Beschreibung
Zusammenfassung:	The present disclosure relates to a ship's propulsion unit which includes: a closed liquid cooling system having an inner space containing liquid. The inner space is partly limited by a cylindrical outer surface of a cylindrical section of a motor housing section of the propulsion unit for exchanging thermal energy between an electric motor arranged in the cylindrical section of the motor housing section and liquid in the inner space. The inner space of the closed liquid cooling system is partly limited by the shell structure of the propulsion unit so that liquid in the inner space is in direct contact with the shell structure of the propulsion unit for exchanging thermal energy between liquid in the inner space and water surrounding the propulsion unit via the shell structure of the propulsion unit.
