Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metallic materials are used to construct the cooling container, then structural strength is improved, but heat conduction through walls and electrical charge conduction worsen cooling efficiency
Solution Approach 1:
The container is divided into an outer tank and an inner liner, separating structural support functions from thermal containment functions. The metallic tank provides strength while the non-metallic liner prevents heat and electrical conduction, resolving the contradiction between structural strength and cooling efficiency.
Solution Approach 2:
A non-metallic liner acts as an intermediary layer between the metallic tank and the dielectric liquid. This liner blocks heat conduction and electrical charge conduction paths while allowing the metallic tank to maintain structural integrity, thus improving cooling efficiency without sacrificing strength.
2Ease of manufacture
If standard container configurations are used, then manufacturing simplicity is improved, but adaptability to unique cooling demands of different objects worsens
Solution Approach 1:
The container design allows dynamic adaptation through customizable liner configurations and removable support bases. While the basic tank structure remains standardized for easy manufacturing, the internal components can be modified to meet unique cooling demands of different objects, resolving the contradiction between manufacturing simplicity and adaptability.
3Device complexity
If conventional down-flow channels are used, then structural simplicity is improved, but air entrainment and flow inefficiencies worsen cooling performance
Solution Approach 1:
The down-flow channels incorporate curved transitions and rounded corners instead of sharp angles. This curvature promotes smooth liquid flow, prevents air bubble entrapment, and eliminates dead zones where air could accumulate, thereby improving cooling performance without significantly increasing structural complexity.
4Loss of energy
If non-metallic materials are used for the liner, then heat conduction is reduced improving cooling efficiency, but manufacturing precision and consistency worsen
Solution Approach 1:
The liner is designed as a thin-walled structure that can be manufactured using techniques like blow-molding or rotation molding. These methods produce consistent, uniform walls with predictable thermal properties, maintaining manufacturing precision while using non-metallic materials to reduce heat conduction and improve cooling efficiency.

AI summary
An immersion-cooling container for single-phase liquid dielectric immersion cooling. The container has a tank and a liner, which mate together to form a sealed inflow channel and one or more sealed outflow channels. The liner and the support base comprise one or more vents to permit passage of liquid dielectric coolant to envelop and cool equipment disposed inside the container. The tank sidewalls have corrugations that define one or more down-flow channels that promote passage of the liquid coolant from the container and into the outflow channels, thereby enabling continuous circulation of the liquid dielectric coolant.
