Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cooling systems in data centers face inefficiencies in airflow management, leading to overheating and power wastage due to the inability to dynamically direct airflow to specific components based on their utilization rates and temperatures, and failure to account for removed components, resulting in inefficient heat dissipation and resource waste.
Innovation Solution
A system comprising a fan module, a deflection member, and a chassis management controller (CMC) that utilizes an artificial neural network (ANN) to dynamically control the engagement angle of the deflection member and airflow rate, directing airflow to system components based on their utilization rates, temperatures, and installation status, and adjusts fan speed using Pulse Width Modulation (PWM) signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If airflow is directed to all components uniformly, then all components receive cooling, but energy is wasted on components with low utilization rates
Solution Approach 1:
The patent implements dynamic airflow control by making the deflection member movable and adjustable based on real-time component utilization rates. The system continuously monitors component status and dynamically redirects airflow to high-utilization components while reducing flow to low-utilization components, resolving the contradiction between uniform cooling and energy efficiency.
Solution Approach 2:
The system changes the engagement angle parameter of the deflection member to redirect airflow dynamically. By adjusting this geometric parameter based on component utilization rates, the system optimizes cooling efficiency and reduces energy waste on idle components.
2Temperature
If airflow rate is increased to improve heat dissipation, then cooling performance improves, but power consumption increases
Solution Approach 1:
The patent applies local quality by directing airflow selectively to specific components based on their individual thermal needs and utilization rates. Instead of uniformly increasing airflow to all components, the system concentrates cooling capacity where it is most needed, improving heat dissipation efficiency without proportionally increasing overall power consumption.
Solution Approach 2:
The system monitors component status and autonomously adjusts airflow distribution without external intervention. Components with high utilization rates automatically receive more airflow, while idle components receive less, allowing the system to self-optimize cooling efficiency and energy consumption.
3Stability of the object's composition
If airflow is maintained to removed components, then airflow path remains stable, but resources are wasted on non-installed components
Solution Approach 1:
The system continuously monitors component installation status and provides feedback to the airflow control mechanism. When a component is removed or becomes inactive, the system detects this change and adjusts the deflection member to redirect airflow away from the removed component, eliminating resource waste while maintaining stable airflow paths to active components.
