Integrated Air-Drying Cartridge for EV Coolant Reservoirs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for electric vehicle batteries face challenges in maintaining optimal temperature efficiency, preventing water and dirt contamination, and avoiding the escape of volatile hydrocarbons, particularly due to volume fluctuations and the need for separate and complexly controlled drying and adsorber devices.
Innovation Solution
A removable cartridge integrating a filter device, a drying device, and a hydrocarbon adsorber device, with coaxial flow paths and non-return valves, simplifies maintenance by allowing easy integration and replacement, ensuring effective air cleaning, water reduction, and hydrocarbon absorption, while preventing environmental contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate drying devices and adsorber devices are mounted on the expansion tank, then the coolant can be protected from water and hydrocarbon contamination, but the device complexity and control requirements increase significantly
Solution Approach 1:
The patent combines the drying device and hydrocarbon adsorber device into a single integrated cartridge assembly that attaches to the expansion tank. This merging of previously separate components reduces system complexity while maintaining the protective functions against both water and hydrocarbon contamination.
Solution Approach 2:
The integrated cartridge serves multiple functions simultaneously: it acts as both a drying device for water removal and a hydrocarbon adsorber device for volatile component capture. This multi-functionality eliminates the need for separate controlled systems for each protection function.
2Reliability
If multiple separate devices are used for filtering, drying, and adsorbing, then comprehensive protection is achieved, but maintenance difficulty and cost increase
Solution Approach 1:
By consolidating the filter device, drying device, and hydrocarbon adsorber device into one replaceable cartridge, the system enables simplified maintenance. The entire assembly can be removed and replaced as a single unit, eliminating the need for complex disassembly and individual component servicing.
3Reliability
If the cartridge is designed with multiple flow paths and components, then effective cleaning and adsorption are achieved, but the manufacturing complexity increases
Solution Approach 1:
The patent employs a nested arrangement where the filter device, drying device, and hydrocarbon adsorber device are positioned concentrically within the cartridge housing. This nested configuration allows multiple functional components to be manufactured and assembled in a standardized, space-efficient manner that reduces overall manufacturing complexity.
