Power Module Airflow Partition for In-Row Cooling Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In prefabricated power modules, limited space makes it difficult to use in-row cooling equipment effectively, leading to heat build-up and hot spots due to heat-generating equipment.
Innovation Solution
A hot air containment system with a service access partition assembly that includes multiple openings for access and hot air passage, allowing for the use of in-row cooling units by directing hot air from heat-generating equipment to cooling units, and a modular design that accommodates varying numbers of equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If in-row cooling equipment is used to cool heat-generating equipment, then cooling efficiency is improved, but space requirements increase which is not feasible in prefabricated power modules
Solution Approach 1:
The partition assembly is nested within the existing rack structure, with partitions extending between racks to create contained airflow paths without requiring separate dedicated cooling spaces. The cooling units are integrated into the available space between equipment rather than requiring additional external space.
Solution Approach 2:
The partition assembly utilizes the vertical dimension by extending partitions from the floor to overhead structures, creating three-dimensional airflow containment zones. This allows cooling to be effective in the vertical space already available within the rack enclosure rather than requiring additional horizontal space.
2Temperature
If partition assemblies are used to direct airflow, then cooling effectiveness is improved, but access to equipment becomes more difficult
Solution Approach 1:
The partition assembly is divided into multiple modular sections that can be independently configured and accessed. Service access partitions are positioned at specific intervals to allow technicians to reach equipment without removing entire partition structures, maintaining airflow containment while providing necessary access points.
Solution Approach 2:
The partition assembly incorporates movable or removable components that can be dynamically adjusted based on maintenance needs. Service access partitions can be temporarily repositioned or removed to allow equipment access, then restored to maintain airflow containment during operation.
3Ease of repair
If service access partitions are added to allow equipment access, then ease of maintenance is improved, but airflow containment is compromised
Solution Approach 1:
The partition assembly implements different partition densities in different locations - solid continuous partitions in areas requiring strict airflow containment, and localized service access partitions with openings or gaps only where equipment access is needed. This maintains overall airflow containment while providing targeted access points for maintenance.
