Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power source apparatuses face challenges in maintaining even cooling of batteries due to irregular air flow distribution caused by deformed chassis shapes and inefficient heat management, leading to uneven cooling and reduced cooling efficiency.
Innovation Solution
The power source apparatus incorporates a diffusing portion and a heat-insulating portion to manage air flow and heat exchange, ensuring homogeneous air distribution and reducing heat conduction between the air and inner wall surfaces, thereby maintaining even battery cooling and improving cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chassis shape is deformed to accommodate installation restrictions, then the adaptability of the power source apparatus is improved, but the air flow distribution becomes uneven and cooling performance deteriorates
Solution Approach 1:
The patent applies local quality by creating a diffusing portion with a specific expanded space at the blowing side of the air introduction path. This localized structural modification ensures that air flow is homogenized precisely where needed (at the battery cooling surfaces) without requiring the entire chassis to maintain a regular shape, thus resolving the contradiction between adaptability to installation restrictions and cooling performance.
2Loss of energy
If a heat-insulating cover is attached to the outside portion of the chassis, then heat insulation performance is improved, but the air flow becomes uneven and cooling efficiency deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the chassis into distinct functional zones: a heat-insulating portion for thermal isolation and a diffusing portion with expanded space for air flow homogenization. This segmentation allows the heat-insulating cover to provide thermal protection while the separately designed diffusing portion ensures uniform air distribution to batteries, resolving the contradiction between heat insulation performance and cooling efficiency.
3Temperature
If the blower is arranged on the center of the lower portion of the chassis, then the air flow is easily homogenized and cooling performance is improved, but the device complexity increases when additional diffusing portions are added
Solution Approach 1:
The patent applies merging by integrating the diffusing portion directly into the air introduction path structure of the chassis, rather than adding it as a separate component. The expanded space is formed as part of the chassis geometry itself, combining the structural support function with the air flow diffusion function, thus improving cooling performance while minimizing increases in device complexity.
