We have developed specialized ventilation and cooling systems for mobile scenarios such as automobiles and ships.Explosion-proof fans for battery compartments of new energy vehicles have a response time of < 50ms,which ensures the temperature balance of battery packs,axial fans for ship cabins can withstand continuous vibration under class 6 sea conditions through anti-seismic design. The innovative micro-channel heat exchanger fan with integrated humidity sensor maintains a defrosting efficiency of over 90% at low temperatures of -30℃, which is used in refrigerated trucks,caravans and other special vehicles to enhance travel comfort and equipment reliability.
