Immersion Cooling Fluid With Plasticizer for Cable Surface Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Components in computing systems immersed in coolant degrade faster due to loss of plasticity, particularly in immersion cooling environments, leading to issues like cracking and splitting of connection cables and wires.
Innovation Solution
A cooling fluid comprising a coolant with a diffusible plasticizer is used, where the plasticizer concentration is at least 0.005 weight ratio, allowing it to replenish and maintain the plasticity of plasticized surfaces by diffusing into the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If immersion cooling is used to cool computing devices, then cooling efficiency is improved, but components with plasticized surfaces degrade faster due to loss of plasticity
Solution Approach 1:
A plasticizer is added to the coolant to act as an intermediary substance that prevents the leaching of plasticizers from cable and wire surfaces. The plasticizer in the coolant replenishes the plasticized surfaces, maintaining their flexibility and preventing degradation while the coolant continues to provide effective cooling.
Solution Approach 2:
The chemical composition of the coolant is changed by adding a plasticizer. This parameter change transforms the coolant from a simple cooling medium to a dual-function fluid that both cools and protects plasticized surfaces by preventing plasticizer loss.
2Temperature
If plasticized surfaces are exposed to coolant, then cooling is achieved, but plasticizers are lost from the surfaces causing cracking and splitting
Solution Approach 1:
The added plasticizer in the coolant serves as a mediator that counteracts the leaching process. It diffuses into the plasticized surfaces and replenishes the lost plasticizer, preventing cracking and splitting while allowing continuous cooling exposure.
Solution Approach 2:
The harmful effect of plasticizer leaching is converted into a benefit by adding plasticizer to the coolant. The coolant, which initially causes plasticizer loss, becomes a source of plasticizer replenishment, turning the harmful leaching process into a beneficial exchange that maintains surface integrity.
