Solution Overview

Problem

Existing immersive cooling systems for data centers face challenges in efficiently extracting and maintaining electronic devices, particularly due to the viscosity of dielectric cooling liquids, which can lead to spills and operator safety issues.

Innovation Solution

An extraction system comprising a nozzle to contain the spread of immersion cooling liquid, a lifting mechanism to remove the electronic device from the container, and a liquid dispersing device to aspirate the cooling liquid, all coordinated by a controller to facilitate safe and efficient extraction and reorientation of the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If immersion cooling liquid is used for cooling electronic devices, then cooling efficiency is improved, but handling difficulty increases due to high viscosity

Engineering Contradiction:
Improvecooling efficiencyVSAvoidhandling difficulty
Core Design Contradiction:
TemperatureVSEase of operation

Solution Approach 1:

The patent introduces an extraction system with a lifting mechanism and dispersing means as an intermediary between the immersion cooling liquid and the operator. This system handles the viscous liquid automatically, eliminating the need for operators to directly manipulate the high-viscosity cooling liquid, thus resolving the handling difficulty while preserving cooling efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The extraction system is designed to automatically dispel and collect the immersion cooling liquid without requiring manual intervention. The lifting mechanism extracts the device while the dispersing means automatically manages the viscous liquid, allowing the system to serve itself and eliminating the operational burden on users

Inventive Principle:
Principle #25Self-service

2Temperature

If immersion cooling liquid is used, then thermal contact is improved, but cleaning complexity increases

Engineering Contradiction:
Improvethermal contactVSAvoidcleaning complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The extraction system acts as an intermediary that performs the cleaning function automatically. The dispersing means and collection container handle the removal and containment of cooling liquid from extracted devices, eliminating the need for operators to manually clean devices and reducing cleaning complexity while maintaining effective thermal contact during operation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If manual extraction is performed, then device removal is possible, but spill risk increases

Engineering Contradiction:
Improvedevice removalVSAvoidspill risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The extraction system serves as an intermediary between the operator and the viscous cooling liquid. The lifting mechanism and dispersing means automatically manage the extraction process, containing the cooling liquid within the collection container and preventing spills that would occur during manual handling

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system prepares for potential spills in advance by providing a collection container to catch and contain the immersion cooling liquid. The dispersing means is positioned to prevent liquid from spreading before it can cause harm, cushioning against the harmful effects of spills before they occur

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
