Abstract
The invention concerns a hermetic cooling compressor with an electric motor having a variable speed controlled by a converter cooled by a cooling medium flow. The compressor and the converter are formed together as a unit, in which a medium flowing through the unit is used for cooling of the electronic circuit of the converter. Thus the electronic circuit can be made without bulky cooling plates.
