With the advancement of technology, the technology and performance of cooling fans are also constantly developing and improving. At present, the specifications and dimensions of heat dissipation fans range from a few millimeters to several hundred millimeters, and there are various voltage options, such as 5V, 12V, 24V, etc. In addition, there are also various shapes of heat dissipation fans, such as square, circular, olive shaped, etc.
In modern home life, technological progress has not only changed our way of life, but also improved our quality of life. The emergence of smart toilets is undoubtedly a major innovation in the bathroom field. They are equipped with heating seats, warm air drying, automatic flushing and other functions, making users feel extremely comfortable during use while effectively reducing the risk of infection caused by unclean bathroom facilities.
In the fast-paced modern life, the emergence of dishwashers has brought about earth shattering changes in our home life. Washing dishes is a tedious and time-consuming task that requires us to personally clean every dish, dry it, and store it in the sun.
The emergence of drones has provided us with new ways and perspectives to understand things. In the past decade, their applications have become increasingly popular. The express delivery industry, film and television shooting, monitoring and inspection, transportation, agriculture, forestry, police security, surveying and mapping, and other fields have shown a significant increase in demand for drones.

In fields such as industrial automation, medical equipment, and new energy, the stability of high-voltage power supplies is directly related to the operational safety and lifespan of equipment. However, if the extreme heat generated by high-voltage environments is not dissipated promptly, it can lead to reduced efficiency at best, or even component breakdown or explosion at worst. To address this industry challenge, the Xingdong DC axial-flow fan 5010, with its three core advantages of high reliability, strong heat dissipation, and strict insulation protection, has become a "safeguard" for high-voltage power supply heat dissipation. This article will provide a technical analysis and fully explain how this DC axial-flow fan safeguards high-voltage power supplies.
1. Special Challenges of High-Voltage Power Supply Cooling
High-voltage power supply operating environments are far more demanding than those of ordinary equipment: high temperature and high voltage coexist: When outputting high power, the temperature of power devices (such as IGBTs and MOSFETs) can reach over 150°C.
Electrical safety risks: Poor insulation in traditional fans can cause leakage or arcing.
Complex operating conditions: Outdoor equipment must withstand harsh environments such as high temperature, humidity, and dust.
Low noise requirements: Medical and laboratory environments are extremely sensitive to noise control. The Xingdong DC Axial Fan 5010 perfectly addresses these challenges through special insulation treatment, wide voltage compatibility, and a dust- and water-resistant design.
II. Core Advantages of the Xingdong DC Axial Fan 5010
Designed for high-voltage scenarios: "Safety Gene"
Reinforced insulation protection: Utilizing insulating materials that have passed voltage testing (withstands 5000V AC/1 minute), eliminating the risk of electrical leakage.
No metal blades: The all-plastic fan blade design prevents sparks and is suitable for flammable and explosive environments.
IP68 protection rating: The dust screen and sealed structure prevent dust and moisture from entering the fan.
Efficient heat dissipation, stable output
Air volume: 7.30-10.43 CFM, precisely covering the heat-generating areas of the high-voltage power module.
Air pressure: 1.77-2.52 mmH₂O, easily penetrating gaps between densely packed components, creating forced convection.
Speed range: 3500-5000 RPM, with PWM speed regulation support, ensuring both efficient heat dissipation and quiet operation.
Military-grade durability. Upgraded materials: PC + fiberglass composite frame, UV-resistant and age-resistant, for long-term deformation. Bearing options: Choose between oil-retaining bearings (cost-effective) or dual-ball bearings (lifespan up to 80,000 hours). Wide operating temperature range: -10°C to +70°C, stable operation, adaptable to extreme environments.
