Use of an absorber material for absorbing and / or distributing liquids in an actively and / or passively cooled current-carrying system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current current-carrying systems, particularly battery systems, face challenges in effectively managing water vapor and liquid condensation, leading to potential short circuits and corrosion, with existing desiccants and superabsorbers causing issues like gel blocking, dust formation, and uncontrolled swelling.
Innovation Solution
A segmented casing with superabsorbent particles arranged in pockets connected by seams allows for controlled absorption and distribution of liquids, preventing gel blocking and reducing dust formation, while maintaining high absorption capacity and thermal stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If desiccants are used to absorb water vapor, then water vapor is removed from the housing, but the desiccants also absorb liquid water and function as moisture siphons, drawing water vapor into the housing
Solution Approach 1:
The absorber material is divided into multiple pockets separated by seams, creating segmented absorption zones. This segmentation prevents the formation of continuous liquid pathways while maintaining high absorption capacity for liquid water that enters the housing.
Solution Approach 2:
The absorber material is placed specifically at the lowest point of the housing where liquid condensate accumulates, rather than distributing it throughout. This local placement targets the actual liquid water problem without creating moisture siphon effects that would draw vapor from elsewhere.
2Quantity of substance
If superabsorbers are used to absorb liquid water, then high absorption capacity is achieved, but the superabsorbers swell and block transport channels, preventing further absorption
Solution Approach 1:
The absorber material is divided into multiple pockets separated by seams, creating segmented absorption zones. This segmentation prevents the formation of continuous liquid pathways while maintaining high absorption capacity for liquid water that enters the housing.
Solution Approach 2:
The invention moves the absorber material from a two-dimensional film structure to a three-dimensional volumetric structure with pockets. This dimensional change provides internal capacity for swelling without blocking external transport channels, as liquid can enter through the seams and distribute throughout the pocket volume.
3Quantity of substance
If superabsorbers are used to absorb liquid water, then high absorption capacity is achieved, but uncontrolled swelling causes mechanical pressure and electrical short circuits
Solution Approach 1:
The absorber material is divided into multiple pockets separated by seams, creating segmented absorption zones. This segmentation prevents the formation of continuous liquid pathways while maintaining high absorption capacity for liquid water that enters the housing.
Solution Approach 2:
The pockets are formed with flexible casings that can accommodate the swelling of superabsorber material internally while containing the mechanical pressure. This allows the superabsorbers to swell freely within each pocket without exerting uncontrolled pressure on surrounding electronic components.
4Object-affected harmful factors
If desiccants are used to absorb water, then water absorption is achieved, but the desiccants form dust and are electrically conductive in moist state, causing short circuits
Solution Approach 1:
The invention uses superabsorber polymers that form gel structures upon water absorption rather than traditional crystalline desiccants. This composite gel material does not produce dust and has different electrical conductivity characteristics, reducing the risk of short circuits while maintaining high water absorption capacity.
