Evaporative Induction Cooling for Data Center Heat Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data centers face significant energy consumption and costs due to the need for active cooling systems to manage the heat generated by thousands of microprocessors, which can lead to increased errors and failures.
Innovation Solution
An evaporative cooling system is implemented in data centers, utilizing misting nozzles to cool outside air through evaporation, which is then circulated to cool computer racks, potentially combined with supplemental cooling systems like chillers and heat exchangers, and controlled by a system monitoring temperature and humidity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional active cooling systems (chillers, condensers, pumps, fans, cooling towers) are used to remove heat from data centers, then heat removal effectiveness is improved, but energy consumption and operating costs increase significantly
Solution Approach 1:
The patent applies evaporative cooling by introducing water into the air stream, where it undergoes phase transition from liquid to vapor. This phase change absorbs heat from the air, cooling it naturally without requiring energy-intensive mechanical cooling systems. The water is introduced at specific locations in the air handling system to maximize evaporation and cooling effectiveness.
2Power
If more energy is consumed to operate cooling systems, then heat removal capability is improved, but operating costs increase
Solution Approach 1:
The evaporative cooling system uses the natural evaporation process to cool the air, requiring minimal external energy input. The system leverages the inherent thermodynamic properties of water evaporation to provide cooling, rather than relying on energy-consuming compressors and condensers. This self-service approach significantly reduces operating costs while maintaining effective heat removal.
3Use of energy by moving object
If heat is not adequately removed from data centers, then energy consumption is reduced, but microprocessor errors and failures increase
Solution Approach 1:
The system pre-cools the air stream before it reaches the computer equipment by introducing water into the air handling system upstream. This preliminary cooling action ensures that the air contacting the microprocessors is already at an optimal temperature, preventing overheating and associated errors or failures without requiring energy-intensive active cooling during operation.

This approach reduces energy consumption and costs while effectively managing heat, minimizing errors and failures in data center operations.
Implementation Method 1
multiple atomizers positioned upstream of the entry zone configured to spray atomized water into the circulating outside air. An evaporation zone is provided where the atomized water evaporates and cools the outside air to produce cooled air
Implementation Method 2
the air is cooled by the heat of evaporation in water or other liquids that may be evaporated into the airflow
Data Source
AI summary
A data center cooling system includes an evaporative cooling system. The evaporative cooling system includes fans configured to circulate outside air at ambient conditions through an entry zone of a data center, and atomizers positioned upstream of the entry zone configured to spray atomized water into the circulating outside air. The atomized water evaporates in an evaporation zone and cools the outside air to produce cooled air, which is directed through racks of computers positioned downstream of the evaporation zone.
