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.
