Abstract
A redundant cooling device, for an electrical submarine drive motor, includes a first cooling circuit and a second cooling circuit, by which thermal energy may be removed from the electric submarine drive motor. A high degree of operational security and redundancy may be provided, whereby the coolant in the first cooling circuit and the second cooling circuit flow counter-currently through a stator cooling circuit in the region of the electrical submarine drive motor.
Claims25
A redundant cooling device for an electric submarine drive motor, comprising:
- first cooling circuit and a second cooling circuit, adapted to transport thermal energy away from the electric submarine drive motor, wherein coolant of the first cooling circuit coolant of the second cooling circuit are adapted to flow in counter-current through a stator cooling ring of the electric submarine drive motor, in a region of the electric submarine drive motor.
