Solution Overview

Problem

Conventional immersion cooling facilities face challenges in effectively suppressing fires within the immersion cooling apparatus due to the risk of oil or electrical fires and the difficulty of penetrating fire extinguishing agents through covers, leading to potential damage to servers and equipment when total flooding-type systems are activated.

Innovation Solution

An immersion cooling apparatus with a local automatic fire suppression system that includes a cover unit, heat detection, fire extinguishing gas discharging structure, and a fireproof screen to uniformly distribute fire extinguishing gas and maintain concentration, even when the cover is open, thereby preventing fire spread.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a total flooding-type fire extinguishing system is installed in the server room, then fire suppression capability is improved, but damage to servers and equipment worsens due to extensive activation

Engineering Contradiction:

Improvefire suppression capabilityVSAvoiddamage to servers and equipment

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fire suppression system is segmented into localized units positioned at specific immersion cooling facilities rather than a single centralized system covering the entire server room. This allows fire suppression to be confined to the specific facility where fire occurs, preventing extensive damage to other servers and equipment while maintaining effective fire suppression capability at the source.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a cover is provided on the immersion cooling facility, then coolant containment is improved, but fire extinguishing gas penetration worsens

Engineering Contradiction:

Improvecoolant containmentVSAvoidfire extinguishing gas penetration

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fire extinguishing gas discharge structure is nested within the cover unit itself, with discharge nozzles integrated into the cover's configuration. This allows the cover to maintain its coolant containment function while simultaneously providing a built-in mechanism for fire extinguishing gas penetration, eliminating the need to compromise cover integrity for fire suppression access.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Reliability

If fire extinguishing gas is discharged into the immersion cooling facility, then fire suppression is improved, but gas distribution uniformity worsens

Engineering Contradiction:

Improvefire suppression effectivenessVSAvoidgas distribution uniformity

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

Multiple fire extinguishing gas discharge nozzles are distributed at different locations on the cover unit, each targeting specific areas of the immersion cooling facility. This local distribution approach ensures uniform gas coverage throughout the facility by placing discharge points strategically rather than relying on a single centralized discharge location, thereby improving gas distribution uniformity while maintaining fire suppression effectiveness.

Inventive Principle:

Principle #3Local quality
