Fluid Distribution Assembly for Low-Volume Immersion Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-phase immersion cooling systems require a large amount of coolant, leading to significant cost due to the need for a large volume of coolant to immerse heat sources fully, which is inefficient and costly.
Innovation Solution
A fluid distribution assembly with a housing and fluid-driving component that pumps coolant out of a coolant chamber, allowing efficient immersion cooling with reduced coolant volume by maintaining a higher liquid level within the chamber to cover heat sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional single-phase immersion cooling fully immerses heat sources in a large volume of coolant, then effective heat dissipation is achieved, but coolant consumption and cost increase significantly
Solution Approach 1:
The system divides the cooling space into multiple independent coolant chambers, each containing a localized heat source. This segmentation allows each chamber to use minimal coolant volume while collectively cooling multiple heat sources, resolving the contradiction between effective heat dissipation and coolant consumption.
Solution Approach 2:
The coolant chambers are nested within a larger cooling system structure, with each chamber independently containing its heat source and minimal coolant volume. This nested arrangement enables the system to achieve comprehensive cooling while maintaining low overall coolant consumption.
2Reliability
If the liquid level of coolant is raised to cover the tallest heat source, then complete immersion cooling is achieved, but the amount of coolant required increases considerably
Solution Approach 1:
Instead of raising the liquid level in one large container to cover all heat sources, the system segments the cooling space into multiple chambers, each with its own heat source and minimal coolant volume. This ensures complete immersion coverage for each heat source while minimizing total coolant amount.
Solution Approach 2:
The system transitions from a single large-volume horizontal immersion approach to a multi-chamber vertical arrangement, where coolant is contained in separate chambers at different levels. This dimensional change allows complete heat source coverage in each chamber without requiring proportionally large coolant volumes.

The system effectively cools heat sources with a minimal amount of coolant, reducing costs by approximately 3.74 to 3636 USD per centimeter drop in coolant level, depending on the rack size, while maintaining efficient heat dissipation.
Implementation Method 1
at least one fluid-driving component in fluid communication with the coolant chamber configured for accommodating the at least one heat source, and the at least one fluid-driving component is configured to pump fluid out of the coolant chamber
Implementation Method 2
the coolant is in direct thermal contact with these components so that the immersion cooling is much more efficient than air cooling
