Fans and Blowers for Automotive Applications

If you think about it then this makes a lot of sense: fans andblowers can be found in all areas of our life. Engines have a largefan to make sure they dont overheat, there are fans to ventilateyour bathroom, fans are the backbone of every kitchen exhaust hood,and theyre increasingly being used in automotive applications.Besides the fact that fans are used for the ventilation and airconditioning of the passenger cabin, there are many other placeswhere heat needs to be dissipated, e.g. the engine electronics,which nowadays is powered by processors not much less powerful thanour PC hardware. When we asked about more details about automotive applications,Sunon mentioned LED head lights as an example. Despite being verybright and energy-efficient, LEDs do get hot according to Sunon hot enough to require active cooling. We havent seen a massproduction car that would already be equipped with LED head lights,but this isnt more than a few years away now. Another example is the Mercedes SLK roader A Fans Scarf feature,which transports hot air up to an opening to warm your neck in coldwinter days  should you decide to drive open despite cold weather.Sunon also provides fans for the Mercedes S class, where seats aretypically not only heated, but also ventilated. BMW is another ofSunons customers: The Bavarian car makers utilize Sunon fans fortheir engine control boxes (see image).
