Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Datacenters face challenges in achieving low latency and efficient cooling while considering proximity to customers, privacy, security, environmental impact, and cost, as existing solutions do not effectively utilize underwater or submerged cooling methods to address these factors.
Innovation Solution
A datacenter or datacenter module is immersed in a dielectric cooling fluid, which is sealed within a container and uses a heat transfer subsystem to cool the components, allowing for submersion in water to equalize pressure and leverage the heat sink of the surrounding water for efficient cooling, potentially using polymers for the container and employing immersion cooling techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If datacenter is positioned close to customer base to reduce latency, then speed is improved, but security and environmental protection become more difficult to ensure
Solution Approach 1:
The datacenter is relocated from traditional terrestrial locations to an underwater environment, utilizing the third dimension (depth) to resolve the contradiction. This spatial relocation enables proximity to customer bases while simultaneously providing enhanced security through the natural protective barrier of water and isolation from terrestrial threats.
Solution Approach 2:
A dielectric fluid serves as an intermediary medium between the external water environment and the internal datacenter components. This intermediary provides both cooling functionality and electrical insulation, enabling secure operation while maintaining the underwater position for security and proximity benefits.
2Temperature
If conventional cooling methods are used in datacenter, then cooling function is provided, but heat dissipation efficiency is insufficient and energy consumption is high
Solution Approach 1:
The datacenter utilizes the surrounding water environment as a natural heat sink, allowing the system to cool itself passively through thermal conduction and convection. The cold water from the deep ocean provides continuous cooling without requiring additional energy input for active refrigeration systems.
Solution Approach 2:
The dielectric fluid undergoes phase transitions or thermal exchange with the surrounding water, efficiently transferring heat from datacenter components to the external environment. This phase-based heat transfer mechanism provides superior cooling efficiency compared to conventional air-based cooling systems.
3Reliability
If datacenter is submerged in deep water to enhance security and cooling, then reliability is improved, but container material strength requirements increase
Solution Approach 1:
The dielectric fluid acts as a pressure equalization intermediary, filling the interior space and balancing the external water pressure against the container walls. This pressure equalization eliminates the need for extremely strong materials to withstand deep water pressure, while still enabling deployment in deep water locations for enhanced security.
Solution Approach 2:
The system changes the internal pressure parameter by filling with dielectric fluid, which equalizes with external water pressure. This parameter change allows the use of lighter, less expensive materials while maintaining structural integrity at deep water depths, thus enabling security-enhancing submersion without proportionally increasing material strength requirements.
4Ease of operation
If terrestrial datacenter locations are used for easy access and maintenance, then ease of operation is improved, but cooling efficiency and environmental impact are worsened
Solution Approach 1:
The patent converts the previously harmful effect of water (corrosion risk to electronics) into a beneficial cooling medium. By submerging the datacenter and using dielectric fluid for both cooling and electrical insulation, the system transforms the aquatic environment from a threat into a resource for efficient cooling and enhanced security.

AI summary
The subject disclosure is directed towards a datacenter or partial datacenter (e.g., a datacenter module) contained in a sealed container. The container may be filled with a cooling fluid, such as a dielectric fluid, to help cool the datacenter components. The container and its internal datacenter or datacenter portion may be submerged in water, in which event the fluid also helps to equalize the external water pressure.
