Flexible Display Cooling With an Oscillating Heat Pipe

The heat pipe is designed to be flexible rather than rigid, allowing it to dynamically adapt its configuration as the flexible display moves between folded and unfolded states. This dynamic flexibility ensures continuous thermal coupling between the heat source and heat pipe across different device configurations, resolving the thermal management inefficiency while preserving adaptability.

The heat pipe's physical state parameters (flexibility, thermal conductivity) are optimized to change appropriately with the display configuration. By using a flexible heat pipe material with maintained thermal conductivity, the system adapts thermal transfer parameters to match the varying heat dissipation requirements in different configurations, improving both adaptability and thermal management.

The traditional rigid heat pipe is replaced with a flexible heat pipe that uses flexible shell structures and thin film materials. This allows the heat pipe to bend and flex with the display while maintaining its heat transfer function, simultaneously achieving both thermal efficiency and flexibility for adaptive form factors.

The heat pipe employs composite materials that combine flexibility with thermal conductivity. By using composite structures (such as flexible metals or metal-polymer composites), the system achieves the dual property of being both flexible enough to move with the display and thermally conductive enough to manage heat effectively.

Different regions of the flexible display structure have different mechanical properties. The areas requiring flexibility (for movement) are made highly flexible, while the areas requiring heat rejection are provided with enhanced rigidity through the heat pipe structure and condenser regions. This local differentiation allows the system to have both movement capability and structural rigidity where needed.

The flexible display is segmented into functionally distinct regions: flexible areas for movement and rigid areas (with heat pipe and condenser) for heat rejection. This segmentation allows each region to optimize its mechanical properties for its specific function, achieving both adaptability and structural rigidity without compromise.
