Solution Overview
Problem
Existing thermal management systems face challenges in arranging fluid elements and channels to minimize resistance to fluid flow between them.
Innovation Solution
A fluid assembly and control device are designed with a housing assembly, valve assembly, and pump assembly, featuring a first valve cavity, accommodating cavity, and fluid channel, with the impeller assembly and valve core positioned at different heights to reduce fluid resistance, and integrated structures to simplify the fluid channel configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the impeller assembly and valve core are arranged coaxially or at the same height, then the structure is simpler, but the fluid channel complexity increases and fluid flow resistance increases
Solution Approach 1:
The patent applies dimensional change by arranging the impeller assembly and valve core at different heights in the vertical direction, rather than keeping them coaxial or at the same height. This spatial reconfiguration in the height dimension allows for optimized fluid flow paths that reduce resistance while maintaining structural integrity. The fluid channel connects these components at different elevations, creating a more efficient flow trajectory.
2Ease of operation
If the fluid channel is made complex to connect the impeller assembly and valve core, then the components can be connected, but the fluid flow resistance increases
Solution Approach 1:
The patent optimizes fluid flow parameters by changing the spatial arrangement of components (impeller assembly and valve core at different heights) and designing the fluid channel with specific geometric parameters that minimize resistance. The channel dimensions, curvature, and connection angles are optimized to facilitate smooth fluid circulation between the pump and valve assemblies.
