Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server cooling systems require significant space, design efforts, and increased costs due to the need for redundant infrastructure and compatibility issues with different types of servers and data center facilities, and they lack redundancy to handle single-point failures in liquid cooling systems.
Innovation Solution
A modular adapting module that provides redundancy and flexibility by connecting to different fluid sources, allowing for dynamic reconfiguration of cooling systems, switching between open and closed loops, and integrating air-cooled heat exchangers to ensure continuous operation even if the primary fluid supply fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant rack manifolds and completely identical systems are deployed for rack level redundancy, then system reliability is improved, but device complexity and space requirements increase significantly
Solution Approach 1:
The adapting module is designed as a universal interface that can connect to multiple types of fluid sources (liquid cooling, two-phase cooling, air cooling) and server configurations through a single standardized connection. This multi-functional design eliminates the need for separate redundant systems for different cooling types, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The cooling system is segmented into modular adapting modules that can be independently connected to servers and fluid sources. Each module contains integrated valves, pumps, and heat exchangers as self-contained units, allowing redundancy to be achieved through modular replication rather than requiring completely identical complex systems.
2Reliability
If completely identical redundant systems are deployed, then system reliability is improved, but manufacturing cost increases significantly
Solution Approach 1:
The adapting module serves multiple functions across different cooling systems through a single standardized design. It can interface with liquid cooling manifolds, two-phase cooling systems, and air cooling configurations, eliminating the need to manufacture separate redundant systems for each cooling type and significantly reducing design costs.
Solution Approach 2:
The module incorporates variable parameters such as adjustable flow rates, switchable cooling modes (liquid/two-phase/air), and configurable valve positions that allow the same hardware design to adapt to different cooling requirements without requiring custom manufacturing for each configuration.
3Device complexity
If fixed cooling systems are deployed, then system simplicity is maintained, but adaptability to different server types and fluid sources is reduced
Solution Approach 1:
The adapting module incorporates dynamic control elements including electronically controlled valves, variable speed pumps, and switchable heat exchanger configurations that allow the system to dynamically adapt to different server cooling requirements and fluid sources in real-time while maintaining a relatively simple base architecture.
Solution Approach 2:
The module is designed as a universal interface that can connect to multiple types of fluid sources (liquid cooling, two-phase cooling, air cooling) and server configurations through a single standardized connection, providing broad adaptability without requiring complex fixed systems for each configuration.
4Device complexity
If single-point failure-prone liquid cooling systems are deployed, then system simplicity is maintained, but reliability is reduced
Solution Approach 1:
The adapting module incorporates backup cooling pathways and redundant fluid circulation routes that are pre-configured to activate automatically upon detection of a single-point failure. This prior cushioning ensures continuous operation without requiring complex redundant systems, maintaining simplicity while improving reliability.
Solution Approach 2:
The module provides localized redundancy at critical points within the cooling circuit, such as redundant valves and pump configurations that can independently maintain cooling flow if one component fails, rather than requiring system-wide redundancy that would increase overall complexity.

AI summary
A modular cooling system includes a fluid pump in fluid communication with one or more cooling elements to cool electronics components; a heat exchanger in fluid communication with the fluid pump; a heat exchanger valve upstream of the heat exchanger; and a fluid supply valve positioned between a cooling fluid supply and the one or more cooling elements. When the heat exchanger valve and the fluid supply valve are in a first position, fluid is directed from the cooling fluid supply to the one or more cooling elements, bypassing the heat exchanger and the fluid pump. When the heat exchanger valve and the fluid supply valve are in a second position, fluid is cut off from the cooling fluid supply and a cooling fluid return and circulated through the heat exchanger and the fluid pump.
