Axial fan with a moderate noise level for UV LED handheld device

Task:

The power loss of the high-performance UV LED must be effectively dissipated from the thermally contacted heat sink whereby reliability, high efficiency and a moderate noise level play the key role.

Solution:

The axial fan by SEPA EUROPE with ball bearings and dimensions 40x40x20mm. It blows air onto the pin-fin heat sink with 15m³/h and thus keeps the chip temperature at the permitted level.
This functions without problem even at higher ambient temperatures. The service life L10 at 40°C for the fan in question is 70000h and is equivalent to the service life of the LED. The axial fan also has an extremely low power input of a mere 1.2 W.
