Tapered Gas-Liquid Separator for Vehicle Coolant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-liquid separators in vehicles have low separation performance and spatial inefficiencies due to their reliance on gravity separation, leading to unstable air bubble separation and potential re-mixing with coolant, and are often externally mounted, increasing spatial limitations.
Innovation Solution
A gas-liquid separation device with a tapered cylindrical structure and symmetrical design, featuring tangential fluid introduction and separate gas and liquid discharge pipes, enhances separation efficiency by utilizing centrifugal force to separate and maintain the separation of air bubbles from coolant, minimizing re-mixing and spatial requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gas-liquid separator uses gravity-based natural separation, then the structure is simple, but the gas-liquid separation performance is low and air bubbles may re-mix with coolant
Solution Approach 1:
The separator introduces a swirling flow mechanism that dynamically separates gas and liquid phases through centrifugal force generated by tangential inlet design. The coolant enters through tangential nozzles creating a vortex flow, causing gas bubbles to move outward to the wall while liquid flows downward, achieving reliable separation without complex mechanical components
Solution Approach 2:
The invention utilizes fluid dynamics and hydrocyclone principles where the coolant flow itself generates the separating force. The swirling liquid flow creates a centrifugal field that automatically separates gas bubbles from liquid without external mechanical intervention, maintaining simplicity while improving separation performance
2Reliability
If a gas-liquid separator is mounted externally to the reservoir tank, then the separation function is added, but the spatial limitation of the reservoir tank is increased
Solution Approach 1:
The gas-liquid separator is integrated directly into the reservoir tank by utilizing the tank wall as the separator wall. The tangential nozzles are mounted on the reservoir tank wall, and the swirling flow occurs within the tank's existing volume, merging the storage and separation functions into a single compact unit that eliminates external mounting requirements
