Abstract

A computing device of an information handling system includes a computing component and a chassis for housing the computing component. The computing components may be, for example, a portion of a circuit card, hardware device, or other physical structure. The chassis includes an air exchange for receiving gases for thermal management of the computing component and a corrosion management component, physically connected directly to the air exchange, that reduces a rate of corrosion of the air exchange due to the gases.

Claims (59)

1. A computing device of an information handling system, comprising:

a computing component; and

a chassis for housing the computing component, comprising:

an air exchange for receiving gases for thermal management of the computing component, and

a corrosion management component, physically connected directly to the air exchange, adapted to reduce a rate of corrosion of the air exchange due to the gases, wherein the physical connection between the corrosion management component and the air exchange creates a potential cell between the corrosion management component and the air exchange, and wherein the potential cell reduces a chemical reactivity of the air exchange.

2. The computing device of claim 1 , wherein the air exchange comprises:

a metal sheet, and

a plurality of holes through the metal sheet adapted to enable the gases to enter the chassis,

wherein each hole of the plurality of holes through the metal sheet is circumscribed by a cut edge of the metal sheet.

3. The computing device of claim 2 , wherein the corrosion management component comprises:

a galvanic anode, wherein the galvanic anode is attached to a surface of the metal sheet facing an interior of the chassis.

4. The computing device of claim 3 , wherein the air exchange further comprises:

a viewing portal that enables a person outside of the chassis to view a portion of the galvanic anode.

5. The computing device of claim 4 , wherein the galvanic anode is adapted to change its appearance as a function of its corrosion level.

6. The computing device of claim 3 , wherein the galvanic anode is formed from a metal foam having a shape adapted to extend across at least two holes of the plurality of holes.

7. The computing device of claim 3 , wherein the galvanic anode comprises a metal foam having a shape adapted to extend across at least two holes of the plurality of holes.

8. The computing device of claim 3 , wherein the galvanic anode comprises a metal bar having a shape adapted to extend across at least two holes of the plurality of holes.

9. The computing device of claim 3 , wherein the galvanic anode comprises a metal plug having a shape adapted to be hidden from a view of a person outside of the chassis through any of the plurality of holes.

10. The computing device of claim 1 , further comprising:

an environmental manager programmed to:

monitor an environmental corrosion risk associated with the air exchange;

make a determination that the air exchange is associated with the corrosion management component;

in response to the determination:

estimate a corrosion risk of the air exchange based on:

the environmental corrosion risk, and

a risk reduction factor associated with the corrosion management component;

make a second determination that the corrosion risk of the air exchange indicates an unacceptable corrosion state; and

remediate the corrosion risk of the air exchange based on the unacceptable corrosion state.

11. The computing device of claim 10 , wherein remediating the corrosion risk of the air exchange comprises:

notifying an administrator of the computing device that the corrosion management component is to be replaced.

12. The computing device of claim 10 , wherein the corrosion risk is a risk based on a probability that corrosion of the air exchange will impact a functionality of the computing component.

13. A method for environmentally managing a computing device of an information handling system, comprising:

monitoring an environmental corrosion risk associated with an air exchange of a chassis that houses a computing component of the computing device, wherein a corrosion management component is:

physically connected directly to the air exchange, and

adapted to reduce a rate of corrosion of the air exchange due to gases used to manage a temperature of components of the computing device;

making a determination that the air exchange is associated with the corrosion management component;

in response to the determination:

estimating a corrosion risk of the air exchange based on:

the environmental corrosion risk, and

a risk reduction factor associated with the corrosion management component;

making a second determination that the corrosion risk of the air exchange indicates an unacceptable corrosion state; and

remediating the corrosion risk of the air exchange based on the unacceptable corrosion state.

14. The method of claim 13 , wherein remediating the corrosion risk of the air exchange comprises:

notifying an administrator of the computing device that the corrosion management component is to be replaced.

15. The method of claim 13 , wherein the corrosion risk is a risk based on a probability that corrosion of the air exchange will impact a functionality of the computing component.

16. A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for environmentally managing a computing device of an information handling system, the method comprising:

monitoring an environmental corrosion risk associated with an air exchange of a chassis that houses a computing component of the computing device, wherein a corrosion management component is:

physically connected directly to the air exchange, and

adapted to reduce a rate of corrosion of the air exchange due to gases used to manage a temperature of components of the computing device;

making a determination that the air exchange is associated with the corrosion management component;

in response to the determination:

estimating a corrosion risk of the air exchange based on:

the environmental corrosion risk, and

a risk reduction factor associated with the corrosion management component;

making a second determination that the corrosion risk of the air exchange indicates an unacceptable corrosion state; and

remediating the corrosion risk of the air exchange based on the unacceptable corrosion state.

17. The non-transitory computer readable medium of claim 16 , wherein remediating the corrosion risk of the air exchange comprises:

notifying an administrator of the computing device that the corrosion management component is to be replaced.

18. The non-transitory computer readable medium of claim 16 , wherein the corrosion risk is a risk based on a probability that corrosion of the air exchange will impact a functionality of the computing component.
