Engineering Contradiction Analysis
1Temperature
If a cooling structure is implemented for heating elements, then heat dissipation performance is improved, but device complexity increases due to the need for additional cooling components and flow path integration
Solution Approach 1:
The cooling device is integrated with the power converter housing, merging the cooling function into the existing structural component. The housing serves dual purposes as both protective enclosure and cooling structure, eliminating the need for separate cooling components and reducing overall device complexity.
Solution Approach 2:
The power converter housing is designed to perform multiple functions: mechanical protection of internal components and heat dissipation through integrated cooling channels. This multi-functionality reduces the total number of components needed while achieving effective cooling of the heating elements.
2Loss of energy
If cooling water flow paths are added to cool heating elements, then heat exchange efficiency is improved, but device complexity increases due to additional flow paths and cooling components
Solution Approach 1:
The cooling water flow paths are embedded within the power converter housing structure, merging the heat exchange function with the existing mechanical housing. This integration allows efficient heat removal from heating elements without adding separate cooling components or complex external flow path systems.
