DC Cooling Fan for Frequency Converter and Drive Systems
SZR inverter cooling fans are developed for power conversion equipment requiring efficient airflow management, low motor interference and stable long-duration cooling performance. The fan series improves internal heat dissipation efficiency while supporting reliable operation under fluctuating electrical loads. These products are commonly installed in variable frequency drives, solar inverters, UPS systems and industrial motor controllers.
Product Configuration
The external housing adopts reinforced aluminum alloy construction with protective surface coating for improved corrosion resistance and mechanical durability.
Fan blades are manufactured from high-temperature resistant thermoplastic material to maintain structural balance under continuous operation.
The brushless DC motor incorporates electromagnetic optimization technology to reduce interference with inverter circuitry.
Optimized blade curvature improves airflow concentration and heat transfer efficiency inside compact electrical enclosures.
