Inspiriert von der Eule:
MAHLE has developed a bionic high-performance fan that makes commercial vehicles significantly quieter. It was developed for particularly demanding fuel cell and battery electric vehicles. In the AI-supported optimization of the ventilation blades, MAHLE engineers were inspired by the feathers of an owl, one of the quietest birds. The owl’s feathers are said to have a noise-reducing effect. The bionic fan blades can reduce the fan noise of a truck by up to 4 dB(A) – that is more than a halving of the sound power. This significant reduction solves another challenge of e-mobility: loud fan noise, which can be disturbing under full load and also when charging the vehicle at night in residential areas or at service stations. In addition, the fan is significantly more efficient than conventional designs – thanks to a 10 percent improvement in efficiency and a 10 percent reduction in weight. MAHLE also enables the use of its new bionic fan in passenger cars.
