Liquid Cooling Conduits for Information Handling Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cooling systems for information handling resources, such as those using fans, face challenges with increased heat density and power consumption, leading to noise and inefficient heat dissipation, while liquid cooling systems often only cool a few components and still generate noise and heat in the surrounding environment.
Innovation Solution
A system that uses fluidic conduits to convey a flowing fluid thermally coupled to information handling resources, transferring heat to a cooling unit which then dissipates it to another medium, potentially air, without the need for fans within the information handling system enclosure, allowing for remote heat emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fan-based air cooling is used to cool information handling resources, then heat dissipation is achieved, but power consumption increases and noise is generated
Solution Approach 1:
The patent replaces the mechanical fan-based air cooling system with a liquid cooling system that uses fluid circulation through conduits and channels. This substitution eliminates the need for mechanical fans, thereby reducing power consumption and noise while maintaining effective heat dissipation through thermal conduction and convection in the liquid medium.
Solution Approach 2:
The patent implements a liquid cooling system that circulates coolant through fluid conduits and channels formed in support members. This hydraulic approach uses fluid flow to transfer heat from information handling resources to cooling units, providing efficient cooling without the drawbacks of fan-based air cooling systems.
2Temperature
If fan-based air cooling is used to cool information handling resources, then heat dissipation is achieved, but noise is generated
Solution Approach 1:
The patent eliminates mechanical fans by replacing them with a liquid circulation system. The noise generated by fan blades and motor operation is replaced by the quieter operation of liquid flow through conduits, significantly reducing the harmful noise factor while maintaining cooling effectiveness.
3Temperature
If traditional air cooling with increased airflow is used to cool denser information handling resources, then cooling effectiveness improves, but system size increases
Solution Approach 1:
The patent uses liquid cooling through conduits and channels that can be integrated into the existing system structure. The liquid cooling system provides superior heat transfer efficiency per unit volume compared to air cooling, allowing effective cooling of dense information handling resources without proportionally increasing system size.
4Temperature
If fans are used to cool information handling resources, then heat dissipation is achieved, but heat is transferred to surrounding areas
Solution Approach 1:
The patent extracts the heat dissipation function from the local environment by using liquid cooling that can transport heat away from information handling resources through fluid conduits to remote cooling units. This separates the heat generation location from the heat discharge location, preventing heat from being transferred to surrounding areas.
Solution Approach 2:
The patent uses coolant liquid as an intermediary medium to transfer heat from information handling resources through conduits to cooling units. This intermediary allows heat to be moved away from the immediate environment, preventing direct heat discharge to surrounding areas while maintaining cooling effectiveness.
