Server Water Cooling Metal Hose Silicon Casing Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water cooling modules in servers experience water leakage or spray at the silicon hose connections between the radiator and cold plate, posing a risk to electronic components due to the use of clips, which are ineffective in preventing damage.
Innovation Solution
The system employs metal hoses connected to the radiator using silicon casings only at the ends, with a waterproof spray plate to deflect water spray and a tray to collect any leakage, directing it outside the chassis to prevent damage to electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If clips are used to affix silicon hoses to the radiator or cold plate, then the hoses are secured in place, but water leakage or water spray occurs at the joint
Solution Approach 1:
The patent removes the clip component entirely from the hose attachment system. Instead of using clips that create leakage points, the invention uses silicon casings that directly enclose and seal the metal hose ends to the radiator or cold plate, eliminating the source of water leakage while maintaining secure attachment.
Solution Approach 2:
The patent employs composite construction by combining metal hoses with silicon casings. The silicon casing material provides sealing and waterproofing properties that complement the metal hose, creating a joint that is both mechanically strong and leak-free. This composite approach resolves the contradiction between attachment strength and waterproof reliability.
2Adaptability or versatility
If silicon hoses are used to connect radiator and cold plate, then flexibility is provided, but water leakage or spray occurs at the connection points
Solution Approach 1:
The patent uses silicon casings that function as flexible sealing shells. These casings maintain the flexibility needed for thermal expansion and vibration while providing a sealed enclosure around the hose connections. The flexible silicon material prevents water spray escape while accommodating mechanical movements, thus resolving the contradiction between flexibility and harmful water spray.
3Strength
If metal hoses are used instead of silicon hoses, then structural integrity is improved, but water leakage risk increases at connection points
Solution Approach 1:
The patent implements a nested structure where the silicon casing encloses the metal hose end and the connection interface. The silicon casing acts as an outer protective layer that seals the metal hose connection, preventing water leakage while allowing the metal hose to maintain its structural integrity. This nested configuration resolves the contradiction by combining the strengths of both materials.

AI summary
This disclosure relates to connecting a metal hose between a radiator and a cold plate that cools a CPU, or similar electronic heat generating component, whereby the metal hose is connected to the radiator with silicon casings. Waterproof spray plates are also provided to direct any water spray away from the electronic components. A water tray beneath the waterproof spray plates collects any water and directs it to a location outside the chassis.
