Patent ID: 6904128

Claim:
Device ( 4 ) for cooling a surface ( 30 ) that rotates about an axis ( 1 ) and that faces the axis ( 1 ), which comprises a container ( 40 ) for a liquid coolant ( 41 ) that is disposed between the rotation axis ( 1 ) and the surface ( 30 ) for a co-rotation with the surface ( 30 ), and at least one atomizer nozzle ( 42 ) of the container ( 40 ) which faces the surface ( 30 ) and from which the coolant ( 41 ) is discharged during rotation of the container ( 40 ) due to the centrifugal force (F) acting upon the coolant ( 41 ) in the container ( 40 ) in the form of an atomized jet ( 43 ) that strikes the surface ( 30 ).
