Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional siphon radiator heat dissipation structure is used, then the device is simple and easy to manufacture, but the heat exchange efficiency is low and cannot meet high-power-consumption requirements
Solution Approach 1:
The fin assembly is segmented into multiple first fins and second fins with teeth structures, creating divided fluid channels that increase heat exchange efficiency. Each fin includes multiple teeth that segment the fluid flow path, allowing better heat transfer between the working medium and the fin surfaces.
Solution Approach 2:
The patent introduces a staggered arrangement of teeth on adjacent fins, creating three-dimensional staggered fluid channels. This dimensional arrangement increases the heat-exchange surface area and improves heat transfer efficiency by utilizing spatial optimization rather than simple linear fin spacing.
2Area of stationary object
If fins are arranged in a stacked manner with staggered teeth, then the heat-exchange surface area is increased, but the manufacturing complexity increases
Solution Approach 1:
The fin structure is divided into modular first fins and second fins, each with standardized tooth configurations. This segmentation allows for standardized manufacturing processes while achieving complex staggered arrangements that maximize heat-exchange surface area.
Solution Approach 2:
The patent optimizes parameters such as tooth width, gap width, and staggering distance to achieve maximum heat exchange efficiency. By carefully controlling these parameters (e.g., first gap width between 0.5-2mm, second gap width between 0.5-2mm), the design balances manufacturing feasibility with performance requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The staggered arrangement of teeth in the fin assembly increases the heat-exchange surface area, improves the ability to absorb waste heat, and enables phase-change heat exchange in high-power-consumption environments, effectively addressing the low heat exchange efficiency of conventional radiators.
Implementation Method 1
the first teeth and the second teeth are arranged in a staggered manner, so that staggered fluid channels are formed between the at least one first fin and the at least one second fin
Implementation Method 2
When power of a heat source is increased, the working medium boils to generate bubbles, and the bubbles then contact a surface of the fin to perform phase-change heat exchange
Implementation Method 3
the bottom plate comprises a first side and a second side, the first side is configured to contact a heat source, and the fin assembly is mounted on the second side
