Dual-Chamber Vortex Degassing Device for Thermal Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vortex separation devices for motor vehicle heat transfer circuits are not optimized for high fluid flow rates and fail to effectively isolate independent circuits, leading to inefficient heat exchange between circuits operating at different temperatures.
Innovation Solution
A dual-chamber vortex degassing device with separate inlets and outlets for each chamber, where the second outlet extends upwards along the axis to prevent bubble carryover and minimize flow exchanges between chambers, allowing independent operation at different temperatures and efficient separation at high flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single vortex separation device is used for two circuits, then device complexity is reduced, but heat exchange between circuits operating at different temperatures cannot be effectively prevented
Solution Approach 1:
The device is divided into two separate chambers (first chamber for first circuit, second chamber for second circuit) that are physically isolated from each other. Each chamber has its own deflector, inlets, and outlets, preventing fluid mixing and heat exchange between circuits while operating at different temperatures. This segmentation resolves the contradiction by maintaining thermal isolation without requiring completely separate devices.
2Device complexity
If the second outlet is positioned at the chamber level, then device structure is simplified, but gas bubbles from the first chamber are carried into the second chamber
Solution Approach 1:
The second outlet is extended vertically along the axis A to a position above the first chamber level, utilizing the vertical dimension to create physical separation between the gas outlet of the first chamber and the second chamber. This dimensional extension prevents gas bubbles from the first chamber from being carried into the second chamber while maintaining a compact overall structure.
3Volume of moving object
If chambers are closely positioned to reduce device size, then compactness is improved, but flow exchanges and heat exchanges between chambers increase
Solution Approach 1:
The gas outlet path of the first chamber is extracted and extended vertically to pass through or above the second chamber without making fluid contact. This extraction creates a physical barrier that prevents flow exchanges and heat exchanges between chambers while maintaining close positioning for compactness. The gas outlet acts as a structural element that provides thermal isolation.

Function Achieved in This Case
The device effectively separates liquid and gaseous fractions at high flow rates while preventing heat exchange between independent sub-circuits, enabling them to operate at different temperatures, thus optimizing the performance of the fluid transfer circuit.
Implementation Method 1
The centrifugal effect of the vortex allows to separate the liquid fraction radially outwards (with respect to the axis A) and the gaseous fraction radially inwards by density difference
Implementation Method 2
the fluid arriving through the inlet is rotated around an axis A in the chamber to form a vortex for separating liquid and gaseous fractions
