In high-voltage power supply systems, excessively high operating temperatures not only accelerate the aging of internal power devices, causing their electrical parameters to drift, but also significantly reduce system stability and potentially cause serious faults such as short circuits and overcurrent. As a core thermal management component, the heat dissipation performance of the DC axial-flow fan 4010 is directly related to system reliability and service life. This article will focus on the DC axial-flow fan 4010 and explore its important role in ensuring reliable power system operation.

I. Heat Dissipation Challenges of High-Voltage Power Supplies

Due to the high voltage and high current characteristics of the internal circuits, high-voltage power supplies face numerous heat dissipation challenges during operation:

Heat Generation Characteristics: Operation generates significant amounts of heat. Driven by high voltage and high current, circuit components continuously heat up.

Heat Accumulation Hazards: If heat cannot be dissipated promptly, the internal temperature of the power supply will rise rapidly. In high-voltage power supply applications such as industrial equipment and communication base stations, sustained high temperatures can cause capacitor bulging and transistor performance degradation, impacting normal equipment operation.

Limitations of Traditional Heat Dissipation: Traditional heat dissipation methods, such as natural heat dissipation or simple heat sinks, are unable to cope with the high heat generated by high-voltage power supplies and cannot meet the demand for efficient heat dissipation.

2. High-Voltage Cooling Technology Advantages of the DC Axial Fan 4010

Compact Size, Flexible Compatibility

Compact Size: The DC Axial Fan 4010 measures 40×40×10mm, making it lightweight and compact, making it easy to install in space-constrained areas within high-voltage power supplies.

Flexible Installation: It can be precisely deployed in tight spaces, such as between power modules or around heat-generating components, to dissipate heat for critical components without disrupting the overall layout.

Powerful Performance, Efficient Cooling

Core Parameters: Speed ​​Range: 4200-6000 RPM, Air Volume: 4.48-6.40 CFM, Air Pressure: 2.32-3.31 mmH₂O.

Cooling Performance: Powerful airflow quickly dissipates heat from the high-voltage power supply, ensuring stable operation.

Automatic Speed ​​Control, Energy-Saving and Quiet

PWM Speed ​​Control: Supports PWM intelligent speed control, automatically adjusting the speed based on the internal temperature of the power supply. Energy-Saving and Noise-Reducing: Speed ​​and noise levels are reduced at low loads, reaching below 21dBA at night. Under high loads, the fan automatically increases speed to enhance heat dissipation, achieving both energy efficiency and quiet operation.

Durable and Reliable, Long-Term Operation

Material and Craftsmanship: The outer frame is constructed of a PC + fiberglass composite material, which is heat-resistant and age-resistant, resisting deformation in high-temperature environments.

Bearing Advantages: Optional double ball bearings offer low friction, high wear resistance, and a service life of up to 80,000 hours, reducing maintenance costs and the risk of equipment downtime.

The 4010 DC axial-flow fan, with its compact size, high heat dissipation, intelligent energy saving, and durability, provides a perfect solution for high-voltage power supply cooling challenges. Whether used in large-scale industrial equipment or base station facilities in the communications industry, the 4010 fan demonstrates exceptional value and is an ideal choice for high-voltage power supply cooling.
