AI Technical Summary
The passive heat dissipation efficiency of existing aluminum alloy heat sinks is limited, leading to overheating and frequency reduction in electronic devices, thus affecting performance.
Built-in micro cooling fan slots are set on the aluminum alloy heat dissipation base plate and fins, and active cooling is achieved by using fans through a connected heat dissipation air duct design. Combined with the air vent structure of the base plate and fins, efficient airflow and heat dissipation are achieved.
It improves heat dissipation efficiency, prevents electronic components from overheating, and ensures the normal operation of electronic equipment.
