Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data centers, the inefficient mixing of cold and warm air due to arbitrary airflow patterns in legacy systems leads to suboptimal climate control, resulting in excessive power consumption and temperature regulation issues within racks.
Innovation Solution
A climate control system for racks that utilizes a duct with a double bottom configuration to direct cooled air from below and remove heated air above, incorporating sensors and conveyors to manage airflow and temperature, with a master control unit to optimize cooling based on real-time parameters and sensor data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If generalized cooling is applied to the complete room to handle hotspots, then temperature limits are maintained, but power consumption increases
Solution Approach 1:
The patent implements local climate control by equipping individual racks with climate control units rather than cooling the entire room. Each rack independently regulates its temperature, allowing targeted cooling only where heat is generated by electronic devices, thereby avoiding the energy waste of cooling unaffected areas.
Solution Approach 2:
The climate control system is segmented into independent rack-level units rather than a centralized room-level system. Each rack operates autonomously with its own climate control unit, enabling distributed temperature management that reduces overall energy consumption by addressing only the specific thermal needs of each rack.
2Quantity of substance
If electronic devices are packed tightly in racks, then space utilization increases, but cooling efficiency decreases
Solution Approach 1:
The patent introduces a vertical airflow dimension by positioning climate control units at the bottom of racks to supply cool air upward through device intakes. This vertical cooling approach complements the horizontal packing of devices, enabling high device density while maintaining effective heat removal through the added vertical airflow path.
Solution Approach 2:
The climate control system provides localized cooling directly at the device level within tightly packed racks. Each rack's climate control unit delivers cooled air precisely where electronic devices need it, maintaining cooling efficiency even when devices are densely arranged without requiring additional spacing for airflow.
3Adaptability or versatility
If arbitrary airflow patterns are used in legacy systems, then system compatibility is maintained, but climate control efficiency deteriorates
Solution Approach 1:
The patent implements dynamic airflow control within racks by using climate control units that actively manage air circulation patterns. The system adapts airflow delivery to match the thermal characteristics of devices in each rack, creating organized vertical flow patterns that improve climate control efficiency while maintaining compatibility with diverse legacy equipment that may have varying air intake requirements.

AI summary
A system and method for cooling a rack is provided. The system comprises a constellation of racks that form an aisle between them and all cooling air supply sides of all racks face the aisle. The aisle is covered on top and at both ends against leaking air. Cooling air enters the aisle from below. In a method for controlling a temperature inside a rack, cooling air of a fixed temperature is advanced towards the cooling air supply side of the racks and it is determined, whether a turnover of cooling air through the rack corresponds to a turnover of cooling air through a conveyor, which delivers the cooling air towards the rack.
