Immersion Server Top-Panel Coolant Distribution for High-TDP Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server type information handling systems face challenges in efficiently dissipating the thermal design power (TDP) of high-power components due to limited thermally conductive liquid volume, leading to increased cost and complexity with hybrid DLC/immersion cooling solutions.
Innovation Solution
A liquid cooling liquid distribution system with integrated and ducted liquid pathways is implemented, focusing coolant flow on high-power components within a hermetically sealed immersion chassis, using a chassis top panel with a liquid distribution chamber and ducted apertures to direct coolant flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If hybrid direct liquid cooling and immersion approaches are used to cool high power components, then cooling effectiveness is improved, but cost and system complexity increase
Solution Approach 1:
The patent combines direct liquid cooling and immersion cooling into a unified system where the chassis itself serves as the cooling vessel. The hermetically sealed chassis contains cooling liquid that directly contacts high power components through designated pathways, eliminating the need for separate cooling loops and reducing system complexity while maintaining cooling effectiveness.
Solution Approach 2:
The chassis structure serves multiple functions: it provides mechanical support for components, acts as a hermetic seal to contain the cooling liquid, and functions as the cooling system itself through integrated liquid pathways. This multi-functionality reduces the number of separate components needed and simplifies the overall system architecture.
2Reliability
If hermetically sealed chassis with integrated liquid pathways is used, then cooling liquid is contained effectively, but manufacturing complexity increases
Solution Approach 1:
The liquid distribution pathways are integrated directly into the chassis structure rather than being separate components. This merging of functions allows the chassis to serve as both the containment vessel and the distribution system, reducing the number of assembly steps and manufacturing complexity while ensuring reliable liquid containment through the hermetic seal.
