Air-gap cooling device for magnetic bearing for magnetic levitation high-speed train with projecting ribs on one side of air-gap for passive deflection of cooling air flow

摘要

The air-gap cooling device has at least one of the opposing walls (9,17) defining the air-gap (3) provided with projecting ribs for sidewards deflection of the cooling air flow, extending parallel to one another at an angle to the relative movement direction between the travel track (1) and the sub-frame (2) of a high-speed train.
