Fan Applications in Vehicle Ventilation

Fans play an indispensable role in the ventilation systems of all types of vehicles (cars, trucks, trains), ensuring the comfort and safety of passengers and drivers, while also guaranteeing the normal operation of internal vehicle equipment.

In cars, the most common fan applications are within the air conditioning system, responsible for circulating hot or cold air into the cabin, and radiator fans, which cool the engine. Furthermore, the cooling of battery packs in new energy vehicles heavily relies on high-performance fans.

For trucks, beyond the cab's air conditioning and engine cooling, fans are also essential for temperature control in cargo areas (like refrigerated trucks), preserving the quality of goods during transport.

Trains have even more complex ventilation needs. In passenger trains, fans are used for air circulation and air conditioning supply within carriages, as well as for odor removal. Inside the locomotive (train engine), high-power fans are responsible for cooling critical electrical equipment such as traction motors and converters, ensuring the train's stability during high-speed operation.

In these applications, fan selection must consider vibration, noise, space constraints, energy consumption, and the ability to operate in extreme temperatures, to meet the demanding operational environment unique to vehicles.
