Immersion Rack Case Drainage to Prevent Coolant Spillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rack systems for housing electronic devices face issues with the spillage of dielectric immersion cooling liquid during de-racking, leading to economic loss and environmental concerns due to the high cost and quantity of the liquid used.
Innovation Solution
The introduction of an immersion case with a drainage opening that allows for the removal of a portion of the immersion cooling liquid prior to de-racking, featuring a user-actuated, liquid-proof closing mechanism, and optional valve or pump for efficient liquid management, along with a pivot mechanism to facilitate drainage without spilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If immersion cooling liquid is used for efficient cooling, then cooling efficiency is improved, but risk of spilling during de-racking increases
Solution Approach 1:
The drainage opening allows the immersion cooling liquid to be removed from the immersion case before the de-racking operation is performed. This preliminary drainage action eliminates the liquid that would otherwise spill during subsequent handling and removal of the immersion case from the rack structure.
Solution Approach 2:
The drainage opening provides a dedicated extraction path for the immersion cooling liquid, separating the liquid removal function from the immersion case structure. This allows the liquid to be extracted and collected separately before the case is de-racked, preventing spillage during the de-racking process.
2Ease of operation
If drainage opening is added to immersion case, then liquid management is improved, but device complexity increases
Solution Approach 1:
The immersion case is segmented into functional zones by incorporating a drainage opening, which divides the case into a liquid retention area and a drainage area. This segmentation allows for controlled liquid removal while maintaining the overall simplicity of the case structure.
Solution Approach 2:
The drainage opening acts as an intermediary element between the immersion cooling liquid and the external collection container. This intermediary structure enables controlled liquid transfer without requiring complex pumping or valve mechanisms, maintaining simplicity while improving liquid management.
