REDUNDANT COOLING SYSTEM WITH TWO COOLING CIRCUITS FOR AN ELECTRIC MOTOR

摘要

A redundant cooling device, for an electrical submarine drive motor (1), comprises a first cooling circuit (2) and a second cooling circuit (3), by means of which thermal energy may be removed from the electric submarine drive motor (1). According to the invention, a high degree of operational security and redundancy may be provided, whereby the coolant in the first cooling circuit (2) and the second cooling circuit (3) flow counter-currently through a stator cooling circuit (4) in the region of the electrical submarine drive motor (1).
