Battery Pack Cooler Layout for Shared Junction Box Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power battery packs require a dedicated cooler for cooling the junction box, which is inefficient and adds complexity.
Innovation Solution
A power storage device design where a single cooler is in thermal contact with both the power storage cells and the junction box, eliminating the need for a dedicated cooler for the junction box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a dedicated cooler is provided for cooling the junction box, then the junction box cooling function is improved, but the device complexity increases
Solution Approach 1:
The patent merges the cooling functions for power storage cells and junction box into a single cooler. The cooler is configured with a first cooling portion that contacts the power storage cells and a second cooling portion that contacts the junction box, allowing one cooler to perform both cooling tasks simultaneously, thus reducing device complexity while maintaining effective cooling.
Solution Approach 2:
The single cooler is designed to serve multiple functions: it cools both the power storage cells and the junction box. This multi-functional design eliminates the need for separate dedicated coolers, reducing the overall number of components and simplifying the thermal management system while ensuring both components are adequately cooled.
2Temperature
If multiple separate coolers are used for power storage cells and junction box, then cooling effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple cooling functions into a single integrated cooler structure. By merging the cooling of power storage cells and junction box into one component, the manufacturing process is simplified, material costs are reduced, and assembly operations are decreased, thereby lowering overall manufacturing costs while maintaining effective cooling performance.
Solution Approach 2:
The single cooler is designed with multi-functional capability to cool both power storage cells and junction box. This universal design reduces the total number of parts that need to be manufactured, inventoried, and assembled, leading to significant cost savings in manufacturing while ensuring adequate cooling effectiveness for all thermal management requirements.
