Evaporative induction cooling system for a data center
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 air-to-air heat exchangers and supplemental cooling systems to maintain optimal 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 the heat generated by microprocessors can be effectively removed, but the energy consumption and operating costs increase significantly
Solution Approach 1:
The patent utilizes evaporative cooling where water undergoes phase transition from liquid to vapor, absorbing heat from the air in the process. This natural phase change provides cooling without requiring energy-intensive mechanical refrigeration systems, directly addressing the contradiction between effective heat removal and high energy consumption
Solution Approach 2:
The invention extracts and removes the most energy-intensive components (chillers, condensers, pumps, cooling towers) from the cooling system, retaining only essential elements like fans and evaporative cooling media. This extraction eliminates the majority of energy consumption while maintaining heat removal capability
2Power
If thousands of microprocessors operate at high speed, then computational power is improved, but the heat generation increases requiring more energy for cooling
Solution Approach 1:
The patent converts the harmful heat generated by microprocessors into a beneficial cooling mechanism by using evaporative cooling. The heat that would otherwise require energy-intensive removal is instead utilized to drive the evaporation process, which naturally absorbs heat and cools the environment without additional energy input
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces energy consumption and costs by effectively managing heat without the high energy demands of traditional cooling methods, while minimizing equipment failures and improving operational efficiency.
Implementation Method 1
An evaporation zone is provided where the atomized water evaporates and cools the outside air to produce cooled air
Implementation Method 2
outdoor air may be circulated past the misting nozzles, so that 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.
