Abstract

An information handling system may include a chassis configured to house components of the information handling system and an air mover assembly comprising an enclosure, an air mover within the enclosure configured to drive airflow to cool one or more components of the information handling system, and a sensor within a path of the airflow and configured to detect a presence of matter harmful to one or more components of the information handling system.

Claims (33)

1. An information handling system comprising:

a chassis configured to house components of the information handling system; and

an air mover assembly comprising:

an enclosure;

an air mover within the enclosure configured to drive airflow to cool one or more components of the information handling system;

a printed circuit board fastened to the enclosure, positioned within the airflow driven by the air mover, and communicatively coupled to the air mover, wherein components mounted on the printed circuit board include:

components for controlling operation of the air mover; and

a harmful matter sensor configured to detect a presence of matter harmful to one or more components of the information handling system.

2. The information handling system of claim 1 , wherein the harmful matter sensor comprises a particle sensor configured to detect the presence of particulate matter harmful to one or more components of the information handling system.

3. The information handling system of claim 1 , wherein the harmful matter sensor comprises a gas sensor configured to detect the presence of a gas harmful to one or more components of the information handling system.

4. The information handling system of claim 1 , wherein the printed circuit board includes first and second substantially planar major surfaces and wherein the printed circuit board is affixed to the housing with the first and second substantially planar surfaces oriented in parallel with the air flow driven by the air mover.

5. The information handling system of claim 1 , wherein the air mover assembly is configured to be readily removable from the chassis.

6. An air mover assembly comprising:

an enclosure;

an air mover within the enclosure configured to drive airflow to cool one or more components of an information handling system comprising the air mover assembly;

a printed circuit board affixed to the enclosure, positioned within the airflow driven by the air mover, and communicatively coupled to the air mover, wherein components mounted on the printed circuit board include:

components for controlling operation of the air mover; and

a harmful matter sensor configured to detect a presence of matter harmful to one or more components of the information handling system.

7. The air mover assembly of claim 6 , wherein the harmful matter sensor comprises a particle sensor configured to detect the presence of particulate matter harmful to one or more components of the information handling system.

8. The air mover assembly of claim 6 , wherein the harmful matter sensor comprises a gas sensor configured to detect the presence of a gas harmful to one or more components of the information handling system.

9. The air mover assembly of claim 6 , wherein:

the air mover assembly further comprises a printed circuit board communicatively coupled to the air mover and comprising components for control or monitoring of operation of the air mover; and

the harmful matter sensor is mounted on the printed circuit board.

10. The air mover assembly of claim 6 , wherein the air mover module is configured to be readily removable from the chassis.

11. A method comprising:

housing an air mover within an enclosure of an air mover assembly, wherein the air mover is configured to drive airflow to cool one or more components of an information handling system comprising the air mover assembly; and

fastening, to the enclosure, a printed circuit board positioned within the airflow driven by the air mover, wherein components mounted on the printed circuit board include:

components for controlling operation of the air mover; and

a harmful matter sensor configured to detect a presence of matter harmful to one or more components of the information handling system.

12. The method of claim 11 , wherein the harmful matter sensor comprises a particle sensor configured to detect the presence of particulate matter harmful to one or more components of the information handling system.

13. The method of claim 11 , wherein the harmful matter sensor comprises a gas sensor configured to detect the presence of a gas harmful to one or more components of the information handling system.

14. The method of claim 11 , wherein the printed circuit board includes first and second substantially planar major surfaces and wherein the printed circuit board is affixed to the housing with the first and second substantially planar surfaces oriented in parallel with the air flow driven by the air mover.

15. The method of claim 11 , wherein the air mover assembly is configured to be readily removable from the chassis.
