Integrated Reservoir Tank Assembly for Vehicle Cooling Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In eco-friendly vehicles, the number of reservoir tanks in water cooling systems is increased, leading to higher material costs, weight, and complexity in space layout, which complicates installation and reduces productivity due to the need for separate tanks for different cooling circuits with varying temperature requirements.
Innovation Solution
An integrated reservoir tank assembly is designed, where the inner space is partitioned into multiple chambers for different cooling circuits, with integrated electric water pumps for each circuit, reducing the number of parts and simplifying installation while maintaining separate temperature management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If separate reservoir tanks are used for different cooling circuits, then temperature management for each circuit is improved, but the number of parts and material cost increase
Solution Approach 1:
The reservoir tank is divided into multiple separate chambers (first chamber, second chamber, third chamber) that are isolated from each other by partition walls. Each chamber independently stores cooling water for a specific cooling circuit, enabling separate temperature management while being contained within a single integrated tank structure.
Solution Approach 2:
The single reservoir tank structure serves multiple functions by accommodating different cooling circuits with different temperature requirements. The tank body acts as a universal container that simultaneously manages multiple cooling systems, reducing the total number of separate tanks needed.
2Temperature
If separate reservoir tanks are used for different cooling circuits, then temperature management for each circuit is improved, but weight increases
Solution Approach 1:
Multiple separate reservoir tanks for different cooling circuits are merged into a single integrated reservoir tank structure. The tank body combines multiple chambers that would otherwise require separate tank units, reducing the total weight while maintaining separate temperature management capabilities through internal partitioning.
3Temperature
If separate reservoir tanks are used for different cooling circuits, then temperature management for each circuit is improved, but installation space and layout complexity increase
Solution Approach 1:
Multiple cooling circuit chambers are nested within the single reservoir tank structure. The first chamber, second chamber, and third chamber are arranged inside the tank body, with partition walls creating nested compartments that efficiently utilize the available installation space while maintaining independent temperature zones.
4Temperature
If separate reservoir tanks are used for different cooling circuits, then temperature management for each circuit is improved, but productivity decreases
Solution Approach 1:
Multiple reservoir tanks are merged into a single integrated assembly, simplifying the installation process. The unified structure with pre-defined chambers and partition walls reduces assembly complexity and installation time, thereby improving productivity while maintaining the ability to manage different temperatures for different cooling circuits.
