3D printed fan sleeves – customized size and shape

Fan sleeves are an underestimated accessory as far as electronics cooling is concerned. When applied correctly however, they can avoid the transmission of vibrations and oscillations and significantly reduce the noise development. If you only require small quantities in special dimensions then production using innovative 3D printing would lend itself to this purpose.

Thermoplastic material (TPE) deforms when subject to heat and can be printed in any form. This is cost-efficient and quick. Tool costs that are normally incurred in the case of special productions can be saved. It is best to plan the fan sleeve already during the construction of the housings and devices, however fan sleeves are also suitable for subsequent installation and retrofitting existing devices as they are simple to mount.

The fan sleeves not only create a seal between the intake and pressure chamber, but they also eliminate the transmission of vibrations and oscillations of the fan to the housing wall. The reduction in noise by several decibels is clearly audible. The sleeves also protect the fan against vibrations and this in turn has a positive effect on its service life.
