1. EC electronic commutation technology, efficient and energy-saving by 50%<\/h3>\n

This is the core highlight of this fan: it adopts EC brushless DC motor technology, which improves energy efficiency conversion rate by about 50% compared to traditional AC induction motor fans. With the same heat dissipation effect, power consumption is reduced by half, and long-term use can significantly save electricity costs; Simultaneously supporting soft start function, with low starting current and minimal impact on the power grid, protecting the equipment circuit system.<\/p>\n

\u00a02. 100-240V wide voltage input, globally applicable without conversion<\/h3>\n

The wide voltage design is compatible with global power grid standards, whether it is 110V North American standard, 220V Chinese standard, or 240V European standard, no additional voltage converter is required. One fan travels around the world, making it particularly suitable for export equipment matching and cross-border project use.<\/p>\n

3. Complete intelligent control functions and higher temperature control accuracy<\/h3>\n

Supports PWM pulse width modulation (0-100% stepless speed regulation), FG speed signal feedback (real-time monitoring of speed), RD stall alarm (timely reminder of abnormal situations), seamlessly integrates with equipment control systems to achieve precise temperature control, extend equipment service life, and reduce noise and energy consumption.<\/p>\n

\u00a04. Industry standard size with strong interchangeability and compatibility<\/h3>\n

The 60mm series standard universal specification is 60 \u00d7 60 \u00d7 25mm, and the bracket installation hole position (50mm \u00d7 50mm) is fully compatible with AC\/DC fans of the same size. Equipment maintenance and replacement, complete machine matching, and project modification do not require adjusting the rack and openings, and are compatible with all 60mm cavity devices on the market, resulting in lower procurement and usage costs.<\/p>\n

AI Liquid Cooling Application: Large-Format Cooling for High-Power AI Infrastructure<\/h2>\n

The Fengheng 172\u00d751mm fan series \u2014 available in both DC and EC motor versions \u2014 is designed for high-airflow, high-static-pressure applications in AI data center liquid cooling infrastructure<\/strong> where 120mm fans cannot deliver sufficient airflow per unit.<\/p>\n

Why 172mm for AI Liquid Cooling?<\/h3>\n

As rack power densities exceed 100 kW and CDU systems scale to serve 20+ racks, the airflow requirements of individual RDHx doors and CDU cabinets increase beyond what arrays of small fans can efficiently handle. The 172mm format provides:<\/p>\n
