Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valves used in eco-friendly vehicles fail to manage cooling water temperatures effectively, leading to heat interference between cooling media of different temperatures, which can degrade the operating efficiency of battery systems.
Innovation Solution
A heat interference prevention valve with multiple flow paths and a heat interference prevention part, such as an empty space or material with low thermal conductivity, is designed to isolate these paths and minimize heat exchange between cooling media, ensuring efficient temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cooling water of different temperatures circulates through an integrated valve, then the valve can control multiple heat management parts, but heat interference occurs between cooling media causing temperature management failure
Solution Approach 1:
The valve body is divided into multiple independent flow paths with separate circulation holes for different heat management parts. Each flow path is isolated by partitions, allowing independent temperature control for battery cooling (30°C) and PE parts cooling (70°C) without heat interference between paths.
2Temperature
If multiple flow paths are formed in the valve, then temperature control for different parts is improved, but the valve structure becomes more complex
Solution Approach 1:
Multiple flow paths and circulation holes are integrated into a single valve body structure. The valve combines multiple functions (controlling cooling water flow to battery, PE parts, and other heat management components) in one unified component, reducing the need for multiple separate valves while maintaining temperature control capability.
3Loss of energy
If cooling media of different temperatures exchange heat in the valve, then heat recovery might occur, but the cooling effectiveness for temperature-sensitive components deteriorates
Solution Approach 1:
The valve partitions cooling water flow paths using internal partitions and separate circulation holes, preventing thermal mixing between hot (70°C) and cold (30°C) cooling media. This ensures that temperature-sensitive battery cooling maintains its effectiveness while allowing heat recovery in dedicated paths where appropriate.
