Abstract (en)

A cooling device (1) designed specially for application to refrigeration units, comprising a chamber (10) which at least partially envelops the casing of an electrically-powered compressor (3) and which contains a fluid with a low boiling point. The chamber (10) is connected to a condenser (12) by a first pipe (13) via which the heated steam ascends and by second pipe (14) via which the steam, after being liquified by the condenser (12), returns to the chamber (10) so that the low boiling point fluid can remove the heat from the compressor (3). <IMAGE>
