Movable Vane Heat Dissipating Module for Dynamic Airflow Control

The patent implements a movable vane that can dynamically adjust its position to control airflow through the heat sink. The vane is connected to a driving unit that can change its angle or position based on temperature detection, allowing the system to optimize heat dissipation without requiring multiple fixed components. This dynamic adjustment enables a single heat sink to perform the work that would otherwise require multiple static heat sinks and fans.

The movable vane serves multiple functions: it controls airflow direction, regulates the amount of air passing through the heat sink, and can be positioned to optimize cooling for different operating conditions. This single multi-functional component replaces what would traditionally require multiple separate fans and heat sinks, reducing both component count and manufacturing cost while maintaining effective heat dissipation.

The patent extracts the heat dissipation function from the housing structure itself. Instead of forming holes directly in the housing, the invention uses a separate ventilation device with a movable vane that can be positioned to allow heat dissipation when needed while maintaining the integrity and appearance of the housing when the vane is in its closed position. This separates the aesthetic housing from the functional ventilation system.

The system changes the parameter of airflow control by using a movable vane to adjust the cross-sectional area through which air flows. Instead of increasing fan speed to increase airflow, the invention changes the flow path geometry by moving the vane to different positions, thereby controlling the amount of air that passes through the heat sink at a given fan speed. This parameter change allows effective heat dissipation at lower, quieter fan speeds.
