Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fin heat exchange structure is used, then device structure is simple, but heat exchange efficiency is low due to gaps between fins preventing full contact with heat exchange medium
Solution Approach 1:
The heat exchange structure is segmented into multiple flow channels (first flow channel, second flow channel, third flow channel, fourth flow channel) with distinct inlet and outlet portions. This segmentation allows the heat exchange medium to flow through multiple separate paths, ensuring full contact with the heat exchange fins and eliminating dead zones where gaps would prevent effective heat transfer.
Solution Approach 2:
The patent introduces a multi-dimensional flow channel arrangement where the heat exchange medium flows not only along the length of the fins but also through vertically stacked flow channels. The first and second flow channels are arranged in different spatial dimensions, allowing the medium to access heat exchange surfaces that would be inaccessible in a single-plane configuration, thereby eliminating gaps and improving contact efficiency.
2Productivity
If gaps between fins are not aligned with medium conveying tube, then fin structure is simple to manufacture, but heat exchange efficiency deviates significantly from ideal condition when medium flow speed is fast
Solution Approach 1:
The flow channel structure is pre-designed with inlet portions and outlet portions that are integrally formed with the heat exchange fins. The inlet portion of each flow channel is positioned to align with the gaps between fins before the heat exchange medium enters, ensuring proper flow distribution is established in advance. This preliminary alignment prevents misalignment issues that would occur at high flow speeds in traditional designs.
Solution Approach 2:
The flow channel walls act as intermediaries that guide and distribute the heat exchange medium uniformly across multiple flow paths. Instead of relying on direct alignment between the conveying tube and fin gaps, the flow channels serve as intermediate structures that ensure the medium is properly distributed to all heat exchange surfaces, eliminating the need for precise direct alignment.
3Productivity
If some fins are ineffective for heat exchange due to gap misalignment, then device structure remains simple, but space utilization is reduced and business development is disadvantaged
Solution Approach 1:
Multiple flow channels (first, second, third, and fourth flow channels) are merged into a single integrated heat exchange assembly. The inlet portions of different flow channels are connected to a common inlet, and outlet portions are connected to a common outlet, allowing the heat exchange medium to sequentially pass through multiple flow channels. This merging ensures that all heat exchange fins across different channels are effectively utilized, maximizing space utilization efficiency.
Solution Approach 2:
The flow channel configuration ensures continuous useful action by arranging the flow paths so that the heat exchange medium sequentially passes through the first, second, third, and fourth flow channels without interruption. Each flow channel is designed to maintain full contact between the medium and heat exchange fins throughout the entire flow path, eliminating dead zones and ensuring that all fins contribute continuously to heat exchange, maximizing space utilization.

AI summary
A multiple flow channel full contact fin heat exchange mechanism includes a heat concentration unit and a heat transfer assembly. The heat concentration unit is arranged at a focusing position of a soler energy reflection heat-concentration device. The heat transfer assembly is arranged on the heat concentration unit. Multiple groups of heat exchange flow channels are formed between the heat transfer assembly and the heat concentration unit. Two adjacent groups of heat exchange flow channels are connected in sequence. All of the heat exchange flow channels are arranged parallel in a linear direction. By having the multiple groups of heat exchange flow channels arranged between the heat transfer assembly and the heat concentration unit and two adjacent groups of heat exchange flow channels connected in sequence and arranged in parallel in a linear direction, fluid flowing in the heat exchange flow channels directly contacts the heat transfer assembly.
