Liquid Cooling Leak Detection Enclosure for Contained Fittings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems with liquid cooling systems face challenges in detecting and containing leaks, which can lead to catastrophic system failure due to moisture ingress and corrosion.
Innovation Solution
A leak detection enclosure is designed to couple with the liquid cooling system's cold plate, enclosing the cooling hose fittings within a contained area. A planar cover seals the enclosure to prevent external moisture ingress and ensures any leaks are detected and contained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling system is implemented to manage thermal energy, then thermal management efficiency is improved, but risk of fluid leak and system failure increases
Solution Approach 1:
The liquid cooling system is segmented into a sealed enclosure containing the cold plate and hose fittings, separating the cooling function from the risk of fluid leakage into the housing. This enclosure allows the liquid cooling system to operate efficiently while containing potential leaks within a defined boundary.
Solution Approach 2:
A leak detection sensor acts as an intermediary between the liquid cooling system and the information handling system housing. The sensor detects the presence of leaked fluid and generates a signal to alert the system, providing early warning before catastrophic failure occurs.
2Reliability
If leak detection sensor is added to detect fluid leaks, then system reliability is improved, but device complexity increases
Solution Approach 1:
The leak detection sensor is merged with the enclosure structure, where the sensor is positioned within the sealed enclosure to detect fluid leaks. This integration minimizes additional complexity by combining the detection function with the existing enclosure rather than adding a separate, independent detection system.
3Object-affected harmful factors
If planar cover is used to seal the enclosure, then moisture ingress prevention is improved, but manufacturing precision requirements increase
Solution Approach 1:
A planar cover made of flexible material is used to seal the enclosure. This flexible seal can conform to slight variations in manufacturing tolerances while still providing effective moisture ingress prevention, reducing the stringency of manufacturing precision requirements compared to rigid sealing mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The leak detection enclosure effectively isolates the liquid cooling system from external moisture, promptly detecting any leaks and preventing damage to the information handling system components, thereby ensuring system reliability and preventing catastrophic failures.
Implementation Method 1
A leak detection sensor disposed within the leak detection enclosure to detect leaked fluid
Data Source
AI summary
Information handling system thermal management of processing components, such as CPU, GPU and/or memory, by a liquid cooling system is protected by a leak detection enclosure having a leak detection sensor disposed in an interior. The leak detection enclosure has a frame coupled to a cold plate that encloses the leak detection sensor and cooling fluid hose fittings so that leaked fluid is trapped within the enclosure for detection by the leak detection sensor. A planar cover couples to the frame upper side over the leak detection circuit and the cooling fluid hose fittings to provide ready assembly and an inexpensive adaptable form factor.
