Data Center Filter Frame Ventilation for Particulate Control

Solution Overview

Problem

Existing datacenter cooling systems face challenges in filtering particulate matter from airflow, particularly in direct air-cooling systems, which can damage sensitive equipment, while indirect systems are more expensive and less efficient.

Innovation Solution

A scalable filter frame system positioned orthogonally to airflow, using pivotally coupled frame uprights and crossbars to accommodate uneven floors, with removable filters and prefilter clamps to reduce particulate matter, ensuring stability and ease of maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If direct air-cooling systems are used to cool datacenter equipment, then cooling efficiency is improved, but particulate matter in the airflow may damage sensitive equipment

Engineering Contradiction:

Improvecooling efficiencyVSAvoidparticulate matter damage

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The filtration system is divided into multiple independent filter units (first filter unit, second filter unit, third filter unit) that can be individually installed, maintained, and replaced. Each filter unit handles a portion of the airflow, allowing modular segmentation of the filtration function while maintaining overall system effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Filter units are introduced as intermediary components between the incoming airflow and the sensitive computer equipment. These filters act as mediators that remove particulate matter from the airflow before it reaches the equipment, preventing damage while allowing cooling air to pass through.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If filters are installed in the airflow path to remove particulate matter, then equipment protection is improved, but system complexity increases

Engineering Contradiction:

Improveparticulate matter reductionVSAvoidfiltration system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The filtration system is divided into multiple independent filter units (first filter unit, second filter unit, third filter unit) that can be individually installed, maintained, and replaced. Each filter unit handles a portion of the airflow, allowing modular segmentation of the filtration function while maintaining overall system effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter units are designed with universal mounting features including top mounting plates, bottom mounting plates, and side mounting plates that can be attached to various surfaces (walls, ceilings, floors). This multi-functional mounting capability allows the same filter unit design to be installed in different locations and configurations without requiring custom designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If multiple filter units are installed in series to improve filtration effectiveness, then particulate removal is improved, but pressure drop increases

Engineering Contradiction:

Improveparticulate removal effectivenessVSAvoidairflow pressure drop

Core Design Contradiction:

Object-affected harmful factorsVSStress or pressure

Solution Approach 1:

The filtration system is divided into multiple independent filter units (first filter unit, second filter unit, third filter unit) that can be individually installed, maintained, and replaced. Each filter unit handles a portion of the airflow, allowing modular segmentation of the filtration function while maintaining overall system effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of stacking multiple filters in a single series path (one-dimensional arrangement), the system distributes multiple filter units across different spatial locations and airflow paths (multi-dimensional arrangement). This allows parallel filtration capacity to be added without proportionally increasing the pressure drop experienced by individual airflow streams.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
