Chassis Environmental Control Using Corrosion Rate Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face premature failures due to corrosion caused by exposure to gases containing water vapor and reactive species, leading to reduced service life and increased operational costs.
Innovation Solution
Implementing an environmental management system that monitors corrosion rates and modifies environmental conditions, such as temperature and humidity, to reduce the risk of corrosion by increasing ambient temperature, decreasing fan speeds, and adjusting gas intake conditions.

1Duration of action of stationary object
If environmental control components are used to manage corrosion, then service life of components is extended, but device complexity increases
Solution Approach 1:
The system performs preliminary corrosion risk assessment by analyzing environmental data and corrosion rates before actual corrosion damage occurs. This allows preventive environmental control modifications to be made in advance, extending component service life while managing system complexity through proactive rather than reactive measures.
Solution Approach 2:
The environmental manager continuously monitors corrosion rates and environmental conditions, using this feedback to dynamically adjust environmental control component operations. This closed-loop feedback mechanism optimizes corrosion protection while avoiding unnecessary system complexity by only activating controls when actually needed based on real-time conditions.
2Reliability
If environmental control modifications are made to reduce corrosion, then reliability of component is improved, but use of energy increases
Solution Approach 1:
The system applies environmental control modifications only to the extent necessary to achieve acceptable corrosion rates, rather than continuously maximizing protection. The environmental manager assesses whether full environmental control is needed or if partial measures suffice, reducing energy consumption while maintaining adequate component reliability.
Solution Approach 2:
The system dynamically changes environmental parameters such as temperature and humidity levels based on actual corrosion risk assessment. Rather than maintaining fixed conservative environmental conditions that would consume excessive energy, the system adjusts parameters in real-time based on corrosion rates and environmental data, optimizing the balance between reliability and energy usage.

AI summary
A computing device of an information handling system includes an environmental control component and an environmental manager. The environmental control components identifies an aggregate amount of corrosion of a component of the information handling system; obtains a rate of corrosion associated with the component; makes a determination that the rate of corrosion indicates that the component will suffer a premature failure; in response to the determination: identifies an environmental control modification that will remediate the premature failure of the component; and updates an operation of the environmental control component based on the environmental control modification.
