Battery Pack Cooling Pipe Flange for Simpler Sealing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting process between a flange and a box in battery packs is complicated due to the need for multiple flanges and separate sealing of connecting pipes, which complicates the assembly and reduces sealing reliability.
Innovation Solution
A battery pack design where a single flange spans both the first and second connecting pipes, with a sealing ring enclosing both pipes, simplifying the mounting process and improving sealing reliability by reducing the number of flanges and separate sealing points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple flanges are used to connect separate connecting pipes to the box, then each connecting pipe can be individually sealed and connected, but the mounting process becomes complicated and the number of sealing points increases
Solution Approach 1:
The patent merges multiple flanges into a single integrated flange structure that spans across multiple connecting pipes. This single flange includes multiple flange bodies connected through connection portions, allowing all connecting pipes to be sealed and connected to the box through one unified mounting operation rather than multiple separate flange installations.
Solution Approach 2:
The single flange structure performs multiple functions simultaneously: it provides sealing surfaces for multiple connecting pipes, structural support for the thermal management component, and a unified mounting interface to the box. This multi-functional design eliminates the need for separate flanges for each connecting pipe while maintaining reliable sealing for all fluid pathways.
2Reliability
If multiple separate flanges and sealing rings are used for each connecting pipe, then each connection can be independently sealed, but the number of leakage positions increases and sealing reliability decreases
Solution Approach 1:
The patent combines multiple sealing functions into a single sealing ring that seals against the single integrated flange. This reduces the number of sealing interfaces from multiple separate flange-box connections to one unified sealing position, thereby reducing the total number of potential leakage points while maintaining comprehensive sealing coverage for all connecting pipes.
Solution Approach 2:
Instead of having multiple separate sealing points that each pose a potential leakage risk, the design consolidates all sealing requirements into a single sealing ring interface. This transformation converts the harmful effect of multiple leakage points into a beneficial single-point sealing system that is easier to control and more reliable.
3Ease of operation
If multiple flanges are mounted on the box for separate connecting pipes, then each pipe can be connected, but the mounting process requires multiple steps and becomes time-consuming
Solution Approach 1:
The patent merges the mounting operations for multiple connecting pipes into a single mounting action. The single integrated flange structure allows all connecting pipes to be attached to the box simultaneously through one mounting process, eliminating the need for multiple separate mounting steps and significantly improving assembly efficiency.
Solution Approach 2:
The flange structure is pre-designed and pre-assembled as a single integrated component before installation on the box. The connection portions between flange bodies are already formed, so during installation, the entire multi-pipe connection system is mounted in one operation rather than requiring sequential assembly of individual flanges and pipes.
