Solution Overview
Problem
Current battery cooling systems for hybrid and electric vehicles are inflexible, difficult to maintain, and inefficient due to complex constructions with numerous parts, leading to thermal inefficiencies and high costs, with no effective measure for preserving the battery in case of heat transfer liquid leakage.
Innovation Solution
A cooling module comprising a composite plate with a base plate of low thermal conductivity and a cover plate of high thermal conductivity, integrated with a network of channels and peripheral sealing, featuring a prominent and inclined lateral formation for fluid inlet and outlet conduits made in one piece with the base plate, optimizing heat exchange and reducing exposure and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If metallic solutions with distribution of heat transfer fluid by hoses to cooling plates are used, then heat exchange efficiency is improved, but device complexity and construction cost increase due to assembly of large number of parts
Solution Approach 1:
The patent merges the cooling plate and hose connections into a single integrated component. The cooling plate incorporates direct fluid distribution channels molded into its structure, eliminating the need for separate hoses and multiple sealed connections. This integration maintains effective heat exchange while dramatically reducing the number of parts and assembly steps.
Solution Approach 2:
The cooling plate serves multiple functions simultaneously: it acts as a thermal management component for heat exchange, a structural support element for battery modules, and an integrated fluid distribution system. The multi-functionality eliminates the need for separate hose assemblies and simplifies the overall cooling system architecture.
2Strength
If metallic housing is used for battery casing, then structural strength is improved, but thermal and electrical insulation capability deteriorates and corrosion resistance decreases
Solution Approach 1:
The patent employs composite material construction for the battery housing, combining materials with different properties to achieve optimal performance. The housing structure integrates materials that provide both structural strength and thermal/electrical insulation capabilities, eliminating the need for pure metallic construction while maintaining mechanical integrity.
3Ease of manufacture
If fixed structure battery units are used, then manufacturing simplicity is improved, but adaptability to different vehicle configurations deteriorates
Solution Approach 1:
The battery system is divided into modular battery modules that can be independently manufactured and then assembled in different configurations. Each module contains standardized components including the integrated cooling plate, allowing for simplified manufacturing of individual units while enabling flexible assembly to meet various vehicle space requirements and thermal management needs.
