Abstract
A method for cooling a device such as an electric motor drive or a general power converter, said device comprising a heatsink, electronic components connected to the heatsink, a heat pipe connected to the heatsink, an inlet air temperature measuring device and a cooling fan. According to the method, the drive establishes whether the inlet air temperature is below a first temperature threshold value and operates the cooling fan at a low inlet air temperature speed regime if the inlet air temperature is below the first temperature threshold value. The invention is also directed at a device such as an electric motor drive or a general power converter for performing the cooling method.
