Working Principle
The Semicera cooling module operates based on piezoelectric actuation and airflow modulation:
- Electrical excitation drives the piezoelectric ceramic layers
- The structure generates ultrasonic vibration
- Internal air is periodically compressed and accelerated
- High-speed airflow is directed toward the heat source
- Heat is removed through forced convection
This mechanism enhances heat transfer by disrupting the thermal boundary layer, significantly improving cooling efficiency compared to passive solutions.
