Engineering Contradiction Analysis
1Power
If multiple CPUs are arranged in series to improve computing speed, then computing capability is improved, but waste heat from upwind CPUs adversely affects downwind CPUs, reducing heat dissipation efficiency
Solution Approach 1:
The airflow channel is segmented into multiple independent channels using partition plates, with each CPU assigned to a separate channel. This segmentation prevents heat interference between CPUs while maintaining the series arrangement for improved computing capability.
Solution Approach 2:
The partition plates are arranged in different spatial dimensions (first partition plate in one dimension, second partition plate in another dimension), creating three-dimensional airflow separation. This multi-dimensional approach effectively isolates heat zones while preserving horizontal space for multiple CPUs.
2Area of stationary object
If horizontal space is limited, then device compactness is improved, but airflow guidance becomes difficult, decreasing heat dissipation efficiency
Solution Approach 1:
The invention utilizes vertical space by arranging partition plates in different dimensions, creating airflow separation without requiring additional horizontal space. This allows effective airflow guidance within limited horizontal footprint.
Solution Approach 2:
Multiple partition plates are nested within the same horizontal space, with the first and second partition plates positioned at different locations and orientations. This nested arrangement creates multiple airflow channels without expanding the horizontal footprint.
3Temperature
If heat dissipation devices are customized to improve heat dissipation efficiency, then cooling performance is improved, but manufacturing cost increases significantly
Solution Approach 1:
The heat dissipation device is segmented into standardized modular components (frame body, partition plates, flow guiding structures) that can be manufactured independently and assembled. This modularity enables mass production of standard parts, reducing customization costs.
Solution Approach 2:
The partition plates and flow guiding structures serve multiple functions: they separate airflow channels, guide wind flow, and prevent heat interference simultaneously. This multi-functionality reduces the number of specialized components needed, lowering manufacturing complexity and cost.
