Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid immersion cooling platforms face challenges in effectively filtering contaminants, ensuring easy access for component swapping, and minimizing vibrations and movements that can impact system stability.
Innovation Solution
The implementation of a dual-filter system with clamped lids and stabilizers in a liquid immersion cooling platform, where the first filter is used initially to capture debris and contaminants, and the second filter is engaged after a threshold period to maintain fluid purity, combined with a lid design for easy access and stabilizers to minimize vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single filter is used in the immersion cooling system, then the device complexity is reduced, but the filtration efficiency deteriorates over time as the filter becomes saturated with contaminants
Solution Approach 1:
The filter system is segmented into multiple filters (first filter, second filter, and optional third filter) that operate in sequence or parallel. This segmentation allows the system to maintain high filtration efficiency by distributing the contaminant load across multiple filtering stages, with each filter handling specific types or levels of contaminants.
Solution Approach 2:
The system implements a filter replacement strategy where saturated filters are discarded and replaced with fresh filters. The controller monitors filter saturation levels and automatically triggers filter replacement, ensuring the system always has active filters with high filtration capacity without requiring manual intervention.
2Ease of operation
If a lid is provided for component access, then the ease of operation is improved, but the stability of the system deteriorates due to vibrations and movements
Solution Approach 1:
The lid is segmented into a removable component that can be independently accessed without disturbing the entire system. The lid is designed to be removable from the tank, allowing operators to access components while minimizing vibrations and movements that would affect the overall system stability.
Solution Approach 2:
The lid is extracted as a separate, removable element from the main tank structure. This allows the lid to be independently managed - removed when component access is needed, and securely reattached when not in use, thereby isolating the access function from the stability requirements of the main cooling system.
3Ease of manufacture
If filters are positioned outside the tank, then the ease of manufacture is improved, but the loss of substance increases due to fluid leakage during filter changes
Solution Approach 1:
The filters are nested within the tank structure, positioned inside the tank rather than externally mounted. This nested configuration allows filters to be accessed and replaced through the removable lid without breaking the sealed environment, preventing dielectric fluid leakage and loss during filter maintenance operations.
Solution Approach 2:
The removable lid acts as an intermediary that provides controlled access to the filters inside the sealed tank. By using the lid as the access interface, the system maintains its sealed environment during filter changes, allowing filter replacement without exposing the internal fluid to external contamination or loss.
4Productivity
If the pump continuously circulates fluid through filters, then the productivity is improved, but the use of energy increases
Solution Approach 1:
The pump operates periodically rather than continuously, circulating fluid through filters only when contamination levels warrant filtration. The controller monitors system conditions and activates the pump and filters only when needed, reducing energy consumption while maintaining adequate fluid quality and system productivity.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor fluid quality, filter saturation levels, and system operating conditions. Based on this feedback, the controller intelligently controls pump operation and filter engagement, activating them only when contamination thresholds are exceeded, thereby optimizing the balance between productivity and energy consumption.

AI summary
A cooling system includes a sump area configured to hold a dielectric fluid, a bath area that receives a computer component, a first filter, a second filter, and a pump that draws the dielectric fluid from the sump area, passes the dielectric fluid through at least one of the first filter or the second filter, and delivers the dielectric fluid to the bath area. The bath area holds the dielectric fluid.
