Methods and system for a degas bottle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coolant systems face challenges in efficiently managing multiple cooling circuits with different operating temperatures, as traditional degas bottles and reservoirs require multiple fill points and can lead to coolant mixing and reduced cooling efficiency due to packaging constraints and thermal issues.
Innovation Solution
A combined reservoir and degas bottle system with a vertically arranged reservoir chamber and separate degas chambers, where a dividing wall thermally insulates each chamber and a transverse wall below the minimum fill line allows coolant flow and gas exchange, maintaining separate coolant temperatures and efficient filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wall is arranged within an expansion tank to divide the tank into separate chambers for different coolant circuits, then coolant mixing is prevented and thermal insulation is improved, but filling efficiency is reduced and packaging space is wasted
Solution Approach 1:
The patent transitions from horizontal chamber separation to vertical stratification. The expansion tank is divided into an upper air chamber and a lower coolant chamber separated by a transverse partition, allowing gravity-driven filling from a single point while maintaining circuit separation through side walls. This dimensional reorganization resolves the contradiction by enabling efficient top-down filling without compromising coolant separation.
2Temperature
If the dividing wall is extended to a location above the minimum fill line to improve thermal insulation, then heat transfer between chambers is reduced, but filling efficiency is blocked and coolant volume cannot be maintained
Solution Approach 1:
The patent applies different wall heights in different spatial locations. The transverse partition is positioned at the minimum fill line to enable filling, while the side walls extend upward to provide thermal insulation where needed. This localized differentiation resolves the contradiction by providing insulation only in the lateral direction rather than extending the full height of the dividing structure.
3Temperature
If multiple combined coolant reservoirs and degas bottles are used for different cooling circuits, then thermal insulation between circuits is improved, but packaging space increases and system complexity increases
Solution Approach 1:
The patent combines multiple coolant circuits into a single expansion tank with vertical stratification. The transverse partition creates distinct upper and lower chambers that can serve different circuits while sharing the same physical housing. This merging approach reduces packaging space and system complexity while maintaining thermal insulation through the partition design.
4Volume of stationary object
If a single housing with multiple chambers is used to reduce packaging space, then packaging efficiency is improved, but filling efficiency is reduced due to blocked filling paths
Solution Approach 1:
The patent segments the expansion tank into vertically arranged chambers separated by a transverse partition at the minimum fill line. This segmentation allows each chamber to be independently filled from the top without blocking paths, as the partition only extends to the minimum fill line level. The segmentation maintains compact packaging while preserving efficient filling capability.

Function Achieved in This Case
This configuration enables efficient deaeration, reduces packaging space and manufacturing costs, and maintains desired coolant volumes while preventing coolant mixing, thus improving cooling efficiency and reducing service time.
Implementation Method 1
the transverse wall comprising apertures configured to flow coolant from the reservoir to the first and second chambers
Implementation Method 2
the dividing wall also thermally insulates the first chamber from the second chamber such that the first chamber may receive coolant from a first coolant circuit comprising a first coolant temperature and the second chamber may receive coolant from a second coolant circuit comprising a second coolant temperature, different than the first coolant temperature

AI summary
Methods and systems are provided for a cooling system. In one example, a system comprising a housing comprising a first chamber fluidly coupled to a first cooling circuit and a second chamber fluidly coupled to a second cooling circuit. A reservoir is arranged vertically above each of the first chamber and the second chamber within the housing. A transverse wall fluidly separates the reservoir from the first and second chambers and a dividing wall physically coupled to the transverse wall, separates the first and second chambers from one another. Each of the transverse wall, dividing wall, first chamber, and the second chamber are arranged vertically below a minimum fill line of the reservoir.
