1. In an induction heating device including at least one inductor adapted to heat inductively a workpiece magnetically coupled thereto, a radio-frequency transformer having a secondary winding coupled to said inductor and a primary winding adapted to be coupled to a source of radio frequency energy, said secondary winding and said primary winding being generally cylindrical, having respective central axes, and being telescopically and generally coaxially positioned with respect to each other to define a central open chamber inside both of said windings and having an outer boundary generally defined by one of said windings, the improvement comprising: an axially movable core structure positioned in said central chamber, said core structure comprising a closed housing formed from non-magnet, nonconductive material with an outer wall generally matching said boundary and an internal cavity, a layer of high permeability material adjacent a major portion of said outer wall, said layer defining a core chamber and means for circulating a coolant through said core chamber and into contact with said layer.
2. The improvement as defined in claim 1 wherein said layer comprises a plurality of separate, elongated rod-like elements extending generally axially of said windings.
3. The improvement as defined in claim 2 including means for varying the effective axial length of said elements in said chamber to vary the output energy induced into said secondary winding.
4. The improvement as defined in claim 3 wherein said varying means includes means for moving said elements in a direction axially of said windings.
5. In a radio-frequency transformer for an induction heating device including a primary winding and a secondary winding, said windings each being generally cylindrical and having a central axis, and means for fixedly securing said windings in a telescopical, coaxial relationship, said transformer having a central opening inside both of said windings and having an outer boundary generally defined by one of said windings, the improvement comprising: a core structure mounted within said chamber, said core structure including a closed, non-magnetic housing haVing an outer wall generally matching said boundary and spaced therefrom, a layer of high permeability material adjacent a major portion of said outer wall and in the form of a plurality of high permeability elements secured within said housing and adjacent said outer wall, and means for circulating a coolant through said housing and in heat transfer relationship with said elements.
6. The improvement as defined in claim 5 wherein said elements are elongated and extend in a direction generally axially of said windings.
7. The improvement as defined in claim 6 wherein said housing includes means engaging the respective ends of said elements for securing said elements adjacent said outer walls of said housing.
8. The improvement as defined in claim 7 including means for adjusting said housing in a direction axially of said windings whereby the magnetic coupling between said windings is varied.
9. The improvement as defined in claim 7 wherein said housing has axially spaced closure plates and said securing means includes means on said plates for engaging said respective ends of said elements.
10. The improvement as defined in claim 9 wherein said engaging means are inwardly extending flanges on said plates.
11. The improvement as defined in claim 5 including means for adjusting said housing in a direction axially of said windings whereby the magnetic coupling between said windings is varied.
12. The improvement as defined in claim 5 including means for draining coolant from said closed housing.
13. A radio-frequency transformer for use in an induction heating installation, said transformer including a generally cylindrical, multi-turn primary winding having a central axis and a generally cylindrical inner periphery; a generally cylindrical, single turn secondary winding having a central axis and a generally cylindrical outer periphery; said primary winding being smaller than said secondary winding and being telescopically received within said secondary winding in a coaxial, radially spaced position to define an air gap between said primary and secondary windings, a plurality of elongated high permeability elements positioned parallel to the axes of said windings and adjacent one of said peripheries, a housing surrounding said elements; means for circulating a coolant in said housing and around said elements; and, means for adjusting the axial position of said housing within said windings.
