Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing methods for two-phase immersion cooling systems in servers fail to achieve airtightness while allowing for electrical connections and data transmission, leading to potential fluid leakage and system failure.
Innovation Solution
A sealing method involving a frame surrounding a server component, with different viscosity colloids used to create an airtight wall, and a housing fixation with screws and sealing materials to maintain airtightness while enabling communication between internal and external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a general sealing method is used to seal the casing, then the airtightness of the casing is improved, but the electrical connection and data transmission through the casing is blocked
Solution Approach 1:
The sealing solution is divided into multiple segments: a frame structure that defines the sealing boundary, first colloid that fills gaps between the component and frame, and second colloid that seals the housing. This segmentation allows each part to perform its specific function while maintaining overall airtightness and electrical connectivity.
Solution Approach 2:
The frame acts as an intermediary structure between the component and housing, creating a sealed chamber that allows electrical connections to pass through while maintaining airtightness. The colloids serve as intermediary sealing materials that fill gaps without blocking electrical signals.
2Reliability
If the casing is made airtight to prevent dielectric fluid leakage, then the reliability of the cooling system is improved, but the connection between internal and external components is compromised
Solution Approach 1:
The sealing structure applies different properties to different locations: the frame provides structural support and defines the sealing boundary, the first colloid fills gaps at the component-frame interface, and the second colloid seals the housing. This local differentiation allows airtightness where needed while maintaining electrical connectivity pathways.
3Reliability
If a sealing structure is added to maintain airtightness, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The frame serves multiple functions: it provides structural support, defines the sealing boundary, and allows electrical connections to pass through. The colloids simultaneously fill gaps, seal interfaces, and maintain electrical connectivity. This multi-functionality reduces the need for additional separate components.

AI summary
A sealing method for a server includes: surrounding a part of a component by a frame; coating a first colloid on the part of the component and an inner surface of the frame; filling a second colloid between the part of the component and the inner surface of the frame and covering the first colloid, in which the first colloid and the second colloid have different coefficients of viscosity; fixing the frame on a housing; and sealing a gap between the frame and the housing.
