Thermally Coupled Power Converter Layout for Compact Drive Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The size of power conversion devices is increased due to the structural separation and separate cooling of battery modules and power converters, which are thermally interfered with each other, leading to increased heat generation and size.
Innovation Solution
A power conversion device with an integrated thermal coupling member that thermally couples all-solid-state batteries and power converters, using a single cooling device to manage operating temperatures, thereby reducing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the battery module and power converter are structurally separated and cooled by different cooling devices, then the operating temperatures are controlled within rated limits, but the device size increases
Solution Approach 1:
The patent merges the battery module and power converter into a single integrated housing structure, allowing both components to share the same thermal management system. The housing contains both the battery module and power converter, enabling unified cooling approach that reduces overall device size while maintaining temperature control for both components.
2Volume of stationary object
If the battery module and power converter are integrated with thermal coupling, then the device size is reduced, but thermal interference between components occurs
Solution Approach 1:
The patent segments the housing into distinct regions: a first housing portion for the battery module and a second housing portion for the power converter. This spatial segmentation allows thermal coupling for size reduction while maintaining separate zones that can be independently managed to minimize thermal interference between the two components.
