Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiators face challenges with fluid inlet and outlet placement, leading to design complexities, leakage risks, and inefficient fluid flow due to external connections and U-shaped circuits that increase pressure drop and heat-related deterioration.
Innovation Solution
A radiator design featuring a tube connecting the inner spaces of two tanks with strategically located ports and internal partitions within the tube to compartmentalize fluid flow, enhancing mechanical resistance and reducing pressure drop while optimizing space and fluid flow efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If inlet and outlet ports are located on opposite sides of the radiator, then fluid flow path is simplified, but it becomes significantly difficult to locate ports in opposite areas due to engine design or size constraints
Solution Approach 1:
The patent introduces a vertical dimension to the port arrangement by positioning inlet and outlet ports at different heights on the same side of the radiator. This dimensional change allows the fluid circuit to achieve simplified flow path characteristics without requiring horizontal separation across opposite sides, thereby resolving the conflict between circuit simplicity and adaptability to engine constraints.
2Adaptability or versatility
If external connections or sleeves are used to connect inlet and outlet, then port location flexibility is improved, but leakage risk increases and sleeves are susceptible to heat deterioration
Solution Approach 1:
The patent merges the inlet and outlet ports directly into the radiator tank structure itself, eliminating the need for separate external sleeves or connections. This integration ensures that ports are permanently and reliably sealed within the tank, reducing leakage risk while maintaining the flexibility to position ports appropriately on the same side of the radiator.
3Volume of moving object
If U-shaped circuits are used with inlet and outlet ports in the same tank, then space is optimized, but pressure drop increases fourfold due to liquid passing through ducts twice
Solution Approach 1:
The patent segments the fluid flow path into distinct inlet and outlet regions within the same tank by strategically positioning ports at different locations. This segmentation allows the fluid to enter through one port and exit through another without requiring a U-shaped path that traverses the entire duct length twice, thereby reducing pressure drop while maintaining compact space utilization.
