Abstract
The present invention relates to an induction heating coil comprising a litz cable which is wound into a spiral to form a bobbin, and means for cooling said cable indirectly. The litz cable is arranged to be cooled by means of an indirect cooling system that comprises a tube which is wound in an intermeshed fashion with the windings of the litz cable. The present invention relates also to a method on a paper or board machine or on a paper finishing machine, in which method at least one induction heating coil comprising a wound litz cable is used for heating a component, and said coil is cooled indirectly by a cooling medium.
