Solution Overview

Problem

Existing liquid cooling cabinets suffer from gaseous coolant volatilization during maintenance, leading to environmental pollution and health risks for maintenance personnel.

Innovation Solution

A liquid cooling cabinet design with independent compartments and a connector system that allows coolant to flow through the compartments, sealing the gaseous coolant inside, reducing volatilization and enabling maintenance without losing coolant.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the upper cover of the liquid cooling cabinet is opened for maintenance, then maintenance personnel can access and maintain the IT devices, but the gaseous coolant volatilizes into the air causing loss, environmental pollution, and health risks

Engineering Contradiction:

Improvemaintenance accessibilityVSAvoidgaseous coolant loss

Core Design Contradiction:

Ease of repairVSLoss of substance

Solution Approach 1:

The cabinet is divided into multiple independent compartments, each capable of being sealed and maintained separately. This segmentation allows maintenance personnel to access specific compartments without opening the entire cabinet, thereby preventing gaseous coolant from volatilizing into the general environment while still enabling necessary maintenance operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent maintains an inert or sealed environment within each compartment to prevent the gaseous coolant from contacting and mixing with the external atmosphere. By keeping the coolant in a controlled, sealed environment during maintenance operations, volatilization and associated environmental pollution and health risks are prevented.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

2Ease of repair

If the upper cover is opened to maintain IT devices, then maintenance can be performed, but gaseous coolant volatilization occurs leading to environmental pollution and health risks

Engineering Contradiction:

Improvedevice maintenance capabilityVSAvoidenvironmental pollution and health risks

Core Design Contradiction:

Ease of repairVSObject-generated harmful factors

Solution Approach 1:

By segmenting the cabinet into independent sealed compartments, the patent enables maintenance personnel to work within a contained environment. This segmentation ensures that any gaseous coolant remains confined to the specific compartment being maintained, preventing it from polluting the external environment or exposing personnel to harmful concentrations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent maintains a controlled, sealed atmosphere within each compartment during maintenance operations. This inert environment approach prevents the gaseous coolant from escaping into the surrounding air, thereby eliminating environmental pollution and health risks associated with coolant volatilization while still allowing effective maintenance.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

3Volume of stationary object

If all IT devices are placed in a single liquid cooling cabinet, then space utilization is achieved, but maintenance requires opening the entire cabinet causing coolant loss

Engineering Contradiction:

Improvecabinet space utilizationVSAvoidcoolant loss during maintenance

Core Design Contradiction:

Volume of stationary objectVSLoss of substance

Solution Approach 1:

The cabinet is divided into multiple independent sealed compartments that can be accessed and maintained separately. This segmentation allows maintenance personnel to open only the specific compartment requiring maintenance rather than the entire cabinet, thereby maintaining high space utilization while preventing coolant loss during maintenance operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each compartment is maintained as a sealed, inert environment that prevents gaseous coolant from escaping during maintenance. This approach allows the cabinet to efficiently utilize space for housing multiple IT devices while ensuring that coolant remains contained and does not volatilize into the external environment during maintenance activities.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)
