12 Volt DC Axial Fans

3828 Micro Fan

With this function,the speed can be controlled by applying a pulse width modulated signal whose frequency maybe in the range of 25k Hz~30kHz.High voltage means 3~10V.Low voltage means 0~0.8V.Normally two kinds "Speed Vs duty cycle curve" are used.

 

The global heat dissipation fan market is experiencing steady growth, with the Chinese market alone expected to reach 200 billion yuan in 2025, driven by the continuous upgrading of electronic and industrial equipment . As a key segment of this market, 12V DC axial fans are favored for their energy efficiency and flexibility. The 38x38x28mm model, in particular, embodies the industry's development trend of "miniaturization, high performance, and intelligence" . Don't be fooled by its compact dimensions-this small fan packs a powerful punch. With a maximum speed of 20,000rpm, it delivers an air volume of 23cfm and a wind pressure of 56.6mmH2O. These impressive parameters mean it can quickly and effectively dissipate heat from high-power components, even in confined spaces where traditional large fans cannot fit. Whether it's cooling precision electronic controls or relieving heat buildup in industrial equipment, its outstanding performance is more than sufficient to meet diverse cooling needs.

The exceptional performance of this 12V DC axial fan stems from its sophisticated structural design and high-quality material selection. The frame and blades are crafted from PBT environmentally friendly flame-retardant material, a choice that aligns with the industry's shift toward green and safe components . PBT plastic, as a crystalline thermoplastic, boasts excellent mechanical strength, electrical insulation, and chemical corrosion resistance . It can withstand long-term use at temperatures up to 120℃, ensuring the fan remains structurally stable and does not deform under high-temperature operating conditions. Additionally, PBT's good dimensional stability prevents warping due to thermal expansion and contraction, while its anti-static properties reduce dust accumulation, further enhancing the fan's operational efficiency and lifespan . The fan's moving and static blade design is another highlight-this optimized structure maximizes air volume and wind pressure, creating a more efficient air circulation path that ensures targeted and rapid heat dissipation.

To further boost reliability and longevity, the fan adopts a copper mid-tube design. Copper's superior thermal conductivity helps dissipate heat generated by the motor itself, preventing overheating and ensuring stable operation. This design not only improves the fan's overall stability but also extends its service life, a critical advantage for equipment that requires long-term continuous operation. In industrial settings where equipment downtime can lead to significant production losses, a long-lasting, low-maintenance fan like this becomes an invaluable asset.

Practicality and adaptability are two more areas where this 12V DC axial fan excels. Weighing only 41g, it is extremely lightweight, making installation and transportation a breeze. For on-site maintenance teams or equipment integrators, this means reduced labor costs and more flexible deployment options-whether it's installing the fan in a compact control cabinet or carrying it to a remote construction site for emergency heat dissipation needs. The fan is also equipped with PWM speed regulation and FG signal feedback functions, which reflect the industry's move toward intelligent heat dissipation solutions . PWM speed regulation allows users to adjust the fan's speed according to actual heat dissipation requirements, balancing cooling efficiency and energy consumption. The FG signal feedback function provides real-time speed monitoring, enabling timely detection of abnormalities and ensuring the fan operates within safe parameters. This intelligent control capability makes the fan suitable for precision equipment that requires precise heat management, such as electronic control systems in manufacturing plants.

One of the most notable features of this fan is its IP68 waterproof rating, a top-tier protection level that positions it as a leader in harsh environment applications . The IP68 rating means the fan is completely dust-tight and can withstand long-term immersion in water, making it ideal for use in humid factories, dusty construction sites, salt-laden coastal industrial areas, or rainy outdoor environments. As more industrial equipment moves outdoors or into complex environments, high-protection-grade fans like this are no longer optional but a necessity . Compared to ordinary fans with IP20-IP30 ratings, which are only suitable for clean indoor environments, this IP68 fan offers significantly lower failure rates and longer service life-operating for 50,000 to 100,000 hours or more, compared to 10,000 to 30,000 hours for ordinary fans . This translates to lower replacement and maintenance costs for enterprises in the long run.

The fan's attention to detail is evident in its power cord design. The wires are protected by heat shrink tubing, which effectively resists abrasion, corrosion, and high temperatures, preventing line damage and short circuits. This protection is crucial in harsh industrial environments where wires are prone to being crushed, scratched, or exposed to chemicals. Combined with its wide operating temperature range of -40℃ to +80℃, the fan can adapt to extreme cold and heat-from frigid mining sites in northern regions to high-temperature workshops in southern factories. This broad temperature tolerance ensures the fan remains operational in almost any climate condition, providing consistent heat dissipation support.

The versatility of this 12V DC axial fan is reflected in its wide range of applications across multiple industries. It is a reliable heat dissipation solution for manufacturing plants, where it cools production line equipment and control systems; machine repair shops, where it provides temporary or permanent cooling for repaired machinery; construction projects, where it keeps construction machinery and on-site electrical equipment cool; and energy and mining sites, where it withstands harsh conditions to ensure the stable operation of drilling and extraction equipment. Beyond these core areas, the fan also has potential applications in emerging fields such as energy storage systems, where it can cool battery packs and BMS controllers, and 5G communication base stations, which require high-protection fans to withstand outdoor elements . As the global market for heat dissipation fans continues to grow-projected to reach approximately 115 billion US dollars by 2025 -this high-performance, multi-purpose fan is well-positioned to capture opportunities across diverse sectors.

In summary, the 38x38x28mm 12V DC axial fan is more than just a heat dissipation component-it is a testament to the integration of advanced materials, intelligent design, and practical innovation. Its small size, high performance, IP68 protection, and intelligent control functions make it an ideal choice for modern industrial heat dissipation needs. Whether you're looking to improve the reliability of your production equipment, reduce maintenance costs, or adapt to harsh operating environments, this fan delivers consistent, efficient performance. In an era where heat dissipation directly impacts equipment performance and business productivity, investing in a high-quality 12V DC axial fan like this is an investment in operational stability and long-term success.

For businesses seeking reliable heat dissipation solutions, this 12V DC axial fan stands out as a trusted partner. Its combination of performance, durability, and versatility makes it suitable for a wide range of applications, while its compliance with environmental and safety standards ensures it meets the rigorous requirements of modern industries.
