Solution Overview

Problem

Data centers face high energy consumption for cooling, with traditional thermostats using 50-60% of total electricity, and existing methods for introducing outside air for cooling are limited in efficiency and flexibility.

Innovation Solution

A server room cooling device that uses external natural air, incorporating a demister filter, mist ejection unit, and cooling unit to supply cooled air, with a modular design allowing for continuous operation and automatic adjustment of mist and air flow based on temperature and humidity, and includes a dual-filter system for foreign substance removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If traditional thermostats are used to cool data centers, then cooling function is provided, but energy consumption increases significantly (50-60% of total electricity)

Engineering Contradiction:
Improveenergy consumptionVSAvoidcooling function
Core Design Contradiction:
Use of energy by stationary objectVSReliability

Solution Approach 1:

The patent extracts the cooling function from the traditional thermostat system and implements it through a dedicated outer air introduction device that brings in cold outside air directly into the server room, separating the cooling function from the main power consumption source

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system utilizes naturally cold outside air as a free cooling source, allowing the environment itself to provide the cooling function without requiring additional energy input from thermostats or refrigeration systems

Inventive Principle:
Principle #25Self-service

2Use of energy by stationary object

If outer air is introduced for cooling, then energy consumption is reduced, but foreign substances and moisture may enter the server room

Engineering Contradiction:
Improveenergy consumptionVSAvoidforeign substances and moisture
Core Design Contradiction:
Use of energy by stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a demister filter as an intermediary component between the outer air inlet and the server room, which mediates the air flow by removing moisture and foreign substances while allowing cool air to pass through

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The demister filter uses porous material structure to physically separate and remove harmful particles and moisture droplets from the incoming outer air while maintaining air flow for cooling purposes

Inventive Principle:
Principle #31Porous materials

3Use of energy by stationary object

If simple outer air introduction is implemented, then energy consumption is reduced, but temperature and humidity control precision decreases

Engineering Contradiction:
Improveenergy consumptionVSAvoidtemperature and humidity control
Core Design Contradiction:
Use of energy by stationary objectVSMeasurement precision

Solution Approach 1:

The patent incorporates sensors that continuously monitor temperature and humidity levels in the server room, providing feedback to a control unit that adjusts the outer air intake and mist ejection accordingly to maintain precise environmental control

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system combines multiple functions including outer air introduction, mist ejection for humidity control, and active cooling into a single integrated device that can adaptively provide both cooling and humidification as needed

Inventive Principle:
Principle #6Universality (Multi-functionality)
