Solution Overview

Problem

Air convection systems are insufficient for cooling high-density electronic components, leading to noise disturbances and increased operational expenses due to HVAC burden, while liquid cooling systems require high maintenance and pose risks to electronic components.

Innovation Solution

A modular rack system with internal dividers that house multiple cooling sections, allowing for configuration of air or liquid cooling systems to match the cooling needs of electronic components, utilizing closed-loop air circulation and conductive heat transfer through dividers to efficiently manage heat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If air convection systems are used to cool electronic components, then the cooling system is simple and easy to implement, but the system becomes insufficient for high-density electronic components and increases noise and operational expenses

Engineering Contradiction:
Improvecooling system complexityVSAvoidcooling effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The rack is divided into multiple cooling sections, each with independent cooling capacity. Each cooling section can be configured with appropriate cooling systems (air or liquid) based on the specific heat density requirements of electronic components housed in that section, allowing targeted cooling without over-cooling or under-cooling any area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different cooling sections within the rack can have different cooling configurations - some sections use air cooling while others use liquid cooling, depending on the heat generation characteristics of the electronic components in each section. This localized approach optimizes cooling effectiveness while managing complexity.

Inventive Principle:
Principle #3Local quality

2Reliability

If liquid cooling systems are used to cool high-density electronic components, then cooling effectiveness is improved, but maintenance requirements and risk to electronic components increase

Engineering Contradiction:
Improvecooling effectivenessVSAvoidmaintenance requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cooling system is segmented into multiple independent cooling sections, each with its own cooling circuit. This modular approach allows liquid cooling to be applied only where necessary while maintaining simpler air cooling in other sections, reducing overall maintenance complexity and isolationating potential liquid cooling failures to specific sections only.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If air convection systems are used, then the system is simple to implement, but noise disturbances and operational expenses increase due to HVAC burden

Engineering Contradiction:
Improvecooling system complexityVSAvoidnoise and operational expenses
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

High heat-density electronic components are concentrated in specific cooling sections that use liquid cooling or enhanced cooling mechanisms. This localizes the cooling demand, allowing standard HVAC systems to handle the remaining cooling needs with reduced noise and energy consumption, rather than requiring high-power air convection throughout the entire rack.

Inventive Principle:
Principle #3Local quality
