Electric motor pod drive system for a vessel with a cooling device

An electric propulsion pod system for a ship, comprising:

• an electric propulsion pod containing an electric motor having an electric motor external region and being fitted within said electric propulsion pod for providing a water propulsion wherein said electric motor generates an amount of electric motor heat, said electric propulsion pod including an electric propulsion pod outer wall defining an electric propulsion pod surface;
• a ship access shaft being secured below said ship and immersible in water for connecting said electric propulsion pod to said ship, said ship access shaft including a ship access shaft outer wall defining a ship access shaft surface, a ship access shaft hollow region and a ship access shaft lower end;
• said electric propulsion pod being connected to said ship access shaft at said ship access shaft lower end wherein an electric propulsion pod transition region is defined;
• said electric motor heat being conducted by said electric propulsion pod surface in an amount greater than by said ship access shaft surface of said electric propulsion pod transition region wherein said amount of electric motor heat is subsequently released from said electric propulsion pod surface and from said ship access shaft surface into said water;
• an electric propulsion pod heat rejection member being fitted for increasing said amount of electric motor heat being conducted and released into said water;
• and
• wherein said electric propulsion pod heat rejection member comprises said ship access shaft lower end having a ship access shaft double-walled configuration, said ship access shaft double-walled configuration has an inside ship access shaft double-walled region that contains a heat conducting media, said heat conducting media consists of air and water.
