Efficient Axial Ventilation Fan for Electronic Thermal Management
SZR's Brushless DC cooling fan series is engineered for reliable heat dissipation in industrial electronics, communication equipment and intelligent control systems. The axial airflow design delivers consistent ventilation performance with efficient power consumption.
Cooling Operation
The brushless motor system eliminates mechanical brush friction, improving operational stability and extending service life compared with conventional motor structures.
The axial airflow pathway supports rapid heat exchange across electronic components and internal equipment structures. Optimized blade geometry enhances airflow distribution while maintaining balanced operating efficiency.
Available in multiple DC voltage platforms including 5V, 12V and 24V configurations.
Mechanical Design
The fan housing adopts UL94V-0 flame-retardant thermoplastic material to improve durability and operational safety.
The dynamically balanced impeller minimizes vibration during continuous rotation, while precision copper coil winding contributes to efficient motor performance. Multiple bearing options are available to satisfy different environmental and lifespan requirements.
PWM intelligent speed control and tachometer output can be integrated for system monitoring applications.
