Corrosion Risk Control in Information Handling Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face corrosion issues due to high humidity levels, leading to device failure and increased maintenance costs, as existing cooling methods often introduce humid outdoor air that condenses and forms corrosive water layers on devices.
Innovation Solution
A corrosion manager system that monitors ambient temperature and humidity levels, determining a corrosion risk value and adjusting device threshold settings to increase the ambient temperature, thereby reducing humidity and mitigating corrosion risks by modifying fan speeds, heater control, and device throttling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling methods are used to reduce ambient temperature, then device temperature is controlled, but humidity levels increase causing corrosion
Solution Approach 1:
The system dynamically adjusts operational parameters (fan speed, device throttling, heater control) based on real-time monitoring of temperature and humidity levels. When corrosion risk is detected, the system modifies these parameters to increase ambient temperature and decrease humidity, thereby resolving the contradiction between temperature control and corrosion prevention
Solution Approach 2:
The corrosion manager continuously monitors ambient temperature and humidity levels, determines corrosion risk values, and provides feedback to adjust device threshold settings. This closed-loop feedback mechanism enables the system to respond to changing environmental conditions and maintain optimal operating parameters to prevent corrosion while managing temperature
2Object-affected harmful factors
If device threshold settings are modified to increase ambient temperature, then humidity levels decrease reducing corrosion, but device operating temperature increases
Solution Approach 1:
The system dynamically adjusts device threshold settings based on real-time environmental conditions and corrosion risk assessments. By making the threshold settings adaptive rather than static, the system can modify fan speeds, heater control, and device throttling to achieve the dual objective of reducing humidity while managing device operating temperature within safe limits
