Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat dissipation plates are used for heat exchange, then the device structure is simple, but the heat dissipation performance is poor
Solution Approach 1:
The patent employs a nested tube structure where an inner tube is placed inside an outer tube, both concentrically arranged. This nested configuration increases the heat exchange surface area and improves heat dissipation performance while maintaining a compact and simple overall device structure. The inner tube handles primary heat conduction while the outer tube provides secondary heat dissipation, creating an efficient multi-stage heat management system.
2Reliability
If heat dissipation performance is improved, then chip operation reliability is enhanced, but device complexity increases
Solution Approach 1:
The heat dissipation function is segmented into two distinct stages: primary heat conduction through the inner tube and secondary heat dissipation through the outer tube. This segmentation allows each component to be optimized independently while working together to improve overall heat dissipation performance, thereby enhancing chip operation reliability without excessive complexity.
Solution Approach 2:
The nested tube arrangement consolidates multiple heat dissipation functions into a single compact structure, improving reliability through enhanced heat exchange capability while avoiding the complexity of multiple separate heat dissipation components. The concentric design maximizes space utilization and maintains structural simplicity.

AI summary
A concentric tube heat carry-away device includes an outer tube, a tube end fixing cap, and an inner tube. Heat dissipation grooves are arranged inside the outer tube, and the heat dissipation grooves form heat-dissipating channels. The inner tube and the outer tube are arranged to space from each other and form a cooling space. The heat-dissipating channels are arranged in the cooling space. The inner tube is in communication with the cooling space. In the concentric tube heat carry-away device, heat enters through the inner tube and heat is transmitted to the inner tube. An inner tube lead-in end of the inner tube is of a horn shape to accelerate entry of the heat. Afterwards, the heat flows from the inner tube back into the outer tube, and heat is further transmitted to the outer tube. The heat dissipation grooves inside the outer tube accelerates dissipation of heat.
