The Thermal Management Challenge in Low-Altitude Flight – A Breakthrough Solution

The rapid adoption of low-altitude aircraft in logistics, inspection, and passenger transport is placing unprecedented demands on core component performance. The highly integrated electronic systems within these aircraft, particularly the power batteries and motor controllers, generate significant heat during high-efficiency operation. Traditional thermal management solutions are struggling to meet the cooling requirements of such high power density and extreme operating conditions. Cooling efficiency directly impacts flight safety, endurance, and equipment longevity, becoming a critical bottleneck for industry-wide technological advancement. In this context, leveraging its profound expertise in aerodynamics and high-voltage electrical systems, Sunxfan introduces the revolutionary 810Vdc high-voltage axial fan—a breakthrough technology injecting powerful "cooling momentum" into the low-altitude flight industry.

I. Core Technology: Three Features Defining a New Industry Standard

The Sunxfan 810Vdc high-voltage axial fan is not a simple iteration of traditional products but a comprehensive technological redesign tailored for the unique demands of low-altitude flight applications.

1. Exceptional Adaptability via Wide Voltage RangeThe fan supports a wide operating voltage range of 460V to 810V DC. This design enables seamless compatibility with various low-altitude aircraft electrical platforms. Whether for current mainstream 600V-level architectures or future systems evolving towards 800V, the fan ensures stable operation. Its wide voltage compatibility significantly reduces system integration challenges and parts management costs for OEMs, offering greater flexibility in electrical design for platform upgrades and iterations.

2. Dual High-Voltage Isolated Inputs & Intelligent Communication for Safety and ControlThe fan incorporates a dual high-voltage isolated input design. This redundant power supply substantially enhances system reliability; even if one input fails, the fan can continue operating, providing a dual layer of protection for flight safety. The integration of CAN FD (Controller Area Network Flexible Data-Rate) communication is central to its intelligent capabilities. It enables high-speed, reliable data exchange with the aircraft's main control system, transmitting real-time operational status—such as speed, temperature, and fault codes—and receiving precise speed control commands. This facilitates dynamic cooling strategies based on real-time flight conditions, achieving true "on-demand cooling" and optimizing overall energy consumption.

3. Proven Application: Successful Deployment in the Xpeng A868The true value of technology lies in its practical application. The Sunxfan 810Vdc high-voltage axial fan has been successfully implemented for the first time in Xpeng Huitian's "A868" low-altitude aircraft. During rigorous testing and actual flight verification of the A868, this fan demonstrated outstanding cooling performance, environmental adaptability, and operational reliability, effectively ensuring the stable operation of the aircraft's core motor control systems under prolonged, high-load conditions. This benchmark case not only validates the product's technological maturity but also provides a trustworthy cooling solution template for the entire low-altitude flight industry.

II. Industry Impact: Infusing High Reliability into the Low-Altitude Economy

The launch of the Sunxfan 810Vdc high-voltage axial fan holds significance that extends far beyond the product itself.

Enhances Overall Performance and Safety Margin: Efficient active cooling directly translates into more sustained peak performance output for the aircraft and a lower risk of overheating, laying a solid foundation for extended equipment life and enhanced flight safety.

Accelerates High-Voltage Platform Adoption: This product removes a key obstacle in the thermal management环节 of high-voltage electrical architectures, strongly propelling the low-altitude flight industry towards higher voltage, more efficient electrical systems.

Sets a New Benchmark for Core Components: By integrating high-voltage compatibility, redundant safety, and intelligent communication, Sunxfan is redefining the technical standard for aircraft cooling components, driving the supply chain towards higher reliability, integration, and intelligence.
