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, which adversely affect the performance and reliability of electronic 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 configuring them parallel to heat-generating equipment, and a frame assembly that accommodates varying numbers of equipment units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If in-row cooling equipment is used to cool electronic equipment, then heat management effectiveness is improved, but space requirements increase making it difficult to implement in prefabricated power modules
Solution Approach 1:
The partition assembly is nested within the existing rack structure, with cooling channels integrated into the partition itself rather than requiring separate cooling equipment. The hot air containment channels are formed within the partition walls, allowing the cooling function to be embedded in the structural component already present in the limited space.
Solution Approach 2:
The partition assembly creates vertical and horizontal separation of airflows using multiple dimensions - dividing cold and hot air paths in both vertical and horizontal planes. The partition includes openings at different heights and positions to manage airflow in three-dimensional space, maximizing cooling efficiency within the constrained footprint.
2Ease of operation
If partition assemblies with multiple openings are used for service access and hot air passage, then ease of operation and maintenance is improved, but structural complexity increases
Solution Approach 1:
The partition assembly serves multiple functions simultaneously: it provides structural support for the rack, creates hot air containment channels, provides service access openings, and integrates cooling pathways. The same partition structure performs both structural and thermal management functions, reducing the need for additional separate components.
Solution Approach 2:
The partition assembly is divided into modular sections with standardized opening configurations. Each partition unit can be independently configured with specific opening patterns based on service requirements, allowing flexibility without increasing overall system complexity. The segmented design enables easy assembly and maintenance.
3Manufacturing precision
If blanking panels are used to block openings, then airflow control precision is improved, but device complexity increases
Solution Approach 1:
The blanking panels are designed to be removable and reconfigurable, allowing the airflow paths to be dynamically adjusted based on operational requirements. Panels can be installed or removed without permanent modifications, enabling flexible adaptation to different service scenarios while maintaining simple overall structure.
