Chassis Airflow Conditioning to Limit Corrosion in Computing Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face corrosion issues due to gases used for thermal management, which can lead to premature component failure and increased operational costs, as these gases can cause chemical reactions and condensation, resulting in corrosion products that impact the system's functionality and service life.
Innovation Solution
The implementation of environmental control components such as airflow disrupters and nozzle plates to modify the airflow characteristics, reducing condensation formation propensity and corrosion risk by dehumidifying, redirecting, and increasing the turbulence of gases before they interact with sensitive components, thereby mitigating corrosion without significantly increasing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If gas flow is used for thermal management of computing components, then heat dissipation is improved, but corrosion of components occurs due to condensation formation
Solution Approach 1:
The patent introduces an environmental control component that modifies the gas flow characteristics before it reaches the computing component. By preliminarily reducing the condensation formation propensity of the gas flow through passive means (such as heating elements or flow direction changes), the system prevents corrosion before it occurs while maintaining effective thermal management
Solution Approach 2:
The environmental control component acts as an intermediary between the thermal management gas flow and the computing component. It modifies the gas flow properties (temperature, humidity, velocity) to reduce condensation formation propensity, thereby mediating the harmful interaction between the gas flow and the corrosion-sensitive computing component
2Duration of action of stationary object
If extensive gas conditioning is implemented to reduce corrosion, then component service life is extended, but power consumption increases
Solution Approach 1:
The environmental control component is designed to passively reduce condensation formation propensity without requiring significant external power input. The system utilizes the existing gas flow characteristics and employs passive mechanisms (such as natural convection, minimal heating, or flow redirection) to achieve corrosion protection, allowing the system to protect itself with minimal energy expenditure
Solution Approach 2:
The patent modifies key parameters of the gas flow (temperature, velocity, humidity) in a controlled manner to reduce condensation formation. By making targeted parameter changes only where and when necessary (using passive environmental control), the system extends component service life without implementing extensive active gas conditioning that would consume excessive power

AI summary
An information handling system includes a computing component that is sensitive to corrosion; and a chassis in which the computing component is disposed. The chassis receives an airflow used to thermally manage the computing component, and expels the airflow after thermally managing the computing component. The information handling system also includes an environmental control component that reduces a condensation formation propensity of a portion of the airflow that traverses the chassis proximate to the computing component.
