Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling systems for electric vehicles are inadequate for effectively cooling various components beyond the engine and operator, as they rely on liquid cooling for engines and air cooling for operators, failing to address the cooling needs of additional electric vehicle components.
Innovation Solution
The implementation of an air cooling system within electric vehicles, which includes a compressor, condenser, and evaporator coil, directs cooled air through a first battery housing to efficiently cool a plurality of battery modules, with additional housings for electronic components and a second battery housing also receiving cooled air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional liquid cooling is used for engine components and air cooling for operators, then the cooling system is simple and cost-effective, but it cannot effectively cool additional electric vehicle components such as battery modules and electronic components
Solution Approach 1:
The air cooling system is designed to serve multiple cooling needs simultaneously - it cools battery modules, electronic components, and other EV-specific components through a unified cooling circuit that distributes cooled air via ducts to various housing units, making the system versatile for different cooling applications within the vehicle
2Reliability
If an air cooling system with compressor, condenser, and evaporator coil is implemented to cool battery modules and electronic components, then cooling effectiveness for EV components is improved, but the system complexity and space requirements increase
Solution Approach 1:
The cooling system is divided into segmented housing units (first battery housing, second battery housing, electronic component housing) that can be independently cooled through the distributed air cooling circuit, allowing for modular installation and maintenance while ensuring effective cooling of each component group
Solution Approach 2:
Ducts serve as intermediary channels that distribute cooled air from the central evaporator unit to various housing units throughout the vehicle, enabling efficient heat removal from multiple components without requiring direct connection to the cooling system for each component
