Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat exchange fins are placed between the coils to improve cooling performance, then heat exchange efficiency is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the heat exchange function into the support structure itself by making the support curved to form conduits that expose multiple faces to ambient air. This integration eliminates the need for separate heat exchange fins, achieving effective heat dissipation while maintaining structural simplicity and reducing manufacturing complexity.
2Temperature
If fans are used to establish forced air convection for cooling, then heat dissipation efficiency is improved, but energy consumption increases and reliability decreases
Solution Approach 1:
The patent employs natural convection where ambient air flows freely through the conduits formed by the curved support structure without requiring external fans or forced circulation systems. This self-service approach eliminates moving parts that could fail, reducing energy consumption while improving reliability and maintaining effective heat dissipation from the heat source.
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 solution provides efficient and reliable cooling with increased performance and reduced complexity, using natural convection to dissipate heat across multiple faces, thus improving cooling efficiency and reducing energy consumption.
Implementation Method 1
an oscillating heat pipe (252) in which a phase-change heat transfer fluid (251) circulates
Implementation Method 2
The oscillating heat pipe comprises a hot section located below the conduction element 13 and cold sections located in lateral zones of the coil
Implementation Method 3
This difference allows the heat carried by the heat transfer fluid to diffuse within the two plates to the two large opposite faces of the support
Implementation Method 4
The cold sections then dissipate the heat to the environment by convection with the ambient air

AI summary
The invention relates to a cooling device (200, 400) comprising a support (210, 410) consisting of a first plate (230, 430) joined to a second plate (240, 440), the first plate (230, 430) having on a first large face (231, 431) at least one groove (232, 432) extending between a first lateral edge (233, 433) and a second opposing lateral edge (234, 434) and forming a serpentine shape, the groove (232, 432) being covered by the second plate (240, 440) so as to form an oscillating heat pipe (252, 452), the support (210, 410) being curved so as to form at least one conduit (213, 413) extending from the first lateral edge (233, 433) up to the second lateral edge (234, 434), at least one conduit is partially closed by a thermal conduction plate (220, 420) in contact with the first lateral edge (233, 433) so as to allow a natural flow of ambient air into the conduit(s) (213, 413) formed by the support (210, 410).
