permit air to pass therethrough, the method comprising:
receiving, at least one first air directing surface, airflow moving in a first direction, the at least one first air directing surface being disposed externally from the chassis at a predetermined placement relative to the at least one ventilation surface in a path of the airflow, the at least one first air directing surface having a configuration to alter the direction of the airflow;
redirecting the airflow between the at least one first air directing surface and the at least one ventilation surface to at least a second direction using the at least one first air directing surface;
wherein the predetermined placement and configuration of the at least one first air directing surface determine the second direction in which the airflow is discharged, and the second direction is either towards or away from the at least one ventilation surface, and
wherein the at least one first air directing surface is formed by a bracket that fixedly attaches to a surface of the chassis and to a surface of a mounting structure such that the chassis is supported by the mounting structure by way of the bracket, each of the bracket and the mounting structure being external to the chassis.
2. The method of claim 1 , wherein the at least one first air directing surface also is formed by a surface of the mounting structure.
3. The method of claim 1 , wherein in the redirecting, the airflow is redirected by at least one surface of the mounting structure.
4. The method of claim 1 , further comprising further redirecting the airflow from the second direction to at least one other direction.
5. The method of claim 1 , further comprising:
further receiving, at a second air directing surface, airflow from the first air directing surface moving in the second direction, the second air directing surface being disposed externally from the chassis at another predetermined placement relative to the at least one ventilation surface; and
further redirecting the airflow in a third direction using the second air directing surface,
wherein the predetermined placement and configuration of the second air directing surface determine the third direction in which the airflow is discharged, and the third direction is either towards or away from the at least one ventilation surface.
6. The method of claim 5 , wherein the second air directing surface is at least one surface of a baffle.
7. The method of claim 5 , wherein the second air directing surface is at least one surface of the mounting structure.
8. The method of claim 1 , wherein the first direction is substantially parallel to the ventilation surface.
9. The method of claim 1 , wherein receiving includes receiving the airflow in a first direction from at least one air directing surface of a baffle.
10. The method of claim 1 , wherein the second direction is substantially perpendicular to the ventilation surface.
11. The method of claim 5 , wherein the second air directing surface is formed by another bracket configured to attach the chassis to the mounting structure.
12. The method of claim 11 , wherein the second air directing surface also includes a surface of the mounting structure attached to the other bracket.
13. The method of claim 5 , wherein in redirecting the airflow between the first air directing surface and the second air directing surface, the airflow passes at least partially through the chassis.
14. The method of claim 5 , wherein the third direction is substantially perpendicular to the second direction.
15. The method of claim 1 , wherein the first direction is substantially perpendicular to the second direction.
16. The method of claim 5 , wherein the second air directing surface receives the redirected airflow passing through another ventilation surface disposed proximate to the second air directing surface.
17. The method of claim 16 , wherein the second air directing surface is disposed at an exit end of the chassis opposite from the ventilation surface disposed at an inlet end of the chassis.
18. The method of claim 1 , further including generating the airflow with at least one fan disposed within the chassis.
19. The method of claim 1 , further including generating the airflow with at least one fan disposed externally from the chassis.
20. The method of claim 5 , wherein the first, second, and third directions form a generally serpentine path.
