Radiator Distribution Tubes for Uniform Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat transfer fluid radiators exhibit non-uniform heat distribution, leading to thermal gradients that can be uncomfortable and require higher electrical power consumption to achieve desired temperatures, with the risk of surface temperature exceeding safe limits.
Innovation Solution
Incorporating additional distribution tubes that are fluidly connected to both the lower pipe and blades, allowing the heat transfer fluid to flow through these tubes before entering the blades, thereby improving fluid circulation and heat exchange, and increasing the surface area for convection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat transfer fluid flows directly from the first pipe into the blades through small orifices, then the structure is simple, but the fluid circulation is limited and temperature uniformity is poor
Solution Approach 1:
The patent divides the fluid distribution system into multiple segments by introducing distribution tubes that connect to multiple blades individually. Each blade receives fluid through its own connection, segmenting the flow path to ensure more uniform distribution across all blades and improving temperature uniformity.
Solution Approach 2:
The distribution tubes act as intermediary elements between the first pipe and the blades. Instead of direct connection through small orifices, the distribution tubes serve as intermediate conduits that facilitate better fluid circulation and distribution to multiple blades, resolving the contradiction between simple structure and uniform temperature distribution.
2Temperature
If additional distribution tubes are added to improve fluid circulation and temperature uniformity, then temperature uniformity improves, but device complexity increases
Solution Approach 1:
The distribution tubes serve multiple functions: they distribute fluid to multiple blades, provide additional heat exchange surface area, and improve overall fluid circulation. This multi-functionality justifies the added complexity by delivering multiple benefits simultaneously.
Solution Approach 2:
The patent extends the fluid distribution system into a new dimensional space by adding distribution tubes that run parallel to the blade arrangement. This dimensional extension allows fluid to reach multiple blades more effectively, improving temperature uniformity without requiring excessive complexity in the original plane.
3Object-affected harmful factors
If the radiator surface area is increased to prevent burns, then safety is improved, but the radiator dimensions increase
Solution Approach 1:
The distribution tubes enable different regions of the radiator to have different thermal characteristics. By improving fluid circulation to specific blades, the system can maintain lower surface temperatures in user-contact areas while preserving heating efficiency, thus reducing burn risk without increasing overall dimensions.

Implementation Method 1
the fluid loses heat to the surrounding environment... enabling convection heat exchange
Implementation Method 2
