Performance and reliability:

DC Cooling Centrifugal Fan is constructed with a thermoset plastic frame and impeller to UL 94-0 standards. This ensures robustness and reliability even in demanding environments. It offers superior insulation resistance of 10MΩ or more with a DC250V megger, while the dielectric withstand voltage is AC500V for 1 second. These features ensure safe and reliable operation in various power supply applications.

Efficient cooling and noise control:

Operating within an ambient temperature range of -10℃ to +70℃, the DC Cooling Centrifugal Fan excels at maintaining optimal temperatures. By effectively removing heat, it prevents overheating and extends the life of temperature-sensitive components. With the lowest possible noise levels, this fan operates quietly, ensuring a peaceful environment for power supply applications.

Combination of natural and forced air cooling:

To maximise heat dissipation, a combination of natural and forced air cooling is recommended for switch mode power supplies. Natural cooling utilises vertical heat sink placement and optional air vents on the PCB for improved air circulation. Forced air cooling, facilitated by the DC Cooling Centrifugal Fan from China factory, uses the airflow generated by the fan to remove heat. Proper alignment of the fan’s blade orientation with the airflow direction optimises ventilation. By adopting this cooling method, the fan effectively manages heat dissipation, enabling stable temperature conditions and extending the overall life of power supply components.

Benefits of integrated cooling:

The integration of natural and forced air cooling enables faster heat dissipation and adapts to fluctuations in ambient temperature and load conditions. This approach optimises cooling performance while minimising the required heat sink area, ensuring stable operation of power supply components regardless of external conditions. In particular, the combined cooling approach reduces the thermal lag associated with fan cooling alone and increases the overall reliability of the rectifier. It is particularly beneficial in unstable temperature environments, offering superior cooling performance and ease of maintenance.
