Drip Tray With Absorbent Material For Liquid Cooling Leak Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges with heat management due to increased processing power leading to higher temperatures, which can stress or damage air cooling systems, and liquid-assisted cooling systems pose risks of fluid leaks that can damage electronic components.
Innovation Solution
A drip tray with an absorbent material, such as compressed plant fiber or super-absorbent polymer, is positioned under the cooling system to collect and contain fluid leaks, equipped with a liquid sensor to detect fluid presence and adjust the operation of electronic components to reduce heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid-assisted cooling is used to improve heat dissipation efficiency, then cooling performance is improved, but the risk of fluid leakage increases
Solution Approach 1:
The patent implements a drip tray positioned beneath the liquid cooling system components (heat exchanger, piping, cooling blocks) to collect and contain any fluid that leaks from the system. This preventive measure cushiones against the harmful effects of leakage before they can reach and damage electronic components, thereby enabling the use of liquid-assisted cooling without proportionally increasing system failure risk.
2Reliability
If absorbent material is added to the drip tray to enhance fluid collection, then containment capability is improved, but device complexity increases
Solution Approach 1:
The patent incorporates an absorbent material within the drip tray that possesses porous characteristics, enabling it to actively wick up and retain leaked fluid through capillary action. This approach enhances the drip tray's containment capability beyond passive collection, as the material automatically draws in and holds fluid, providing an additional layer of protection against electronic component damage.
Solution Approach 2:
The drip tray is constructed as a composite structure combining a structural base (for containment and positioning) with an absorbent material layer (for fluid absorption and retention). This composite approach integrates two different material functions into a single component, enhancing overall reliability while managing the added complexity through functional integration rather than separate assemblies.
3Measurement precision
If a liquid sensor is installed to detect fluid presence, then leak detection capability is improved, but device complexity increases
Solution Approach 1:
The patent installs a liquid sensor within the drip tray that continuously monitors for the presence of leaked fluid and provides feedback signals to the system controller. When fluid is detected, the controller can respond by shutting down the liquid cooling system, adjusting operational parameters, or alerting operators, thereby creating a closed-loop safety mechanism that enhances leak detection and response capabilities.
Solution Approach 2:
The liquid sensor enables the cooling system to self-monitor and self-protect against leakage damage. By automatically detecting fluid presence and triggering appropriate responses without human intervention, the system performs its own safety verification and protection functions, reducing the need for external monitoring and manual intervention while enhancing overall reliability.

AI summary
Cooling of an information handling system can be provided liquid-assisted cooling apparatus with liquid. The liquid-assisted cooling apparatus may comprise a drip tray component positioned under a liquid-assisted cooling module having a cooling block, a heat exchanger, and piping connecting the cooling block and heat exchanger. The drip tray can collect fluid leaked by or from the liquid-assisted cooling module. The drip tray may include an absorbent material to contain the leaked fluid and/or a liquid sensor to detect the presence of fluid in the drip tray. The liquid sensor may be coupled to a controller configured to adjust operation of one or more electronic components cooled by the liquid-assisted cooling apparatus when fluid is determined to be present in the drip tray.
