Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inverter cooling structures are inefficient due to the generation of eddy currents and reduced heat radiation effects caused by parallel inlet and outlet arrangements, leading to increased size and heat management challenges.
Innovation Solution
The proposed apparatus optimizes heat radiation by dividing the internal space of the inverter housing with extended walls to create distinct flow paths for air, allowing for controlled airflow and heat dissipation based on the heat generation of electric elements, with adjustable openings and fan placement to enhance cooling efficiency.

Engineering Contradiction Analysis
1Volume of moving object
If the inlet and outlet are arranged in parallel to cool semiconductor devices, then the cooling structure is compact, but an eddy current is generated due to separation of space at the inlet which reduces heat radiation effect
Solution Approach 1:
The housing internal space is segmented into multiple flow paths using partition walls. The first partition wall extends from the inlet to divide the inner space, and the second partition wall extends from the outlet to divide the inner space, creating first and second flow paths. This segmentation eliminates eddy currents by providing distinct airflow channels while maintaining a compact inverter structure.
Solution Approach 2:
Different regions of the housing are assigned different functions through localized structural modifications. Electric elements are selectively disposed on specific flow paths based on their heat generation characteristics, and partition walls are positioned to optimize airflow distribution to specific areas, ensuring efficient heat radiation from high-heat elements while maintaining overall compactness.
2Loss of energy
If a relatively large fan and heat radiating member are used for forcibly discharging heat, then heat dissipation is improved, but the size of the inverter increases
Solution Approach 1:
The cooling system is segmented into multiple independent flow paths, allowing optimized airflow distribution. This enables the use of smaller fans since the airflow is more efficiently directed through partitioned channels, improving heat dissipation without requiring oversized cooling components.
Solution Approach 2:
The partition walls are arranged in different spatial orientations (first wall from inlet, second wall from outlet) to create three-dimensional airflow patterns. This dimensional arrangement optimizes heat radiation efficiency within the available space, reducing the need for larger heat radiating members.
3Loss of energy
If partition walls are added to create distinct flow paths, then heat radiation effect is optimized, but device complexity increases
Solution Approach 1:
The housing is segmented using partition walls that extend from the inlet and outlet respectively, creating defined flow paths. This segmentation optimizes heat radiation by directing airflow efficiently while maintaining structural simplicity through the use of straightforward partition geometry rather than complex cooling channels.
Solution Approach 2:
The partition walls serve multiple functions: they divide the housing into flow paths, support electric elements, and guide airflow. This multi-functionality reduces the need for additional separate components, thereby optimizing heat radiation without proportionally increasing device complexity.
