It is well known that fans are often required to cool power electronics. But how do we determine what a correct fan is and how do we ensure that it provides sufficient cooling? The shape of a fan is an important choice option. It has quite an impact on the size and appearance of a device. Every application has its own possibilities and limitations.
For many applications an ordinary axial fan is sufficient, for others a blower or centrifugal fan is the best choice. In addition, a fan is not always used for cooling, but also to remove, for example, toxic gases or bad smells.
