Innovative fan of Mahle: owl design reduces noises considerably

Innovations in traffic: meal contribution to noise reduction

The IAA Transportation 2024 in Hanover impressively shows how technology can contribute to improving urban habitats. Mahle reveals a newly developed bionic high -performance fan, which is intended to significantly reduce the noise emissions of electric vehicles and fuel cell vehicles. This technological innovation is particularly relevant at a time when traffic in urban areas is getting louder and the quality of life of the residents.

Sustainability and efficiency: technological progress

The Bionic fan of Mahle, inspired by nature, specifically from the owl, offers noise reduction of up to 4 dB (a). This corresponds to a significant halving of the sound performance, which is not only desirable, but necessary in noise -sensitive areas such as residential areas or rest areas. Through artificial intelligence (AI), the aerodynamic properties of the owl feather swinging were successfully imitated, which leads to an improved performance of the fan.

Advantages for vehicle manufacturers and users

This new technology is not only quieter, but also more efficient. While the efficiency was increased by 10 percent, the weight of the fan was also reduced by 10 percent. Mahle offers this solution in a wide range of services from 300 watts to 35 kW, which means that the bionic fan can be used in private electric cars and heavy load vehicles. The first tests with prototypes from different vehicle manufacturers are already underway.

Additional innovations at the fair

In addition to the high-performance fan, Mahle will also present an innovative evaporation cooling for fuel cell vehicles on the IAA. This technology enables a 50 kW higher cooling capacity with the same installation space. In addition, a new PowerCell unit (H2-PCU) is presented, which should ensure stable operation of hydrogen engines. Mahles presentation under the motto "variety of technology" illustrates the company's commitment to sustainable mobility.

Insights for trade visitors and publicity

Expert visitors at the IAA Transportation have the opportunity to find out in detail about the latest developments in the field of electrification and thermal management. Mahle not only developed the bionic fan, but also shows how all the products presented are ready for series production and what positive effects these innovations have on traffic technology.
