AI Technical Summary
Technical Problem
In existing cooling fans, the heat from the drive motor and PCB is difficult to dissipate effectively, causing the motor and circuit board temperatures to rise, which affects the stability and lifespan of the equipment.
Method used
A cooling fan impeller structure is designed, including a first impeller hub, a second impeller hub, cooling blades, and fan blades. The cooling blades are located between the two impeller hubs and dissipate heat from the drive motor and circuit board through the airflow channel, thereby improving the heat dissipation efficiency.
Benefits of technology
The efficient use of the fan's own drive motor and circuit board improves the fan's reliability and stability, reduces noise, and extends the equipment's lifespan.
