Information handling system with a tandem fan package
A fan package of an information handling system includes a rear cooling fan, a front cooling fan, and a fan fin package. The rear cooling fan generates a first airflow. The front cooling fan generates a second airflow. The fan fin package is in physical communication with the rear cooling fan and the front cooling fan. The fan fin package includes multiple fins. Based on the first airflow and the second airflow, the fins rotate between a closed position and an open position. The fins are biased toward the closed position.
1. A fan package for an information handling system, the fan package comprising:
a rear cooling fan to generate a first airflow;
a front cooling fan to generate a second airflow; and
a fan fin package in physical communication with the rear cooling fan and the front cooling fan, the fan fin package including a plurality of fins, wherein an inlet airflow pulled within the fan package and an outlet airflow pushed from the fan package force the fins to rotate from a closed position to an open position, wherein the fins are biased toward the closed position.
2. The fan package of claim 1 , wherein the fan fin package is located in between the rear cooling fan and the front cooling fan.
3. The fan package of claim 1 , wherein the fins are in the open position in response to the first airflow, the second airflow, or a combination of the first and second airflows.
4. The fan package of claim 3 , wherein the fins direct the first airflow from the rear cooling fan to the front cooling fan while the fins are in the open position.
5. The fan package of claim 1 , wherein in response to a failure of the rear cooling fan and a failure of the front cooling fan, the fins are in the closed position.
6. The fan package of claim 1 , wherein the fins remove a swirling effect of the first airflow before the first airflow is provided to the front cooling fan.
7. The fan package of claim 1 , wherein the fan fin package prevents re-circulation of a third airflow in the information handling system when the fins are in the closed position.
8. An information handling system comprising:
a plurality of hard disk drives; and
a fan package, the fan package including:
a rear cooling fan to pull a first airflow from outside of the information handling system and across the hard disk drives;
a front cooling fan to generate a second airflow; and
a fan fin package in physical communication with the rear cooling fan and the front cooling fan, the fan fin package including a plurality of fins, the fins to rotate between a closed position and an open position based on the first airflow and the second airflow, wherein the fins are biased toward the closed position.
9. The information handling system of claim 8 , wherein the fan fin package is located in between the rear cooling fan and the front cooling fan.
10. The information handling system of claim 8 , wherein the fins are in the open position in response to the first airflow, the second airflow, or a combination of the first and second airflows.
11. The information handling system of claim 10 , wherein the fins direct the first airflow from the rear cooling fan to the front cooling fan while the fins are in the open position.
12. The information handling system of claim 8 , wherein in response to a failure of the rear cooling fan and a failure of the front cooling fan, the fins are in the closed position.
13. The information handling system of claim 8 , wherein the fins remove a swirling effect of the first airflow before the first airflow is provided to the front cooling fan.
14. The information handling system of claim 8 , wherein the fan fin package prevents re-circulation of a third airflow in the information handling system when the fins are in the closed position.
15. The information handling system of claim 8 , wherein the fan fin package enables the rear and front cooling fans to run at a lower speed to produce a specific cooling temperature, wherein the lower speed generates less vibrations within the information handling system.
16. An information handling system comprising:
a plurality of hard disk drives;
a plurality of processors; and
a fan package including:
a rear cooling fan to pull a first airflow from outside of the information handling system and across the hard disk drives;
a front cooling fan to push a second airflow out of the fan package and across the processors; and
a fan fin package in physical communication with the rear cooling fan and the front cooling fan, the fan fin package including a plurality of fins to rotate between a closed position and an open position based on the first airflow and the second airflow, wherein the fins are biased toward the closed position.
17. The information handling system of claim 16 , wherein the fan fin package is located in between the rear cooling fan and the front cooling fan.
18. The information handling system of claim 16 , wherein the fins direct the first airflow from the rear cooling fan to the front cooling fan while the fins are in the open position.
19. The information handling system of claim 16 , wherein the fins remove a swirling effect of the first airflow before the first airflow is provided to the front cooling fan.
20. The information handling system of claim 16 , wherein the fan fin package prevents re-circulation of a third airflow in the information handling system when the fins are in the closed position.
