Integrated Fluid Channel in Reducing Agent Tank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reducing agent tanks for motor vehicles lack an integrated and efficient heating solution that is both compact and effectively integrated into the tank design, which can impact the performance of exhaust gas cleaning systems.
Innovation Solution
A reducing agent tank with a tank segment that incorporates a molded-in fluid channel for heating, where the tank segment itself forms the fluid channel, allowing for efficient heat distribution and integration with the vehicle's cooling circuit, and includes a delivery module for pumping the reducing agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate heating pipes or hoses are used to heat the reducing agent, then the heating function can be achieved, but the device complexity increases and space is wasted
Solution Approach 1:
The heating system is merged with the tank structure by integrating fluid channels directly into the tank segment. The tank segment itself forms the fluid channel, eliminating the need for separate heating pipes or hoses. This combining of functions reduces device complexity while maintaining effective heating capability.
2Temperature
If external heating elements are added to the tank, then heating capability is provided, but the tank design becomes more complex and compactness is reduced
Solution Approach 1:
The fluid channel is nested within the tank segment structure itself. The channel is formed as an integrated part of the tank segment, allowing the heating system to be contained within the existing tank volume without requiring additional external space or increasing overall tank size.
3Temperature
If multiple separate components are used for heating, then heating function is achieved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The tank segment and fluid channel are merged into a single integrated component formed by one and the same molded part. This eliminates the need for separate manufacturing of heating pipes and their subsequent assembly to the tank, significantly simplifying both manufacturing processes and assembly operations.
