1. Brushless fan classification

Axial flow fan: large air volume, compact structure, suitable for engine compartment cooling.

Centrifugal fan: high air pressure, suitable for forced cooling of air conditioning systems or battery packs.

2. Introduction to brushless fan applications

a. Air conditioning for new energy buses - improve the comfort of drivers and passengers

b. Defroster for new energy buses- improve the safty and comfort of drive

c. Battery thermal management unit - prevent thermal runaway

d. Heat dissipation of hydrogen fuel cell stack - prevent thermal runaway

e. Motor cooling system, etc. - ensure stable operation in high temperature environment

3. Features of brushless fans

Control mode: support PWM and analog voltage speed regulation, with fault feedback function

Protection function: with stall, current limiting, phase loss, soft start, undervoltage and overvoltage protection

Waterproof grade: IP68

Design service life: 40000h

Voltage range: 9V-32V

Operating temperature: -40~120℃

4. Advantages of brushless fans

High reliability, service life of more than 40,000 hours.

Wide temperature adaptability, support -40℃~120℃ working range, can still operate stably at low temperature.

High efficiency and energy saving, the fan supports PWM intelligent speed regulation to reduce power consumption.

Low noise, avoid affecting the comfort of the driver.

Lightweight design reduces vehicle weight and improves energy efficiency.

5. Development Trends

Intelligence: integrated temperature/speed sensor, supports CAN bus communication, and realizes intelligent temperature control.

Integration: integrated design with heat dissipation module to reduce space occupation.

Application of new materials: carbon fiber impellers and ceramic bearings improve life and efficiency.

The application of brushless fans in the field of commercial vehicles is accelerating with the trend of electrification and intelligence. In the future, more attention will be paid to high energy efficiency, long life, and intelligent control to meet stringent commercial needs.
